Description

Technical Field

[0001] The utility model belongs to the technical field of computers, and in particular relates to an external graphics card expansion dock for a mini computer. Background Art

[0002] Mini computers are favored by consumers due to their small size and are sought after by computer players, especially game enthusiasts, competitive enthusiasts, and professional video producers. They expect to use higher-performance machines, but when a mini computer is running, the access speed between the processor (controller, calculator) and the memory is hundreds of millions of times per second, which will generate high temperatures on the narrow circuit board, which is not conducive to the performance of the machine. Since the processor is the hub of the entire computer system and must be soldered to the core part of the circuit board, in order to prevent the second graphics card from increasing the internal temperature of the computer and to meet the needs of high-performance players, the designer will place the second largest heat-generating device, the graphics card, outside the entire computer host, so as not to increase the temperature inside the host and to meet the needs of high-performance players.

[0004] A cover plate is fixed at the upper opening of the shell, and a placement plate is fixed at the bottom. The placement plate is used to stably place the graphics card expansion dock on the mini computer.

[0005] Preferably, the first side cover and the second side cover are fixed to the fastener slot located in the inner cavity of the shell by a first screw, which is used to fix the first side cover and the second side cover to the shell, and the first side cover also fixes the graphics card expansion dock to the mini computer by a second screw and a screw hole.

[0006] Preferably, the power interface and the Pcie socket are connected to the through opening at the bottom of the housing, and are used to connect the power supply terminal and the graphics card of the mini computer motherboard, and the connector is connected to the computer host circuit board for communication. Compared with the prior art, the beneficial effects of the utility model are as follows:

[0007] The expansion dock mentioned in the utility model can stably communicate and connect with the mini computer host. The second screw, screw hole and placement plate can physically fix the graphics card expansion dock and the mini computer. The power interface and Pcie socket further enhance the stability of the connection. The connector realizes high-speed data communication between the computer host and the external expansion graphics card. The expansion graphics card improves the operating performance of the host. The high temperature generated when the graphics card is working has no effect on the mini host. The power button can connect or disconnect the communication status between the expansion dock and the mini computer at any time, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
