Embodiment
Below in conjunction with accompanying drawing, the anti-down electric supply installation of the utility model cable is further described:
Embodiment 1:
As depicted in figs. 1 and 2, the anti-down electric supply installation of the utility model cable, comprise the copper pipe 1 be coated on the Naked line position of cable 6, single-coated foam and insulating protection shell 3, the two ends of copper pipe 1 to its outer end cable insulation jacket 7 between be provided with gap, the cable insulation jacket 7 of single-coated foam from the two ends of copper pipe 1 respectively to its outer end is wound around, cover the position near cable insulation jacket 7 of copper pipe 1 simultaneously, the close position of copper pipe 1 of cable insulation jacket 7 and the gap between copper pipe 1 and cable insulation jacket 7, the elastic rubber belt 2 for making both be tightly connected is provided with between cable insulation jacket 7 and insulating protection shell 3, copper pipe is opposite structure, comprises half copper pipe of two involutory connections, insulating protection shell 3 is opposite insulating protection shell, comprises point shell 301 of at least two involutory connections, is provided with sealing joint strip 5, the involutory rear formation both ends open of insulating protection shell 3, the cable passing cavity of side-closed between adjacent point of shell 301.During use, can namely ensure to facilitate anti-down confession electric treatment, the effect of waterproof can be played again to the Naked line position of inside, copper pipe 1 covers Naked line position, when can ensure to need anti-down power supply to need ground connection, can conduct electricity, can coordinate with single-coated foam again simultaneously and waterproof is carried out to Naked line, and while the fail safe of its outer insulating protection housing secures arranged, waterproof can be carried out further to the copper pipe of inside, Naked line position.The anti-down electric supply installation of the utility model cable, structure is simple, easy to use, only need by two and half copper pipes to being combined on Naked line position, wrap up single-coated foam again, the parcel of single-coated foam extends outwardly on its outer cable insulation jacket from copper pipe, then arranges elastic rubber belt, involutory insulating protection shell, waterproof can be carried out to Naked line position, fail safe is good, avoids the wasting of resources, and elastic rubber belt is arranged, ensure that the sealing between insulating protection shell and cable insulation jacket, make waterproof effect better.
Labyrinth seal is adopted between preferred insulating protection shell 3 and elastic rubber belt 2, this kind of structure improves the sealing between insulating protection shell and cable insulation jacket, make waterproof effect better, simultaneously anti-skidding to carrying out between insulating protection shell 3 and elastic rubber belt 2, during use, involutory insulating protection shell 3, can enter into Naked line position from the two ends of insulating protection shell 3 by anti-sealing, improves waterproof effect.Wherein labyrinth seal can adopt following structure: insulating protection shell 3 inner surface be provided with labyrinth type projection or groove with elastic rubber belt 2 corresponding position, stop water elastic rubber belt 2 being provided with accordingly labyrinth type groove or projection this kind of labyrinth seal formation coordinated with it effectively can improve water resistance, also effectively can prevent the slip of insulating protection shell; The height of preferred labyrinth type groove is slightly larger than the height of labyrinth type projection, highly all refer to the size in insulating protection shell 3 radial direction, the benefit of this kind of structure is that groove can hold aqueous vapor, even if humid environment, moisture does not enter Naked line position yet, improves water resistance; The height of preferred labyrinth type groove is compared with the large 0.2-2mm of the height of labyrinth type projection, and the restriction of this difference in height, can ensure that insulating protection shell 3 well can be fitted with elastic rubber belt 2, can improve waterproof effect anti-skidding or further again simultaneously.
Preferred elastomeric adhesive tape 2 covers single-coated foam completely, and what single-coated foam directly covered is Naked line position, exists and has a common boundary, the covering completely of elastic rubber belt 2 with copper pipe 1 and cable insulation jacket, and what formed Naked line position is multi-sealed, can improve water resistance further.
Hinged between preferably adjacent point shell 301, fastening by locking device 4 between two points of shells 301 of involutory side.Be convenient to folding insulating protection shell 3; Copper pipe 1 and the insulating protection shell 3 of both ends open, side-closed all adopt butted structure, and the convenient cable infinitely extending arranges the anti-down electric supply installation of cable.
The side that wherein two and half copper pipes are adjacent is hinged, and involutory side is screwed, or the adjacent side of two and half copper pipes and involutory side are all screwed.Copper pipe can not be dismantled, adopt and be screwed after being usually arranged on Naked line position, ensures its reliability connected, and two and half copper pipes are hinged, and be convenient installation, but hinged structure is also comparatively complicated, both sides all use the hinged structure of screw more easily to produce in batches.Two and half shells involutory, also can be set to the hermetically-sealed construction being with groove to match with projection, can seal by available waterproof gasket cement.
Finally should illustrate; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection range; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
