Can the pass through connector still be used if it is slightly damaged?

Whether the pass through connector can continue to be used when it is damaged depends strictly on the type and location of the damage. The following are the key judgment points:

1. Damage to the shell/insulator
Fatal damage (unusable):
The shell cracks or breaks, losing structural support or protection level.
The insulation partition has penetrating cracks and carbide burn marks.
The sealing ring is broken or permanently deformed (waterproof/dustproof failure).
Can be temporarily used but requires monitoring (replacement within a specified period):
Slight scratches on the surface of the shell and small gaps in non stress areas (not involving internal sealing).

2. Abnormal contacts
Immediate discontinuation (high-risk):
Pin/socket bending, breakage or end deformation.
There are obvious erosion pits and welding adhesion marks in the contact area.
Extensive peeling of the coating and exposed oxidation of the substrate.
Cautious evaluation (short-term emergency):
The single point coating has slight wear (without exposed substrate), and the functional test is normal (the testing cycle needs to be shortened).

3. Locking mechanism malfunction
Prohibition of use (invalidation warning):
Buckle breakage and thread slippage result in inability to lock.
Abnormal shaking or automatic detachment of the shell during insertion and removal.
Temporary handling (at your own risk):
Auxiliary zip ties/tape reinforcement locking (limited to low voltage signal scenarios and requires full monitoring).

4. Safety operation red line
Absolutely unusable situation:
Any visible damage in high-voltage applications (>50V).
Sealing failure or arc marks in flammable and explosive environments.
Affects grounding continuity (such as damaged grounding spring).
