There is no intermediary elements.Term as used herein " vertically ", " horizontal ", "left", "right" and similar statement are
For illustrative purposes.
As shown in Figure 5 and Figure 6, the movable contact spring 100 for switching device of one embodiment of the utility model, including being connected
Driving portion 110 and contact site 120；110 arc-shaped plate of driving portion, abuts for the sliding block 210 with switching device；Contact site
120 are arranged on one end of driving portion 110, are contacted for the contact 220 with switching device.
Support plate 230 is provided between driving portion 110 and switching device, support plate 230 has plays branch to driving portion 110
The supporting point of support effect.Driving portion 110 can be left under the action of the sliding block 210 of switching device using supporting point as oscillation center
Right swing, to realize the contact of contact site 120 and the contact 220 of switching device or separate.
Specifically, driving portion 110 has first area 111 and second area 112, first area 111 and second area 112
It is located at the both sides of supporting point respectively.When the sliding block 210 of switching device is abutted with first area 111, contact site 120 and switching device
Contact 220 contact (such as Fig. 9).When the sliding block 210 of switching device is abutted with second area 112, contact site 120 and switching device
Contact 220 separate (such as Figure 10).
When contact site 120 is fixed with the contact 220 of switching device to be contacted, second area 112 is to the sliding block of switching device
210 generations make the torque (such as Fig. 6) that the sliding block 210 of switching device is moved to first area 111.
It should be noted that fixed contact refers to that the contact 220 of contact site 120 and switching device is the improper beginning
Whole contact condition.Generally in switching device by experiment, can by 220 melting welding of contact of contact site 120 and switching device, with
Carry out safety test.And during the use of switching device, it is also possible to contact site 120 be caused to fill with switch since temperature is excessively high
The contact 220 put is welded together.Then for security consideration, it would be desirable to ensure the contact in contact site 120 and switching device
220 be when fixing the state of contact, and the button 240 of switch is during pressing, it is impossible to rest on off position, i.e., such as Fig. 6
Shown key position.As shown in fig. 6, button 240 at this time is in and reports cold position by mistake, and in fact, switching at this time
It is switched on the state of (contact site 120 is contacted with contact 220).
Wherein, the shape of driving portion 110 can be it is a variety of, such as：Driving portion 110 can be elongated arc plate,
Or driving portion 110 can be in the modified long arc shape plate of width, as long as 110 arc-shaped plate of driving portion.In addition,
Driving portion 110 can be the arc panel of single curvature radius, or the modified arc panel of radius of curvature, as long as can
Ensure that second area 112 produces the sliding block 210 of switching device when contact site 120 is fixed with the contact 220 of switching device and contacted
Life makes the torque that the sliding block 210 of switching device is moved to first area 111.In other words, when contact site 120 and switch fill
When contact is fixed in the contact 220 put, if the sliding block 210 of switching device is connected on second area 112, then the cunning of switching device
Block 210 will necessarily be moved to first area 111, and can not rest on off position.In this way, be not in that wrong report is cold
Situation.
Further analysis is when contact site 120 is fixed with the contact 220 of switching device and contacted, the sliding block 210 of switching device
Understand that the sliding block 210 of switching device is connected to second area 112 under this state in the stressing conditions of above-mentioned off position,
It is far longer than the frictional force between sliding block 210 and driving portion 110, therefore, the cunning of switching device along the component on 110 surface of driving portion
The trend of 210 oriented first area 111 of block movement.As above-mentioned second area 112 makes the generation of sliding block 210 of switching device
The torque that the sliding block 210 of switching device is moved to first area 111.
And the radian shape of the driving portion 110 of arc plate, it is main to determine no matter its radius of curvature changes or do not change
When contact site 120 is fixed with the contact 220 of switching device to be contacted, the sliding block 210 and second area 112 of switching device contact
The tangential direction at place and the size of the angle in the direction of sliding block active force.In this way, when effect of the sliding block 210 to second area 112
One timing of power by rationally designing the size of foregoing angle, can be realized when the contact 220 of contact site 120 and switching device is solid
When contacting surely, the component along 110 surface of driving portion that the sliding block 210 of switching device is acted on second area 112 is far longer than
Frictional force between sliding block 210 and second area 112 so that 210 unstability of sliding block and moved to first area 111, so as to sliding
Block 210 will not rest on foregoing off position.210 unstability of sliding block is without resting on off position, i.e., button 240 will not
Rest on off position.Wherein, off position is the position of the button 240 shown in Fig. 6.
Referring to Fig. 6, Fig. 7 and Fig. 8, the sliding block 210 of switching device is driven by the button 240 of switching device, and passes through spring
242 connection sliding blocks 210 and button 240.When contact site 120 is fixed with contact 220 to be contacted：
According to sliding block 210 at this time second area 112 force analysis, for sliding block 210, be subject to spring power and
The power of movable contact spring.The power of spring is according to the decrement of spring 242, it is assumed that 242 length of spring is 2.7mm, then can calculate spring
Power K=33N, and axis direction of the direction of the power of spring along sliding block 210.And sliding block 210 is to active force of driving portion 110 etc.
The power of spring is same as, is all K.
The driving portion 110 of movable contact spring 100 can give 210 1 reaction forces of sliding block, this is anti-because of the effect of the power of sliding block 210
Active force is equal with sliding block active force K, is also 33N, and the two direction is opposite.
Assuming that the corner dimension of the tangential direction of 112 contact position of sliding block 210 and second area and sliding block force direction is α
=54.5 °；Then above-mentioned reaction force can be equivalent to normal direction holding power Fn and one along the downward component Fx in contact position, according to conjunction
Power component parallelogram law calculates, Fn=Ksin α=26.87N, Fx=Kcos α=19.16N.
Due to the presence of Fx component, the trend of 210 oriented first area 111 of sliding block movement, so there are a negative directions
Frictional force F, it is assumed that F=μ Fn=4N can be calculated according to friction formula in friction coefficient μ=0.15.
Therefore, because Fx is much larger than F, therefore sliding block 210 cannot keep in off position, and in this position, sliding block 210 is in
Instability status and can be moved towards the direction of component Fx, i.e. sliding block 210 can move to the position abutted with first area 111, so as to
So that button 240 is rotated clockwise to position of the normal instruction switch for "on" position (referring to Fig. 9).So so that button
240 be not in error indication (such as product itself is powered, and but indicates no power), realizes the mesh of experiment purpose and protection safety
's.
It should be noted that error indication refers to, it is place that the button 240 of switching device, which can generally be equipped with and be used to indicate switch,
In the red point for the state or the state of pass opened, it can see that show point represents that switch is to open, it is impossible to see that show point represents switch
It is to close.Under normal circumstances, when the contact 220 of switching device is contacted with contact site 120, the opening for energization is switched
(such as Fig. 9) conversely, when contact 220 is disconnected with contact site 120, is switched as cold closed state (such as Figure 10).
Therefore, when contact 220 is contacted with 120 improper fixation of contact site, if without above-mentioned sliding block unstability situation,
It cannot be guaranteed that the button 240 of switch during pressing, remains at the position that instruction power supply is connected, i.e., it can not avoid mistake
The situation of instruction, there are great security risks.
In this way, the movable contact spring for switching device of the present embodiment, can ensure in contact site 120 and 220 melting welding of contact
When, make 210 unstability of sliding block, ensure that switching device is designated as the state of power supply connection always under the abnormal condition, avoid out
