Description

[Detailed description of the invention] <Industrial application field> The present invention is effective when used in equipment such as a transducer that uses a plurality of printed boards.
The present invention relates to a printed board fixing structure that fixes multiple printed boards at once.

<Conventional technology> The conventional technology will be explained below with reference to the drawings.

FIG. 4 is a diagram showing a conventional technique, for example, a structure for fixing a printed board for a transducer.

In FIG. 4, among the plurality of printed boards, the printed board that inputs and outputs signals from the outside through the terminal T/lead _TR is particularly referred to as the basic printed board 1 here. A plurality of other printed boards each having a connector 2 at the connecting portion are vertically assembled to this basic printed board 1, and these other printed boards are here referred to as branch printed boards 3, 3, . . .
That's what it means. 4 indicates a transformer. Note that various other electronic components assembled on the printed board are omitted. During the manufacturing process, branch printed boards 3, 3,
. . . etc. are assembled on the basic printed board 1, the branch printed boards 3, 3, . Using the plate 5, the branch printed boards 3, 3, . Then case 8
Assemble.

<Problems to be solved by the invention> For this type of equipment, branch printed boards prepared for each function can be easily assembled;
Further, it is desirable that not only the manufacturer but also the user can easily change the branch printed board for changing specifications. However, with this conventional structure, it is necessary to remove the fixing screws 7 and the fixing plate 5, and such work requires extra effort (man-hours). This results in an invisible cost increase. Of course maintenance
This will also be disadvantageous in terms of product appeal, etc.

The present invention was developed in view of the problems of the conventional technology, and is a one-touch printing method with a simple structure that can substantially reduce costs by reducing the number of man-hours in the current manufacturing process. The purpose is to provide a plate fixing structure.

<Means for Solving the Problems> The printed board fixing structure of the present invention for achieving the above-mentioned object has a plurality of branched printed boards assembled on a basic printed board, and a fixing member is attached from the opposite side of the basic printed board. In the printed board fixing structure in which the printed board is fixed using The base printed board and the fixing member are pulled together by the elastic material to fix the printed board in the vertical direction, and after the printed board is fixed in the vertical direction, It is characterized by a case that fixes the left and right directions.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings. In the following drawings, parts that overlap with those in FIG. 4 are given the same numbers and their explanations will be omitted.

FIG. 1 is a diagram of a printed board fixing structure showing a specific embodiment of the present invention.

In FIG. 1, a reference numeral 9 is located between the basic printed board 1 and the fixing plate 5, with one end being engaged with a hook 10 attached to the basic printed board 1, and the other end being attached to the fixing plate 5. For example, it is a resilient material such as a coil spring that utilizes a tensile force and is provided to be locked to the hook 10'.
Here, "combined length of coil spring 9 and hook 10 (free length)"<"branch printed board 3, 3,
If the length dimension is ``...'', then the coil spring 9 will cause the basic printed board 1 and the fixed plate 5 to be pulled together, and the vertical direction of the branch printed boards 3, 3, ... will be easily and reliably moved. Can be fixed. Also, by making the width dimension of the fixed plate 5 slightly smaller than the inner dimension of the cases 8 on both sides,
At the same time as the case 8 is assembled, the branch printed board 3,
3. The left and right directions of... can be fixed.

With this structure, the work associated with assembling the branch printed boards 3, 3, ... and changing the combination of the branch printed boards 3, 3, ... as necessary can be done as follows. conduct. This will be explained using FIG.

FIG. 2 is a diagram for explaining the present invention.

In FIG. 2, the branch printed boards 3, 3, . . . are vertically fixed to the basic printed board 1 using the connectors 2 while the fixing plate 5 is pulled upward as indicated by the arrow α. After that, the grooves 5a of the fixing plate 5 are lowered so as to engage with the branch printed boards 3, 3, . . . and set in one touch. In this way, the work only requires a simple number of man-hours. That is, the number of man-hours in the current manufacturing process can be reduced, resulting in cost reduction.

By the way, the present invention is not limited to FIG. 1. That is, in addition to the material such as the coil spring 9, a generally known elastic material such as a rubber product may be used. Further, as shown in FIG. 3 which shows another embodiment, for example, a U-shaped relief part 3 is provided in the branch printed boards 30, 30, . . .
0a and a holding bar 50 provided with a groove 50a that can be fitted into the U-shaped relief portion 30a may be used instead of the fixing plate 5. This is an application range of the present invention that can be easily changed in design.

<Effects of the invention> As described above in detail with the embodiments, the printed board fixing structure of the invention has the following effects:
Since the branch printed board can be fixed in one-touch using elastic material and the case, it is easy to assemble and replace the branch printed board, making work more efficient in terms of specification changes and maintenance. Such a structure has the effect that it is possible to easily maintain insulation while fixing the printed board (this point is also difficult if fixing screws or the like are used).
