Definitions

  • the invention relates to a connection element for a low-voltage lamp and a low-voltage lamp.
  • connection elements for example connection cables, are used to supply low-voltage lights with electricity.
  • a low-voltage lamp can e.g. be suspended with the connecting element from a busbar or held by a separate holder. In both cases, the connection element ensures the power supply of lamps of the low-voltage lamp, the connection element comprising at least a first and a second conductor.
  • the invention has for its object to facilitate the adjustability of the position of a low-voltage lamp and the alignment of a lamp.
  • a connection element for a low-voltage lamp has an inner conductor encased in insulation and an outer conductor surrounding the insulation, which together with a light source form a circuit, the inner conductor and / or the outer conductor being bendable and having such a rigidity that it maintains a shape impressed by bending. Because the inner conductor or the outer conductor can be bent into any shape, a low-voltage light or a light source carried by the connecting element can be easily aligned on all sides.
  • the connecting element can be easily bent by hand by anyone wishing to align a low-voltage lamp, the shape resulting at the end of the bending process being readily retained even under the influence of the weight of the holder and the lamp.
  • connection element with a small design, in which only a thin, bendable rod is visible. Due to the small and light design, the connection element can also be attached to light, sensitive structures. The small design also only slightly disturbs the view of objects lying behind the connection element and is also visually appealing.
  • the connecting element is preferably designed in the manner of a coaxial cable from high-frequency technology, but the core, as a bendable wire, is much thicker and is therefore unsuitable for high-frequency use.
  • the coaxial arrangement of the inner conductor, which is a deformable, but essentially rigid core, and the outer conductor ensures that the connecting element can be bent in any direction.
  • a large number of base and contact arrangements are known for coaxial cables, which can be used when using the connecting element.
  • the low-voltage lamp 10 shown in FIG. 1 has a power connection 12 and a lamp holder 14.
  • the power connection 12 consists of a connection element 16 and an adapter 18 which is pushed onto a two-pole busbar 20.
  • the connection element 16 is connected within the adapter 18 to two current collectors which are electrically isolated from one another and are each conductively connected to one pole of the busbar 20.
  • the lamp holder 14 arranged on the end of the connecting element 16 facing away from the adapter 18 has an inner current collector and an outer current collector, which are each connected to a pole of the connecting element 16.
  • Receiving sockets are provided on the lamp holder 14, each of which is provided for receiving a contact pin 22, 24 of a lamp 26.
  • connection element 16 shown in FIG. 1, which is shown in section in FIG. 2, is a coaxial cable.
  • inner conductor 28 it has a copper wire with a 1 mm diameter, which is embedded in an insulation 30 made of flexible plastic.
  • the insulation 30 has a scratch-resistant, water-repellent coating on its outside and is surrounded by an outer conductor 32 made of tinned tubing.
  • the inner conductor 28 is electrically connected to the lamp holder 14 with the receptacle for the contact pin 22 and the outer conductor 32 with the receptacle for the contact pin 24.
  • the tubular braid of the connection element 16 which is shown in a side view in FIG. 3, has a bare exterior without insulation and consists of fine wires, the thickness of which is approximately 0.03 to 0.1 mm.
  • the wires are interwoven as a flat bundle of three to ten, preferably six, wires, a single-braid weave preferably being used.
  • the tubular braid can also have a double-stranded binding made of wire bundles, adjacent bundles running parallel being interwoven in a mutually offset manner.
  • connection element 116 shown in FIG. 4 has a flexible inner conductor 128, which consists of a bundle of fine, twisted copper wires.
  • the inner conductor 128 is embedded in an electrical insulation 130 made of plastic.
  • a conductor element is provided as the outer conductor 132, which consists of a helically wound inner wire 140 and an outer wire 142 which runs essentially concentrically with the inner wire 140.
  • the coiled inner wire 140 has a circular cross section and is made of a rigid material which is not very flexible, for example steel.
  • the outer wire 142 on the other hand, has an essentially triangular shape and consists of a soft, easily deformable material, for example brass.
  • the outer wire With its two inner surfaces 144, the outer wire nestles into a helically running gap 146 formed by the coiled inner wire 140. In order to fit snugly against the inner wire 140, the inner surfaces 144 of the outer wire 142 are slightly curved.
  • the outer surface 148 is straight, so that the outer wire 142 has cylindrical jacket surfaces at least in sections.
  • connection element 116 When the connection element 116 is bent according to the second embodiment, the outer wire 142 and the inner wire 140 slide relative to one another. After bending, in which the outer wire 142 slides into an expanding gap 146 of the inner wire 140, the outer conductor 142 supports the inner conductor in a wedge-like manner so that it does not reset on its own.
