DESCRIPTION OF THE PREFERRED EMBODIMENTS A surface contact type connector according to the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a first connector attached to a door panel A side. The first connector is provided with a side plate having a guide slot 11 parallel to the bottom surface on a base 10 having right and left sides opposed to each other. A terminal frame 13 is provided slidably on which a pin 12 penetrating and protruding outward is provided symmetrically on both left and right sides, and is fixed to the terminal of the electric wire 14 on the terminal frame 13. A plurality of rectangular flat terminals 15 are arranged and fixed in parallel to the bottom surface of the base 10, that is, the surface of the terminal frame 13. Therefore, the flat terminal 15 can freely move back and forth within the range limited by the elongated hole 11 in parallel with the bottom of the base 10 together with the end of the electric wire 14.

Reference numeral 2 denotes a second connector mounted on the door trim B side. When the second connector is fitted to the first connector 1, a side plate having a pin guide groove 21 for fitting and guiding the pin 12 is provided. A socket body 20 is provided on the left and right sides to face each other. A plurality of contact terminals 24 made of elastic metal pieces are provided on the upper surface of the socket body 20.
Are protruded in an arrangement corresponding to the flat terminal 15 described above. And this pin guide groove 21 is the first connector 1
Are inserted into the socket-shaped second connector 2 from a direction perpendicular to the bottom surface with the respective bottom surfaces kept parallel, the flat terminal 15 first faces the contact terminal 24 projecting from the bottom surface. Then, the pin 12 is formed in such a shape that it can be guided while contacting it while being guided obliquely to the bottom surface, and finally press the contact terminal 24 vertically again.

At the bottom of the pin guide groove 21, that is, at the terminal end, a pin locking arm 22 is provided so as to protrude inward of the pin guide groove 21.
Is configured to prevent the first connector 1 inserted into the second connector 2 from dropping off by engaging with the pin locking arm 22. The tip of the pin 12 that engages with the pin locking arm 22 is formed in a shape suitable for achieving reliable locking. Further, a locking projection 23 is provided on the edge of the opening of the socket body 20 to prevent the tip end of the inserted terminal frame 13 from dropping off the socket body 20.

The surface contact type connector of the present invention is mounted so as to face the surface of the door panel A and the surface of the door trim B, respectively. The mounting position of the first connector 1 and the second connector 2 is determined by the fitting of the door trim B. It is necessary to determine in advance in consideration of the joint position. For example, as shown in FIG. 3, the door trim B can be mounted and fixed to the door panel A by inserting a clamp 3 protruding from the surface of the door trim B into a mounting hole 4 provided on the surface of the door panel A.
