Definitions

  • This invention relates to a programmable sealed electrical connector assembly having a secondary lock to secure contact terminals and further having stamped and formed cylindrical pins with a sealed plug in the interior thereof.
  • U.S. Patent 4,767,350 discloses a multiconductor sealed connector suitable for use in terminating a plurality of wires to a printed circuit board.
  • This sealed connector uses stamped and formed pins in the pin header and employs both an interfacial seal and a single family seal having a plurality of holes each receiving a single wire.
  • This connector does not employ a secondary lock.
  • U.S. Patents 4,557,542, 4,319,799, 4,655,525, 4,787,864 and 3,601,760 disclose electrical connectors which employ secondary locking members with connectors having two rows of terminals. Furthermore, each of the aforementioned electrical connectors employ a secondary locking member which comprises a separate piece and must be inserted into the housing after the contact terminals have been positioned within the housing.
  • U.S. Patent 4,708,662 discloses a connector assembly with a prestaged terminal retainer secured to the main body of the housing at the rear of the housing. This terminal retainer has a plurality of resilient fingers having a conical configuration. These resilient fingers retain the terminals in position.
  • U.S. Patent 4,443,048 and U.S. Patent 4,544,220 disclose connectors also having resilient fingers engaging terminals. These retainer members can be attached to the soft shell housing of an electrical connector after the terminals are secured within the retainer.
  • the device shown in U.S. Patent 4,443,048 does not employ any secondary locking feature.
  • the electrical connector shown in U.S. Patent 4,544,220 does employ a secondary locking capability.
  • None of these conventional electrical connectors provide for dense population of electrical terminals in multiple rows in a secondary lock connector.
  • the instant invention provides such a configuration.
  • U.S. Patent 4,760,350 discloses a sealed receptacle and plug connector assembly for use in terminating a plurality of conductors to a printed circuit board.
  • Stamped and formed pins located in a pin header include rear section which is bent at right angles and is secured to the rear of the header. The front of the stamped and formed pins are stamped into a cylindrical configuration. These cylindrical or tubular pins have a seam line where portions of the flat metal blank forming the tubular pin abut. The seal which can be established along the seam line exhibit limited performance capabilities.
  • the instant invention provides a means for sealing a stamped and formed pin in an electrical connector which provide enhanced performance over that previously exhibited by the prior art.
  • an electrical connector assembly which includes a receptacle connector having terminals secured in a housing by latches which are received in pockets in a secondary housing mated to the housing, a secondary lock on the housing which shifts to a proper position when the latches secure the terminals and further includes a pin header having pins in a header housing with sealing plugs provided within the pins.
  • the sealed electrical connector assembly comprising the preferred embodiment of this invention is intended for use in establishing sealed interconnection to conductors in a densely populated array.
  • the sealed connector assembly 2 comprising the preferred embodiment of this invention be used with conductors at any arbitrary location, less than the total number of terminal position in the housing. Sealing integrity is established with each of the electrical conductors, such as wires, and sealing integrity can be established with individual wires and along individual circuits even though all of the positions in the connector are not filled with terminals.
  • Electrical connector or receptacle connector 6 is employed to mate with a mating connector or shrouded pin header 8. Electrical terminals 10 are mounted in the electrical connector 6 in a plurality of rows.
  • terminals 10 are mounted in three rows, the center row being staggered with respect to the terminal positions in the outer two rows.
  • Terminals 10 are attached to wires 4 and are matable with stamped and cylindrically formed or tubular pins 20.
  • Terminals 10 are positioned within an insulative housing 30 and the pins 20 are positioned within a header housing 140 of the pin header 8.
  • Each of the terminals 10, as shown in Figure 14, include a plurality of contact springs 12 which are in the form of cantilever beams positioned within a tubular or barrel contact section 14. In the preferred embodiment of this invention these contact springs 12 extend forwardly from the rear of the barrel shaped sections toward the front.
  • a shoulder 15 is formed at the rear of the barrel contact section 14 and a waist section 16, having a reduced outer diameter, is formed between the barrel contact section 14 and a stabilizing section 17 having an outer diameter substantially equal to the outer diameter of the barrel contact section 14.
  • Barrel shoulder 15 forms a well defined shoulder between the barrel contact section 14 and the waist section 16.
  • a conventional wire crimp section 18 is located adjacent the cylindrical stabilizing section 17 and an insulation crimp 19 of conventional wrap around construction is located at the rear of terminal 10. The terminal is crimped in such a manner that the elastomeric seals will not be damaged when a crimped terminal is inserted through the seal.
  • Each terminal 10 can be crimped to a stripped end of a wire 4 in
  • Terminals 10 are positioned within a insulative housing 30 having an insulative base 32 through which a plurality of openings or cavities extend in rows corresponding to the rows in the array of terminal positions. These openings or cavities 36 form means for positioning terminals in three staggered rows extending between opposite end walls 38 of the insulative housing 30 and parallel to opposite sidewalls 40.
  • Housing 30 has a mating face 34 in the shape of a rectangular mating envelope formed by opposite end walls and opposite sidewalls. The end walls 38 and sidewalls 40 forming this mating envelope extend forward from the insulative housing base 32.
  • Insulative housing 30 is open within the envelope formed by end walls 38 and sidewalls 40 from the insulative housing base forward.
  • a plurality of grooves 46 are provided in each sidewall 40. In the preferred embodiment of this invention the grooves 46 in the upper sidewall are spaced apart by different distance than the grooves 46 in the lower sidewall. The grooves 46 thus polarize the mating envelope formed at the mating face 34 of the insulative housing 30.
  • An insulative housing shroud 42 is located at the rear end of the insulative housing and extends rearwardly from the insulative housing base 32. Housing shroud 42 protrudes beyond the sidewalls 40 and beyond the end walls 38 such that the mating envelope has smaller outer dimensions than the housing shroud 42. A shoulder is formed at the juncture between the end walls 38 and the sidewalls 40 forming the mating envelope and the housing shroud 42. A plurality of grooves 48 adjacent the rear end 44 of the housing are also formed in the shroud 42. Again, grooves in opposite walls of the housing shroud are located in a different configuration on the top and bottom walls of the shroud 42 to polarize the housing shroud.
  • a plurality of resilient plastic latches 50 integral with the insulative housing 30 extend from the insulative housing base 32 towards the mating face 34.
  • Each of these latches 50 comprises means for securing terminals in the insulative housing.
  • Latches 50 are located on the interior of end walls 38 and sidewalls 40 within a large mating cavity on the insulative housing.
  • Each of the latches comprises a resiliently deflectable beam extending from base 32.
  • each of the latches 50 has a generally triangular cross section with exterior surfaces 54 of each latch converging towards an apex 52 with distance away from the respective terminal 10 secured by the latch.
  • each latch 50 converge towards an apex 52 with distance away from the center line of the opening 36 in the insulative base 32.
  • Two latches, positioned in surrounding relationship to each terminal 10 protrude from the insulative housing base 32 on the periphery of each opening 36 to secure each terminal extending through and positioned by each corresponding opening 36. Since the exterior surfaces 54 of each opposed pair of latches 50 converge towards opposite apices 52, each opposed pair of latches generally forms a diamond shape configuration.
  • Engaging surfaces 58 in the form of curved lips protrude inwardly from the triangular shaped cantilever beams 56 forming the latches 50. These engaging lips 58 protrude into the cylindrical contour of the openings 36 and provide a means for gripping a terminal 10 inserted through an opening 36.
  • the latches 50 in each row are staggered with respect to latches 50 in an adjacent row.
  • the tapered latches 50 can be positioned in partially overlapping relationship. In this manner the rows of terminal positions in the terminal array can be more closely spaced. In other words, openings 36 can be more closely spaced. In this manner a denser population of terminal positions can be achieved.
  • the apices of latches in each outer row overlap the apices 52 of latches 50 in the adjacent center row.
  • Secondary housing member 60 mountable in telescoping relationship to the front of the insulative housing 30, comprises a secondary lock.
  • Secondary lock 60 is shiftable from a first position shown in Figures 6 and 7 to a second position shown in Figure 8.
  • Secondary lock 60 has a plurality of pockets 62 arranged in a plurality of rows in the secondary lock 60.
  • individual pockets are substantially diamond shaped with the apices 64 of pockets in adjacent rows overlapping.
  • the pockets are located in three rows with the pockets in the center row be staggered with respect to pockets in the outer two rows.
  • pockets 62 only partially overlap pockets in adjacent rows.
  • the pockets 62 are formed by diagonal wall sections 66 which are interwoven to define a honeycomb structure.
  • Diagonal wall section 66 extend rearwardly from an outer secondary housing member base or outer partition 68.
  • Apertures 70 in the form of generally circular holes, having a tapered end adjacent the outer face of the secondary lock 60, have a generally circular or cylindrical shape and each aperture 70 is aligned with a corresponding diamond shaped pocket 62.
  • the diagonal wall section 66 located beyond each aperture 70 such that the diamond shaped pocket 62 align with aperture 70 are generally larger than the aperture 70.
  • the diagonal wall sections are located only on the interior of the secondary lock 60 and extend from the rear of the aperture 70 to the rear end of the secondary lock 60. Note that the apertures 70 have generally circular cross-section which merges with the diamond shaped cross-section of the pocket defined by the diagonal wall sections 66.
  • each aperture 70 is offset from diagonal wall section 66 in a secondary lock 60 so that mating terminals in the form of pins 20 can be inserted through apertures 70 and the pins will be spaced from the diagonal wall sections 66.
  • the shape of the latch pairs 50 and the corresponding pockets 62 are substantially the same so that the latches 50 can be inserted into corresponding pockets 62. Latches 50 are however received in respective pockets 62 only when the secondary lock 60 is in the second position shown in Figure 8 and when the latches 50 are in a position securely engaging corresponding terminals 10.
  • Secondary lock 60 includes a plurality of tongues 72 extending outwardly from opposite sidewalls 40.
  • the tongues merge with a laterally extending platform 74 so that each tongue and platform essentially has a T shaped configuration.
  • Tongues 72 are positioned to correspond with the location of grooves 46 on the top and bottom sidewalls 40 of housing 30. Tongues 72 interfit with the grooves 46 so that the pattern of tongues and grooves provide a keyed orientation between the insulative housing and the secondary lock 60.
  • the integral tongue 72 and platform 74 also provide a means for orienting or keying the connector 6 with respect to a mating connector 8 since these T-shaped tongues and platform configurations are located adjacent to mating face of connector 6.
  • Secondary lock 60 can be attached to the insulative housing 30 in the first position of figures 6 and 7 as well as in the second position shown in Figure 8 by a two position retainer means comprising a finger 85 on the sidewalls 38 of the insulative housing 30 which is engagable with spaced apart mating shoulders 84 and 86 on the ends of the secondary lock 60.
  • the two position retainer means also includes an outer strap 80 which overlaps fingers 85 when the secondary lock 60 is in the closed second position.
  • Mating shoulders 84 and 88 are located within a channel 82 on one end of the secondary lock 60.
  • Two internal shoulders 84 are located on two spaced apart ridges 86a and 86b located adjacent to the edges of channel 82.
  • Shoulders 84 include an inclined ramp surface facing the rear of the secondary lock 60 and a perpendicular locking shoulder section facing the outer or mating face of the secondary lock.
  • the external shoulder 88 is located between the internal shoulders 84 and the mating face of the secondary lock 60.
  • Outershoulder 88 is centrally positioned with channel 82 laterally between the two spaced apart ridges 86a and 86b as shown in Figure 20.
  • each finger 85 cannot be shifted past the corresponding strap 80 into the closed position without first depressing each finger 85, the secondary lock 60 cannot be inadvertently shifted from the position of the secondary lock shown in Figure 6 in which the subassembly is shipped.
  • the secondary lock 60 is shifted to the second position in Figure 8
  • the lock and shoulder 85a is cammed outwardly over an inclined ramp surface on the external shoulder 88.
  • the latching finger 85a is free to return to its normal position and the shoulder 85a will engage the locking surface on the outer face of external shoulder 88 to firmly secure the secondary lock 60 to the insulative housing 30.
  • the outer shroud surrounding the rows of latches 50 limits outward deflection of latches 50 adjacent this outer wall or shroud.
  • outwardly deflected latches 50 adjacent the outer shroud such as the latch shown in Figure 6, will not be broken when a force is applied to the secondary lock 60 in an attempt to shift the secondary lock from the first position shown in Figures 6 and 7 to the second position shown in Figure 8. Since there are a plurality of rows of latches 50, the inner latches will not abut the outer wall. Protrusions 51 on the inner face of the secondary lock 60 provide a stop to limit deflection of inner latches.
  • Cap 90 is received within the shroud 42 at the rear of insulative housing 30.
  • Cap 90 comprises both a seal cap used in conjunction with conductor seal 110 and a latching mechanism for securing connector 6 to a mating connector such as pin header 8.
  • Cap 90 has a plurality of snaps 91 engagable with protrusions 43 on the exterior of shroud 42 to secure the cap 90 to the insulative housing 30 and to secure the conductor seal 110 within the insulative housing shroud 42.
  • Cap 90 also has a connector latch 92 extending forwardly from its upper edge and protruding beyond the shroud 42 for securing the electrical connector 6 to mating header 8. By positioning this connector latch 92 on the cap 90, the insulative housing 30 can be more easily manipulated by automated equipment since the latch would not be in the way.
  • the elastomeric seal 110 used to establish sealing integrity around individual conductors or wires 4 comprises a single piece family seal formed of a conventional elastomeric material. Seal 110 has a plurality of holes 114, each hole being dimensioned to receive a wire and to establish sealing integrity with that wire. Seal 110 also has peripheral sealing ribs 112 for establishing sealing integrity with the interior surface of the shroud 42. Seal 110 comprises a conventional family seal for establishing sealing integrity with a plurality of individual conductors. Seal 110 is positioned within shroud 42, and each individual hole 114 will be aligned with an opening or cavity 36 in the insulative housing 30 and with a pocket 62 in the secondary lock 60.
  • Seal cap 90 comprises a programmable plate. Programmable plate has a plurality of selectively removable projections 94 extending from one surface. These projections 94 are dimensioned for seating within a corresponding hole 114 on elastomeric seal 110.
  • Cap 90 can be manufactured of a conventional plastic material with projections 94 located in a pattern corresponding to the array of terminal positions or corresponding to the array of holes 114 in the seal 110. Only selected or arbitrary terminal positions might be needed in certain applications of this sealed electrical connector assembly 2.
  • Projections 94 can be removed from the seal cap programming plate only in those positions where a terminal is to be located. The remaining projections 94 can then extend through corresponding holes 114 in the elastomeric sealing member 110 thus providing closing holes 114 where no terminated wire is located.
  • seal cap 90 has a plurality of indentations 96 aligned with projections 94 on the opposite side of the plate. Selective projections can be removed by punching out the material in the corresponding indentation 96 using a suitable punching tool 160 in the manner shown in Figure 17.

  • Pin header 8 includes a plurality of stamped and formed tubular or cylindrical pins 20. Each stamped and formed pin 20 has first and second tubular sections 24a and 24b. Each pin also has a third channel section 26 which in the preferred embodiment of this invention includes a right angle bend and a portion of channel 26b. Channel section 26 includes two spaced apart sections 26a and 26b. Section 26a is located adjacent the second or larger tubular section 24b. A flattened section 27 is located between the two channel shaped sections 26a and 26a. The first tubular section 24a has a tapered nose 28 formed in a conventional manner.
  • the stamped and formed pin 20 is formed from a flat metal blank 130.
  • Blank 130 has a first section 136a and a wider second section 136b from which the first and second tubular sections 24a and 24b respectively are formed. Since second section 136b is wider, the corresponding second tubular section 24b will have a larger outer diameter than the first tubular section 24a.
  • a plug 120 is located within the wider second tubular section 24b. Plug 120 establishes a metal to metal seal with the inner surface 22 of the tubular pin 20. Plug 120 is formed from a portion of the second tubular section 136b of the metal blank 130. Plug 120 is formed by partially shearing the plug from the center of the blank.
  • Plug 120 remains joined to the blank 130 by an integral tail 128.
  • the contour of the plug 120 around the tail 128 has substantially the same shape as the inner surface of the second tubular section 24b of the tubular pin 20.
  • the outer contour of plug 120 thus has generally circular edges 126 which merge with concave radius edges or surfaces 124a and 124b which form the contour of the integral tail 128.
  • Plug 120 is formed by bending the integral tail 128 upwardly and forming the wider section of the blank 136b around the integral plug 120.
  • a metal to metal seal is thus formed by crimping a stamped and formed cylindrical pin around the generally circular plug 120.

  • the plurality of pin stabilizing ribs 148 extend from the lower portion of the central header bulkhead 144 and have pin stabilizing ribs 148a and 148b located on opposed surfaces of pin stabilizing ribs 148.
  • the channel shaped section on the rear of pins 20 fit within these pin stabilizing rib shoulders 148a and 148b to precisely position the pins for insertion into holes in a printed circuit board on which the header 8 is mounted.
  • a plurality of keying ribs 150 are located on the inner surface of an outer header shroud 156 which forms the inner housing cavity 142 in which the receptacle connector 6 is inserted. These keying ribs 150 correspond to the profile of the support platforms 74 located on the secondary lock 60.
  • the receptacle connector 6 When secondary lock 60 is properly positioned in the second position on the receptacle insulative housing 30, the receptacle connector 6 can be inserted into cavity 142 with platforms 74 being received between keying ribs 150. It should be noted that by properly positioning keying ribs 150 and by properly dimensioning the platform 74, the same basic connector can be used in a keyed configuration. Note that it would be possible to provide breakaway keying ribs 150 and breakaway platform sections 74 so that the same connectors could be easily keyed to prevent mating by improperly keyed connectors.
  • the pin header housing 140 can be secured to a printed circuit board by the use of appropriate hold down members 154 of conventional construction.
  • the receptacle connector 6 is secured to the header 8 by the connector latch 92 which engages latch shoulders 158 located on the exterior of the inner shroud 156 adjacent the mating face of the pin header 8.
  • the components comprising the receptacle connector 6 can be assembled in a shipped configuration prior to insertion of wires 4 terminated to receptacle terminal 10.
  • the secondary lock 60 can be secured to the mating face of the insulative housing 30 in the first position by the two position retainer means.
  • Latch finger 85A would be in engagement with the internal shoulders 84 and would be positioned between the internal shoulder 84 and the external shoulder 88 in this first position.
  • Interfacial seal 100 would be positioned in surrounding relationship to the sidewalls 40 and the endwalls 38 of the connector prior to assembly of the secondary lock 60 to the mating face of the insulative housing 30.
  • the platforms 74 located on the exterior of the sidewalls 40 will serve to retain the interfacial seal 100 on the exterior of the housing 30.
  • Seal 110 can be inserted within housing shroud 42 and the cap 90 can be secured to the housing shroud.
  • the seal 110 and the cap 90 can be assembled to the insulative housing 30 at the time wires are inserted into the connector.
  • cap 90 can be assembled to the connector with the projections 94 closing off any unused holes 114 in the manner shown in Figure 6. Terminated wires can then be inserted through open holes 114. Latches 50 will be deflected outwardly during insertion of the terminals 10 in the manner shown in Figure 6.
  • latches 50 have not yet entered pocket 62, these latches are free to expand outwardly when the secondary lock is in the first position.
  • the engaging surfaces 58 on latches 50 are received within the waist section 16 in engagement with the barrel shoulder 15. In this configuration the terminals cannot be withdrawn from housing 30.
  • the secondary lock 60 is then free to move from the first position shown in Figure 7 to the second position shown in Figure 8.
  • the latches 50 are received within the pocket 62 and latches 50 are not free to expand. Note that if any terminal is not fully inserted, thus allowing engaging surfaces 58 to move into the smaller diameter waist section 16 of the terminals 10, the secondary lock cannot be moved to the second position shown in Figure 8.
