ABSTRACT:
A miniature audio jack connector (100) for electrically connecting a mating plug (5) includes an insulative housing (1), a number of contacts (2) retained in the housing. The housing defines a plug-insertion hole (12) in a longitudinal direction thereof. The contacts include a second contact (22) and a third contact (23). The second contact includes a second retaining portion (220) and a second elastic arm (221) extending into the plug-insertion hole. The third contact includes a third retaining portion (230) and a third elastic arm (231) extending opposite to the second elastic arm. The second and third retaining portions (220, 230) overlap each other along the longitudinal direction of the housing (1), thereby lengthening the elastic arms (221, 231) of the contacts (22, 23) to be reliable connecting with the mating plug.
