Many things in our daily life use connectors, such as LCD screens, computer wiring, battery wiring, and most household appliances. In addition, connectors are widely used in aviation, national defense and military systems.
The role of the connector is very single, but it is very important. It builds a bridge between the power supply and the electronic device, so that the current can flow normally and smoothly. The most indispensable part of an electronic device is the connector. Usually, multiple connectors are installed in an electronic device. The basic performance of the connector can be roughly divided into three types, namely mechanical performance, electrical performance and environmental performance.
As long as the mechanical performance of the connector is expressed in the insertion and extraction force, it can be subdivided into the insertion force and the extraction force. The insertion force should be as light as possible to facilitate the user's use, and the extraction force should be designed to be larger because of the separation force. If it is too small, it will easily affect the actual function of the connector.
Electrical properties include insulation resistance, dielectric strength and contact resistance.
Environmental performance is reflected in the heat resistance, humidity resistance, vibration resistance and impact resistance of the connector while it is working.
Now when people look back on the days when there was no connector, they can hardly imagine how they were working hard in a troublesome environment. If the electronic device is to be connected to the battery, the wire must be fixed between the two by electric welding, and the welding must be removed frequently, the battery is replaced, and then the welding is performed, which will increase both the cost and the labor. Additional expenses.
After having the connector, if you want to replace the battery, you only need to disconnect the connector, and then reconnect it after the replacement, which is convenient and cost-free.
