Description

Technical Field

[0001] The utility model belongs to the field of electronic connection accessories, in particular to an automobile battery connector with an aluminum wire connection function. Background Art

[0002] Automobile batteries need to be connected through connectors when in use. Battery connectors have also evolved into various types and shapes due to connection requirements and installation space limitations. However, conventional battery connectors still have certain limitations in that they are fixed to terminal posts to achieve connection between electrical components.

[0003] The utility model designs an automobile battery connector with an aluminum wire connection function to solve the above problems. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A car battery connector with an aluminum wire connection function comprises a copper connector body and a crimped aluminum tube. A welding plate is provided on the surface of the connector body. The crimped aluminum tube is welded to the welding plate by friction welding. An opening is provided on the side of the connector body and a locking assembly is installed at the opening.

[0006] As a preferred solution, the locking assembly includes a bolt and a nut, and two fastening plates are symmetrically arranged at the opening of the joint body, with a gap left between the two fastening plates. The bolt passes through the two fastening plates and the head extends to the lower side of the fastening plate. The nut is connected to the bolt and is located on the upper side of the fastening plate, and a gasket is placed between the nut and the fastening plate.

[0007] As a preferred solution, a groove is provided at the outer end of the bottom of the fastening plate, a straight rod is provided at the head of the bolt and is located on the lower side of the fastening plate, and limiting blocks are provided at both ends of the straight rod, and the upper end of the limiting block extends into the adjacent groove on the upper side and abuts against the inner wall of the groove.

[0008] Compared with the existing technology, the advantages of the utility model are:

[0009] 1. The crimped aluminum tube designed in the utility model is connected to the joint body by friction welding. Compared with other copper-aluminum connection methods such as crimping and resistance welding, it has the advantage of smaller connection resistance and can be used as a connector between electrical parts that require a larger current-carrying area. Friction welding has a safe and stable connection and fixing effect. In addition, this product can provide the basic function of aluminum wire crimping while maintaining a stable connection between the connection body and the car battery, effectively reducing the cost of vehicle manufacturing.

[0010] 2. The locking assembly designed by the utility model adopts a bolt locking piece to ensure the stability of the connection between the connector body and the battery connector, and its compact structure facilitates personnel to disassemble and adjust the product near the car battery in a narrow space.
