Abstract
ABSTRACT
An electrical connector for terminating semi-rigid coaxial cable includes a ferrule (10) having a plurality of axially extending peripheral fingers (13) at one end, which fingers (13) are deflected inwardly into intimate contact with the outer conductor (101) of a cable (100) when the ferrule (10) is urged axially into a body member (1) having two portions (2, 3) of mutually different internal diameter with the cable (100) passing through the ferrule (10) and body member (1).

Such known methods are relati.vely diicult to carry out and clo not alwa~s pl-OVide acc~ptabl2 connections, since with the use of solder the necessary heat can damage the dialectric layer of the cabl~, and with the crimping method the ncecessary flaring o~ the outer collductor for - ir~ert:lorl o the back~up member i9 partieul arl~

Claims (5)
1. An electrical connector for terminating coaxial electrical cable of the type having a semi-rigid tubular solid outer conductor, comprising a tubular conductive body member having two axially aligned portions of mutually different internal diameter, through both of which portions the cable can pass, and a ferrule locatable within the larger internal diameter portion of the body member with the cable passing through the ferrule, the ferrule being deformable under forces applied thereto axially of the cable thereby to secure the cable within the body member with the outer conductor of the cable electrically connected to the body member, in which the ferrule comprises a tubular body portion having an outwardly directed annular flange at one end, and a plurality of axially extending fingers extending from the periphery at the other end, the arrangement being such that with the body member and ferrule mounted on a cable with the fingers on the ferrule directed towards the smaller internal diameter portion of the body member, movement of the ferrule axially along the cable with the body member held fixed relative to the cable, causes the fingers on the ferrule to be deflected inwardly on entry into the smaller diameter end portion of the body member, the fingers becoming compressed between the cable and the wall of the smaller diameter end portion of the body member and causing deformation of the outer conductor of the cable whereby an electrical connection is established between the outer conductor of the cable and the body member.
2. A connector as claimed in Claim 1, in which the larger internal diameter end portion of the body member is formed with a plurality of axially extending internal splines which bite into the tubular body portion of the ferrule on axial movement of the tubular body portion of the ferrule into the larger diameter end portion of the body member thereby to prevent relative rotary movement between the ferrule and the body member.
3. A connector as claimed in Claim 1, in which the body member has an outwardly directed annular rib intermediate its ends, and carries a coupling ring into which the body member extends, the coupling ring having and inwardly directed annular lip which is positioned between the rib on the body member and the flange on the ferrule whereby the coupling ring is secured to the body member in relatively rotatable manner.
4. A connector as claimed in claim 1, 2 or 3, in which an end portion of the centre conductor the cable is exposed to form a centre contact for the connector.
5. A connector as claimed in Claim 1, Claims 2 or Claim 3, including a centre contact member for crimping connecting to the centre conductor of the cable, and a dielectric insert locatable within the smaller internal diameter portion of the body member through which insert the centre contact member can pass.
