Electrical connector having retention contact tails and non-retention contact tails for retaining to a PCB prior to soldering as well as reducing force of inserting the contact tails to the PCB

摘要

An electrical connector (1) includes an insulative housing (10) and a number of contacts (28) attached to the housing. The contacts each have a contact tail (36) downwardly extending beyond a mounting surface (32) of the insulative housing for inserting into throughholes (42) of a PCB (40). The contact tails are overlapped in pairs and each pair of contact tails is inserted into the same throughhole of the PCB. Some pairs of contact tails, called retention contact tails (68), have protrusions (52) deviating from each other for bearing against peripheral walls of the throughholes of the PCB thereby producing retention force. The other pairs of contact tails, called non-retention contact tails (70), do not have protrusions and do not interfere with peripheral walls of the other throughholes thereby reducing the insertion force. The retention contact tails can be modified to the non-retention contact tails by severing the protrusions therefrom.
