Abstract

The utility model discloses a multi-point contact low-impedance plug-in type electric connector, which is mainly composed of a plug and a socket. At least one clamping piece terminal is arranged inside the plug in a spaced way. A pin is arranged inside the socket in a way to be corresponding to each clamping piece terminal. The clamping piece terminal comprises a pair of sheet-shaped elastic arms which are arranged in an opposed way. The elastic arm ends directed towards the pin form a pair of mother clamp units. The central parts of the elastic arms are torn in the same direction to form at least one pair of son elastic arms. Each pair of son elastic arms comprises a pair of tearing ends and a pair of fixed-connection ends. Each pair of fixed-connection ends is integrally connected with the corresponding elastic arms. Each pair of tearing ends forms a pair of son clamp units. The mother clamp unit and each pair of son clamp units elastically clamp the pin. Under the same material utilization rate, the multi-point contact low-impedance plug-in type electric connector can have the contact area of the clamping piece terminal and the pin effectively increase. The number of clamping points where the clamping piece terminal clamps the pin is further increased. The contact impedance is thus lowered. The product electrical performance and the connection reliability are further enhanced.
