Definitions

  • the invention relates to a plug-in connection, comprising a mounting socket and a connector plugged together, according to the features of the preamble of claim 1.
  • a plug connection is required, which may not have a form-fitting housing latching.
  • the background of this requirement is a precautionary avoidance of damage to the charging plug if the end user withdraws the plug without actuating the lock. Nevertheless, the customer should be given a haptic feedback for the proper mating process. Consequently, a kind of frictional locking is needed.
  • the challenge lies in the high insertion frequency of at least 1, 000 mating cycles and the associated problem of consistently noticeable locking. If, for example, small knobs or a circumferential rib are attached to the plug, which engage in an undercut in the mounting socket, it is assumed that this frictional connection initially very strong or hard, but hardly felt or soft over the life.
  • the invention is therefore based on the object to provide a connector that can be used according to the requirements outlined above.
  • a radial seal located on the connector is formed or arranged such that it dips into a circumferential undercut in the mounting socket.
  • the radial seal is advantageously used on the one hand to seal off the plug connector relative to the panel socket, when these two elements have been plugged together to form the plug connection.
  • the required haptic feedback in the process of mating is realized in that the surface of the radial seal, ie, that portion of the radial seal which projects circumferentially from the connector, dips into the corresponding circumferential undercut in the mounting socket.
  • an outwardly projecting radial seal is present for the constructive realization, whereby also in the panel socket, which likewise has a housing with a receiving space for at least a part of the plug connector this receiving space of the circumferential undercut is provided.
  • the protruding region of the radial seal corresponds correspondingly with the circumferential undercut, for example, a circumferential groove in the housing of the mounting socket.
  • the two housings each of the connector and the socket are matched accordingly, so that the connector can be inserted into the mounting socket, in this insertion the contact partners of these two elements are brought together and at the same time realized by means of the radial seal not only a seal against L josswasserein impart but also the haptic feedback is given to the user.
  • the radial seal is formed as an inserted into a circumferential recess of the connector O-ring.
  • the housing of the connector has for this purpose a corresponding circumferential recess, for example, a circumferential groove, in which the O-ring can be used as a separate component after the production of the connector.
  • this O-ring is chosen so that on the one hand reliable sealing of the connector against the panel jack is ensured in the assembled state and on the other hand, the haptic feedback after a variety of mating operations, often Several 100, if not several, 1000 plug-in operations (mating cycles) are retained.
  • the radial seal does not have a round cross section, but may also have different cross sections (as shown for example in the figures).
  • the radial seal is permanently connected to the connector.
  • the realization of such a permanent connection takes place, for example, in that the plug connector and the radial seal are produced in a per se known 2-component plastic injection molding process.
  • the housing of the connector is made of a hard plastic material, whereas the radial seal is made of a contrast softer plastic material.
  • the preparation of such a connector with an inextricably attached to it, ie arranged on its housing radial seal has the advantage that not two separate parts must be made and handled and assembled. As a result, the manufacturing process of such a connector is significantly simplified.
  • the mounting socket has an inwardly directed circumferential and cooperating with a survey of the radial seal groove.
  • Such an inwardly directed circumferential and cooperating with the collection of the radial seal groove can be introduced with the production of the housing of the mounting socket in this.
  • the cross section of this circumferential groove corresponds to the projecting from the surface of the housing of the connector elevation of the radial seal, so that the cross section of this protruding elevation can be accurately matched to the cross section of the circumferential groove to both the seal between the socket and connector and the haptic feedback to optimize in the mating process.
  • the mounting socket and the connector are designed to be plugged together without a positive locking housing.
  • the elimination of a positive connection between the housing of the mounting socket and the housing of the connector has the advantage that means that would cause such a form-fitting Genzouseverrastung can be omitted.
  • the design of the two elements of the connector simplified substantially.
  • the haptic feedback is given to the user when plugging the socket and connectors through the radial seal of the connector, with their collection in the corresponding geometry, in particular the circumferential groove in the housing Panel socket engages.
  • the radial seal combines two functions, namely the seal against longitudinal water and the haptic feedback for the user.
  • a connector 1 is shown.
  • the connector 1 comprises a mounting socket 2 and a connector 3, which can be detachably mated to the connector 1.
  • the connector 1 is shown in the assembled state, in which the connector 3 dips into a correspondingly shaped receiving space of the mounting socket 2.
  • contact partners which are arranged within the housings, which are also not shown in detail, the female connector 2 and the connector 3.
  • the connector 3 has a radial seal 4.
  • the radial seal 4 is arranged once circumferentially around the housing of the connector 3. It causes, on the one hand, that no longitudinal water can flow from the direction of the connector 3 in the direction of the panel socket 2 (or possibly also vice versa). The same applies to moisture, contamination by material particles or the like.
  • the radial seal 4 causes the haptic feedback to be given to the user during the insertion process, ie when the connector 3 is moved into the receiving space of the housing of the mounting socket 2.
  • a bevel (Beveling) arranged over which the radial seal 4 can slide in the insertion process.
  • the connector 3 shows an exemplary structural design of the mounting socket 2, the connector 3 and the radial seal 4 is shown.
  • the connector 3 has a recess into which the radial seal 4 is either used as a separate component or in the manufacture of the housing of the connector 3, the material which forms the radial seal 4 has been injected.
  • the radial seal 4 has a survey 5, with which the radial seal 4 projects beyond the surface of the housing of the connector 3.
  • the housing of the mounting socket 2 has an inwardly facing recess, in particular a circumferential groove 6, on.
  • the geometry of the survey 5 of the radial seal 4 and the circumferential groove 6 are coordinated so that, as already mentioned, the longitudinal water seal realized and the haptic feedback on a variety of plug-in operations (mating cycles) is given.
  • FIG. 3 shows by way of example an application of the connector 1 according to the invention.
  • the mounting socket 2 is arranged in a corresponding recess of a base plate 7 and fixed there.
  • the attachment is done for example by a screw, here four screw 8, in the base plate 7.
  • Other types of attachment such as locking, bonding or the like, are of course also conceivable.
  • the base plate 7 is for example part of a body of an electric vehicle, in which the mounting socket 2 is arranged and accessible from the outside, to accomplish a charging of an energy storage of the electric vehicle, when the connector 3 has been inserted into the mounting socket 2. This is for a such charging of an energy storage of the electric vehicle, the mounting socket 2 and the connector 3 matched to each other in particular to realize the required charging currents.
  • the connector 3 is disposed at the end of a correspondingly sized cable 9, wherein at the entrance of the cable 9 in the housing of the connector 3 for durability a kink protection 10 is provided.
  • the cable 9 is connected to a corresponding charging device (not shown), as well as the socket 2 has an electrical connection to the energy storage of the electric vehicle or a corresponding charging control device.
  • the connector according to the invention thus generally a sealing connection when plugged together of connectors in the mounting socket with simultaneous haptic feedback for the user to be realized.
  • the invention provides in other words, to use the already needed housing seal.
  • the on the plug (optionally on a cap) located radial seal is formed or arranged so that it dips in a circumferential undercut in the mounting socket. This gives the user a noticeable feedback on the completed plug-in process.
  • About the soft seal is in turn ensured that the haptics of the mating process remains unchanged as possible over life, as the seal no signs of wear in the form of Abschabitch or the like can be expected.
