A magnetic piece 94 that can change position with 9 deformation of elastic reset component is provided with elastic reset component 9.Specifically, elastic reset
The bottom of component 9 is to push post portion 93, and top is an annular shape for surrounding and being fixedly connected on 93 top peripheral wall of pushing post portion
Become film 92, annular 92 top of deformation film is pressed on 1 top side inwall of housing.Push the also fixation of 93 peripheral part of post portion to be arranged with
One hard adapter sleeve 90, hard engagement sleeves 90 adopt material be easy to process, corrosion-resistant and deformation duroplastss, and with pushing
Post portion 93 is fixed thereon using tight fit mode, is moved with it and is moved, and is pushed post portion 93 and is fixed by hard adapter sleeve 90
It is connected to the middle part of movable contact flat 4.Annular deformation film 92 and above-mentioned pushing post portion 93 are made of the soft silica gel materials of identical, ring
Shape deformation film 92 and pushing post portion 93 are connected as a single entity, and using the elastic reset component 9 of such one, mix hard engagement sleeves
90, although manufacturing cost is slightly higher, but ruggedness is fine.Magnetic piece 94 is fixed in pushing post portion 93；93 bottom of pushing post portion
It is fixed on the middle part of movable contact flat 4.And an induction pieces 10 on 1 top side outer wall of housing, are further fixed on, it is provided with and magnetic in induction pieces 10
The corresponding inductive circuit board 100 in position of block 94, leaves between inductive circuit board 100 and magnetic piece 94 with 9 shape of elastic reset component
Change state and the sensing spacing that changes.
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 so as to which work is more stable, misoperation is reduced, and the annular deformation film 92 of the present invention is provided with two balances and leads to
Hole 920, so, the space that annular deformation film 92 and 8 inwall of upper lid are surrounded is not just confined space, is easy to counterbalance annular shape
Become 92 inner air and outer air pressure of film so that push post portion 93 and 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 is just increased, and under how many pressure values
Deformation just becomes unstable, so easily makes annular deformation film 92 contact blunt or misoperation, causes fine motion inductive switch needs
Bigger strength carrys out trigger switch, and stability is bad；Meanwhile, if not balancing through hole 920, even if each in annular deformation film 92
Also the top edge of 8 inwall contact position of annular deformation film 92 and upper lid is easily promoted to be raised and air-out during deformation, so as to cause
Make annular 92 deformation of deformation film irregular, which is easily caused 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 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 post portion.
Above-mentioned movable contact flat 4 is temperature-sensitive memory metal sheet, and movable contact flat 4 is provided with the bending contraction section 41 of a protuberance, should
With certain elasticity when bending contraction section 41 is flat, it is not delivered under the situation of pressure briquetting 5 is touched, activity can be ordered about
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 two ends of the first pin 2 and the second pin, movable contact flat 4 is overheated soon, now activity
Contact 4 deforms, especially 41 rapid desufflation of bending contraction section, and now, the first pin 2 and 4 fixing end of movable contact flat be not in clamping
Contact, or even between the movable contact 42 of movable contact flat 4 and the stationary contact 32 of the second grafting, also position does not correspond to, and cuts off the electricity of the two
Connection.
During use, when the housing 1 of fine motion inductive switch is fixedly connected with sensor, the trigger unit on sensor is to touching
Briquetting 5 applies downward pressure, touches briquetting 5 downwards, by the leverage of connecting rod 7, makes on the free end of movable contact flat 4
Raise, elastic reset component 9 is compressed, and annular 92 deformation as shown in Figure 7 of deformation film, while 42 He of movable contact of movable contact flat 4
Stationary contact 32 is contacted, and then connects first pin 2 and the second pin 3 at two ends, and fine motion inductive switch is 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,
Order about movable contact flat 4 and push 7 lower end of connecting rod so that touch briquetting 5 return and keep movable contact flat 4 laterally to balance, movable contact flat 4 with
Do not contact 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 stable.When the voltage overload at 3 two ends of the first pin 2 and the second pin, movable contact flat 4 is produced and is risen
Temperature, the 4 bending contraction section 41 of movable contact flat that temperature-sensitive memory metal makes are shunk, and bent downward deformation, so that its
Depart from 31 disconnecting circuit of transverse fold portion, so as to realize overcurrent protection of the fine motion inductive switch to sensor.
Above-mentioned connecting rod 7 is insulated connecting rod, and it is also all insulation that certain elastic reset component 9 is overall, in order to allow micro-
Dynamic inductive switch more safety and stability, prevents short circuit or overload protection failure.
Housing 1 below the free end of movable contact flat 4 is provided with tapped through hole 610, above-mentioned 3rd pin top 61
External screw thread is set, is threaded in tapped through hole 610 by the external screw thread, the upper end of the 3rd pin 6 and movable contact flat 4 from
By clearance for insulation is left between end or an insulating barrier 62 that can be the worse for wear is provided with.Under not enabled state, the upper end of the 3rd pin 6 is not
Stretch into the installation intracavity of housing 1, the i.e. upper end of the 3rd pin 6 to be located at below insulating barrier 62.Just stretch at the middle part of the 3rd pin 6
Go out on the outside of housing 1, foldable in the middle part of the 3rd pin 6,6 bottom of the 3rd pin is located at hull outside and may be folded on the housing 1
Bottom, 1 bottom of housing can arrange the groove of the 3rd pin bottom 60 of a receiving.
When enabling three pins, the 3rd pin 6 after threadingly through hole 1 rotates upwards, can wear out by the upper end of the 3rd pin 6
Insulating barrier 62, directly the free end conductive contact with movable contact flat 4.The present invention is as standby pin, necessity using the 3rd pin 6
When, the normally open or normally closed state of the fine motion inductive switch can reversely be switched.
Embodiments above is illustrated by way of example, and which can not be used as limitation of the present invention.Not
In the case of deviating from the scope of the invention, its principal character can be used for various embodiments.
