Abstract
The utility model relates to the field of sensors, and in particular relates to a photoelectric sensor. The photoelectric sensor comprises a casing body, an anode and a cathode. The cathode comprises a photoelectric effect end which is shaped like a hemispherical casing, a cathode support section and a cathode pin section. The anode comprises an electronic receiving end, an anode support section and an anode pin section. The electronic receiving end is located above the photoelectric effect end. The distance between the photoelectric effect end and the electronic receiving end is less than the distance between the anode support section and the cathode support section. The photoelectric sensor can well detect lights of wide source directions.
Description
Technical field
The utility model relates to sensor field, especially a kind of photoelectric sensor.
Background technology
Under the irradiation of light, the electrons of Cucumber inside is out formed photoelectron by photon excitation, and this phenomenon is referred to as photoelectric effect by people.Use photoelectric effect principle just can produce photoelectric sensor.In prior art, photoelectric sensor often can only have the photoelectron that the light of a direction irradiates generation to be received well by anode, and the light source direction that photoelectric sensor can be surveyed has limitation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of photoelectric sensor, and this photoelectric sensor can be surveyed the wider light of source direction well.
The disclosed photoelectric sensor of the utility model comprises housing, anode and negative electrode, described negative electrode comprises photoelectric effect end, cathode support section and the negative electrode pin section of hemispherical Shell shape, described anode comprises electronics receiving terminal, anode-supported section and anode pin section, described electronics receiving terminal is positioned at photoelectric effect end top, and the distance between described photoelectric effect end and electronics receiving terminal is less than the distance between anode-supported section and cathode support section.
Preferably, described housing bottom is provided with support column, and described anode and negative electrode are through support column.
The beneficial effects of the utility model are: the photoelectric effect end of hemispherical Shell shape can absorb from top and light around and produce photoelectron, and is received well by anode, so this photoelectric sensor can be surveyed the wider light of source direction well.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Mark in figure: 1 is housing, 201 is electronics receiving terminal, and 202 is anode-supported section, and 203 is anode pin section, and 301 is photoelectric effect end, and 302 is cathode support section, and 303 is negative electrode pin section, and 4 is support column.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the disclosed photoelectric sensor of the utility model, comprise housing 1, anode and negative electrode, described negative electrode comprises photoelectric effect end 301, cathode support section 302 and the negative electrode pin section 303 of hemispherical Shell shape, described anode comprises electronics receiving terminal 201, anode-supported section 202 and anode pin section 203, described electronics receiving terminal 201 is positioned at photoelectric effect end 301 tops, and the distance between described photoelectric effect end 301 and electronics receiving terminal 201 is less than the distance between anode-supported section 202 and cathode support section 302.In the photoelectric sensor course of work, first, at anode, add positive voltage, at negative electrode, add negative voltage, when having the light of enough energy to irradiate, will there is photoelectric effect in the photoelectric effect end 301 of negative electrode, utilizing emitted light electronics, and under the electric field force effect that photoelectron produces in negative and positive the two poles of the earth voltage difference, the electronics receiving terminal 201 of anode moves, by electronics receiving terminal 201, absorbed, electric charge moves generation current, and so, photoelectric sensor has just converted illumination to current signal.The photoelectric effect end 301 of hemispherical Shell shape can receive from its top and light around and produce photoelectron, and is received well by anode, so this photoelectric sensor can be surveyed the wider light of source direction well.Distance between photoelectric effect end 301 and electronics receiving terminal 201 is less than the distance between anode-supported section and cathode support section, so, is conducive to electronics receiving terminal 201 and receives photoelectron.
In photoelectric sensor, if by housing 1 supporting anodes and negative electrode, can easily cause damage because housing is thinner, so as optimal way, described housing 1 bottom is provided with support column, described anode and negative electrode are through support column 4.With support column 4 support negative electrodes and anode, just can make photoelectric sensor more firm like this.
