Definitions

  • the invention relates to pressurized water-tight plug-in contact connections with a two-part plug-in contact housing provided with electrical leads, or sockets, of which at least one housing part consists essentially of rubber-elastic material, with a first housing part having an outer, essentially cylindrical outer surface and a second housing part. which has a protruding sleeve with an inner encircling surface which can be pushed over the outer surface of the first housing part, and with annular seals provided between these two surfaces at a longitudinal distance between them with annular beads engaging in annular grooves.
  • the invention has for its object to further develop the pressurized water-tight plug contact connection of the type mentioned that despite a more comfortable handling when coupling both connecting parts, a perfect seal is guaranteed.
  • the plug contact connection according to the invention in which this object is achieved, is essentially characterized in that at least one in one housing part Central contact spring bushing or a central plug pin and a central contact bushing concentrically surrounding this or these are inserted so that in the other housing part at least one central plug pin which can be pushed into the central contact spring bushing or a central contact spring bush which can be pushed onto the central plug pin and one on the middle one Contact socket push-on outer contact socket are embedded in a pressure-tight manner and that in one housing part the central contact socket is provided with spaced surrounding grooves for receiving O-rings, which in the connected connection state rests on the cylindrical outer surface of the outer contact socket of the other housing part.
  • the grooves for receiving the O-rings are formed on the inner wall of a tubular metallic body which is formed in one piece with the middle contact socket. In this way, the position of the O-rings with respect to the outer surface of the outer contact socket, which enters between the inner wall of the tubular metallic body and the middle contact socket, is largely fixed, thus increasing pressure-tightness security. It has proven to be very advantageous in terms of construction if the metallic outer contact socket is connected to a sleeve body of insulating material enclosing them to form a unit, the cylindrical outer surface of which cooperates with the O-rings.
  • a particularly expedient design of the plug contact connection is achieved in a further embodiment if the central contact spring socket or the central plug pin and the central contact socket concentrically surrounding it into the first housing part comprising the essentially cylindrical lateral surface and the central plug pin or the central contact spring socket and the outer one Contact socket are embedded in the second housing part having the above sleeve.
  • the sleeve body made of insulating material surrounding the metallic outer contact socket is provided with a molded, approximately axially parallel cylindrical extension, which has the fixing in the rubber-elastic material of the associated housing part favoring ring grooves.
  • the mechanical and electrical strength are further increased by the fact that the central contact spring bushing and / or the central plug pin are each embedded in an insulating base. It is advantageous if the insulating base of the central connector pin is provided with a circumferential recess which favors its fixing in the rubber-elastic material of the housing part.
  • the illustrated water pressure-tight plug-in connection comprises a plug-in contact housing with two housing parts 1 and 2 made of rubber-elastic material, e.g. seawater-resistant elastomer or neoprene. These housing parts 1 and 2 each contain electrical pins 3, 4 and 5, 6 provided with plug pins or sockets.
  • the one housing part 2 comprises a central plug pin 7 and a central contact socket 8 concentrically surrounding it.
  • a central contact spring socket 9 which can be pushed onto the central plug pin 7 and an outer contact socket which can be pushed onto the middle contact socket 8 10 stored pressure-tight.
  • the plug pin 7 is connected to the electrical supply line 6, the contact socket 8 to the electrical supply line 5, the central contact spring socket 9 to the electrical supply line 4 and the outer contact spring socket 10 to the electrical supply line 3.
  • the central contact spring bushing 9 is equipped in a manner not shown in detail, and also the outer contact bushing 10 with a large number of radially inwardly curved contact springs 11.
  • each housing part comprises only one contact spring bushing 1 or contact bushing 10 with contact springs 11.
  • the plug pin 7 is thus, at a short distance from a protruding insulating sleeve 7 ', surrounded by the concentrically arranged outer contact socket 10, while in the housing part 2
  • the central contact spring socket 9 is mounted in a pressure-tight manner concentrically with the middle contact socket 8.
  • housing part 1 comprises a projecting sleeve 12 with an inner enclosing surface 13 with which it can be pushed over a cylindrical outer surface 14 of the other housing part 2.
  • ring seals are provided, which are formed by annular beads 15, 16 on the enclosing surface 13 and annular grooves 17, 18 adapted to them on the lateral surface 14.
  • the outer annular bead 16 is hook-shaped in cross section.
  • the associated annular groove 18 is provided with an adapted stop edge 19.
  • the enclosing surface 13 and the outer surface 14 are shown cylindrically. In order to facilitate the insertion of the two areas into one another, they can also have a slightly conical shape. The prerequisite is that the annular beads 15, 16 engage properly in the annular grooves 17, 18 in the inserted state and ensure sufficient mechanical retention of the connection.
  • O-rings 20, 21 which are mounted in grooves in one housing part 2 and, in the inserted connection state, also rest on the cylindrical outer surface 22 of the outer contact socket 10 of the other housing part 1.
  • the grooves for receiving the O-rings 20, 21 are formed on the inner wall of a tubular metallic body 33 which is formed in one piece with the central contact socket 8.
  • the metallic outer contact socket 10 is made with a sleeve body 24 surrounding it temperature-resistant insulating plastic connected to a unit, the cylindrical outer surface 22 cooperates with the O-rings 20, 21.
  • the central contact spring socket 9 and the central plug pin 7 are each embedded in an insulating base 28, 29.
  • the insulating base 29 of the central plug pin 7 is provided with a circumferential recess 30 which favors its fixing in the rubber-elastic material of the housing part 2.
