Electric connector

Abstract

The invention relates to an electric connector comprising an insulation body, two terminal module groups and a metal housing. The insulation body comprises a main body part and a plate-shaped abutted-connection part extending forward from the main body part. The abutted-connection part comprises an upper surface and a lower surface which are opposite and a front end surface and two side surfaces positioned between the upper surface and the lower surface. Each terminal module group comprises an insulation block and a row of conductive terminals fixed on the insulation block. Each conductive terminal comprises a grounding terminal and several differential signal terminals. Each conductive terminal comprises contact parts arranged on the upper surface and the lower surface. The metal housing circles around the outer sides of the terminal module groups. The electric connector is also provided with a metal shielding sheet positioned between the upper surface and the lower surface of the abutted-connection part. The shielding sheet is provided with at least one through hole and an elastic arm extending upwards or downwards in a projection mode from the inner edge of each through hole. Each insulation block is provided with at least one groove used for accommodating the elastic arm. The contacts parts of the grounding terminal are exposed outside of the groove to make contact with the elastic arm. The electric connector of the invention can reduce signal crosstalk.
