Accompanying drawing explanation
Fig. 1 is aerospace polyimide film high-voltage flat cable structural representation.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the utility model further.
As shown in Figure 1, aerospace polyimide film high-voltage flat cable, it comprises the cable body extended linearly, and this cable body is flat cable structure, and described flat cable structure is formed by external force compacting insulation layer structure.
Described flat cable structure has and to be walked abreast conductor wire core 1 by two cores that the thin silver-gilt copper wire of multiply (more than two strands or two strands) is stranded, and at the insulation layer structure 2 that conductor wire core external application polyimide film is suppressed by binding agent, conductor wire core is parallel to be arranged in flat cable structure as corresponding conductive structure.
Insulation layer structure is described in detail in detail below:
As a kind of embodiment, it is that (K value sets K as required that described polyimide film is directly set around spacing, ensure safe distance each other can) two cores walk abreast outside conductor wire core and form flat cable structure, here, directly be wound on polyimide film the requirement that conductor wire core outside can reduce technique, be conducive to enhancing productivity and reduce corresponding cost, spacing is that two cores of the K polyimide film sticked together by binding agent between conductor wire core that walks abreast forms isolation structure, because this embodiment is directly that polyimide film is outside around conductor wire core, on conductor wire core, independently polyimide film is not set, Given this, we utilize binding agent to be filled up with polyimide film completely in the gap between conductor wire core, thus the isolation structure that effectively forms each other.Described flat cable structure is that multilayer (more than two-layer or two-layer) polyimide film coiling forms, and between each polyimide film, be provided with binding agent between polyimide film and conductor wire core.Another isolation structure for the gap between conductor wire core can adopt insulation spacing block, this insulation spacing block is located between two conductor wire cores, and insulation spacing block contact conductor wire core side is provided with the circular groove structure coordinated with conductor wire core, so that conductor wire core embeds wherein keep stability, for the environment of exploration cable body interior, described insulation spacing block can set temperature transducer, humidity sensor, described temperature sensor, the signal output part of humidity sensor is connected to controller (such as PLC), this controller is connected to warn device, such as warning light, so that cable body internal environment occurs that difference can be easily noticed by the users timely.
Another kind as this case is selected, described insulation layer structure comprises: be wound in the core polyimide film winding structure layer outside each conductor wire core, each conductor wire core independently arranges polyimide film and has effectively completely cut off conductor wire core, but this scheme technique for coiling adds, and virtually reduces production efficiency; Two core polyimide film winding structure layers are coiled into an integrally-built outer polyimide film winding structure layer.Wherein, between the polyimide film in described core polyimide film winding structure layer, between polyimide film and conductor wire core, binding agent is provided with; Between described core polyimide film winding structure layer, between outer polyimide film winding structure layer and core polyimide film winding structure layer, be provided with binding agent.
As the product of this case, polyimide film and conductor wire core form hermetically-sealed construction tool by binding agent and have the following advantages: insulating layer material itself has excellent humidity and chemical solvent floods characteristic, adhesion between the insulating barrier suppressed by binding agent and conductor wire core, form sealing overall, these 2 make the humidity of electric wire and chemical solvent saturating machine remarkable.
Arbitrarily cable is twisted for preventing outside, the surface of described cable body is provided with prevents turning round colour band, this is anti-turns round colour band and extends linearly mode along cable and arrange, when it is not in same straight line then adjustable, avoids Exterior cable insulation system twist and affect the use of cable.
For ease of putting the trend of this cable under the environment of dark preferably in order, the surface of described cable body can arrange super crystal lattice material.
The foregoing is only preferred implementation of the present utility model, protection range of the present utility model is not limited in above-mentioned execution mode, and every technical scheme belonging to the utility model principle all belongs to protection range of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection range of the present utility model.
