Embodiment Construction

[0016] Please refer to FIG. 3 , the backplane assembly 100 of the present invention includes a backplane 110 and several fixing columns 120 , wherein these fixing columns 120 can snap fit with the motherboard 200 after passing through the backplane 110 , so that the backplane 110 can be pre-installed. It is installed on the bottom surface of the motherboard 200 to increase the strength of the motherboard 200 .

[0017] Wherein, a central processing unit 210 is installed at a corresponding position above the main board 200 , and a through hole 220 is correspondingly opened on the main board 200 around the central processing unit 210 , so that the fixing posts 120 can pass through and cooperate with each other.

[0018] The backboard 110 is roughly cross-shaped, and includes a substantially rectangular abutting portion 1102 and four fixing arms 1104 extending outward from the four corners of the abutting portion 1102, wherein the proximal end of each fixing arm 1104 A perforatio...

Abstract

The invention is a backboard combination, comprising a backboard butted against on one side of a mainboard and several fixing poles running through the backboard and the mainboard, where each fixing pole comprises a connecting part, one end of the connecting part has a stop end bigger than the connecting part and the other end of the connecting part is a fastening part, and the fixing pole runs through the backboard and the mianboard and then makes the backboard and the mainboard placed in between the stop end and the fastening part. And it uses the fixing poles to prefix the backboard combination on the mainboard, beneficial to package and transportation.

Description

【Technical field】 [0001] The invention relates to a fixing device for a heat sink, in particular to a backboard assembly for fixing the heat sink to a main board. 【Background technique】 [0002] With the continuous development of the electronic industry, the calorific value of the computer system is increasing, and the radiator has become an indispensable heat dissipation component for electronic components such as the central processing unit in the computer system. Correspondingly, various fixing devices are also widely used to fix the heat sink to the circuit board, so that the heat sink can be more closely attached to the electronic component, and the electronic component can dissipate heat. As the volume of the heat sink becomes larger and larger, the required fastening force is also larger, which easily leads to deformation of the circuit board. In order to prevent the deformation of the circuit board, a back plate is usually installed on the circuit board to enhance t...
