Abstract
The utility model relates to a rotatable small-size three-pole isolating switch. Two separating walls are upwards formed on a bottom surface in the housing and the bottom surface is divided into three contact spaces. Three sets of terminals are respectively equipped at two ends of each contact space at the bottom surface of the housing. Static contacts are connected with inside part of the terminals. Dynamic contacts are equipped above the static contacts. A spring is provided below the dynamic contacts. The separating walls correspond with the movable contacts and form a bracket sliding tank. A bracket is equipped above the movable contacts and is clamped in the bracket sliding tank. A rotating shaft is equipped above the bracket. Two symmetrical semicircular projected pressing blocks are downwards formed from the lower end surface of the rotating shaft along the circumference. The rotating shaft is interlocked with a handle through a connecting rod. The rotatable small-size three-pole isolating switch realizes a purpose of simultaneous switching on and off, and furthermore has the following advantages: simple structure, small volume, small space occupation in mounting, and low cost.
Description
Technical field
The utility model relates to a kind of small-sized isolating switch, especially a kind of rotary small-sized three-pole isolator.
Background technology
Three-pole isolator is the isolating switch for the three-phase alternating current system.General three operating mechanisms in three bases that adopt of existing three-pole isolator are formed, three operating mechanisms link to reach the effect of synchro switch together by handle, because three operating mechanisms switch triggering stroke separately has certain error, do not reach the effect of synchronous disconnection synchronizing close, can shine into certain infringement to electrical appliance, and the volume of three operating mechanisms is too fat to move, installation and maintenance inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of synchronous disjunction, rotary small-sized three-pole isolator simple in structure are provided.
For achieving the above object, the utility model adopts a kind of rotary small-sized three-pole isolator to comprise shell, handle and setting moving contact in the enclosure, fixed contact, spring, rotating shaft, connecting rod, support, screw, binding post, the bottom surface of enclosure upwards forms two partition walls the bottom surface is separated into three contact spaces, three winding line terminals are separately positioned on the two ends, contact space of shell bottom surface, fixed contact is connected the binding post inboard, moving contact is arranged on the fixed contact top, spring is arranged on the moving contact below, the corresponding moving contact of partition wall forms the support slippage slot, support is arranged on the moving contact top and is stuck in the support slippage slot, rotating shaft is arranged on the support top, the rotating shaft lower surface is along the circumferential briquetting that forms two semi-cylindrical hills of symmetry down, and rotating shaft is connected by connecting rod and handle.
Rotating shaft was also rotated thereupon together when operation principle of the present utility model was turning handle, when handle is rotated further and reach certain angle, the briquetting of rotating shaft support down motion in the base location notch with regard to roof pressure, support the active force that moving contact overcomes spring with regard to roof pressure and is down moved, thereby make dynamic and static contact transfer disconnection to by closure, when handle turned to the final position, dynamic and static contact separated fully, and switch is in off-state; When the handle counter-rotation and when reaching certain angle, mechanism's momentary reset under the reaction force of compression spring, switch turns back to closure state.
The utility model adopts above-mentioned operation principle, makes three-pole isolator reach the purpose of synchronous disconnection synchronizing close, and simple in structure, and volume is small and exquisite, and occupation space is little during installation, and is with low cost.
The utility model further is set to described connecting rod middle part and extends to form latch towards periphery, is provided with slide block around the latch, and slide block is buckled on the latch, is provided with handle spring between the slide block relative latch back side and the shell.The cooperation of latch and slide block is played positioning action to handle in rotation process.
The utility model further is set to form location hole on the described handle, and the corresponding location hole of small end forms fixing hole, and handle is provided with screw and passes location hole and be fixedly connected in the fixing hole on the connecting rod.
The utility model further is set to described shell both sides and is provided with annex location hole and annex location notch.Annex location hole on the shell and annex location notch make the assembly unit annex convenient, stable, reliable.
The utility model further is set to described handle and is provided with tool location apertures.Handle can be operated by instrument than tool location apertures big and that arrange.
The utility model further is set to described shell upper surface and forms safe lockhole in handle one side.Make things convenient for line maintenance and protection equipment safety operation.
