Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, a sealing waterproof structure between a cable and a sealed body is applied to the sealed body 1, a cable hole 2 for the cable 3 to pass through is formed in a side wall of the sealed body 1, a foaming layer 4 is arranged on the surface of the cable 3 penetrating through the cable hole 2, a sealing adhesive layer 5 is arranged on the surface of the foaming layer 4, and the sealing adhesive layer 5 is connected with the inner wall of the cable hole 2 in a sealing manner.

According to the sealing waterproof structure between the cable and the sealed body, the foaming layer 4 is arranged on the cable corresponding to the wire hole 2, the sealing adhesive layer 5 is arranged on the foaming layer 4, so that gaps between the cables 3 penetrating through the wire hole 2 and between the cables 3 and the wire hole 2 are filled, a sealing effect is formed, rainwater is prevented from entering the sealed body 1 along the cables 3, the sealing effect is good, stability and reliability are realized, the sealing can be realized without disassembling the cable, the cost is low, and the later maintenance or disassembly is convenient.

In one or more embodiments of the present invention, the foaming layer 4 is solidified and formed by spraying a foaming agent. The foaming agent is a conventional material, has low fluidity and low cost, can form a sealing bottom layer in a short time, has certain heat resistance (the temperature resistance is higher than 60 ℃), can fill most gaps between the cables 3 and between the cables 2 and the wire holes 3, and can support the sealant layer before the sealant layer is dried.

In one or more embodiments of the present invention, the sealant layer 5 is formed by drying and coating a high temperature pouring sealant. The high-temperature pouring sealant is liquid at normal temperature, has good fluidity and good hydrophobicity, can permeate into each gap, and can be molded after standing in air for a period of time to form a stable and firm waterproof sealing surface.

It should be noted that, in practice, the surface of the foaming layer 4 is provided with the sealant layer 5, here, the sealant layer 5 may be disposed on the front surface of the foaming layer 4, or may be disposed on the real surface and the side surface of the foaming layer 4 (wrapping arrangement), so as to further enhance the waterproof effect.

In one or more embodiments of the present invention, the sealing and waterproof structure between the cable and the sealed body further includes a sheath layer 6, the sheath layer 6 is disposed on the surface of the cable 3, and the wire hole 2 corresponds to the middle of the sheath layer 6. Through setting up restrictive coating 6, on the one hand can be to cable 3 go up corresponding to the position department in line hole 2 carries out further protection, and on the other hand more conveniently demolishs, changes when later maintenance.

In one or more embodiments of the present invention, the waterproof sealing structure between the cable and the sealed body further includes a sealing ring 7, the sealing ring 7 is disposed on the inner wall of the wire hole 2, and the sealing adhesive layer 5 is connected to the sealing ring 7 in a sealing manner. Through the arrangement of the sealing ring 7, the sealing performance of the sealing adhesive layer 5 and the inner wall of the wire hole 2 is better, and the sealing adhesive layer is convenient to remove during later maintenance and then reseal.

The installation process of the sealing waterproof structure between the cable and the sealed body is as follows:

1. firstly, arranging the sheath layer 7 at a position corresponding to the cable 3, wherein the specific position can refer to the position of the cable 3 relative to the cable hole 2 after installation;

2. arranging a sealing ring 7 on the inner wall of the wire hole 2;

3. and (3) coating the space between the cable 3 and the wire hole 2 by using a glue gun, and uniformly coating. A sealed bottom layer is formed, the foaming agent is easy to remove, and certain sealing and waterproof functions are achieved;

4. after the foaming agent is stably formed, high-temperature pot sealing glue is added between the surface of the foaming agent and the inner wall of the line hole 2, and the high-temperature pot sealing glue is liquid when being just put into the air, has good liquidity and can permeate into each gap. (if the foaming glue is not used, the high-temperature pot sealing glue is difficult to stay at the cable and the cable hole, and cannot be molded just like water.)

5. After the whole body is kept still for drying, the filling position is corrected, and the cable incoming line sealing requirement can be met.

The whole technical effect is as follows:

1. the construction is convenient, and the cable can be sealed without disassembling;

2. the sealing effect is good, and the liquid colloid can seal the gap, so that the sealing structure is stable and reliable;

3. the cost is low, the cost of the foaming adhesive is low, the water-based high-temperature tank sealing adhesive is expensive, and the use amount of the water-based high-temperature tank sealing adhesive can be reduced by adopting the combination of the two types of the foaming adhesive and the water-based high-temperature tank sealing adhesive, so that the cost is low;

4. and later maintenance or disassembly is facilitated. If there is demands such as electronic box aversion in the later stage, this seal structure can demolish fast, the change of the cable of being convenient for, dismantlement etc..

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
