Mobile socket (conversion plug or row plug)
The safety and performance testing of mobile sockets (such as conversion plugs or strip plugs) involves multiple aspects to ensure compliance with relevant standards (such as IEC 60884, GB 2099, etc.). The following is a detailed test item description for mobile sockets:
1. Sign inspection
Purpose: To ensure clear and accurate labeling on the product for users to use correctly.
Test content:
Check if the markings on the product are clear and durable, including rated voltage, current, power, manufacturer information, certification marks, etc.
The logo should use standard symbols and be not easily worn or detached.
2. Dimensional gauge inspection
Purpose: To ensure that the size of the plug and socket meets the standards and is compatible with other devices that meet the standards.
Test content:
Use standard gauges to check if the dimensions of plugs and sockets comply with regulations.
Check the thickness, width, length of the plug and the size of the socket socket.
3. Anti electric shock protection
Purpose: To prevent users from accidentally coming into contact with live parts during use.
Test content:
Check if the design of the socket can prevent fingers or foreign objects from entering the live socket.
Use standard test indicators (such as IEC 61032 Type B test indicators) to verify protective performance.
4. Grounding resistance test
Purpose: To ensure the effectiveness of the grounding system and prevent the risk of electric shock.
Test content:
Measure the resistance of the grounding terminal to ensure it meets the standard requirements (usually requiring a grounding resistance of no more than 0.1 Ω).
5. Fixed socket structure
Purpose: To ensure that the structural design of fixed sockets is reasonable and can be used safely and reliably.
Test content:
Check the installation method of the socket, the strength of the fixing parts, etc.
Ensure that the socket does not loosen or detach after installation.
6. Structure of plugs and mobile sockets
Purpose: To ensure that the structural design of plugs and mobile sockets is reasonable and can be used safely and reliably.
Test content:
Check if the fit of the shell, internal structure, pins, and sockets meets the standards.
Ensure that the plug and socket are not damaged during the insertion and extraction process.
7. Aging resistance and protection provided by switch housing (IP)
Purpose: To ensure that the product can maintain its protective performance after long-term use.
Test content:
Evaluate the durability of the product through aging tests such as high temperature, humidity, ultraviolet radiation, etc.
Test the protection level (IP rating) of the casing to ensure that it can prevent dust and water from entering.
8. Insulation resistance and electrical strength
Purpose: To ensure that the product has good insulation performance and can withstand a certain voltage without breakdown.
Test content:
Measure the insulation resistance to ensure it meets the standard requirements (usually requiring insulation resistance ≥ 5M Ω).
Conduct high-voltage testing (such as 1500V AC/1 minute) to ensure that the insulation material can withstand the specified voltage.
9. Temperature rise
Purpose: To ensure that the product does not pose a danger due to overheating during normal use.
Test content:
Run the product at rated current and measure whether its temperature rise meets the standard (usually requiring a temperature rise of ≤ 45K).
10. Breaking capacity
Purpose: To ensure that switches or sockets can safely disconnect circuits.
Test content:
Test the breaking capacity of switches or sockets at rated current and voltage.
11. Normal operation
Purpose: To ensure that the product can work reliably under normal usage conditions.
Test content:
Simulate normal usage conditions, perform multiple plug and switch operations (usually requiring at least 5000 times), and check the durability of the product.
12. The force required to unplug the plug
Purpose: To ensure that the plug will not easily come off during normal use and will not be difficult to remove.
Test content:
Measure the force required to pull out the plug, ensuring it is within the specified range (usually requiring a pulling force between 40N-50N).
13. Flexible cords and their connections
Purpose: To ensure the safety and reliability of the flexible cord and its connecting parts.
Test content:
Check whether the specifications, connection methods, and fixing methods of the flexible cords meet the standards.
Conduct a tensile test to ensure that the flexible wire is securely connected.
14. Mechanical strength
Purpose: To ensure that the product can withstand certain mechanical stresses without damage.
Test content:
Evaluate the mechanical strength of the product through impact, pressure, and other tests.
Use an impact hammer (such as 0.5J impact energy) to test the impact resistance of the shell.
15. Heat resistance (ball pressure)
Purpose: To ensure that the product will not deform or be damaged in high temperature environments.
Test content:
Press a ball pressure device of the specified weight onto the sample and evaluate its heat resistance at high temperatures (usually tested at 125 ℃).
16. Screws, current carrying components, and connections
Purpose: To ensure the reliability and safety of screws, current carrying components, and connections.
Test content:
Check whether the tightness of the screws, the material of the current carrying components, and the connection method meet the standards.
Ensure that the current carrying components can withstand the rated current without overheating.
17. Creepage distance, electrical clearance, and sealant penetration distance
Purpose: To ensure that the insulation distance between different potentials of the product is sufficient to prevent arcing or short circuits.
Test content:
Measure the creepage distance, electrical clearance, and distance through sealant to ensure compliance with standards.
18. Insulation materials' resistance to abnormal heat, flame, and electrical traces
Purpose: To ensure that insulation materials do not burn or produce electrical traces under abnormal thermal conditions.
Test content:
Evaluate the flame resistance and electrical trace resistance of insulation materials through hot wire tests (such as 750 ℃), needle flame tests, etc.
19. Rust prevention performance
Purpose: To ensure that metal components do not rust in humid environments.
Test content:
Expose metal components to a humid environment and evaluate their rust prevention performance.
20. Additional test for pins with insulation sheath
Purpose: To ensure that the plug with insulation sheath can remain safe under normal use and abnormal conditions.
Test content:
Conduct additional mechanical, electrical, and heat resistance tests to evaluate its safety.
summary
These testing projects comprehensively cover the safety, durability, mechanical performance, and electrical performance of mobile sockets, ensuring their safety and reliability under normal use and abnormal conditions. Testing is usually conducted in accordance with international standards (such as IEC 60884) or national standards (such as GB 2099) to ensure that the product meets the safety requirements of the global market
