Description

Technical Field

[0001] This utility model relates to a terminal, including an electrical connection assembly of the terminal and a connector including the electrical connection assembly. Background Technology

[0002] In existing technology, connectors typically include a housing, terminals, and a cable. The terminals are crimped to the front end of the cable, and the terminals and cable front ends are inserted together into the housing. The terminals include crimping portions for crimping onto the cable and mating portions for mating with mating terminals of mating connectors. The crimping portions of the terminals include outer sheath crimping portions that crimp onto the cable's outer sheath and conductor crimping portions that crimp onto the exposed conductors of the cable. In existing technology, the inner surface of the outer sheath crimping portion of the terminal is a smooth surface, which results in a relatively weak holding force between the outer sheath crimping portion of the terminal and the cable's outer sheath when the terminal is crimped onto the cable, increasing the risk of the cable detaching from the terminal when the cable is pulled.
