Patent number: 9224519Abstract: A cover assembly for covering an elongate substrate includes a resilient, elastically expandable sleeve member and a holdout device. The sleeve member defines an axially extending inner sleeve passage. The holdout device includes a generally tubular core mounted in the inner sleeve passage. The core defines axially opposed end openings and a core passage extending therebetween to receive the elongate substrate. The core retains the sleeve member in a radially expanded state and can be withdrawn from the sleeve member to release the sleeve member to radially contract onto the elongate substrate. The holdout device is configured such that, after removal of the sleeve member from the core, the core can be laterally removed from the elongate substrate.Type: GrantFiled: December 13, 2012Date of Patent: December 29, 2015Assignee: Tyco Electronics CorporationInventors: Timothy J. McLaughlin, Matthew Spalding

Patent number: 6248956Abstract: An annular guard (20) for mounting on a high voltage insulator extends laterally thereof for a sufficient distance so as to prevent small wildlife such as squirrels from forming a short circuit between the opposing ends of the insulator at high voltage and earth potential respectively. The guard (20) is formed in two planar parts (24, 26) that are pivoted together (28) so that they can be relatively rotated between an open condition for mounting onto a live insulator and a closed condition for being secured thereto. Overlapping regions of the two parts are secured together (30, 32, 34, 36, 38) in the closed condition.Type: GrantFiled: June 16, 1999Date of Patent: June 19, 2001Assignees: Tyco Electronics U.K. Limited, Georgia Power CompanyInventors: Michael Robert Cook, Donald Christopher Cowley Barrett, Matthew Spalding, Michael Harben
