1. What is a circular connector housing?
A circular connector housing is a structural component used to protect internal connectors and cables, typically providing mechanical support and environmental sealing to prevent dust, water, chemicals, or physical damage.
-
2. What are the common materials for circular connector housings?
Common shell materials include metal (such as aluminum, stainless steel) and plastic. Metal casings typically have better shielding and corrosion resistance, while plastic casings are lightweight and suitable for applications that do not require shielding.
-
3. What are the advantages of circular connector housings in outdoor applications?
The shell provides protection level, weather resistance, and corrosion resistance, ensuring that the connector operates stably for a long time in humid, extreme temperature, and outdoor environments.
-
4. How to maintain the circular connector housing?
Regularly inspect the surface of the casing for wear or corrosion, ensuring that the seals are intact and kept clean. If necessary, aging or damaged casings and seals should be replaced in a timely manner.
