Abstract
Abstract An electrical jack suitable for direct connection to a printed circuit board which has an elongated nonconductive housing with a cylindrical opening for insertion of a plug and at least two wrap-around contact assemblies extending generally transverse to the cylindrical opening. Each contact assembly including a first cantilevered contact member having a free end movable between a first and second position in response to insertion and removal of the plug. Each contact assembly further includes a second cantilevered contact member having a free end adapted for electrical engagement with the free end of the first contact member. The respective contact portions of the free ends of the first and second contact members are disposed at an angle with respect to the direction of movement of the contact portions into and out of electrical engagement with each other to increase the wiping action therebetween.

Claim 1
Independent Claim
247 words
An electrical jack suitable for direct connection to a printed circuit board comprising: an elongated nonconductive housing having a generally cylindrical opening therein along a longitudinal axis for insertion of a plug member; at least two contact assemblies mounted in said housing extending generally transverse to said cylindrical opening, each of said contact assemblies including a first contact element mounted in a cantilevered manner in said housing and having a portion extending transversely across said cylindrical opening for electrical engagement with a portion of said plug member when inserted therein, said first contact element further including a free end movable between a first and second position in response to insertion and removal of said plug member, respectively, a second contact element mounted in a cantilevered manner in said housing and having a free end, each of the free ends of said first and second contact elements including contact surfaces for electrical engagement with each other when the free end of said first contact element is in its second position, the contact surface of said second contact element being disposed at an angle of at least about 10°-15° but less than about 75°-80° relative to the generally linear movement of the free end of said first contact element between said first and second positions, means for retaining said first and second contact elements in said housing, and means electrically connected with each of said first and second contact elements for direct electrical connection with a printed circuit board.
Claim 2
Dependent Claim
247 words
An electrical jack suitable for direct connection to a printed circuit board comprising: an elongated nonconductive housing having a generally cylindrical opening therein along a longitudinal axis for insertion of a plug member; at least two contact assemblies mounted in said housing extending generally transverse to said cylindrical opening, each of said contact assemblies including a first contact element mounted in a cantilevered manner in said housing and having a portion extending transversely across said cylindrical opening for electrical engagement with a portion of said plug member when inserted therein, said first contact element further including a free end movable between a first and second position in response to insertion and removal of said plug member, respectively, a second contact element mounted in a cantilevered manner in said housing and having a free end, each of the free ends of said first and second contact elements including contact surfaces for electrical engagement with each other when the free end of said first contact element is in its second position, the contact surface of said second contact element being disposed at an angle of at least about 10°-15° but less than about 75°-80° relative to the generally linear movement of the free end of said first contact element between said first and second positions, means for retaining said first and second contact elements in said housing, and means electrically connected with each of said first and second contact elements for direct electrical connection with a printed circuit board.
Claim 3
Dependent Claim
42 words
