The object of the present invention is to provide an assembly for connector members which makes it possible to use metal connector housings in an easy and advantageous manner.

This problem is solved by an object having the features of claim 1.

According to it, the assembly has a grounding element arranged on the insulator, which grounding element has a housing contact part, the grounding contact element arranged on the plug part and the mating connector member. Is electrically connected for ground contact with and the housing contact portion is configured to electrically contact the connector housing when the contact insert is connected to the connector housing.

According to it, when the contact insert is fitted into the connector housing, the connector housing is brought to ground. This is done through a grounding element, which on the one hand has a housing contact part for electrical contact of the connector housing, and on the other hand is electrically connected to a grounding contact element, so that through the grounding element, with the connector housing. An electrical connection exists with the ground contact element. The ground contact element to which the ground wire can be connected reaches the ground contact with the mating connector member during the plug-in connection between the connector member and the mating connector member, whereby the connector member and the mating connector member, The same ground potential exists.

The insulator is preferably integrally molded, for example from a plastic material. The insulator has an electrically insulating effect and in this way insulates the contact elements arranged in the insulator from the connector housing, which is preferably made of a conductive material.

The use of a grounding element can make a grounding contact with the connector housing in an easy manner. For example, when fitting the contact insert into the connector housing, the contact may be automatically formed, thus eliminating the need for an additional mounting step to form the ground contact.

In one embodiment, the ground contact element extends along the plug-in direction and, when the connector member and the mating connector member are plugged into each other, grounding along the plug-in direction while grounding along the mating direction. It contacts the other contact element provided. Thus, during a plug-in connection between the connector member and the mating connector member, the ground contact element is superimposed on the arranged mating contact, thereby forming a ground contact.

In one embodiment, the housing contact portion extends planarly along a plane extending transversely to the insertion direction. Thus, the housing contact portion provides a contact surface which, when the contact insert is fitted, makes a planar contact with the connector housing and further forms an electrical contact between the grounding element and the connector housing.

According to another embodiment, the housing contact portion may be provided with at least one locking position for mechanically locking the contact insert to the connector housing. In this case, the housing contact part is used not only for electrical contact between the grounding element and the connector housing, but also for mechanical fixing of the contact insert with the connector housing.

The housing contact part may for example be configured as a flange and project from the insulator. Thus, through the housing contact part, on the one hand, an electrical contact between the grounding element and the connector housing can be made, and on the other hand, the mechanical fixing of the contact insert in the connector housing can be made.

In another embodiment, the housing contact part may be arranged in the region of the fixed part of the insulator which extends transversely to the insertion direction and which is operatively connectable to the connector housing while supporting it. The fixed part of the insulator can be molded on the insulator, for example as a ledge (for example in the form of a step), and when the contact insert is fitted in the connector housing, it can be supported in the connector housing, so that through the fixed part, the connector Mechanical fixing of the contact insert within the housing can be formed. The fact that the housing contact part is arranged in the region of the fixed part ensures that there is an electrical contact between the housing contact part of the grounding element and the connector housing when the contact insert is fitted into the connector housing. Has been done. In this case, the housing contact part may, for example, be configured as a flange and be attached to the fixed part of the insulator. However, it is also conceivable that the housing contact part is, for example, fitted into the fixed part of the insulator.

A wide variety of variations of the grounding element and the grounding contact element connected to the grounding element are conceivable and possible.

In a first variant, the contact element may carry an additional function, eg coding. Coding is understood to be the mold part of the insert part of the connector member, which ensures that the connector member can only be plugged in at a certain position and orientation and connected with the mating connector member. Such a coding can be formed, for example, by a web extending along the insertion direction, which web is arranged unevenly distributed in the insertion part, whereby the arrangement of the connector members is arranged. Force the correct mounting of the mating connector member in terms of position and orientation.

If the ground contact element has the additional function of coding, in so-called male connector members, the ground contact element extends, for example, on the outer surface of the plug-in part, and for coding purposes lies transverse to the plugging direction. In addition, it may protrude from the insertion portion. The ground contact element then extends over the bayonet portion, preferably along the bayonet direction, whereby the ground contact element forms a protruding web outside the bayonet portion, which web is , Can be engaged with the surface of the mating connector member during plug-in connection with the mating coding provided.

Alternatively, in so-called female connector members, the ground contact element may also be arranged on the inner surface of the bayonet part in the region of the coding element. Again, the ground contact elements are components of the coding and may extend, for example, between the webs on the radially inwardly projecting inserts.

In this variant, the ground contact element is, for example, integrally molded on the ground contact element, whereby the ground contact element extends, for example, in the form of a pin from the ground contact element along the bayonet. There is.

In another variant, the ground contact element is surrounded by the bayonet. In this case, the ground contact element is arranged in the plug-in part, for example as a separate component from the grounding element, is mechanically retained, for example in the plug-in part, and is fixed, for example, in the plug-in part. In this case, the ground contact element may be configured, for example, as a contact pin or a contact socket, and when the connector member and the mating connector member are plugged into each other, the mating contact element on which the mating connector member is arranged is arranged. Leads to a connection involving electrical contact with the element.

In this case, the grounding element is used for the electrical connection between the grounding contact element, which is arranged inside the plug-in part, and the connector housing which surrounds the insulator. The ground element can, for example, have a contact part for electrical connection with a ground contact element, which contact part is connected to the housing contact part through the connection part. The contact portion is electrically connected to the ground contact element and may have, for example, an opening through which the ground contact element extends. The connecting part has, for example, the shape of a current bar and forms an electrically conductive connection between the contact part and the housing contact part of the grounding element.

In that case, in one embodiment, the contact part may be bent with respect to the connection part and/or the connection part may be bent with respect to the housing contact part. For example, the housing contact portion may extend planarly along a plane that extends transversely to the insertion direction, while the connecting portion may, for example, be transverse to the insertion direction and transverse to the insertion direction. And may extend along a plane formed by the directions. The connecting portion may be bent and/or bent multiple times.

For example, the connecting part extends between the housing contact part and the contact part, enclosing the body part of the insulator, for example the body part on which one or more contact elements of the contact insert are held. It is possible to The housing contact part can extend transverse to the insertion direction, for example like a flange. The connecting part may form a connection between the housing contact part and the contact part and thereby a ground contact element, for example like a current bar.

In one embodiment, the contact portion connecting the grounding element to the grounding contact element is configured to be resilient and is in electrical contact with the grounding contact element. Therefore, the contact portion is configured like an elastic switch and is used to form an electrical contact between the ground contact element and the ground element.

The ground element has, for example, two contact portions, for example facing each other, which contact portion receives the ground contact element between itself and thus forms an electrical contact with the ground contact element.

In another embodiment, two grounding elements are provided, each grounding element having a housing contact portion and a contact portion connected to the housing contact portion through a connecting portion, such as an insulator. Are located on the opposite sides of. The contact part of the grounding element then receives the grounding contacting element between itself and in this way forms an electrical contact between the grounding contacting element and both grounding elements, whereby the grounding element is Contact the ground contact elements together.

Each grounding element may be arranged at its housing contact part on a fixed part of the insulator and may be supported by the arranged fixed part.

In one embodiment, the grounding element is attached to the insulator of the contact insert as a mounting member. In the mounted position, the grounding element is held on the insulator, for example in a form-fitting manner.

In another embodiment, the grounding element may be insert molded with an insulating (plastic) material, in which case the housing contact portion is exposed for contact with the connector housing, and the contact portion is also , Exposed for contact with a ground contact element, whereby an electrical connection can be formed. Thus, the grounding element is fitted into the injection mold during the manufacture of the insulation and the material is insert molded by injection molding.

In yet another embodiment, the grounding element may be molded onto the insulator as a metal injection molded part. Such metal injection molded parts can be manufactured directly on the insulator by injecting a metal alloy into the recess of the insulator. For this purpose, for example, eutectic alloys with a low melting point can be used. Alternatively, it is possible to form a precast of such a metal injection-molded part and then insert-mould or recast it with a (plastic) material to form an insulator.

Another, possibly possible method for producing the grounding element is also considered a metal powder injection molding process (MIM from English Metal Injection Molding) in which fine metal powder is mixed with an organic binder and molded. To be done. Subsequent sintering causes the grounding element to be compressed, which results in a high-density solid metal part, which can then be insert-molded with an insulating material.

In yet another embodiment, the grounding element may be arranged on the cover element connected to the insulator. The cover element may, for example, be attached to the end of the insulator facing away from the plug-in part and is, for example, form-fittingly connected to the insulator, for example through a fixing plate which is fixedly connected to the insulator. You can stay. By means of the cover element, for example, the contact element can be held on the insulator and supported against it.

The grounding element can then be held in a form-fitting manner between the cover element and the insulator. For this purpose, the grounding element may be received, for example, on the cover element, so that when the cover element is mounted on the insulator, the grounding element is located between the cover element and the insulator. Therefore, it is held in a fixed position with respect to the insulator.

Alternatively, the ground element may be insert molded, for example with the material of the cover element. In this case, the cover element is molded by injection molding (from plastic), during which the grounding element is fitted into the injection mold and insert molded with the material of the cover element.

The grounding element can project into the cover element, e.g. transversely to the insertion direction, whereby the housing contact part of the grounding element projects laterally and when the contact insert is fitted into the connector housing. It may be in electrical contact with the inner wall of the connector housing.

In a particular embodiment, the grounding element has, for example, a connecting part extending transversely to the insertion direction, the connecting part comprising a housing contact part and a grounding part arranged at the connecting part. A contact tab is arranged for electrical connection with the contact element. In this case, the connection part provides a current bar for the electrical connection of the housing contact part and the contact tab. The contact tabs abut, in a supporting manner, the arranged ground contact elements, so that there is electrical contact with the ground contact elements through the contact tabs.

In an advantageous embodiment, the housing contact part is elastic in the insertion direction. This in particular allows the housing contact portion to slide on the inner wall of the connector housing while the contact insert is in electrical contact with the connector housing when the contact insert is fitted into the connector housing.

The assembly is preferably a component of a connector member, especially a component of a heavy connector member, for use in a highly loaded environment. By choosing from a wide variety of contact inserts, it is possible in this case to form modular connector members, which connector members are adapted in a specialized manner for their particular use, for which reason the contact elements are With a suitable mating surface with the assembly of.
