Title: Expansion card bracket mount panel

Description:
TECHNICAL FIELD 
     Example embodiments relate generally to the field of electronic component expansion cards and, more particularly, to expansion card bracket mount panels mounted to electronic component chassis&#39; and the insertion and removal of expansion cards to the expansion card bracket mount panels. 
     BACKGROUND 
     Demand for faster data transmission and increasing online payment gateway transactions have driven the use of hardware components such as Peripheral Component Interconnect Express (PCIe) cards. PCIe cards is a type of ‘expansion card’ that connects PCIe devices to a PCIe bus or host chipset, allowing for high bandwidth communication therebetween. PCIe cards can be, for example, video graphic cards, sound cards, small computer system interface (SCSI) cards, Redundant Array of Independent Disks (RAID) expansion cards, Universal Serial Bus (USB) port cards, and television tuner cards. 
     PCIe cards are typically inserted and retained into compatible slots of an electronic component system such as slots of a host, a server, a network switch, or a computer. Generally, dust covers (or ‘slot covers’) are first removed from a chassis of the electronic component system. Typically, the covers are attached to the chassis via a fixing screw. After the fixing screw is unscrewed, the dust cover is removed. Next, the PCIe card is aligned with the compatible slot, leveled, and gently but firmly inserted into the slot. Once the PCIe card is seated firmly in place, the fixing screw, previously removed from the chassis, is screwed back into the chassis, retaining a mounting portion of a PCIe card bracket of the PCIe card to the chassis, to prevent the PCIe card from inadvertently detaching from the slot. 
     Advanced Technology eXtended (ATX) motherboards of the computer, as an example, may have up to four (4) to six (6) slots for video graphic cards, WiFi cards, sound cards, and video capture cards. The four (4) to six (6) PCIe cards must be manually inserted into each slot, whereby each dust cover and screw must be individually extracted, each PCIe card must be individually inserted, and each screw must be individually screwed back to the chassis for retention of the PCIe card to the slot. 
     The manual extraction of each dust cover and screw and insertion of each PCIe card and screw, individually, is time consuming. The tool required for each extraction and insertion is inconvenient, for example, during sudden failure of the PCIe card and crash of the electronic component system when no tool may be available. Retention of the PCIe card to the chassis in the inside of the electronic component system is cumbersome, given the other electronic components therein, and manipulation of the screw which is small, which may be easily dropped, lost, or stuck in the components of the electronic component system. The wear and tear on the screw threads and/or chassis threads from the unscrewing and screwing of the dust covers and PCIe cards over time may cause failure thereto, such as stripped threading. By not being securely fixed to the slot due to the stripped threading, the PCIe card may inadvertently move, be detached and/or be damaged, causing the electronic component system to crash and fail.

FIG.  7    illustrates another cross-section view of the expansion card bracket mount panel of  FIGS.  5  and  8    in another moved position, according to disclosed embodiments.  FIG.  8    illustrates a cross-section view of the expansion card bracket mount panel of  FIG.  1   , according to disclosed embodiments. As illustrated in  FIGS.  5 - 8   , and as illustrated in  FIGS.  1 - 4   , the expansion card bracket mount panel  10  is configured to be mounted to the electronic component chassis  20  (partially shown) and for the at least one expansion card bracket  30  to be mounted thereto. The at least one expansion card bracket  30  may be a peripheral component interconnect (PCI) card, an accelerated graphics port (AGP) card, a PCI Express (PCIe) card, or any expansion card comprising a supporting base  32 , a mounting portion  36  and a circuit board  34 , which may be installed to, retained in, and extracted from an electronic component chassis  20 . The electronic component system, may be a host, a server, a network switch, a computer, or any electronic component system requiring installation, retention, and extraction of the at least one expansion card bracket  30  therein. 
     As illustrated in  FIG.  5   , when a user is installing the at least one expansion card bracket  30 , the latch component  200  is in the upward ready position  290 , perpendicular to the expansion card bracket frame  100 , and the retaining pressure component  300  is in the standby position  390 , a distance away and parallel to the expansion card bracket frame  100  and perpendicular to the latch component  200 . Operation of retaining the at least one expansion card bracket  30  to the electronic component system is from the exterior side  130  of the expansion card bracket frame  100 , and thus, exterior side of the electronic component chassis  20  of the electronic component system. When the latch component  200  is in the upward ready position  290  a frictional force is formed between the at least one position catch  910  and the at least one position latch  920 . A tension spring force is formed between the expansion card bracket frame  100  and the retaining pressure component  300 , whereby the tension spring is in an extended ready direction E 1 . The frictional force between the at least one position catch  910  and the at least one position latch  920  is greater than the spring force formed between the expansion card bracket frame  100  and the retaining pressure component  300 . The latch component  200  is steadily held in the upward ready position  290  and the retaining pressure component  300  is steadily held in the standby position  390 . 
     Next, a dust cover may be removed from the expansion card bracket mount panel  10 . Once the dust cover is removed, the at least one expansion card bracket  30  is aligned with a compatible slot (not shown), leveled, and gently but firmly inserted into the slot. When inserted into the slot, the at least one mount guide  700  protrudes through the guide slot  38  and the guide end  39  protrudes into the at least one expansion card bracket slot  22 . Following, the at least one expansion card bracket  30  is retained to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20  to prevent the at least one expansion card bracket  30  from inadvertently detaching from the slot. 
     As illustrated in  FIG.  6   , when the latch component  200  is rotated downward (A direction) toward the expansion card bracket frame  100  the frictional force between the at least one position catch  910  and the at least one position latch  920  is overcome and the spring force formed between the expansion card bracket frame  100  and the retaining pressure component  300  is lessened, whereby the tension spring moves in a retracted operational direction E 2  to drive the retaining pressure component  300  to rotate downward (B direction) and forward, angled to the expansion card bracket frame  100  and angled to the latch component  200 . As illustrated in  FIG.  7   , as the latch component  200  continues to rotate downward toward the expansion card bracket frame  100  the spring force formed between the expansion card bracket frame  100  and the retaining pressure component  300  increases, whereby the tension spring moves in an extended operational direction E 3 . The retaining pressure component  300  continues to rotate forward (C direction), decreasing an angle to the expansion card bracket frame  100  and decreasing an angle to the latch component  200 . As illustrated, elastic pressure contact component  320  of the retaining pressure component  300  begins to contact the bottom outer side  131  of the at least one expansion card bracket  30 . 
     As illustrated in  FIG.  8   , the at least one expansion card bracket  30  is retained to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20 , preventing the at least one expansion card bracket  30  from inadvertently detaching from the slot. It is noted that no tools, screws, or screwing is required for retention and disengagement of the at least one expansion card bracket  30  to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20 . It is also noted that retention and disengagement of the at least one expansion card bracket  30  to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20  occurs from the exterior side  130  of the expansion card bracket frame  100 , and thus, exterior side of the electronic component chassis  20  of the electronic component system. 
     When the latch component  200  continues to rotate downward (A direction) toward the expansion card bracket frame  100  to the latched position  230 , the spring force formed between the expansion card bracket frame  100  and the retaining pressure component  300  further increases, whereby the tension spring further moves in an extended operational direction E 4 . When the latch component  200  is in the latched position  230 , the latch component  200  is parallel to the expansion card bracket frame  100  and latched thereto. The retaining pressure component  300  continues to rotate forward (C direction), moving parallel to the expansion card bracket frame  100  and parallel to the latch component  200 . As illustrated, the retaining pressure component  300  is gradually forced to be encompassed within the latch component  200  via initial resistance between the pair of side catches  820  and the pair of side latches  810 . The retaining pressure component  300  is eventually encompassed within the latch component  200 . The at least one retaining latch  620  is latched to the at least one catch  610  and the pair of side latches  810  is latched to the pair of side catches  820 .

The elastic pressure contact component  320  eventually presses flush with the bottom outer side  131  of the at least one expansion card bracket  30 , whereby each arch of the elastic pressure contact component  32  corresponds to each of the at least one mount guide  700  of the bracket mount component  120 . 
     In the illustrated embodiments, when the latch component  200  is in the latched position  230  and the retaining pressure component  300  is in the retaining position  330 , a reaction force is formed between the elastic pressure contact component  320  and the bottom outer side  131  of the at least one expansion card bracket  30  upon deformation of the at least one expansion card bracket  30 . The reaction force is sufficient to retain the at least one expansion card bracket  30  to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20  to prevent the at least one expansion card bracket  30  from inadvertently detaching from the slot. 
     In the illustrated embodiments, when the latch component  200  is in the latched position  230  and the retaining pressure component  300  is in the retaining position  330 , a contact force is formed between the elastic pressure contact component  320  and the bottom outer side  131  of the at least one expansion card bracket  30 . The contact force is formed via the at least one retaining latch  620  being latched to the at least one catch  610  and the pair of side latches  810  being latched to the pair of side catches  820 .

As no tools, screws, or screwing is required for retention and disengagement of the at least one expansion card bracket  30  to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20 , time is saved as manual extraction of dust covers and screws and insertion of the expansion cards and screws, individually, is not required. Additionally, for example, during sudden failure of the expansion cards and crash of the electronic component system, no tool is required for extraction and insertion of the expansion cards, making extraction and insertion more convenient. Furthermore, as retention and disengagement of the at least one expansion card bracket  30  to the expansion card bracket mount panel  10  mounted to the electronic component chassis  20  occurs from the exterior side  130  of the expansion card bracket frame  100 , and thus, exterior side of the electronic component chassis  20  of the electronic component system, retention of the expansion cards to the electronic component chassis in the inside of the electronic component system is simplified as navigation with other electronic components is not required. Additionally, with no tools, screws, or screwing, manipulation of the screw which is small, which may be easily dropped, lost, or stuck in the components of the electronic component system is not required. The wear and tear on the screw threads and/or chassis threads from the unscrewing and screwing of the dust covers and expansion cards over time, causing failure thereto, such as stripped threading, resulting in the expansion cards being inadvertently moved, detached and/or damaged, causing the electronic component system to crash and fail is no longer a concern.
