Wire-in-slot electrical connections

Claim 2

Connecting means for forming an electrical and mechanical connection with a wire comprising: an insulating housing, a wire receiving cavity extending into said housing from one side thereof, a connecting device cavity extending into said housing from a side which is adjacent to said one side, said connecting device cavity having a flat surface and an arcuate surface, said arcuate surface being opposed to said flat surface so that said connecting device cavity has a substantially geometrically segmental cross section, said flat surface being proximate to said one side of said housing and said arcuate surface being remote from said one side, said cavities intersecting each other, an electrical connecting device comprising a plate-like member having a wire receiving end, said connecting device having an arcuate cross section and having a wire-receiving slot extending inwardly from said wire-receiving end towards its other end, the curvature of the cross-section of said connecting device conforming to the curvature of said arcuate surface of said connecting device cavity whereby, upon inserting said wire into said wire-receiving cavity and inserting said connecting device into said connecting device cavity, wire receiving end first, said wire will move relatively into said slot.

Claim 3

Connecting means as set forth in claim 1, said connecting device cavity having opposed surfaces which extend between said flat surface and said arcuate surface, whereby said connecting device cavity has a cross section in the form of a geometric segment having truncated sides, said connecting device having a thickness which is substantially equal to the width of one of said opposed surfaces whereby, after insertion of said connecting device into said connecting device cavity, the side edges of said connecting device are restrained against movement.

Claim 4

Connecting means as set forth in claim 1, said housing being of a polymeric material which is firm in thick sections and flexible in thin sections, said housing having on said one side thereof integral membrane means extending inwardly over said wire receiving cavity said membrane means being deformable inwardly of said wire receiving cavity upon insertion of said wire whereby after insertion of said wire, said membrane means forms a constrictive collar in gripping relationship to said wire.

Claim 5

Connecting means for electrically connecting two insulated wires to each other, said connecting means comprising: an insulating housing, a pair of wire-receiving cavities extending into said housing from one side thereof, said wire-receiving cavities being in side-by-side parallel relationship, a connecting device cavity extending into said housing from a side which is adjacent to said one side, said connecting device cavity having a flat surface and an arcuate surface, said arcuate surface being opposed to said flat surface so that said connecting sevice cavity has a substantially geometrically segmental cross section, said flat surface being proximate to said one side of said housing and said arcuate surface being remote from said one side, said connecting device cavity intersecting each of said pair of wire receiving cavities, an electrical connecting device comprising a plate-like member having a wire receiving end, said connecting device having an arcuate cross section and having a wire-receiving slot extending inwardly from said wire-receiving end towards its other end, the curvature of the cross-section of said connecting device conforming to the curvature of said arcuate surface of said connecting device cavity whereby, upon inserting said wires into said wire-receiving cavities and inserting said connecting device into said connecting device cavity, wire receiving end first, said wires will move relatively into said slot and the edges of said slot will penetrate the insulation of said wires and contact the conducting cores of said wires whereby said wires will be electrically connected to each other.

Claim 6

Connecting means for electrically connecting two insulated wires to each other, said connecting means comprising: an insulating housing, a pair of wire-receiving cavities extending into said housing from one side thereof, said wire-receiving cavities being in side-by-side parallel relationship, a connecting device cavity extending into said housing from a side which is adjacent to said one side, said connecting device cavity having a flat surface and an arcuate surface, said arcuate surface being opposed to said flat surface so that said connecting sevice cavity has a substantially geometrically segmental cross section, said flat surface being proximate to said one side of said housing and said arcuate surface being remote from said one side, said connecting device cavity intersecting each of said pair of wire receiving cavities, an electrical connecting device comprising a plate-like member having a wire receiving end, said connecting device having an arcuate cross section and having a wire-receiving slot extending inwardly from said wire-receiving end towards its other end, the curvature of the cross-section of said connecting device conforming to the curvature of said arcuate surface of said connecting device cavity whereby, upon inserting said wires into said wire-receiving cavities and inserting said connecting device into said connecting device cavity, wire receiving end first, said wires will move relatively into said slot and the edges of said slot will penetrate the insulation of said wires and contact the conducting cores of said wires whereby said wires will be electrically connected to each other.

Claim 7

Connecting means as set forth in claim 4, said connecting device cavity having opposed surfaces which extend between said flat surface and said arcuate surface, whereby said connecting device cavity has a cross section in the form of a geometric segment having truncated sides, said connecting device having a thickness which is substantially equal to the width of one of said opposed surfaces whereby, after insertion of said connecting device into said connecting device cavity, the side edges of said connecting device are restrained against movement.

Claim 8

Connecting means as set forth in claim 5, said housing being of a polymeric material which is firm in thick sections and flexible in thin sections, said housing having on said one side thereof integral membrane means extending inwardly over each of said wire receiving cavities, each of said membrane means being deformable inwardly of its respective wire receiving cavity upon insertion of said wires whereby, upon insertion of said wires, said membrane means is deformed inwardly of said wire-receiving cavities and forms constrictive collars in gripping relationship to said wires.

Claim 9

Connecting means as set forth in claim 5, said housing being elongated and having a plurality of pairs of said wire receiving cavities extending therein from said one side and having a plurality of spaced-apart connecting device cavities extending therein from said adjacent side, each of said connecting device cavities intersecting one of said pairs of wire-receiving cavities, said connecting device being integral with connecting sections at said other end, said connecting sections being integral with additional connecting devices which are identical to said connecting device whereby a plurality of wires, in excess of two, can be commonly connected by inserting said wires into adjacent pairs of wire-receiving openings, and inserting a plurality of connecting devices which are integral with connecting sections into the associated connecting device cavities.
