Abstract
Description
BACKGROUND OF THE
Generally, a breaker is fixedly installed inside the switchboard, and the on-off switch is detachably connected to the breaker.
Further, a switch operation handle having a key knob is fixedly installed on an opening / closing door for opening / closing the inside of the switchboard.
One end of the connection shaft is coupled to the switch operation handle on the circuit breaker on-off switch, and when the switch cover is opened and closed, the other end of the connection shaft enters the connection groove of the switch operation handle, .
Accordingly, the connection shaft rotates according to the rotation direction of the key operation knob, and the circuit breaker on-off switch is interlocked with the connection shaft in accordance with the interlocking rotation of the connection shaft, Thereby switching the mode.
As an example of the use of the above-described circuit breaker on-off switching switch and switch operating handle, Korean Utility Model Publication No. 20-2011-0010529 (published on November 10, 2011, hereinafter referred to as Patent Document 1) Discloses a configuration in which the operating portion is coupled to the breaker for switching on and off modes of the switch lever of the circuit breaker and the operating portion is provided on the opening and closing panel of the switchboard.
In the above construction, a structure is adopted in which a shaft having a coupling protrusion at one end is rotatably shaft-coupled to a second housing of the operating portion between the operating portion and the operating portion so as to be detachably coupled to the operating portion.
In this case, when the length of the shaft is short, even if deflection of the shaft due to the assembly tolerance occurs, the deflection amount is small and the weight of the shaft A large resistance is not given to the rotating phase.
However, as described above, when the deflection of the shaft is largely generated due to the assembly tolerance of the shaft, there is a problem that the coupling protrusion of the shaft is caught from the inside of the operation portion and can not smoothly come out. In order to solve such a problem, there has been a problem that when the physical force is more strongly applied and forced separation is performed, the operating portion is damaged.
On the other hand, when the opening / closing panel is closed in a state where deflection of the shaft is generated due to the assembly tolerance of the shaft, the engaging projection comes into contact with the entrance inducing slope formed around the engaging groove of the first housing. At this time, if the shaft can bend or bend naturally, the shaft can be naturally coupled to the coupling groove. However, since the shaft is made of aluminum material, there is no warping or bending, so that entry into the coupling groove is not smooth .
In order to solve such a problem, there is a problem in that when the coupling protrusion of the shaft is forcefully engaged with the inclined surface for guiding the entrance of the shaft, the periphery of the coupling groove of the first housing is broken.
Furthermore, when the distance between the operating portion and the operating portion is further than the distance shown in
In addition, due to the deflection amount of the shaft generated as described above, the frictional resistance is formed more strongly due to the weight of the shaft in a state where the frictional resistance due to the rotational contact is formed, so that the rotating operation of the shaft is made stiff. There is a problem in that the rotation of the shaft is not smoothly performed and the interlocking operation with respect to the operation portion and the operation portion is not smooth as a whole.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a slide coupling type in which alignment is smoothly performed while the entrance position is detected, Off switch and a switch operation handle, so that the engagement and disengagement between the coupling protrusion of the shaft and the coupling operation groove of the switch operation handle can be stably and smoothly performed even when the switch operation handle is generated.
According to an aspect of the present invention, there is provided a circuit breaker comprising: a circuit breaker on / off switch provided with a circuit breaker, An adapter device connected to a rotating body and a key knob so as to be interlocked with each other, the rotating adapter connected to the rotating body so as to be interlocked with the rotating body; A slide engaging portion formed in the pivoting adapter to include a first slide groove; A slide adapter having a first slide protrusion slidably coupled along the first slide groove; A second slide groove formed on the slide adapter surface corresponding to the first slide groove; And a shaft slidably coupled along the second slide groove and having a coupling protrusion on one surface thereof. The adapter device for connecting the switch on / off switch and the switch operation handle is provided.
In order to achieve the above-mentioned object, the present invention provides a switch-on / off switch which is disposed between a switch operation handle having a key switch and a circuit breaker on / An adapter connected to the rotary body and the key knob for interlocking with each other; A coupling groove formed in the pivoting adapter; A connection shaft having one end inserted into the coupling groove; A connection adapter coupled to the other end of the connection shaft; A first slide groove formed in the connection adapter; A slide adapter having a first slide projection to be slidably engaged along the first slide groove; A second slide groove formed on a surface of the slide adapter corresponding to the first slide groove; And a shaft slidably coupled to the second slide groove and having a coupling protrusion on one surface thereof. The adapter device for connecting the switch on / off switch and the switch operation handle is provided.
As described above, when the adapter device for connecting the circuit breaker on / off switch and the switch operation handle according to the present invention is used, deflection of the shaft can be minimized, and even if deflection occurs, It is possible to expect the effect that the rotation body and the key knob can be interlocked smoothly.
The use of the adapter device for connecting the circuit breaker on / off switching switch and the switch operation handle according to the present invention allows the connection operation of the switch operation handle to be performed without any internal jamming due to sagging, The effect can be expected.
