1. Signal transmission
The basic function of the contact body is to transmit electrical signals and electricity. The material and design of the contact body determine the integrity and transmission efficiency of the signal. Highly conductive materials, such as metals, ensure that signals can pass through without hindrance.
2. Current bearing
The contact body needs to be able to carry a certain amount of current to meet the power demand of the device. Different contacts can be designed to adapt to different current levels of the application, ensuring that the equipment does not overload or overheat during normal operation.
3. Contact reliability
The better the contact design, the higher the reliability of the connection. Good contact design ensures that the contact body can maintain a stable contact pressure during insertion and removal, thereby reducing contact resistance and reducing the possibility of signal distortion.
4. Mechanical stability
The contact body will usually have appropriate mechanical strength and elasticity to ensure that it will not be deformed or broken during insertion and removal. This mechanical stability helps to meet the needs of different plug and plug times.
5. Corrosion resistance
The contact body is often surface treated with corrosion resistant materials (such as gold plating, silver plating, etc.) to improve its durability and reliability in wet or harsh environments. This treatment prevents oxidation and maintains good electrical conductivity.
6. Resist vibration and shock
In some applications, such as power tools or automobiles, the contact body must have a certain degree of vibration and shock resistance to ensure that it can still work stably in a vibration or shock environment.
7. Temperature rise management
Heat is generated during the contact process, and the design of the contact body needs to consider heat dissipation to avoid overheating affecting the contact performance. Reasonable contact design can effectively manage these heat and improve the safety of long-term use.
8. Electromagnetic interference (EMI) suppression
The design of the contact body should also consider electromagnetic compatibility (EMC), and reduce electromagnetic interference through reasonable contact methods and material selection to ensure that the signal is clear and accurate.
9. Connection reliability
Some high-end contact designs use special geometries and materials to improve the firmness of the connection and prevent poor contact caused by various external factors.

Sum up
The contact body of the communication contact plays a crucial role in the transmission of power and signals. By optimizing the design, materials and manufacturing process of the contact body, the performance and reliability of the electrical connector can be significantly improved, ensuring the stable operation of a variety of equipment in a variety of working environments. Choosing the right contact is critical to the overall function and long-term stability of the system.
