Abstract
Abstract An electrical fence tester is provided having novel electrical connectors for electrically connecting the various electrical components thereof, each electrical connector comprising a pillar integrally molded into the case of the tester, an axial channel provided in the pillar, a transverse slot provided at the end of the pillar for inserting wires of the components to be connected, and a rod-form clamping member adapted to be inserted into the axial channel of the pillar and retained therein and to maintain the wires in electrical contact with each other. In one embodiment the rod-form clamping member comprises a metal rivet having a split shank, the wires to be connected being retained within the slot of the split shank, the rivet being affixed in place by melting the lip of the pillar over the rivet head, either with a soldering iron or by sonic welding. In another embodiment, the clamping members are in the form of plastic rods integrally molded on the inner surface of the cover for the tester case, the rods being inserted in the axial channels of the pillars over the wires to be connected, the cover then being sealed in place with an adhesive or by means such as sonic welding.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
An electrical fence tester comprising: A. a container, B. a cover adapted to be mounted on said container and to be affixed thereto, C. an electrical circuit comprising: 1. a plurality of resistors connected in series, the values of said resistors decreasing from one end to the other, 2. a plurality of glow lamps one connected across each of said resistors, 3. a plurality of electrical connectors connecting the respective leads of said glow lamps and said resistors to each other, each connector comprising: a. a pillar integrally molded to said container having nonthreaded axial channel and having an open transverse slot provided at the end of said pillar and communicating with said axial channel, and b. a protuberance axially slidably disposed in said axial channel in contact engagement with the walls of said axial channel engaging and maintaining the electrical leads from said glow lamps and said resistors in electrical contact, 4. external terminals connected to said circuit.
