Abstract

The invention proposes a connector, and the connector comprises a first cover body, a second cover body, and a first connection strip. The first cover body and the second cover body are fixedly connected with each other at end parts. A first cavity which can limit the movement of the first connection strip is formed between the first cover body and the second cover body. The first cavity forms a first opened end. The first connection strip is disposed in the first cavity in a sleeved manner, and the first opened end, corresponding to the first cavity, of the first connection strip is providedwith a first connection end part. The first connection end part is provided with a first fixed groove, so as to achieve the electrical connection with a transformer main circuit through a plugging connection copper bar. The connector can improve the replacement and maintenance efficiency of a power module.

Description

technical field [0001] The invention belongs to the technical field of converters, and in particular relates to a connector for conducting current between a power module and a main circuit of the converter. Background technique [0002] High-power high-voltage converters are widely used in fields such as ships, wind power, and rail transit. The internal power module is the core unit of the inverter or rectification function of the entire converter, and is often used as a whole module with the converter connected to the main circuit of the device. [0003] At present, most power modules use a low-sensitivity busbar opening and bolt fastening structure for the external main circuit interface. When the internal power module is installed in the converter, more bolts are used to connect with external copper bars or cables. [0004] However, due to the narrow installation space of the converter, it is extremely inconvenient to fasten and disassemble the bolts, especially when rep...
