Abstract
Abstract A pin jack comprised of a casing body having an insertion space for receiving a plug member. A contact assembly comprising a fixed piece, a connecting piece and a moveable contact piece assembled within the insertion space of the casing body. The members of the contact assembly are arranged laterally in the insertion space of the casing body thus reducing the overall length of the pin jack. The contact assembly can be formed from a single piece of electrically conductive material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
217 words
A pin jack for receiving an electrical plug, comprising: a casing body of insulating material having a wall defining a plug insertion space in said casing body extending along a longitudinal axis of said casing body; a stationary piece lying in a first plane and having a first lateral edge and secured to said casing body in the insertion space and extending along the longitudinal axis thereof; a substantially flat connecting piece attached to said stationary piece and extending in a second plane substantially perpendicularly therefrom within the insertion space of the casing body, said connecting piece having a projecting piece having a lateral edge which is connected to said first lateral edge wherein said projecting piece extends substantially parallel to said stationary piece; and a movable contact piece resiliently attached to said connecting piece within the insertion space of the casing body and disposed parallel to the longitudinal axis of the casing body and laterally displaced from said stationary piece and said projecting piece, such that the movable contact piece and the stationary piece are arranged transversely side by side in the insertion space of the casing body, said movable contact piece being placed in the plug insertion space such that it resiliently contacts the plug when the plug is inserted in the plug insertion space.
Claim 2
Dependent Claim
217 words
A pin jack for receiving an electrical plug, comprising: a casing body of insulating material having a wall defining a plug insertion space in said casing body extending along a longitudinal axis of said casing body; a stationary piece lying in a first plane and having a first lateral edge and secured to said casing body in the insertion space and extending along the longitudinal axis thereof; a substantially flat connecting piece attached to said stationary piece and extending in a second plane substantially perpendicularly therefrom within the insertion space of the casing body, said connecting piece having a projecting piece having a lateral edge which is connected to said first lateral edge wherein said projecting piece extends substantially parallel to said stationary piece; and a movable contact piece resiliently attached to said connecting piece within the insertion space of the casing body and disposed parallel to the longitudinal axis of the casing body and laterally displaced from said stationary piece and said projecting piece, such that the movable contact piece and the stationary piece are arranged transversely side by side in the insertion space of the casing body, said movable contact piece being placed in the plug insertion space such that it resiliently contacts the plug when the plug is inserted in the plug insertion space.
Claim 3
Dependent Claim
51 words
A pin jack according to claim 1, further comprising: a stepped portion in the wall defining the plug insertion space in the casing body; a raised engagement pawl extending outwardly from the surface of a said stationary piece, said engagement pawl positioned to engage the stepped portion of the casing body.
Claim 4
Dependent Claim
64 words
A pin jack according to claim 2, further comprising: a stationary contact piece assembled in the insertion space of the casing body, said stationary contact piece being in electrical contact with said moveable contact piece when a plug is not inserted in the plug insertion space and is disconnected from the moveable contact piece when a plug is inserted in the plug insertion space.
Claim 5
Dependent Claim
29 words
A pin jack according to claim 1, wherein the stationary piece, the connecting piece and the moveable contact piece are formed from a single piece of electrically conductive material.
Claim 6
Dependent Claim
64 words
A pin jack according to claim 1, further comprising: a stationary contact piece assembled in the insertion space of the casing body, said stationary contact piece being in electrical contact with said movable contact piece when a plug is not inserted in the plug insertion space and is disconnected from the moveable contact piece when a plug is inserted in the plug insertion space.
Claim 7
Dependent Claim
232 words
A pin jack for receiving an electrical plug, comprising: a casing body for insulating material having a wall defining a plug insertion space in said casing body extending along a longitudinal axis of said casing body; a stationary piece lying in a first plane and having a first lateral edge and secured to said casing body in the insertion space and extending along the longitudinal axis thereof, said stationary piece including a terminal extending outwardly therefrom along the longitudinal axis; a substantially flat connecting piece attached to said stationary piece and extending in a second plane substantially perpendicularly therefrom within the insertion space of the casing body, said connecting piece having a projecting piece having a lateral edge which is connected to said first lateral edge wherein said projecting piece extends substantially parallel to said stationary piece and attached thereto; a movable contact piece resiliently attached to said connecting piece within the insertion space of the casing body and disposed parallel to the longitudinal axis of the casing body and laterally displaced from said stationary piece and said projecting piece, such that the movable contact piece and the stationary piece are arranged transversely side by side in the insertion space of the casing body, said movable contact piece being placed in the plug insertion space such that it resiliently contacts the plug when the plug is inserted in the plug insertion space.
Claim 8
Dependent Claim
232 words
A pin jack for receiving an electrical plug, comprising: a casing body for insulating material having a wall defining a plug insertion space in said casing body extending along a longitudinal axis of said casing body; a stationary piece lying in a first plane and having a first lateral edge and secured to said casing body in the insertion space and extending along the longitudinal axis thereof, said stationary piece including a terminal extending outwardly therefrom along the longitudinal axis; a substantially flat connecting piece attached to said stationary piece and extending in a second plane substantially perpendicularly therefrom within the insertion space of the casing body, said connecting piece having a projecting piece having a lateral edge which is connected to said first lateral edge wherein said projecting piece extends substantially parallel to said stationary piece and attached thereto; a movable contact piece resiliently attached to said connecting piece within the insertion space of the casing body and disposed parallel to the longitudinal axis of the casing body and laterally displaced from said stationary piece and said projecting piece, such that the movable contact piece and the stationary piece are arranged transversely side by side in the insertion space of the casing body, said movable contact piece being placed in the plug insertion space such that it resiliently contacts the plug when the plug is inserted in the plug insertion space.
