Definitions

  • the invention relates to electrical connectors and, more particularly, to EMI shielded connectors which include protection against harsh corrosive conditions.
  • Effective connectors should be mechanically strong, light weight, low cost, corrosion resistant and display high levels of EMI shielding.
  • good EMI shielding comes from metals.
  • Aluminum and its alloys have always been good choices because they are lightweight, highly conductive and readily machined into parts. Unfortunately, aluminum is also chemically reactive and is prone to significantly corrode in harsh environments.
  • the present invention provides an EMI shielded electrical connector for terminating EMI shielded wires, the connector comprising: a plug housing constructed of a dielectric material having an outer end, a midportion and an inner end, the housing including a plug inner surface and a plug exterior surface; an electrically conductive plug sleeve located adjacent the inner surface having a forward section extending from proximate the outer end to a plug joint section proximate the midportion; a receptacle shell constructed of dielectric material adapted for engagement with the plug housing having an outer end portion and an inner end portion with a shell inner surface and shell outer surface; and, an electrically conductive shell sleeve located adjacent the shell inner surface having an outer part extending from proximate the outer end portion to a shell joint part, the shell joint part and the plug joint section forming a joint connection at a location proximate the plug housing midportion when the plug housing and receptacle shell are engaged.
  • the present invention provides an electrical connector comprising a plastic receptacle shell releasably engaged with a plastic plug housing, the housing having an outer end, a midportion and an inner end, the receptacle shell having an outer end portion and an inner end portion, the housing and shell each enclosing an insert containing means for terminating one or more cables, the shell having an inner metallic shell sleeve that includes a shell joint part, the housing having an inner metallic plug sleeve with a plug joint section located proximate the midportion, the sleeves being engaged at a joint connection proximate the midportion.
  • the connector is preferably tubular in shape and consists of a plug housing assembly 12 and a shell assembly 14. Both assemblies releasably interfit with each other and are secured together with a coupling member 16.
  • the plug housing assembly consists of a plug insert 45 enclosed by a plug housing 13 and the shell assembly consists of a shell insert 28 enclosed by a receptacle shell 15.
  • the receptacle shell is defined by an inner surface 17, an outer surface 18 with a inner end portion 19 and an outer end portion 20.
  • the outer surface may include an outer flange 21 for use in attaching the shell to a cabinet panel or other grounded external support structure. It also includes one or more bosses 22 for connection with lip 23 of coupling member 16 for securing together the shell and plug assemblies.
  • the plug housing, receptacle shell and coupling member are constructed of a dielectric material such as plastic. This permits the use of low cost high volume manufacturing processes such as injection molding.
  • the shell sleeve Located adjacent the shell inner surface is an electrically conductive shell sleeve 24.
  • the shell sleeve includes an outer part 25 proximate outer end portion 20 and extends inwardly to a shell joint part 26.
  • the shell joint part extends beyond the end of inner end portion 19.
  • the shell sleeve is constructed of metal and provides a generally uniform interior diameter for enclosing shell insert 28. As shown, outer part 25 is threadably attached to the shell sleeve main body 27 to facilitate securement by abutment with insert rib member 29.
  • the plug housing 13 is defined by an outer end 30, a midportion 31 and an inner end 32. It includes a plug inner surface 33 and an exterior surface 34. The exterior surface provides plug thread means 35 for engagement with corresponding means on coupling member 16.
  • the plug sleeve 40 Positioned adjacent plug inner surface 33 is an electrically conductive plug sleeve 40.
  • the plug sleeve provides a generally uniform interior diameter for enclosing plug insert 45. It includes a forward section 42 which is proximate outer end 30 and extends inwardly to a plug joint section 44 proximate the housing midportion 31. In the same manner as with the shell sleeve, forward section 42 may be threadably attached to plug sleeve main body 43. This provides a convenient means for securement of plug insert 45 via abutment with insert rib 46.
  • a joint is formed between the shell joint part 26 and plug joint section 44. This provides electrical communication between the respective sleeves and shields the insert assemblies from EMI.
  • the joint connection shown in the drawings may be referenced as a lap joint, but other joint connections known in the art may be used such as bayonet, twist lock, threads and the like.
  • the plug housing inner surface 33 is offset radially outward proximate midportion 31. This accommodates a similar offset in plug sleeve 40 and allows the plug joint section to have a diameter greater than shell joint part 26. Note that the shell joint part extends axially from the sleeve main body with only a minor radially outward enlargement at its free end. As such, when the plug and receptacle assemblies are moved together, shown by arrows A in Fig. 2, the shell joint part will slide over and overlap the plug joint section.
  • a junction means may be used. This may comprise an electrically conductive ring member overlying at least a portion of the plug joint section. As shown, the ring member comprises a metallic spring washer 48 forming an annular interface between the plug joint section and shell joint part.
  • the plug housing inner surface 33 further includes an annular recess 50 located outwardly from adjacent the joint connection and proximate inner end 32.
  • the recess is adapted to accommodate a resilient environmental sealing member shown as O-ring 52.
  • the sealing member is sized to resiliently engage the outer surface of shell joint part 26 to prevent unwanted contamination of the assembled parts.
  • the insert assemblies primarily comprise a plastic body containing pin or socket contacts for terminating wires from cables.
  • shell insert 28 terminates wires 54 which are in electrical communication with socket contacts 56.
  • Plug insert 45 terminates wires 55 which electrically communicate with pin contacts 57. The pin contacts engage the socket contacts providing electrical continuity through the connector.
  • the sheath must be electrically connected to the sleeves of the plug housing and receptacle shell.
  • braided metal sheath 60 engages extended shell sleeve outer part 61.
  • the sheath end overlies annular notch 62 and is secured therein by clamping means shown as shrink band 64.
  • An identical arrangement is used to secure a grounded conductive sheath around plug wires 55 to an extended plug sleeve forward section (not shown).
  • Other sheath connection means may be used such as those shown in U.S. Patent Nos. 4,579,415 and 4,468,080 which are herein incorporated by reference.
  • each sheath is terminated with an insert part 67 which, in turn, engages corresponding openings in a ground plane shown as shell plate 68.
  • the plate overlies the outer face of shell insert 28 and is in electrical communication with extended shell sleeve outer part 61′.
  • the shell plate is retained within the shell sleeve by leg projections 69 which frictionally engage corresponding grooves about the interior surface of outer part 61′.
  • a plug face plate grounding plane identically arranged is utilized with the plug housing outer end. The contained face plates and sleeves provide continuous EMI shielding throughout the overall connector and wire connections.
  • Fig. 5 depicts grounding of the shell sleeve to an external support structure. This is accomplished with a grounding panel engagement means shown as jam-nut connector 71.
  • the connector is constructed of conductive material and includes an inner ring portion that directly engages the shell sleeve parts. Spaced outwardly is an integral radial flange 72 having an outer annular lip 73. The lip has an end face 74 that engages bulkhead panel 75 and provides electrical communication from the receptacle shell to the grounded panel.
  • the end face may include one or more scratch points 76 to help insure electrical contact with the panel.
  • receptacle shell is modified to coact with the jam-nut connector by providing an outer retainer section 70.
  • This section includes a distal flange 77 which is spaced from lip 73 to allow for placement of a panel O-ring seal 78.
  • the retainer section is plastic and generally overlies the metal jam-nut connector for environmental protection.
  • Jam-nut 79 engages threads 80 and functions to secure the overall assembly to the bulkhead panel.
  • panel engagement means could be used.
  • simple wires, conductive strips, metal plating on the shell receptacle exterior or conductors embedded within the molded shell receptacle could function to provide a grounding path from the shell sleeves.
