Technical Field

[0001] The utility model relates to the technical field of server connection terminals, in particular to a high-power connection terminal structure suitable for narrow spaces. Background Art

[0002] Terminals have been widely used in various product fields, such as signal terminals, connection terminals, etc. By connecting them to conductors, terminals can be used as relay components, and signals or electricity can be transmitted through them in different scenarios, thereby extending the usage length or changing the application scenario, with good practicability.

[0003] However, when used in some high-power devices, a sufficiently thick wire often needs to be connected to the rear end of the terminal to enable it to drive a high-power device through, avoiding damage to the circuit. When a thick wire is welded and installed over a short distance, it is very difficult to bend and weld, making it impossible to correctly place the terminal in position. For example, in some servers with limited space or the usage space of GPUs, it will cause the terminal to be unable to be accurately placed and used, and during subsequent assembly, the terminal needs to be corrected again, affecting the production assembly quality and production efficiency.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model

[0011] As a preference, the metal pin and the series connection plate are processed and manufactured by an integral molding technique.

[0012] As a preference, the connection plate and the series connection plate are connected together by a welding processing technique to form an electrically conductive state.
