Description of the invention: [Technical field to which the invention pertains] * The invention relates to a board-mounting device for a board-and-board device, especially an electronic device. [Prior Art] Tian Hao, modern electronic devices such as personal computers and servers have developed rapidly. The CPU has become the largest component of the internal heat generation of these electronic devices. People often use the heat sink to actively dissipate heat. Some boards, such as boards that integrate multiple memory chips, expansion cards, etc., do not receive the attention they deserve, although they generate a lot of heat during operation. Generally, the cards are fixed to the electronic device side by side by means of a buckle, but the buckles are mostly located at one end or both ends of the card, for example, the buckle structure of the fixed circuit board is located at both ends of the circuit board, so that These buckles will occupy the space between two adjacent boards. These spaces are the passages through which the airflow of the boards flows, so that the buckles will block the passage of the airflow, which reduces the airflow between the two boards, which is not conducive to Board cooling. "Because it is necessary to improve the conventional card fixing device to remove the above-mentioned missing. [Inventive content] In view of the above inner valley, it is necessary to provide a card fixing device that is advantageous for heat dissipation. The connector 4 for fixing a card to the motherboard has a plurality of card slots, and the card fixing device includes at least 7 201025754 / a card formed by bending a plate, the at least one card includes a card The top wall and the two side walls extending from the same side of the top wall in the same direction, the inner side of the top wall is provided with a spring piece elastically resisting the top surface of the card, and the lower part of each side wall is provided with a groove and forms two The elastic portion further extends to form a card having a card protrusion. When the card is inserted into the connector of the motherboard, the plate is clamped between the two sidewalls of the card, and the two legs of each sidewall The card is fixed in the corresponding card slot, and the card protrusions of the two card legs are respectively fastened to the edge of the corresponding card slot to fix the card card. Compared with the Xiao Xizhi technology, the card fastener of the card fixing device is made of plate material and takes up space. Small, enlarged The air flow channel between the two adjacent boards reduces the resistance to the air flow, and increases the air flow through the card to facilitate the heat dissipation of the card, and when the card protrusion of the card is separated from the edge of the corresponding slot, The card foot can automatically pull out the corresponding card slot under the elastic restoring force of the elastic piece to facilitate the disassembly. [Embodiment] Referring to FIG. 1, a preferred embodiment of the card fixing device of the present invention is used for the card card. 100 is fixed to the motherboard 200, which includes two card firmwares 3. In the embodiment, the card is a circuit board integrated with a plurality of memory chips, and a plug portion with a row of conductive pins is arranged at the bottom of the board. The pair of opposite ends respectively form a fixing portion ι 4 . The motherboard 200 is provided with a long connector 2 〇. The connection includes a top surface 2 and a vertical downward direction from the top surface 21 The two opposite sides: the surface 23' of the top surface 21 defines a slot 22 for inserting the plug portion ι 2 of the card 1. The two side faces 23 of the connector 2 are respectively convex near the two ends Set one card 8 201025754 ♦ Holder 24, each card holder 24 opens _ card slot %. Please continue to participate Figure 2, in the implementation of the Taixiang Shishi Shishifeng, the two card firmware 3〇, which is made of sheet metal bent. Each - Shiyang from 1 mother card firmware 30 includes a top wall 32 and from - The two sides of the top wall 32 are bent downwardly to form two opposite side walls 34. The two side walls 34 form a receiving space between the two side walls 34 for receiving the fixing portion 1〇4 of the lever. 36' The top wall 32 is provided with a strong slanting 38 in the 3 ό 罝 〆 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 An elastic/ — is formed on each side of the slot 39, and the bottom end of each elastic portion 40 extends away from the corresponding side wall 34 to form an L-shaped latching portion 41. The latching portion 41 includes a horizontally disposed support section 42 and a vertically disposed latching foot 44. Each of the card feet is ugly and the outer edge of the sigh is further extended outward to form a cymbal 46 with the card foot 44 being coplanar. The outer side edge of the female support section 42 is vertically formed upwardly to form a flap 48. In other embodiments, the two fasteners 30 can also be made of other sheets such as plastic drive: 目. 乂, etc.; the pull can also be placed at other positions of the support section 42. Referring to FIG. 3 to FIG. 3 at the same time, during assembly, the card is inserted into the slot 22 of the cymbal connector 20. The opposite elastic portions of each of the side walls 34 are pressed opposite each other. 40, causing the elastic deformation thereof and the (4) firmware 3〇 is set on the two fastening plates of the card, so that the fastening portion 41 extends the card slot of the corresponding holding portion 24 of the connector 2G. 6, f when 'the two card firmware 30 of the elastic piece 38 is elastically deformed, and two: against the top surface of the fixed portion 104. Release the two fasteners 30, each elastic pair 40 elastically recovers The latching portion 46 of the corresponding latching portion 41 "stops" at the bottom of the corresponding latching portion 24; and the branch portions 9 201025754 of the two latching members 30 are respectively abutted against the top surface of the connector 2 . And the surface 23 〇, when the board (10) is taken out, the two clamping pieces 48' of each side wall .34 of the two fasteners 30 are pressed opposite each other to cause the corresponding elastic portion 4 and the holding portion 41 to be elastically depressed. The tabs 46 of the two latching legs 44 are disengaged from the corresponding latching portions. =, corresponding to the elastic recovery of the elastic piece 38 and the card firmware card = should be the card slot 26, that is, from the connector - 2 from the phase of the library side 2, the method of the 'mother-card piece' of the card foot 44 can be directly from the corresponding (four) 34 The elastic portion 4〇 is formed to extend, that is, 42' is omitted and the plate spring 48 can be bent and disposed on the elastic portion 40. At this time, the card slot corresponding to the foot 44 is opened at the connector 2 1 end and the opposite card legs - when inserted into the corresponding card slot 26: 2: the card dog 46 card is placed at the inner edge of the card slot 26 Secure the connector 2〇. ^2: The two card firmware 3〇 is made of sheet metal, and is held substantially in parallel with the ❹ ❹ , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Can increase the flow through;; very conducive to the card cooling. Moreover, when the ... is in the corresponding holding portion 24, the card legs out of the corresponding card slot 26, which facilitates the automatic lifting of the elastic recovery force =:::=. The scope of the above is not limited to the above-mentioned implementation. For those who are familiar with the skill of this 201025754, the equivalent modification in the spirit of the invention should be covered in the following patent applications. Within the scope.
