Socket connector

The present invention relates to a connector, and more particularly to a socket connector.

Referring to the first and second figures, a conventional socket connector 100' includes an insulative housing 10', a set of lower conductive terminals 20', a set of upper conductive terminals 30' and a shield housing 40'. . The insulative housing 10' has a rectangular plate-shaped base portion 11'. The left and right sides of the base portion 11' are connected with a side wall 12'. The upper portion of the front surface of the base portion 11' protrudes forwardly with a rectangular plate-shaped abutting portion 13. '. Each of the lower conductive terminals 20 ′ has a first mounting portion 21 ′, a first holding portion 22 ′ bent downward from the rear end edge of the first mounting portion 21 ′ and a first mounting portion 21 ′ The front edge is first bent forward and downward to extend the end and then bent upward to form an arched first contact portion 23'. Each of the upper conductive terminals 30 ′ has an elongated second mounting portion 31 ′, a second holding portion 32 ′ bent downward from the rear end edge of the second mounting portion 31 ′ and a second The front end edge of the mounting portion 31' is bent downwardly and then bent forward to extend the second contact portion 33'. The first mounting portion 21' and the second mounting portion 31' of the lower conductive terminal 20' and the upper conductive terminal 30' are integrally formed in the base portion 11' and the abutting portion 13' of the insulative housing 10', and the first contact portion 23' And the second contact portion 33' protrudes from the lower surface of the abutting portion 13', and the first holding portion 22' and the second holding portion 32' protrude from the rear surface of the base portion 11'.
