Abstract
Abstract An electrical connector for attachment to the housing or frame of electrical apparatus includes a tubular electrical conductor having inner and outer ends and encircled by an insulating bushing joined to it. The conductor and bushing are separated transversely into adjoining inner and outer sections, the inner section being encircled by a flange for attachment to said housing around a hole through which the inner section extends. One of the adjoining ends of the two sections is tapered to form a conical end portion, while the other of said adjoining ends is provided with a tapered socket receiving the conical end portion. The two sections are detachably connected together under spring pressure that holds them tightly together.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A separable electrical connector for electrical apparatus having a housing, the connector having inner and outer ends and comprising a tubular electrical conductor, an insulating bushing encircling the conductor and joined thereto, the conductor and bushing being separated transversely into adjoining inner and outer sections, the inner section of the bushing being adapted to extend through a hole in a said housing and being encircled by a flange for attachment to the housing around such a hole, one of the adjoining ends of said sections being tapered to form a conical end portion in which the end surfaces of the bushing and conductor are tapered, the other of said adjoining ends being provided with a tapered socket receiving said conical end portion, the end surfaces of the bushing and conductor forming the side wall of the socket being tapered in the same direction as said conical end portion, corrosion-resistant metal plated on the opposed tapered surfaces of the tube sections in said socket, and means including a spring pressing said sections tightly together.
Claim 2
Dependent Claim
173 words
A separable electrical connector for electrical apparatus having a housing, the connector having inner and outer ends and comprising a tubular electrical conductor, an insulating bushing encircling the conductor and joined thereto, the conductor and bushing being separated transversely into adjoining inner and outer sections, the inner section of the bushing being adapted to extend through a hole in a said housing and being encircled by a flange for attachment to the housing around such a hole, one of the adjoining ends of said sections being tapered to form a conical end portion in which the end surfaces of the bushing and conductor are tapered, the other of said adjoining ends being provided with a tapered socket receiving said conical end portion, the end surfaces of the bushing and conductor forming the side wall of the socket being tapered in the same direction as said conical end portion, corrosion-resistant metal plated on the opposed tapered surfaces of the tube sections in said socket, and means including a spring pressing said sections tightly together.
Claim 3
Dependent Claim
30 words
A separable electrical connector according to claim 1, including a sealing layer of elastomeric material between the tapered surfaces of the conical end portion and socket of said insulating bushing.
Claim 4
Dependent Claim
42 words
A separable electrical connector according to claim 1, including a sealing layer of elastomeric material between the tapered surfaces of the conical end portion and socket of said insulating bushing, the inner end of said outer section being provided with said socket.
Claim 5
Dependent Claim
169 words
A separable electrical connector for electrical apparatus having a housing, the connector having inner and outer ends and comprising a tubular electrical conductor, an insulating bushing encircling the conductor and joined thereto, the conductor and bushing being separated transversely into adjoining inner and outer sections, the inner section of the bushing being adapted to extend through a hole in a said housing and being encircled by a flange for attachment to the housing around such a hole, one of the adjoining ends of said sections being tapered to form a conical end portion in which the end surfaces of the bushing and conductor are tapered, the other of said adjoining ends being provided with a tapered socket receiving said conical end portion, the end surfaces of the bushing and conductor forming the side wall of the socket being tapered in the same direction as said conical end portion, and means extending through said tubular conductor for connecting said sections, said means including a spring pressing said sections tightly together.
Claim 6
Dependent Claim
169 words
A separable electrical connector for electrical apparatus having a housing, the connector having inner and outer ends and comprising a tubular electrical conductor, an insulating bushing encircling the conductor and joined thereto, the conductor and bushing being separated transversely into adjoining inner and outer sections, the inner section of the bushing being adapted to extend through a hole in a said housing and being encircled by a flange for attachment to the housing around such a hole, one of the adjoining ends of said sections being tapered to form a conical end portion in which the end surfaces of the bushing and conductor are tapered, the other of said adjoining ends being provided with a tapered socket receiving said conical end portion, the end surfaces of the bushing and conductor forming the side wall of the socket being tapered in the same direction as said conical end portion, and means extending through said tubular conductor for connecting said sections, said means including a spring pressing said sections tightly together.
Claim 7
Dependent Claim
87 words
A separable electrical connector according to claim 4, in which said connecting means include a rod in said tube extending axially thereof, means secured to the Inner section of the tube removably holding one end of the rod therein, a rigid member secured in the outer section of the tube and provided with a central opening through which the rod extends, a head on the outer end of the rod, and resilient means compressed between said head and said rigid member and pressing said sections tightly together.
Claim 8
Dependent Claim
33 words
A separable electrical connector according to claim 5, in which said rod-holding means is a plug in the inner end of said connector, the plug being formed for attachment to an electrical conductor.
Claim 9
Dependent Claim
46 words
A separable electrical connector according to claim 5, including corrosion-resistant metal plated on the opposed tapered surfaces of the tube sections in said socket, and a sealing layer of elastomeric material between the tapered surfaces of the conical end portion and socket of said insulating bushing.
