Fig. 2 is the flow chart of the preparation method of another cable branch joint provided in an embodiment of the present invention, with reference to
The preparation method that 3~13 couples of Fig. 2 of accompanying drawing are provided is described in detail：
S211：Wire stripping is carried out to the end of leader cable to be connected and point cable.
Fig. 3 is the structural representation after a kind of leader cable wire stripping provided in an embodiment of the present invention, as shown in figure 3, in wire stripping
When, the length that the oversheath 15 of leader cable 10 is peeled off can be 0.5L+130mm, and wherein L is the copper in subsequent step for connecting
The length of pipe.The length that screen layer 14 is exposed to oversheath 15 can be 35~45mm, preferably 40mm.Wrapped 13 are exposed to screen
The length for covering layer 14 can be 15~25mm, preferably 20mm.Core dew 11 can be 0.5L+ for the length of insulating barrier 12
5mm。
Divide the structure of cable and leader cable essentially identical, the diameter for differing only in leader cable is more than the diameter of point cable.
By wire stripping, so that screen layer, wrapped, insulating barrier and the core of leader cable and point cable are exposed to oversheath.In the present embodiment
In, a point cable has 2.
The length for dividing the oversheath of cable to peel off can be 0.5L+145mm.The length that screen layer is exposed to oversheath can be with
For 35~45mm, preferably 40mm.The wrapped length for being exposed to screen layer can be 15~25mm, preferably 20mm.Core reveals
Length for insulating barrier can be 0.5L+5mm.
S212：Internal layer heat-shrink tube, copper braiding net sleeve, outer layer heat-shrink tube are arranged on leader cable.
Wherein, the diameter of outer layer heat-shrink tube is maximum, and secondly, internal layer heat-shrink tube is minimum for copper braiding net sleeve, so can be in order to
In subsequent step, copper braiding net sleeve is enclosed on internal layer heat-shrink tube, by outer layer shrinkable sleeve on copper braiding net sleeve.
Alternatively, the length of outer layer heat-shrink tube can be L+400mm, and the length of internal layer heat-shrink tube can be L+220mm.
The length of copper braiding net sleeve should at least be more than the length of internal layer heat-shrink tube, because copper braiding net sleeve can make
During cut, in order to ensure copper mesh grid is cased with enough length, set copper braiding net sleeve when, copper can be woven
The length of net is set to L+500mm.
S213：Hoop pricks the core of point cable.
Wherein, the termination alignment of the core of many point cables.
By the way that the core hoop of two pieces points of cables is tied up come can be in order to the core of point cable is inserted into copper in subsequent step
Guan Zhong.The core of point cable can be specifically pricked using copper cash hoop.
S214：The core of the core of leader cable and point cable is inserted to the two ends of copper pipe respectively.
Fig. 4 is a kind of copper pipe connection diagram provided in an embodiment of the present invention.As shown in figure 4, the core 11 of leader cable 10
The length for inserting copper pipe 31 and the length for the insertion copper pipe 31 of core 21 for dividing cable 20 are the half of the length of copper pipe 31, so may be used
So that copper pipe 31 and leader cable 10 and a point cable 20 have larger contact area, be conducive to reducing the resistance of branch joint, from
And the heating of branch joint is reduced, further increase security.
Preferably, the cross-sectional area of the through hole of copper pipe 31 can be the cross-sectional area sum of the core 21 of 2 pieces points of cables 20
1.2~1.5 times, so can be easy to core 21 insert copper pipe 31 on the premise of, make between the inwall and core of copper pipe 31
Spacing it is smaller, if the cross-sectional area of the through hole of copper pipe 31 is excessive, gap can be caused excessive, connecing between core and copper pipe 31
Contacting surface product reduces., can also be in copper pipe after the core 21 of the core 11 of leader cable 10 and point cable 20 is inserted into copper pipe 31
Filling tin silk in 31, to reduce the gap between core and copper pipe 31.
It should be noted that when a point cable 20 has 3, then the cross-sectional area of the through hole of copper pipe 31 is 3 pieces points of cables 20
1.2~1.5 times of cross-sectional area sum of core 21, i.e. the cross-sectional area of the through hole of copper pipe 31 is the line of all points of cables 20
1.2~1.5 times of the cross-sectional area sum of core 21.
Alternatively, the length of copper pipe 31 can be 90~110mm, if copper pipe 31 is too short, core contact with copper pipe 31
Area is smaller, and bonding strength is relatively low, if copper pipe 31 is oversize, branch joint can be caused too big, it has not been convenient to the bending of cable.
S215：Copper pipe is crimped from the middle part of copper pipe to two ends interval.
Copper pipe 31 can be crimped by Press Plier when realizing, copper pipe 31 is extruded by Press Plier, pressure is formed on copper pipe 31
Hole, makes copper pipe 31 clamp core, because copper pipe 31 can be deformed upon during crimping, and copper pipe 31, which is squeezed, to be prolonged to two ends
Certain length is stretched, therefore is crimped from the middle to both ends, the length that copper pipe 31 can be made to extend to leader cable 10 and point cable 20
It is equal.The length that the length and the core 21 of point cable 20 exposed due to the core 11 of leader cable 10 are exposed is 0.5L+5mm,
The length of the insertion copper pipe 31 of core 21 of the core 11 of leader cable 10 and point cable 20 is the half of the length of copper pipe 31, therefore
Before crimping, the core 21 of the core 11 of leader cable 10 and point cable 20 has 5mm to be exposed at outside copper pipe 31, so as to meet copper
The deformation of pipe 31.
Specifically, at interval of 10mm a load mould can be squeezed out on copper pipe 31, to improve crimp strength.Forming pressure
During hole, copper pipe is clamped by Press Plier and kept for more than 10 seconds, so that it is guaranteed that the copper pipe 31 at crimping position is plastically deformed, will
Core is clamped.
S216：Polishing copper pipe.
By polishing can remove the burr on the surface of copper pipe 31, it is ensured that the surface of copper pipe 31 it is smooth, it is to avoid on copper pipe 31
Burr scratches insulating self-adhesive band for being wound in subsequent step etc..
After polishing is finished, the surface of alcohol wipe copper pipe 31, to remove the spot on the surface of copper pipe 31, side can also be used
Just the winding of insulating self-adhesive band.
