Description

M259454 V. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is about a motherboard that can quickly and easily fix a motherboard with a good grounding effect in the electronics. [Previous technology] The motherboard is a computer system. Can affect the performance of computer systems. The electronic component solder joints on the board are short-circuited with the computer. Therefore, the industry uses a method to avoid the constant increase in the phase ratio between the motherboard and the computer case. More and more electronic components are generated after a certain amount of static load is accumulated to make the motherboard. Cannot be imported underground. In order to solve the above problem, the previous main board fixing device is required. The main device disclosed in No. 992 1 6650 · 0 includes a head and a head-located material, and includes a first abutting portion provided along the axial direction. The design that penetrates the first abutment groove makes the perforation of the motherboard to achieve the positioning effect. However, it depends on the elastic tension of the head to take the motherboard fixing device from the head, especially to install or remove the motherboard and the fixture in a simple structure. Dirty 'its fixing in the electronic device When fixing the main board, avoid contact of the main body case to cause the circuit of the main board. A fixing device to fix the main board is the same contact. As the operating frequency of the motherboard accumulates on the motherboard, when the static electricity discharge phenomenon will break through some sensitive normal operations, it is necessary to improve these electrostatic charges to the motherboard fixing device. A kind of device, such as the mainland China patent application machine board fixing device, the pillar part of the main board fixing part, the head is conductive and a second contact part, the central position of the head and the second contact part is slotted, relying on the opening After positioning, the head elastic expansion method depends on the head elastic fixing method, and when disassembling, the head needs to be retracted and out, which is extremely inconvenient.

Page 5 M259454 V. Creation instructions (2) The body is ring-shaped by the body of the guide post, and it is set on the arrangement of parts that cannot be plated by the board fixing element. For example, Chinese Patent No. 0227 1 33 1 · X, which includes a support body and an elastic sheet, which is made of electrical material, including a head, one connected to the head = ^, and one connected to the first pillar portion. The second cylindrical body portion has a large elastic sheet, an opening is provided in the center, and the annular elastic sheet is corrugated along the circumferential direction, and is provided with at least one upper pressing portion and at least one lower pressing portion. The spring plate and the support body, a main board is clamped to the first column part of the support body, and the main plate is fixed by the abutment of the spring plate. However, using this type of machine method 'because there are no electronic solder joints in the area where the motherboard is in contact with the shrapnel', that is, no plug-in electronic components can be placed in these areas, and the wiring is routed in the areas on the bottom layer of the motherboard. It will reduce the space for the placement and wiring of the motherboard, increase the difficulty for motherboard designers to perform zero-sum wiring, and each support needs to cooperate with an elastic piece. A motherboard requires a large number of elastic pieces, which increases the cost. In summary, there are deficiencies in the ejection device of the conventional knowledge. [Content] The purpose of this creation is to provide a motherboard fixing device, especially a motherboard with a simple structure, which can quickly and easily install or remove a motherboard in an electronic device, and a motherboard fixing device with a good grounding effect. The original motherboard fixing device is used to fix a motherboard with a plurality of mounting holes and openings in an electronic device. The motherboard fixing device includes a bearing plate and a plurality of supporting bodies matched with the mounting holes. The carrier board is provided with a card body and a boss, the card body includes a hook, and the boss is provided with a

A round boss 39 is also provided on the side of the carrying plate 30. The boss β has a screw hole 391 on the top β, and a manual screw 90 can be locked in the screw hole 09 1 ° The support body 40 series It is made of a conductive material, and includes a head portion, a first pillar portion 44 connected to the head portion 42 and located below the head portion 42, and a first pillar portion 44 connected to the first pillar portion 44 and located on the first The second cylinder portion 46 below the cylinder portion 44. The head portion 42 is formed from an outer diameter from small to large from top to bottom, and an introduction portion 422 and a second introduction portion 424 from large to small outer diameter. The diameter of the cross-sectional area at the junction of the first introduction portion 422 and the second introduction portion 424 is the largest on the entire head portion 42. The head portion 42 is provided with an annular pressing surface 426 on the bottom surface of the second introduction portion 424. The first cylindrical portion 44 extends vertically downward from the annular f-pressing surface 426 of the head portion 42 and has a length equal to the thickness of the motherboard 10. The cross-sectional diameter of the first cylindrical portion 44 is smaller than the annular pressing surface. 4 2 6 outer ring diameter. The second pillar portion 46 extends axially along the first pillar portion 44, and a bearing surface 462 is formed at a point where the first pillar portion meets the first pillar portion. A cross-sectional diameter of a cylindrical portion 44 is smaller than an outer ring diameter of the pressing surface 426 of the head portion 42 and a cross-sectional diameter of the second cylindrical portion 46, so that the first cylindrical portion 44 becomes the head. A circular groove between the portion 42 and the second pillar portion 46. The motherboard 60 is provided with a plurality of mounting holes 62 and a plurality of openings 64.

M259454 V. Creative Instructions (5) " The mounting hole 62 is approximately a gourd shape, and includes a circular hole 622 and a slot 624 connected to the circular hole. The diameter of the circular hole 622 is larger than the maximum cross section of the head 42 and smaller than the diameter of the bearing surface 462. The head 42 can pass through the circular hole 622. The width of the slot 624 is slightly larger than the cross-sectional diameter of the first pillar portion 44 and smaller than the cross-sectional diameter of the second introduction portion 424 at a certain height. The opening 64 includes a square opening 642, a rectangular opening 644 and a circular opening 646. The length of the slot 624 is substantially equal to the width of the square opening 642 and the rectangular opening 644. Please refer to the third and fourth figures together to assemble the motherboard to the computer case 20 so that the support body 40 on the carrier board 30 is vertically upward, and the circular holes 622 of the motherboard 60 are respectively Align the head 42 of the support body 40, the square opening 642 with the acute-angle hook 367 of the acute-angle card body 36, and the rectangular opening 644 with the fan-loop hook 387 of the fan-ring card body 38, The circular hole 622, the square opening 642, and the rectangular opening 644 of the main board 60 pass through the head 42 of the support body 40, the acute-angle card body 36, and the fan ring card body 38, respectively. The main board 60 The bottoms are respectively connected to the supporting surface 462 of the supporting body 40, the horizontal portion 365 of the acute-angle card body%, and the horizontal wall 385 of the fan ring card body 38, thereby carrying the main board 60.
