ABSTRACT:
A wire splice insulator for underground wire splices and the like is provided in the form of a pair of substantially rigid flat base members in side by side relationship, a sheet of soft conformable self-sealing cohesive elastomer beneath and adhered to said base members, a dome extending outwardly from each said base member and elastomer sheet generally centrally of the base member and forming a cavity in the base member and elastomer sheet, a plurality of semi-tubular shields in each base member and elastomer sheet extending from the dome to adjacent the edge of the base members and forming semi-cylindrical cavities in said base members and sheets, said domes and tubular sheathes in the pair of base members being mirror images of each other, a soft non-hardening mastic adhesive insulating material filling the cavities in the elastomer and a parting sheet on the elastomer sheet and mastic opposite the base members.
