[0018] The embodiment of the present application discloses a protective limiter, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a limiter body 1 and input and output connectors provided at both ends of the limiter body 1, and a mounting base 2. The top of the mounting base 2 is provided with a mounting cavity for accommodating the limiter body 1, and the two side walls of the mounting cavity are provided with avoidance openings 21 for the input and output connectors to pass through. The ends of the input and output connectors are both sleeved with flexible rings 11, and the inner side walls of the mounting cavity are adhered with flexible pads 3 for contacting the side walls of the limiter body 1. A sealing cover 4 for closing the mounting cavity is provided on the top of the mounting base 2, and vibration damping members 5 for contacting the top and bottom of the limiter body 1 are respectively provided on the sealing cover 4 and the bottom wall of the mounting cavity.

[0019] In an embodiment of the present application, the flexible ring 11 and the flexible pad 3 can be made of flexible materials such as rubber. The flexible ring 11 can protect the input connector and the output connector. The limiter body 1 is installed in the mounting cavity of the mounting seat 2, and the flexible pad 3 is adhered to the inner side wall of the mounting cavity, which can protect the limiter body 1. The sealing cover 4 and the shock-absorbing member 5 on the bottom wall of the mounting cavity can play a vibration-absorbing role when the limiter falls to the ground, further improving the protection of the limiter body 1. Through this design, a protective limiter of the present application has the effect of improving the protection of the limiter body 1.

[0020] Specifically, the vibration-absorbing member 5 is a damping spring shock absorber.

The protective frame 6 is provided with a through hole 61 at one end away from the mounting base 2 for the external wiring harness to pass through.

[0022] In the embodiment of the present application, the protective frame 6 can further improve the protection of the input connector and the output connector.

[0023] Furthermore, the protection frame 6 is provided on the mounting seat 2 for damping rotation, and the rotation axis of the protection frame 6 is perpendicular to the axis of the input connector / output connector.

[0024] In this embodiment, the protective frame 6 is rotatably mounted on the mounting base 2 via a damping shaft. During teaching experiments and training sessions, some electronic components need to be hung on the wall for easy viewing by trainees. Hooks are provided on the walls, and the instructor simply rotates the protective frame 6 to attach the limiter.
