Abstract
The utility model discloses a kind of cellular-type cable; comprise three cables core, binder and outer jointing jackets; described three cables core are provided with an inner insulating layer each other; described insulating barrier is provided with concave edge in three arc-shapeds of mating with cable core periphery; described cable core outer setting has described binder, and described binder outer setting has described outer jointing jacket.Three cores of the present utility model are separated each other by inner insulating layer, and inner insulating layer adopts silicon rubber skeleton, effectively ensure that the distance of three cables core and mutually arrange rationally, reduce the sectional area of cable, and the large increase of insulation function, effectively avoids the loss caused because of short circuit, and its structure is simple, convenient applicable, easily manufactured.
Description
Technical field
The utility model relates to electric wire field, is specifically related to a kind of cellular-type cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety Service Efficiency and domestic market occupation rate are all more than 90%.Worldwide, the Chinese electric wire gross output value exceedes the U.S., becomes first electric wire producing country in the world.Along with Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.Because current cable inside is normally provided with the conductor of many mutually insulateds, in use, if insulated wire cores is punctured, touches between each conductor and be short-circuited, making instrument and equipment damaged, even cause serious security incident.
Therefore, need badly at present one can signal transmission again can transferring electric power, and can to prevent because insulating barrier is damaged to the cable causing instrument and equipment short circuit.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of good insulation preformance and the good cellular-type cable of electromagnetic compatibility.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cellular-type cable; comprise three cables core, binder and outer jointing jackets; it is characterized in that: described three cables core are provided with an inner insulating layer each other; described insulating barrier is provided with concave edge in three arc-shapeds of mating with cable core periphery; described cable core outer setting has described binder, and described binder outer setting has described outer jointing jacket.
Concrete, described cable core comprises load-bearing core and protective layer, and described protective layer is coated on the outside of described load-bearing core by winding process.
Concrete, described inner insulating layer is silicon rubber material.
Preferably, described three are filled with stranding packing material between cable core and inner sheath.
Concrete, described binder is that copper strips is wrapped or aluminium-plastic tape is wrapped.
The utility model has the following advantages and beneficial effect compared to existing technology:
Three cores of the present utility model are separated each other by inner insulating layer, and inner insulating layer adopts silicon rubber skeleton, effectively ensure that the distance of three cables core and mutually arrange rationally, reduce the sectional area of cable, and the large increase of insulation function, effectively avoids the loss caused because of short circuit, and its structure is simple, convenient applicable, easily manufactured.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of the utility model cable.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1; the present embodiment provides a kind of cellular-type cable; comprise three cables core 1, binder 2 and outer jointing jacket 3; described three cables core 1 are provided with an inner insulating layer 4 each other; described insulating barrier 4 is provided with concave edge in three arc-shapeds of mating with cable core periphery; described cable core 1 outer setting has described binder 2, and described binder 2 outer setting has described outer jointing jacket 3.
Described cable core 1 comprises load-bearing core 101 and protective layer 102, and described protective layer 102 is coated on the outside of described load-bearing core 101 by winding process.Protective layer voluble wrapping, in the outside of load-bearing core, enhances the protection to load-bearing core, and tensile strength and resistance to wear strengthen, and effectively eliminate the possibility that electric wire is damaged.
Described inner insulating layer 4 is silicon rubber material.Silicon rubber has the performances such as excellent thermal endurance, cold resistance, dielectricity, resistance to ozone and resistance to atmospheric aging, the outstanding performance of silicon rubber is that serviceability temperature is broad, can at-60 DEG C (or lower temperature) to+250 DEG C (or higher temperature) Long-Time Service.
In addition, silicon rubber also especially easily processing and manufacturing.Silicon rubber easily flows, thus can the mold pressing when energy consumption is lower, roll, extrude.
As a kind of embodiment, between described three cables core 1 and inner sheath 2, be filled with stranding packing material 5.Insert stranding packing material 5 in space between cable core 1 and inner sheath 2, be convenient to binder 2 and three cables core 1 integrally wrapped up the cable being configured as circle or oval cross section, and strengthen compressive property and the shock resistance of cable.
Described binder 2 is that copper strips is wrapped or aluminium-plastic tape is wrapped.Adopt that above-mentioned copper strips is wrapped or aluminium-plastic tape is wrapped, can prevent three cables core from producing the interference of electric fields well.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
Claims (5)
