Description

Technical Field

[0001] The utility model relates to a functional component, in particular to an intelligent circuit breaker functional component with electrical signal interconnection bridge structures. Background Art

[0002] With the increase in the demand for circuit breaker applications and the development of technology, there are further requirements for the functions of circuit breakers, that is, the functions of remote control, data collection and transmission are required. Generally, such devices are called intelligent circuit breakers. According to different internal structures, intelligent circuit breakers can form modules with different functions, usually including the following functional modules: circuit breaker module, communication module and power module. In specific applications, intelligent circuit breakers usually have multiple functional modules set up at the same time, which are connected to each other through electrical signals to form a group of intelligent circuit breakers (or intelligent controller) systems, and multiple intelligent circuit breakers are connected to form a system. The existing bridge device of intelligent circuit breakers usually adopts the following methods: First, the electrical connection point of the signal line of the control circuit in the intelligent circuit breaker is set with a pin hole and a contact point. The pin hole is usually set on the front of the intelligent circuit breaker facing the operator. The bridge board composed of a printed circuit board with vertical pins at both ends is used to insert the vertical pins at both ends into the pin holes of two adjacent intelligent circuit breakers from the top, bottom or front to connect their signal lines. With this connection method, when one of the intelligent circuit breakers needs to be replaced or repaired, the two adjacent intelligent circuit breakers can be separated by simply pulling out the bridge plate from the front. This is convenient for disassembly, replacement, and repair, just like traditional circuit breakers. However, it also has the defect of unreliable connection, and at the same time, it requires high precision in product manufacturing and installation, resulting in increased production costs. Another method is to set pin holes at corresponding positions on the left and right sides of the intelligent circuit breaker, and connect the pin holes of the two intelligent circuit breakers through a pin header to connect their signal lines. This method has higher connection reliability and lower requirements for product manufacturing precision. However, since all the intelligent circuit breakers in the control cabinet are arranged side by side and the left and right sides are close to the adjacent circuit breakers, when one of the intelligent circuit breakers needs to be replaced or repaired, the pin header cannot be pulled out from the front, and it needs to be disassembled one by one from both ends, so replacement and repair are very troublesome.
