Description of the Invention: [Technical Field] The present invention relates to an expansion card, and more particularly to a stable and fixed expansion card, which can enhance the stability of the expansion card inserted into the motherboard socket. [Previous technology] The expansion card is a very important part of the computer-related products. Its function is mainly to expand the functions of the computer. For example, the USB expansion card is used to provide a computer to access the USB device. The video expansion card is used to provide a computer to output the image source and display the image by an external display device; and the existing expansion card is as shown in FIG. 5 and FIG. 6, which includes: an expansion card body 70' A plug-in board 71 is formed on the side of the plug, and a set of conductive contacts 71 is formed on the plug-in board 71. The expansion card is inserted into the socket 91 of an external motherboard 9A. The socket 91 is formed with an electrical connection corresponding to the set of conductive contacts 711 of the connector board 7 a plurality of angled blocks 92 are formed on the outer wall surface of the socket 91. When the plug-in board 71 is inserted into the socket 91, the set of conductive contacts 7" and the power in the socket 91 are electrically connected. The contact is formed into a contact connection, so that the expansion card is electrically connected to the motherboard 9G, and the plug-in board 71 is tightly fitted into the socket 91 of the motherboard 9Q, and is susceptible to vibration. Further, a fixing baffle 80 is disposed on a side of the expansion card body 7 perpendicular to the bottom edge thereof. The fixing baffle 82 is configured to pass through the screw 81 and is screwed to the main body casing to further fix the expansion card body 7然而 However, when the fixing board 8 which is locked by the screw 81 is deformed by an external force such as vibration or impact 201246714, it will be formed as shown in Fig. 7, and the insertion board 71 of the expansion card body 7〇 is pulled out obliquely. The socket 91 electrically insulates the expansion card from the motherboard 9' so that the motherboard 90 cannot pass through the motherboard The conductive contact 711 transmits data, so that the expansion card cannot operate. Therefore, the expansion card is not ideal and needs further improvement. [Invention] In view of the technical defects of the above-mentioned existing expansion card fixing instability, the main object of the present invention is An expansion card with a beveled block is provided to securely fasten the expansion card to the docking station. The main technical means for achieving the above purpose is to enable the securely fixed expansion card to include: a bottom plate is formed with a plug-in board, and the plug-in board is formed with a set of conductive contacts; a latching member includes a connecting board and a hook portion; wherein the hook portion is from the bottom surface of the connecting board The lower extension 'and one side of the connecting board is fixed on the expansion card body', so that the hook portion is spaced apart from the insertion board of the expansion card body. The expansion card of the invention has the fastening component, so when the connector is inserted When the board is inserted into the socket, the hook portion of the clip member is fixed to the bevel block of the outer wall surface of the plug socket, so that the plug board is firmly fixed in the plug socket; Pull off For example, the expansion card of the present invention can be pulled out from the socket by releasing the hook state of the hook portion and the socket block of the socket. [Embodiment] 4 Summer 201246714 Please refer to FIG. 1 and 2, the expansion card of the present invention includes: an expansion card body 10, a bottom side of which protrudes to form a plug-in board 11, and a plurality of conductive contacts 111 are formed on the plug-in board; The member 20 includes a connecting plate 21 and a hook portion 22; wherein the hook portion 22 extends downward from the bottom surface of the connecting plate 21, and one side of the connecting plate 21 is fixed to the expansion card body 1 The hook portion 22 is spaced apart from the plug-in board of the card body 10, and in the embodiment, the connecting board 21 is fixed to the end surface of the side of the expansion card body 1 - a plurality of screw holes 211 are formed, and The expansion card body 1 is also formed with a plurality of through holes 101 corresponding to the positions of the plurality of screw holes 211. Thus, the plurality of screws 212 can be respectively passed through the plurality of through holes 1〇1 of the expansion card body 1 and then screwed into the screw holes of the connecting plate 21. In 211, the fastening component 20 is screwed and fixed on the expansion card body 1〇; The 22 series includes a plurality of connecting rods 221 and a horizontal connecting strip 222. The plurality of connecting rods 221 are parallel and juxtaposed, and one end is common from 2, and the bottom surface extends downwards. The horizontal strips 222 are connected to the plurality of connecting rods 221 in common. At the other end, the horizontal hook 222 is further formed with an upper hook portion 2221 toward the side of the plug-in board 11. The expansion card body 10 further includes: a fixed baffle 30 ′ is disposed on one side of the expansion card body 1 垂直 perpendicular to the bottom edge thereof; the plurality of fixing pieces 31 are connected to the expansion by the fixed baffle 30 One side of the side of the card body 1 extends outwardly and is respectively screwed and fixed to the expansion card body 10; a casing fixing piece 32 extends outward from the top edge of the fixed baffle 30, 5 201246714 The direction is opposite to the extension of the plurality of fixing pieces 31 for screwing with the external main body casing. Referring to FIG. 3 and FIG. 4A to FIG. 4C again, in use, the plug-in board 11 of the present invention is inserted into the socket 91 of the external motherboard, when the plug-in board 11 of the present invention is aligned with the socket 91. The upper hook portion 2221 of the horizontal hook 222 of the hook portion 22 is aligned with the plurality of oblique angle blocks 92, and then the downwardly biasing force is applied to insert the insertion board 11 into the socket seat 91. At this time, the horizontal hook strip 222 The deformation is outwardly bent. When the insertion plate 11 is fully inserted into the insertion seat 91, the upper hook portion 2221 of the horizontal hook 222 also passes through the oblique block 92, and due to the elastic restoring force of the connecting rod 221, The upper hook portion 2221 of the horizontal hook 222 is hooked to the bottom of the plurality of oblique blocks 92. Therefore, the user only needs to insert the insertion board into the insertion interface of the socket 91, and when there is an external force to pull the insertion board 11 out of the socket 91, the buckle The hook portion 22 of the member 20 will be securely fixed in the socket 91 by the bevel block 92' of the wall portion of the socket 91 by the upper hook portion 2221. The present invention is provided with the latching member, and can be hooked to the oblique block of the outer wall surface of the plug-in seat when the plug-in board is inserted into the socket of the motherboard, and the plug-in board can be stably inserted. It is disposed in the socket, so it is not easily subjected to external forces such as impact or vibration and is released from the socket.
