Abstract

PURPOSE:To reduce the wiring space and prevent the interference between wirings by arranging terminal boards on the rear sides of a plurality of units in a housing, dividing the space formed on the rear sides of the units in the direction of the depth, and arranging the wirings while classifying according to the function. CONSTITUTION:A plurality of units 2 are kept in a housing vertically. The terminal board 3 on the rear side of each unit 2 has a connecting device 5 for an outside line cable 4 and a connecting device 7 for the connecting cables 6 between the units 2. Wiring space is formed in the rear of each unit 2, and divided into two in the direction of its depth. The cables 6 between the units 2 are arranged nearer to the terminal boards 3, and the outside line cable 4 is arranged and wired in the rear while being separated from the cables 6. Besides, a plurality of cable fixing and supporting devices 9 are provided between a right and left side-boards not shown in order to bind the rising part of the cable 4. And, this reduces the wiring space, prevents the inductive interference between the wirings, and facilitates the maintenance and inspection.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a housing for an electronic device in which a plurality of units are mounted.

[Conventional technology]

The conventional technique, as described in Japanese Patent Publication No. 56-9037, is to use the side surface of the housing to run the cable in the vertical direction, and when it reaches a position approximately at the height of the unit to be connected, it is placed on the floor. Run the cable parallel to the unit and connect it to the connection terminal on the back wiring board on the back of the unit.

[Problem to be solved by the invention]

According to this, as long as the cable is connected to the back wiring board of the unit, some kind of cable space is required on the back of the case, and since the cables are concentrated on the side of the case, a cable space for that purpose is required on the side. It was necessary to increase the width of the casing. In addition, if it is necessary to separate the cables for each function at a certain distance to prevent electrical noise, additional cable space will be required. It was necessary to carry out styling, fixing the cables at key points, and bending the cables multiple times before laying. Furthermore, the ease of construction, maintenance, and expansion of the cable must be done from the side, resulting in poor workability.

[Means to solve the problem]

In order to achieve the above objective, the rear of each unit mounted in multiple units is used as a cable space, and the cable space is further divided into two in the depth direction of the chassis, so that Pass multiple cable fixing supports almost parallel.

This is achieved by attaching and dividing the cables, and by making the cable fixing support structure capable of fixing the cables separated by a certain distance.

[Effect]

In the rear cable space of the divided unit, the rear back wiring board side of the unit is used as an inter-unit cable storage space, and the other side is used as an external line cable storage space to store cables. The inter-unit cable is fixed to the back wiring board side of the cable fixing support, and the external line cable is fixed to a surface of the cable fixing support opposite to the surface on which the inter-unit cable is fixed. Thereby, the inter-unit cable and the external line cable can be separated by a required distance by the cable fixing support. In addition, the open space on the back of the rear allows the installation of various cables.Since the back side is used as a cable space, the work of fixing cables and styling the cables is eliminated, and after completing the cable installation work, the cables can be fixed. The cable only needs to be fixed using the support, making it an easy and reliable cable laying method.It also makes it easy to separate the cables by function to prevent electrical noise, and the cable space can be placed on the back of the housing. By concentrating them, we improved workability, maintainability, and expandability, reduced dead space on both sides, and enabled high-density mounting.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in Section 1. This will be explained with reference to FIG. The housing 1 is composed of a plurality of units 2. A back wiring board 3 is provided at the rear of each unit 2, and an outside line cable connection device 5 for connecting an outside line cable 4 to the back wiring board 3.

Inter-unit cable connection devices 7 for connecting the inter-unit cables 6 are provided in the number required for the functionality of the unit 2, and the rear of the back wiring board 3 is secured as a cable space for the cables. Furthermore, a plurality of cable fixing supports 9 are passed approximately parallel to the floor surface on the left and right side plates 8 of the housing 1 so as to divide the cable space into two in the depth direction of the housing 1. The rear back wiring board side of the unit 2 is divided into an inter-unit cable storage space 10 for the inter-unit cable 6.
and the other side is an outside line cable accommodation space 11 for the outside line cable 4. The external cable 4 is accommodated in the external cable storage space 11 and connected to the external cable connection device 5 of the back wiring board 3, and is connected to the cable fixing support 9.
be fixed individually or collectively. The inter-unit cable 6 is accommodated in the inter-unit cable accommodation space 10 and connected to the inter-unit cable connection device 7 of the back wiring board 3 . The inter-unit cable 6 is fixed to a surface of the cable fixing support 9 that faces the surface on which the external line cable 4 is fixed. The shape of the cable fixing part of the cable fixing support 9 is approximately U-shaped, and the dimensions of this U-shape are the required distance between the external cable 4 and the inter-unit cable 6, which have different functions, to prevent electrical noise. Furthermore, both ends of the approximately U-shape are bent inward, so that the cable fixing part has no sharp corners, so that the cable will not be damaged even when the cable is fixed. If the external line cable 4 and the inter-unit cable 6 are fixed to this cable fixing support 9 as described above, the approximately U-shaped cable fixing support 9 is Depending on the shape, the cables can be separated by the required distance.

〔Effect of the invention〕

As described above, according to the present invention, various cable installation work can be carried out in the open space on the rear back side, and since the back side is used as a cable space, cable fixing work, cable styling work, etc. It reduces man-hours, and after the cable installation work is completed, the cable only needs to be fixed using a cable fixing support, making it an easy and reliable cable installation method. It is also easier to separate the cables by concentrating the cable space on the back of the housing.
It improves workability, maintainability, and expandability, reduces dead space on both sides, and enables high-density mounting.
