Any electrical connector in the work are inseparable from the current, which there is the risk of fire. Therefore, the electrical connector is not only required to prevent ignition, but also requires the ignition and fire, in a short time to destroy. In the selection should pay attention to choose to use flame retardant, self-extinguishing insulation of the electrical connector.

Contact contact pressure in the electrical connector is an important indicator that directly affects the size of the contact resistance and the amount of wear on the contact pair. In most structures, it is quite difficult to measure the contact pressure directly. Therefore, the contact pressure is often measured indirectly by the single foot separation force. For round pinhole pairs, the ability to check the weight of a female contact with a standard pin with a specified weight is generally measured. The diameter of the standard pin is usually 5 μm from the lower limit of the male contact. The total separation force is generally one-foot separation force on the line and twice. The total separation force of more than 50N, with artificial plug has been quite difficult. Of course, for some test equipment or some special requirements of the occasion, you can use zero plug the electrical connector, automatically cut off the electrical connector and so on.

Electrical connector mechanical life refers to the plug life, usually defined as 500 to 1000 times. When the mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the electrical connector shall not exceed the specified value. Strictly speaking, mechanical life is a vague concept. Mechanical life should be a certain relationship with the time, 10 years spent 500 times and 1 year spent 500 times, obviously the situation is not the same. But there is not a more economical, more scientific way to measure.

The above is a brief introduction to the important indicators of electrical connector, learn more about the contents of the electrical connector, please pay attention to kingsignal official website.
