The bar-shaped trough and the mounting hole of bearing pin 25 matched somebody with somebody.Movable mold 22 is located at the top of stent 21, and its longitudinally outboard has to be led with linear pattern
The chute that rail 23 matches, its downside are the circular arc of indent.Adjusting screw rod 24 uses T-shaped screw rod, and its lower end passes through stent 21
Upper end after connected as one with the upper end of movable mold 22, there is corresponding screwed hole the upper end of stent 21.Adjusting screw rod 24
Upper end is connected with regulation handle 26.
As shown in Figure 4, Figure 5, crimping tool includes the hydraulic tongs and homemade crimp 3 of outsourcing, and crimp 3 includes
The semi-circular tube 31 of two heavy walls.The interlude of the axial centre line three-way hole of semi-circular tube 31 is circular hole section 311, the two of the circular hole section
Regular hexagon hole section 312 is terminated, regular hexagon hole section 12 connects outward end circular hole section 313 again.Regular hexagon hole section 312 is as crimping
Section makes this mould have two crimp segments.
The length direction middle position of the outer wall of semi-circular tube 31 has annular groove 314, and the setting of annular groove 314 to adopt
The effect crimped twice with hydraulic tongs is more preferable.
The length of circular hole section 311 is more than the length of two outward end circular sections 313 among the axial central through hole of semi-circular tube 31, with
This mould is crimped closer to the bar portion if T connector portion is open tube, improve crimping effect.
Make mains supply line using above-mentioned T-shaped shunting aluminium hydraulic pressed connecting pipe and its pressure circle, crimping tool the invention also discloses one kind
The method of parallel shunt, comprises the following steps：
（1）Shunting cable is crimped with T-shaped shunting aluminium hydraulic pressed connecting pipe and is integrated；
（2）The dielectric glass layer that main service cable is corresponded at diverter branch link position is spilt into cable under powering-off state
Core；
（3）T-shaped shunting is crimped into the c-type pipe sleeve of tube head in step（2）In on exposed cable core；
（4）The exposed cable core of the head c-type Guan Yuzhu service cables of T-shaped shunting aluminium hydraulic pressed connecting pipe is crimped using crimping tool
It is formed as one diverter branch；
（5）Insulation processing is done to the cable core and T-shaped shunting aluminium hydraulic pressed connecting pipe of main service cable and shunting cable exposure；
（6）The other end for shunting cable is connected by banjo fixing butt jointing with the wall bushing of feeder pillar or ring main unit, made
Feeder pillar or ring main unit access power supply grid with parallel form.
Step（4）In crimping tool can also be the supporting corresponding crimp 3 of hydraulic pressure Press Plier, such as Fig. 4, Fig. 5 institute
Show, crimp 3 includes the semi-circular tube 31 of two heavy walls, and the interlude of the axial centre line three-way hole of semi-circular tube 31 is circular hole section
311, two termination regular hexagon hole sections 312 of the circular hole section, regular hexagon hole section 312 connects outward end circular hole section 313 again.Positive six
Side shape hole section 312 makes this mould have two crimp segments as crimp segment.
The length direction middle position of the outer wall of semi-circular tube 1 has annular groove 14, and the setting of annular groove 14 to use
The effect that hydraulic tool is crimped twice is more preferable.
The length of circular hole section 11 is more than the length of two outward end circular sections 13 among the axial central through hole of semi-circular tube 1, so that
This mould can be crimped closer to the bar portion if T connector portion is open tube, improve crimping effect.
As shown in fig. 6, T-shaped shunting aluminium hydraulic pressed connecting pipe is crimped on main service cable by supporting self-control crimp of outsourcing hydraulic tongs
Cable core on when, have two crimp segments respectively at the head both ends of T-shaped shunting aluminium hydraulic pressed connecting pipe, and crimp segment is from T-shaped shunting crimping
The bar portion of pipe is close, and crimping effect is good.Second of crimping only needs movable hydraulic Press Plier during crimping operation, and crimp is without weight
Newly it is socketed and installs with cable core, it is simple to operate and efficient.
The T-shaped shunting aluminium hydraulic pressed connecting pipe of the present invention is before use, will first shunt the bar of the cable and T-shaped shunting aluminium hydraulic pressed connecting pipe of cable socket
Portion's crimping is integrated, by the insulation displacement at the T-shaped shunting aluminium hydraulic pressed connecting pipe link position of main service cable；Then under powering-off state
The cable core for having peeled off insulating barrier is passed through from the head c-type pipe of T-shaped shunting aluminium hydraulic pressed connecting pipe, crimping tool stent will be made by oneself
Lower end is held on the downside of the head c-type pipe of T-shaped shunting aluminium hydraulic pressed connecting pipe, drives the movable mold edge of crimping tool straight finally by regulation screw mandrel
Linear guide rail move down down pressed to c-type pipe top make its be rounded by cable core parcel be integrated, finally to it is T-shaped shunting press
Adapter and exposed cable core carry out insulation processing.The T-shaped conductive shunting of shunting aluminium hydraulic pressed connecting pipe can be passed through after energization.
Crimping tool can also use outsourcing hydraulic pressure Press Plier and make the composition structure that crimp coordinates, homemade crimping by oneself
The interlude of its semi-circular tube axial central through hole is designed as the larger circular hole in aperture by mould, and it is smaller that this section of circular hole two terminates aperture
Regular polygon hole section, the larger circular hole portion in the outer end Zai Jie apertures of regular polygon hole section, crimping tool passes through regular polygon section
Open tube is pressed as crimp segment and justified, a mould there are two crimp segments, and only crimping tool need to be moved i.e. after having crimped once
It can again crimp, the purpose of crimping efficiency is improved while realizing and improve crimping effect.In order that the effect crimped twice is more preferable,
In the length direction middle position of semicircle pipe outer wall, annular groove is set.In order that this mould can be opening closer to such as head
The bar portion of the T-shaped shunting aluminium hydraulic pressed connecting pipe of pipe is crimped, and improves crimping effect, by circular hole section among semi-circular tube axial central through hole
Length be more than both ends circle hole section length.
T-shaped shunting aluminium hydraulic pressed connecting pipe directly is crimped to be integrated and shunted with the cable core of main service cable, without by main power supply
The cable core of cable turns off, and maintains the mechanical strength and electric conductivity of cable core.
The crimping tool that T-shaped shunting aluminium hydraulic pressed connecting pipe wraps up main service cable cable core is the cooperation of stent and movable mold, living
The movement of dynamic model has guide rail guiding, and crimping process stabilization, crimping effect are good.Whole crimping process, mechanically realizes, grasps
Make simple.
Use of the T-shaped shunting aluminium hydraulic pressed connecting pipe on mains supply line, makes each diverter branch access main supply lines with parallel form
Road, realize that the feeder pillar on each diverter branch or ring main unit work independently and be independent of each other, improve power supply reliability and security
Purpose, overcome prior art diverter branch top set's case or ring main unit be series on mains supply line shunt it is existing before
State defect.
