Abstract: The present invention relates to a power line coupler for coupling a pair of cables together. The coupler includes a protector for receiving and protecting the cables. The protector includes a pair of protection members between which the cables can be received. A clamp is provided for clamping the protector and cables together.

Abstract: The present invention relates to a power line coupler for coupling a pair of cables together. The coupler comprises a protector for receiving and protecting the cables. A clamp is provided for clamping the protector and cables together. In many embodiments, the protector comprises an inner tube in which the cables can be inserted from opposite sides. In one embodiment, the clamp comprises an outer tube in which the protector is located.

Abstract: The present invention relates to a shear fastener for an electrical connector. The fastener includes a head from which a threaded shaft extends. The head defines a pair of polygonal portions separated by a recess so that an endmost one of the polygonal portions can be separated from the fastener by shearing as the fastener is tightened within the connector. Separation of opposite flats of the endmost polygonal portion is different (e.g. greater) than separation of opposite flats of the other polygonal portion. In one embodiment, the engagement socket of a pneumatic wrench can slip over the polygonal portions and rotate through 360° when rapidly tightening the fastener whilst engaging with the endmost polygonal portion, without engaging with the other polygonal portion.

Abstract: The present invention relates to a mains-power electrical connector. The connector includes a core defining passages for receiving respective cables, and apertures for receiving fasteners to fasten the cables within the passages. Windows terminate the passages. A light penetrable cover is provided for covering the core and the windows. The fasteners may be in the form of shear bolts.
