Abstract
Abstract An electrical connector unit has a unitary insulating housing provided with an epoxy resin wheathershed portion integrally united with an elastomeric cable-receiving portion. One embodiment utilizes a polyolefin type solvent dispersed polymer bonding agent to join the two housing portions, while a second embodiment utilizes an epoxy resin band integrally joined with the elastomeric portion during molding of the latter, and an adhesive to bond the weathershed portion to the outer surface of the band. Each embodiment utilizes a retaining ring embedded within the housing to firmly retain components of the connecting structure within the housing once connection has been effected, thereby precluding axial movement of the cable relative to the housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
An electrical connector assembly for joining the conductor of an insulated cable with the terminus of an external conductor, said assembly comprising: conductive coupling structure adapted for interengagement with said terminus and the cable conductor; and an electrical insulating housing disposed in covering relationship with said structure for protecting the latter from environmental conditions, said housing including, a substantially rigid, tubular weathershed portion at one end thereof normally adjacent said terminus and constructed of electrical insulating, thermosetting, synthetic resinous material, a flexible, tubular expansion portion at the opposide end thereof constructed of electrical insulating elastomeric material, at least partially disposed within said weathershed portion, and adapted to receive said cable; and a substantially rigid element constructed of said resinous material molded into said elastomeric portion and having an exposed outer surface, and an adhesive bonding the outer surface of said element to th rigid portion, thereby integrally uniting said rigid and elastomeric portions to produce a unitary housing wherein the rigid portion thereof exhibits insulating and track resistance properties while the elastomeric portion is sufficiently elastic to provide environmental integrity with the cable under varying temperature and weather conditions.
Claim 2
Dependent Claim
189 words
An electrical connector assembly for joining the conductor of an insulated cable with the terminus of an external conductor, said assembly comprising: conductive coupling structure adapted for interengagement with said terminus and the cable conductor; and an electrical insulating housing disposed in covering relationship with said structure for protecting the latter from environmental conditions, said housing including, a substantially rigid, tubular weathershed portion at one end thereof normally adjacent said terminus and constructed of electrical insulating, thermosetting, synthetic resinous material, a flexible, tubular expansion portion at the opposide end thereof constructed of electrical insulating elastomeric material, at least partially disposed within said weathershed portion, and adapted to receive said cable; and a substantially rigid element constructed of said resinous material molded into said elastomeric portion and having an exposed outer surface, and an adhesive bonding the outer surface of said element to th rigid portion, thereby integrally uniting said rigid and elastomeric portions to produce a unitary housing wherein the rigid portion thereof exhibits insulating and track resistance properties while the elastomeric portion is sufficiently elastic to provide environmental integrity with the cable under varying temperature and weather conditions.
Claim 3
Dependent Claim
20 words
The assembly as claimed in claim 1, wherein said element is tubular in configuration and completely surrounds said elastomeric portion.
Claim 4
Dependent Claim
16 words
The assembly as claimed in claim 1, wherein said resinous material consists of an epoxy resin.
Claim 5
Dependent Claim
19 words
The assembly as claimed in claim 1, wherein said elastomeric material consists of an ethylene propylene diene (modified) polymer.
Claim 6
Dependent Claim
74 words
The assembly as claimed in claim 1, wherein said structure includes a conductive component connected to said terminus, extending through the rigid portion, and into said elastomeric portion; a conductive link secured at one end thereof to said conductor and at the opposite end thereof to said component; and a rigid stop on said elastomeric portion clamped between the component and the link for preventing axial movement of the cable relative to the housing.
Claim 7
Dependent Claim
164 words
In a connector assembly for an electrical cable having an inner conductor, a conductive element adapted to be secured at one end thereof to the conductor and having a threaded opening in the opposite end thereof; a tubular housing, at least a portion of which is of insulating material and having a passage therein adapted to receive said element and the proximal portion of the cable in surrounding protecting relationship; a rigid, annular stop component projecting from said housing into the passage in a location abutting the conductive element; a rigid, tubular conductive core housing said conductor rod and abutting said stop component on the opposite side of said component from the conductive element; and an elongated conductor rod provided with a complementally threaded end portion and extending through said stop component, said end portion being received within said threaded opening whereby engagement of said element and said conductive core housing with the stop component precludes axial movement of the cable within the housing.
Claim 8
Dependent Claim
164 words
In a connector assembly for an electrical cable having an inner conductor, a conductive element adapted to be secured at one end thereof to the conductor and having a threaded opening in the opposite end thereof; a tubular housing, at least a portion of which is of insulating material and having a passage therein adapted to receive said element and the proximal portion of the cable in surrounding protecting relationship; a rigid, annular stop component projecting from said housing into the passage in a location abutting the conductive element; a rigid, tubular conductive core housing said conductor rod and abutting said stop component on the opposite side of said component from the conductive element; and an elongated conductor rod provided with a complementally threaded end portion and extending through said stop component, said end portion being received within said threaded opening whereby engagement of said element and said conductive core housing with the stop component precludes axial movement of the cable within the housing.
