Definitions

  • the invention relates to a connector, such as a plug or a socket which is mated with a mating connector, according to the features of the preamble of claim 1.
  • a connector which comprises a contact carrier with openings, wherein the openings has one or more contact partners for the electrical connection of the connector.
  • the contact carrier and the cable outlet area is surrounded by a relatively soft plastic material, such as rubber.
  • This jacket of the connector in a round design extends over the outer surface of the contact carrier and the front side in the direction of the mating connector also slightly above the front side of the contact carrier. This is to prevent dirt particles or moisture from penetrating into the gap between the contact carrier and the jacket in the event of a connector not plugged together.
  • both elements contact carrier and jacket are produced separately from one another, it is extremely difficult to cover the complex-shaped jacket over the contact carrier. If both elements (contact carrier and jacket) are produced in one operation, in which, for example, the contact carrier is encapsulated with the material of the jacket, a complex shaping and sealing of the openings of the contact carrier is required so that no plastic injection-molding material can penetrate there.
  • the invention is therefore based on the object to provide a connector, such as a plug or a socket, with which the initially described disadvantages are avoided, in particular in the assembled state of connectors and mating connector reliable sealing effect is achieved, the sealing element required for this purpose can not be forgotten during assembly of the connector and in which it does not necessarily depend on a seal between the jacket and the contact carrier of the connector in the unplugged state.
  • a generic connector such as a plug or a socket, according to the invention is characterized in that the sealing element captive disposed on the shell and from a first position (after its manufacture) in its final position (before or during assembly of the connector) in its final position can be brought, in which it effects a sealing effect between the connector and the mating connector in the mated state.
  • the captive arrangement of the sealing element on the jacket has the advantage that the sealing element can not be forgotten in the mating of connectors and mating connectors, since it is important for the sealing effect between these two parts. Equally important is the sealing element in the assembled state of connector and mating connector for sealing the gap between the contact carrier and the jacket itself, so that neither in a gap between connector and mating connector (gap between the end faces) still in the gap between the contact carrier and the jacket of the connector or the mating connector soiling, moisture or water can penetrate.
  • the captive arrangement of the sealing element on the jacket also means that these two parts are produced in one piece, although after their production not the final position is reached each other, but after the manufacturing process, the sealing element occupies a first position with respect to the jacket.
  • the sealing element comes into its final position with respect to the jacket, this final position is seen in that the sealing elements, for example, plane-parallel and at least partially flat on the front side of the Contact carrier gets to the plant.
  • the sealing element it is also conceivable that already surrounds the end face of the shell in its final position. This means that the sealing element forms an integral part of the jacket, but only partially connected to this, to ensure that the sealing element can be brought from its first position to its final position without great effort and preferably without tools.
  • the sealing element is arranged via a connection to the jacket, wherein in a particular embodiment of the invention this Connection is designed as a film hinge.
  • a connection in particular the film hinge, can be easily produced in a plastic injection molding process, so that the sealing element can be sprayed on the jacket quickly and easily in a single manufacturing step.
  • the material of the shell and / or the compound and / or the sealing element is the same or different.
  • shell, joint and sealing element can be made into a one-piece part in a two-component or multi-component plastic injection molding process.
  • the sealing element in its final position non-positively and / or positively locking on the contact carrier and / or on the jacket can be fixed.
  • This connection can be configured, for example, as an adhesive connection, in which the sealing element is at least partially or completely adhered to the jacket (but not in the region of the connection, where it is already fixed thereto) and / or in the region of the end face of the contact carrier.
  • the front side of the shell and / or the front side of the contact carrier and / or the front side of the contact carrier facing surface of the sealing element may be provided with an adhesive or provided with an adhesive layer, which is then active or activated (eg, under heat, If the sealing element has assumed its final position with respect to the contact carrier If the jacket and sealing elements are made of rubber, for example, it is also conceivable to vulcanize the sealing element at the edge with the jacket (but not in the region of the already existing connection).
  • the sealing element is connected via a latching connection with the contact carrier.
  • a latching connection has the advantage that the corresponding latching means (such as detent holes, latching noses, recesses, latching hooks or the like) can be produced even with the production of the shell with the molded sealing element.
  • the locking connection has the advantage that it is very easy and quick to assemble and other materials (such as the required adhesive in an adhesive bond) are unnecessary.
  • a connector 1 is shown, which is an angular connector in angled construction.
  • the invention is not limited thereto, so that it is also applicable to connectors in a straight design and also in round design.
  • the connector 1 has a contact carrier 2 made of plastic, which has one or more openings 3, wherein the openings 3 not shown contact partners (such as socket elements or contact pins) record. Likewise, but need not, the contact carrier 2 for receiving an electronic circuit, display means or the like may be formed.
  • the contact carrier 2 is surrounded by a jacket 4, also made of plastic material.
  • the material of the jacket 4 consists of a relatively soft plastic material and is manufactured in an injection molding process in which the contact carrier 2 and a cable outlet region 5 is surrounded by the material of the jacket 4.
  • a sealing element 6 is integrally formed on the jacket 4 via a connection 7, it being shown in the figure that the sealing element 6 assumes a first position with respect to the jacket 4.
  • This first position of the sealing element 6 with respect to the contact carrier 2 is approximately at right angles, but may also differ from it.
  • the sealing element 6 is arranged on one side of the jacket 4 via a connection 7, which is formed in a particularly advantageous manner as a film hinge. If the connector 1 is a plug connector in a round design, the connection 7 is arcuate and the cross section of the sealing element 6 adapted to this design. Further points the sealing element 6 a recess 8 which is configured so that at least the openings 3 with the contact partners arranged there for a mating connector (not shown here) are accessible.
  • the sealing element 6 is arranged captively on the jacket 4 via the connection 7.
  • the outer dimensions of the sealing element 6 correspond to the outer dimensions of the shell 4, so that the outer end faces of the sealing element 6 are flush with the outer surface of the shell 4, after the sealing element 6 has been brought into its final position. This is done by simply folding the sealing element 6 in the direction of the end face of the contact carrier 2, where it is non-positively and / or positively lockable.
  • the sealing element 6 is fixed plane-parallel to the end face of the contact carrier 2 and the peripheral end face of the shell 4 via a latching connection.
  • the sealing element 6 has one or more latching lugs 9, which engage in the contact carrier 2 after folding of the sealing element 6 in corresponding locking holes 10.
  • the mushroom-shaped latching lugs 9 may also be designed as latching hooks or the like. It is also conceivable that the detents on the contact carrier 2 and the detent holes (or corresponding recesses) are arranged on the sealing element 6.
  • the sealing member 6 After the sealing member 6 has been brought from its position shown in the final position, not shown (folded down), close the outer circumferential end faces of the sealing element 6 flush with the outer surface of the shell 4 flush or stand beyond or stand back. After the sealing element 6 has been brought into its final position, the connector 1 is fully assembled and can be plugged together with its mating connector.
  • the connector 1 and its mating connector are advantageously designed so that a pressure in the axial direction of insertion is generated on the sealing element 6, so that this comes in mated condition under pressure between the respective end faces of the contact carrier to the plant and thereby, as it also from a set relatively soft plastic material, deformed in a manner that in the assembled state, a sealing effect between the connector and mating connector, but also a sealing effect between the jacket 4 and contact carrier 2 (the connector 1, but also in its mating connector) is achieved.
