Electrical cable retention
The present application discloses an assembly ( 30, 40 ) for securing an electrical cable ( 1 ) to a body ( 3 ) such as the body of an electrical appliance. The assembly comprises a clamping member ( 30 ) comprising a pair of spatially separated cable holes ( 31 ) dimensioned to receive the electrical cable and a pair of guide channels ( 33 ) inwardly extending from opposing edges ( 34 ) of the clamping member and a pair of anchoring members ( 40 ) for securing the clamping member to the body, each anchoring member comprising a major surface ( 41 ) transversely extending from a mounting surface, the major surface having an edge region defining a guide rail ( 42 ) for engaging with one of the guide channels and a pair of spatially separated ribs ( 43, 44 ) extending from the edge region across said major surface for retaining the clamping member. At least the anchoring members may form an integral part of the body of the electrical appliance. Also disclosed are an electrical appliance including at least part of this assembly and the method of securing an electrical cable to a body using this assembly.
1. An assembly for securing an electrical cable to a body, the assembly comprising:
a clamping member comprising a pair of spatially separated cable holes dimensioned to receive the electrical cable and a pair of guide channels inwardly extending from opposing edges of the clamping member; and
a pair of anchoring members for securing the clamping member to the body, each anchoring member comprising a major surface transversely extending from a mounting surface, the major surface having an edge region defining a guide rail for engaging with one of the guide channels and a pair of spatially separated ribs extending from the edge region across said major surface for retaining the clamping member.
2. The assembly of claim 1 , wherein the pair of spatially separated ribs includes a first rib and a second rib, wherein:
the first rib is shaped to allow irreversible passage of the clamping member along the guide rail towards the second rib; and
the second rib is shaped to prevent passage of the clamping member along the guide rail beyond the second rib.
3. The assembly of claim 2 , wherein the first rib has a triangular cross-section including a surface section normal to the major surface, the surface section facing the second rib.
4. The assembly of claim 2 , wherein the second rib has a rectangular cross-section.
5. The assembly of claim 1 , wherein each anchoring member further comprises a further rib on the major surface, the further rib extending from the second rib to the mounting surface.
6. The assembly of claim 5 , wherein the further rib is outwardly tapering in the direction of the mounting surface.
7. The assembly of claim 1 , wherein the pair of anchoring members are adjoined by a mounting plate comprising their respective mounting surfaces.
8. The assembly of claim 1 , wherein the spatially separated cable holes are separated by a body portion of the clamping member, said guide channels extending into said body portion.
9. The assembly of claim 1 , wherein the clamping member is plate-shaped.
10. The assembly of claim 1 , wherein the clamping member is made of plastic, a metal or a metal alloy.
11. The assembly of claim 1 , wherein each anchoring member is made of plastic, a metal or a metal alloy.
12. An electrical appliance comprising a body, the body comprising at least the anchoring members of the assembly of claim 1 secured to the body.
13. The electrical appliance of claim 12 , wherein the anchoring members are integral to the body.
14. The electrical appliance of claim 12 , wherein the electrical appliance is a luminaire.
15. A method of securing an electrical cable to a body using the assembly of claim 1 , the method comprising:
securing the anchoring members to the body;
securing the electrical cable in the cable holes of the clamping member; and
sliding the guide channels of the clamping member including the secured electrical cable along the guide rails of the anchoring members to secure the clamping member between respective pairs of spatially separated ribs.
