Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector. Background Art

[0002] Typically, a busbar clamp connector of a server includes two conductive terminals that contact a copper busbar.

[0003] In order to meet the functional requirement that the conductive terminals can be firmly fixed on the housing, some solutions have been described in the prior art. For example, Chinese patent number CN217545118U discloses a connector, including a main body, a first grounding terminal and a second grounding terminal connected to the main body, and a first power terminal and a second power terminal fixed inside the main body. The first power terminal and the second power terminal each have a positioning hole. The main body has a plurality of positioning protrusions that cooperate with the positioning holes. However, the combination of the positioning holes and the positioning protrusions cannot ensure that the first power terminal and the second power terminal are always firmly fixed on the main body, because the main body will deteriorate with use (for example, embrittlement caused by high temperature due to repeated use).

[0004] How to come up with a connector that can solve the above problems is one of the issues that the industry is eager to invest R&D resources to solve. Utility Model Content
