Description

Support, main board device and electronic equipment for fixing two high-grade to-be-fixed cards simultaneously

Technical Field

The disclosure relates to the technical field of fixing a memory card of an electronic device, and in particular relates to a bracket, a main board device and an electronic device for simultaneously fixing two kinds of cards to be fixed in height.

Background

In the electronic equipment, because the space of some mainboards is limited, when two M.2 cards with different heights are required to be placed on the mainboards, two cards are stacked and fixed during design, so that the space on the mainboards is saved. When two cards are stacked together, a stud is required to be welded on a main board, then when a lower card (such as a Wifi card) is fixed, a hexagonal stud is used for locking and attaching to the welded main board stud, so that the lower card is fixed, and finally when an upper card (such as an SSD card) is assembled, a screw is used for locking and attaching to the hexagonal stud, and the upper card is fixed.

The disadvantage of this assembly is that, firstly, the fixed lower clamp needs to be fixed by a hexagonal sleeve, and when the Fang Kashi locking screw is assembled, different tools on the production line are required to be used in a switching mode, so that the efficiency is affected. Secondly, when the screw for fixing the upper clamp is dismounted, the hexagonal stud below can rotate along with the screw, so that the screw is difficult to dismount. Thirdly, the two cards are selectively configured according to actual needs, so that a user needs to use two tools, namely a hexagonal sleeve and a screwdriver when the user installs, removes and replaces the two tools according to needs, the user does not need to have corresponding tools, and the cost is increased if the manufacturer assembles the tools. Fourth, if the below card is the wifi card, the antenna of wifi card has the risk that drops because the top does not have fixed knot to construct. Thus, there is a need for improvements in the manner of such mounting fixtures currently available.
