DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector provided with a conductive plate in which female and male terminals of different shapes to be fitted are of the same shape, and a conductive plate is used to electrically connect the terminals.

[0002]

2. Description of the Related Art Conventionally, as this kind, there is one as shown in FIG.

[0003] That is, as shown in FIG.
The female terminal piece 2 with the wire harness 2A crimped therein is inserted into the female housing 3. A retainer 7 is incorporated in the female housing 3. The retainer 7 is locked by a locking portion 10 provided on the female terminal piece 2, and a lance 8 provided inside the housing upper wall 11 is provided with a female terminal piece 2. And is double-locked.

Then, the male terminal piece 4 with the wire harness 4A crimped is inserted into the male housing 9, engaged with the retainer 71, fitted into the female terminal piece 2, and electrically connected to the connector 1. I have.

[0005]

However, the connector 1 shown in FIG.
Since the male terminal piece 4 is fitted into the female terminal piece 2 inserted therein, high processing accuracy is required and the cost is high. In addition, it is difficult to maintain the contact accuracy, and a contact failure occurs when subjected to an external force. Had the problem of being easy.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connector with a conductive plate which can reduce the cost without requiring high processing accuracy and hardly cause a contact failure even when an external force is applied.

[0007]

In order to achieve the above-mentioned object, according to the present invention, a belt-like body is provided so as to extend from one end and the other end of a rectangular plate to both sides. The band-shaped body provided at the one end is folded back at both ends thereof in a state having an elastic force to provide a folded portion, and further in a substantially U-shape such that the folded portion approaches from the center of the plate material. Forming a terminal piece having a bent U-shaped part,
The conductive end of the wire harness whose coating has been peeled off is sandwiched between the U-shaped portions of the terminal pieces, and the band-shaped body provided at the other end is bent inward to be crimped so as to surround the wire harness. Assembling the terminal strip and the wire harness to form a terminal, fitting each terminal to a terminal fitting portion of the upper and lower housing to form an upper and lower connector,
A conductive plate formed by integrally forming a plurality of plate-shaped conductive pins and a plate formed on a face plate having substantially the same size as the connector so that the conductive pins intersect at an appropriate interval. It is characterized in that it is assembled so as to be sandwiched by both upper and lower connectors, and is engaged via engagement means provided on the upper and lower connectors, so that the connectors are electrically connected by the conductive plate.

According to a second aspect of the present invention, in the connector with a conductive plate according to the first aspect, the engaging means has opposed standing walls extending along left and right side surfaces of the lower housing. A plate fitting groove is provided at the lower part of the standing wall to face the opening, and a hook is provided at the upper part of the standing wall so as to face the upper wall, and a convex engagement having curved surfaces on both left and right sides of the upper housing. A lock is provided, an engagement groove is provided at a position beyond the engagement lock, and as the upper and lower housings are assembled, the hook slides along a curved surface of the lock and, when the hook gets over the engagement lock, The standing wall is elastic so as to slide into the engaging groove.

According to a third aspect of the present invention, in the connector with a conductive plate according to the first aspect, both ends are formed in a projecting shape when viewed from the side, and a projection is formed on at least one side of the surface of the conductive pin. And the projection is fitted to the terminal piece.

[0010] Here, the term "providing a folded portion by folding back into a state having elasticity" means that if the bent portion is completely plastically deformed at the time of folding, the folded portion loses elasticity and fits into the folded portion. Since there is no longer any force for tightening the bent portion, the bent portion R is made to have an elasticity by increasing the bending R of the bent portion.

Here, the elastic standing wall is a structure in which, when the upper and lower housings are fitted, the hook as the engaging means must slide over the convex engaging lock. Since it is necessary to restore the original state after breaking over the engagement lock without being damaged by the amount of deformation at the time, engineering resin with high mechanical strength is used as the material, and the thin part is used as the shape. Provided,
It is designed to be easily deformed.
