Description

[Detailed Description of the Invention] [Summary] A cabinet for mounting electronic equipment, which comprises a cabinet body consisting of a frame, an upper frame, and a lower frame, a cable duct fixed to the upper part of the cabinet body, and a cabinet connection. By constructing the structure with a support strut and a reinforcing strut, we were able to improve cable handling, cooling effects, and earthquake resistance.

[Industrial application field]

The present invention relates to the structure of a cabinet in which electronic equipment such as a communication device, a switching device, etc. is mounted.

In recent years, there has been a trend toward higher density of electronic equipment such as communication equipment, switching equipment, etc., which is equipped with electronic circuits, and it is inevitable that cabinet structures adapted to high-density technology, that is, high cooling efficiency, small space, and large number of There is a need for a cabinet structure that allows cables to be routed efficiently. Additionally, there is a strong demand for improved earthquake resistance.

[Conventional technology]

As shown in FIG. 8, the cable duct is suspended from the ceiling of the building above the cabinet.

Next, detailed structural examples of each will be explained using figures.

FIG. 9 is a sectional view of FIG. 8. In this diagram,
7 is a back cover, 8 is a support, 9 is a reinforcing frame for connecting and reinforcing the supports, 10 is a mounting bracket for mounting an electronic device, 11 is an electronic device, and 12 is a cable passage.

As shown in FIG. 9, conventional cabinets generally have a structure with supports at four corners.

[Problem that the invention seeks to solve]

This conventional structure was disadvantageous in terms of appearance and constructability. In addition, the cable entry port is made by drilling a hole in the ceiling of the cabinet, so when introducing cables with connectors that are commonly used in recent years, there is a problem that workability is poor, especially when performing additional construction due to expansion etc. There is. Furthermore, with this structure, the space for accommodating the cables covers the back side of the electronic device, so there is space between the electronic device and the cable passage, such as cable connection and inspection of the back side.
This requires space for work and maintenance, which is disadvantageous in terms of downsizing the equipment.

In addition, in the structure shown in Figure 9, in order to obtain sufficient earthquake resistance, the pillars themselves must have sufficient strength, which requires the pillars to be larger and weigh more. Therefore, in order to increase earthquake resistance, it was generally necessary to perform construction work such as installing an earthquake-resistant reinforcing beam at the top of the cabinet.

The present invention was created in view of the above points, and is intended to improve natural air cooling capacity and cable wiring processing efficiency in a cabinet that is equipped with electronic devices such as communication devices and switching devices that are equipped with electronic circuits.・The aim is to achieve improvements in earthquake resistance and appearance, and to achieve overall economicalization and miniaturization as communication and switching systems.

[Means for solving problems]

According to the present invention, this purpose is to provide an upper frame and a lower frame that are attached to the frame and the upper and lower parts of the frame so as to protrude to the back surface, and have notches on the back surface and the side surface on the back side of the periphery. The cabinet body consists of a frame, the cable duct is fixed to the top of the cabinet body and can accommodate cables without interfering with the cooling effect, the cabinet connection struts and reinforcing struts improve earthquake resistance, and the exterior appearance is improved. It consists of a front door (or cover), a back cover (or door), a side cover, and a cable duct cover.

[Effect]

The structure of the cabinet for mounting electronic equipment of the present invention has a cable duct in the upper part of the cabinet body, and notches are provided on the back surface around the upper frame and the lower frame and on the side surface on the back side. The structure has no obstacles such as pillars on the back side of the cable, making it easy to lay cables.At the same time, the connecting pillars and reinforcing pillars also provide sufficient earthquake resistance in a minimum space. Can be secured.

In addition, in the cabinet of the present invention, the cable duct has a structure in which the cable can be wired by floating it above the main body of the cabinet, which allows for good air flow and improves the cooling capacity of natural air cooling. Since it has a mating part that mates with the tip of the cable support, it can be assembled efficiently.
