Abstract
Abstract A connector and cable preparation fixture to provide a coaxial cable tap while the cable continues to pass signals. The apparatus of the present invention attaches the cable tap without shorting the conductors and without significantly changing the coaxial cable parameters which would affect the data flow therein. The fixture described herein provides a guide for a cutting operation and for the subsequent assembly of the finished connector. The connector includes a cable tap which mounts on the coaxial cable in a perpendicular manner, and a center pin which attaches to the coaxial cable center wire along the axis of the cable tap. The center pin has two prongs spaced apart in opposition to straddle the center conductor. The connector is easily installed with no measurements. The resulting connection has a long and reliable life without causing an interruption to information or signal flow on the cable at any time.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
82 words
A fixturing apparatus securing a coaxial cable having an inner conductor and a concentric shield, comprising: means to position the coaxial cable in the fixture including a removable shoe having a longitudinal recess to partially surround the cable along the axis thereof to secure and support the cable within said means to postion; and means to selectively remove portions of the coaxial cable, wherein said shoe is positioned in relation to the cable opposite to the removed portion of the coaxial cable.
Claim 2
Dependent Claim
82 words
A fixturing apparatus securing a coaxial cable having an inner conductor and a concentric shield, comprising: means to position the coaxial cable in the fixture including a removable shoe having a longitudinal recess to partially surround the cable along the axis thereof to secure and support the cable within said means to postion; and means to selectively remove portions of the coaxial cable, wherein said shoe is positioned in relation to the cable opposite to the removed portion of the coaxial cable.
Claim 3
Dependent Claim
20 words
The fixturing means of claim 1 wherein said means to selectively remove portions removes a portion of the shield element.
Claim 4
Dependent Claim
26 words
The fixturing means of claim 2 wherein said means to selectively remove includes an axis which is laterally offset from the axis of the coaxial cable.
Claim 5
Dependent Claim
19 words
The fixturing means of claim 3 wherein said means to selectively remove includes means to cut the coaxial cable.
Claim 6
Dependent Claim
24 words

Claim 8
Dependent Claim
49 words
A coaxial cable fixturing apparatus securing a coaxial cable including a shield and having a selectively removed portion forming an aperture through the coaxial cable shield, comprising: means to position the cable in the fixture; and a removable shoe to support said coaxial cable radially opposite to said aperture.
Claim 9
Dependent Claim
49 words
A coaxial cable fixturing apparatus securing a coaxial cable including a shield and having a selectively removed portion forming an aperture through the coaxial cable shield, comprising: means to position the cable in the fixture; and a removable shoe to support said coaxial cable radially opposite to said aperture.
