Abstract
A hardline tap includes a metallic tap housing, internal tap electronics, hardline coaxial cable sockets, and may employ, among other things, any of impedance matching, connections of reduced size, and specialty inductors to extend its application to signal distribution systems operating at more than one gigahertz.
Claims20
A cable television tap with extended frequency features comprising:
- a metallic tap housing with internal tap electronics;
- the housing having upstream and downstream sockets for receiving stingers of respective upstream and downstream coaxial cable connectors that terminate upstream and downstream hardline coaxial cables;
- a first of the sockets leading to an outer passage that is adjacent to an inner passage;
- and,
- a first of the stingers inserted through centers of the passages and thereafter through a seizing pin cage;
- wherein the first stinger passes coaxially through the inner passage with an impedance that is within 30% of the impedance of the upstream hardline coaxial cables.

A cable television tap with extended frequency features comprising:
- a metallic tap housing with internal tap electronics;
- the housing having upstream and downstream sockets for receiving stingers of respective upstream and downstream coaxial cable connectors that terminate upstream and downstream hardline coaxial cables;
- a first of the sockets having a circular outer passage interconnecting with a circular inner passage;
- a first of the stingers inserted through the centers of the passages and thereafter through a hole in a seizing pin cage;
- and,
- a seizing pin cage and a caged ball below the stinger;
- wherein the ball is urged toward a cage roof by a compression spring formed from a flattened open metallic loop, the opening in the loop or the opening ends bearing on the ball and the ball contacting the stinger.

A cable television tap with extended frequency features comprising:
- a metallic tap housing with internal tap electronics;
- the housing having upstream and downstream sockets for receiving stingers of respective upstream and downstream coaxial cable connectors that terminate upstream and downstream hardline coaxial cables;
- an inductor including wire encircling a magnetic core such that there are at least 1st, 2nd, and 3rd windings, the 2nd winding being between the 1st and 3rd windings;
- the inductor interconnecting center conductors of the upstream and downstream hardline coaxial cables;
- and,
- electrically resistive collars that do not interconnect with the windings encircling the inductor near a boundary between a 1st and 2nd winding and near a boundary between a 2nd and 3rd winding;
- wherein the collars dampen electromagnetic fields created when RF resonance occurs across the inductor.
