Abstract
Abstract To provide a large contact area and rigid high pressure connection between a heavy power carrying terminal and a power distribution bus, capable of being thoroughly insulated with water-impervious material, a tapered or inverted frusto-conic socket is suitably machined or incised into the bus and a terminal having a similarly tapered shank is press-fitted into the socket. A clearance bore through the shank receives a bolt for connection through a receiver in the bus located beneath the conic socket. An arched washer may be used under the head of the bolt to maintain a high pressure engagement between the terminal shank and the bus during changing thermal or vibratory conditions. The entire connection area may then be jacketed with a double jacket, the jacket serving to insulate the bus and connection in a water-impervious, sealing fashion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A power distribution connection for joining two terminal members comprising an inverted, frusto-conic blind socket in one wall of a first conductive terminal member, a shank on a second terminal member, said shank including a frusto-conic section shaped and sized for press-fitting relationship within said frusto-conic socket, said socket being greater in depth than the penetration depth of said shank to allow said shank to be compressively seated within said conic socket to produce a large conic area of surface-to-surface contact between said terminal members to render said contact capable of carrying currents of over 1,000 amps., conductive means extending through said one wall of said first conductive member and the base of said frustoconic shank for permanently connecting said shank within said socket, and means for maintaining a high compressive force in said surface contact between said terminal members, wherein said permanent connecting means comprises a threaded fastener extending through the base of the frusto-conic shank of said second terminal member and a threaded receiver on the other terminal member, and further includes a biasing member maintaining relatively constant pressure between said shank and said socket.
Claim 2
Dependent Claim
187 words
A power distribution connection for joining two terminal members comprising an inverted, frusto-conic blind socket in one wall of a first conductive terminal member, a shank on a second terminal member, said shank including a frusto-conic section shaped and sized for press-fitting relationship within said frusto-conic socket, said socket being greater in depth than the penetration depth of said shank to allow said shank to be compressively seated within said conic socket to produce a large conic area of surface-to-surface contact between said terminal members to render said contact capable of carrying currents of over 1,000 amps., conductive means extending through said one wall of said first conductive member and the base of said frustoconic shank for permanently connecting said shank within said socket, and means for maintaining a high compressive force in said surface contact between said terminal members, wherein said permanent connecting means comprises a threaded fastener extending through the base of the frusto-conic shank of said second terminal member and a threaded receiver on the other terminal member, and further includes a biasing member maintaining relatively constant pressure between said shank and said socket.
Claim 3
Dependent Claim
30 words
The connection of claim 1, wherein there is a one-piece insulating cover disposed about said first terminal member, said cover being imperforate on the side opposite said second terminal member.
Claim 4
Dependent Claim
29 words
The connection of claim 1, wherein said connecting means comprises a bolt passed through said second terminal member, and a threaded member facing said socket for receiving said bolt.
