Fig. 1 to Fig. 3 shows a this specific embodiment for automatically disengaging formula power line of the application comprising mutually divides
From left line segment 1 and right line segment 2, left line segment 1 and right line segment 2 are made of multiply lametta.One end of left line segment 1 is (in Fig. 2
Right end) it is fixed with the left conductive sleeve 3 being conductively connected therewith, one end (left end in Fig. 2) of right line segment 2 is fixed with one therewith
The right conductive sleeve 4 being conductively connected.Aforementioned right conductive sleeve 4 and left conductive sleeve 3 are mutually permanently connected by snap component, and preceding institute
Snap component is limited to the coupling mechanism force of left and right conductive sleeve, when the right conductive sleeve 4 of outer bound pair and left conductive sleeve 3 apply sufficiently large pull
When power, previous mentioned snap component can be acted on by the power and be disengaged, so that right conductive sleeve 4 and left conductive sleeve 3 are separated from each other.It leads on a left side
Be connected with more fusible metal silks 5 between electricity set 3 and right conductive sleeve 4 --- i.e. low-melting-point metal silk, while on left conductive sleeve 3 and the right side
The pressure spring 6 in compressive state is folded between conductive sleeve 4.
(the various power described in behind i.e. are along on 6 axis direction of pressure spring on the axis direction of above-mentioned pressure spring 6
Power): the elastic force that 6 pairs of pressure spring left conductive sleeves 3 and right conductive sleeve 4 apply is greater than snap component to left conductive sleeve 3 and right conductive sleeve 4
Coupling mechanism force, and be less than snap component always breaking to left conductive sleeve 3 and 4 coupling mechanism force of right conductive sleeve and all fusible metal silks 5
The sum of power.That is, if (on the pressure spring axis direction) elastic force for defining 6 pairs of pressure spring left conductive sleeves 3 and right conductive sleeve 4 is
F1, defining snap component is F2 to the coupling mechanism force of left conductive sleeve 3 and right conductive sleeve 4 on pressure spring axis direction, is defined all easy
Molten total pull-off force of the wire 5 on pressure spring axis direction is that F3 (is drawn along the pulling force that pressure spring axis direction applies F3 size
These fusible metal silks 5 are pulled, these fusible metal silks 5 will will disconnect), there are F2 < F1 < (F2+F3) this size relations.
In practical application, by the separate end of line segment left in Fig. 11 and right line segment 2 be separately connected power supply (such as battery pack) and
Electrical equipment, one part of current successively flow to electrical equipment by left line segment 1, left conductive sleeve 3, right conductive sleeve 4 and right line segment 2,
Through fusible metal silk 5, by left conductive sleeve 3, conductive sleeve 4 transmits some electric current to the right simultaneously, so provides for electrical equipment
Operating current.When short circuit or other overcurrent (i.e. electric current is excessive) problems occur in the power supply line, had on fusible metal silk 5
Big electric current flows through, so that 5 heating temperature of fusible metal silk fuses after being rapidly increased to fusing point.At this moment, fusing is meltable
The tightening force of 5 pairs of wire left conductive sleeves 3 and right conductive sleeve 4 is zero, and the elastic force of 6 pairs of pressure spring left conductive sleeves 3 and right conductive sleeve 4
F1 is greater than snap component to the coupling mechanism force F2 of left conductive sleeve 3 and right conductive sleeve 4, therefore under the effect of 6 elastic force of pressure spring, snap component is de-
It opens, left conductive sleeve 3 and right conductive sleeve 4 are separated from each other, and left line segment 1 is completely disengaged with right line segment 2, and circuit disconnects.
Obviously, as long as the pull-off force of the quantity of our suitable configurations fusible metal silks 5 and single fusible metal silk 5,
Snap component can be opened by the elastic force of pressure spring 6 and residue is unblown after a part of fusible metal silk 5 is blown wherein
Fusible metal silk 5, guarantee Electrical Safety.Specifically it may be provided so that
Assuming that the fusible metal silk 5 connected between left conductive sleeve 3 and right conductive sleeve 4 shares N root, single fusible metal silk 5
Pull-off force on 6 axis direction of pressure spring is F0 (obvious F0 × N=F3), and n < N, n and N are natural number, only needs to guarantee [F2+
(N-n) × F0] < F1 < [F2+ (N-n+1) × F0], it may be assumed that after thering is n root to be blown in all N root fusible metal silks 5
(surplus N-n root is unblown), because of the coupling mechanism force F2 of total fusing power (the N-n) × F0 and snap component of remaining N-n root fusible metal silk 5
The sum of be less than pressure spring 6 spring F1, therefore snap component stress and disengage, the unblown 5 stress quilt of fusible metal silk of remaining N-n root
It breaks, left conductive sleeve 3 and right conductive sleeve 4 are separated from each other, and left line segment 1 is completely disengaged with right line segment 2, and circuit disconnects.
Above-mentioned n can be set to 1, it may be assumed that and after wherein any one fusible metal silk 5 fuses, which disconnects immediately,
The power line safety coefficient being designed in this way is very high, but occurs it is also a high possibility of wrong diagnosis opens.
It refers again to shown in Fig. 1 to Fig. 3, specifically in the present embodiment, N=6, n=3, it may be assumed that be provided with 6 meltable gold altogether
Belong to silk 5, after wherein 2 fusible metal silks 5 fuse because of excessive current, the elastic force of pressure spring is not enough to open snap component and remains
Remaining 4 fusible metal silks；And if wherein 3 molten wires 5 fuse because of excessive current, when there remains 3 fusible metal silks 5,
Under the effect of pressure spring elastic force, snap component is disengaged, and remaining 3 molten wires 5 are pulled off, which disconnects.
