[0003]

[Problems to be solved by the device]

 However, in the case shown in FIGS. 3 (a) and 3 (b), the connection strength can be increased by engaging the connection fittings 2a and 2b with each other, but the connection fittings 2a and 2b are different parts. Attention must be paid to the attachment of 2b to the connectors 1 and 1, the number of parts must be increased, and measures must be taken on the connector 1 and 1 side to enhance the attachment strength of the connecting fittings 2a and 2b to the connectors 1 and 1. However, there is a problem that the configurations of the connectors 1 and 1 are complicated. In addition, in the structure shown in FIGS. 4 (a) and 4 (b), the connection fittings 2c, 2c can be formed in the same shape, but the connection fittings 2c, 2c are inserted and joined within the plate thickness range of the connection fittings 2c, 2c. However, there was a problem that the connection strength was reduced due to variations in plate thickness and mounting positions, making it difficult to sufficiently increase the connection strength.

The present invention is intended to solve such a problem, and an object thereof is to provide a connector connecting structure capable of achieving sufficient connection strength with connection fittings made of the same component. There is

[0005]

[Means for Solving the Problems]

 According to the present invention, an engaging hole 4 is formed in a central piece 3 on one side in the longitudinal direction of a U-shaped connecting fitting 2, and a leg piece on the other side in the longitudinal direction of the connecting fitting 2. A part of 5 is erected substantially parallel to the central piece 3 to form an upright connecting piece 6, and an engaging convex portion 7 is formed at the tip of this upright connecting piece 6 so as to face each other and be electrically connected. The above-mentioned U-shaped connecting fitting 2 is attached to the ends of the connectors 1 and 1 so as to be held, and the engaging projection 7 of the upright connecting piece 6 of the connecting fitting 2 of one connector 1 is attached to the other connector 1. It is characterized in that the connectors 1, 1 which are engaged with the engaging holes 4 of the central piece 3 of the connecting fitting 2 and are opposed to each other are connected.

[0006]

[Action]

 As described above, the engaging hole 4 is formed in the central piece 3 on one side in the length direction of the U-shaped connecting fitting 2, and the leg piece on the other side in the length direction of the connecting fitting 2 is formed. One part 5 is erected substantially parallel to the central piece 3 to form an upright connecting piece 6, and an engaging convex portion 7 is formed at the tip of this upright connecting piece 6 so as to face each other and be electrically connected. The U-shaped connecting fitting 2 is attached to the ends of the connectors 1 and 1 so as to be held, and the engaging projections 7 of the upright connecting pieces 6 of the connecting fitting 2 of one connector 1 are connected to the other connector 1. By engaging the engaging hole 4 of the central piece 3 of the metal fitting 2, that is, the connecting metal fitting 2 is formed in a U shape and held by the connector 1, and the mounting strength of the connecting metal fitting 2 to the connector 1 is increased. While making the shape of the connecting metal fitting 2 the same, the engaging projection 7 of the standing connecting piece 6 is By engaging the engaging hole 4, the connection strength is obtained by a sufficient.

[0007]

【Example】

 The connection fitting 2 is formed by bending a metal plate into a U shape. An engagement hole 4 is formed in a central piece 3 on one side in the lengthwise direction of the connection fitting 2. A part of the leg piece 5 on the other side in the length direction of the connecting fitting 2 is erected substantially parallel to the central piece 3 to form an upright connecting piece 6. An engaging projection 7 is formed at the tip of the standing connection piece 6. The connection fitting 2 is attached to the end of the connector 1. In such a case, the surface 5a of the leg piece 5 of the connection fitting 2 is flush with the soldering surface of the connector 1 to the printed wiring board 8, and the surface 5a of the leg piece 5 is soldered to the printed wiring board 8. Thus, the strength of attachment of the connector 1 to the printed wiring board 8 is increased to prevent the connector 1 from being peeled off from the printed wiring board 8.

Then, the connectors 1 and 1 mounted on the printed wiring board 8 are opposed to each other, and the engaging protrusions 7 of the upright connection pieces 6 of the connection fittings 2 at the ends thereof are connected to the connection metal of the other connector 1. The connectors 1, 1 facing each other are connected by engaging with the engaging holes 4 of the central piece 3 of the tool 2. In such a case, the connectors 1 and 1 are electrically connected. Then, the grounding function between the printed wiring boards 8 is achieved by connecting the connecting fittings 2 and 2. Further, when the connecting fittings 2 and 2 are inserted and removed, the connecting fitting 2 prevents the soldering of the connector 1 from peeling off.

In this way, the connecting fitting 2 is formed in a U-shape so that it can be held by the connector 1, so that the attachment strength of the connecting tool 2 to the connector 1 is sufficient, and the connection is made. The connecting metal fitting 2 has the same shape to reduce the number of parts. Further, by engaging the engaging convex portion 7 of the standing connection piece 6 with the engaging hole 4 of the central piece 3, the connection strength is also sufficient.

[Effect of the device]

 According to the present invention, as described above, the engaging hole is formed in the central piece on one side in the length direction of the U-shaped connecting fitting, and the engaging hole is formed on the other side in the length direction of the connecting fitting. A part of the leg piece is erected substantially parallel to the center piece to form a standing connection piece, and an engaging protrusion is formed at the tip of this standing connection piece. The above-mentioned U-shaped connecting metal fitting is held and attached to the part, and the engaging convex portion of the upright connecting piece of the connecting metal fitting of one connector engages with the engaging hole of the central piece of the connecting metal fitting of the other connector. That is, by forming the connecting metal fitting in a U-shape so that it can be held by the connector, the connecting metal fitting can have the same shape while ensuring sufficient attachment strength of the connecting metal fitting to the connector. The connection strength of the connector can also be increased by engaging the engagement protrusion of the stand-up connection piece with the engagement hole of the center piece. There is an advantage that it can be in the minute things.
