At the both ends of body 201, upper moving contact 205 is arranged on upper bed-plate 203, and the lower moving contact 206 is connected by swing arm 207
Lower bottom base 204, bulb 208, limit angle 209 and fuse fixing device 210, the swing arm 207 1 are provided with lower bottom base 204
End axle is connected in lower bottom base 204, and other end axle is connected in fuse take-up device, and the fuse take-up device includes the He of locking spring plate 211
Back-moving spring 212, described one end of locking spring plate 211 are provided with cable clamping interface 213 and turned up, and other end cocker is stayed base 204
On limit angle 209；
As shown in Fig. 4,6,7, operation ring 214 is additionally provided with the upper bed-plate 203, the fuse 202 tenses with fuse
One end that device 210 connects is provided with buckle 215.
As shown in Fig. 4,6, in the present embodiment, the fuse fixing device 210 includes square washer 216 and square spacing
Groove 217, the square washer 216 can be arranged in stopper slot 217 by screw and bolt 218, be moved down when on square washer 216
When dynamic, due to the limitation of square stopper slot 217, square washer 216 can not rotate, and the angle rotated in other words is very small, will not
Big to fuse generation pulls effect.
As shown in Fig. 3,5,6, the lower static contact 13 is double hook-shape structures, and the both sides of the swing arm 207 are each provided with
One positioning convex point 218, the ultimate range on two positioning convex points 218 is slightly less than the distance of double hook in lower static contact 13, with small 1-
4mm is advisable.
Embodiment 2
As shown in Figure 1, 2, 3, compared with Example 1, in the present embodiment, the upper static contact 12 is additionally provided with rain-proof above
Cover 14, side, the side of upper moving contact 205, the side of lower static contact 13, the side of lower moving contact 206 of the rain cover 14

More preferably, arc extinguishing board 16 is additionally provided with the upper static contact 12, drainage plate is additionally provided with the lower bottom base 204
17。
Embodiment 3
As shown in figure 8, a kind of operation instrument, for installing above-mentioned fuse switch, including lever 31 and operating head
32, horizontal transverse arm 321 is set on the operating head 32, anti-slip veins or antiskid groove, transverse arm are provided with the transverse arm 321
The 321 operation rings 214 that can be inserted on foregoing drop-type circuit breaker upper bed-plates 203, are provided with arc on the end face of the operating head 32
Face groove 322, the cambered surface groove 322 are engaged with the bulb 208 on lower bottom base 204, i.e., the cambered surface of cambered surface groove 322 can be held
Receive bulb 208 so that when fusion tube 2 is hung on the cambered surface groove 322 of operation instrument by bulb 208, even if operation instrument with it is molten
Produce very big angle change between pipe 2, fusion tube 2 is all without dropping.
The present invention operation principle be：
When installation, replacing fuse, fuse is passed through to the body of fusion tube, the upper moving contact of one end connection, the other end is lower dynamic tactile
Head end stretches out, while pushes locking spring plate to body, the cable clamping interface for making the fuse of stretching body enter on locking spring plate, buckle across
Cable clamping interface is crossed, locking spring plate tenses the fuse in body in the presence of buckle, and turning up on locking spring plate is partly played anti-
The effect that only fuse skids off out of cable clamping interface, the fuse of stretching are positioned under square washer again, turn screw, make square washer will
Fuse compresses.By comparison, conventional mounting mode is twisted by way of circular gasket adds screw, with locking spring plate in the present invention
The part for playing phase same-action is elasticity pressure tongue, and when this results in turning screw, fuse easily follows screw to rotate, and causes fuse to be got over
Draw tighter, if fuse is left blank too small, fuse can be broken, if fuse is left blank excessive, fuse relaxation, influence safety, and
How much it is uncontrollable that fuse if turning, cause fuse leave blank can not accurate perception, have a strong impact on the reliability of power supply.It is of the invention then
It can ensure that the fuse in fusion tube keeps tension, regardless of whether the fuse length outside body, when being compressed by screw, square washer
It is stuck in stopper slot, mode pad will not rotate, and fuse will not rotate naturally, ensure the reliable of connection.
When setting up or removing fusion tube, the bulb of fusion tube is placed in the arc groove of operation instrument, hangs over operation
On instrument, there can be very big angle between operation instrument and fusion tube in all directions.Conventional mounting instrument does not have arc
Connected in star, also a cyclic structure is only inserted by transverse arm and moves up and down fusion tube without bulb with matching on fusion tube,
Only there is the free degree in a perpendicular, if operation instrument or fusion tube are slightly inclined, fusion tube is easy to fall off to fall down, and influences to pacify
Dress.
Light is not strong or bad environments in the case of fusion tube is installed when, because fusion tube installation site is high, installation personnel is only
With visually observing, it is difficult to ensure that being installed in place.The present invention has sticked reflector in corresponding place, if shone during installation with light source
Penetrate, then have very strong reflective, whether installation personnel is easy for seeing clearly and is installed in place.Meanwhile swing arm both sides are provided with and determined
Position is raised, when fusion tube to be linked into the double hook of lower static contact, it is ensured that fusion tube hangs over the centre position of double hook, it is ensured that fusion tube is suitable
Profit is linked into double hook.
Embodiment of the present invention is only the description carried out to the preferred embodiment of the present invention, not to the present invention
Spirit and scope are defined, and on the premise of design philosophy of the present invention is not departed from, engineers and technicians are to this hair in this area
The all variations and modifications that bright technical scheme is made, protection scope of the present invention, the claimed skill of the present invention all should be fallen into
Art content, all record in detail in the claims.
