圆形连接器绝缘电阻测试

The development of science and technology in the 21st century tends to be high-precision, and the quality requirements of various industrial circular connector products are also gradually increasing. Many consumers pay attention to the quality and service life of the product itself when purchasing industrial connectors.

The connector also needs to pass a number of tests to ensure that the functions of the verified product meet the needs of consumers, so as to achieve long-term stable use effects, such as insertion force test, vibration test, insulation resistance test, contact resistance test, withstand voltage test, temperature rise test, etc., this time I will introduce the insulation resistance test.

Insulation resistance is one of the important indicators for the production and design of connectors, and it is also the most basic insulation indicator for electrical equipment and electrical circuits. Whether the insulation resistance between the cores of the connector is normal reflects a certain extent whether the connector product is working normally, the following are the precautions and steps:

1. Select the test instrument within the validity period of the calibration, adjust the tester to the insulation test channel, and set the test parameters: voltage, test time, the lower limit of resistance (as shown in the Chuante electronic products, set the parameters according to the drawing requirements: 1000V/ 60s resistance lower limit 100MΩ).

2. Clamp the correct test point. We know that the insulation resistance of the connector mainly depends on the rubber core part inside the connector. If the insulation resistance between each PIN position is tested, the sampling distance between the two nearest A PIN bit is a test point (these two points must be sampled).

3. Press the test button to start the insulation resistance test, wait for the set test time to end, and record the test data.
