Abstract
The utility model relates to a heavy connection cable of locomotive body for connecting the electric energy or electrical signal between the railway locomotive body and the vehicle body, belonging to the cable technical field, comprising an outer sheath, a first isolation layer, an insulated conductor and a shielding conductor; the insulated conductors of five units are evenly distributed outside of the shielding conductor; certain hemp cords are filled in the gap between the insulated conductors, and the first isolating layer is enwrapped outside of the insulated conductor; the outer sheath is arranged outside of the first isolating layer. The utility model has the advantages that the conductors can be effectively twisted, and the protection function for the insulated conductor is enhanced due to the added outer sheath, thus the cable can be widely used in the heavy connection cable of locomotive body.
Description
Technical field
The utility model relates to the cable technology field, refers in particular to the heavy tie cable of locomotive car body that the electric energy between a kind of rail locomotive car body and the car body or the signal of telecommunication are connected.
Background technology
Along with the development of rail locomotive, the electrifing degree on the locomotive requires more and more higher, and the electric energy between car body and the car body and the transmission of the signal of telecommunication are more and more; So require the cable between car body and the car body more and more.And mostly the cable of transmission of control signals is the core of small bore, and the trouble that not only connects up when being connected between car body and the car body is safeguarded inconvenience, and destroys cable core easily owing to extraneous factor in train travelling process.
Summary of the invention
The technical problem that the utility model solves is to provide the heavy tie cable of electric energy and signal transmission between a kind of connection locomotive car body of special use and the car body; Can effectively these cores be twisted together, and increase one deck oversheath, strengthen protective effect insulated wire cores in these core outsides.
The technical problem that the utility model solves is achieved by the following technical solution: include oversheath, first separator, insulated wire cores and shielding core, distributing the uniformly outward insulated wire cores of 5 unit of shielding core, space between the insulated wire cores is filled with the rope made of hemp, insulated wire cores coated outside first separator, the first separator peripheral hardware oversheath.
Described shielding core comprises braid, second separator, insulating barrier, core conductor, the rope made of hemp, establishes four core conductors in second separator, core conductor outer wrapping insulating barrier; The rope made of hemp is filled in space between the insulating barrier; The second separator peripheral hardware braid.
Insulated wire cores comprises insulating barrier, core conductor; Establish the several wire core conductor in the insulated wire cores, every core conductor outside is covered with insulating barrier, insulated wire cores unit outer surface adopt cotton yarn dredge around.
First separator is formed by two-layer cotton braid.
The utility model insulated wire cores major function is the transport vehicle of the electric energy and the signal of telecommunication, and it restraints the structure of afterwards twisting earlier makes cable that good bending property be arranged.External sheath layer promptly plays machinery and chemoproection effect as the main auxiliary element of cable.The structure of insulating barrier is the interference of shielding outside electric field.First separator, dredge around layer, play insulated wire cores each other and with the slide relative between oversheath,, prevent unbalanced stress and local disconnected core phenomenon occurs in bending, to eliminate stress as general auxiliary element.And two-layer Polyamide Yarns braiding structure is for the pull resistance that strengthens cable with to the durability of long-term tension.It is 100 ℃ that the utility model cable allows working temperature for a long time, possess anti-ozone, ultraviolet ray and humidity characteristic, oil resistant, flame-retarding characteristic are arranged, can between the car body of rail locomotive and car body, use, save the trouble of wiring, avoided in use extraneous factor to the destruction of insulated wire cores.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing is the utility model construction of cable schematic diagram.
Embodiment
As shown in drawings, the utility model includes oversheath 1, first separator 2, insulated wire cores 3 and shielding core 4, the insulated wire cores 3 of shielding core 4 outer 5 unit that distributing uniformly, the space between the insulated wire cores 3 is filled with the rope made of hemp 5, insulated wire cores 3 coated outside first separator 2.First separator 2 is formed by two-layer cotton braid, its peripheral hardware oversheath 1.Described shielding core 4 comprises in braid 6, second separator 7, insulating barrier 8, core conductor 9, the rope made of hemp 5, the second separators 7 establishes four core conductors 9, core conductor 9 outer wrapping insulating barriers 8; The rope made of hemp 5 is filled in space between the insulating barrier 8; Second separator, 7 peripheral hardware braids 6.Insulated wire cores 3 comprises insulating barrier 8, core conductor 9; Establish several wire core conductor 9 in the insulated wire cores 3, every core conductor 9 outsides are covered with insulating barrier 8, insulated wire cores 3 unit outer surfaces adopt cotton yarns 10 dredge around.
In the insulated wire cores 3 of 5 unit of the utility model cable, there is the insulated wire cores 3 of four unit to be distributed with 8 core conductors 9, wherein, the center is 1,7 on every side; Another insulated wire cores 3 is 7 core conductors 9 of distribution evenly, and rope made of hemp 5 is filled at its center.
Aforementioned core conductor 9, adopting filament diameter is that the zinc-plated annealed copper skein silk of 0.20mm closes and forms, performance meets GB/T 3956; Second separator 7 is the polyester film of 0.025mm for thickness, and it is the Polyamide Yarns braiding of 0.25mm that first separator 2 adopts two-layer line diameter, and oversheath 1 adopts the flame-proof cross-linking material, and thickness is 3.5mm, and the maximum gauge of cable is 40mm.
