Abstract

Abstract A cover or protector, combined with a cleaner, is provided for use with electrical plugs or terminals when disconnected, thus inhibiting corrosion, etc. of the conductor parts and at the same time employing an abrasive instrumentality that operates to clean the conductor parts as the plug and cover are telescopically connected and disconnected. The cover comprises a base from which projects a portion adapted to telescopically and frictionally mate with a conductor terminal. The cover is formed of non-conductor material and the projecting portion is coated with or otherwise bears an abrasive substance or particles. The cover further includes a peripheral wall for surrounding the plug to further shield it.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 219 words
For use with an electrical plug of the type having a terminal-bearing part including a free end and provided with a plurality of parallel, axially elongated terminals of cylindrical section exposed at the free end, one of which is a male terminal and the other of which is a female terminal: a protector comprising a body having first and second opposite ends including a base disposed at and closing the first end and a portion integral with the base and extending from the base to the second end and leaving the second end as a free end, the portion including a plurality of parallel terminal-receiving elements exposed at the second end of the body and being spaced apart and equal in number to the plug terminals, one of said elements being a female element and another being a male element and said elements further being cylindrically and axially configured to telescopically and frictionally interfit in moisture-proof fashion respectively with the plug terminals, the protector body further including a continuous peripheral wall integral with the base and projecting to and substantially coterminous with the second end and in spacedly surrounding relation to the male terminal-receiving element, the wall being so configured and dimensioned as to telescopically receive and surround the terminal-bearing part of the plug that provides the female terminal.
