They are suitable for the development of electronic products towards high density, miniaturization, and high reliability. Flexible circuit boards can be divided into one-time folding, static flexible circuit boards, and dynamic flexible circuit boards according to installation and application.

[0003] A Chinese patent with publication number: CN213028671U discloses "a splicable flexible circuit board, comprising a first circuit board and a second circuit board, a first connecting plate is provided on one side of the first circuit board, a first sliding groove is provided on one side of the first connecting plate, a first sliding block is provided on the other side of the first connecting plate, the other end of the first circuit board is fixedly connected to the second connecting plate, and a second sliding groove is provided on one side of the second connecting plate. In this splicable flexible circuit board, the first connecting plate and the second connecting plate can be slidably connected, so that the positions of the first connecting plate and the second connecting plate are fixed, and the matching connection of the bolt and the nut is further fixed, the depth of the regular hexagonal fixing groove is less than the height of the screwed part of the bolt, so that the exposed part of the bolt forms a support body, so that the circuit board does not contact the lower part, which is more conducive to ventilation, and the heat dissipation fan dissipates heat from the top of the circuit board to prevent the circuit board from being damaged due to excessive temperature";

[0027] Specifically, by fixing two sockets 132 on the outer wall of the connecting shell 2 13, the sockets 132 can be aligned with the docking groove 146 and quickly inserted, and the sockets 132 can be quickly limited by the limit block 185, so that the connecting shell 2 13 and the connecting shell 1 12 can be rotated for adjustment, and the insert block 16 can be inserted into the inside of the regulating ring 15 to limit the angle of the limit tube 14 and the connecting shell 2 13 as needed. The lifting rod 181 can quickly separate the connecting shell 2 13 and the connecting shell 1 12, and the docking is convenient, the limiting is stable, and it is easy to use.

[0028] Embodiment 1

[0029] like Figure 7 As shown, in this embodiment, two installation grooves 142 are provided inside the limit tube 14, and a limit seat 144 is fixedly connected between the inner walls of the two installation grooves 142. A docking groove 146 is provided on the outer wall of the limit seat 144, and the socket 132 is movably engaged with the adjacent docking groove 146.

[0030] In this embodiment, the installation groove 142 is used to install the limit seat 144. The two clamping seats 132 can be aligned with the rectangular hole 121 and inserted into the interior of the connecting shell 12, and the two clamping seats 132 are respectively inserted into the adjacent docking grooves 146 to achieve the preliminary docking of the connecting shell 12 and the connecting shell 2 13. When the connecting shell 2 13 rotates, the limit tube 14 is driven to rotate, thereby driving the regulating ring 15 to rotate through the limit sleeve 141. After the rotation is completed, the movable plug 16 is inserted into the adjacent slot 151, so as to quickly limit the angle of the regulating ring 15 and the limit tube 14.

[0031] like Figure 5 As shown, in this embodiment, the regulating module 17 includes a sliding block 172, and a screw rod 171 is rotatably connected to the inner rear side wall of the connecting shell 12.

The top of the connecting shell 12 is fixedly connected with a guide plate 188.

[0036] During specific implementation, when the holder 132 is inserted into the docking groove 146, the top of the holder 132 pushes the limit block 185 to move upward, and then, driven by the second spring 183, the two limit blocks 185 are inserted into the adjacent slots 133, thereby quickly limiting the connection between the holder 132 and the limit seat 144, and the card plate 184 is slidably limited by the slide groove 145, so that the pull rod 181 and the limit tube 14 are synchronized, and the limit tube 14 can be synchronously regulated when the pull rod 181 is rotated, and the pull rod 181 and the two limit blocks 185 can be lifted by lifting the pull block 186, thereby synchronously releasing the limit of the two holders 132, so that the connecting shell 2 13 and the connecting shell 1 12 can be quickly separated, and by penetrating the auxiliary groove 187 to compare the position of the guide plate 188, the angle of the limit tube 14 and the two limit seats 144 can be judged, so that the docking and calibration of the connecting shell 2 13 and the connecting shell 1 12 are convenient.
