Background technique
Because helicopter tail rotor revolving speed is high, radius of turn is big, the centrifugal action that the cable for tail-rotor leaf electrical communications is subject to
Obviously, each layer structure of cable is easy to happen abrasion or breakage problem after a period of use.Also, become to adapt to tail-rotor leaf
Away from the cable length should there are surpluses, inconvenience to be completely fixed in tail-rotor structure, has been further exacerbated by the use condition of cable, has led
It sends a telegraph cable to be under frequent vibration environment, cable wear problem is more prominent.It is asked to solve the reliability after long-time use
Topic, needs to design a kind of applicable construction of cable.
Summary of the invention
Goal of the invention: the present invention provide one kind can the high-speed rotating construction of cable, can solve cable centrifugalization and easily grind
The problem of damage or fracture.
One kind can the high-speed rotating construction of cable, connector and bundle conductor including end, in the bundle conductor outer sheath
Equipped with aramid fiber wired tube, spring is housed in aramid fiber wired tube outer sheath, is set with oversheath in spring outwards, the spring and outer shield
Set is an integral structure, and two ends of spring are connect with connector；Appropriate location is coated with bonding agent, bonding in connector
The spring and aramid fiber wired tube.
One kind can the high-speed rotating construction of cable, have bundle conductor, the construction of cable an end have connector, separately
One end is directly connect with equipment, and aramid fiber wired tube is housed in the bundle conductor outer sheath, is set on the outside of aramid fiber wired tube
Have spring, be set with oversheath in spring outwards, the spring and oversheath are an integral structure, an end of spring with connect
Device connection, another end is connect with equipment；Appropriate location is coated with bonding agent in connector, is bonded the spring and aramid fiber
Wired tube；Appropriate location is coated with bonding agent in equipment, and the oversheath, aramid fiber wired tube and bundle conductor, which are staggered, to be stretched out and glue
It connects in equipment.
The connector is plug.
Tail attachment is housed on the plug, is connect with the spring, and is bonded the aramid fiber in tail accessory internal and compiles
Knit set.
Central region is further sleeved with pyrocondensation around pipe on the outside of oversheath, connect with structure revolving part.
It is further sleeved with rubber ring in the end close to equipment, is fixedly connected with equipment.
The oversheath uses polytetrafluoroethylhelix helix tube or heat-shrinkable T bush.
The spring uses 65Mn spring steel.
Thermal shrinkable sleeve pipe sleeve plays protective action on tail attachment, and end prevents cable attached with tail beyond 20 ± 2mm of tail attachment
Part end forms stress and concentrates.
The utility model has the advantages that the invention proposes one kind can the high-speed rotating construction of cable, by the way that spring is arranged in oversheath,
Prevent oversheath from deforming；By in tail attachment end setting heat, around casing, rubber ring being arranged in component end, stress is avoided to concentrate；It is logical
Setting aramid fiber wired tube is crossed, drawing-resistant function is played.The cable has preferable wearability, pull resistance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of cable of the present invention.
Wherein 1: plug, 2: tail attachment, 3: heat-shrinkable T bush, 4: oversheath, 5: spring, 6: aramid fiber wired tube, 7: bundle conductor,
8: rubber ring, 9: bonding agent, 10: pyrocondensation is around pipe
Specific embodiment
The present invention is described in further details with reference to the accompanying drawings of the specification.
As shown in Figure 1, one kind can the high-speed rotating construction of cable, spring 5 including oversheath 4, in oversheath 4,
Aramid fiber wired tube 6, bundle conductor 7, cable one end are fixed on inside rotary part using rubber ring 8, are connected with transmission line in component
It connects, the other end is fixed by spring carrier arm and the cooperation of tail attachment 2, and plug 1 connect transmission electric energy with other components.Wherein, cable
Both ends are all made of 9 fixed spring 5 of bonding agent, aramid fiber wired tube 6, bundle conductor 7, and tail attachment 2 is protected using heat-shrinkable T bush 3, cable
It is fixed around pipe 10 that middle position can cover pyrocondensation.
The oversheath 4 uses polytetrafluoroethylhelix helix tube or heat-shrinkable T bush, to guarantee the environmental suitability of cable.
The spring 5 uses 65Mn spring steel, one end and tail attachment 2 by mechanical engagement, and both ends are all made of bonding agent
Fixation is locking.
The spring 5 and 4 reliable fit of oversheath, play a supportive role, prevent oversheath from deforming.
The aramid fiber wired tube 6 is fitted closely with bundle conductor, and both ends are fixed by bonding agent 9, is played drawing-resistant function, is prevented electricity
Broken in cable rotary course.
The bundle conductor 7 uses finished product cable structure, to guarantee all conducting wire entirety stress.
Cable one end is fixed on inside rotary part using rubber ring 8, guarantees to seal using bonding agent 9.
Cable one end connect transmission electric energy, fast demountable with other components using plug 1.
3 sets of heat-shrinkable T bush are played protective action on tail attachment 2, and end prevents cable and tail beyond 20 ± 2mm of tail attachment
Attachment end forms stress and concentrates.
The present invention prevents oversheath from deforming by the way that spring is arranged in oversheath；By hot around set in the setting of tail attachment end
