[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a cable joint moisture-proof cover, including a first protective cover 1 and a second protective cover 2. The first protective cover 1 has an annular connecting plate 3 on one side, and the second protective cover 2 has an annular connecting groove 4 on one side. The first protective cover 1 and the second protective cover 2 are both provided with connecting flanges 5 on the side near the annular connecting plate 3 and the side near the annular connecting groove 4, respectively. The first protective cover 1 and the second protective cover 2 are both provided with annular mounting seats 6 on the side away from the annular connecting plate 3 and the side away from the annular connecting groove 4, respectively. A protective sleeve 7 is installed on one side of the annular mounting seat 6, and a clamp 8 is installed on one side of the protective sleeve 7. Several springs 9 are installed at the upper and lower ends of the inner side of the first protective cover 1 and the upper and lower ends of the inner side of the second protective cover 2. A pair of protective plates 10 are installed on the inner side of the first protective cover 1 and the second protective cover 2 through the springs 9.

[0028] The size of the annular connecting groove 4 matches the size of the annular connecting plate 3, so that the annular connecting groove 4 can be inserted into the annular connecting groove 4, thereby enabling the first protective cover 1 and the second protective cover 2 to be connected together.

[0029] Among them, the inner side of each pair of protective plates 10 is provided with anti-slip pads 11, which increases the adhesion between the pair of protective plates 10 and the cable, thereby improving the stability of the first protective cover 1 and the second protective cover 2 during use.

[0030] The protective cover 7 is made of rubber, which has good elasticity and plasticity, and can form a tight seal to prevent moisture, humidity, dust and other external substances from entering.

[0031] The first protective cover 1 and the second protective cover 2 both include a base material layer 12, a water-proof layer 13, and a wear-resistant layer 14. The water-proof layer 13 is disposed on the surface of the base material layer 12, and the wear-resistant layer 14 is disposed on the surface of the water-proof layer 13. The first protective cover 1 and the second protective cover 2 can protect the cable joint. The water-proof layer 13 can isolate moisture and reduce the entry of moisture. The wear-resistant layer 14 can protect the first protective cover 1 and the second protective cover 2 and reduce the damage to the first protective cover 1 and the second protective cover 2 caused by external friction.

[0032] The substrate layer 12 is made of polyethylene, which has an extremely low water absorption rate and hardly absorbs water, thus effectively preventing moisture from entering the cable joint.

[0033] The waterproof layer 13 is made of polyvinyl chloride (PVC). PVC itself has excellent waterproof properties, which can effectively prevent external moisture, humidity and water vapor from entering the cable joint area. In addition, PVC has good resistance to most chemicals and environmental factors (such as salt spray, acid and alkali, etc.) and can be used in a variety of harsh environments.

[0034] Among them, the wear-resistant layer 14 is made of polyurethane. Polyurethane has excellent wear resistance. Compared with other plastic or rubber materials, polyurethane can better withstand external friction and wear. Polyurethane has good elasticity and flexibility, and can adapt to the shape changes of cable joints and external impacts.

[0035] The working principle of this embodiment is as follows: When using this cable joint moisture-proof cover, before connecting two cables, the operator puts the first protective cover 1 and the second protective cover 2 onto the surface of the two cables respectively, and then pulls the first protective cover 1 and the second protective cover 2 to allow the annular connecting plate 3 to enter the annular connecting groove 4. Then, the clamps 8 are locked to fix the first protective cover 1 and the second protective cover 2 to the two cables. After fixing, the operator can fix the first protective cover 1 and the second protective cover 2 together through the connecting flange 5. When using this cable joint moisture-proof cover, the water-proof layer 13 can isolate moisture and reduce the entry of moisture, and the wear-resistant layer 14 can protect the first protective cover 1 and the second protective cover 2 and reduce the damage to the first protective cover 1 and the second protective cover 2 caused by external friction. When the operator needs to inspect the joint, the operator can directly separate the connecting flange 5 to inspect the cable joint.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
