Abstract
A terminal assembly comprises a clip 1 for a terminal of a cartridge fuse, a cradle 4, integral with the clip, and, for fitting around the cradle, a collar 6 having a clamping screw 8 in a tapped hole 7 extending therethrough. In use, the collar 6 is fitted around the cradle 4, and a bare end of an electric conductor is positioned in the cradle 4, the clamping screw 8 is being tightened to clamp the bare end against the internal surface of the cradle. <IMAGE>
Description
SPECIFICATION
An electrically conductive terminal
This invention relates to electrically conductive terminals and is especially, but not exclusively, concerned with electrically conductive terminals for use in electric plugs of the kind used in domestic and similar wiring systems.
In electric plugs used in domestic and similar wiring systems, for example the "13 amp" plugs of the kind to which British Standard Specification No.
1363 relates, it is now the general practice to provide in the plug, interconnected between the live pin and the associated terminal to which the live conductor of an electric cable is electrically connected, a cartridge fuse of a rating appropriate to the electrical appliance to which the plug is connected. The means for electrically connecting a cartridge fuse between the live pin and its associated conductor terminal are usually of such a form that a cartridge fuse can be readily changed by an unskilled user of the plug.
It is an object of the present invention to provide a simple and inexpensive electrically conductive terminal assembly which is particularly suitable for use as the conductor terminal assembly to and from which a cartridge fuse of an electric plug can be readily connected and disconnected.
According to the present invention, the improved electrically conductive terminal assembly comprises a pair of oppositely disposed resilient lugs which define a clip into which a terminal of a cartridge fuse can make a snap fit, a cradle, integral with the clip, for reception of a bare end of a cable conductor and, for fitting around the cradle, a collar having in a tapped hole extending through its wall a clamping screw for clamping a bare end of a cable conductor positioned in the cradle against the internal surface of the cradle.
The cradle may be of any suitable external crosssection provided that a clamping screw projecting between the free edges of the wall of the cradle and into the bore of the collar can clamp a bare end of a cable conductor positioned in the cradle against the internal surface of the cradle but, for ease of manufacture, preferably the cradle has an extenal shape of approximately circular form so that the collar can have a bore of circular cross-section.
Preferably, the wall of the cradle subtends an angle lying in the range 240 to 285 .
The collar may have an external cross-section of any desired shape depending on the space available in a plug housing.
Preferably, the axis of the cradle lies substantially parallel to, and may also lie along, the axis of the clip, orthe axis of the cradle may lie at any convenient angle to the axis of the clip.
The invention also includes an electric plug having an electrically conductive terminal assembly as hereinbefore described.
The invention is further illustrated by a description, by way of example, of a preferred conductor terminal assembly for use in a 13 amp electric plug, with reference to the accompanying drawing which shows an exploded perspective view of the conductor terminal assembly. Referring to the drawing, the conductor terminal assembly comprises a substantially U-shaped resilient clip 1 comprising a base 2 and a pair of oppositely disposed resilient lugs 3, a cradle 4 integral with the base of the clip and, for fitting tightly around the cradle, a collar 6 having in its wall a tapped hole 7 for reception of a clamping screw 8. As will be seen, the cradle 4 has an external shape of approximately circular form and the axis of the cradle is parallel to and lies in the same plane as the axis of the clip.In use, the collar 6 is fitted tightly around the cradle 4 so that the axis of the tapped hole 7 approximately lies midway between the free edges 5 of the wall of the collar and the assembly is mounted on the preformed base of an electric plug.
A bare end of cable conductor is positioned in the cradle 4 and the clamping screw 8 is tightened so that it passes between the free edges 5 of the wall of the cradle and clamps the conductor against the internal surface of the cradle. One terminal of a cartridge fuse can be readily connected between the lugs 3 of the clip 1.
1. An electrically conductive terminal assembly comprising a pair of oppositely disposed resilient lugs which define a clip into which a terminal of a cartridge fuse can make a snap fit, a cradle, integral with the clip, for reception of a bare end of a cable conductor and, for fitting around the cradle, a collar having in a tapped hole extending its wall a clamping screw for clamping a bare end of a cable conductor positioned in the cradle against the internal surface of the cradle.
2. An electrically conductive terminal assembly as claimed in Claim 1, wherein the cradle has an external shape of approximately circular form and the collar has a bore of circular cross-section.
3. An electrically conductive terminal assembly as claimed in Claim 1 or 2, wherein the wall of the cradle subtends an angle lying in the range 240" to 285".
4. An electrically conductive terminal assembly as claimed in any one of the preceding Claims, wherein the axis of the cradle lies substantially parallel to the axis of the clip.
5. An electrically conductive terminal assembly as claimed in Claim 4, wherein the axis of the cradle lies along the axis of the clip.
6. An electrically conductive terminal assembly substantially as hereinbefore described with reference to and as shown in the accompanying drawing.
7. An electric plug having an electrically conductive terminal assembly as claimed in any one of the preceding Claims.
