With the advancement and development of electronic technology, the market demand for high-performance electronic equipment has gradually increased. How to ensure the safety of the use of electronic equipment? Rigorous shipping inspection is essential. As an indispensable component in the electronic field, the connector needs to strictly abide by the national standards in any testing process, and pass various tests of the national rules to ensure that the function of the product meets the needs of consumers, so as to achieve long-term and stable use effects. In terms of electrical performance, it mainly includes the following test items:
1. Connector insertion force test
Through the national standard EIA-364-13, verify whether the plug-in force of the connector meets the product specification requirements.
Test method: Insert or pull out the connector at a specified rate, and record the corresponding force value.
2. Connector durability test
Through the standard EIA-364-09, the influence of repeated plugging and unplugging on the connector is evaluated, the plugging and unplugging conditions of the connector in actual use are simulated, and the plugging and unplugging life of the connector is determined.
Test method: Continuously plug and unplug the connector at the specified rate until the specified number of times is reached.
3. Connector insulation resistance test
Refer to the standard EIA-364-21 to verify whether the insulation performance of the connector meets the requirements of the circuit design or whether the resistance value meets the requirements of the relevant technical conditions when subjected to environmental stress such as high temperature and humidity.
Test method: The resistance value presented by applying a voltage to the insulating part of the connector, so that leakage current occurs on the surface or inside of the insulating part.
4. Connector withstand voltage test
Refer to the standard EIA-364-20 to verify whether the connector can work safely at rated voltage and whether it can withstand overpotentials, so as to evaluate whether the connector insulation material or insulation gap is suitable.
Test method: Apply a specified voltage between the connector contact and the contact, and between the contact and the shell for a specified time, and observe whether the sample has breakdown or discharge.
5. Connector contact resistance test
Refer to standard EIA-364-06/EIA-364-23 to verify the resistance value that occurs when current flows through the contact surface of a contact.
Test method: The resistance value is obtained by passing a specified current to the connector and measuring the voltage drop across the connector.
In electronic equipment, although the size of the connector is not large, it is an important part of the electrical and signal interconnection. How do you ensure that the connectors you buy have passed the specification test? You need to choose a reliable connector manufacturer.
