The inventive connection device consists of a connecting clip (1) which is simultaneously inserted into a receiving fixture for said connection clip (1) in two components (A,B) that are to be connected. The connection clip is anchor-shaped and basically consists of a rod (2) and an anchor bar (4) extending perpendicularly thereto. The free end of the rod (2) is configured as a snap-in element (5). The ends of both sides of the anchor bar (3) are bent and form insert sections (25). The receiving fixture for the connection clip consists of both a groove (20) which is provided on one side of a component that is to be connected, whereby said groove is open on one side, and an insert receiving fixture (25) that extends close to the groove (20) inside the component that is to be connected. When two components that are fitted with said receiving fixture for a connection clip are connected, they are placed adjacent to each other in such a way that both grooves (20) form an opening, whereby the rod (2) of the connection clip and the snap-in element thereof are introduced into said opening. The insert sections (4) simultaneously engage with the insert receiving fixtures (25). The snap-in elements (5) on the connection clip (1) engage with (5) an undercut (24) provided in the groove (20), whereby the connection becomes non-detachable.

Description

The present invention relates to a connecting clip for connecting at least two building parts, as well as a holder, an electrical device and an electrical building part, according to the claims.

The invention should preferably be used to connect electrotechnical components such as circuit breakers, circuit breakers, residual current circuit breakers, etc. Admittedly, it should already be noted here that the application is not limited to only electrotechnical articles. Rather, this area will only be explored here as an example, as the selected design examples at this time have been used within this area.

When installing a large number of electrotechnical building parts, these often have to be arranged next to each other in junction boxes and connected to each other. Until now, this took place either through continuous riveting or with the help of so-called spectacle springs that hold two construction parts that are placed next to each other together when the coiled spring ends engage in corresponding recesses in the construction part and the spectacle spring's hoop grasps both construction parts and thus connects them together.

But this connection has several disadvantages. Firstly, the assembly is relatively difficult, as great skill is required to place the eyeglass spring parts in the recesses on the building parts to be connected together, without thereby losing the eyeglass spring. This made installation more difficult, took longer and was thus also more expensive. Furthermore, the two individual components that were to be connected together were only aligned through the facility for the two side surfaces towards each other. However, a further device was necessary, for example in the form of a centre.

For literature within the subject area, reference is made to German small patent DE 29 804 284.

It is therefore a task for the present invention to create a connection device which is able to connect several individual components to each other in a simple way, whereby at the same time the following advantages are to be achieved, the assembly is to be simple, time-saving and thus cost-effective, the connection between two building parts must be stable and at the same time ensure a centering, furthermore the connecting device must no longer be easily detached.

Furthermore, a connection device must be as functional as possible in order to be connected together with several different connection elements.

This task is solved with the present invention as it is defined with the features listed in the claims.

In detail, significant advantages of the subject invention and also its advantageous further development will now be briefly explained.

Through the snap-on connection to the connection clip in the connection clip holder, the assembly of two individual components becomes extremely simple. Furthermore, the connection between two construction parts is made insoluble by clipping the snap hooks into the inwardly sloping areas of the track, above all as the inwardly sloping areas into which the connecting clip's snap hooks are clipped in the assembled state are located in the interior of the two construction parts and are thus no longer accessible from the outside.

As the connection clip holder's groove in a single component has a recess that roughly corresponds to half the thickness of the rod of the connection clip, the rod of the connection clip engages when the connection clips are inserted into the two grooves of the connection clip holder at the same time as two individual components are abutting each other. Furthermore, the snap hooks of the connecting clip clip into both of the inwardly sloping areas of the slots for both of the individual components to be connected to each other. Thereby, the construction of the connecting clip is simplified and its manufacturing costs can be kept low.

Furthermore, by the fact that the pin-like anchor rod's insertion sections in the connection clip are inserted into suitable insertion holders for individual components to be connected to each other, a simple fixation of both individual components in a direction across the insertion direction is achieved. At the same time, the connecting clip with its two insertion sections ensures correct positioning of both individual components in relation to each other.

Through recesses on the outside, which are arranged in the bent area of the anchor bar at the transition of the insertion sections, it is possible to shape the pin-like insertion sections somewhat flexibly, so that an expansion of these insertion sections in relation to the rod is possible. The same is achieved with a material recess in the inner corner area in the bend between the anchor beam and the insertion section.

The slots and plug-in holders in the connection clip holder can be taken into account in a simple way when manufacturing the individual components, so that their manufacturing costs are small.

According to another aspect of the invention, it is possible to shape the connection clip holders multifunctionally. Thereby, different connecting clips can be used optionally to connect two construction parts to each other.

The invention is explained in more detail with the help of the subsequent descriptions for detailed design examples with reference to the figures.

Figure 1 shows the connecting clip in a perspective view and also a single component to be connected that has the connecting clip holder, Figure 2 shows a single view of the connecting clip in perspective, Figure 3 shows the connecting clip in perspective in the built-in state in a single component to be connected, which is equipped with a corresponding connection clip holder, figure 4 shows in section along the line IV-IV in figure 3 with the parts of two individual components to be connected to each other, figure 5 shows in perspective another connection clip, figure 6 is seen in perspective two individual components to be connected with each other and also the connecting clip from Figure 5, where both individual components are produced partially broken down and one of the individual components is, in addition to this, only partially produced, Figure 7 shows the same as Figure 6, but where the connecting clip is in its clipped state, Figure 8 a another presentation in perspective of Figure 7.

In what follows, a first design example is explained with reference to figures 1-4.

First, the connecting clip 1 is described with the help of figure 2.

The connection clip essentially has an anchor-shaped design. Consists of a rod 2 and an anchor beam 3 which at one end of the rod is designed across it in one piece. The rod 2 and the anchor beam 3 have an essentially right-angled cross-section and are arranged so that the rod 2 is aligned on the high side of the anchor beam 3.

The rod 2 has a snapper element 5 at the other end. The snapper element 5 consists of a V-shaped recess 7 which is open at the lower end of the rod 2 and runs together inwards. Through that, foot halves arise. Snapper hooks 11 are arranged on these foot halves, which protrude on the side of the rod that faces away from the V-shaped recess 7. These snapper hooks 11 have an inclined surface 13 as an assembly aid to facilitate the insertion of the connecting clip into a corresponding groove in the individual component must be connected to during the later assembly. Through the V-shaped recess 7, the rod 2 in the lower area is flexible and can be compressed somewhat when it is pushed into a groove that is somewhat smaller than the foot part. Through this, an insertion into a recess is made possible, where the width is somewhat smaller than the width that the foot part with the snapper hooks would be, as the snapper hooks are simply bent inwards to adapt to the width of the recess.

The anchor beam 3 has in both end areas a right-angled bent pin-like insertion section 4 which in approx. 90° is bent so that it extends parallel to the rod 2.1 the angle area, a recess 10 is arranged on the inner side, in order to equip the pin-like insertion sections with a certain flexibility.

In the following, a connecting clip holder will be explained in more detail, which is arranged in a building part A, B which is to be connected to each other and which is to hold the connecting clip. Here, special reference is made to Figure 1.

The connecting clip holder is arranged twice and is located on two sides which are directly opposite each other on a building part A, B which is to be connected to each other. Through this, a building part to be connected can be connected to either the right or the left or simultaneously on both sides with one or two building parts to be connected to each other. Such a side is brought into contact with a corresponding side on another single component B and with the connecting clip 1 both building parts are fixed together (see figure 4).

The connection clip holder consists of a groove 20 which, on a side surface of the individual component A to be connected to, is designed so that it is open at one end. This track essentially runs longitudinally from a push-in side which, namely, goes out from the open track side. Here, at the open beginning of the track, an inclined area 23 is arranged as a mounting aid which serves for an easier insertion of the connecting clip. Then follows an insertion section 21 which has a groove width that roughly corresponds to the width of the rod of the connecting clip to be pushed in. But since the connecting clip has a snapper hook 11, the width of which extends beyond the normal width of the rod 3, the snapper hooks 11 are pressed somewhat together when passing through the insertion section 21. This compression is possible through the V recess 7. A snapper section 22 connects to this insertion section 21.

The snapper section 22 has an inwardly sloping area 24, the width of which is greater than the width of the insertion section 21. Thereby, the snapper element, after the compressed state in the insertion section 21, can again expand in the inwardly sloping area.

In the following, the assembly of two individual components is described. Two simple building parts A, B that are to be connected to each other are placed against each other with two sides (see figure 4), each of which has connecting clip holders. Thereby, the two slots 20 create an opening similar to a bag opening which is extended at the end by the inwardly sloping area 24 to the snapper section 22. When the connecting clip is pushed into the slot 20, the snapper hooks 11 on the snapper element 5 are flexibly pressed together. The connecting clip is pushed in so far that the snapper hooks 11 snap into the inwardly sloping area 24 in the groove 20 in the connecting clip holder, i.e. that the snapper hooks 11 are formed from their compressed positions back to their normal positions.

At the same time, the pin-like insertion sections 4 on the anchor beam 3 are pushed into corresponding insertion holders 25 which are additionally designed in the connection clip holder. Here, the possible measurement inaccuracy that may exist both for the connecting clip and also for the connecting clip holder is compensated through the flexibility of the pin-like insertion section 4. Flexibility is added through the material recess 10 which has already been described.

When the snapper hooks 11 of the connecting clip 1 snap into the snapper section 22 in the groove 20 of the connecting clip holder, the connection becomes insoluble as the snapper hooks in the inwardly sloping area are no longer accessible. Through the simultaneous introduction of the pin-like insertion sections 4 into the corresponding insertion holders 25, an alignment of all the parts in relation to each other is achieved.

Now follows the description of a second design example of the present invention.

In the following, one more specialty of this design example will be discussed, namely that the connection holder can be used several times. It is not absolutely necessary that the connecting clip be used according to the present invention. In principle, it is also conceivable to use another connecting clip. To make this possible, the present and so far described connecting clip holder is elegantly designed so that both connecting clips of the type described so far, as well as a connecting clip of another type can be used. T such other connecting clip is shown in Figure 5. Figures 6-8 show how the connecting clip according to Figure 5 is inserted into the connecting clip holder.

With reference to Figure 5, the connecting clip 1-1 will now be explained in more detail.

The connecting clip 1-1 has a substantially anchor-shaped construction which has a rod 3-1 and also an anchor beam 4-1 which extends transversely over one end of the rod. Both the rod 3-1 and the anchor beam 4-1 are designed flat and have a right-angled cross-section. At the other end of the rod, directly opposite the anchor beam 4-1, there is a swivel foot 2-1 which is designed as a round wave section that protrudes on the sides to the right and left of the rod 3-1. The axis of rotation of the swivel base is perpendicular to the longitudinal axis of the anchor beam 4-1. Moreover, the axis of rotation of the pivot foot 2-1 is aligned across the longitudinal extent of the anchor beam 4-1. Approximately in the middle of the rod 3-1, a pin 5-1 is arranged which extends parallel to the axis of rotation of the pivot foot 2-1 and thus also protrudes somewhat on the side of the rod 3-1. The anchor beam 4-1 has a slightly curved curved snapper section 4a-1 which curves towards the rod 3-1. This snapper section 4a-1 serves as a snapper element during assembly. Through a suitable design of the anchor beam, for example through a recess in the middle of the anchor beam, the tip of a screwdriver can be used to dismantle the device.

As can be seen from Figure 6, two building parts which are to be connected to each other are designated 13-1 and 14-1, whereby for example building part 13-1 is a main device and building part 14-1 is an auxiliary device which must be mounted on the main device.

In each of the two building parts 13-1 and 14-1 which are to be connected to each other, a connecting clip holder is arranged and also arranged on each side to the left and to the right two recesses 11-1 in the connecting clip holder.

In the following, the connection clip holder is described.

As can be seen from Figure 6, a track 7-1 is arranged on one side of the building part 13-1 and 14-1 which extends along the entire side. Track 7-1 is open at both ends. An inwardly inclined area 9-1 is arranged in the groove, so that the groove 7-1 together with the inwardly inclined area 9-1 forms a kind of guide groove, where the swivel foot 2-1 on the connecting clip 1-1 is held and as on the right and left is stored sliding shifter. Here, the pivot foot 2-1 is located in the inwardly sloping area 9-1, while the rod 3-1 is guided in the groove 7-1. The anchor beam 4-1 is located outside the track 7-1. As the swivel foot 2-1 is guided in the inwardly sloping area 9-1, the connecting clip cannot possibly fall out of the groove, so that it can no longer be lost. The pin 5-1 prevents the anchor beam 4-1 from accidentally ending up in the interior of the building part 13-1 through the slot 7-1, where it would not be accessible from the outside.

In the following, the engagement recess in the building parts 13-1 and 14-1 is described.

These serve to receive and hold the snapper section 4a-1 on the connecting clip 1-1, so that a solution is no longer immediately possible. For this, a recess 11-1 is designed both to the left and to the right on the side of the track 7-1 in the construction parts 13-1 and 14-1. This recess 11-1 is substantially designed corresponding to the shape of the snapper section 4a-1 on the anchor beam. That is that it consists of a construction surface which extends roughly perpendicular to the extent of the track 7-1 into the interior of the construction parts 13-1, 14-1. At the end, this contact surface has an inwardly sloping area which roughly corresponds in shape to the curved snapper section 4a-1 of the connecting clip 1-1. When assembling the two building parts that are to be connected to each other, the snap section 4a-1 can be clipped into the recess 11-1 and snapped into the inwardly sloping area. Depending on the design of the recess and the setting of the material flexibility of the connecting clip, the locking function can be set from very strict and difficult to undo to very light and easy to undo.

In the following, the connection for the two building parts 13-1, 14-1 through the connection clip 1-1 is described.

Figure 6 shows an illustration, where the connection clip 1-1 is arranged in a component 13-1 to be connected, and which is in the open position. The construction part 14-1 which is to be connected to the construction part 13-1 is in a construction position in which the two construction parts are to be connected to each other. Expressed more precisely, the pivot foot 2-1 on the connection clip 1-1 is arranged in a right-angled pivot foot bearing 12-1 in the one building part 13-1 to be connected. To make this easier to understand, the upper cover on the building part 13-1 to be connected, where the connecting clip 1-1 is located, is partially broken open, so that the entire connecting clip can be seen. In reality, the rod 3-1 of the connecting clip 1-1 is naturally located together with its pivot foot 2-1 in the interior of the building part 13-1 to be connected, and only a part of the rod 3-1 and the anchor beam 4-1 protrude from a slot-like opening in slot 7-1 in building part 13-1 to be connected. The connecting clip 1-1 is rotatable about its swivel base 2-1. If the connecting clip 1-1 is now turned around the pivot foot 2-1 in the direction of arrow A from figure 6, then the connecting clip engages with the second building part 14-1 to be connected, as shown in figure 7.1 figure 7, the connecting clip is in its closed position .

As can be seen with the help of Figures 6 and 7, the two building parts 13-1 and 14-1 are similarly designed with regard to the design of the holder for a connecting clip. That is one can flexibly and optionally engage the connecting clip 1-1 on the building part 13-1 in connection with the building part 14-1 with the corresponding holder that is arranged there and conversely one could bring into engagement a connecting clip that is arranged in the building part 14-1 with the holder which is arranged in the construction part 13-1. With the reference 12-1, a swivel foot bearing is named which serves to support the swivel foot 2-1 in two directions, whereby the connecting clip 1-1 remains rotatable about the axis of the swivel foot 2-1. The swivel foot bearing 12-1 is formed by a wall section 12a-l and another wall section 12b-l. The wall section 12a-l is not designed as high as the wall section 12b-l. The wall section 12a-l is formed as the inwardly sloping area 9-1 in the groove 7-1 ceases before the end of the groove. The wall section 12a-l is necessary so that the pivot foot 2-1 can come into contact with it, but the rod 3-1 can slide over this wall section 12a-l in order to be able to engage in the construction part 14-1 to be connected at all ( see figures 6 and 7). The wall section 12b-l is designed so high that the rod 3-1 also comes into contact with this wall section, so that the rotation of the connecting clip is limited by this wall section. This ensures that the connecting clip cannot swing further inwards, where, depending on the circumstances, it is no longer accessible to the installation staff.

Adjacent to the wall section 12b-l, there is at right angles to this recess 11-1 with the inwardly sloping area which is designed corresponding to a snappert side on the snapper section 4a on the anchor beam 4-1 on the connecting clip 1-1. When now the connecting clip 1-1 is turned around the axis of rotation on its pivot foot 2-1, as can be seen in figures 6 and 3-1, the connecting clip can be turned so far that it comes into contact with a contact surface on the rod 3-1 the wall section 12b-l and the curved snapper section 4a-1 are clipped into the inwards sloping area of the recess 11-1. This state is shown in Figure 7. In this state, in the present design example, auxiliary and main apparatus 13-1, 14-1 are firmly connected to each other. The dimensions of the connecting clip in connection with a suitable selection of the dimensions of the recess 11-1 in the building part to be connected have been chosen so that the connecting clip, when inserted, spans both building parts to be connected to each other.

As can be seen from Figure 7, the snapper section 4a-1 sticks to the anchor beam of the connecting clip which is directly opposite the clipped snapper section 4a-1 in the slot 7-1 of the auxiliary device 14-1, through which the connecting clip 1-1 could be swung inwards. Thereby, the connection clip in its closed position is accessible from the outside, at least for an auxiliary tool such as a small screwdriver. Through this, the connection between the two building parts can again be dissolved. Thus, the auxiliary device is easy to place on the main device and just as easy to detach again.

As can be seen, for example, from Figures 4 and 5, the connecting clip on the anchor beam 4-1 in the middle opposite the rod 3-1 is equipped with a V-shaped recess 6-1. This recess 6-1 allows an even easier release of the connecting clip by means of an auxiliary tool, to move the clipped snapper sections 4a-1 in the inwardly sloping area 11-1 from the closed position to the open position. For example, a small screwdriver can be gripped into the recess and thus the connecting clip can be pressed out.

As can further be seen from figure 8, where the auxiliary device is shown in its entirety (i.e. without partial interruptions), the connecting clip can be freely moved inside the slot 7-1 from right to left and vice versa, so that it can optionally be moved from a swivel foot bearing 12-1 on one side to another on the other side. Thereby, a main device 14-1 can optionally be mounted on the auxiliary device 13-1 to the right and/or to the left. This ensures maximum flexibility during installation.

As can further be seen from Figure 6, the pin 5-1 on the connecting clip 1-1 serves to prevent the connecting clip from accidentally disappearing completely into the slot 7-1 in the building part 13-1 to be connected, when the connecting clip is located somewhere in the middle of the groove 7-1, in which the pin 5-1 receives against the walls of the building part 13-1 which forms the groove 7-1. Thus, the anchor beam 4-1 on the connecting clip cannot be swung completely into the building part, i.e. the turning area is in the middle area, i.e. in the area that is not on the sides, more restricted than in the side areas, where the groove 7-1 is open and allows a swing of the connecting clip 1-1, until the rod 3-1 comes into contact with the contact surface 12b-l.

In addition, on each side of the adjacent side surfaces of the building parts 13-1, 14-1 which are to be connected to each other, there is a partially withdrawn area 8-1. If two building parts that are to be connected to each other are placed against each other, the two adjacent retracted areas 8-1 create a track 10-1. When the connecting clip is brought to the closed position, i.e. when the connecting clip is swung to its closed position (in the direction of arrow A in Figure 6), then the already described pin 5-1 swings into this slot 10-1. Thus, firstly, the pin 5-1 does not prevent an assembly of the two construction parts that are to be connected to each other, secondly, it can also serve as a guide. In order to make it possible for the pin 5-1 to be swung into the slot 10-1, inclined areas 15-1 are arranged on each of the corners as an assembly aid. Of course, it is not a question of purely oblique relief areas. Rather, a rounding or any other suitable shape may also be provided to allow the pin 5-1 to enter the pivoted position unhindered.

As can be seen from a comparison of the first design example in figures 1 to 4 with the second design example in figures 5 to 8, the connecting clip holders in the two design examples are designed the same. They are designed so that both connecting clips can be inserted optionally. That is to say, several functional surfaces on the connecting clip holders have a double function, namely firstly as holders for connecting clips in the first design example and secondly to hold the connecting clip in the second design example.

Here, for example, sections of track 10-1 in the second design example correspond to sections of track 22 in the first design example. Furthermore, it can be seen, for example, from Figure 4 that the plug-in holders 25 for holding the plug-in section 4 in the connection clip in the first design example are designed with an inwardly sloping area 27 which corresponds to the inwardly sloping area 11-1 in the connecting clip holder in the second design example. Furthermore, it appears from Figure 1 that the connecting clip holder in the first design example has a groove with an inwardly sloping area as is necessary to hold the connecting clip 1-1 in the second design example.

In summary, it can be said that the connection clip holder in both of the design examples described above has all the characteristic features that are necessary for an optional connection clip holder for the first or the second connection clip. Thus, the construction of the connection clip holder is multi-functional.

The connecting clip can be made of plastic. Here, a plastic injection technique can be used, which makes it possible to design the connecting clip in one piece and thus ensure a cost-effective production. The same applies to the production of the connecting clip holder, where the production can be taken into account already during the production of the construction parts that are to be connected to each other.

Through the appropriate choice of plastic, connecting clips can also be provided with the desired flexibility. By anticipating the connecting clip holders on two sides of a building part A, B which are to be connected to each other and which lie directly opposite each other, the individual components can be joined in series with an optional number.

The invention described above is especially designed for electrical switching devices such as line protection switches, fault current protection switches, auxiliary switches or the like. Preferably, then, all devices in a series are equipped with connecting clip holders of the above-mentioned type, so that they can be assembled into desirable functional units.

If, for example, a functional unit of three or four circuit breakers is to be formed, these devices are connected with non-detachable connecting clips according to the first design example. In order to achieve the desired stability, all circuit breakers have, for example, three clip holders. Here, one could be arranged in the area of the connection terminals, as shown in the figure, and one at the bottom of the device.

If, on the other hand, an auxiliary switch is to be combined with a line protection switch, the auxiliary switch is already equipped during manufacture with, for example, two detachable connection clips according to the second design example and then clipped into the connection clip holder of the line protection switch.

Of course, here all the clip holders on the devices in a series must have the same height, as the devices to be connected to each other can then be arranged on the same mounting rail.
