[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0023] The utility model provides technical schemes: as Figure 2 , Figure 3 and Figure 4 indicated, in the embodiment, a water-resistant electromagnetic wire includes a conductor 1, characterized in that: the outer wall of the circumference of the conductor 1 is provided with an insulating layer 2, the outer wall of the circumference of the insulating layer 2 is provided with a water-blocking belt 3, the water-blocking belt 3 is spirally arranged, the water-blocking belt 3 is externally provided with a protective layer 4, and the outer wall of the circumference of the protective layer 4 is coated with waterproof glue 5.

[0024] The waterproof glue 5 of the outermost layer of the electromagnetic wire can increase the waterproof performance thereof, avoid the protective layer 4 on the inside from being affected by external factors, and when the waterproof glue 5 and the protective layer 4 are aged and cracks are generated with the increase of use time, after external water enters the cracks and contacts the water-blocking belt 3, the part of the water-blocking belt 3 in contact with the water will expand to fill the cracks, thereby effectively preventing the external water from continuously flowing inward.

[0025] As Figure 4 indicated, the outer wall of one end of the bottom of the water-blocking belt 3 is provided with a groove 301, and the outer wall of the other end of the water-blocking belt 3 is provided with an extension strip 302, and the extension strip 302 can enter the groove 301.

[0026] The inner wall of the top of the groove 301 is provided with a glue layer 303, and the glue layer 303 is double-sided adhesive, which can make the connection state of the water-blocking belt 3 more firm and not generate gaps due to random deviation.

[0027] When the water-blocking belt 3 is wrapped, as long as one end thereof is first placed obliquely, then operated, and the extension strip 302 of the one end is aligned and enters the groove 301 of the other end, the wrapped water-blocking belt 3 can be ensured to form a whole and not reduce the use effect due to the generation of gaps.

[0028] As Figure 1 and Figure 3 indicated, the waterproof glue 5 is externally wrapped with a felt layer 6, and the felt layer 6 is slidably inserted with a connecting pin 7 at both ends.

[0029] The bottom of the connecting pin 7 is provided with a barb on the outer wall of the pin shaft circumference, facilitating the connection of the connecting pin 7 and not being blocked, but not easily separated from the felt layer 6, which is conducive to improving the connection effect.

[0030] The felt layer 6 is wrapped on the outermost part of the electromagnetic wire, and then the two ends of the felt layer 6 are connected by the connecting pin 7, so as to achieve the effect of isolating external heat.

[0031] As shown in Figure 3 , the protective layer 4 is made of PE material, which is a kind of high-density polyethylene with the characteristics of waterproof, moisture-proof, acid and alkali corrosion resistance, and good low-temperature toughness and flexibility, so that the electromagnetic wire is more flexible.

[0032] As shown in Figure 1 and Figure 3 , the felt layer 6 is made of ceramic fiber felt material, which is a kind of light, soft, heat-resistant and corrosion-resistant material with a temperature resistance of more than 1000℃.

[0033] The utility model provides a kind of water-resistant electromagnetic wire, specific working principle as follows:

[0034] When the device works, the felt layer 6 is wrapped on the outermost part of the electromagnetic wire, and then the two ends of the felt layer 6 are connected by the connecting pin 7, so that the felt layer 6 can form a whole barrel, and a barrier can be formed outside the electromagnetic wire, to prevent external temperature from penetrating into the electromagnetic wire. The waterproof adhesive 5 on the outermost layer of the electromagnetic wire can increase its waterproof performance, and the protective layer 4 inside is not affected by external factors. As the use time increases, when the waterproof adhesive 5 and the protective layer 4 are aged and cracks occur, the water outside enters the cracks and contacts the water-blocking belt 3, and the part of the water-blocking belt 3 in contact with the water will expand to fill the cracks, effectively preventing the water from flowing inward. When the water-blocking belt 3 is wrapped, it is only necessary to place one end obliquely first, then operate, and make the extension strip 302 of one end align with the groove 301 of the other end, so that the wrapped water-blocking belt 3 can form a whole, without gaps to reduce the use effect. The insulating layer 2 can provide the last protection to prevent the water outside from contacting the inner conductor 1 and affecting the use performance of the conductor 1.
