In the traditional fastener assembly method, the metal plate shell encloses many individual fixed together components. These components are fixed by different types of accumulators and must be safe and vibration resistant.
The choice of fasteners and the use of tools will also affect other design criteria, such as the speed of assembly, cost, function, and aesthetics—even "designed for disassembly, which requires housing maintenance, and when the product's life cycle is over." Disassembly. All these design requirements will affect the final product, and will affect the choice of fasteners and tools.
Based on function and aesthetics, traditional fasteners, bolts and hinges are often evaluated and selected. Over the years, these products have been enhanced from simple basic designs to products with multiple built-in features and functions. Although the products have improved, the installation methods of these products have not changed significantly. They still rely mainly on screwing, beaconing, riveting or simple clamping as options. Screw installation is a common method for connecting metal panels. The obvious advantage of screw bayonet products is that the screws can be removed and inserted at any time. However, there is a disadvantage that the screw installation requires a relatively long time to tighten the screw, and it also requires the installation of accessories such as nuts, bolts and washers. Another important problem is the possibility of losing installation accessories. For example, the installation accessories loosen over time and fall into the chassis, damaging the precision parts of the sensor. In addition, it is difficult to ensure the airtightness required for screw assembly through simple visual inspection.
