Abstract
Abstract A talk line multiple communication and test apparatus for use in conjunction with telephone central office frame equipment and comprising a housing, a face plate, and a standard type rotary switch member having a plurality of positions mounted on said face plate and said housing having at least one input and at least one output connector of the Amphenol type fixedly connected thereto and disposed therewithin, means for electrically connecting said rotary switch with respect to said input and output connectors, said input and output connectors being of the panel mount type and being adapted to receive a mating connector in mating engagement therewith, at least one input jack mounted on said face plate and means for electrically connecting said input jack to said rotary switch, and a bias connector clip member which is positionable between an interior wall of said housing and pairs of mated input and output connectors to maintain the same in mated engagement for secure and positive electrical connection, wherein said bias connector clip member comprises a substantially U-shaped member and an end cap member within which are positioned the free ends of the legs of said U-shaped member with a threaded bolt extending longitudinally through said U-shaped member to compress the legs of said U-shaped member to selectively regulate the bowing-out of said legs in order to preselect the bias force exerted upon said mated Amphenol type connectors.

Total Claims: 8
Claim 1
Independent Claim
308 words
A talk line multiple communication and test apparatus comprising a housing, a face plate, and a switch member having a plurality of selectable switching positions, means for securing said face plate with respect to said housing, said switch member being disposed within said housing, at least one input jack connected with respect to said housing, connector means comprising at least one input connector and one output connector disposed within said housing and providing a plurality of individual communication channels, means for electrically connecting said input connector to said output connector, said input and output connectors being of the multi-terminal type which are adapted to receive mating multi-terminal type connectors in mating engagement therewith, a biasing member disposed within said housing between the interior of one of the walls thereof and in abutting engagement with one of the mated connectors and exerting a biasing force thereupon to maintain said mated connectors in secure mated engagement thereby ensuring electrical connection, said biasing member having a substantially rectangular configuration including a pair of side walls and a pair of end walls, each of said end walls having an opening formed therein, at least one of said openings being internally threaded, said biasing member including a threaded bolt, said bolt being disposed within said openings in threaded engagement with said threaded one of said openings, said bolt being operable upon rotational movement thereof to vary the spacing between said end walls to thereby regulate the longitudinal axial forces imparted to said side walls to selectively regulate the spacing between said side walls, means for electrically connecting said input jack to said switch member, and means for electrically connecting said connector means to said switch member to enable said switch member to be selectively connected with one of said individual communication channels to permit communication over said selected channel via said input jack.
Claim 2
Dependent Claim
308 words
A talk line multiple communication and test apparatus comprising a housing, a face plate, and a switch member having a plurality of selectable switching positions, means for securing said face plate with respect to said housing, said switch member being disposed within said housing, at least one input jack connected with respect to said housing, connector means comprising at least one input connector and one output connector disposed within said housing and providing a plurality of individual communication channels, means for electrically connecting said input connector to said output connector, said input and output connectors being of the multi-terminal type which are adapted to receive mating multi-terminal type connectors in mating engagement therewith, a biasing member disposed within said housing between the interior of one of the walls thereof and in abutting engagement with one of the mated connectors and exerting a biasing force thereupon to maintain said mated connectors in secure mated engagement thereby ensuring electrical connection, said biasing member having a substantially rectangular configuration including a pair of side walls and a pair of end walls, each of said end walls having an opening formed therein, at least one of said openings being internally threaded, said biasing member including a threaded bolt, said bolt being disposed within said openings in threaded engagement with said threaded one of said openings, said bolt being operable upon rotational movement thereof to vary the spacing between said end walls to thereby regulate the longitudinal axial forces imparted to said side walls to selectively regulate the spacing between said side walls, means for electrically connecting said input jack to said switch member, and means for electrically connecting said connector means to said switch member to enable said switch member to be selectively connected with one of said individual communication channels to permit communication over said selected channel via said input jack.
Claim 3
Dependent Claim
98 words
A talk line multiple communication and test apparatus in accordance with claim 1, wherein said biasing member comprises a substantially U-shaped member, and an end cap member, said U-shaped member including a base portion forming one of said end walls and a pair of legs depending from said base portion, each of said legs forming one of said side walls, said end cap member having a substantially hollow rectangular configuration and forming the other of said end walls, and the ends of said legs remote from said base being positioned within the hollow of said end cap member.
Claim 4
Dependent Claim
55 words
A talk line multiple communication and test apparatus in accordance with claim 2, wherein the width of one of said legs is smaller than that of the other of said legs such that the lateral edges of one of said sidewalls is positioned inwardly of the lateral edges of the other of said side walls.
Claim 5
Dependent Claim
44 words
A talk line multiple communication and test apparatus in accordance with claim 3, wherein said remote ends of said legs of said U-shaped member are crimped inwardly towards one another, and said crimped ends being positioned within the hollow of said end cap member.
Claim 6
Dependent Claim
44 words
A talk line multiple communication and test apparatus in accordance with claim 4, wherein said switch member is of the rotary type and includes a rotary knob member, and said means for securing said face plate to said housing includes said rotary knob member.
Claim 7
Dependent Claim
60 words
A talk line multiple communication and test apparatus in accordance with claim 5, wherein said input jack includes a portion extending outwardly from said housing, said outwardly extending portion being threaded, a threaded nut, and said means for securing said face plate to said housing includes said threaded outwardly extending portion and said threaded nut disposed in threaded engagement therewith.
Claim 8
Dependent Claim
35 words
A talk line multiple communication and test apparatus in accordance with claim 6, wherein said apparatus includes a pair of input jacks, and said input jacks are connected as a single four wire input circuit.
