  • Patent number: 7473142
    Abstract: An audio jack includes an insulative housing (10) including a tapered, inclined rear end (13) having four sides wherein two horizontal sides are wider than the other two vertical sides, all four sides being inclined and coupled together; first, second, third, and fourth terminals (21, 22, 23, and 24) disposed in respective grooves (131, 132, 133, and 134) and each having an outer terminal (212, 222, 231, or 241) inclined and projected from the rear end (13); a plate (20) in the housing (10) served as a plug stopper; and a metal shell (30) enclosing the housing (10) and including inclined legs 32. The housing (10) further comprises two internal cavities (1311, 1321) positioning two of the first, second, third, and fourth terminals (21, 22, 23, and 24) respectively. The third and fourth terminals (23 and 24) are served as a switch upon insertion and removal of a plug (4).

  • Patent number: 7316587
    Abstract: An audio jack includes a rectangular housing including a body including a rear first compartment and a hole extended from a front face to the first compartment, and an insulate plate secured to a top of the body; a plurality of contacts provided in the housing and including first, second, third, fourth, and fifth contacts each including a flexible portion and an upright solder portion; a light emitting element provided in the first compartment and aligned with the hole and including legs inserted through the first compartment; and a shell secured onto the housing. Inserting a first plug into the hole until the contact assembly is electrically connected with the plug will effect an analog signal transmission. Inserting a second plug into the hole until its head is electrically connected with the light emitting element will effect a digital signal transmission. The plate together with the shell can provide a double shield.
