The electrical performance of the waterproof connector includes four aspects: contact resistance, insulation resistance, current and electrical strength. Next, let's analyze the two important electrical properties of the waterproof connector, the contact resistance and the insulation resistance.
1. The contact resistance of the waterproof connector. Contact resistance can be seen everywhere in the electrical performance applications of waterproof connectors. The contact resistance of a high-quality and durable waterproof connector meets the characteristics of low and stable applications. The contact resistance of the waterproof connector fluctuates greatly, ranging from a few milliohms to tens of milliohms. The available parameters depend on the actual performance and characteristics of the waterproof connector.
2. Insulation resistance of waterproof connectors: Insulation resistance is also an important indicator of the electrical performance of waterproof connectors. Insulation resistance and contact resistance are the two vaults of electrical performance of waterproof connectors. Together, they determine the resistance performance of waterproof connectors. The specific function of the insulation resistance is to measure the important index of the insulation performance between the various contacts of the waterproof connector and between the contact and the shell. Its value must be within the range of industry regulations, otherwise the waterproof connector will not be normal or perfect. To use. The insulation resistance of the waterproof connector can range from hundreds of megaohms to several thousand megaohms, depending on the actual situation.
There are many other electrical properties of waterproof connectors, such as electrical strength or withstand voltage, current, electromagnetic interference leakage attenuation (the range is usually between 100MHz and 10GHz) and so on.
If you are using a radio frequency coaxial waterproof connector, its electrical performance also includes characteristic impedance, insertion loss, reflection coefficient, voltage standing wave ratio (ie VSWR), etc.
In recent years, science and technology have continued to develop, and the waterproof connector industry has also continued to advance. The corresponding digital technology has matured step by step in people's expectations and witnesses. At the same time, in order to transmit high-speed digital pulse signals to the waterproof connector, a new type of waterproof connector appeared in the industry, namely, signal waterproof. At the same time, this kind of special waterproof connector also has great advantages and breakthroughs in electrical performance. For example, in addition to characteristic impedance, its electrical performance also has some new electrical indicators, such as crosstalk electrical performance (crosstalk), transmission Special electrical properties such as delay and skew.
There are other electrical properties of the waterproof connector, which will not be explained here. For other basic properties of the waterproof connector such as mechanical performance or environmental performance, please pay attention to our E-WEICHAT waterproof connector
