Definitions

  • the invention relates to an explosion-proof connection device with a plug and socket (plug connection), the plug having a plug housing with at least two contact elements and the socket having a plug housing with at least two corresponding plug elements arranged therein.
  • the invention has for its object to improve an explosion-proof connection device of the type mentioned in such a way that the disconnection of the connection can be carried out in a simple manner without de-energizing appropriate devices and without involving specialists.
  • plug housing and socket housing are automatically held in a retention position with contact elements and insertion elements already separated from one another during the disconnection of their connection, in the retention position between the housings and Elements a substantially closed interior is formed.
  • the explosion-proof connection device according to the invention therefore has an intermediate position between the completely separate connection and the completely established connection, the so-called retention position.
  • the contact elements and plug-in elements are separated from one another to such an extent that there is no electrical connection between them.
  • connection device If, for example, an explosive gas or the like has penetrated into the connection device and could be ignited by a spark which may occur when the contact elements and plug-in elements are electrically separated, the plug housing and socket housing are held in the retention position and the mechanical connection is not completely released. As a result, the explosion cannot continue to the outside of the connecting device, where a larger explosion and greater damage could be triggered by the ignition spark when the elements are separated.
  • the interior formed in the retention position between the socket housing and the connector housing is relatively small and essentially closed off from the outside, so that at most gas or the like which has penetrated from the outside in this interior could be ignited by such a spark and the explosion from the interior does not occur to the outside the connection device can continue.
  • connection device according to the invention can be used without disconnecting the voltage and without using specially trained maintenance personnel or the like.
  • plug housings and socket housings in the retention position and their automatic arrangement at this point when the connection is released can be done in different ways.
  • the plug housing and the socket housing can be locked together in the retention position. This locking engagement is made automatically when the connection between sockets and plugs is disconnected.
  • the locking engagement can be released directly by hand or with the aid of conventional tools in a simple manner.
  • An example of a corresponding locking device is a locking element on the plug housing and a counter-locking element on the socket housing. It should be noted here that such a latching or counter-latching element does not have to be physically formed from one element, but can comprise several individual elements. This means that each individual detent element is engaged with each counter detent element when the plug and socket are separated from one another to the extent that the retention position is reached.
  • Locking element and counter-locking element can also be arranged in the reverse manner on the plug and socket housing.
  • locking elements are spring-loaded locking cams, locking tongues, other elastically deflectable locking elements or the like.
  • the latching element can be a latching projection protruding from an inner wall of the plug housing and the counter-latching element can be a latching recess arranged in an outer wall of the socket housing.

Abstract

L'invention concerne un dispositif de raccordement antidéflagrant (1) composé d'une fiche mâle (2) et d'une prise (3), ladite fiche mâle (2) présentant un boîtier de fiche (4) comportant au moins deux éléments de contact (5, 6), et la prise (3) présentant un boîtier de prise (7) comportant au moins deux éléments d'enfichage (8, 9) correspondants. L'invention vise à améliorer un tel dispositif de raccordement antidéflagrant de manière que la séparation du raccordement peut être réalisée simplement sans mise hors-tension des appareils correspondants, et sans recours à du personnel spécialisé. A cet effet, le boîtier de fiche (4) et le boîtier de prise (7) sont maintenus de manière autonome en position de retenue (10) avant détachage complet lorsque les éléments de contact (5, 6) et les éléments d'enfichage (8, 9) sont séparés électriquement, un espace intérieur (11) essentiellement fermé vers l'extérieur en position de retenue (10) étant formé entre les boîtiers (4, 7) et les éléments (5, 6 ; 8, 9).
