Q: |
How does interference fit work at the connector interface? |
|
|
A: |
Amerace® connectors are certified to conform to FAA standards, which defines the dimensions necessary. As an example, the FAA provides the following dimensions for primary connectors. |
|
|
|
 |
|
|
|
Plug, Type 1, Class A, Style 2 |
|
|
|
 |
|
|
|
Receptacle, Type 1, Class A, Style 9 |

Therefore:
Maximum interference is 0.051" (0.614 - 0.563) or 1,296mm (15,596 - 14,300)
Minimum interference is 0.021" (0.604 - 0.583) or 0.534mm (15,342 - 14,808)
The interference fit provides a watertight seal at the interface between connectors.
