Problems solved by technology

However, this fixing method indirectly fixes the expansion card by fixing the metal bracket on one side of the expansion card. When the computer is subjected to unexpected impact or the expansion card is long, the expansion card is prone to loosening, which affects the connection between the expansion card and the computer. The electrical connection relationship of the motherboard

Embodiment Construction

[0026] see Figure 1 to Figure 2 , In a preferred embodiment of the present invention, an expansion card fixing device is used to fix a plurality of expansion cards 50 on a circuit board 40 inside a casing 10 . The circuit board 40 is provided with a slot 41 for connecting the expansion card 50 . One side of the expansion card 50 is connected to a blocking piece 51 , and the lower edge is provided with an inserting portion 52 for inserting into the slot 41 . The blocking piece 51 is substantially “L”-shaped, including an end portion 511 bent from a top edge of the blocking piece 51 .

[0027] The casing 10 includes a bottom plate 16 and a side plate 17 vertically connected to the bottom plate 16 . The circuit board 40 is installed on the bottom plate 16 , and a plurality of adjacent expansion slots 11 are defined on the side plate 17 , and the upper part of the expansion slots 11 is bent to form a carrying piece 12 . A pair of pivoting pieces 13 are vertically bent at two e...

Abstract

A single mounting apparatus for securing a number of expansion cards includes a resisting member rotatably attached to the chassis and a clamping buckle. The clamping buckle includes a pressing piece, a supporting portion, an operating portion, and a catching member. A securing space is defined in the resisting member for latching the catching member. When the catching member is caught in the securing space, the securing member is clamped between a flange of the chassis and the resisting member to stop the rotation of the resisting member. The pressing piece presses down on and secures the expansion cards. Lifting the clamping buckle upwards unlatches the catching member from the securing space and causes re-rotation of the resisting member to allow dismounting of the expansion cards.

Description

technical field [0001] The invention relates to a fixing device, in particular to an expansion card fixing device. Background technique [0002] Various expansion cards (such as sound cards, network cards, etc.) that comply with the PCI (Peripheral Component Interconnect) standard are widely used in various electronic devices. The expansion card realizes the connection with the electronic equipment and the installation of the expansion card in the electronic equipment by plugging the pins into the PCI slot of the electronic equipment. In order to prevent the expansion card from loosening, one side of the expansion card is usually fixed with a metal baffle. After the expansion card is inserted into the corresponding expansion card slot on the motherboard, the metal baffle of the expansion card is fixed on the computer case. to ensure that the expansion card will not fall off during the process of moving the computer. However, this fixing method indirectly fixes the expansio...
