In the magnetic connector, the first contact assembly 100 and the second contact assembly 200 can maintain physical contact between the first contact assembly 100 and the second contact assembly 200 through magnetic attraction matching, i.e., magnetic attraction between the two contact assemblies, so as to maintain an electrical connection state between the two contact assemblies.

When the distance between the first contact assembly 100 and the second contact assembly 200 is sufficiently close, the magnetic attraction between the first contact assembly 100 and the second contact assembly accelerates the first contact assembly 100 and the second contact assembly 200 toward each other. Therefore, the first contact assembly 100 and the second contact assembly 200 collide each time they are magnetically engaged, and the collision force may damage the first contact assembly 100 and the second contact assembly 200.
