Abstract: The present invention provides a terminal electrical connector, which includes a terminal unit and a rotating cap. The terminal unit includes a terminal unit body, one or a plurality of electrical terminals provided inside the terminal unit body, and a torsion spring positioned on the terminal unit body. A limiting groove for limiting a pivotal stroke and a first positioning groove for positioning a first end of the torsion spring are provided on an outer peripheral side of the terminal unit body. The rotating cap includes a cap body, and one or a plurality of locking blocks provided on the cap body for locking on another terminal electrical connector. A sliding block and a second positioning groove are provided on an inner circumference of the cap body. The sliding block is used for limiting the pivotal stroke of the rotating cap relative to the terminal unit body, and the torsion spring is used for inertially returning the rotating cap to a position of a reset angle relative to the terminal unit body.

Abstract: The present invention provides a piercing-through structure for a connector, comprising a hollow-core body, a lead, and a receptacle. Wherein a front connection portion is disposed at a front end of the hollow-core body; a plurality of wires extending forward is disposed at a front end of the lead disposed at a rear segment in the hollow-core body; and a plurality of metallic spikes is disposed at a front end of the connector of the receptacle and a connection sleeve movably fits around a front end of the body. So that connecting the hollow-core body and the receptacle together enables the connection sleeve of the receptacle to fit around the front connection portion of the hollow-core body, allowing the metallic spikes to pierce across surfaces of the wires such that, after piercing insulating sheaths of the wires, the metallic spikes come into contact with metallic cores of the wires, so as to achieve electrical connection of the connector of the receptacle and the wires of the hollow-core body.
