Description
Technical field
The utility model relates to low-tension fuse isolating switch.
Background technology
The moving knife plate that inlet wire portion, outlet portion and the chain connection that the basic composition member of low-tension fuse isolating switch comprises insulation support body, fixed part, insulation support body switch terminals coordinates in outlet portion, with inlet wire portion switch, integral installation is generally the setting use state that moving knife plate side has a down dip, only rely on moving knife plate holder board clamping to be engaged in inlet wire portion and touch upper its "on" position that keeps of son, the phenomenon that cannot avoid the unexpected slippage of moving knife plate to separate, causes electric accident.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of locking type low-tension fuse isolating switch of the unexpected separating brake obscission of avoiding abnormal operation appearance.The locking type low-tension fuse isolating switch technical scheme that the utility model provides, its main technical content is: a kind of locking type low-tension fuse isolating switch, its formation comprises insulation support body, fixed part, the inlet wire portion of insulation support body switch terminals, outlet portion and with inlet wire portion, the moving knife plate that outlet portion switch coordinates, the intermediate insulation plate two ends of moving knife plate are upper slitter portion and the lower cutter portion of clamping plate structures, on locating shaft in the hinged clip slot being arranged between upper slitter portion clamping plate of combined floodgate latch hook, spacing being slidably matched of alignment pin in limit sliding chutes and the clip slot of combined floodgate latch hook, it on combined floodgate latch hook, is the moving operation ring of lock, under be provided with inlet wire portion and touch the latch hook that coordinates of sub-edge lock hanging, torsion spring with locating shaft for turning round axle, one end borrows masterpiece to be used in clip slot inner side, the other end is turned round and is hung on combined floodgate latch hook.
The disclosed locking type low-tension fuse of the utility model isolating switch technical scheme, has effectively avoided moving knife plate accidental to cause the appearance of separating brake phenomenon, has guaranteed the normal operation of power circuit.
Brief description of the drawings
Fig. 1 is Structural Tectonics figure of the present utility model, is to remove the upper slitter portion of moving knife plate and total structural map of lower knife plate one side clamping plate.
Fig. 2 is that the A of Fig. 1 is to structure chart.
Embodiment
The disclosed locking type low-tension fuse of the utility model isolating switch, chief component member comprises that inlet wire portion 3, outlet portion 5 and the switch of insulation support body 1, fixed part 2, insulation support body 1 and its switch terminals are connected in the moving knife plate between inlet wire portion 3 and outlet portion 5.Moving knife plate is made up of middle insulation board 4 and the upper slitter portion 11 and the lower cutter portion 12 that are fixed on the clamping plate structure at insulation board 4 two ends, combined floodgate latch hook is arranged in the clip slot between the clamping plate of upper slitter portion 11, on the hinged locating shaft 6 being arranged in clip slot, the limit sliding chutes of combined floodgate latch hook and spacing moving cooperation of alignment pin 7 in clip slot, limit sealed position and the unhook limit position of combined floodgate latch hook.On combined floodgate latch hook, be the moving operation ring 8 of lock, under latch hook 9 touch the lock hanging of sub-edge with inlet wire portion 3 and coordinate, the outside of latch hook 9 is oriented sliding surface 19, when combined floodgate, minimizing is with respect to the tactile sub sliding resistance of inlet wire portion 3; Torsion spring 10 is with locating shaft 6 for turning round axle, and one end borrows masterpiece for clip slot inner side, and the other end is turned round and hung on combined floodgate latch hook.
When this low-tension fuse isolating switch is in "on" position, while needing sub-switching operation, action bars catches on and upwards lifts the moving operation ring 8 of lock, force combined floodgate latch hook to rotate, make latch hook 9 depart from inlet wire portion 3 and touch sub-edge, again continue to pull out the moving operation ring 8 of lock thereafter, make moving knife plate depart from inlet wire portion 3, complete separating brake; When closing operation, action bars catches on the moving operation ring 8 of lock, drive moving knife plate to rotate near inlet wire portion 3, when latch hook 9 outside inclination sliding surfaces 19 are slided by the tactile sub-lateral margin of inlet wire portion, also making inlet wire portion 3 touch son progresses between the clamping plate of upper slitter portion 11, until latch hook 9 is final and inlet wire portion 3 touches after sub-edge hook lock, it is upper that the clamping plate of upper slitter portion 11 are also clamped at the tactile son of inlet wire portion 3, and combined floodgate coordinates.
Claims (2)
