[0002] During the on-site construction of electric power, after laying the secondary cables and stripping the cables, it is necessary to insulate and waterproof the joints between the cables.

[0003] The structure of a cable usually includes at least one cable wire inside and an insulating layer sleeved outside the cable wire. Currently, the insulating and waterproof treatment for cable wire joints mainly uses the method of binding with insulating tape. The specific operation process is as follows: First, wrap the cable wire joint with non-adhesive insulating tape; after it is basically flush with the outer diameter of the cable insulating layer, then replace it with adhesive insulating tape for secondary fixed binding.

[0004] During the whole operation process, only using insulating tape to wrap the cable wire joint for waterproofing easily leads to poor adhesion tightness between the insulating tape and the cable insulating layer, which easily causes moisture to penetrate from the position where the insulating tape is adhered to the cable insulating layer, thus resulting in poor waterproof effect of the cable. Content of the Utility Model

[0005] Based on this, in view of the problem of poor waterproofness of the insulating tape for cables, it is necessary to provide an insulating and waterproof structure.

[0006] An insulating and waterproof structure includes a fastening layer and an insulating and waterproof layer. The fastening layer is used to fasten the cable wire joint.

The outer layer of the filling part is connected to the inner layer of the waterproof part, and the inner layer of the filling part is connected to the outer layer of the connecting part.

[0011] In one embodiment, the length of the waterproof part is greater than the length of the filling part.

[0012] In one embodiment, the width of the waterproof part is greater than the width of the filling part.

[0013] In one embodiment, the thickness of the filling part is greater than the thickness of the waterproof part.

[0014] In one embodiment, a notch is formed in the outer layer of the insulating waterproof layer, and the opening divides the notch into two equal parts.

[0015] In one embodiment, the surface of the notch has an anti-slip layer.

[0016] In one embodiment, the fastening opening is adapted to the position of the opening.

[0017] In the above-mentioned insulating and waterproof structure, through the cooperative setting of the fastening layer and the insulating waterproof layer, the fastening layer includes a connecting part and a fastening part.

On the contrary, when an element is referred to as being "directly" connected to another element, there is no intermediate element.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer to Figure 1 and Figure 2 , an insulating and waterproof structure, including a fastening layer 1 and an insulating and waterproof layer 2. The fastening layer 1 is used for fastening a cable joint. The insulating and waterproof layer 2 is sleeved on the outer layer of the fastening layer 1. Two sealing and waterproof parts 21 are symmetrically arranged at both ends of the insulating and waterproof layer 2. A first bonding surface 211 is arranged on the inner layer of each of the two sealing and waterproof parts 21. The two sealing and waterproof parts 21 are used for respectively bonding to the outer layer 3 of the cable insulating layer;

[0024] The fastening layer 1 includes a connecting part 11 and a fastening part 12. The connecting part 11 is installed on the inner layer of the insulating and waterproof layer 2. One end of the fastening part 12 is connected to the connecting part 11. The fastening part 12 is an elastic member. The connecting part 11 is provided with a through fastening opening 111. The other end of the fastening part 12 passes through the fastening opening 111 and wraps the cable joint. One end of the insulating and waterproof layer 2 has an opening 22. Both sides of the opening 22 have a second bonding surface 221.

[0025] The inner layer of the connecting part 11 is provided with a third bonding surface 112. The length of the fastening layer 1 is less than the length of the insulating and waterproof layer 2. The position of the fastening opening 111 is adapted to the position of the opening 22, so that an open end corresponding to the position of the opening 22 is formed between the connecting part 11 and the fastening part 12.

[0026] The fastening part 12 is an elastic member, which itself has a certain elasticity to tighten towards the fastening layer 1. The first adhesive surface 211, the second adhesive surface 221 and the third adhesive surface 112 are usually covered with anti-sticking paper in the non-use state, and the anti-sticking paper can be torn off from the first adhesive surface 211, the second adhesive surface 221 and the third adhesive surface 112 during use. When the other end of the fastening part 12 is not inserted through the fastening opening 111, an open end will be formed between the connecting part 11 and the fastening part 12. The open end can allow the cable joint wrapped with insulating tape to enter the connecting part 11 and the fastening part 12. After the other end of the fastening part 12 is inserted through the fastening opening 111, a cylindrical structure is formed with the connecting part 11. The diameter of the cylindrical structure is slightly smaller than the diameter of the cable joint wrapped with insulating tape, so that the fastening layer 1 wraps the cable joint wrapped with insulating tape more tightly.

[0027] It can be understood that the diameter of the cable joint wrapped with insulating tape is smaller than the diameter of the cable wrapped with the outer layer 3 of the cable insulating layer, and the outer diameter of the cable wrapped with the outer layer 3 of the cable insulating layer is adapted to the inner diameter of the insulating and waterproof layer 2.

[0028] When insulation and waterproof treatment are required for the joint between cables, the insulating and waterproof layer 2 is opened from the opening 22, and then the connecting part 11 and the fastening part 12 are opened from the open end. The cable joint wrapped with insulating tape enters the fastening layer 1 in sequence from the opening 22 and the open end. After the other end of the fastening part 12 is inserted through the fastening opening 111, since the fastening part 12 is an elastic member and itself has a certain elasticity to tighten towards the fastening layer 1, the connecting part 11 and the fastening part 12 can tightly wrap the cable joint wrapped with insulating tape. At this time, the two sealing and waterproof parts 21 at both ends of the insulating and waterproof layer 2 are sleeved on the outer layer 3 of the cable insulating layer. The anti-sticking paper on the first adhesive surface 211 and the second adhesive surface 221 of the sealing and waterproof part 21 is removed, so that the first adhesive surface 211 is adhered to the outer layer 3 of the cable insulating layer, and the two second adhesive surfaces 221 are adhered to each other, so that the insulating and waterproof structure is fixed between the cables. Since the first adhesive surface 211 of the sealing and waterproof part 21 is adhered to the outer layer 3 of the cable insulating layer, it is not easy for external moisture and liquid to enter the interior of the insulating and waterproof structure through the gap between the first adhesive surface 211 of the sealing and waterproof part 21 and the outer layer 3 of the cable insulating layer.

[0029] Furthermore, in order to fix the cable joint wrapped with insulating tape more firmly in the fastening layer 1, a third adhesive surface 112 is provided on the inner layer of the connecting part 11. By adhering the cable joint wrapped with insulating tape to the third adhesive surface 112, the cable joint wrapped with insulating tape is fixed more firmly in the fastening layer 1.

[0030] In this way, an insulating and waterproof structure is provided. Through the cooperative arrangement of the fastening layer 1 and the insulating and waterproof layer 2, the fastening layer 1 includes a connecting portion 11 and a fastening portion 12. Two sealing and waterproof portions 21 are symmetrically arranged at both ends of the insulating and waterproof layer 2. First, wrap the cable joint with a sticky insulating tape so that the insulating tape completely wraps the cable joint. Then, sequentially open the insulating and waterproof layer 2 and the fastening layer 1 from the outside, place the cable joint wrapped with the insulating tape in the fastening layer 1, wrap the cable joint wrapped with the insulating tape through the cooperation of the connecting portion 11 and the fastening portion 12, and bond the two sealing and waterproof portions 21 to the cable insulating layer 3 to prevent moisture from seeping into the cable joint. Then, bond the second bonding surfaces 221 on both sides of the opening of the insulating and waterproof layer 2 to each other, and the fixing of the insulating and waterproof structure can be completed. This not only achieves the insulating and waterproof effect but also makes the installation simpler and more convenient.

[0031] In one of the embodiments, the insulating and waterproof layer 2 further includes a waterproof portion 23 and a filling portion 24. The outer layer of the filling portion 24 is connected to the inner layer of the waterproof portion 23, and the inner layer of the filling portion 24 is connected to the outer layer of the connecting portion 11. The length of the waterproof portion 23 is greater than the length of the filling portion 24, the width of the waterproof portion 23 is greater than the width of the filling portion 24, and the thickness of the filling portion 24 is greater than the thickness of the waterproof portion 23.

[0032] In this way, the filling portion 24 can be adhesively connected to the inner layer of the waterproof portion 23 and the outer layer of the connecting portion 11 respectively. The waterproof portion 23 is made of insulating waterproof material, and the filling portion 24 can be made of a soft material, which can play a good role in connecting the waterproof portion 23 and the connecting portion 11.

[0033] In one of the embodiments, a notch 25 is formed on the outer layer of the insulating and waterproof layer 2. The opening 22 divides the notch 25 into two equal parts, and the surface of the notch 25 has an anti-slip layer.

[0034] In this way, through the setting of the notch 25, when opening the insulating and waterproof layer 2 from the opening 22, fingers can hold the notch 25 part, and the insulating and waterproof layer 2 can be opened from the opening 22. Moreover, by setting an anti-slip layer on the surface of the notch 25, the anti-slip layer can increase the friction force in contact with the hand, making it more labor-saving to pull the insulating and waterproof layer 2 from the opening 22.

[0035] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0036] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
