Metal clip for electrically connecting a conductive wire to a metal element
This disclosure concerns a metal clip for electrically connecting a conductive wire to a planar metal element, the metal clip having an S-shaped cross-section and being composed of three wings, a first wing and a second wing defining a first longitudinal recess allowing the metal clip to be attached to an edge of the planar metal element, the second wing and the third wing defining a second longitudinal recess. The second recess is provided with connection means for receiving the end of the conductive wire and for maintaining electrical contact between the conductive wire and the metal clip.
1. A metal clip for electrically connecting a conductive wire to a planar metal element, with the metal clip having an S-shaped cross-section and being composed of three wings, with a first wing and a second wing defining a first longitudinal recess allowing the metal clip to be attached to one edge of the planar metal element, with the second wing and the third wing defining a second longitudinal recess, the second recess including connection means for receiving the end of the conductive wire and for maintaining electrical contact between the conductive wire and the metal clip, wherein the connection means comprises an additional part for attaching the conductive wire in the second recess that includes a part protruding through an opening formed on the third wing, with the protruding part being provided with a side opening for receiving the end of the conductive wire, with the protruding part being movable so as to allow the clamping of the conductive wire between the perimeter of the opening of the protruding part and a surface of the third wing.
2. The metal clip of claim 1 , wherein the first wing and/or the second wing includes at least one cut forming an elastic lug oriented toward the inside of the first recess so as to improve the attachment of the metal clip to the planar metal element and the electrical contact.
3. The metal clip of claim 1 , wherein at least a portion of the perimeter of the side opening of the protruding part includes a blade for cutting an insulating sheath of the conductive wire and the electrical contact between the conductive wire and the metal clip.
4. The metal clip of claim 3 , wherein the protruding part is configured so as to be moved in a sink direction perpendicular to the plane defined by the third wing.
5. The metal clip of claim 3 , wherein the protruding part is configured so as to be rotationally moved.
6. The metal clip of claim 1 , wherein the protruding part is configured so as to be moved in a sink direction perpendicular to the plane defined by the third wing.
7. The metal clip of claim 1 , wherein the protruding part is configured so as to be rotationally moved.
8. The metal clip of claim 1 , wherein the first wing and/or the second wing includes at least one cut forming an elastic lug oriented toward the inside of the first recess so as to improve the attachment of the metal clip to the planar metal element and the electrical contact.
9. A metal clip for electrically connecting a conductive wire to a planar metal element, with the metal clip having an S-shaped cross-section and being composed of three wings, with a first wing and a second wing defining a first longitudinal recess allowing the metal clip to be attached to one edge of the planar metal element, with the second wing and the third wing defining a second longitudinal recess, the second recess including connection means for receiving the end of the conductive wire and for maintaining electrical contact between the conductive wire and the metal clip, wherein the connection means include:
a clamping lug formed by a cutout in the third wing and oriented toward the inside of the second recess; and
a guided opening formed in the third wing for introducing the end of the conductive wire into the second recess and for blocking the conductive wire between the clamping lug and the second wing.
10. The metal claim of claim 9 , wherein the metal clip consists of a single metal part.
11. The metal clip of claim 10 , wherein the clamping lug and the guided opening are arranged on the third wing so as to allow the introduction of the end of the conductive wire toward the bottom of the second recess.
12. The metal clip of claim 11 , wherein the bottom of the second recess is provided with a clearance opening for the conductive wire to jut out above the metal clip.
13. The metal clip of claim 9 , wherein the first wing and/or the second wing includes at least one cut forming an elastic lug oriented toward the inside of the first recess so as to improve the attachment of the metal clip to the planar metal element and the electrical contact.
