Abstract

PROBLEM TO BE SOLVED: To mount a flexible printed wiring board inside a housing with a simple operation by stopping, between a slide and the housing, the slide in a position to be inclined obliquely upward relative to the housing. SOLUTION: When a slide 5 is forcibly rotated in the clockwise direction around an engaged second projection 11 from its stop position, the spherical projection 31 of a locking means 30 and a recessed part 32 formed in the bottom surface 6a of a guide groove 6 are fitted to and engaged with each other, thus the rotation of the slide 5 in the counterclockwise direction is prevented and it is positioned and locked in this position. Thus, the tip 5a of the slide 5 is raised obliquely upward so as to facilitate the insertion of a flexible printed wiring board and, since the slide 5 is positioned and locked in the inclined position by the locking means 30 when its inclined attitude is maintained, no external supports for the maintenance of this inclined attitude are necessary.

[0011]

According to the conventional connector 1 described above, as shown in FIG.
At the time of mounting, the distal end 5a of the slide 5 is lifted obliquely upward so as to facilitate the insertion operation, and the inclined posture is maintained. However, conventionally, in order to maintain the inclined posture, an external support, for example, an operator slide 5, the mounting operation of the FPC 2 is not only troublesome and troublesome, but also the support of the slide 5 for maintaining the inclined posture becomes a hindrance when inserting the FPC 2, and the mounting operation of the FPC 2 becomes difficult. There were difficulties.

An object of the present invention is to provide a flexible printed wiring board connector in which a flexible printed wiring board is mounted in a housing by a simple operation in view of the above-mentioned circumstances.

[0013]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a housing having a contact connected to a connection terminal of a flexible printed wiring board, and a housing slidably disposed horizontally with respect to the housing. And a slide that is rotatably supported so as to be inclined obliquely upward with respect to the housing after being slid out of the initial position and horizontally pulled out from the initial position when the flexible printed wiring board is mounted, After the flexible printed wiring board is inserted into the housing, the slide in the inclined posture is slid back to the horizontal initial position, whereby the connection terminal corresponding to the pressing piece formed on the slide corresponds to the connection terminal. In a connector for a flexible printed wiring board that is pressed against a contact,
A locking means is provided between the slide and the housing to stop the slide in an inclined position obliquely upward with respect to the housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the connector according to the present invention will be described in detail.

FIG. 1 is a conceptual perspective view showing a connector 20 for a flexible printed wiring board according to the present invention. In FIG. 1, the same parts as those in FIGS. 2 shows a state where the positioning is supported.

This flexible printed wiring board connector 2
0 (hereinafter simply referred to as a connector), a pair of slide legs 7 formed on both sides of the slide 5 and the housing 4
A lock for positioning and stopping the slide 5 in an inclined posture obliquely upward with respect to the housing 4 between the pair of guide grooves 6 formed on both sides of the housing 4 and having a U-shaped cross section for slidably guiding the slide legs 7. Means 30 are interposed.

As shown in FIG. 2 which is an enlarged sectional view taken along the line CC in FIG. 1, the locking means 30 includes a spherical projection 31 protruding from the inclined surface 7b below the tip 7a of the slide leg 7 and a housing tip 4a side. Formed on the bottom surface 6a of the guide groove 6 of
And a concave portion 32 in which the spherical projection 31 is fitted and supported.

Next, the operation of the locking means 30 will be described.

From the initial position of the slide 5 shown in FIG. 1, that is, the horizontal position of the slide 5 with respect to the housing 4, the slide 5 is pulled out along the guide groove 6 toward the housing tip 4a as shown in the perspective view of FIG.

Then, FIG. 4 shown in the DD enlarged sectional view of FIG.
The engaging claw 9 formed at the tip 7a of the guide leg 7 as shown in FIG.
And the first projection 10 for positioning and supporting the guide leg 7 at the initial position in FIG. 1 is released.
Is engaged with the second projection 11 which stops the slide 5 at the position where the slide 5 is slid horizontally and pulled out, and stops at that position.

From the stop position of the slide 5 shown in FIG. 4, when the slide 5 is forcibly rotated clockwise around the second projection 11 which engages the slide 5, the perspective view of FIG. As shown in FIG.
The spherical projection 31 and the concave portion 32 formed on the bottom surface 6a of the guide groove 6 are fitted and engaged with each other, thereby preventing the slide 5 from rotating counterclockwise and being locked in position. Become.

Therefore, as shown in FIG.
When the tip 5a of the slide 5 is lifted obliquely upward so as to easily insert the slide 5 and the inclined position is maintained, the slide 5 is positioned and locked at the inclined position by the lock means 30, so that the inclined position is maintained. No external support is required.

After the FPC 2 is inserted into the housing 4 as shown by the arrow A in the state shown in FIG. 5, the slide 5 is forcibly rotated counterclockwise to lock the lock means 30.
The lock of the slide 5 is released, and thereafter, the same operation as in FIGS. 9 to 11 is performed, so that the electrical connection between each connection terminal of the FPC 2 and each corresponding contact 3 is established.

When the electrical connection between each connection terminal of the FPC 2 and each corresponding contact 3 is released, an operation reverse to the above-mentioned operation may be performed.

In the above embodiment, the projection 31 is formed in a spherical shape. However, the projection 31 may have, for example, a triangular cross section, and is not limited to this shape.

[0026]

As described above, according to the connector for a flexible printed wiring board of the present invention, when the slide is inclined so that the flexible printed wiring board can be easily inserted, the inclined posture is supported by the external means by the locking means. The flexible printed wiring board can be easily attached to the connector.When the flexible printed wiring board is automatically assembled to the connector by another device, the inclination of the slide is maintained. Since no supporting member is required at all, the assembling steps can be reduced and the manufacturing efficiency can be greatly improved.
