It should be understood that the arrangement form of the contact portion 52 is not limited thereto, as long as it is possible to achieve electrical connection with the contact end of the second conductive portion 4 when the cover 7 is rotated to a specific position.

Further, a through hole 117 is formed at a communication position between the transition structure 115 and the limit structure 112, and a damping structure 116 is provided at the through hole 117, where the damping structure 116 is used for providing resistance to the stop portion 731 when the stop portion 731 moves from the limit structure 112 to the transition structure 115. In the process of opening the cover body 7, the clamping part 731 is required to be adjusted from the limiting structure 112 to the transitional structure 115, and the damping structure 116 arranged at the passing opening 117 provides resistance to the clamping part 731, so that the clamping part 731 is more difficult to pass through the passing opening 117, and the clamping part 731 can be moved to the transitional structure 115 only when the resistance of the damping structure 116 is overcome, so that the cover body 7 is opened, and if misoperation is performed, a user can obviously feel, and the prevention effect of the misoperation of the user is further improved. Further, the damping structure 116 may also be used to prevent the movement of the detent 731 from the transition structure 115 to the stop structure 112, i.e., the damping structure 116 is a unidirectional damping structure disposed at the through opening 117, so as to achieve unidirectional movement of the detent 731 from the stop structure 112 to the transition structure 115 only.

It should be appreciated that the damping structure 116 is not limited to a structure of an elastic flap, as long as a resistance that blocks the click portion 731 from entering the limiting structure 112 from the transition structure 115 can be provided, for example, the damping structure 116 may be disposed on soft adhesive layers on two sides of the through opening 117, so that the width of the through opening 117 is smaller than the click portion 731, and when the click portion 731 enters the through opening 117 and has a sufficient pressing force, the soft adhesive layers may be pressed and deformed to two sides, and then enter into the limiting structure 112.
