Embodiment Construction

[0011] Please refer to figure 1 and figure 2 , the fixing member of the present invention is used to fix a radiator 10 on a motherboard 20 . An electronic component 22 is disposed on the motherboard 20 . The motherboard 20 defines at least one through hole 24 on two sides of the electronic component 22 respectively.

[0012] The heat sink 10 includes a bottom plate 12 and a plurality of cooling fins 14 vertically extending upward from a top surface of the bottom plate 12 . The bottom plate 12 defines at least two through holes 120 corresponding to the through holes 24 of the main board 20 .

[0013] The fixing member includes a body 30 , a spring 40 and a washer 50 . The main body 30 includes a cylinder 31 , two parallel buckles 32 disposed on the top of the cylinder 31 , and two parallel locking feet 34 disposed on the bottom of the cylinder 31 . Half-conical locking teeth 320 respectively protrude from the ends of the two buckles 32 . Two semi-conical protrusions 340 ...

Abstract

A fastener comprises a body, a gasket and a spring. The body comprises a column body, two clamping buckles arranged at the top end of the column body and two clamping feet arranged at the bottom end of the column body, an annular stopping part is arranged on the circumferential surface, close to the clamping feet, of the column body, the tail ends of the two clamping buckles are respectively provided a semi-conical clamping tooth in a protruding mode in the backward direction, and the tail ends of the two clamping feet are respectively provided a semi-conical protrusion in a protruding mode in the backward direction. The gasket is arranged on the column body in a sleeved mode, and the spring is arranged on the column body in a sleeved mode and is arranged between the gasket and the stopping part in a sandwiching mode. The clamping buckles and the clamping feet of the fastener can be clamped into two workpieces respectively to fix the two workpieces relatively, space cannot be occupied, and the fastener is quite convenient to use.

Description

technical field [0001] The invention relates to a fixing piece. Background technique [0002] In the prior art, screws are often used to pass through the heat sink and the main board and lock into nuts to fix the heat sink on the electronic components. However, this fixing method takes up a lot of space, and it is often necessary to cut the cooling fins to free up the installation space, which is not only cumbersome, but also weakens the heat dissipation function of the radiator. Contents of the invention [0003] In view of the above, it is necessary to provide a space-saving fixture for conveniently fixing two workpieces. [0004] A fixing piece, including a body, a gasket and a spring, the body includes a cylinder, two buckles on the top of the cylinder and two clamping feet on the bottom of the cylinder, the cylinder A ring-shaped stop portion protrudes from the circumferential surface of the two buckles adjacent to the clamping feet. Half-conical locking teeth protr...
