The role of the plastic collar between the connector and the thread is actually very important. In short, it has several main functions:
Prevent short circuits: The plastic collar can act as an insulating layer to prevent the metal part of the connector from contacting other metals, thereby avoiding electrical short circuits, especially when used in places with high current or voltage.
Prevent rust: Metal and metal may corrode due to friction or moisture. The plastic collar can separate the metal parts to prevent rust, thereby extending the use time of the device.
Increase stability: The plastic collar can play a certain buffering role between the connector and the thread, reduce the impact of vibration, ensure a stable connection, and not easy to loosen.
Sealing function: It is also waterproof and dustproof, preventing dust and moisture from entering the connector, thereby protecting the internal circuit. This way it can be used outdoors or in humid environments without fear of damage.
Make installation easier: The plastic collar can reduce the resistance of metal friction, making installation smoother, and it can also protect the thread from wear.
Reduce weight: Compared with metal, plastic is much lighter and cheaper, which can help reduce production costs, especially when mass-produced, with a higher cost-effectiveness.
Protect the connector: The plastic collar can also prevent friction between the connector and the thread, avoiding damage.
Improve the appearance: The plastic collar also looks neater, making the connector look cleaner and neater.
In general, although the plastic collar is a small accessory, it can effectively improve the durability and stability of the device, while also simplifying the installation process, so it is useful in many places.
