[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides Figure 1-4 The illustrated device for preventing accidental contact of a relay comprises a relay body 1, and a protective mechanism is provided on the outside of the relay body 1. The protective mechanism comprises a protective cover 2, a line clamping assembly 3 and an installation assembly 4. The protective cover 2 is sleeved on the outside of the relay body 1, and the outer wall of the protective cover 2 is symmetrically provided with grooves for inserting lines. The line clamping assembly 3 is arranged inside the protective cover 2 for fixing the lines, and the installation assembly 4 is arranged inside the protective cover 2 for connecting the relay body 1. By providing the protective cover 2, the interfaces of the relay body 1 can be covered together, leaving only the groove, which can solve the problem of dust and oil accumulation on the surface of the AC relay during use. The groove is filled with two clamping plates 33 according to the diameter and size of the line. The line can be fixed so that the position between the interface and the clamping block remains unchanged after the line is clamped. In this way, the problem of loosening of the interface connection due to external air flow or accidental contact after the connection is solved, thereby causing the wire to fall off, is solved, and the problem is easy to use.

[0029] Specifically, the line clamping assembly 3 includes a bidirectional screw 31, a slider 32, a clamping plate 33, and a knob 34. A rotation groove is defined within the protective cover 2. The end of the bidirectional screw 31 is rotatably interlocked with the inner wall of the rotation groove. The slider 32 is symmetrically disposed within the rotation groove, forming a screw drive with the bidirectional screw 31. The outer wall of the rotation groove defines a clamping groove that communicates with the groove. The clamping plate 33 is located within the clamping groove and is fixedly connected to the slider 32. The knob 34 is fixedly connected to one end of the bidirectional screw 31. The knob 34 has a T-shaped cross-section. Rotating the knob 34 drives the bidirectional screw 31 to rotate, thereby causing the slider 32 to move the multiple clamping plates 33 toward or away from each other, thereby clamping and securing lines of different specifications. After the lines are clamped, the position between the interface and the clamping block remains fixed. This prevents the interface connection from loosening due to external air flow or accidental contact, which can cause the wire to fall off, and facilitates use.

[0030] Furthermore, arc-shaped grooves are provided on opposite sides of the clamping plate 33, and rubber pads 35 are fixedly connected to the inner walls of the arc-shaped grooves. The outer walls of the rubber pads 35 are provided with anti-slip textures. The design of the arc-shaped grooves, the fixed connection of the rubber pads 35, and the setting of the anti-slip textures enable the clamping plate 33 to better fit the surface of the object when clamping the object, increase the friction, and prevent the object from sliding or falling during the clamping process. The rubber pads 35 have a certain elasticity and can adapt to objects of different shapes and sizes, providing a more stable clamping effect. The anti-slip texture further enhances the friction between the rubber pads 35 and the object, so that it can maintain good clamping performance under various working conditions.

[0031] Specifically, the mounting assembly 4 includes a clamping rod 41 and a tension spring 42. A rotation groove is provided on the inner wall of the clamping groove. The clamping rod 41 is arranged inside the rotation groove by rotating the rotating shaft. The outer wall of the relay body 1 is symmetrically provided with a clamping groove. The clamping rod 41 is slidably connected with the inner cavity of the clamping groove. The clamping rod 41 cooperates with the clamping plate 33. The tension spring 42 is arranged inside the rotation groove. One end of the tension spring 42 is fixedly connected to the inner wall of the rotation groove, and the other end of the tension spring 42 is fixedly connected to the clamping rod 41. Under the elastic action of the tension spring 42, the tension spring 42 is fixedly connected to the inner wall of the rotation groove. Under the force, one end of the clamping rod 41 can be closely attached to the inner wall of the rotating groove. After being inserted into the inside of the clamping groove, it can be tightly clamped with the clamping groove, so that the protective cover 2 can be clamped on the outside of the relay body 1. When disassembly is required, the two-way screw 31 can be rotated by the knob 34, so that the slider 32 drives the clamping plates 33 away from each other. At the same time, one of the clamping plates 33 can squeeze one end of the clamping rod 41, so that the clamping rod 41 rotates, thereby disengaging from the clamping groove and completing the disassembly of the protective cover 2.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
