Fig. 5,6,7 are the structural schematic diagrams before the utility model improves.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment
The electronic heater for electronic thermoregulator as shown in Fig. 1,3,4, including sheath 5 and ceramic tube 8, in about 5 sheath
Sky, sealed bottom connect cold extrusion end socket, and with argon arc welding process repair welding, so that stronger and sealing, thoroughly nothing is sealed in guarantee
Gas leak phenomenon, lower part is provided with ceramic tube 8 in sheath 5, and 8 length of ceramic tube is shorter than in the past, and 8 outer wall of ceramic tube winds heating wire 9,
Two adjacent hole a7 and hole b10 are equipped in ceramic tube 8 from top to bottom, adjacent holes setting is used for code wire, and the hole bottom a is can
With what is led to, wire stylet 1 does not pass to bottom, the perforation of the hole bottom b10, and wire stylet 1 is stretched out from the hole bottom b10, and hole a7 and hole b10 are all provided with
There is wire stylet 1, it is pad at the b10 outlet at bottom of hole that it is pad at the a7 top exit of hole that wire stylet 1, which is single pure nickel wire,
Pad is that wire stylet 1 and heating wire 9 are welded by winding carry out face and face, that is, wire stylet 1 and heating wire 9 will be by that will send out
Heated filament 9 is closely wound to face is carried out on wire stylet 1 and face is welded, and it is meticulous (0.15mm) to change originally soldered material, is caused
Product jointing success rate is too low, and product is unable to reach batch production purpose, heating wire 9 big with the spacing of silk, is effectively prevented
Silk causes partial short-circuit with mutually touching for silk, and wire stylet 1 is arranged at 2 center of conducting wire, that is, the outer surface cover of wire stylet 1 is to lead
Line 2, conducting wire 2 are Teflon material, Teflon alias: polytetrafluoroethylene (PTFE) (Poly tetra fluoroethylene, letter
Be written as PTFE), present integrated wire, present wire stylet and conducting wire wall be it is integrated, product is more firm, high temperature resistant and insulation effect
Fruit is more preferable, and ceramic tube 8 and conducting wire 2 are located at center, and insulant 6, sheath 5 are equipped between ceramic tube 8 and conducting wire 2 and sheath 5
External wall of upper portion is equipped with lid 4, and lid 4 is incorporated 5 specified position of sheath, and the particular location point for needing to press can be set by tooling, oblique
Surrounding extruding is carried out to locating slot, locating slot inside length is greater than length of outer side, is fixed on lid 4 on sheath 5, lid 4 and sheath 5
Cooperated using pine with mode, after product is fixed by tooling, is squeezed lid 4 to sheath with skew force, product advantage is
Parts machining required precision reduces, and processing cost reduces；It is smaller to product product external force when assembling product, guard head (peace
Holding position), any deformation will not be generated, qualification rate is promoted, and working efficiency is promoted, so that product cost is reduced, such as Fig. 5 before improving
Shown, original structure fit system is press-fitted using interference, requires excessively high, processing precision of products requirement height since magnitude of interference cooperates, and zero
It is high that component produces finished product, disadvantage: 1. even up to zero match zero when magnitude of interference is too small, and product has the risk of cooperation incessantly；2. working as
Guard head deformation dimension overproof, which can not be installed, when product magnitude of interference is too big, after product press-fitting leads to scrap of the product, and the two is different
The direction of extrusion it is as shown by arrows, the application oblique and horizontal power is power downwardly and horizontally before improvement, in 5 top of sheath
It is equipped with sealant 3 between wall and conducting wire 2, sealant 3 is equipped between conducting wire 2 and conducting wire 2, conducting wire is stretched out from sealant 3, is sealed
Glue thickness is more than 3mm, seals up insulant 6, promotes effect, as shown in fig. 6, sheath and lid integral type, as shown in fig. 7, in the past
Metal shell pipe and upper set integral type, difficulty of processing is obviously all bigger, the round steel of materials diameter 12mm long 24mm, outer diameter
The hollow pipe of 4mm internal diameter 3mm long 100mm, conventionally employed diameter 12mm long 100mm round steel, 6 times more than this product materials, in addition
Tradition needs multiple vehicle outer diameter and repeatedly drilling, and concentricity is difficult to control, and this product uses cold extrusion packet header technology, without drilling,
It closes and is riveted into one with lid, not only simple process and quality is guaranteed, be not integrally formed, but be entirely capable of reaching after riveting and set
Required pressure is counted, processing cost is decreased obviously.
As shown in Fig. 2, being handled on the outside of the pad and heating wire by pre insulated, that is, wrapped up with insulant 6, warp
It is not easily to fall off to cross pre insulated processing insulant, then external setting insulant 6, two layers of insulation, safety is good, and insulant 6 is patent
High temperature insulating material in number ZL2013107476175.
For the lid 4 in inverted T shaped, lid 4 is hollow, and recess is equipped with locating slot on 4 circular connector of lid, and positioning slot cross-section is in triangle
Shape, 4 external wall of upper portion of lid are recessed inwardly, and recess can apply external force, and the external force that is not recessed can not apply, and lid 4 is filled from 5 bottom of sheath
Into, after be directly placed into tooling, lid 4 can arrive the position preset, there is conducting wire 2 above, can compare difficult dress.
The method that 4 inner hole of lid uses remove materials obtains the upper limit value of roughness Ra as 0.8 μm, 4 bottom of lid
The method for using remove materials obtains the upper limit value of roughness Ra as 0.8 μm, and 5 outer diameter of sheath is using remove materials
The upper limit value that method obtains roughness Ra is 0.4 μm, so that more stable and effective when the riveting of product lid 4.
It being flushed at the top of 3 top of sealant and sheath 5, sealant 3 is exposing outside less, and it is few by oxidation, but be above
It can be used.
In use, 1 positive and negative anodes of wire stylet are first separately connected ceramic tube 8, wire stylet 1 provides control signal and powers on,
Operating path are as follows: power positive line → ceramic tube → insulant → heating wire → insulant → ceramic tube → power cathode line.
It should be understood that the above is only the preferred embodiment of the utility model only, it is not sufficient to limit this reality
It for those of ordinary skills, can basis within the spirit and principle of utility model with novel technical solution
Above description is increased and decreased, is replaced, converted or is improved, and all these increases and decreases, replacement, transformation or improved technical solution,
It all should belong to the protection scope of the appended claims for the utility model.
