When we develop a new switching switch and socket, we will do a lot of feasibility experiments to ensure the safety of the switch and socket, which is related to life, not careless.
1. Weldability test
The top of the terminal is immersed in a tin soldering pool at a depth of 1 inch, and the temperature is 230 (+5 C) for 3 (+0.5 seconds).
Be careful:
(1) Welding time should be less than 3 seconds
(2) The welding area should be more than 80%.
2. Welding resistance test
The temperature of welding furnace should be controlled at 260 5 C, the overheating time should be 3 0.5 seconds, the thickness of substrate should be 1.0_ inch, and the temperature of hand welding should be controlled at 320 5 C, and the time should be 3 0.5 seconds.
Requirements: Must satisfy the body without deformation, meet the mechanical and electrical energy.
3. Life Testing
No-load: The operator performs 100,000 no-load tests at 60 times per minute.
Requirement:
(1) Contact resistance should not exceed 200 m_
(2) Other, satisfied with mechanical and electrical properties.
4. Heat Resistance Test
After 96 hours of testing at 85 +2 C, it was measured at normal room temperature for 1 hour.
Requirements: No abnormal appearance, meet the mechanical and electrical performance.
5. Cold Resistance Test
Place it at 40 2 C. After 96 hours of relative humidity in 90-96% environment, the samples were put in normal environment for 1 hour for testing.
Requirements: No abnormal appearance, meet the mechanical and electrical performance.
6. Moisture test
Place it at 40 2 C. After 96 hours of relative humidity in 90-96% environment, the samples were put in normal environment for 1 hour for testing.
Requirements: No abnormal appearance, meet the mechanical and electrical performance.
