Description
Technical field
The utility model belongs to electric heater unit field, and in particular to a kind of plug-type three proofings electrothermal tube.
Background technology
Electrothermal tube is a kind of electric elements for converting electrical energy into heat energy, and it is widely used in firing equipment, such as electricity
Hot pot, insulating pot etc., traditional electrothermal tube manufacture craft are as follows:Load heating wire in Can, then in heating wire week
Enclose and fill and be compacted the higher Insulation stopping of good insulation preformance, thermal conductivity factor, stem is provided with the port of shell, tradition
Stem top be threaded post, in order to prevent stem from contacting electric leakage with Can, generally at the port of Can
One ceramics seat is set, is then compressed with nut, then lug plate, nut, lug plate is installed successively above nut again
It is connected with wire.Following drawback be present in the electrothermal tube of said structure：
1) ceramics seat is frangible, in its compaction process, will be very easy to that ceramics seat is caused to damage using nut, once
Ceramics seat crushes during use, then Can there is the risk of electric leakage, and after ceramics seat damage, water or vapor are easy
Enter inside Can from broken, Insulation stopping can expand after absorbing moisture, the risk of booster be present.
2) parts more (1 ceramics seat, two nuts, 1 lug plate) of the whole installation process needs of stem, operation
Cumbersome, this not only adds cost, also reduces production efficiency.
Utility model content
The purpose of this utility model is safety be present due to fault of construction at its stem of solution prior art electrothermal tube
The defects of poor performance, cost are high, low production efficiency, there is provided a kind of plug-type three proofings electrothermal tube, it is using high temperature casting glue to gold
The port of category shell is sealed, and stem front end is arranged into plug-type structure, cost is reduced, improves production efficiency,
Waterproof, anticreep, explosion stack performance is good.
The utility model is achieved by the following technical solution；
I.e. a kind of plug-type three proofings electrothermal tube, including Can, stem, its feature are provided with the port of Can
It is to be provided with embedding Capsule at the port of Can, the top of stem is plug.
It is connected in order to facilitate stem with heating wire, the bottom of stem is threaded post.Heating wire winding in threaded post,
It is connected firmly, is easy to operate.
The shape of electric heating shell of the present utility model can be the shape of any electrothermal tube known in the art, example
Such as but it is not limited to strip, annular, butterfly, spiral shape.
Embedding Capsule of the present utility model is formed using resistant to elevated temperatures casting glue cast solidify afterwards, and casting glue is prior art
Commercially available matured product, casting glue can play waterproof and dampproof, dust-proof, insulation, anticorrosion, high temperature resistant, shockproof after being fully cured
Effect.
It is 15mm that embedding Capsule of the present utility model, which is preferably but not limited to thickness,.
Stem upper end of the present utility model is plug-like, and it can use any of plug shape of prior art,
Such as, but not limited to flat sheet-like, cylindric, triangle is bar-shaped etc..
As a preferred scheme of the present utility model：The top of stem is flat sheet-like structure, the side of stem
Provided with spacing preiection.
Flat sheet-like plug of the present utility model matches with the matching used wire socket of applicant, is set on wire socket
The spacing hole matched with spacing preiection, spacing preiection is located just in spacing hole after plug inserts wire socket, can be to plug
Play a part of connection fastening with wire socket.
When plug uses other shapes, whether can be connected firmly, decide whether according between plug and wire socket
Spacing preiection is set.
The utility model has the advantages of rational in infrastructure, cost is low, flexible and convenient to use, production efficiency is high.This practicality is new
Type instead of ceramics seat and nut structure, stem top is using slotting relative to traditional electrothermal tube using high temperature embedding Capsule
Header structure, lug plate and nut structure are simplified, greatly reduce the cost of product, simplify installation steps, improve production
Efficiency.
