Electrode structure for collar mounted animal training apparatus

Claim 1

In an electronic animal control apparatus including a strap adapted to be placed entirely around a portion of an animal's body and supporting circuitry producing an electroshock signal in response to a command signal, the improvement including means designed for providing a solution to the problem of avoiding inconsistent electrode contact and loss of electrode stimulus to the animal's skin under conditions of the animal's fur being wet, comprising: first and second electrodes attached to a receiver unit and extending through holes in the strap toward the animal's body, each of the first and second electrodes including an elongated conductive probe connected to the circuitry to receive the electroshock signal, and an insulator surrounding a portion of that electrode for the purpose of preventing shunting of the electroshock signal when the animal's fur is wet, an end portion means of each of the first and second electrodes for extending only sufficiently far, specifically approximately one-eighth to one-quarter of an inch, beyond the insulator to 1) ensure consistent electrical contact of the first and second electrodes with the animal's skin without overtightening the strap, and 2) avoid substantial shunting of electrical stimulus current between the first and second electrodes through wet fur, the diameter of the end portion means of each of the first and second electrodes being approximately an eighth of an inch.
