The cable component comprises a cable, an air passage and connectors connected on two ends of the cable, wherein two ends of the air passage are correspondingly connected on an interface of the air passage on two connectors, and the air passage is spirally coiled by one end of the cable on the outer surface of the cable and extends to the other end of the cable. The air passage of the component and the cable form a whole, the structure is compact, when in use, even when the air passage is bended along the cable, the air passage can not generate dead bending, thereby preventing the air passage from cracking due to damages and preventing the generation of gas leakage phenomena, and guaranteeing the performance of the whole machine and normal work, and simultaneously, the cable has better flexibility to achieve the effect of preventing bending. The cable component connecting equipment provided by the utility model is used in whole machines, and is particularly used in occasions when gas which may generate damages such as high pressure nitrogen and the like is input into the air passage, thereby avoiding that the air passage is bended and cracked to leak gas to generate hidden danger, and the use is extremely safe.
Description
Technical field
The utility model relates to a kind of cable assembly.
Background technology
Cable assembly is that electric connector and electric wire are directly made the electric equipment products of one by certain termination mode and means of defence, and it can directly realize being electrically connected between equipment and the equipment.But along with development of science and technology, complete machine miniaturization, synthesization have become trend, and this cable assembly that just requires to connect distinct device also should develop to miniaturization, direction integrated, synthesization, to adapt with complete machine.
For these reasons, a kind of existing cable assembly that is electrically connected and has high-pressure gas circuit to connect has appearred, this cable assembly comprises cable and is connected to the connector at cable two ends, be provided with electric contact piece and air-path interface on each connector simultaneously, electric contact piece and the corresponding connection of heart yearn in the cable, the air-path interface on two terminal adapters connects by a tracheae.In this cable assembly because its tracheae and cable are discrete settings, when in cable assembly is used, needing to bend or be given a shock, bending also can take place thereupon or be given a shock in tracheae, tracheae causes cracking gas leakage with regard to being easy to generate dead folding like this, influence machine performance even cause cisco unity malfunction, gas in case of logical high pressure nitrogen in the tracheae etc. can damage also can bring safety problem.
The utility model content
The purpose of this utility model provides the cable assembly that has gas circuit that a kind of cable bending does not damage tracheae, prevents because of the impaired phenomenon that produces gas leakage of tracheae bending.
For achieving the above object, the utility model adopts following technical scheme: a kind of cable assembly that has gas circuit, comprise cable, tracheae and be connected the connector at cable two ends, the two ends correspondence of described tracheae is connected on the air-path interface on two connectors, and described tracheae twines the other end that extends to cable by cable one end spiral on the outer surface of cable.
Also be provided with the polyamide fibre silk braid on the outer surface of cable, described tracheae is spirally wound on outside the polyamide fibre silk braid.
The tracheae outsourcing of twining at spiral is covered with overcoat.
Described overcoat comprises insulating barrier and canvas layer from inside to outside, and the two ends of overcoat are fixed on the afterbody annex of corresponding connector by lashings.
Described cable is the multicore shielding cable, and this cable comprises shielded conductor and non-shielded conductor, and the outermost layer of shielded conductor is a screen; The a branch of center cable of the center of cable for constituting by at least one shielded conductor, the outer cable layer that is placed with two-layer at least even level that surrounds successively of this intrafascicular heart cable, the cable layer that is in odd-level is surrounded by parallel the arranging of non-shielded conductor, and the cable layer that is in even level is walked abreast by shielded conductor, and contacting arranges surrounds; Be adjacent between the cable layer, between each adjacent cable layer, be equipped with the lead fixed rete at the center cable.
The screen of described shielded conductor is a woven shield.
Described lead fixed rete is the polytetrafluoroethylene film layer.
In the utility model, tracheae adopts the mode that is spirally wound on the cable surface to extend to the other end of cable from an end of cable, tracheae and cable have constituted one, compact conformation, in use, even if tracheae is along with cable bends, tracheae can not produce dead folding yet, has prevented that therefore tracheae from because of damaging the generation that cracking causes gas leak phenomenon, having ensured the carrying out of machine performance and operate as normal, simultaneously make cable have better pliability again, reach the effect of anti-bending.The cable assembly connection device that in complete machine, uses the utility model to provide, especially need to use in the occasion of the logical gas that can damage such as high pressure nitrogen etc. in tracheae, stopped to cause the hidden danger of personal safety, used fool proof because of the gas leakage of tracheae bending cracking.
Cable in the utility model is the multicore shielding cable, the layer structure that this cable adopts shielded conductor cable layer and non-shielded conductor cable layer alternately to constitute, and the adjacent shielded conductor contact in the shielded conductor cable layer is arranged, make the mutual conducting of screen of each shielded conductor, formed one deck screen, the non-shielded conductor that is positioned at its internal layer has been implemented shielding.Because non-shielded conductor does not have screen, its external diameter is less than the external diameter of the shielded conductor of same specification, so the utility model can reduce the outside dimension of multi-core cable effectively, has guaranteed the shielding requirements of non-shielded conductor simultaneously again, in addition, also increased the suppleness of cable.This cable is that cable assembly realizes miniaturization, integratedly made contribution.
