Some connectors datasheets specify the following:
Metal-to-metal bottoming for maximum EMI shielding under extreme vibration
Reference: Dualok Connectors
I have also encountered the following for a similar component:
Improved shielding resistance due to shell to shell bottoming.
Perhaps the following definition applies:
- to place (something) on or upon a foundation; base
However, this is still unclear to me. What does bottoming mean in this context?
