Definitions

  • the invention relates to a connector, comprising a connector housing having at least one recess for receiving a contact partner having contact area, wherein circumferentially on a pointing to a mating connector end face of the connector housing a seal is arranged, according to the features of the preamble of claim 1.
  • plug connections which consist of plugs and mating plug connectors (also called a socket, socket or coupler) that a seal is arranged between these two parts of the mated plug connection which prevents the penetration of moisture, water, dirt particles or the like in the direction of prevents each other corresponding contact partners.
  • This is essential because the ingress of such contaminants can lead to malfunction, failure or the like of those devices, actuators, sensors or the like, which are connected to each other via the mated connector. Therefore, it is particularly important to arrange an effective seal between the two mating elements of the connector, namely the connector and its corresponding mating connector.
  • the invention is therefore based on the object to improve the seal between a connector (also called as plug) and a mating connector (eg, coupler, can or book called) to effectively prevent the ingress of water, moisture, contaminants and the like and to increase the fatigue life of the seal.
  • a connector also called as plug
  • a mating connector eg, coupler, can or book called
  • the seal which is arranged on the front side of the connector (additionally or alternatively also on the front side of the mating connector), has a curved cross-section such that the narrow end region is fastened to the front side and the wide end region is free in the direction the mating connector protrudes.
  • This particular cross-section of the seal over the previously known rectangular cross-sections has the particular advantage that here the Anpress Wald the seal on the part of the connector by a bending stress of the seal in the region of the front side of the adjacent mating connector (or vice versa) and not by a squeezing.
  • this curved cross-section for example sickle-shaped, hollow-fluted or the like, a much better system and thus a much better seal against previously known seals that have been squeezed when mating connector and mating connector, achieved.
  • the narrow end portion is glued to the front side.
  • the plug connector housing In addition or as an alternative to the gluing of the seal on the front side, it is conceivable for the plug connector housing to have a groove for receiving the seal and for the narrow end area to be pressed into the groove on the end face.
  • the groove and / or the seal can have a respective undercut corresponding to one another.
  • the seal in the groove can also be glued. It is important that the wide end portion of the seal projects freely in the direction of the mating connector and the Anpress Wald, ie the seal, is achieved by the bending stress of this projecting region on the front side of the mating connector.
  • the connector housing and the seal form a one-piece component.
  • Such a connector housing with molded seal made of the same or different material can be produced in a plastic injection molding process, in particular in a two-component or multi-component injection molding process.
  • Particularly advantageous is the application of the seal according to the invention in a connector, as it is known from DE 10 2006 033 139.7.
  • the single FIGURE shows, as far as shown in detail, with the reference numeral 1 a connector having an external connector housing 2, in particular made of plastic.
  • the connector housing 2 has, for example, a molded-on cable outlet 3, via which a cable 4 is led out of the connector housing 2.
  • an unspecified contact carrier is arranged, which has an end face 5.
  • this contact carrier there is present in single or multiple numbers a contact region 6, which has a recess 7, in each of which an unillustrated contact partner (for example, pin or socket or the like) is arranged.
  • the individual electrical conductors of the cable 4 are arranged within the connector housing 2, for example, these are soldered, crimped or the like.
  • the connector 1 For connection to a mating connector, not shown, may, but need not, the connector 1 have a central screw 8.
  • a Seal 9 is arranged in the direction of the mating connector, which has such a curved cross-section that the narrow End portion is fixed to the front side 5 and the wide end portion projects freely in the direction of the mating connector. This is to be understood by fixing the narrow end portion that this can be attached either only to the connector housing 2 or only in the region of the end face 5 of the inner contact carrier or therebetween, or on both components.
  • the connector housing 2 protrudes slightly beyond the end face 5 and this projecting edge region of the connector housing 2 is glued to the narrow end region of the seal 9.
  • the contact carrier to which the narrow end region of the seal 9 can be glued.
  • only the contact carrier or only the end portion of the connector housing 2 has a circumferential groove for receiving the narrow end portion of the seal 9.
  • the adjacent areas of connector housing 2 and inner contact carrier together form the groove, optionally with an undercut, for receiving the narrow end portion of the seal 9.
  • the seal 9 is formed in one piece and is arranged on the connector housing 2 or on the contact carrier, that the one or more contact regions 6 are arranged inside.
  • the cross section of the seal 9 which has a curved shape, such as a sickle or chamfer shape.
  • This ensures that the seal 9 comes by a bending stress and not by a squeezing on the mating connector to the plant.
  • This makes it possible to increase the sealing effect, just as the durability of the seal 9, since due to this shape of the seal 9 is not applied in a disadvantageous manner squeezing, but the seal due to the bending stress on the mating connector comes to rest, which is guaranteed in that after the disassembly of the plug connection, the seal 9 can assume its original shape again.
  • the seal 9 consists of an elastically deformable material, such as a rubber, a polymer or the like.
  • the seal 9 consists of an elastically deformable material, such as a rubber, a polymer or the like.
  • the seal 9 consists of an elastically deformable material, such as a rubber, a polymer or the like.

Abstract

L'invention concerne un connecteur à fiches (1), présentant un boîtier de connecteur (2) avec au moins une région de contact (6) pourvue d'un évidement (7) pour recevoir un partenaire de contact. Un joint d'étanchéité (9) est disposé tout autour sur une face frontale (5) du boîtier de connecteur (2) qui est tournée vers un connecteur homologue. Selon l'invention, le joint d'étanchéité (9) présente une section cintrée de telle sorte que la région terminale étroite est fixée à la face frontale (5) tandis que la région terminale large fait librement saillie.
