It is logical.Specifically, the first pin 2 is as shown in figure 4,2 top of the first pin is the first furcation of Y-shaped structure, the first furcation
Including the symmetrical bifurcated plate 23 of pair of right and left, the activity passed through for connecting rod 7 is left between left bifurcated plate 23 and right bifurcated plate 23
Notch 22, i.e., movable notch 22 are located among the first furcation.Second pin, 3 upper end is equipped with the horizontal folding for being directed toward the first pin 2
Turn of bilge 31.Above-mentioned movable contact flat 4 laterally sets and between 3 top of 2 top of the first pin and the second pin, movable contact flat 4
Fixing end be connected to the top of the first pin 2, the free end of movable contact flat 4 is arranged on the lower section in transverse fold portion 31.Specifically,
4 fixing end of movable contact flat is equipped with the second furcation of Y-shaped structure, and the second furcation also includes the symmetrical divergent ends of pair of right and left
Son 45, the free gap 44 passed through for connecting rod 7 is also left between left and right bifurcated terminals 45, i.e., free gap 44 is positioned at second point
Among fork.
Arc gap groove 21 is equipped with the top of first pin 2, that is, left and right bifurcated plate 23,4 fixing end of movable contact flat is left and right
The end of bifurcated terminals 45 is arc-shaped, and left and right bifurcated terminals 45 correspond to the arc gap groove 21 for being caught in left and right bifurcated plate 23 respectively
It is interior.4 free end of movable contact flat is equipped with movable contact 42, and 31 bottom surface of transverse fold portion is equipped with the stationary contact coordinated with movable contact 42
32。
Above-mentioned 7 outer end of connecting rod, which is hinged on, touches on briquetting 5, and the inner side of housing 1 is equipped with hinged pillar 11, and the middle part of connecting rod 7 is hinged
Hinged pillar 11 in housing 1,7 the inner of connecting rod are stretched into the lower section of movable contact flat 4 and are connected with movable contact flat 4,
And the horizontal level of 7 middle part hinged place of connecting rod is higher than the horizontal level of movable contact flat 4,7 middle part hinged place of connecting rod is made
For fulcrum, using lever principle, when pushing shake-up briquetting 5, movable contact 42 connects stationary contact 32, switch closure.
Above-mentioned 9 upper end of elastic reset component is connected on 1 top side inner wall of housing, and lower end is fixed on the middle part of movable contact flat 4.
Specifically, the lower part of elastic reset component 9 is to push column portion 93, and top is one to surround and be fixedly connected on and push the top of column portion 93
The annular deformation film 92 of periphery wall, annular 92 top edge of deformation film are pressed on 1 top side inner wall of housing.Push 93 periphery of column portion
Portion's also fixing sleeve is equipped with a hard connector sleeve 90, and the material that hard connector sleeve 90 uses is easy to process, corrosion-resistant and deformation
Duroplasts, and be fixed thereon with pushing column portion 93 using tight fit mode, move with it and move, push column portion 93 by hard
Matter connector sleeve 90 is fixedly connected on the middle part of movable contact flat 4.Annular deformation film 92 and above-mentioned pushing column portion 93 are identical soft
Silica gel material is made, and annular deformation film 92 and pushing column portion 93 are connected as a single entity, using so integral elastic reset component
9, hard connector sleeve 90 is mixed, although manufacture cost is slightly higher, durability is fine.
Above-mentioned annular deformation film 92 is surrounded by the directed inclined upwardly arc-shaped concave of inner recess.In order to preferably make annular deformation
92 elastic deformation of film, makes its work more stablize, and malfunction reduces, and it is logical that annular deformation film 92 of the invention is equipped with two balances
Hole 920, so, the space that annular deformation film 92 and 8 inner wall of upper cover surround is not just confined space, easy to counterbalance annular shape
Become 92 inner air and outer air pressure of film so that pushing column portion 93 can more easily rise and drive annular 92 deformation of deformation film.
If not balancing through hole 920, first, the difficulty of annular 92 deformation of deformation film just increases, and under how many pressure value
Deformation just becomes unstable, annular deformation film 92 is contacted blunt or malfunction, causes fine motion inductive switch needs
The strength of bigger carrys out trigger switch, and stability is bad；Meanwhile if not balancing through hole 920, it is each even in annular deformation film 92
Also the top edge of 8 inner wall contact position of annular deformation film 92 and upper cover is easily promoted to be raised and discharge air during deformation, so as to cause
Make annular 92 deformation of deformation film irregular, it is be easy to cause after multiple deformation cooperation is distorted on housing 1.In order to preferably make ring
92 deformation of shape deformation film, two of the quantity symmetrical setting preferably as described above of balance through hole 920, i.e., two balance through holes
920 position office is on the annular deformation film 92 for pushing 93 both sides of column portion.
Above-mentioned movable contact flat 4 is temperature-sensitive memory metal sheet, and movable contact flat 4 is equipped with the bending contraction section 41 of a protuberance, should
With certain elasticity when bending contraction section 41 is flat, in the case where touching briquetting 5 and not being delivered to the situation of pressure, activity can be driven
The movable contact 42 of contact 4 departs from downwards stationary contact 32.The material of movable contact flat 4 is temperature-sensitive memory metal, and also has bending
Contraction section 41, when the current overload at 3 both ends of the first pin 2 and the second pin, movable contact flat 4 overheats soon, movable at this time
Contact 4 deforms, especially 41 rapid desufflation of bending contraction section, and at this time, the first pin 2 and 4 fixing end of movable contact flat be not clamped
Contact, in addition movable contact flat 4 42 and second grafting of movable contact stationary contact 32 between also position do not correspond to, cut off the electricity of the two
Connection.
In use, when the housing 1 of microswitch is fixedly connected with sensor, the trigger unit on sensor is to touching briquetting
5 apply downward pressure, touch briquetting 5 downwards, by the leverage of connecting rod 7, the free end of movable contact flat 4 is raised up, bullet
Property reset assembly 9 compressed, and annular 92 deformation as shown in Figure 7 of deformation film, while the movable contact 42 and stationary contact of movable contact flat 4
32 contacts, and then first pin 2 at connection both ends and the second pin 3, fine motion inductive switch are switched on；
Movable contact flat 4 under normality is restored to the original state by elastic reset component 9, i.e., annular deformation film 92 extends to original state,
Drive movable contact flat 4 to push connecting rod 7 lower end so that touch 5 return of briquetting and keep the laterally balance of movable contact flat 4, movable contact flat 4 with
Do not contacted between transverse fold portion 31, such structure setting, it is therefore intended that so that fine motion induction switch structure is simple, reaction spirit
It is quick, above all using stablize.When the voltage overload at 3 both ends of the first pin 2 and the second pin, movable contact flat 4, which produces, rises
Temperature, the 4 bending contraction section 41 of movable contact flat that temperature-sensitive memory metal makes are shunk, and bent downward deforms, so that its
Depart from 31 disconnecting circuit of transverse fold portion, so as to fulfill overcurrent protection of the microswitch to sensor.
Above-mentioned connecting rod 7 is insulated connecting rod, and overall certain elastic reset component 9 is also all insulation, in order to is allowed micro-
Dynamic inductive switch more safety and stability, prevents short circuit or overload protection failure.
Embodiments above is illustrated by way of example, it can not be used as limitation of the present invention.Not
In the case of deviating from the scope of the invention, its main feature can be used for various embodiments.
