Hardware, Fasteners, Accessories

1. Hardware Overview

‌Structural parts and support parts‌

Includes basic physical structural parts such as equipment housing, brackets, and guide rails, which are used to protect internal circuits or provide installation frames. For example, metal/plastic housings can shield electromagnetic interference, and PCB board support frames are used to fix the position of circuit boards.

‌Installation tools and auxiliary equipment‌

Involves welding tools (such as soldering irons), PCB punching equipment, etc., which are used for physical assembly and debugging of components. For example, soldering irons are used to solder discrete components or connect wires.

2. Fasteners Overview

‌Mechanical connection elements‌

Includes standard parts such as screws, nuts, and washers, which are used to fix components in electronic devices. For example, screws are used to fix heat sinks and chips, and spring washers can prevent loosening caused by vibration.

‌Special fixing devices‌

Such as non-threaded fixing solutions such as buckles, cable ties, and adhesives. For example, nylon cable ties are used for cable management, and thermal conductive adhesives are used to bond heat sinks and power devices.

3. Accessories Overview

‌Connection accessories‌

Includes interface components such as plugs, sockets, and pin headers, which are used for detachable connections between circuits. For example, USB interface modules are standardized connection accessories, and female headers are used to connect expansion boards to motherboards.

‌Functional expansion accessories‌

Such as auxiliary modules that enhance device functions, such as cooling fans, LED indicators, and buzzers. For example, cooling fans reduce the temperature of high-power components through active heat dissipation, and LED lights are used for status indication.

‌Protection and maintenance accessories‌

Includes dust screens, anti-static wrist straps, fuses, etc. For example, fuses are used for overcurrent protection, and anti-static accessories can prevent components from being damaged by static electricity breakdown.
