Abstract
The utility model discloses a photoelectric switch with radiating slots. The photoelectric switch with the radiating slots comprises a shell, an optical transmitter and an optical receiver are arranged in the shell, an optical window for light of the optical transmitter to be emergent is arranged on the shell, and the radiating slots communicated with an inner cavity of the shell are arranged on the shell. The photoelectric switch with the radiating slots has the advantages that heat generated in operation of the optical transmitter and the optical receiver which are in the shell can be effectively transferred to an external environment by the aid of the radiating slots, so that operational stability of electronic components is guaranteed.
Description
Technical field
The utility model relates to a kind of optoelectronic switch that has the slotted eye that dispels the heat.
Background technology
Optoelectronic switch (photoelectric sensor) is the abbreviation of photoelectricity near switch, it is to utilize detected material to the blocking or reflect of light beam, and by the synchronization loop gating circuit, thereby inspected object has or not.Optoelectronic switch converts input current into light signal and penetrates on reflector, receiver is again according to the strong and weak of the light that receives or there is unmatchful target object to survey.
The structure of existing optoelectronic switch generally comprises the shell optical transmitting set interior with being arranged at shell, optical receiver etc.Wherein optical transmitting set is generally light-emitting diode or laser diode, and optical receiver is generally photodiode or phototriode.Because optical transmitting set and optical receiver can produce great amount of heat when work, therefore, often make optoelectronic switch when long-time the use, temperature is too high in the shell, has influenced the stability of electronic component work such as optical transmitting set and optical receiver.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that prior art exists, and the optoelectronic switch that dispels the heat slotted eye having of a kind of reasonable in design, good stability is provided.
For realizing above-mentioned purpose; The technical scheme of the utility model is to include shell; Be provided with optical transmitting set and optical receiver in the described shell, described shell is provided with the optical window of the light outgoing that supplies optical transmitting set, and described shell is provided with the heat radiation slotted eye that communicates with shell inner cavity.
Further being provided with is that described optical transmitting set is light-emitting diode or laser diode.
Further being provided with is that described optical receiver is photodiode or phototriode.
The utility model has the advantages that utilize the heat radiation slotted eye can be effectively with the heat transferred of optical transmitting set in the shell and optical receiver work generation in external environment condition, ensured the stability of each electronic component work.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation.
Embodiment
Through embodiment the utility model is carried out concrete description below; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection range, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned utility model.
The embodiment of the utility model as shown in Figure 1; Include shell 1, be provided with optical transmitting set and optical receiver in the described shell 1, the described optical transmitting set of present embodiment is light-emitting diode or laser diode; Described optical receiver is photodiode or phototriode; In addition, described shell 1 is provided with the optical window 11 of the light outgoing that supplies optical transmitting set, and described shell 1 is provided with the heat radiation slotted eye 12 that communicates with shell inner cavity.
