Description

[Detailed Description of the Invention] The present invention relates to a slim communication device frame structure.

In recent years, with the development of integrated circuits, it has become possible to miniaturize electronic devices in various ways, and for communication devices, the rack width (520 to 600 mm) of conventional devices has been reduced to a fraction (1/4 to 1/4 to 600 mm).
A building block method in which the entire electronic circuit is divided into 1/5) and slimmed down, and at the same time the entire electronic circuit is divided into functional blocks, each of which is connected physically and electrically to each other to form the necessary electronic device. There is a remarkable trend in the adoption of

The main reason for this trend is that while it allows equipment manufacturers to reduce the number of types of circuits and mechanical blocks and provide the equipment that users want in the shortest possible time, it also reduces maintenance costs for users. In many cases, repairs can be made by replacing just the module that is in poor condition, and it is also small and lightweight, making it easy to handle.

The general configuration of a communication device based on the building block method is to install a connector for connecting modules at a position that can be shared within a rack frame that accepts various modules with the same or similar shapes but different functions. This is achieved by housing various cables connecting the modules and devices through the cable.

In addition, the structure of each component must be shaped to suit operating conditions such as maintenance and installation methods. In particular, the form of the rack frame not only has the function of storing the aforementioned module connection connectors and various cables, but also the interconnected power supply device, distribution switching device, etc., which are installed facing each other on the back side, so that they can be connected economically, electrically, and efficiently. In terms of cable accommodation, etc., it must be possible to connect over the shortest possible distance.

The frame structure of conventional equipment, which is slim and employs a modular building block system, generally consists of pillars with an F-shaped cross section with one open section on each side, as shown in Figure 1. They are separated and placed facing each other, and are made into an integral frame by screws or welding via connecting plates at the upper and lower ends of the frame.

In addition, the connector on the mounting side that connects the modules is
The left and right F-shaped supports are fixed to the inner lugs of the supports from the front by fastening means such as screws, so that the positioning corrector 11 is provided for each module to position and guide the module in order to prevent the module from being misfitted due to the left and right bending of the middle part of the supports.
A means is used to secure it to the left and right pillars.

The structure of such a conventional device consists of two pillars, which causes many problems in terms of economy and operation.

In other words, the need for a positioning corrector at the end of the rack and the positioning corrector at the intermediate part of the rack requires an enormous amount of man-hours to connect them, as well as encroachment on the cable space of the positioning corrector and the need for cables when adding or relocating modules. Examples include damage prevention during the introduction and decommissioning work.

FIG. 1 is a diagram showing a typical communication equipment rack structure that is a conventional slim type and employs a building block system. In the figure, reference numeral 1 denotes a frame support having an F-shaped cross section, reference numeral 2 a connecting plate for integrating the left and right F-shaped cross-section supports at the upper and lower ends of the frame, and reference numeral 3 electrically connecting the frame to the frame. It is a module equipped with a plug-in connector 4 for the purpose of use, and reference numeral 5 is a rack frame side connector mounted on the front surface of the internal prong 6 of the F-shaped cross-section column 1 to receive the module.

Further, reference numeral 7 is an inter-module cable that organically connects the modules 3 via the rack frame side connector 5, and reference numeral 8 is an external line cable that supplies electrical signals from other devices, power supply, etc. It is housed in a space defined by the F-shaped cross-section support 1.

Incidentally, the connection with the rear device is made by a cable 10 passing through the gap 9 between the F-shaped cross-section struts 1.

Further, reference numeral 11 is a positioning corrector for the middle part of the F-shaped cross-section column, and its main purpose is to prevent the module 3 from mating due to left and right deflection. The structure is arranged by module.

In such a configuration, as mentioned above, the cable space of the positioning corrector 11 is infringed, and since the communication device is usually installed with any device close to the rear, front access is common, and the storage cable is This becomes a major obstacle when expanding or relocating units 7 and 8.

Furthermore, the extremely uneconomical structure of the rack frame increases the cost of the equipment, resulting in poor competitiveness.

An object of the present invention is to provide a rack frame structure for a communication device that can eliminate the above-mentioned conventional difficulties and reduce costs.

In order to achieve the above object, the rack frame structure for communication equipment according to the present invention is slimmed down in the width direction of the rack, and at the same time blocks the entire electronic circuit into functional units, each of which is physically and electrically interconnected as a single module. In a communication equipment frame structure that adopts the building block method in which the necessary equipment is connected, one frame column is extruded so that the cross section is H-shaped or U-shaped, and the open end of this frame column is Attach rack-side connectors using any tensioning means so that the module can be received from the open end, bringing them into close contact with both outside sides of opposite sides with H
Cables for interconnecting modules and cables introduced from external devices are housed in the internal space of the frame support, which is shaped like a letter or a U-shape.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

Figures 2 and 3 show first and second embodiments of the slim building block system rack structure for communication equipment according to the present invention, and in both figures, the parts corresponding to those in Figure 1 are for the sake of comparison. have previously been given the same reference numerals.

The first embodiment of the present invention uses an extruded U-shaped frame column having a cross section with at least one open end, and has module side connectors on both outside sides of the frame column facing each other. A rack frame side connector 5 for receiving the connector 4 is attached by an arbitrary tightening means. Further, an inter-module connection cable 7 and an external line cable 8 are housed in the U-shaped internal space.

Next, in the second embodiment of the present invention, an H-shaped extruded frame column 13 is used as a frame column having a cross section having at least one open end. Similar devices (same as those in the embodiment) are integrally installed facing each other.

The electrical connection between the front installation device and the rear installation device of this second embodiment is achieved by a cable 10 connected to the back of the rack frame side connector 5 in both outside spaces set to an arbitrary width. is achieved.

As is clear from the above explanation, the frame structure for communication equipment of the present invention, which is slim and adopts the building block method, has a lower frame structure than the conventional one.
It has many advantages, such as reducing the number of component parts and achieving a significant cost reduction, as well as greatly improving the efficiency of installing and relocating storage cables.

The specific structure of the rack frame structure for a communication device according to the present invention is not limited to the above-mentioned embodiments, and may be modified in various ways, such as providing protective covers for the cable 10 and the rack frame side connector 5 on both outer sides of the rack support. Modifications are possible, and the frame structure for a communication device that is slim and adopts the building block method according to the present invention, including the above-mentioned modifications, falls within the scope of the utility model registration claims.
