Shown in reference picture 2, for the utility model internal structure is better described, now its manufacturing process is specifically described such as
Under：
1st, from the NTC thermistor 6 of glass-encapsulated ring bag NTC chips, glass outer size in below 2.0mm, and
Chip lead penetrates high temperature resistant sleeve pipe 5, is first used as high temperature resistant sleeve pipe 5 by the use of heatproof polyimides PI pipes here.Each NTC temperature-sensitives electricity
One section of more than 380 degree heatproof polyimides PI pipe of set realizes insulation on the chip lead of resistance 6.
2nd, from being wrapped up by stainless (steel) wire 1 and the electric wire 2 of more than 380 degree of internal material heatproof, stainless (steel) wire 1 use 304
Steel.Electric wire 2 is stripped out into the lead of electric wire 2,1 chip lead for having assembled high temperature resistant sleeve pipe 5 is reached 380 degree or higher with heatproof
The lead of the electric wire 2 progress high-temperature electric fluid welding of temperature connects or welding welding, reaches firm, conducting；Another 1 chip lead with it is described not
The rust riveting of steel mesh 1 reaches firm, conducting.
3rd, PTFE pyrocondensations molded cannula 4 is placed on outside the NTC resistance chip to the lead of electric wire 2 and chip lead bond pad locations
Side carries out pyrocondensation, reaches NTC resistance chip, chip lead, the sealing of the lead binding site of electric wire 2 and high-temperature resistant result.Here,
PTFE pyrocondensations molded cannula 4 is beyond NTC resistance chips 2mm or so.
4th, by the composition product Jing Guo above-mentioned steps below the upper end of PTFE pyrocondensations molded cannula 4 10mm or so, electricity
The lead of line 2 and 10mm right positions above die wire bond point, carry out the iron fluorine that high temperature resistant outer layer is PTFE and internal layer is FEP
The hot-melting sealed of tengential belt glue pyrocondensation molded cannula 3, to carry out welding point insulating and water-proofing treatment.
5th, by complete above-mentioned steps composition product penetrate in stainless steel tube 8, insert lower end in, and carry out fill high temperature without
Machine glue or equal high temperature fixing glue, e.g., add high temperature inorganic glue and carry out secondary waterproof and fixation, prevent inside chip and lead
Abjection.
6th, the other end of electric wire 2 is drawn from the opening of the upper end of the stainless steel tube 8 again.Stainless steel tube 8 carry out bending with
Machinery press against, and by the way that stainless steel tube 8 is flattened, indent, fastening electric wire 2 and stainless steel tube 8, can further increase lead external force
Under pulling capacity.
The advantages of this technology, is on the premise of meeting above-mentioned consumer market demand, goes for single Teflon
Line weaves steel mesh class and twin-core Teflon line braiding steel mesh class product, goes for one-level diameter steel pipe and two level diameter steel
Pipe, applicable elements are broader, and when weaving steel mesh class product suitable for single Teflon line, cost has more cost performance.
The present embodiment is insulated by the high temperature resistant sleeve pipes 5 such as heatproof polyimides PI pipes and PTFE pyrocondensations molded cannula 4, is led to
