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 plug pin between a first electrical line and another electrical line or between an electrical line and an electrical unit a releasable electrical connection manufacture.
  • Possible areas of application are a. in the field of Automotive electronics.
  • the connectors have to be extremely harsh environmental conditions, particularly with regard to vibration resistance and Corrosion resistance, but also in terms of temperature resistance and Current resistance meets high requirements.
  • the connections have to go over it can often be solved and reliably closed again.
  • the lowest possible forces should be applied when inserting and opening to be overcome.
  • the 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 cross section trained base body with a latch spring tongue for locking the Contact socket in a chamber of a housing.
  • the base body has an im Essentially rectangular-shaped quiver-like in cross section Has contact area, for holding a contact spring is provided.
  • the contact spring consists of a contact plate, which is U-shaped bent around the central zone running transversely to its longitudinal extent is, so that two substantially parallel spaced Contact arms are formed, the free ends for fixing the contact spring on Base body with both positive and material (weld points) are connected to the opening area of the contact area.
  • This type of contact socket has major disadvantages: it is only one only contact point between the base body and the contact spring, namely the provided in the opening area of the contact area, whereby a high Contact resistance between base body and contact spring results.
  • the required welding points complicate and increase the cost of assembly.
  • the object of the present invention is therefore to provide a contact socket for a electrical connector to indicate the improved spring properties of the Has spring tongue.
  • This task is carried out by a contact socket with the characteristics of Claim 1 solved.
  • the primary locking provided serves as a single piece with the contact spring trained spring-elastic latch spring tongue, which is exposed to the outside.
  • a major advantage of the contact socket according to the invention is that the current carrying capacity is increased. This is due to the presence of a second one Contact point between base body and contact spring reached. Through that exactly The defined location and nature of the second contact point can be Current resistance of the overall arrangement can be significantly improved.
  • the second contact point is located at a short distance from the connection area in which the connection between the base body and the electrical connection line. On this way, good power transmission with little electrical Resistance can be guaranteed.
  • the contact spring can be designed to keep insertion forces as low as possible that it is formed from two cut spring arms. low Plug-in forces are particularly with multi-pole electrical Connector arrangements important.
  • the contact webs of the two contact arms are set inside like a bottle neck, is a defined pressure on the connector pin guaranteed.
  • the second contact point is designed as a crimp contact, this has the advantage that expensive and complex welded connections are unnecessary.
  • a particularly simple to manufacture and quickly assemble embodiment of the contact spring is the realization of two separate sheets that lie half-shell on top of each other. By connecting these two sheets via a crimp contact, which also serves to connect to the base body, time and costs can be saved during manufacture.
  • the alternative implementation of the second contact point by means of a contact spring pressed against the inner wall of the base body has the advantage that there is no additional crimp region in the connection area of the base body must be provided and thus continue the electrical connector can be miniaturized.
  • the contact spring is U-shaped bent over so that in the inserted state the front edge of the Basic body encompasses. This creates a particularly good electrical transition between the base body and the contact spring and at the same time their secure fit guaranteed against losing.
  • a fastening tab on the contact spring which in the inserted state of the Contact spring fits positively in a receiving pocket on the base body, can prevent the contact spring from being accidentally displaced axially.
  • the contact spring also integrally with the welding point Basic body to be connected.
  • a stable one-piece on the base body and parallel to the latch spring tongue prevents unwanted hooking of the latch spring tongue during the transport of the contact socket.
  • the detent spring tongue be rounded at the end so that it no longer has any sharp edges.
  • the Base body a support spring for the detent spring tongue are provided.
