Problems solved by technology

However, using a metal heat sink installed on the memory stick to dissipate heat from the memory stick also brings new problems, that is, the electromagnetic wave radiated by the memory stick will couple to the metal heat sink to form an antenna effect to radiate electromagnetic waves outward, thereby generating electromagnetic interference

Embodiment Construction

[0013] see figure 1 A preferred embodiment of the motherboard 100 of the present invention includes a circuit board 10 , a memory slot 12 , a memory module 20 , a grounding element 30 and a heat sink 40 . Of course, the motherboard 100 also includes other elements, such as PCI slots, CPU slots, etc., since it has nothing to do with explaining the working principle of the present invention, therefore figure 1 Not shown.

[0014] The memory slot 12 is disposed on the circuit board 10 and is used for inserting the memory stick 20 so that the memory stick 20 communicates with other components (not shown) on the circuit board 10 .

[0015] The heat sink 40 is used to be installed on the memory stick 20 for dissipating heat from the memory stick 20 . A groove 42 is defined on the top of the heat sink 40 .

[0016] The grounding element 30 includes two conductive first hooks 32 and a conductive clip 34 .

[0017] The two first hooks 32 are disposed on the circuit board 10 and loc...

Abstract

A mainboard comprises a circuit board, a memory slot arranged on the circuit board, a memory bank inserted in the memory slot, a radiation sheet installed on the memory bank and a grounding element, wherein the grounding element comprises two conductive first clamp hooks respectively positioned on the circuit board at two sides of the memory slot and connected with the grounding element, and a conductive fastener comprising a fastening part and two second clamp hooks at two ends of the fastening part, the fastening part is abutted against the top of the radiation sheet, and the second clamp hooks are connected with the corresponding first clamp hooks to conduct electromagnetic wave radiating from the memory bank to the ground. The mainboard disclosed by the invention avoids the electromagnetic interference by the grounding element.

Description

technical field [0001] The invention relates to a main board. Background technique [0002] Most of the memory sticks of servers or personal computers are now equipped with metal heat sinks to solve the heat dissipation problem of the memory sticks. However, the use of metal heat sinks installed on the memory sticks to dissipate heat from the memory sticks also brings new problems, that is, the electromagnetic waves radiated by the memory sticks will couple to the metal heat sinks to form an antenna effect to radiate electromagnetic waves outward, thereby generating electromagnetic interference. Contents of the invention [0003] In view of the above, it is necessary to provide a motherboard to avoid electromagnetic interference. [0004] A mainboard, comprising a circuit board, a memory slot arranged on the circuit board, a memory bar plugged into the memory slot, a heat sink installed on the memory bar, and a grounding The grounding element includes two conductive firs...
