Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector device for connecting flexible printed circuit boards.

Here, the flexible printed circuit board refers to a member to be connected that has conductive strips arranged in parallel at regular intervals on the surface of a flat thin plate. Various proposals have been made to increase the pressure contact force at the connecting portion, and to securely hold the printed circuit board between the housing and the slide plate into which the printed circuit board is inserted.

All of the objects of implementation of the present invention are small, and all of them are 201
nx or less, it is difficult to ensure a secure connection and increase the pressure contact force.The purpose of the present invention is to connect this type of printed circuit board reliably and with a strong pressure contact force. The purpose is to make the configuration simple and easy to implement.

The configuration of the device of the present invention will be explained with reference to the drawings. As shown in FIGS. 1 to 3, a housing A and a slide plate B are shown.
Both are made by molding with a suitable synthetic resin,
The two are connected by an engaging portion 1 that is either separated as in the embodiment shown in FIG. 1 or connected at a portion where insertion is not hindered as in the embodiments shown in FIGS. 2 and 3.

In addition to being connected as shown in the drawings, the engaging portions 1 can also be detachably connected, for example, by means of a hinge mechanism (not shown), such as the connecting portion shown in FIG. 3, so that they can be separated at will.

There is an opening 2 inside the unong A that leads from the front to the rear, and a printed circuit board C is inserted into this opening 2, and it is suitable for mounting a metal connector 9 that matches the number of poles. The number h3 is formed in the isomorphic horizontal direction.

The sliding plate B that is inserted into the housing A that has been cut out is formed with an actuating piece 4 that is inserted into the opening 2 of the housing song A and fitted into each groove 3 of the bracket, and the lower surface of each actuating piece 4 has an inclined part. 5 and a thick part 6, a hooking part 7 is projected from the upper surface and positioned so as to be able to be hooked to a hooking receiving part 8 provided on the upper surface of the opening 2 of the housing A.

A lower contact piece 10 is joined to the bottom of the matching groove 3 of the front housing A, and a metal connector 9 with an upper contact piece 11 attached thereon is attached, and a metal connector 9 is mounted on the front upper surface of the lower contact piece 10. The convex part 12 is provided with an upright part 13 on the next upper surface at an appropriate interval, a downwardly curved part 14 is formed in front of the upper contact piece 11, and a downwardly directed tip part 15 is formed inwardly.

The printed circuit board C to be inserted into the opening 2 of the housing A having the metal connector 9'z is mounted on a flexible thin flat plate surface at a constant distance, as shown in part in FIG. A thin electrically conductive piece C1 is provided in parallel, and is inserted between the upper and lower contact pieces 10.11 of the metal connector 9.
After inserting the operating piece 4 of the slide plate B into the opening 2 of the housing A,
This configuration connects the printed circuit board C and the printed circuit board C.

When doing this, as the lower surface inclined portion 5 of the actuating piece 4 of the slide plate B first presses down on the curved portion 14 of the upper contact piece 11, the downward tip portion 15 moves the conductive piece C of the contact board C.
1, slides on it while removing impurities on its surface, and stops when it hits the upright portion 13 of the lower contact piece 10,
As a result of sandwiching the printed circuit board C at two places, such as this part and the receiving convex part 12 where the curved part 14 contacts downward, the pressure contact is strong and reliable, and the effect of enhancing the connector function is enormous. .
