Description
Technical field
The present invention relates to circuit control device, it is auxiliary bullet formula waterproof rotary switch.
Background technology
Switch is the device for control circuit power on/off, but due to switch in lie substantially in energising state (i.e.
Voltage is maintained on live wire), therefore when the switch not used time, the circuit in switch still leaves electricity, when liquid access switch, by
Voltage is still maintained on live wire, the moment that liquid enters makes the short circuit in switch, lead to electrical equipment or switch to burn, deposit
In higher safety issue.
Meanwhile, if switch is in the higher environment of steam for a long time, steam is aging by acceleration switch internal circuit
And oxidation, lead to on-off control failure.
The circuit in liquid or moisture switch therefore how is stoped to be a problem demanding prompt solution.
Content of the invention

It is provided with the first binding post 10 being parallelly mounted to housing side and the second binding post 11, housing includes in housing
First cavity volume and the second cavity volume, the first binding post 10 end is provided with the first contact site 100, and the first contact site 100 is located at first
In cavity volume；Second binding post 11 end is provided with second connecting portion 110, and second connecting portion 110 is electrically connected with movable contact 32, the
Two connecting portions 110, movable contact 32 and silica gel leather cup 30 are respectively positioned in the second cavity volume.
It is additionally provided with holding set 2 and guiding conical plate 12 in housing.Keep set 2 to be fixed on enclosure interior, keep set 2 to be annular sleeve
Part, keeps set 2 longitudinal sections to be in " l " type, keeps set 2 to include sleeve 21 and keep base plate 20, quarrel portion 30b is sheathed on sleeve 21
Interior, the thickness of breath oral area 300 is more than the inwall radius of sleeve 21；When shift knob is not restored to the original state by external force, cease oral area 300
Extrude and close accommodating chamber 302 in sleeve 21 and holding base plate 20 intersection.Increase breath oral area 300 when silica gel leather cup 30 recovers
Sealing to accommodating chamber 302.
As shown in figure 3, silica gel leather cup 30 includes chassis portion 30a and quarrel portion 30b, 30a is disc-shaped in chassis portion, quarrel portion
In a tubular form, quarrel portion 30b is vertically connected at chassis portion 30a to 30b, chassis portion 30a be located at guiding conical plate 12 and keep base plate 20 it
Between.
The periphery of chassis portion 30a is fixed with inner walls phase by fold ring 301, fold ring 301 be located at chassis portion 30a and
Between inner walls, fold ring 301 ringwise wavy, fold ring 301 and chassis portion 30a are integrally formed setting, fold ring
301 can be compressed to a greater extent and be stretched it is ensured that chassis portion 30a can occur to deform to a greater extent.
It is provided with the accommodating chamber 302 accommodating movable contact 32, the connection of chassis portion 30a and quarrel portion 30b in the middle part of quarrel portion 30b
Place is provided with breath oral area 300, and the wall thickness of breath oral area 300 is more than the wall thickness of quarrel portion 30b.
Guiding conical plate 12 can guide to the moving direction of chassis portion 30a, and guiding conical plate 12 is tapered, guiding conical plate
12 are located between the first cavity volume and the second cavity volume, are provided with the through hole passing through for movable contact 32 in the middle part of guiding conical plate 12, and through hole is even
Logical first cavity volume and the second cavity volume.
As shown in Fig. 2 when knob 4 rotation makes pushing projection 40 extruding press splenium 33, spring is compressed, and presses splenium 33 and carries
Dynamic quarrel portion 30b moves to case inside, quarrel portion 30b extruding breath oral area 300 enter guiding conical plate 12 and keep base plate 20 it
Between, to the periphery side shifting of the second cavity volume, chassis portion 30a is extruded and drives fold ring 301 to deform chassis portion 30a, ceases oral area
300 also move to periphery, and the accommodating chamber 302 at middle part is opened, and the contact bar portion 320 of movable contact 32 passes through guiding conical plate 12
Through hole contact with the first contact site 100, realize being electrically connected of second connecting portion 110, movable contact 32 and the first contact site 100
Logical, safety switch assembly 1 is in connected state, safety switch assembly 1 closing of circuit.
As shown in figure 1, making pushing projection 40 depart from the contact with pressing splenium 33 when knob 4 rotates, pressing splenium 33 and being no longer subject to
Power, under the reset response of spring restoring force, will press splenium 33 to hull outside and eject, and quarrel portion 30b pulls to the right multiple
Position, chassis portion 30a is replied from the two ends of the second cavity volume to middle part, and it is outside by enclosure interior that movable contact 32 follows quarrel portion 30b
Portion moves, and breath oral area 300 also has outside to enter in the sleeve 21 keeping set 2, because the barrel internal diameter of sleeve 21 is less than breath oral area
300 thickness, breath oral area 300 mutually extrudes in the junction of sleeve 21 and holding base plate 20 in the presence of power pullled by spring,
Accommodating chamber 302 is closed, disconnects accommodating chamber 302 and the connection of the first cavity volume, breath oral area be increased by rigid holding set 2
300 sealing, simultaneously safety switch assembly home loop be changed into open a way, the connection of the first binding post and the second binding post
Disconnect, even if now there being steam to enter in accommodating chamber 302 from bar portion lock chamber 310, the extruding closing due to ceasing oral area 300 is made
With intercepting to steam, making the first cavity volume be in air-tight state, safety switch assembly 1 power-off.
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 " type, 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 silica gel leather cup 30 side pressing splenium 33 place,
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 is 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.
