Wire splitting base

Abstract

A wire splitting base is formed by a base, an upper U-shaped cover, metal current bars and spring wiring terminals. A plurality of transverse parallel current bars are arranged on the base at intervals; the spring wiring terminals are directly fixed at two ends of the current bars; the current bars are mutually separated at intervals in an insulating way by a base body of the base; first sockets are fixed on the same position of the current bars; longitudinal grounded current bars which are separated from the transverse parallel current bars at intervals in an insulating way are arranged on the base; a plurality of second sockets are evenly fixedly on the grounded current bars at intervals; each second socket and each first socket which corresponds to the position of each transverse parallel current bars form a pairing socket; a remote signaling module which corresponds to the transverse parallel current bar is arranged in the base body; the base and the upper U-shaped cover are buckled to form a whole base body; the upper U-shaped cover is provided with a concave area; and a socket through hole which is a socket mounting hole of a lightningproof model is arranged at the bottom ofthe upper U-shaped cover.

Description

1. Technical field [0001] The invention relates to a distribution base, in particular to a lightning protection distribution base, and to an anti-vibration series-parallel multi-point spring connection low-voltage surge protector base. 2. Background technology [0002] The sub-base is a device for low-voltage power distribution. The power supply circuit is drawn from the sub-base installed in the electric control cabinet. In the field of modern process industry and railway transportation system, with the application of large-scale integration technology, the application of microelectronics in the system It has been developed by leaps and bounds, and its functions are becoming more and more powerful, but at the same time, due to the reduction of insulation, the resistance of modern electronic systems to surge impacts is significantly reduced, especially in open-air chemical systems and railway systems. This problem is particularly prominent. So from 1980, various surge protec...

AI Technical Summary

Problems solved by technology

Its shortcomings are: complex wiring, time-consuming and laborious; unable to display the status of the lightning protection device; unable to remotely signal the status of the lightning protection device; poor anti-vibration performance; limited lightning protection capability; limited number of wiring; unable to mark on the module; Parallel connection, the protection effect is easily affected by the length of the wiring. In order to better protect the system, the lightning protector must be integrated with the system

It adopts the way of direct plugging. When erected and installed, due to the weight of the lightning protection module, it is easy to loosen and cause unreliable contact, especially in vibration environments.

[0007] The disadvantages of adopting the PCB board plus spring terminal structure are: the lightning protection flow capacity is limited to below 20KA, which is limited in many practical applications and cannot meet the requirements; the lightning protection plug part has no anti-vibration design, and it is easy to loosen in long-term vibration situations. Reduce contact reliability; the module marking area is small, and the content of the wiring connection and whereabouts cannot be marked, which is inconvenient for installation and debugging; the branch line connection terminal adopts PCB board welding spring terminal to realize load current distribution, low current carrying capacity, and its electrical insulation performance It is restricted and cannot be used in plateau areas. In addition, the lightning protection module has no plug-in and guide function
