Definitions

  • the invention relates to a connector according to the preamble of claim 1.
  • Such connectors with a screw connection of the plug part to the socket part for securing against unintentional loosening of the plug connection are known in manifold designs, for example by the miniature circular connector with screw closure type "RKMWV " from Lumberg GmbH. This fuse also works permanently as long as the connector is not exposed to any or only slight or slow movements. However, if the plug connection is subject to a large number of in particular periodic impacts or a shaking movement, there is a great risk that the screw connection will loosen and the purpose of the union nut will no longer be fulfilled.
  • Such connectors are not suitable, for example, for use on machines with permanent vibration, such as use on machine valves.
  • Screw connections are already known in which a nut is secured against unscrewing due to shocks or vibrations by means of a spring washer (snap ring or corrugated spring washer).
  • the spring washer is always arranged between a contact surface of the screw and the end face of the nut facing it and is therefore necessarily designed as a separate part that can be lost when the screw connection is loosened, with all the associated disadvantages, from the more complex storage and assembly on site to the known problem that this part is often not at hand when needed.
  • German utility model G 93 01 171.7 describes a screw connection in which a radial toothing is formed on a contact carrier, which interacts with corresponding toothing of a union nut. This is to prevent an unintentional loosening of a screw connection.
  • the production of parts with radial toothing is complex since relatively narrow tolerances must also be observed.
  • the invention is therefore based on the object of developing a connector of the type mentioned in the simplest and cheapest possible manner in such a way that at the same time high vibration resistance and uncomplicated screwing of the union nut to the thread of the associated mating connector part is ensured.
  • the polygon is preferably an octagon, which enables the contact carrier to be produced easily.
  • two cams are preferably provided on the union nut, which are arranged offset by 180 on the inner circumference of the union nut.
  • the polygon is a nine-corner, wherein three cams are advantageously used, which are arranged around 120 on the inner circumference of the union nut.
  • the part of the contact carrier facing away from the plug-side end part can be injection-molded in a conventional manner with an injection-molded housing, the union nut being able to be placed loosely on the contact carrier before the overmolded material in the inventive configuration of the contact carrier and the union nut. This saves an additional step, namely pressing the union nut onto the contact carrier.
  • the union nut is preferably made from a die casting or with a cold impact tool.
  • the contact carrier is usually made of plastic.
  • the edges of the polygon are rounded to make it easier to turn the union nut with respect to the contact carrier. As a result, the degree of locking action between the contact carrier and the union nut can be selected.
  • the cams on the union nut are preferably designed to be elastic in order to facilitate rotation of the union nut with respect to the contact carrier.
  • the plug connector 1 consists of an injection molded housing 2 with a cable entry part 3 on the connection side, a contact carrier 6 made of plastic containing four contacts 5 and protruding from the housing 2, and a union nut 7 comprising the contact carrier 6.
  • the union nut 7 preferably has an internal thread 8 that can be screwed to a mating connector part, not shown, which has an adapted external thread, in order to hold the connector 1 together with the mating connector.
  • a shoulder 9 of the union nut engages behind an annular collar 10 of the contact carrier, so that the union nut 7 is rotatably arranged so that it cannot be lost.
  • the union nut has two projections or cams 11 which extend radially inwards from the inner circumference of the shoulder 9.
  • the contact carrier 6 has an upper end part 14 which extends from the ring collar 10 in the direction of the housing 2 and into it, and a lower end or plug part 16 which extends from the ring collar 10 in the direction of the mating connector, not shown.
  • the upper end part 14 of the contact carrier 6 is designed as a polygon, or here as an octagon with eight edge surfaces 18. During a rotation of the union nut 7 with respect to the contact carrier 6, therefore, a latching effect occurs on the edge surfaces 18 between adjacent edges or corners 19 of the contact carrier 6 and the cams 11 of the union nut 7.
  • the number of corners of the polygon and thus the flat edge surfaces 18 and the number of cams 11 can be freely selected. It is also possible to use a nine-corner in connection with three cams, the cams being provided at 120 ° from one another on the inner circumference of the shoulder of the union nut.
  • the corners of the polygon can be rounded, as indicated in FIG. 2, and / or the cams 11 on the inner circumference of the shoulder 9 of the union nut 7 and / or the contact carrier 6 can be made elastic his.
  • the lower end or plug part 16 of the contact carrier 6 is preferably round, but can have any shape that matches the mating connector.
  • the union nut 7 can be loosely placed on the upper end part 14 before the contact carrier 6 is overmolded, so that the union nut does not have to be pressed on from the connector part side 16 until afterwards in an additional operation.
  • the previously used shaft washers for securing the screw connection can be omitted, since this is ensured by the locking of the cams 11 on the union nut 7 with the side edges 18 of the contact carrier.
