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 is a quick disconnect housing?
Quick disconnect housing is a type of housing designed for quick connection and disconnection, typically used in applications that require frequent plugging or quick maintenance, such as military, aviation, and industrial automation fields.
-
3. How to choose the cable entry for the circular connector housing?
The size of the cable entry for the casing should be selected based on the diameter of the cable used, ensuring that the cable can be tightly clamped after passing through the entry to prevent tension from affecting the internal connection points of the connector.
-
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.
