  • the corresponding power supply to the other or the other devices is not interrupted.
  • the corresponding second contact depression with the further contact elements can also be used, except for the electrical supply of further devices for connecting a measuring device, in order to check and monitor it during the operation of the corresponding device.
  • the two contact recesses and the corresponding contact elements are usually carried out in the same way, so that they are both also used in the same way. There may be provided two or more contact elements, depending on the application.
  • the contact elements may be formed as contact pins, which are inserted into corresponding contact sockets on the respective device. It is also the reverse training possible, i. that the contact elements of the plug contact device are designed as contact sockets.
  • the further contact elements of the second contact recess may be formed analogously to the first contact elements of the first contact recess, so that they can also be used to connect a particular further electrical device. But it can also be used for the second contact elements contact sockets, for example, if the first contact elements are designed as contact pins.
  • one of the contact recesses and the contact elements arranged there are not used, they can be covered by a particularly explosion-proof protective cover, which can be placed detachably at the corresponding point of the plug-in housing.
  • data can be exchangeable via the first and further contact elements.
  • the corresponding measuring device can be connected in this context to the first or further contact elements.
  • the second contact recess may be arranged substantially perpendicular to the first contact recess on the plug housing.
  • the second contact recess in particular projects laterally and inclined towards the supply line from the plug housing or that further contact recesses are provided.
  • an electrical circuit for monitoring functions of the plug contact device and / or the voltage or power supply the or the connected device is arranged.
  • This corresponding electrical circuit is integrated directly in the plug housing and may have a corresponding memory device which collects, for example, data during use of the device or the plug contact device, which are retrievable when connecting a corresponding measuring and monitoring device.
  • a simple way to de-energize the electrical connection between the plug contact device and the connected device can be seen in that the plug contact device is held in already electrically disconnected from the device contact elements on the device in a retaining position, in which between the plug contact device and device a substantially outwardly closed interior is formed.
  • This interior is relatively small, so that at most in this interior from the outside penetrated gas or the like in the hazardous area could be ignited by a spark, but this explosion can not continue from the interior to the outside of the plug contact device.
  • no voltage release must be done and without the use of specially trained maintenance personnel or the like, the plug contact device can be solved by the device.
  • Fig. 1 is a schematic diagram of a known plug contact device 1 is shown.
  • This comprises a plug housing 6, into which a supply line 3 is led. Opposite to the supply line 3, the plug housing 6 on a contact recess 4, in which at least two contact elements 5 are arranged, see Fig. 3. In the interior of the plug housing 6, the contact elements 5 are connected to the supply line 3.
  • the plug contact device 14 is used for plugging or plugging in or into a corresponding plug contact device 1, which is connected to an electrical device, such as a field device 2, 10 or attached to its housing.
  • the plug-in contact device is designed to be explosion-proof, so that even without voltage disconnecting a peeling or plugging the plug contact device 1 in potentially explosive areas is possible.
  • FIG. 2 shows a representation analogous to FIG. 1 of a first embodiment of a plug contact device 1 according to the invention. This differs from the previously known plug contact device according to FIG. 1 by an additional second contact recess 7 laterally on the plug housing 6 and substantially perpendicular to the first contact recess 4. In the second contact recess 7, a corresponding number of further contact elements 8 are arranged analogously to the first contact recess 4. The number of contact elements is at least two.
  • the plug contact device 1 according to the invention for a further embodiment is shown in a longitudinal section. This differs from the embodiment of FIG. 2 in particular by the obliquely laterally projecting in the direction of the supply line 3 portion of the plug housing 6, in which the second contact recess 7 is formed with corresponding further contact elements 8.
  • connection devices 15 for example in the form of connecting wires, to the first contact elements designed as contact sockets 9.
  • first contact elements are arranged within the first contact recess 4, which is indicated in principle in Fig. 3 and dashed lines.
  • second contact recess 7 is constructed with further contact elements 8, wherein these may also be formed as corresponding contact sockets 9 or as contact pins.
  • the further contact elements 8 are connected in parallel with the supply line 3 or the corresponding connection devices 15 with respect to the first contact elements 5. This makes it possible to use the plug contact device 1 at the same time for the electrical supply of two electrical devices 2, 10, which are, for example, field devices in a hazardous area. Between the further contact elements 8 and the supply line 3, an electronic circuit 13 is provided.
