Definitions

  • the invention relates to a connector part with a housing and at least two contacts and an insulation and sealing element.
  • the connector part may be a socket or a plug part, which together form a plug connector.
  • An important parameter of such a connector is the dielectric strength, so the ability of the connector to prevent flashovers between the contacts.
  • the dielectric strength is determined on the one hand by the length of the air and creepage distances between the contacts. The larger the creepage distances and creepage distances, the higher the rollover resistance.
  • the dielectric strength is further influenced by any impurities inside the connector. Such impurities can arise, for example, when the connector is exposed to vibrations. These vibrations can lead to relative displacements between the socket and the plug part and thus between the contact sockets and the contact pins. This can cause abrasion, which can settle on the housing bottom between the contacts and reduces the dielectric strength.
  • a waterproof connector which uses a sealing insert, which is arranged in the plug part.
  • the sealing insert has around each contact of the plug part around an opening into which a housing part of the socket part can be inserted.
  • the object of the invention is thus to improve a connector part to the effect that a higher dielectric strength is achieved.
  • a plug part is inventively provided with a housing and at least two contacts, wherein an insulating and sealing element is arranged at the bottom of the housing, which with through openings for the contacts are provided and consist of an elastic, electrically insulating material with high dielectric strength, wherein the insulating and sealing element has at least one rib on at least one of its sides, which lies between two passage openings, and wherein the housing is provided with at least one recess, in which the rib engages.
  • the insulating and sealing element acts in two ways: Firstly, it is in nested connector parts on the respective housing bottom, so that the air gap between adjacent contacts is interrupted. This increases the dielectric strength.
  • the insulating and sealing member seals on the housing bottom around the contacts around, so that any abrasion that arises in this area is trapped in the Kunststoffkammem and can not be reflected on the housing bottom between adjacent contacts.
  • This additionally increases the dielectric strength.
  • dielectric strength refers exclusively to the resistance to electrical breakdown and not to mechanical strength.
  • the rib together with the recess acts like a labyrinth seal, which extends the air and creepage distances between adjacent contacts. This also increases the dielectric strength.
  • the connector part is a plug
  • the contacts are contact pins and that the diameter of the passage openings is smaller than the diameter of the contact pins, so that the insulating and sealing element frictionally on the contact pins and thus in Housing is held.
  • the insulating and sealing element thus remains even after loosening the plug connection in the plug, without requiring separate holding elements or the like are required.
  • an insulating and sealing element is provided with a plate-shaped body having at least two through openings for contacts of a connector part and is provided on at least one of its sides with at least one rib which is disposed between the passage openings, said the body consists of an elastic, electrically insulating material with high dielectric strength.
  • a connector part 5 which is designed here as a plug.
  • the plug has a housing 10, which consists of an electrically insulating material and in which six contact pins 12 are arranged.
  • the housing 10 has a housing bottom 14, through which the contact pins 12 extend.
  • a total of three recesses 16 are arranged, of which only two can be seen in Figure 1 and whose course will be explained later.
  • an insulating and sealing element 20 (see in particular Figure 3) is arranged, which consists of an elastic, electrical insulating material with high dielectric strength and has a plate-shaped body 22.
  • the body 22 six through openings 24 are formed for the contact pins 12, the position of the arrangement of the contact pins 12 in the housing 10 corresponds.
  • On its opposite outer sides of the body 22 is provided with three ribs 26 which are arranged so that they each enclose a passage opening from the edge of the body 22 partially.
  • the ribs could also be arranged differently; it is only important that there is always a rib between two adjacent passages 24. For example, if the plug had a center contact, the associated passage opening 24 would be completely surrounded by a closed rib.
  • the insulating and damping element 20 is arranged on the housing bottom 14, that the ribs 26 engage in the recesses 16 in the housing bottom.
  • the recesses 16 have the same course as the ribs 26; so there are two recesses provided, each enclosing a lying in the corner pin, and a recess which encloses a centrally disposed on the opposite side pin.
  • the contact pins extend through the passage openings 24 of the insulating and sealing element 20, wherein these are dimensioned so that a press fit with the contact pins 12 is achieved. This ensures that the insulation and sealing member 20 is held captive on the housing bottom 14 in the plug 5 without further action.
  • a complementary connector part 30 is placed in the connector part 5, which is designed here as a socket.
  • This has a housing 32, in which contact sockets 34 are arranged.
  • the housing bottom of the housing 32 of the socket is provided in the same manner as the housing bottom 14 of the plug with recesses 36, in which engage the ribs 26 of the insulating and sealing element 20.
  • the distance between the opposite housing bases is dimensioned in nested connector parts so that the insulation and Seal member 20 is slightly compressed between the housing bases, so it rests tightly against them. In this way, the individual contact chambers are sealed from each other by the insulating and sealing element, so that any abrasion that arises in a contact chamber is trapped in this contact chamber.
  • the recesses 16, 36 together with the ribs 26 increase the air and creepage distances between the adjacent contact chambers, so that the dielectric strength is increased.
  • the insulating and sealing element 20 could also be arranged on the socket. Since it can not be held there by the contact pins, other fastening means would have to be provided.
