Description

Technical Field

[0001] The utility model relates to a low-voltage and high-current socket structure. Background Art

[0002] Low-voltage motors typically use a wire-swinging structure due to their high current. If the outgoing cables experience any abnormalities during customer use, they often need to be returned to the factory for repair, which is costly and requires a wide range of customization options.

[0003] In addition, the time it takes for employees to connect the wires is long and the operation is inconvenient, resulting in high labor costs. Due to the large number of customized types, the stator code has the same parameters, different wire lengths, and different stators, which makes it difficult to standardize materials. In addition, multiple wires were originally wound together, and the winding machine could not remove the paint. Employees had to remove the paint separately and tie the lead wires, resulting in low winding efficiency. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a low-voltage, high-current socket structure that reduces the time employees spend on paralleling lines and simplifies operation, thereby reducing labor costs.

[0005] The technical solution for realizing the present utility model is as follows

[0006] A low-voltage, high-current socket structure comprises a housing, a base, and a stator core. The stator core is assembled with a frame and placed within the housing, and the base is mounted on the housing. The base is mounted on the inner side of the housing and comprises a brake line area, a tin-lined area, and mounting areas on both sides. The tin-lined area comprises four terminals evenly distributed within a first groove, and the grounding terminal among the four terminals is a spring-loaded structure.

[0007] A grounding screw is provided on a base on one side of the elastic sheet structure.

[0008] A silicone sealing layer is provided in the tin-lined area for sealing.

[0009] The spring structure includes a spring terminal and a spring; one end of the spring is connected to the center of the terminal located on the inner side of the housing, and the other end has an arc-shaped opening in the center and is in an inverted "C" shape.

[0010] The ends of the three terminals except the ground terminal located in the housing are all arc-shaped welding cup structures.

[0011] Each of the installation areas is provided with a mounting screw hole.

[0012] The exposed surface of the base is provided with a protruding shell, and the shell is externally connected with a plug.

[0013] With this technical solution, maintenance costs are reduced by simply replacing the cable plug. Furthermore, the design uses machine-assisted paint removal and needle wrapping for tinning, reducing employee time spent on line connection and simplifying operation, thereby reducing labor costs.

[0014] The integrated base must carry sufficient current. While ensuring adequate spacing and installation space, the internal grounding terminals are designed with spring clips to ensure reliable grounding. The screws are shared with the base screws. The internal power line terminals are designed with solder cups to accommodate 12-14AWG cables. Heat shrink tubing is used at the base and silicone sealing is performed. The soldered leads are connected to the corresponding UV and W phases on the PCB. BRIEF DESCRIPTION OF THE DRAWINGS
