Abstract
The utility model relates to a prefabricated branch cable, mainly solving the problems of bad firmness of the connection of the cable insulating barrier and the die housing and bad sealing property of the exiting prefabricated branch cable. The utility model is characterized in that a main cable (2) in a die housing (1), an insulating barrier (4) of a branch cable (3) and a sheath (6) are all coated with a hot melt adhesive layer (5). The prefabricated branch cable has the characters of good firmness of the connection of the cable insulating barrier and the die housing, good sealing property.
Description
Technical field:
The utility model relates to transmission of electricity and uses single-core cable, belongs to a kind of prefabricated branch cable.
Background technology:
Chinese patent 98241548.6 discloses a kind of prefabricated branch cable, wherein in making association of branch technical process, injection moulding PVC die sleeve is a critical process, require the insulating barrier of PVC die sleeve and leader cable, branch cable to combine securely, good resistance effect is arranged, should guarantee that under 3.5KV voltage immersion 1 hour is not breakdown, soaking insulation resistance should be not less than 200 megaohms; Because die sleeve is the PVC material, and the insulating barrier of cable is PVC, crosslinked polyethylene or other material, above-mentioned material does not reach melt temperature when injection moulding PVC die sleeve like this, wherein some material is again nonpolar, therefore to combine fastness poor for cable insulation and die sleeve, processing technology is required height, poor sealing performance.
The utility model content:
Fastness is poor, the deficiency of poor sealing performance for the cable insulation that overcomes existing prefabricated branch cable combines with die sleeve, the utility model provides a kind of prefabricated branch cable, and this prefabricated branch cable has cable insulation and combines with die sleeve that fastness is good, the characteristics of good seal performance.
The technical solution of the utility model is: this prefabricated branch cable comprises die sleeve, leader cable and branch cable, and the leader cable in the die sleeve and the insulating barrier and the jacket outer surface of branch cable all scribble hot melt adhesive layer.
The utlity model has following beneficial effect: owing to take the leader cable in the die sleeve in the such scheme and the insulating barrier and the jacket outer surface of branch cable to scribble hot melt adhesive layer, when injection moulding PVC die sleeve, hot melt adhesive layer can bond together the insulating barrier of leader cable and branch cable and sheath and die sleeve closely, good in conjunction with fastness, sealing is reliable simultaneously, guaranteed that immersion voltage test and soaking insulation resistance are up to standard, reduced requirement processing technology.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-die sleeve among the figure, 2-leader cable, 3-branch cable, 4-insulating barrier, 5-hot melt adhesive layer, 6-sheath.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this prefabricated branch cable comprises die sleeve 1, leader cable 2 and branch cable 3, leader cable 2 links to each other with branch cable 3 and outer intrinsic die sleeve 1, leader cable 2 in the die sleeve 1 all scribbles hot melt adhesive layer 5 with the insulating barrier 4 and sheath 6 outer surfaces of branch cable 3, when injection moulding PVC die sleeve 1, hot melt adhesive layer 5 can bond together insulating barrier 4 and the sheath 6 of leader cable 2 with branch cable 3 with die sleeve 1 closely, good in conjunction with fastness, sealing is reliable simultaneously, guaranteed that immersion voltage test and soaking insulation resistance are up to standard, reduced requirement processing technology.
Claims (1)
