Definitions

  • This invention relates to an electrical connector and more particularly to an electrical contact mounted within the connector.
  • Electrical connectors generally include a plug and receptacle, each of which has an insert of dielectric material provided with multiple openings within which electrical contacts are retained.
  • the insert is introduced into the rear end of a metal shell or housing of the connector where it is held in place by some means, such as a nut.
  • Some connectors provide for rearward insertion and front or rear release of electrical contacts, while other connectors provide for front insertion and front or rear release of electrical contacts. These feature are desirable and facilitate the assembly and servicing of the connector. Examples of a prior art electrical connector having insertable and removable contacts may be found in U.S. Patents 3,165;369 entitled “Retention System for Electrical Contacts" issued July 12, 1966; and 3,221,292 entitled “Electrical Connector” issued November 30, 1965.
  • the contacts are retained within the connector housing by a retention mechanism and the contacts are sealed from moisture by a separate rubber grommet which fits tightly around the incoming wires to prevent moisture from entering into the area between the contacts.
  • a separate rubber grommet which fits tightly around the incoming wires to prevent moisture from entering into the area between the contacts.
  • This invention provides an electrical connector that has insertable and removable contacts retained and sealed against moisture by a one piece molded rubber insert.
  • the invention is characterized by a contact having two annular grooves formed by acutely angled flat surfaces that are adapted to mate with a complementary shaped bore in a rubber insert.
  • FIGURE 1 illustrates an electrical contact
  • FIGURE 2 is a diagrammatic view of an electrical connector incorporating the principles of the invention.
  • FIGURE 1 illustrates a pin-type electrical contact 20 having a central axis A, a forward mating portion 21, an intermediate portion 22 and a rear wire receiving portion 23.
  • the intermediate portion 22 includes two grooves 24 and 25.
  • Each groove 24, 25 includes acutely angled flat surfaces 26, 27.
  • the forward angled surface 26 is at an angle of about 30 degrees from the central axis of the contact.
  • the surface 27 rearward of the forward surface 26 is at an angle of about 15 degrees from the central axis of the contact 20.
  • a rearwardly facing shoulder 28 is located between the intermediate portion 22 and end portion 23.
  • the angle of the surfaces 26, 27 are designed in this embodiment to require a lower removal force from the insert 30 than insertion force. The angles could be reversed if a reverse result is desired, i.e., higher removal force.
  • FIGURE 2 is a diagrammatic view of an electrical connector incorporating the principles of the invention.
  • the electrical connector includes a metal housing 10 and a dielectric insert 30 having mounted therein a male pin-type contact 20 or a female socket-type contact 20.
  • Each insert 30 includes a bore 31 having mounted therein a respective contact 20.
  • Each of the bores 31 in the insert 30 includes two radially inwardly projecting portions or restrictions that mate with the annular grooves 24, 25 in the contact 20.
  • Each bore 31 has an inner diameter that is slightly less than the outside diameter of the contact 20 so as to provide a pressure tight seal around the contact.
  • the angle of the surfaces 26, 27 of each of the grooves 24, 25 determine the retention strength of the contact when it is inserted into the insert 30.
  • a plate 40 comprised of a hard dielectric material, is fixedly mounted within the housing 10.
  • the rear shoulder 28 of the contact 20 abuts against a forwardly facing shoulder 23 on the plate 40 to prevent further rearward movement of the contact 20 in the insert 30.
  • the plate 40 acts as a positive stop when a contact 20 is inserted into the bore 31 of the insert 30 from the front of the connector housing 10.
  • the insert 30 is comprised of an elastomer such as rubber and preferably has a durometer of about 65.
