Expansion card capable of being stably fixed

Abstract

The invention discloses an expansion card capable of being stably fixed. The expansion card comprises an expansion card body and a fastening member, wherein a plugboard is formed on a protruding part of a bottom edge of the expansion card body; the fastening member comprises a connecting board and a hook part; the hook part extends downwards from the bottom surface of the connecting board; and one side edge of the connecting board is fixed on the expansion card body to made the hook part correspond to the plugboard of the expansion card body in a spacing way. Accordingly, when the expansion card is inserted into a side wall to form a bayonet socket with an oblique angle block, the hook part of the fastening member can correspond to and be hooked with the oblique angle block, so that the plugboard is steadily inserted inside the bayonet socket and is difficult to separate from the bayonet socket under external forces, such as impact or vibration and the like.

Description

technical field [0001] The invention relates to an expansion card, especially a stably fixed expansion card, which can enhance the stability of the expansion card inserted into the socket of the mainboard, making it less susceptible to impact and detachment from the socket. Background technique [0002] The expansion card is a very important part of computer-related products. Its function is mainly to expand the functions of the computer. For example, the USB expansion card is used to provide the computer with the function of accessing the USB device; Source output to display images on an external display device; and existing expansion cards such as Figure 7 and Figure 8 As shown, contains: [0003] An expansion card body 70 has a plug board 71 protruding from its bottom, and a set of conductive contacts 711 are formed on the plug board 71 . [0004] The above-mentioned expansion card is plugged into the socket 91 of an external motherboard 90 with a tight fit, and the e...

Problems solved by technology

[0005] However, when the fixed baffle plate 80 locked by the screw 81 is deformed by external forces such as vibration or impact, it will form as follows: Figure 9 As shown, the plug board 71 of the expansion card body 70 is pulled out of the socket 91 obliquely, so that the expansion card and the main board 90 form an electrical insulation, so that the main board 90 cannot transmit data through the set of conductive contacts 711. data, causing the expansion card to fail to work. Therefore, this expansion card is not ideal and needs further improvement
