Strong and weak current separated up-down structure circuit breaker

Abstract

The invention relates to a strong and weak current separation type up-down structure circuit breaker, which comprises a shell, a wire inlet terminal, a wire outlet terminal, a static contact plate, a moving contact, an electromagnetic system and an operating mechanism, side plates are arranged on the two sides of the shell, and the wire inlet terminal and the wire outlet terminal are distributed at the two ends of the shell; the wire inlet terminal is sequentially connected in series with the static contact plate, the moving contact and the electromagnetic system and then is connected in series with the wire outlet terminal to form a conductive loop; the operating mechanism controls the static contact plate and the moving contact to be separated and combined so as to achieve on-off of a conductive loop. An insulating partition plate is arranged at the bottom of the shell, a weak current bin is arranged below the insulating partition plate, a circuit board is arranged in the weak current bin, a power taking port is formed in one side of the insulating partition plate, the circuit board is provided with a power taking extension part extending upwards from the power taking port, and the power taking extension part is electrically connected with a conductive loop. The circuit board is connected with an electronic component. According to the invention, the influence of strong current on weak current is effectively avoided, and reliable guarantee is provided for the function and safety of an electronic circuit.

Description

technical field [0001] The invention relates to the field of circuit breakers, in particular to a circuit breaker with upper and lower structures separated by strong and weak electricity. Background technique [0002] Power Internet of Things and intelligent power distribution are the development trend of the current power system. The small circuit breakers used for terminal power distribution are usually modular mechanical products, which are small in size and insufficient in space, and cannot be installed with intelligent electronic components. There are two current methods. One is to add a pole or a half-pole space next to the one-pole circuit breaker to install the electronic intelligent part, and the other is to increase the volume of the one-pole circuit breaker and arrange it in the gap between the mechanical mechanism and the circuit of the one-pole circuit breaker electronic circuit.

Problems solved by technology

[0003] The two methods in the prior art have the following problems in use and product production: the product is large in size, which leads to the need to increase the space of the distribution box and increase the workload if the user wants to replace and install the smart circuit breaker under the same demand for the power circuit. Large, destroying the user's building structure and increasing costs; strong and weak current lines are mixed in a small space, the production process of the product is complicated, the production efficiency is low, and automatic assembly cannot be realized. Most of the mechanical and electronic connection methods use wires to take power. Because the wires are thin, there is a risk of disconnection after welding. The assembly process needs to be adjusted, and the wires are pulled during the assembly process, causing the wires to break through, and there is a risk of unsafety.
