[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4, A flexible printed circuit board with a protection structure, comprising a printed circuit board body 1, end heads 2, a support assembly and a protection assembly. End heads 2 are arranged on both sides of the printed circuit board body 1. The support assembly is arranged on both sides of the corresponding two groups of end heads 2. The support assembly includes a pin head 3, a pin rod 4, a stud 5 and a nut 6. A first through hole adapted to the pin rod 4 is arranged on one group of end heads 2, and a second through hole adapted to the stud 5 is arranged on the other group of end heads 2. The outer diameter of the stud 5 is smaller than the outer diameter of the pin rod 4, and the stud 5 and the pin rod 4 are arranged concentrically. One end of the pin rod 4 is connected to the pin head 3, the other end of the pin rod 4 is connected to one end of the stud 5, the other end of the stud 5 is connected to the nut 6, and a protection assembly for protecting the edge of the printed circuit board body 1 is further arranged on the pin rod 4.

[0021] During actual use, the two groups of pin rods 4 first pass through the first through holes of the corresponding end heads 2, and the stud 5 passes through the second through holes of the corresponding end heads 2. First through holes and second through holes are arranged on each group of end heads 2. The two groups of support assemblies are arranged oppositely. The gap between the two groups of end heads 2 is adapted to the pin rod 4. Then, the nut 6 is connected to the stud 5, and the two groups of end heads 2 are restricted between the two groups of opposite support assemblies. Then, in cooperation with the protection assembly, the edge of the printed circuit board body 1 is protected.

[0022] During actual use, friction lines 7 are arranged on the outer side of the nut 6 to facilitate driving the nut 6.

[0023] In this embodiment, the protection assembly includes a protection frame 8 in a U shape. Guide blocks 9 are arranged on both sides of the protection frame 8 close to one side of the printed circuit board body 1. Guide grooves adapted to the guide blocks 9 are arranged on the end heads 2. A protection groove adapted to the edge of the printed circuit board body 1 is arranged at the center of the protection frame 8 close to the printed circuit board body. The protection frame 8 has elasticity. The guide blocks 9 of the protection frame 8 are aligned with the guide grooves of the end heads 2 and slide in. If only the protection frame 8 is used to protect the printed circuit board body 1 with end heads 2, it is easy for the protection frame 8 to slip off, resulting in insufficient protection. If only the support assembly is used for rigid support, it is easy for the nut 6 to be accidentally unlocked, resulting in unstable support of the support assembly. Therefore, the protection frame 8 and the support assembly cooperate to support the printed circuit board body 1 with end heads 2, providing good protection for the printed circuit board body 1.
