Description

[0001] The invention relates to a busbar system. In particular, the invention relates to a busbar system with a busbar designed as a busbar, comprising a plurality of electrically conductive rails and an electrical component designed for connection to the busbar.

[0002] Such busbars are known, among others, from DE 21 32 133 A, DE 19 11 315 A and DE 38 11 128 A1, and in particular as three-phase busbars for the implementation of interior lighting concepts. For this purpose, one or more busbars connected to a 230 V power supply are attached to the ceiling of an interior space. One or more luminaires are then attached to these busbars and, by appropriate positioning along them, can ensure optimal illumination of the interior space.

[0003] One disadvantage of the known busbars is the lack of safety when handling them improperly, as well as their relatively large dimensions, which lead to a relatively large amount of material being used.

[0004] The object of the invention is therefore to create a busbar system that is easy to handle and has the smallest possible dimensions, in particular the lowest possible height.

[0005] This problem is solved according to the invention by the busbar system with the features of claim 1. The dependent claims describe advantageous embodiments of the invention.

[0006] One of the fundamental concepts of the invention is to not attach the electrical component directly to the busbar, but rather to connect it indirectly via a carriage inserted into the busbar. This ensures, particularly when the busbar is configured as a three-phase busbar, that electrical contact between the carriage and the protective conductor of the busbar is maintained at all times, and that the electrical conductors of the carriage only connect to the live conductor and the neutral conductor when the plug connection between the carriage and the electrical component is formed.

[0007] According to the invention, a busbar system is proposed comprising a busbar designed as a busbar with a plurality of electrically conductive rails, a carriage with a plurality of electrical conductors, each of whose ends is configured to contact one of the electrically conductive rails of the busbar and whose other ends together form a connector, an electrical component configured for connection to the busbar with a further connector cooperating with the connector of the carriage, wherein the busbar is configured to form a positive fit with the carriage for its slidable mounting along the longitudinal axis of the busbar, and one of the electrical conductors of the carriage contacts one of the conductive rails when it is mounted in the busbar.without the connector of the carriage forming a plug connection with the other connector of the electrical component, and without at least one other electrical conductor of the carriage contacting another of the conductive rails only when a plug connection is formed between the connector of the carriage and the other connector of the electrical component during its storage in the busbar.

[0008] The busbar is preferably designed as a three-phase busbar for connection to a 230 V mains supply, wherein the carriage in the busbar can be moved without voltage and is only fixed in its position by inserting the electrical component, whereby contact is simultaneously made to all electrical rails of the busbar required by the electrical component.

[0009] In particular, the three-phase busbar is designed so that the protective conductor is positioned opposite the connector of the carriage and thus opposite the electrical component, with the live conductor and the neutral conductor located laterally in the busbar, which is preferably designed as a C-profile. The carriage is mounted to the C-profile of the busbar in such a way that it can only be moved along the longitudinal axis of the busbar. Alternatively, the busbar can also be designed as a U-profile.

[0010] The carriage is freely movable within the busbar without being connected to the electrical component and is only connected to the grounding pole. In this state, the conductor poles (neutral and live) within the carriage are de-energized. By inserting and, preferably, locking the electrical component in the carriage, specifically by performing a relative rotational movement between the electrical component and the carriage, the carriage is preferably fixed in the busbar and secured against displacement, and the connection to the conductor poles is established, thus supplying the electrical component with 230 V from the busbar.

[0011] Finally, the busbar system is specifically designed for creating electrical networks within buildings, with the electrical component preferably being a grounded socket. The electrical component, in particular the socket or a USB port, can be inserted at any point in the busbar into the freely movable, de-energized carriage. The electrical component is secured to the carriage by rotation, thereby preventing it from being pulled out and providing access to the terminals. Only then is it possible to insert a plug into the socket (or USB port). When installing sockets within buildings, the busbar system according to the invention can preferably be used, allowing the sockets (or USB ports) to be easily positioned and securely installed.In particular, the power rail can be an integral part of a skirting board.

[0012] Preferably, the busbar is designed for connection to a low-voltage network and comprises one rail configured as a live conductor, one as a protective conductor, and one as a neutral conductor. As mentioned above, the busbar is further preferably designed as a C-profile and configured to accommodate the carriage within the C-profile. Alternatively, the busbar can also be designed as a U-profile.

[0013] Preferably, one of the electrical conductors of the slide makes contact with the protective conductor of the busbar when the slide is mounted in the busbar, without the connector of the slide forming a plug connection with the other connector of the electrical component. The ends of the electrical conductors of the slide intended for contacting the live conductor and the neutral conductor are most preferably mounted against the force of a spring, and when the plug connection is formed, these ends are displaced towards the live conductor and the neutral conductor, thus forming electrical contact with them.

[0014] It is also preferably provided that the formation of the plug connection of the connector of the slide with the further connector of the electrical component requires a relative rotational movement of the slide and the electrical component relative to each other, wherein the plug connection formed by the connector of the slide and the further connector of the electrical component is particularly preferably designed as a bayonet fitting.

[0015] The invention will be explained in more detail below with reference to a particularly preferred embodiment illustrated in the accompanying drawings. The drawings show: Fig. 1 a perspective view of a particularly preferred embodiment of the invention; Fig. 2 a frontal view of the in Fig. 1 of the embodiment shown (A) and a sectional view through the Fig. 1 illustrated embodiment (B); and Fig. 3 each a perspective view of the components forming the embodiment of a busbar system designed according to the invention, namely a particularly preferably designed busbar (A), a particularly preferably designed slide (B) and an adapter designed as a socket (C).

[0016] Fig. Figure 1 shows a perspective view of a particularly preferred embodiment of the invention. In particular, it shows Fig. 1 a perspective view of a particularly preferred busbar system 100, which has a busbar 10 designed as a busbar, a carriage 20 and an electrical component 30 designed for indirect connection to the busbar 10, wherein the electrical component 30 is designed as a protective contact socket in the example shown.

[0017] In Fig. 2, which shows a frontal view of the in Fig. 1 of the embodiment shown (A) and a sectional view through the Fig. As illustrated in the embodiment (B) shown, the busbar 10, which is designed as a busbar, has a plurality of electrically conductive rails 12, 14, 16. The carriage 20 is equipped with a plurality of electrical conductors, one end of each of which is configured to contact one of the electrically conductive rails 12, 14, 16 of the busbar 10. Finally, in Fig. 2 to recognize that the slide 20 and the electrical component 30 form a plug connection which, through the mediation of the slide 20, enables the electrical component 30 to be connected to the busbar 10.

[0018] This is how - Fig.Figure 3, based on the individual components busbar 10, carriage 20, and electrical component 30, shows that the carriage 20 has a connector 22 formed by the ends of the electrical conductors, and the electrical component 30 has a further connector 32 that cooperates with the connector 22. It is clearly visible that the carriage 20 can be inserted laterally into the busbar 10, forming a positive fit, so that the carriage 20 is movable along the longitudinal axis of the busbar 10. When the carriage 20 is mounted in the busbar 10, one of the electrical conductors of the carriage 20 contacts one of the conductive rails 14, without the connector 22 of the carriage 20 forming a plug connection with the further connector 32 of the electrical component 30.However, when the plug connection between slide 20 and electrical component 30 is established, the other electrical conductors of the slide 20 are brought into contact with the other conductive rails 12, 16, so that the electrical component 30 becomes fully functional.
