Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a connection structure between a busbar trunking and a plug-in box. Background Art

[0002] The plug-in box is an important accessory in the busbar trunking system. It is connected to the busbar trunking through pins and is equipped with a molded case circuit breaker or other protection devices, such as fuses, inside for circuit breaking and protection. This design enables the plug-in box to effectively shunt the current of the busbar trunking main line to each electrical equipment, and at the same time protects each current branch through the circuit breaker or fuse inside to prevent damage due to overcurrent. Currently, the connection between the busbar trunking and the plug-in box is generally directly anchored without positioning holes, which is not convenient for installation and later disassembly and maintenance. To better solve this problem, we propose a connection structure between a busbar trunking and a plug-in box. Summary of the Invention
