Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB circuit board technology, specifically to a PCB board with edge protection. Background Technology
[0002] In the field of electronic equipment manufacturing, PCB boards are the core carriers for circuit connections, and their performance directly affects the stability of the entire device. PCB boards are mainly composed of resin and glass fiber composites, with circuits that realize specific functions integrated on the surface. They are widely used in fields such as communications, consumer electronics, and automotive electronics.
[0003] However, in the PCB manufacturing process, large substrates need to be punched to specific dimensions. After punching, the edges are prone to rough burrs due to the material properties. These burrs are easily detached and formed into debris during contact friction during module assembly or vibration during transportation, leading to internal product contamination. If the debris adheres to the circuit solder joints, it may cause a short circuit risk; if it blocks the heat dissipation channel, it will reduce the heat dissipation efficiency of the equipment; in audio equipment, it may also affect the vibration performance of the amplification components, resulting in sound quality distortion. Existing treatment methods mostly rely on manual polishing or post-cleaning, which not only increases production costs and processes, but also makes it difficult to completely eliminate the hidden dangers of burrs. Therefore, we propose a PCB board with edge wrapping. Utility Model Content

The mounting groove 10 of the insulating top plate 5 precisely matches the electronic component 4, providing a stable mounting position for the electronic component 4 to prevent loosening, and also isolating the electronic component 4 from the external environment through insulating material to avoid short circuits caused by contact with foreign objects. The insulating bottom plate 8 isolates the conductive connection between the PCB circuit board 9 and the mounting carrier from the bottom, further enhancing the insulation performance. Simultaneously, the narrow side edging 1 adheres to the side of the PCB circuit board 9, and the long side edging 3 adheres to the front and rear sides. The limiting mounting holes 12 on the top and bottom surfaces of both plates slide to the limiting bosses 7 of the second edging mounting plate 6, completing the initial positioning and ensuring... The protective edging fits tightly against the edge of the circuit board, blocking the path of debris from the punching burrs. After the limiting rotating rod 2 passes through the limiting mounting hole 12, the limiting locking platform 14 at its bottom is embedded in the limiting mounting groove 13 of the first edging mounting plate 11. Rotating the limiting rotating rod 2 causes the limiting locking platform 14 to engage with the limiting mounting groove 13, firmly locking the narrow side edging 1, the long side edging 3 and the insulation protection components to prevent the edging from loosening. The insulating top plate 5, the insulating bottom plate 8 and the narrow side edging 1 and the long side edging 3 form a three-dimensional protective structure: the upper and lower insulation layers ensure the circuit insulation safety, the side edging seals the potential hazards of burrs, and the limiting rotating rod 2, the limiting locking platform 14 and other components ensure the stable connection of each component. It continues to play a protective role during transportation, assembly and use, reducing the risk of failure and reducing maintenance costs.
