Description

The present invention relates to an electronic device in which a plurality of units of electronic devices are housed in a housing and a back wiring board is provided on the rear rear surface of each unit. The present invention relates to a case structure.

[Conventional technology]

The conventional technique is as described in Japanese Utility Model Laid-Open No. 59-111081.
Use the side of the housing to move the cable up and down, and when it reaches the height of the relevant unit to be connected, run the cable parallel to the floor and attach the cable to the back wiring board on the back of the unit. Connected to the connection terminal.

[Problems 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 cable space is required on the back surface of the housing, and the cable space is needed on the side surface for concentrating the cable on the side surface of the housing. It was necessary to increase the width of the body. Also, in order to prevent electrical noise, if it is necessary to accommodate the cables with a certain space for each function of the cable, an additional cable space is required, and consider the route of the cable so that the cables for each function do not approach. While performing style, fixing cables at required points and bending the cables multiple times,
It was necessary to lay it. Also, in terms of cable workability, maintainability, and expandability, it must be done from the side,
The workability is deteriorated, and even if the rail structure is used to pull out the cable, the number of parts is required, which causes a cost increase.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a low-cost electronic device housing structure that improves workability, maintainability, and expandability.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention has a back wiring board provided with connecting devices having different functions on the rear surface of the rear side, and a unit made of electronic equipment is accommodated in a housing in a plurality of units vertically, In the housing structure of an electronic device in which a cable space is defined at the rear of the back wiring board of each unit in the housing, an opening in which the cable space is opened is formed at the rear of the housing, and the cable space position in the housing is formed. A plurality of cable fixing supports mounted on both sides of the housing and arranged substantially parallel to the floor surface are provided along the vertical direction, and the unit is provided in the cable space in front of the cable fixing supports. One of the inter-cable storage space and the external cable storage space is divided and formed, and is located behind the cable fixing support in the cable space. A cable that has either one of the inter-unit cable accommodating space and the external cable accommodating space divided and is connected to one of the connecting devices of the back wiring board of the unit and has a specific function in the one accommodating space. Is arranged vertically, and in the other accommodation space, a cable that is connected to the other connection device of the back wiring board of the unit and has a function different from a specific function is wired, and The cable and the cable in the other accommodating space are characterized in that they are fixed and held in a substantially vertical direction with respect to the cable fixing and supporting device with a required space therebetween.

[Action]

As described above, the cable space in the housing is divided into the one accommodation space and the other accommodation space, and the cables having the specific functions and the cables having the different functions are wired in these accommodation spaces in the vertical direction. As a result, the cables are centrally routed on the back of the case, and both cables with different functions can be routed separately.
Therefore, the space at the rear of the housing can be effectively used for cable wiring. Therefore, the width direction of the side surface of the housing does not increase.

Further, as described above, not only the cables having both functions are separately laid out in each of the accommodation spaces, but also the cable fixing support is fixed and held in a substantially vertical direction with a necessary interval for each function. In order to prevent electrical noise, it is easier to divide cables by making more effective use of the existing space. Furthermore, not only can the cable be laid in the rear of the housing, but also at the same position in cable construction, maintenance, expansion, etc., these operations can be performed smoothly. Moreover, comparing with the conventional example using the rail structure,
In addition to the cable support 9, it suffices if it has a means for fixing and holding the cable for each function, so that the number of parts is not increased and therefore the configuration can be simplified, resulting in an increase in cost. Can be prevented.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

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 the back wiring board 3 is provided.
An external cable connecting device 5 for connecting the external cable 4 and an inter-unit cable connecting device 7 for connecting the inter-unit cable 6 are provided in the same number as necessary for the function of the unit 2. Further, the rear portion of the back wiring board 3 is secured as a cable space for the cables, and further, the left and right side plates 8 of the housing 1 are attached to the floor so that the cable space is divided into two in the depth direction of the housing 1. And pass a plurality of cable fixing supports 9 almost in parallel,
The unit 2 is mounted and divided, and the rear back wiring board 3 side of the unit 2 serves as an inter-unit cable housing space 10 for the inter-unit cable 6 and the other serves as an outside wire cable housing space 11 for the outside wire 4. Therefore, the cable space is divided into the inter-unit cable accommodating space 10 at the front position and the outside wire cable accommodating position 11 at the rear position with the cable fixing support 9 as a boundary. The external cable 4 is housed in the external cable housing space 11, connected to the external cable connecting device 5 of the back wiring board 3, and fixed to the cable fixing support 9 individually or collectively. The inter-unit cable 6 is housed in the inter-unit cable housing space 10 and is connected to the inter-unit cable connecting device 7 of the back wiring board 3. The inter-unit cable 6 is the cable fixing support 9
Therefore, it is fixed to the cable fixing support 9 via the inter-unit cable fixing support 12 at a position close to the back wiring board 3 so that the external cable 4 is fixedly held at a required distance. The inter-unit cable fixing support 12 is fitted into the C-shaped cable fixing support 9 while holding the inter-unit cable 6 as shown in FIG. An opening (not shown) is provided at the rear of the housing 1 to open the cable space.
It is usually closed by a door.

As described above, in the case structure of the embodiment, the cable space in the case 1 is divided into the inter-unit cable accommodation space 10 and the outside line cable accommodation space 11, and the inter-unit cable 6 is provided in the accommodation space 10. Since the external cables 4 are laid in the housing space 11 along the vertical direction, the cables are centrally laid on the back surface of the housing, and both cables 6 having different functions are provided.
4 can be separately wired, so that the space at the rear of the housing can be effectively used for cable wiring. Therefore, the width direction of the side surface of the housing does not become large as compared with the conventional technique in which the cable is pulled using the side surface of the housing.

Further, as described above, not only the cables 6 and 4 are separately wired for each of the accommodation spaces 10 and 11, but
Since they are fixedly held to the cable fixing support 9 with a necessary interval for each function, in order to prevent electrical noise,
By making more effective use of the existing space, cable segmentation becomes easier. Therefore, compared to the conventional example, the cable can be easily divided without adding a cable space.

Furthermore, not only can the cables be laid behind the housing 1, but also at the same position for cable construction, maintenance, expansion, etc., these operations can be performed smoothly. Moreover, as compared with the conventional example using the rail structure, in addition to the cable support 9, only a means for fixing and holding the external cable 4 and the inter-unit cable 6 is sufficient. Therefore, the number of parts is increased. Therefore, the structure can be simplified, and the cost can be prevented from increasing.

〔The invention's effect〕

As described above, according to the present invention, the cable space provided in the rear portion of the unit in the housing is divided into the inter-unit cable accommodation space and the external line cable accommodation space by using the cable support, and the respective accommodations are accommodated. The cables that connect to the unit are laid out in a space corresponding to each function, and the cables are fixedly held on the cable support so that each cable has a required interval for each function. Cables can be centrally wired, the width direction of the side surface of the housing does not become large, and the cables can be easily divided without adding a cable space. Since the work can be performed at a position, the workability is smooth and the configuration can be simplified, resulting in workability and maintenance. , The effect of expansion and the like may provide a good and inexpensive housing structure.
