At the same time, the angle of the terminal 2 can be ensured to ensure reliable contact during matching. The sleeve 22 is in the shape of a round tube and is arranged in the accommodating space 121.

[0028] The contact spring 3 is made of a metal material with good conductivity, and is an annular spring. The contact spring 3 is disposed in the sleeve 22, and the contact spring 3 contacts the sleeve 22, so that the contact spring 3 and the terminal 2 are electrically connected. In this embodiment, one end (front end) of the sleeve 22 can be further stretched to form a boss 221, and one end of the contact spring 3 can contact the boss 221 to limit the contact spring 3 and prevent the contact spring 3 from falling off.

[0029] In addition, a rear cover 23 may also be disposed in the sleeve 22.
