The electrical performance of the basic performance of the waterproof plug
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's contact resistance and insulation resistance.
1. Contact resistance of waterproof plug. Contact resistance can be seen everywhere in the electrical performance applications of waterproof plugs. The contact resistance of a high-quality and durable waterproof plug meets the characteristics of low and stable applications. The contact resistance of the waterproof plug fluctuates greatly, ranging from a few milliohms to tens of milliohms. The available 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 the two vaults of electrical performance of waterproof plugs. Together, they determine the resistance performance of waterproof plugs. The specific function of the insulation resistance is to measure the important index of the insulation performance between the various contacts of the waterproof plug and between the contact and the shell. Its value must be within the range of industry regulations, otherwise the waterproof plug will not work normally or can not be used perfectly. . The insulation resistance of the waterproof plug can range from hundreds of megohms to thousands of megohms, depending on the actual situation.
There are many other electrical properties of waterproof plugs, 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 plug, 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 plug industry has also continued to advance. 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 with 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 lag (skew).
Waterproof plugs also have other electrical properties, which are not explained here. For other basic properties of waterproof plugs, such as mechanical properties or environmental performance, please pay attention to our waterproof plugs.
