Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for a flexible printed circuit board (flexible printed circuit board).

[0002]

2. Description of the Related Art FIGS. 10 and 11 show a conventional flexible printed circuit board connector. 10 to 11, reference numeral 1 denotes a connector main body having an opening on one side, and a plurality of contacts 2 are accommodated in the connector main body 1. 2a
Is the contact 2 protruding outside from the bottom surface of the connector body 1.
The lead portion 2a is soldered to a printed circuit board or the like. Reference numeral 3 denotes a lock plate slidably held in the connector body 1, and side pieces 4 integrally formed on both sides of the lock plate 3 are inserted into the holes formed in the connector body 1 to form a connector. It is slidably held by the main body 1. Reference numeral 5 denotes a claw portion formed outward at the tip of the side piece 4 of the lock plate 3, and the claw portion 5 is inserted into the groove 6 of the connector body 1 to prevent the claw portion from coming off.
Reference numeral 7 is a guide piece integrally formed at both ends of the lock plate 3. Reference numeral 8 denotes a flexible printed circuit board. The flexible printed circuit board 8 has a structure in which a plurality of conductor foils 9 are sandwiched between insulating sheets 10. Exposed. As shown by the broken line in FIG. 11, the flexible printed board 8 is bent at a substantially right angle in the vicinity of the tip portion.

In FIG. 10, when the flexible printed circuit board 8 is inserted between the upper surface of the lock plate 3 and the connector body 1 while the lock plate 3 is pulled toward you, the tip of the flexible printed circuit board 8 is connected to the connector. The conductor foils 9 of the flexible printed circuit board 8 which are in contact with the bottom surface of the flexible printed circuit board 8 and which are exposed at the tips of the flexible printed circuit boards 8 are in contact with the contact points 2 of the connector body 1 to form the conductive foils of the flexible printed circuit board 8. Reference numeral 9 is for establishing electrical connection with each contact 2 in the connector body 1. When the lock plate 3 is pushed in in this state, the tip of the flexible printed circuit board 8 is clamped between the lock plate 3 and the inner wall of the connector body 1, and the flexible printed circuit board 8 is locked to be in a retaining state. .

[0004]

However, in the above-described conventional example, when the flexible printed circuit board 8 connected to the connector body 1 is bent near the connector body 1, the flexible printed circuit board 8 is previously inserted in the connector body 1 in advance. Flexible printed circuit board 8
Had to be bent. Further, since the flexible printed circuit board 8 is bent in advance, the bent portion of the flexible printed circuit board 8 becomes weak and durability is reduced.

The present invention solves the above-mentioned problems of the prior art. A flexible printed circuit board inserted in a connector body is placed near the connector body without bending the flexible printed circuit board in advance. A flexible printed circuit board connector that can be led out at a predetermined angle.

[0006]

In order to achieve the above object, the present invention provides a connector body in which contacts are housed, a lock plate slidably supported in an opening of the connector body, and the connector. And a guide member formed with a guide piece part which is inserted from the opening of the main body and regulates the pulling-out direction of the flexible printed circuit board which comes into contact with the contact. The guide member is provided on both the connector main body and the lock plate. Alternatively, it is characterized in that it can be locked to either one of them.

[0007]

The present invention has the above-mentioned structure, and the guide piece portion of the guide member locked to the connector body and / or the lock plate can regulate the pulling direction of the flexible printed circuit board. is there.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIG. 1 to 3, the same components as those in FIGS. 10 and 11 are designated by the same reference numerals. 1 to 3, 11 is a guide member for guiding the flexible printed circuit board 8 in a predetermined direction.
1 is formed on a flat plate portion 13 in which a hole 12 into which the flexible printed circuit board 8 is inserted, a guide piece portion 14 integrally formed at one end of the flat plate portion 13, and a lower surface of one end of the flat plate portion 13. The locking claw 15 and the locking piece 16 formed on the lower surface of the other end of the flat plate portion 13.

As shown in FIGS. 1 to 3, after inserting the tip of the flexible printed board 8 into the hole 12 of the guide member 11, the flexible printed board 8 is attached to the upper surface of the lock plate 3 and the connector body 1. When inserted between the flexible printed circuit board 8 and the bottom surface of the connector body 1, the flexible printed circuit board 8 comes into contact with the bottom surface of the flexible printed circuit board 8. The conductor foils 9 of the flexible printed board 8 are brought into conduction with the contacts 2 in the connector body 1 by contacting the contacts 2. When the lock plate 3 is pushed in in this state, the tip of the flexible printed board 8 is sandwiched between the lock plate 3 and the inner wall of the connector body 1, and the flexible printed board 8 is held.
Is locked and locked out.

Thereafter, the guide member 11 is pressed against the upper surface of the connector body 1 as shown in FIG. In this case, the locking claws 15 of the guide member 11 are the recesses 1 on the back of the connector body 1.
The lock piece 16 of the guide member 11 is locked to the corner of the guide piece 7 of the lock plate 3. In this way, the guide member 11 is locked to the upper surface of the connector body 1, and the flexible printed board 8 inserted in the hole 12 is guided by the guide piece portion 14 of the guide member 11 and led out in a predetermined direction. .

As described above, according to the above-described embodiment, as shown in FIG. 3, the locking claw 15 of the guide member 11 is engaged with the recess 1A in the back portion of the connector body 1, and the locking piece 16 is formed. By engaging with the corner of the guide piece 7 of the lock plate 3, the guide piece portion 14 of the guide member 11 can regulate the pull-out direction of the flexible printed circuit board.

4 to 9 show a second embodiment of the present invention. The structure of the guide member of this embodiment is different from that of the first embodiment. The guide member 17 of this embodiment has a structure in which locking pieces 19 are integrally formed at both ends of the guide piece portion 18, and locking claws 20 are formed at the free ends of the locking pieces 19. As shown in FIGS. 4 and 5, the flexible printed circuit board 8 has the guide piece 1
The guide member 17 is moved from the lock plate 3 side so as to be in contact with the upper surface side of the connector 8 so that the locking claw 20 moves.
It is to be locked on the back of.

In the above embodiment, the guide members 11, 1 are used.
7 is locked to the connector body 1 and the lock plate 3,
The guide members 11 and 17 may be locked only to the connector body 1 or only the lock plate 3.

[0014]

As is apparent from the above-described embodiment, the present invention allows the connector main body to be simply locked by the guide member having the guide piece portion for restricting the pull-out direction of the flexible printed circuit board. It has the advantage that the flexible printed circuit board inserted in the can be pulled out in a predetermined direction, and since it is not necessary to bend the flexible printed circuit board in advance, the durability of the flexible printed circuit board can be improved. It is a thing.
