1. Prevent short circuits
The insulator effectively prevents the leakage of current between adjacent conductive components and prevents the occurrence of short circuits. This is essential to ensure the safe and proper operation of the equipment, especially in high current and high voltage applications.
2. Provide electrical isolation
Insulators provide electrical isolation for different parts of the circuit, preventing electrical interference and series effects, thereby protecting equipment and users. It ensures consistency and signal integrity, reducing unnecessary interaction between different circuits.
3. Improve your pressure tolerance
The thickness and material selection of the insulator can improve the voltage resistance of the communication contact, ensuring that it will function properly in high voltage applications without breakdown. This is especially important for high-frequency, high-voltage communication systems.
4. Environmental protection
Insulators protect internal electrical components from moisture, dust, chemicals, and physical damage. Many insulation materials are waterproof and dust-proof, helping to extend the service life of equipment.
5. Signal integrity
In some high-frequency applications, the material and thickness of the insulator has an important impact on the integrity of the signal transmission. Proper insulators can reduce signal interference and attenuation, thus ensuring high-quality data transmission.
6. Mechanical strength and stability
Insulators provide mechanical support to maintain the correct position of contacts and other components, thereby increasing the mechanical strength and stability of the entire connector and preventing poor contact during insertion and removal.
7. Thermal insulation
When an electric current passes through, heat is generated, and insulators usually have good thermal insulation characteristics to prevent heat from damaging other components or causing equipment to overheat.
8. Electromagnetic interference shielding
Certain insulation materials can help shield electromagnetic interference (EMI) and improve the electromagnetic compatibility (EMC) of equipment. This is very important to ensure that the communication signal is not affected by external electromagnetic interference.
9. Processing and forming
Insulation materials can be formed by different processing processes (such as injection molding, extrusion, etc.) in various shapes, which is easy to design complex connector structures and flexibly adapt to the needs of various equipment.
10. Security
The choice and design of insulator materials are also closely related to the safety of the equipment. The use of suitable insulation materials can protect users from potential hazards such as electric shocks.

Sum up
The insulators in the communication contacts play a crucial role in the overall connector function. It not only ensures the safety and stability of the circuit, but also improves the durability and reliability of the equipment. Choosing the right insulation material and design scheme is the key to ensure the efficient and safe operation of the communication system.
