Definitions

  • This invention relates to electrical connectors. It is the general aim of the invention to provide an improved electrical connector suitable for atomic missile usage and having all lof the advantages of earlier types relating to resistance to adverse environmental conditions, ruggedness of construction, compactuess, and ease of servicing, yet having greatly increased reliability.
  • the present invention proposes utilization of a plug and receptacle wherein both sets of contacts are individually removable by application of properly designed removal tools inserted from the front face of the connector, yet withthe plug body being of the so-called hard front, closed entry type wherein the plug contacts are housed in hard, rigid dielectric material with openings sized to exclude oversize or misaligned pins, so that the likelihood of misalignment of the connector contacts during engagement of the plug and receptacle is minimized.
  • the present invention further proposes a relationship of parts such that, should any signicant misalignment occur, it will infallibly prevent completion of the current path through the connector parts in a manner to be instantly and unquesionably apparent in the pre-flight testing of the missile circuitry.
  • FIGURE l is a greatly enlarged quarter-sectional view through a multiple contact connector of the pin-andsleeve type
  • FIGURE 2 is a fragmental front elevational View of the front face of the plug Ibody of the connector shown in FIGURE 1;
  • FIGURE 3 is a detail perspective of a latch release member utilized in the illustrated connector
  • FIGURE 4 is a perspective view of Contact removal tool adapted to be utilized with the sleeve contacts used in the plug of the connector;
  • FIGURE 5 is a greatly enlarged central sectional view of a contact retention clip as used in both the plug and receptacle, showing its operating relationship with a latch Irelease tube of the plug;
  • FIGURE 6 is a similarly enlarged detail sectional view of a contact retention clip, taken substantially on the plane of the line 6 6 of FIGURE 5;
  • FIGURE 7 is a fragmental sectional view taken through a contact cavity of the plug and showing the mode of operation of the contact latch releasing means therefor;
  • FIGURE 8 is a fragmental sectional view similar to FIGURE 7 but showing the manner -of removal of the sleeve contact from the plug body.
  • the connector receptacle 10 and plug 11 each have an exterior tubular metal shell 12, 13, having the forward ends arranged to telescope within each other and to provide a peripheral seal for the interior of the connector by an O ring 14, carried in the internal groove 15 of the receptacle shell 12.
  • the forward end of the receptacle shell 12 is threaded at 16 to receive a threaded coupling-collar 17 having an internal spring ring 18 seated in an internal groove 19 adapted to bear against the ange 20 of the plug shell 13 to removably draw the plug and shell into coupled relation.
  • the receptacle shell is provided with one or more internal keyways 21 and the forward end of the plug shell has a corresponding key or keys 22 to maintain the desired angular relationship betwen the plug and its receptacle and to thus properly polarize the various individual contacts therein.
  • the receptacle and plug each have a cable support nut 23, 24 threaded to the rearmost end of the shells 12 and 13, with rearwardly extending arms 25 and 26 to support cable clamps (not shown) in the conventional manner.
  • the plug and receptacle each have a multi-part dielectric insert in which the individual contacts are supported.
  • this insert includes a thin, flat, rigid disc 27, generally referred to as an anti-delection disc, transversely disposed in the shell 12 and carrying one or more contact retention clips 28 to support the individual pin contacts of the receptacle.
  • the disc 27 is also preferably provided with a resilient sealing member 29 Ibondedto its forward face and, as shown, has a resilient grommet 30 similarly bonded on its rearward face.
  • each of these parts are locked in the shell 12 by a spring ring 31 each of these parts have aligned apertures in registry with each of the contact retention clips 28, to provide an elongated longitudinal contact cavity 32 running entirely through the insert at the location of each contact.
  • the lrearward ends of each of these cavities, in the area of the resilient grommet 30, have a plurality of sealing risers 33 formed integrally with the grommet.
  • the receptacle portion 10 carries the male contacts which, as shown, include a cylindrical sleeve 34 adapted to receive the insulating layer 3. 35 of a flexible conductor 36 which extends into a sleeve portion 37 of the contact wherein its is held by any conventional means, such as crimping.
  • the contact illustrated has a positioning shoulder 38 from which a shank por- 'tion 39 extends forwardly to a taper 41 terminating in fa reversely facing shoulder 42 on the head portion 43 of 'the contact, which carries the forwardly projecting cylindrical contact pin 44.
  • the connector plug 11 also includes a multi-part di- Aelectric insert including an anti-deflection disc 51 held within the connector shell -by a locking ring 52, with a resilient sealing grommet S3 Ibonded to the rea-r face of the disc and a sealing member -54 similarly bonded on its front face, but in the plug there is also provided a so-called hard front body member 55 formed of hard, rigid, smooth-surfaced insulating material. As shown, the body 55 is of 'generally cylindrical shape, and extends from a generally flat front face 56 to a rearward face 57 whichfmay bear against or be bon-ded tothe sealing member 54.
  • the body member -55 has a rearwardly and outwardly extending flange S engaging a rearwardly facing shoulder 59 on the inside of the plug shell 13 so that the parts 51, 54 and 58 may be held clamped in pressure relationship by the locking ring 52.
  • the anti-deflection disc y51 of the plug is also provided with one or more contact retention clips 61.
  • These clips may 4be identical to the clips 28 of the receptacle and are best illustrated in FIGURES 5 and 6, wherein it will 'be seen that each individual clip 61 consists essentially of a short tubular sleeve 62 having a segmental .mounting flange 63 adapted to be molded into the anti-deflection disc 51 or 27 or secured between plural laminations thereof as shown in FIGURE 5.
  • the sleeve 62 is longitudinally split, preferably by four or tive slots 64 which extend from a point near the mounting flange to the forward end of the sleeve.
  • These lslots divide the sleeve into several independently flexible segments 65, each of which is provided with an inwardly inclined .latch tooth 66 to engage a coacting shoulder of a contact, as later described.
  • Each of the segments 65 of the clip has a forward extending operating member or trigger 67, preferably having a cam surfaced tip inclined outwardly, as will hereinafter appear.
  • each contact cavity 71 has a restricted limiting orifice 73 dimensioned to receive the pin 44 of the male contact, but to encircle it so closely as to preclude insertion of an oversize pin.
  • the tone 73 is provided,fhowever, with a tapered mouth 74, the angular walls of which act as a guide orY funnel to facilitate ⁇ insertion of the pin contacts into the receptacle.
  • each contact cavity also intersect the smooth, tlat front face 56 of the body member 55 in a manner to provide peripheral ridges 76 surrounding each of the contact cavities. It will thus be seen that when the connector is coupled, the pressure exerted by the screw-threaded coupling ring 17 will press the body member 55 tightly against the resilient sealing element 29, establishing an overall seal across the front face of the plug body 4with individual peripheral sealing ridges around each of the individual contact cavities.
  • a peripheral seal around the entire contact assembly is also provided by a small forwardly projecting peripheral flange 77 at the outerl edge of the face 56 of the body member 55.
  • the body 55 is provided with a counterbore 78 to house the sleeve-type contacts of the plug.
  • sleeve contacts of the plug I are similar to the pin contacts of the receptacle in that they have a rearward sleeve 81 to receive the insulating layer 82 of the individual flexible conductors 83 which extend into and are secured within the sleeve 84 at a point behind the collar 85.
  • the shank 86 and taper S8 of the sleeve Contact are also similar to the corresponding parts of the pin contact, to provide a rearwardly facing shoulder 89 similar to the rearwardly facing shoulder 42 and arranged to be engaged -by the several latching teeth 66 on the contact retention clip 61.
  • the forward cylindrical portion 90 of thersleeve contact may be any one of several types, so long as the forward end thereof is apertured to receive the pin 44.
  • the counterbores 78 of the plug body are of considerably larger diameter than the forward sleeve portions 90 of the individual contacts -us'ed therein, so that each cavity has a longitudinal slideway or channel 91, adapted to loosely receive a tubular release member 92 having a tapered rearward end 93 underlying each of the several trigger portions 67 on the Contact retention clip 61.
  • each release tube 92 normally assumes a position as shown in FIGURE l, where it lies immediately behind, but outside of the dimensional limits of the restricted orifice 73 of the contact cavity.
  • the tapered mouth 74 of each contact cavity is, however, provided with one or more latch release keyways, preferably in the form of radial slots 94 (FIGURE 2.) comprising extensions of the latch release channel 91.
  • these keyways are of vwidth sufciently less than the diameter of the pins 44 and corresponding apertures 73 as to preclude acceptance of an oversize pin, and are sized to extend radially at least beyond the inner diameter of therelease tubel in the contact cavity, the fins 97 function to force the.
  • the contacts of both the plug and the receptacle may 'be put in place individually from the rear of each connector insert and may likewise be individually removed, lby access to the front of the insert only.
  • mounting of the contacts is easily accomplished simply by inserting the leading end of each contact into a cavity in the rear gronimet'of the plug or receptacle and sliding the .contact forward with an appropriate tool (not shown) until the plural latch teeth of the collet-type contact rretention clip snap into position behind the locking shoulder of the contact.
  • this action earries the release tube 92'to its forwardmost position due to a light friction drag existing between the sleeve portion 90 of the Contact and the release tube.
  • This friction may be created in any convenient Way, as by a spring linger 99 pierced from the wall of the tube and biasedinwardly to bear against the cylindrical surface of the contact sleeve (FIGURE 3).
  • the restricted pinlimiting apertures 73 and tapered mouth portions 74 of Ithe hard front plug body 55 are so formed as to permit easy insertion of property sized pin contacts 44 and, in fact, to guide the forward tips of such contacts into prefectly mating alignment with the sleeves 90 Ias the plug is coupled to the receptacle.
  • the apertures 73 are sized to prevent insertion of an oversize pin in the contact sleeves 90, however, as seen in FIGURE 2, from which it is apparent that the dimensional limits of the apertures (the inner diameter of the arcuate portions forming the orifice 73) corresponds to the maximum diameter of the contact pin, although the radial keyway slots 94 extend beyond these dimensional limits to permit actuation of the sleeve 92 by insertion of a properly keyed latch release tool.
  • the latch release tool 95 and the latch release tube 92 coact to form latch releasing instrumentalities extending from the forward face 56 of the dielectric insert to the latching means comprising the teeth 66 of the contact retention clips 61.
  • the contact pins Upon coupling of the plug and receptacle the contact pins 'are normally guided in a manner to enter the sleeves of the contacts in accurate alignment, but the arrangement is such that, should one or more of the pin co-ntacts be so deformed as to fail to enter its proper aperture, it cannot possibly establish an intermittent connection. It follows that any defects will invariably be detected during preilight check-out of the circuitry, assuring what has come to be known as go-no-go reliability.
