Description
Technical field
The present invention relates to power switch technical field, and in particular to a kind of key displacement chuck, large-current electric source switch and
Its application method.
Background technology
According to the market demand, to high-current supply switching requirements, it has following functions, when normal " switch " state uses
When key can not fall down, when wanting to remove key, key can be easily removed, and not influence to install again to make
With.
The key switch used now meets that the technical scheme of above-mentioned requirements has two kinds：
First, switching between key and housing increases connect band, and this connect band one end is enclosed on housing, and one end is buckled on handle, is made
In "Off" state lower handle because connected band is hauled without losing.But shortcoming is, when switch is in "Off" state
Wait and do not want handle can be removed, this point but can not meet.Chinese patent literature CN202948869U（Publication date 2013 5
The moon 22）In disclose anti-falling piece and fixed cover, fixed cover is used for connecting valve main body and switch key to prevent key from coming off, i.e.,
For the above-mentioned method for increasing connect band between switch key and housing.
2nd, increase elastic circlip on housing to enable to block key bar, key is not removed, but still have following ask
Topic：
1. when upper shell installs jump ring, because being punched firstly the need of on upper shell, and chip can be produced when punching and easily fallen into
Inside switch main body, switch performance is caused to fail；
2. unclamping jump ring, it is necessary to borrow instrument when wanting to remove key, key can be just removed, is wasted time and energy；
3. when installing upper handle, with great strength handle, the jump ring easy deformed damaged by stretch bending can not when installing again
Play a part of card master key bar.
The switch of country's switch manufacturer production, handle can not realize that off status key is not in the case where not dismantling housing
Drop, key arbitrarily can install and remove function.
External key switch, though the key switch that certain such as German factory uses, which also has, arbitrarily can install and remove work(by handle
Can, but its principle is that have a circle convex tendon, key to stumble key bar after pushing in inner walls to prevent key from coming out,
When wanting to remove key, key is first in "Off" state, key can be removed by pulling at key, but shortcoming is repeatedly to push away
After drawing key, convex tendon is easily worn, and finally makes the disabler of blocking key bar because convex tendon is worn.
In order to solve the defects of prior art is present, inventor knows about certainly above-mentioned technology by constantly groping for many years
The basic ideas of problem, then by experiment repeatedly, multiple technologies problem is overcome to ultimately form technical scheme.
The content of the invention
