[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] This specific embodiment provides a grounding wire anti-breakage sheath, which solves the technical problem in the prior art where the bushing is blurry due to the large gap between the bushing and the grounding wire.
[0025] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.
[0026] Reference Figures 1-4This utility model provides a grounding wire anti-breakage sheath, including a sleeve 1 and a fixing component 2. The sleeve 1 is fitted onto the grounding wire, and the fixing component 2 is installed at one end of the sleeve 1 to fix the sleeve 1 to the grounding wire. The sleeve 1 includes a spring 11 and a transparent soft shell 12. The soft shell 12 wraps around the outside of the spring 11, and both ends of the soft shell 12 are turned inward toward the inner ring of the spring 11 to form a protective layer 13, so that the protective layer 13 is in close contact with the end of the grounding wire. The soft shell 12 is made transparent to facilitate people to see the copper wire and the connector inside the grounding wire. Whether there is any wire breakage; In order to minimize the gap between the circumference of the sleeve 1 and the circumference of the ground wire, the spring 11 includes a first connecting section 111 and a second connecting section 112, wherein the diameter of the first connecting section 111 is smaller than the diameter of the second connecting section 112, and the first connecting section 111 is connected to the end of the ground wire. This can reduce the diameter of the sleeve 1 so that the sleeve 1 is in close contact with the circumference of the ground wire. The fixing component 2 is located at the end of the second connecting section 112 away from the first connecting section 111 to facilitate fixing the sleeve 1.
[0027] The solution is further optimized. The fixing component 2 includes a sleeve 1 fixing part 21 for locking, a first threaded part 22, and a first nut 24. The fixing part 21 of the first threaded part 22 is away from the spring 11, and the first threaded part 22 is provided with a first opening. The first nut 24 is installed on the first threaded part 22 so that the first threaded part 22 locks the ground wire. Since the first threaded part is provided with a first opening, it is convenient to be sleeved on the ground wire. At the same time, when people tighten the first nut, the first threaded part 22 can be in close contact with the ground wire, increasing the friction between the two and preventing it from falling off.
[0028] To further optimize the design, in order to facilitate the locking of the sleeve 1 by the fixing component 2, the fixing component 2 also includes a second threaded part 23 and a second nut 25. The second threaded part 23 is installed at the end of the fixing part 21 near the spring 11, and a second opening is provided on the second threaded part 23. The second nut 25 is installed on the second threaded part 23 to fix the second threaded part 23 to lock the sleeve 1. Since the second threaded part is provided with a second opening, it is convenient to put it on the sleeve 1. At the same time, when people tighten the second nut, the second threaded part 23 can be in close contact with the sleeve, increasing the friction between the two and preventing it from falling off.
[0029] Further optimization of the design involves spraying an insulating layer onto spring 11, giving the spring itself insulating properties and preventing sparking.
[0030] To further optimize the design, in order to prevent dust from entering from the connection between the fixing part 21 and the sleeve 1, the fixing part 21 is provided with a groove 211 for the sleeve 1 to be inserted. The bottom of the groove 211 is provided with a through hole for the ground wire to pass through, so that the sleeve 1 is installed in the groove. At the same time, the top surface of the groove 211 is provided with a second threaded part, which facilitates the formation of a seal.
[0031] To further optimize the design, in order to ensure the sealing between the groove 211 and the sleeve 1, an annular anti-slip protrusion 212 is provided on the side of the groove 211.
[0032] Further optimization of the scheme: if the length of the first connecting segment 111 is relatively long and the diameter of the first connecting segment 111 is relatively small, it will be inconvenient to insert the ground wire. Therefore, the diameter of the first connecting segment 111 is 18-19 mm and the length is 25-35 mm, so that the ground wire can be smoothly inserted into the sleeve 1.
[0033] Further optimization of the design: the diameter of the second connecting section 112 is 19.5-20 mm and the length is 100-120 mm. If the length of the second connecting section 112 is too short, it will be inconvenient for the ground wire to bend. Therefore, the length of the second connecting section 112 is 100-120 mm. In order to reduce the chance of dust entering the sleeve, the diameter of the second connecting section 112 is 19.5-20 mm.
[0034] Further optimization of the design: the length of the protective layer 13 is 10-12 mm. Since the longer the protective layer 13 is, the more inconvenient it is to bend and form. Therefore, the length of the protective layer 13 is 10-12 mm while ensuring the sealing effect.
