Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a printed wiring board mounting structure for connecting two printed wiring boards (hereinafter referred to as P boards).

Prior Art In a P-board device in which two printed wiring boards are electrically connected, one P-board must be connected to the other P-board in order to replace or inspect parts on the P-board after assembly. It is necessary to make it relatively movable.

For this reason, in the past, both P plates were electrically connected using a flexible P plate, and the mechanical attachment of both P plates was carried out using other mounting fittings using screws or the like.

Problems to be Solved by the Invention However, with the above configuration, when the mounting bracket is removed and both P plates are moved relative to each other, the flexible P plate cannot be moved beyond the movement range determined by the length of the flexible P plate, etc. As a result, a strong force was applied to the connection point between the flexible P plate and the P plate, resulting in peeling of the conductive foil or disconnection.

The present invention provides a P plate mounting structure that solves these problems.

Means for Solving the Problems In order to solve the above problems, the mounting structure of the P plate of the present invention has connection parts at both ends that are inserted into the connection holes of the P plate, and are parallel to each other. a plurality of elastically deformable lead terminals arranged as shown in FIG. These terminals are curved in the same direction.

Effect According to the mounting structure having the above configuration, each lead terminal constituting the mounting structure can be elastically deformed, so by bending the lead terminal using this elastic deformation, the relative position of both P plates is It is possible to change the positional relationship.

Moreover, since the curved portion of each lead terminal, which has been curved in advance, is angularly deformed in the direction of further curving, stable curving can be achieved, and it is easy to return to the original state.

Embodiment FIG. 1 is a perspective view showing a support member used in the P plate mounting structure of the present invention.

In Fig. 1, 1a, 1b, 1c...1n are lead terminals made of elastically deformable phosphor bronze, etc., and at both ends there are connection parts 2a, 3a that can be inserted into the connection holes of the P plate, respectively. ,2b,3b

...4n and the curved points 5a, 5b...5n and the connecting portions 3a, 3b...3n are integrally connected by insulating resin materials 6, 7, respectively.

FIG. 2 is a perspective view of a P plate device in which two P plates are joined using the support member having the above-described structure, and FIG. 3 is a sectional view of the same side.

In FIGS. 2 and 3, 12 is the first P
Plate 14 indicates a second P plate provided with a first metal frame 15 on its outer periphery.

In the connection holes of the second P plate 14, the connection portions 2a, 2b, . . . 2n of the lead terminals are provided, respectively.
By bringing the insulating material 6 into contact with the surface of the second P plate 14, the insulating material 6 is inserted in a positionally regulated state, and is coupled to the second P plate 14 by solder.

Further, the other connection portion 3a of each lead terminal,
3b...3n are inserted into the connection holes of the first P plate 12 in a state where the position is regulated by bringing the insulating material 7 into contact with the surface of the first P plate 12, and solder. It is connected to the first P plate 12 at.

Reference numeral 10 designates a third P plate, and a second metal frame 11 is fixed to the outer periphery of the third P plate. The third P plate 10 and the first P plate 12 are connected to each other by a lead wire 13.

A mounting piece 16 is provided on the upper side of the first metal frame 15.
is formed, and by fixing this mounting piece 16 to the second metal frame 11 with screws 17, the relative relationship between the first metal frame 15, the second metal frame 11, and the first P plate 12 is fixed. The location is regulated.

That is, the second metal frame 11 is attached to the mounting piece 16.
This is a fixing portion that removably engages with a locking means using a screw 17, and regulates the relative position of the first P plate 12 and the second P plate 14 when engaged.

In the above assembled state, the second and third P plates 1

The second and third P plates 1 are further curved at the 5n portion.
Numbers 4 and 10 are separated and parts can be replaced.

Effects of the invention As described above, according to the P plate mounting structure of the present invention, when necessary, a part of the lead terminal can be elastically deformed to cause one P plate to rotate relative to the other P plate. Therefore, it is easy to move and restore.

Furthermore, since a curved part is formed in a part of the lead terminal, it can be slightly moved in the directions of arrows B and C by deformation of this curved part, and the first and second metal frames 1
Even if there is a slight difference in height between 5 and 11, the curved portion can be elastically deformed to easily adjust and assemble.
