In the utility model, bellows and thermal insulation layer are tubulose, and its radial edges refers to its edge along its length, but not the edge at two ends.Its radial edges is closed, forms closed tube, and side does not have opening; Radial edges is not closed, forms not closed tube, and there is opening side.
In the utility model, engine wiring harness comprises power line, holding wire etc.
In the utility model, bellows is preferably the inc bellows of radial edges, can reduce costs like this.
According to another embodiment of the utility model, in thermal insulation layer, aluminium foil layer is outer, and factice layer is middle level, and casing play is internal layer.
In the utility model, the heat aging property of aluminium foil layer is good, and it act as reflective thermal radiation, and carries out heat insulation.The effect of factice layer is that aluminium foil layer and casing play are bonded together.Casing play can adopt the material with supporting role, and aluminium foil layer is played a supportive role.
According to another specific embodiment of the utility model, casing play comprises fiberglass layer and layer of silica gel, and fiberglass layer is pressed close to factice layer.Fiberglass layer is glass fabric layer, and its physical structural characteristic is good, is suitable for supporting as skeleton.Layer of silica gel is used for preventing that glass fibre from overflowing, and guarantees safety.In manufacturing process, layer of silica gel can partly be infiltrated in fiberglass layer.
In the utility model, bellows, aluminium foil, factice, glass, silica gel are the material that cost is low, thereby wire harness instlated tubular of the present utility model not only possesses enough heat-proof qualities, and with low cost.
According to another embodiment of the utility model, the radial edges of thermal insulation layer is closed.
According to another embodiment of the utility model, the radial edges of thermal insulation layer is mutually bonding.
According to another embodiment of the utility model, the radial edges of thermal insulation layer is sewed up mutually.
According to another embodiment of the utility model, the radial edges of thermal insulation layer is sewed up mutually by aramid line.
Certainly, the utility model can also pass through alternate manner of the prior art, and such as stitching or fastening etc., to realize radial edges closure.
According to another embodiment of the utility model, wire harness instlated tubular further comprises for limiting the locating part of thermal insulation layer and bellows relative motion.
According to another embodiment of the utility model, locating part comprises a plurality of bands that are enclosed within outside thermal insulation layer, and a plurality of bands band spaced apart, by band is set, can be fixed on thermal insulation layer on bellows, reduces and takes up room simultaneously.
Band is according to another concrete real-time mode of the utility model, and aluminium foil layer thickness is 0.015-0.02 millimeter, and factice layer and casing play gross thickness are 0.40-0.44 millimeter, adopts the as above thermal insulation layer of thickness, can improve heat-proof quality.
Compared with prior art, the utility model possesses following beneficial effect:
In the utility model, with bellows, hold engine wiring harness and engine wiring harness is led, the aluminium foil layer in thermal insulation layer possesses good heat-proof quality.In the utility model, bellows is cheap for manufacturing cost, and aluminium foil etc. is the material that cost is low, thereby wire harness instlated tubular of the present utility model reduced cost than existing heat-insulating technique, does not lose effect of heat insulation simultaneously.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
