Abstract
1444767 Electrical connector ITT INDUSTRIES Inc 14 Sept 1973 [2 Oct 1972] 43280/73 Heading H2E To connect releasably a cable-terminating lug to a power-off supply terminal in a heavy current circuit with minimum effort, cup-like receptacle 40 mounted on terminal 16 and likesized hole in lug 30 are coupled by sleeve 52 with axially slotted expansible ends 70, 71 opened out by the axial approach of conical nuts 82 on opposed threads of a screw 84 within the sleeve. The nuts carry projecting axial ribs engaging the axial slots 54 in the sleeve, while their conical body profiles match the conical bores, tapering towards the centre of the sleeve. The screw 84 is cross-dowelled 130 to a coupling 150 into which an eyebolt 182 may be bayonet fitted. Eyebolt 182 may be rotated or moved axially by a suitable rod-like tool. To connect terminal 16 to lug 30, sleeve 52 with nuts and screw is inserted through the hole in lug 30, into cup 40, the periphery of the mid-section of the sleeve being gripped frictionally by the surrounding housing 24. Rotation of the screw then expands and clamps the sleeve. Clearance between cup 40 and lug 30 is sufficient to withstand circuit voltage when the sleeve is removed, and optionally replaced by an insulating isolating plug. While screw rotation is not required, the conical cavity round coupling 150 may be filled by an insulating plug, optionally containing a voltage test probe of known design, screwed to thread 170 of coupling 150. In an alternative embodiment (Fig. 13, not shown) two lugs on separate cables may be connected by a similar sleeve, the end of the housing corresponding to terminal 16 being fitted with a suitable plug. The housing may comprise two housings of the first embodiment joined face-to-face by their empty supply terminal ends. The cross-section of one or both sleeve ends, and of the corresponding hole, may be non- circular, advantageous in preventing rotation and thus obviating the need for frictional grip on the mid-section of the sleeve.
