Abstract
The utility model discloses a selection switch for switching without disturbance. The selection switch comprises a handle, a rotating shaft, a positioning system, a base and a cam assembly. By changing the appearance of the cam: when the cam rotates, before a switched-on contact elastic slice is switched off, the other corresponding contact elastic slice has been switched on, and by adding a middle state of one selection switch in the rotation process, signal interruption does not occur in the switching process. The switching between contacts without disturbance is realized by the selection switch. The selection switch has advantages of simple structure, high reliability, and small installation volume.
Description
Technical field
The utility model relates to the Electrical Control Technology of metallurgy industry, relates in particular to the selector switch that a kind of unperturbed switches.
Background technology
In the existing selector switch; Can produce the time difference between the signal from a kind of state to the handoff procedure other a kind of state, after promptly one of them state broke off, a kind of in addition state was just closed; So in the middle of this handoff procedure, can cause the controlled device dead electricity.And the operator to switch the purpose of this state might not be to let equipment stop, so cause misoperation.Operatively point selection switch on the control box of for example in metallurgy industry, using always, in transfer process concentrated and two states on the spot, controlled device can stop because of the signal time difference in the stateful switchover process.
Summary of the invention
In view of this, the main purpose of the utility model is to provide a kind of selector switch of unperturbed switching, can eliminate from a kind of state and switch to " time difference " phenomenon the another kind of state procedure, is implemented in unperturbed switching between each contact.
For achieving the above object, the technical scheme of the utility model is achieved in that
The selector switch that a kind of unperturbed switches comprises handle, installation panel and pedestal; Also comprise the handle that links to each other with the metal rotation axis, be set in the cam on the said metal rotation axis, and two slide bars that connect with said cam respectively, the control assembly that said slide bar carries out the open and close action as the said switch of control; When needs conversion selecting switch state, rotate said handle and drive the rotation of metal rotation axis, when cam during with the left and right rotation of rotation axis; Can make two slide bars be in the groove simultaneously for some time; Make said selector switch be in simultaneously before the conversion with conversion after the middle transition state, when said selector switch continues left or to the right to slide, one of them slide bar skids off groove; The state of contact system that then skids off the slide bar place of groove changes, and accomplishes the state exchange of selector switch.
Wherein, said selector switch also comprises navigation system, and this navigation system is divided into upper semisection and lower semisection two parts, is provided with mechanical stop limiter between the upper semisection of said navigation system and the handle; Also be provided with mechanical stop limiter between the lower semisection of said navigation system and the metal rotation axis.
Said metal rotation axis is connected with said cam in pedestal.
Said installation panel adopts the screw thread mode that spins, and links to each other with the upper semisection of said navigation system.
The lower semisection of said navigation system is used for fixing the pedestal of the cam of contact system, and said contact system and said cam all are enclosed in the pedestal.
The selector switch that the unperturbed that the utility model provided switches through changing the profile of cam, enlarges the area of groove; Make cam in rotation axis left rotation and right rotation process; Two slide bars are in the groove for some time simultaneously, and at this moment (like Fig. 3) appears in the two states of selector switch simultaneously, and selector switch continues to slide left or to the right; One of them slide bar skids off groove; The state of contact system that skids off the slide bar place of groove changes, and accomplishes the state exchange of selector switch at last, thereby has eliminated " time difference " phenomenon in transfer process.The selector switch of the utility model except have can be between each contact the characteristics switched of unperturbed, also have advantage simple in structure, that reliability is high and installation volume is little.

Embodiment
Embodiment below in conjunction with accompanying drawing and the utility model does further detailed explanation to the selector switch of the utility model.
Like the described unperturbed selector switch of Fig. 1～Fig. 4, handle 1 links to each other with the metal rotation axis, is provided with mechanical stop limiter between the upper semisection 3 of handle 1 and navigation system; To prevent that handle 1 from excessively being rotated in rotary course; Also be provided with mechanical stop limiter between the upper semisection 3 of metal rotation axis and navigation system, in removal handle, rotation axis be shifted preventing; Influence the effect that is connected of rotation axis and cam, rotation axis is connected with cam in pedestal 5.Installation panel 2 adopts thread connecting mode, links to each other with the upper semisection 3 of navigation system.Said navigation system is made up of upper semisection 3 and lower semisection 4.The upper semisection 3 of said navigation system is accomplished the whole installation and removal of selector switch with installation panel 2; The lower semisection 4 of navigation system mainly be used for fixing contact system (mainly comprise slide bar, with the slide bar common switch block that constitutes etc. that connects; As; Can be the part of circuit or control device) the pedestal of cam; Contact system and cam all are enclosed in the pedestal 5, and on the surface of pedestal 5 binding post are set (inside at the selector switch of the utility model links to each other with the contact point of the switch of controlling through the action of slide bar separately).
Its course of work shown in Fig. 2～Fig. 4 (section schematic top plan view), when needs conversion selecting switch state, rotary handle; Then can drive the rotation of metal rotation axis; When cam during with the left and right rotation of rotation axis, two slide bars are in the groove for some time simultaneously, at this moment the two states of selector switch occurs simultaneously; Be that said selector switch is in before the conversion and the middle transition state after the conversion (this moment, two slide bars connected with said cam simultaneously) simultaneously; Selector switch continues left or slides to the right, and one of them slide bar skids off groove, and the state of contact system that then skids off the slide bar place of groove changes; Accomplish the state exchange of selector switch at last, guaranteed in state conversion process, " time difference " phenomenon can not occur with this.
The above is merely the preferred embodiment of the utility model, is not the protection range that is used to limit the utility model.
