Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
A weatherproof electrical connector comprising: a terminal housing containing a plurality of electrical contacts; means for connecting wire leads of a sheathed conductor with said contacts; a cap for securely fitting over the rear end of said terminal housing that receives the sheathed conductor, said cap having a central aperture permitting the sheathed conductor to extend therethrough; a cylindrical rubber bushing located within said cap and encircling the position of the sheathed conductor; said cap having a plurality of recesses that run alongside said bushing and are open to the exterior surface of said bushing, said recesses each having a tapered end surface tapering toward said central aperture; said terminal housing also including a plurality of projecting flexible fingers extending toward the rear thereof that are received respectively within said recesses and engage said tapered end surfaces to be forced into firm engagement with said bushing and said bushing in turn with a conductor extending therethrough; and means for securing said terminal housing and said cap together.
