Described misoperation-proof mechanism is arranged on plug-in strip plate and the hinged one end of fixed contact, mainly comprises hinged being arranged at and plug-in strip plate stirs lock fork; Described lock fork outer end of stirring is handlebar, and the below of handlebar is provided with stirs lock fork spacer pin; Described struck side of stirring lock fork is that the plug-in strip plate combined floodgate lock that locking with the lock-bit plate being fixed on the hinged fixed contact of plug-in strip plate in V-shape is opened, locking coordinates refers to lock with plug-in strip plate separating brake refer to; Described lock-bit plate to stir lock fork stir in corresponding lock refer to realize locking open, the cooperation position of locking is provided with plug-in strip plate combined floodgate lock-bit groove and plug-in strip plate separating brake lock-bit groove; Described lock-bit spring one end hang on the fixed contact of plug-in strip plate hinged side, and the other end hang on to be stirred outside lock fork jointed shaft between two locks refer to.
In the present invention, moving contact, inlet wire plate are integrated, namely directly adopt a part for inlet wire plate as moving contact, avoid the existence of weld crack, efficiently solve because weld seam exists and produce a series of problem; And this structure does not need to carry out process modification, only by inlet wire plate proper extension, need then be processed into L shape.In addition, on moving contact, be also provided with a through hole, namely provide one " locked groove ", coordinate locker, form effective padlock function, prevent when "on" position, plug-in strip plate departs from moving contact.The misoperation-proof mechanism set up effectively can also overcome the potential safety hazard of existing product, and realizing plug-in strip plate can not with misoperation action in combined floodgate or gate-dividing state, thus ensures that product is in the reliability of distribution line and fail safe.
Further illustrate as of the present invention, described flash guard comprises and being arranged on insulator pillar and the preventing arc fixed contact of the high-quality red copper material be connected with inlet wire plate and be arranged on the preventing arc moving contact of the high-quality red copper material on plug-in strip plate.Flash guard can not produce electric arc, handling safety when ensure that folding switch.
Further illustrate as of the present invention, the rear end of described plug-in strip plate is contained on fixed contact by long-neck bolt, compression spring and nut clip, the front end of plug-in strip plate clamps locker, and fix by long-neck bolt and compression spring and be interconnected, the range line finger ring that locker and plug-in strip plate top end clamp forms the embedding embedding clip slot being sandwiched in moving contact.
Further illustrate as of the present invention, described compression spring is nested with on the long-neck bolt outside plug-in strip plate two ends one, and compression spring two ends are respectively arranged with the compression spring guard shield for being limited to by compression spring on bolt.
Further illustrate as of the present invention, the side, rear end of described plug-in strip plate is provided with limiting plate.
Do with the clubs of insulation structure during isolating switch deciliter, insulation structure rod fastens isolating switch latch hook, pull latch hook to separating brake direction, drive the conductive plate be attached thereto to rotate after untiing self-locking device and realize separating brake action, withstanding isolating switch latch hook by insulated hook rod during combined floodgate drives rotating shaft to select dress, make it connected conductive plate and turn to closing position, now isolating switch is locked in closing position by self-locking device.
Compared with prior art, the beneficial effect that has of the present invention:
1. safe and reliable, conduct electricity very well, bulk strength is high, long service life.By terminal block proper extension, be then processed into L shape, bossing, as moving contact, realizes moving contact and the seamless link of inlet wire plate, effectively prevent the issuable various problem because of weld seam.
2. set up misoperation-proof mechanism, effectively prevent the operations such as "on" position mistake is divided, the conjunction of gate-dividing state mistake, ensure that circuit secure safety.Set up flash guard, when ensure that folding switch, can not electric arc have been produced, handling safety.
3. structure is simple, and processing cost is low, is beneficial to and promotes the use of.
