In order to facilitate above-mentioned technical proposal of the invention is understood, below by way of specifically used mode to above-mentioned skill of the invention
Art scheme is described in detail.
Upper body half 4, which is pressed on lower body half 5, constitutes ceramic tube body, the both ends of ceramic tube body is inserted in end cap 2, end cap
2 retention bead 9 is caught in the limiting groove of ceramic tube body, under the action of the first spring 7, upper body half 4, lower body half 5,
End cap 2 realizes that each hinged grip block 8 in the both ends of upper body half 4, each hinged one of the both ends of lower body half 5 press from both sides from locking
Plate 8 is held, when end cap 2 is inserted in respectively in the both ends of ceramic tube body, the pressure ring 10 in end cap 2 oppresses two grip blocks 8 up and down, makes
Upper and lower two grip blocks 8 are close to each other, and then clamp fuse 3 by upper and lower two grip blocks 8, in the effect of second spring 1
Under, grip block 8, fuse 3 are realized from locking.For convenience of the fixed and positioned of the first spring 7, in upper body half 4 and lower body half 5
It is provided with the blind hole matched with the first spring 7.
Grip block 8 is hinged by horizontal axis and ceramic tube body.Conductive contact between grip block 8 and fuse 3, grip block 8, pressure ring
10, end cap 2 is conductor.Pressure ring 10 can be contacted with 2 direct conduction of end cap, can also pass through conductive second spring 1 and end
Cap 2 is conductively connected.
Fuse 3 realizes the conductive connection with end cap 2 by grip block 8 and pressure ring 10.
There are multiple barrier blocks 6, fuse 3 is in buckling curve shape under the barrier of barrier blocks 6, using song in ceramic tube body
For the fuse 3 of wire shaped in fusing, the isolated spacing of the fuse 3 at ceramic tube body both ends is than very fast, when so that the fuse disconnecting
Between it is short, wherein for the ease of cut off fuse 3,6 triangular shape of barrier blocks.In the present embodiment, 4 inner wall of upper body half is by upper
Protruding out two pieces of barrier blocks 6 down, 5 inner wall of lower body half has protruded out three pieces of barrier blocks 6 from lower to upper, and intracorporal five pieces of ceramic tube
The alternate setting of barrier blocks 6.When the fuse 3 of the fuse fuses, what five pieces of barrier blocks 6 together generated the fusing of fuse 3
Electric arc is obstructed, and the arc extinguishing ability of fuse is improved, and is reduced the heat generated in 3 fusing process of fuse, is avoided fuse
The generation of spontaneous combustion explosion danger.
In use process, after fuse 3 fuses, upper body half 4 and lower body half 5 are pressed, makes to be located at 4 He of upper body half
The first spring 7 compression between lower body half 5, until the retention bead 9 of end cap 2 is deviate from out of limiting groove, then by end cap 2
It unloads, upper body half 4 and lower body half 5 is separated, take out the fuse 3 being broken, the fuse 3 for then intercepting corresponding length is pacified
Between upper body half 4 and lower body half 5, the two is protruded into end cap 2 after pressing upper body half 4 and lower body half 5 again,
And retention bead 9 is made to be caught in the replacement that fuse 3 can be realized in limiting groove, whole process is convenient and efficient, while in limit convex
Rise 9 be caught in limiting groove after, the second spring 1 in end cap 2 can squeeze pressure ring 10, two grip blocks up and down that pressure ring 10 is oppressed
8, close up upper and lower two grip blocks 8, to clamp fuse 3, fuse 3 is positioned by the gap slot of 8 vertex of grip block.
In conclusion the operation of change of fuse is relatively easy by means of above-mentioned technical proposal of the invention, it is ensured that
Ceramic tube body is used repeatedly, and is effectively reduced the waste of resource, using the fuse of curve shape in fusing, ceramic tube
The spacing of the fuse separation at body both ends, so that the fuse go ETAD expected time of arrival and departure is short, is obstructed than very fast by the several piece on ceramic tube body
Block obstructs the electric arc that fuse burning generates when fuse disconnects, and can quickly block electric arc, reduces fuse internal heat
It generates.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
