Abstract: A piercing electrical connector includes a wire end connector. The wire end connector has a wire end body, a wire end terminal, and a wire cover engaged with the wire end body. The wire cover has a wire holding hole, and the wire end terminal has a piercing portion. The wire cover further has a clasping plate, a clasping arm and a first clasping head. The wire end body has a clasping groove, a clasping hole, a protrusion located in the clasping groove, a pre-locking groove and a locking groove that communicate with the clasping hole. When the wire end connector needs to be transported, the first clasping head extends into the pre-locking groove, and the protrusion abuts against a free end of the clasping plate so that the wire cover and the wire end body are pre-assembled together, and the piercing portion does not pierce a cable wire.

Abstract: Disclosed is a fast plug connector for use with copper wire, including an integrally-formed plastic-molded connector housing. The housing includes at least two terminal receiving slots juxtaposed inside the housing. The terminal receiving slots is embedded with engaging terminals having barbed pieces mounted at both tail ends thereof and twisted elastic sheets mounted at both head ends thereof. The upper end located at the left side and the right side of the head of the connector housing is mounted with fastening clamps, and a lower end located at the left side and the right side of the head of the connector housing is mounted with fastening holes that are respectively corresponding to the fastening clamps. The invention provides an electric connection using fast plug electrical connector that can be readily adapted for copper wires.

Abstract: A lamp connector comprises a contact and a connector body having an accommodation space accommodating the contact. The contact has a positioning hole. The connector body has a slot extending along an insertion direction of the contact and confining the contact thereinside. The accommodation space has a elastic member with a barb that corresponds to the positioning hole and has a guide slope. The contact can easily overcome elastic force of the elastic member, overpass the guide slope to go into the accommodation space and is longitudinally confined to the slot. Then, elastic force springs the barb into the positioning hole. Thus, the contact is transversely positioned in the plastic body. Thereby, the contact can be assembled to the plastic body faster, more conveniently and more firmly; the electric connection of the male plug and the female socket is more stable and more resistant to electromagnetic interference.
