Abstract
The present invention relates to a cold-shrunk cable accessory expanded by new process. Before the cold-shrunk cable accessory is expanded, a flexible bag can be placed on its inner wall in advance, after the expansion die and cable accessory are separated by means of said flexible bag, said flexible bag can prevent the expansion die from damaging said cable accessory, after the cold-shrunk cable accessory is expanded, a supporting is placed on the inner wall of flexible bag. When it is used, the supporting tube is pulled while the flexible bag is drawn, so that the supporting tube and flexible bag can be easily removed.
Description
Technical field the present invention relates to a kind of new method cold-shrunk cable accessory expanded---comprise that cold shrink tube and other need the product scope through predilation.
Background technology is present, the related electric cable accessories in above-mentioned field generally all adopts mechanical gentle companding to open method, used stay pipe has two big classes: the first kind, be to be welded into plastic tube or inside of plastic tubes is cut into spiral goove, have mentioned as Chinese patent ZL002504.3 and ZL01254899.5 with the spiral plastic strip; Second class is to be coated with one deck slip film in ganoid plastic tube appearance, and CN1255252A describes as French Patent (FRP).In fact find that these two kinds of methods all have a common shortcoming---dilatation mold directly contacts with electric cable accessories, makes cold shrinking power cable adjunct damage frequency height, and have potential safety hazard in the product use.
The present invention is just in order to address the aforementioned drawbacks.
Summary of the invention the objective of the invention is to make cold shrinking power cable adjunct by a kind of new expansion method: before the cold shrinking power cable adjunct expansion, inner wall in advance is placed flexible pouch; Flexible pouch can select fiber textile, nonwoven fabrics and polymeric membrane any one and the group (answering) close; After flexible pouch separates dilatation mold and electric cable accessories, avoided the dilatation mold electric cable accessories of wearing; Stay pipe is placed again at the flexible pouch inwall in the expansion back.
Stay pipe of the present invention is by hot melt self-adhering method and resin solidification manufactured: the hot melt self-adhering method is that the plastics by linear twine, through being heated to the self-adhesive of plastics lines becomes after the semi-molten state the circle or the helix of square; The resin solidification method is by plastics lines or metal wire, twines the circular or square spiral type tubulose that is bonded to after the cooling again (or heating, radiation curing) through soaking PUR (or thermosetting resin) back.Stay pipe with these two kinds of methods manufacturings, during use if any end at its two ends push aside one section the lead-in wire and continue to draw back, stay pipe can be reduced into the same linear of spring, the lines limit of limit pulling stay pipe drops flexible pouch, stay pipe and flexible pouch can withdraw from easily, have work efficiency height, characteristics that cost is low.
Stay pipe of the present invention can be to be made by tongue and groove interlock method or high-frequency electrical, magnetic oscillation method.
Description of drawings Fig. 1 is one of new expansion method step of the present invention, the generalized section of cold shrinking power cable adjunct before expansion.Fig. 2 is two of a new expansion method step of the present invention, and cold shrinking power cable adjunct was placed the generalized section of flexible pouch in advance before expansion.Fig. 3 is three of a new expansion method step of the present invention, the generalized section of cold shrinking power cable adjunct after expansion.Fig. 4 is four of a new expansion method step of the present invention, cold shrinking power cable adjunct is placed stay pipe again after expansion generalized section.Fig. 5 be with make from molten mull technique stay pipe schematic diagram; Fig. 6 be with resin method make stay pipe schematic diagram.
The structure of each label representative or function are as follows among the figure:
1---cold shrinking power cable adjunct; 2---flexible pouch; 3---stay pipe; 4---(stay pipe dismounting) lead-in wire; 5---the plastics lines; 6---plastics or metal wire; 7---PUR or thermosetting resin liquid cell; 8---plug.
Embodiment
Narrate the implementation step that new expansion method of the present invention is made cold shrinking power cable adjunct by Fig. 1 to Fig. 6, and Fig. 1 to Fig. 4 all simple the appearance of cold shrinking power cable adjunct.
Cold shrinking power cable adjunct 1 shown in Figure 1 is that cold shrink tube and other need all can select for use liquid or solid silicon rubber or ethylene propylene diene rubber to make through any one of predilation product, and its external form can adopt the molded curing moulding according to the design needs of cold shrinking power cable adjunct 1.
Placed flexible pouch 2 by mode shown in Figure 2 in advance before cold shrinking power cable adjunct 1 expansion, flexible pouch can select any one and group (answering) thereof of fiber textile, nonwoven fabrics and polymeric membrane to close.
Cold shrinking power cable adjunct 1 is expanded to the technology caliber that needs by mode shown in Figure 3 again.Omitted the schematic diagram of dilatation mold among the figure.
Just become product after then placing stay pipe 3, omitted the process of removing dilatation mold among the figure by the requirement of Fig. 4.Because after flexible pouch 2 separates dilatation mold and electric cable accessories 1, avoided the dilatation mold electric cable accessories of wearing, guaranteed the rate of finished products and the reliability of product.As long as will push aside during use one section lead-in wire 4 draws back, stay pipe 3 can be reduced into the same lines of spring 5, pulling stay pipe 4 limits that go between in limit drop flexible pouch 2, and stay pipe 3 and flexible pouch 2 can withdraw from easily, and be easy for installation.
According to the requirement of Fig. 5 the HDPE lines 5 of circle are closely twined and to have mercy on metal mandrel 8, pinion two of HDPE lines 5, insulation is 10-120 minute in 140 ℃-220 ℃ temperature, take out cool to room temperature and pull out metal mandrel 8, the spiral HDPE pipe of moulding is cut into the length that needs, pushing one section lead-in wire aside at any end at its two ends promptly becomes stay pipe 3 among Fig. 4 again.
According to the requirement of Fig. 6 with plastics lines or metal wire 5, after soaking, PUR that elder generation's process is 80-220 ℃ or the thermosetting resin liquid cell under the normal temperature 7 be wound into again on the plug 8, circular or the square spiral type tubulose that after supercooling (or being heating and curing), is bonded to, the helix tube of moulding is cut into the length that needs, also pushing one section lead-in wire aside at any end at its two ends promptly becomes stay pipe 3 among Fig. 4 again.
