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 connector for a flexible printed circuit board. 10 to 11, reference numeral 1 denotes a connector main body having an open surface, and a plurality of contacts 2 are housed in the connector main body 1. 2a
Is the contact 2 protruding outside from the bottom surface of the connector body 1.
The lead 2a is soldered to a printed circuit board or the like. Reference numeral 3 denotes a lock plate slidably held by the connector main body 1. Side pieces 4 integrally formed on both sides of the lock plate 3 are inserted into holes formed in the connector main body 1 so that a connector is provided. The main body 1 is slidably held. Reference numeral 5 denotes a claw portion formed outward at the tip of the side piece 4 of the lock plate 3. The claw portion 5 is inserted into the groove 6 of the connector body 1 and is prevented from coming off.
Reference numeral 7 denotes 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 conductive foils 9 are sandwiched between insulating sheets 10. It is exposed. As shown by the broken line in FIG. 11, the flexible printed circuit board 8 is bent substantially at a right angle near the front end.

In FIG. 10, when the flexible printed circuit board 8 is inserted between the upper surface of the lock plate 3 and the connector main body 1 with the lock plate 3 pulled toward the user, the front end of the flexible printed circuit board 8 becomes the connector. Each of the conductive foils 9 contacting the bottom surface in the main body 1 and exposing the front end of the flexible printed circuit board 8 contacts each contact 2 in the connector main body 1 to form each conductive foil 9 on the flexible printed circuit board 8. Reference numeral 9 denotes a state in which each of the contacts 2 in the connector main body 1 is in a conductive state. When the lock plate 3 is pressed in this state, the front end of the flexible printed circuit board 8 is sandwiched between the lock plate 3 and the inner wall of the connector main body 1, and the flexible printed circuit board 8 is locked to prevent the flexible printed circuit board 8 from coming off. .

[0004]

However, in the above conventional example, when the flexible printed circuit board 8 connected to the connector main body 1 is bent in the vicinity of the connector main body 1, before the flexible printed circuit board 8 is inserted into the connector main body 1, 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 is weakened, and the durability is reduced.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, in which a flexible printed circuit board inserted into a connector body is placed near the connector body without bending the flexible printed circuit board in advance. An object of the present invention is to provide a flexible printed circuit board connector which can be led out at a predetermined angle.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a connector body containing contacts, a lock plate slidably supported in an opening of the connector body, and the connector. A hole into which a flexible printed circuit board which is inserted through an opening of the main body and comes into contact with the contact, is inserted;
A flat plate portion provided with the flat plate portion provided near the hole
And a substantially flat surface having a predetermined angle with the flat plate portion.
Therefore, the guide piece that regulates the direction in which the flexible printed board is led out , and both the connector body and the lock plate are also
Properly is characterized in further comprising a guide member locking pawls are formed for locking to either.

[0007]

According to the present invention, the guide member is locked to the connector body or the like by the guide piece of the guide member locked to the connector body and / or the lock plate .
This can restrict the direction in which the flexible printed circuit board is led out.

[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 denoted by the same reference numerals. 1 to 3, reference numeral 11 denotes a guide member for guiding the flexible printed circuit board 8 in a predetermined direction.
Reference numeral 1 denotes a flat plate portion 13 having a hole 12 into which the flexible printed circuit board 8 is inserted, a guide piece 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. And a 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 front end of the flexible printed circuit board 8 into the hole 12 of the guide member 11, the flexible printed circuit board 8 is connected to the upper surface of the lock plate 3 and the connector body 1. When the flexible printed circuit board 8 is inserted into the connector body 1, the leading end of the flexible printed circuit board 8 comes into contact with the bottom surface of the connector body 1, and the exposed conductive foil 9 at the leading end of the flexible printed circuit board 8 The conductive foils 9 of the flexible printed circuit board 8 are brought into conduction with the respective contacts 2 in the connector body 1 by contacting the contacts 2. When the lock plate 3 is pushed in this state, the front end of the flexible printed circuit board 8 is sandwiched between the lock plate 3 and the inner wall of the connector body 1 and the flexible printed circuit board 8 is pressed.
Is locked and locked.

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 claw 15 of the guide member 11 is
A, and the locking piece 16 of the guide member 11 is locked to the corner of the guide piece 7 of the lock plate 3. In this manner, the guide member 11 is locked on the upper surface of the connector main body 1, and the flexible printed circuit board 8 inserted into the hole 12 is guided by the guide piece 14 of the guide member 11 and is led out in a predetermined direction. .

As described above, according to the above embodiment, as shown in FIG. 3, the locking claw 15 of the guide member 11 is engaged with the concave portion 1A on the back of the connector body 1, and the locking piece 16 is moved. By locking to the corners of the guide pieces 7 of the lock plate 3, the guiding direction of the flexible printed board can be regulated by the guide pieces 14 of the guide member 11.

FIGS. 4 to 9 show a second embodiment of the present invention. This embodiment is different from the first embodiment in the structure of the guide member. The guide member 17 of the present embodiment has a structure in which locking pieces 19 are integrally formed at both ends of a guide piece 18, and a locking claw 20 is formed at a free end of the locking piece 19. As shown in FIGS. 4 and 5, the flexible printed circuit board 8 is
8, the guide member 17 is moved from the lock plate 3 side so that the locking claw 20 is brought into contact with the connector body 1.
To be locked to the back of the camera.

In the above embodiment, the guide members 11, 1
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 may be locked only to the lock plate 3.

[0014]

According to the present invention, as is apparent from the above-described embodiment, the connector body is formed by merely locking the guide member having the guide piece for regulating the lead-out direction of the flexible printed circuit board to the connector body. Has the advantage that the flexible printed circuit board inserted into the flexible printed circuit board can be led out in a predetermined direction, and the advantage that the durability of the flexible printed circuit board can be improved because the flexible printed circuit board does not need to be bent in advance. Things.
