Definitions

  • the present invention relates to an electrical contact socket for a electrical connector according to the preamble of claim 1.
  • Such electrical connectors are provided via a Contact socket and a pin between a first electric wire and another electrical line or between an electrical line and an electrical unit a re-releasable electrical connection manufacture.
  • Possible applications are u. a. around Automotive electronics.
  • the connectors must be due to the extreme harsh environmental conditions, in particular with regard to vibration resistance and Corrosion resistance, but also in terms of temperature resistance and Current resistance meets high requirements.
  • the connections must over it Be often solved and can be reliably closed again. In addition, when plugging and opening as little forces as possible overcome.
  • European Patent EP 0 711 009 B1 describes one according to the Preamble of the main claim trained electrical contact socket.
  • the Contact socket consists essentially of a rectangular in cross-section trained body with a detent spring tongue for locking the Contact socket in a chamber of a housing.
  • the main body has an im Essentially rectangular in cross-section quiver-like design Has contact area, for holding a contact spring receiving is provided.
  • the contact spring consists of a contact plate, which is U-shaped bent around the transverse to its longitudinal extension middle zone is, so that two substantially at a distance parallel to each other Contact arms are formed whose free ends for fixing the contact spring on Body both positive and cohesive (welds) with communicate with the opening area of the contact area.
  • This type of contact socket has significant disadvantages: it is only one single contact point between the main body and the contact spring, namely the in the opening area of the contact area, provided, whereby a high Contact resistance between body and contact spring results.
