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. Can the circular connector housing be customized?
Yes, many manufacturers offer customized shell services, including customized materials, colors, sizes, and specific environmental adaptability requirements to meet specific application needs.
-
4. How does the circular connector housing ensure the mechanical stress release of the cable?
The casing is usually equipped with cable clamps or stress relief devices, which firmly fix the cable to prevent mechanical stress caused by pulling or bending from being transmitted to the electrical connection part of the connector, thereby extending the life of the connector.
