Description

Technical Field

[0001] The present invention relates to an input / output device, and more specifically, to an input / output device that can be easily coupled and detached from a power distribution frame and coupled to a precise location. Background Technology

[0002] A distribution board is a device that, depending on the system or purpose, transmits electricity received from an external power supply to the load. The distribution board is energized by both the external power supply and the load.

[0003] To prevent potential electrical accidents between external power sources and loads, circuit breakers are typically installed in the distribution panel. These circuit breakers are configured to be energized separately from both the external power source and the load, thereby interrupting them in the event of an abnormal current. This prevents such electrical accidents.

[0004] When performing a current-blocking operation, it may be necessary to replace the circuit breaker's components. Alternatively, it is conceivable that the circuit breaker may need to be disconnected from the distribution panel for maintenance. Therefore, circuit breakers are typically detachably integrated into the distribution panel.

[0005] On the other hand, the size of switchboards and circuit breakers tends to be proportional to their rated capacity. That is, when a larger current flows, the size of the circuit breaker used to block it may also increase. Consequently, the size of the switchboard connected to the circuit breaker may also increase. Therefore, a large force is required to connect or disconnect the circuit breaker from the switchboard.

[0006] However, in the case of traditional switchboards and circuit breakers, the process of connecting and disconnecting circuit breakers is done manually. That is, the process is usually performed by operators. Therefore, the accuracy and efficiency of connecting and disconnecting circuit breakers may be reduced. Furthermore, it is difficult to rule out the possibility of safety accidents when connecting and disconnecting heavy circuit breakers.

[0007] For this purpose, a lead-in / lead-out device is used for introducing and leading in a circuit breaker to or from a distribution panel. The lead-in / lead-out device is configured to introduce or lead in a circuit breaker while being connected to and supported by the distribution panel. Therefore, the lead-in / lead-out device typically includes a first configuration connected to the distribution panel, a second configuration connected to the circuit breaker, and a third configuration for driving the second configuration.

[0008] However, as mentioned above, with the increase in the size and weight of circuit breakers, the size and weight of the input and output devices can also increase to provide the corresponding power. In this case, excessive force is required to integrate the input and output devices into the distribution panel, which may reduce the ease of operation.

[0009] Furthermore, as the weight of the lead-in / lead-out device increases, the difficulty of configuring it to the precise location for connection with the circuit breaker may also increase. In this case, there is a risk that the overall difficulty of the operation of leading and leading the circuit breaker into and out of the distribution panel will increase.

[0010] Korean Patent No. 10-1733705 discloses a distribution panel equipped with a safety device for the introduction and withdrawal of a vacuum circuit breaker. Specifically, the distribution panel disclosed has a locking groove on the bottom surface of a transport vehicle on which the vacuum circuit breaker is mounted, and the locking groove is constrained or released by a horizontal plate mounted on a support, thereby preventing the vacuum circuit breaker from moving arbitrarily.

[0011] However, the existing documents disclose distribution panels equipped with vacuum circuit breaker lead-in and lead-out safety devices that require manual lead-in and lead-out of the vacuum circuit breaker. That is, the existing documents do not propose a scheme for automatically executing the lead-in and lead-out process of the vacuum circuit breaker.

[0012] Korean Patent No. 10-1912449 discloses a high-voltage switchboard with a remote locking system. Specifically, it discloses a high-voltage switchboard with a remote locking system that allows circuit breakers to be remotely accessed or introduced into the switchboard.

[0013] However, the high-voltage switchboards disclosed in the existing literature that utilize remote locking systems require the installation of actuators for moving circuit breakers within the switchboard itself. This necessitates the inclusion of additional motors within the complex, multi-faceted high-voltage switchboard, and necessitates additional, complex wiring structures for their control.

[0014] Furthermore, the remote locking systems disclosed in the existing literature are configured to handle complex conditions for moving the circuit breaker. Therefore, precise input of control signals for introducing or withdrawing the circuit breaker is required, making it difficult to smoothly execute the circuit breaker introduction or withdrawal process.

[0015] Korean Patent No. 10-1733705 (May 8, 2017)

[0041] Invention Effects

[0042] According to the above configuration, the introduction and extraction device of the present invention can be easily set up and separated.

[0043] The lead-in and lead-out device is detachably integrated with the distribution frame. The lead-in and lead-out device is detachably integrated with the circuit breaker housed in the distribution frame, allowing the circuit breaker to be brought in or taken out.

[0044] The lead-in / lead-out device includes a power unit that provides power for leading in and leading out the circuit breaker, and a handle unit that is connected to the power unit and the circuit breaker and transmits the generated power. Additionally, the lead-in / lead-out device includes a bracket unit that supports the power unit and is connected to the distribution frame.

[0045] The power unit, handle unit, and bracket unit can be detachably combined with each other. The power unit, handle unit, and bracket unit can also be independently combined with the power distribution frame.

[0046] As an example, the handle can be initially connected to the distribution frame and the circuit breaker housed inside the distribution frame. The bracket can be connected to both the distribution frame and the handle, and the power unit can be connected to both the bracket and the handle. That is, the power unit, circuit breaker, and handle constituting the input / output device can move independently and connect to the distribution frame and other components.

[0047] Therefore, the amount of force required to connect or disconnect the lead-in device from the distribution frame can be reduced. Consequently, the installation and disconnection of the lead-in device can be made easier.

[0048] Furthermore, according to the aforementioned configuration, the introduction and extraction device of this embodiment of the invention can be easily moved to the desired position.

[0049] As described above, the various components of the lead-in / lead-out device can be separated and individually integrated with the distribution frame or circuit breaker. Therefore, the lead-in / lead-out device can be easily integrated with the distribution frame.

[0050] In one embodiment, the bracket portion may be assembled with the power distribution frame before the power unit. The bracket portion includes a guide profile extending in one direction. A guide groove extending in said one direction is formed in the outer periphery of the guide profile.

[0051] The power unit includes a motor component that provides power and a power bracket that supports it. The power bracket includes a bracket housing space that serves as a space for accommodating guide profiles. The bracket housing space is defined by a support bracket and a connecting bracket.

[0052] The bracket includes a first bracket plate that surrounds the guide profile from one side and a second bracket plate that is continuous with the first bracket plate and surrounds the guide profile from the other side. The second bracket plate is provided with a guide rail that is slidably accommodated in a guide groove.

[0053] If the guide profile is accommodated in the bracket accommodating space, the guide rail is also accommodated in the guide groove. Due to the combination of the guide rail and the guide groove, the power unit can move in one direction and prevent swaying in the other direction.

[0054] Therefore, the power unit, which is connected to the bracket, can be easily moved to a preset position.

[0055] Furthermore, according to the aforementioned configuration, the lead-in and lead-out device of this embodiment of the invention can be configured at a precise location.

[0056] A fixing hole is formed on one side of the profile body. The fixing hole is recessed on said side of the profile body. At this time, the fixing hole can be positioned to correspond to the distance that the power unit moves toward the power distribution frame in said direction.

[0057] The power bracket includes a power stop. The power stop is extendably inserted into the fixing hole at a position overlapping with it. In one embodiment, the power stop extends through and engages in a stop engagement hole formed in the first bracket plate.

[0058] In one embodiment, the power stop may have an elastic member such as a spring. The elastic member applies an elastic force to the power stop in the direction toward said side of the profile body. When the power unit moves, the power stop can remain in contact with said side of the profile body.

[0059] If the power stop is arranged overlapping the fixing hole, the power stop is inserted into the fixing hole under the action of the elastic force. This restricts further movement of the power unit in the aforementioned direction.

[0060] Therefore, if the power unit moves to the preset position, the power stop is accommodated in the fixing hole, thereby limiting further movement. Thus, the power unit can be positioned accurately.

[0061] Furthermore, according to the aforementioned configuration, the lead-in / lead-out device of this embodiment can be easily fixed to the configured position.

[0062] A mating groove is formed on one side of the profile body. The mating groove extends along the aforementioned direction and is recessed on the aforementioned side of the profile body.

[0063] The power bracket includes a power retaining member that can be extended and inserted into the mating groove. If the aforementioned power stop is received in the fixing hole, the power retaining member can be operated and inserted into the mating groove. If the power retaining member moves a predetermined length, one side of the profile body surrounding the mating groove is pressed by the power retaining member.

[0064] Therefore, the power unit that has moved to the preset position can be stably held in the corresponding position by the power fixing member.

[0065] Furthermore, according to the above configuration, the lead-in / lead-out device of the present invention can easily perform the lead-in / lead-out process of the circuit breaker.

[0066] As mentioned above, the power for bringing in and out the circuit breaker can be provided by a motor component. That is, no human power is required to move the circuit breaker.

[0067] Therefore, not only can the installation and disconnection of the lead-in and lead-out devices be easily performed, but the lead-in and lead-out processes of the circuit breaker can also be easily performed.

[0068] Another object of the present invention is to provide an inlet / outlet device having a structure that facilitates the maintenance of circuit breakers.

[0069] As described above, the bracket, power unit, and handle unit constituting the inlet / outlet device can be detachably combined. In the event of maintenance of the inlet / outlet device, only the corresponding components can be detached to perform the required work.

[0070] Therefore, maintenance of the lead-in and lead-out devices can be easily performed, and the required costs can be saved.

[0071] The effects of the present invention are not limited to those described above, but should be understood to include all effects that can be derived from the invention's composition as described in the detailed description or claims. Attached Figure Description

Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figures 11 to 12 as well as Figure 18 We can understand this using the coordinate system shown in the diagram.

[0098] Reference Figures 1 to 2 The diagram illustrates the combined and separated states of the lead-in / lead-out device 1 and the power distribution frame 2 according to an embodiment of the present invention. The lead-in / lead-out device 1 can be combined with one side of the power distribution frame 2, i.e., the front side in the illustrated embodiment.

[0099] The lead-in / lead-out device 1 can extend through one side of the power distribution frame 2 and be combined with a circuit breaker (not shown) housed inside the power distribution frame 2. The lead-in / lead-out device 1 can be used to bring the circuit breaker (not shown) into or out of the power distribution frame 2 while it is combined with and supported by the power distribution frame 2.

Additionally, the lead-in / lead-out device 1 can be detachably connected to a circuit breaker (not shown) housed inside the power distribution frame 2. In the illustrated embodiment, the lead-in / lead-out device 1 moves rearward to connect with the power distribution frame 2 and moves forward to separate from the power distribution frame 2.

[0101] In particular, the various components of the lead-in / lead-out device 1 in this embodiment of the invention can be at least partially detachably combined with each other. Due to the configuration described above, the various components of the lead-in / lead-out device 1 can be sequentially combined with or separated from the power distribution frame 2.

[0102] The following will describe the power distribution frame 2 first, and then describe the incoming and outgoing device 1.

The circuit breaker (not shown) housed in the distribution frame 2 can be energizedly connected to an external power source (not shown) or load (not shown). The circuit breaker (not shown) is housed in the distribution frame 2 and is not exposed to the outside. This prevents safety accidents caused by high-voltage current energized to the circuit breaker (not shown).

[0104] The distribution frame 2 can be any shape capable of accommodating a circuit breaker (not shown). In the illustrated embodiment, the distribution frame 2 is a three-dimensional shape having a length in the front-to-back direction, a width in the left-to-right direction, and a height in the top-to-bottom direction.

[0105] The power distribution frame 2 is detachably connected to the inlet / outlet device 1. As shown in the figure, the power distribution frame 2 is formed to have a larger volume than the inlet / outlet device 1, so the connection and separation can be performed as the inlet / outlet device 1 moves.

[0107] The main body 2a of the power distribution frame forms part of the outer shape of the power distribution frame 2. The main body 2a of the power distribution frame at least partially surrounds the power distribution frame space 2b formed therein. In the illustrated embodiment, the main body 2a of the power distribution frame forms the rear, left, right, upper, and lower sides of the power distribution frame 2. The main body 2a of the power distribution frame surrounds the power distribution frame space 2b from the rear, left, right, upper, and lower sides.

[0108] The main body 2a of the power distribution frame is combined with the power distribution board 2c. In the illustrated embodiment, the main body 2a of the power distribution frame and the power distribution board 2c are detachably combined. Alternatively, the power distribution board 2c can be rotatably combined with the main body 2a of the power distribution frame.

The inlet / outlet device cover member 2e is rotatably coupled to the inlet / outlet device coupling portion 2d. The inlet / outlet device cover member 2e can be rotatably disposed with one side centered on the radial direction of the inlet / outlet device coupling portion 2d.

[0121] The distribution frame handle 2f is offset to one side of the width direction of the distribution board 2c, i.e., the right side in the illustrated embodiment. The distribution frame handle 2f is the part gripped to move the distribution board 2c, thus opening or closing the distribution frame space 2b. The operator grips the distribution frame handle 2f and applies external force, thereby moving the distribution board 2c.

[0122] Reference Figures 5 to 18 The diagram illustrates an inlet / outlet device 1 according to an embodiment of the present invention. The inlet / outlet device 1 is detachably connected to the distribution frame 2. Alternatively, the inlet / outlet device 1 can also be detachably connected to a circuit breaker (not shown) housed in or to be housed in the distribution frame 2. The inlet / outlet device 1 allows the circuit breaker (not shown) to move in the direction of being housed in or led out from the distribution frame 2.

[0123] The lead-out device 1 can be electrically connected to an external power source (not shown) and a control unit (not shown). The power and control signals used to operate the power unit 20 (described later) can be transmitted from the external power source (not shown) and the control unit (not shown).

[0124] The lead-in / lead-out device 1 is combined with the power distribution frame 2. Specifically, a portion of the lead-in / lead-out device 1 is combined with the power distribution board 2c, and other components of the lead-in / lead-out device 1 are combined with the lead-in / lead-out device connection portion 2d.

[0125] In the illustrated embodiment, the lead-in / lead-out device 1 includes a bracket portion 10, a power unit 20, and a handle portion 30. At this time, the handle portion 30, the bracket portion 10, and the power unit 20 are respectively provided from the power distribution frame 2. That is, the power unit 20, the bracket portion 10, and the handle portion 30 are arranged in a direction from the front side to the rear side.

[0126] like Figure 6 As shown, the bracket portion 10, power unit 20, and handle portion 30 of the lead-in / lead-out device 1 in this embodiment of the invention can be detachably coupled to each other. Therefore, the bracket portion 10, power unit 20, and handle portion 30 can be coupled to the power distribution frame 2 in the detached state.

[0127] Therefore, compared to the case where the lead-in / lead-out device 1 is integrally formed and combined with the power distribution frame 2, the amount of force required for the connection is reduced, thereby improving workability. Thus, not only can the lead-in / lead-out device 1 be combined with the power distribution frame 2 with less force, but the connection positions of the lead-in / lead-out device 1 and the power distribution frame 2 can also be accurately matched.

[0128] Furthermore, as described later, the lead-in / lead-out device 1 of this embodiment of the invention can accurately and easily combine the bracket portion 10, the power portion 20, and the handle portion 30, which are detachably configured from each other. Therefore, the assembly process of the lead-in / lead-out device 1 can be easily performed, and the combination of each component can be firmly formed.

[0192] The guide profile 320 is combined with the bracket body 100. Specifically, the guide profile 320 is combined with and supported by the limiting plate 130. As described above, the limiting plate 130 includes a first limiting plate 131 and a second limiting plate 132. The guide profile 320 is located between the first limiting plate 131 and the second limiting plate 132, and is combined with the first limiting plate 131 and the second limiting plate 132 respectively.

[0193] The guide profile 320 extends in the direction in which the lead-in / lead-out device 1 engages with the power distribution frame 2 or in the direction in which it separates from the power distribution frame 2. In the illustrated embodiment, the guide profile 320 extends in the front-to-back direction.

[0194] In the illustrated embodiment, the guide profile 320 includes a profile body 321, a guide groove 322, a connecting groove 323, and a fixing hole 324.

[0195] The profile body 321 constitutes the main body of the guide profile 320. A guide groove 322, a connecting groove 323, and a fixing hole 324 are formed in the profile body 321.

[0196] The profile body 321 is combined with the limiting plate 130. The profile body 321 is located between the first limiting plate 131 and the second limiting plate 132, and is combined with the first limiting plate 131 and the second limiting plate 132 respectively.

[0197] The profile body 321 extends along the direction of engagement and disengagement of the power unit 20, i.e., the front-rear direction in the illustrated embodiment. One end of the profile body 321 extending in the illustrated embodiment, i.e., the front end in the illustrated embodiment, protrudes outward. The other end of the profile body 321 extending in the illustrated embodiment, i.e., the rear end in the illustrated embodiment, engages with the limiting plate 130.

[0198] The profile body 321 can be a shape corresponding to the shape of the power bracket 600 provided in the power unit 20. In the illustrated embodiment, the profile body 321 is a polygonal prism shape having a width in the left-right direction, a height in the up-down direction, and a length in the front-back direction.

[0199] At this time, the width of the profile body 321 can be formed to be less than or equal to the width of the bracket receiving space 623 of the power unit 20. In other words, the width of the profile body 321 can be formed to be less than or equal to the distance between the pair of second bracket plates 622 (see reference). Figure 12 ).

[0200] Furthermore, the height of the profile body 321 can be set to be less than or equal to the width of the bracket accommodating space 623. In other words, the height of the profile body 321 can be set to be less than or equal to the distance between the first support bracket 611 and the first bracket plate 621 (see reference). Figure 12 ).

[0201] Guide grooves 322 are formed on each side of the profile body 321 in the width direction, namely the left and right sides in the illustrated embodiment.

[0202] The guide groove 322 is configured to guide the movement of the power unit 20, which is coupled to the profile body 321. Due to the guide groove 322, the swaying of the power unit 20 in another direction can be minimized, and the power unit 20 can move stably along the extension direction of the profile body 321, that is, the front-back direction in the illustrated embodiment.

[0203] The guide groove 322 engages with the guide rail 630 provided on the power unit 20. The guide groove 322 supports the guide rail 630 so that it can slide.

[0204] The guide groove 322 is recessed in the surface of the profile body 321. The guide groove 322 extends along the extension direction of the profile body 321. There is a pair of guide grooves 322, which can be formed on different surfaces of the profile body 321 respectively.

[0205] In the illustrated embodiment, there is a pair of guide grooves 322, located on the left and right sides of the profile body 321, respectively. The pair of guide grooves 322 extend along the extension direction of the profile body 321, i.e., the front-to-back direction.

[0206] The guide grooves 322 are open at their ends in the extending direction, allowing the guide rails 630 to be accommodated and extended. A pair of guide grooves 322 support a pair of guide rails 630 so that they can slide separately.

[0207] The guide groove 322 can be formed into a shape corresponding to the shape of the guide rail 630. At this time, the guide groove 322 can be a shape that can engage or disengage with the guide rail 630 in the direction in which the power unit 20 engages or disengages with the bracket unit 10, but prevents engagement or disengagement in the other direction.

[0208] In the illustrated embodiment, the guide groove 322 is formed with a concave-convex cross-section where the height of the inner portion in the width direction is longer than the height of the outer portion. The shape of the guide groove 322 can be changed according to the shape of the guide rail 630.

[0209] The engagement groove 323 is the part that engages with the power fixing member 640 provided on the power unit 20. The core (seam, not marked) provided on the power fixing member 640 is inserted into the engagement groove 323. If the core (not marked) of the power fixing member 640 is inserted and applies pressure to the profile body 321, the relative position of the power unit 20 and the bracket part 10 is fixed, thereby restricting further movement of the power unit 20.

[0210] A groove 323 is recessed into the surface of the profile body 321. The groove 323 extends along the extension direction of the profile body 321. There are multiple grooves 323, which can be formed on the surface of the profile body 321.

[0211] In the illustrated embodiment, there is a pair of mating grooves 323 located on the upper side of the profile body 321. The pair of mating grooves 323 are spaced apart along the width direction of the profile body 321, i.e., in the left-right direction. A pair of power fixing members 640 are respectively extended and accommodated in the pair of mating grooves 323.

[0212] A pair of mating grooves 323 extend along the length direction of the profile body 321, i.e., the front-to-back direction. Each end of the mating groove 323 is open in the extension direction. The power unit 20 can move along the mating groove 323 while the power fixing member 640 is at least partially accommodated in the mating groove 323.

[0213] The number and configuration of the connecting slots 323 can be changed according to the number and configuration of the power fixing components 640.

[0214] A fixing hole 324 is provided between a pair of mating grooves 323.

[0215] The power stop 650, provided in the power unit 20, can be extended and inserted into the fixing hole 324. When the power stop 650 is inserted into the fixing hole 324, further movement of the power unit 20 along the extension direction of the profile body 321, i.e., the front-to-back direction, is restricted. Then, if the power fixing member 640 is operated and the core (not marked) is inserted into the mating groove 323, the position of the power unit 20 can be fixed.

[0216] A fixing hole 324 is formed through or recessed on one side of the profile body 321. In this case, the fixing hole 324 can be formed on the surface formed by the mating groove 323.

With the guide profile 320 contained in the bracket receiving space 623, the power unit 20 can move in the direction facing the power distribution frame 2 or in the opposite direction, i.e., the front side or the rear side.

[0293] The bracket receiving space 623 can be formed corresponding to the shape of the guide profile 320. In the illustrated embodiment, the bracket receiving space 623 is formed to have a length in the left-right direction, a width in the front-back direction, and a height in the vertical direction. At this time, as described above, the length of the bracket receiving space 623 in each direction can be formed to be less than or equal to the length of the guide profile 320 in each direction.

[0294] The bracket receiving space 623 is defined by a first support bracket 611, a first bracket plate 621, and a second bracket plate 622. Each side of the bracket receiving space 623 in the width direction, i.e., the front and rear sides in the illustrated embodiment, is open.

[0301] The stop engagement hole 625 can be formed correspondingly to the shape of the power stop 650. In the illustrated embodiment, the stop engagement hole 6250 is formed as a space in the shape of a circular plate with a circular cross-section and a thickness in the vertical direction.

[0302] The stop member engagement hole 625 can be arranged adjacent to the center of the first bracket plate 621. In other words, the distances to each vertex of the first bracket plate 621 can be the same, with the stop member engagement hole 625 as a reference. At this time, if the power unit 20 moves to the preset position of the bracket part 10, the stop member engagement hole 625 can be located vertically above the fixing hole 324.

[0303] The guide rail 630 is movably inserted into the guide groove 322. In one embodiment, the guide rail 630 can be slidably inserted into the guide groove 322. In the illustrated embodiment, the guide rail 630 is movably inserted into the guide groove 322 along the extension direction of the guide profile 320, i.e., in the front-to-back direction.

[0304] The movement of the guide rail 630 inserted into the guide groove 322 in directions other than the direction of movement, namely the left-right and up-down directions in the illustrated embodiment, is restricted. Therefore, the power unit 20 can move along the extension direction of the guide profile 320, i.e., the front-back direction, and is prevented from wobbling in the left-right or up-down directions.

[0305] As a result, the movement of the power unit 20 relative to the bracket unit 10 can be carried out stably.

[0306] The guide rail 630 can be of any shape that inserts into the guide groove 322 and prevents wobbling in the vertical or horizontal direction. In the illustrated embodiment, the guide rail 630 is formed such that the height of the inner portion in the width direction is longer than the height of the middle portion in the width direction. The shape of the guide rail 630 can be changed accordingly to match the shape of the guide groove 322.

[0307] The guide rail 630 is engaged with the second bracket plate 622. The guide rail 630 is located on the inner surface of the second bracket plate 622 facing the bracket receiving space 623, i.e., in the thickness direction. The guide rail 630 is located in the bracket receiving space 623.

[0308] There may be a plurality of guide rails 630. The plurality of guide rails 630 may be spaced apart from each other and each engage with a plurality of second bracket plates 622. In the illustrated embodiment, there is a pair of guide rails 630, each located on the inner surface of a pair of second bracket plates 622. The pair of guide rails 630 are spaced apart from each other along the length of the bracket receiving space 623, i.e., in the left-right direction in the illustrated embodiment.

[0309] The number and configuration of guide rails 630 can be changed according to the number and configuration of guide slots 322.

[0310] The power fixing member 640 can be extended and accommodated in the mating groove 323. If the power fixing member 640 is fully accommodated in the mating groove 323, the power fixing member 640 applies pressure to the surface of the profile body 321 surrounding the mating groove 323. As a result, the movement of the power unit 20 can be restricted and fixed in the corresponding position.

[0311] The power-fixing member 640 is engaged with the first bracket plate 621. Specifically, the power-fixing member 640 is engaged through the fixing member engagement hole 624 formed through the first bracket plate 621.

[0312] The power-locking member 640 engages with the first bracket plate 621 to be movable in the direction facing the engagement groove 323 and in the opposite direction, i.e., the upper and lower sides in the illustrated embodiment. Alternatively, the power-locking member 640 can remain in a movable state. In one embodiment, the power-locking member 640 may be formed in the shape of a screw and threadedly engaged with the first bracket plate 621.

[0313] The power-locking member 640 can have any shape that is received in the engagement groove 323 and can apply pressure to the guide profile 320. In the illustrated embodiment, the power-locking member 640 includes a core member that extends vertically and passes through the fixing member engagement hole 624 and applies pressure to the guide profile 320, and a handle member that engages with the upper end of the core member and is located on the upper side of the first bracket plate 621.

[0314] In the embodiment described, the operator can adjust the vertical position of the core component by rotating or pressing the handle component.

[0315] There may be a plurality of dynamic fixing members 640. The plurality of dynamic fixing members 640 may be movably connected through at least one of the plurality of fixing member connection holes 624. In the illustrated embodiment, the dynamic fixing member 640 has a pair of fixing member connection holes 624 respectively connected through a pair of fixing member connection holes 624 located on the front right side and the rear left side.

[0316] In either case, as long as the dynamic fixing member 640 is located vertically above the mating groove 323, it is acceptable.

[0317] A power stop 650 is provided between a pair of power-fixed members 640.

[0318] The power stop 650 can be extended and received in the fixing hole 324. If the power stop 650 is received in the fixing hole 324, the movement of the power unit 20 can be restricted and fixed in the corresponding position.

[0319] The power stop 650 is engaged with the first bracket plate 621. Specifically, the power stop 650 is engaged through the stop engagement hole 625 formed through the first bracket plate 621.

[0320] The power stop 650 engages with the first bracket plate 621 to be movable in the direction facing the fixing hole 324 and in the opposite direction, i.e., the upper and lower sides in the illustrated embodiment. In this case, the power stop 650 can move in the direction facing the fixing hole 324 without additional external force, or require an external force to move in the direction opposite to the fixing hole 324.

[0321] In one embodiment, the power stop 650 may include an elastic member such as a spring. The elastic member may be configured to apply an elastic force to the power stop 650 in the direction of the guide profile 320.

[0322] Therefore, when the fixing hole 324 is not located vertically below the power stop 650, the end of the power stop 650 in the extending direction can maintain a state of applying pressure to and contacting the surface of the profile body 321.

[0323] Furthermore, when the fixing hole 324 is located vertically below the power stop 650, the power stop 650 can be accommodated in the fixing hole 324 under the action of the elastic force even without applying additional external force.

[0324] Therefore, if the power unit 20 moves along the guide profile 320, the power stop 650 can first be accommodated in the fixing hole 324 and the position where the power unit 20 needs to be fixed can be identified. Then, if the power fixing member 640 is operated, the power unit 20 can be fixed in the corresponding position.

[0325] Therefore, not only can the position of the power unit 20 be easily identified, but the power unit 20 can also be stably maintained in the preset position.

[0326] Reference Figures 17 to 18 The introduction and extraction device 1 of this embodiment includes a handle portion 30.

[0327] The handle 30 connects the power unit 20 and the circuit breaker (not shown). The handle 30 transmits the power generated by the power unit 20 to the circuit breaker (not shown) and performs the introduction and withdrawal of the circuit breaker (not shown).

[0328] The handle portion 30 is combined with the power distribution frame 2. Specifically, the handle portion 30 passes through the lead-in / lead-out device joint portion 2d provided on the power distribution board 2c, and is combined with the circuit breaker (not shown) housed in the power distribution frame space 2b.

[0329] The handle portion 30 is combined with the bracket portion 10. The handle portion 30 can be rotatably supported on the bracket portion 10.

[0330] The handle 30 is combined with the power unit 20. The handle 30 can receive power generated by the power unit 20.

[0331] The handle portion 30 extends along the direction in which the lead-in / lead-out device 1 is joined or separated from the power distribution frame 2. In the illustrated embodiment, the handle portion 30 extends in the front-to-back direction.

[0332] In the illustrated embodiment, the handle portion 30 includes a shaft member 700.

[0333] The shaft member 700 may be composed of a plurality of parts. One part of the shaft member 700 may be combined with the power unit 20 and supported by the bracket part 10 to be rotatable. Other parts of the shaft member 700 may be combined with the inlet and outlet device connection part 2d of the switchboard 2c and the circuit breaker (not shown).

[0334] In the illustrated embodiment, shaft member 700 includes a first shaft member 710 and a second shaft member 720.

[0335] The first shaft member 710 is a portion of the shaft member 700, that is, the part where the shaft member 700 is joined to the bracket portion 10 and the power portion 20. The first shaft member 710 constitutes one side of the shaft member 700 in the extending direction, that is, the front side in the illustrated embodiment.

[0336] The first shaft member 710 is engaged with the bracket portion 10. Specifically, the first shaft member 710 passes through the motor member engagement hole 312 of the motor member engagement portion 310.

[0337] The first shaft member 710 is coupled to the power unit 20. Specifically, the first shaft member 710 is coupled to the gear shaft 510 that passes through the motor member coupling hole 312.

[0338] The first shaft member 710 is engaged with the second shaft member 720. One side of the first shaft member 710 in the extension direction, i.e., the rear end, is engaged with the second shaft member 720. At this time, the first shaft member 710 can be joined with the second shaft member 720.

[0339] The first shaft member 710 can be any shape that can be supported by the bracket portion 10 and rotate. In the illustrated embodiment, the first shaft member 710 is a cylindrical shape with a circular cross-section and a length in the front-rear direction.

[0340] In the illustrated embodiment, the first shaft member 710 includes a gear shaft engagement portion 711 and a shaft identification surface 712.

[0341] The gear shaft engagement portion 711 is a space for accommodating the gear shaft 510. The gear shaft engagement portion 711 is recessed on the opposite side of the extending direction of the first shaft member 710, i.e., the front end face. The gear shaft engagement portion 711 can be recessed to accommodate at least partially the length of the gear identification surface 520 formed on the gear shaft 510.

[0342] The inner surface of the first shaft member 710 surrounding the gear shaft engagement 711 can be defined as the shaft identification surface 712.

[0343] The shaft identification surface 712 contacts the gear identification surface 520 of the gear shaft 510 housed in the gear shaft joint 711. Due to the contact between the shaft identification surface 712 and the gear identification surface 520, slippage between the gear shaft 510 and the first shaft member 710 can be prevented.

[0344] The shaft identification surface 712 is defined as the inner surface of the first shaft member 710 surrounding the gear shaft engagement portion 711. The shaft identification surface 712 is positioned correspondingly to the gear shaft engagement portion 711. In the illustrated embodiment, the shaft identification surface 712 is arranged adjacent to the other end, i.e., the front end, in the extending direction of the first shaft member 710.

[0345] The shaft identification surface 712 may be formed to be flatter than the outer periphery of the first shaft member 710. In one embodiment, the shaft identification surface 712 may be formed as a plane extending in a horizontal or vertical direction.

[0346] The shaft identification surface 712 can be formed in a plurality of ways. The plurality of shaft identification surfaces 712 can be arranged spaced apart from each other along the inner periphery of the first shaft member 710. In the illustrated embodiment, there are two pairs of shaft identification surfaces 712. One pair of shaft identification surfaces 712 is arranged spaced apart in the vertical direction. The other pair of shaft identification surfaces 712 is arranged spaced apart in the horizontal direction. Each pair of shaft identification surfaces 712 contacts the plurality of shaft identification surfaces 712.

[0347] The shape and configuration of the shaft recognition surface 712 can be changed according to the shape and configuration of the gear recognition surface 520.

[0348] The first shaft member 710 and the second shaft member 720 are combined and rotate together.

[0349] The second shaft member 720 is the other configuration of the shaft member 700, namely the portion of the shaft member 700 that is combined with the circuit breaker (not shown) and the distribution frame 2. The second shaft member 720 constitutes the other side of the extension direction of the shaft member 700, namely the rear side in the illustrated embodiment.

[0350] The second shaft member 720 is coupled to the distribution board 2c. Specifically, the second shaft member 720 is coupled through the lead-in / lead-out device coupling 2d. The second shaft member 720 is supported by the lead-in / lead-out device coupling 2d and is rotatable. One end of the second shaft member 720 in the extending direction, i.e. the rear end in the illustrated embodiment, is coupled to a circuit breaker (not shown) located in the distribution frame space 2b.

[0351] The second shaft member 720 is coupled to the first shaft member 710. Specifically, the other end of the second shaft member 720 in its extending direction, i.e., the front end in the illustrated embodiment, is coupled to the first shaft member 710. As described above, in one embodiment, the coupling may be a butt coupling.

[0352] The second shaft member 720 can be any shape that can be rotatably supported by the lead-in / lead-out device joint 2d. In the illustrated embodiment, the second shaft member 720 is a cylindrical shape with a circular cross-section and a length in the front-rear direction.

[0353] In the illustrated embodiment, the second shaft member 720 includes a key protrusion 721.

[0354] The key protrusion 721 protrudes radially from the outer periphery of the second shaft member 720. The key protrusion 721 can limit the insertion angle of the shaft member 700. That is, the shaft member 700 can only penetrate and engage with the bracket portion 10 and the distribution plate 2c when the angle of the key protrusion 721 through the additional groove and keyway 313 formed in the lead-out device engagement portion 2d is adjusted.

[0355] The key protrusion 721 is disposed adjacent to one end of the second shaft member 720 in the extending direction, i.e., the rear end in the illustrated embodiment. The key protrusion 721 extends along the extending direction of the second shaft member 720, i.e., in the front-rear direction in the illustrated embodiment.

[0356] There may be a plurality of key protrusions 721. The plurality of key protrusions 721 may be spaced apart from each other and arranged in different positions. In the illustrated embodiment, the key protrusions 721 are arranged spaced apart in the vertical direction.

[0357] The number, shape, and arrangement of the key protrusions 721 can be changed according to the number, shape, and arrangement of the additional grooves and keyways 313 of the lead-out device joint 2d.

[0358] Reference Figures 19 to 22 As an example, the process of integrating the lead-out device 1 with the power distribution frame 2 according to an embodiment of the present invention is shown. It can be understood that through the process, the lead-out device 1 is integrated not only with the power distribution frame 2, but also with a circuit breaker (not shown) housed inside the power distribution frame 2.

[0359] Reference Figure 19 The lead-in / lead-out device 1 and the power distribution frame 2 are arranged side by side. At this time, the lead-in / lead-out device cover member 2e provided on the power distribution board 2c rotates to open the lead-in / lead-out device joint 2d. The shaft member 700 of the lead-in / lead-out device 1 is arranged side by side with the lead-in / lead-out device joint 2d. At this time, it can be understood that the shaft member 700 is arranged side by side along the direction in which the lead-in / lead-out device 1 and the power distribution frame 2 are joined or separated, that is, in the front-back direction in the illustrated embodiment.

[0360] Reference Figure 20The shaft member 700 of the lead-in / lead-out device 1 moves forward first and penetrates and engages with the lead-in / lead-out device engagement portion 2d. At this time, it can be understood that the key protrusion 721 provided on the second shaft member 720 is engaged with the lead-in / lead-out device engagement portion 2d through the additional groove formed in the lead-in / lead-out device engagement portion 2d.

[0361] Due to the aforementioned connection, the end of the second shaft member 720 in the extending direction, i.e. the rear end in the illustrated embodiment, can be connected to a circuit breaker (not shown) housed in the power distribution frame space 2b.

[0362] It is understood that the process is based on the handle portion 30, which is composed of shaft member 700, and other components of the lead-in and lead-out device 1, namely the bracket portion 10 and the power portion 20, which are detachably combined.

[0363] Reference Figure 21 The bracket portion 10 moves forward and engages with the handle portion 30, which is connected to the handle portion 30 of the power distribution board 2c. At this time, the first shaft member 710 passes through the keyway 313 of the power unit support portion 300 and is supported by the connecting plate 311 and the connecting boss 314.

[0364] Furthermore, the magnet component 210 of the connecting component 200 contacts and engages with the distribution board 2c. At this time, it can be understood that the engagement force between the magnet component 210 and the distribution board 2c can be adjusted by operating the handle component 220.

[0365] Therefore, the bracket portion 10 can be connected to multiple parts, namely the distribution board 2c and the handle portion 30. As a result, the connection between the bracket portion 10 and the lead-in / lead-out device 1 can be stably maintained.

[0366] Reference Figure 22 The power unit 20 moves forward and engages with the bracket unit 10 and the handle unit 30, respectively. The gear shaft 510 is accommodated in the gear shaft engagement portion 711. At this time, the gear shaft 510 is configured such that the gear identification surface 520 and the shaft identification surface 712 are parallel to each other and are accommodated in contact with the gear shaft engagement portion 711. Therefore, slippage between the gear shaft 510 and the handle unit 30 can be prevented.

[0367] Furthermore, the power unit 20 and the bracket unit 10 are combined such that the guide profile 320 is accommodated in the bracket accommodating space 623 of the power bracket 600. The guide profile 320 accommodated in the bracket accommodating space 623 supports the first bracket plate 621 of the combined bracket 620 from below. In addition, the second bracket plate 622 supports each side of the guide profile 320 in the width direction, namely the left and right sides.

[0368] Meanwhile, the guide rail 630 is slidably coupled to the guide groove 322. As a result, the power unit 20 can move in the direction coupled to the power distribution frame 2, i.e., the front side, and can prevent swaying in the width or height direction.

[0369] On the other hand, if the power unit 20 moves forward to a preset position, the fixing hole 324 is located vertically below the power stop 650. The power stop 650, which applies pressure to the upper side of the profile body 321 and moves there, is inserted into the fixing hole 324, thereby restricting further movement of the power unit 20.

[0370] In the stated state, if the power fixing member 640 is operated and inserted into the connecting groove 323, applying pressure to the surface of the profile body 321 surrounding the lower side of the connecting groove 323, the power unit 20 can be fixed in a preset position.

[0371] Although not illustrated, it is understandable. Figures 19 to 22 The process shown can also be reversed, allowing the lead-out device 1 to be separated from the power distribution frame 2.

[0372] The lead-in / lead-out device 1 of the present invention described above is configured such that the bracket portion 10, the power portion 20, and the handle portion 30 are all separable. Therefore, when the lead-in / lead-out device 1 is combined with the power distribution frame 2, each component can be separated and sequentially combined with the power distribution frame 2 and other components, thereby improving operational convenience.

[0373] Furthermore, the power unit 20 and the bracket unit 10 are supported by a plurality of components and shaft members 700. Therefore, the bonding force between the various components of the lead-out device 1 and the bonding force with the power distribution frame 2 can be increased.

[0374] Furthermore, the bracket portion 10 includes a guide groove 322, and the power unit 20 includes a guide rail 630 slidably coupled to the guide groove 322. Due to this coupling, the power unit 20 can move along the extension direction of the guide profile 320 and is restricted from moving in other directions.

[0375] On the other hand, the power unit 20 includes a power fixing member 640 and a power stop member 650, and the bracket part 10 includes a mating groove 323 and a fixing hole 324. The operator can move the power unit 20 to a preset position simply by moving it until the power stop member 650 engages with the fixing hole 324. Furthermore, the operator can hold the power unit 20 in a preset position simply by inserting the power fixing member 640 into the mating groove 323 and applying pressure to the guide profile 320.

[0376] As a result, the process of connecting and disconnecting the lead-in device 1 from the power distribution frame 2 can be easily performed.

[0377] The embodiments of the present invention have been described, but the spirit of the present invention is not limited to the embodiments set forth in this specification. Those skilled in the art who understand the spirit of the present invention can easily propose other embodiments by adding, changing, deleting, or supplementing the constituent elements within the same spirit scope, but these embodiments are also included within the spirit scope of the present invention.
