1. 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.
-
2. How to ensure compatibility between the casing and internal connectors?
When selecting a casing, it is necessary to confirm its size, thread specifications, installation method, and compatibility with internal connectors to ensure that the casing can be fully adapted.
-
3. 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.
-
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.
