Abstract
The invention provides an electric heating pipe for a special type air conditioner, which includes a flexible circuit conductor, a heating wire, a stainless lead-out rod, 703 sealant, a silicon resin fiber sleeve, and an environment-friendly heat shrink pipe, and is characterized in that external threads are machined at the left end of the stainless lead-out rod, and are sleeved with the spiral heating wire for spot welding; at the right end of the stainless lead-out rod, the stainless lead-out rod is argon-arc welded with the copper core of the flexible circuit conductor, the 703 sealant is filled at the stainless lead-out rod and the copper core of the flexible circuit conductor and at the excircle of the welding part of the stainless lead-out rod and the copper core of the flexible circuit conductor, and the stainless lead-out rod and the copper core of the flexible circuit conductor are sleeved with the silicon resin fiber sleeve; the 703 sealant is filled at the space between the right end surface of the silicon resin fiber sleeve and the end surface of the flexible circuit conductor, and the silicon resin fiber sleeve and partial excircle of the flexible circuit conductor are sleeved with the environment-friendly heat shrink pipe. The heating wire and the stainless lead-out rod of the electric heating pipe are well connected, so that burnout of the heating wire is avoided; besides, the insulating property of the electric heating pipe is not weakened, the special type air conditioner can work normally, and the generation of electric shock hazard is avoided.
Description
Technical field
The present invention is a kind of electric heating tube of using on special air conditioner.
Background technology
When special air conditioner heats, equipped number cover electric heating tube energising work.Each is comprised of every cover electric heating tube two electric heating tubes, between two electric heating tubes, with flexible conductor, connects.The connected mode of the heating wire of original electric heating tube and stainless steel eduction rod is: by the afterbody of helical form heating wire, stretching one section, be placed in the straight trough of stainless steel eduction rod left end, adopt the method for hitting of pressing, make the flow of metal on straight trough both sides, by one section stretching heating wire compacting in the straight trough of stainless steel eduction rod.The connected mode of original electric heating tube stainless steel eduction rod and flexible conductor copper core is: in the internal thread of the right-hand member external screw thread precession copper sleeve of stainless steel eduction rod, copper sleeve and flexible conductor copper core carry out crimping.Outside stainless steel eduction rod and copper sleeve, on garden, inject fluid sealant, put the alkali-free glass fibre sleeve pipe.Magnesia powder end face through tamping and the gap of alkali-free glass fibre box face, and the gap of the interior garden of stainless steel protection sleeve pipe and alkali-free glass fibre sleeve pipe, inject fluid sealant.Between alkali-free glass fibre sleeve pipe and copper sleeve right side and flexible conductor end face, inject fluid sealant.
Above connected mode easily produces following problem:
1, adopt and press the method for hitting to connect heating wire and stainless steel eduction rod, sometimes do not press tightly, loose contact, this place's heating wire easily blows.
2, copper sleeve is connected with the crimping of flexible conductor copper core, the outer garden of copper sleeve is larger, the outer garden of copper sleeve puts the alkali-free glass fibre sleeve pipe, gap in the outer garden of copper sleeve and alkali-free glass fibre sleeve pipe between garden is very little, the fluid sealant that is infused on the outer garden of copper sleeve is pressed against the gap between garden in the outer garden of the larger stainless steel eduction rod in gap and alkali-free glass fibre sleeve pipe, the fluid sealant that injects between alkali-free glass fibre sleeve pipe and copper sleeve right side and flexible conductor end face becomes lonely a pile, under the effect of assembling or other external force factor, this place's fluid sealant is easy to crack, moisture enters from cracking, cause the electric heating tube decreasing insulating, the special air conditioner cisco unity malfunction, and can produce Danger Electric shock risk.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric heating tube is provided, and heating wire is connected well with the stainless steel eduction rod, and the heating wire of junction can not blow; The stainless steel eduction rod is connected rationally with flexible conductor copper core, and under the effect of assembling or other external force factors, the fluid sealant of injection can not ftracture, and the electric heating tube insulation property can not descend, and special air conditioner can work, and can not produce Danger Electric shock risk.
For solving the technical scheme that above technical problem adopts, be such: at stainless steel eduction rod left end, part stainless steel eduction rod processes external screw thread, and spiral heating wire is enclosed within the external screw thread place, carries out spot welding, and heating wire is welded on the stainless steel eduction rod.At the right-hand member of stainless steel eduction rod, stainless steel eduction rod and flexible conductor copper core carry out argon arc welding, on stainless steel eduction rod, flexible conductor copper core and weld De Wai garden, inject 703 fluid sealants, put humidity resistance silicon resin fiber sleeve preferably.The moisture seal performance of 703 fluid sealants is better.Magnesia powder end face after tamping and the gap of silicon resin fiber sleeve end face, and the gap of stainless steel protection Tao Nei garden and silicon resin fiber sleeve, inject 703 fluid sealants.Between silicon resin fiber sleeve right side and flexible conductor end face, inject 703 fluid sealants.Outside silica gel fiber sleeve and part flexible conductor, on garden, put the environment-friendly type heat-shrink tube.
Adopt above technical scheme, its effect is apparent:
1, heating wire is connected well with the stainless steel eduction rod, and contact is reliable, and heating wire can not blow.
2, stainless steel eduction rod and flexible conductor copper core carry out argon arc welding, the outer garden of weld is less, the gap that puts silicon resin fiber sleeve is larger, can hold 703 more fluid sealants, 703 fluid sealants that inject between these place's 703 fluid sealants and silicon resin fiber sleeve right side and the flexible conductor end face curing molding that connects together, under the effect of assembling and other external force factor, 703 fluid sealants can not ftracture, the electric heating tube insulation property can not descend, special air conditioner can work, and can not produce Danger Electric shock risk.
3, cover has the environment-friendly type heat-shrink tube, and insulation property are more stable.
