Method For Checking Moisture In Terminals Before Using Cold-pressed Pin Crimpers
If there is moisture inside or outside the terminal before using a crimping tool, it will cause corrosion, poor conductivity, and ultimately lead to connection failure. This guide delivers a practical approach to inspecting and drying terminals to guarantee a secure, long-lasting mechanical bond.
Terminal Moisture Inspection
Moisture often traps inside terminal barrels during storage or high-humidity transport. Technicians must perform a visual check under bright lighting or magnification to identify water droplets or dull discoloration.
To properly inspect and prepare components for a contact crimper, follow these three steps:
-
Examine the internal barrel using a bore scope or inspection light for hidden condensation.
-
Check the outer insulation sleeve for moisture film or dampness.
-
Utilize an infrared thermometer to verify the component is at room temperature.
Effective Drying Methods for Components
If moisture is detected, immediate correction is required before utilizing a d sub contact crimper. Wiping the surface is insufficient for the interior barrel.
Air drying or low-temperature ovens provide the best results. The following parameters ensure components dry completely without compromising material integrity:
| Heating Method | Recommended Temperature | Maximum Duration |
|---|---|---|
| Forced Air Dryer | 45°C | 10 Minutes |
| Stabilization Oven | 60°C | 15 Minutes |
Executing the Contact Crimping Process
Once the components register 0% humidity, the assembly can proceed safely. Position the dry terminal into the designated nest of the machinery. Apply consistent pressure until the cycle completes, ensuring the metal deforms correctly around the wire strands.
Proper execution of contact crimping prevents future moisture ingress by creating a gas-tight seal. This strict preparation routine eliminates intermittent signal failures and extends the operational lifespan of the electrical assembly.
