[Problems to be solved by the device]

 Since the conventional chassis is configured as described above, brackets for supporting the printed circuit boards are assembled on the base plate for each printed circuit board, and the printed circuit boards are individually fixed to the brackets with screws. However, there is a problem in that the process becomes complicated, it takes time and labor to process, and it requires extra space and increases the weight.

The present invention has been made in order to solve the above problems, and an object thereof is to provide a chassis in which a base plate supporting a printed circuit board and a bracket are integrally formed.

[0005]

[Means for Solving the Problems]

 The chassis according to the present invention is inserted between a storage case, a print substrate arranged in the storage case, and the facing surfaces of the storage case and the printed circuit board, and is integrally fixed to the print substrate. And a bracket having a sliding surface in contact with the inner peripheral surface of.

[0006]

[Action]

 In the chassis according to the present invention, the bracket is fixed by the printed circuit board, and the sliding surface in contact with the inner peripheral surface of the storage case is formed on the bracket, so that the structure of the chassis is simplified.

【Example】

 An embodiment of this invention will be described below with reference to the drawings. FIG. 1 is a first embodiment of the present invention, in which a chassis is composed of one printed circuit board and four brackets. In the figure, 1 is a storage case, 2 is a chassis, 3 is a printed circuit board, and 4, 5, 6 and 7 are brackets. The brackets 4, 5, 6 and 7 are inserted into the upper and lower portions between both side surfaces 3a and 3b of the printed circuit board 3 and the inner side surfaces 1a and 1b of the storage case 1 facing the printed circuit board 3, respectively, and are attached to the bracket. The integrally formed section is fixed to the printed board 3 with screws 8 through L-shaped mounting portions 4a, 5a, 6a and 7a, and the upper surfaces 4b and 5b of the brackets 4 and 5 and the lower surface 6b of the brackets 6 and 7 are attached. And 7b and the outer edge end surfaces 4c, 5c, 6c and 7c of the brackets 4, 5, 6 and 7 form sliding surfaces for the upper and lower and left and right inner peripheral surfaces of the storage case 1, respectively.

Next, the operation will be described. By configuring the chassis 2 as described above, the brackets 4, 5, 6 and 7 are supported by the printed circuit board 3 and slide surfaces 4b, 5b which come into contact with the upper, lower, left and right inner peripheral surfaces of the storage case 1. , 6b, 7b and 4c, 5c, 6c, 7c can be formed so that they can be inserted into and removed from the opening on the front surface of the storage case 1 and fix the position of the chassis 2 in the case 1.

FIG. 2 shows a second embodiment of the present invention, in which the chassis is composed of two printed circuit boards and six brackets. In the figure, 1 is a storage case, 9 is a chassis, 10 and 11 are printed circuit boards, and 4, 5, 6, 7, 12 and 13 are brackets. Since the brackets 4, 5, 6 and 7 have the same shape as that of the first embodiment, the description thereof will be omitted. The brackets 12 and 13 are in contact with the upper and lower portions of the facing surfaces 10a and 11a of the printed circuit boards 10 and 11, respectively, and the brackets 12 and 13 are attached to the printed circuit boards 10 and 11 via mounting portions 12a and 13a having an L-shaped cross section integrally formed with the brackets. And are fastened together with brackets 4, 5, 6 and 7 by means of screws 14, on the upper surfaces 4b, 5b and 12b of the brackets 4, 5 and 12 and on the lower surfaces 6b, 7b and 13b of the brackets 6, 7 and 13, and The outer edge surfaces 4c, 5c, 6c and 7c of the brackets 4, 5, 6 and 7 form sliding surfaces for the upper, lower, left and right inner peripheral surfaces of the storage case 1, respectively.

Next, the operation will be described. By configuring the chassis 9 as described above, the brackets 4, 5, 6, 7, 12 and 13 and the printed circuit boards 10 and 11 are mutually supported and fixed in position. 12 and 13 form sliding surfaces 4b, 5b, 6b, 7b, 12b, 13b, and 4c, 5c, 6c, 7c in contact with the upper, lower, left, and right inner peripheral surfaces of the storage case 1, and the storage case 1 The chassis 9 can be inserted and removed from the front opening of the storage device 1 and can be mounted on the storage device 1 by itself, so that the position of the chassis 9 in the storage case 1 is fixed.

In the above embodiment, the case where the printed circuit boards are one and two chassis has been described, but in the case of two or more chassis, the intermediate brackets 12 and 13 mounted between the printed circuit boards are added. By doing so, it can be configured in the same manner and is included in the present invention. It is possible to cope with the variation in the number of printed circuit boards to be attached by simply preparing the brackets 4, 5, 6 and 7 for both ends attached to both ends of the chassis and the brackets 12 and 13 for the intermediate. The brackets for both ends and the middle one have the same shape, so you only need to prepare one type for each, and if you prepare the brackets with different width dimensions, you can mount the storage case and the printed circuit board as required. You can also assemble the chassis according to the intervals.

[Effect of the device]

 As described above, according to this invention, the chassis is connected and supported by the bracket and the printed circuit board, and the upper and lower surfaces of the bracket and the outer edge surfaces are formed with the sliding surfaces in contact with the upper and lower sides of the storage case and the left and right inner peripheral surfaces. The chassis has a simple structure that makes it easy to assemble and reduces weight, and the bracket that slides in contact with the inner peripheral surface of the storage case with a wide upper and lower surface As a result, the printed circuit board has the effect of being reliably supported in the case.
