Definitions

  • the prior art contains many multiple miniature connectors which are designed to receive printed circuit boards or plugs provided with mating multiple-circuit contacts. These connectors generally have resilient metal contacts which are permanently mounted in the connector body and to which wire leads are permanently soldered.
  • the contacts have only a single tlat contact-making surface; which does not assure a good contact, especially under circumstances of severe vibration; and also have inherentlyk a rather low removal force capability.
  • removal force is meant the force necessary to extract the plug from the connector.
  • Thewire leads to the contacts cannot be conveniently removed and replaced; preventing ready modification of circuitry or testing, etc.V
  • a defective contact cannot be removed from the connector body and replaced; resulting in replacement of the entire multiple contact connector.
  • An object of this invention is to provide a connector having contacts of novel coniigura-tion which supply several contact areas capable of making good contact, and which have inherently a very high removal force capability, all lin spite of any severe vibration.
  • Another object of this invention is to provide a connector having contacts to which conductors may be readily connected and disconnected.
  • Yet another object of this invention is to provide a connector having contacts which may be readily remo-vedV and replaced.
  • a feature of this invention is a dielectric body having a ⁇ central cavity containing a plurality of ,spaced-apart contact members, each having a series of reversely-bent elements, at least the innermost element having a longitudinal slit and a mediate bend.
