Background technology
By NTC temperature-sensitive chip as core component, the temperature sensor of taking different packing forms to form has been widely used in various temperature sensings, temperature compensation, temperature-control circuit, and it plays the central role that the variable of temperature is changed into required electronic signal in circuit.
The features such as the temperature sensor of new structure is fast by detecting temperature, detection accuracy is high, fitted position is little, are applicable to being arranged on Worn type human body and inquire after on instrument.
As shown in Figure 1 and Figure 2, the method for making of at present conventional NTC temperature sensor is: NTC temperature-sensitive chip 1 ' is attached on fixing metal sheet 2 ', recharge epoxy resin 3 ' NTC thermistor 1 ' and fixing metal sheet 2 ' are combined, reach the object of being convenient to be arranged on equipment and instrument.But the temperature sensor that the prior art is manufactured is because its filler is more, can cause its thermal capacity large, and NTC temperature-sensitive chip 1 ' has completely cut off it and has contacted with the direct of fixing metal sheet 2 ' after epoxy resin 3 ' encapsulation, cause its temperature-sensitive speed slow and be subject to the impact of filler large, be unfavorable for providing precision data fast and in the short time.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, concrete open a kind of novel quick response temperature sensor, the quick response temperature of this temperature sensor, temperature data comparatively was accurately provided in the short time, can meet urgent need provides the equipment of temperature parameter to use at short notice, practical.
In order to overcome above-mentioned technical purpose, the utility model is realized by following technical scheme:
The novel quick response temperature sensor of one described in the utility model, comprise NTC temperature-sensitive chip and fixing metal sheet, the first surface electrode of described NTC temperature-sensitive chip is placed in fixing metal sheet bottom interior surface accordingly, on described fixing metal sheet, is welded with the first lead-in wire; On second electrode of described NTC temperature-sensitive chip, be welded with the second lead-in wire, and have one deck epoxy resin protective seam corresponding to the surface coverage of this second surface electrode.
As the further improvement of above-mentioned technology, the first surface electrode of described NTC temperature-sensitive chip is attached to NTC temperature-sensitive chip on fixing metal sheet by conductive silver paste.
As the further improvement of above-mentioned technology, described fixing metal sheet is dish shape sheet metal.
In the utility model, the outside surface of the bottom of described fixing metal sheet is coated with insulating coating.
In the utility model, described the first lead-in wire or the second lead-in wire are enameled wire.
Compared with prior art, the beneficial effects of the utility model are:
(1) temperature sensor described in the utility model, due to NTC temperature-sensitive chip first surface electrode is attached on fixing metal sheet completely, improves its temperature-sensitive speed widely;
(2) in the utility model, because the filling material quantity as epoxy resin protective seam reduces, can make its thermal capacity reduce, therefore can significantly reduce the impact of filling material on chip;
(3) in the utility model, the lead-in wire being welded on NTC temperature-sensitive chip can be used as an electrode, and in addition, the each position on whole fixing metal sheet can become electrode, has so just improved the assembling capacity of whole sensor, easy installation and reliable;
(4) in the utility model, the effect of ultra-thin insulating coating is to play to avoid temperature sensor short circuit and dielectric voltage withstand is bad etc. that situation occurs, and security performance improves greatly;
(5) quick response temperature sensor described in the utility model, can meet urgent need provides the equipment of temperature parameter as medical-therapeutic treatment of human body temperature detection instrument at short notice, and the use of wearable type body temperature monitoring instrument etc. is practical.
