Abstract
A test connector for checking electrical circuits of a vehicle or the like, such as the circuits between a truck and a towed trailer or between two sections of a semitrailer highway vehicle, including an elongated dielectric body enclosing a plurality of indicator lamps visible through lenses on an indicator panel having indicia thereon identifying the particular circuits. Male or female contacts from the vehicle may be plugged into a mating electrical connector for coupling each of the lamps into a corresponding electrical circuit to be tested. An electrically conductive hook extends from the body to provide a means for supporting the connector to the vehicle and an electrical ground connection between the test connector and the vehicle.
Claims6
A test connector for testing electrical circuits of highway tractor and trailer vehicles, comprising:
- a. an elongated body;
- b. a transverse bulkhead extending across said body and being electrically non-conductive;
- c. a plurality of contacts mounted in said transverse bulkhead for making electrical connection with the electrical circuits;
- d. a plurality of electrical lamps, each provided with a first and second terminal and being supported by said body such that illumination of each lamp provides visual indications of voltage being applied to an associated electrical circuit;
- e. means for electrically connecting each of said first terminals of said electric lamps with each of said corresponding contacts;
- f. an electrically conductive hook;
- g. means for electrically connecting said hook to each of said second terminals of said electric lamps;
- and
- h. an indicator panel transmitting the illumination of each lamp to the exterior of said elongated body and positioned in overlying relation to said lamps, said hook connected with said body, having a portion thereof extending from said body for supporting said test connector, and making an electrical ground connection between each of said electric lamps and one of said vehicles such that a plurality of complete test connector circuits connecting such electrical circuits of a vehicle to the ground can be provided through said contacts, said means electrically connecting said lamps with said corresponding contacts, said electric lamps, said means electrically connecting said hook and said electric lamps, and said hook.
