Description

Technical Field

[0001] This utility model relates to a display card device, and more particularly to a display card device that can be plugged into two expansion slots simultaneously. Background Technology

[0002] Graphics cards are widely used on motherboards of desktop and laptop computers to expand functionality, thereby enhancing the computer's graphics processing power, computing power, and high-performance display capabilities. Due to the high-performance nature of graphics cards, they generate a significant amount of heat during operation, requiring heat dissipation. Therefore, most existing graphics cards are equipped with heatsinks to cool their circuit boards, ensuring that the operating temperature is kept within a certain range.

[0003] However, graphics cards with heatsinks tend to be larger and thicker. Therefore, when installed on a motherboard, their size and thickness will occupy more than two slots. Since existing graphics cards only have one mounting plate for insertion, the unused slots become essentially useless. Furthermore, with only a single mounting plate in the motherboard slot, the graphics card is prone to movement and may not be properly positioned, potentially causing damage or electrical connection failure.

[0004] In view of this, the inventors have devoted themselves to research and applied theoretical principles to address the shortcomings of the prior art, and have made every effort to solve the above-mentioned problems, which have become the inventors' improvement targets. Summary of the Invention

[0037] The detailed description and technical content of this utility model will be explained below with reference to the accompanying drawings. However, the drawings are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0038] Please refer to the following first. Figure 1 As shown, this utility model provides a graphics card device for installation on a motherboard A. Specifically, the motherboard A has a plurality of expansion slots A1 arranged in parallel and spaced intervals, and the graphics card device of this utility model can be simultaneously inserted into two adjacent expansion slots A1. In this embodiment, each expansion slot A1 is a PCIe x16 slot, but this invention is not limited thereto. Please refer to... Figures 1 to 5 As shown, the display card device of this utility model mainly includes a base 10, a circuit board 20, a second tongue plate 30, and a cable group 40.

[0039] In this embodiment, the base 10 has a rectangular structure, but the present invention is not limited thereto. The base 10 mainly includes a housing 11 and a heat dissipation assembly (not shown) disposed within the housing 11. The housing 11 of the base 10 has a first mounting side 111 and a second mounting side 112 opposite to each other, and a top side 113 and a plug-in side 114 opposite to each other. Specifically, the first mounting side 111 and the second mounting side 112 are located on the left and right sides of the housing 11, while the top side 113 and the plug-in side 114 are located on the top and bottom sides of the housing 11, respectively, but the present invention is not limited thereto. The heat dissipation assembly is used to dissipate heat and cool down the electronic components mounted on the first mounting side 111 or the second mounting side 112. The heat dissipation assembly can be a heat sink, a fan, a radiator, or a liquid cooling head, etc., and the present invention does not impose any restrictions on these.

[0040] The circuit board 20 is mounted on the housing 11 of the base 10. In this embodiment, the circuit board 20 is mounted on the first mounting side 111 of the housing 11, and the heat generated when it is powered on can be cooled by the heat dissipation components inside the housing 11. The circuit board 20 has a first tongue plate 21 corresponding to the plug-in side 114. Specifically, the first tongue plate 21 is located below the circuit board 20 and corresponds to the plug-in side 114 of the housing 11. In this embodiment, the first tongue plate 21 protrudes slightly from the plug-in side 114 of the housing 11, thereby facilitating insertion into the expansion slot A1 on the motherboard A, but this invention is not limited thereto.

[0041] The second tongue plate 30 is disposed on the housing 11 of the base 10, and the second tongue plate 30 is configured corresponding to the insertion side 114. Specifically, the second tongue plate 30 is disposed on the second mounting side 112 of the housing 11, and the second tongue plate 30 is adjacent to the bottom of the housing 11 and corresponds to the insertion side 114 of the housing 11. In this embodiment, the second tongue plate 30 protrudes slightly from the insertion side 114 of the housing 11, thereby facilitating insertion into the expansion slot A1 on the motherboard A, but the present invention is not limited thereto. The second tongue plate 30 and the first tongue plate 21 are arranged parallel to each other and spaced apart, so that they can be inserted into two adjacent expansion slots A1 respectively. In other words, the interval between the second tongue plate 30 and the first tongue plate 21 is the interval between any two adjacent expansion slots A1 on the motherboard A.

[0042] The two ends of the cable group 40 are electrically connected to the circuit board 20 and the second tongue plate 30, respectively. Therefore, the second tongue plate 30 can be electrically connected to the circuit board 20 through the cable group 40. Thus, when the display card device of this invention is installed on the motherboard A, the first tongue plate 21 and the second tongue plate 30 can be simultaneously inserted into two adjacent expansion slots A1 on the motherboard A, thereby significantly improving the transmission speed and achieving a positioning effect. Specifically, since the expansion slots A1 in this embodiment are all PCIe x16 slots, when the first tongue plate 21 and the second tongue plate 30 of the display card device of this invention are simultaneously inserted into two expansion slots A1, up to 32 bandwidth channels can be connected simultaneously, thus doubling the transmission speed.

[0043] Further explanation: In this embodiment, the cable assembly 40 mainly includes a third tongue plate 41 and multiple cables 42. However, this invention is not limited to this; for example, the cable assembly 40 may also include only multiple cables 42 directly electrically connected to the circuit board 20 and the third tongue plate 41. The third tongue plate 41 is disposed on the opposite side of the plug-in side 114, and the third tongue plate 41 is located between the circuit board 20 and each cable 42. Specifically, the third tongue plate 41 is disposed on the top side 113 of the housing 11 of the base 10, and the third tongue plate 41 is electrically connected to the circuit board 20. Each cable 42 is substantially located on the second mounting side 112 of the housing 11. In other words, the circuit board 20 and each cable 42 are respectively disposed on opposite sides of the base 10. The two ends of each cable 42 are respectively soldered to the second tongue plate 30 and the third tongue plate 41, so that the signal of the circuit board 20 can be transmitted to the third tongue plate 41 through the high-speed transmission of each cable 42.

[0044] Furthermore, to facilitate the connection of the third tongue plate 41 to the circuit board 20 and form an electrical connection, the cable assembly 40 in this embodiment also includes a connection port 43, and the circuit board 20 also has a fourth tongue plate 22. The connection port 43 is disposed on the third tongue plate 41. The fourth tongue plate 22 is located on the side of the circuit board 20 away from the first tongue plate 21, and the fourth tongue plate 22 is inserted into the connection port 43 and can form an electrical connection with the third tongue plate 41 through the cables 42. Thus, through the connection port 43 of the third tongue plate 41, the cable assembly 40 can be quickly disassembled or installed on the fourth tongue plate 22 of the circuit board 20.

[0045] In this embodiment, the display card device further includes at least one bolt 50 and at least one fastener 60. The bolt 50 passes through the third tongue plate 41 and is screwed to the housing 11 of the base 10, thereby fixing the third tongue plate 41 to the top side 113 of the housing 11. The fastener 60 passes through the second tongue plate 30 and is fixed to the housing 11 of the base 10, thereby fixing the second tongue plate 30 to the second mounting side 112 of the housing 11. The fastener 60 can be a screw, rivet, fastener, or locating pin, etc., and this invention does not impose many limitations on this. In this embodiment, there are two bolts 50 and two fasteners 60, which can stably fix the third tongue plate 41 and the second tongue plate 30 without causing them to shake or rotate. However, in other embodiments, the number of bolts 50 and fasteners 60 can be one or more.

[0046] Furthermore, in this embodiment, the housing 11 of the base 10 has a recess 115. Specifically, the recess 115 is located on the top side 113 and the second mounting side 112 of the housing 11. The cable assembly 40 is located within the recess 115, so it does not protrude from the outer surface of the housing 11. In other words, the third tongue 41 is accommodated within the recess 115 on the top side 113 of the housing 11, while each cable 42 is accommodated within the recess 115 on the second mounting side 112 of the housing 11. Thus, the size of the existing graphics card device can be maintained without affecting the internal heat dissipation components of the housing 11.

[0047] Further explanation: the base 10 also includes a cover 12 and a side cover 13. The cover 12 is disposed on the housing 11 and covers and shields the cable assembly 40. Specifically, the cover 12 is L-shaped, so it can simultaneously shield the third tongue plate 41 and each cable 42 located in the groove 115 on the top side 113 and the second mounting side 112 of the housing 11, thereby protecting the third tongue plate 41 and the cable assembly 40 and improving aesthetics. The side cover 13 is disposed on the housing 11 and covers the circuit board 20 located on the first mounting side 111, thereby protecting the circuit board 20 and improving aesthetics. In addition, in this embodiment, after the cover 12 and the side cover 13 are installed on the housing 11 of the base 10, both the cover 12 and the side cover 13 are substantially flush with the outer surfaces of the first mounting side 111 and the second mounting side 112 of the housing 11 and do not protrude, thereby ensuring that the thickness of the display card device does not increase.

[0048] The display card device of this utility model has a first tongue plate 21 on the circuit board 20, and a second tongue plate 30 is parallel to the first tongue plate 21 and spaced apart from it, and is electrically connected to it through the cable group 40. This allows the display card device of this utility model to simultaneously plug into two expansion slots A1, thereby greatly improving the transmission speed and achieving a positioning effect.

[0049] In summary, the foregoing disclosure of this utility model is intended to enable those skilled in the art to clearly understand the technical content of this utility model and implement it accordingly, and is not intended to limit the scope of patent protection of this utility model. In addition, this utility model may have other embodiments not listed. Without departing from the spirit and essence of this utility model, those skilled in the art should be able to devise various corresponding changes and modifications based on this utility model, but all such changes and modifications should fall within the scope of protection of the patent application filed for this utility model.
