[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0022] Reference attached Figure 1-3 This embodiment includes two clamps 1 arranged oppositely, a height adjustment assembly 2 is provided between the two clamps 1, and the height adjustment assembly 2 is hinged to the two clamps 1; the clamp 1 includes an upper splint 11 and a lower splint 12, A sliding group and a spring group are arranged between the splint 11 and the lower splint 12, so that the upper splint 11 and the lower splint 12 are opened or clamped in the height direction. Both ends of the clamp 1 are provided with clamps 13 which are respectively connected to the upper splint. 11 and the lower splint 12 are rotatably connected, and the clamp 13, the sliding group and the spring group are all arranged along one long side of the upper splint 11.
[0023] There are two clamps 13 and they are respectively provided at both ends of the clamp 1. By pressing the two clamps 13, the upper clamping plate 11 and the lower clamping plate 12 are opened, so that the PCB board can be easily inserted between the upper clamping plate 11 and the lower clamping plate 12.
[0024] The height adjustment assembly 2 includes a screw 21, a plurality of sliding parts 22 are sleeved on the screw 21, the sliding part 22 is threadedly connected with the screw 21, and a plurality of first rods 23 are arranged between the sliding part 22 and the upper splint 11, The two ends of the first rod 23 are respectively hinged to the upper splint 11 and the sliding member 22, a plurality of second rods 24 are arranged between the sliding member 22 and the lower splint 12, and the two ends of the second rod 24 are respectively connected to the lower splint 12 and sliding The pieces 22 are hinged, and the multiple first rods 23 and the multiple second rods 24 can keep the structure between the two clamps 1 stable. The rotation directions of the threads at both ends of the lead screw 21 are opposite, and the multiple sliding pieces 22 are respectively arranged on Both ends of the screw 21. In this embodiment, there are two sliding members 22. There is a handle on one end of the screw 21. By rotating the handle, the screw 21 is rotated, so that the two sliding parts 22 move back to each other or move toward each other, which drives the distance between the two clamps 1 to increase or decrease, that is, two The height between each clamp 1 becomes larger or smaller. Since there are many electronic components installed on the PCB, the height of each PCB board is different. When the two PCB boards are fixed on the PCB board connection structure by the fixture 1, the height between the two fixtures 1 needs to be adjusted to make The two PCB boards do not affect each other.
[0025] The spring set includes a plurality of springs 14 arranged in an array between the upper clamping plate 11 and the lower clamping plate 12. One end of the spring 14 is fixed on the upper clamping plate 11 and the other end is fixed on the lower clamping plate 12. In this embodiment, the spring 14 is a tension spring. Press the clamp 13 to open the upper splint 11 and the lower splint 12, put the PCB board in, loosen the clamp 13, and the tension spring makes the upper splint 11 and the lower splint 12 clamp the PCB tightly under the tension.
[0026] The sliding group includes a plurality of sliding rods 15, both ends of the sliding rod 15 are slidably connected to the upper splint 11 and the lower splint 12 respectively. By setting the sliding rod 15, the upper splint 11 and the lower splint 12 slide up and down to facilitate the insertion and clamping of the PCB board.
[0027] The long side of the upper splint 11 is divided into side A and side B. The clip 13, the sliding group and the spring group are all arranged along the side B, and the distance from the sliding group to the side A is smaller than the distance from the spring group to the side B. With this arrangement, when the PCB board is inserted between the upper clamping plate 11 and the lower clamping plate 12, it first abuts the sliding group to avoid contact between the PCB board and the spring group, thereby being damaged by the spring group. The clamp 13 is loosened, the upper splint 11 and the lower splint 12 clamp the PCB board. By setting the sliding group, it is convenient to control the depth of the PCB board insertion and to quickly insert the PCB board.
[0028] Both the upper splint 11 and the lower splint 12 are provided with an opening 3, the opening 3 is arranged in the direction of side A, the cross section of the opening 3 is trapezoidal, and the distance between the two openings 3 changes from side A to side B small. Through this setting, it is convenient for the PCB board to be easily inserted into the fixture 1.
[0029] Both the upper splint 11 and the lower splint 12 are provided with buffer rubber pads, and the buffer rubber pads of the upper splint 11 and the lower splint 12 are arranged oppositely. By setting the cushion rubber pad, the PCB board can be avoided as much as possible while clamping the PCB board.
[0030] The clamp 13 includes two clamp handles 131, the two clamp handles 131 are respectively rotatably connected with the upper splint 11 and the lower splint 12, a support rod 132 is arranged between the two clamp handles 131, and two ends of the support rod 132 are respectively connected to two clamps. The handle 131 is hinged. Press the two clamp handles 131 to open the clamp 1 to facilitate the insertion of the PCB board. Loosen the clamp handle 131, and the tension spring makes the clamp 1 clamp the PCB board tightly, and then move the clamp 13 to the clamp 1 according to the use environment. On the long side or the short side, in practice, in which direction the space in the length direction or the width direction of the installation environment is tight, the clip 13 is moved to the other direction, so that the clip 13 affects the installation environment as little as possible.
[0031] The upper clamping plate 11 and the lower clamping plate 12 are arranged in parallel, which is convenient for the fixture 1 to clamp the PCB board.
[0032] The two clamping handles 131 are arranged in parallel. This setting can make the overall structure as small as possible, and provide convenience for installing the PCB board and the connection structure of the PCB board. Electronic products are generally delicate and small. Therefore, the installation environment of the PCB board and the connection structure of the PCB board is not very abundant, and the small connection structure of the PCB board can adapt to more installation environments.
[0033] In the present invention, first, according to the stacking height of the two PCB boards, the screw 21 is rotated to adjust the distance between the two clamps 1. Hold down the two clamps 13 to open one clamp 1 and insert a PCB board. Then loosen the clamp 13, the clamp 1 clamps the PCB board; through the above operation, the other clamp 1 clamps the other PCB board. Through this structural design, two PCB boards can be connected quickly and conveniently. The fixture 1 is designed to clamp a PCB that is longer than the fixture 1, or a PCB that is shorter than the fixture 1, with wide adaptability. The setting of the height adjustment assembly 2 can conveniently adjust the height between the clamps 1 so as to adapt to more PCB boards. In this application, the PCB board does not need to be specially processed, which retains its original structural strength and reduces the manufacturing cost of the PCB.
[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection of the present invention. Within range.
