BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector device which is an electrical component, and more particularly to a connector device which presses against a contact utilizing a spring property of a cantilever type socket contact. .

[0002]

2. Description of the Related Art A conventional connector device will be described with reference to FIG. FIG. 1 shows a state in which a socket 1 and a plug 2 mounted on a substrate are fitted. In the resin mold body 3 of the socket 1, walls 4, 4 are erected on the left and right sides in the figure, and holes 5, 5 penetrating to the bottom surface along the outer surfaces of the walls 4, 4 are formed. Socket contacts 6, 6 made of a leaf spring material are press-fitted into the holes 5, 5, and one end thereof is inverted at the upper ends of the walls 4, 4 and faces the bottom between the walls 4, 4.

The plug 2 is substantially m-shaped in cross section, and male contacts 8, 8 corresponding to the socket contacts 6, 6 are fixed to both left and right surfaces of the central projection 7, respectively. As shown in the figure, when the plug 2 is fitted into the socket 1, the male contacts 8, 8 come into contact with the socket contacts 6, 6, and the socket contacts 6, 6 elastically contact the male contacts 8, 8 by the spring property. Connected.

The contact pressure between the socket contacts 6, 6 and the male contacts 8, 8 varies depending on the processing accuracy of the socket contacts 6, 6, and the wall portions 4, 4 which are cantilevered support portions.
And socket contacts 6 and 6
As shown in the left side of FIG.
With the fulcrum as a fulcrum, the socket contact 6 may bend to the rear side, and the contact pressure to the male contact 8 may decrease.

[0005]

The connector device of the type in which the above-mentioned cantilever type socket contact and the male contact are pressed into contact with each other may cause a contact failure due to a reduction in the contact pressure due to the processing accuracy and assembly accuracy of the socket contact. is there. Therefore, there is a problem that high precision is required for processing and assembly, and it is difficult to reduce the manufacturing cost.

Accordingly, the technical problems to be solved in order to reduce the burden of precision control in the manufacturing process, eliminate the possibility of occurrence of contact failure, and reduce the cost and improve the reliability by improving the yield. Has occurred. The purpose of the present invention is to solve this problem.
