Surface mount connector

摘要

An electrical connector includes a housing and a terminal module assembly. The terminal module assembly includes pairs of first terminal assemblies and second terminal assemblies. Each first terminal assembly comprises a first terminal block with at least one first protrusion and at least one first recess, and a plurality of first terminals securely extending through the first terminal block. Each second terminal assembly comprises a second terminal block with at least one second protrusion and at least one second recess and a plurality of second terminals securely extending through the second terminal block. The first protrusion is engaged with the second recess, the second protrusion is engaged with the first recess, and bottom surfaces of the first and second protrusions are secured in notches on the top surface of a interior wall when the terminal module assembly is received in the housing.
