Description

Technical Field

[0001] This utility model relates to a connector terminal, a connector module including the connector terminal, and a connector including the connector module. Background Technology

[0002] In the prior art, connectors typically include a housing and a terminal module disposed within the housing. The terminal module includes four terminals with different functions arranged side-by-side in a laterally oriented manner, and injection-molded bodies on the four terminals to hold them together. These four terminals are power terminals, ground terminals, return terminals, and signal terminals. In the prior art, each terminal includes an electrical contact portion at its front and an electrical connection portion at its rear. The electrical contact portion of the terminal is used for electrical contact with a busbar, and the electrical connection portion is used for electrical connection to the busbar. Due to size constraints, the lateral width of the electrical contact portion of the terminal is equal to the lateral width of the electrical connection portion, resulting in a small effective current-carrying area for the electrical contacts of the power, ground, and return terminals, limiting their current-carrying capacity. Current power, ground, and return terminals can only carry a current of 125A, which does not meet customer requirements. Furthermore, in the prior art, injection-molded bodies need to be formed on the four terminals, which leads to higher costs. Utility Model Content
