Abstract
A coaxial connector comprises a metal shell, an insulation body accommodated in the metal shell and a conductive terminal. The conductive terminal comprises a wiring portion which is exposed outside the insulation body and is used for connecting an abutting cable and a contact portion which is exposed outside the insulation body and is used for butting an abutting connector. At least two pairs of puncturing portions which are electrically contacted with the abutting cable through puncturing are formed on the wiring portion. Through designing the at least two puncturing portions, a condition that each puncturing portion only punctures an insulation layer of the cable and is not electrically contacted with a core wire is effectively reduced; simultaneously electrical contact of the conductive terminal and the cable and holding stabilization are guaranteed; and an assembling process is simple and manufacturing is easy.
