Description

[Detailed description of the invention] The present invention relates to a printed circuit board connecting device that is particularly suitable for electrically connecting different printed circuit boards. The present invention aims to provide a printed circuit board connecting device that can perform continuous fixing.

Conventionally, lead wires were generally used when electrically connecting different printed circuit boards, and the exposed conductor portions at both ends were wound around the terminals installed on each printed circuit board, and then the winding was done partially. However, because the lead wires are flexible and it is necessary to wrap both ends of the lead wires around the terminals, the workability is poor, making mechanization and automation difficult. The drawback was that it was difficult to measure.

The present invention eliminates the above-mentioned drawbacks of the conventional method by using a flexible band-shaped conductor with elasticity at both ends, and attaching this conductor directly to a resin molded product, such as the cabinet itself, while attempting to connect it. The end of the printed circuit board is attached to the resin molded product and brought into contact with the end of the conductor to establish a connection.

One embodiment will be described below with reference to the accompanying drawings.

FIG. 1 shows the structure of a flexible band-shaped conductor used in the present invention, and FIG. 2 shows the structure of the connecting portion.

The strip-shaped conductor 1 is provided with protrusions 2 and 3 protruding perpendicularly to the length direction in close proximity to each end thereof, and both ends are folded back, and the folded tips are formed into a circle that bulges outward. The contact portion 4.5 is processed into an arc shape and has elasticity.

On the other hand, in a connecting portion for connecting printed circuit boards, 6 is a plastic molded body, such as an escutcheon or other structure in the case of a television receiver.

A plurality of grooves 7 for fitting and holding the conductor 1 are formed in parallel in the plastic molded body 6, and each groove 7
Concave portions 8 corresponding to the protrusions 2 and 3 of the conductor 1 are continuously formed in the conductor 1, while grooves 11 into which the ends of the printed circuit board 10 are fitted are formed at both ends, although only one end is shown in the drawing. .

Further, the plastic molded body 6 is provided with a thin wall portion 14 by forming recesses 12 and 13 from both sides in the middle to enable the connection of two printed circuit boards disposed at right angles to each other. Cage, plastic molded body 6
can be bent in any direction from this thin wall portion 14.

Furthermore, a fixing hole 16 corresponding to the screw hole 15 of the printed circuit board 10 is provided at the end of the plastic molded body 6.

Note that 17 is an electronic component mounted on the printed circuit board 10.

In the above configuration, the connection operation will next be explained.

First, the strip conductor 1 is attached to each groove 7 of the plastic molded body 6 constructed as shown in FIG.

At this time, the shapes of the contact parts 4 and 5 and the position of the groove 11 are adjusted so that the contact parts 4 and 5 of the strip conductor 1 protrude into the groove 11.
Set the depth etc.

In this state, the end of the printed circuit board 10 is fitted into the groove 11 as shown in FIG.

At this time, the connection copper foil part (not shown) on the back side of the printed circuit board 10 comes into contact with the contact parts 4 and 5 of each strip conductor 1, and the printed circuit board 10 and the other printed circuit board (not shown) are connected to the strip conductor 1. electrically connected through 1.

Then, the screws 18 are screwed into the screw holes 15 of the printed circuit board 10 through the fixing holes 16, or the printed circuit board 10 is mechanically fixed to the plastic molded body 6 using screws and nuts.

According to the above embodiment, the connection operation only requires inserting the conductor 1 into the groove 7 and fitting it into the groove 11 of the printed circuit board 10, and both operations can be easily performed, making it easy to mechanize and automate. It is measured.

Furthermore, when one printed circuit board 10 is located perpendicularly to the other printed circuit board, as shown in FIG. can be easily dealt with.

For example, when connecting a printed circuit board located perpendicularly to the printed circuit board mounted on the escutcheon, this can be easily achieved by providing a thin portion on a portion of the escutcheon as described above.

As explained above, according to the present invention, a strip conductor having elastic contact portions at both ends is attached to an insulator such as a plastic molded product, and a printed circuit board is attached so that the elastic contact portions appear at both ends of the strip conductor. By providing a fitting groove, it is possible to electrically connect a plurality of printed circuit boards via the strip conductor, and in this case, the operation for connection involves attaching the strip conductor to the groove and attaching the printed circuit board to the strip conductor. Only the fitting operation into the groove is required, and therefore mechanization and automation can be easily implemented.
