[0040] The terminal cable assembly 11 includes a terminal 12 and a clamping ring 13. The clamping ring 13 is sleeved on the terminal 12 and fixed in the axial direction of the terminal 12.

Optionally, the first side surface 122 and the second side surface 123 are chemically polished, and the specific process is to use an oxidant solution to oxidize the surface of the first side surface 122 and the second side surface 123 under certain conditions, and the oxide layer can gradually dissolve into the solution. The micro-protrusions of the first side surface 122 and the second side surface 123 are oxidized faster and more, while the micro-concave parts are oxidized slowly and less. Similarly, the oxide layer at the protrusions spreads more and faster than everywhere, and dissolves in the solution, so that the surface of the first side surface 122 and the second side surface 123 is gradually leveled to avoid scratching the snap ring 13. Chemical polishing is used to process the first side surface 122 and the second side surface 123, so as to protect the thin walls of the first side surface 122 and the second side surface 123 and avoid affecting the material stiffness, thereby making the first side surface 122 and the second side surface 123 smooth and glossy.
