Abstract
Abstract An electrical jack module comprising a vertically stacked series of electrical jacks having respective housings provided with respective open-ended axial bores wherein an electrical jack plug may be inserted for interference engagement with a protruding portion of a moveable contact member biased resiliently into electrical engagement with a fixed contact member disposed in grooves in the longitudinal side surfaces of the housings. A pair of the fixed contact members comprise integral end portions of a pre-shaped shunt wire press-fitted into plurality of communicating grooves provided in aligned side surfaces of adjacent housings in the vertically stacked series. The moveable contact members are integrally connected through respective preshaped spring wires disposed in grooves in the sides surfaces of the housing to respective wire terminals protruding in a common array from a proximal supporting surface of the vertically stacked series of housings. The vertically stacked series of housings also has an opposing distal surfaces provided with a plurality of mutually spaced protrusions which constitute a restraining means for restricting movement of the electrical jack module.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
An electrical jack assembly comprising: a first electrical switch having a pair of contacts, one thereof being engageable by a jack plug and electrically connected to a terminal end portion of the first electrical switch extending beyond a bottom portion of the first switch; a second electrical switch having a bottom portion disposed over the first electrical switch and having a pair of contacts, one thereof being engageable by a jack plug and electrically connected to a terminal end portion of the second electrical switch extending beyond the bottom portion of the first electrical switch; and electrical shunt means integrally joined to the respective other ones of the pairs of contacts of the first and second electrical switches for electrically connecting said other ones of the pairs of contacts to one another directly in said assembly.
Claim 2
Dependent Claim
136 words
An electrical jack assembly comprising: a first electrical switch having a pair of contacts, one thereof being engageable by a jack plug and electrically connected to a terminal end portion of the first electrical switch extending beyond a bottom portion of the first switch; a second electrical switch having a bottom portion disposed over the first electrical switch and having a pair of contacts, one thereof being engageable by a jack plug and electrically connected to a terminal end portion of the second electrical switch extending beyond the bottom portion of the first electrical switch; and electrical shunt means integrally joined to the respective other ones of the pairs of contacts of the first and second electrical switches for electrically connecting said other ones of the pairs of contacts to one another directly in said assembly.
Claim 3
Dependent Claim
39 words
An electrical jack assembly as set forth in claim 1 wherein the contacts of the first and second electrical switches are wires, said one of the contacts of each pair and the respective terminal end portion being integrally formed.
Claim 4
Dependent Claim
35 words
An electrical jack assembly as set forth in claim 2 wherein the shunt means comprises a wire integrally formed with said other ones of the pairs of contacts of the first and second electrical switches.
Claim 5
Dependent Claim
200 words
A switch assembly comprising: (a) a first electrical jack having a cavity disposed along an axis for receiving a jack plug and comprising a plurality of electrical switches disposed along the axis, each switch comprising a pair of electrical contacts, one of said contacts in each pair thereof being engaged by a received jack plug for actuating said switch and having a terminating end portion protruding beyond a bottom wall of said first electrical jack; (b) a second electrical jack disposed above the first electrical jack and having a cavity disposed along an axis for receiving a jack plug, said second electrical jack comprising a plurality of electrical switches disposed along said axis, each switch comprising a pair of electrical contacts, one of said contacts of each pair thereof being engaged by a received jack plug for actuating said switch and having a terminating end portion extending beyond a bottom wall of the second electrical jack and protruding beyond the bottom wall of the first electrical jack; and electrical shunt means integrally joined to other ones of said pairs of contacts of said first electrical jack and to other ones of said pairs of contacts of said second electrical jack.
Claim 6
Dependent Claim
200 words
A switch assembly comprising: (a) a first electrical jack having a cavity disposed along an axis for receiving a jack plug and comprising a plurality of electrical switches disposed along the axis, each switch comprising a pair of electrical contacts, one of said contacts in each pair thereof being engaged by a received jack plug for actuating said switch and having a terminating end portion protruding beyond a bottom wall of said first electrical jack; (b) a second electrical jack disposed above the first electrical jack and having a cavity disposed along an axis for receiving a jack plug, said second electrical jack comprising a plurality of electrical switches disposed along said axis, each switch comprising a pair of electrical contacts, one of said contacts of each pair thereof being engaged by a received jack plug for actuating said switch and having a terminating end portion extending beyond a bottom wall of the second electrical jack and protruding beyond the bottom wall of the first electrical jack; and electrical shunt means integrally joined to other ones of said pairs of contacts of said first electrical jack and to other ones of said pairs of contacts of said second electrical jack.
Claim 7
Dependent Claim
40 words
