The electrical performance of the waterproof plug includes four aspects: contact resistance, insulation resistance, current and electrical strength. Next, let's analyze the two important electrical properties of the waterproof plug, the contact resistance and the insulation resistance.

       1. Contact resistance of waterproof plug. Contact resistance can be seen everywhere in the electrical performance application of waterproof plugs. A high-quality and durable waterproof plug has the characteristics of low and stable contact resistance. The contact resistance of the waterproof plug fluctuates greatly, ranging from a few milliohms to tens of milliohms, and the parameters depend on the actual performance and characteristics of the waterproof plug.

       2. Insulation resistance of waterproof plugs: Insulation resistance is also an important indicator of the electrical performance of waterproof plugs. Insulation resistance and contact resistance are two vaults for the electrical performance of waterproof plugs, which together determine the resistance performance of waterproof plugs. The specific function of insulation resistance is an important indicator to measure the insulation performance between the contact parts of the waterproof plug and between the contact parts and the shell. . The insulation resistance of waterproof plugs can range from hundreds of megohms to several gigaohms, depending on the actual situation.

       There are many other electrical properties of waterproof plugs, such as electric strength or withstand voltage, current, electromagnetic interference leakage attenuation (usually in the range of 100MHz~10GHz frequency) and so on.

      If the RF coaxial waterproof plug is used, its electrical performance also includes characteristic impedance, insertion loss, reflection coefficient, voltage standing wave ratio (ie VSWR), etc.

      In recent years, with the continuous development of science and technology, the waterproof plug industry has also continued to progress, and the corresponding digital technology has also matured step by step in people's expectations and witnesses. At the same time, in order to transmit high-speed digital pulse signals through waterproof plugs, a series of new waterproof plugs, namely signal waterproof connectors, have appeared in the industry. At the same time, this kind of special waterproof plug 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 delay Special electrical properties such as performance (delay) and time delay (skew).

      There are other electrical properties of waterproof plugs, which will not be explained here. For other basic properties of waterproof plugs, such as mechanical performance or environmental performance, please pay attention to our waterproof plugs.
