Description
Technical field
The utility model relates to electric switch field, is specifically related to a kind of isolating switch.
Background technology
At present, isolating switch be used in low-voltage circuit rise connection, disjunction and line maintenance time do isolate device for switching.Existing isolating switch is rotated by operating grip, the action of operating grip band pneumatic operating mechanism, thus operating mechanism drives contact action, realize the on-off with fixed contact, but, the structural design of the operating mechanism of existing isolating switch is compact not, thus there is unstable properties in this isolating switch, dynamic/static contact connects not compact defect, and the dynamic/static contact of existing isolating switch is all adopt pure copper material to make, when there is moment circuital current in circuit, this dynamic/static contact is easily burnt, thus the useful life of this isolating switch is shorter.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides the isolating switch of a kind of compact conformation, stable performance, long service life.
For achieving the above object, the utility model adopts a kind of isolating switch, comprise upper cover, middle cover, base, be arranged on the operating mechanism in upper cover, three groups of fixed contacts of the base both sides arranged, be arranged on the movable block in base, corresponding each group fixed contact place is arranged on the moving contact on movable block, described operating mechanism comprises handle, to link the rotating shaft arranged with handle, be arranged on the gathering sill of C-shaped shape in rotating shaft, be arranged on the pulley in gathering sill, be connected to the torsion spring between pulley and upper cover, be arranged on the slide block in the chute that covers, the lower end of the corresponding pulley in both sides of described slide block is provided with corresponding baffle plate, and the lower end of slide block is arranged in the installing hole on movable block through described chute, described slide block can reciprocatingly slide in the chute of middle cover with pulley action and movable block reciprocating action in base described in driving, realize the connection of moving contact and fixed contact, disconnect.
The beneficial effect of said structure is: this isolating switch is when operating, operating personnel's turning handle, handle drives axis of rotation, the action in gathering sill of rotating shaft band movable pulley, baffle plate on sheave propels slide block and band movable slider in action in the chute that covers, slide block drives movable block action in base, thus movable block drives connection, the disconnection of each moving contact and corresponding fixed contact.Thus the operating mechanism of this isolating switch has structure is simple, structural design is compact advantage.
The lower contact that described each moving contact includes contact, correspondence is arranged on contact lower end, the upper shell fragment be arranged on contact upper surface, the lower shell fragment be arranged on lower contact lower surface.By arranging corresponding shell fragment on the upper and lower contact of moving contact, it is compacter that this shell fragment can ensure that upper and lower contact is connected with fixed contact, avoid moving contact to contact with the bad of fixed contact, and the dynamic/static contact of this isolating switch all adopts Copper-iron alloy material to make, the dynamic/static contact that this material is made is higher than the fusing point of existing fine copper contact, when there is instantaneous short circuit electric current in circuit, and can not be excessive because of electric current, and burn dynamic/static contact, thus extend the useful life of this isolating switch.
