Detailed Description

For convenience of description, a coordinate system is now defined as shown in fig. 1.

As shown in fig. 1 and fig. 3, a baffle plate reinforcing structure of an expansion card 1 includes a target board 2 and an expansion card 1 inserted into the target board 2, wherein an elastic fixing piece 3 is disposed between a baffle plate 11 of the expansion card 1 and the target board 2.

Here, the target board 2 is a board for anchoring an interface of the expansion card 1, such as a motherboard or a function expansion card.

As shown in fig. 7, the elastic fixing piece 3 includes a fixing plate 31, an end of the fixing plate 31 close to the baffle 11 of the expansion card 1 is provided with an elastic plate 32 extending upward in a vertical direction, and the fixing plate 31 and the elastic plate 32 together form an L-shaped structure. As a specific embodiment, the fixed plate 31 and the elastic plate 32 described in the present embodiment are formed by bending a single plate.

As shown in fig. 4, the fixing plate 31 is fixedly connected to the target board 2 by screws, and as shown in fig. 7, the elastic plate 32 is provided at left and right sides thereof with clamping plates 33 respectively extending toward one side (i.e., front side) of the baffle plate 11 close to the expansion card 1. As a specific embodiment, the engaging plate 33 in the present embodiment is formed by bending.

As shown in fig. 2, the baffle 11 of the expansion card 1 is provided with a clamping hole 111 matching with the clamping plate 33. As a specific implementation manner, in this embodiment, the baffle 11 of the expansion card 1 is provided with a square-shaped clamping hole 111, that is, one clamping hole 111 is shared by two clamping plates 33, and when the clamping is in place, the two clamping plates 33 are inserted into the clamping hole 111.

As shown in fig. 8, a guide surface 331 extending obliquely downward is provided between the upper side and the front side of the engaging plate 33, and preferably, an included angle β between the guide surface 331 and a vertical plane is between 25 ° and 30 °. An anti-slip surface 332 inclined obliquely downwards is disposed between the lower side surface and the front side surface of the clamping plate 33, and preferably, an included angle α between the anti-slip surface 332 and the lower side surface is 105 ° to 115 °. When the guide surface 331 and the escape prevention surface 332 of the folded and engaged portion are located within these two design angles, the maximum effect of preventing the card skip can be obtained.

Further, as shown in fig. 11, when the clamping plate 33 of the elastic fixing plate 3 is just pressed on the lower side of the clamping hole 111, a certain distance is still provided between the upper side of the clamping plate 33 and the upper side of the clamping hole 111, so that in the process of plugging, the plugging depth is difficult to control, the lower side of the clamping plate 33 and the lower side of the clamping hole 111 are often plugged, after the pressing force during plugging is removed, the expansion card 1 rebounds upwards for a certain distance, at this time, the clamping plate 33 is pressed on the lower side of the clamping hole 111, which easily causes damage to the plugging portion between the expansion card 1 and the target board card 2.

For this purpose, as shown in fig. 7, the lower end of the elastic plate 32 is provided with an escape notch 321 with a downward opening, i.e. the fixed plate 31 and the elastic plate 32 together form a vacant area in the shape of a closed loop. As a specific implementation manner, the avoiding notch 321 in this embodiment is a U-shaped structure with an opening facing downward. The fixing plate 31 is provided with a limiting plate 34 which extends upwards along the vertical direction in the avoiding notch 321, and the front side and the rear side of the limiting plate 34 are flush with the front side and the rear side of the elastic plate 32 respectively. The limiting plate 34 is provided with a limiting groove 341 with an upward opening. Preferably, the limiting groove 341 is in a U-shaped structure. As shown in fig. 5 and 6, the retaining plate 11 of the expansion card 1 is provided with a positioning post 112 engaged with the limiting groove 341. As shown in fig. 4, when the positioning column 112 presses against the lower end of the limiting groove 341, the engaging plate 33 just presses against the lower side of the engaging hole 111.

As shown in fig. 9, 10 and 11, since the limit plate 34 is connected to the fixed plate 31, when the elastic plate 32 is elastically deformed by the pressing action of the snap-in portion and the baffle plate 11, the limit plate 34 does not follow the elastic plate 32 to be elastically deformed. The position of the position-limiting plate 34 is maintained during the whole process of mounting and dismounting, so that the position of the position-limiting groove 341 can be accurately calculated, thereby ensuring that the engaging plate 33 is just pressed against the lower side surface of the engaging hole 111 when the positioning column 112 is pressed against the lower end portion of the position-limiting groove 341.
