Description

[Detailed description of the invention] The present invention relates to a printed board that is installed adjacent to a storage frame or the like and constitutes an electronic device, and particularly relates to a printed board that is installed adjacent to a storage frame or the like and constitutes an electronic device. This relates to a plate contactor.

Generally, when printed boards are installed adjacent to each other, signals are exchanged between the printed boards not by contacting each other, but by using printed board socket terminals. Met.

However, in recent years, printed boards have become larger, the parts attached to them have become smaller, and the number of parts installed has increased.As a result, the range of circuits installed on printed boards has expanded, and the density of circuits has also increased. It was way.

As a result, if a plug terminal is provided to be connected to a socket terminal for a printed board in order to transmit and receive signals between the printed boards, the circuit provided on the printed board is restricted, making it impossible to use the printed board effectively.

Therefore, this problem has been solved by bringing contactors equipped with contact pieces provided on the printed boards into contact with each other, without going through socket terminals, in order to send and receive signals between the printed boards. ing.

Figures 1 to 3 show this type of conventional printed board contactor, where 1 is a printed board, 2 is a base made of an electrical insulator, and 3 is juxtaposed and protrudes in the longitudinal direction of the surface of the base 2. 4 is a plug terminal, and 5 is a frame (not shown), for example.
This is a socket terminal installed in a printed board storage container made of etc.

The base 2 is attached to both sides of the printed circuit board 1 in a direction perpendicular to the plug terminal 4 using, for example, screws.

The plug terminal 4 can be inserted into and pulled out from the socket terminal 5. When inserted, the plug terminal 4 is connected to the socket terminal 5, and the printed board 1 operates as an electronic device.

When the plug terminal 4 of another printed board 1 is inserted into the socket terminal 5 adjacent to the printed board 1 in operation, the connection is made.
Since the contact pieces 3 provided on the base 2 of each printed board 1 slide and come into contact with each other, mutual signals are exchanged via the contact pieces 3 without going through the socket terminals 5.

However, in the above-mentioned contactor, the base 2 is attached to the plug terminal 4 at right angles, which limits the circuitry provided on the printed board 1, which only hinders the effective use of the circuit space on the printed board 1. However, since the contact pieces 3 contact and slide with each other not only when inserted but also when pulled out, there is a drawback that the contact pieces 3, 3 are deformed and damaged.

The present invention eliminates the above-mentioned drawbacks, and its purpose is to provide a printed board contactor that prevents deformation and damage of the contact piece and also allows effective use of circuit mounting space on the printed board.

A printed board contactor according to an embodiment of the present invention will be explained below with reference to FIGS. 4, 5, and 6a and 6b.

1 is a printed board, 2 is a base made of electrical insulators attached to both sides of the printed board 1, 3 is a contact piece protruding from the base 2 and provided in parallel in the longitudinal direction, 4 is a plug terminal, and 5 is a A socket terminal, 6 is a semicircular projection provided at the center of both longitudinal ends of the base 2, and 7 is a relief groove of the projection 6, which is provided at the center of both longitudinal ends of the base 2 like the projection 6. .

The base 2 is provided on both sides of the printed board 1 parallel to the plug terminal 4.

Both the protrusion 6 and the relief groove 7 are provided approximately in the center of the contact pieces 3, 3, and in particular, the protrusion 6 can freely slide on the center part of the contact pieces 3, 3 of the base 2, where the relief groove 7 is provided. The protrusion 6 and the relief groove 7 can fit into each other freely, and the protrusion 6 and the relief groove 7
When the contact pieces 3, 3 provided on the bases 2 are fitted together, the contact pieces 3, 3 provided on the bases 2 come into contact with each other.

In the contactor having the above configuration, a base 2 provided with an relief groove 7 is provided adjacent to a printed board 1 having a plug terminal 4 connected to a socket terminal 5 and provided with a base 2 provided with a protrusion 6. When the plug terminal 4 of the printed circuit board 1 is inserted into the socket terminal 5, the contact pieces 3, 3 do not slide against each other but are attached to each other's base 2.
slides through the projection 6 and the projection 6 and the relief groove 7 fit into each other, the contact pieces 3 also come into contact with each other, and the plug terminal 4 is connected to the socket terminal 5.

Therefore, each printed board 1 exchanges signals with each other via the contact pieces 3, 3.

Note that when the plug terminal 4 is pulled out from the socket terminal 5, the contact pieces 3, 3 do not slide against each other as described above, but the projection 6 and relief groove 7 are disengaged, and the base 2 pulls out the projection 6. The contact pieces 3, 3 are released from contact.

In the embodiment, a substantially semicircular protrusion 6 has been described, but its shape is not limited to a semicircle, and may be, for example, triangular, rectangular, or the like.

According to the contactor having the above configuration, the base 2 is provided parallel to the plug terminal 4, and the base 2 is slidable via the protrusion 6 without the contact pieces 3 sliding against each other. When the protrusion 6 and the relief groove 7 are fitted together, the contact piece 3 comes into contact with the contact piece 3, and when the fit is removed, the contact piece 3 is released from the contact.This prevents the contact piece 3 from being deformed or damaged, and also prevents the contact piece 3 from being disposed on the printed board 1. Since the circuit is not limited, the space on the printed board 1 can be advantageously utilized.
