Apparatus for exposing core of an insulated wire

Claim 2

Apparatus for exposing the conducting core of the end portion of an insulated wire comprising: clamping and confining means for clamping said wire at a location adjacent to its end and for confining the portion of said wire between said clamping means and the end of said wire against substantial lateral flexure, insulation pushing and gathering means movable through said clamping and confining means and towards said location, said insulation pushing and gathering means having insulation engaging means engageable with said insulation on opposite sides of said wire whereby, upon movement of said insulation gathering means towards said location, the insulation of said wire is gathered away from the end of said wire and bunched between said insulation engaging means and said location thereby to expose the end portion of the conducting core of said wire.

Claim 3

Apparatus for exposing the conducting core of an insulated wire comprising: a pair of jaw members movable relatively towards and away from each other between open and closed positions, said jaw members having clamping means at one end thereof to clamp a conductor extending therebetween when said jaw members are in said closed position, and said jaw members having opposed surface portions defining a confined passageway for said wire when said jaw members are in said closed position, insulation pushing means movable through said passageway and towards said clamping means when said jaw members are closed whereby upon closure of said jaw members into surrounding relationship with a conductor with concomitant clamping of said conductor and confinement of the end portion of said conductor in said passageway, and upon movement of said insulation pushing means towards said clamping means, the insulation adjacent to the end of said wire is gathered towards said clamping means and bunched thereby to expose the end portion of the conducting core of said wire.

Claim 4

Apparatus for exposing the conducting core of an insulated wire comprising: a pair of jaw members movable relatively towards and away from each other between open and closed positions, said jaw members having clamping means at one end thereof to clamp a conductor extending therebetween when said jaw members are in said closed position, and said jaw members having opposed surface portions defining a confined passageway for said wire when said jaw members are in said closed position, insulation pushing means movable through said passageway and towards said clamping means when said jaw members are closed whereby upon closure of said jaw members into surrounding relationship with a conductor with concomitant clamping of said conductor and confinement of the end portion of said conductor in said passageway, and upon movement of said insulation pushing means towards said clamping means, the insulation adjacent to the end of said wire is gathered towards said clamping means and bunched thereby to expose the end portion of the conducting core of said wire.

Claim 5

Apparatus as set forth in claim 2 wherein said insulation pushing means comprises a pair of fingers, one of said fingers being in each of said jaw members.

Claim 6

Apparatus as set forth in claim 2 wherein said clamping means comprises a pair of clamping plates, one of said plates being mounted on each of said jaw members.

Claim 7

Apparatus as set forth in claim 2 wherein said jaw members have spaced-apart projections on said opposed surfaces, the said projections of one of said jaw members being offset with respect to the projections of the other jaw member whereby said projections interdigitate during movement of said jaw members towards each other to define said confined passageway.

Claim 8

Apparatus as set forth in claim 2 wherein said insulation pushing means comprises a pair of fingers, one of said fingers being in each of said jaw members, each finger being movably mounted in its respective jaw member for movement towards said clamping means.

Claim 9

Apparatus for exposing the conducting core of an insulated wire comprising: a pair of jaw members movable relatively towards and away from each other between open and closed positions, said jaw members having clamping means at corresponding ends thereof for clamping a conductor extending between said jaws when said jaws are in said closed position, conductor supporting and confining means on said jaw members in alignment with said clamping means, said conductor supporting means comprising supporting surfaces for supporting said conductor against substantial lateral flexure, and insulation pushing means in said jaw members, said insulation pushing means being movable relatively through said supporting and confining means and towards said clamping means whereby upon clamping of an insulated wire in said clamping means with its end portion extending into said supporting and confining means and upon movement of said insulation pushing means towards said clamping means, the end portion of the insulation of said wire is gathered towards said clamping means and the conducting core of said wire is exposed.

Claim 10

Apparatus for exposing the conducting core of an insulated wire comprising: a pair of jaw members movable relatively towards and away from each other between open and closed positions, said jaw members having clamping means at corresponding ends thereof for clamping a conductor extending between said jaws when said jaws are in said closed position, conductor supporting and confining means on said jaw members in alignment with said clamping means, said conductor supporting means comprising supporting surfaces for supporting said conductor against substantial lateral flexure, and insulation pushing means in said jaw members, said insulation pushing means being movable relatively through said supporting and confining means and towards said clamping means whereby upon clamping of an insulated wire in said clamping means with its end portion extending into said supporting and confining means and upon movement of said insulation pushing means towards said clamping means, the end portion of the insulation of said wire is gathered towards said clamping means and the conducting core of said wire is exposed.
