FIG. 1 is a perspective view showing an embodiment of a connector according to the present invention, FIG. 2 is a vertical sectional view taken along the line II-II in FIG.
FIG. 3 is a vertical sectional view taken along the line III-III in FIG. 1. However, the same parts as those in FIG. 6 are denoted by the same reference numerals, and redundant description is omitted.

The connector 10 according to the present invention is a housing 1 having a lower surface 12a mounted on a printed wiring board 52.
2, a contact piece provided on the side surface 12b of the housing 12 and for inserting a flexible printed wiring board or the like 56, and a contact piece for making electrical contact with the conductive portion 62 of the flexible printed wiring board 56 inserted from the insertion port 14. 1
6 is provided. Then, the contact piece 16 is pressed to increase the contact force between the contact piece 16 and the conductive portion 62.
An id plate 18 is provided on the upper surface 12 c of the housing 12. The slide plate 18 slides the printed wiring board 52 almost in parallel, so that the contact piece 16
Is pressed. Further, a locking member 20 for holding the pressed state of the slide plate 18 is provided.

The contact piece 16 is made of a metal having excellent conductivity and elasticity, such as phosphor bronze or brass, which is used for a general stationary contact, and is electrically connected to a wiring (not shown) on the printed wiring board 52. .

The slide plate 18 is fitted into an opening window 12d on the upper surface 12c of the housing 12. Open window 12
A groove 12e for smoothing the sliding of the slide plate 18 is formed below d. The depth of the groove 12e is substantially equal to the thickness t1 of the slide plate 18. Open window 1
The relationship between the width W1 of 2d and the width W3 of the slide plate 18 is such that the slide plate 18 does not come off the opening window 12d.
<W3. On the side of the insertion port 14 of the slide plate 18, the finger 64 protrudes upward so as to be easily caught.
A ridge 181 is formed.

The locking member 20 includes a locking plate 201 inserted below the slide plate 18 (toward the printed wiring board 52).
, A spring 202 for pressing the locking plate 201 upward (toward the slide plate 18), and a housing hole 203 for housing the spring 202. The slide plate 18 slides,
When the locking plate 201 comes off from above, the pressing force of the spring 202 causes the locking plate 201 to abut against the opening window 12d. At this time, the width W2 of the locking plate 201 is set to W2> W1 so that the locking plate 201 does not protrude from the opening window 12d. The thickness t2 of the locking plate 201 is set to be t2> t1 so as not to enter the groove 12e.

The housing 12, the slide plate 18, the locking plate 201, and the like are made of synthetic resin having excellent insulation properties. In this case, since the restoring force of the contact piece 16 is applied, the material of the slide plate 18 and the groove 12e is preferably hard and hard to bend, such as PPS (polyphenylene sulfide).

FIGS. 4 and 5 are longitudinal sectional views showing the operation of the connector 10. FIG. Hereinafter, the operation of the connector 10 will be described with reference to FIGS.

The flexible printed wiring board 56 is inserted into the insertion opening 14 of the housing 12 (FIGS. 1 to 3). Subsequently, when the finger 64 is hung on the ridge 181 and pressed in the direction of the arrow 30, the slide plate 18 slides smoothly along the groove 12e (FIG. 4). Since the contact piece 16 protrudes on the movement locus of the slide plate 18, the slide plate 18 presses the contact piece 16 as the slide plate 18 slides. Thereby, the contact piece 16 is deformed and pressed against the conductive part 62, so that good electrical contact between the contact piece 16 and the conductive part 62 is obtained (FIG. 5). At this time, when the slide plate 18 comes to a position where it comes into contact with the housing 12, the slide plate 18 comes off from above the locking plate 201, so that the locking plate 201 protrudes and closes the groove 12e. Therefore, the slide plate 18 is held at that position, and it is possible to prevent the slide plate 18 from shifting due to an external force or the like and releasing the contact between the contact piece 16 and the conductive portion 62.

In this state, to remove the flexible printed wiring board 56 from the insertion port 14, the spring 202
The locking plate 201 is pushed by the finger 64 in the direction of the arrow 32 against the restoring force of. Then, the slide plate 18 can slide in the groove 12e, and the slide plate 18 can be returned to the state shown in FIG. In this state, the contact piece 16 and the conductive portion 62
Are not in contact with each other, so that the flexible printed wiring board 56 can be easily pulled out of the insertion opening 14.

As described above, since the operation required for inserting and removing the flexible printed wiring board 56 can be performed within the area occupied by the connector 10, the space S (FIG. 6) conventionally required can be eliminated.

[0021] The present invention is, of course, have name limited to the above embodiments.

[0022]

According to the connector of the present invention, by sliding the slide plate on the upper surface of the housing,
Since the contact force between the contact piece of the connector and the conductive portion of the flexible printed wiring board is increased, the space required for insertion and removal of the flexible printed wiring board other than the area occupied by the printed wiring board can be eliminated. Therefore, high-density mounting of products can be achieved.

In addition, the contact force between the contact piece and the conductive portion can be increased by a simple operation of simply pressing the slide plate with a finger.

[0024] In addition to this, it is inserted under the slide plate.
Locking plate, a spring that presses the locking plate upward, and a spring
Since the locking member composed of the receiving hole to accommodate is provided,
Make sure that the pressed state of the slide plate is released by external force, etc.
To improve the stability of electrical contact between the contact piece and the conductive part.
I can do it. In addition, the locking plate is pressed with a finger against the restoring force of the spring.
By simply pressing down, the slide plate slides above the locking plate.
Can be loaded, so flexible print distribution from the insertion slot is possible.
The wire plate can be easily pulled out.
