Abstract
Abstract A connection for coaxial cables, which provides reduced return losses and is particularly suitable for cables having corrugated outer conductors. The connection maintains the inner diameter of the outer conductor substantially constant across the joint. A ferrule having an inner sleeve which is expanded to grip the outer conductor between the inner sleeve and an outer sleeve provides good mechanical and electrical connection to the outer conductor. A central tubular member, split into opposed halves, surrounds the joint between the inner conductors and nuts screw on the ends of the tubular member to connect the ferrules to the central tubular member.

Claim 1
Independent Claim
117 words
A coaxial cable connection, said cable having an inner conductor and an outer tubular conductor, comprising: a central body member compriSing a tubular member divided longitudinally into at least two sections and positioned around a joint between the inner conductors; a ferrule having an inner sleeve and an outer sleeve, the outer sleeve positioned over the exterior of the outer conductor, the inner sleeve positioned inside the outer conductor and expanded to grip the outer conductor between the inner and outer sleeves; and a nut having a threaded portion in engagement with a threaded portion on said central body member and a flange in engagement with the ferrule to connect the ferrule and the central body member.
Claim 2
Dependent Claim
117 words
A coaxial cable connection, said cable having an inner conductor and an outer tubular conductor, comprising: a central body member compriSing a tubular member divided longitudinally into at least two sections and positioned around a joint between the inner conductors; a ferrule having an inner sleeve and an outer sleeve, the outer sleeve positioned over the exterior of the outer conductor, the inner sleeve positioned inside the outer conductor and expanded to grip the outer conductor between the inner and outer sleeves; and a nut having a threaded portion in engagement with a threaded portion on said central body member and a flange in engagement with the ferrule to connect the ferrule and the central body member.
Claim 3
Dependent Claim
162 words
A coaxial cable connection joining two coaxial cables, each cable having an inner conductor and an outer tubular conductor, comprising: a central tubular body member divided longitudinally into two opposed halves and positioned around the joint between the two inner conductors; a first ferrule attached to the end of one outer conductor and a second ferrule attached to the end of the other outer conductor, each ferrule including an inner sleeve and an outer sleeve, the outer sleeve positioned over the exterior of the related outer conductor, the inner sleeve positioned inside the related outer conductor and expanded to grip the outer conductor between inner and outer sleeves; and means in engagement with the ferrules and the opposed ends of the central member connecting the ferrules to the central member, one on each end, said means comprising nuts, a threaded portion in engagement with a threaded end portion on said central body member and a flange in engagement with the related ferrule.
Claim 4
Dependent Claim
162 words
A coaxial cable connection joining two coaxial cables, each cable having an inner conductor and an outer tubular conductor, comprising: a central tubular body member divided longitudinally into two opposed halves and positioned around the joint between the two inner conductors; a first ferrule attached to the end of one outer conductor and a second ferrule attached to the end of the other outer conductor, each ferrule including an inner sleeve and an outer sleeve, the outer sleeve positioned over the exterior of the related outer conductor, the inner sleeve positioned inside the related outer conductor and expanded to grip the outer conductor between inner and outer sleeves; and means in engagement with the ferrules and the opposed ends of the central member connecting the ferrules to the central member, one on each end, said means comprising nuts, a threaded portion in engagement with a threaded end portion on said central body member and a flange in engagement with the related ferrule.
Claim 5
Dependent Claim
15 words
A connection as claimed in claim 2, wherein said central member is a straight member.
Claim 6
Dependent Claim
21 words
A connection as claimed in claim 2, wherein said central member has two portions extending at an angle at each other.
Claim 7
Independent Claim
87 words
A method of connecting a coaxial cable having an inner conductor and an outer tubular conductor, comprising the steps of; positioning an outer sleeve on the end of the outer conductor; inserting an inner sleeve inside the end of the outer conductor; expanding the inner sleeve to grip the outer conductor between the sleeves, said sleeves forming a ferrule; positioning a central tubular member about the inner conductor; and connecting said ferrule to the central member by connecting means engaging with said ferrule and said central member.
Claim 8
Independent Claim
87 words
A method of connecting a coaxial cable having an inner conductor and an outer tubular conductor, comprising the steps of; positioning an outer sleeve on the end of the outer conductor; inserting an inner sleeve inside the end of the outer conductor; expanding the inner sleeve to grip the outer conductor between the sleeves, said sleeves forming a ferrule; positioning a central tubular member about the inner conductor; and connecting said ferrule to the central member by connecting means engaging with said ferrule and said central member.
Claim 9
Independent Claim
131 words
A method of connecting two opposed ends of coaxial cables having an inner conductor and an outer tubular conductor, comprising the steps of: cutting back the outer conductor on each cable to expose a predetermined length of inner conductor; positioning a nut on each outer conductor; positioning an outer sleeve on the end of each outer conductor; inserting an inner sleeve inside the end of each outer conductor; expanding each inner sleeve to grip the outer conductors between inner and outer sleeves, each cooperating inner and outer sleeve forming a ferrule; joining the opposed ends of the inner conductors to form a continuous conductor; positioning a central tubular member about the inner conductor; screwing the nuts onto the ends of the central member to connect the ferrules to the central member.
Claim 10
Independent Claim
131 words
A method of connecting two opposed ends of coaxial cables having an inner conductor and an outer tubular conductor, comprising the steps of: cutting back the outer conductor on each cable to expose a predetermined length of inner conductor; positioning a nut on each outer conductor; positioning an outer sleeve on the end of each outer conductor; inserting an inner sleeve inside the end of each outer conductor; expanding each inner sleeve to grip the outer conductors between inner and outer sleeves, each cooperating inner and outer sleeve forming a ferrule; joining the opposed ends of the inner conductors to form a continuous conductor; positioning a central tubular member about the inner conductor; screwing the nuts onto the ends of the central member to connect the ferrules to the central member.
Claim 11
Dependent Claim
29 words
A method as claimed in claim 6, wherein the outer conductor is of corrugated form and each inner sleeve is expanded to collapse the corrugations of the outer conductor.
Claim 12
Dependent Claim
28 words
A method as claimed in claim 6 wherein each inner sleeve is expanded to an internal diameter substantially equal to the minimum internal diameter of the outer conductor.
