What is the function of a pressure connector?

The function of a pressure connector is to form a cold weld between the conductor and the connector. This is achieved through a mechanical process where pressure is applied to bring the surfaces of the conductor and connector into close contact, leading to the microscopic protrusions of the metal surfaces deforming and merging at a molecular level. This creates a strong and reliable electrical connection without the need for heat, which is beneficial in preventing damage to the conductor due to excessive heat that can occur with traditional soldering methods.

Additionally, cold welding helps to ensure that the connection has low resistance, which is crucial for efficient electrical performance. This method enhances the conductivity and longevity of the connection, making it suitable for applications where maintaining electrical integrity is essential. Overall, forming a cold weld provides a robust and efficient means of connecting conductors in an electrical system.
