Definitions

  • the invention is based on an electrical connector according to the preamble of claim 1.
  • Electrical plug connections are known in which the releasable coupling of a plug to a mating plug takes place without sealing elements and the contact elements which are connected to mating contact elements are mounted in a contact carrier with a narrow grid spacing. If the electrical plug connections are installed in a motor vehicle, such unprotected plug connections can lead to the penetration of moisture and vapors, which can affect the electrical conductivity of the plug connection as a result of corrosion processes.
  • accelerations act on the plug connections as a result of shaking movements, so that in the case of coupled plug connections between assigned contact elements, one
  • EfiSArZBlAI (RE6 £ L 26) Plug and contact parts of the mating connector relative movements can occur within the scope of the bearing clearances. This means that the contacting surfaces of the contact elements and the contact parts can rub through, and the contacts are then made via the less well contacting carrier material of these elements, as a result of which the contact reliability of the plug connection is no longer guaranteed.
  • electrical plug connections which have sealing elements compared to the plug connections described above.
  • the contact elements of the plug and the contact parts of the mating connector of the plug connection are then respectively stored in individual chambers of the contact carrier, the grid spacings of which are comparatively large, since the sealing elements, for example individual wire seals, are also present in the chambers.
  • the construction volume of the plug connection is comparatively large with the same number of poles, and in individual cases the construction volume of the plug connection turns out to be larger than that of the assigned control device. This can lead to handling difficulties in an undesirable manner, particularly when the plug connection is used in the engine compartment of a motor vehicle given the limited space available there.
  • the plug connection according to the invention with the characterizing features of claim 1 has the advantage that the aforementioned shortcomings are avoided and a reliable plug connection is realized.
  • the at least one sealing element which is non-positively fixed when the plug is coupled to the counterplug, realizes a plug connection which has a compact structure, which is sealed and which remains functionally reliable even with shaking accelerations.
  • FIG. 1 shows the plug of the plug connection, broken down into its main components, in a perspective view
  • FIGS. 2 to 4 show parts of the plug in sectional representations
  • FIGS. 5 and 6 show the mating plug in a radial or Axial section
  • FIGS. 7 and 8 the complete plug in various views and FIGS. 9 to 10, partially sectioned, the plug before contacting the mating plug
  • FIG. 11 shows a side view of the one with the mating plug contacted plug in the end position of the assembly corresponding to a closed position of the connector.
  • a plug 12 is shown in FIG. 1 as part of a plug connection.
  • This comprises as main components a connector housing 14 made of plastic, which is designed as a grip shell, two interlocking contact carriers 16 made of plastic, which can be inserted into the box-shaped connector housing 14, a sealing plate 18 either made of a rubber-elastic or one elastic gel-like material, which can be inserted into a space provided for this purpose in the connector housing 14 via the contact carrier 16 and can be axially compressed by means of a pressure plate 20, a frame-shaped sealing element 22, which rests on an abutment shoulder 24 and a circumferential line in the same direction, with recesses in some areas provided shoulder 25 (FIG. 2) of the connector housing 14, a locking lever 26 for closing and opening the connector, which is pivotably mounted on a holder 28 of the connector housing 14, contact elements 30 (FIG. 4) which

  • media for example, jet water
  • the electrical lines 36 are fastened to the connector housing 14 with a tensioning strap 44 (FIG. 7) when they exit.
  • the plug connection has, in addition to the plug 12 as its counterpart, a mating plug 46 which can be coupled to it via contact parts 45 (FIGS. 5, 6).
  • the mating connector 46 is part of a control device, not shown; alternatively, it can also be attached to a unit as a fixed connection.
  • the mating connector 46 has a circumferential collar-shaped receptacle 47 (FIG. 2) for the non-positive connection with the sealing element 22 of the connector 12.
  • the prepositioned connector 12 is pulled into the mating connector 46 by a pivoting movement of the locking lever 26 in the direction of an arrow 48 (FIG. 9).
  • the pivot connection of the locking lever 26 is converted into a linear movement of the connector 12 towards the mating connector 46 by the guidance of bolts 50 which are attached to it

  • the bolts 50 which each have a circumferential collar 54 at their free ends, are guided in a radially secured manner in the link 52 designed as a groove with a T-shaped cross-sectional area.
  • the locking lever 26 is assigned first, second and third latching elements 56, 58, 60 ( Figures 9, 11) securely locked.

  • the arrangement and design of the sealing plate 18 and the sealing element 22 results in a plug connection in the previously described deformation, which is compact and leakproof and has a high resistance to shaking.

  • the corresponding guide elements 62, 64 and 66, 68 enable precise guidance between the connector 12 and counter connector 46. They are designed so that they form a basic guide.

  • the contact carriers 16 have the same shape, as a result of which the large number of parts of the plug connection is reduced.

Abstract

L'invention vise à réaliser un connecteur électrique qui soit compact, étanche aux influences extérieures, notamment à l'humidité, et demeure fiable même lorsqu'il est soumis à des secousses. Ce connecteur comprend une plaque d'étanchéité (18) en matériau élastique, montée dans une section d'un boîtier de prise (14) et pouvant être comprimée par déformation sur des conducteurs (36) menant aux éléments de contact (30) d'une prise (12). Un élément d'étanchéité (22), sous forme de cadre placé comme garniture d'étanchéité radiale dans un épaulement d'appui (24) du boîtier de prise (14), est comprimé dans le sens axial et radial lors du raccordement de la prise (12) et de la contre-fiche (46), par ladite contre-fiche (46). Ce connecteur s'utilise de préférence dans des automobiles, pour des éléments montés sur le moteur, qui sont soumis à des secousses importantes en cours de fonctionnement.
