Description

[Detailed Description of the Invention] [Summary] The sheet multi-stage mounting unit structure has intermediate rail positioning holes provided at a plurality of predetermined positions of the unit case housed in the block, and the intermediate rail By attaching the , it is possible to mount sheets of various sizes in multiple stages.

[Industrial application field]

The present invention relates to a sheet mounting structure in a block that stores sheets in a functional unit such as a communication device, and more specifically, the present invention relates to a sheet mounting structure in which sheets are divided into parts corresponding to one sheet and mounted in multiple stages. This relates to the mounting unit structure.

[Conventional technology]

Conventionally, communication devices have used printed wiring boards with functional circuit sheets, but as the number of sheets used increases, these sheets are separated by function, and block cabinets are installed for each functional group. The block is housed in the body, and the block is housed on a rack.

[Problem that the invention seeks to solve]

Even for sheets within a block that have the same function, it is more convenient for maintenance and testing to separate them into smaller units of function. However, in the above-mentioned conventional structure, since the size of one sheet is determined, there is a problem in that if the sheet is divided into small units according to functions, there will be wasted space on the sheet.

The present invention was created in view of the above points, and an object of the present invention is to provide a sheet multi-stage mounting unit structure that has a simple configuration and is capable of mounting each function in small units without wasting sheets. .

[Means for solving problems]

For this reason, in the present invention, a unit case body 3 is provided with a rail portion 6 having the same size as the seed accommodated in the block 1 and holding the printed board 5.5 degrees above and below.
and an intermediate rail 4 which is fixed at a predetermined position of the unit case body 3 and holds the printed boards 5, 5', and the unit case 2 is constituted by the rail portion 6 of the unit case body and the intermediate rail 4. It is characterized by the ability to mount printed boards of various sizes in multiple stages.

[Function] By providing a unit case consisting of a unit case body that is the same size as a normal sheet and an intermediate rail that is attached to a predetermined position, it is possible to divide a normal sheet into small units for printing. The plates can be mounted on the unit case in multiple stages.

〔Example〕

FIG. 1 is a diagram showing an embodiment of the present invention. In the figure, 1 is a block, 2 is a unit case, 3 is a unit case body, 4 is an intermediate rail, and 5° 5'' is a printed board.

In this embodiment, a unit case 2 consisting of a unit case main body 3 and an intermediate rail 4 having the same size as the sheets accommodated in a block l is provided, and printed boards 5, 5'' divided into small units according to functions are attached to the unit. It is designed to be housed in Case 2.

Figure 2 is for explaining this unit case 2.
FIG. 6 is a diagram of FIG.

In FIG. 2a, the unit case body 3 is formed of a metal plate and has the same size as a normal sheet, with rails 6 for guiding printed boards formed above and below it, and between the upper and lower rails. Holes 7 for positioning the intermediate rail are provided at a plurality of predetermined positions. Further, as shown in Figure 2C, the intermediate rail 4 is formed with an 8° and 8° turn in the vertical direction to serve as a rail for guiding the printed board, and a positioning protrusion 9 is formed at the base, as shown in Figure A. The projection 9 is fitted into the positioning hole 7 at a predetermined position of the unit case body 3 and fixed. The number and fixing positions of the intermediate rails 4 are determined by the size of the printed circuit board to be mounted, but for example, as shown in FIG. Two printed boards of the same size are mounted, two intermediate rails 4 are attached to the unit case 10 inside the block housing, and three printed boards of the same size are mounted. It is preferable to standardize the size of the printed board and the fixing position of the intermediate rail 4 so that it can be mounted.

Also, the rail part 6 and intermediate rail 4 of the unit case body
When the printed board 5 is inserted as shown in Figure 2 a, the gap g with the bottom of the unit case body is 8.8 degrees when the part 1 is folded.
It is necessary that the leads 12 of 1 do not come into contact with the bottom of the unit case body, and that spacers 13 are attached to at least four corners of the printed board 5.

Further, a pair of locking claws are formed at the upper part of the unit case 2, as shown in FIG.

In this embodiment configured in this way, printed boards divided into smaller pieces than normal sheets can be mounted in multiple stages. In addition, when it is sufficient to pull out the printed boards individually for maintenance, testing, etc., the unit case is
, 14° can be engaged with the locking holes 15 and 15° of the block 1 to be fixed.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to mount sheets divided into small unit functions in multiple stages with an extremely simple configuration and without wasting sheets, which is extremely useful in practice.
