Abstract
The utility model relates to a miniature disconnecting switch and mainly solves the problem that the safety of a conventional miniature disconnecting switch is affected as the conventional miniature disconnecting switch does not have an indication function. The miniature disconnecting switch comprises an outer shell, which is provided with a handle, a slide rod, a dynamic contact, a static contact, and a wiring terminal. The static contact is fixed in the lower end of the outer shell. The dynamic contact is fixed on the slide rod. The handle is arranged in the upper end of the outer shell and matched with the slide rod. The handle rotates to push the slide rod to move up and down reciprocally in a linear manner, thereby causing the contacting or disconnecting of the dynamic contact and the static contact. The outer shell is hinged with an indicator. The slide rod moves up and down reciprocally in a linear manner and drives the indicator to rotate around the hinge center through a transmission mechanism. The miniature disconnecting switch adopts the indicator, so that the opening or closing state of the switch can be indicated clearly. Therefore, the safety performance can be improved, and the reliability can be brought to operators and maintenance personnel.
Description
Technical field
The utility model relates to a kind of electric protection device, refers in particular to a kind of small-sized isolating switch.
Background technology
Isolating switch is to use one of maximum a kind of electrical equipment in the complete sets of equipment such as power distributing meter case and distribution system, play the power supply buffer action in circuit, the principles and structure of itself is fairly simple, small-sized isolating switch does not in the market have deixis, in use, can not be unfavorable for the reliability of operation by observing clear and definite circuit in closing a floodgate or gate-dividing state, fail safe is lower.
Summary of the invention
For shortcoming and the weak point that overcomes background technology, the utility model provides a kind of small-sized isolating switch, solves existing small-sized isolating switch owing to not having deixis, makes the affected problem of its fail safe.
The technical solution of the utility model is: a kind of small-sized isolating switch, comprise shell, described shell is provided with handle, the slippage bar, moving contact, fixed contact and binding post, described fixed contact is fixed on the lower end of shell, described moving contact is fixed on the slippage bar, described handle is located at the upper end of shell and is matched with the slippage bar, the upper and lower straight reciprocating motion of described handle rotation promotion slippage bar forms described moving contact and contacts with fixed contact or separate, be hinged with indicating device on described shell, the upper and lower rectilinear motion of described slippage bar also drives described indicating device along its hinged central rotation by transmission mechanism.
Described transmission mechanism comprises push pedal, hairclipper, described push pedal is fixed on the slippage bar, described hairclipper is fixed on the end of push pedal, described indicating device is provided with chute, described hairclipper is through chute, and the upper and lower straight reciprocating motion of described slippage bar forms described indicating device along hinged central rotation by described hairclipper along the chute slippage.
Described push pedal is perpendicular to the side of slippage bar, and described chute is skewed slot.
The utlity model has following beneficial effect: but due to this small-sized isolating switch adopt can with the indicating device of moving contact interlock, can clear and definite indicator cock in closing a floodgate or gate-dividing state, improve security performance, bring reliability to operator and maintainer.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
In figure, shell 1, handle 2, slippage bar 3, moving contact 4, fixed contact 5, binding post 6, indicating device 7, through hole 8, push pedal 9, hairclipper 10, chute 11.
Embodiment
Below for accompanying drawing, embodiment of the present utility model is described further:
Shown in figure, a kind of small-sized isolating switch, comprise shell 1, described shell 1 is provided with handle 2, slippage bar 3, moving contact 4, fixed contact 5 and binding post 6, described fixed contact 5 is fixed on the lower end of shell 1, described moving contact 4 is fixed on slippage bar 3, described handle 2 is located at the upper end of shell 1 and is matched with slippage bar 3, described handle 2 rotate promote the slippage bars Shang Xia 3 straight reciprocating motion form described moving contact 4 and contact or separate with fixed contact 5, be hinged with indicating device 7 in described shell 1, described slippage bar rectilinear motion drive described indicating device 7 along its hinged central rotation by transmission mechanism Shang Xia 3, and described shell 1 is provided with the through hole 8 communicated with described indicating device 7.During use, turning handle, driving slippage bar 3 by handle moves down and makes moving contact on slippage bar 3 contact with the fixed contact of shell lower end to realize closing a floodgate, simultaneously, slippage bar 3 drives by transmission mechanism the change that the indicating device rotation realizes indication, in like manner, driving slippage bar 3 by turning handle moves up and makes moving contact on slippage bar 3 and fixed contact be separated to realize separating brake, realize the variation of indicating device, therefore, because but this small-sized isolating switch adopts indicating device, can clear and definite indicator cock in closing a floodgate or gate-dividing state, improve security performance, bring reliability to operation.
As shown in the figure, described transmission mechanism comprises push pedal 9, hairclipper 10, described push pedal 9 is fixed on slippage bar 3, described hairclipper 10 is fixed on the end of push pedal 9, described indicating device 7 is provided with chute 11, and described hairclipper 10 is through chute 12, described slippage bar Shang Xia 3 straight reciprocating motion form described indicating device 7 along hinged central rotation by described hairclipper 10 along chute 11 slippages, described push pedal 9 is perpendicular to the side of slippage bar 3, and described chute 11 is skewed slot.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
