As shown in Figure 4, Figure 5, crimping tool comprises hydraulic tongs and the homemade crimp 3 of outsourcing, and crimp 3 comprises the semi-circular tube 31 of two heavy walls.The interlude of semi-circular tube 31 axial centre line three-way hole is circular port section 311, and two termination regular hexagon hole sections 312 of this circular port section, regular hexagon hole section 12 connects outward end circular hole section 313 again.Regular hexagon hole section 312 makes this mould have two crimp segment as crimp segment.
The length direction middle position of semi-circular tube 31 outer wall has annular groove 314, and being arranged so that of annular groove 314 adopts hydraulic tongs to carry out the better effects if of twice crimping.
In the middle of semi-circular tube 31 axial central through hole, the length of circular port section 311 is greater than the length of two outward end circular sections 313, to make this mould can crimp closer to the bar portion that such as T connector portion is open tube, improves crimping effect.
The invention also discloses and a kind ofly utilize above-mentioned T-shaped shunting aluminium hydraulic pressed connecting pipe and pressure circle thereof, crimping tool makes the method for mains supply line parallel shunt, comprise the following steps:
(1) shunting cable is crimped with T-shaped shunting aluminium hydraulic pressed connecting pipe be integrated;
(2) under powering-off state, the dielectric glass layer at corresponding for main service cable diverter branch link position place is spilt cable core;
(3) by cable core exposed in step (2) for the C type pipe box of T-shaped shunting aluminium hydraulic pressed connecting pipe head;
(4) adopt crimping tool that cable core exposed for the head C type Guan Yuzhu service cable of T-shaped shunting aluminium hydraulic pressed connecting pipe crimping is formed as one diverter branch;
(5) insulation processing is done to main service cable and the cable core and T-shaped shunting aluminium hydraulic pressed connecting pipe shunting cable exposure;
(6) other end of shunting cable is connected by the wall bushing of banjo fixing butt jointing with feeder pillar or ring main unit, makes feeder pillar or ring main unit access power supply grid with parallel form.
Crimping tool in step (4) can also be the supporting corresponding crimp 3 of hydraulic pressure Press Plier, as shown in Figure 4, Figure 5, crimp 3 comprises the semi-circular tube 31 of two heavy walls, the interlude of semi-circular tube 31 axial centre line three-way hole is circular port section 311, two termination regular hexagon hole sections 312 of this circular port section, regular hexagon hole section 312 connects outward end circular hole section 313 again.Regular hexagon hole section 312 makes this mould have two crimp segment as crimp segment.
The length direction middle position of semi-circular tube 1 outer wall has annular groove 14, and being arranged so that of annular groove 14 adopts hydraulic tool to carry out the better effects if of twice crimping.
In the middle of semi-circular tube 1 axial central through hole, the length of circular port section 11 is greater than the length of two outward end circular sections 13, to make this mould can crimp closer to the bar portion that such as T connector portion is open tube, improves crimping effect.
As shown in Figure 6, when T-shaped shunting aluminium hydraulic pressed connecting pipe is crimped on the cable core of main service cable by supporting of outsourcing hydraulic tongs self-control crimp, have two crimp segment respectively at the head two ends of T-shaped shunting aluminium hydraulic pressed connecting pipe, and crimp segment from T-shaped shunting aluminium hydraulic pressed connecting pipe bar portion very close to, crimp effective.During crimping operation, second time crimping only needs movable hydraulic Press Plier, and crimp is installed without the need to again be socketed with cable core, simple to operation and efficiently.
Before T-shaped shunting aluminium hydraulic pressed connecting pipe of the present invention uses, first the cable of branch cable termination is crimped with the bar portion of T-shaped shunting aluminium hydraulic pressed connecting pipe and be integrated, by the insulation displacement at T-shaped for main service cable shunting aluminium hydraulic pressed connecting pipe link position place; Then under powering-off state, the cable core peeling off insulating barrier is passed from the head C type pipe of T-shaped shunting aluminium hydraulic pressed connecting pipe, the lower end of self-control crimping tool fixed die is held on the downside of the head C type pipe of T-shaped shunting aluminium hydraulic pressed connecting pipe, finally by regulate screw mandrel drive crimping tool movable mold linearly type guide rail move down to C type pipe top down exert pressure make its become circle by cable core parcel be integrated, finally insulation processing is carried out to T-shaped shunting aluminium hydraulic pressed connecting pipe and exposed cable core.Namely by the shunting of T-shaped shunting aluminium hydraulic pressed connecting pipe conduction after energising.
The composition structure that crimping tool also can adopt outsourcing hydraulic pressure Press Plier and self-control crimp to coordinate, the interlude of its semi-circular tube axial central through hole is designed to the larger circular hole in aperture by homemade crimp, the regular polygon hole section that this section of circular hole two termination aperture is less, the circular hole portion that the Zai Jie aperture, outer end of regular polygon hole section is larger, open tube is pressed circle by regular polygon section as crimp segment by crimping tool, a mould has two crimp segment, having crimped once only needs mobile crimping tool again to crimp, the object of crimping efficiency is improved while realizing improving crimping effect.In order to make the better effects if of twice crimping, annular groove is set in the length direction middle position of semi-circular tube outer wall.In order to make the bar portion that this mould can be the T-shaped shunting aluminium hydraulic pressed connecting pipe of open tube closer to such as head crimp, improve crimping effect, the length of circular port section in the middle of semi-circular tube axial central through hole is greater than the length of two ends circular port section.
T-shaped shunting aluminium hydraulic pressed connecting pipe directly crimps to be integrated with the cable core of main service cable and shunts, and without the need to being disconnected by the cable core of main service cable, maintains mechanical strength and the 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 fixed die and movable mold, and the movement of movable mold has guide rail to lead, crimping process stabilization, crimp effective.Whole crimping process, realizes mechanically, simple to operate.
The use of T-shaped shunting aluminium hydraulic pressed connecting pipe on mains supply line, each diverter branch is made to access mains supply line with parallel form, realize feeder pillar on each diverter branch or ring main unit to work alone and to be independent of each other, to improve the object of power supply reliability and fail safe, overcome prior art diverter branch top set's case or ring main unit is series at aforementioned drawback mains supply line being shunted existence.
