Three basic properties of electronic connectors

We know that the basic performance of electronic connectors include three categories, that is, mechanical properties, electrical properties and environmental performance, the basic performance of the connector directly determines whether or not it can be used normally, then we briefly look at the three major properties.
　　1, mechanical properties. In terms of its connection function, the insertion and extraction force is very important mechanical properties. Insertion and extraction force including insertion force and extraction force two parts, because the role of different, so the two requirements are not the same, from the user's point of view, the insertion force is smaller, but the separation force can not be too small, so as not to affect the contact reliability.
　　2, electrical performance. Electrical performance includes three major parts, namely, insulation resistance, electrical strength and contact resistance.
　　One of the insulation resistance is an important indicator of the insulation performance between the contacts, contacts and shell. The contact resistance is required to be low and stable. Generally ranging from a few milliohms to tens of milliohms. Electrical strength is also the ability of the connector to withstand the voltage.
　　3, environmental performance. The more common environmental performance of temperature resistance, moisture resistance, salt spray resistance, vibration resistance and shock resistance. Most of the connector temperature resistance temperature of 200 ℃ -65 ℃. Humidity has a great impact on the performance of the connector, may lead to insulation degradation, some good point of the connector moisture can reach 90% to 95%, or even 98%. Salt spray resistance is the connector is used in the environment with salt and moisture, its performance is not affected too much, the general requirements of salt spray test 48 hours.

　　Vibration and shock resistance is also a very important connector performance, especially in special environments is used, this function is very important.

　　The three basic properties of electronic connectors are introduced here, in order to ensure the safety and reliability of the use, we should purchase products with qualified performance.
