Definitions

  • stamped and formed electrical contacts are being used more and more as they are less expensive than contacts machined from a single piece of metal. Although stamped and formed contacts are less expensive than machined contacts they are also weaker and more fragile because they are made from sheet metal. For instance, socket type contacts fabricated by stamping and forming methods have spring fingers that are more easily deflectable than machined contacts. This provides less pressure when the spring fingers mate with a pin type contact resulting in an undesirable increase in electrical resistance between the mated contacts. Further, because of the fragility of the stamped and formed inner sleeve, protective sleeves are necessary around the rear wire receiving portion of the sleeve and the forward mating portion. This of course increases the cost of materials as well as increasing the time required to assemble the contact. These problems become even more significant in subminiature type electrical connectors because of the small size of the contacts, 1.25 centimeters long with a .15 centimeter diameter.
  • This invention provides a two piece electrical contact for a subminiature electrical connector that is characterized by a cold drawn socket type contact member and a protective sleeve attached to and around the mating portion of the member.
  • FIGS 1 and 2 illustrate the pieces making up the contact assembly.
  • Figure 1 illustrates a cold drawn tubular member 10 having a forward mating portion that includes a plurality of spring fingers 12 forming a socket type contact.
  • the tubular member 10 is comprised of a metal such as a copper alloy and includes an annular groove 13 adapted to cooperate with a contact retaining mechanism (not shown) within a connector insert.
  • Figure 2 illustrates a sleeve 20 which is adapted to protect the forward mating end of the tubular member 10 shown in Figure 1.
  • Figure 3 illustrates the two piece contact assembly 30 with the sleeve 20 attached to the forward mating portion of the tubular member 10.
