This is to connect the wiring pattern 2 of the wiring board 1 using a detachable connector 10. The wiring substrate 1 is formed by laminating a resin or the like, and has a plurality of pairs (five in the embodiment) of a pair of wiring patterns 2 connected to each other. Connection terminations 3 are arranged in line on the surface 1 a of the edge 4 of the wiring board 1,
The connection termination 3 on the other side of each wiring pattern 2 is arranged in a line symmetrically with the back surface 1 b and the front surface 1 a of the edge 4 of the wiring board 1.

The connector 10 includes a plurality of substantially U-shaped conductive wires 11 that short-circuit connection ends 3 of a pair of wiring patterns 2 on the front and back sides connected to each other, and a plurality of conductive wires 11. And a holding block 12 made of insulating resin. The holding block 12 is molded into a substantially rectangular parallelepiped shape, and the bent portion 11a side of the conductive wire 11 is buried integrally at the time of molding, and the contact portion 11b contacting the connection end 3 of the wiring pattern 2 is exposed and protrudes.

In this connection structure, the connection termination 3 of the wiring pattern 2 is provided at a required connection position of the connector 10.
And a positioning means 13 for restricting the movement of the connector 10 in the row direction R. This positioning means 13
It is formed in a rectangular recess 14 which is recessed at the edge 4 of the wiring board 1 and into which the holding block 12 of the connector 10 is removably fitted. When the connector 10 is fitted, the side end surface 12 a of the holding block 12 is
a, the movement of the connector 10 in the row direction R of the connection end 3 of the wiring pattern 2 is restricted.

Further, in this connection structure, the connection termination 3 of the wiring pattern 2 is provided at a required connection position of the connector 10.
A first locking means 20 and a second locking means 25 for restricting the movement of the connector 10 in a direction orthogonal to the row arrangement direction R. The first locking means 20 regulates the movement of the connector 10 in the removing direction F (the surface direction of the wiring board 1), and
And the engaging protrusion 21 provided on one of the recesses 14 (the holding block 12 in the embodiment) and the connector 10
And the engaging concave portion 22 that is provided in one of the holding block 12 and the concave portion 14 (the concave portion 14 in the embodiment) and the engaging convex portion 21 is engaged when the holding block 12 is fitted. . More specifically, the engaging protrusion 21 is provided in a semi-cylindrical shape at the center of the side end surface 12 a of the holding block 12, while the engaging recess 22 is formed on the side wall 14 a of the recess 14. It is recessed in the same shape as. The second locking means 25 regulates the movement of the connector 10 in the direction G perpendicular to the surface of the wiring board 1, and is provided on each of both side end faces 12 a of the holding block 12. A pair of projecting pieces 26 projecting up and down and holding the wiring board 1
It is provided with.

Therefore, the wiring pattern 2 of the wiring board 1
Is connected, the holding block 12 of the connector 10 is used.
Is fitted into the recess 14 of the wiring board 1 as the positioning means 13 so that the contact portion 11b of the conductive wire 11 contacts the connection end 3 of the wiring pattern 2. In this case, the connection end 3 of each pair of wiring patterns 2 on the front and back that are connected to each other contacts the corresponding conductive line 11 and is short-circuited.
In addition, since the wiring board 1 is somewhat elastically deformed, the engaging projection 21 of the first locking means 20 is engaged with the engaging recess 22. Further, a pair of projecting pieces 26 on the left and right sides of the second locking means 25 sandwich the wiring board 1.

In this connection state, the holding block 1
2 is in contact with the side wall portion 14 a of the recess 14, and the movement of the connector 10 in the row direction R of the connection end 3 of the wiring pattern 2 is regulated. Since the contact with the corresponding conductive wire 11 does not shift and so-called pitch shift does not occur, a situation where connection is insufficient is prevented. In addition, since there is no contact shift, there is no need to move the connector 10 for positioning each time, so that the connection work is easy and the work efficiency is improved.

Further, in the first locking means 20, since the engaging projections 21 are engaged with the engaging recesses 22, the movement of the connector 10 in the removing direction F is restricted. Thus, the connection state can be maintained without welding as in the related art. Further, in the second locking means 25, the pair of left and right projecting pieces 26 sandwich the wiring board 1, so that the movement of the connector 10 in the direction G perpendicular to the surface of the wiring board 1 is restricted. Is ensured. That is, since the wiring board 1 is also held by the contact portions 11b projecting up and down of the conductive wire 11, the holding is ensured by this alone, but the load on the conductive wire 11 is reduced by the holding of the protruding piece 26. At the same time, since the strength of the protruding piece 26 can be made higher than that of the conductive wire 11, the holding can be reliably performed, and the connection state can be maintained without welding as in the related art. In order to release the connection, the connector 10 may be pulled out of the recess 14. Therefore, the connection is easily released, which is extremely convenient when the wiring board 1 is detached from an electronic device or the like.

FIG. 5 shows a wiring pattern connection structure of a wiring board according to a second embodiment. This is to connect the wiring pattern 2 of the wiring board 1 using a detachable connector 10. The wiring board 1 is formed by laminating a resin or the like, and has a plurality (three in the embodiment) of a pair of wiring patterns 2 which are connected to each other. Among the sets of wiring patterns 2, in the center wiring pattern 2, one connection termination 3 is provided on the surface 1 a of the edge 4 of the wiring board 1, and the other connection termination 3 is provided on the end of the wiring board 1. It is provided at a position symmetrical to the back surface 1b and the front surface 1a of the edge portion 4. In the set of wiring patterns 2 on the left and right of the set of wiring patterns 2 at the center, the connection terminations 3 are arranged in line on the surface 1 a of the edge 4 of the wiring board 1.

The connector 10 has a plurality of rows of conductive wires 11 for short-circuiting connection ends 3 of a pair of wiring patterns 2 connected to each other, and a holding member made of insulating resin for holding the plurality of conductive wires 11. And a block 12. The conductive lines 11 for short-circuiting the central wiring pattern 2 are formed in a substantially U-shape up and down, and the conductive lines 11 for short-circuiting the pair of wiring patterns 2 on the left and right of the set of central wiring patterns 2.
Are formed substantially U-shaped in the plane direction of the substrate. The holding block 12 is molded into a substantially rectangular parallelepiped shape, and the bent portion 11a side of the conductive wire 11 is buried integrally at the time of molding. Further, in this connection structure, the positioning means 13, the first locking means 20, and the second locking means 25
Is formed in the same manner as in the first embodiment. Therefore, the second embodiment has the same operation and effect as the first embodiment.

In the above embodiment, the conductive wire 11
Although the contact portion 11b is exposed, the contact portion 11b is not limited to this. For example, as shown in FIG. I can do it. In addition, the number of the wiring patterns 2 and the number of the conductive lines 11 are not limited to those described above, and may be provided as appropriate. Also, the way of wiring of the set of wiring patterns 2 that are connected to each other may be appropriately changed, such as being provided on the front and back of the wiring board 1 or provided on one of the surfaces. Further, the number of wiring patterns 2 connected to each other is not limited to the above-mentioned pair, but may be three or more.

[0016]

As described above, according to the wiring pattern connection structure for a wiring board of the present invention, the positioning means can move the connection termination of the wiring pattern in the row direction at the required connection position of the connector. Since the regulation is performed, the contact between the connection end of the wiring pattern and the corresponding conductive wire does not shift in the connection state, and so-called pitch shift does not occur.
Connection can be ensured. In addition, since there is no contact shift, it is not necessary to move the connector one by one to perform fine adjustment and position alignment, thereby facilitating connection work and improving work efficiency.

In the case where the positioning means is constituted by a recess which is recessed at the edge of the wiring board and into which the holding block of the connector is removably fitted, a simple structure simply forming the recess is provided. Therefore, the manufacturing cost can be reduced and mass production can be performed. Further, in the case where the connector is provided with a locking means for restricting the movement of the connection end of the wiring pattern in a direction orthogonal to the row direction at the required connection position of the conductive wire, the movement of the connector is limited to a direction other than the row direction of the connection end. Therefore, the connector can be reliably held, the situation in which the connector is easily disconnected can be prevented, and the connection state can be maintained without welding as in the related art.

In particular, when the locking means is provided with an engaging projection and an engaging recess, the locking can be performed with a simple structure, so that the manufacturing cost can be reduced. Furthermore, when the locking means is provided with a pair of projecting pieces projecting from the holding block and holding the wiring board, the load on the conductive wire can be reduced, and the connector can be more securely held. As a result, the connection state can be reliably maintained without welding as in the related art.
