Multi-circuit integrated comprehensive connection system

Abstract

The invention discloses a multi-circuit integrated comprehensive connection system. The system comprises a total input module and a main current carrying module, wherein a total input end and a bus integration end are arranged on the total input module; the total input end is that a current input end is connected with a total switch; the bus integration end is a current output end of the total input module; the total input end is communicated with the bus integration end through a bus transition component; the bus integration end is used for connecting current output to the main current carrying module through a bus; a bus input end, a current main carrying plate and a sub wire integration output end are arranged on the main current carrying module; the bus is communicated with the bus input end; the current is introduced to the current main carrying plate through the bus input end; the sub wire integration output end is communicated with the current main carrying plate; one end of a sub wire is communicated with the sub wire integration output end; and the other end of the sub wire is connected with a sub switch. According to the invention, large-current input, integrated shunting, large-current butt-joint, standard manufacturing and mounting functions can be achieved, spaces can be saved, the standardization and consistency of products are improved, and connecting differences of electric components are reduced.

Description

technical field [0001] The invention relates to a multi-circuit integrated comprehensive connection system, which can be widely used in various installation fields such as power distribution and control. Background technique [0002] In civil, commercial, and industrial buildings, various electrical devices and complete sets of electrical equipment are widely used as tools for power transmission and distribution, such as switch boxes, distribution boxes, and distribution cabinets. Circuit breakers, miniature circuit breakers, isolating switches and other electrical components (hereinafter collectively referred to as switches). Between these switches, a large number of wires form a huge and complex connection system, and finally form a comprehensive application system of energy transmission, power distribution, safety protection, and function control with the switches, which is indispensable in the development of modern society. Important pillar! [0003] In the prior art, ...

AI Technical Summary

Problems solved by technology

Combine the heads of several wires into one big head and tin-coat it (this kind of processing technology cannot control the connection quality), so that the size of the combined head is large and uneven, and it is impossible to connect to the output end of the main switch. Part of the extra material on the head must be polished off, and there are problems with uneven and irregular grinding surfaces

The crimping surface is extremely mismatched, the crimping force exceeds the standard load, and the current distribution on the crimping surface is extremely uneven, especially chaotic. This is a very poor connection method, which is very easy to damage the crimping device and burn the crimping port; During tin construction, due to the large number of wires, uneven tin flow and virtual connections are likely to occur

[0009] The fourth type: the operation is difficult, time-consuming and labor-intensive, and it is necessary to connect the wires to the switch

[0010] The fifth type: better than the first four types, but it still needs one or two buses to connect to the sub-switch. There is a situation that the current value of the input port of this sub-switch is very large, and the crimping surface of the comb-shaped bus bar is flat. The wire is circular, and the crimping surface between the two is in point-line contact, and the current distribution is too concentrated on the extremely small crimping contact surface.

But this connection method is difficult to apply in switch boxes and distribution boxes

[0012] Therefore, the connection systems in existing electrical devices and complete sets of electrical equipment, such as switch boxes, distribution boxes, etc., have poor installability, poor safety, poor reliability, low standardization, complex processing, difficult control of human factors, and poor electrical performance. good question
