Precautions for daily use of J1939 splitter Y cable
For the daily use of J1939 splitter Y cable, the following precautions should be followed to ensure communication stability and equipment safety:
1、 Operating standards
Plug and unplug management
When plugging or unplugging, pinch the connector housing to avoid pulling or pulling the cable body directly.
It is strictly prohibited to plug and unplug with power (unless using hot swappable splitters) to prevent equipment damage from instantaneous high voltage.
Long term unused interfaces should be equipped with dust covers to prevent foreign objects from entering.
Cleaning requirements
Regularly wipe the surface of the joint with a dry soft cloth to avoid oil stains or metal debris affecting contact.
Do not use sharp tools to clean the interface to prevent scratching the golden fingers.
2、 Environmental control
Temperature and humidity management
Ensure that the working temperature of the cable is within the specified range, and keep away from heat sources in high-temperature environments.
When the humidity is high, ventilation should be strengthened to avoid insulation degradation caused by condensation water.
Vibration and mechanical stress
Reserve appropriate slack when fixing cables to avoid fatigue fracture caused by equipment vibration.
Avoid cables being subjected to heavy pressure or frequent bending.
3、 Connection status maintenance
contact reliability
Check if the fastening screws of the joints are loose every month and reinforce them with a torque wrench according to the standard torque.
Regularly measure the resistance of the grounding wire to ensure effective grounding of the shielding layer to suppress interference.
Signal integrity
Regularly monitor the differential signal waveform using an oscilloscope. If signal distortion is detected, immediately investigate whether the cable is interfered by high-voltage lines or motors.
4、 Storage and installation
Storage conditions
Unused cables should be coiled and stored to avoid tangling, and the storage environment should be dry and ventilated.
Avoid storing together with acidic or alkaline substances to prevent corrosion of the insulation layer.
Installation specifications
Keep a distance away from heat sources and interference sources such as engine blocks and high-voltage wiring harnesses.
Use specialized clamps to secure and avoid direct contact with sharp metal edges.
