Definitions
- the invention relates to a functional extra-low voltage power supply device, which is provided with at least one busbar, which has mutually parallel, isolatingly connected current conductors which can be contacted with current collectors to which current consumers can be connected, the busbar in the form of at least one longitudinal slot having profile is formed, and at least one current conductor is arranged in this longitudinal slot.
- Such power supply devices are provided in particular for the supply of lights.
- Known power supply devices for extra-low voltage usually have one or more busbars which are connected to a transformer which converts the AC mains voltage to extra-low voltage, e.g. 12V formed, with which then low voltage lights, e.g. Halogen lights are supplied.
- the busbars of the known devices are not insulated from the outside, which is not dangerous with regard to the possibility of touching them because the voltage used is low.
- the possibility that metal objects come into contact with both conductors of a conductor rail and cause short circuits can cause damage to the device and also to the environment.
- DE 39 19 201 A describes a busbar with this disadvantage, in which two bars forming the busbar are connected to one another by means of plastic bolts. The rods are arranged so that they are easily accessible from all sides, so that the risk of a short circuit is very high.
- a low-voltage busbar in the form of a metal tube with a longitudinal slot which carries a copper wire covered with an insulating strip inside; with which a spring-loaded contact pin is brought into contact.
- the current collector is fixed to the metal tube by means of a rectangular plate which is molded onto a cylinder which is connected to the tube of the lighting fixture. During assembly, the plate is inserted with its narrow side into the longitudinal slot of the rail and then rotated by 90 ° so that it adheres to the undercut fertilize the longitudinal slot supports.
- a sleeve which can be pushed over the cylinder is arranged and which is coupled to the tube of the lighting body via a threaded bushing, the plate being pressed against the undercuts by turning the threaded bushing.
- the contact pin is passed through in an electrically insulated manner through a bore in the plate and in the journal of the cylinder. It is also disadvantageous here that the plate bends when the threaded bushing is overtightened and comes into contact with the contact pin with the edge of the bore, so that a short circuit results.
- the aim of the invention is to provide a busbar of the type mentioned in the introduction, in which disadvantages, as are present in the known busbars, are avoided.
- a simple contact should be possible with a simple structure, and the risk of short circuits should also be practically excluded.
- the individual current collectors have a thread as a mechanical holding element which, by coming into engagement with the opposite side walls of the longitudinal slot, can be screwed into this longitudinal slot.
- the current rail can have a simple structure overall and can be easily manufactured with relatively little effort.
- a current conductor is arranged on the bottom part of the longitudinal slot. This measure ensures that the conductor is well protected within the conductor rail.
- the profile forming the busbar has an approximately H-shaped cross section with longitudinal slots directed away from one another in the profile, in which current conductors are arranged.
- This design of the conductor rail also offers extended design options.
- a particularly compact and simple construction of the busbar and the current collectors can be achieved in that the profile forming the busbar is a metal profile and the at least one current conductor is arranged insulated in the longitudinal slot (s).
- the insulation of the current conductor leaves at least one side of the current conductor accessible from the longitudinal slot.
- the current conductor or conductors is or are insulated on all sides with soft plastic or soft rubber. To draw current, a pin penetrating the insulation is led to the relevant current conductor.
- the conductor provided with insulation is arranged in a groove provided in the wall of the longitudinal slot, provided with lateral undercuts and extending in the longitudinal direction of the profile, and is held in the groove in a form-fitting manner by these undercuts is.
- the current conductor provided with insulation has an approximately circular cross section and is arranged in a form-fitting manner in a circular sector-shaped groove in the wall of the longitudinal slot, which is at an angle of more than 180 ° with respect to the geometric axis is sufficient.
- Conventional insulated wires can be used as the primary material for the current conductors, which are available in practically everywhere in various dimensions and designs, which results in low production costs.
- the profile forming the busbar is a plastic profile in which several, e.g. two current conductors are arranged insulated from one another.
- the opposite side walls of the longitudinal slot (s) corresponding to the pitch of the thread of the holding element have successive grooves in the depth direction of the longitudinal slot (s), into which the thread at Screwing engages in the relevant longitudinal slot.
- the threaded elements of the current collectors can be easily moved in the longitudinal slots following the slot direction over any distances to the desired position and then screwed tight, since the threads engage in the grooves.
- a particularly preferred, structurally extremely simple design of the pantograph is obtained if the thread of the pantograph carries at the end a contact provided for contacting a current conductor arranged in the longitudinal slot, which is arranged in an insulated manner and is connected to a conductor leading out of the longitudinal slot area. This creates a good electrically conductive connection between the current conductor and the current collector.
- the contact is in the form of a tip axially projecting from the end face of the thread. This results in a particularly favorable contact between the current collector and a e.g. current conductor covered with soft plastic or soft rubber, since the tip penetrates its insulation and penetrates into the current conductor.
- the contact is in the form of one or more contact fingers (s) which can be pivoted or swiveled radially about the geometric thread axis.
- This embodiment is advantageous if current conductors are arranged on the side wall of the longitudinal slot of the current rail.
- pantograph is a carrier for a lamp.
