Abstract

The utility model relates to a super-thin flexible electrothermal core, which is composed of an electrothermal core with a thin membrane, a heat resistant protective thin membrane with single-sided glue, and a heat resistant heat insulating thin membrane with single-sided glue, wherein, the electrothermal core with thin membrane is composed of silver paste conductors and two power supplying silver paste disks which are silkscreened on heat resistant thin membrane, two conductive silver plated soldering lugs which are respectively stamped on the two silver paste disks and a power supply insulated conductor of two commercial power plugs (used for alternating current supply) [or with two core plugs (used for direct current supply) ], wherein, two multi-strand core wires arranged on the other end of the power supply insulated conducting wire are respectively welded on (or pressed in) the two conductive silver plated soldering lugs. The utility model has the advantages of favorable production process, reliable connection, thinness, softness and long service life and is particularly suitable for the heating and heat insulation occasions of nonplanar objects, such as electrothermal leather waistcoats, heat insulating lunch-boxes, heat insulating feeding bottles, heat insulating gloves, etc.

Description

Ultrathin flexible electric heating core

The utility model belongs to a kind of heating core, particularly belongs to the heating core of the flexible AC and DC power supply of a kind of ultrathin type.

Also used a kind of slim electrothermal piece in the commercially available electric warm clamp, but because employing is the metal electric heating silk, not only its flexibility is poor, poorer because of the manufacturability of its connection, or cause the junction to fracture easily, or the resistance variations heating of formation junction is concentrated and be easy to damage, thereby greatly reduce reliability, fail safe and the useful life of production and use.

The purpose of this utility model provides a kind of ultrathin type and the good heating core of softness, this heating core can make its heating with the AC and DC power supply, not only production technology is good, and be connected to each other also very reliable, thereby guaranteed reliability, fail safe and long-life of producing and using greatly.

The utility model is realized by following design: the silver of the resistance value suitable with heating object caloric value slurry lead L and two power silver-colored slurry dish P and Q on silk-screen on the heat-pesistant thin film M; At two silver-plated weld tabs A of conduction and B in the punching press respectively on two power supplies silver-colored slurry dish P and the Q; Two the multiply heart yearn C and the D of the other end of the power supply insulated conductor N of commercially available heading power plug E (being used for Alternating Current Power Supply) (or band two core plug F (being used for direct current supply)) then are welded in (or being pressed into) two silver-plated weld tabs A of conduction and B respectively, constitute film electric heating fuse of the present utility model thus; Single face glue heat-resisting protective film G sticks on this one side of heat-pesistant thin film M of silver slurry lead L; The heat-resisting thermal insulation film H of single face glue sticks on the another side of the heat-pesistant thin film M that does not have silver slurry lead L, constitutes the utility model thus.

Design of the present utility model is: be close to or be wrapped in heating object with heating core heat-resisting protective film G face, attaching plug E is inserted commercial power socket, heating core gets the heating of electric back, and the heating object temperature is risen; Or after two core plug F being inserted the accessory power outlet of combined integrated machine of rechargeable battery and time controller, heating core will be in time the interruption work of controller and heating synchronously with do not generate heat, thereby make the also synchronously rise and fall in tolerance of temperature of heating object, realize thus such as long-term power supply heat insulation work to electric warm clamp, incubation canteen, thermal insulation nursing bottle, moisture retentive glove etc.Finish invention task of the present utility model thus.
