Abstract

A cable terminal for electrical connection of a wire to a component. The cable terminal ( 3 ) includes a first part ( 6 ) and a second part ( 7 ). A first part ( 6 ) connects to the wire. A second part ( 7 ) includes a longitudinal and continuous slot ( 19 ) with a first section ( 8 ), adapted to the width of a screw head on a screw with which the cable terminal is to be fitted to the component, and a second section ( 10 ), adapted to the width of the screw's threaded section. In a first position the slot ( 19 ) can be passed over the screw head in the first section ( 8 ) so that the cable terminal ( 3 ) can be displaced in a direction along the slot so that the screw ends up in a second position in the second section ( 10 ). The second part ( 7 ) of the cable terminal includes a part ( 12 ) that forms a roof ( 13 ) positioned at least partly above the first section ( 8 ).

First claim

The invention claimed is:

1. A cable terminal including a first part and a second part:
the first part is configured to receive and be in electrical contact with a wire;
the second part includes a longitudinal and continuous slot therein, the slot includes a first section with a first width across the longitudinal slot and the first section, and the first width is selected to be related to a horizontal width of a screw head on a screw with which the cable terminal is to be mounted; the slot further includes a second section with a second width across the longitudinal slot and the first section, and the second width is selected to be related to a horizontal width of a body of the screw such that
in a first position of the cable terminal relative to the screw, the slot can be slipped over the screw head in the first section of the slot, whereafter the cable terminal can be displaced in a direction along the longitudinal slot so that the screw ends up in a second position in the second section of the slot, and in the second position, the cable terminal is prevented by the screw head from being dismantled from the screw in a vertical direction of the screw;
a projecting part of the second part of the cable terminal is configured to form a roof positioned above at least part of the first section of the slot, the roof is arranged on one side of the cable terminal, the roof having a flat horizontal surface parallel to a horizontal plane of the second part, and the roof being located and configured to allow the cable terminal then in the first position to be slipped over the screw head in the first section from one direction only.

2. The cable terminal in accordance with claim 1 , wherein the projecting part roof is spaced out above the second part at a distance corresponding to at least a height of the screw head when the slot has been slipped over the screw head in the first position.

3. The cable terminal in accordance with claim 1 , wherein the projecting part has the shape of an ‘L’ including a leg up from the second part as one leg of the ‘L’ and the roof as another leg of the ‘L’.

4. The cable terminal according to claim 1 , wherein the projecting part is positioned as an extension over the first section of the slot.

5. The cable terminal according to claim 1 , wherein the projecting part has a width in a direction across the slot that is approximately as big as the first width of the first section of the slot.

6. The cable terminal according to claim 1 , wherein the roof of the projecting part is located and shaped to cover at least half of the first section of the slot longitudinally.

7. The cable terminal according to claim 1 , wherein the slot is configured to match one or more corresponding lugs on a body to which the terminal is to be mounted for orienting the terminal with reference to the body.

8. The cable terminal according to claim 1 , wherein the second width of the second section is smaller than the first width of the first section.

9. The cable terminal according to claim 1 , wherein at least some of the first and the second parts of the cable terminal and the projecting part is made in one piece.

10. A connection of an electrical wire to an electrical component including:
a cable terminal according to claim 1 ;
a device on which the second part of the cable terminal is to be mounted;
the screw is provided with the screw head above the device on which the terminal is mounted; and
a wire connected to the cable terminal.

11. The connection of claim 10 , wherein the screw has a body below the head thereof for mounting the device.

12. The cable terminal of claim 1 , wherein the second section is positioned further away from the first part than the first section in a longitudinal direction.
