Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adapter device for connecting a breaker on /

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adapter device for connecting a breaker on / off switch and a switch operation handle, and more particularly to a slide contact type in which alignment is smoothly performed while approaching an entry position, So that the deflection of the shaft can be minimized. In particular, even if the shaft is deflected, the engagement and disengagement between the engaging projections of the shaft and the engaging grooves of the switch operating handle can be stably and smoothly performed.

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 Patent Document 1, the length of the shaft mentioned above also becomes longer according to the internal structure and scale of the switchboard. As the length of the shaft becomes longer, the amount of deflection of one end of the shaft coupled with the operating portion gradually increases as the length of the shaft becomes longer. As a result, not only the engaging groove of the first housing of the operating portion but also the engaging projection of the shaft There is a problem that the joining positions are not matched with each other due to the state of completely deviating from the joining position, so that the joining is not fundamentally achieved at all.

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.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Example 1]

The breaker on / off switch 14, which is coupled to the breaker 10 to move the breaker on / off button 12 to switch modes, as shown in FIGS. 1A to 3B, is connected to the hinge hole 18 The hinge ribs 20 are formed at the center of the upper surface.

A rotating body 22 is rotatably provided in the hinge hole 18. An engaging projection 24 is formed on the upper surface of the rotating body 22 so as to protrude in a cruciform arrangement. The rotary body 22 is connected to various connection parts (not shown) provided inside the circuit breaker on-off switch 14.

Accordingly, the breaker on / off button 12 is switched to the on mode or the off mode according to the rotation direction of the rotating body 22. At this time, various connection parts provided inside the breaker on- The coupling relationship in which the breaker on / off button 12 is switched to the on mode or the off mode is the same as that of the various connecting parts connected to the rotating body and the rotating body described in Korean Patent Publication No. 2014-008772 . Furthermore, since various connecting parts provided inside the circuit breaker on / off switch 14 are not for achieving the object of the present invention, a detailed description thereof will be omitted.

The present invention is connected to a structure in which a breaker on / off switch 14 corresponding to the operation section and a switch operation handle 28 having a key knob 26 corresponding to the operation section are connected as in Patent Document 1, There is shown a configuration of an adapter device 30 that interlocks the rotary body 22 and the key knob 26 with each other.

Specifically, the adapter device 30 includes a rotating adapter 32, a slide adapter 34, a shaft 38 provided with an engaging projection 36, and a cover 40.

First, a guide space 42 is formed on one side of the tilting adapter 32 so that the tilting adapter 32 can take an engagement shape in which the hinge rib 20 is received. The guide space 42 is formed with a rotation engaging portion 46 including an engaging groove 44 rotatably inserted into the hinge hole 18 and formed in the same arrangement as the engaging protrusion 24, .

Therefore, when the rotary coupling portion 46 formed on one side of the rotary adapter 32 is engaged with the hinge hole 18, the coupling groove 44 formed in the rotary coupling portion 46 of the rotary adapter 32 And the engaging projections 24 of the entire body 22 are engaged in the interference fit type.

That is, since the coupling structure between the coupling groove 44 and the coupling protrusions 24 of the rotating body 22 is a coupling type in which the face-to-face is in close contact with each other, the assembly tolerance due to the coupling hardly occurs. So that the deflection of the pivoting adapter 32 hardly occurs.

A slide engagement portion 50 including a first slide groove 48 is formed on the other side of the rotation adapter 32 corresponding to the rotation engagement portion 46. The slide adapter 34 is slidably engaged with the first slide groove 48 thus formed.

The slide adapter 34 is formed with a first slide protrusion 52 at a lower portion thereof so as to be slidably engaged with the first slide groove 48.

A first engaging portion 54 is formed on both sides of the first slide groove 48 to engage the first slide protrusion 52 with the first slide groove 48, A first latching groove 56 into which the first latching portion 54 is slidably engaged is formed on both sides of the first latching portion 52.

The second slide groove 60 is formed in the upper portion of the slide adapter 34 in such a manner that the second latching portions 58 are bent at both ends of the slide adapter 34.

The second slide groove (60) is formed in a direction perpendicular to the direction of the first slide groove (48).

The shaft 38 having the engaging projection 36 is slidably engaged with the second slide groove 60 and the engaging projection 36 is engaged with the engaging projection 36 for the slide engagement between the second slide groove 60 and the shaft 38. [ And the second slide protrusion 62 is formed on the corresponding surface of the shaft 38. [

Therefore, the slide adapter 34 is caused to slide along the first slide groove 48 by the above-described coupling structure, and the shaft 38 is caused to slide along the second slide groove 60. That is, the slide adapter 34 and the shaft 38 are slidably moved in the direction intersecting with each other.

The cover 40 is coupled to the slide adapter 34 of the rotation adapter 34 so as to surround the outer surface of the slide adapter 34. The inner surface of the cover 40 and the slide adapter 34, The second slide protrusion 62 prevents the slide adapter 34 from completely moving due to the slide-over movement without interfering with the slide movement by the clearance space 66 as well as the slide adapter 34 .

In addition, the cover 40 functions to completely cover the slide engagement portion of the slide adapter 34 to improve the aesthetics of the external appearance (see FIGS. 1B, 3A, and 3B).

Particularly, the cover 40 and the slide engaging portion 50 are formed with a binding means 68 having a detachable coupling structure. It is preferable that the coupling starting end 68 is formed by a hook-shaped coupling protrusion 70 and a coupling groove 72 to which the coupling protrusion 70 can be coupled, It is not necessary to have a structure in the form of the protrusion 70 and the engaging groove 72 and any binding means and structure may be used provided that the cover 40 can be easily fixed and separated.

4A and 4B show a state in which the engagement projection 36 of the adapter device 30 enters the switch operation handle 28 assuming that the entry position of the engagement projection 36 is not aligned. 4A shows a state in which the engaging projection 36 is in contact with the entry inducing slope 74, and in FIG. 4B, the engaging projection 36 is seen in the engaging groove 76. As shown in FIG.

As described above, when the adapter device 30 according to the present invention is used, the interference fit between the engagement groove 44 of the rotation adapter 32 and the engagement projection 24 of the rotation body 22, The coupling clearance between the coupling groove 44 and the coupling projection 24 is not formed, so that deflection, swinging or flow of the rotary adapter 32 does not occur at all.

The slide adapter 34 is coupled to the first slide groove 48 and the first slide protrusion 52 so that the slide adapter 34 is slidable between the first slide groove 48 and the first slide protrusion 52, 2 and the slide projections 62 are engaged with each other, the shaft 38 is deflected and moved in position by the minimum tolerance for tolerance, that is, minimum assembling tolerance.

However, since the sliding engagement is a face-to-face contact type slide moving structure, the sagging amount is not large and is within the permissible range, so that sagging or positional displacement does not occur to such an extent that the engaging projection 24 of the shaft 38 deviates from the entrance inducing slope 74 .

For example, when the opening / closing panel is closed as in the background art, a state in which the engaging projection 36 of the shaft 38 comes off the engaging groove 76 of the switch operation handle 28, that is, 4A and 4B, the engaging projection 36 of the shaft 38 rides on the surface in contact with the entry inducing sloping surface 74 and is directed toward the engaging groove 76 I want to move.

In this case, when the entering direction in which the engaging projection 36 of the shaft 38 moves toward the engaging groove 76 is, for example, an upward, downward direction, leftward or rightward direction, the first and second slide projections 52, 62 are slid along the corresponding first and second slide grooves 48 and 60 respectively so that the engagement protrusions 36 of the shaft 38 can slide without any strong contact resistance with the entry slope guide surface 74 The alignment with respect to the entering direction and the entering position in which the inclined guide surface 74 can smoothly ride into the engaging groove 76 is naturally matched.

In this way, the entry alignment of the shaft 38 with respect to the engaging projection 36 is smoothly and naturally aligned with the engaging groove 76, so that smooth engagement and disengagement is achieved. In addition, it is possible to prevent the breakage of the switch operation handle 28 due to the impact and the jam, as well as providing convenience for the operation.

A first latching portion 102 is formed on both sides of the first slide groove 96 so that the first slide projection 100 is engaged with the first slide groove 96, A first latching groove 104 is formed on both sides of the first latching portion 100 so that the first latching portion 102 is slidably engaged.

A second slide groove 108 is formed in the upper portion of the slide adapter 98 in such a manner that the second latching portions 106 are bent at both ends of the slide adapter 98.

The second slide groove (108) is formed in a direction perpendicular to the direction of the first slide groove (96).

A cover 112 is coupled to the connection adapter 84 so as to surround the outer surface of the slide adapter 98. A clearance space 66 is formed between the inner surface of the cover 112 and the slide adapter 98 So that the second slide protrusion 110 as well as the slide adapter 98 does not interfere with the slide movement by the clearance space 66, thereby preventing complete departure due to slideover movement.
