Condition.
It needs to be illustrated, the first cable 20 and the second cable 30 are the two sections of electricity formed after old cable is truncated
Cable, coaxial cable successively includes inner core 40, internal insulating layer, outer core 50 and external insulation from inside to outside, therefore connects inner core
It needs to carry out processing of bursting at the seams to cable before 40, so that inner core 40 exposes.In practical application, lengthwise of the inner core 40 along coaxial cable
The exposed length in direction is 40 millimeters to 60 millimeters.Preferably, inner core 40 is along the exposed length of the longitudinally of coaxial cable
50 millimeters.
Meanwhile for the coaxial cable of conveying high-pressure, the quantity of the inner core 40 inside each coaxial cable may be more,
Therefore using aluminium hydraulic pressed connecting pipe 12 connect the first cable 20 with when the inner core 40 of the second cable 30 can also first by corresponding inner core 40 together
It is being crimped after axis setting.
In addition, for the label of inner core 40 and outer core 50 in Fig. 1, since the first cable 20 and the second cable 30 are substantially

In some embodiments, aluminium hydraulic pressed connecting pipe 12 is copper pipe, so that the inner core 40 of the first cable 20 and the second cable 30
Inner core 40 be electrically connected by aluminium hydraulic pressed connecting pipe 12.Further, aluminium hydraulic pressed connecting pipe 12 is along the length of the longitudinally of coaxial cable than first
The sum of cable 20 and the exposed length of inner core 40 of the second cable 30 are small, that is to say, that aluminium hydraulic pressed connecting pipe 12 crimps the first cable 20 and second
The inner core 40 of cable 30, even if the inner core 40 of the first cable 20 and the second cable 30 abuts against in aluminium hydraulic pressed connecting pipe 12, it is only necessary to protect
The middle position for demonstrate,proving aluminium hydraulic pressed connecting pipe 12 is 40 abutted position of inner core of the first cable 20 and the second cable 30, so that it may so that aluminium hydraulic pressed connecting pipe 12
Both ends do not extend to the internal insulating layer of the first cable 20 or the second cable 30.
In practical application, the radial direction of the outer diameter of aluminium hydraulic pressed connecting pipe 12 less than the first cable 20 or the internal insulating layer of the second cable 30
Size.In this way, may make when the first safeguard structure 14 is arranged in the outside of aluminium hydraulic pressed connecting pipe 12, will not be formed at aluminium hydraulic pressed connecting pipe 12 excessive
Protrusion.It should be noted that since aluminium hydraulic pressed connecting pipe 12 is also conductive, and aluminium hydraulic pressed connecting pipe 12 does not cover all exposed inner cores 40
Lid, in order to ensure all inner core 40 and aluminium hydraulic pressed connecting pipe 12 are by insulation processing, therefore the both ends of the first safeguard structure 14 need to prolong
Extend to the internal insulating layer of the first cable 20 and the second cable 30, that is to say, that the first safeguard structure 14 has coated inner core 40 and has been located at
Part outside aluminium hydraulic pressed connecting pipe 12.
In some embodiments, the first safeguard structure 14 from the inside to the outside successively include insulating layer, waterproof layer, fireprotection layer and
Plastic layer, to ensure aluminium hydraulic pressed connecting pipe 12 and exposed inner core 40 and extraneous isolation completely, that is, realize outer core 50 and inner core 40 it
Between insulate, also prevent influence of the external environment to inner core 40.Further, insulating layer is insulating tape, and waterproof layer is waterproof
Adhesive tape, fireprotection layer are fire-proof belt, and plastic layer is PVC tape, and insulating tape laying is the built-in electrical insulation from the first cable 20
Layer is laid with always to the internal insulating layer of the second cable 30, and the adhesive tape test of other layers successively covers insulating tape.
In practical application, each layer of adhesive tape is overlap according to half wrapped, is being crimped with insulating tape
On pipe 12 it is wrapped for, by insulating tape around aluminium hydraulic pressed connecting pipe 12 1 circle after severing, then proceed to the pitch of the laps on aluminium hydraulic pressed connecting pipe 12, and latter
The one side edge of circle insulating tape is positioned at the middle position of previous circle insulating tape.In this way, one encloses from the first cable 20
Internal insulating layer extend to the internal insulating layer of the second cable 30
In some embodiments, conducting connecting part 16 has opposite first end and second along the circumferential direction of aluminium hydraulic pressed connecting pipe 12
End, is spaced a prepsetting gap between first end and second end.Although conducting connecting part 16 is the outside for being sheathed on the first protective layer,
But conducting connecting part 16 and entirely around the first protective layer, that is to say, that if the first protective layer is cyclic annular, conducting connecting part
16 be not a complete cyclic structure, but a cyclic structure with fracture.In this way, efficiently avoiding connecting
After completing and being powered, conducting connecting part 16 forms vortex, thus the high temperature wind for avoiding energy loss and generating by vortex
Danger.Meanwhile by the way of compared to the outer core 50 using new old cable of script twisting into a bundle, contact area is effectively increased,
It is not easy to generate heat, further reduced high temperature risk, improve reliability.
Further, prepsetting gap is at least more than 2 millimeters.Certainly, prepsetting gap can be true according to power-on voltage in cable
Fixed, the too small vortex that still will lead to conducting connecting part 16 of prepsetting gap is formed.Specifically, the vertical coaxial electrical of conducting connecting part 16
The cross sectional shape of the longitudinally of cable is major arc shape.Wherein, the longitudinally of coaxial cable is up and down direction shown in FIG. 1.
In some embodiments, the outer diameter of conducting connecting part 16 is external exhausted less than in the first cable 20 (or second cable 30)
The radial dimension of edge layer, to ensure outer core 50 after being coated on the outside of conducting connecting part 16, that is, outer core 50 is coated on conduction
Behind the side of the first safeguard structure 14, the bodily form will not change too big connector 16.
In some embodiments, overlap-connected components further include locking member 11, and locking member 11 is located at conducting connecting part 16 and second
Between safeguard structure 18, and it is located at and is coated between the outer core 50 of conducting connecting part 16 and the second safeguard structure 18, locking member 11
It is set around the outside of conducting connecting part 16 along 12 circumferential direction of aluminium hydraulic pressed connecting pipe, for respectively by the outer of the first cable 20 and the second cable 30
Core 50 lock onto conducting connecting part 16.
Specifically, locking member 11 is locking copper wire.After outer core 50 is coated on conducting connecting part 16, locking copper wire is used
It is wrapped in the outside of outer core 50, outer core 50 is locked to the first side and second side of conducting connecting part 16.Due to cutting for copper wire
Face area is smaller, therefore the vortex generated is smaller, and caused energy loss is also very small.
In some embodiments, overlap-connected components further include fixing layer 13, and fixing layer 13 is located at conducting connecting part 16 and second
Between safeguard structure 18, and it is arranged along the circumferential direction of aluminium hydraulic pressed connecting pipe 12, for locking member 11, conducting connecting part 16 and first is electric
Cable 20 and the outer core 50 of the second cable 30 are fixed together, so that the outer core 50 of the first cable 20 and the second cable 30 is opposite
Conducting connecting part 16 is fixed.Further, fixing layer 13 is lead layer, the cutting along the longitudinally perpendicular to coaxial cable of lead layer
Face shape is similarly major arc shape, to avoid vortex is formed.Specifically, outer core 50 is locked at conducting connecting part 16 in locking copper wire
After above, by carrying out lead welding on the outside of conducting connecting part 16 to form lead layer, and copper wire, outer core 50 and conduction will be locked even
Fitting 16 is fixed together.
In some embodiments, conducting connecting part 16 along the longitudinally of coaxial cable length than aluminium hydraulic pressed connecting pipe 12 along coaxial
The length of the longitudinally of cable is small.Conducting connecting part 16 is the outer core 50 for connecting the first cable 20 and the second cable 30,
And outer core 50 is to be fixed on conducting connecting part 16 by locking member 11 and fixing layer 13, therefore only need to overlap in outer core 50
On conducting connecting part, conducting connecting part 16 is not necessarily to too long along the length of the longitudinally of coaxial cable.
Further, conducting connecting part 16 has the lengthwise along coaxial cable away from a side surface of the first safeguard structure 14
The outer core 50 of the first area and second area that direction is oppositely arranged, the first cable 20 is coated on the firstth area of conducting connecting part 16
The outer core 50 in domain, the second cable 30 is coated on the second area of conducting connecting part 16.Certainly, first area and second area both may be used
To be region of the surface along the edge of the longitudinally of coaxial cable, and first area is not spaced apart with second area;
First area and second area are also possible to respectively account for the half on the surface, i.e., without interval between first area and second area.
And it is understood that conducting connecting part 16 can not aluminium hydraulic pressed connecting pipe 12 crimping after be packed into, can only be in inner core
Before 40 crimping, the inner core 40 and internal insulating layer of the first cable 20 or the second cable 30 are inserted in conducting connecting part 16, so
The crimping of inner core 40 is carried out afterwards.Radial dimension due to 16 outer diameter of conducting connecting part less than external insulation, 40 sets of inner core
After entering conducting connecting part 16, conducting connecting part 16 can only be between the first cable 20 and the external insulation of the second cable 30
Movement, if conducting connecting part 16 is too long, possible 16 one end of conducting connecting part is connected to the first cable 20 (or the second cable
30) external insulation, the other end can extend to the wrapped region of the first protective layer, influence the formation of the first protective layer.
Further, conducting connecting part 16 is at least aluminium hydraulic pressed connecting pipe 12 along coaxial electrical along the length of the longitudinally of coaxial cable
The half of the length of the longitudinally of cable.Certainly, the length of conducting connecting part 16 can not be too short, and outer core 50 is made if too short
The length for being connected to 16 outside of conducting connecting part is inadequate, and the connection that may cause outer core 50 and conducting connecting part 16 loosens.Specifically
Ground, conducting connecting part 16 along the longitudinally of coaxial cable middle position and aluminium hydraulic pressed connecting pipe 12 along coaxial cable longitudinally
Middle position is overlapped, so that the both ends of conducting connecting part 16 are identical at a distance from the corresponding both ends of aluminium hydraulic pressed connecting pipe 12.
In some embodiments, the second safeguard structure 18 from the inside to the outside successively include insulating layer, waterproof layer and plastic layer,
To ensure aluminium hydraulic pressed connecting pipe 12 and exposed inner core 40 and extraneous isolation completely, insulation was both realized, external environment pair is also prevented
The influence of inner core 40.Specifically, insulating layer is insulating tape, waterproof layer is adhesive waterproof tape, and plastic layer is PVC tape, and is insulated
Adhesive tape laying is laid with always to the external insulation of the second cable 30 from the external insulation of the first cable 20, and other layers
Adhesive tape test successively covers insulating tape.It is understood that the second safeguard structure 18 is similar to the first safeguard structure 14, and
It is to be wound by adhesive tape, therefore it is also identical that it, which overlaps wrapped mode, therefore do not repeating.
Certainly, the first safeguard structure 14 and the second safeguard structure 18 in above-described embodiment, effect are not merely
Protection, but also have the function of connecting, the both ends of the first safeguard structure 14 extend to the first cable 20 and the second cable 30
Internal insulating layer, the both ends of the second safeguard structure 18 then extend to the external insulation of the first cable 20 and the second cable 30,
Also it can guarantee the stability of connection while playing protective action.
Please refer to Fig. 3, based on the above-mentioned overlap-connected components for coaxial cable, the invention further relates to one kind for same
The docking method of shaft cable, comprising the following steps:
First cable 20 or the second cable 30 are arranged in conducting connecting part 16, and the first cable 20 or the second electricity by S110
One end of cable 30 is stretched out from conducting connecting part 16.
In above-described embodiment it is stated that, in order to avoid inner core 40 crimping after conducting connecting part 16 can not be packed into, can only
