The sub-clip is concave and the female ferrule is convex.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in the process of protecting the cables, the above-mentioned devices lack insulation and corrosion-resistant structures for the cable body, which causes the internal part of the cables to be affected by low temperatures when encountering harsh environments underground, thereby affecting the normal operation of the cables. Based on this, the present utility model applies for the design of a cold-resistant cable protective cover. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a cold-resistant cable protective cover.

At the same time, the aerogel pad has very low thermal conductivity and excellent thermal insulation performance, which can improve the thermal insulation performance of the inside of the cable body.

[0008] Furthermore, the corrosion-resistant layer includes an aramid layer.

[0009] Furthermore, a silicone sleeve is bonded to the outer surface of the aramid layer.

[0010] By adopting the above technical scheme, through the combination of the aramid layer and the silicone sleeve, it has strong corrosion resistance and wear resistance, which can make the cable body have better corrosion resistance and chemical resistance when underground, thereby making the cable body more stable when working underground.

[0011] Furthermore, metal cable ties are provided on both sides of the outer surface of the silicone sleeve.

[0012] Furthermore, fasteners are provided on the outer surfaces of the two metal cable ties.

[0013] By adopting the above technical solution, the metal tie and the fastener cooperate to seal the two sides of the corrosion-resistant layer from the cable body, thereby preventing liquid from entering the interior of the cable body.

[0014] Furthermore, the aerogel pad is sealed and bonded to the cable body.

[0015] Furthermore, the silicone sleeve and the aerogel pad are sealed and fitted.

[0016] By adopting the above technical solution, the impact resistance of the cable body can be improved through the high resilience of the aerogel pad and nitrile rubber particles.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. In the present application, by setting up the thermal insulation layer and coating the nitrile rubber particles inside the aerogel pad, the impact resistance of the cable body can be improved, and the inside of the cable can be protected from the impact of external factors, which may cause the internal cable to deform and affect its normal use. At the same time, the aerogel pad has very low thermal conductivity and excellent thermal insulation performance, which can improve the thermal insulation performance of the cable body, thereby achieving the purpose of heat preservation and cold resistance of the cable body;

[0019] 2. In the present application, by setting up the corrosion-resistant layer and combining the aramid layer with the silicone sleeve, it has strong corrosion resistance and wear resistance, which can make the cable body have good corrosion resistance and chemical resistance when underground, thereby making the cable body more stable when working underground. At the same time, the silicone sleeve has good sealing performance, which can prevent rain and snow water from invading the interior of the cable body, thereby improving its service life.
