Abstract

An electrical connector for use on an electrical cable, for drawing power from the cable, includes a body having upper and lower sides, the lower side including a channel which opens to the exterior on the lower side such that the cable can be laterally inserted into the channel from the lower side, a clamp in the channel for clamping the cable in the channel, and an operator on the upper side for operating the clamp, the operator being operable through a screw action. Also included is a pair of conductors, each conductor having a sharp lower end for piercing the cable clamped in the channel to make contact with a respective conductive core of the cable, and an upper end for external electrical connection on the upper side.

Claims

1. An electrical connector for drawing power from an electrical cable, the electrical connector comprising:

a body having a first side including a channel which opens on the first side so that an electrical cable can be laterally inserted into the channel from the first side;

a clamp in the channel for clamping the electrical cable in the channel, wherein the clamp comprises left and right clamp members;

an operator for operating the clamp through a screw action, the operator being located on a second side of the body, distinct from the first side, and

moving the left and right clamp members to reduce effective width and depth of the channel relative to the electrical cable so that the electrical cable is centered and clamped substantially simultaneously; and

a pair of conductors, each conductor having a sharp first end for piercing insulation of the electrical cable when clamped in the channel to make contact with a respective conductive core of the electrical cable, and a second end for external electrical connection, wherein the left and right clamp members are located symmetrically with respect to the conductors so that the electrical cable is centered and clamped with the conductive cores substantially in alignment with the first ends of the corresponding conductors.

2. The electrical cable connector as claimed in claim 1, wherein the second side of the body is opposite the first side.

3. The electrical cable connector as claimed in claim 1, wherein the second ends of the conductors are located, for external electrical connection, on the second side of the body.

4. The electrical cable connector as claimed in claim 1, wherein each of the left and right clamp members is slidably supported by the body for linear movement by the operator, towards a base of the channel, at an acute angle, so that the electrical cable is clamped against the base.

5. The electrical cable connector as claimed in claim 1, wherein the channel has a protruding central rib to assist centering of the electrical cable being clamped.

6. The electrical cable connector as claimed in claim 1, wherein the left and right clamp members have identical construction and are positioned symmetrically with respect to the conductors.

7. The electrical cable connector as claimed in claim 1, wherein the operator comprises a central core in engagement with the clamp through the body and a knob on the second side in engagement with the core for rotation to move the central core and operate the clamp.

8. The electrical cable connector as claimed in claim 7, wherein the central core has a bifurcated end facing in a direction opposite from the channel, the end having external screw threads engaging the knob and moving upon rotation of the knob.

9. The electrical cable connector as claimed in claim 8, wherein the second side of the body includes a hub flanked by the bifurcated end of the central core, the conductors being mounted on the hub.

10. The electrical cable connector as claimed in claim 7, wherein the central core is in sliding engagement with the clamp for moving, and thus operating, the clamp in a direction along the first and second sides of the body and, simultaneously, in a direction perpendicular to the first and second sides of the body.

11. The electrical cable connector as claimed in claim 1, wherein the channel has a base against which the electrical cable is to be clamped and within which the first ends of the conductors are initially positioned, the base being movable by the operator upon continual operation, after the electrical cable has been clamped, towards the first ends, thereby pressing the electrical cable against the first ends, for piercing of the insulation.

12. The electrical cable connector as claimed in claim 11, wherein the body has separate first and second parts on the first and second sides, respectively, the first part including the channel and the second part including the conductors, and including a spring acting between the first and second body parts and that is compressed, upon continual operation of the operator, in movement of the base towards the first ends.

13. The electrical cable connector as claimed in claim 1, wherein the second end of each conductor comprises an inwardly inclined grip section co-operable with an adjacent section for gripping and thus connecting an end of an electrical cable conductor.

14. An electrical connector for connecting conducting cores of a first electrical cable to respective conducting cores of a second electrical cable without severing of the first electrical cable, the connector comprising:

a body having a first side that includes a channel for receiving and clamping of a first electrical cable;

a clamp operatively arranged within the channel and slidably engaged with the body, having a first position opening the channel, while the clamp is engaged with the body, for lateral insertion of the first electrical cable in the channel, and a second position closing the channel, while the clamp is engaged with the body, and clamping the first electrical cable against the body;

an operator for sliding the clamp, while engaged with the body, between the first and second positions, the operator being located on an opposite side of the body from the channel; and

a pair of conductors, each conductor having a sharp first end for piercing insulation of the first electrical cable when clamped within the channel and making contact with a conducting core of the first electrical cable, and a second end for electrical connection to a conducting core of a second electrical cable.

15. The electrical cable connector as claimed in claim 14, wherein the second ends of the conductors are located, for external electrical connection, on the second side of the body.

16. The electrical cable connector as claimed in claim 14, wherein the clamp comprises left and right clamp members movable by the operator from the first position toward the second position, reducing width and depth of the channel relative to the first electrical cable.

17. The electrical cable connector as claimed in claim 16, wherein the left and right clamp members have identical construction.

18. The electrical cable connector as claimed in claim 14, wherein the operator comprises a central core in engagement with the clamp through the body and a knob on the second side in engagement with the core for rotation to move the central core and operate the clamp.

19. The electrical cable connector as claimed in claim 18, wherein the central core has a bifurcated end facing in a direction opposite from the channel, the end having external screw threads engaging the knob and moving upon rotation of the knob.

20. The electrical cable connector as claimed in claim 18, wherein the central core is in sliding engagement with the clamp for moving, and thus operating, the clamp in a direction along the first and second sides of the body and, simultaneously, in a direction perpendicular to the first and second sides of the body.
