Abstract
A miniature overvoltage protection device including a back-up air gap for use in miniature telephone modules and related equipment includes a generally U-shaped bracket adapted to receive an overvoltage protection device thereon and has a bracket insulating member with a dielectric disposed between the overvoltage protection device terminals and the ground provided on a U-shaped bracket in order to provide back-up air gap protection. In addition, it may include a thermally sensitive material to insulate the overvoltage protection device from the grounding bracket which is activated upon excessive heat occurring in the overvoltage protection device.
Claims11
A miniature overvoltage protection apparatus with a back-up air gap assembly comprises, in combination:
- A. a generally U-shaped bracket having;
- a) a central portion,
- b) a pair of arms, said pair of arms exerting an inwardly directed pressure, each one of said pair of arms being adapted to be insulated from electrically conductive contact with the first and second terminals of an overvoltage protection device, and
- c) bracket means having a flat portion and at least one finger portion folded upon itself to retain said back-up air gap assembly, said back-up air gap assembly including,
- i) dielectric means having a first and a second surface and at least one through aperture, said dielectric means first surface being in contact with said flat portion of said bracket means, said dielectric means second surface being in contact with said arm of said U-shaped bracket, and
- ii) insulation means disposed between said second surface of said dielectric means and said folded finger portion of said bracket means.
