An elastic member 7 deformed along and brought into close contact with the outer shape of the signal cables 3 is attached to and installed on the cover plate 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable introduction structure for a housing of a communication device or the like. 2. Description of the Related Art In recent years, with the speeding up of signals in communication systems and the diversification of functions, sophistication of system software development and shorter delivery time have been demanded. Therefore, various software development support devices are connected to a communication device installed on the site to develop and debug operating software of a communication system. In the field installation, the signal cable between communication devices is connected to the shortest length as the signal speed increases.However, when connecting the software development support device to the communication device during the development period of the operation software, it may cause a signal delay. It is required to connect the signal cable to the minimum length so that it does not occur, and to minimize the inflow of external air so that the cable introduction hole for passing the signal cable does not impair the air cooling effect due to natural convection inside the communication device. There is.

2. Description of the Related Art Conventionally, as shown in the external perspective view of FIG.
The housing 11a of the communication device 11 has a cable introduction hole 11a-1 at the ceiling.
The software development support device 12 is placed as close to the communication device as possible, and its signal cable 13 uses the cable introduction hole 11a-1 on the ceiling part together with the general signal cable 14 from other devices not shown. It is connected to the communication control circuit 15 that is introduced and installed internally.

[0003]

However, if such a conventional cable introduction hole is used, the software development support device is placed as close as possible to the communication device, but there is a problem that the length of the signal cable becomes long. ..

In view of the above problems, the present invention provides a cable introduction structure that connects a signal cable connecting a communication device and a software development support device at the shortest distance and does not impair the air cooling effect due to natural convection inside the communication device. The purpose is to do.

[0005]

In order to achieve the above object, in the cable introducing structure of the present invention, the casing cover of the communication device is a communication control in which the signal cable of the software development support device is installed in the communication device. A cable introduction hole should be drilled at the position where it can be connected to the circuit at the shortest distance, or the housing cover should have a comb-shaped cable arranging support member fixed near the cable introduction hole, or the cable introduction hole should be covered and the signal should be covered. A closing plate having a cut-through hole through which a cable is inserted is slidably attached to the housing cover, and an elastic member is attached to the closing plate so as to deform and adhere along the outer shape of the signal cable.

[0006]

With the casing cover of the communication device, the signal cable can be connected in the shortest distance by forming the cable introduction hole at the position where the signal cable of the software development support device is connected to the control circuit in the shortest distance. And the introduction of cables becomes easier. In addition, by fixing a comb-shaped cable arranging support member near the cable introduction hole in the case cover, the signal cable that has been passed through the cable introduction hole can be tied in a comb shape and tied, etc. , Easy to fix. Further, a cover plate provided with an elastic member that deforms and adheres along the outer shape of the signal cable that covers the cable introduction hole and is slidably attached to the housing cover to affect natural convection inside the communication device. Since the inflow of air from the outside can be minimized, the air cooling effect can be normally maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The gist of the present invention will be described in detail below with reference to the embodiments shown in the drawings. As shown in the external perspective view of FIG. 1, the housing cover 1a of the communication device 1 connects the signal cable 3 from the software development support device 2 to the communication control circuit (not shown) provided in the communication device 1 at the shortest distance. For connection, a cable introduction hole 1a-1 is formed at a position facing the communication control circuit.

Further, as shown in the perspective view of the main part of FIG. 2, a sheet metal is cut out in the shape of a comb in the vicinity of the cable introduction hole 1a-1 (in the figure, cut into three grooves) into a right-angled L shape. Bent cable arranging support member 4 and cable introduction hole 1a
-A long hole provided in the housing cover 1a with three cut-out holes 5a covering the -1 and inserting the three signal cables 3 into each of them
A closing plate 5 which is slidably attached to the 1a-2 by screws 6; and an elastic member 7, which is attached to the inner surface of the closing plate 5 with an adhesive (not shown) and deforms and adheres along the outer shape of the signal cable 3, For example, it comprises foamed polyurethane rubber. The case cover 1a described above is intended to pass the signal cable 3 of the software development support device 2 to be connected during the operation software development period to the shortest distance. Replaced by cover.

As described above, the housing cover which is set correspondingly during the operation software development period has the cable introduction hole at the position where the signal cable is connected at the shortest distance, so that the signal cable is connected at the shortest distance and the signal delay occurs. And the introduction of cables becomes easier. Further, by providing a comb-shaped cable arranging support member in the vicinity of the cable introducing hole, it is possible to easily arrange and fix the signal cable passed through the cable introducing hole. Further, by attaching a closing plate equipped with an elastic member that deforms and adheres along the outer shape of the signal cable that covers the cable introduction hole and is slidably attached to the housing cover, the closing plate can be slid open / closed and signal Make it easy to pass the cable through the cable introduction hole, close the periphery of the passed signal cable to eliminate gaps, and minimize air inflow from the outside that affects natural convection inside the communication device and maintain normal air cooling effect. You can

In the above description, the communication device is taken as an example,
It is needless to say that the same can be applied to other electronic devices constituting the information processing system.
