Abstract: A transmission wire connector includes a first wire contact member and a second wire contact member mounted in bores in a base unit wherein the first and second contact members may slide to make contact with an exchange linked wire, and a consumer linked wire respectively, the first and second wire contacts within the base unit being isolated from one another; together with a separable module unit cable of coupling with the base unit and providing direct or indirect electrical connection between the first and second contacts when the module unit is coupled to the base unit, the separable module unit being one of a plurality of such module units arranged to provide different functions to the connector or a wire it connects.

Abstract: The application describes an electrical terminal comprising a pair of longitudinally disposed contact members, each having a pair of insulation displacement connectors connectors, one at either end thereof, thereby to link two wire pairs, wherein. each contact member comprises a contact arm each extending in a defined direction, the contact arms leading to a pair of arrestor contacts spaced so as to accept a surge arrestor. The defined direction is preferably substantially transverse to the contact members. This enables the surge arrestor to be placed to one side of the electrical terminal, avoiding interference with ingoing and outgoing wires and avoiding inhibiting access to test points. The contact members are preferably parallel within the electrical terminal. The arrestor contacts are preferably spring contacts, thereby to enable replacement of the arrestor. The contact arms more preferably end at the spring contacts.

Abstract: A connector unit is described comprising a base unit 12 and a connector module 10, the base unit 12 comprising a walls 14 for accepting the connector module 10, the connector module 10 including at least one IDC connector 36 for making electrical connection with a wire 48 and channels 26 for retention of a wire 48, wherein the connector module 10 is such that insertion thereof into the base unit 12 causes the IDC 36 connector to move relative to the channels 26 thereby to make electrical connection between the IDC connector 36 and a wire 48 in the channels 26.

Abstract: A material for wrapping around a pipe, cable or the like in which a flexible sheet of heat shrinkable material such as cross-linked polyolefin, is provided on each edge with a metal clip element. In one construction, the two elements being formed with a body portion attached to the sheet material and hook members which extend in the opposite sense to one another and are inclined towards the body member to hook into one another. A strip of material on one of the clip elements, or on the flexible material, extends under the free edge of one of the hook members to maintain the other hook member in engagement. In another construction the first clip element is provided with spaced apart bridge which are engaged with cooperating spaced apart hooks on the second clip element.
