This utility model relates to the field of internal heat dissipation technology for DC charging piles, and discloses a modular high-efficiency heat dissipation DC charging pile, including a main shell, a charging gun installed in the middle of the main shell, and multiple frame mounting components inside the main shell. The power module and its electronic components are housed inside the frame mounting components, and a heat dissipation component is located in the middle of the power module and its electronic components. The heat dissipation component directly adheres to the power module and its electronic components through a heat-conducting plate, which can quickly absorb a large amount of heat generated by the core components, avoiding the problem of concentrated heat accumulation in traditional "overall heat dissipation". At the same time, multiple heat-conducting plates are added to the outside of the heat-conducting plate to further expand the heat conduction area. In addition, multiple moving wheels are installed in the wheel assembly shell of the moving component, which can drive the heat dissipation component to slide flexibly along the sliding limit plate, which is convenient for precise alignment of the power module during installation or quick removal of the heat dissipation component for cleaning during maintenance.

The invention discloses a cable resistance welding module which comprises a metal plate, a cable resistance welding spot, a tin storage groove, a chip welding area, a bus bar through groove and a plastic package body. The metal plate is arranged in the length direction, and cable resistance welding spots are arranged at the two ends of the metal plate. Two rectangular tin storage grooves are symmetrically arranged on the inner side of the cable welding spot, and a chip welding area is formed between the tin storage grooves. A through bus bar through groove is formed in the position, corresponding to the tin storage groove, of the metal plate and used for allowing a bus bar to penetrate through and completing welding together with molten tin in the tin storage groove. The tin storage tank is used for storing tin needed by chip welding and bus bar welding and providing controlled welding flux for a chip welding area in the heating process. The zoned structure between the cable welding spot and the chip welding area enables transient heat of resistance welding not to directly act on the chip welding spot, and the welding reliability is improved. The above structure is finally integrally packaged by a plastic package body, and can be used for bypass diode connection in a photovoltaic module.

This application provides a connector female socket, a connector male head, and a connector. The connector female socket includes a housing and a spring contact. The spring contact adopts an inverted U-shaped main body design, with a flexible contact structure housed within a symmetrically arranged clearance groove in the middle: including a first flexible contact extending obliquely from the top and second flexible contact parts symmetrically distributed on both sides. After the male head is inserted, three stable contact points are formed in a triangular distribution: firstly, the three-point contact design makes the current distribution more uniform, which can reduce contact resistance; secondly, the progressive contact method ensures both low insertion and extraction force and maintains sufficient contact pressure; thirdly, the triangular contact layout significantly improves vibration resistance and effectively suppresses fretting wear; finally, the interference fit fixing method of the spring contact results in a long product insertion and extraction life. This design is suitable for high-current applications in new energy vehicles, ensuring high reliability while also taking into account ease of assembly.
