Definitions

  • the present invention relates to a connecting element, in particular a plug or a socket, for a connector and a connector with two such fasteners.
  • connectors are usually used with two connecting elements, namely a plug and a corresponding socket.
  • a connector e.g. two electrical cables or lines, such as a supply line connected to a supply network and a connected to an electrical load or generator connecting cable are interconnected.
  • the connectors used allow it to selectively connect electrical lines with each other and to solve each other again.
  • a connector of this type which is intended for outdoor use of solar systems, is from the published patent application DE 10 2008 045 801 A1 known.
  • the connector is formed by a socket and a connector connected thereto, each having a contact carrier, in which a contact pin or a contact socket is held.
  • the contact carrier takes the end of a cable seal with a strain relief claw.
  • the strain relief claw acts together with a pressure screw to decouple tensile and compressive forces acting on a cable from the contact pin.
  • Contact pins or contact sockets usually have a detent spring, which at a central part of the contact pin or the contact socket is attached.
  • detent springs are elaborately designed and therefore expensive to manufacture.
  • the middle part of the contact pin is extended, whereby additional material is needed, which causes considerable costs in the usual high quantities.
  • Photovoltaic systems usually include a plurality of solar panels, by means of which electrical energy is generated. These solar panels have outgoing cable sets, which eventually lead the generated electrical energy through various technical facilities to a grid transfer point. For reasons of ease of assembly, it is now common to equip the solar panels, as well as the associated lines, which dissipate the electrical energy with a connector. With regard to operational safety, high demands are placed on the reliability of these connectors. For example, the connectors have to withstand all the weather and environmental conditions that occur on site for a very long period of time, eg 20-30 years. Here are high electrical and mechanical requirements to meet. So should the lowest possible electrical contact resistance at the connector occur over the entire life, so that the transfer of the total power of the solar system is not adversely affected. If an increased contact resistance occurs, an operational failure, possibly a fire or further damage may occur in individual cases. In addition to an increased contact resistance and leakage currents are to be avoided, which can form in particular under the influence of moisture and impurities.
