Broken heating wire is one of the common faults of electric mattresses, and it needs to be handled carefully when repairing to ensure safety and restore the heating function of electric mattresses. Here are the detailed wiring methods:
1. Prepare the tools
Screwdriver. Heating wire repair kit (including compensation wire and heat shrink tubing).
Wire strippers. Heating wire soldering.
Soldering tools (soldering irons, etc.).
Insulating tape. 2. Safety reminders
Power outage: Before maintenance, make sure that the electric mattress is powered off and unplugged.
Inspection: Check whether there are potential safety hazards in other parts of the electric mattress, such as aging insulation, etc.
Protection: Appropriate protective equipment, such as insulating gloves, should be worn during maintenance.
3. Maintenance steps
1. Turn on the electric mattress.
Use a screwdriver to open the outer shell of the mattress or disassemble the suture to locate the broken heating wire.
2. Find the breakpoint.
Carefully inspect the heating wire to find the breaking point. Sometimes breakpoints are not easy to spot and require careful observation.
3. Remove the damaged part.
Use wire strippers to remove damaged heating wires from both sides of the breakpoint, making sure to leave enough length for wiring.
4. Prepare the compensation wire.
According to the length of the heating wire removed, cut the corresponding length of the compensation wire.
5. Wiring operation.
Strip a small piece of bare wire from both ends of the heating wire.
Solder and soldering iron are used to solder the compensation wire to the original heating wire.
Make sure the weld is secure and well connected.
6. Insulation treatment.
Put the heat shrinkable tubing over the weld place, and use the hot air function of a heat gun or electric soldering iron to shrink the heat shrinkable tubing so that it fits snugly against the heating wire to ensure insulation.
If heat shrink tubing is not available, insulating tape can be used to wrap the weld, but it may not be as effective as heat shrink tubing.
7. Testing. Power up the mattress under safe conditions and check if the repaired heating wire is working properly.
Observe the repaired area for abnormal heating or smoke generation.
8. Turn off the electric mattress.
If the test is normal, disconnect the power supply and proceed to the next step.
9. Closing the electric mattress.
Restore the mattress shell or suture to ensure that all parts are in place.
10. Test again.
Repeat the test to ensure that the mattress is still working properly after it is fully assembled.
4. Precautions
Repairing electric heating products involves hot work and electrical knowledge, if you are not sure, please entrust a professional to repair it.
Make sure that the heating wire at the weld is not excessively bent to avoid failure.
After repair, the electric mattress should be avoided from washing with water to prevent short circuit or leakage.
Through the above steps, the broken heating wire can be connected to restore the electric mattress to work. However, it should be emphasized that there are certain risks associated with appliance repairs, and non-professionals should operate with caution. If there is still a problem with the repaired electric mattress, it is recommended to replace it with a new electric mattress to ensure the safety of use.
