Abstract
Description
- 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. In general, 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.
- Because of the above problems, composite plastic materials have been employed to form the connector housing. Since plastic is non-conductive, fillers were used to provide some degree of EMI shielding. Great difficulty was incurred, however, in creating a sufficiently homogenous mixture of filler to provide effective shielding. This was because molding processes do not allow the necessary even distribution and physical contact between filler particles for achieving the desired overall conductivity.
- An alternative to the composite plastic approach is shown in U.S. Patent No. 4,678,260. Here, a foraminous sleeve of metal or wire mesh is embedded in the molded plastic housing. A portion of the sleeve is exposed to provide contact with other conductive parts which lead to a ground plane.
- Difficulty with this approach is that sleeve openings or mesh size directly affect the frequency level of EMI that can be effectively attenuated. Such a restriction greatly limits the usefulness of the device.
- 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.
- In another aspect, 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.

- Fig. 1 is a fragmentary cross-sectional view showing the plug housing and receptacle shell assemblies of the invention connected together.
- Fig. 2 is a fragmentary cross-sectional view showing the assemblies of Fig. 1 separated from each other.
- Fig. 3 is a fragmentary cross-sectional view showing an alternative shielded cable connection to a modified receptacle shell assembly.
- Fig. 4 is a view similar to Fig. 3 showing a second alternative shielded cable connection.
- Fig. 5 is a fragmentary cross-sectional view showing a receptacle shell grounded to a panel.
- With particular reference to Figs. 1 and 2 of the drawings, the overall connector of the invention is shown by
reference 10. The connector is preferably tubular in shape and consists of aplug housing assembly 12 and ashell assembly 14. Both assemblies releasably interfit with each other and are secured together with a coupling member 16. The plug housing assembly consists of aplug insert 45 enclosed by aplug housing 13 and the shell assembly consists of ashell insert 28 enclosed by areceptacle shell 15. - The receptacle shell is defined by an
inner surface 17, anouter surface 18 with ainner end portion 19 and anouter end portion 20. The outer surface may include anouter flange 21 for use in attaching the shell to a cabinet panel or other grounded external support structure. It also includes one ormore bosses 22 for connection withlip 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.
- Located adjacent the shell inner surface is an electrically
conductive shell sleeve 24. The shell sleeve includes anouter part 25 proximateouter end portion 20 and extends inwardly to ashell joint part 26. The shell joint part extends beyond the end ofinner 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 sleevemain body 27 to facilitate securement by abutment withinsert rib member 29. - The
plug housing 13 is defined by anouter end 30, amidportion 31 and aninner end 32. It includes a pluginner surface 33 and anexterior surface 34. The exterior surface provides plug thread means 35 for engagement with corresponding means on coupling member 16. - Positioned adjacent plug
inner surface 33 is an electricallyconductive plug sleeve 40. The plug sleeve provides a generally uniform interior diameter for enclosingplug insert 45. It includes aforward section 42 which is proximateouter end 30 and extends inwardly to aplug joint section 44 proximate thehousing midportion 31. In the same manner as with the shell sleeve,forward section 42 may be threadably attached to plug sleevemain body 43. This provides a convenient means for securement ofplug insert 45 via abutment with insert rib 46. - When the plug housing and receptacle shell are connected, a joint is formed between the
shell joint part 26 andplug 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. - With reference to the joint shown in Figs. 1 and 2, the plug housing
inner surface 33 is offset radially outwardproximate midportion 31. This accommodates a similar offset inplug sleeve 40 and allows the plug joint section to have a diameter greater thanshell 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. - To help insure good electrical communication at the joint connection, 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 anannular recess 50 located outwardly from adjacent the joint connection and proximateinner 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 ofshell joint part 26 to prevent unwanted contamination of the assembled parts. - In a manner known in the art, the insert assemblies primarily comprise a plastic body containing pin or socket contacts for terminating wires from cables. As shown, shell insert 28 terminates
wires 54 which are in electrical communication withsocket contacts 56. Plug insert 45 terminateswires 55 which electrically communicate withpin contacts 57. The pin contacts engage the socket contacts providing electrical continuity through the connector. - If the wires are assembled within a grounded outer conductive sheath for EMI protection, the sheath must be electrically connected to the sleeves of the plug housing and receptacle shell. As shown in Fig. 3, braided
metal sheath 60 engages extended shell sleeveouter part 61. The sheath end overliesannular notch 62 and is secured therein by clamping means shown as shrinkband 64. An identical arrangement is used to secure a grounded conductive sheath aroundplug 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. - With reference to Fig. 4, individual wires are shown as being protected with electrically conductive sheathes 66. In this case, each sheath is terminated with an
insert part 67 which, in turn, engages corresponding openings in a ground plane shown asshell plate 68. The plate overlies the outer face ofshell insert 28 and is in electrical communication with extended shell sleeveouter part 61′. The shell plate is retained within the shell sleeve by leg projections 69 which frictionally engage corresponding grooves about the interior surface ofouter 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 integralradial flange 72 having an outerannular lip 73. The lip has anend face 74 that engages bulkhead panel 75 and provides electrical communication from the receptacle shell to the grounded panel. Optionally, the end face may include one or more scratch points 76 to help insure electrical contact with the panel. - In place of
outer flange 21, receptacle shell is modified to coact with the jam-nut connector by providing anouter retainer section 70. This section includes adistal flange 77 which is spaced fromlip 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 engagesthreads 80 and functions to secure the overall assembly to the bulkhead panel. - In addition to the above-described embodiment, it will be appreciated that other panel engagement means could be used. For example, 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.
- While the invention has been described with respect to a preferred embodiment, it will be apparent to those skilled in the art that various modifications and improvements may be made without departing from the scope and spirit of the invention. Accordingly, it is to be understood that the invention is not to be limited by the specific illustrative embodiments, but only by the scope of the appended claims.
