Abstract
Abstract A conversion kit for converting to a multi-pin disconnect, a liquid tight connector of the type employed with a plastic sheathed, flexible, metallic conduit comprising a first insert body having a plurality of bores extending therethrough, a flange insert having an equal number of bores and means to fasten together the first insert body and flange insert in the connector body. Further, said kit includes a second insert body having a plurality of bores therethrough assembled to a ground cone positionable within the connector gland. Male or female pins are positioned in the various bores in any desired complementary order so that one female and one male pin unites whenever the connector body and gland are assembled. An assembly pin on the flange insert and a correspondingly shaped bore in the second insert body assure proper assembly of the body and gland.

Dependent Claim
368 words
A conversion kit for converting to a multi-pin disconnect a liquid tight connector of the type employed with plastic sheathed, flexible, metallic conduit and having a body member having a first threaded portion for insertion within the knockout of an electrical enclosure, a second threaded portion for receipt thereon in threaded engagement a gland, said body member having a bore therethrough and a bushing in said bore within said first portion, and a gland having a bore therethrough, a first end portion of said gland having internal threading to threadably engage said second threaded portion of said body member and a sealing ring in said bore of said gland at a second end portion of said gland, said kit comprising: a first insert body having first and second faces and a plurality of bores extending between said first and said second faces; a flange insert having a central hub and a circular skirt thereabout; a plurality of bores in said circular skirt equal in number and similar in location to the bores in said first insert body; fastening means for fastening said first insert body to said flange insert in said body member with said bores in said flange insert in alignment with said bores in said first insert body; a first plurality of pins, one for each bore in said flange insert, inserted in said aligned bores in said first insert body and said flange insert; a second inserT body having third and fourth faces and a plurality of bores extending between said third and fourth faces; a grounding cone having an outwardly extending thread at a first end for engaging the voids between the convolutions of a metallic conduit inserted within said sealing ring within said gland, said grounding cone having an inturned second end engaging said second insert body to retain said second insert body within said ground cone; a second plurality of pins, one for each bore in said second insert body, each of said second plurality of pins being inserted within a corresponding bore in said second insert body, said first plurality and second plurality of pins engaging when said gland is threadably engaged with said second threaded portion of said body member.
Claim 3
Dependent Claim
61 words
A conversion kit as defined in claim 1, wherein said central hub of said flange insert has a projection thereon and said second insert body has a central aperture configured to receive said central hub of said flange insert in only one axial position to align said first plurality of pins with said second plurality of pins to assure engagement thereof.
Claim 4
Dependent Claim
78 words
A conversion kit as defined in claim 1, wherein each of said bores in said circular skirt of said flange insert has a shoulder thereabout, each of said shoulders having an outside diameter smaller than the inside diameter of each of the bores in said first insert body, each of said shoulders entering an associated bore of said first insert body to align said bores of said flange insert with the corresponding bores of said first insert body.
Claim 5
Dependent Claim
39 words
A conversion kit as defined in claim 1, wherein said first insert body has an external rib about one end thereof to prevent said first insert body portion from being removed from said body member in a first direction.
Claim 6
Dependent Claim
54 words
A conversion kit as defined in claim 1, wherein said second insert body has a shoulder intermediate its ends, said shoulder engaging a corresponding shoulder on said grounding cone intermediate said first and second ends to prevent removal of said second insert body from said grounding cone in a direction towards said first end.
Claim 7
Dependent Claim
28 words
A conversion kit as defined in claim 1, wherein each of said first plurality of pins is female and each of said second plurality of pins is male.
Claim 8
Dependent Claim
83 words
A conversion kit as defined in claim 1, wherein said first plurality of pins comprises male and female pins and said second plurality of pins comprises male and female pins, a female pin being present in a corresponding bore of said second insert body for a male pin in a bore of said first insert body and a male pin being present in a corresponding bore of said second insert body for a female pin in a bore of said first insert body.
Claim 9
Dependent Claim
115 words
A conversion kit as defined in claim 1, wherein each of said bores of said first insert body has a shoulder intermediate its first and second faces and said bores of said second insert body has a shoulder intermediate its third and fourth faces; each of said first plurality of pins and second plurality of pins having a corresponding shoulder, said pin shoulder engaging said bore shoulder in said first insert body to prevent said pins from being removed from said bore in the direction of said first face and said bore shoulder in said second insert body to prevent said pins from being removed from said bore in the direction of said third face.
Claim 10
Dependent Claim
76 words
A conversion kit as defined in claim 8, wherein each of said pins has a deflectable skirt thereabout, said skirt engaging the back surface of said bore shoulders when said pins are positioned in said bores to prevent the movement of said pins in said bores of said first insert body in the direction of said second face and said pins in said bores of said second insert body in the direction of said fourth face.
