Abstract

A grounding connector including a base plate having a plurality of grooves for aluminum clad or other similar metal clad telephone cables and a pressure pad adapted to be removably coupled with the base plate to facilitate retention of the metal clad telephone cables in the grooves. The connector is adapted to be connected to ground. Each groove has a configuration for assisting and retaining the metal clad telephone cables therein and grounding the cable.

Claims

1. A grounding connector comprising:

a base plate having a plurality of grooves for metal clad telephone cables, a pressure pad adapted to be removably coupled with the base plate to facilitate retention of the metal clad telephone cables in the grooves, means on the connector for connecting to ground, and each groove having a configuration including an inwardly extending interferring surface on the surfaces forming each groove in position to engage and assist in retaining the metal clad telephone cables therein and grounding the cables.

2. The invention in accordance with claim 1 wherein the connector is formed of electrically conductive material.

3. The invention in accordance with claim 1 wherein each groove in the base is an arcuate recess having a parabolic-V groove configuration.

8. The invention in accordance with claim 1 wherein the connector is grounded by means of at least one threaded aperture and set screw arrangement adapted to receive and hold a ground wire to ground the connector and cables mounted therein.

9. The invention in accordance with claim 1 wherein means is provided for mounting at least two connectors on top of one another and securing adjacent connectors to one another to form a plurality of the grounding connectors for metal clad telephone cables.

10. The invention in accordance with claim 1 wherein there are two pressure pads and four grooves on the base plate in side by side relationship, with each pressure pad adapted to be coupled with a pair of adjacent grooves.

11. The invention in accordance with claim 1 wherein the pressure pad is adapted to be removably coupled with the base plate and to cooperate with the base plate in forming the means for connection to ground.

12. The invention in accordance with claim 1 wherein the connector is formed of an extruded aluminum alloy material and is adapted for grounding aluminum sheath telephone cables with the use of a solid copper ground wire.

4. A grounding connector comprising;

a base plate having a plurality of grooves for metal clad telephone cables, a pressure pad adapted to be removably coupled with the base plate to facilitate retention of the metal clad telephone cables in the grooves, means on the connector for connecting to ground, and each groove having a configuraton for assisting in retaining the metal clad telephone cables therein and grounding the cables, and each groove is an arcuate recess formed in the base plate with a plurality of teeth extending inward from the peripheral edge portion of the groove to form a saw tooth configuration.

5. A grounding connector comprising:

a base plate having a plurality of grooves for metal clad telephone cables, a pressure pad adapted to be removably coupled with the base plate to facilitate retention of the metal clad telephone cables in the grooves, means on the connector for connecting to ground, and each groove having a configuration for assisting in retaining the metal clad telephone cables therein and grounding the cables, each groove is formed of an arcuate configuration with a plurality of teeth extending inward from the peripheral edge portion thereof, the configuration of the recess and the teeth cooperating to assist in retaining at least one metal clad telephone cable in the groove and ground the cable.

6. The invention in accordance with claim 5 wherein there are four grooves in side by side position on the base plate and a projection on the pressure pad adapted to cooperate with each groove in retaining a cable in the connector when the pressure pad is coupled with the base plate.

7. The invention in accordance with claim 6 wherein the pressure pad is coupled to the base plate by use of an arrangement of threaded fasteners passed through cooperating threaded holes in the pressure pad and the base plate.
