Abstract
Abstract A quick connection connector for a coaxial cable consists of a body having a cylindrical portion with a well therein in which a squared off end of the cable is received against a stop in the well. With cable end thus received in the well, the outer conductor or sheath of the cable is in electrical contact with the stop, and a spring-loaded pin contact in the well makes contact with the end of the cable''s center conductor. Clamp means on the connector is adapted to hold the cable end in the well.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A quick connection electrical connector for testing of coaxial cable which has a center conductor supported within a tubular sheath, said connector comprising a body having a cylindrical portion with a well therein in which a cable end having its center conductor and tubular sheath cutoff in a single plane at right angles to the axis of the cable is received, stop means in the well against which said cable end abuts, a spring loaded electrically conductive pin supported in the body having a fRee end extending into the well to resiliently contact the end of said center conductor which is exposed at said cable end, first conducting means by which the pin is supported and to which the pin is electrically connected, a center cavity in the body beyond the stop means, the first conducting means extending through the body including the cavity therein, and being electrically insulated from the body, and releasable clamp means for temporarily holding a cable end in said well.
Claim 2
Dependent Claim
165 words
A quick connection electrical connector for testing of coaxial cable which has a center conductor supported within a tubular sheath, said connector comprising a body having a cylindrical portion with a well therein in which a cable end having its center conductor and tubular sheath cutoff in a single plane at right angles to the axis of the cable is received, stop means in the well against which said cable end abuts, a spring loaded electrically conductive pin supported in the body having a fRee end extending into the well to resiliently contact the end of said center conductor which is exposed at said cable end, first conducting means by which the pin is supported and to which the pin is electrically connected, a center cavity in the body beyond the stop means, the first conducting means extending through the body including the cavity therein, and being electrically insulated from the body, and releasable clamp means for temporarily holding a cable end in said well.
Claim 3
Dependent Claim
128 words
The connector of claim 1 for a coaxial cable of which the sheath is made of conductive material to provide an outer conductor, the outside diameter of the pin support and the inside diameter of the center cavity in the body being proportioned to provide the correct electrical impedance to match the impedance of the cables to be tested, said body including second conducting means, said cylindrical portion of the body being conductive and connected to said second conducting means, and said stop means in said well being an annular shoulder of conductive material integral with said cylindrical portion, and in position for the sheath at said cable end in the well to abut it and thereby complete a conductive path from said sheath to second conducting means.
Claim 4
Dependent Claim
110 words
The connector of claim 2 in which said spring-loaded pin is approximately the same diameter as said center conductor of the cable and is supported to contact the end of said center conductor substantially in end to end axial alignment when said cable end is in the well and against said annular shoulder, and in which the radial distance from the pin to the shoulder is approximately the same as the radial distance from the center conductor to the sheath, whereby said pin and said cylindrical portion provide a continuous transmission path to said conducting means, which path is thereby dimensionally adapted to maintain the impedance characteristics of the cable.
Claim 5
Dependent Claim
120 words
The connector of claim 1 in which said clamp means comprises a sleeve having a bore therethrough through which the cable is normally slidably received, said sleeve and said cylindrical portion being adapted for one end of the sleeve to be screwed onto the cylindrical portion, a member mounted in the sleeve adjacent to the bore for movement laterally into the bore to bear against the sheath of a cable through the bore, and cam means in the sleeve actuated by movement of the cylindrical portion into the sleeve when the sleeve is screwed onto the cylindrical portion for moving the member into the bore and thereby holding a cable which is through the sleeve in fixed position relative thereto.
Claim 6
Dependent Claim
100 words
The connector of claim 4 for a coaxial cable of which the sheath is made of conductive material to provide an outer conductor, said connector including second conducting means through the body, said member being of conductive material, said cylindrical portion of the body being conductive and connected to said second conducting means, and means completing an electrical connection between the member and the cylindrical portion when the sleeve is screwed onto the cylindrical portion, thereby to provide a conductive path from said sheath to said second conducting means when said cable is fixed through the sleeve by said member.
Claim 7
Dependent Claim
48 words
The connector of claim 1 in which said body has the center cavity opening into said well, in which said pin is slidably mounted in a tube that is the support for said pin, and including a spring in the tube urging said pin outward into said well.
Claim 8
Dependent Claim
43 words
The connector of claim 6 in which the inside diameter of said center cavity and the outside diameter of said tube are proportioned to provide electrical impedance matching the electrical impedance characteristics of a cable that is to be connected to the connector.
