Definitions

  • the present invention relates to the field of electrical connectors and more particularly to matable connectors which are matchingly keyed.
  • Certain electrical connectors are to be mated to mating connectors with mating arrays of terminals thereof to become electrically engaged along connector mating faces. Where a plurality of similar such connectors are located adjacent each other in an array, for mating to a like plurality of mating connectors, the connectors must be labeled or otherwise visibly marked to indicate which of the mating connectors all similar in appearance and shape, are to mate with which of the mounted connectors all similar in appearance and shape.
  • Types of connectors are known in which cooperating keying structures are utilized which are shaped and positioned and correspondingly oriented along the respective mating faces of the pair of connectors to allow mating when the two connectors matchingly keyed are being moved axially together, but abut and physically obstruct mating when two connectors are being moved together which are not matchingly keyed.
  • Such keys are usually used in pairs matable with corresponding pairs and usually have body sections which are hexagonal or (octagonal) in cross-sectional shape, and the keys of each pair are secured to a respective one of the connectors with their body sections in apertures of the connector housing which are correspondingly shaped in cross-section; thus each key can be secured in its respective aperture in any one of six (or eight) different positions, respectively.
  • Each key includes a keying projection extending axially forwardly from the body section but only extending around about one half of the circumference; the corresponding key will have a keying projection which will enter the region comprising about the remainder of the circumference, when the two connectors which are matchingly keyed are moved axially together.
  • connectors are also known in which a pair of jackscrews are utilized to hold the connectors together in mated relationship by extending from one connector to a threaded aperture of the other along the mating face, where each jackscrew is rotatable to bring the connector mating faces assuredly together in the last stages of mating.
  • a pair of jackscrews are utilized to hold the connectors together in mated relationship by extending from one connector to a threaded aperture of the other along the mating face, where each jackscrew is rotatable to bring the connector mating faces assuredly together in the last stages of mating.
  • polarizing members are disposed in apertures of lateral flanges of molded plastic housings and have three circumferentially spaced polarizing projections extending forwardly of the leading ends of the connector housings.
  • a jackscrew extends through a central passageway of each member of one of the connectors and has a threaded forward shank end extending forwardly of the polarizing projections.
  • the opposing member includes a threaded insert axially rearwardly of the projections to be threadedly engaged by the threaded jackscrew end during fastening after connector keying.
  • Threaded engagement between the jackscrew and the insert occurs after the polarizing projections of the polarizing members have moved past each other along most of their lengths.
  • the reference also discloses a mechanism for preventing overtorque during turning of the jackscrew, by allowing rotation of the threaded insert after a certain torque level has been reached as the connectors are completely mated.
  • Other prior art discloses using jackscrews with polarizing hardware or assembled to serve a polarizing function include U. S. Patents Nos. 2,902,665 and 2,746,022.
  • a connector mounted to a printed circuit board includes a key member which includes a threaded aperture rearward of the keying projection and is adapted to be threadedly engaged by a correspondingly threaded forward shank end of the jackscrew extending from a corresponding key of the mating, matchingly keyed connector. If the mating connectors were not matchingly keyed, the opposing keying projection forward ends would abut, the connectors would not mate, and the forward jackscrew end would not enter the threaded key aperture to fasten the connectors together.
  • the present invention provides for securing the keys to the connectors away from the contact region of the mating faces thereof, by securing the keys to the lateral flanges defined by the shell members of the connectors.
  • the mounting aperture of each flange of each shell member includes a forward region having a correspondingly hexagonal shape formed into the metal, and a rearward region of the mounting aperture remains conventionally circular with a smaller diameter.
  • Each of the key members includes a body section having the hexagonal cross-sectional shape to be seated in the correspondingly shaped aperture region which will prevent rotation of the key member after mounting. Forwardly from each body section extends the appropriate keying projection, and rearwardly therefrom extends the mounting section through the circular small diameter mounting aperture region.
  • One of the key members (termed herein a mounting key) is adapted to receive a jackscrew member mounted therealong, while the other key member (a mating key) is adapted to be threadedly engaged by a forward threaded end of the shank of the jackscrew member upon connector mating, where the connectors are matchingly keyed.
  • the jackscrew member includes a forward shank portion which is threaded, and the keying projection of the mounting key defines a generally semicircular hood which is radially spaced from and coextending forwardly along the jackscrew shank to a leading end forward of the jackscrew forward end; the hood is defined by an inner cylindrical surface coaxial with the jackscrew shank, and an outer surface defined by three adjacent flat surfaces comprising three sides of a hexagon.
  • the mounting key of the present invention includes a profiled aperture having a larger diameter forward portion within which a larger diameter body section of the jackscrew is seated, and a smaller diameter rearward portion through which extends a smaller diameter jackscrew mounting section, with both of the aperture portions dimensioned to allow the jackscrew to be rotated freely within the mounting key after assembly.
  • the jackscrew includes a rearward shank portion extending rearwardly, and a slotted jackscrew nut is placed thereon, and a roll pin is inserted transversely through aligned small holes to secure the nut on the jackscrew and the jackscrew to the connector in a manner permitting rotation relative to the connector and the mounting key seated therein, with the roll pin being removable to permit disassembly if desired.
  • At least a portion of the connector shell peripherally surrounding the contact region of the mating face extends to a leading end just forwardly of the hood-shaped keying projection leading end, with the mounting key and the jackscrew leading ends thus not extending forwardly of the forward shell leading end; the shell thus provides a measure of protection against damage or misalignment during handling for the mounting key and jackscrew shank by extending radially therearound except along the flange end surface.
  • the mating key includes a keying projection which is generally a sleeve having a central bore thereinto which is threaded to be engaged by the forward jackscrew end upon connector mating.
  • the keying projection extends radially outwardly to three flat side surfaces defining half of a hexagon extending around half of the periphery of the sleeve, while the remainder of the sleeve periphery is defined by a cylindrical surface of an appropriate small diameter thereby defining an axial recess and being adapted to receive therealong the hood-shaped keying projection of the mounting key upon connector mating when the connectors are matchingly keyed, as the jackscrew shank is threadedly received into the central bore upon rotation of the jackscrew.
  • the mating key includes a rearward shank portion extending rearwardly from the connector and includes an annular slot for a fastening mechanism to be secured thereon to secure the mating key to the connector, in a manner permitting disass
  • the hexagonal forward aperture region may be a recess extending transversely into the side surface of a flange end and have opposed side walls and an inward wall defined by flat surfaces and having three portions corresponding to three adjacent sides of a hexagon which is centered about the circular small diameter mounting aperture region.
  • the connector shell comprises a forward formed or drawn shell member clinched by tabs to a rearward shell member enclosing the housing therewithin. Lateral flanges of both coextend out from the contact region; a hexagonal seating aperture extends through the lateral flange of the forward shell member; a circular small diameter hole extends through the rearward shell member aligned with the seating aperture.
  • the mating and mounting keys include chamfered surfaces at their leading ends to facilitate the keying projections passing by each other at initial stages of mating which constitutes the keying engagement.
  • the jackscrew leading end also is rounded or tapered to facilitate entry into the threaded aperture of the mating key.
  • the keying and fastening system thus is adapted to allow for slight misalignment of the keys and jackscrews by providing for self-adjustment of the alignment, since the hardware is secured to a pair of thin plate shells having minimal engagement with rearward portions of the keys and jackscrews axially therealong, which otherwise would commonly not provide for assured perpendicular alignment thereof.
  • Connector assembly 100 comprises a pair of matable electrical connectors 10,110 as shown in Figure 1 and are matchingly keyed using the keying and jackscrew hardware according to the present invention.
  • Connectors 10,110 have shell members 12,112 with shell 12 having a forward hood section 14 which is receivable into large cavity 114 of shell 112 upon keying, mating and fastening of the connectors; forward hood section 14 and large cavity 114 are correspondingly dimensioned and D-­shaped for polarization so that mating of the connectors occurs when both connectors are at least appropriately oriented with respect to each other, as is known.
  • forward hood section 14 of shell 12 is adapted to surround a forward plug section 16 of dielectric housing 18 in which socket terminals 20 are secured with their socket contact sections recessed within respective passageways 22.
  • Connector 10 is adapted to be mounted to an edge of a printed circuit card (not shown) by pairs of rearward card-receiving flanges 24 defining card-receiving slots, and terminals 20 include cantilever beam contact sections extending rearwardly to be soldered to respective conductive traces on the card.
  • connector 110 large cavity 114 of shell 112 is situated forwardly of the mating face 116 of dielectric housing 118, with pin contact sections of terminals 120 mounted in the housing extending forwardly of the mating face to matingly engage socket contact sections of terminals 20 of the mating connector 10.
  • Terminals 120 are shown having post sections extending rearwardly for mounting in respective plated through-holes of a printed circuit board (not shown).
  • Such a connector assembly 100 is generally known in Part Nos. 534776 and 534777 sold by AMP Incorporated, Harrisburg, Pennsylvania, and from U. S. Patent No. 4,715,829.
  • shell 12 includes a flange 26 at each end laterally of the hood section 14.
  • Flange 26 includes an aperture 28 extending therethrough providing for securing a key member 30 to shell 12.
  • Key member 30 includes a keying projection 32 having a threaded bore 34 thereinto from leading end 36, a hexagonal body section 38, and a rearward mounting section 40 having an annular recess 42 thereinto to receive a C-shaped locking ring 44 thereinto when assembled to flange 26.
  • Mounting section 40 extends through aperture 28 so that annular recess 42 is exposed just rearwardly of rearward flange surface 46.
  • a slot 48 is formed in the shell where rearward flanges 24 extend from flange 26, so that C-shaped locking ring 44 is insertable thereinto to snap around key mounting section 40 within annular recess 42 and is accessible to be removed if desired for disassembly.
  • Flange 26 also includes a recess 50 forwardly of aperture 28 shaped to define a seat for key body section 38 and include at least four sides of the hexagon closely corresponding to four sides of the hexagonally shaped body section 38, in order to hold key 30 against rotation after assembly.
  • the key members and corresponding seating apertures could also have the shape of an octagon or other regular polygon.
  • Keying projection 32 includes around about half of its periphery a series of three adjacent flat side surfaces defining three sides of a hexagon, which may extend forwardly from three sides of the hexagonally cross-sectioned body section 38.
  • the other half of the periphery comprises a semicylindrical surface having a radius smaller than the general cross-sectional dimension of the body section 38, thus defining an axial recess of arcuate shape extending from leading end 36 to body section 38.
  • Shell 112 includes a flange 126 at each end laterally of large cavity 116.
  • Flange 126 includes an aperture 128 extending therethrough providing for securing a key member 130 to shell 112.
  • Key member 130 includes a keying projection 132 shaped like an elongate semicylindrical hood having an arcuate inner surface 134 extending forwardly to a leading end 136, the key member further including a fully hexagonal body section 138, and a rearward mounting section 140.
  • Hood-shaped keying projection 132 is adapted to be received along the axial recess of keying projection 32 of mounting key 30 during mating of connectors which are matchingly keyed with the mating and mounting keys secured in cooperating keying orientations.
  • Mounting section 140 extends along but entirely within flange aperture 128; body section 138 is disposed within elongate recess 150 which extends inwardly from an end of shell 112 and forwardly to the forward face 152 of shell 112.
  • Elongate recess 150 is defined by flat side surfaces forming four adjacent sides of a hexagon and closely correspond to four sides of the hexagonal body section 138 to prohibit key rotation after assembly.
  • Jackscrew 160 is assembled to shell 112 of connector 110 along with key 130.
  • Jackscrew 160 includes a forward shank 162 extending to a leading end 164 and is threaded therealong to correspond with threaded bore 34 of key 30 of mating connector 10.
  • Rearwardly from forward shank 162 is a large diameter seating section 166, and rearwardly therefrom extends a smaller diameter mounting section 168.
  • Body section 138 of key 130 includes a large diameter forward hole portion 142 corresponding to jackscrew seating section 166, and a smaller diameter rearward hole portion 144 corresponding in diameter to jackscrew mounting section 168, so that jackscrew 160 is inserted through key 130 for assembly with jackscrew seating section 166 seated within forward hole portion 142 and mounting section 168 extending rearwardly from key section 140.
  • Jackscrew mounting section 168 may optionally include an annular recess located where section 168 exits from the shell's rearward surface into which a C-shaped locking ring (not shown) is snapped to provide a temporary means for holding jackscrew 160 and perforce mounting key member 130 to shell 12 during assembly, facilitating assembly of the keying and jackscrew hardware.
  • a jackscrew nut 170 is mounted to the rearwardly extending jackscrew mounting section 168 by means of a roll pin 172 inserted in an interference fit transversely through pin-receiving hole 174 of nut 170 and through pin-receiving hole 176 through jackscrew mounting section 168 aligned with hole 174.

  • Nut 170 is slotted for example to be rotated by a tool such as a screwdriver when it is desired to rotate jackscrew 160 to fasten connectors 10,110 together after keying for full mating, and nut 170 may also be knurled to enable manual rotation if desired.
  • Jackscrew 160 is dimensioned to be rotatable within forward and rearward hole portions 142,144 of key 130.
  • Shell recess 150 provides physical protection axially along and surrounding most of the periphery of keying projection 132 and jackscrew shank 162 to prevent damage and misalignment thereof during handling.
  • a connector assembly 300 comprising a pair of matable electrical connectors 210,310 are shown in Figure 5 which are matchingly keyed, according to the present invention.
  • Connector 210 has a forward plug section 216 which is receivable into large cavity 312 of hood section 314 of connector 310 upon mating; forward plug section 216 and hood section 314 are correspondingly dimensioned and D-shaped for polarization so that mating of the connectors occurs when both connectors are appropriately oriented with respect to each other, as is known.
  • Forward plug section 216 has a plurality of terminals 218,220 having socket contact sections disposed in passageways 222,224 in communication with mating face 226 of connector 210, while connector 310 has a like plurality of terminals 318,320 having pin contact sections extending forwardly from mating face 322 within hood section 314 which will be received into entrances to passageways 222,224 and into the socket contact sections of terminals 218,220 of connector 210 upon mating.
  • connector 210 includes a forward shell member 228 and a rearward shell member 230 which together define a protective shell containing housing inserts 232,234 and terminals 218,220 ( Figure 5).
  • shell members 228,230 are stamped and drawn from steel into thin-walled members and then preferably cadmium plated.
  • Shell members 228,230 include respective housing apertures 236,238 extending axially therethrough and transverse peripheral flanges 240,242 surrounding housing apertures 236,238, and extending laterally from opposed ends of the shell members are lateral flanges 244,246.

  • Through lateral flanges 244,246 extend holes 254,256 aligned with each other when the shell members are clinched together.
  • Connector 310 of Figure 5 is similarly constructed, with forward and rearward shell members thereof having apertured lateral flanges.
  • key member 260 includes a keying projection 262 having a threaded bore 264 thereinto from leading end 266, a hexagonal body section 268, and a threaded rearward mounting section 270.
  • Mounting section 270 extends through apertures 254,256 and rearwardly of rearward flange surface 246 onto which a nut 272 is secured along with lock washer 274.
  • Aperture 254 forwardly of aperture 256 is shaped to define a seat for key body section 268 in order to hold key 260 against rotation after assembly, in conjunction with forwardly facing surface portion 258 of rearward shell flange 246 surrounding smaller diameter aperture 256 against which is disposed a rearwardly facing surface 276 of key body section 268.
  • the key members and corresponding seating apertures 254 could also have the shape of an octagon or other regular polygon.
  • Keying projection 262 includes around about a first half 278 of its periphery a series of three adjacent flat side surfaces defining three sides of a hexagon, which may extend forwardly from three sides of the hexagonally cross-sectioned body section 268.
  • the second half of the periphery comprises a semicylindrical surface 280 having a radius smaller than the general cross-sectional dimension of the body section 268, thus defining an axial recess of arcuate shape extending from leading end 266 to body section 268.
  • Leading end 266 is chamfered along the outer edge at 282 adjacent semicylindrical surface 280.
  • Forward and rearward shell members 328-330 of connector 310 include flanges 344,346 at each end laterally of hood section 314.
  • Flange 344 is similar to flange 244 of shell 228 and includes a hexagonal seating aperture 354 extending therethrough providing for seating of a key member 360 in conjunction with forwardly facing surface portion 358 of rearward shell flange 346 surrounding smaller diameter aperture 356.
  • Key member 360 includes a fully hexagonal body section 368 which is seated in aperture 354 with rearwardly facing surface 370 against flange surface 358, to prohibit key rotation after assembly.
  • the key member further includes a keying projection 362 shaped like an elongate semicylindrical hood having an arcuate inner surface 364 extending forwardly to a leading end 366.

  • Leading end 366 is chamfered at 372 adjacent semicylindrical inner surface 364.
  • Chamfer 372 will cooperate with chamfer 282 during initial stages of connector mating to enable keying projections 262,362 of key members 260,360 to pass by each other where they are matchingly oriented to permit keying but may be slightly angularly misaligned.
  • Jackscrew 380 is assembled to connector 310 along with key 360 and defines the means for securing key 360 to the connector.
  • Jackscrew 380 includes a forward shank 382 extending to a leading end 384 and is threaded therealong to correspond with threaded bore 264 of key 260 of mating connector 210.

  • Body section 368 of key 360 includes a large diameter hole 374 corresponding to jackscrew seating section 386, and further includes a smaller diameter hole portion 376 rearwardly thereof concentric therewith, so that jackscrew 380 is inserted through key 360 for assembly with jackscrew seating section 386 seated within hole portion 374 and mounting section 388 extending rearwardly through hole portion 376 from body section 368 of key 360 and through circular aperture 356 of flange 346 of rearward shell member 330.

  • a jackscrew nut 394 is then mounted to the rearwardly extending jackscrew mounting section 388 by means of a roll pin 396 inserted in an interference fit transversely through pin-receiving hole 398 of nut 394 and through pin-receiving hole 400 through jackscrew mounting section 388 aligned with hole 398.
  • Roll pin 394 is easily removed by simple tools if desired for replacement of parts or re-orientation of key member 360.
  • Nut 394 is slotted for example to be rotated by a tool such as a screwdriver when it is desired to rotate jackscrew 380 to fasten connectors 210,310 together after keying for full mating, and nut 394 is also knurled to enable manual rotation.
  • Jackscrew 380 is dimensioned to be rotatable within hole portions 374,376 of key 360.
  • Leading end 384 of jackscrew 380 is preferably rounded or tapered at least peripherally therearound. The benefits of such a shape are that leading end 384 is enabled to enter the corresponding threaded aperture 264 of mating key 260 even if jackscrew 380 is slightly angularly misaligned with respect to aperture 264, and jackscrew 380 will be urged slightly into alignment to enable threaded engagement.
  • the shells provide little assurance of precise alignment of the keys and jackscrews to be perpendicular to the shell flanges because of not engaging the shaft portions at two substantially spaced axial locations therealong as is inherent in most electrical connectors either in plastic housings or in surrounding shell members.
  • the present invention provides a means for overcoming the resultant slight angular misalignment of the keys and jackscrews inherently through angular adjustment thereof upon connector mating.
  • the rearward surfaces 276,370 of the body sections of both key members 260,360 are held against the front surfaces 258,358 of rearward shell members 230,330 respectively after mounting.
  • the forward shell member 228,328 although comprising a thin plate, defines a means for preventing the rotation of the respective key member body section 268,368 after mounting in a selected angular orientation.
  • the pair of thin plates which comprise the flanges of the connector shells 328,330 also define a means in conjunction with the key members 360 of the present invention, for securing jackscrews 380 to connector 310, and also a means for connector 210 to cooperate with the threaded jackscrew forward end of connector 310 to comprise a means for fastening connectors 210,310 together to define mated connector assembly 300.
  • jackscrew nut 394 is disposed closely adjacent to the rearwardly facing surface of rearward shell 330 of connector 310 after roll pin 396 is affixed in a manner permitting jackscrew 380 to remain rotatable after mounting, to stabilize the angular alignment of jackscrew 380 by reason of coextending axially along a substantial length of jackscrew mounting section 388.
  • the jackscrew leading end 164 is recessed behind the leading end 136 of the keying projection 132 of mounting key 130.
  • Leading end 164 of jackscrew 160 thus is shaped and positioned not to extend forwardly of leading end 136 of keying projection 132 or the forward face of shell 112 in a manner which would otherwise render the jackscrew leading end susceptible to being at least laterally stressed upon incidental engagement therewith by foreign objects.
  • Jackscrew 160 thus has a significant measure of protection from damage during connector handling which otherwise could lead to misalignment of the jackscrew and prevent fastening and connector mating.
  • FIG. 5 the keying and mating capabilities of connectors 210,310 is illustrated, wherein the advantages of the present invention can be discerned.
  • the jackscrew leading end 384 is recessed behind the leading end 366 of the keying projection 362 of mounting key 360, and both leading ends are recessed slightly behind the forward end 324 of hood portion 314 of shell member 328.
  • Jackscrew 380 thus has a measure of protection from damage during connector handling which otherwise could lead to substantial angular misalignment of the jackscrew or even twisting of flanges 344,346 ultimately preventing fastening and connector mating.
  • the mounting key members 130,360 of connectors 110,310 and mating key members 30,260 of connectors 10,210 are angularly oriented to cooperate with each other to permit mating since the opposed connectors are desired to be matable and have been matchingly keyed.
  • the outer edges of leading ends 36,266 of keying projections 132,262 are preferably chamfered, and the inner edges of leading ends 136,366 of keying projections 132,362 are also chamfered, to enable incremental adjustment in the angular orientation of the respective key members 30,130;260,360.
  • any of the key members of one connector were not angularly oriented to correspond with the opposed key member of the other connector, the key members would abut before the jackscrews would begin to enter the opposing threaded key bores and thus prevent fastening; and the connectors and their terminal arrays could not mate. Also, if a jackscrew were to be misaligned during handling, full threaded engagement would be adversely affected or even prevented thus preventing full connector mating even if the connectors were matchingly keyed, a condition which the present invention minimizes.
  • Shells 12,112 of Figures 1 to 4 as shown are formed by being machined of aluminum and anodized, which facilitates forming flat side surfaces of recesses 50,150 in communication with apertures 28,128 and also forming of rearward flanges 24 and ring-receiving slot 48.
  • connectors 10 of Figures 1 to 4 are mountable to edge portions of an array of printed circuit cards during assembly of the electronic apparatus, and the angular orientations of each key member 30 of each of the connectors 10 may be selected during apparatus assembly.
  • Connectors 210,310 are adapted to have their keys, jackscrews and mounting accessories easily assembled at the site of an array of a plurality of like connector pairs, and also easily disassembled if desired. This assures that each connector in an array of up to thirty-six like connectors can be physically coded to be distinct from others of the same array.
  • each connector being polarized by the D-shaped forward plug section and having two key members of hexagonal shapes, thirty-six coding possibilities exist; if octagonal keys are used, then sixty-four coding possibilities would exist.
  • the keying system of the present invention provides for mechanical coding to prevent non-matchingly keyed connectors from being mated.
  • a means is provided for securing the keys and jackscrews to the connector shells in a manner permitting the person applying the connectors at the site of in-service use to determine the keying orientations in order to encode the connectors in the context of the connector array being defined at the site.
  • the securing means permits easy disassembly for re-orientation of keys if desired, or replacement of parts if necessary.
