It is coaxially arranged with external boss 310 on the periphery of column 201, perforative rotation up and down is offered on the periphery of external boss 310
Quote guide groove 311, rotates 45 degree of axial torsion of the inclination arrangement of guiding groove 311 and upper and lower ends along fixed column 201, institute
The rotation protrusion 309 for being fixedly installed on conductive slider 305 and matching with rotation guiding groove 311 is stated, it is right with conductive fuse 306
The lower end of the rotation protrusion 309 and rotation guiding groove 311 answered aligns.
Specifically, the axial direction in order to avoid conductive slider 305 around conductive slide bar 304 deflects, the conduction slide bar
It is opened up on 304 periphery and is parallel to its axial limit sliding chutes 304a, be provided on the conductive slider 305 and slided with limit
The spacing block set 305a that slot 304a matches, spacing block set 305a are matched with limit sliding chutes 304a for constraining conductive slider
305 rotation.
Fusing rotating mechanism 300 being embodied in during the work time, after conductive fuse 306 fuses, conduction is protected
The constraints of 306 pairs of dangerous silk corresponding triggering springs 308 will release, and user's debugging ircuit fault and cancel position-limit mechanism 400
After the rotational restraint of fusing rotating mechanism 300, the elastic potential energy of the triggering spring 308 will gradually be discharged and be pushed corresponding
Conductive slider 305 is slided along conductive slide bar 304 away from mounting rack 303, the corresponding rotation of conductive fuse 306 protrusion 309
It will be caught in by 311 lower end of rotation guiding groove, rotation guiding groove 311 is by guidance rotation protrusion 309 around the axial-rotation of fixed column 201
45 degree, and skidded off by the upper end of rotation guiding groove 311, at this point, the entirety of fusing rotating mechanism 300 will be around fixed column
201 axial 45 degree of rotation, makes the fuse 306 of fusing and corresponding contact 307 rotate 45 degree and conducting block
207 separation, meanwhile, so that completely new fuse 306 and corresponding contact 307 is rotated 45 degree and is connect with the conflict of conducting block 207
Logical, fusing rotating mechanism 300 rotates and restores automatically the connection to conductive plate 202 and conducting block 207, restoring circuit it is normal
Operation.
It is the scheme of optimization as the present invention, by rotation guiding groove 311 and rotates the mutual cooperation between protrusion 309,
The rotation of fusing rotating mechanism 300 is realized, in order to avoid the angle of its rotation is greater than 45 degree and leads to completely new insurance
306 corresponding contacts 307 of silk are slided along guide groove 206 and are fallen off with conducting block 207, for this reason, it may be necessary to guarantee fusing rotation
The angle that mechanism 300 rotates every time is exactly 45 degree, for this purpose, the external boss 310 is equipped with close to 303 one end of mounting rack
Block 312 for being limited to conductive slider 305, takes the meaning of this programme to be, it is ensured that fusing rotating mechanism 300 is every
The rotation of secondary rotation replacement fuse 306 is formed as 45 degree, on the one hand makes the completely new corresponding contact of fuse 306
307 contradict connection with conducting block 207, draw completely new fuse 306 corresponding rotation protrusion 309 after replacement with rotation
311 lower end of guide groove aligns.
If position-limit mechanism 400 does not constrain the rotation of fusing rotating mechanism 300, when fault current overload, make
Conductive fuse 306 fuse after, then without debugging ircuit fault before, fusing rotating mechanism 300 carry out at once rotation 45
It spends and replaces a completely new fuse 306, this kind of situation will result directly in the fusing of completely new fuse 306, for this purpose, when conduction
After fuse 306 fuses, position-limit mechanism 400 for the time being constrains the rotation of fusing rotating mechanism 300, when fault excludes
Afterwards, position-limit mechanism 400 is made to release the rotational restraint to fusing rotating mechanism 300, fusing rotating mechanism 300 will rotate completion automatically
The replacement of fuse 306 is handled, and circuit is made to restore to operate normally.
For this purpose, being bolted connection and the plug screw between the conduction slide bar 304 and adjustable shelf 301 close to insulation shell
120 closed end, one end face offers round limiting groove 401, and position-limit mechanism 400 includes the pin for being arranged in 120 closed end of insulation shell
Bar 403, pin rod 403 and insulation shell 120 along be parallel to fixed column 201 it is axial constitute slide-and-guide cooperation, 403 one end of pin rod to
It is outer extension and the end is provided with balanced handle 402, the other end is inserted into limiting groove 401, pass through pin rod 403 and limit
The cooperation of groove 401 constrains the rotation of fusing rotating mechanism 300.
Specifically, being provided with external step 404, the outside of pin rod 403 on the periphery of the medium position of the pin rod 403
It is arranged with holddown spring 405,405 one end of holddown spring and external step 404 is inconsistent, closing of the other end and insulation shell 120
It holds inconsistent and holddown spring 405 elastic force to be directed toward external step 404 by the closed end of insulation shell 120 always, passes through compression
Pin rod 403 is pushed and is inserted into limiting groove 401 by spring 405, realizes the rotational restraint to fusing rotating mechanism 300.
Being embodied in during the work time of position-limit mechanism 400, under original state, the elastic force of holddown spring 405 is by exhausted
External step 404 is directed toward in the closed end of edge shell 120, and the cooperation of pin rod 403 and limiting groove 401 is to fusing rotating mechanism 300
Rotation is constrained, and after conductive fuse 306 fuses, user excludes circuit to failure, then, pulls handle 402
Overcoming the elastic force of holddown spring 405 to act on makes pin rod 403 by withdrawing from limiting groove 401, makes 403 pairs of fusing rotating mechanisms of pin rod
300 rotational restraint releases, and fusing rotating mechanism 300 rotates 45 degree automatically and completes the replacement processing of fuse 306,
Circuit restores to operate normally.
