Definitions

• the present invention relates to a shroud for fixing to one side of a panel about an aperture therethrough , to align and latchably engage a connector mated to a pin header fixed to the other side.
• a bulkhead connector is an electrical connector fixed to a panel or bulkhead which receives a mating connector through an aperture in the panel.
• a bulkhead connector is marketed by AMP Incorporated as its AMPMODU Feed-Through Pin Header
• the appropriate mating connector is an AMPMODU Shielded MT Receptacle Connector.
• a ground plane may be assembled between the bulkhead connector and the panel where it is desired to ground the shielding of the mating connector to the panel. When there is no positive means provided for aligning the mating connector with the aperture, it may be inserted somewhat skewed and misaligned with the pins , subjecting same to damage.
• the known bulkhead connector retains the mating connector solely by fingers of the ground plane engaging a recess in the shield of the mating connector. A shroud which could be fixed to the panel to provide alignment and positive engagement of the mating connector would be desirable.
• US-A-4,173 ,387 discloses a connector receiving shroud for fixing to a panel or the like , the shroud having an elongate through passage profiled to closely receive a connector therein for alignment with an array of contacts fixed relative to the panel. It is particularly adapted for fixing about a pin array in a printed circuit board and would not be well suited to panel and bulkhead connector application .
• a connector receiving shroud as described above is characterized in that the shroud comprises a first shroud member and a second shroud member , each member comprising an endwall and a pair of parallel sidewalls extending therefrom to define the passage.
• the sidewalls of the first member have means for latchably engaging the connector therebetween , the sidewalls of the first member each having an extension extending freely from said endwall opposite said passage.
• the endwall acts as a fulcrum whereby moving the extensions together moves the sidewalls apart as cantilevers.
• the inventive shroud is particularly suited for fixing about an elongate aperture in a panel , the passage providing access to a pin array in a header fixed to the other side of the panel .
• US-A-3 ,685 ,001 discloses a module support for fixing to a circuit board , the support comprising two members fitted to opposite ends of a module fixed to the board.
• the members each have an endwall and parallel sidewalls defining a passage, and are suitable for accommodating different size modules . However, it is not directed to latchably engaging a connector.
• FIGURE 1 is a perspective of the mating connector exploded from the assembled shroud
• FIGURE 2 is an exploded perspective of the shroud , panel , pin header , and mating connector
• FIGURE 3 is a plan view of the shroud members on the panel
• FIGURE 4 is a side view of the shroud members on the panel ;
• FIGURE 5 is an end view of the first shroud member;
• FIGURE 6 is an end view of the second shroud member.
• the shroud comprises a first shroud member 32 and a second shroud member 50 , shown assembled to panel 14 to collectively define an elongate entry profiled to closely receive a mating connector 24.
• the first member 32 has an endwall 34 having a pair of parallel sidewalls 36 extending therefrom .
• Each sidewall 36 has an extension 40 extending freely from the opposite side of the endwall 34, which acts as a fulcrum when the extensions 40 are squeezed together so that sidewalls 36 move apart.
• a pedestal 42 extends from endwall 34 opposite sidewalls 36 for mounting flushly against panel 14.
• a stop 46 upstanding from the pedestal 42 prevents overstressing extensions 40.
• the second member 50 likewise has an endwall 52 with parallel sidewalls 54, but respective extensions 58 are offset from sidewalls 54 and integral with pedestal 60 to inhibit outward movement of sidewalls 54.
• the connector 24 has a stamped and formed metal shield 26 which is stamped with latching recesses 28 which are engaged by latches 37 on sidewalls 36 , which recesses also serve to retain a snap-on polarization block 29.
• the shroud thus provides aligning , latching , and polarizing means for a connector 24 received in bulkhead connector or feed-through pin header 2 fixed to the opposite side of panel 14.
• the pin header 2 comprises a dielectric housing 3 having a cavity 4 with an array of pins 5 therein .
• a typical header 2 has two rows of pins 5 on .100 in . centers; headers are available in a variety of sizes with up to thirty pins per row .
• the header 2 has holes 6 which align with holes 18 in panel 14 as cavity 4 is aligned with aperture 16 in the panel .
• a stamped and formed metal ground plane 8 is interposed between the header 2 and panel 14; the ground plane 8 has an aperture 9 flanked by resilient fingers 10 which extend into cavity 4.
• the panel 14 receives header 2 and ground plane 8 against one surface thereof and members 32 , 50 against the other surface.
• Bolts 20 received through holes in the respective components serve to retain them together as a unit to receive mating connector 24.
• the metal shield 26 has an elongate stamped recess 27 in each opposed surface thereof, which recesses 27 are engaged by resilient fingers 10 when connector 24 is received in cavity 16.
• Figure 3 shows the shroud members 32 , 50 as bolted through respective pedestals 42 , 60 to panel 14.
• the endwalls 34 , 52 and sidewalls 36 , 54 closely flank the aperture 16 so that a mating connector 14 ( Figure 1 ) received therein will be correctly aligned with the pins 5.
• the latches 37 overhang aperture 16 and interfere with reception of connector 24 to urge the sidewalls 36 apart until recesses 28 are engaged.
• Figure 4 is a side view of the members 32 , 50 positioned against panel 14 to header 2.
• the sidewalls 36 have standoffs 38 which abut panel 14 to prevent deflection theretoward during insertion of connector 24, and the sidewalls 54 have standoffs 56 which abut panel 14 for stability.
• Figure 5 shows the studs 45 which extend downward from pedestal 42 and are aligned for reception in holes 19 , which assures proper alignment of first member 32 with panel 14. Note the ramped upper surfaces of latches 37, which serve to urge sidewalls 36 apart as mating connector 24 ( Figure 1 ) is received .
• Figure 6 shows the studs 63 which extend downward from pedestal 60 to align second member 50 with panel 14.
