Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a protective mechanism for circuit boards. Background Technology

[0002] A circuit board, also known as a printed circuit board or printed circuit board, is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the substrate. It features high wiring density, light weight, thinness, and good bending properties.

[0003] Existing circuit boards are usually stacked during transportation. Since circuit boards are very delicate components, they are inevitably subject to bumps and external impacts during transportation, making them very easy to be damaged. Based on this, we propose a protective mechanism for circuit boards. Utility Model Content

[0004] The purpose of this invention is to provide a protective mechanism for circuit boards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for circuit boards, comprising: a protective box and a circuit board body;

[0006] The protective mechanism includes a sliding groove, a mounting block, a placement groove, a clamping plate, and a first spring. The sliding groove is provided at the bottom of the protective box. The mounting block is slidably connected to the inner wall of the sliding groove. The placement groove is provided at the upper end of the mounting block. Two clamping plates are symmetrically slidably connected to the inner wall of the placement groove. Multiple first springs are fixedly connected to the inner wall of the placement groove. The other ends of the multiple first springs are all fixedly connected to the clamping plates.

[0007] Preferably, rubber pads are fixedly connected to the sidewalls of the two clamping plates that are close to each other.

[0008] Preferably, a slide rod is fixedly connected to the inner wall of the slide groove, the side wall of the slide rod is slidably connected to the mounting block, and two damping spring dampers are symmetrically sleeved on the side wall of the slide rod. The two ends of the damping spring dampers are fixedly connected to the inner wall of the slide groove and the side wall of the mounting block, respectively.

[0009] Preferably, a limiting mechanism is installed on the clamping plate. The limiting mechanism includes a groove formed on the upper end of one of the clamping plates, a limiting rod slidably connected to the inner wall of the groove, and a slot that cooperates with the limiting rod on the upper end of the other clamping plate. A second spring is fixedly connected to the bottom of the groove, and the upper end of the second spring is fixedly connected to the lower end of the limiting rod.

[0010] Preferably, a cover plate is rotatably connected to the upper end of the protective box, and the other end of the cover plate is fixedly connected to the upper end of the protective box via a threaded rod.

[0011] Preferably, the protective box has multiple ventilation holes symmetrically opened on its side wall.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The protective mechanism for this type of circuit board, by setting up the protective mechanism, by placing the circuit board body in the protective box, and using clamps to clamp and fix the circuit board body, and laying rubber pads, can prevent the circuit board body from being damaged by external impact during transportation.

[0014] (2) The protective mechanism for this type of circuit board is equipped with a damping spring shock absorber. When the circuit board is bumped during transportation, the damping spring shock absorber can effectively reduce the shock by extending and retracting, thus preventing the circuit board body from being damaged by the bumps.

[0015] (3) The protective mechanism for this type of circuit board has ventilation holes. Since the protective box is relatively sealed, the ventilation holes can effectively ventilate and avoid the circuit board body from being damaged due to excessively high internal temperature.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a protective mechanism for circuit boards, comprising: a protective box 1 and a circuit board body 2;

[0023] The protective mechanism includes a slide 3, a mounting block 4, a placement groove 5, a clamping plate 6, and a first spring 7. The bottom of the protective box 1 has a slide 3. The mounting block 4 is slidably connected to the inner wall of the slide 3. The upper end of the mounting block 4 has a placement groove 5. Two clamping plates 6 are symmetrically slidably connected to the inner wall of the placement groove 5. Multiple first springs 7 are fixedly connected to the inner wall of the placement groove 5. The other end of each of the multiple first springs 7 is fixedly connected to the clamping plate 6.

[0024] The two clamps 6 are fixedly connected to each other on their side walls with rubber pads 8.

[0025] A slide rod 9 is fixedly connected to the inner wall of the slide groove 3. The side wall of the slide rod 9 is slidably connected to the mounting block 4. Two damping spring dampers 10 are symmetrically sleeved on the side wall of the slide rod 9. The two ends of the damping spring dampers 10 are fixedly connected to the inner wall of the slide groove 3 and the side wall of the mounting block 4, respectively.

[0026] A limiting mechanism is installed on the clamping plate 6. The limiting mechanism includes a groove 11 opened on the upper end of one of the clamping plates 6. A limiting rod 12 is slidably connected to the inner wall of the groove 11. A slot 13 that cooperates with the limiting rod 12 is opened on the upper end of the other clamping plate 6. A second spring 14 is fixedly connected to the bottom of the groove 11. The upper end of the second spring 14 is fixedly connected to the lower end of the limiting rod 12.

[0027] The upper end of the protective box 1 is rotatably connected to a cover plate 15, and the other end of the cover plate 15 is fixedly connected to the upper end of the protective box 1 through a threaded rod 16.

[0028] The protective box 1 has multiple ventilation holes 17 symmetrically opened on its side wall.

[0029] In this invention, the circuit board body 2 is inserted between two clamping plates 6. The clamping plates 6 clamp and fix the circuit board body 2 under the action of the first spring 7, thereby ensuring the stability of the position of the circuit board body 2 and preventing the circuit board body 2 from being damaged by external impact during transportation.

[0030] If bumps occur during transportation, the mounting block 4 will compress the damping spring damper 10, causing the damping spring damper 10 to extend and retract, reducing the vibration experienced by the mounting block 4, thereby preventing the circuit board body 2 from being damaged by vibration.

[0031] Since the protective box 1 is relatively sealed, the ventilation hole 17 can effectively ventilate, avoiding excessively high internal temperature of the protective box 1 that could damage the circuit board body 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
