Abstract
The face that the utility model provides touches type low-tension fuse isolating switch, the upper end of moving knife plate is clamping plate structure upper slitter portion, two suppress parts is symmetricly set on upper slitter portion clamping plate outside, the described parts that suppress are T-shaped shell fragment, its intermediate is for suppressing tongue, it suppresses prying end and exerts pressure conflict outside touching the sub upper slitter portion clamping plate that contact with inlet wire portion, and its horizontal substrate laminating is fixed on upper slitter portion clamping plate.This structure has not only increased the active force that suppresses that suppresses tongue, has increased substantially upper slitter portion clamping plate and inlet wire portion simultaneously and has touched sub electrical contact performance, has simplified product, the especially package assembly of moving knife plate simultaneously.
Description
Technical field
The utility model relates to low-tension fuse isolating switch, relate in particular to the switch terminals fit structure of low-tension fuse isolating switch.
Background technology
The moving knife plate of low-tension fuse isolating switch moves and coordinates with the inlet wire portion lock of insulation support body upper end, moving knife plate is made up of the upper slitter portion of the clamping plate structure at middle insulation board and insulation board two ends and lower cutter portion, when combined floodgate, upper slitter portion tool will have enough clamping forces, could touch stable and good the electrically contacting of son with inlet wire portion and coordinate.Once symmetrical the conflict in the two rectangular spring clip settings in clamping plate outside that adopted in prior art that one end is fixed, other end prying is exerted pressure, its region of exerting pressure is narrow, and point of force application is inhomogeneous, and is difficult to form the face contact of designing requirement, affects electrical contact performance; In addition, spring clip is fixed by single bolt, and fixation built on the sand.
Summary of the invention
Goal of the invention of the present utility model is to change the upper slitter plate holder plate spring clip structure of moving knife plate, provides the stronger and more stable face of a kind of resilient clamp effect to touch type low-tension fuse isolating switch.The face that the utility model provides touches the technical scheme of type low-tension fuse isolating switch, its content is: a kind of face touches type low-tension fuse isolating switch, basic comprising comprises insulation support body, fixed installation portion, the inlet wire portion of insulation support body switch terminals and outlet portion, with inlet wire portion, the moving knife plate that outlet portion switch coordinates, the upper end of moving knife plate is clamping plate structure upper slitter portion, two suppress parts is symmetricly set on upper slitter portion clamping plate outside, the described parts that suppress are T shape shell fragment, its intermediate is for suppressing tongue, it suppresses prying end and exerts pressure conflict outside touching the sub upper slitter portion clamping plate that contact with inlet wire portion, its horizontal substrate laminating is fixed on upper slitter portion clamping plate.
Disclosed tactile type low-tension fuse isolating switch of the utility model, the parts that suppress in upper slitter portion clamping plate outside are designed to T shape sheet, centre is suppressed the elasticity reversal of stress of tongue warpage generation and is stretched to full wafer T shape sheet, act on upper slitter portion clamping plate comprehensively, this structure has not only increased the active force that suppresses that suppresses tongue, its elasticity reversal of stress also acts on lower cutter portion clamping plate comprehensively, increase substantially upper slitter portion clamping plate and inlet wire portion and touched sub electrical contact performance, simplified product, the especially package assembly of moving knife plate simultaneously.
