<p>A connector for wires or the like of the type provided with wedges (20A, 20B) slidable along respective channels (21A, 21B) in the body (22) of the connector, each channel converging at an acute angle to and into communication with a respective one of twin bores (23A, 23B) (which are separated by a thin wall (24)) towards one end (25A, 25B) of that respective bore, the wedges (20A, 20B) being provided with transverse ribs (26) on one face for gripping engagement with the wires (27A, 27B) to be connected under the urge of compression springs (28A, 28B) between the wedges and recessed abutments (29A, 29B) within the body (22) of the connector is provided with apertures (32A, 32B) in the body (22) of the connector each having an inner end opening into one channel (21A or 21B) intermediate the inlet end (25A or 25B) of the respective bore (23A or 23B), and the position of the respective wedge (20A or 20B) after insertion of a wire end (27A or 27B) into the bore and into gripping engagement with the wedge, the aperture (32A or 32B) being available as a guide for a separate tool pushed into the channel through the aperture to move the wedge against the urge of its spring to enable either wire (27A or 27B) to be withdrawn or adjusted in the opposite direction to that in which it had been inserted. The face of each wedge (20A, 20B) abutted by the respective compression spring (28A, 28B) has a concave profile consisting of two planar surfaces at an angle to each other of 150° whereby the end of the spring contacting the wedge is centralised on that face, and whereby any tendency for the wedge to rotate upon insertion or removal of a wire is resisted by an opposite moment (M' or M'') exerted by the spring against the appropriate side of the concave face of the wedge, and the concave profile terminates towards the ribbed face of the respective wedge at an integral projection of the wedge towards the respective recessed abutment (29A or 29B) to prevent migration of the respective compression spring (28A or 28B) into or through the gap between the wedge and the recessed abutment.</p> |
