Weatherproof positive lock connector
First Claim
1. An improved, weatherproof, snap-on, positive lock connector device for electrical conduits, said device comprising, in combination:
- a. a male plug comprising a housing havingi. a central tubular component having a cavity extending therethrough adapted to receive an electrical conduit at the rear end thereof,ii. a plurality of flexible fingers extending forwardly from the front end of said tubular component, said fingers having terminal pads,iii. a sleeve concentric with and peripheral of said fingers to define with said fingers a peripheral space therebetween, and,iv. sealing means disposed in said space and around said tubular component for thermally sealing said tubular component against atmospheric conditions;
b. a female receptacle comprising a housing havingi. a central tubular member having a cavity extending therethrough adapted to receive an electrical conduit at the rear end thereof,ii. a plurality of spaced peripheral recesses in the outer surface of said tubular member aligned with and adapted to receive said fingers,iii. a sleeve concentric with, slideable over and peripheral of said tubular member to define a peripheral space therebetween, said sleeve being receivable within said male plug sleeve,iv. locking means comprising tabs in said female receptacle peripheral space movable between a forward locked position over said recesses and a rearward unlocked position away from said recesses, said tabs being automatically urgeable into said unlocked position by said finger pads during engagement of said male plug and female receptacle,v. spring means urging said locking means into said locked position and said sleeve into a forward position, and;
vi. sealing means for thermally sealing said female receptacle against atmospheric conditions.

Abstract
The device comprises a male plug and a female receptacle, each of which has a housing with an electrically insulative central tubular component and a cavity extending through and adapted to receive an electrical conduit. When the plug and receptacle are joined together, electrical conduit ends disposed in the plug and receptacle are electrically interconnected. Both the plug and receptacle also include components for securing the conduits in place and components for thermally sealing the conduits therein against atmospheric conditions. The male plug has flexible fingers extending from its front end while the receptacle has its tubular member dimensioned such that it spreads the fingers as the plug and receptacle are joined together. The receptacle tubular member has recesses into which the finger ends snap to hold the plug and receptacle together. Tabs slide over these recesses to releasably lock the fingers in the recesses. The fingers are retractable from the recesses, thus permitting uncoupling of the plug and receptacle, by sliding the outer sleeve of the receptacle rearwardly against an internal spring and carrying with it the locking tabs to a rear unlocked position. The device is simple, durable and highly effective. It is utilized in interconnecting nuclear reactor cable components and in other high temperature corrosive environments. The device is also useful in high frequency electrical conductor applications.
