Abstract
Abstract The shock prod comprises a circuit for producing high-voltage electrical pulses. The circuit is mounted in a housing and communicates electrically with two conductors integral with a prod extension. The prod extension extends from the housing in a fixed predetermined direction with respect to the housing. The extension is elongated in the fixed direction, terminates in a free end, and is generally flat with a high width-to-thickness ratio, having sufficiently high flexural rigidity and buckling resistance to avoid excessive deflection or deformation in use. With this novel configuration, the extension is constrained to bend in a preferred plane parallel to the thickness dimension. Loads applied in the other planes produce torsional deflection so as to allow bending in this preferred deflection plane. This wide, thin cross-section permits a wide electrode spacing simultaneously with a thin bending surface, resulting in the following: A minimum bending radius which greatly reduces instances of breakage; allows electrification and desired electrode spacing over any desired portion of the prod extension; eliminates need for separate electrode mounting hardware; remains operational even if the extension is snapped in two, when a sufficient electrode-conductor spacing geometry exists along the length of the prod extension.
