DETAILED DESCRIPTION

[0023] 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.

[0024] When implementing: Figure 1-4 As shown, a flexible printed circuit board connection device that is easy to fix includes: a mounting plate 1, a flexible printed circuit board body 2 is arranged on the top of the mounting plate 1; a fixing mechanism 3, the fixing mechanism 3 for quickly fixing the flexible printed circuit board body 2 is arranged on the inner wall of the mounting plate 1; wherein the fixing mechanism 3 includes a mounting rod 31 fixedly connected to the inner wall of the flexible printed circuit board body 2, mounting grooves 32 are opened on the top of the mounting plate 1, the surface of the mounting rod 31 is clamped on the inner wall of the mounting groove 32, the inner wall of the mounting plate 1 is slidably connected with a fixing frame 33, the rear end of the fixing frame 33 is clamped on the inner wall of the mounting rod 31, the inner wall of the mounting plate 1 is rotatably connected with a rotating rod 34, the surface of the rotating rod 34 is fixedly connected with a cam 35, and the inner wall of the mounting plate 1 is provided with a fixing component 36.

[0025] When the flexible printed circuit board needs to be fixed, the flexible printed circuit board is aligned and placed on the mounting plate 1, so that the mounting rod 31 is clamped in the mounting groove 32, and the rotating rod 34 is rotated. The rotation of the rotating rod 34 drives the cam 35 to rotate, and the rotation of the cam 35 pushes the fixing frame 33 to be clamped in the mounting rod 31, so that the flexible printed circuit board body 2 is quickly fixed on the mounting plate 1. At this time, the flexible printed circuit board body 2 is assembled.

[0026] like Figure 3As shown, the fixing assembly 36 includes a magnetic rod 361 slidably connected to the inner wall of the rotating rod 34, and a magnetic groove 362 is opened on the top of the mounting plate 1. The surface of the magnetic rod 361 is clamped on the inner wall of the magnetic groove 362 and the opposite poles attract each other. The lower end of the surface of the magnetic rod 361 and the shape of the magnetic groove 362 are both truncated cones.

[0027] The attraction between the magnetic rod 361 and the magnetic slot 362 is due to the interaction of the magnetic fields generated therebetween. The magnetic field generated by the magnetic rod 361 is in one direction, while the magnetic field generated by the magnetic slot 362 is in another direction. According to the law of magnetic field interaction, two objects with different magnetic field directions will attract each other.

[0028] The magnetic rod 361 is pushed, and the magnetic rod 361 moves in the rotating rod 34 and is engaged and adsorbed in the magnetic groove 362, thereby locking the rotating rod 34, so that the fixing frame 33 is stably engaged in the installation rod 31.

[0029] like Figure 3-4 As shown, the inner wall of the mounting plate 1 is slidably connected to a limiting rod 363, the surface of the limiting rod 363 is clamped on the inner wall of the magnetic rod 361, one end of the limiting rod 363 is fixedly connected to a spring 364, the other end of the spring 364 is fixedly connected to the inner wall of the mounting plate 1, and an anti-slip hole 367 is opened on the surface of the limiting rod 363, and the surface of the anti-slip hole 367 is clamped on the inner wall of the magnetic rod 361.

[0030] It should be noted that the flexible printed circuit board body 2, the cam 35 and the spring 364 in the above description are all relatively mature devices in the prior art, and the specific models can be selected according to actual needs.

[0031] The elastic force of the spring 364 pushes the limiting rod 363 to be clamped in the magnetic rod 361 , so that the magnetic rod 361 is firmly locked in the magnetic groove 362 .

[0032] like Figure 3 As shown, the surface of the rotating rod 34 is fixedly connected to the connecting rod 365, the surface of the magnetic rod 361 is slidably connected to the inner wall of the connecting rod 365, the top of the mounting plate 1 is fixedly connected to the stopper 366, and the surface of the connecting rod 365 contacts one side of the stopper 366.

[0033] The rotating rod 34 rotates to drive the connecting rod 365 to rotate and abut against the stopper 366, so that the rotating rod 34 stops rotating, so that the fixing frame 33 can be accurately engaged with the installation rod 31.

[0034] When the utility model is in use, the flexible printed circuit board is aligned and placed on the mounting plate 1, so that the mounting rod 31 is clamped in the mounting groove 32, and the rotating rod 34 is rotated. The rotating rod 34 rotates to drive the connecting rod 365 and the cam 35 to rotate, and the cam 35 rotates to push the fixing frame 33 to be clamped in the mounting rod 31. The connecting rod 365 rotates and abuts against the stopper 366, and the rotation of the rotating rod 34 can be stopped, and the magnetic rod 361 is pushed. The magnetic rod 361 moves in the rotating rod 34 and is clamped and adsorbed in the magnetic groove 362. The elastic force of the spring 364 pushes the limiting rod 363 to be clamped in the magnetic rod 361, so that the magnetic rod 361 is firmly locked in the magnetic groove 362, so that the flexible printed circuit board body 2 is quickly fixed on the mounting plate 1, and the flexible printed circuit board body 2 is assembled at this time.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
