  • Patent number: 7371125
    Abstract: A miniature audio jack connector (100) for electrically connecting a mating plug (200) includes an arched insulative housing (1), a number of conductive contacts (2) retained in the housing (1) and a pair of switch contacts (3) containing a movable contact (31) and an immovable contact (32). The housing defines a top wall (13), a plug-insertion hole (16) and an opening (134) through the top wall. The movable contact defines an elastic arm (312) with an emboss (313) extending into the plug-insertion hole and a mating portion for connecting with the immovable contact. The arm (312) is movable within the opening (134), thereby minimizing the profile of the insulative housing (1).

  • Patent number: 7341491
    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.

  • Publication number: 20070218774
    Abstract: An audio jack (100) for electrically connecting a mating plug (200) includes an insulative housing (10) and a number of electrical contacts (21, 22, 23, 24) retained therein. The insulative housing (10) has a first sidewall (11), a second sidewall (12) opposite to the first sidewall, and a plug-insertion hole (15) extending in a longitudinal direction thereof. Each electrical contact (21, 22, 23, 24) includes a mating portion (212, 222, 232, 242), a retaining portion (211, 221, 231, 241) and a solder portion (213, 223, 233, 243). The retaining portions (211, 221, 231, 241) are engaged with the first sidewall (11). The mating portion (212, 222, 232, 242) and the retaining portion (211, 221, 231, 241) of the electrical contacts (21, 22, 23, 24) are located on the same side of the insulative housing (10).
