Motherboard assembly

Abstract

The invention discloses a motherboard assembly applicable to an expansion card. The motherboard assembly comprises a circuit board, an expansion port and a buckling device, wherein the buckling devicecomprises an assembling body, a limiting body and a buckling body; the assembling body is installed onto the circuit board; the limiting body is connected to one side, far away from the expansion port, of the assembling body by bending and can rotate, relative to the assembling body, between a limiting position and an opening position; the buckling body is connected to the assembling body by bending and can rotate, relative to the buckling body, between a pressing position and a releasing position. When at the limiting position, the limiting body props against one side, far away from the expansion port, of the expansion card, and is pressed by the buckling body at the pressing position to be fixed to the limiting position; when the buckling body is at the releasing position, the limitingbody is released from the pressing of the buckling body.

Description

technical field [0001] The present invention relates to an electronic device, in particular to a motherboard assembly including an expansion card fixing device. Background technique [0002] In addition to the electronic devices that provide basic functions such as the central processing unit and power supply, the motherboard of the computer equipment is also equipped with expansion slots, which can be expanded by inserting expansion cards when users have additional functional requirements. Computer function. For example, when the user needs to access the Internet wirelessly, but the host computer does not have a built-in wireless network card, the user can selectively add a wireless network card to the host computer to implement the function of wireless Internet access. [0003] Due to the elasticity of the plastic elastic arms, when the user wants to insert the expansion card into the expansion port, he needs to spread the elastic arms of the two plastic fasteners with bo...
