Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of terminal connection technology field, in particular to a kind of terminal connection that can simultaneously crimp and weld. BACKGROUND

[0002] There are many types of terminal connections in the current market, and after the terminal connection and the fastener to be fastened are fastened, the connection is usually crimped or welded. Terminal welding cable is generally soldered or ultrasonically welded, and the soldering has excellent conductivity and low material cost, but the soldering has relatively poor heat resistance and is prone to fall off or deformation in a high-temperature environment, and has low hardness and is prone to breakage of the welding point due to external pressure. Ultrasonic welding has fast welding speed and high welding strength, but the operation is difficult and requires high operating skills. Terminal crimping has simple operation and low cost, but the mechanical strength is low after crimping, and the actual contact area between the cable and the terminal is small, resulting in a large deviation between the overall current-carrying capacity and the theoretical value.
