Description

Technical Field

[0001] This utility model relates to the technical field of circuit boards, specifically to an anti-electric shock circuit board. Background Technology

[0002] There are many types of circuit boards, such as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, and printed circuit boards. Circuit boards make circuits miniaturized, integrated, and intuitive, and play a very important role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] The existing publicly available technology, disclosed in CN216600211U, discloses a pressure-resistant and electric shock-proof circuit board, including a main board. Four side blocks with pressure-resistant functions are fixedly connected to the four corners of the main board. A connecting plate is fixedly connected to one side of the main board. A gathering mechanism is provided on the top of the connecting plate. An insulating cloth is rotatably connected inside the gathering mechanism. A movable block is fixedly connected to one end of the insulating cloth. A rotating mechanism for easy engagement is provided inside the movable block. A locking mechanism is connected to the bottom of the rotating mechanism, and one end of the locking mechanism is connected to the main board. In this pressure-resistant and electric shock-proof circuit board, the gathering mechanism on one side of the main board can store the insulating cloth. When the main board needs to be disassembled and repaired, the insulating cloth can be pulled out through the movable block to cover the surface of the circuit board. This not only provides electric shock protection but also prevents dust accumulation on the main board surface, thus protecting the circuit board.

[0004] However, the aforementioned patent still has certain drawbacks in its use: although it can protect the circuit board from electric shock by using insulating cloth, the use and fixing of the insulating cloth will cause it to move from the components on the surface of the circuit board and be fixed from the slot below it. This makes it easy for the insulating cloth to cause wear and damage to the surface components when it moves, which in turn leads to damage to the circuit board. Moreover, when it is rolled up, the moving block also passes over the components, further increasing the probability of circuit board damage. In addition, although it uses side blocks to distribute pressure, the pressure will still act on the edges and corners of the circuit board. Over time, this can easily cause the edges and corners to become weak and crack, affecting the subsequent use of the circuit board. Overall, the use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, an anti-electric shock circuit board is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, an anti-electric shock circuit board according to an embodiment of the present utility model includes a circuit board body 1 and a support seat 14. The support seats 14 are symmetrically installed on both sides of the circuit board body 1. A support rod 13 is fixedly welded to the middle position of the bottom surface of the support seat 14. A force-bearing plate 5 is welded to the top position of the support rod 13. A fixing groove 15 is formed below the force-bearing plate 5 at the middle position of one side surface of the support seat 14. The fixing groove 15 is engaged with the circuit board body 1.

[0032] In one embodiment, several sets of fixing plates 2 are symmetrically installed on the top four sides of the circuit board body 1. Guide rods 4 are fixedly installed on the top of each pair of fixing plates 2. Sliding cylinders 11 are slidably connected to the outer periphery of the guide rods 4. Connecting strips 10 are fixedly installed between the sliding cylinders 11. Insulating cloth 9 is installed at one end of the connecting strips 10. A storage box 8 is fixedly installed between the fixing plates 2 on one side. A winding drum 7 is rotatably connected inside the storage box 8. Torsion springs 16 are connected to both ends of the winding drum 7. The outer periphery of the winding drum 7 is connected to the other end of the insulating cloth 9.

[0033] In one embodiment, a rod 6 is slidably connected to the top surface of the slide cylinder 11, and a return spring 12 is fixedly installed between the outer periphery of the rod 6 and the surface of the slide cylinder 11. The rod 6 is provided to fix the slide cylinder 11 after it has been moved.

[0034] In one embodiment, a positioning hole 3 is provided on one side of the guide rod 4 away from the storage box 8, and the positioning hole 3 facilitates the fixed use of the slide cylinder 11.

[0035] In one embodiment, the size of the positioning hole 3 is the same as the size of the insertion rod 6. The size setting ensures that the insertion rod 6 can smoothly fix the slide cylinder 11, which is convenient for subsequent use.

[0036] In one embodiment, the force-bearing plate 5 and the fixing groove 15 are suspended structures. The suspension structure is designed to ensure that the force-bearing plate 5 does not transmit pressure to the fixing groove 15 when it is under force, thereby avoiding squeezing damage to the internal circuit board.

[0037] In one embodiment, the area of ​​the force-bearing plate 5 is larger than the surface area of ​​the fixing groove 15. The size between the force-bearing plate 5 and the fixing groove 15 is set so that external pressure objects can directly contact the force-bearing plate 5, while avoiding contact with the fixing groove 15, thus preventing the circuit board from cracking.

[0038] In one embodiment, the force plate 5, the support rod 13, and the bearing seat 14 are all made of metal. The metal material ensures the strength of the structure and, in order to prevent electric shock, an insulating coating can be applied to the surface of the structure.

[0039] Working principle: In actual use, the circuit board body 1 can be supported by the fixing groove 15 on the surface of the bearing seat 14. When it needs to be squeezed or pressured, the force plate 5 on the top of the bearing seat 14 can come into contact with the pressure object, and then the pressure generated is applied to the bearing seat 14 through the support rod 13, avoiding the pressure transmission to the circuit board, thereby improving the protection effect of the circuit board and effectively preventing the damage to the edges and corners of the circuit board caused by pressure transmission. Then, when it is necessary to prevent electric shock during operation, the insulating cloth 9 can be pulled out by pulling the connecting strip 10 to cover the components on the surface of the circuit board, thereby achieving the purpose of preventing electric shock. The insulating cloth 9 and the connecting strip 10 used to pull it are both restricted by the guide rod 4 mounted above, thus effectively avoiding the contact between the connecting strip 10 and the insulating cloth 9 and the surface structure of the circuit board, preventing collision and friction damage, reducing damage to the circuit board during use, and improving the use effect of the device. The device as a whole has the advantages of stronger pressure resistance, insulation and anti-damage, and compression and anti-breakage.
