Abstract

Abstract A stamped and formed connector for connecting semi-rigid conduit to electric boxes is disclosed. The subject connector is stamped from flat sheet metal stock in continuous fashion and is subsequently formed to have a conduit engaging portion and a connector box engaging portion. An end of a length of semi-rigid conduit is securely held in an aperture in the base of the connector while the connector itself can be readily mounted in an aperture of a junction box or the like.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 223 words
In combination with a semi-rigid electrical conduit having electrical wires therein and a generally round aperture in a wall portion of a junction box or the like, a one piece, self retaining, metal, conduit connector adapted to extend through said aperture and secure said conduit therein, said connector comprising: a base portion having an aperture therein into which one end of said electrical conduit extends, said aperture having radially directed slots defining a plurality of arcuate flanges therebetween, said flanges being bent with respect to said base portion to facilitate passage of said semi-rigid electrical conduit therethrough in a first direction and oppose withdrawal in the opposite direction; a plurality of sidewalls integrally extending from said base at an angle to the plane of said base, at least two of said walls being latching walls oppositely spaced and shorter than the remaining walls; latching means formed adjacent the free ends of each of said remaining walls, the free ends of said remaining walls being profiled to define an entryway having a smooth transition surface, whereby a conduit received through said aperture in the base portion of said connector and said connector is secured in said round aperture in said junction box by engagement of said latching walls on a first side and said latching means on a second side of said wall portion.
Claim 2
Dependent Claim 223 words
In combination with a semi-rigid electrical conduit having electrical wires therein and a generally round aperture in a wall portion of a junction box or the like, a one piece, self retaining, metal, conduit connector adapted to extend through said aperture and secure said conduit therein, said connector comprising: a base portion having an aperture therein into which one end of said electrical conduit extends, said aperture having radially directed slots defining a plurality of arcuate flanges therebetween, said flanges being bent with respect to said base portion to facilitate passage of said semi-rigid electrical conduit therethrough in a first direction and oppose withdrawal in the opposite direction; a plurality of sidewalls integrally extending from said base at an angle to the plane of said base, at least two of said walls being latching walls oppositely spaced and shorter than the remaining walls; latching means formed adjacent the free ends of each of said remaining walls, the free ends of said remaining walls being profiled to define an entryway having a smooth transition surface, whereby a conduit received through said aperture in the base portion of said connector and said connector is secured in said round aperture in said junction box by engagement of said latching walls on a first side and said latching means on a second side of said wall portion.
Claim 3
Dependent Claim 33 words
A one piece, self retaining, metal, electrical conduit connector in the combination according to claim 1 wherein said radial slots are out of alignment with junctures of adjacent sidewalls with said base portion.
Claim 4
Dependent Claim 32 words
A one piece, self retaining, metal, electrical conduit connector in the combination according to claim 1 wherein: said base portion has a hexagonal outer profile with sidewalls extending from each side thereof.
Claim 5
Dependent Claim 40 words
A one piece, self retaining, metal, electrical conduit connector in the combination according to claim 1 wherein: the intersections between adjacent sidewalls where they meet said base portion has a circular profile whereby tearing of said base portion is prevented.
Claim 6
Dependent Claim 220 words
A one piece, self retaining, metal, electrical conduit connector for securing a semi-rigid electrical conduit containing electrical wires into a generally round aperture in a wall portion of a junction box or the like, said connector comprising: a base portion having an aperture therein adapted to receive one end of said electrical conduit, said aperture having radially directed slots defining a plurality of arcuate flanges therebetween, said flanges being bent with respect to said base portion whereby passage of said semi-rigid electrical conduit therethrough in a first direction is facilitated and withdrawal in the opposite direction is opposed; a plurality of sidewalls integrally extending from said base and being bent with respect to the plane of said base, at least two of said walls being latching walls oppositely spaced and shorter than the remaining walls; latching means formed adjacent the free ends of each of said remaining walls; the free ends of said remaining walls being profiled to define an annular entry having a smooth transition surface, whereby said conduit is received through said aperture in the base portion of said connector and said connector is secured in said round aperture in said sidewall of said junction box by engagement of said latching walls on a first side and said latching means on a second side of said wall portion.
Claim 7
Dependent Claim 220 words
A one piece, self retaining, metal, electrical conduit connector for securing a semi-rigid electrical conduit containing electrical wires into a generally round aperture in a wall portion of a junction box or the like, said connector comprising: a base portion having an aperture therein adapted to receive one end of said electrical conduit, said aperture having radially directed slots defining a plurality of arcuate flanges therebetween, said flanges being bent with respect to said base portion whereby passage of said semi-rigid electrical conduit therethrough in a first direction is facilitated and withdrawal in the opposite direction is opposed; a plurality of sidewalls integrally extending from said base and being bent with respect to the plane of said base, at least two of said walls being latching walls oppositely spaced and shorter than the remaining walls; latching means formed adjacent the free ends of each of said remaining walls; the free ends of said remaining walls being profiled to define an annular entry having a smooth transition surface, whereby said conduit is received through said aperture in the base portion of said connector and said connector is secured in said round aperture in said sidewall of said junction box by engagement of said latching walls on a first side and said latching means on a second side of said wall portion.
Claim 8
Dependent Claim 30 words
A one piece, self retaining, metal, electrical conduit connector according to claim 5 wherein said radial slots are out of alignment with junctures of adjacent sidewalls with said base portion.
Claim 9
Dependent Claim 29 words
A one piece, self retaining, metal, electrical conduit connector according to claim 5 wherein: said base portion has a hexagonal outer profile with sidewalls extending from each side thereof.
Claim 10
Dependent Claim 37 words
A one piece, self retaining, metal, electrical conduit connector according to claim 5 wherein: the intersections between adjacent sidewalls where they meet said base portion has a circular profile whereby tearing of said base portion is prevented.
