  • the left end of the coupling ring 16 additionally has a perpendicularly depending portion 40 providing an annular surface 42 spaced from an opposing annular surface 44 provided by the left shoulder of the plug shell flange 38, thereby forming an annular cavity 46 between the coupling ring 16 and the plug shell 18. It is in this annular cavity 46 between the opposing annular surfaces 42 and 44 that the locking memory member 25 is disposed in accordance with the invention.
  • the memory locking member 25 may typically be provided in the form of a ring or washer with serrated outer surfaces 25a and also advantageously including circumferentially spaced memory tabs 25b extending therefrom.
  • the memory locking member 25 is made of a material having controllable mechanical memory properties.
  • the memory material is preferably a metallic alloy comprising an equiatomic nickel-titanium intermetallic compound containing approximately 53 to 57 percent by weight of nickel with the balance titanium. This alloy is customarily referred to in the art as 55-Nitinol.
  • alloys such as 55-Nitinol are only partially understood in the art, and are believed to be a result of a reversible stressinduced, martensitic transformation.
  • An original memory shape may be set into the alloy at an elevated temperature which is typically about 900F for 55-Nitinol.
  • This original shape will be retained after the alloy is cooled.
  • the alloy may then be deformed to a desired intermediate shape.
  • Return to the original shape may then be subsequently accomplished when desired by the application of moderate amounts of heat to bring the alloy to a predetermined transitional temperature range which may be varied by appropriate choice of the particular alloy composition.
  • a transitional temperature range of 60F to 300F may be provided by appropriately changing the percentage of nickel and/or substituting cobalt for nickel on an atomfor-atom basis.
  • the shape recovery temperature range is also dependent on the specific processing history of the alloy. During return of the alloy to its original shape, very considerable force can be exerted thereby so that much mechanical work can be accomplished. Further details concerning SS-Nitinol can be obtained from the article What You Can Do With That Memory Alloy, Materials Engineering, 70, pp. 28-31 (October 1969).
  • the particular original and intermediate shapes chosen for the locking memory member 25 will now be considered in more detail, the intermediate shape being illustrated in FIGS. 13 and the original shape being illustrated in FIGS. 4 and 5.
  • the locking memory member 25 is typically set in accordance with the invention to an original shape having a slightly bowed cross-section with the four circumferentially spaced memory tabs 250 being bent so as to extend radially therefrom as shown.
  • Prior to assembly in the electrical 25 when in its intermediate shape are chosen in the preferred embodiment being considered so that the locking memory member 25 can readily be accommodated within the annular cavity 46 provided therefor (as illustrated in FIG.
  • the coupling ring 16 is designated so as to provide sufficient clearance 48 to permit the memory tabs 25b to extend beyond the ring 16 to an externally visible position.
  • FIGS. 1-10 A second embodiment of the present invention directed to a bayonet-coupled type of electrical connector will next be considered with reference to FIGS.
  • reference numeral 50 generally designates a cylindrical electrical connector comprising a receptacle 62 and plug 64 mechanically coupled together using a conventional bayonet-type of coupling ring 66 rotatably captivated on the plug shell 70 and engageable with a cooperating lug 69 provided on the receptacle shell 68.
  • the receptacle 62 and plug 64 include insulating bodies 72 and 74 respectively disposed within the plug and receptacle shells 68 and 70, and having respective mating contacts 76 and 78 provided therein, all as typically illustrated in FIG. 6. Although only a single pair of mating contacts 76 and 78 are shown in FIG. 6, it will be understood that many more can be provided in a similar manner.
  • an O-ring 80 is provided in an appropriate groove 81 of the receptacle shell 68 for engagement with the outer surface of the plug shell 70 in order to provide sealing for the coupled connector.
  • a helical interior groove. 82 is provided at the left end of the bayonet-type coupling ring 66 (as viewed in FIG. 6) for cooperative engagement with the lug 69 on the receptacle shell in a manner typical of bayonet-type coupling arrangements.
  • the bayonettype coupling ring 66 additionally provides an interior slot 84 for receiving a flange 86 projecting from the plug shell 70, and for also receiving a locking memory member 90 having the general form of a wave washer and preferably made of 55-Nitinol so as to have the memory properties described previously.
  • this wave washer type of locking memory member 90 is retained inthe annular cavity 92 formed between the annular shoulder 94 of the receptacle flange 86 and an opposed annular surface 96 provided for the coupling ring 66 by an insert 98 threaded into the right end thereof.
  • the locking memory member 90 serves to provide a basically similar memory locking function as described in the embodiment of FIG. 1.
  • the locking memory member 90 in conjunction with the flange 86, serves to rotatably captivate the bayonet-type coupling ring 66 on the plug shell 70.
