Abstract
A wire clamping device including a body, at least one bore through the body for an end of a wire and at least one channel in the body converging at an acute angle and into communication with the bore towards an inlet end of the bore. An abutment is at an end of the channel remote from the inlet end of the bore, and a wedge is movable along the channel between the abutment and a region of communication with the bore. A face of the wedge facing the abutment is provided with an undercut groove, and a hole is provided through the abutment for passage therethrough of a rod-like tool provided with diametrically opposed projections at one end for pulling engagement with the undercut groove by partial rotation of the tool from an insertion position.
Claims32
A wire clamping device comprising a body (21);
- at least one bore (22) through the body for an end of a wire (23);
- at least one channel (24) in the body converging at an acute angle and into communication with the bore towards an inlet end (25) of the bore;
- an abutment (26) at an end of the channel remote from the inlet end of the bore;
- and a wedge (27) movable along the channel between the abutment and a region of communication with the bore, wherein a face (28) of the wedge (27) facing the abutment (26) is provided with an undercut groove (29), and a hole (30) is provided through the abutment for passage therethrough of a rod-like tool (31) provided with diametrically opposed projections (32) at one end for pulling engagement with the undercut groove (29) by partial rotation of the tool from an insertion position.

- at least one channel (24) in the body converging at an acute angle and into communication with the bore towards an inlet end (25) of the bore;
- an abutment (26) at an end of the channel remote from the inlet end of the bore;
- and a wedge (27) movable along the channel between the abutment and a region of communication with the bore, wherein a face (28) of the wedge (27) facing the abutment is provided with an undercut groove (29), and a screwthreaded hole (30) is provided through the abutment (26) for rotation therein of a screw (39) provided with a necked tip (40) at one end rotatably engaged with the undercut groove (29) in the wedge (27), to enable the wedge to be pushed and pulled by rotation of the screw (39) in one direction or another direction, another end of the screw being provided with means (41) for effecting rotation of the screw.

- at least one bore (22) through the body for an end of a wire (23);
- at least one channel (24) in the body converging at an acute angle and into communication with the bore towards an inlet end (25) of the bore;
- an abutment (26) at an end of the channel remote form the inlet end of the bore;
- and a wedge (27) movable along the channel between the abutment and a region of communication with the bore, wherein a face (28) of the wedge (27) facing the abutment is provided with an undercut groove (29), and the abutment (26) is provided with a plain hole (30), and a screw (39) is provided with a nut (47) non-rotatably slidable along the channel (24), with a coil compression spring (48) between the nut and the abutment;
- the nut (47) being initially positioned adjacent a necked tip (40) of the screw (39) so that an inserted wire end (44) can push the wedge (27) towards the abutment (26) against the urge of the spring (48), the screw (39) can then be rotated in a first direction to draw the nut (47) towards the abutment (26) so as to compress the spring (48) completely, whereafter further rotation of the screw (39) in the first direction urges the wedge (27) into locking engagement with the wire (23).
A wire clamping device comprising a pair of bores (22A, 22B) disposed in close side-by-side relationship, with respective inlet ends (25A, 25B), at opposite ends of the body (21) and with respective channels (24A, 24B), abutments (26A, 26B) and wedges (27A, 27B), with the channels (24A, 24B) converging in opposite directions with the respective bores (22A, 22B) to regions of communication between the respective channels and bores closely adjacent each other, and with a wall portion (49) therebetween capable of localized distortion under forces exerted by the wedges (27A, 27B) through inserted wires (23) to increase frictional contact of the wires with the respective bores (22A, 22B), wherein at least one of said wedges (27A) has its face (28) facing the respective abutment (26A) provided with an undercut groove (29), the respective abutment (26A) is provided with a hole (30), and a screw (39) which is rotatable in the hole in the abutment, wherein the screw is provided at one end with a necked tip (40) rotatably engaged with the undercut groove (29) in said at least one of said wedges (27A) to enable said at least one of said wedges to be pushed and pulled by rotation of the screw (39) in one direction or another direction another end of the screw (39) being provided with means (41) for effecting said rotation of the screw.
