Definitions
- explosion-proof electrical equipment in particular lights or distribution boxes are used, which must be wired within monitored circuits.
- this wiring is usually done by the cable is connected to a terminal in the electrical equipment, led out by a cable entry on the housing of the equipment, inserted into the cable entry of the next resource and connected to the terminal, u.s.w.
- connection is very cumbersome and time-consuming, since for each resource must be opened, stripped cable and connected to the terminals and the equipment must be closed again.
- the invention is based on the problem of simplifying the wiring of explosion-proof equipment and shortening the assembly work hours and ensure that when merging or separating plug and socket possible sparks do not result in an explosion or the emergence of sparks is prevented from the outset. According to the present invention, this problem is solved by the features of claim 1.
- the contact pin or the contact socket to which the monitoring conductor (UL) of the circuit is connected with a voltage below the minimum ignition voltage is shorter than the other contact pins or contact sockets. The circuit is not closed until the OC contact pin gets in contact with the XL contact socket, and at this time all the other pins are already in the appropriate contact sockets.
- the circuit is already interrupted as soon as the ÜL contact pin or the ÜL contact socket no longer has contact with the ÜL contact socket or the ÜL contact pin, so that all other contacts can only be disconnected when they are already de-energized.
- the shortened design of the ÜL contact pin or the ÜL contact socket prevents the other contacts from being merged or disconnected under voltage and creating sparks which can ignite a possibly existing explosive atmosphere.
- the protective conductor (SL) contact pins of the connectors or the protective conductor (SL) contact sockets of the sockets are longer than the other contact pins or sockets.
- the equipment has at least one built-in from the outset in the housing and wired connector in flat design, which is designed either as a socket or as a plug.
- the Connectors are either an integral part of the equipment housing or later factory attached from the inside or outside of the equipment housing, eg screwed.
- the connectors have a spring-loaded cover flap, which must be opened before plugging in the cable and snapped back by the spring force when the cable has been pulled out.
- the connector socket or the connector plug of the last equipment at the end of a resource strand receives as a conclusion a wireless socket or a wireless plug with integrated end link.
- the monitoring of the circuit can optionally be performed by a lighting monitor with the modules insulation monitoring, protective conductor monitoring and / or Strebstillsetz sensible.
- Figure 1 shows schematically the structure of a linear luminaire with two integrated connectors.
- the housing 1 of the linear luminaire is provided at the head ends, each with a housing integrated in the connector 2a and 2b.
- a connector is formed as a socket 2a and 2b as a plug. Both connectors are wired to the provided terminal 3 in the linear luminaire housing.
- FIG. 2 shows schematically the wiring of several linear luminaires.
- the cables 4 are each at the two ends with a connector 5a and 5b equipped, wherein a connector is formed as a socket 5a and 5b as a plug.
- the cable end provided with the connector socket 5a is connected to the connector plug 2b of the field lamp, and the cable end provided with the connector plug 5b is connected to the connector socket 2a of the field lamp.
- Figures 3 and 4 show the inserts of the connector plug and connector socket with shortened executed ÜL contact socket and shortened executed ÜL contact pin.
- FIG. 5 A unique connector is shown in Figures 5 and 6. Three springs, two at the top and one at the bottom, of the plug shown in FIG. 6 engage in three corresponding grooves of the bush shown in FIG. This ensures that always ÜL contacts and SL contacts are interconnected.
- Figure 7 shows a closed connector with retaining clips.
