Abstract:
1. An earphone jack comprising: a dielectric housing having a first housing portion formed with a cylindrical first plug receiving hole that extends along a first hole axis, and a second housing portion connected to said first housing portion and formed with a rectangular second plug receiving hole that extends along a second hole axis parallel to the first hole axis and that has a width along a third axis transverse to the second hole axis, said second housing portion including upper and lower wall parts at upper and lower sides of said second plug receiving hole; a conductive first contact set mounted to said first housing portion and including first, second and third resilient contacts, each of which has a resilient plug contacting portion that extends into said first plug receiving hole, wherein said plug contacting portions of any pair of said first, second and third resilient contacts form at least one of an angular distance and an axial distance therebetween with respect to the first hole axis; and a conductive second contact set mounted to said second housing portion and including a pair of first terminals and a pair of second terminals, said first terminals extending into said second plug receiving hole parallel to the second hole axis, being spaced apart from each other along the third axis, and being disposed proximate to said lower wall part of said second housing portion, said second terminals extending into said second plug receiving hole parallel to the second hole axis, being spaced apart from each other along the third axis, and being disposed proximate to said upper wall part of said second housing portion, wherein said dielectric housing further has a top side that is formed with a mounting recess, and an access hole that is formed in said first housing portion and that extends from said first plug receiving hole to said mounting recess, said earphone jack further comprising a retaining member mounted in said mounting recess and formed with a resilient tab that extends into said first plug receiving hole through said access hole.
