I. What are the main factors that make a difference in the use of pin connectors? There are many connectors on the motherboard of a computer, simply from the outside to the inside, for example, the USB port on the chassis and the power connector are connectors, but they are not the same in detail, and then on the inside, the connection between the circuit board and the circuit board, such as the slot for the graphic card, is also a connector, and this form of it should be called a gold finger, connector pins are widely used in automotive, computers, communications, military and many other fields . The main factors affecting the differences in the use of pin connectors: 1, temperature: pin connector accelerated corrosion, the formation of surface oxidation, contact pressure loss. 2, humidity: accelerate the pin connector corrosion, the formation of surface oxidation, degradation of plastic molds. 3, transportation and storage: in the process of transportation, if the collision, it will directly damage the pin connector. 4, wear and tear: with the pin connector to find the time when the connector will be worn out.
