Abstract

PROBLEM TO BE SOLVED: To reduce cost and outside dimension by changing the state that prevents a flat wire from slipping off by bringing a flexible piece into press contact with a terminal part of the inserted flat wire to the state that allows the flat wire to be inserted and extracted by separating the flexible piece from the inserted flat wire terminal part and vice versa in response to a mutual sliding motion between a case and a contact. SOLUTION: When a flat wire 3 is installed, a case 4 is slid toward the free end side of both flexible pieces 51, 52 of a contact 5. The front upper corner part of a swollen part 43 of the case 4 comes into contact with and forcibly tilts upward an intermediate part of a first flexible piece 51 of a contact 5 so that the clearance between both the flexible pieces 51, 52 is made larger than the thickness (t) of the flat wire 3, as shown by (h2 ). The flat wire 3 is inserted until it is abutted against the swelled part 43. Then, the case 4 is slid backward so as to prevent the flat wire from slipping off. When the flat wire 3 is extracted, the case 4 is slid forward so as to bring it into a state sown in Fig. (c) and thereby, the flat wire 3 can be extracted with no resistance.

The connector 1 has a structure in which a large number of contacts 5 arranged side by side at a predetermined pitch with respect to a case 4 are slidable by a required stroke.

The case 4 is made of a molded product using an insulating material such as a synthetic resin, and has a rectangular top plate portion 41 and two
Side plate portions 42, 42 extending downward on the two short sides, and a swelling portion 43 swelling downward is provided on the inner surface of the top plate portion 41 in the rear half region in the short direction. A space 44 into which the flat electric wire 3 is inserted is provided in the front half of the inner surface of the top plate portion 41 in the short direction on the inner surface of the top plate portion 41. At several locations in the longitudinal direction of the bulging portion 43 at equal intervals, through holes 45 penetrating in the short direction of the top plate portion 41 are provided.

The contact 5 is formed by bending a belt-shaped body made of a conductive member into a U-shape, and has two long and short flexible pieces 51 and 52 parallel to each other. This contact 5 is a short first flexible piece 5 in its own natural state.
1 is set so as to be close to the long second flexible piece 52, and the distance between the two flexible pieces 51, 52 is set as shown in FIG.
It is smaller than the thickness t of the end portion of the flat electrical wire 3 as shown in h ₁ of (a).

The first flexible piece 51 of each contact 5 is inserted into the plurality of through holes 45 of the case 4 so that the second flexible piece 52 is completely exposed on the lower surface of the case 4. Assembled. In this state, the first and second flexible pieces 51 and 52 sandwich the bulging portion 43 from above and below, and cannot be easily removed unless the contact 5 is pulled out with a force larger than required. ing.

As shown in FIG. 1, such a connector 1 is mounted horizontally on the surface of a printed circuit board 2. That is, with respect to the electrode pad portion (not shown) of the printed wiring (not shown) formed on the surface of the printed board 2
The free ends of the second flexible pieces 52 of the contacts 5 of the connector 1 are joined by soldering, whereby the connector 1 is fixed to the printed circuit board 2 and the case 4
Most of the second flexible pieces 52 exposed from the outside are hidden from the outside.

When the connector 1 is mounted on the printed circuit board 2 as described above, the case 4 can slide with respect to the contacts 5 fixed to the printed circuit board 2. Here, for example, as shown in FIG. 1B, if the case 4 is slid toward the free ends of the two flexible pieces 51 and 52 of the contact 5, the flat wire 3 is inserted into and removed from the connector 1 without resistance.

It is supposed to be.

Next, the flat wire 3 for the connector 1
Will be described.

First, when attaching the flat wire 3,
As shown in FIG. 1B, the case 4 is slid forward from the state shown in FIG. 1A to the free ends of the two flexible pieces 51 and 52 of the contact 5 as shown in FIG. As a result, the front upper corner of the bulging portion 43 of the case 4 comes into contact with the middle part of the first flexible piece 51 of the contact 5, and the first flexible piece 51 is forcibly lifted and tilted. distance between the flexible piece 51 is larger than the thickness t of the flat wire 3 as indicated by h ₂ in FIG. 1 (b). Therefore, as shown in FIG. 1C, the flat electric wire 3 is inserted from between the two flexible pieces 51 and 52 until it hits the bulging portion 43. At this time, since the flat wire 3 can be inserted without any resistance, it can be said that it has a ZIF structure.

Thereafter, the state shown in FIG.
The case 4 is slid rearward, that is, toward the connecting portion of the two flexible pieces 51 and 52 of the contact 5 to the state shown in FIG.
As a result, the front upper corner of the bulging portion 43 of the case 4 is separated from the middle portion of the first flexible piece 51 of the contact 5, and the first flexible piece 51 is brought into a natural state by its own elastic restoring force. It will return and fall. As a result, the first flexible piece 51 elastically urges the flat wire 3 downward and presses it against the second flexible piece 52, so that the flat wire 3 is held by the upper and lower flexible pieces 51, 52. Because of being pinched, escape is prevented. In this state, the flat wire 3
