Description
Technical field
The invention belongs to anti-deicing technical fields, are related to a kind of packaging method of icing detector sheathed heater.
Background technique
The anti-clearing ice technology of aircraft is most important for flight safety, and icing detector is mainly used for tying in aircraft flight
The detection of ice environment, in order to repeat to detect freezing environment, icing detector working end can all install heater, to work
End carries out heating deicing, so that icing detector carries out icing detection again.
Sheathed heater structure used in icing detector is as shown in Figure 1, its outer diameter Φ 2 adds having a size of 1.2 ± 0.05mm of Φ
Heated filament diameter of phi 1 is having a size of 0.5mm.It need to carry out high-frequency welding when being assemblied in product due to sheathed heater, about 700 DEG C of temperature,
Its original encapsulation can be destroyed, and cause insulation performance bad, therefore need to be shelled again heater strip and be packaged to port, but due to
Sheathed heater outer diameter and heater strip diameter are smaller, dial heater strip and encapsulation port is all relatively difficult, qualification rate is low.
Summary of the invention
The purpose of the present invention: proposing a kind of packaged type of sheathed heater, it is effective improve in heater heater strip with
Insulation between shell, it is ensured that sheathed heater can reliably work.
Technical solution of the present invention: a kind of packaging method of sheathed heater, using sheathed heater shell 1, insulation material
Material 2, heater strip 3, welding pedestal 4, heater welding bushing 5, ceramic insulation bushing pipe 6, heater draw capillary 7 and welding bushing
8 pairs of sheathed heaters are fixed and draw heater strip, and packaged type is filled using welding and with insulating cement.
Method includes the following steps:
Step 1: welding pedestal 4 being welded with sheathed heater shell 1, welding manner uses silver brazing；
Step 2, sheathed heater is shelled by size requirement, exposes heater strip 3；
Step 3, the heater strip 3 that heater extraction capillary 7 is stripped out with second step is welded, welding manner is using silver-colored pricker
Weldering；
Step 4, weld cleaned, dried；2~3mm is removed into the end of sheathed heater again, guarantees armouring
High temperature cabonization when heater insulation material 2 is not soldered；
Step 5, heater is put into high-temperature cabinet and is dried, until insulation is met the requirements, then end is sealed
Dress；
Step 6, heater welding bushing 5 and welding pedestal 4 are attached by screw thread；
Step 7, to the cavity sealant pouring and sealing of heater welding bushing 5；
Step 8, heater capillary 7 and welding bushing 8 is drawn to be welded with high temperature soldering.
There are also the steps in the cavity that ceramic insulation bushing pipe 6 is installed on to heater welding bushing 5 after step 6.
Above-mentioned steps 7 are divided to for two steps, first with J168 epoxide-resin glue to the cavity bottom of heater welding bushing 5
2/3 is played to be fixed, seal；Then it is sealed with cavity port of 704 silicon rubber to heater welding bushing 3.
Advantages of the present invention: heater heater strip 3 and heater draw and use welding manner between capillary 7, ensure that and connect
The reliability of touching, reduces contact resistance；It welds and is welded between pedestal 4 and heater housings 1 by silver brazing, guarantee the two
Between leakproofness.High reliablity after packaged type encapsulation, sheathed heater good insulation preformance, qualification rate are high.
Detailed description of the invention:
Fig. 1 is sheathed heater structure chart；
Wherein 1: heater housings；2: insulating materials；3: heater strip.
Fig. 2 is sheathed heater package structure diagram；
Wherein 1: heater housings；2: insulating materials；3: heater strip；4: welding pedestal；5: heater welds bushing；6: pottery
Porcelain insulating bushing pipe；7: heater draws capillary；8: welding bushing.
Specific embodiment:
The invention will be described in further detail with reference to the accompanying drawings of the specification.
Step 1: welding pedestal 4 and the shell of sheathed heater 1 being welded, welding manner uses silver brazing, welding
When sheathed heater need to be fixed, prevent heater strip 3 be broken；
Step 2, sheathed heater is shelled by size requirement, exposes heater strip 3.Since the size and structure of heater are special
Property, slow, carefulness is needed when heater is removed, and prevents heater disconnected by stripping.Heater strip 3 is stripped out by size requirement, by subsequent
Heater strip 3 is drawn in operation, facilitates later period electrified regulation；
Step 3, the heater strip 3 that heater extraction capillary 5 is stripped out with second step is welded, welding manner is using silver-colored pricker
Weldering, this operation purpose reduce contact resistance between the two, guarantee heater heating power；
Step 4, heater port is cleaned, the welding agent used when by welding cleans up, and then dries.Then right
Heater port removes 2~3mm again, exposes new heater strip 3 and insulating materials 2；
Step 5, sheathed heater is put into high-temperature cabinet to dry, is insulated after meeting the requirements to heater end J168
Epoxide-resin glue is tentatively sealed；
Step 6, heater welding bushing 5 and welding pedestal 4 are attached by screw thread；
Step 7, to the cavity sealant pouring and sealing of heater welding bushing 5, first heater is welded with J168 epoxide-resin glue
The cavity bottom of bushing 5 rises and 2/3 is fixed, seals, then with 704 silicon rubber to heater weld the cavity port of bushing 5 into
Row sealing；
Step 8, heater capillary 7 and welding bushing 8 is drawn to be welded with high temperature soldering.
In the actual operation process, fixed simultaneously in order to further enhance the insulating reliability between heater strip and shell
The heater strip of heater, facilitates subsequent operation, and there are also ceramic insulation bushing pipe 6 is installed on heater welding lining after step 6
Step in the cavity of set 5.
Sheathed heater is encapsulated by the method for step 1 to step 8, sheathed heater contact resistance is small, good insulation preformance,
Qualification rate is high, and after through a long time storage or use, insulation performance will not be reduced.
In batch production process of icing detector, icing is greatly improved using the packaging method of such sheathed heater
The qualification rate and functional reliability of detector.
