Description
Technical field
The utility model relates to thick-film heating elements, and in particular to integral type thick-film heating element terminal box.
Background technique
Stainless steel thick film heating body is from inside to outside mainly by stainless steel base, interior insulation dielectric layer, conductor layer, resistance heating
Layer and external insulation dielectric layer composition, water flow flows through from stainless steel inner wall, and wherein interior insulation thickness of dielectric layers is in 100 microns,
Since the heat transfer from resistant heat generating layer to stainless steel base is apart from short, so thermal resistance very little, thermal response speed are fast.
Thick-film heating belongs to face heating, is integrally heated relatively uniform, will not make because heater surfaces generate a large amount of bubbles
Heating efficiency reduces.Since heat can conduct away in time, so entire heat-generating pipe surface temperature is not high, open fire will not be caused.
Safety is good, long service life.Since big multi-temperature is higher at work for thick-film heating element, cause its supply terminals and electricity
The soldering of source wire terminal junction is easy to melting softening, and being pullled external force by power supply line due to power cord connector is influenced to be easy to take off
From heating element supply terminals, thick-film heating element cisco unity malfunction is caused.
Applicant is in application on February 24th, 2017 " a kind of novel thick film heating device, the thick-film heating including tubulose
Element and shell, the thick-film heating element are placed in the shell, are equipped between the thick-film heating element and shell
Elastic conductor piece, elastic conductor piece one end is fixed on the housing, and the other end of the elastic conductor piece is suppressed in institute
It states on the supply terminals of thick-film heating element, while being aided with soldering；Pass through the wiring of elastic conductor piece and thick-film heating element
End is electrically connected, the scolding tin in thick-film heating element hot operation, between elastic conductor piece and thick-film heating element terminals
It is not easily to fall off melting softening；Even if falling off, due to the resilient property of elastic conductor piece, make elastic conductor piece still with
The terminal contact of thick-film heating element and electric connection guarantee the duration and stability of thick-film heating element power supply."
A period of time after applicant introduces the said goods to the market, client feedback following problems: 1. are filled more due to this product
On water heater or coffee machine, above structure is exposed dangerous outside；2. subsequent production installation is inconvenient, though 3. aforementioned patents
Terminals are so improved, but still need original mode to carry out individually welding operation the terminals of ground wire, therefore fill
It also needs individually to handle ground wire after setting installation, and is routed in disorder when above-mentioned apparatus use, be unfavorable for later maintenance.In addition, due to
The process for needing to weld, therefore production cost is also higher when we produces.
Utility model content
