[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] The following will be combined with the drawings in the embodiments of the utility model, Figures 2-4 The application will be further described in detail,

[0028] The embodiments of the application disclose an insulating protective sleeve, which comprises an upper sheath 1 and a lower sheath 2, the upper sheath 1 and the lower sheath 2 are both semicircular structures, and the upper sheath 1 and the lower sheath 2 are buckled to form a circular sheath 3 wrapped outside the insulating wire.

[0029] The upper sheath 1 and the lower sheath 2 are both three-layer sheath structures, the middle layer is a hard sheath, and the inner and outer layers are soft sheaths, and the bottom sides of the upper sheath 1 are matched with the top sides of the lower sheath 2 to be buckled and sealed.

[0030] The three-layer sheath structure on the upper sheath 1 includes an upper semi-circular hard sleeve 11 located at the center, an inner layer of upper semi-circular silica gel soft sleeve 12 and an outer layer of upper semi-circular silica gel soft sleeve 13 which are heat-bonded on both sides of the upper semi-circular hard sleeve 11. The upper sheath 1 also includes a left upper silica gel buckle 14 and a right upper silica gel buckle 15 which are heat-bonded on both ends of the upper semi-circular hard sleeve 11 and located between the inner layer of upper semi-circular silica gel soft sleeve 12 and the outer layer of upper semi-circular silica gel soft sleeve 13.

[0031] The three-layer sheath structure on the lower sheath 2 includes a lower semi-circular hard sleeve 21 located at the center, an inner layer of lower semi-circular silica gel soft sleeve 22 and an outer layer of lower semi-circular silica gel soft sleeve 23 which are heat-bonded on both sides of the lower semi-circular hard sleeve 21. The lower sheath 2 also includes a left lower silica gel buckle 24 and a right lower silica gel buckle 25 which are heat-bonded on both ends of the lower semi-circular hard sleeve 21 and located between the inner layer of lower semi-circular silica gel soft sleeve 22 and the outer layer of lower semi-circular silica gel soft sleeve 23.

[0032] The upper semi-circular hard sleeve 11 located at the center provides structural strength and protects the insulated wire from external impact and pressure. The inner layer of upper semi-circular silica gel soft sleeve 12 and the outer layer of upper semi-circular silica gel soft sleeve 13 on both sides provide flexibility so that the sheath will not be damaged, and the heat-bonding of the inner layer of upper semi-circular silica gel soft sleeve 12 and the outer layer of upper semi-circular silica gel soft sleeve 13 with the upper semi-circular hard sleeve 11 can provide better sealing effect to prevent the intrusion of moisture and other harmful substances.

[0033] Similar to the upper sheath 1, the lower semi-circular hard sleeve 21 is the central layer, providing strength and support, and the inner layer of lower semi-circular silica gel soft sleeve 22 and the outer layer of lower semi-circular silica gel soft sleeve 23 ensure a tight fit between the sheath and the insulated wire without losing the sealing effect.

[0034] The left upper silica gel buckle 14 is buckled with the left lower silica gel buckle 24, and the right upper silica gel buckle 15 is buckled with the right lower silica gel buckle 25. The buckling of the left upper silica gel buckle 14 with the left lower silica gel buckle 24 and the right upper silica gel buckle 15 with the right lower silica gel buckle 25 allows the sheath to be quickly installed in place. The buckling structure ensures the stability of the connection between the two parts of the sheath, preventing the sheath from separating due to vibration or external force during use. The buckling design allows the sheath to be quickly separated when maintenance or replacement is needed, reducing the time and cost of maintenance work.

[0035] The left upper silica gel buckle 14 is provided with an inverted convex buckle groove A16, and the inverted convex buckle block A17 on the left lower silica gel buckle 24 is buckled with the inverted convex buckle groove A16. The right upper silica gel buckle 15 is provided with a convex buckle block A26, and the convex buckle groove A27 on the right lower silica gel buckle 25 is buckled with the convex buckle block A26.

[0036] The design of the inverted convex buckle slot A16 and the inverted convex buckle A17, and the convex buckle A26 and the convex buckle slot A27, provides an accurate buckling interface, ensuring the sealing and durability of the sheath. This design reduces the possibility of misoperation during installation, because only the corresponding buckle slot and buckle can be buckled correctly. The fastening effect of the buckling structure ensures that the sheath can still maintain its function under extreme conditions (such as high temperature, low temperature, humidity change, etc.), increasing the safety performance of the insulated conductor.

[0037] The insulation protective sheath, in terms of structural design, is composed of an upper sheath 1 and a lower sheath 2, both of which are semi-circular structures, and form a complete circular sheath 3 after buckling, covering the outside of the insulated conductor. Both the upper and lower sheaths 2 adopt a three-layer structure design, with the middle layer being a hard sheath and the inner and outer layers being soft sheaths. This design aims to provide good mechanical strength and impact resistance, while maintaining the flexibility and sealing of the outer surface.

[0038] In terms of aesthetics, the design of the outward convex buckle is avoided, making the overall appearance more smooth and beautiful; in terms of strength and impact resistance, the use of a middle hard sheath layer improves the mechanical strength and impact resistance of the overall sheath. In terms of sealing, the buckle type butt joint sealing is adopted, ensuring the sealing performance of the sheath in harsh environments.

[0039] The buckle type design is adopted, with silicone buckling strips provided on the left and right ends of the upper sheath 1 and the lower sheath 2, namely the left upper silicone buckling strip 14, the right upper silicone buckling strip 15, the left lower silicone buckling strip 24 and the right lower silicone buckling strip 25. The buckling mode is as follows: the left upper silicone buckling strip 14 and the left lower silicone buckling strip 24 are buckled through the inverted convex buckle slot A16 and the inverted convex buckle A17; the right upper silicone buckling strip 15 and the right lower silicone buckling strip 25 are buckled through the convex buckle A26 and the convex buckle slot A27. These buckling strips cooperate with each other to achieve buckling through the design of the buckle slot and the buckle, ensuring the sealing and stability of the sheath.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent substitution, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
