Description
Technical field
The utility model relates to a kind of pre-branched cable of vertical erection, particularly the pre-branched cable that vertically sets up of a kind of vertical shaft, crane span structure, house.
Background technology
Pre-branched cable is the substitute products that skyscraper median generatrix groove is powered, and is cable producer when producing main cable, by the cable of user's design drawing prefabricated branch core.Cable producer will divide core branch to be manufactured on main cable in advance, core branch cross-sectional sizes and point core branch length etc. is divided to determine according to designing requirement, branch joint connection place after completing, an entirety is effectively bonded to master, point original external sheath layer of cable, compared with processing cable branch joint or bus duct technology with traditional job site, greatly shorten construction period, drastically reduce the area Master Cost and operating expenses, ensure that the reliability of distribution.
The appearance of prefabricated branch cable changes the history making cable end for a long time at the construction field (site), is a quantum jump of low-voltage distribution system electric wire.Have power supply reliable, easy for installation, account for the advantages such as construction area is little, failure rate is low, low price, freedom from repairs maintenance, being applicable to ac rated voltage is in 0.6/1KV distribution line.Be widely used in vertical supply in upper mesophere building, residential building, mall, hotel, hospital's electric shaft, be also applicable to the electric power systems such as tunnel, airport, bridge, highway.Along with the speed of the various capital construction of China, development of real estate is accelerated, the application type requirements of market to prefabricated branch cable is on the increase, performance requirement improves constantly, such as develop into the requirements such as fire-retardant, fire-resistant, LSOH anti-flaming from initial common cable, heavy in section is developed into by small bore, develop into multicore etc. by initial single core, the application prospect of prefabricated branch cable is boundless.
But the pre-branched cable that the gravity born for vertically arranged pre-branched cable breakout and pulling force are installed relative to level is much bigger, this problem of consideration that present pre-branched cable is not deep.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pre-branched cable of vertical erection, and by arranging prefastened mode, the gravity that increase breakout can bear and pulling force, prevent breakout from coming off, increase the globality of pre-branched cable.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pre-branched cable of vertical erection comprises main core wire, be connected to the core branch wire of main core cable and be located at the insulating barrier of main core wire and core branch wire outer surface, propping up heart wire connectors is connected on main core wire, described connector comprises main clamp, sub-folder tool, strengthens fixed network, main clamp is connected by connecting plate with sub-folder tool, main clamp is fixed on main core wire, sub-folder tool is fixed on core branch wire, strengthens fixed network and is made up of rubber;
Described enhancing fixed network is located in the insulating barrier of main core wire outer surface, is connected with connecting ring by connecting band, and connecting ring connects core branch wire, and sub-folder tool is at connecting ring and strengthen between fixed network.
Further, sub-folder tool respectively establishes with on described connecting ring the magnet that a magnetic pole is identical.
The utility model has the advantage of, except connected main core wire and core branch wire by fixture except, the mode also connecting core branch wire by arranging enhancing fixed network in the insulating barrier of main core wire outer surface arranges and pre-fixes structure, when core branch wire stressed enhancing fixed network can first be out of shape to resist the stressed of core branch wire, thus increase core branch wire fastening force and pulling force.Meanwhile, also there is excellent shock resistance, prefabricated branch cable at body of wall by joint when shaking unaffected (the prefastened structure pre-fixing structure can cushion the strength that body of wall vibrations produce), especially when being stitched by building settlement without any need for measure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the pre-branched cable structural representation that the utility model vertically sets up.
In figure: main core wire 1, core branch wire 2, insulating barrier 3, main clamp 4, sub-folder tool 5, enhancing fixed network 6, connecting band 7, connecting ring 8.
Embodiment
As in Fig. 1, a kind of pre-branched cable of vertical erection comprises main core wire 1, be connected to the core branch wire 2 of main core cable 1 and be located at the insulating barrier 3 of main core wire 1 and core branch wire 2 outer surface, core branch wire 2 connectors is connected on main core wire 1, connector comprises main clamp 4, sub-folder tool 5, strengthens fixed network 6, main clamp 4, sub-folder tool 5(can adopt steel construction or alloy structure), main clamp 4 is connected by connecting plate with sub-folder tool 5, main clamp 4 is fixed on main core wire 1, sub-folder tool 5 is fixed on core branch wire 2, strengthens fixed network 6 and is made up of rubber;
Strengthening fixed network 6 is located in the insulating barrier 3 of main core wire 1 outer surface, and be connected with connecting ring 8 by connecting band 7, it is the part of core branch wire 2 that connecting ring 8 shapes together with core branch wire 2, which is provided with connecting hole, connecting band 7 makes the connecting hole of its one end through connecting ring 8 by steel wire, the insulating barrier 3 of other end perforating branches core wire 2 outer surface is connected (at breakout place with enhancing fixed network 6, the insulating barrier 3 of core branch wire 2 is relatively thick, can by arranging protective layer on connecting band 7, prevent connecting band 7 from leaking electricity, connecting band 7 mainly plays power transmission, be equivalent to be provided with protective layer outside tie point simultaneously, improve the stiffness outside tie point, when tie point is stressed, connecting band can absorb a part of pressure), sub-folder tool 5 is at connecting ring 8 and strengthen between fixed network 6, sub-folder tool 5 is in the below of connecting band 7, connecting band 7 can protect sub-folder tool 5 to prevent outside pressurized.
Preferred version also comprises, and sub-folder tool 5 respectively establishes with on connecting ring 8 magnet that a magnetic pole is identical, can by setting the location learning core branch wire 2 of sub-folder tool 5 magnet or connecting ring 8 magnet relative to main core wire 1 change in displacement situation.
It is not be connected with main core wire core branch wire by pre-fixing structure that setting pre-fixes structure, but first core branch wire and main core wire are carried out being connected, its breakout meets its stiffness connected and intensity, when core branch wire and main core wire are not subject to ectocine, breakout is stressed is core branch wire gravity, then structure is pre-fixed increase by, externally applied forces in opposing use procedure, exempts to keep away externally applied forces and is directly loaded into breakout.
The above embodiments are only optimal technical scheme of the present utility model; and should not be considered as restriction of the present utility model; the technical scheme that protection range of the present utility model should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection range.Namely the equivalent replacement within the scope of this improves, also within protection range of the present utility model.
