Description

Structure and method for handling connecting cables

The present invention relates to a structure and a method for handling extra-long connecting cables which can be used in a structure connecting a main box and units whose units can be led into and out of the main box, for example, a connection terminal board and a communication device The connection structure of the units in .

Known structures of units for connecting a main box of a communication device and capable of leading in and out of the main box are disclosed, for example, in Japanese Patent Laid-Open Nos. 62-15897 and 63-62300.

Fig. 1 of the accompanying drawings shows a perspective view of a cable handling structure disclosed in Japanese Patent Laid-Open No. 62-15897. As shown in FIG. 1, the movable bases 102 are mutually movably supported on guide rails 102 fixedly installed in the main box (not shown). The movable base 102 supports the electrical device unit 101 fixed thereon and has a plurality of cables 105 protruding from its rear side, and a pair of support plates 104 are vertically installed on the rear end of the movable base 102, and the flat plate is shaken 106 is angularly and movably arranged between the support plates 104 and is supported by them, the cables 105 are arranged parallel to each other, and are fixed to the rocking plate 106 by fixing members, and the parallel cables 105 can also be fixed to the fixed plate 107, the The board can be installed in the main box behind the movable base 102 and the cable 105 can be fixed on the middle board 108 between the rocking board 106 and the fixed board 107 .

When the electrical device unit 101 is pushed into the main box, the cables 105 hang down in a U shape due to the weight of the middle plate 108, while the cables 105 remain parallel to each other and can be adjusted between the electrical device unit 101 and the main box.

However, since the cable 105 is fixed in place one by one by each fixing member, the assembly efficiency is poor and it is very time-consuming to install the cable 105; The device unit 101 is not easy to insert into the main box. In order to easily insert the electrical device unit 101 into the main box, it is necessary to increase the bending radius of the cable 105 when the electrical device unit 101 is pushed into the main box, however, this will result in the need for a large space.

Fig. 2 shows a sectional view of the cable handling structure disclosed in Japanese Patent Laid-Open No. 63-62300. As shown in Figure 2, the printed circuit board 202 is detachably installed in the device box 201, and it has the cable 205 protruding from the rear side of the printed circuit board 202, and a plurality of such device boxes 201 are vertically framed (not shown). Out), each printed circuit board 202 in the device box 201 can be connected to each other by an inter-device cable 208, which can be connected to the front side of the printed circuit board 202.

In each component box 201, there is a defined space on the printed circuit board 202 for adjusting the terminals 204 so that the cables 205 from the printed circuit board 202 can be connected thereto. The terminal 204 is slidably installed on the side frame 203 fixed on the side wall of the device box 201, the terminal 204 can slide back and forth in the direction shown by arrow B, therefore, the cable 205 has a certain super long distance, which depends on the movement of the terminal 204 distance. A connector 206 for connecting an external cable (not shown) can be connected to the front of the terminal 204. When an external cable is connected to the connector 206, the external cable can be connected to the printed circuit board 202 through the terminal 204. Cables are introduced into the device box 201 through cable holes on the side walls of the device box 201 .

After the printed circuit board 202 is installed in the device box 201, the terminal 204 can be pulled toward the front side of the device box 201, and an external cable can be connected to the connector 206; then, the terminal 204 is pushed in, and the device The inter-cable 208 is connected to the printed circuit board 202 .

In the application, only the structure shown in Fig. 2 is used, wherein the external cables and the inter-device cables 208 are connected on the front side of the device box 201, and the printed circuit board 202 cannot be put into the device box arbitrarily due to the connection of the cables 205 201 and taken out by it.

Therefore, it is an object of the present invention to provide a structure and method for handling connecting cables, which allow a unit mounted with a printed circuit board to be easily put into and taken out from a main box, wherein connecting cables can be connected, and It also allows easy positioning of the cables in the limited space between the unit and the main box.

In order to achieve the above object, the present invention provides a method for processing a connection cable, wherein the cable is composed of a plurality of wires for connecting to the inner surface of the unit main box on which the electrical device and the printed circuit board are installed. Terminals, the unit of which has a certain distance of movement to move into and out of the main box, and the connecting cable has an extra length corresponding to the distance, the method of which comprises the following steps: placing the wires horizontally parallel to the direction in which the unit moves out of the main box, and covering them with a soft layer, placing The connection cables are fitted to the terminals on the rear side of the unit and in the main box while letting the excess lengths of the connection cables hang down.

According to the present invention, there is also provided a structure for handling a connection cable, wherein the connection cable is composed of a plurality of wires for connecting to the inner surface of the rear side of the unit main box where the electrical device and the printed circuit board are installed. Terminals, the unit of which has a movement of a certain distance to move in and out of the main box, the connecting cable has an additional length corresponding to the distance. Its construction is characterized in that the conductors are arranged horizontally parallel to the direction in which the unit moves out of the main box, and covered with a soft layer, which connects the connecting cable Hold through the terminals on the rear side of the unit and in the main box, while letting the extra lengths of the connecting cables hang down.

With the above structure, the connection cable can be supported by its hanging overlong portion, and the unit can be moved in and out of the main box along with the connection cable connected to the unit and the terminal. The connection cable is stranded with a flexible layer covering the conductors and it can be easily positioned between the unit and the terminals. Since the wires are arranged horizontally parallel to the direction in which the unit moves out of the main box, and are covered with a soft layer, the connecting cables are prevented from twisting and maintain their compact shape as the unit moves in and out of the main box. Since the wires are covered with a soft layer, the connecting cables can be easily bent, allowing the unit to be moved in and out of the main box easily and without requiring a large storage space between the rear side of the unit and the terminals in the main box.

The connection cable is covered by a rubber sleeve in the area held by the unit and the rear side of the terminal in the main box, so that the connection cable can be protected by the sleeve to prevent damage, thereby preventing an external force from being applied to the When the unit and the rear side of the terminal in the main box are held on the connecting cable, the lead wires of the connecting cable are subjected to excessive compression so as to break. The connecting cable may also be covered by another rubber sleeve over the middle area between the area held by the unit in the main box and the rear side of the terminals, whereby the middle area of the connecting cable is prone to sag under the weight of the sleeve , and reliably prevents it from twisting or other confusion.

The connecting cables are supported by cable support elements which are angularly and movably installed on the rear side of the unit and the terminals in the main box respectively, since the cable support elements can be angularly moved by a certain amount according to the distance the unit moves out of the main box angle, thereby preventing the connecting cables from being subjected to undue bending even when the unit is fully pulled out of the main box by a distance corresponding to the additional length of the connecting cables.

The above and other objects, features and advantages of the present invention will be more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.
