Abstract
The utility model discloses a normally open type photoelectric inductive switch which comprises a U-shaped support; a transmitter is arranged at one end of the support; a receiver is arranged at the other end of the support; a baffle is arranged between the transmitter and the receiver and is connected with a key-press panel; a small hole is arranged on the baffle; and when a position is reset, an optical signal transmitted by the transmitter passes through the small hole to be received by the receiver. The normally open type photoelectric inductive switch makes up the defects of short service life and low sensitivity existing in the traditional mechanical switch, converts the optical signal into an electric signal to control the break-make of circuits and avoids the mechanical movement of the mechanical switch, thereby achieving the purpose of prolonging the service life and increasing the sensitivity.
Description
Technical field
The utility model relates to a kind of switch, specifically a kind of photoelectric sensor switch open in usual.
Background technology
At present, various device or device are gone up the logic switch that is used to control mains switch that uses, and what use basically all is mechanical switch.Through pressing mechanical switch, produce logic level signal, the functional module in trigger equipment or the device realizes function corresponding.But mechanical switch comes down to a kind of contact switch, has contact resistance, can produce friction between the mechanical switch contact simultaneously, make that its mechanical endurance is shorter, and sensitivity is relatively poor; Mechanical switch is easy to make moist, thereby influences the operate as normal of equipment or device.
The utility model content
The purpose of the utility model provides a kind of simple in structure, precise control, the photoelectric sensor switch of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of photoelectric sensor switch open in usual comprises support, and said support is the U type; Support one end is provided with reflector, and the other end corresponding with it is provided with corresponding receiver, between reflector and receiver, is provided with baffle plate; Baffle plate is connected with keypad; Baffle plate is provided with an aperture, and when reset position, the light signal of reflector emission passes aperture and is received by the receiver.
Said receiver is NPN type phototriode or the photosensitive triode of positive-negative-positive.
Said baffle plate is that light tight material is processed.
The two ends of keypad are connected with support through spring, and when keypad was under pressure, the aperture position on the baffle plate was moved; Baffle plate stops the light signal that reflector sends; Receiver is given control circuit with feedback information, thus the control circuit break-make, and make circuit be in normally open.
The beneficial effect of the utility model is:
It is short that the utility model has remedied the existing machinery switch life, and the defective that sensitivity is low is transformed into the signal of telecommunication with light signal and comes the control circuit break-make, has avoided the mechanical movement of mechanical switch, thereby reaches the purpose that increases the service life, improves sensitivity.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the reset mode of the utility model;
Structural representation when Fig. 2 is under pressure for the utility model keypad.
Embodiment
A kind of photoelectric sensor switch open in usual comprises support 6, and said support is the U type; Support 6 one ends are provided with reflector 2, and the other end corresponding with it is provided with corresponding receiver 5, between reflector 2 and receiver 5, are provided with baffle plate 7; Baffle plate 7 is connected with keypad 4; Baffle plate 7 is provided with an aperture 8, and when reset position, the light signal of reflector 2 emissions passes aperture 8 and is received device 5 and receives.
Said receiver 5 is NPN type phototriode or the photosensitive triode of positive-negative-positive.
Said baffle plate 7 is processed for light tight material.
The two ends of keypad 4 are connected with support 6 through spring 3, and when keypad 4 was under pressure, aperture 8 positions on the baffle plate were moved; Baffle plate stops the light signal that reflector 2 sends; Receiver 5 is given control circuit 1 with feedback information, thus the control circuit break-make, and make circuit be in normally open.
More than the disclosed specific embodiment that is merely this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be regarded as belonging to the utility model protection range.
