Definitions

  • This invention relates to electrical connectors and more particularly to a socket type electrical contact mounted within the electrical connector.
  • Electrical connectors generally include a plug and receptacle, each having an insert of dielectric material provided with a plurality of axial passages within which electrical contacts are retained.
  • the contacts are generally pin and socket type contacts that may be removable to facilitate servicing of the connector. Examples of such prior art electrical connectors may be found in U.S. patent 3,221,292 entitled “Electrical Connector” and issued November 30, 1965.
  • An example of a socket type contact may be found in U.S. patent 3,845,459 entitled “Dielectric Sleeve for Electrically and Mechanically Protecting Exposed Female Contacts of an Electrical Connector” and issued October 29, 1974.
  • the socket type contact may be machined from a solid piece of metal or stamped and formed from a thin flat piece of metal such as beryllium copper.
  • the forward mating end of the socket contact includes a plurality of radially and resiliently deflectable fingers which are adapted to engage a pin type contact upon mating with the other half of ar, electrical connector assembly.
  • an outer sleeve or hood is located around the deflectable fingers to protect them from damage as well as to provide a rigid member that will locate the fingers concentrically within the passage in the connector insert. If the fingers are not concentrically located within the insert passage damage to the fingers may eventually result during the mating of the socket type contact with a pin type contact.
  • socket type contacts include an outer hood or sleeve to protect the mating fingers of the socket contact and to locate the socket contact concentrically within an axial passage of the connector insert.
  • the invention eliminates the need for an outer hood or sleeve around the mating portion of a socket contact.
  • the invention is a socket contact of the type having a plurality of resiliently and radially deflectable fingers that are characterized by one half of the fingers being disposed radially outward further than the other half to engage the inner wall of a passage in an electrical insert, thereby locating the socket contact within the insert passage.
  • the remaining fingers extend radially inward further than the other fingers and are adapted to engage a pin type contact upon mating with the other half of an electrical connector assembly.
  • This invention is especially useful in connectors with socket contacts having a diameter of about .6 centimeters.
  • Another advantage of this invention is that electrical contact between a socket and pin contact is established as early as possible upon mating of a connector assembly and hence maintained for a maximum distance during mating and unmating of the connector assembly.
  • FIGURE 1 illustrates an electrical socket type contact 20 having at the mating end thereof a plurality of resiliently and radially deflectable spring fingers 23, 24, 25 and 26.
  • the electrical contact is generally machined from a piece of beryllium copper or stamped and formed from a thin sheet of metal.
  • FIGURE 2 is an end view of the mating end of the socket contacts and illustrates that one half of the spring fingers 21, 23, 25 and 27 extend radially inwardly further than the remaining fingers 22, 24, 26 and 28. It is the function of the fingers 21, 23, 25 and 27 that extend further inwardly to engage an electrical pin type contact (not shown) upon mating with such a contact.
  • FIGURE 3 is a cutaway view of the socket contact 20 located within an axial passage 11 within a connector insert 10. It is the function of every other finger 24,26 to engage the wall of the passage 11 to locate the socket contact 20 concentrically within the axial passage 11 of the insert. The remaining fingers 23 and 25 do not contact the wall of the axial passage 11 in the insert 10 but extend further inwardly to mate with a pin type contact (not shown). Since the only function of the inward fingers 21, 23, 25 and 27 is mating, the taper of these fingers may be such that the forward most portion of each finger 23, 25 and 27 is also the furthest inward portion.
