Abstract
The utility model discloses a photoresistor, which is formed by a transparent protection layer, a photosensitive layer, a base and electrodes, wherein the upper end of the base is provided with an arc surface, the photosensitive layer is arranged on the upper end of the base and attached to the surface of the base, the photosensitive layer is connected with the electrodes, and the transparent protection layer is plated on the surface of the photosensitive layer. The photoresistor can effectively receive diverging light, thereby increasing the sensitivity of the photoresistor; and can effectively prevent the sensitivity from decreasing due to moisture or accumulated dust, through arranging the transparent protection layer.
Description
Technical field
The utility model relates to a kind of electronic component, particularly a kind of photo resistance.
Background technology
Photo resistance is very common a kind of electronic component; its resistance value changes according to the variation of illumination; according to its characteristic; through being usually used in making light-operated switch; common photo resistance remains to be increased for the susceptibility of diverging light; and photo resistance tends to because photosensitive layer makes moist or dust accretions and cause the reduction in useful life; therefore; the utility model provides a kind of photo resistance can effectively receive divergent rays; thereby improved the sensitivity of photo resistance; and by protective clear layer is set, can effectively prevents the problem that photo resistance descends because of the sensitivity of making moist or the accumulation of dust causes, thereby increase useful life.
The utility model content
The purpose of this utility model is, provides a kind of photo resistance can effectively receive divergent rays, thereby has improved the sensitivity of photo resistance, and can effectively prevent the problem that photo resistance descends because of the sensitivity of making moist or the accumulation of dust causes.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of photo resistance is characterized in that, comprises protective clear layer, photosensitive layer, pedestal and electrode, curved of described pedestal upper end, and photosensitive layer is located at the pedestal upper end and is fitted with base-plates surface, the photosensitive layer connecting electrode, described protective clear layer is plated on the photosensitive layer surface.
The manufacturing material of the photosensitive layer of a kind of photo resistance that the utility model provides can be sulfide, selenides, tellurides of metal etc.
Description of drawings
Fig. 1 is the structural representation of a kind of photo resistance of the utility model one execution mode.
Number in the figure: 1, protective clear layer; 2, photosensitive layer; 3, pedestal; 4, right lead-in wire; 5, left lead-in wire.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1; a kind of photo resistance; comprise protective clear layer 1, photosensitive layer 2, pedestal 3 and electrode; curved of described pedestal 3 upper ends; photosensitive layer 2 is located at pedestal 3 upper ends and fit in pedestal 3 surfaces; photosensitive layer 2 connecting electrodes, electrode is drawn by left lead-in wire 5 and right lead-in wire 4, and described protective clear layer 1 is plated on photosensitive layer 2 surfaces.
To sum up; a kind of photo resistance that the utility model provides is by the arcwall face design of its pedestal; can effectively receive divergent rays; thereby improved the sensitivity of this photo resistance; and by protective clear layer is set, both photosensitive layer was protected, do not affected again the reception of light; thereby effectively prevent the problem that photo resistance descends because of the sensitivity of making moist or the accumulation of dust causes, and increased useful life.
Above-described only is execution mode of the present utility model, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, and these all belong to protection range of the present utility model.
