Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, Fig. 2 and Fig. 3, a kind of split type conductor splice device, comprisepivoted housing body 1 and therotor body 2 that continues that continues, continuebody 1 of described pivoted housing is cylindrical structural, its two ends are respectively equipped with the end of a thread trepanning 1-1 and rotor grooving 1-2, rotor grooving 1-2 comprises spacing end difference 1-2-1 and Plug Division 1-2-2, the describedrotor body 2 that continues comprises the spacing switch block 2-1 that matches with the spacing end difference 1-2-1 of rotor grooving 1-2, spacing switch block 2-1 is connected with the end of a thread sleeve 2-3 by connecting rod 2-2, and the connecting portion of the end of a thread sleeve 2-3 and connecting rod 2-2 is that taper shape seamlessly transits structure.Above-mentioned spacing switch block 2-1, connecting rod 2-2 and the end of a thread sleeve 2-3 are integral structure, and spacing switch block 2-1 is the cylindrical structural with circular chamfering, and the Plug Division 1-2-2 of rotor grooving 1-2 and spacing end difference 1-2-1 are provided with the corresponding circular chamfering with spacing switch block 2-1.

When the utility model uses, earlier the end of a thread of two sectionsconductor thread cores 3 that need continued access mode by the hydraulic pressure extruding is separately fixed at pivoted housing the end of a thread trepanning 1-1 ofbody 1 and the rotor 2-3 in the end of a thread sleeve ofbody 2 that continues that continues, the continue spacing switch block 2-1 ofbody 2 of rotor is placed in the rotor grooving 1-2 by Plug Division 1-2-2, because in the insulating exruded operation ofconductor thread core 3, there is bigger axial tension between theconductor thread core 3, the spacing end difference 1-2-1 of rotor grooving 1-2 can closely cooperate with spacing switch block 2-1, thereby makecontinue body 1 and rotor of pivoted housing continue and be merely able to carry out relatively rotating of axial direction between thebody 2, and discharge the axial torsion thatconductor thread core 3 is produced in insulating exruded operation with this, prevent that the stranded conductor thread core of finishing 3 back twists are loose, can enhance productivity.Cylindrical spacing switch block 2-1 has circular chamfering, and the spacing end difference 1-2-1 of rotor grooving 1-2 and Plug Division 1-2-2 be equipped with the circular chamfering corresponding with spacing switch block 2-1, helps the rotation of spacing switch block 2-1 in rotor grooving 1-2.
