Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an environmentally friendly grounding cable. Background Art

[0002] Grounding cables generally refer to cables used for grounding in buildings or equipment. Their function is to discharge current through the ground to ensure safety and prevent damage to electrical equipment. Grounding cables are usually connected to the grounding system of a building or equipment to conduct current into the ground.

[0003] During the recycling process of discarded cables, the outer sheath of the cable needs to be cut open by a cutting device to recycle the wire core and steel belt armor inside the cable. The existing steel belt armor is connected to the inner side of the cable by winding. When recycling, after the outer sheath is cut open, the cable needs to be twisted to remove the steel belt outside the cable. Therefore, those skilled in the art provide an environmentally friendly grounding cable to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an environmentally friendly grounding cable, comprising a wire core, an insulating layer is arranged on the outside of the wire core, a filling layer is arranged on the outside of the insulating layer, a protective layer is coated on the outside of the filling layer, an outer sheath is arranged on the outside of the protective layer, and a plurality of wear-resistant strips are arranged on the outside of the outer sheath;

[0005] The protective layer comprises a connection shell, a filling steel belt is connected to the inner side of the connection shell, a connection groove is arranged on the outer side of the connection shell, a connection steel belt is inserted into the connection groove, and inward protrusions are arranged at both ends of the connection steel belt.

[0006] Preferably, the wire core is made of tinned copper.

[0007] Preferably, the insulating layer is a mica tape.

[0008] Preferably, the outer sheath and the wear-resistant strip are made of halogen-free flame-retardant thermoplastic polyurethane.

[0009] Preferably, a groove is provided inside the outer sheath, and the groove is located between adjacent wear-resistant strips.

[0010] Preferably, a plurality of through holes are provided inside the wear-resistant strip.

[0011] Preferably, the wear-resistant strip is provided with a plurality of grooves.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model is designed with a protective layer, which protects the internal wire core by splicing. When recycling, after the outer sheath is cut open, the protective layer is separated from the connecting shell by the connecting steel belt, so that it is easy to recycle.

[0014] 2. The utility model is designed with an outer sheath, and a groove is provided on the outer sheath. The groove is spaced apart from the wear-resistant strips so that the groove is located between the wear-resistant strips. Therefore, when cutting the outer sheath, the groove can reduce the depth of the cutting device cutting into the inner part of the outer sheath, thereby reducing the difficulty of cutting.

[0021] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 In this embodiment, an environmentally friendly grounding cable is provided, including a core 1, an insulating layer 2 is provided on the outside of the core 1, a filling layer 3 is provided on the outside of the insulating layer 2, a protective layer 4 is coated on the outside of the filling layer 3, an outer sheath 5 is provided on the outside of the protective layer 4, and a plurality of wear-resistant strips 6 are provided on the outer side of the outer sheath 5;

[0023] The protective layer 4 includes a connecting shell 41, a filling steel belt 43 is connected to the inner side of the connecting shell 41, a connecting groove is provided on the outer side of the connecting shell 41, a connecting steel belt 42 is inserted into the connecting groove, and inward protrusions are provided at both ends of the connecting steel belt 42. The protrusions are recessed toward the center, so that multiple shells 41 are connected into a ring shape, thereby covering the filling layer 3 therein.

[0024] When in use, the protective layer 4 protects the internal wire core 1 by splicing. When recycling, after cutting the outer sheath 5, the protective layer 4 is separated from the connecting shell 41 by the connecting steel belt 42, thereby detaching the protective layer 4 from the outside of the filling layer 3, so as to facilitate recycling.

[0025] A groove 51 is provided on the outer sheath 5, and the groove 51 is spaced apart from the wear-resistant strips 6 so that the groove 51 is located between the wear-resistant strips 6. Therefore, when cutting the outer sheath 5, the groove 51 can reduce the depth of the cutting device cutting into the outer sheath 5, thereby reducing the difficulty of cutting.

[0026] In further embodiments, see Figure 1 The wire core 1 is made of tinned copper.

[0027] In further embodiments, see Figure 1 The insulating layer 2 is a mica tape, and the mica tape is used to increase the fire resistance of the cable.

[0028] In further embodiments, see Figure 1 The outer sheath 5 and the wear-resistant strip 6 are made of halogen-free flame-retardant thermoplastic polyurethane material.

[0029] In further embodiments, see Figure 1 The outer sheath 5 is provided with a groove 51 inside, and the groove 51 is located between the adjacent wear-resistant strips 6. When recycling, the recycling personnel cut the outer sheath 5 between the wear-resistant strips 6, and reduce the thickness of part of the outer sheath 5 through the groove 51, so that the cutting device can be ensured during cutting, and a thinner thickness can be cut.

[0030] In further embodiments, see Figure 3 The wear-resistant strip 6 is provided with a plurality of through holes 61. The through holes 61 reduce the material usage of the wear-resistant strip, save costs, and also reduce the weight of the cable. When the cable is supported by the support member, the support pressure of the support member is reduced.

[0031] In further embodiments, see Figure 4 The wear-resistant strip 6 is provided with a plurality of slots 62. The slots 62 reduce the radial strength of the cable, thereby making the cable easy to bend.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
