Abstract
The utility model relates to a cable and a train comprising the cable. The cable comprises one or more data line cores (21-24) for transferring data and a sleeve (4) made of cross-linked silicon rubber for encircling one or more data line cores.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of jumper cable (jumper cable) that is connected between the railway car, and the train that comprises this kind cable.
Background technology
In train, especially high ferro train field; Between each compartment of train, be connected with jumper cable; So that Data transmission between each compartment (comprising control signal, network data etc.) and conduct power additionally also sometimes, the equipment in the railway carriage or compartment of buying car in installments uses.Therefore, this jumper cable is a kind of integrated form cable that combines control cable, data cable and power cable.The typical structure of this cable comprises the one or more data core that is used for Data transmission, and the overcoat that surrounds said one or more core.Alternatively, this cable also can comprise the electric power core that is used for conduct power.
Because relative motion and vibration can take place in each compartment in the train driving process, so correspondingly, the above-mentioned jumper cable that is connected between each compartment becomes a kind of moving component, can go through frequent bending, stretching and vibration by long-time ground warp.In addition, above-mentioned jumper cable also usually is exposed in the abominable external environment condition, is easy to suffer extraneous damage.Like this, in order to guarantee the operate as normal of compartment and equipment thereof, said jumper cable need have special high-performance and high security.Particularly; Said jumper cable need have good mechanical performance, electric property, fire-resistant heat resistance, anti-chemical performance, weather-resistant property or the like; Especially, also should have good flexibility and dynamic fatigue property (can stand) up to for example 500,000 times shuttling movement.
Yet the flexibility of existing jumper cable and dynamic fatigue property are not good, and thermal endurance, weather-resistant property and anti-chemical performance are also relatively poor, and mechanical performances such as resistance to wear and tear resistance are not high yet, thereby useful life is short.
The utility model content
The utility model is intended to solve above-mentioned one or more problems of the prior art, and a kind of jumper cable with good flexibility, dynamic fatigue property, heat resistance, anti-chemical performance, weather-resistant property, resistance to wear and tear resistance promptly is provided.
Above-mentioned purpose can be realized that this cable comprises by the cable according to the utility model: the one or more data core that is used for Data transmission; With surround overcoat said one or more data core, that process by crosslinked silicon rubber.
According to a kind of favourable configuration, said silicon rubber is based on the silicon rubber of polysiloxane polymer.In addition, said silicon rubber also is preferably fire-retardant low smoke, zero halogen silicon rubber.
Said data core can comprise the conductor and the insulating sleeve that surrounds said conductor of tape insulation layer.Wherein, the conductor of at least one said data core can have the said insulating barrier of being processed by thermoplastic, and said thermoplastic for example is a polyethylene.
Advantageously, said cable also can comprise by said overcoat surround and with the parallel electric power core that be provided with, that be used for conduct power of said one or more data core.
According to the favourable configuration of another kind, said cable also can comprise the outer shielding layer that is arranged on the inboard of said overcoat and surrounds said one or more data core.
The utility model also provides a kind of train that comprises a plurality of compartments and aforesaid cable, and wherein said cable is connected between said a plurality of compartment as jumper cable.
According to the cable of the utility model because the overcoat of its particular design and can have good flexibility (can realize very little minimum bending radius), dynamic fatigue property and (can stand up to for example 500; 000 time shuttling movement), heat resistance, anti-chemical performance, weather-resistant property, resistance to wear and tear resistance or the like; Can withstand frequent bending, stretching and vibration; And can effectively resist the infringement of harsh environment, thereby Data transmission and electric power reliably.
Description of drawings
The accompanying drawing that comprises in this manual and constitute this specification part illustrates the illustrative embodiments of the utility model, and is used to explain the principle of the utility model with illustration, in the accompanying drawings:
Fig. 1 is the sectional elevation according to an embodiment of the cable of the utility model.
Embodiment
The cutaway view of Fig. 1 shows the section structure according to an embodiment of the cable 1 of the utility model.Cable 1 comprise the one or more data core 21-24 that is used for Data transmission, with parallel electric power core 3 that is used for conduct power that is provided with of said data core and the overcoat 4 that surrounds said data core and electric power core, also can comprise being arranged on the inboard of overcoat 4 and surrounding the outer shielding layer 5 of all cores and be filled in the filler 6 between each core.Said data core comprises the conductor and the insulating sleeve that surrounds said conductor of tape insulation layer, also can comprise the screen that is arranged between conductor and the insulating sleeve.In order to realize high performance data passes, the insulating barrier of the conductor of said data core can be processed by thermoplastic (for example, polyethylene).The insulating sleeve of said data core can be processed by low smoke and zero halogen material such as EVA (being ethylene-vinyl acetate copolymer).In the present embodiment, said data core can comprise coaxial cable core 21, twin-core conductor thread core 22, four-core conductor thread core 23 and six core conductor cores 24.The utility model is not limited thereto, but also can adopt any other appropriate format well known in the art and quantity data core according to application scenario and requirement but obviously.This shows; Cable according to the utility model is to have combined data cable (for example; Be used in WTB (radial type train bus-line) and MVB (MVB) data cable on the high ferro train), the integrated form cable of control cable and power cable, can be used for various data and electric power such as delivery network data, control signal.In addition, form and be simple data cable according to also can inquire after the health of one's parents according to circumstances slightly wherein electric power core of the cable of the utility model.
Overcoat 4 according to the cable of the utility model has particular design, and it is the overcoat of being processed by crosslinked silicon rubber.Preferably, overcoat 4 is overcoats of processing by based on the fire-retardant low smoke, zero halogen silicon rubber of polysiloxane polymer.Main component is the performance that this silicon rubber of polysiloxane polymer has a series of excellences after crosslinked; The infringement that especially can stand frequent bending, stretching and vibration for a long time and effectively resist harsh environment; Thereby feasible cable according to the utility model can have good flexibility (can realize very little minimum bending radius), dynamic fatigue property (can stand up to for example 500,000 times shuttling movement), heat resistance, anti-chemical performance, weather-resistant property, resistance to wear and tear resistance etc.
Owing to have an above-mentioned good performance, especially be suitable for being connected according to the cable of the utility model between each compartment of train with Data transmission and electric power.But, obviously also can be applicable to needs Data transmission and/or electric power and require cable can stand other occasion or the field that bends, stretches and/or vibrate and effectively resist the infringement of harsh environment for a long time according to the cable of the utility model.
