An electric connector structure of the character referred to including a metal body with an upper elongate vertical stem portion and a lower base portion with a flat bottom; a longitudinally extending passage with longitudinally spaced radially inwardly opening channels in the stem portion, a downwardly opening internally threaded socket entering the bottom of the base portion and a counter bore between and communicating with the socket and the passage, a block of insulating material with an upper flange portion engaged and seated in the counter bore and a lower portion depending through the socket in spaced relationship from from the threads, a plurality of circumferentially spaced, elongate connector pins carried by the block and having lower portions projecting downwardly from the block and having enlarged head portions with conductor wire openings accessible at the upper end of the block, an elongate adapter ring with an externally threaded upper portion slidably engaged about the lower portion of the block and threadedly engaged in the socket and into stopped sealed engagement with the flange portion of the block and a lower, cylindrical, annular, skirt portion depending from the upper portion of the ring and the base portion of the body and through which the pins freely project, said skirt portion adapted to enter a chamber entering a flat upwardly disposed surface of a related structure opposing the bottom of the base and carrying sealing means about its exterior to seal between the skirt portion and said related structure, an elongate vertical power cable with a rubber like casing and a plurality of circumferentially spaced jacketed conductor wires extending longitudinally through the casing and having lead ends projecting from the lower end Of the casing, the lower end portion of the casing engaged in and extending longitudinally of the passage, the lead ends of the wires engaged in the wire openings in the pins and a body of potting material welded to the exterior of said lower portion of the casing and bonded with the surfaces of the passage and in the channels.
Claim 3
Dependent Claim
119 words
A structure as set forth in claim 1 wherein said base portion of the body has oppositely disposed flanges, projecting radially outwardly from the lower end of the stem portion, said flanges having upwardly, downwardly and radially outwardly opening screw fastener receiving slots with inner portions having flat vertical opposing sides and radially outwardly disposed bottoms and outer portions greater in lateral extent than the inner portions and having vertical opposing sides, said slots adapted to register with fastener receiving openings in the noted surface of the related structure and to accommodate headed screw fasteners engaged in said fastener receiving openings, whereby said fasteners are operable to urge and hold the body adjacent said surface of the related structure.
Claim 4
Dependent Claim
64 words
A structure as set forth in claim 1 wherein said block has sockets entering its upper end and in which portions of the wire jackets depending from the casing are engaged and counter bores depending from the bottom of said sockets, said pins having enlarged head portions engaged and seated in the counter bores, said wire openings entering and extending into said head portions.
Claim 5
Dependent Claim
174 words
A structure as set forth in claim 1 wherein said base portion of the body has oppositely disposed flanges projecting radially outwardly from the lower end of the stem portion, said flanges having upwardly, downwardly and radially outwardly opening screw fastener receiving slots with inner portions having flat vertical opposing sides and radially outwardly disposed bottoms and outer portions greater in lateral extent than the inner portions and having vertical opposing sides, said slots adapted to register with fastener receiving openings in the noted surface of the related structure and to accommodate headed screw fasteners engaged in said fastener receiving openings, whereby said fasteners are operable to urge and hold the body adjacent said surface of the related structure, said block having sockets entering its upper end and in which portions of the wire jackets depending from the casings are engaged and counter bores depending from the bottom of said sockets, said pins having enlarged head portions engaged and seated in the annular bores, said wire openings entering and extending into said head portions.
Claim 6
Dependent Claim
86 words
A structure as set forth in claim 1 wherein said sealing means includes a plurality of longitudinally spaced radially outwardly opening grooves in the skirt portion of the adapter ring, and O-ring seals in said grooves, the upper most O-ring occurring on the plane of the bottom of the base portion of the body to seal with and between the adapter ring, body and the structure, the other O-ring being adapted to seal with and between said skirt portion and the chamber of said related structure.
Claim 7
Dependent Claim
196 words
A structure as set forth in claim 1 wherein said base portion of the body has oppositely disposed flanges projecting radially outwardly from the lower end of the stem portion, said flanges having upwardly, downwardly and radially outwardly opening screw fastener receiving slots with inner portions having flat vertical opposing sides and radially outwardly disposed bottoms and outer portions greater in lateral extent than the inner portions and having vertical opposing sides, said slots adapter to register with fastener receiving openings in the noted surface of the related structure and to accommodate headed screw fasteners engaged in said fastener receiving openings, whereby said fasteners are operable to urge and hold the body adjacent said surface of the related structure, said sealing means includes a plurality of longitudinally spaced radially outwardly opening grooves in the skirt pOrtion of the adapter ring, and O-ring seals in said grooves, the upper most O-ring occurring on the plane of the bottom of the base portion of the body to seal with and between the adapter ring, body and the structure, the other O-ring being adapted to seal with and between said skirt portion and the chamber of said related structure.
