  • the lid thus closes the insertion of the socket housing in the non-use case, ie when no plug of the trailer circuit is plugged into the socket, sealing off.
  • Equivalent in meaning of the application with a plug of the trailer circuit is a plug adapter which is inserted between a plug of the trailer circuit and the socket to connect different connection systems with each other. Often, such a plug adapter remains in practice, for example. For convenience, always plugged into the socket, which is not desirable in the rule.
  • An inserted plug adapter is understood in the meaning of the application as an inserted plug of the trailer circuit, also irrespective of whether the plug of the trailer circuit itself is plugged into the plug adapter.
  • the socket according to the invention can be fully assembled or supplied as a kit or items to this kit by, for example, the socket housing and a contact carrier insert are supplied separately, wherein the contact carrier insert forms the contact carrier can be arranged in the socket housing.
  • the reason for this form of delivery of the socket according to the invention is the preparation of the installation by a clothing manufacturer, who engages in the contact carrier insert connected to the connection lines, if necessary, and thus provides a finished harness for final assembly.
  • the contact carrier insert is then locked in the socket housing.
  • the socket housing and the contact carrier insert are preferably connected to one another in a sealing manner by interposing a seal.
  • the contact carrier insert and the socket can also be welded together, for example, by the manufacturer or the assembler, or otherwise connected in a materially cohesive manner in order to achieve a seal between the contact carrier insert and the socket.
  • integrally formed sockets in which the socket housing and the contact carrier are in one piece for example.
  • the contacts or parts of the contacts are usually inserted by the garment maker or during installation in the contact carrier.

  • a micro-switch can, for example, be arranged to save space in a recess of the contact insert. Such an arrangement is in the EP 2 037 545 A2 shown.
  • a major disadvantage is that the switch with the plunger protrudes into the insertion space of the plug and for this purpose a passage from the insertion of the plug must be provided in the contact space of the socket, can penetrate through the moisture in the connection area of the socket. Since the Einsteckraum in operation can not be completely sealed, there is a problem with such sockets in the long term that moisture penetrates into the connection area and by leakage currents or short circuits the Function of the trailer circuit and / or the electrical system of the motor vehicle disturbs or damaged.
  • Another disadvantage is that only the insertion of a plug is detected in the socket, but not a situation in which the lid for closing the Einstellö réelle when not in use, for example.

By switching the relay, the contact of the first connection part is first connected to the circuit.

  • the seal has a faulty element which is biased such that the seal without acting on a force on the spring element has a non-planar resting on the bottom of the Einsteckraums portion, and that the magnet in which no force on the spring element not plan is placed on the bottom of the insertion space resting portion of the seal.
  • the switchable contact of the plug sensor is then placed in the bottom of the insertion space opposite the portion of the gasket with the magnet. This ensures that when the plug is not plugged in the magnet is so far away from the switchable contact that there is no operative connection and the switchable contact switches only when the seal pressed by the inserted plug against the force of the spring element flat on the bottom of the insertion space becomes.
