Definitions

  • the invention relates to a receptacle housing for a plug element and/or mating plug element of an electrical plug-in connector in a plug-in direction of the plug-in connector, comprising a sealing section adapted to hold a sealing element for sealing up between the plug element and the mating plug element, wherein the sealing section comprises at least one counter retention element adapted to engage with a retention element formed at the sealing element in order to secure the sealing element against movements in parallel to the plug-in direction.
  • the present invention relates to a sealing element for sealing up between a plug element and a mating plug element of an electrical plug-in connector, an axial direction of the sealing element running essentially in parallel to a plug-in direction for mating the plug element and the mating plug element.
  • the present invention relates to an electrical plug-in connector.
  • the plug-in connectors comprising the housings and the sealing elements are often used in hostile environments as they may be applied in vehicles for example. In these hostile environments, the plug-in connectors are exposed to vibrations, moisture, dirt, dust and possibly chemical aggressive substances. When aggressive, corroding or electrically conductive substances would get into a connection area between mating contact elements of a connector, they could cause interruptions of the power supply or false circuits.
  • the connectors have to be provided with sealings which prevent any harmful substances from entering the connector and affecting the contact elements arranged therein. It is desired to hermetically seal the connector.
  • An overall sealing should at least be liquid-tight and optimally gas-tight.
  • a sealed electrical connector according to the prior art is described in the US patent specification US 7,540, 775 B2 for example which shows a sealed electrical plug-in connector.
  • a plug seal of this connector is arranged between a header shroud and a receptacle housing.
  • a flange formed at the seal and radially extending therefrom is jammed between the bottom formed at the receptacle housing and a rim of the header shroud.
  • an object underlying the invention is to provide an electrical plug-in connector which is sealable and reliable, yet easy to use and to assemble.
  • the sealing element further comprises at least one retention element adapted to engage with a counter retention element formed at least at one of the plug element and/or the counter plug element according to the present invention in order to secure the sealing element against movements in the axial direction and/or plug-in direction.
  • the plug-in connector comprises at least one sealing element and a receptacle housing according to the present invention.
  • the sealing element may be properly retained in its mounted position at the plug element and/or the mating plug element. It may thereby not be deformed, folded or wrinkled while mating the plug element and the mating plug element. Further, the sealing element may not get pulled out of its mounted position so easily when un-mating the plug element and the mating plug element.
  • the plug element may be a first connector element and the mating plug element may be a second connector element of an electrical plug-in connector, wherein the first connector element in the second connector element may have complementary shapes in order to be brought into engagement with each other when mating. During mating and un-mating the sealing element may be accurately kept in place while bringing the plug element and the mating plug element into engagement with each other.
  • the at least one counter retention element is resiliently deflectable in a direction extending essentially perpendicularly to the plug-in direction.
  • the counter retention element may be formed as snap-in tongue at least partially extending in parallel to the plug-in direction.
  • the counter retention element may have spring characteristics in a direction extending essentially perpendicularly to the plug-in direction whereby the counter retention element may snap into the retention element and thereby may be easily brought into engagement with the retention element.
  • a cavity for at least partially receiving a header shroud of the plug element or the mating plug element may be formed between the counter retention element and a wall of the receptacle housing. This cavity may accommodate the header shroud in a fully mated state of the plug element and the mating plug element.
  • the sealing element and/or the counter retention element may thereby be immobilized between the header shroud and the wall of the receptacle housing, such that the sealing element and/or the counter retention element may not move in a radial direction or a direction running essentially perpendicularly to the plug-in direction.
  • the retention element and the counter retention element may be held in a retention position and/or mounted position, respectively.
  • the at least one retention element may at least partially extend in a radial direction of the sealing element, wherein the radial direction is extending essentially perpendicularly to the axial direction.
  • the retention element may be brought into engagement with the counter retention element in such a way that movements of the sealing elements in parallel to the axial direction and/or plug-in direction may be blocked and the sealing element securely immobilized.
  • the at least one retention element may be formed as a recess. Thereby, the counter retention element may protrude into the retention element for blocking and/or latching the sealing element in its mounted position.
  • the at least one retention element may be formed as a groove which at least partially extends along a circumference of the sealing element.
  • the counter retention element may interact with the retention element along the circumference of the sealing element in order to secure the sealing element along its circumference and prevent even a partial folding or wrinkling as well as partial displacement of the sealing element with respect to its mounted position.
  • the sealing element may comprise a sealing portion and a retention portion attached to the sealing portion and providing the at least one retention element.
  • the sealing function may be assigned to the sealing portion and the retention function may be assigned to the retention portion.
  • the sealing portion may be designed for optimal sealing characteristics and the retention portion may be designed for optimal retention characteristics.
  • the sealing portion and the latching portion may have an essentially planar side on a side of the sealing element lying opposite the retention element. On the planar side, the sealing portion and the latching portion may be aligned with respect to each other, at least in parallel to the axial direction. Any sealing protrusions such as lamellas on a sideline opposite to the planar side may provide a structured side of the sealing element. Hence, the sealing element may be brought into flush abutment with its planar side to the plug element and/or mating plug element which enhances sealing up the electrical connector while on the other side, the retention element may be easily accessed.
  • the retention element may provide an engagement surface in form of a bevel which is at least partially slanted with respect to the axial direction. Thereby, the counter retention element may easily be brought into engagement with the retention element in that the counter retention element may slip into the retention element along the bevelled engagement surface.
  • the sealing element may at least partially have a ring-like cross-section. Thereby, it may be elastically deformable in a radial direction. Thus, it may be elastically tensioned when wrapped around a plug portion for example in order to enhance sealing characteristics.
  • the sealing element may generally have a tubular shape. Hence, the sealing element may provide a tubular inner circumference as well as a tubular outer circumference which may be brought into flush abutment with the plug element and/or the mating plug element.
  • the plug-in connector comprises at least one plug element and a mating plug element, wherein a fully mated state of at least one plug element and the at least one mating plug element, the retention element and the counter retention element are blocked in a retention position. Thereby, accidentally disengaging the retention element and the counter element may be prevented.
  • the retention element and the counter retention element may be adapted for engagement with each other in the mounted position and/or locked or retained position of the sealing element.
  • the retention element and the counter retention element may overlap with the plug element and the mating plug element in a direction perpendicular to the plug-in direction. Thereby, for example in a radial direction of the plug-in connector, any displacement of the retention element and the counter retention element is omitted which helps in securely immobilizing the sealing element in its mounted position.
