Definitions
- the present application relates to the field of cables, and more particularly to a cable using a corrosion-resistant heat shield.
- Cables tend to emit a certain amount of heat during use. When the cable extends into the enclosed space with various electrical components, the heat is not dissipated and easily causes heat to accumulate, thereby posing a safety hazard.
- the present invention is directed to a cable using a corrosion-resistant heat shield which overcomes the above disadvantages.
- a cable using an anti-corrosion heat shield comprising a cylindrical cable body disposed within the heat shield and the same comprising an upper heat shield and a lower heat shield a heat shield having a bottom wall and side walls on both sides of the bottom wall
- the upper two opposite dome portions are in contact with each other, and each of the cover walls is provided with a cooling fluid passage extending along the cover wall, and outer surfaces of the upper heat shield and the lower heat shield cover wall
- Each of the layers of the corrosion-resistant material is sprayed to prevent the heat shield from being corroded to provide a corrosion protection function to the cable body to adapt to different environments, wherein the lower heat shield Two side walls of the cover are inserted between the two side walls of the upper heat shield, and a cooling fluid passage in the side wall of the lower heat shield and a side wall of the upper heat shield
- the cooling fluid passages overlap in the direction in which the side walls extend, and the two lower heat shields Provided on the side wall are respectively a lower locking member including a body extending portion, a protrud
- the heat shield can follow the bending curve of the cable body itself by the flexibility of the material; Moreover, the position adjustment of the upper locking member can accommodate cables of different diameters. And with the flow of cooling fluid (such as water) in the wall of the hood, the heat can be carried away in time.
- cooling fluid such as water
- the heat shield can overcome the elastic deformation of the elastic pad. The smoothing of the locking process can be ensured by the sequential engagement of the beveled and planar contours of the lower locking member with the contoured contour of the upper locking member, which ensures that the locking process is prevented from occurring when the locking occurs. Shock.

- the bottom walls 80, 70 are respectively in contact with the diametrically opposed two dome portions of the cable body 9, and each of the cover walls is provided with a cooling fluid passage 81, 71 extending along the cover wall.
- the outer surfaces of the cover wall of the heat shield 6 and the lower heat shield 7 are coated with a corrosion-resistant material layer 63 for preventing the heat shield from being corroded.
- the cable body 9 serves as a corrosion protection to accommodate different environments, wherein the two side walls of the lower heat shield 7 are inserted between the two side walls of the upper heat shield 8, and The cooling fluid passage 71 in the side wall of the heat shield 7 and the cooling fluid passage 81 in the side wall of the upper heat shield 8 are extended in the side wall Overhanging in the extending direction, the two side walls of the lower heat shield 7 are respectively provided with a protruding portion 32 including a main body extending portion 35 protruding from a central portion of the main body extending portion 35, and the main body a lower locking member 3 of the first locking portion 38 at the end of the extension 35, wherein the other end of the body extension 35 opposite the end of the first locking portion 38 is opposite to the
- the bottom wall 70 of the lower heat shield 7 is adjacent, the first side of the protrusion 32 abuts the end of the side wall of the lower heat shield 7, and the second side of the protrusion 32 is disposed.
- a lower elastic pad 33 having detachably fixedly disposed on the two side walls of the upper heat shield 8 by a fixed protruding array 82 arranged along the extending direction of the side wall, and An upper locking member 4 of the second locking portion 48 at the end of the fixed body portion 45, whereby the upper locking member 4 can be secured along the fixed arched array 82
