Abstract
The invention discloses a pressing type elastic safety switch assembly comprising a housing and a switch button. The housing includes a first cavity and a second cavity. The switch button consists of a movable contact, a holding sleeve, an elastic element, a pressing part and a silica-gel bowl. The silica-gel bowl includes a funnel opening part, a base part, an accommodation cavity and mouth parts. When the pressing part is not extruded by any external force, the elastic element applies a pulling force on the silica-gel bowl to drag the funnel opening part; the mouth parts are extruded to enter the holding sleeve; the mouth parts extrude each other and seal the accommodation cavity, so that the first cavity and the accommodation cavity are separated completely and a first wiring terminal is enclosed, so that entrance of moisture into the first cavity is prevented effectively. The first wiring terminal and a second wiring terminal are in a complete breaking state, so that a waterproof effect is realized and aging due to moisture can be avoided; and thus the security of the assembly is high.

In connected state.
As shown in figure 1, when pressing splenium 33 no longer stress, under the reset response of spring restoring force, to outside housing
Side will be pressed splenium 33 and be ejected, and quarrel portion 30b pulls to the right reset, and chassis portion 30a is replied from the two ends of the second cavity volume to middle part, live
Moving contact 32 is followed quarrel portion 30b and is moved to outside from enclosure interior, and breath oral area 300 also has outside to enter the sleeve keeping covering 2
In 21, due to sleeve 21 barrel internal diameter be less than breath oral area 300 thickness, breath oral area 300 in the presence of power pullled by spring in
Sleeve 21 and keep the junction of base plate 20 mutually to extrude, accommodating chamber 302 is closed, and disconnects accommodating chamber 302 and the first cavity volume
Connect, by the rigid sealing keeping set 2 to increased breath oral area 300.
The plastic material pressing splenium 33 using hard is as pressing button, and coordinates spacing barrel 13 and press gland wall 330, can
So that pressing splenium 33 there is certain anti-bending strength, even if press during pressure Impact direction producing crooked, also will not make to press pressure
Cannot stretch in portion 33.
Movable contact 32 is in T-shape, including contact end 321 and conductive contact bar portion 320, opens up in quarrel portion 30b
There are bar portion lock chamber 310 and end lock chamber 311, end lock chamber 311 is located at and presses the one of the corresponding silica gel leather cup 30 of splenium 33
Side, contact bar portion 320 is fixed in bar portion lock chamber 310, and contact end 321 is fixed in end lock chamber 311.
Bar portion lock chamber 310 and end lock chamber 311 effectively improve fixation in silica gel leather cup 30 for the movable contact 32, prevent
Stop skew and the dislocation abjection phenomenon that it produces in rubber cup 30 deformation and moving process.
First contact site 100 of the first binding post 10 adopts memory alloy material, and the first contact site 100 includes end
1000th, it is used for making arc contact portion 1001 detached with movable contact 32 curved with the arc contact portion 1001 of movable contact contact and heating
Folding part 1002；End 1000 is located at the two ends of the first contact site 100 and is fixed with enclosure interior, and kink 1002 is located at arc and touches
Between portion 1001 and end 1000.
The memory alloy material adopting in the present embodiment has a feature, that is, when the first contact site 100 temperature rises, curved
The bending angle of folding part 1002 can become big, and end 1000 is the fixation for the first contact site 100 two ends.
As shown in Figure 7 and Figure 8, when the power switching vigour part is excessive or transships, the electricity passing through in the first contact site 100
Stream is larger, and the heat of generation becomes many, and the first contact site 100 bulk temperature rises, because end 1000 two ends are fixing, therefore
Kink 1002 shrinks and close to two ends, and arc contact portion 1001 is overall to be offset to the left side, produces spacing simultaneously with movable contact 32
Disconnect with movable contact 32, now switch is off, it is to avoid electrical appliance overload is it is ensured that safety.
The above makes the preferred embodiment of the present invention, for the person of ordinary skill of the art without departing from this
On the premise of bright principle, some modifications and improvement can also be made, these also should be regarded as protection scope of the present invention.
