　　Crown spring and claw spring are two common elastic elements widely used in electronic connectors to ensure reliable contact between pin and socket.

　　Crown spring, also known as coil spring, is shaped like a rolled spring and is usually used for axial compression. One of the main features of crown spring is that it can provide high elastic force in a small space, so it performs well in applications that require frequent plugging and unplugging. The design of crown spring enables it to expand or contract radially when subjected to axial pressure, thereby maintaining good contact between pin and socket. In addition, crown spring also has a long service life and stable contact resistance.

　　Claw spring is a spring structure with multiple elastic claws, which can be straight, curved or other shapes. The main advantage of claw spring is that it can provide multi-point contact, thereby increasing contact area and reliability. When the claw spring is under pressure, each claw will fit with the contact surface separately. Even if some claws are worn or fail, the other claws can still maintain good contact, so it has a high fault tolerance.

　　In general, crown springs are suitable for occasions where space is limited and frequent plugging and unplugging is required, while claw springs are more suitable in applications that require high reliability and fault tolerance.
