Abstract
The utility model discloses a thermal deformation self-adaptive cable shield which is used for protecting cables on the surface of an aircraft. The cable shield comprises a cable housing, wherein, a waist-shaped mounting hole is formed on the cable housing and covered by a hard gasket; the cable housing is connected with a corner cube through a T-shaped stop screw which sequentially penetrates the hard gasket and the waist-shaped mounting hole; the corner cube is fixed on a support structure on the surface of the aircraft; and a gap between the waist-shaped mounting hole and the T-shaped stop screw form the thermal deformation compensation space of the cable shield. The thermal deformation self-adaptive cable shield is proved to have the advantages of simple structure, convenience in installation, and favorable protection effect.
Description
Technical field
The utility model belongs to the Flight Vehicle Structure technical field, specifically is meant a kind of thermal deformation self-adapting type cable cover.
Background technology
The cable that is arranged on aircraft supporting construction outer surface need adopt the cable cover to protect.In the flight course of aircraft when high speed, long boat, the cable cover receives pneumatic thermal impact, can produce bigger thermal deformation, and the contact site of cable cover self and cable cover and aircraft all can produce the crack, thereby influences its defencive function to cable.For overcoming the influence of thermal deformation, have and select the higher material preparation cable cover of thermal stress adapting to the thermal deformation demand, but the type selecting of its material and use very harshly, cost is high; Also have in the outside safeguard measure that increases of cable cover and reduce thermal stress, but its safeguard measure structure complicacy be unfavorable for installing, even can disturb the normal operation of aircraft.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, easy for installation, thermal deformation self-adapting type cable cover that protection effect is good.
For realizing above-mentioned purpose; The thermal deformation self-adapting type cable cover of the utility model; Be used to protect the cable that is arranged on the aircraft surface, it comprises the cable case, offers waist shape installing hole on the said cable case; Be coated with hard gasket on the said waist shape installing hole; Said cable case links to each other with hornblock through the T shape stop screw that passes hard gasket and waist shape installing hole successively, and said hornblock is fixed on the supporting construction of aircraft surface, and the gap between said waist shape installing hole and the T shape stop screw constitutes cable cover thermal distortion compensation space.
Further, be provided with elastic washer between said T shape stop screw and the hard gasket, can strengthen the sealing effectiveness between hard gasket and waist shape installing hole.
Also further, the area of said hard gasket is bigger than the area of waist shape installing hole, can ensure effectively that hard gasket can cover the sealing of waist shape installing hole.
The useful technique effect of the utility model is:
Through adopting deformation-compensated mentality of designing; The installing hole of cable case is designed to the kidney slot structure; And form the gap between control waist shape installing hole and the T shape stop screw; This gap stays compensation space with the supporting construction of aircraft surface because of the different deformation quantity that expands with heat and contract with cold to cable case under the thermal environment, has avoided the cable case to receive destruction at flight course because of thermal stress.Simultaneously, the cable case is located by connecting through stop screw and aircraft supporting construction, has promptly guaranteed connection stability between the two, has ensured the compensation space between waist shape installing hole and the stop screw again.Cover hard gasket on the waist type installing hole and seal, guaranteed that cable cover junction do not have extraneous air-flow and get into.Having wide range of applications of the utility model can be satisfied the application of multiple Flight Vehicle Structure technical field, and it is simple and reliable for structure, bigger raising the production and the installation effectiveness of cable cover.
