AI Technical Summary
The contacts of a relay are subjected to high stress over a long period of time, resulting in poor structural and operational reliability. The connection between the contacts and conductive parts is also unreliable, affecting the reliability and service life of the relay and power distribution equipment.
By connecting and fixing the relay body to the base and electrically connecting the contacts to the first conductive element, the functions of mechanical fixing and electrical conduction are separated. The relay body mainly undertakes the mechanical fixing function, while the contacts mainly undertake the overcurrent conduction function. A structure combining rigid and flexible sections is adopted. The flexibility and deformation adaptability of the flexible section are utilized to absorb positional deviations under conditions such as assembly tolerances and thermal expansion and contraction, reducing the risk of assembly interference from rigid connections.
It significantly reduces the stress, such as vibration and impact loads, on the contacts, reduces the risk of stress concentration, contact fatigue and structural damage, improves the structural and operational reliability of the contacts, optimizes the connection reliability between the contacts and conductive parts, and extends the service life of relays and power distribution devices.
