What is the purpose of electrical copper rivets? Uncover the 'invisible guardian' of the electrical connection

Electrical Copper Rivetsnews-15-15​

In the microscopic world of electrical equipment and line connections, a small electrical copper rivet is playing an irreplaceable role. As an important component in the field of electrical connection, electrical copper rivets are widely used in many industries with their unique material advantages and scientific working principle, becoming the ' invisible guardian ensures the stable operation of the electrical system

Material Advantages: Lay the Foundation Stone

Copper Silver Contact for Switch
Superior Electrical Conductivity

Copper itself has extremely low electrical resistance, making it one of the most electrically conductive of all common metals. This characteristic enables copper rivets in the electrical connection can minimise power loss. The resistance of specialised copper rivets is reduced by approximately 40% compared to normal bolted connections. Effectively enhance the efficiency of power transmission, reduce operating costs, ensure that the weak current signal can be stable, ensure fast transmission, to ensure the high-speed operation of the equipment and accurate response.

Copper Silver Contact Rivet
Good thermal conductivity
 
In the operation of the electrical system, heat will inevitably be generated. Copper's excellent thermal conductivity can quickly conduct the heat out, preventing the local temperature from becoming too high for equipment damage. In some of the larger power appliances, copper rivets will heat parts and heat sinks are closely connected to the surrounding environment promptly, to maintain the equipment in the appropriate temperature range, greatly extending the service life of the equipment, and improving the stability of its operation.
Electrical Solid Copper ContactsStrong corrosion resistance
Opper is relatively stable in the natural environment, with a certain degree of oxidation and corrosion resistance. In some of the more severe electrical applications, electrical equipment is susceptible to water vapour, chemical erosion. Copper rivets to their corrosion resistance, can maintain good connection performance for a long time, to avoid poor contact due to corrosion, resistance increases, and other issues, to ensure the reliability of power transmission and equipment operation.
Red Copper Contacts
Excellent Mechanical Properties
Copper has good ductility and plasticity, easy to process into various shapes of rivets. At the same time, it also has a certain degree of strength and hardness, and can withstand certain mechanical stress. In the assembly process of electrical equipment, copper rivets can be firmly connected to different parts through the riveting process, to provide a reliable mechanical connection to ensure that the equipment in the vibration, impact, and other external forces, the components still maintain a stable connection state, do not loosen or fall off.
Principle of operation

The working principle of Copper Silver Contact Rivet is based on the ancient and effective method of joining, riveting, combined with the properties of the copper material. In the riveting process, usually use specialised riveting tools, such as rivet guns, hydraulic riveting machines, and so on. Take the commonly used semi-hollow copper rivets as an example. Firstly, the rivet will be inserted into the pre-punched connection holes, the size of the connection holes and rivets closely matched to ensure that the rivets can be firmly placed in them. Then, pressure is applied to one end of the rivet by a riveting tool, which deforms this end of the rivet to form a cap-like structure. The material properties of copper rivets play an important role in this process. As copper has good ductility, it can easily undergo plastic deformation under pressure to closely fit the surfaces of two or more parts being connected, thus achieving a mechanical connection. From the perspective of electrical connection, when copper rivets connect electrical components, their good electrical conductivity enables the smooth flow of electric current between the components. Because the copper rivets and the connected parts form a close physical contact, the contact resistance is extremely small, almost negligible, to ensure the stability and efficiency of current transmission. In some of the electrical connection requirements are extremely high occasions, such as aerospace electronic equipment, high-end medical equipment, etc., copper rivets of this principle of operation can ensure that the equipment in the complex electromagnetic environment and high reliability requirements, but still be able to operate stably and accurately.
