DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for an attachment for an electrical device, such as a reflector fitted with a bulb, which exhibits in the form of a pin or similar an electrical connection capable of being pushed into an electrical junction.
The principal object of the present invention is, in the first place, to make available an arrangement of the kind indicated above, which permits a reflector fitted with a bulb or some other appropriate electrical device to be attached effectively and by simple means to an electrical cable in a separable fashion.
Said object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that a coupling capable of being joined to an electrical cable, which coupling is in the form of a component attached to one end of the electrical cable in question by means of, for example, a screw or some other fastening device and provided with an electrical junction with the ability to conduct electricity, is so arranged as to function as a stop both for an electrical device and for a holder capable of being joined to the electrical device, in opposite directions.
The invention is described below as a preferred illustrative embodiment, in conjunction with which reference is made to the drawing, which shows a bulb and reflector connected together in a partially sectioned view.
At one end 1A of an electrical cable 1, which exhibits a number of conductors 1.sup.1, 1.sup.2 and which is preferably strengthened by a reinforcement 2 and is enclosed by a sheath 3, similar to a flexible conductor, for example, a fastening arrangement 4 for an electrical device 5 of an appropriate kind is capable of being connected to said electrical cable 1. In the preferred embodiment the electrical device 5 comprises a reflector 6 with an integral bulb 7, preferably a so-called halogen bulb. Said electrical device 5 exhibits a number of pins 8 or an electrical connection of similar form, which is capable of being pushed into contact with an appropriate electrical junction 9, for instance holes.
A coupling 10, which exhibits the ability to conduct electricity and is capable of being joined to an electrical cable 1 of the kind in question, for example by means of a screw 11 or some other appropriate fastening device which holds the electrical conductors 1.sup.1, 1.sup.2 securely in position on said part 10, exhibits said matching electrical junctions 9, so that the pins 8 of the bulb or other electrical connections can be joined to said electrical conductors 1.sup.1 1.sup.2 for the purpose of joining them to one another so that the bulb 7, etc., can be connected electrically so as to make contact in order, for example, to be capable of being lit at the desired moment. A casing 12, preferably in the form of a plastic hose, which is so arranged as to be shrunk by means of heat onto the electrical cable 1 and the coupling 10 so that it covers at least a part of them, may be so arranged as to protect them from contact and against being contaminated with dirt, and from damp, etc.
A holder 13 of an appropriate kind, which is capable of being joined to the electrical device 5, is so arranged as to be pushed against the coupling 10 at the same time as the electrical device 5 is pushed by the holder 13 in the direction of the coupling 10, in conjunction with which said coupling 10 is so arranged as to function as a stop both for the holder 13 and for the electrical device 5, although in opposite directions 14 and 15, so that the electrical device 5, at the same time as it is effectively restrained, is also capable of being pushed securely home so as to make good electrical contact. The holder 13 can comprise one or more sprung tensioning elements 16, 17 attached to the electrical cable 1, which are so arranged as to grip around the electrical device 5, preferably at a conveniently thickened peripheral edge 5A of same. Said tensioning elements 16, 17, which may consist of wire-like loops originating from a common and preferably divisible sleeve 18
