Expansion card

Abstract

The invention discloses an expansion card. The expansion card comprises an expansion card body and a hooking component, wherein the expansion card body extends at the bottom to form a plug board provided with a golden finger area; a bolting hole and a hooking edge are formed on the two opposite edges of the plug board; a distance between the bolting hole and the hooking edge is greater than the width of the golden finger area; the hooking component comprises a connecting board and a hooking part; a bolting component is formed on the connecting board corresponding to the bolting hole; a fixinghook is formed on the connecting board corresponding to the hooking edge; the fixing hook is hooked on the hooking edge to fix the bolting component to the bolting hole; and the hooking part laterally extends to form a shifting sheet. Therefore, the expansion card is convenient to mount and demount in a way that the shifting sheet is shifted by a hand of a user. A metal lead to be connected with a golden finger on an expansion board can linearly enter the golden finger area, and the efficiency of a product is improved.

Description

technical field [0001] The invention relates to an expansion card, especially an expansion card which can be buckled with a socket, is easy to disassemble and does not affect electrical characteristics. 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 an existing expansion card has the effect of strengthening the fixing force, such as Figure 8 As shown, contains: [0003] An expansion card body 70 has a plug board 71 protruding from its bottom edge, and a plurality of fastening holes 72 arranged in a row are formed near the plug board 71, and a group of golden fingers 73 are formed on the plug board 71 ; [0004] A hook fastener 80 includes a connecting plate 81 and a hook por...

AI Technical Summary

Problems solved by technology

[0007] 1. Difficult to disassemble: After the expansion card is inserted into the socket 91, the horizontal hook bar 83 will hook the plurality of angled blocks 93, therefore, when the expansion card is to be removed, the hook portion of the hook fastener 80 must be released first 82 and the plurality of angled blocks 93 are hooked, but the only place where the user can pull is the bottom of the hook part 82 of the hook fastener 80, and the hook part 82 is quite close to the circuit board 92 located below, so it is difficult for fingers to reach Between the hook portion 82 and the circuit board 92, therefore, tools such as a screwdriver must be inserted to hook the hook portion 82; it is troublesome to disassemble and overhaul the expansion board.

[0008] 2. The electrical characteristics of the expansion card are easily affected: the gold fingers 73 provide components for the expansion card to be electrically connected to the socket 91, so a plurality of metal wires 74 and the group of gold fingers must be formed on the expansion card body 70 73 connection, but because the main body 70 of the expansion card forms a whole row of fastening holes 72 to fasten the hook fastener 80, the plurality of metal wires 74 must avoid the plurality of fastening holes 72 arranged in a whole row and be placed in multiple places. Bending is formed, which affects the performance of the product and the electromagnetic interference value (EMI value) of the entire expansion card
