Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the present distribution frame (MDF), and in particular to a protector and replacement device for protecting replacement equipment from overvoltages and overcurrents generated in communication lines due to lightning strikes and power line cross-contamination. The present invention relates to a distribution board that is integrally equipped with a terminal block for distributing and connecting external cables to equipment.

[Conventional technology]

In recent years, electronic exchanges have been rapidly promoted in order to respond to the diversification of communication services. In particular, switching equipment in digital exchanges has been made smaller by using semiconductor components throughout, contributing to a reduction in the area occupied. It is an interface device between such internal exchange equipment and external cable,
Distribute and connect thousands to tens of thousands of lines of external cables
It is desired that MDF be similarly miniaturized. Furthermore, it is desired to further shorten the facility construction period by quickly laying a huge amount of cables and installing equipment on this MDF.

An example of MDF that meets these requirements is

[Problem that the invention seeks to solve]

However, with the MDF proposed here, cables are connected within the manufacturing company between a protector unit equipped with multiple protectors and a connector block that connects jumper cables, and then the product is transported to a switching center and the front shelf of the MDF frame is installed. Since the connector block is mounted on the back side and the protector unit is individually mounted on the shelf or component on the rear side, at least two workers are required to install these devices, and the number of man-hours required for installation is reduced. It was causing an increase. In addition, all wiring to the protector unit and connector block within the manufacturing company is done by wrapping connections, and after the equipment is brought into the station, external cables and internal cables are connected to these units and blocks. Since each back surface is rotated by a rotation mechanism, the number of connection steps increases. Therefore, such
MDF inevitably lengthens the construction period for facilities, and because there is a limit to the miniaturization of the individual equipment it mounts, it also inevitably increases the area it occupies.

[Means for solving problems]

9; second, a connection between the second terminal block 110 of the first board assembly 100 and the receptacle 205 of the second board assembly 200; and third, a connection between the third terminal block 206 of the second board assembly 200. There is a connection between the receptacle 205 and the receptacle 205. In the MDF board 30, in order to reduce the number of factory wiring steps, eliminate incorrect connections, and make the board 30 smaller and thinner, a back wiring board (BWB) is used to create printed circuit patterns as much as possible. I am wiring it. In this MDF board 30, receptacle 2
05 and the second terminal block 110 can all be formed by printed circuit patterns. Wiring that cannot be formed into a printed circuit pattern is done by wrapping insulated wires around terminals that protrude from the back side of the back wiring board.

6A, 6B, and 6C show an example of a back wiring board in which wiring between the interface connector 108 and the first terminal block 109 is implemented using a printed circuit pattern. Since the MDF board 30 in this embodiment is configured to accommodate 96 lines of internal cables, it is necessary to form 192 conductor patterns (96 lines) between the interface connector 108 and the first terminal block 109. If patterns are formed on a single BWB so that these conductor patterns do not interfere with each other, a BWB with extremely large vertical and horizontal dimensions will result.
This results in an increase in the size of the board 30. To avoid this problem, as shown in Figures 6A, 6B, and 6C,
