Definitions

  • the invention relates to an elastic seal for use on electrical connectors according to the preamble of claim 1 and a connector according to the preamble of claim 3.
  • the invention has for its object to provide an elastic seal for use on electrical connectors, which usually consist of a contact carrier, a housing and a cable to be connected to the connector, on the one hand enclosing the cable sealing and on the other hand has passages for parts of the connector , Furthermore, a connector is to be specified, which includes this seal.
  • the seal is integrally formed and has a centrally disposed bore for receiving the cable and adjacent to the bore has two axially parallel to the bore parallel displaced passages for receiving arms of the housing, wherein the passages are arranged opposite with respect to the bore on the one hand, the cable is sealingly enclosed and on the other hand, it has passages for parts of the connector.
  • circumferential inwardly facing ribs are arranged on the inner wall of the bore. These circumferential ribs are used to compensate for diameter variations of the cable or its outer sheath or shell.
  • the stated object is achieved in that the seal is arranged on the one hand frontally on the outer circumference between the contact carrier and the housing and on the other hand, the cable is guided sealed by the bore in the seal. If a mating housing is pushed onto the connector, the seal prevents ingress of moisture along the housing wall.
  • the housing has in a preferred embodiment, a housing bore for insertion of the cable into the connector and the housing are preferably arranged in the direction of the contact carrier cantilevers, which are inserted into the contact carrier and serve to attach the housing to the contact carrier.
  • the arms protrude through the passages in the seal.
  • the arms are attached in accordance with the invention configuration with the contact carrier via a latching connection.
  • the boom below the seal on a reduction in size, in which the seal is used.
  • An alternative connector is characterized in that the contact carrier consists of a lower part with the contact chambers for the electrical contacts and a lid which is fixed to the lower part latching.
  • the lid is connected to the lower part via one or more film hinges.
  • this alternative connector has cantilevers, which are arranged in one embodiment on the contact carrier in the direction of the housing. These booms have inwardly directed saw teeth which press on the cable, in particular its outer jacket.
  • the housing is preferably only one end part which is pushed onto the arms and engages them.
  • the seal is also pushed onto the arms and is located on the outer circumference between the lid in the closed state and the housing or end part.
  • the housing presses the boom together while also the seal between the contact carrier and the housing.
  • the cable is, as in the first embodiment, passed through the bore in the seal.
  • the invention thus describes a one-piece, against cable, plug housing and acting against plug seal.
  • the invention describes a connector designed as a plug or socket (also called coupler or box).
  • this connector is designed for the connection of electric motors to control units or power supplies, since in this case flow high currents and is to ensure a seal against moisture from the outside.
  • FIGS. 1a to 1f A first embodiment of the invention is shown in FIGS. 1a to 1f.
  • Figure 1f shows a seal 1, which has a central bore 6. Through this hole 6, a cable 5 (see Figure 1 c) out. So that moisture does not enter the interior of the connector 2 (see FIG. 1 a) along the cable 5, the gasket or the bore 6 completely surrounds the cable 5. On the inside of the bore 6 inwardly projecting circumferential elastic ribs 9 are arranged. These ribs 9 equal diameter variations of the cable 5.
  • Duchlässe 7 Laterally adjacent to the bore 6 two Duchlässe 7 are arranged, which are displaced parallel to the outside in relation to the bore 6. The function of these passages 7 will be described below.
  • Figure 1a shows a connector 2 with inserted seal 1 from the outside. Not shown is a counter housing in which the connector 2 is inserted or inserted.
  • the connector 2 consists of a housing 4 and a contact carrier 3, which are connected to each other via the seal 1.
  • FIG. 1 b shows the housing 4 with the gasket 1 and the cable 5 inserted.
  • FIGS. 1 d, 1 e show the housing 4 without gasket 1 and cable 5.
  • the housing 4 has a centrally introduced housing bore 10, through which the cable 5 is guided into the interior of the connector 2. From the housing 4 in the direction of the contact carrier 3, the housing 4 has four arms 8, which protrude into the contact carrier 3 and engage on this via a latching connection. The seal 1 is pushed onto the housing 4 in such a way that the arms 8 project through the passages 7 in the seal 1. To fix the seal 1 8 circumferential reductions 11 are placed on the arms, in which the seal 1 is embedded.
  • a gasket 1 is prepared and pushed onto a prepared end of a cable 5 (exposing the individual conductors of the cable 5, stripping the conductor ends so that the electrical conductors can be exposed and provided with contact partners).
  • a contact carrier 3 and a housing 4 of the connector 2 is prepared, in particular both together in one-piece form or separately from each other and made pluggable in a plastic injection molding process.
  • the contact carrier 3 has frontally recesses (contact chambers 18) in which the prepared ends of the individual conductors of the cable 5 with or without Contact partners are used. Before sliding the seal 1 on the cable end, the housing 4 is pushed onto the cable 5 and causes in the final assembled state a strain relief.
  • the seal 1 is pushed over the housing 4 at the front and then the contact carrier 3 firmly, in particular latching connected to the housing 4.
  • the seal 1 is slightly compressed, so that a seal is achieved on the one hand between the housing 4 and the contact carrier 3 and on the other hand between the seal 1 and the outer jacket of the cable 5 for the purpose of producing a longitudinal water-tightness.
  • the housing 4 is formed so that the seal 1 can still be mounted when the housing 4 has already been pushed onto the prepared end of the cable 5.
  • the connection between the contact carrier 3 and the housing 4 takes place in an advantageous manner by means of a latching connection, although other connections (such as gluing, with a circumferential tongue and groove and the like) are also conceivable.
  • the connector 2 here also has a contact carrier 3 and a housing 4.
  • the contact carrier 3 consists of a lower part 12 and a lid 14.
  • the cover 14 is here connected to the lower part 12 via two film hinges 15, which emanate from the end face 18.
  • contact chambers 13 are formed, in which the conductor ends of the cable 5 open.
  • two arms 16 extend in the longitudinal direction, each having saw teeth 17 on its inner side. Between these saw teeth 17, the cable 5 is guided in the contact carrier 3.
  • the seal 1 is mounted on the boom 16, wherein the boom 16 through the passages 7 in the seal 1 (see Figure 1f) are performed.
  • the cable 5 is guided through the bore 6 in the seal 1.
  • the housing 4 is pushed as a final part on the boom 16 and presses the seal 1 slightly together.
  • the stretch connector 2 differs from the connector of the first embodiment in that here the contact carrier 3 consists of two parts, wherein the one part (lower part 12) is provided with the contact chambers 13 for the contacts, while the other part (upper part) as a lid 14th is trained.
  • This cover 14 is attached to the lower part 12 via, for example, a film hinge or a plurality of film hinges 15 and is latchingly fixed thereto after the end of the cable 5 with its individual conductors and the contact partners arranged thereon has been fixed to the lower part 12.
  • the prepared end of the cable 5 was provided with a seal 1, which is over two arms 16, which extend from the base 12, is pushed over. These two arms 16 have inwardly directed saw teeth 17 which press on the cable 5, in particular its outer shell, and dig there for the purpose of strain relief when the cable side a final part (housing 4) has been pushed onto the contact carrier 3 with seal 1.
  • the final part (housing 4) latches on the latching hooks 19, which protrude outwards from the two ends of the extension arms 16, in such a way that after the latching there, the termination part (housing 4) compresses the two extension arms 16 and at the same time the seal 1 is compressed between the housing 4 of the connector 2.
  • a connector according to the present invention is available, which requires few parts, is easy to manufacture and assemble and, moreover, in harsh environmental conditions, especially in vibration, temperature fluctuations and above all moisture, water spray and the like is to use.
