Aviation wire harnesses are widely applied to various parts of aircrafts such as airplanes and the like, play an important role on the aircrafts, and particularly, since the aircrafts start to enter electrification, the wire harnesses are increasingly subjected to more and more tasks, thereby not only being responsible for the traditional power transmission and distribution function, but also being responsible for the information transmission function of important systems such as flight control, engines, landing gears, avionics and the like. The aviation wiring harness wiring system must ensure resistance against external electromagnetic interference and prevent energy radiation of internal transmission signals to the outside. With the rapid development of the cable harness industry in recent years, higher demands are made on the diversification of the harness structure. The existing aviation special wire harness structure can not meet the use requirements in the aspects of water resistance, dust prevention, electromagnetic shielding and environment resistance.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a can satisfy under environment such as dustproof, vibration, rain-proof, have good shielding, sealed, fixed performance's pencil structure.
In order to achieve the above object, the utility model adopts the following technical scheme: the waterproof cable comprises a cable, a plug connector and a waterproof gland head, wherein one end of the cable is connected with the waterproof gland head, and the other end of the cable is connected with the plug connector through a tail accessory;
the tail accessory comprises a sealing joint and a switching nut, wherein a first shielding ring is arranged in the sealing joint, the switching nut is connected to the left side of the sealing joint, a sealing rubber ring is arranged between the sealing joint and the switching nut and used for improving the waterproof sealing performance, and a plug connector is connected to the left side of the switching nut.
Waterproof glan head includes that ring flange, rubber circle, second shield ring, rubber seal joint and metal afterbody link the cap, the ring flange both sides are helicitic texture, and are close to plug connector one side and are fixed with the rubber circle, second shield ring, rubber seal joint and metal afterbody link the cap suit in proper order in the cable periphery, and the insulating skin is got rid of to the cable in ring flange and second shield ring.
The cable adopts a flame-retardant cabling wire.
The maximum range of the outer diameter of the cable is 10.8-12 mm.
The sealing joint is made of metal materials.
Use the utility model discloses a beneficial effect is: the utility model discloses chooseed for use threaded connection's sealing joint, can carry out the lectotype according to imperial system screw thread or metric system screw thread and fix at required installation position, sound construction. The sealing ring is added at the threaded connection part of the sealing joint, so that the waterproof sealing performance is improved. A domestic cable forming wire is selected, the maximum outer diameter of the wire is phi 10.8-phi 12mm, interference fit with the HSM-EMV series sealing joint is achieved, and meanwhile, the rubber sealing joint is screwed and extruded through threads to achieve a sealing effect. The shielding connection shell of the cabled conductor is realized through the shielding ring in the sealing joint. The product structure can be designed into the structure of the wire outlet of the connector tail accessory according to actual needs, and the wire outlet can be connected with different connectors through front end threads, so that the effects of sealing and fixing a wire harness are achieved.
