Abstract
Abstract An electrical connector comprises a body defining a chamber. Electrical elements are carried by an insulating part located in said chamber. The body has an integral molded construction of resilient material and includes a generally tubular portion. An opening is provided in the end wall for an electrical cable to extend therethrough into the chamber for connection with the electrical elements. A clamp means is provided for clamping the electrical cable prior to its entry into the chamber. The clamp means comprises a clamp part and means for securing the clamp part to the insulating part. Threaded fasteners are provided which extend into threaded engagement with the clamp part. The electrical connector has means for preventing an axial compressive clamping of the body between the insulating part and the clamp part. This means comprises a portion of one of the parts for engaging the other of the parts and blocking engagement of the other of the parts with the body so that a compressive action does not occur to the body which would cause bulging thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
250 words
An electrical connector comprising a body defining a chamber having an end wall closing one end of said body, electrical elements carried by an insulating part located in said chamber, said body having an integral molded construction of resilient material and including a generally tubular portion, means defining an opening in said end wall for an electrical cable to extend therethrough into said chamber for connection with said electrical elements, said end wall having a portion defining said opening and which has a fluidtight sealing engagement with said cable, a plurality of longitudinally extending sleeve receiving openings in said end wall, clamp means for clamping said electrical cable prior to its entry into said chamber, said clamp means comprising a clamp part and means for securing said clamp part to said insulating part, said means comprising threaded fasteners which extend into threaded engagement with said clamp part, said electrical connector having means for preventing an axial compressive clamping of said body between said insulating part and said clamp part, and said means comprising a plurality of sleeves extending from one of said parts for end wall penetrating movement into said sleeve receiving openings and for engaging the other of said parts and blocking compressive engagement of the other of said parts with said body so that a compressive action does not occur to said body which would cause bulging thereof, said sleeves being of uniform cross-sectional dimension throughout their extent and being removably slidably received in said sleeve receiving openings.
Claim 2
Dependent Claim
250 words
An electrical connector comprising a body defining a chamber having an end wall closing one end of said body, electrical elements carried by an insulating part located in said chamber, said body having an integral molded construction of resilient material and including a generally tubular portion, means defining an opening in said end wall for an electrical cable to extend therethrough into said chamber for connection with said electrical elements, said end wall having a portion defining said opening and which has a fluidtight sealing engagement with said cable, a plurality of longitudinally extending sleeve receiving openings in said end wall, clamp means for clamping said electrical cable prior to its entry into said chamber, said clamp means comprising a clamp part and means for securing said clamp part to said insulating part, said means comprising threaded fasteners which extend into threaded engagement with said clamp part, said electrical connector having means for preventing an axial compressive clamping of said body between said insulating part and said clamp part, and said means comprising a plurality of sleeves extending from one of said parts for end wall penetrating movement into said sleeve receiving openings and for engaging the other of said parts and blocking compressive engagement of the other of said parts with said body so that a compressive action does not occur to said body which would cause bulging thereof, said sleeves being of uniform cross-sectional dimension throughout their extent and being removably slidably received in said sleeve receiving openings.
Claim 3
Dependent Claim
21 words
An electrical connector as defined in claim 1 wherein said sleeves and clamp part are a one-piece integrally formed plastic part.
Claim 4
Dependent Claim
19 words
An electrical connector as defined in claim 2 wherein said sleeves have openings therein for receiving said respective fasteners.
Claim 5
Dependent Claim
212 words
An electrical connector comprising, a casing defining a chamber for receiving a terminal insert, said casing having an integral molded flexible construction and including a generally tubular portion and an end wall closing one end of said tubular portion, means defining an opening in said end wall for an electrical cable to extend therethrough into said chamber for connection with the electrical elements contained in the terminal insert, said end wall having a portion defining said opening and which has a fluidtight sealing engagement with said cable, a plurality of longitudinally extending sleeve receiving openings in said end wall, a clamping attachment consisting of a clamping bracket having mounting plates projecting from an external surface of said bracket and which accommodate clamping parts which secure the electrical cable prior to its entry into said chamber, a fastening means for securing clamping parts together in clamping engagement with said cable, sleeve elements removably slidably positioned in said end wall intermediate said clamping bracket and said terminal insert and integrally molded with at least one of said bracket and said insert to prohibit any compression of said end wall of said casing thereby preventing radial expansion of the external surface of said casing, said sleeve elements being of uniform cross-sectional dimension throughout their extent.
Claim 6
Dependent Claim
212 words
An electrical connector comprising, a casing defining a chamber for receiving a terminal insert, said casing having an integral molded flexible construction and including a generally tubular portion and an end wall closing one end of said tubular portion, means defining an opening in said end wall for an electrical cable to extend therethrough into said chamber for connection with the electrical elements contained in the terminal insert, said end wall having a portion defining said opening and which has a fluidtight sealing engagement with said cable, a plurality of longitudinally extending sleeve receiving openings in said end wall, a clamping attachment consisting of a clamping bracket having mounting plates projecting from an external surface of said bracket and which accommodate clamping parts which secure the electrical cable prior to its entry into said chamber, a fastening means for securing clamping parts together in clamping engagement with said cable, sleeve elements removably slidably positioned in said end wall intermediate said clamping bracket and said terminal insert and integrally molded with at least one of said bracket and said insert to prohibit any compression of said end wall of said casing thereby preventing radial expansion of the external surface of said casing, said sleeve elements being of uniform cross-sectional dimension throughout their extent.
Claim 7
Dependent Claim
33 words
An electrical connection as defined in claim 4 wherein said elements are integrally molded to said clamping bracket and have openings for receiving fasteners for securing said clamping bracket to said terminal insert.
