Embodiment
Below in conjunction with Fig. 1-2, the present invention is described in detail.
According to embodiment, a kind of cable of the heat shield cover with heat extraction hole and wearing layer, comprise the columniform cable body 9 be placed in described heat shield cover and the described heat shield cover comprising heat shield cover 8 and lower heat shield cover 7, the cover wall of described upper heat shield cover 8 and lower heat shield cover 7 includes respective diapire 80, 70 and be positioned at diapire 80, the sidewall of 70 both sides, described diapire 80, 70 respectively with the contacting at two diametrically relative circular top parts of described cable body 9, the cooling channels 81 extended along described cover wall is provided with all separately in described cover wall, 71, at described diapire 80, be provided with in 70 and described cooling channels 81, the 71 heat extraction holes 200 paralleled, described heat extraction hole 200 is provided with more than 21 and 21, described heat extraction hole 200 is provided with 21 in the present invention in order to reduce the heat that a part of described cable body 9 in use distributes, play the effect of quick heat radiating, the outer surface of the cover wall of described upper heat shield cover 8 and lower heat shield cover 7 is provided with wearing layer 73, described wearing layer 73 is in order to prevent described heat shield from covering on installation and be worn in moving thus serve wear-resistant protection effect to described cable body 9, wherein, two sidewalls of described lower heat shield cover 7 are inserted between two sidewalls of described upper heat shield cover 8, and the cooling channels 71 in the sidewall of described lower heat shield cover 7 is overlapping on the bearing of trend of described sidewall with the cooling channels 81 in the sidewall of described upper heat shield cover 8, two sidewalls of described lower heat shield cover 7 are respectively arranged with and comprise body extension 35, the lower locking member 3 of the protuberance 32 protruded from the middle part of described body extension 35 and the first sticking department 38 at the end of described body extension 35, wherein, the other end relative with the described end that described first sticking department 38 connects of described body extension 35 and the diapire 70 of described lower heat shield cover 7 adjoin, first side of described protuberance 32 abuts with the end of the sidewall of described lower heat shield cover 7, second side of described protuberance 32 is provided with lower cushion 33, two sidewalls of described upper heat shield cover 8 pass through the array 82 of the fixing protrusion arranged along the bearing of trend of sidewall and is removably fixedly installed the stationary body portion 45 that comprises, and the upper locking member 4 of the second sticking department 48 of end in described stationary body portion 45, described upper locking member 4 can the array 82 along described fixing protrusion adjusts position to adapt to the cable body 9 of different-diameter by the joint of array 82 with described fixing protrusion thus, the end of the second sticking department 48 is provided with the upper cushion 43 abutted with described lower cushion 33, described first sticking department 38 comprises successively by the first inclined plane part 31, what the planar portions 34 parallel with the bearing of trend of described sidewall and the First shoulder 312 for locking joint formed first locks profile, described second sticking department 48 comprise successively by locking process with the second inclined plane part 41 of described first inclined plane part 31 and described planar portions 34 slip joint and for engage to be formed with described First shoulder 312 when having locked lock that the second shoulders 412 of being connected forms second lock profile, wherein, described second shoulders 412 is provided with the locking projected in the lock recess of indent the plane of described First shoulder 312 from the plane of described second shoulders to protrude, thus, utilize the strain of described lower cushion 33 and described upper cushion 43, thus described locking protrusion can be realized with the locked engagement of described lock recess and can described lower cushion 33 and described upper cushion 43 be passed through when needed to compress and realize throwing off.
Valuably, the material of described heat shield cover is flexible, such as, for containing elastomeric material.
