DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board connecting apparatus for connecting printed circuit boards having a high degree of integration.

[0002]

2. Description of the Related Art Consumer electronic devices have complicated electronic circuits as their functions have been diversified, and the degree of integration of electronic components has increased dramatically. In particular, television receivers and video tape recorders having a built-in reception function for satellite broadcasting and teletext broadcasting are becoming mainstream.

A printed circuit board used in such a conventional electronic device is configured for each functional block, and a printed circuit board 12 is automatically inserted from above a connector 11 as shown in FIG. After the insertion, the printed circuit board fixing claws 15a and 15b provided on both side ends of the connector 11 are pulled to fix the printed circuit board so that the board does not fall off. Therefore, the connector 11
Has become larger, the structure is complicated, and the number of assembling steps is increasing.

[0004] As shown in FIG.
Reference numeral 4 is formed by bending a flat plate into a U-shape, and the printed circuit board 12 can be inserted only above the connector in a direction perpendicular to the direction B.

[0005]

In such a conventional configuration, the insertion of the multilayer printed circuit board 12 into the connector 11 is limited only to the vertical direction, so that the chuck of the automatic insertion machine does not come into contact. Components must be placed away from the connector. For this reason, the degree of integration of the component arrangement on the board is reduced, and it is difficult to insert and remove the printed board 12 from the connector 11 with a small space. Further, claws 15a and 15b for fixing the printed circuit board are provided on both side ends of the connector 11, which complicates the configuration of the connector, increases the shape, and increases the number of assembling steps. Furthermore, when the printed circuit board is slid sideways from the longitudinal direction of the connector to be inserted, the pins 1
4 is caught on the front end of the printed circuit board or the board terminal 13,
There were problems such as the pin 14 being bent or broken.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem, and provides a highly integrated structure in which components can be arranged also around a connector. It is an object to provide a board connection device.

[0007]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a claw fitted into a recess of a printed circuit board, a hook provided at the other end for fixing the printed circuit board, and a semicircular cross section. The printed circuit board is slid laterally from the arrangement direction of the connector pins into the groove of the connector having a plurality of gutter-shaped connector pins having the above, and is fixed by the hooks.

[0008]

With this structure, the printed circuit board inserted from the side slides on the gutter-shaped pins so that the claws are fitted into the concave portions provided at the front end of the printed circuit board, and the other end of the printed circuit board is connected to the end of the connector. It is fixed by the hook provided. As a result, the printed circuit board is fixed to the connector so as not to move up, down, left, and right.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A printed circuit board connecting device according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1 (A), the claw 4 shown in FIG. 1 (B) is provided on the inner side of the groove 8 of the connector 1 (closed side abutting wall surface) . A plurality of gutter-shaped connector pins 2 are provided.
a and 3b are provided integrally with the connector 1 main body . The hooks 3a and 3b are hook-shaped and elastically deformable.
Are supported in a cantilever shape, and form a pair facing each other.
A recess 6 is formed at the left end of the printed circuit board 5 so as to be fitted with the projection 4, and a plurality of board terminals 7 are provided on both sides at positions corresponding to the pins 2 a provided on the connector 1.

The printed circuit board 5 constructed as described above is slid in the direction A while the lower end of the printed circuit board 5 is in contact with the groove 8 of the connector 1 and is inserted until the claw 4 is fitted into the recess 6. At this position, the hooks 3a and 3b operate to fix the right end of the printed circuit board 5. Since the connector pins 2 are formed in a gutter shape, the board terminals provided on the printed board 5 slide smoothly.

As described above, the printed circuit board 5 is automatically inserted by the connector having a simple structure, and is fixed so as not to fall off. Further, since the printed circuit board is slid and inserted from the side, other components can be arranged around the connector 1 as close as possible.

In this embodiment, the hooks 3a and 3b are formed integrally with the connector 1 and are urged. However, the hooks 3a and 3b may be separately urged by using a spring.

[0013]

As is clear from the invention of the above embodiment, according to the present invention, the printed circuit board can be automatically inserted from the lateral direction of the connector. No vertical space is required for attachment and detachment, and the degree of integration of parts can be increased. Also, automatic insertion by the automatic insertion machine becomes easy.

Further, since the printed circuit board inserted into the connector is fixed by a hook biased by a projection provided on the connector, the structure of the connector is simplified, and the printed circuit board is connected to the board terminal by a gutter-shaped pin. Therefore, the connection strength is high and a highly reliable connection is possible.
