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. How can circular connector housings improve the durability of connectors?
The shell can significantly extend the service life of the connector in harsh environments by providing protective measures such as mechanical strength, dust prevention, and waterproofing.
-
3. What are the advantages of plastic shells compared to metal shells?
The plastic casing is lightweight, cost-effective, corrosion-resistant, and suitable for low-power applications and indoor environments. The metal casing provides better strength, impact resistance, and shielding performance.
-
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.
