Abstract

A coaxial cable testing device has a modular construction wherein the several pieces may be configured in different arrangements to fulfill the separate functions of a flashlight, a continuity checker, a cable identifier, and a bandit splitter detector. The pieces are provided with connector elements which allow each of the pieces to fit together and the pieces are small enough to conveniently fit in the shirt pocket of a cable television technician. In the flashlight configuration, a battery pack (10) and a flexible flashlight assembly (18) are interconnected. In the continuity checker or cable identifier configuration, the battery pack (10) is connected to one end of a cable (28) and the detector section (24) and shorting plug (26) are connected to the other end of the cable (28). In the bandit splitter detector configuration, the battery pack (10) is connected to the detector section (24) which is connected to the cable (28). An LED (32) provides visual signals to the technician when continuity is determined or bandit splitters are detected.

Claims

1. A modular cable testing device, comprising:

a battery pack, said battery pack including a first connecting means;

a detector section for determining cable continuity, identifying one cable from a plurality of cables, or detecting electrical shorts in a cable, said detector section including a visual signalling means for signalling a cable is continuous, a particular cable is identified, or an electrical short is present in a cable, said detector section including a second connecting means and a third connecting means;

a shorting plug providing a return path for electrical current, said shorting plug including a fourth connecting means;

said first connecting means being connectable to a first end of a cable or to said second connecting means of said detector section;

said second connecting means being connectable to a second end of a cable or to said first connecting means of said battery pack; and

said third connecting means being connectable to an end of a cable or to said fourth connecting means of said shorting plug.

2. A modular cable testing device as recited in claim 1 wherein said battery pack has a first fastening clip, said first fastening clip being used to secure said battery pack to a shirt pocket, said detector section has a second fastening clip, said second fastening clip being used to secure said detector section to said shirt pocket.

3. A modular cable testing device as recited in claim 1 further comprising a flexible flashlight attachment having a fifth connecting means, said fifth connecting means being connectable to said first connecting means of said battery pack.

4. A modular cable testing device as recited in claim 1 wherein said visual signal means comprises a light emitting diode.
