118939 ELECTRICAL SWITCHING SYSTEM 'w ^

The invention relates to an electrical switching arrangement as set forth in the preamble of claim 1.

5

The electrical connection arrangement according to the invention is particularly well suited for use in making electrical connections for mainly wooden houses and terraced houses. For other structures, the coupling arrangement is suitable for specific applications.

10

According to the prior art, said electrical connections are made manually by means of color codes with removable connecting elements. The disadvantage of prior art coupling arrangements is e.g. the slowness of the connections and the resulting costlyness 15, and the fact that manual switching generates a large number of switching errors which also cause safety problems. There are also drawbacks to the safety risks of possible bias connections of on-site electricity, for example, where there are many loose ends of electrical wires on the site, from which an electric shock can suddenly occur. Another disadvantage is the poor ergonomics, for example, when making electrical connections to the ceiling, you have to spend long periods in poor working position. A further disadvantage is that, according to the state of the art, a switching arrangement according to the state of the art in a group switching system can only have a maximum of eight outputs at a single point: T: 25. It also has the disadvantage of having a large number of wires and subsequent modifications. **, difficult adaptability.

It is an object of the present invention to eliminate the aforementioned disadvantages and to provide an intelligent, inexpensive, fast and simple switching arrangement mainly. ί for making electrical connections in wooden houses and terraced houses, whereby the wiring arrangement also minimizes wiring errors. For the coupling according to the invention, • ·. ·· *. The arrangement 35 is characterized by what is stated in the characterizing part of claim 1. Other preferred embodiments of the invention are characterized by what is set forth in the other claims.

An advantage of the switching arrangement according to the invention is the ease of making the switching, with the additional benefit of reducing the risk of accidents and improving safety, both during the construction site and in a pre-connected building. This is due to the fact that the number of misconnections is minimized and that there are, for example, a large number of free wire ends at the site. Furthermore, the switching arrangement according to the invention has the advantage of quick, inexpensive, simple and reliable connection, since the actual connection of the wires is completed elsewhere in ergonomic operating conditions. A further advantage is that the plug connector technology according to the invention makes it possible to spread more than eight outputs at a group switching level from a single point, which the conventional switching arrangement has had a maximum. It also has the advantage of providing intelligent functionality in the building's electrical system with operational flexibility, intelligent automatic advanced functions and additional security. In this case, for example, a switching arrangement monitors the premises of the building and automatically switches off the lights from the non-moving premises. Similarly, the switching arrangement 20 may, for example, monitor phase-by-phase power consumption and automatically reduce power consumption for a suitable period of time in an object where it is possible. The smart switching arrangement of the invention can also, for example, automatically switch off any electrical equipment that is left on the basis of a smoke alarm, such as · · V *. It also has the advantage that the switching arrangement can be commercialized so that the switching arrangement. * The product can be made in series.

For rooms 3, 4 and 5, a single room group is arranged divided into a 3-phase group by feeding a room group at each end the first end of the group wire 6 is connected by the plug 7 to the panel 2 and the other end likewise by the plug to the first smart switch box 9 of the room group. In the room group, one of the smart switch boxes 9, 10, 11 is connected. -15 with a group line extension 8 which divides the power supply from the first distribution box 9 of the room group to the other distribution boxes 10 and 11 of the room group.

The smart junction box 9 has plug connectors which, by means of plug-in connector technology, distribute other actuators in the room 3, such as sockets 12a and light switches 12b or the like, that require electrical supply to the power supply. In the example illustrated, rooms 3-5 are divided according to a phase group, each in its own phase, the first 25 for room 3, the second for room 4, and the third for room 5. In this case, all connections are taken care of they feature a smart switch box for each room 9, 10, 11 M · · .3. according to the smart connections selected on the circuit board.

Thus, 12 volts may be used, for example, for smoke detector-5 circuits that protect relays 17 for sockets. The circuit board 13 further has at least select switches 19 that select a suitable program for the central unit 15 to interconnect building actuators with the desired socket intelligence. Here, for example, the terminals 10 14b, through the light relays 16, switch on the lighting circuits according to the selection made by the selector switches 19.

The central unit 15 is programmed with features such as operating flexibility, energy saving and security. 15 In this case, an intelligent switching arrangement monitors the building's facilities and functions, and automatically intervenes by correcting the state of the monitored object as set or programmed. By means of intelligent functions, for example, the switching arrangement may automatically switch off the lights 20 from a state of inactivity for a short period of time. The intelligent switching arrangement according to the invention can also, for example on the basis of a smoke alarm, switch off electrical devices left over by relay and logic controlled circuits, such as sockets, stove, sauna heater, individual heating systems, etc. Similarly, the circuit board 13 can be equipped with * fault and overcurrent protection, for example, by: ***: measuring the current through the relay 17 of the relay 17 for the sockets 14a, whereby the current: , · .30, when the relay is raised above normal, the relay is triggered.
