Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
It referring to Fig.1, is a kind of length self-interacting type cable disclosed by the invention, including 1 He of cable main body being wholely set
Cable intermediate 2, multiple cable intermediates 2 are equidistantly folded in cable main body 1 at interval.
Referring to Fig. 2, cable main body 1 includes leading body 11, and leading body 11 is the copper conductor for being enclosed with insulating layer, leading body 11
Successively package is provided with liner layer 12, armor 13 and oversheath 14 from inside to outside in outside.Cable main body 1 passes through multilayer protection pair
Leading body 11 plays a protective role.Multiple wires 15 are equipped in oversheath 14 along its length, wire 15 is preferably
Four and equiangularly arranged.The structural strength that can will reinforce cable main body 1 by wire 15, reduces its bending degree.
Referring to Fig. 2, cable intermediate 2 includes two connection rings 21, two connection rings 21 and the coaxial fixed company of oversheath 14
It connects, rubber bellows 22 is fixed between two connection rings 21, be provided in rubber bellows 22 and be electrically connected with leading body 11
Curved conductor 23, curved conductor 23 are arranged in " W " font, and curved conductor 23 is the copper conductor for being enclosed with insulating layer.Rubber bellows 22 are right
Curved conductor 23 plays a protective role.Therefore fix company of the end of wire 15 with connection ring 21 far from rubber bellows 22
It connects.The bending part of cable leans on cable intermediate 2 and completes.
Referring to Fig. 3, the armouring ring 24 of multiple head and the tail connections, armouring ring are provided between rubber bellows 22 and curved conductor 23
24 outer wall close to 21 one end of connection ring is fixed with outer ring 25, and the inner wall of the other end, which is fixed with, is clamped the inner ring being adapted to outer ring 25
26.Multiple 24 front and back head and the tail of armouring ring connect, and by the cooperation of outer ring 25 and inner ring 26, realize the continuity of armouring ring 24, into
One step forms curved conductor 23 and protects.The diameter of armouring ring 24 becomes larger as the spacing of its connection ring 21 becomes remote, two connections
The diameter of the armouring ring 24 of 21 middle of ring is maximum.Adjacent armouring ring 24 can be mutually inserted storage, and closely connection and not
Interruption.
Referring to Fig. 2, the side of connection ring 21 towards the curved conductor 23 is coaxially fixed with fixed ring 28, and fixed ring 28 is located at
Between armouring ring 24 and curved conductor 23, the outer diameter of fixed ring 28 is less than the minimum diameter of armouring ring 24, between two connection rings 21
It is provided with elastic webbing 27, elastic webbing 27 is cylindrical in shape, and the end of elastic webbing 27 is fixed with fixed ring 28 far from one end of connection ring 21
Connection.It can be played a protective role to the end of curved conductor 23 by fixed ring 28, prevent armouring ring 24 during cable folding right
Curved 23 outer wall of conductor causes to damage, and improves the structural strength of cable.After no external force, elastic webbing 27 facilitates among cable
The recovery of body 2.
Referring to Fig. 3, inert gas is filled between rubber bellows 22 and curved conductor 23, inert gas is nitrogen.
When cable intermediate 2 is bent or is pressurized, cable intermediate 2 makes rubber bellows 22 quickly extensive by air pressure inside
It is multiple, while inert gas is safer, and nitrogen obtains simple, cost performance height.Gas distribution channel 29 is offered in connection ring 21, it is defeated
Gas channel 29 is in " L " font, and 29 one end of gas distribution channel is in 21 peripheral wall of connection ring, and the other end is in 21 peripheral wall of connection ring.Gas distribution channel
29 are fixed with air valve 30 at 21 outer wall of connection ring, and gas distribution channel 29 is directed toward in rubber bellows 22 far from one end of air valve 30
Portion.Inert gas is sent into rubber bellows 22 from the gas distribution channel 29 of a connection ring 21, from the defeated of another connection ring 21
Gas channel 29 is discharged, and is sealed by air valve 30, so that ventilation is simple, it is also more convenient to operate.
It the implementation principle of the present embodiment and has the beneficial effect that
In cable use process when tension, 1 length of cable main body is constant, and cable intermediate 2 extends, at this point, two connection rings
Rubber bellows 22 between 21 can be elongated, and curved conductor 23 is straightened, so that the entire length of cable is increased, in no external force
After effect, elastic webbing 27 facilitates the recovery of cable intermediate 2.When being bent in cable use process, the bending of cable intermediate 2
Degree is higher than cable main body 1, realizes quick bending by cable intermediate 2.
Cable is made of cable intermediate 2 and cable main body 1, and on the one hand the setting of cable intermediate 2 realizes cable long
The automatic adjustment of degree improves applicability, avoids the fracture of cable to be suitable for different working environments, on the other hand, electricity
Cable intermediate 2 can free folding, bending amplitude be much larger than cable main body 1, surface is not easily broken.The present invention is more steady when using
It is highly-safe when determining, while using.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
