Abstract
Abstract The invention relates to a contact connection between a heating element of the coaxial type and a thicker connection pin. The connector comprises a sleeve closed by a pressure member in which a disk of soft sintered ceramic material is pulverized by moving said pressure member and is compressed as a compact mass around the bare part of the conductor projecting beyond the sheath, the end of the conductor being connected to the connection pin in a clamping connection.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
213 words
An electrical connection between a connecting pin and that part of an electrical conductor which extends within and beyond a metal sheath, the connecting pin having a larger cross-section than said conductor, comprising a sleeve supporting said sheath with its electrical conductor electrically insulated therefrom, said sleeve having a portion surrounding in spaced relation both the extending part of the electrical conductor and an end of the connecting pin, annular clamping means integrally formed with said connecting pin at said end thereof surrounded by said sleeve and being disposed in clamping engagement with said extending part of the conductor, electrically insulating material being disposed within said sleeve and filling the space around said extending part of said conductor and closely surrounding said extending part of the conductor, an axially movable pressure member received at least in part within said sleeve portion and overlying said annular clamping means and applying pressure thereon, and means mounted in relation to said pressure member for moving the latter axially relative to said sleeve and exerting pressure on said annular clamping means and electrically connecting the latter solely with said extending part of the conductor, said annular clamping means comprising an enlarged end section facilitating the connection of the larger cross-sectional connecting pin and the smaller cross-sectional conductor.
Claim 2
Dependent Claim
213 words
An electrical connection between a connecting pin and that part of an electrical conductor which extends within and beyond a metal sheath, the connecting pin having a larger cross-section than said conductor, comprising a sleeve supporting said sheath with its electrical conductor electrically insulated therefrom, said sleeve having a portion surrounding in spaced relation both the extending part of the electrical conductor and an end of the connecting pin, annular clamping means integrally formed with said connecting pin at said end thereof surrounded by said sleeve and being disposed in clamping engagement with said extending part of the conductor, electrically insulating material being disposed within said sleeve and filling the space around said extending part of said conductor and closely surrounding said extending part of the conductor, an axially movable pressure member received at least in part within said sleeve portion and overlying said annular clamping means and applying pressure thereon, and means mounted in relation to said pressure member for moving the latter axially relative to said sleeve and exerting pressure on said annular clamping means and electrically connecting the latter solely with said extending part of the conductor, said annular clamping means comprising an enlarged end section facilitating the connection of the larger cross-sectional connecting pin and the smaller cross-sectional conductor.
Claim 3
Dependent Claim
51 words
An electrical connection according to claim 1, in which said annular clamping means comprises a cylindrical enlargement on the connecting pin, said extending part of said conductor having an end portion bent in substantially perpendicular relation to said extending part and providing a surface engaged and clamped by said cylindrical enlargement.
Claim 4
Dependent Claim
24 words
An electrical connection according to claim 2, in which said end portion of the extending part of said conductor is bent into coil form.
Claim 5
Dependent Claim
57 words
An electrical connection according to claim 1, in which said annular clamping means comprises (a) a conical enlargement having an outer surface cooperating with a conical surface formed on said pressure member, the base of the conical enlargement having an axially extending slot-shaped aperture in which said extending part of the conductor is received and is clamped.
Claim 6
Dependent Claim
29 words
An electrical connection according to claim 1, in which said means for moving said pressure member comprises a nut threadedly engaging said sleeve and bearing against said pressure member.
Claim 7
Dependent Claim
41 words
An electrical connection according to claim 1, in which one of said pressure member and said sleeve is provided with an axially extending rib fitting in an axially extending groove formed in the other of said pressure member and said sleeve.
