1. What is the main function of the circular connector housing?
The shell mainly plays a protective and fixing role, protecting the connector from external environmental influences such as moisture, dust, and impact, and ensuring a secure connection of the cable to prevent cable loosening.
-
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. Does the circular connector housing have shielding function?
Some metal casings provide electromagnetic shielding (EMI/RFI) for high-frequency signal transmission applications to prevent electromagnetic interference.
-
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.
