US 5,629,826 A · Retractable cord surge protector

Abstract

An inexpensive, compact, portable, retractable cord, visual indicator, electrical/telephone connector-type surge protector, which comprises a housing composed of a molded plastic, with two female receiving grounding inlets on its upper surface, a visual indicator light, and a pair of female telephone inlets on one side. On another side, the housing has two openings for a retractable electrical extension cord and a retractable telephone cord. On the opposite side of the housing are two independent, retaining, on-off switches for the two cords. The housing is composed of two sections, an upper and lower section, with an inner spring coil mechanism on two independent reels in each section for the electrical and telephone cords respectively. The invention is designed to be used with standard electrical apparatus or other sensitive electrical devices, which are to be protected from electrical surges, where extension cords may be required, and allows for the retraction of the cords when not required.
