USB FTDI Cable IP67 waterproof round connector manufacturers take you to understand the environmental performance of the waterproof round connector
The three major properties of waterproof connectors are mechanical properties, electrical properties, and environmental properties. In the following paragraph, the USB FTDI Cable IP67 waterproof round connector Manufacturers will explain its environmental performance in detail. USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that common environmental properties include temperature resistance, humidity resistance, salt spray resistance, vibration resistance, shock resistance, etc.
1. Temperature resistance: USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that at present, the maximum working temperature of waterproof connectors is 200°C (except for a few high-temperature special-purpose ones), and the minimum temperature is -65°C. When working, the current generates heat at the contact point, resulting in a rise in temperature. Therefore, it is generally believed that the working temperature should be equal to the sum of the ambient temperature and the temperature rise of the contact point. Some specifications clearly stipulate the allowable temperature rise under the rated working current.
2. Salt spray resistance: USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that when working in an environment containing moisture and salt, the metal structure of the connector and the surface treatment layer of the contact may produce galvanic corrosion, thereby affecting the physical and electrical properties.
USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that to test the ability of a connector to withstand this environment, the salt spray test is specified. Hang the connector in the temperature-controlled test box, spray the sodium chloride solution with the specified concentration with compressed air to form a salt fog atmosphere, and the exposure time is specified by the product manual, which is at least 48 hours.
3. Vibration and shock resistance: USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that vibration and shock resistance are important properties of electrical waterproof connectors, especially in special application environments such as aerospace, railway, and road transportation. It is an important index to test the firmness of mechanical structure and electrical contact reliability. It is clearly stipulated in the relevant test methods. The peak acceleration, duration, pulse waveform, and electrical continuity interruption time should be specified in the impact test.
The above is the USB FTDI Cable IP67 waterproof round connector manufacturer's introduction and analysis of the environmental performance of the waterproof round connector, hope it helps you.
