Definitions

  • the disclosure relates to a hermetically sealed electrical connector which is formed of a plurality of contacts which are interconnected by means of a conductive plate.
  • the contacts are connected to the conductive plate and a pair of sealing members which are made of a vitreous material, placed on either side of the conductive plate.
  • the arrangement is mounted in a connector shell and fired so that the sealing members are fused around the conductive plate and to the shell forming a hermetic seal.
  • Contacts which are not connected to the conductive plate may also be sealed to the sealing members.
  • the resultant device provides a hermetically sealed connector having sufficient rigidity and resistance to prevent unwanted physical contact between the members mounted within the connector shell.
  • the invention relates in general to hermetically sealed electrical connectors and, more particularly, to an electrical-connector having interconnected contacts, portions thereof sealed in glass.
  • Hermetically sealed electrical connectors have beenused within a connector to from an effective seal between the connector contacts and the connector shell.
  • Conventional hermetically sealed'electrical connectors utilize organic potting compound to position the contacts within the connector shell.
  • Typical potting compounds utilized previously have been cast epoxy, polysulfide, silicone and polyurethane. It has been found that these materials are vulnerable to both leakage and movement of the buss member. Subsequent electrical failure of the connector, therefore, may result from the entrance of moisture into the potting material. Further, physical contact between adjacent contacts or the contact and the connector shell may result from the adhesive failure of the potting material. Further, the failure of the aforementioned potting compound materials has.
  • the hennetic seal made of glass provides rigidity and resistance to physical shock for those elements mounted in the glass material.
  • the elements adjacent to the glass such as buss plates, which are normally mounted exterior to the glass seal but adjacent thereto, in order to interconnect a selective number of contacts, are still subject to electrical failure when physical shock occurs to the connector.
  • the present invention provides a rigid hermetic seal made of a vitreous material in an area of the connector containing electrical components such as contacts and buss plates. Should the connector be subjected to physical shock, the seal provides sufficient rigidity and resistance to prevent unwanted physical contact between the members mounted within the seal.. Furthermore, the seal arrangement prevents leakage from occurring in the area of the seal.
  • the connector further contains a rear sealing member 36 formed of a vitreous material such as compression glass,
  • a second sealing member 38 made of a similar material as the. member 36, and whose outer diameter is slightly smaller than the inner diameter of the flange portion 26, contains openings 39 therein.
  • the thickness of the second sealing member is approximately equal to the width of the flange 26.
  • an interconnecting means such as a conductive buss plate 42 having openings 43 therein.
  • a plurality of contact members 52 are provided which extend through the openings 37, 43 and 39 and terminate at their rear end at approximately the center of the disc 36 and at their front end forwardly of the disc 38.
  • the connector may also contain standard contacts 54 which extend completely through the openings of the discs 36 and 38 remote from the plate 42 and contain a terminating portion 56 to which the bared end of a conductor wire (not shown) may be soldered or crimped.
  • the contacts 52 and 54 are secured through the openings in the sealing members 36 and 38 and through the openings in the buss plate 42.
  • the buss plate, contacts, and two sealing members are positioned in the connector shell 12 with the outer front surface of the sealing accompanying drawings in which like referenced numerals designate like parts throughout the figures.
  • FIG. 1 depicts an exploded view of a preferred embodiment of the hermetically sealed connector in accordance with the invention
  • FIG. 2 illustrates the connector of FIG. 1, partly in section, prior to sealing
  • FIG. 3 depicts the connector of FIG. I, partly in section, and fully assembled.
  • FIG. 1 An illustration of FIG. 1
  • a polarizing key 24 for aiding in mating with the complementary plug connector.
  • An inwardly extending flange portion 26 is formed on the inner surface 22 and forms a rearwardly facing shoulder 28 and a forwardly facing shoulder 32.
  • the shell 12 further contains a reduced member 36 slightly spaced from the rearward facing shoulder 28 and the front sealing member 38 positioned within the flange 26 as shown in FIG. 2.
  • the shoulder 32 may be utilized as a supporting surface to rest the connector shell on a firing fixture during the fusion operation.
  • an interfacial seal 64 which may be made of silicone rubber and containing forwardly extending protrusions 66, is positioned in front of the second sealing member 38.
  • the interfacial seal contains a plurality of axially extending openings 68 having a diameter approximately equal to the diameter of contact members 52 and 54, which may be inserted through the openings 68.
  • Each of the openings 68 are positioned through the center of the protrusions 66 so that when the contacts are positioned through the interfacial seal, the protruding portions 66 will provide additional support for the contacts.
  • a hermetically sealed electrical connector comprising:
  • said flange having a forward facing shoulder, a rearward facing shoulder, and
