Patent

CA 2398576

A fire-rated wire etc. connector (10) is of the type having within a metal body (11) twin bores (12) at least one of which is associated with wedge means (14) preventing withdrawal of a wire (20) or suspension strand in the opposite direction to insertion, and the wedge means (14) is made of ceramic material. Wedge means (14) may be associated with both bores (12) and are preferably wedges with ribs (15) for engagement with wires (20) inserted in the bores, the wedges being guided within channels (16) which converge towards the inlet ends (17) of respective bores, with compression springs(18) between abutments (19) and the wedge means (14) to urge the latter towards an intervening thin wall (13) between the bores, and, although preferably made of stainless steel, the abutments (19) may be made of plastics because once the wedge means have become secured in gripping engagement with wires the abutments (19) and springs(18) are redundant.
