DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
As required, a detailed illustrative embodiment of the present connector isolator is disclosed herein. However, techniques, systems and operating structures in accordance with the present connector isolator may be embodied in a wide variety of forms and modes, some of which may be quite different from those in the disclosed embodiment. Consequently, the specific structural and functional details disclosed herein are merely representative, yet in that regard, they are deemed to afford the best embodiment for purposes of disclosure and to provide a basis for the claims herein which define the scope of the present connector isolator. The following presents a detailed description of an illustrative embodiment (as well as some alternative embodiments) of the present connector isolator.
In the Figures, like numerals indicate like elements.
FIG. 1 shows a portable computer or other portable computing device 1 seated in a docking tray 3 of a docking station 5. Such portable computing devices 1 are generally provided with one or more connectors and ports for function expansion, usually on the rear face of its casing which supports its display unit 7. These portable computing devices 1 are furnished with additional functions by connecting peripheral devices, such as a hard disk drive, mouse, printer, etc., to the connectors and ports.
FIG. 2 shows the backside of docking tray 3 which includes a mounting structure 9 that is structured to adapt docking station 5 for mounting to an external support structure, by example and without limitation, a universally positionable device invented by the inventor of the present invention as disclosed in U.S. Pat. No. 5,845,885, which is incorporated herein by reference. By example and without limitation, mounting structure 9 is provided as a plurality of mounting holes 11 projected from a bottom plane 13. Other mounting structures 9 are also contemplated and may be substituted without departing from the spirit and scope of the invention.
Docking station 5 includes an expansion module 15, for example, integrated with mounting structure 9. Expansion module 15 includes, for example, a power adaptor port 17 for connecting an external power supply and a data input/output (I/O) port 19 such as a Universal Serial Bus (USB) port or other data transfer port.
FIG. 3 and FIG. 4 are different cross-section views of docking station 5 wherein docking tray 3 is formed with a device bearing plate 21 having external bearing surface 23 where portable computing device 1 is seated, and an opposite interface surface 25 where expansion module 15 is mounted. Portable computing device 1 includes an expansion connector port 27 for function expansion. Expansion connector port 27 is structured to receive an electrical expansion connector 29 that is provided at bearing surface 23. For example, electrical expansion connector 29 is projected through an aperture 31 formed through bearing plate 21 between its external bearing surface 23 and opposing interface surface 25. Aperture 31 is sized to permit expansion connector 29 to move laterally in the plane of bearing plate 21 to reposition sufficiently to mate with expansion connector port 27 when portable computing device 1 is seated in docking tray 3.
Expansion connector 29 is fixedly mounted on a rigid connector carrier member 33 such as a printed circuit board (connector carrier PCB). Expansion module 15 may also include an expansion printed circuit board 35 (expansion PCB) in electrical communication with connector carrier member 33, or in direct communication with expansion connector 29, for example, through a flexible ribbon cable 37 extended therebetween.
Expansion module 15 includes a connector isolator system having both one or more in-plane isolators 39 that isolate against lateral motion in the X-Y plane of connector carrier member 33, and one or more out-of-plane Z-axis isolators 41 that isolate against out-of-plane motion along the Z-axis perpendicular to the X-Y plane, i.e., along the direction of insertion of expansion connector 29 into expansion connector port 27 of computing device 1. In-plane isolators 39 permit lateral motion in the X-Y plane of connector carrier member 33 within a limited range for mating expansion connector 29 with expansion connector port 27 of portable computing device 1. However, in-plane isolators 39 permit expansion connector 29 to remain in constant electrical connection with expansion connector port 27 only during application of lateral shock and vibration loads in the X-Y plane that cause responsive in-plane motion of computing device 1 within docking tray 3 such that communication is uninterrupted between computing device 1 and expansion PCB 35.
Unfortunately, in-plane isolators 39 only respond to lateral X-Y in-plane motion of connector carrier member 33 and expansion connector 29 fixedly mounted thereon. X-Y in-plane isolators 39 cannot respond to out-of-plane Z-axis motion of computing device 1 within docking tray 3. Rather, shock or vibration inputs that cause out-of-plane separation of computing device 1 from docking tray 3, even within a limited range, can also cause momentary separation of expansion connector 29 from expansion connector port 27 of portable computing device 1. Therefore, one or more out-of-plane Z-axis isolators 41 couple connector carrier member 33, which supports expansion connector 29, to bearing plate 21 of docking tray 3. By example and without limitation, out-of-plane Z-axis isolators 41 include a rigid backstop 43 that is spaced a fixed offset distance 45 away from an interface surface by a spacer 47. Connector carrier member 33, having one or more in-plane isolators 39, is movably positioned between backstop 43 and interface surface 25 of bearing plate 21 so as to be movable out-of-plane, i.e., along the Z-axis. One or more biasing members 49, by example and without limitation coil compression springs (shown), resiliently urge connector carrier member 33 out-of-plane along the Z-axis toward bearing plate 21 of docking tray 3, whereby expansion connector 29 is positively urged toward computing device 1 and into constant engagement with expansion connector port 27, even when shock or vibration inputs cause out-of-plane separation of computing device 1 from bearing plate 21 of docking tray 3.
FIG. 5 shows details of out-of-plane Z-axis isolators 41 wherein connector carrier member 33 is displaced along Z-axis away from interface surface 25 of bearing plate 21 (shown in phantom) toward backstop 43, as when portable computing device 1 is flush against bearing surface 23 of bearing plate 21. For example, connector carrier member 33 is movable within a constant engagement range 51 between backstop 43 and interface surface 25 of bearing plate 21. Constant engagement range 51 is sized to ensure constant engagement of electrical connector 29 with expansion connector port 27 of portable computing device 1 during out-of-plane Z-axis motion of computing device 1 within docking tray 3 due to normal shock or vibration inputs that cause out-of-plane separation of computing device 1 from docking tray 3. For example, constant engagement range 51 is, but not limited to, about 0.060 inch for the present application, wherein shock and vibration regimens result in out-of-plane separation of about 0.040 inch of computing device 1 from docking tray 3, whereby out-of-plane separation cannot exceed constant engagement range 51 of out-of-plane Z-axis isolators 41. According to one embodiment, connector carrier member 33 is coupled to bearing plate 21 of docking tray 3 by threaded fasteners or other retainers 53 joined to bearing plate 21 through spacers 47, and constant engagement range 51 is set by the length of spacers 47. When portable computing device 1 is seated on external bearing surface 23 of docking tray 3 with expansion connector port 27 mated with expansion connector 29 through aperture 31, biasing members 49 are compressed along Z-axis into respective sockets or other receivers 55 formed in backstop 43. Simultaneously, in-plane isolators 39 slide along length of respective spacers 47 for at least a portion of constant engagement range 51 or until bottoming out against backstop 43, and connector carrier member 33 is forced against expansion of biasing members 49 away from interface surface 25 of bearing plate 21.
FIG. 6 shows details of out-of-plane Z-axis isolators 41 wherein connector carrier member 33 is displaced along Z-axis away from backstop 43 toward interface surface 25 bearing plate 21 (shown in phantom), as when shock or vibration inputs cause out-of-plane separation of computing device 1 away from bearing surface 23 of bearing plate 21. Here, biasing members 49 are expanded along Z-axis between backstop 43 and interface surface 25 of bearing plate 21. Simultaneously, in-plane isolators 39 slide along length of respective spacers 47 for at least a portion of constant engagement range 51 or until bottoming out against interface surface 25 of bearing plate 21, and connector carrier member 33 is forced by expansion of biasing members 49 away from backstop 43 and toward interface surface 25 of bearing plate 21. Accordingly, expansion connector 29 is projected through aperture 31 to remain in mated connection with expansion connector port 27 of computing device 1.
Here, in-plane isolators 39 are elastomeric bushings having a central tube 57 fit through an aperture 59 through connector carrier member 33, and upper and lower flanges or lips 61, 63 positioned on opposites of connector carrier member 33. A plurality of elastomeric isolation spokes 65 are projected radially inwardly of central tube 57. Spacers 47 are slidingly received through isolator tube 57 between isolation spokes 65. During initial seating of computing device 1, isolation spokes 65 bend radially under lateral X-Y in-plane pressure of spacers 47 to lateral X-Y in-plane motion of connector carrier member 33 to accommodate mating of expansion connector 29 with expansion connector port 27 of portable computing device 1. When docking station 5 is subjected to lateral shock and vibration loads in the X-Y plane, isolation spokes 65 bend radially to permit limited lateral X-Y in-plane motion of connector carrier member 33 to maintain constant lateral engagement of expansion connector 29 with expansion connector port 27. However, as disclosed herein, X-Y in-plane isolators 39 cannot respond to out-of-plane Z-axis motion of computing device 1 within docking tray 3, such that shock and/or vibration inputs having an out-of-plane Z-axis component potentially interrupt communication between expansion PCB 35 and computing device 1.
FIG. 7 shows expansion connector 29 mounted on connector carrier member 33 with in-plane isolators 39.
FIG. 8 shows connector carrier member 33 opposite from expansion connector 29 and having in-plane isolators 39 with footprint of expansion connector 29 (shown in phantom). Biasing members 49 of two or more out-of-plane Z-axis isolators 41 are positioned on connector carrier 33 between a triangular plurality of X-Y in-plane lateral shock and vibration isolators 39. For example, as shown here, biasing members 49 are positioned opposite from expansion connector 29, and substantially aligned with end portions 29a, 29b thereof (shown in FIG. 7).
FIG. 9 illustrates connector carrier member 33 positioned on bearing plate 21 of docking tray 3 with X-Y in-plane lateral shock and vibration isolators 39 slidingly installed over a triangular arrangement of spacers 47 projected from interface surface 25 of bearing plate 21. Connector carrier member 33 is thus slidingly suspended between backstop 43 and interface surface 25 of bearing plate 21. Accordingly, connector carrier member 33 is slidably movable out-of-plane, i.e., along the Z-axis, by lateral shock and vibration isolators 39 sliding along respective spacers 47. Backstop 43 is shown removed here to show biasing members 49.
FIG. 10 illustrates connector carrier member 33 sandwiched between interface surface 25 of bearing plate 21 and backstop 43. As disclosed herein, biasing members 49 are captured between connector carrier member 33 and backstop 43 for resiliently urging connector carrier member 33 out-of-plane along the Z-axis toward bearing plate 21 of docking tray 3.
FIG. 11 and FIG. 12 both illustrate connector carrier member 33 operated in combination with out-of-plane Z-axis isolators 41. In both FIG. 11 and FIG. 12, portable computing device 1 is positioned on bearing plate 21 of docking tray 3. Furthermore, expansion connector 29 is constantly mated with expansion connector port 27 of portable computing device 1.
In FIG. 11, portable computing device 1 is seated substantially flush against external bearing surface 23 of bearing plate 21. Accordingly, expansion connector port 27 of computing device 1 is positioned adjacent to aperture 31 in bearing plate 21. Connector carrier member 33 is displaced away from bearing plate 21 and toward spaced-away backstop 43 by mating of expansion connector 29 with expansion connector port 27 of portable computing device 1. When computing device 1 is seated substantially flush against external bearing surface 23 of bearing plate 21, displacement of connector carrier member 33 toward backstop 43 compresses biasing members 49 into sockets 55 or otherwise against backstop 43, while retainers 53 fix backstop 43 against spacers 47 of out-of-plane Z-axis isolators 41 at fixed offset distance 45 from bearing plate 21. Connector carrier member 33 is thus under constant pressure of compressed biasing members 49 to push expansion connector 29 into mating contact with expansion connector port 27 of portable computing device 1.
In FIG. 12, portable computing device 1 is lifted away from external bearing surface 23 of bearing plate 21, as by application of shock and/or vibration inputs having an out-of-plane Z-axis component. In response to portable computing device 1 being lifted away from external bearing surface 23 of bearing plate 21, out-of-plane Z-axis isolators 41 automatically operate to responsively urge expansion connector 29 into mating contact with expansion connector port 27 of portable computing device 1.
Here, compressed biasing members 49 automatically operate between bearing plate 21 and backstop 43 by expanding to displace connector carrier member 33 along spacers 47 toward interface surface 25 of bearing plate 21. Expanding biasing members 49 in turn pushes expansion connector 29 into maintaining constant mating contact with expansion connector port 27 of portable computing device 1. Therefore, out-of-plane Z-axis isolators 41 automatically maintain expansion connector 29 in maintaining constant mating contact with expansion connector port 27 of portable computing device 1 within constant engagement range 51 of connector carrier member 33, as disclosed herein.
Alternative Embodiment
FIGS. 13-16 all illustrate a single alternative embodiment of the connector isolator system of the invention, wherein FIG. 13 is a top pictorial view of the alternative embodiment of the connector isolator system, FIG. 14 is a front elevation view of the alternative embodiment of the connector carrier member shown in FIG. 13, FIG. 15 is a side cross-section view thereof, and FIG. 16 is a front cross-section view thereof.
According to this alternative embodiment of the connector isolator system of the invention, expansion connector 29 is fixedly mounted on rigid connector carrier member 33 such as a printed circuit board (connector carrier PCB). Expansion module 15 may also include expansion printed circuit board 35 (expansion PCB) in electrical communication with connector carrier member 33, shown for example in FIG. 3. Connector carrier member 33 is moveably coupled to a mounting plate 70 with expansion connector 29 projected through an aperture 71 (shown in FIG. 15) formed through mounting plate 70 between its external contact surface 76 and opposing operational surface 72. For example, one or more in-plane X-Y isolators 39 and one or more out-of-plane Z-axis isolators 41 combine to suspend connector carrier member 33 above an operational surface 72 of mounting plate 70. In operation, expansion connector 29 is insert into expansion connector port 27 of computing device 1, as disclosed herein. Thereafter, mounting plate 70 is attached to interface surface 25 of device bearing plate 21 opposite of external bearing surface 23 where portable computing device 1 is seated, shown for example in FIGS. 3 and 4. For example, fasteners 73 are mounted through a plurality of apertures 75 for coupling a contact surface 76 of mounting plate 70 to interface surface 25 of device bearing plate 21, as shown for example in FIG. 16.
Here, the connector isolator system includes one or more in-plane X-Y isolators 39 that isolate against lateral motion in the X-Y plane of connector carrier member 33, and one or more out-of-plane Z-axis isolators 41 that isolate against out-of-plane motion along the Z-axis perpendicular to the X-Y plane, i.e., along the direction of insertion of expansion connector 29 into expansion connector port 27 of computing device 1. Here, also in-plane isolators 39 permit lateral motion in the X-Y plane of connector carrier member 33 within a limited range for mating expansion connector 29 with expansion connector port 27 of portable computing device 1. However, in-plane isolators 39 permit expansion connector 29 to remain in constant electrical connection with expansion connector port 27 only during application of lateral shock and vibration loads in the X-Y plane that cause responsive in-plane motion of computing device 1 within docking tray 3 such that uninterrupted communication is maintained between computing device 1 and expansion PCB 35.
As disclosed herein, in-plane isolators 39 unfortunately only respond to lateral X-Y in-plane motion of connector carrier member 33 and expansion connector 29 fixedly mounted thereon. X-Y in-plane isolators 39 cannot respond to out-of-plane Z-axis motion of computing device 1 within docking tray 3. Rather, shock or vibration inputs that cause out-of-plane separation of computing device 1 from docking tray 3, even within a limited range, can also cause momentary separation of expansion connector 29 from expansion connector port 27 of portable computing device 1. Therefore, one or more out-of-plane Z-axis isolators 41 couple connector carrier member 33, which supports expansion connector 29, to bearing plate 21 of docking tray 3. By example and without limitation, out-of-plane Z-axis isolators 41 each include a rigid backstop 77 that is spaced a maximum offset distance 79 away from contact surface 76 of mounting plate 70, and in operation interface surface 25 of device bearing plate 21, by a spacer post 81. For example, spacer posts 81 is a shoulder screw threaded into a boss 83 formed on operational surface 72 of mounting plate 70, whereby maximum offset distance 79 spacing of backstop 77 away from contact surface 76 is adjustable by threading screw-type spacer posts 81 into or out of boss 83. Connector carrier member 33 is movably positioned by one or more in-plane isolators 39 between backstop 77 and operational surface 72 of mounting plate 70 so as to be movable out-of-plane, i.e., along the Z-axis. One or more biasing members 85, by example and without limitation coil compression springs (shown), is positioned between connector carrier member 33 and backstops 77 for resiliently urge connector carrier member 33 out-of-plane along the Z-axis toward bearing plate 21 of docking tray 3, whereby expansion connector 29 is positively urged toward computing device 1 and into constant engagement with expansion connector port 27, even when shock or vibration inputs cause out-of-plane separation of computing device 1 from bearing plate 21 of docking tray 3.
FIG. 13 shows a plurality of out-of-plane Z-axis isolators 41 positioned surrounding and balancing expansion connector 29. For example, four out-of-plane Z-axis isolators 41 are illustrated at the four corners of expansion connector 29. Alternatively, three out-of-plane Z-axis isolators 41 are positioned in a triangular pattern balancing expansion connector 29.
FIG. 13 also shows two of in-plane isolators 39 positioned adjacent to opposite ends of expansion connector 29. Alternatively, three X-Y in-plane lateral shock and vibration isolators 39 are positioned in a triangular arrangement around expansion connector 29, as disclosed in FIG. 8.
Spacer hubs 87 around the base of in-plane isolators 39 support connector carrier member 33 a fixed minimum offset distance 89 away from contact surface 76 of mounting plate 70.
In-plane isolators 39 are each slidably supported on spacers 47 which, by example and without limitation, are configured as guide posts that are extended from the center of one of spacer hubs 87. However, this arrangement of guide posts 47 with spacer hubs 87 is only for convenience of manufacture and is not critical to the practice of the invention.
As disclosed herein, in-plane isolators 39 are elastomeric bushings having a central tube 57 fit through an aperture 59 through connector carrier member 33, and upper and lower flanges or lips 61, 63 positioned on opposites of connector carrier member 33. A plurality of elastomeric isolation spokes 65 are projected radially inwardly of central tube 57. Guide posts 47 are slidingly received through isolator tube 57 between isolation spokes 65. During initial seating of computing device 1, isolation spokes 65 bend radially under lateral X-Y in-plane pressure of guide posts 47 to lateral X-Y in-plane motion of connector carrier member 33 to accommodate mating of expansion connector 29 with expansion connector port 27 of portable computing device 1. When docking station 5 is subjected to lateral shock and vibration loads in the X-Y plane, isolation spokes 65 bend radially against guide posts 47 to permit limited lateral X-Y in-plane motion of connector carrier member 33 for maintaining constant lateral engagement of expansion connector 29 with expansion connector port 27.
As disclosed herein, connector carrier member 33 is coupled to mounting plate 70 by guide posts 47, and is movable within constant engagement range 51 is the distance between maximum and minimum offset distances 79, 89 relative to contact surface 76 of mounting plate 70 as set by rigid backstops 77 and spacer hubs 87, respectively. When portable computing device 1 is seated on external bearing surface 23 of docking tray 3 with expansion connector port 27 mated with expansion connector 29 through aperture 31, biasing members 85 are compressed along Z-axis about respective spacer posts 81 extended from operational surface 72 of mounting plate 70. Simultaneously, in-plane isolators 39 slide along length of respective guide posts 47 for at least a portion of constant engagement range 51 or until bottoming out against backstops 77, and connector carrier member 33 is forced against expansion of biasing members 85 away from contact surface 76 of mounting plate 70 and interface surface 25 of bearing plate 21.
Optionally, constant engagement range 51 is adjustable by adjusting maximum offset distance 79 spacing of backstop 77 away from contact surface 76, as disclosed herein.
As illustrated in FIG. 16 (right side) connector carrier member 33 is optionally coupled to bearing plate 21 of docking tray 3 by threaded fasteners or other retainers 53 joined to mounting plate 70 through guide posts 47, and constant engagement range 51 is set by the length of guide posts 47. However, retainers 53 are optional and are not critical to the practice of the invention at least because coil spring biasing members 85 react against backstops 77 to urge connector carrier member 33 out-of-plane along the Z-axis toward operational surface 72 of mounting plate 70. Furthermore, reaction of biasing member 85 against backstops 77 effectively prevents overtravel of in-plane isolators 39 along guide posts 47 and disengagement of in-plane isolators 39 from guide posts 47. Additionally, the length of guide posts 47 can be adjusted to cooperate with a given biasing member 85 in combination with a given offset distance 79 of rigid backstop 77 away from contact surface 76 of mounting plate 70 to insure continuous engagement of in-plane isolators 39 with guide posts 47. Also, when spacer posts 81 is a shoulder screw threaded into a boss 83 formed on operational surface 72 of mounting plate 70, offset distance 79 of rigid backstop 77 away from contact surface 76 of mounting plate 70 is adjustable by advancing shoulder screw-type spacer posts 81 into engagement with mounting plate 70 thereby decreasing offset distance 79 or, in the alternative, backing shoulder screw-type spacer posts 81 away from engagement with mounting plate 70 thereby increasing offset distance 79.
While the preferred and additional alternative embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Therefore, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Accordingly, the inventor makes the following claims.
