[0002] A circuit board is a core component in electronic devices for supporting and connecting electronic components, and the circuit board needs to be clamped by a fixture during processes such as drilling, welding and assembling, and testing and detecting to prevent the circuit board from shaking.

[0003] In current circuit board fixtures, generally, the circuit board is clamped by an upper clamping plate and a lower clamping plate. Due to the interference of the upper clamping plate, the circuit board generally needs to extend horizontally or in the front-back direction between the clamping plates and then be clamped. During the process of the circuit board extending between the clamping plates, the staff also needs to pay attention to whether the circuit board rubs and scratches against the clamping plates, which is rather cumbersome. Therefore, it needs to be improved so that the circuit board can be placed vertically and avoid interference with the upper clamping plate, facilitating clamping and locking.

[0029] Refer to Figures 1 - 5, according to an embodiment of a circuit board fixture of the present utility model, it includes a clamping assembly. The clamping assembly includes a base body 11. A chute 12 is provided inside the base body 11. The chute 12 runs through from front to back, and a through groove 13 is provided on the side surface of the chute 12. An installation seat 14 is provided in the through groove 13, and an upper pressing plate 15 is slidably connected left and right inside the installation seat 14. A lower pressing plate 16 is provided on the side surface of the base body 11 where the through groove 13 is opened. It further includes a pressing mechanism for controlling the position of the upper pressing plate 15.

[0030] In addition, there are four clamping assemblies arranged in a matrix distribution, and the left and right clamping assemblies are symmetrically arranged so that the upper pressing plate 15 and the lower pressing plate 16 are arranged opposite to each other. The base bodies 11 inside each clamping assembly are connected by a bottom plate 17.

[0031] The upper pressing plate 15 and the lower pressing plate 16 above and below are used to clamp the circuit board. In this embodiment, the installation seat 14 is slidably connected up and down in the through groove 13. The pressing mechanism includes a spring plate 18 arranged on the upper side of the upper pressing plate 15. A convex platform is also provided on the side surface of the installation seat 14, and the spring plate 18 and the convex platform are connected by a horizontally arranged first spring.

[0032] An inclined chamfer is formed between the side surface of the chute 12 far from the through groove 13 and the upper side surface of the base body 11 to form a first inclined surface 91. A second inclined surface 92 that can cooperate with the first inclined surface is provided on the upper pressing plate 15.

[0033] Before clamping the circuit board, the upper pressing plate 15 does not extend outside the through groove 13, and at this time, the staff can place the circuit board on the lower pressing plate 16 from top to bottom. Then the staff makes the installation seat 14 move downward. During the downward movement of the installation seat 14, the upper pressing plate 15 will gradually extend outside the through groove 13 under the cooperation of the first inclined surface 91 and the second inclined surface 92. Then, after the upper pressing plate 15 abuts against the vertical side surface of the chute 12, it maintains its relative position with the installation seat 14. After that, the protruding upper pressing plate 15 can press on the circuit board and clamp the circuit board between the upper pressing plate 15 and the lower pressing plate 16.

[0034] Similarly, when it is necessary to unlock the circuit board, the installation seat 14 moves upward. During this process, under the action of the first spring, the upper pressing plate 15 will retract inward into the through groove 13, and then the staff can take out the circuit board.

[0035] In the above process, in order to lock the position of the mounting base 14 after it descends and the upper pressing plate 15 presses on the circuit board, the mounting bases 14 in the front and rear clamping components are connected by a connecting rod 19. A locking member is provided on the bottom plate 17 arranged in the front and rear direction for connecting the front and rear clamping components. The locking member includes a sliding seat 20. A hook plate 21 acting on the connecting rod 19 is slidably connected left and right in the sliding seat 20, and the hook plate 21 is connected to the inner wall of the sliding seat 20 by a third spring.

[0036] During the downward movement of the mounting base 14, the connecting rod 19 will first cause the hook plate 21 to slide through the third inclined surface in the hook plate 21. After that, the hook plate 21 can rebound under the action of the third spring to hook on the upper edge of the connecting rod 19, so as to lock the up and down positions of the connecting rod 19 and the mounting base 14 at this time, and clamp the circuit board.

[0037] In order to facilitate unlocking the connecting rod 19, two locking members are provided on each bottom plate 17 extending in the front and rear direction, and the backs of the hook plates 21 in the two locking members distributed in the front and rear are connected by a pull handle 23.

[0038] In addition, a control board 22 is provided on the connecting rod 19. Two control boards 22 are provided on each connecting rod 19, and the two control boards 22 are distributed in the front and rear.

[0039] That is, after the user places the circuit board on the lower pressing plate 16, the connecting rod 19 and the mounting base 14 can be pressed down through the control board 22. During the process of pressing down the mounting base 14, the upper pressing plate 15 will slide inwards until it presses on the circuit board. At this time, the hook plate 21 can lock the up and down positions of the connecting rod 19 and the mounting base 14, and the circuit board will be locked at this time.

[0040] When it is necessary to unlock the circuit board, the staff pulls the pull handle 23 outwards. At this time, the mounting base 14 is unlocked and will move upwards under the action of the second spring. During this process, the upper pressing plate 15 moves outwards under the action of the first spring, the first inclined surface 91 and the second inclined surface 92 until it enters the through groove 13, so as to avoid interfering with the circuit board being taken away upwards.

[0041] In the second embodiment of the circuit board fixture, in order to make the placement position of the circuit board accurate, a baffle 24 capable of abutting against the edge of the circuit board is provided on the side surface of the upper pressing plate 15.

[0042] When the mounting base 14 is at the uppermost side and the circuit board is placed on the lower pressing plate 16, the edge of the circuit board is attached to the side surface of the baffle 24. When the mounting base 14 sinks so that the upper pressing plate 15 presses on the circuit board, the baffle 24 will descend to the lower side of the lower pressing plate 16 to avoid affecting the operation of the staff on the locked circuit board.

[0043] In addition, it should be noted that flexible layers are provided on the side surfaces of the upper pressing plate 15 and the lower pressing plate 16 to avoid damaging the circuit board.

[0044] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
