J. J. Cooper -11 WIDE-RANGE INSULATING/SEALING SLEEVE Abstract of the Disclosure: An insulating and sealing sleeve for use with bus bar connectors of underground power distribution systems. The sleeve includes a generally cylindrical elastomeric body having internal sealing rings at one end thereof for sealing- ly engaging the bus bar and a reentrant and generally flex- ible constricted portion at the other end thereof. The axially inner end of the reentrant portion includes a tubular portion which extends axially outwardly and joining a tapered portion which flares outwardly and which terminates at the other end of the sleeve. The internal surface of the reen- trant portion includes a plurality of grooves along the tubu- lar and flared contours and which sealingly engage the insu- lation portion of a conductor which is mechanically fastened and electrically connected to the bus bar. The internally tapered grooved portion accommodates a relatively wide range of conductor sizes and the tubular portion ensures that a plurality of grooves will sealingly engage the minimum con- ductor size. The tapered portion also permits the insulated portion of the conductor to partially enter the sleeve before the stretching operation of the installation begins. - 1 -
