Wiring block

Abstract

This invention relates to a connection block used in supply connection including an installing board with N pairs of connection posts of 0V and working voltage characterizing that the front of the board includes a front baseplate and at least one stage of upward or downward step along the side of the baseplate, when the number of the front steps is N, then each of the step is distributed with a connection post of working voltage and the front baseplate is distributed with N connection posts of 0V in displacement, which can not only keep the original routing mode but also support the mode that a supply line enters from the side by setting front steps on a front baseplate especially convenient for the access of unpliant thick cables.

Description

technical field [0001] The invention relates to a junction block, in particular to a junction block used on an ISAM (Intelligent Subscriber Access Equipment) rack. Background technique [0002] The traditional single-service DSLAM (Digital Subscriber Line Access Device), that is, ATMDSLAM (Digital Subscriber Line Access Device based on ATM protocol) or IP DSLAM (Digital Subscriber Line Access Multiplexer based on IP protocol), is now moving to multiple The evolution of service access nodes, such as 7302 ISAM FD (7302 Intelligent Subscriber Line Access Device), focuses on ensuring that multiple services are provided to all users, whether they are business users or residential users. [0003] 7302 ISAM FD access equipment has changed the previous ADSL (Asymmetric Digital Subscriber Line) access equipment. The user access density is limited by the rack and sub-rack density, so that the access capability of the system has been significantly increased. 7302 ISAM FD can not only ...

Problems solved by technology

[0006] However, if the power cord is routed from the left or right side of the installation board, it is often necessary to bend the power cord and then route it from the top and bottom of the isolation board. For a slightly thicker power cord, not only is it not easy to bend, but also Moreover, the bending angle is also difficult to control, resulting in improper arrangement of power supply wiring and affecting the safety of power supply wiring;

[0007] Second, the distance between the isolation plates set on the left and right sides of each pair of binding posts limits the space for wiring operations, so that the operating conditions are limited by many factors (for example: operating tools)
