DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 3 As shown, an anti-static flexible circuit board includes a board body 1 and an adjustment component 6, conductive columns 5 are connected to both sides of the board body 1, and the adjustment component 6 is arranged at the other end of the conductive column 5, and the adjustment component 6 includes a side plate 601, a partition 602, an end plate 603, a slide bar 604, a slider 605, a first return spring 606, a second return spring 607, a first fixed seat 608, a support arm 609, a second fixed seat 610 and a grounding column 611, a partition 602 is fixed to the inner middle end of the side plate 601, and a slide bar 604 is penetrated in the middle of the partition 602, end plates 603 are arranged at both ends of the slide bar 604, and a slider 605 is slidably arranged on the outside of the slide bar 604, and the outside of the slide bar 604 is also sleeved with a first return spring 606 and a second return spring 607, a first fixed seat 608 is installed on one side of the slider 605, and the first fixed seat 60 The surface of 8 is connected to a support arm 609 through a rotating shaft, and the other end of the support arm 609 is connected to a second fixed seat 610 through a rotating shaft, and a grounding column 611 is arranged on the inner side of the second fixed seat 610, the end plate 603 is elastically connected to the slider 605 through a first return spring 606, and the slider 605 is elastically connected to the partition 602 through a second return spring 607, the first return spring 606 and the second return spring 607 are arranged in the same number, and the elastic force of the first return spring 606 is greater than the elastic force of the second return spring 607, the partition 602, the slide bar 604, the slide bar 605, the first fixed seat 608, the support arm 609, the second fixed seat 610 and the grounding column 611 are electrically connected in sequence, and the slide bar 604 and the grounding column 611 are parallel to each other, four conductive columns 5 are arranged, and the conductive column 5 is electrically connected to the partition 602 through the side plate 601.

[0022] The specific operation is as follows: the side plate 601, the partition 602, the sliding bar 604, the slider 605, the first fixed seat 608, the support arm 609, and the second fixed seat 610 are all conductive. The slider 605 is pushed to slide about the outside of the sliding bar 604 by the elastic force of the first return spring 606, so that the first fixed seat 608 following the displacement of the slider 605 changes the support angle of the support arm 609 to the second fixed seat 610. By adjusting the distance between the grounding column 611 and the sliding bar 604, the grounding column 611 meets the condition of being offset against the device casing, so that the static electricity can be drawn out by using the grounding column 611.

[0023] like Figure 1 As shown, a gold finger 2 is provided at the edge of the board body 1 , and a through hole 3 is opened on the gold finger 2 . A heat dissipation groove 4 is opened on the top surface of the board body 1 , and the heat dissipation grooves 4 are distributed at equal distances along the top surface of the board body 1 .

[0024] The specific operation is as follows: since each gold finger 2 is provided with a through hole 3, when the gold finger 2 is welded, excess solder can be poured into the through hole 3 and continue to flow downward, so that the welding is more firmly done after the solder solidifies; the heat dissipation groove 4 exposes the high heat area of ​​the board body 1, which is beneficial for the heat generated in the board body 1 to be quickly transferred to the outside of the board body 1, avoiding heat accumulation.

[0025] In summary, when the anti-static flexible circuit board is used, the grounding posts 611 in the two sets of adjustment components 6 are first squeezed, and the elastic force of the second return spring 607 is used to make the slider 605 on one side of the first fixed seat 608 supported by the support arm 609 overcome the elastic force of the first return spring 606 and slide along the outside of the slide rod 604 toward the end plate 603, so as to reduce the volume of the overall structure and facilitate placement into the device housing;

[0026] Then the board body 1 is welded. When welding the gold finger 2, the excess solder can be poured into the through hole 3 of each gold finger 2 and continue to flow downward, so that the board body 1 is more solid after the solder in the gap solidifies;

[0027] At this time, the grounding column 611 without external force will rely on the elastic force of the first return spring 606 to push the slider 605 to slide in the direction close to the partition 602 about the outside of the slide bar 604, so that the first fixed seat 608 following the displacement of the slider 605 changes the support angle of the support arm 609 to the second fixed seat 610. By increasing the distance between the grounding column 611 and the slide bar 604, the grounding column 611 meets the condition of abutting against the device shell, and no manual operation is required, which increases the convenience of adjustment. Since the conductive column 5, the side plate 601, the partition 602, the slide bar 604, the slider 605, the first fixed seat 608, the support arm 609, and the second fixed seat 610 are all conductive, the static electricity can be drawn out by using the grounding column 611;

[0028] At the same time, the equidistantly distributed heat dissipation slots 4 expose the high heat area of ​​the board body 1 , which is conducive to the rapid transfer of heat generated in the board body 1 to the outside of the board body 1 , avoiding heat accumulation and increasing the actual working life of the board body 1 .
