Insulated cable attachment device
View Patent ↗An insulated cable attachment device, made of an electrically insulating material, is connectable to a termination connector which is in turn connectable to a tap port for a cable television system. When an installer disconnects service to a subscriber's house, the signal is shut down to the tap port to which the subscriber drop cable is connected. The drop cable is disconnected from the tap port and a terminator connector is connected in its place on the tap port. The installer then installs the insulated cable attachment device onto the terminator connector before connecting the drop cable to the insulated cable attachment device, thereby preventing any difference in ground potentials between the terminal connector and the drop cable from being transmitted to the end of the drop cable near the house.
1. A device connectable to a termination connector which is in turn connectable to a tap port for a cable television system, comprising:
a unitary one-piece body of an electrically insulating material;
the unitary one-piece body having first and second portions connected to each other by a shoulder;
the first portion defining a first cavity and a second cavity, wherein a part of the first portion adjacent the second cavity includes a plurality of internal threads which are connectable to a corresponding plurality of external threads on the termination connector;
the second portion including a plurality of external threads thereon which are connectable to a corresponding plurality of internal threads on a cable connector; and
the second portion defining a third cavity, wherein the third cavity accommodates a central conductor of a coaxial cable to which the cable connector is attached.
2. A device according to claim 1 , wherein the first portion covers a shank of the termination connector when the device is screwed onto the termination connector.
3. A device according to claim 1 , wherein the unitary one-piece body is made of polyacetal resin.
4. A method for manufacturing a device connectable to a termination connector which is in turn connectable to a tap port for a cable television system, comprising the step of making a unitary one-piece body of an electrically insulating material, wherein:
the unitary one-piece body has first and second portions connected to each other by a shoulder;
the first portion defines a first cavity and a second cavity, wherein a part of the first portion adjacent the second cavity includes a plurality of internal threads which are connectable to a corresponding plurality of external threads on the termination connector;
the second portion includes a plurality of external threads thereon which are connectable to a corresponding plurality of internal threads on a cable connector; and
the second portion defines a third cavity, wherein the third cavity accommodates a central conductor of a coaxial cable to which the cable connector is attached.
5. A method according to claim 4 , wherein the first portion covers a shank of the termination connector when the device is screwed onto the termination connector.
6. A method according to claim 4 , wherein the unitary one-piece body is made of polyacetal resin.
7. An insulation device for use with a terminal connector and a coaxial cable connector, the terminal connector having a plurality of terminal external threads at one end and the coaxial cable connector having a plurality of cable connector internal threads, comprising:
a unitary one-niece body of electrically insulating material having a first body portion and a second body portion;
wherein a part of the first body portion includes a plurality of first body internal threads which are connectable to the plurality of terminal external threads;
wherein a part of the second body portion includes a plurality of second body external threads connectable to the plurality of cable connector internal threads; and
wherein the second body portion is adapted to accommodate a central conductor of a coaxial cable to which the cable connector is attached.
8. A device according to claim 7 , wherein the unitary one-piece body is made of polyacetal resin.
