[0030] The utility model will be further described in detail in conjunction with drawings and examples, these drawings are all simplified schematic diagram, just with schematic way to illustrate the basic structure of the utility model, thus it just shows the structure related to the utility model.

[0031] As Figure 1 Indicated, a kind of metal body insulation protective sleeve, including: corrugated insulation layer 4, protective top plate 2 and limiting bottom plate 1;

[0032] As Figures 2-3 Indicated, the inner wall of corrugated insulation layer 4 is equipped with inner contact surface 401, and the outer wall of corrugated insulation layer 4 is equipped with outer corrugated surface 402;

[0033] The circumferential outer wall of protective top plate 2 is fixedly connected with several first reinforcing ribs 3, and the one end of several first reinforcing ribs 3 is fixedly connected with the top of corrugated insulation layer 4;

[0034] The circumferential inner wall of limiting bottom plate 1 is fixedly connected with several second reinforcing ribs 5, and the one end of several second reinforcing ribs 5 away from limiting bottom plate 1 is fixedly connected with the bottom of corrugated insulation layer 4;

[0035] As Figures 1-4As shown, the corrugated insulation layer 4 is arranged in a corrugated conical shape, the corrugated conical shape of the corrugated insulation layer 4 is a gradually decreasing conical angle, which is gradually contracted from the bottom to the top of the corrugated insulation layer 4, the corrugated conical shape of the corrugated insulation layer 4 is a continuous and uniform wave shape, the first reinforcing rib 3 is arranged in an L-shaped structure, the second reinforcing rib 5 is arranged in an L-shaped structure, the bottom edge of the limiting bottom plate 1 extends outward to form a flange edge, the protective top plate 2 is made of polypropylene or polycarbonate plastic material, the material of the limiting bottom plate 1 is the same as that of the protective top plate 2, and the corrugated insulation layer 4 is made of elastic insulation material such as silicone rubber or fluororubber.

[0036] It should be noted that the corrugated insulation layer 4 is made of elastic insulation material, which can effectively isolate the metal body from the electrical connection with the outside. The setting of the inner contact surface 401 enables the corrugated insulation layer 4 to maintain good adhesion when contacting the metal body, and its elastic properties make the plugging process smoother, reducing friction and wear. The protective top plate 2 and the limiting bottom plate 1 form a stable structure with the corrugated insulation layer 4 through the first reinforcing rib 3 and the second reinforcing rib 5, thereby improving the structural strength of the corrugated insulation layer 4 and enabling it to withstand greater external force and impact.
