Step 1) to prepare coil, at least comprises an improvement polyurethane imines coating at the outside insulating layer coating that is coated with of core in described insulating barrier, described improvement polyurethane imines coating consists of the mixture of 50% polyurethane, 48% polyester-imide and 2% silicon;
Step 2) insulating barrier after applying is placed in to arid region dry;
Step 3) adopts described coil to put down and winds the line in skeleton around method of piling.
As the present invention, further improve, in described step 1), the thickness of described improvement polyurethane imines coating is less than 1.2 microns.
As the present invention, further improve, in described step 2) in, described arid region comprises that 400 degrees Celsius at least three warm areas within the scope of 460 degree celsius temperature.
As the present invention, further improve, in described step 3), the coiling angle of described coil on skeleton is within the scope of 11 ° to 13 °.
As the present invention, further improve, described iron core is by there being the silicon steel sheet laser welding of orientation to form, because utilization of the present invention has the silicon steel sheet of orientation, adopt cylinder method of laser welding to improve magnetic saturation width and reduce magnetic loss heating, reduce coil spontaneous heating in the course of the work.
Owing to having adopted above technical scheme, make new forms of energy fuel pen-type ignition coil of the present invention can make temperature be directly proportional to withstand voltage, be particularly suitable for the use of new forms of energy engine fuel.
Accompanying drawing explanation
The organigram that accompanying drawing 1 is pen-type ignition coil of the prior art;
Accompanying drawing 2 is according to the organigram of new forms of energy fuel pen-type ignition coil of the present invention;
Accompanying drawing 3 is according to the schematic cross-section of primary coil of the present invention and secondary coil.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Shown in accompanying drawing 1, there is shown the organigram of pen-type ignition coil of the prior art, can find out the Structural Tectonics that it adopts groove coiling, skeleton 1 adopts traditional silicon steel disc lamination to manufacture, rib 3 on skeleton 1 forms ten groove winding slots, in the winding slot that coil 2 winds the line on skeleton 1, the pen-type ignition coil of this structure cannot solve the shortcoming of coil high-temperature-resistant high-pressure-resistant.
Shown in accompanying drawing 2 and accompanying drawing 3, new forms of energy fuel pen-type ignition coil in the present embodiment, comprise the coil 2 winding the line on skeleton 1, coil 2 comprises as the core 31 in accompanying drawing 3 and the insulating barrier that is wrapped in core outside, wherein, insulating barrier comprises improvement polyurethane imines coating 32, setting layer 33 and insulating varnish coating 34, and the thickness of improvement polyurethane imines coating 32 is less than 1.2 microns.
Improvement polyurethane imines coating consists of the mixture of 50% polyurethane, 48% polyester-imide and 2% silicon, have under high temperature action, because making the proof voltage ability of enamelled wire, the effect of imines improves, also there is solderability, high temperature resistant, the advantages such as coat of paint is thin, bring very large benefit to durability and the manufacturing process of coil.Above advantage can show by the table one of following comparative test result.
