Description
Technical field
The utility model is related to power switch technical fields, and in particular to a kind of key displacement chuck and high-current supply are opened
It closes.
Background technology
According to the market demand, to high-current supply switching requirements, its is with the 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 there are two types of the technical solutions of above-mentioned requirements：
First, switching between key and housing increases connect band, this connect band one end is sleeved on housing, and one end is buckled in handle
On, it is allowed to haul without losing because being connected band in "Off" state lower handle.But shortcoming is, when switch is in "Off" state
When do not want handle can be removed, this point but can not meet.Chinese patent literature CN202948869U（Publication date 2013
May 22 in year）In disclose anti-falling piece and fixing sleeve, fixing sleeve is used for connecting valve main body and switch key to prevent key from taking off
It falls, the as above-mentioned method for increasing connect band between switch key and housing.
2nd, on housing increase elastic circlip enable to block key bar, key is made not to be removed, but there are still have with
Lower problem：
1. when upper shell installs clamp spring, because being punched firstly the need of on upper shell, and while punching, to generate clast easy
It falls into inside switch main body, switch performance is caused to fail；
2. when wanting to remove key, borrow tool is needed to unclamp clamp spring, can just remove key, it is time-consuming and laborious；
3. when installing upper handle, shaken hands handle with great strength, the clamp spring easy deformed damaged by stretch bending will when installing again
It cannot play the role of card master key bar.
The switch of switch producer of country production, handle can not achieve in the case where not dismantling housing off status key not
It falls, 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 ribs, key that can 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 ribs are easily worn, and finally make to block the disabler of key bar due to convex ribs are worn.
In order to solve defect of the existing technology, inventor knows about certainly above-mentioned technology by constantly groping for many years
The basic ideas of problem then by a large amount of experiments repeatedly, overcome the problems, such as that multiple technologies ultimately form the technical side of the present invention
Case.
