Description

Arrangement of a fitting element for mounting a

Electricity consumer on a lightweight board, lightweight board,

Fitting element and power supply component

The present invention relates to an arrangement of at least one fitting element for mounting a power consumer to a lightweight board according to the preamble of claim 1 and a lightweight board according to claim 14, a fitting element according to claim 15 and a power supply component according to claim 16.

Such arrangements are known in the art. In particular, lightweight panels with differently shaped middle layers of foams, honeycombs or the like are well suited for accommodating functional elements. In the power supply of power consumers mounted on the panel, the supply of the current is difficult in that through the entire lightweight panel a power line to the

Electricity consumers must be laid down.

Although multilayer plates are known, for example from FR 2 856 526, or WO 2005/029649, which have an electrically conductive contact layer. However, the contact elements disclosed here, on the one hand, for supplying the electrically conductive contact layer and, on the other hand, for collecting current via contact elements to be driven into the plate, are not suitable for this purpose

Lightweight panels, because on the one hand to hit the plate

Contact elements when driving into the hard surface of the lightweight board due to the thereby displaced material would lead to cracks in the lightweight panel and on the other hand, the exact positioning of the contact element for contacting the contact layer can not be ensured. Also, the contact element disclosed in FR 2 856 526 for supplying the electrically conductive contact layer, in which the electrically conductive contact layer is surrounded by a clamp and clamped, would not find the required support in a lightweight board, Since the lightweight panels are often produced in large format and are then brought, for example by sawing to the required size, the installation of such power cables can not be made during the manufacture of lightweight board. To a power line to a

Current consumers, such as a lighting element to lead, currently has the middle class, such as a paper honeycomb or a polyurethane foam, be cleared on the entire power line route. Subsequently, the power line must be placed through the cleared area to the previously introduced breakthrough in the lightweight board for the power consumers in the cover plate. The power line is then connected to the power consumer. Thereafter, the power consumers can be used in the lightweight board and fixed. In order to introduce the power line directed to the power consumers in the middle layer of the lightweight board, usually a pipe is driven through the middle layer to the position at which the

Power consumers to be mounted. The pipe is driven with the tethered pipe until it breaks through the middle layer. At the breakthrough, the line is received and pulled through the breakthrough to the outside. The pipe is removed again from the lightweight board. Object of the present invention is an arrangement of a

Fitting element for mounting a power consumer anywhere on a lightweight board to provide, with the above-mentioned disadvantages are eliminated and with the particular simple and cost-effective installation of a power consumer is made possible on a lightweight board.

Another object is to provide a suitable for the fulfillment of the above task fitting element, a lightweight construction plate and a power supply part.

This object is achieved by an arrangement of at least one fitting element for mounting a power consumer to a lightweight panel with the

Characteristics of claim 1 a lightweight board with the features of

Conductor layers each be arranged an insulating layer of an electrical insulator. This is particularly necessary if the cover plates of a conductive material or material with poor electrical

Insulation properties exist or are flammable. Furthermore, for ontaktierung multipole contacts also several

Sequences of conductor layer and insulation layer are provided. Also, an intermediate layer similar to the cover plates with conductor layer can be provided in particular for the realization of a protective contact. The arrangement according to the invention is not based on a two-pole system

limited. With the arrangement according to the invention can be any number

Contacts are realized. Thus, e.g. The materials used in the intermediate layer are designed as electrical insulators, alternatively the conductor layer is delimited to the middle layer with an insulating layer. In this case, the contacts of the fitting element are provided with current collectors, for example, with tips that penetrate the insulation layer.

An arrangement of the at least two conductor layers, isolated from each other, in a plane of the lightweight board is also conceivable. These conductor layers are designed, for example, alternately with insulating layers. The

contacting fitting element then no longer has to

rich side opposite the middle layer, however, then again a precise positioning of the fitting element on the conductor layers is necessary.

With such a lightweight board and a corresponding

Fitting element is given the opportunity to mount a power consumer at any point of the lightweight board. As a result, at the time of manufacture of the lightweight panel is not yet known, at which positions such a power consumer is to be placed. The arrangement is suitable for all designed in the manner specified lightweight panels, as they

According to one embodiment, the conductor layers are mounted on the middle layer facing sides of the cover plates and in particular as a braid, film, lacquer layer or adhesive layer. In this design, a power consumer can be accommodated anywhere on the plate, without a channel for carrying a power cable to the

Electricity consumers have to lay. According to a further embodiment, each of the pantograph of the at least one Beschiagelements resiliently abuts one of the conductor layers, so that the fitting element with which the current consumer is mounted on the lightweight board, even with not exactly aligned placement of the

Fitting element in the lightweight board safely comes into contact with the conductor layers.

Any implementation in the cover plates and the support and / or decorative edges for the fitting elements, power consumers and / or the

Power supply components are sealed against the environment, especially against the ingress of liquids or moisture. For example, by introducing adhesive, resin, or potting compound in the

Connecting points between the lightweight panels and the fitting elements, power consumers and / or the power supply component achieved a seal. Furthermore, seals in the form of sealing rings made of elastic material between the lightweight panels and the fitting elements,

Power consumers and / or the power supply component to be arranged. Ingress of moisture is thus prevented. There is therefore no danger to the user and electrical consumers as a result of improper use

Current exposure. The IP protection classes find in the implementation of the

Arrangement according to the invention, just as the fire protection in the selection of the materials used is taken into account. Also An electromagnetic compatibility (EMC) is ensured in the implementation of the arrangement according to the invention with AC voltage.

According to a further embodiment, a power supply component connected to a power source is mounted in the lightweight board. This power supply component is preferably formed with spring-mounted and the conductor layers contacting electrical contact elements, so that the

Power supply component in the production of lightweight board at a preferably easily accessible location, for example, in a front side of the lightweight panel, can be mounted and so supplied the entire lightweight panel with power.

Preferably, the arrangement according to the invention with low voltage 12 V or 24 V is operated. Furthermore, direct current is preferably provided for the operation of the arrangement according to the invention.

It is also conceivable to use a low voltage of, for example, 230 V for the operation of the consumer at 60 Hz, for example

In the case of the operation according to the invention, contact protection is provided to protect the users, in particular when operating with low voltage that a likelihood of confusion between different

Voltage ranges and reverse polarity protection is given. An adaptation of different voltage ranges is thus taken into account.
