Abstract
Abstract The cable joining device has utility for electrically connecting the prepared ends of two opposed power cables. A female connector nest formed of metal segments which are expandable is located within a plastic housing open at respective ends. The bare copper end of the cables to be joined are each fitted with a male connector and which are respectively inserted in the connector nest for mechanically and electrically connecting the opposed power cables.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
In a cable joining device for joining the prepared ends of two opposed cables, in combination, a metal casing having end members fixedly secured thereto, an opening in each and member communicating with the interior of the metal casing, a tubular housing of insulating material located within the metal casing, each end of said housing being in spaced concentric relation therewith and being fixedly secured to the metal casing on approximately the longitudinal center of both parts, a connector having a similar shaped cavity on respective sides of its transverse centerline, and resilient means carried by the connector on each side of the centerline and performing a dual function, said resilient means rendering possible circumferential expansion of the connector, and said resilient means also locking the connector within the housing with the cavities respectively being in substantial alignment with the openings in the end members.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
146 words
A cable joining device for joining the prepared end of two opposed cables as defined in claim 1, wherein a clamping plate is fixed to each end member, a thin plastic film and an elastomeric diaphragm being interposed between each end member and the clamping plate and being clamped by said plate, said thin plastic film closing and sealing the opening in its end member until the prepared cable end is inserted, said elastomeric diaphragm having a central opening therein for receiving the prepared cable end and which has a sealing contact therewith following insertion. 3 A cable joining device for joining the prepared end of two opposed cables as defined by claim 1, wherein a female connector nest is formed of metal segments and wherein the resilient means comprise split resilient rings in encircling engagement with the connector on respective sides of its transverse centerline.
Claim 4
Dependent Claim
127 words
A cable joining device for joining the prepared end of two opposed cables as defined in claim 1 wherein a clamping plate is fixed to each end member, a thin plastic film and an elastomeric diaphragm being interposed between each end member and the clamping plate and being clamped by said plate, said thin plastic film closing and sealing the opening in its end member until the prepared cable end is inserted, said elastomeric diaphragm having a central opening therein for receiving the prepared cable end and which has a sealing contact therewith following insertion, wherein a female connector nest is formed of metal segments, and wherein the resilient means comprise split resilient rings in encircling engagement with the connector on respective sides of its transverse centerline.
Claim 5
Dependent Claim
128 words
In a cable joining device for joining the prepared ends of two opposed cables, in combination a metal casing of tubular formation having end members fixedly secured thereto, an opening in each end member communicating with the interior of the metal casing, a tubular housing of insulating material located within the metal casing, each end of said housing being in spaced concentric relation therewith and being fixedly secured to the metal casing at approximately the longitudinal center of both parts, a metal connector having a similar shaped cavity on respective sides of its transverse centerline, and means fixedly securing the connector within the housing approximately centrally of the length of the housing and with the cavities respectively being in substantial alignment with the openings in the end members.
Claim 6
Dependent Claim
128 words
In a cable joining device for joining the prepared ends of two opposed cables, in combination a metal casing of tubular formation having end members fixedly secured thereto, an opening in each end member communicating with the interior of the metal casing, a tubular housing of insulating material located within the metal casing, each end of said housing being in spaced concentric relation therewith and being fixedly secured to the metal casing at approximately the longitudinal center of both parts, a metal connector having a similar shaped cavity on respective sides of its transverse centerline, and means fixedly securing the connector within the housing approximately centrally of the length of the housing and with the cavities respectively being in substantial alignment with the openings in the end members.
Claim 7
Dependent Claim
80 words
A cable joining device for joining the prepared ends of two opposed cables as defined by claim 5, wherein a metal female connector nest is formed of angular disposed segments, and wherein the segments are retained in operative connected relation by the means fixedly securing the connector within the housing, said means comprising a pair of split resilient rings in encircling engagement with the connector, a ring being located on each side of the transverse center line of the connector.
Claim 8
Dependent Claim
98 words
A cable joining Device as defined by claim 5, for joining the prepared ends of two opposed cables, each cable comprising a copper conductor with insulator thereon, wherein the end of each cable is prepared by stripping said insulator to expose the copper conductor and wherein a male connector of metal is fitted to the bare copper end, said male connector having a shape at its terminal end which is complementary to the shape of the cavity in a female connector nest which receives the male connector upon insertion of the cable end for joining the said cables.
Claim 9
Dependent Claim
94 words
A cable joining device for joining the prepared ends of two opposed cables as defined by claim 5, additionally including a clamping plate fixed to each end member, a thin plastic film and an elastomeric diaphragm interposed between each end member and the clamping plate and being clamped by said plate, said thin plastic film closing and sealing the opening in its end member until the prepared cable end is inserted, said elastomeric diaphragm having a central opening therein for receiving the prepared cable end and which has a sealing contact therewith following insertion.
Claim 10
Dependent Claim
62 words
A cable joining device for joining the prepared ends of two opposed cables as defined by claim 8, wherein the metal casing and attached end members contain a dielectric compound which completely fills the interior of the parts, said dielectric compound being contained within the casing and end members by the thin plastic films which seal the openings in the end members.
Claim 11
Dependent Claim
95 words
A cable joining device as defined by claim 8, for joining the prepared ends of two opposed cables, each cable comprising a copper conductor with insulator thereon, wherein the end of each cable is prepared by stripping said insulator to expose the copper conductor, and wherein a male connector of metal is fitted to the bare copper end, said male connector having a shape at its terminal end which is complementary to the shape of the cavity in the connector which receives the male connector upon insertion of the cable end for joining the cables.
