Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
Extremely shown in Figure 5 like Fig. 1, a kind of electronic type sensitive switch, it comprises housing, pressing key 3, mechanical reed 9, reed mount pad 10, light-emitting component 4, light-sensitive element 5.Housing comprises upper casing 1 and lower casing 2, and upper casing 1 is fixed with lower casing 2 snappings.
Light-emitting component 4, light-sensitive element 5 all are fixedly mounted in the housing, and the electrical pin 51 of the electrical pin 41 of light-emitting component 4, light-sensitive element 5 all stretches out outside the housing, and the optical receiving end 52 of light-sensitive element 5 is positioned on the light emitting path 100 of light transmitting terminal 42 of light-emitting component 4.Reed mount pad 10 also is fixedly mounted in the housing, and mechanical reed 9 is installed on the reed mount pad 10, and an end of mechanical reed 9 is extended with catch 93.The top of pressing key 3 is positioned at outside the housing, and the bottom of pressing key 3 is positioned at housing.Concrete, pressing key 3 is installed in upper casing 1, and light-emitting component 4, light-sensitive element 5, reed mount pad 10 are installed in lower casing 2.
As preferred construction, reed mount pad 10 is provided with fixed part 101, normally closed 102 and support portion 103, and fixed part 101, normally closed 102 and support portion 103 from left to right are arranged in order; Mechanical reed 9 is provided with installation portion 91, energy storage part 92; Installation portion 91 is fixedly connected with fixed part 101; One end of energy storage part 92 is fixedly connected with mechanical reed 9, and the other end is fixedly connected with normally closed 102.First mounting panel 6, second mounting panel 7 have been extended upward on the lower casing 2; All offer light hole on first mounting panel 6, second mounting panel 7; The medial surface of the medial surface of first mounting panel 6 and second mounting panel 7 is placed relatively, and the center of circle of the center of circle of the light hole 61 of first mounting panel 6 and the light hole 71 of second mounting panel 7 is located along the same line; Light-emitting component 4 is installed on the lateral surface of first mounting panel 6; Light-sensitive element 5 is installed on the lateral surface of second mounting panel 7; And the position of light transmitting terminal 42 is corresponding with the position of the light hole 61 of first mounting panel 6, and the position of optical receiving end 52 is corresponding with the position of the light hole 71 of second mounting panel 7; Catch 93 is between the medial surface of the medial surface of first mounting panel 6 and second mounting panel 7.Further, the top of first mounting panel 6 and/or second mounting panel 7 is provided with hook portion 8.
Like Fig. 4 and shown in Figure 5; When pressing key 3 was positioned at primary importance with respect to housing, the bottom of pressing key 3 was positioned at the top of mechanical reed 9, and pressing key 3 does not produce pressure to mechanical reed 9; At this moment, catch 93 is on the light emitting path 100 between optical receiving end 52 and the light transmitting terminal 42.And, an end of mechanical reed 9 be positioned at support portion 103 the top and with hook portion 8 butts, the two ends of energy storage part 92 distance is a drift.That is to say that at this moment, light transmitting terminal 42 is stopped by catch 93 that through the light that light hole 61 sends optical receiving end 52 does not receive illumination, light-sensitive element 5 internal resistances are infinitely great, equal open circuit.
When pressing pressing key 3, when pressing key 3 is positioned at the second place with respect to housing, the bottom of pressing key 3 and mechanical reed 9 butts; 3 pairs of mechanical reed of pressing key 9 produce downward pressure, make mechanical reed 9 that deformation take place, and catch 93 moves down; Catch 93 moves on to the below of the light emitting path 100 between optical receiving end 52 and the light transmitting terminal 42, and at this moment, an end of mechanical reed 9 is positioned at the below of hook portion 8 and is supported on the support portion 103; The two ends distance of energy storage part 92 is less than drift, and energy storage part 92 is compressed.At this moment, the light that light transmitting terminal 42 sends arrives optical receiving end 52 through light hole 61, light hole 71, and after light-sensitive element 5 received illumination, internal resistance was minimum, is equivalent to path.
When unclamping hand; Because energy storage part 92 discharges elastic potential energy, and mechanical reed 9 is set back, catch 93 is again on the light emitting path 100 between optical receiving end 52 and the light transmitting terminal 42; Pressing key 3 is also got back to original position, and the electronic type sensitive switch comes back to open-circuit condition.
In the foregoing description, light transmitting terminal 42 can adopt light-emitting diode or laser diode; Optical receiving end 52 can adopt photodiode or phototriode.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
