Description

Technical Field

[0001] This application relates to the field of serial port card installation technology, and in particular to a drawer-type horizontal insertion serial port card tray. Background Technology

[0002] The primary purpose of a serial port card is to expand a computer's serial port interface, allowing the computer to communicate with various external devices. Serial communication can be used to control various devices, such as printers and cameras; or to connect various sensors and instruments. Through serial communication, data collected by sensors can be sent to a computer or other data processing equipment for processing and analysis. Currently, most existing serial port cards are vertically inserted. This layout is suitable for applications in taller chassis or equipment. However, in shorter chassis or certain specific chassis or equipment, vertical space is very limited, and no vertical arrangement space is reserved for expansion cards. To ensure that computer equipment has sufficient usable serial port interfaces, this application proposes a drawer-type horizontally inserted serial port card tray. Summary of the Invention

[0003] In view of this, this application proposes a drawer-type horizontal insertion serial port card tray.

[0004] According to one aspect of this application, a drawer-type horizontal insertion serial port card tray is provided, comprising: a base, a mounting plate, two or more reinforcing brackets, and a card extension bracket; The chassis is suitable for horizontal installation inside the equipment enclosure; The bottom of the mounting plate can be pulled out and set on the top of the chassis. There are two or more card insertion holes on the side wall of the mounting plate, and the two or more card insertion holes are arranged horizontally on the side wall of the mounting plate. The top of the mounting plate is suitable for installing serial port cards, and each serial port of the serial port card is respectively aligned with each card insertion hole so as to be exposed outward through the card insertion hole. The top surface of the mounting plate is provided with two or more reinforcing brackets, and each reinforcing bracket is located next to each card slot. The height adjustment bracket is set on the top surface of the chassis and adjacent to the mounting plate, and is used to fix the height adjustment bracket.

[0005] In one possible implementation, the mounting plate includes: a vertical plate and a base plate; The upright plate is set vertically on one side of the base plate, and two or more card insertion holes are opened on the upright plate.

[0006] In one possible implementation, the mounting plate has two push-pull handles.

[0007] In one possible implementation, there are four card slots.

[0008] In one possible implementation, the mounting plate further includes two connecting plates, with their sides connected to the upright plate and the base plate, respectively.

[0009] In one possible implementation, a positioning groove is provided on one side of the mounting plate connected to the chassis, and a positioning pin is provided on the top surface of the chassis, which allows the positioning pin to move in and out of the positioning groove when the mounting plate moves on the chassis.

[0010] In one possible implementation, the top surface of the mounting plate is provided with two or more support columns.

[0011] In one possible implementation, the top surface of the chassis is provided with a sliding limit frame, and the mounting plate can be pulled out and installed inside the sliding limit frame.

[0012] In one possible implementation, the sliding limit frame includes: a connecting plate and two limiting folding plates; the connecting plate is disposed on the top surface of the chassis, and the two limiting folding plates are respectively disposed on opposite sides of the top surface of the connecting plate.

[0013] In one possible implementation, fixed plates are provided on both sides of the top surface of the chassis.

[0014] Beneficial effects: The chassis allows the mounting plate to be placed horizontally inside a chassis or equipment enclosure. The top of the mounting plate is suitable for installing serial port cards, ensuring horizontal mounting within the enclosure. The horizontally arranged serial ports on the serial port card protrude outwards through horizontally arranged insertion holes, facilitating connection of external electronic devices. This application utilizes horizontally arranged insertion holes to horizontally mount the serial port card on the mounting plate, significantly saving vertical space and avoiding excessive vertical layout space. It is particularly suitable for chassis or equipment with height limitations, overcoming the rigid vertical space requirements of traditional vertical insertion cards and achieving efficient expansion within a compact layout. The drawer-style design allows users to easily pull out the mounting plate for installation, replacement, or maintenance of the serial port card, improving operational convenience, significantly reducing downtime, and increasing work efficiency.

[0023] Figure 1 This diagram illustrates the main structure of a drawer-type horizontal serial port card tray according to an embodiment of this application. Figure 1 As shown, a drawer-type horizontally inserted serial port card tray includes: a base 100, a mounting plate 200, two or more reinforcing brackets, and a pull-out card bracket 310; the base 100 is suitable for horizontal installation inside a device enclosure; the mounting plate 200 is removable and is located on the top surface of the base 100, and two or more card insertion holes 212 are provided on the side wall of the mounting plate 200, and the two or more card insertion holes 212 are arranged horizontally on the side wall of the mounting plate 200; the top of the mounting plate 200 is suitable for installing serial port cards, and each serial port 400 of the serial port card is respectively aligned with each card insertion hole 212 so as to be exposed outward through the card insertion hole 212; the pull-out card bracket 310 is located on the top surface of the base 100 and is adjacent to the mounting plate 200.

[0024] It should be noted that the chassis 100 is suitable for placing the mounting plate 200 horizontally inside the chassis or equipment enclosure. The mounting plate 200 is suitable for mounting a serial port card, which is then horizontally installed inside the chassis or equipment enclosure. The serial ports 400 arranged horizontally on the serial port card are exposed one by one through the horizontally arranged card insertion holes 212, which facilitates the connection of external electronic devices to the serial ports 400 through the card insertion holes 232. The chassis 100 is suitable for providing a mounting base for the mounting plate 200. Since the mounting plate 200 can be pulled out and moved on the chassis 100, when the chassis 100 is installed inside the equipment enclosure, the mounting plate 200 can move the serial port card above it in and out of the equipment enclosure. The reinforcing frame is suitable for strengthening the structural strength of the mounting plate 200 and the installation stability of the serial port card. This application utilizes horizontally arranged card slots 212 to allow the serial port card to be installed horizontally on the mounting plate 200, significantly saving vertical space and avoiding excessive vertical space occupation. This is particularly suitable for chassis or equipment with height constraints, overcoming the rigid vertical space requirements of traditional vertical card insertion, and achieving efficient expansion within a compact layout. The drawer-style design allows users to easily pull out the mounting plate 200 for the installation, replacement, or maintenance of the serial port card, improving operational convenience, significantly reducing downtime, and increasing work efficiency. The reinforced frame structure design significantly improves the installation stability of the serial port card, effectively preventing connection loosening due to vibration or displacement during equipment operation, ensuring a long-lasting and stable communication link, and enhancing the overall durability and performance of the system. This application has good compatibility, ensuring efficient expansion within limited space. It simplifies the installation process, reduces reliance on special chassis, reduces hardware investment costs, and simultaneously improves the flexibility and versatility of equipment deployment.

[0025] In one possible implementation, such as Figure 1 As shown, the mounting plate 200 includes a vertical plate 210 and a base plate 220. The vertical plate 210 is vertically disposed on one side of the base plate 220, and two or more insertion holes 212 are provided on the vertical plate 210. Furthermore, the main body of the vertical plate 210 is a rectangular plate structure, and the main body of the base plate 220 is a rectangular plate structure. The longitudinal side of the vertical plate 210 and the longitudinal side of the base plate 220 are fixedly connected by welding, and the vertical plate 210 and the base plate 220 are perpendicular to each other, so that when the base plate 220 moves on the chassis 100, the vertical plate 210 moves with the base plate 220.

[0026] In one possible implementation, the mounting plate 210 of the mounting disk 200 is provided with two push-pull handles 211. For example... Figure 2 As shown, two push-pull handles 211 are respectively located at the two top corners of the upright plate 210. The push-pull handles 211 are designed to improve the ease of pushing and pulling the mounting plate 200. Furthermore, the push-pull handles 211 are made of M3 expansion bolts for easy disassembly.

[0027] Furthermore, there are four card slots 212. Each card slot 212 has a rectangular hole structure. Figure 7 The RS-485 serial port card shown has four RS-485 serial ports 400 that are exposed through four card slots 212.

[0028] In one possible implementation, such as Figure 3 As shown, each reinforcing frame includes a first reinforcing member 600 and a second reinforcing member 610. The main body of the second reinforcing member 610 is a rectangular plate structure, and the second reinforcing member 610 has two screw holes 611. The second reinforcing member 610 is set on the top surface of the base plate 220 of the mounting plate 200. The first reinforcing member 600 is vertically set on the top surface of the second reinforcing member 610. The first reinforcing member 600 and the second reinforcing member 610 are fixed by welding. The main body of the first reinforcing member 600 has a folded plate structure with a 90° bend. One side of the first reinforcing member 600 is attached to the upright plate 210 and fixed to the upright plate 210 by welding. The other side of the first reinforcing member 600 is suitable for contacting the side wall of the serial port card to limit the position of the serial port card. It should also be noted that since the upright plate 210 of the mounting plate 200 has many openings, the overall strength is reduced. The setting of the reinforcing frame can increase the structural strength of the mounting plate 200.

[0029] Furthermore, the number of reinforcing brackets is the same as that of the card slots 212, both being four, with a reinforcing bracket provided on the side of each card slot 212. For example... Figure 7 As shown, an RS-485 serial port card is provided. The PCB board 410 of the serial port card has four recessed slots to make way for the reinforcement bracket, so that the PCB board 410 can be installed above the mounting plate 200 and the serial port 400 can be closely opposite the card slot 212.

[0030] In one possible implementation, the upright plate is also provided with multiple indicator light holes 213. The multiple indicator light holes 213 are arranged in an array next to the card slot 212. The indicator lights 430 on the serial port card are used to shine out through the indicator light holes 213 to display the transmit and receive status of the corresponding serial port.

[0031] Furthermore, there are a total of 32 indicator light holes 213, which are arranged in 4 rows and 8 columns.

[0032] In one possible implementation, the mounting plate 200 further includes two connecting plates 230, with their sides connected to the upright plate 210 and the base plate 220, respectively. Figure 3As shown, the connecting plate 230 is fixedly connected to the base plate 220 by welding on one side of its length. A folding plate 231 is provided on the side of the connecting plate 230 that connects to the upright plate 210. The folding plate 231 and the connecting plate 230 are bent at a 90° angle, and the folding plate 231 is fitted to the upright plate 210 and the two are fixedly connected by spot welding. The two connecting plates 230 are suitable for embedding into the limiting folding plate 520 of the sliding limiting frame, which not only improves the overall structural strength of the mounting plate 200 but also improves the smoothness of the mounting plate 200's pull-out mechanism.

[0033] In one possible implementation, the mounting plate 200 is provided with a positioning groove 221 on one side of the chassis 100, and the top surface of the chassis 100 is provided with a positioning pin 130, which is suitable for the positioning pin 130 to move in and out of the positioning groove 221 when the mounting plate 200 moves on the chassis 100.

[0034] Furthermore, the mounting plate has two positioning slots 221, and the chassis 100 is provided with two positioning pins 130.

[0035] Preferably, the main body of the positioning pin 130 is cylindrical with an outer diameter of 3mm. The positioning groove 221 corresponding to the base plate 220 of the mounting plate 200 is 3.1mm in size and the end of the groove is beveled to facilitate the sliding and alignment of the positioning pin 130, thereby ensuring the perfect fit between the serial port card and the pull-out card 300.

[0036] In one possible implementation, such as Figure 3 As shown, the base plate 220 of the mounting tray 200 has two or more support pillars 222. The support pillars 222 are used to support the PCB board 410 of the serial port card above, ensuring its stability. Furthermore, the main body of the support pillar 222 has an internally threaded pillar (rivet nut) structure. When the PCB board 410 of the serial port card is placed on the support pillar 222, screws are used to fix the PCB board 410 to the support pillar 222, ensuring that the PCB board 410 is securely mounted on the mounting tray 200 and preventing the PCB board 410 from falling off the mounting tray 200 due to instability during the pulling process. The same number of circular holes need to be made on the PCB board 410 corresponding to the positions and number of the support pillars 222.

[0037] Furthermore, there are a total of eight support columns 222, three of which are located away from the upright plate 210, and the remaining five are located close to the upright plate 210. The screws are preferably imperial #6-32 three-piece combination screws.

[0038] In one possible implementation, such as Figure 3As shown, the base plate 220 of the mounting disk 200 has two or more heat dissipation holes. The two or more heat dissipation holes are arranged in two rows and each heat dissipation hole has a rectangular hole structure to release the heat of the serial port card.

[0039] In one possible implementation, such as Figure 5 As shown, the main body of the chassis 100 is a rectangular plate structure. Vertical first fixing plates 110 are provided on both sides of the chassis 100's width. Each first fixing plate 110 has a protruding plate 112 on its top side, and two screw holes 111 are provided at both ends of each first fixing plate 110. Two second fixing plates 120 are provided on the side of the chassis 100 closest to the upright plate 210. Screw holes 121 are provided on the second fixing plates 120. The first fixing plates 110 and second fixing plates 120 are suitable for fixing the chassis 100 as a whole into the equipment housing by means of screw connection. The chassis 100 also has multiple screw holes 140 for direct connection to the equipment housing by means of screw connection.

[0040] In one possible implementation, the top surface of the chassis 100 is provided with a sliding limit bracket, within which the mounting plate 200 can be pulled out and positioned. It should be noted that the sliding limit bracket effectively secures the movement trajectory of the mounting plate 200, preventing accidental slippage or displacement during the pulling process, improving operational safety, and ensuring that users can easily push and pull the mounting plate 200 for quick access and maintenance. Furthermore, the sliding limit bracket has a simple structure and is easy to manufacture, reducing production costs.

[0041] In one possible implementation, the sliding limit frame includes: a connecting plate 500 and two limiting baffles 520; the connecting plate 500 is disposed on the top surface of the chassis 100, and the two limiting baffles 520 are respectively disposed opposite to each other on both sides of the top surface of the connecting plate 500. Figure 6 As shown, the main body of the connecting plate 500 is a Π-shaped plate structure. Multiple screw holes 510 are provided on the connecting plate 500 for fixing to the chassis 100 via screws. Limiting folding plates 520 are welded to both sides of the connecting plate 500. The limiting folding plates 520 have an L-shaped cross-section, and the two limiting folding plates 520 are arranged opposite each other with the opening sides of the L-shaped structure facing each other. Figure 1 As shown, the two sides of the mounting plate 200 are suitable for embedding into the inner side of the limiting folding plate 520. Under the limiting action of the limiting folding plate 520, the mounting plate 200 can only be pulled and moved horizontally on the chassis 100.

[0042] Preferably, the length, width and height of the sliding limit bracket are reserved with a gap of 0.3mm relative to the corresponding size of the mounting plate 200 to ensure smooth pulling of the mounting plate 200. The strict limitation of the left and right deviation of the mounting plate 200 is mainly achieved by the cooperation of the positioning pin 130 and the positioning groove 221 opened on the mounting plate 200.

[0043] In one possible implementation, such as Figure 2 As shown, the main body of the pull-up card bracket 310 is a rectangular shell structure. The pull-up card bracket 310 is vertically mounted on the top surface of the chassis 100, and the bottom of the pull-up card bracket 310 is fixedly connected to the chassis 100 by screws 314. Multiple heat dissipation holes 312 are provided on the side wall of the pull-up card bracket 310, and multiple internally threaded posts 313 for connecting rivets are also provided on the side wall of the pull-up card bracket 310. The pull-up card 300 is suitable for being fixed to the side of the pull-up card bracket 310 facing the mounting plate 200 by rivets. The PCB board 410 of the serial port card is inserted into the PCIE slot 320 of the pull-up card 300 to connect with other PCBs through the gold fingers of the pull-up card.

[0044] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments.
