To solve this problem, an arc notch 311 is concavely formed on one side of the upper terminal 31 close to the lower terminal 32, and the rotating shaft 42 is located at the arc notch 311. By providing the arc-shaped notch 311, the upper terminal 31 can be positioned closer to the lower terminal 32. This makes the distance between the upper terminal 31 and the lower terminal 32 smaller, and the upper and lower sides of the FPC board can be clamped by the smaller-sized contact portion 33, thereby ensuring the strength of the contact portion 33.

In order to facilitate the assembly of the cover plate 4 to the base 1, the two second side plates 13 are opened with guide grooves 134 on one side facing the connecting grooves 14, and the guide grooves 134 extend from the connecting holes 131 in a direction away from the first side plate 12 and penetrate through the second side plates 13. An operator can slide the cover plate 4 and the rotating shaft 42 into the guide grooves 134 with both ends of the rotating shaft 42 positioned at the connecting holes 131 of the two second side plates 13, and then install the reinforcing members 2 from the sides of the two second side plates 13 away from the connecting grooves 14, so that the reinforcing sleeves 21 of the reinforcing members 2 enter the connecting holes 131, and so that both ends of the rotating shaft 42 enter the reinforcing sleeves 21 at both ends, respectively. The installation can be accomplished with reinforcement 2 and base 1 fixed connection to operating personnel.
