Abstract
Abstract The invention relates to an electrical junction box having a base, a frame and a cover as the three basic parts thereof. A Ushaped wire stirrup engages and cooperates with camming surfaces on the frame and cover in a manner so as to permit the easy and convenient locking together of the three basic members of the junction box.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
An electrical junction box comprising a base, a frame, bracket means attached to said base having a pair of spaced and downwardly facing locking surfaces, said frame having stirrup holes adjacent said locking surfaces, said frame having stirrup holes adjacent said locking surfaces, a generally U-shaped stirrup having a pair of legs, laterally extending hooks attached to said legs and disposed in said holes, first camming means on said frame for biasing said legs to move said hooks into locking engagement with said locking surfaces, and second camming means on said frame for biasing said legs to move said hooks out of locking engagement with said locking surfaces, a cover, pivotal connecting means between said cover and said frame, engageable clamping surfaces on and between said cover and said frame, and an abutment surface on said cover engageable with said stirrup to move said stirrup into a locking position.
