  • Control slide inserted. These are clearly visible to the operator and can only be moved or displaced into an end position when the plug connection is in the defined plugged position.

  • a CPA and a connector arrangement with a CPA are known from DE 10 2014 206 431 A1.
  • the invention is based on the knowledge that the defined plug-in position of a plug-in connection should be reliably recognized by an operator or a fitter and that an interior of a plug-in connector arrangement consisting of a plug-in connector or plug and mating plug-in connector or mating plug should be designed to be media-tight from an outside space when plugged together .
  • This is intended on the one hand to bring about a secure electrical connection and on the other hand to ensure the durability of the electrical connection in the interior.
  • the longevity can be achieved by preventing or at least greatly preventing the entry of fluid media (e.g. liquids or gases) as well as dirt, particles and dirt.
  • fluid media e.g. liquids or gases
  • Insertion resistance or the insertion force is noticeably increased.
  • Insertion force of the connector when mating with the mating connector should be as low as possible. An increase in the insertion force when plugging together due to a tightly enclosed volume of air in the interior should be avoided as far as possible. In the same way, when unplugging connectors and
  • the connector has a housing with an interior space and a contact element arranged in the interior space.
  • the connector also has a Connector Position Assurance (CPA).

  • a sealing element or a sealing means is provided on the CPA, the pressure compensation element being sealed against the outside space by the sealing element in the second position.
  • the connector is intended to be equipped with a
  • the sealing element does not have to have a valve function for this.
  • the connector must first remove the CPA from the second position (e.g. into the second position).
  • Pressure compensation elements can be released again.
  • the CPA can be attached to the housing in a captive and relocatable manner. You can e.g. be performed in a setting.
  • Plugging together with the mating connector enables pressure equalization and thus the exchange of fluid flows, but at the same time it is ensured that the interior is sealed against the exterior after the plugging process has been completed and the CPA has been actuated.
  • the CPA advantageously fulfills a multiple function:
  • Sealing means the (media) tight sealing of the interior from the exterior by sealing the pressure compensation element;
  • contact elements can be arranged in the interior, e.g. two or more than two contact elements.
  • a contact chamber which is designed to accommodate the contact element, can be arranged in the interior of the connector. It goes without saying that several contact chambers can also be arranged in the interior. There can be several

  • a single contact element can also be arranged in each contact chamber.
  • the contact element can, for example, be latched in the contact chamber.

  • a locking lance on a wall of the contact chamber may be possible, which then engages in an undercut of the contact element.
  • the contact element can e.g. have one or more contact lamellas, which bring about reliable electrical contact with an inserted or adjacently arranged mating contact element.
  • the contact element (or the contact elements) can be used to contact a

  • the mating contact element can e.g. be designed as a pin, a contact knife or the like.
  • the mating contact element can also be designed in the form of a female contact and the contact element in the form of a male contact.
  • Sealing elements can be provided on the connector or on the mating connector. These further sealing elements can e.g. be arranged in the area of cable passages through the housing. A radial seal can also be provided, which is arranged between the housing walls of the plug connector and mating plug connector when they are plugged together. Alternatively, a seal can also be effected by an external sealing element.
  • a radial direction is to be understood as a direction perpendicular to the insertion direction and a circumferential direction is a direction that extends circumferentially around the insertion direction, unless otherwise stated in the text.
  • Connector and mating connector are correctly plugged together.
  • Correct plugging together e.g. an end position, an end latching position, etc. (thus the defined plug-in position) can be reliably recognized even under poor visibility or under cramped installation conditions, since the CPA can only be moved when the defined plug-in position has been reached.
  • the CPA can e.g. are initially in the first position before the connector is mated with the mating connector.
  • a mechanical lock can be provided which prevents the CPA from being shifted into the second position as long as the defined plug-in position has not yet been reached.

  • Mating connector is.
  • the opening is located, for example, in the sealed part of the interior, that is to say beyond a radial seal that is present, for example.
  • the fact that the opening is covered by a membrane, the membrane being designed to be waterproof but gas-permeable, has the advantageous effect that the risk of liquids or dirt, dirt or dust entering the interior is minimized as long as the CPA is not yet is shifted to the second position. This is advantageous in the interior, for example when transporting the connector or when
  • this advantageously prevents dirt, dirt, particles or even liquid from getting through the opening from the outside into the interior after the CPA has been moved from the second position to the first position when the plug connection is opened.

  • a sealing element can be manufactured particularly inexpensively, since the seal is ensured regardless of the size tolerance of the sealing means as long as the edge of the opening is securely covered. In the event of an overpressure suddenly occurring in the interior, a sealing means designed in this way can also advantageously act in the manner of an overpressure valve.
  • the sealing element is designed in the manner of a sleeve, wherein in the second position of the CPA the sealing element over the Opening is turned over.
  • the sealing element is slipped over the edge of the opening and completely covers the opening, like a crown cap for example the pouring opening of a bottle, the sealing function here additionally being effected, for example, by the inner wall of the sleeve resting against the outer wall of the opening can.

  • the sealing element can be designed as an O-ring, with the sealing element resting on the housing in the second position of the CPA and completely surrounding the edge of the opening.
  • This provides a particularly simple and inexpensive sealant.
  • O-rings are available in a wide variety of materials,

  • the connecting piece can, however, also be made straight, so that the further opening points in the same direction as the opening in the housing.
  • the connecting piece can thus cause e.g. a distance to the sealant disposed on the CPA is reduced. It can also advantageously be effected that the further opening is aligned in such a way that the sealing means can reliably seal off the interior from the exterior when the CPA is moved into the second position.
  • the nozzle can facilitate the function of the sealing concept or even enable it at all without having to make extensive redesigns of the connector. In this way, the concept can also be beneficial in existing ones

Abstract

La présente invention concerne un connecteur enfichable (1) à enficher le long d'une direction d'enfichage (E) avec un connecteur enfichable complémentaire (60). Le connecteur enfichable (1) comprend un boîtier (2) ayant un espace interne (3) et un élément de contact (20) disposé dans l'espace interne (3). Le connecteur enfichable (1) comprend en outre une assurance de position de connecteur (CPA, 4). Le boîtier (2) comprend un élément de compensation de pression (5) pour compenser la pression de l'espace interne (3) par rapport à un espace externe (6) du boîtier (2). La CPA (4) est disposée au niveau du boîtier (2) et peut être déplacée relativement au boîtier (2) entre une première position (P1) et une seconde position (P2). Un élément d'étanchéité (30) est disposé au niveau de la CPA (4) et, dans la seconde position (P2), l'élément de compensation de pression (5) est séparé de l'espace externe (6) par l'élément d'étanchéité (30).
