Background
Cable is a generic term for optical cables, electrical cables, and the like. Cables are used for many purposes, such as controlling installations, connecting equipment, transmitting power, and the like. When using the cable in the building construction field, there is the cable to drag in ground, has workman or construction equipment to cross the cable in addition, extrudees the cable, in case the compressive property of cable meets the end, has the cable fracture very probably, and causes the power transmission to break off, influences the problem of construction.
The current chinese utility model patent that patent number is 202120387709.7 discloses a withstand voltage wind-powered electricity generation special cable, and it sets up movable sleeve, backing sheet and flexure strip and carries out the reinforcing of crushing resistance, but, when its movable sleeve received the extrusion, backing sheet and the direct deformation of flexure strip were in order to withstand voltage, and it is great to have the clearance between the adjacent backing sheet, and the lower problem of withstand voltage nature when corresponding movable sleeve received the extrusion.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a better cable of whole compressive property to the not enough that exists among the above-mentioned background art.
In order to achieve the above object, the utility model relates to a resistance to compression cable has adopted following technical scheme:
the utility model provides a resistance to compression cable, includes the sinle silk, and sinle silk periphery side is provided with the internal insulation layer, the sinle silk is provided with the multiunit, and multiunit sinle silk periphery side is provided with the external insulation layer, is provided with fire-retardant filling layer between multiunit sinle silk and the external insulation layer, external insulation layer periphery layer has still set gradually waterproof layer, metal armor, the metal armor outside still is provided with the restrictive coating that is used for the resistance to compression, restrictive coating periphery side is provided with the fixed lug that a plurality of intervals were laid, the intraductal week side of restrictive coating is provided with the curved bulge that is laid of a plurality of intervals, and the bulge supports the metal armor, fixed lug and the bulge dislocation are laid.
The utility model relates to a further improvement part of resistance to compression cable lies in, and the restrictive coating is left and right sides end looks joint rubber materials component that encloses, controls and is provided with the locating part in the clearance between two bulges of both sides end looks joint department.
The utility model relates to a further improvement part of resistance to compression cable lies in, and the restrictive coating is provided with a plurality of sections, and core length direction arranges along the line lays.
The utility model relates to a further improvement part of resistance to compression cable lies in, is provided with slot and plug-in components around the restrictive coating respectively, and the plug-in components and the slot of adjacent restrictive coating are pegged graft mutually.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses set up the restrictive coating and guarantee the holistic crushing resistance of cable, fixed lug and bulge make the restrictive coating inside and outside all possess certain crushing resistance, simultaneously, the two is staggered mutually and is laid, also makes the restrictive coating whole can disperse the atress when the pressurized, guarantees withstand voltage stably. On the other hand, the restrictive coating installation is dismantled also comparatively conveniently, installs in the easy extruded position of receiving of cable, can realize key local protection and reach the purpose of material saving.
Drawings
Fig. 1 is a schematic cross-sectional structure of the present invention;
in the figure: 1 sinle silk, 2 fire-retardant filling layers, 3 outer insulating layers, 4 waterproof layers, 5 metal armor layers, 6 restrictive coatings, 61 fixed lugs, 62 bulges, 63 plug-in components, 7 locating parts.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
As shown in fig. 1, a resistance to compression cable, including sinle silk 1, sinle silk periphery side is provided with the inner insulation layer, the sinle silk is provided with the multiunit, and multiunit sinle silk periphery side is provided with outer insulation layer 3, is provided with fire-retardant filling layer 2 between multiunit sinle silk and the outer insulation layer, outer insulation layer periphery layer has still set gradually waterproof layer 4, metal armor 5. The above is the conventional cable structure of the prior art. Further, the metal armor layer outside still is provided with restrictive coating 6 that is used for the resistance to compression, and restrictive coating periphery side is provided with the fixed lug 61 that a plurality of intervals were laid, the week side is provided with the curved bulge 62 that is that a plurality of intervals were laid in the restrictive coating, and the bulge supports the metal armor layer, and fixed lug and bulge dislocation are laid. The high-strength pressure resistance can be realized by the inner layer and the outer layer of the sheath layer, and meanwhile, the fixing lug and the protruding part are arranged in a staggered mode, so that the relative dispersion of pressure in the pressed process is also guaranteed, and the pressure resistance effect is guaranteed.
Furthermore, the sheath layer is a rubber material member surrounded by the left side end and the right side end in a clamping manner, and a limiting part 7 is arranged in a gap between the two protruding parts at the left side end and the right side end in the clamping manner. The locating part can be long banding rubber spare, and the restrictive coating passes through the side card mutually, realizes enclosing to be the circular shape sheath, and the installation and the dismantlement of being convenient for, in the building site, the selectivity that pedestrian and equipment can carry out the sheath through the cable in more place installs additional, also material saving when the protection cable.
Furthermore, the restrictive coating is provided with a plurality of sections, arranges along core length direction and lays. The front and the back of the sheath layer are respectively provided with a slot and a plug-in 62, and the plug-in of the adjacent sheath layer is inserted with the slot. Further ensuring the connection stability of the adjacent sheath layers. When the device is disassembled, only two ends are required to be pulled out or pulled out, so that the operation is convenient and fast.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
