First 205, lower moving contact 206, the upper bed-plate 203 and lower bottom base 204 are arranged respectively in the both ends of tube body 201, upper moving contact 205
It is arranged on upper bed-plate 203, the lower moving contact 206 connects lower bottom base 204 by swing arm 207, is provided on lower bottom base 204
Bulb 208, limit angle 209 and molten wire fixing device 210,207 one end axis of swing arm are connected in lower bottom base 204, other end axis
It is connected in fuse tension device, the fuse tension device includes locking spring plate 211 and reset spring 212, the locking spring plate 211
One end is provided with cable clamping interface 213 and turns up, and the other end can block the limit angle 209 on lower bottom base 204；
As shown in Fig. 4,6,7, operation ring 214 is additionally provided on the upper bed-plate 203, the fuse 202 is tensed with fuse
One end that device 210 connects is provided with buckle 215.
As shown in Fig. 4,6, in the present embodiment, the molten wire fixing device 210 includes square washer 216 and rectangular limit
Slot 217, the square washer 216 can be arranged in limiting slot 217 by screw and bolt 218, be moved down when on square washer 216
When dynamic, due to the limitation of rectangular limiting slot 217, square washer 216 cannot 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 two sides of the swing arm 207 are each provided with
One positioning convex point 218, the maximum distance 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, the side of the rain cover 14, the side of upper moving contact 205, the side of lower static contact 13, lower moving contact 206 side
Reflector block 15 is provided with on operation ring 214.
More preferably, it is additionally provided with arc extinguishing board 16 on the upper static contact 12, is additionally provided with drainage plate on the lower bottom base 204
17。
Embodiment 3
As shown in figure 8, a kind of operational instrument, for installing above-mentioned fuse switch, including lever 31 and operating head
32, lateral transverse arm 321 is set on the operating head 32, is provided with anti-skid chequer or antiskid groove, transverse arm on the transverse arm 321
321 can be inserted into the operation ring 214 on aforementioned drop-type circuit breaker upper bed-plate 203, be provided with arc on the end face of the operating head 32
Face groove 322, the cambered surface groove 322 are matched with the bulb 208 on lower bottom base 204, i.e., the cambered surface of cambered surface groove 322 can be held
Bulb 208 is received, when so that fusion tube 2 being hung on the cambered surface groove 322 of operational instrument by bulb 208, even if operational instrument and molten
Very big angle change is generated between pipe 2, fusion tube 2 is not all fallen out.
The working principle of the invention is:
When installation, replacement fuse, fuse is passed through to the tube body of fusion tube, one end connects upper moving contact, and the other end is in lower dynamic touching
Head end stretches out, while pushing locking spring plate to tube body, and the fuse for stretching out tube body is made to enter the cable clamping interface on locking spring plate, buckle across
Cable clamping interface is crossed, locking spring plate will manage intracorporal fuse under the action of buckle and tense, and turning up on locking spring plate is partially played anti-
The fuse of the only effect that fuse is skidded off out of cable clamping interface, stretching is placed under square washer again, turns screw, makes square washer will
Fuse compresses.In contrast, conventional mounting mode is twisted in such a way that 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 fuse is caused to be got over
Draw tighter, if fuse is left a blank too small, fuse can be broken, if fuse is left a blank excessive, fuse relaxation influences safety, and
Fuse turn how much be it is uncontrollable, cause fuse leave a blank can not accurate perception, seriously affect the reliability of power supply.The present invention is then
It can guarantee that the fuse in fusion tube keeps tension, regardless of the fuse length outside tube body, when being compressed by screw, square washer
It is stuck in limiting slot, mode gasket not can rotate, and fuse will not rotate naturally, guarantee the reliable of connection.
When setting up or removing fusion tube, the bulb of fusion tube is placed in the arc groove of operational instrument, hangs over operation
On tool, there can be very big angle between operational instrument and fusion tube in all directions.Conventional mounting tool does not have arc
Connected in star is only inserted into a cyclic structure by transverse arm and moves up and down fusion tube also without bulb with matching on fusion tube,
Only there is freedom degree in a perpendicular, if operational instrument or fusion tube are slightly inclined, fusion tube is easy to fall off to be fallen down, and influences to pacify
Dress.
In the case where light is not strong or bad environments when installation fusion tube, since 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 when installation with light source
It penetrates, there will be very strong reflective, whether installation personnel is easy for seeing clearly and be installed in place.Meanwhile swing arm two sides are provided with and determine
Position protrusion, when fusion tube to be linked into the double hook of lower static contact, it is ensured that fusion tube hangs over the middle position of double hook, it is ensured that fusion tube is suitable
Benefit 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
Conception and scope is defined, and under the premise of not departing from design philosophy of the present invention, engineers and technicians are to this hair in this field
The all variations and modifications that bright technical solution is made should all fall into protection scope of the present invention, the claimed skill of the present invention
Art content, is all described in the claims.
