Definitions

  • the invention relates to an electrical plug connection, consisting of a plug part and a mating connector part, which can be plugged together and produce a plurality of electrical connections, wherein at least the plug part or the mating connector part carries on its body a screwed with the mating connector part or the plug part union nut, which is the connector protects against unintentional disconnection.
  • connection technology is designed so that it securely connects the contact elements electrically to each other and protects with the connector coming into contact persons from dangerous voltages.
  • connectors which consist of a multi-pin connector part with contact sockets and a multi-pole mating connector part with contact pins, which are designed so that they largely protect the electrical contact elements against mechanical and atmospheric influences.
  • a disadvantage of these known connectors is the time required for screwing or unscrewing the nut during manufacture or when disconnecting the connector.
  • Another disadvantage is that in a arranged between the faces of the male and mating connector sealing ring of the sealing ring is not always crushed so that it reliably seals the annular gap between the plug part and the mating connector part against the ingress of moisture. This is particularly the case when customary connector parts and mating connector parts of different manufacturers are used in pairs, since this often results in an easy game. This also causes a loosening of the nut by shaking movements.
  • the invention is based on the object to improve a connector of the type mentioned in such a way that the disadvantages described above are reliably avoided; in particular, on the one hand, a release of the nut is reliably prevented by shaking and On the other hand, a quick installation with as few rotational movements can be done.
  • the connector according to the invention has a union nut with two internal threads, wherein one of the two internal threads is provided for screwing with the plug part and the other internal thread for screwing with the mating connector part.
  • the internal threads of the union nut are arranged opposite each other and extend to the end faces of the union nut. They are designed in opposite directions, and have an identical thread pitch.
  • At least one of the two internal threads of the union nut is segmented.
  • the segmented internal thread of the union nut has at least one thread-free region running in the direction of insertion, which is almost completely inserted into the complementary formed external thread of the associated male or mating connector part and the tightening of the screw on a rotation of the nut reduced by at most the thread-free area.
  • Another advantage is the plug part and the mating connector part plugged together and the electrical connection can be made without screwing the connector. This can be helpful, for example, when commissioning and troubleshooting electrical devices and systems, if in the event of a fault, the plug connection must be quickly released and a faulty part replaced.
  • an inventive plug part or mating connector part can be combined with the cap nut according to the invention with standard connectors of the same size and the same connection type, which ensures the connection to commercially available connectors.
  • the segmented internal thread at the end faces of the nut facing side, on a first thread with a deviating from the threads of the external thread of the male or mating connector part cross-sectional profile.
  • the first thread of the internal thread can not be brought into engagement with the thread of the external thread of the mating connector or plug part, which ensures that the connector part can only be screwed to the mating connector part when a contact carrier of the connector part is completely inserted into a threaded sleeve of the mating connector part is.
  • the union nut is rotatably and slidably mounted on the body of the supporting plug or mating connector part.
  • the nut is on the one hand secured against loss, on the other hand is a Plugging into a thread-free region of the thread of the supporting connector part possible, which has an advantageous effect on the assembly time in the production of the connector.
  • To lock the nut must be rotated only by about a quarter to half turn, so that the threads of the thread engage in each other and make a screw.
  • a development of the invention provides that the plug part and the mating plug part have at least partially axially aligned toothing profiles on their end faces.
  • the tooth profiles are designed to be complementary and engage in screwing the connector into each other, they align the male part and the mating connector in the circumferential direction of the connector play each other.
  • the profiles can be formed on corresponding end faces or lateral surfaces of the plug connection parts and, for example, have a sawtooth, trapezoidal or sinusoidal cross-section.
  • the toothed profiles connect the plug part and the mating plug part form-fitting and force-locking with each other, whereby inadvertent rotation of the plug and the mating connector each other when tightening the nut is prevented and the electrical contact elements are protected from damage.
  • the electrical contact elements in the male and the mating connector part are protected by seals from moisture.
  • the plug nut or mating connector part carrying the union nut has a first sealing ring on the end face of the plug or mating connector part carrying the union nut and a second sealing ring in the region of the end faces of the union nut.
  • the first sealing ring is radial when tightening the nut of the union nut squeezed and pressed against the body of the plug or the mating connector, he seals a first annular gap between the mating connector or plug part and the union nut of the connector in the assembled and bolted state of the connector.
  • the second sealing ring is radially pressed when plugging or screwing the nut on the male or mating connector part; it seals a second annular gap between the plug or mating connector part and the union nut.
