How to choose a good quality aviation plug

Promulgator : DIHAO Date : 2018-10-09

What are the changes that the air plug brings to us? As we all know, the important role of the air plug as a product accessory to connect the electrical source parts can not be ignored, and its existence also allows us to achieve a lot of functions, which fully proves the importance of the air plug.

Perhaps for the Powercon Plug, we will call it more connector, and from the analysis of these two names, are very intuitive, but also very representative. Because in modern life, there are too many things, especially electronic products. If the electronic products leave the connector, it is equivalent to no effect of the decoration, although it is the main body, connector is only accessories, but the two importance is the same, especially in the realization of mechanical and electrical equipment information transmission time, but also shows the important role of the connector.

Usually, we are concerned about the performance of the Female Powercon Connector, which requires us as a more knowledgeable person can, we need to master some basic knowledge about the aviation plug. In this way, when we choose and apply, we can choose and screen, so that we can find the products we really need, and can play the real role of connectors. It's the essence of serving our lives, and if it doesn't work, first of all, it's a failure.

So the choice of the Powercon Plug is sometimes considered a product choice condition, when we buy Electronic products, we can judge the product by observing its professional connector production quality and production standards, if not timely and effective, especially simple manual testing. We can see that the choice of this electronic product needs to be reconsidered.

All Powercon Plug are inseparable from the current when they are working. This is the danger of fire. Therefore, the aviation plug not only requires to prevent ignition, but also requires that once ignited and ignited, it can extinguish itself in a short time. Attention should be paid to the selection of flame retardant and self extinguishing insulating materials for Powercon Plug.

Contact pressure in Female Powercon Connector is an important index, which directly affects the size of contact resistance and contact pair wear. In most structures, direct measurement of contact pressure is quite difficult. Therefore, the contact pressure is often indirectly calculated by single foot separation force. For circular pinhole contact pairs, a standard pin with a specified weight weight is usually used to test the ability of the negative contact to hold the weight. Generally, the diameter of the standard pin is 5μm below the diameter of the positive contact. The total score is usually two times the sum of the single foot separation force. When the total score exceeds 50N, manual insertion is quite difficult. Of course, for some testing equipment or some special requirements of the occasion, you can choose zero plug-in force air plug, automatic release of air plug and so on.

The mechanical life of Female Powercon Connector refers to the life of the plug, usually 500~1000 times. The contact resistance, insulation resistance and withstand voltage of the aviation plug should not exceed the specified value when the mechanical life is reached. Strictly speaking, mechanical life is a vague concept. Mechanical life should have a certain relationship with time, 10 years used up 500 times and 1 year used up 500 times, obviously the situation is not the same. But there is no more economical and scientific way to measure it.
