Efficiency.
This fuse switch 100 also includes falling device 104.This falls device 104 and includes the first conduction of band hook and slot 1401
Seat 104a and the second conductive seat 104b of band peg 1402.First conductive seat 104a is connected with the lower end of insulator 101.Wherein,
First conductive seat 104a is also formed by corrosion resistant plate punching press, and the first conductive seat 104a includes the lower end phase with insulator 101
Base portion 1403 even and two sidewalls 1404 relative to each other.Two sidewalls 1404 all extend to the right from base portion 1403, hook and slot
The quantity of 1401 is two, and two hook and slot 1401 are respectively formed on two sidewalls 1404.
The rainhat 103 and the first conductive seat 104a of the fuse switch 100 of the embodiment of the present invention is all by rustless steel
Plate is stamped to form, and inherently has higher intensity and preferable resistance to corrosion, it is ensured that fuse switch 100 is the most perishable
Alteration shape.On this basis, this rainhat 103 and the first conductive seat 104a combines with respective ad hoc structure again so that each
It is enhanced again from bulk strength, thus ensures that the overall structure of fuse switch 100 is stable.In addition, rustless steel
Plate impact style is than conventional cast mode more fast and reliable, it is easy to improve rainhat 103 and the production of the first conductive seat 104a
Efficiency, thus improve the production efficiency of fuse switch 100.
This fuse switch 100 also includes fusion tube 102.This fusion tube 102 includes body and the pressure releasing cap being connected with each other, institute
State body lower end to be connected with the second conductive seat 104b, and be hung on the first conductive seat by the peg 1402 of the second conductive seat 104b
In the hook and slot 1401 of 104a.Fusion tube 102 can carry out upwards S1 and the rotation of downward S2 relative to insulator 101.When fusion tube 102
When rotating along upwards S1 direction relative to insulator 10, the draw-in groove by being connected in conductive member 106 of the upper end of fusion tube 102
In.As it is shown on figure 3, pressure releasing cap 1022 includes that the be connected with body first connection end is connected with the second of conductive member phase clamping
End and the connecting portion being located between the first connection end and the second connection end, the sidewall of connecting portion is provided with release of pressure blind hole 10221, releases
The release of pressure when pressure that pressure blind hole 10221 is configured in body exceedes preset pressure.
When the high voltage fuse in body meets fault fusing, the place of disconnection there will be electric arc, in the effect down tube of electric arc
The material in internal portion can produce gas, makes the pressure in body increase, when in body, pressure reaches default force value, and release of pressure
The release of pressure blind hole 10221 of cap will become through hole release of pressure, the gas in body can to the upper end arc blow-out of body and from through hole discharge,
Now can realize the upper and lower two-way rapid air injection of body, thus improve the arc extinction performance of this fuse switch 100, it is to avoid safety is hidden
Suffer from.
Fig. 4 is the partial sectional view of the first conductive seat of the fuse switch according to the embodiment of the present invention；According to Fig. 5
The structural representation of the second conductive seat of the fuse switch of the embodiment of the present invention.First conductive seat 104a is provided with arc
Gathering sill 104c, and it is provided with, on the second conductive seat 104b, guide protrusions 104d matched with arc guide groove 104c.Wherein,
When fusion tube 102 is positioned at extreme higher position (position shown in Fig. 1), the draw-in groove phase clamping of the upper end of fusion tube 102 and conductive member 106,
Guide protrusions 104d is positioned at arc guide groove 104c；When fusion tube 102 turns to extreme lower position, guide protrusions 104d skids off arc
Gathering sill 104c, to allow the peg 1402 of the second conductive seat 104b to depart from the hook and slot 1401 of the first conductive seat 104a；When molten
When the pipe 102 position between extreme higher position and extreme lower position rotates, guide protrusions 104d is always positioned at arc guide groove 104c
In, to stop the peg 1402 of the second conductive seat 104b to depart from the hook and slot 1401 of the first conductive seat 104a.By above-mentioned side
Formula, the fuse switch 100 of the present invention is by the arc guide groove 104c being fitted to each other and guide protrusions 104d, it is ensured that
Fusion tube 102 departs from insulator 101 in damaging falling process the most on one's own initiative, thus avoids fusion tube 102 to inadvertently fall off and injure people by a crashing object
Or thing.In order to make the more smooth and easy motion in arc guide groove 104c of guide protrusions 104d, guide protrusions 104d be shaped as cylinder
Shape or hemispherical.
In the present embodiment, the distance between two lamellar guide part 103b is gradually increased along direction from left to right.
In this way, rainhat 103 can guide the upper end of fusion tube 102 to enter in the draw-in groove of conductive member 6 swimmingly.
