Abstract
An adaptor or termination assembly for a mini-coax cable is made up of an extension tip which receives the inner conductor pin on the cable, a first sleeve which fits over an exposed end of the dielectric layer, and a second sleeve which surrounds an exposed end of the outer conductor, all as a preliminary to inserting the assembly into a standard sized connector body and assuring a positive connection between the cable and connector body in such a way as to avoid creating impedance which will downgrade the signal passing through the cable into the connector.
Claims23
An adapter for connecting a male end of a cable to a hollow connector body wherein the cable is of the type having inner and outer concentric electrical conductors, an annular dielectric separating said conductors, and an outer jacket of electrically non-conductive material, said inner and outer conductors having exposed portions, said adapter comprising:
- an extension member of electrically conductive material provided with a recess at one end to receive said exposed portion of said inner conductor, and longitudinal slots in surrounding relation to at least a portion of said recess and being engageable with said dielectric;
- a first sleeve of electrically non-conductive material engaging said dielectric;
- and
- a second sleeve of electrically conductive material contacting said exposed portion of said outer conductor.
In an assembly for connecting an end of a mini-coax cable to a hollow connector body wherein the cable is of the type having inner and outer concentric electrical conductors, an annular dielectric separating said conductors and an outer jacket of electrically non-conductive material, said inner and outer conductors having exposed portions and said inner conductor projecting beyond said dielectric at one end of said cable, the improvement comprising:
- an extension tip of electrically conductive material provided with a hollow end portion into which said inner conductor is inserted;
- a first sleeve of electrically non-conductive material surrounding said dielectric;
- a second sleeve of electrically conductive material in electrical contact with said exposed portion of said outer conductor;
- and
- a crimping ring disposed substantially at one end of said body and a tip-receiving retainer member axially spaced from said crimping ring.
A method of installing a coaxial cable in a hollow connector body wherein said cable has inner and outer spaced concentric electrical conductors separated by an annular dielectric and an outer insulating jacket in surrounding relation to said outer conductor, said inner conductor projecting beyond said dielectric layer at one end of said cable and said outer conductor being doubled over said jacket, the steps comprising:
- inserting said inner conductor into a recessed end of a tip;
- inserting said tip into a first sleeve composed of electrically non-conductive material until said first sleeve bears against an end of said dielectric;
- and
- inserting said tip and said first sleeve into a second sleeve having longitudinal slots therein, said second sleeve composed of an electrically conductive material and advancing said second sleeve over said first sleeve until a slotted trailing end of said second sleeve overlies said doubled-over portion of said outer conductor.
