New type description: [Technical field to which the new type belongs] This creation relates to a grounding structure for a circuit board, especially a grounding structure for supporting a circuit board and conducting static electricity. [Previous technology] The main board of Biyuezi is installed in a metal body, and the main board is not in direct contact with the computer case, otherwise the main board will be short-circuited and damaged. ) The main board is suspended, and the main board is fixed on the bottom plate or the side plate of the computer case by using the column foot, so as to install the main board in the computer case. However, when the computer is operating, static charges are constantly generated, which causes the motherboard to continuously accumulate static and charge. When the static charges accumulate to a certain amount, a discharge phenomenon will occur, causing the electronic components on the motherboard to be damaged due to the discharge. Therefore, the main board must be equipped with a structure that can dissipate electrostatic charges to prevent the main board from being damaged by the effects of electrostatic charges. In Baizhi technology, a grounding structure for dissipating static electricity is installed on the motherboard, such as US Pat. Nos. 6,424,537 and 6,424,538. As shown in FIG. 4, it is provided on the printed circuit board 21 (pdnted circuit board). There are openings 22 'grounding patches 221 are provided on the upper surface of the openings 22, and a flexible clip 23 is clamped on the openings 22, and the elastic clips 23 are clips The grounding patch leaning above the opening η is as above, and another conductive pillar is called Gamma) is inserted into the opening 22 and the conductive pillar 24 contacts the elastic clamp 23, and the conductive pillar is fixed or abutted against On the computer case (not shown in the figure). The electrostatic charge accumulated on the 18050 5 M263718 printed circuit board 21 in this way can be conducted to the computer case ground through the grounding patch 22! Through the elastic clip 23 and the conductive post 24, thereby eliminating the electrostatic charge. The mouth clip 23 is attached to the flat plate 23, and is bent upward one by one, and the goose neck 232 (㈣k) in the shape of “” can be directly clamped on the edge of the opening 22 by the goose neck 232. Moreover, the top of the conductive pillar 24 has an annular recess 241 (around recess area). With the annular recess 241 leaning into the edge of the opening, the elastic center 23 is fixed on the opening U of the printed circuit board 21. And, a top plate 233 is extended above the crane neck 232 of the elastic clip 23, so that the electric pole 24 * after opening the hole 22, the top of the conductive column 24 can contact the top plate 233 of the elastic clip 23 and contact with it. However, there is a manufacturing tolerance margin between the opening width of the gooseneck 232 of the elastic clip 23 and the thickness of the printed circuit board 21, so that the elastic clip cannot completely contact the ground patch 221 of the printed circuit board 21, so it is easy to produce Poor contact conditions and failure to dissipate the electrostatic charge may result in damage to the printed circuit board when the electrostatic charge reaches saturation. Please refer to Figure 5, due to the opening of the gooseneck 232 of the elastic clip 23 The width is slightly larger than the thickness of the printed circuit board 2 丨. When the ring-shaped recess 241 of the electric column abuts the opening 22 of the printed circuit board 21 to fix the elastic clip 23 at the edge of the opening 22, the top of the conductive post 24 pushes the elastic clip 23 upward, so that the elastic clip 23 conforms to the goose. The neck 232 is deflected at the center of the lever, which causes the flat plate 231 of the elastic clip 23 to sway downward. In this way, a gap is created between the flat plate 231 and the printed ground patch 221, resulting in poor contact or no 6 at all. 18050 M263718
