Abstract: Electrical connector which is intended for mounting on a circuit board comprises an insluating housing having a pair of mounting posts extending normally from the surface of the connector housing which is against the circuit board. Each post has a retaining portion which is adjacent to the surface of the housing, a lead-in portion, and a free end which is remote from the surface of the housing. The retaining portion comprises a semi-cylindrical portion having a retaining fin extending laterally therefrom. The fin has a first surface which extends tangentially from the cylindrical surface of the semi-cylindrical portion and a flat surface which extends from the outer edge of the fin to the flat surface of the semi-cylindrical portion. The lead-in portion of the post comprises the semi-cylindrical portion and a fin having an outer edge which slopes towards the free end of the post so that the fin has a decreasing cross-section as a distance from the housing surface increases. In use, the posts are inserted into circular holes in the circuit board and the fins are flexed and partially collapsed during insertion so that they bear against the surfaces of the holes and retain the housing on the circuit board.
