Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an electronic device in which a plurality of units of electronic equipment 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 device casing structure.

[Conventional technology]

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

[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 side of the housing, and the cable space is needed on the side surface to concentrate the cables on the side surface. ,
It was necessary to increase the width of the case. Also, the workability, maintainability, and expandability of the cable must be taken from the side, and even if the cable was pulled out as a rail structure, the number of parts required was that much, which was a cause of cost increase. . Further, when the cable is routed into the housing, it is necessary to perform bending work of the cable a plurality of times while laying the cable in order to fix the style of the cable and to lay it.

The present invention has been invented in view of the above-mentioned problems of the conventional art, and an object of the present invention is to provide a housing structure for an electronic device in which the cable routing work is improved.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention has a back wiring board provided with a plurality of subscriber cable connecting devices on a rear rear surface thereof, and accommodates a plurality of units consisting of electronic devices in a housing along a vertical direction. In the electronic device casing structure, an opening is formed in the rear surface of the casing, and a cable introduction port communicating with the opening is formed at a vertical position on the rear surface of the casing, and the back wiring of each unit in the casing is formed. The rear part of the board shall be a cable space that communicates with the cable inlet and the opening and in which a cable connected to the connection device of the back wiring board can be wired, and inside the cable space of the housing, on both sides of the housing. A plurality of cable fixing supports mounted substantially parallel to the floor surface are attached in the vertical direction, and the cables fixed to the cable fixing supports are drawn from the cable introduction port and connected to the connecting device. It is characterized in that the fixing and holding in a vertical direction.

[Action]

The cable is guided up and down vertically into the cable space inside the housing from the cable inlet, and is approximately 90 at the height of the back wiring board of the corresponding unit.
After refracting to °, it is connected to the device for external cable connection on the back wiring board. As a result, the work of laying the external cable can be done in the open space on the back of the rear part, and by pulling the cable vertically, the man-hours such as cable fixing work and cable styling work are eliminated, and the cable laying work is completed. After that, it suffices to fix the cable to the cable fixing support, which makes it easy and reliable to lay the cable, and also the cable space.
By concentrating on the back of the case, workability, maintainability, and expandability were improved, the dead space on both side plates was reduced, and high-density mounting was possible.

〔Example〕

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

The housing 1 is formed in a box shape so as to accommodate a plurality of units 2 including electronic devices in the vertical direction.
The back wiring board 3 is provided on the rear rear surface of the back wiring board 3.
The external cable connecting device 5 of the external cable 4 is provided in the unit 2 for the capacity of the external cable 4 accommodating capacity of the unit 2. In addition, an opening is formed on the back surface of the housing 1, and
A cable introduction port 6 that communicates with the opening is formed. The rear portion of the back wiring board 3 inside the housing 1 is secured as a cable space for the external cable 4.
Therefore, the cable space communicates with the opening of the housing 1 and the cable introduction port 6. The cable inlet 6 is the housing 1
It is formed by notching the rear parts of the upper and lower walls, respectively, and can be pulled in from either of them. Further, in order to fix the external cable 4 to the back side of the left and right side plates 7 of the housing 1, a plurality of cable fixing supports 8 are passed and attached substantially parallel to the floor surface, so that the cable fixing supports 8 are attached. A plurality of units are installed in the cable space of the housing 1 along the vertical direction.

The plurality of external cables 4 vertically fall or rise from the cable introduction ports 6 on the upper surface or the lower surface, and are guided along the plurality of cable fixing supports 8 and the corresponding back wiring board 3
Is bent at about 90 ° at a height of about 90 ° and is connected to the external cable connecting device 5. After the work of laying the plurality of outer cable 4 is completed, the outer cable 4 is fixedly held to the cable fixing support 8 individually or collectively. In this case, for the fixed holding, it is preferable that the external cable 4 can be easily tied, but the external cable 4 can be easily released. The opening of the housing 1 is normally closed by a door.

〔The invention's effect〕

As described above, according to the present invention, the outer cable is guided from the cable introduction port to the cable space in the housing, and the guided outer cable is fixed in the cable fixing support in a substantially vertical direction. Since it is configured to concentrate the external cable in the, the work of laying the external cable can be performed in the open cable space on the rear back of the chassis, and the cable fixing work can be performed by pulling the cable vertically. Easy and
A reliable cable laying method can be used to improve workability, maintainability, and expandability.

In addition, since the cable space is only on the rear side, no cable space is required on the side, and the space is also used for the case where the back side is a ventilation duct for air cooling.
Since it will be used, it is possible to implement a wide range of high-density mounting as a device.
