Shell to Shell Conductivity
Electrical FOR: Connector $610Connector shell conductivity is critical for several types of applications. For example, harnesses that contain EMI sensitive circuitry are typically shielded and require good grounding and EMI protection as the signals pass through connectors. Often, this test is used after a thermal/environmental exposure cycle to determine performance after accelerated aging.
For this test, a set of the specimen connectors are mated and a low-voltage, low-current are passed through the shell. The resistance of the shell is measured and reported. This test is only applicable for conductive shell types.Variables that can be adjusted include (but are not limited to):
- Preconditioning
- Current/Voltage
- Environmental Conditions
Procedure
- Mate the specimen connectors.
- Attach one connector to a low voltage low current power source, attached the other to the power source return.
- Measure the voltage drop across the mated connector.
- Report the parameters used and the results.
