Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to an ultra-high transparency transparent screen circuit board. Background Technology

[0002] Ultra-high transparency screen is a display technology product with excellent optical performance. When turned off, it can achieve a light transmittance almost similar to that of ordinary transparent glass, allowing viewers to clearly see objects behind the screen. Visually, the screen is almost imperceptible, and it can present clear and vivid images with sufficiently bright highlights and sufficiently deep shadows, giving the image a strong sense of depth and three-dimensionality.

[0003] When using ultra-high transparency screens, circuit boards are often used. Circuit boards provide precise electrical connections for various electronic components in the transparent screen, such as driver chips and sensors.

[0004] In daily work, it has been found that existing ultra-high transparency circuit boards are fixed to the equipment with bolts during use. Once the equipment is vibrated, the vibration energy is transmitted to the circuit board without buffering. This causes the delicate internal circuits and components to vibrate, and over time, the circuit board is prone to damage such as loose solder joints, broken circuits, and detached components, affecting the normal operation of the circuit board. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where vibrations from equipment are directly transmitted to the circuit board, which can easily damage the circuit board over time. Therefore, this invention proposes an ultra-high transparency transparent screen circuit board.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an ultra-high transparency circuit board, comprising a circuit board body, a protective device provided on the surface of the circuit board body, the protective device comprising two frames, the two frames respectively located on both sides of the circuit board body, the frames being U-shaped, the surface of the circuit board body having multiple reserved holes, the inner walls of the upper and lower sides of the frames being threaded with connecting rods, the connecting rods being inserted into the reserved holes, the surface of the connecting rods being provided with buffer parts for buffering the circuit board body, and the side of the frame away from the circuit board body being provided with an mounting part. Through the above components, in use, the circuit board body can first be placed in the two frames, and then the connecting rods are threadedly connected to the frames, so that the connecting rods are respectively inserted into the corresponding reserved holes. The buffer parts are in contact with the surface of the circuit board body, and can buffer and protect against vibration, effectively absorbing vibration energy, greatly reducing problems such as loose solder joints, broken circuits, and component desoldering caused by vibration impact, and extending the service life of the circuit board.

[0007] Preferably, the connecting rod includes a threaded rod and a plug rod, the plug rod is fixed on the surface of the threaded rod, the threaded rod is threadedly connected to the inner wall of the frame, and the diameter of the plug rod is smaller than the diameter of the reserved hole.

[0008] Preferably, the upper end of the threaded rod has a cross groove.

[0009] Preferably, the buffer part includes a movable ring that is slidably connected to the inner wall of the insert rod in the connecting rod. A buffer spring is fixedly connected to the side of the movable ring corresponding to the inner wall of the insert rod. There are four buffer springs. When the above-mentioned components are subjected to vibration, the buffer springs and the movable ring can limit the circuit board body and reduce damage to the circuit board body.

[0010] Preferably, a gasket is fixedly connected to the surface of the movable ring, and a protective sleeve is fixedly connected to the outer surface of the insertion rod. Through the above components, the insertion rod and the protective sleeve are inserted into the reserved hole, which can limit and protect the circuit board body. At the same time, the movable ring and the gasket fit together with the circuit board body, which can play a protective role.

[0011] Preferably, both the gasket and the sheath are made of rubber.

[0012] Preferably, the mounting part includes two mounting seats fixed to one side surface of the frame. Screws are inserted into the inner wall of the mounting seats. Through the above components, the mounting seats can be connected to the equipment with the screws, thereby installing the circuit board body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a protective device, the circuit board body can be restricted within two frames by multiple connecting rods and a buffer part. When the equipment vibrates, the buffer part can move within the connecting rods, effectively absorbing vibration energy and greatly reducing problems such as loose solder joints, broken circuits, and component desoldering caused by vibration impact, thus extending the service life of the circuit board.

[0015] 2. In this utility model, by setting up an installation part and using the mounting base and screws to cooperate, the circuit board body can be connected and fixed to the equipment.

[0016] 3. In this utility model, the insertion rod and the protective sleeve are inserted into the reserved hole, which not only realizes the precise positioning of the circuit board body in the frame and reduces its displacement during daily use, but also the rubber protective sleeve can reduce the hard friction between the insertion rod and the reserved hole. At the same time, the gasket also reduces the hard friction between the moving ring and the circuit board body, thus protecting the circuit board body and reducing the risk of physical damage.
