What are the common performance criteria for waterproof connectors?

Waterproof connector waterproof plug is widely used in LED outdoor, automation equipment, ships, military fields, etc., waterproof flexible cable is in a watery environment can ensure normal and safe power, signal transmission, buy waterproof connectors need to pay attention to what performance? Below together to understand what are the common performance standards for waterproof connectors! Waterproof connector common environmental performance indicators are temperature resistance, moisture resistance, salt spray resistance, vibration resistance, impact resistance, etc.. Temperature resistance. The current operating temperature of the connector is 200oC (except for high-temperature special connectors), the low temperature of -65oC. Therefore, the operating temperature and the ambient temperature is equal to the positive contact temperature, the connector works, the current in the contact point generates heat, resulting in a rise in temperature. Resistant to moisture. The intrusion of moisture seriously affects the connector's insulation properties, metal parts are prone to rust. Certain humidity and heat test conditions are: 95% relative humidity (according to product standards, up to 98%), temperature 4020oC, the test time according to product regulations low for 96h. police station humidity and heat test is more stringent.

Salt spray resistance. When the connector is activated in a humid and salt-containing environment, electrification corrosion occurs on metal structures, plating on the contact surface, thus affecting the physical and electrical properties of the connector. Salt spray test will be suspended in the connector temperature-controlled test chamber, with a prescribed concentration of sodium chloride solution by compressed air spray, the formation of salt spray atmosphere, its exposure time according to the product specification, at least 48h. strong resistance to vibration and shock. Resistance to vibration and shock is an important performance of the electrical connector, is an important indicator to detect the mechanical structure of the electrical connector solidity and electrical contact reliability, in aerospace, railroads and road transportation and other special application environments is particularly important. Other environmental performance. According to the use of requirements, the other environmental performance of the electrical connector sealing (air leakage, liquid pressure), the ability to resist the bad habituation of specific liquids), low air pressure and so on. Waterproof connector is also known as waterproof plug with wire, our company is a ten-year professional waterproof connector manufacturer, the current main ten products are mainly waterproof plug with wire, waterproof plug also has a wire without wire, just some people also call the wire with wire for the waterproof connection line. The above introduction is the waterproof connector common performance standards are, waterproof connector in line with the domestic general waterproof standard, to ensure a reliable connection, with high corrosion resistance and electrical conductivity, can effectively respond to the current caused by the change in temperature rise.
