Connector safety and performance testing
Are connector products tested? The answer is yes, let Lilutong explain it for everyone. The main purpose of connector testing is to confirm product safety and performance. What aspects of testing are generally used?
Seven major tests of connector safety and performance
First: Connector plug-in force test Purpose: To verify whether the connector plug-in force meets product specifications. Principle: Fully insert or unplug the connector at a prescribed rate, and record the corresponding force value.
Second: Connector durability test Purpose: To evaluate the impact of repeated plugging and unplugging on the connector, and to simulate the plugging and unplugging conditions of the connector in actual use. Principle: Continuously plug and unplug the connector at the specified rate until the specified number of times.
Third: Connector insulation resistance test Purpose: To verify whether the insulation performance of the connector meets the requirements of circuit design or when it is subjected to high temperature, humidity and other environmental stresses, whether its resistance meets the requirements of relevant technical conditions. Principle: Apply voltage to the insulated part of the connector, so that leakage current is generated on the surface or inside of the insulated part and the resistance value appears.
Fourth: the connector withstand voltage test Purpose: to verify whether the connector can work safely under the rated voltage, whether it can withstand the ability of over-potential, so as to assess whether the connector insulation material or insulation gap is appropriate. Principle: Apply a specified voltage between the connector contact piece and the contact piece, between the contact piece and the shell and keep it for a specified time, and observe whether the sample has breakdown or discharge.
Fifth: Connector contact resistance test Purpose: To verify the resistance value generated when current flows through the contact surface of the contact. Principle: The resistance value is obtained by passing a prescribed current through the connector and measuring the voltage drop across the connector.
Sixth: Connector Vibration Test Purpose: To verify the impact of vibration on the performance of electrical connectors and their components. Vibration type: random vibration, sinusoidal vibration.
Seventh: Connector Mechanical Impact Test Purpose: To verify the impact resistance of the connector and its components or to assess whether its structure is firm. Test waveform: half sine wave, square wave.
