Description

[Technical field]

[0001] The present invention relates to a slot member and a power electronic device including the same, and more particularly to a slot member having a structure that can be easily inserted or removed from a housing by being coupled with a capacitor in a modular form, and a power electronic device including the same. [Background technology]

[0002]

[0002] A PLC (Programmable Logic Circuit), a type of power device, is a programmable logic control device that is widely used for automatic control of equipment and process control for performing discontinuous operations, etc. A PLC is equipped with a PCB for processing control signals and a capacitor for supplying power to the PCB.

[0003]

[0003] An example of a capacitor for miniaturizing a PLC and supplying power to various components housed therein is the Electric Double Layer Capacitor (EDLC). The EDLC stores electrical energy by using the electric double layer phenomenon to adsorb and desorb charges. The EDLC is configured to be connected to a PCB or the like and transmit the stored power to the PCB.

[0004]

[0004] Recently, as the specifications of PLCs have become more sophisticated, the capacity of electrical devices accommodated in the PLCs has increased, and as a result, the capacity and number of EDLCs for transmitting power to each component of the PLC have also increased.

[0005]

[0005] In a conventional PLC, a capacitor such as an EDLC is fixedly coupled to a PCB housed inside the PLC, that is, the capacitor is provided on the PCB in an on-board form.

[0006]

[0006] Due to the above-mentioned connection structure, when performing maintenance on the EDLC, it is necessary to disassemble the PLC and separate the PCB and the capacitor connected thereto.

[0007]

[0007] Therefore, the work can only be performed by specialized personnel, and it is difficult to respond quickly when a problem occurs. Furthermore, in order to replace the capacitor, the PCB, which does not require maintenance, must also be replaced, which requires a lot of cost and may reduce customer satisfaction.

[0008]

[0008] In addition, the capacitor and the PCB can only be separated when the power supply to the entire PLC is cut off, which not only reduces the operational reliability of the electric devices that are controlled by the PLC, but also reduces the efficiency of the operation.

[0009] Korean Patent Publication No. 10-2012-0014521 discloses an image processing board and a display device having the same. Specifically, the image processing board has a structure in which a card can be easily connected to a card connection terminal using a guide rail, and the display device has the same.

[0010] However, the prior art only discloses a method for coupling between a card and a card connection terminal that is based on the assumption that the card and the card connection terminal are coupled in an insertion structure, and does not provide a method for providing an element for storing power, such as a capacitor, separately from the PCB.

[0011]

[0011] Korean Patent Publication No. 10-2020-0048376 discloses a sub-module of a modular multi-level converter. Specifically, the sub-module of the modular multi-level converter is capable of removably coupling a capacitor to a housing in a hot swap manner.

[0012] However, the above-mentioned prior art document only presents a concept of a method for coupling a capacitor to a housing, i.e., the coupling between a capacitor and other components disclosed in the above-mentioned prior art document is related to an electrical coupling method based on a circuit diagram, and the above-mentioned prior art document does not present a structural scheme for detachably coupling a capacitor to a housing.

Effect of the Invention

[0042]

[0042] With the above-described configuration, the slot member according to the embodiment of the present invention and the power electronic device including the same can be provided with a modularized capacitor.

[0043]

[0043] The capacitor is provided in a capacitor assembly that is separable from the housing. The capacitor assembly includes a capacitor and a capacitor substrate that is coupled to and energized with the capacitor. The capacitor substrate is coupled to and energized with the capacitor connector.

[0044]

[0044] The capacitor assembly is seated in the slot member. The slot member is configured to be slidably moved and drawn into or drawn out of the housing. The slot member includes a slot body in which the capacitor assembly is seated and a capacitor support portion that supports corners of the seated capacitor assembly at a plurality of positions. The capacitor support portion is formed to partially cover an upper side of the seated capacitor assembly to prevent any deviation of the capacitor assembly.

[0045]

[0045] The capacitor assembly and the slot member can be pulled or pulled together into the housing. A PCB assembly is provided in a space formed inside the housing. By pulling the capacitor assembly and the slot member into the space formed inside the housing, the capacitor connector can be inserted and coupled to the connector of the PCB assembly.

[0046]

[0046] Therefore, the capacitor can be modularized by the capacitor assembly and removably coupled to the housing.

[0047]

[0047] Also, due to the above configuration, the slot member according to the embodiment of the present invention and the power electronic device including the same do not require a process of separating all components for maintenance of the capacitor.

[0048]

[0048] As described above, the capacitor is provided in a capacitor assembly. The capacitor assembly and the slot member supporting the capacitor are coupled to the housing in a removable manner. When repair of the capacitor is required, the capacitor assembly and the slot member coupled thereto can be removed to perform maintenance on the capacitor.

[0049]

[0049] Therefore, the capacitor can be maintained without disassembling the entire power electronic device, and other components that are connected to the capacitor, such as a PCB board, can be used without a replacement process, improving user convenience and satisfaction.

[0050]

[0050] Furthermore, with the above-described configuration, the slot member according to the embodiment of the present invention and the power electronic device including the same can easily couple and separate the capacitors.

[0051]

[0051] A guide member is coupled to the PCB assembly. The guide member extends along a direction in which the capacitor assembly and the slot member are retracted into or pulled out from the housing. A plurality of guide members are provided and are spaced apart from each other along the width direction of the capacitor assembly or the slot member.

[0052]

[0052] A guide hollow is formed inside the guide member, penetrating along the extension direction of the guide member. The outside of the guide hollow is surrounded by a plurality of extensions. The inside of the guide hollow, i.e., each side where the plurality of guide members face each other, is formed open and communicates with the insertion space formed between the plurality of guide members.

[0053]

[0053] Each corner of the width direction of the capacitor assembly and the slot member is guided by the guide member while being inserted into the guide hollow, and can be slid and pulled into or pulled out of the housing. At this time, the movement direction of the capacitor assembly and the slot member is limited to the direction of being pulled into or pulled out of the housing by the multiple extensions surrounding the guide hollow.

[0054]

[0054] At this time, the guide members are coupled to the PCB assembly with a predetermined interval therebetween, and the distance at which the guide members are spaced apart is equal to or greater than the width of the capacitor assembly and the slot member.

[0055]

[0055] Therefore, even when an operator with low skill performs the operation, the capacitor assembly and the slot member can be easily drawn into or drawn out from the housing.

[0056]

[0056] Furthermore, with the above-described configuration, the slot member according to the embodiment of the present invention and the power electronic device including the same can easily establish an electrically conductive state between the capacitor and other components.

[0057]

[0057] The PCB assembly is provided with a connector. The connector is arranged to overlap the insertion space along the direction in which the capacitor assembly and the slot member are retracted or pulled out. The connector is also arranged to be located on the same line as the capacitor connector provided in the capacitor assembly.

[0058] In one embodiment, the connector and the capacitor connector can be coupled and energized in a form in which the capacitor connector is inserted into the connector. By drawing in the capacitor assembly and the slot member, the capacitor connector is inserted and coupled into the connector, and the PCB assembly and the capacitor assembly can be energized.

[0059]

[0059] At this time, the guide members may be arranged to surround the widthwise corners of the capacitor assembly and the slot member, thereby preventing the capacitor assembly and the slot member from moving in different directions.

[0060]

[0060] Therefore, simply by drawing the capacitor assembly and the slot member into the receiving space of the housing, the capacitor assembly and the PCB assembly can be energized without any additional wiring work.

[0061]

[0061] In addition, due to the above-mentioned configuration, the slot member according to the embodiment of the present invention and the power electronic device including the same do not require a separate tool or fastening member for coupling and decoupling the capacitor.

[0062]

[0062] The slot member and the capacitor assembly coupled thereto are coupled to the housing by a gripping portion provided on the slot member. The gripping portion includes an insertion protrusion formed to protrude outward in the width direction. The insertion protrusion is coupled to and moves together with a pressure protrusion disposed on the outer side of the gripping portion at a distance from the end of the gripping portion in the width direction.

[0063]

[0063] The pressure projection is made of a material having a certain elasticity, and can be moved toward the end of the gripping part by an external force applied in a widthwise inward direction. When the application of the external force is released, the pressure projection can be restored to the widthwise outward direction of the gripping part by the stored restoring force.

[0064]

[0064] The housing has an insertion opening through which the slot member and the capacitor assembly coupled thereto pass. The insertion opening is surrounded by a support frame. The support frame is formed to have a predetermined thickness. The insertion protrusion and the pressure protrusion are formed to be equal to or greater than the thickness of the support frame.

[0065]

[0065] The insertion protrusion that has entered the insertion opening is pressed by the support frame and moved inward in the width direction of the gripping portion. As the slot member and the capacitor assembly coupled thereto are pulled in, the insertion protrusion is positioned so as to exceed the inner end of the support frame in the thickness direction.

[0066]

[0066] In the above state, the external force applied to the insertion protrusion disappears, and the insertion protrusion moves together with the pressure protrusion to the position before the external force was applied, that is, to the outside in the width direction of the gripping portion. As a result, the insertion protrusion is positioned inside the inner end of the support frame, and the gripping portion and the housing are connected. In other words, the gripping portion and the housing can be snap-connected.

[0067]

[0067] After the housing and the slot member are connected, when an external force toward the inside of the width direction of the gripping part is applied to the pressure protrusion, the insertion protrusion is also moved toward the inside. This releases the snap connection between the insertion protrusion and the support frame. The operator can pull out the slot member while pressing the pressure protrusion.

[0068]

[0068] At this time, a locking protrusion is provided at an end in the extension direction of the slot member to support the end in the extension direction of the capacitor assembly, that is, the capacitor assembly can be pulled out of the housing together with the slot member by the locking protrusion.

[0069]

[0069] Therefore, the capacitor assembly and its associated slot member can be easily coupled to the housing and PCB assembly without the need for additional tools or fasteners.

[0070]

[0070] Furthermore, with the above-described configuration, the slot member according to the embodiment of the present invention and the power electronic device including the same can stably maintain the coupled state between the capacitor and other components.

[0071]

[0071] As described above, the insertion protrusion is snap-connected to the support frame, and the connection state between the insertion protrusion and the support frame can be maintained unless another external force is applied to the pressure protrusion.

[0072]

[0072] The pressure projection is accommodated in a gripping space recessed into the housing. The pressure projection is arranged so as not to protrude from the outer surface of the housing, thereby preventing the pressure projection from being arbitrarily applied by the external environment. In other words, the pressure projection can transmit only the external force intentionally applied by the operator.

[0073]

[0073] Therefore, the coupling state between the slot member and the capacitor assembly coupled thereto and the housing can be stably maintained, and thus the electrical connection state between the capacitor assembly and the PCB assembly can also be stably maintained.

[0074]

[0074] The effects of the present invention are not limited to the effects described above, but should be understood to include all effects that can be inferred from the configuration of the invention described in the detailed description of the present invention or the claims.

[0116] In the embodiment shown, the power electronics 10 includes a housing 100 , a PCB assembly 200 , a guide member 300 , a capacitor assembly 400 , and a slot member 500 .

[0094]

[0117] The housing 100 forms the outer shape of the power electronics 10. A space may be formed inside the housing 100 to accommodate other components of the power electronics 10. In the illustrated embodiment, the housing 100 accommodates a PCB assembly 200, a guide member 300, a capacitor assembly 400, and a slot member 500.

[0095]

[0118] The housing 100 may be formed of a material that is highly rigid and has electrical and thermal insulation properties in order to prevent damage due to external impact, heat, etc., and to prevent any electrical connection between other components accommodated inside the housing 100 and the outside.

[0096]

[0119] The housing 100 may be made of a lightweight material. In the embodiment, movement of the power electronics device 10 may be easily achieved.

[0097]

[0120] In one embodiment, the housing 100 may be formed from a synthetic resin material such as polycarbonate.

[0098]

[0121] The inside of the housing 100 communicates with the outside. The PCB assembly 200, the capacitor assembly 400, and the like contained in the housing 100 can be cooled by a fluid, such as air, that is introduced into the housing 100.

[0099]

[0122] The inside of the housing 100 is electrically connected to the outside. The PCB assembly 200, the capacitor assembly 400, and the like contained in the housing 100 can be electrically connected to an external electric device.

[0100]

[0123] The housing 100 may be provided in any form capable of housing the components of the power electronic device 10 therein and preventing any exposure of the housed components. In the illustrated embodiment, the housing 100 is a rectangular prism having a longer extension length in the front-rear direction than in the left-right direction and a greater height in the up-down direction.

[0101]

[0124] A plurality of ribs may be formed on the outer surface of the housing 100, in the illustrated embodiment, on the front side surface. The plurality of ribs may be configured to enhance the rigidity of the housing 100. In addition, since the capacitor assembly 400 described below is retracted or pulled out from the front side surface, the plurality of ribs may allow an operator to recognize the retracting direction of the capacitor assembly 400.

[0102]

[0125] In the embodiment shown, the housing 100 includes an upper housing 101, a lower housing 102, an operation button 103, and an accommodating space 104 (see FIG. 24).

[0103]

[0126] The housing 100 may be divided into multiple sections. In the embodiment shown, the housing 100 includes an upper housing 101 located on an upper side and a lower housing 102 located on a lower side and coupled to the upper housing 101.

[0104]

[0127] The upper housing 101 and the lower housing 102 may be detachably coupled to each other. In one embodiment, the upper housing 101 and the lower housing 102 may be easily coupled to each other by a hook fit. In the embodiment, the coupled upper housing 101 and lower housing 102 are not arbitrarily separated unless an external force of a certain magnitude or more is applied in a specific direction.

[0105]

[0128] A space is formed inside each of the upper housing 101 and the lower housing 102. The spaces accommodate other components of the power electronic device 10. The space formed inside the upper housing 101 and the space formed inside the lower housing 102 communicate with each other and are defined as an accommodation space 104.

[0106]

[0129] One side of the upper housing 101, in the illustrated embodiment, the upper side, is provided with a plurality of operation buttons 103. The operation buttons 103 can be pressed by an operator to apply a control signal for controlling the operation of the power electronic device 10. Alternatively, the operation buttons 103 can be provided in the form of a touch screen, a dial, or the like.

[0107]

[0130] The accommodating space 104 is a space formed inside the housing 100. The accommodating space 104 accommodates other components of the power electronic device 10, namely, the PCB assembly 200, the guide member 300, the capacitor assembly 400, and the slot member 500. The accommodating space 104 is surrounded by each side of the housing 100 and is not arbitrarily exposed to the outside.

[0108]

[0131] The accommodation space 104 may be in communication with the outside and may be electrically connected to the outside. This allows a fluid to flow in for cooling the PCB assembly 200 and the capacitor assembly 400 accommodated in the accommodation space 104. In addition, the PCB assembly 200 and the capacitor assembly 400 accommodated in the accommodation space 104 may be electrically connected to an external electric device.

[0109]

[0132] 4 and 5, the housing 100, specifically the upper housing 101, is provided with an insertion opening 110, a support frame 120, and a gripping space .

[0110]

[0133] The insertion opening 110 communicates the receiving space 104 with the outside. The insertion opening 110 is formed penetrating in the thickness direction of one of the surfaces of the housing 100. In the illustrated embodiment, the insertion opening 110 is formed penetrating in the front side surface of the upper housing 101.

[0111]

[0134] The capacitor assembly 400 and the slot member 500 coupled thereto may be inserted through the insertion opening 110. The capacitor assembly 400 and the slot member 500 coupled thereto may be inserted into the accommodating space 104 or pulled out from the accommodating space 104 through the insertion opening 110.

[0112]

[0135] The insertion opening 110 may be of any shape that allows the capacitor assembly 400 and slot member 500 to pass therethrough. In the embodiment shown, the insertion opening 110 is formed to have a rectangular cross-section with a longer left-to-right length than it has a longer top-to-bottom length.

[0113]

[0136] The inner periphery of the housing 100 surrounding the insertion opening 110 may be defined as a support frame 120 .

[0114]

[0137] The support frame 120 surrounds the insertion opening 110 from the outside. In other words, the support frame 120 may be said to be the boundary of the insertion opening 110.

[0115]

[0138] When the slotted member 500 is retracted into the housing 100, the support frame 120 can be disposed to surround the gripping portion 510. That is, the support frame 120 supports the gripping portion 510 of the slotted member 500 from the outside.

[0116]

[0139] Also, the inner side of the support frame 120, i.e., the portion facing the receiving space 104, can be snap-fitted with the insertion protrusion 513 of the slot member 500. In the illustrated embodiment, the rear side portion of the support frame 120 can be coupled with the insertion protrusion 513.

[0117]

[0140] The support frame 120 may be divided into multiple sections, i.e., because the insertion opening 110 is formed to have a polygonal cross section as described above, the support frame 120 may be divided into multiple corners surrounding the insertion opening 110.

[0118]

[0141] In the embodiment shown, the support frame 120 includes a first portion 121 , a second portion 122 , a third portion 123 , a fourth portion 124 , and an identification protrusion 125 .

[0119]

[0142] The first portion 121 forms part of the support frame 120. The first portion 121 surrounds the insertion opening 110 from one side, in the embodiment shown, from the upper side. Thus, it may be said that the first portion 121 forms the upper side of the support frame 120.

[0120]

[0143] One corner of the first portion 121 facing the receiving space 104, in the illustrated embodiment, a rear side corner, can be snap-coupled with an insertion protrusion 513 described below. A first gripping space portion 131 is formed on one side of the first portion 121 opposite to the insertion opening 110, in the illustrated embodiment, the upper side.

[0121]

[0144] The first portion 121 extends in the width direction of the insertion opening 110, in the left-right direction in the illustrated embodiment. The first portion 121 is continuous with the third portion 123 and the fourth portion 124. The first portion 121 is disposed to face the second portion 122 across the insertion opening 110.

[0122]

[0145] The second portion 122 forms another part of the support frame 120. The second portion 122 surrounds the insertion opening 110 from the other side, in the embodiment shown, from the underside. Thus, it may be said that the second portion 122 forms the underside of the support frame 120.

[0123]

[0146] One corner of the second portion 122 facing the receiving space 104, in the illustrated embodiment, a rear side corner, can be snap-coupled with an insertion protrusion 513 described below. A second gripping space portion 132 is formed on one side of the second portion 122 opposite the insertion opening 110, in the illustrated embodiment, the lower side.

[0124]

[0147] The second portion 122 extends in the width direction of the insertion opening 110, in the left-right direction in the illustrated embodiment. The second portion 122 is continuous with the third portion 123 and the fourth portion 124. The second portion 122 is disposed opposite the first portion 121 across the insertion opening 110.

[0125]

[0148] The third portion 123 forms another part of the support frame 120. The third portion 123 surrounds the insertion opening 110 from the other side, in the embodiment shown, the right side. Thus, it may be said that the third portion 123 forms the right side of the support frame 120.

[0126]

[0149] The third portion 123 extends in the height direction of the insertion opening 110, in the vertical direction in the illustrated embodiment. The third portion 123 is continuous with the first portion 121 and the second portion 122. The third portion 123 is disposed opposite the fourth portion 124 and the identification protrusion 125 across the insertion opening 110.

[0127]

[0150] Meanwhile, the third portion 123 may be formed to have a different shape from the fourth portion 124 and the identification protrusion 125. That is, in the illustrated embodiment, the third portion is formed to extend linearly along the vertical direction. Meanwhile, the fourth portion 124 is formed to extend linearly along the vertical direction, but the identification protrusion 125 is formed to protrude toward the insertion opening 110.

[0128]

[0151] Thus, one side on which the third portion 123 is located (i.e., the right side in the embodiment shown) and the other side on which the fourth portion 124 and the identification protrusion 125 are located (i.e., the left side in the embodiment shown) can be easily identified on the outside of the housing 100.

[0129]

[0152] This allows easy recognition of the insertion direction of the capacitor assembly 400 and the slot member 500, which will be described later in detail.

[0130]

[0153] The fourth portion 124 forms another part of the support frame 120. The fourth portion 124 partially surrounds the insertion opening 110 from the other side, in the embodiment shown, the left side. Thus, it may be said that the fourth portion 124 forms a part of the left side of the support frame 120.

[0131]

[0154] The fourth portion 124 may include a plurality of portions. In the illustrated embodiment, the fourth portion 124 is formed on the upper side and the lower side of the identification protrusion 125, respectively. In other words, the fourth portion 124 is provided in a pair arranged to face each other with the identification protrusion 125 in between.

[0132]

[0155] The fourth portions 124 extend in the height direction of the insertion opening 110, in the vertical direction in the illustrated embodiment. One portion of the pair of fourth portions 124 located on the upper side is continuous with the first portion 121 and the identification protrusion 125. The other portion of the pair of fourth portions 124 located on the lower side is continuous with the second portion 122 and the identification protrusion 125.

[0133]

[0156] The fourth portion 124 is disposed opposite the third portion 123 with the insertion opening 110 interposed therebetween.

[0134]

[0157] The identification protrusion 125 forms part of the remainder of the support frame 120. The identification protrusion 125 partially surrounds the insertion opening 110 from the other side, in the embodiment shown, the left side. Thus, it may be said that the identification protrusion 125 forms part of the remainder of the left side of the support frame 120.

[0135]

[0158] The identification protrusion 125 is formed to protrude a predetermined length toward the insertion opening 110. The identification protrusion 125 causes the support frame 120 and the left and right portions of the insertion opening 110 surrounded thereby to have different shapes. As a result, the insertion directions of the capacitor assembly 400 and the slot member 500 can be easily identified, as described above.

[0136]

[0159] The identification protrusion 125 is disposed between the plurality of fourth portions 124. In the illustrated embodiment, the identification protrusion 125 is disposed between a pair of the fourth portions 124 along the up-down direction.

[0137]

[0160] The identification protrusion 125 extends in the height direction of the insertion opening 110, in the vertical direction in the illustrated embodiment. The identification protrusion 125 is continuous with the pair of fourth portions 124, respectively.

[0138]

[0161] Identification protrusion 125 protrudes in the width direction of insertion opening 110, or in the left-right direction in the illustrated embodiment. It is desirable that the protruding length of identification protrusion 125 is formed to be long enough so as not to impede the insertion and extraction of capacitor assembly 400 but to be distinguishable by an operator with the naked eye or touch.

[0139]

[0162] The identification protrusion 125 may be formed on any portion of the support frame 120 that circumferentially surrounds the insertion opening 110. In the illustrated embodiment, the identification protrusion 125 is disposed opposite the third portion 123 across the insertion opening 110.

[0140]

[0163] Alternatively, the identification protrusion 125 may be formed on any one or more of the first portion 121, the second portion 122, the third portion 123, and the fourth portion 124. In any case, it is sufficient if an operator can easily recognize the direction in which the capacitor assembly 400 and the slot member 500 coupled thereto are inserted into the housing 100. In the above case, the identification protrusion 125 may be continuous with any one or more of the above portions.

[0141]

[0164] The gripping space 130 receives the pressure protrusion 512 of the slot member 500. An operator can insert a finger into the gripping space 130 and press the pressure protrusion 512. By applying pressure, the slot member 500 and the capacitor assembly 400 coupled thereto can be pulled out of the housing 100.

[0142]

[0165] In addition, the gripping space 130 accommodates the pressure protrusion 512 to prevent the pressure protrusion 512 from protruding outside the housing 100. In other words, the gripping space 130 compensates for the thickness of the pressure protrusion 512 and adjusts the outer surface of the slot member 500 and the outer surface of the housing 100 to be positioned on the same plane.

[0143]

[0166] The gripping space 130 is recessed into the outer surface of the housing 100. In the illustrated embodiment, the gripping space 130 is recessed into the front side surface of the upper housing 101. The recessed length of the gripping space 130 is preferably equal to or greater than the thickness of the pressure protrusion 512.

[0144]

[0167] The gripping space 130 is located adjacent to the insertion opening 110. The gripping space 130 communicates with the insertion opening 110. This allows a portion of the slot member 500 to be accommodated in the insertion opening 110, and the pressure protrusion 512 to be accommodated in the gripping space 130.

[0145]

[0168] The gripping space 130 is located adjacent to a plurality of portions of the support frame 120. In the illustrated embodiment, the gripping space 130 is located adjacent to the first portion 121 and the second portion 122, respectively.

[0146]

[0169] The gripping space 130 may be of any shape that communicates with the insertion opening 110 and can accommodate the pressure projection 512. In the embodiment shown, the gripping space 130 is formed to have a rectangular cross section whose extension length in its width direction, i.e., in the embodiment shown, the left-right direction, is longer than its extension length in its height direction, i.e., in the embodiment shown, the up-down direction.

[0147]

[0170] At this time, it is preferable that the length in the width direction of the gripping space portion 130 is formed to be equal to or greater than the height of the pressure protrusion 512. In addition, the length in the height direction of the gripping space portion 130 is formed to be equal to or greater than the width of the pressure protrusion 512, but is preferably formed to be sufficiently long so that an operator's finger or the like can be inserted therein.

[0148]

[0171] A plurality of gripping spaces 130 may be formed. The plurality of gripping spaces 130 are spaced apart from each other and can accommodate the pressure projections 512 at different positions. In the illustrated embodiment, a pair of gripping spaces 130 are provided, including a first gripping space 131 located on the upper side and a second gripping space 132 located on the lower side.

[0149]

[0172] The first gripping space 131 is located adjacent to one side in the extension direction of the insertion opening 110, in the illustrated embodiment, the upper side. The first gripping space 131 communicates with the one side end of the insertion opening 110, i.e., the upper end.

[0150]

[0173] The second gripping space 132 is located adjacent to the other side in the extension direction of the insertion opening 110, that is, the lower side in the illustrated embodiment. The second gripping space 132 communicates with the other end of the insertion opening 110, i.e., the lower end.

[0151]

[0174] The first gripping space portion 131 and the second gripping space portion 132 are disposed opposite the insertion opening 110 and spaced apart from each other along the extension direction of the insertion opening 110, which in the illustrated embodiment is the up-down direction.

[0152]

[0175]

[0176] Referring again to FIG. 3, the power electronics 10 according to the illustrated embodiment includes a PCB assembly 200 .

[0153]

[0177] The PCB assembly 200 is electrically connected to an external electric device to substantially perform the function of the power electronic device 10. The PCB assembly 200 is electrically connected to the capacitor assembly 400 so that the power required for operation can be transmitted.

[0154]

[0178] The PCB assembly 200 is mounted inside the housing 100. In the embodiment shown, the PCB assembly 200 is accommodated in an accommodating space 104 formed by communication between the internal spaces of the upper housing 101 and the lower housing 102. The PCB assembly 200 is not arbitrarily exposed to the outside.

[0155]

[0179] A guide member 300 is coupled to the PCB assembly 200. The capacitor assembly 400 and the slot member 500 coupled thereto are guided by the guide member 300 and can be coupled to or detached from the PCB assembly 200. The coupling or detachment can be achieved by the capacitor assembly 400 and the slot member 500 coupled thereto being pulled into or pulled out of the housing 100.

[0156]

[0180] The PCB assembly 200 is electrically connected to the capacitor assembly 400. The PCB assembly 200 and the capacitor assembly 400 may be detachably coupled. Power required for the operation of the PCB assembly 200 may be transferred from a capacitor 410 provided in the capacitor assembly 400.

[0157]

[0181] In particular, in the PCB assembly 200 according to the embodiment of the present invention, the capacitor 410 for supplying power is not provided integrally, i.e., on-board, in the PCB assembly 200. In other words, the PCB assembly 200 and the capacitor 410 may be detachably coupled to each other.

[0158]

[0182] Thus, when maintenance of the capacitor 410 or the capacitor assembly 400 including the capacitor 410 is required, only the capacitor assembly 400 may be removed to perform the necessary work.

[0159]

[0183] 6-9, in the embodiment shown, the PCB assembly 200 includes a PCB substrate 210 and a connector 220. As shown in FIG.

[0160]

[0184] The PCB board 210 is in electrical communication with external electronics to perform the functions of the power electronics 10. The PCB board 210 can include various electrical elements that are in electrical communication with each other and operated according to control signals.

[0161]

[0185] The PCB substrate 210 forms the main body of the PCB assembly 200. In the illustrated embodiment, the PCB substrate 210 is provided in a plate shape having a horizontal cross section and a thickness in the vertical direction. In one embodiment, the PCB substrate 210 may be provided in a rectangular plate shape. In this case, it is preferable that the size of the PCB substrate 210 is smaller than the receiving space 104 formed inside the housing 100.

[0162]

[0186] 6, the right side of the rear portion communicates with the outside through an insertion opening 110. A connector 220 is provided on the side of the PCB board 210 to which the capacitor assembly 400 can be detachably coupled.

[0163]

[0187] The operating principle of the PCB board 210 is well known in the art and will not be described in detail.

[0164]

[0188] In the embodiment shown, the PCB substrate 210 includes a PCB through hole 211 .

[0165]

[0189] The PCB through hole 211 is a portion where the guide member 300 is coupled to the PCB board 210. The PCB through hole 211 is formed penetrating the PCB board 210 in the thickness direction, or in the vertical direction in the illustrated embodiment.

[0166]

[0190] A plurality of PCB through holes 211 may be formed. The plurality of PCB through holes 211 may be formed at various positions spaced apart from each other. In the embodiment shown in Figures 7 and 9, three PCB through holes 211 are formed on the left side and three on the right side, for a total of six PCB through holes 211.

[0167]

[0191] At this time, the three PCB through holes 211 formed on the left side are arranged next to each other at a predetermined distance apart in the front-rear direction, and similarly, the three PCB through holes 211 formed on the right side are arranged next to each other at a predetermined distance apart in the front-rear direction.

[0168]

[0192] The multiple PCB through holes 211 formed on the left side and the multiple PCB through holes 211 formed on the right side are arranged to face each other at a distance in the width direction of the PCB board 210, which in the illustrated embodiment is the left-right direction. A space formed between the multiple PCB through holes 211 formed on the left side and the multiple PCB through holes 211 formed on the right side can be defined as an insertion space S.

[0169]

[0193] That is, the plurality of PCB through holes 211 formed on the left side and the plurality of PCB through holes 211 formed on the right side are disposed so as to face each other with the insertion space S therebetween.

[0170]

[0194] The number and arrangement of the PCB through holes 211 may be changed according to the number and arrangement of the coupling protrusions 320 provided on the guide member 300 .

[0171]

[0195] However, it is preferable that at least two PCB through holes 211 are formed on each of the left and right sides. This is because if a single PCB through hole 211 is formed, there is a risk that the guide member 300 coupled thereto may be arbitrarily rotated.

[0172]

[0196] The PCB through hole 211 may have any shape that can be penetrated and coupled with the coupling protrusion 320 of the guide member 300. In the illustrated embodiment, the PCB through hole 211 has a circular horizontal cross section and is formed as a cylindrical space extending in the vertical direction.

[0173]

[0197] The connector 220 is a part to which the capacitor assembly 400 is coupled. The PCB assembly 200 is electrically connected to the capacitor assembly 400 via the connector 220, so that power can be transmitted between the PCB assembly 200 and the capacitor assembly 400.

[0174]

[0198] The connector 220 is coupled to the PCB board 210. The connector 220 is electrically connected to the PCB board 210 so that the power transferred from the capacitor assembly 400 can be transferred to the PCB board 210.

[0175]

[0199] In the embodiment shown, the connector 220 is offset to the rear right side of the PCB substrate 210. The location of the connector 220 may be varied depending on the shape or location of the insertion opening 110 and the capacitor assembly 400 being pulled into and out of the insertion opening 110.

[0176]

[0200] The connector 220 is coupled to a capacitor connector 430 of the capacitor assembly 400. The connector 220 is electrically connected to the capacitor connector 430 so that the power stored in the capacitor 410 can be transferred.

[0177]

[0201] In one embodiment, a space may be formed inside the connector 220, and the capacitor connector 430 may be coupled to the capacitor connector 430 in a retracted manner. In the embodiment, no separate member or operation is required for fastening the connector 220 and the capacitor connector 430, which may improve the convenience and efficiency of the operation.

[0178]

[0202] The PCB through holes 211 are located on the front side of the connector 220. As described above, the PCB through holes 211 are arranged to be spaced apart from each other in the width direction of the PCB board 210 and to face each other with the insertion space S therebetween.

[0179]

[0203] At this time, the connector 220 may be positioned so as to overlap the insertion space S in a direction in which the multiple PCB through holes 211 arranged side by side are spaced apart from each other, that is, in the front-rear direction in the illustrated embodiment.

[0180]

[0204] Therefore, the capacitor connector 430 of the capacitor assembly 400 inserted into the insertion space S can be moved in its extension direction, i.e., in the forward and backward directions in the illustrated embodiment, to be coupled to or detached from the connector 220. The above process will be described in detail later.

[0181]

[0205]

[0206] Referring again to FIG. 3, the power electronics 10 according to the illustrated embodiment includes a guide member 300 .

[0182]

[0207] The guide member 300 guides the movement of the capacitor assembly 400 and the slot member 500 coupled thereto, which are drawn into or drawn out of the housing 100. The capacitor assembly 400 and the slot member 500 coupled thereto can be guided by the guide member 300 in a direction in which they are drawn into or drawn out of the housing 100.

[0183]

[0208] That is, the guide member 300 guides the sliding movement of the capacitor assembly 400 and the slot member 500 coupled thereto.

[0184]

[0209] The guide member 300 can guide at least a portion of the capacitor assembly 400 and the slot member 500 coupled thereto. In one embodiment, the guide member 300 can guide the left and right corner portions of the capacitor assembly 400 and the slot member 500 coupled thereto. It will be understood that in the embodiment, the capacitor connector 430 is located on the front side of the capacitor assembly 400 and is coupled to the connector 220.

[0185]

[0210] The guide member 300 is coupled to the PCB assembly 200. Specifically, the guide member 300 may be coupled to the PCB assembly 200 by the coupling protrusion 320 penetrating the PCB through hole 211 formed through the PCB substrate 210. In one embodiment, the guide member 300 and the PCB assembly 200 may be snap-fitted.

[0186]

[0211] This eliminates the need for a separate member, such as a screw member, for coupling the guide member 300 and the PCB assembly 200. Furthermore, the man hours required to fasten the screw member or the like can be reduced.

[0187]

[0212] In the embodiment shown, the guide member 300 is positioned on the top surface of the PCB board 210, offset to the front right.

[0188]

[0213] As described above, a plurality of PCB through holes 211 may be formed. This allows the guide member 300 to be coupled to the PCB board 210 at a plurality of positions. In the above embodiment, any rotation of the guide member 300 coupled to the PCB board 210 may be prevented.

[0189]

[0214] At this time, the guide member 300 can be coupled to the PCB board 210 with a predetermined gap formed between the guide member 300 and the PCB board 210. In other words, the guide member 300 can be coupled to the PCB board 210 with some play in the insertion direction, which in the illustrated embodiment is the up-down direction. The coupling can be achieved by forming the extension length of the protrusion extension portion 321 of the coupling protrusion 320 longer than the extension length of the PCB through hole 211.

[0190]

[0215] Therefore, when the power electronic device 10 is swung, the amount of impact transmitted between the guide member 300 and the PCB board 210 can be reduced. As a result, damage to the guide member 300 or the PCB board 210 can be prevented compared to when the guide member 300 is tightly coupled to the PCB board 210.

[0191]

[0216] There may be a plurality of guide members 300. The plurality of guide members 300 may be coupled to the PCB board 210 at different positions. In the embodiment shown in Figures 6 to 9, a pair of guide members 300 are provided, including a first guide member 300a and a second guide member 300b.

[0192]

[0217] In an embodiment in which a plurality of guide members 300 are provided, any one or more of the plurality of guide members 300 may form a predetermined gap between themselves and the PCB board 210 and may be coupled to the PCB board 210. Even in the above case, it will be understood that a shock generated in the power electronic device 10 or applied from the outside may be buffered by at least one of the plurality of guide members 300.

[0193]

[0218] The first guide member 300a is coupled to a plurality of PCB through holes 211 formed on the left side. The second guide member 300b is coupled to a plurality of PCB through holes 211 formed on the right side. The first guide member 300a and the second guide member 300b are disposed to face each other with the insertion space S therebetween.

[0194]

[0219] At this time, it is preferable that the distance between the first guide member 300a and the second guide member 300b is greater than the width of the capacitor assembly 400 and the slot member 500 coupled thereto.

[0195]

[0220] Therefore, even if the capacitor assembly 400 and the slot member 500 coupled thereto enter the insertion space S without being in close contact with the first guide member 300a or the second guide member 300b, they can be stably supported.

[0196]

[0221] The first guide member 300a and the second guide member 300b have the same structure, although there are some differences in the position and arrangement method for coupling to the PCB board 210. Therefore, in the following description, matters common to the first guide member 300a and the second guide member 300b will be referred to as the guide member 300.

[0197]

[0222] In the embodiment shown in FIGS. 10-11, the guide member 300 includes a guide body 310 and a coupling protrusion 320. As shown in FIG.

[0198]

[0223] The guide body 310 forms a body of the guide member 300. The guide body 310 is formed to extend in the same direction as the capacitor assembly 400 and the slot member 500 coupled thereto. In the illustrated embodiment, the guide body 310 is formed to extend in the front-rear direction. The guide body 310 can support the capacitor assembly 400 and the slot member 500 coupled thereto and guide their movement.

[0199]

[0224] The guide body 310 is coupled to the PCB board 210. As described above, the surfaces of the guide body 310 and the PCB board 210 facing each other may be spaced apart from each other. This may reduce impact or vibration that occurs between the guide body 310, the capacitor assembly 400 and the slot member 500 supported thereby, and the PCB board 210.

[0200]

[0225] The guide body 310 can support one corner of the capacitor assembly 400 and the slot member 500 coupled thereto. In the illustrated embodiment, the first guide member 300a on the left side supports the left corner of the capacitor assembly 400 and the slot member 500 coupled thereto. The second guide member 300b on the right side supports the right corner of the capacitor assembly 400 and the slot member 500 coupled thereto.

[0201]

[0226] In the embodiment shown in FIGS. 8 to 11, the guide body 310 includes a first extension portion 311, a second extension portion 312, a third extension portion 313, a guide hollow 314, and a guide inclined portion 315.

[0202]

[0227] The first extension 311 forms a part of the guide body 310. In the illustrated embodiment, the first extension 311 forms the horizontal outer side of the guide body 310. The first extension 311 is formed to extend in the height direction of the guide body 310, which in the illustrated embodiment is the up-down direction.

[0203]

[0228] The first extension 311 supports one horizontal corner of the capacitor assembly 400 and the slot member 500 coupled thereto. In the illustrated embodiment, the first extension 311 of the first guide member 300a supports a left corner of the capacitor assembly 400 and the slot member 500 coupled thereto. Also, the first extension 311 of the second guide member 300b supports a right corner of the capacitor assembly 400 and the slot member 500 coupled thereto.

[0204]

[0229] Therefore, it can be said that the first extension portion 311 prevents the capacitor assembly 400 that has entered the insertion space S and the slot member 500 coupled thereto from coming off in the horizontal direction.

[0205]

[0230] At this time, it is preferable that the shortest distance between the first extension portions 311 formed on the first guide member 300a and the second guide member 300b is longer than the width direction lengths of the capacitor assembly 400 and the slot member 500 coupled thereto. In the above embodiment, the capacitor assembly 400 inserted into the insertion space S and the slot member 500 coupled thereto may be arranged to have a predetermined play in the horizontal direction.

[0206]

[0231] The first extension portion 311 is formed to extend in the extension direction of the guide body 310, which is the front-rear direction in the illustrated embodiment. A guide inclined portion 315 is formed at each end of the first extension portion 311 in the extension direction, which is the front-rear direction in the illustrated embodiment.

[0207]

[0232] The first extension 311 partially surrounds the guide hollow 314 in the horizontal direction. In the embodiment shown, the first extension 311 of the first guide member 300a surrounds the left side of the guide hollow 314, and the first extension 311 of the second guide member 300b surrounds the right side of the guide hollow 314.

[0208]

[0233] Therefore, it can be said that the first extension portion 311 surrounds the horizontal outside of the guide hollow 314.

[0209]

[0234] The first extension portion 311 is continuous with the second extension portion 312 and the third extension portion 313 .

[0210]

[0235] The second extension 312 forms another part of the guide body 310. In the illustrated embodiment, the second extension 312 forms one vertical side, i.e., the upper side, of the guide body 310. The second extension 312 is formed to extend in the width direction of the guide body 310, which in the illustrated embodiment is the left-right direction.

[0211]

[0236] The second extension 312 supports one vertical corner of the capacitor assembly 400 and the associated slot member 500. In the embodiment shown, the second extension 312 supports an upper corner of the capacitor assembly 400 and the associated slot member 500.

[0212]

[0237] Therefore, it can be said that the second extension portion 312 prevents the capacitor assembly 400 that has entered the insertion space S and the slot member 500 coupled thereto from being separated in the vertical direction.

[0213]

[0238] The second extension portion 312 is formed to extend in the extension direction of the guide body 310, which is the front-rear direction in the illustrated embodiment. A guide inclined portion 315 is formed at each end of the second extension portion 312 in the extension direction, which is the front-rear direction in the illustrated embodiment.

[0214]

[0239] The second extension 312 partially surrounds the guide hollow 314 from the vertical direction. In the embodiment shown, the second extension 312 surrounds the guide hollow 314 on the upper side.

[0215]

[0240] Thus, the second extension 312 may be said to surround a portion of the vertical exterior of the guide cavity 314 .

[0216]

[0241] The second extension 312 is continuous with the first extension 311 at a predetermined angle. In one embodiment, the predetermined angle may be a right angle.

[0217]

[0242] The second extension portion 312 is disposed so as to face the third extension portion 313 with the guide hollow 314 interposed therebetween.

[0218]

[0243] The third extension 313 forms another part of the guide body 310. In the illustrated embodiment, the third extension 313 forms the other vertical side, i.e., the lower side, of the guide body 310. The third extension 313 is formed to extend in the width direction of the guide body 310, which in the illustrated embodiment is the left-right direction.

[0219]

[0244] The third extension 313 supports the other vertical corner of the capacitor assembly 400 and the associated slot member 500. In the embodiment shown, the third extension 313 supports the lower corner of the capacitor assembly 400 and the associated slot member 500.

[0220]

[0245] Therefore, it can be said that the third extension portion 313 prevents the capacitor assembly 400 that has entered the insertion space S and the slot member 500 coupled thereto from being separated in the vertical direction.

[0221]

[0246] The third extension portion 313 is formed to extend in the extension direction of the guide body 310, which is the front-rear direction in the illustrated embodiment. A guide inclined portion 315 is formed at each end of the third extension portion 313 in the extension direction, which is the front-rear direction in the illustrated embodiment.

[0222]

[0247] The third extension 313 partially surrounds the guide hollow 314 vertically. In the embodiment shown, the third extension 313 surrounds the underside of the guide hollow 314.

[0223]

[0248] Therefore, it can be said that the third extension portion 313 surrounds another part of the vertical outer side of the guide hollow 314.

[0224]

[0249] The third extension 313 is continuous with the first extension 311 at a predetermined angle. In one embodiment, the predetermined angle may be a right angle.

[0225]

[0250] The third extension portion 313 is disposed so as to face the second extension portion 313 with the guide hollow 314 interposed therebetween.

[0226]

[0251] The guide cavity 314 is a space that accommodates the capacitor assembly 400 and the slot member 500 coupled thereto. The guide cavity 314 partially accommodates one side of the capacitor assembly 400 and the slot member 500 coupled thereto.

[0227]

[0252] In the embodiment shown, the guide hollow 314 of the first guide member 300a accommodates a left portion of the capacitor assembly 400 and its associated slot member 500. The guide hollow 314 of the second guide member 300b accommodates a right portion of the capacitor assembly 400 and its associated slot member 500.

[0228]

[0253] The guide hollow 314 is partially surrounded by the first to third extensions 311, 312, 313. In the embodiment shown, the guide hollow 314 is surrounded on one horizontal side by the first extension 311. Both vertical sides of the guide hollow 314 are surrounded by the second extension 312 and the third extension 313, respectively.

[0229]

[0254] One side of the guide hollow 314 in the horizontal direction is open and communicates with the insertion space S. In the illustrated embodiment, the guide hollow 314 of the first guide member 300a is open on the right side and communicates with the insertion space S. The guide hollow 314 of the second guide member 300b is open on the left side and communicates with the insertion space S.

[0230]

[0255] Therefore, it can be said that the guide hollow 314 is formed with an inner side facing the insertion space S open and communicates with the insertion space S.

[0231]

[0256] The guide hollow 314 may extend along the extension direction of the guide body 310. In the illustrated embodiment, the guide hollow 314 is formed to extend in the front-rear direction. Each end of the guide hollow 314 in the extension direction is formed open and communicates with the outside. This allows the capacitor assembly 400 and the slot member 500 coupled thereto to slide along the extension direction of the guide hollow 314.

[0232]

[0257] The cross section of the guide hollow 314 may be of any shape capable of partially accommodating the capacitor assembly 400 and the slot member 500 coupled thereto. In the embodiment shown, the guide hollow 314 is formed to have a rectangular cross section with one side facing the insertion space S being open.

[0233]

[0258] In the above embodiment, the vertical length of the guide hollow 314 may be longer than the height of the capacitor assembly 400 and the slot member 500 coupled thereto. This may provide vertical play for the capacitor assembly 400 inserted into the insertion space S and the slot member 500 coupled thereto. As a result, the vertical swing of the capacitor assembly 400 and the slot member 500 may be damped.

[0234]

[0259] It will be understood that the above-mentioned guide body 310 has a cross section in which one side facing the insertion space S is open, connecting the guide hollow 314 with the insertion space S, and the remaining other side is in the form of a bracket surrounded by the first to third extension parts 311, 312, and 313.

[0235]

[0260] The guide inclined portion 315 guides the capacitor assembly 400 and the slot member 500 coupled thereto entering the guide hollow 314. The guide inclined portion 315 allows the capacitor assembly 400 and the slot member 500 coupled thereto to enter the guide hollow 314 and the insertion space S more smoothly.

[0236]

[0261] The guide inclined portion 315 is formed at an end in the extension direction of the guide body 310. The guide inclined portion 315 may be formed at a plurality of positions. In the illustrated embodiment, the guide inclined portion 315 is formed at each of the front end and the rear end of the guide body 310.

[0237]

[0262] The guide inclined portion 315 may have any shape capable of guiding the capacitor assembly 400 entering the insertion space S and the slot member 500 coupled thereto into the guide hollow 314. In the illustrated embodiment, the guide inclined portion 315 is formed to extend and incline toward the insertion space S in a direction from one end to the other end.

[0238]

[0263] In other words, the guide inclined portion 315 is formed so as to taper in a direction toward the insertion space S.

[0239]

[0264] The guide inclined portion 315 may be formed on each of the first extension portion 311, the second extension portion 312, and the third extension portion 313 that constitute the guide body 310.

[0240]

[0265] In the illustrated embodiment, the guide slope 315 formed in the first extension 311 is extended from the inside to the outside in the horizontal direction along the direction toward the end of the first extension. The guide slope 315 formed in the second extension 312 is extended from the lower side to the upper side along the direction toward the end of the second extension. The guide slope 315 formed in the third extension 313 is extended from the upper side to the lower side along the direction toward the end of the third extension.

[0241]

[0266] Therefore, the capacitor assembly 400 and the slot member 500 coupled thereto are guided by the guide inclined portion 315 and can easily enter the guide hollow 314 and the insertion space S.

[0242]

[0267] The coupling protrusion 320 is a portion where the guide member 300 is coupled to the PCB assembly 200. The coupling protrusion 320 is coupled to the PCB through hole 211 formed through the PCB substrate 210.

[0243]

[0268] The coupling protrusion 320 is formed to extend in a thickness direction of the PCB board 210. One end of the coupling protrusion 320 in the extension direction is located on the lower side of the PCB board 210, and the other end of the coupling protrusion 320 in the extension direction is coupled to the guide body 310 located on the upper side of the PCB board 210.

[0244]

[0269] In the illustrated embodiment, the coupling protrusion 320 is formed to extend in the up-down direction. A lower end of the coupling protrusion 320 penetrates the PCB through-hole 211 and is located on the underside of the PCB board 210. An upper end of the coupling protrusion 320 is coupled to the underside of the guide body 310, i.e., the underside of the extension portion 313.

[0245]

[0270] There may be a plurality of coupling protrusions 320. The coupling protrusions 320 may be spaced apart from one another along the extension direction of the guide body 310. The coupling protrusions 320 may be coupled to the PCB through holes 211 through their respective through holes.

[0246]

[0271] In the illustrated embodiment, three coupling protrusions 320 are provided and spaced apart from each other in the extension direction, i.e., the front-rear direction, of the guide body 310. The number and arrangement of the coupling protrusions 320 can be changed according to the number and arrangement of the PCB through holes 211.

[0247]

[0272] The coupling protrusions 320 may be coupled to the PCB substrate 210 in any manner that allows for a firm coupling with the PCB substrate 210. In the illustrated embodiment, the coupling protrusions 320 may be coupled to the PCB substrate 210 in the form of a snap coupling.

[0248]

[0273] On the other hand, a plurality of coupling protrusions 320 spaced apart from each other may also be formed. That is, a plurality of coupling protrusions 320 may be provided at each position and coupled to the same PCB through-hole 211.

[0249]

[0274] In the illustrated embodiment, the coupling protrusions 320 are provided in a pair, including a first coupling protrusion 320a located on the front side and a second coupling protrusion 320b located on the rear side. The first coupling protrusion 320a and the second coupling protrusion 320b are arranged to face each other at a distance. The distance by which the first coupling protrusion 320a and the second coupling protrusion 320b are separated from each other can be defined as a separation distance g (see FIG. 11).

[0250]

[0275] Therefore, the first and second coupling protrusions 320a and 320b can be moved toward each other by the separation distance g. That is, the first and second coupling protrusions 320a and 320b can be deformed such that their widths in the front-rear direction are reduced by the separation distance g.

[0251]

[0276] As a result, the first coupling protrusion 320a and the second coupling protrusion 320b can be pressed toward each other to be inserted into the PCB through-hole 211, and then can be moved away from each other again when penetrated through the PCB through-hole 211. As a result, the coupling protrusion 320 and the PCB board 210 can be snap-coupled.

[0252]

[0277] In the embodiment shown, the coupling protrusion 320 includes a protrusion extension 321 and a protrusion head 322 .

[0253]

[0278] The protrusion extension 321 forms a body of the coupling protrusion 320. The protrusion extension 321 is a portion of the coupling protrusion 320 that passes through the PCB through hole 211.

[0254]

[0279] The protruding extension 321 is coupled to the guide body 310. In the embodiment shown, the protruding extension 321 has an upper end that is continuous with the lower surface of the third extension 313.

[0255]

[0280] The protrusion extension 321 is coupled to the PCB substrate 210. In the illustrated embodiment, the protrusion extension 321 is coupled to the PCB substrate 210 by being passed through the PCB through hole 211.

[0256]

[0281] The protrusion extension 321 is formed to extend in the thickness direction of the PCB substrate 210, which in the illustrated embodiment is the up-down direction. At this time, the extension length of the protrusion extension 321 may be formed to be longer than the extension length of the PCB through hole 211. In the illustrated embodiment, the extension length of the protrusion extension 321 in the up-down direction is formed to be longer than the extension length of the PCB through hole 211 in the up-down direction.

[0257]

[0282] The above-mentioned structure can ensure a clearance in the thickness direction, i.e., the vertical direction, between the guide member 300 and the PCB assembly 200. As described above, the clearance can buffer the vibration or impact transmitted between the guide member 300 and the PCB assembly 200.

[0258]

[0283] The protrusion extension 321 may have any shape that can penetrate the PCB through hole 211. In the illustrated embodiment, the protrusion extension 321 has a flat surface on one side facing inward (i.e., the direction in which the first coupling protrusion 320a and the second coupling protrusion 320b face each other), and the other side is formed as an outwardly convex curved surface.

[0259]

[0284] A protrusion head portion 322 is provided at one end of the protrusion extension portion 321 in the extension direction opposite to the guide body 310, that is, at the lower end in the illustrated embodiment.

[0260]

[0285] The protruding head portion 322 fixes the guide member 300 to the PCB board 210. The protruding head portion 322 prevents the guide member 300 from being arbitrarily detached from the PCB board 210.

[0261]

[0286] The protrusion head portion 322 is continuous with the protrusion extension portion 321. The protrusion head portion 322 is coupled to one end of the protrusion extension portion 321, in the embodiment shown, the lower end.

[0262]

[0287] The protrusion head 322 is located on one side of the PCB board 210 opposite the guide body 310. In other words, the protrusion head 322 is disposed to face the guide body 310 across the PCB board 210. In the illustrated embodiment, the protrusion head 322 is located on the underside of the PCB board 210.

[0263]

[0288] The protrusion head portion 322 may be formed to have a cross-sectional diameter larger than the cross-sectional diameter of the protrusion extension portion 321. In this case, the protrusion head portion 322 may be formed to be larger than the diameter of the PCB through hole 211 when the coupling protrusion 320 is not pressurized. When the first coupling protrusion 320a and the second coupling protrusion 320b are pressed toward each other, the diameter of the pair of protrusion head portions 322 may be formed to be equal to or smaller than the diameter of the PCB through hole 211.

[0264]

[0289] As a result, in a state in which the first and second coupling protrusions 320a and 320b are pressed toward each other, the pair of protrusion heads 322 may be inserted through the PCB through hole 211. In addition, when the external force applied to the first and second coupling protrusions 320a and 320b is released, the pair of protrusion heads 322 move in opposite directions to each other and are not arbitrarily inserted into the PCB through hole 211.

[0265]

[0290] In summary, the cross-sectional diameter of the pair of protrusion heads 322 is largest when the first coupling protrusion 320a and the second coupling protrusion 320b are not pressed toward each other. Next, the cross-sectional diameter of the pair of protrusion heads 322 when the first coupling protrusion 320a and the second coupling protrusion 320b are pressed toward each other may be equal to or smaller than the cross-sectional diameter of the PCB through hole 211.

[0266]

[0291] Furthermore, the diameter of the pair of protruding extensions 321 may be equal to or smaller than the cross-sectional diameter of the PCB through-hole 211 .

[0267]

[0292] With the above structure, the coupling protrusion 320 can be snap-coupled to the PCB substrate 210 .

[0268]

[0293] The protrusion head portion 322 may be divided into a plurality of portions. The plurality of portions may be formed such that the protrusion head portion 322 is easily inserted into the PCB through hole 211, but is not arbitrarily inserted into the PCB through hole 211 after being inserted into the PCB through hole 211.

[0269]

[0294] In the embodiment shown, the protruding head portion 322 includes a head end portion 322a, a head ramp portion 322b, and a head extension portion 322c.

[0270]

[0295] The head end 322a forms one end of the protruding head portion 322. The head end 322a is the portion that enters the PCB through-hole 211 first when the guide member 300 is coupled to the PCB board 210. In the illustrated embodiment, the head end 322a forms a lower end of the protruding head portion 322.

[0271]

[0296] The head end portion 322a is continuous with the head inclined portion 322b.

[0272]

[0297] The head ramp 322b forms a part of the protruding head 322. In the embodiment shown, the head ramp 322b forms the radial outer side of the protruding head 322. That is, the head ramp 322b of the first coupling protrusion 320a forms the front side of the protruding head 322, and the head ramp 322b of the second coupling protrusion 320b forms the rear side of the protruding head 322.

[0273]

[0298] The head inclined portion 322b may have any shape that allows the coupling protrusion 320 to easily enter the PCB through hole 211. In the illustrated embodiment, the head inclined portion 322b is formed such that the diameter of its cross section decreases as it faces the direction in which the coupling protrusion 320 is inserted into the PCB through hole 211, i.e., downward.

[0274]

[0299] In other words, the head inclined portion 322b extends radially inwardly in a direction toward the head end 322a. Therefore, it will be understood that the cross-sectional area of ​​one side of the head inclined portion 322b toward the head end 322a is smaller than the cross-sectional area of ​​the other side toward the head extension portion 322c.

[0275]

[0300] Therefore, as shown in FIG. 11, the head inclined portion 322b is formed to extend downward from the outer side to the inner side.

[0276]

[0301] As a result, after the first coupling protrusion 320a and the second coupling protrusion 320b are pressed toward each other, the head inclined portion 322b can be guided by the inner surface of the PCB substrate 210 surrounding the PCB through hole 211 and penetrated into the PCB through hole 211.

[0277]

[0302] The head inclined portion 322b is continuous with the head extension portion 322c.

[0278]

[0303] The head extension 322c forms the other end of the protruding head portion 322. The head extension 322c is the portion that is located closest to the PCB substrate 210 after the protruding head portion 322 is pulled out of the PCB through-hole 211. In the embodiment shown, the head extension 322c forms the upper side of the protruding head portion 322.

[0279]

[0304] The head extension portion 322c is coupled to the one end portion in the extension direction of the protruding extension portion 321, which is the lower end portion in the illustrated embodiment.

[0280]

[0305] The head extension 322c extends radially inward at a predetermined angle with the head ramp 322b. In the embodiment shown, the head extension 322c extends radially inward at an acute angle with the head ramp 322b.

[0281]

[0306] In the embodiment shown, the radially outer end of the head extension 322c is continuous with the head ramp portion 322b. The radially inner end of the head extension 322c is continuous with the lower end of the protrusion extension 321.

[0282]

[0307] The head extension 322c may contact a lower surface of the PCB substrate 210 that radially outwardly surrounds the PCB through-hole 211. In one embodiment, the head extension 322c may extend parallel to the PCB substrate 210.

[0283]

[0308] As a result, after the coupling protrusion 320 penetrates and is pulled out of the PCB through hole 211, unless an external force is applied to the first coupling protrusion 320a and the second coupling protrusion 320b, the coupling protrusion 320 cannot be arbitrarily pulled into the PCB through hole 211. As a result, the coupling state between the guide member 300 and the PCB assembly 200 can be stably maintained.

[0284]

[0309]

[0310] 2 and 3, the power electronics 10 according to the illustrated embodiment includes a capacitor assembly 400.

[0285]

[0311] The capacitor assembly 400 includes a capacitor 410 and provides electrical power for the PCB assembly 200 and, in turn, the power electronics 10 to operate.

[0286]

[0312] In particular, the capacitor assembly 400 according to the embodiment of the present invention is provided in a modular form and is detachably coupled to the PCB assembly 200. That is, the capacitor assembly 400 is provided separately from the PCB assembly 200.

[0287]

[0313] Therefore, when maintenance of the capacitor 410 is required, only the capacitor assembly 400 can be separated without a separation process of the entire PCB assembly 200.

[0288]

[0314] In addition, the capacitor assembly 400 can be maintained in a state where it is coupled to the housing 100 and the PCB assembly 200 without a separate fastening member, thereby reducing the number of members and steps required to couple the capacitor assembly 400 to other members.

[0289]

[0315] The capacitor assembly 400 is removably inserted and coupled to the housing 100. The capacitor assembly 400 can be drawn into the accommodation space 104 of the housing 100 through the insertion opening 110.

[0290]

[0316] The capacitor assembly 400 is electrically connected to the PCB assembly 200. The capacitor connector 430 of the capacitor assembly 400 can be inserted into and coupled to the connector 220 of the PCB assembly 200 to electrically connect to the PCB assembly 200.

[0291]

[0317] The movement of the capacitor assembly 400 is guided by the guide member 300. Specifically, the capacitor assembly 400 is housed in the guide hollow 314 of the guide member 300 and can slide along the extension direction of the guide member 300. At this time, a pair of corners of the capacitor assembly 400 can be guided by the first extension portion 311, the second extension portion 312, and the third extension portion 313.

[0292]

[0318] In the embodiment shown, the capacitor assembly 400 may be supported by the guide member 300 such that its left and right corners are received in the guide hollows 314 and are slidable forward and rearward.

[0293]

[0319] The capacitor assembly 400 is coupled to the slot member 500. The capacitor assembly 400 is detachably coupled to the slot member 500 and can be moved together with the slot member 500. This not only allows the capacitor assembly 400 to move smoothly, but also enhances the rigidity of the capacitor assembly 400, particularly the capacitor substrate 420. This will be described in detail later.

[0294]

[0320] In the illustrated embodiment, there is provided a single capacitor assembly 400 and a single slot member 500 coupled to the capacitor assembly 400. Alternatively, there may be provided a plurality of capacitor assemblies 400 and a single slot member 500. The plurality of capacitor assemblies 400 and the slot members 500 coupled thereto may each be retractably accommodated in the housing 100 and provided so as to be electrically connected to the PCB assembly 200.

[0295]

[0321] In the above embodiment, when maintenance is required for one of the plurality of capacitor assemblies 400, only the capacitor assembly 400 may be pulled out and the work performed thereon. That is, the maintenance of the capacitor assembly 400 does not require the entire power electronic device 10 to be shut down.

[0296]

[0322] 12-14, the illustrated embodiment includes a capacitor 410, a capacitor substrate 420, and a capacitor connector 430.

[0297]

[0323] The capacitor 410 is charged by an external power source to store power. The capacitor 410 is electrically connected to the PCB assembly 200 to transfer the stored power. The power electronic device 10 can be operated by the power.

[0298]

[0324] The capacitor 410 is electrically connected to a capacitor substrate 420. The power stored in the capacitor 410 can be transferred to the PCB assembly 200 via the capacitor substrate 420 and a capacitor connector 430 electrically connected thereto.

[0299]

[0325] The capacitor 410 is removably coupled to the capacitor substrate 420. In other words, the capacitor 410 is fabricated separately from the capacitor substrate 420 and then coupled to the capacitor substrate 420.

[0300]

[0326] Therefore, when maintenance of the capacitor 410 is required, only the capacitor 410 can be separated from the capacitor substrate 420 and maintained or replaced. As a result, the capacitor substrate 420 without any abnormality can be used as it is, improving the convenience of the work and reducing time and monetary costs.

[0301]

[0327] The capacitor 410 may be provided in any form capable of being charged by an external power source, storing power, and transferring the stored power to the PCB assembly 200. In the embodiment shown, the capacitor 410 is cylindrical in shape having a circular cross section and elongated in the front-to-rear direction.

[0302]

[0328] In an embodiment in which the capacitor 410 has a cylindrical shape, the capacitor 410 may be coupled to the capacitor substrate 420 so as to partially penetrate the capacitor substrate 420. That is, in the embodiment shown in Fig. 12, a portion of a lower portion of the outer periphery of the capacitor 410 may be penetrated by an opening (not shown in the drawing) formed in the capacitor substrate 420, and the remaining portion of the lower portion may be supported by the upper surface of the capacitor substrate 420 surrounding the opening.

[0303]

[0329] A plurality of capacitors 410 may be provided. The plurality of capacitors 410 may be coupled to the capacitor substrate 420 and may be electrically connected to the capacitor substrate 420. In the illustrated embodiment, four capacitors 410 are provided. Of the four capacitors 410, one pair of capacitors 410 is biased toward the front side, and the other pair of capacitors 410 is biased toward the rear side.

[0304]

[0330] In one embodiment, the capacitors 410 may be formed to extend in the same direction as the extension direction of the capacitor substrate 420 and may be arranged side by side along the extension direction. In the illustrated embodiment, the capacitors 410 are formed to have a longer extension length in the front-rear direction, similar to the capacitor substrate 420, and are arranged side by side along the front-rear direction.

[0305]

[0331] It will be understood that the extension direction of the capacitor 410 and the capacitor substrate 420 is the same as the direction in which the capacitor assembly 400 and the slot member 500 are retracted or withdrawn into the housing 100 .

[0306]

[0332] The capacitor substrate 420 transfers the power stored in the capacitor 410 to the PCB assembly 200. Thus, it can be said that the capacitor substrate 420 electrically connects the capacitor 410 and the PCB assembly 200.

[0307]

[0333] The capacitor substrate 420 is coupled to the capacitor 410. In the embodiment shown, the capacitor substrate 420 is coupled to the underside of the capacitor 410 to support the capacitor substrate 420.

[0308]

[0334] As described above, in an embodiment in which the capacitor 410 is provided in a cylindrical shape, the capacitor substrate 420 may have an opening formed therethrough at a position corresponding to the capacitor 410. The opening may be configured to partially accommodate a portion of the capacitor 410, in the illustrated embodiment, a portion of the lower side. At the same time, the portion of the capacitor 410 may be accommodated in a capacitor accommodating portion 524 formed in the slot member 500.

[0309]

[0335] The capacitor substrate 420 is electrically connected to the capacitor 410. The power stored in the capacitor 410 can be transferred to the capacitor substrate 420.

[0310]

[0336] The capacitor substrate 420 may include a number of electrical elements that may be coupled to the capacitor substrate 420. The capacitor substrate 420 may receive control signals to control the capacitor 410 and the transfer of power.

[0311]

[0337] The capacitor substrate 420 is electrically connected to the capacitor connector 430. Power transferred to the capacitor substrate 420 can be transferred to the PCB assembly 200 via the capacitor connector 430.

[0312]

[0338] The capacitor board 420 is coupled to the slot member 500. More specifically, a portion of the capacitor board 420 is supported by a capacitor support portion 530 formed on a slot body 520 of the slot member 500. In addition, the other portion of the capacitor board 420 is supported by a locking protrusion 540. This will be described in detail later.

[0313]

[0339] The capacitor substrate 420 may be formed in a shape corresponding to the slot member 500. In the illustrated embodiment, the capacitor substrate 420 is formed in a rectangular plate shape having a length in the front-rear direction longer than a length in the left-right direction and a thickness in the up-down direction. As described above, the direction in which the capacitor substrate 420 extends further is the same as the direction in which the capacitor assembly 400 is drawn into or drawn out of the accommodating space 104.

[0314]

[0340] In the embodiment shown, the capacitor substrate 420 includes a first corner 421 , a second corner 422 , a third corner 423 , a fourth corner 424 , a support space 425 , and a support extension 426 .

[0315]

[0341] The first corner 421 forms one corner of the capacitor substrate 420. In the illustrated embodiment, the first corner 421 forms a rear corner of the capacitor substrate 420. The first corner 421 is formed to extend in the width direction of the capacitor substrate 420, which in the illustrated embodiment is the left-right direction.

[0316]

[0342] The first corner 421 is located adjacent to the gripping portion 510 of the slot member 500. The first corner 421 is supported by the gripping portion 510 in the extension direction of the capacitor substrate 420, which is the front-rear direction in the illustrated embodiment.

[0317]

[0343] First corner 421 is disposed to face second corner 422 across capacitor 410 and an opening that partially accommodates capacitor 410. First corner 421 is continuous with third corner 423 and fourth corner 424.

[0318]

[0344] The second corner 422 forms another corner of the capacitor substrate 420. In the illustrated embodiment, the second corner 422 forms a front corner of the capacitor substrate 420. The second corner 422 extends in the width direction of the capacitor substrate 420, which in the illustrated embodiment is the left-right direction.

[0319]

[0345] The second corner 422 is located adjacent to the locking protrusion 540 of the slot member 500. The second corner 422 is supported by the locking protrusion 540 in the extension direction of the capacitor substrate 420, that is, in the front-rear direction in the illustrated embodiment.

[0320]

[0346] Therefore, when the capacitor assembly 400 is pulled into the housing 100 , the first corner portion 421 is supported by the gripping portion 510 , and the capacitor connector 430 can be inserted into the connector 220 and pulled into the housing 100 .

[0321]

[0347] Furthermore, when the capacitor assembly 400 is pulled out from the housing 100 , the second corner 422 is supported by the locking protrusion 540 , and the capacitor connector 430 is separated from the connector 220 and can be pulled out from the housing 100 .

[0322]

[0348] Second corner 422 is disposed to face first corner 421 across capacitor 410 and an opening that partially accommodates capacitor 410. Second corner 422 is continuous with third corner 423 and fourth corner 424.

[0323]

[0349] The third corner 423 forms the other corner of the capacitor substrate 420. In the embodiment shown, the third corner 423 forms the left corner of the capacitor substrate 420. The third corner 423 is formed to extend in the longitudinal direction of the capacitor substrate 420, which in the embodiment shown is the front-rear direction.

[0324]

[0350] The third corner 423 is positioned adjacent to the first wall 521 of the slot member 500. The third corner 423 is partially supported by the first wall 521.

[0325]

[0351] The third corner 423 is detachably coupled to the capacitor support 530. Specifically, the third corner 423 is supported by a support protrusion 532 of the capacitor support 530 located on the left side in a direction toward the slot member 500, that is, in the illustrated embodiment, on the lower side.

[0326]

[0352] Third corner 423 is disposed to face fourth corner 424 across capacitor 410 and an opening that partially accommodates capacitor 410. Third corner 423 is continuous with first corner 421 and second corner 422.

[0327]

[0353] The fourth corner 424 forms another corner of the capacitor substrate 420. In the illustrated embodiment, the fourth corner 424 forms a right corner of the capacitor substrate 420. The fourth corner 424 is formed to extend in the longitudinal direction of the capacitor substrate 420, which in the illustrated embodiment is the front-rear direction.

[0328]

[0354] The fourth corner 424 is located adjacent to the second wall 522 of the slot member 500. The fourth corner 424 is partially supported by the second wall 522. Specifically, the fourth corner 424 is supported by a support protrusion 532 of a capacitor support portion 530 located on the right side, which supports the fourth corner 424 in a direction toward the slot member 500, that is, in the illustrated embodiment, downward.

[0329]

[0355] Fourth corner 424 is disposed to face third corner 423 across capacitor 410 and an opening that partially accommodates capacitor 410. Fourth corner 424 is continuous with first corner 421 and second corner 422.

[0330]

[0356] The support space 425 is a space in which the locking protrusion 540 of the slot member 500 is accommodated. The support space 425 is located adjacent to one end in the extension direction of the capacitor substrate 420, which is adjacent to the front end in the illustrated embodiment. In other words, the support space 425 is located adjacent to the second corner 422.

[0331]

[0357] The support space 425 may be partially surrounded by the second corner portion 422, the capacitor connector 430, and the support extension portion 426, respectively.

[0332]

[0358] In the illustrated embodiment, the rear side of the support space 425 is bounded by the second corner 422. The inside of the support space 425 (i.e., the right side of the left support space 425 and the left side of the right support space 425) is bounded by the capacitor connector 430. Additionally, the outside of the support space 425 (i.e., the left side of the left support space 425 and the right side of the right support space 425) is bounded by the support extension 426.

[0333]

[0359] Another portion of the support space 425, which is the front side in the illustrated embodiment, is open. The locking projection 540 can enter the support space 425 through the open portion of the support space 425, which is the front side in the illustrated embodiment.

[0334]

[0360] A plurality of support spaces 425 may be formed. The plurality of support spaces 425 can accommodate the locking protrusions 540 at different positions. In the illustrated embodiment, the support spaces 425 are formed on the left and right sides, respectively. In other words, the pair of support spaces 425 are disposed to face each other in the width direction of the capacitor substrate 420 with the capacitor connector 430 interposed therebetween.

[0335]

[0361] That is, the multiple support spaces 425 are partitioned by the capacitor connectors 430 .

[0336]

[0362] The support space 425 is partially surrounded by a support extension 426 .

[0337]

[0363] The support extension portion 426 partially surrounds the support space portion 425 together with the second corner portion 422 and the capacitor connector 430. The locking protrusion 540 accommodated in the support space portion 425 can be stably maintained in the support space portion 425 by the support extension portion 426.

[0338]

[0364] The support extension 426 is continuous with the second corner 422. The support extension 426 extends from the second corner 422 at an angle relative to the second corner 422. In the embodiment shown, the support extension 426 extends perpendicular to the second corner 422 toward the front side.

[0339]

[0365] There may be a plurality of support extensions 426. The plurality of support extensions 426 may be spaced apart from one another and extend at different locations from the second corner 422. In the embodiment shown, a pair of support extensions 426 are provided.

[0340]

[0366] In the embodiment, any one of the support extensions 426 extends toward the front side from one end in the extension direction of the second corner 422, which in the embodiment shown is the left end. The other support extension 426 extends toward the front side from the other end in the extension direction of the second corner 422, which in the embodiment shown is the right end.

[0341]

[0367] In one embodiment, the extension length of the support extension 426 may be the same as the extension length of the capacitor connector 430. That is, the end of the extension direction of the support extension 426 may be located on the same line as the end of the extension direction of the capacitor connector 430.

[0342]

[0368] The support extension 426 surrounds the support space 425 from the outside in the width direction. In an embodiment in which a pair of support extensions 426 is provided, the support extension 426 located on the left side surrounds the left side of the support space 425 located on the left side. In the embodiment, the support extension 426 located on the right side surrounds the right side of the support space 425 located on the right side.

[0343]

[0369] Furthermore, the support extensions 426 surround the connector 220, to which the capacitor connector 430 is coupled, from the outside in the width direction. In the illustrated embodiment, the support extension 426 located on the left side surrounds the left side of the connector 220, and the support extension 426 located on the right side surrounds the right side of the connector 220.

[0344]

[0370] The pair of support extensions 426 are located at a predetermined distance apart from each other in the width direction, or in the left-right direction in the illustrated embodiment, of the capacitor substrate 420. In one embodiment, the shortest distance between the pair of support extensions 426 may be greater than or equal to the width of the connector 220 of the PCB assembly 200, i.e., the left-right length.

[0345]

[0371] A capacitor connector 430 is located between the pair of support extensions 426 .

[0346]

[0372] The capacitor connector 430 is a portion where the capacitor assembly 400 is electrically connected to the PCB assembly 200. The capacitor connector 430 is coupled to the connector 220 of the PCB assembly 200 and is electrically connected to the connector 220.

[0347]

[0373] The power stored in the capacitor 410 can be transferred to the PCB assembly 200 via the capacitor substrate 420 and the capacitor connector 430 .

[0348]

[0374] The capacitor connector 430 is connected to the capacitor substrate 420. The capacitor connector 430 is located at one end in the extension direction of the capacitor substrate 420, which is the front end in the illustrated embodiment. The capacitor connector 430 is electrically connected to the capacitor substrate 420.

[0349]

[0375] The capacitor connector 430 extends in a direction opposite to the one end of the capacitor board 420, toward the front side in the illustrated embodiment. One end of the capacitor connector 430 in the extension direction, that is, the front end in the illustrated embodiment, may be located on the same line in the left-right direction as one end of the support extension 426, that is, the front end in the illustrated embodiment.

[0350]

[0376] In other words, the extension lengths of the capacitor connector 430 and the support extension 426 may be the same.

[0351]

[0377] The connector 220 may be located on an imaginary straight line extending in the extension direction of the capacitor connector 430. Thus, the capacitor connector 430 and the connector 220 may be coupled together simply by sliding the capacitor assembly 400 toward the connector 220.

[0352]

[0378] A pair of support spaces 425 are formed in the width direction of the capacitor connector 430, which is the left-right direction in the illustrated embodiment. The connector 220 is partially accommodated in the pair of support spaces 425, and can be coupled to the capacitor connector 430 and electrically connected thereto.

[0353]

[0379] The capacitor connector 430 may be provided in any form that allows it to be detachably coupled to the connector 220. In the embodiment shown, the capacitor connector 430 may be removably inserted into the connector 220 that is provided in a slot form.

[0354]

[0380]

[0381] 2 and 3, the power electronics 10 according to the illustrated embodiment includes a slot member 500.

[0355]

[0382] The slot member 500 supports the capacitor assembly 400. Moreover, the slot member 500, together with the capacitor assembly 400, is supported by the guide member 300 and is accommodated in the housing 100 so as to be removable.

[0356]

[0383] In particular, the slot member 500 according to the embodiment of the present invention includes components for coupling with the capacitor assembly 400 and components for coupling with the housing 100. The slot member 500 can be detachably coupled to the capacitor assembly 400 and the housing 100, respectively, by the above-mentioned components without a separate fastening member.

[0357]

[0384] At this time, an external force must be applied by an operator in order for the slot member 500 to be detached from the capacitor assembly 400 or the housing 100. In other words, unless another external force is applied to the slot member 500, the slot member 500 remains coupled to the capacitor assembly 400 or the housing 100.

[0358]

[0385] Therefore, the slotted member 500 can be easily coupled to the capacitor assembly 400 or the housing 100 without a separate tool or fastener. Furthermore, the slotted member 500 can be easily separated from the capacitor assembly 400 or the housing 100 without a separate tool.

[0359]

[0386] The slot member 500 is removably inserted and coupled to the housing 100. The slot member 500 can be pulled into the accommodation space 104 of the housing 100 through the insertion opening 110. The slot member 500 can also be detachably coupled to the support frame 120.

[0360]

[0387] The movement of the slot member 500 is guided by the guide member 300. Specifically, the corner of the extension direction of the slot member 500 may be partially housed in the guide hollow 314 of the guide member 300. The slot member 500 may be slid along the extension direction of the guide member 300, and may be pulled into or pulled out of the housing 100.

[0361]

[0388] At this time, the corner of the slot member 500 can be guided by the first extension portion 311 , the second extension portion 312 , and the third extension portion 313 .

[0362]

[0389] The slot member 500 is coupled to the capacitor assembly 400. The slot member 500 supports the capacitor assembly 400 on one side, in the illustrated embodiment, the underside, but may be disposed to surround some of the corners. In the illustrated embodiment, the slot member 500 is coupled to the capacitor assembly 400 surrounding the first corner 421, the third corner 423, and the fourth corner 424 of the capacitor assembly 400.

[0363]

[0390] In the embodiment shown, the slot member 500 is fabricated separately from the capacitor assembly 400, provided therewith, and coupled to the capacitor assembly 400. Alternatively, the slot member 500 may be integrally formed with the capacitor assembly 400.

[0364]

[0391] For example, the capacitor assembly 400 and the slot member 500 may be formed such that the capacitor substrate 420 and the capacitor connector 430 are integrally formed with the slot member 500, and then the capacitor 410 is coupled to and energized with the capacitor substrate 420.

[0365]

[0392] In the illustrated embodiment, a single capacitor assembly 400 and a single slot member 500 are provided, however, as described above, a corresponding number of capacitor assemblies 400 and slot members 500 may alternatively be provided.

[0366]

[0393] 12-14 and 15-17, the slot member 500 according to the illustrated embodiment includes a gripping portion 510, a slot body 520, a capacitor support portion 530, and a locking protrusion 540. As shown in FIG.

[0367]

[0394] The grip portion 510 is a portion of the slot member 500 that is operated by an operator. When the slot member 500 is coupled to the housing 100, the grip portion 510 is exposed to the outside of the housing 100. An operator can grip the exposed grip portion 510 to couple the slot member 500 and the capacitor assembly 400 coupled thereto to the housing 100 or pull them out from the housing 100.

[0368]

[0395] The gripping portion 510 forms one end in the extension direction of the slot member 500. The one end can be defined as the end in the direction opposite to the housing 100 or the PCB assembly 200. In the embodiment shown, the gripping portion 510 forms the rear end of the slot member 500 extending in the front-rear direction.

[0369]

[0396] The grip portion 510 is detachably coupled to the housing 100 and may have any shape that can be externally identified by an operator. In the illustrated embodiment, the grip portion 510 is formed in a polygonal plate shape having a greater extension length in the left-right direction than in the up-down direction and a greater thickness in the front-rear direction.

[0370]

[0397] The shape of the gripping portion 510 may be modified to correspond to the shape of the insertion opening 110 and the support frame 120 surrounding it.

[0371]

[0398] The grip portion 510 may be partially housed in the insertion opening 110 and the grip space 130. In addition, the grip portion 510 may be detachably coupled to the support frame 120, and the coupled state of the grip portion 510 and the housing 100 may be maintained unless an external force is applied. This will be described in detail later.

[0372]

[0399] When grip portion 510 is received in insertion opening 110, the outer surface of grip portion 510 and the outer surface of housing 100, in the illustrated embodiment, the rear side surface, may be located on the same plane. That is, grip portion 510 is positioned so as not to protrude relative to the outer surface of housing 100.

[0373]

[0400] This can improve the degree of freedom in arranging the power electronic device 10.

[0374]

[0401] In the illustrated embodiment, a plurality of ribs extending in the height direction, i.e., the vertical direction, are formed on the outer surface of the grip portion 510. The ribs reinforce the rigidity of the grip portion 510 and also provide a unified appearance with the outer surface of the housing 100.

[0375]

[0402] In the illustrated embodiment, the gripping portion 510 includes a gripping body 511 , a pressure protrusion 512 , an insertion protrusion 513 , and an identification recess 514 .

[0376]

[0403] The grip body 511 forms a body of the grip portion 510. The grip body 511 is a portion where the grip portion 510 is coupled to the slot body 520. In addition, the grip body 511 is a portion where the slot member 500 accommodated in the housing 100 is exposed to the outside.

[0377]

[0404] The grip body 511 is accommodated in the insertion opening 110. The grip body 511 is disposed so as to be surrounded by the support frame 120 that surrounds the insertion opening 110.

[0378]

[0405] The grip body 511 may be formed in a shape corresponding to the shape of the grip portion 510. In the illustrated embodiment, the grip body 511 is formed in a polygonal plate shape having a left-right extension length longer than a top-bottom extension length and a width in the front-back direction.

[0379]

[0406] In this case, the grip body 511 may be formed to have a structure that is symmetrical in its width direction, which is the left-right direction in the embodiment shown. Also, the grip body 511 may be formed to have a structure that is asymmetrical in its height direction, which is the up-down direction in the embodiment shown. The asymmetry may be formed by the identification recess 514.

[0380]

[0407] Therefore, the operator can easily recognize the insertion direction of slot member 500 and capacitor assembly 400 coupled thereto through the shape of grip body 511.

[0381]

[0408] The gripping body 511 is coupled to the slotted body 520. In the embodiment shown, the front end of the gripping body 511 is coupled to the rear end of the slotted body 520.

[0382]

[0409] A plurality of ribs may be formed on the outer surface of the grip body 511, in the illustrated embodiment, on the rear side surface. The plurality of ribs may be spaced apart from one another to reinforce the rigidity of the grip body 511 and to form a uniform appearance with the outer surface of the housing 100.

[0383]

[0410] A pressure projection 512 is formed on each end of the grip body 511 in the width direction, that is, on the left end and the right end in the illustrated embodiment.

[0384]

[0411] The pressure protrusion 512 is deformed by pressure applied by an operator. The pressure protrusion 512 is connected to the insertion protrusion 513, and when the pressure protrusion 512 is deformed by pressure applied, the insertion protrusion 513 can be separated from the support frame 120. As a result, the coupling state between the grip portion 510 and the support frame 120 is released, and the slot member 500 and the capacitor assembly 400 coupled thereto can be pulled out from the housing 100.

[0385]

[0412] The pressure projection 512 is coupled to the grip body 511. A plurality of pressure projections 512 may be provided, and the pressure projections 512 may be located at each end in the extension direction of the grip body 511. In the illustrated embodiment, a pair of pressure projections 512 are provided, and are located at the left end and the right end of the grip body 511, respectively.

[0386]

[0413] In a state where no external force is applied, the pressure protrusion 512 may be located at a predetermined distance away from the grip body 511. When an external force is applied, the pressure protrusion 512 may be moved toward the end of the grip body 511. In other words, the pressure protrusion 512 is moved inward by the applied external force.

[0387]

[0414] At this time, the insertion protrusions 513 connected to the pressure protrusions 512 are also moved in the same direction, that is, toward the inside, so that the connection with the support frame 120 can be released.

[0388]

[0415] When the slot member 500 is coupled to the housing 100 , the insertion protrusions 513 are pressed by the support frame 120 and moved inwardly toward the receiving space 104 of the housing 100 .

[0389]

[0416] At this time, the pressure protrusion 512 coupled with the insertion protrusion 513 is moved inward by the pressure and maintained in a pressurized state. When the slot member 500 is completely inserted, the pressing state of the insertion protrusion 513 by the support frame 120 is released, and the pressure protrusion 512 can return to the position before the pressure was applied.

[0390]

[0417] The pressure protrusion 512 may be made of a material having a predetermined elasticity. The pressure protrusion 512 may be made of any material that can be deformed by an external force, store a restoring force, and return to its original shape when the applied external force is released. In one embodiment, the pressure protrusion 512 may be made of a synthetic resin material such as polycarbonate-acrylonitrile-butadiene-styrene (PC-ABS).

[0391]

[0418] The pressure protrusion 512 is accommodated in the gripping space 130 of the housing 100. The pressure protrusion 512 is accommodated in the gripping space 130 and does not protrude from the outer surface of the housing 100. As a result, the pressure protrusion 512 may not be arbitrarily pressurized during the process of installing and moving the power electronic device 10.

[0392]

[0419] In an embodiment in which a plurality of pressure protrusions 512 are provided, the plurality of pressure protrusions 512 may be accommodated in the plurality of gripping spaces 130, respectively. In the embodiment shown, the pressure protrusion 512 located on the left side is accommodated in the first gripping space 131, and the pressure protrusion 512 located on the rear side is accommodated in the second gripping space 132.

[0393]

[0420] The pressure protrusion 512 may be formed in any shape that can be coupled to and move together with the insertion protrusion 513. In the illustrated embodiment, the pressure protrusion 512 is formed such that the width of one side facing the outer surface of the grip body 511, i.e., the rear side, is larger than the width of the front side, and the insertion protrusion 513 is coupled to the outer side in the width direction of the front side.

[0394]

[0421] The insertion protrusion 513 is moved together with the pressure protrusion 512 to couple or separate the slotted member 500 to the housing 100. The insertion protrusion 513 is coupled with the pressure protrusion 512.

[0395]

[0422] The insertion protrusion 513 is formed to protrude from the outer surface of the pressure protrusion 512. As described above, the pressure protrusion 512 includes a surface that is formed to extend in the extension direction of the slot member 500, that is, in the front-rear direction in the illustrated embodiment. The insertion protrusion 513 is formed to protrude outward from the surface.

[0396]

[0423] A plurality of insertion protrusions 513 may be formed. The plurality of insertion protrusions 513 may be coupled to the plurality of pressure protrusions 512, respectively, and moved together with the plurality of pressure protrusions 512. In the embodiment shown, a pair of insertion protrusions 513 are provided, and each of the insertion protrusions 513 may be coupled to a pair of pressure protrusions 512 and moved together.

[0397]

[0424] The insertion protrusion 513 may be disposed at a predetermined position in the extension direction of the pressure protrusion 512, which in the illustrated embodiment is the front-rear direction. In one embodiment, the distance between the insertion protrusion 513 and the outer (i.e., in the illustrated embodiment, the rear side) end of the pressure protrusion 512 may be formed to be equal to or greater than the thickness of the support frame 120 (i.e., in the illustrated embodiment, the length in the front-rear direction).

[0398]

[0425] Therefore, when the insertion of the slot member 500 starts, the insertion protrusion 513 is pressed and moved by the support frame 120. When the slot member 500 is sufficiently inserted, that is, when it is inserted by the distance between the insertion protrusion 513 and the outer end of the pressure protrusion 512, the pressing state by the support frame 120 is released.

[0399]

[0426] As a result, the insertion protrusion 513 is moved inward while wrapping around the inner end of the support frame 120, in the illustrated embodiment, the front end. The movement allows the insertion protrusion 513 to be coupled with the support frame 120.

[0400]

[0427] Therefore, it may be said that the insertion projections 513 and the support frame 120 are a snap fit.

[0401]

[0428] The insertion protrusion 513 may have any shape that can be detachably coupled to the support frame 120. In the illustrated embodiment, the insertion protrusion 513 is formed such that the extension length in the up-down direction is longer than the extension length in the left-right direction and has a thickness in the left-right direction. In this case, each corner of the insertion protrusion 513 is chamfered (tapered) so that it can be easily coupled to and separated from the support frame 120.

[0402]

[0429] A detailed description of the process in which the slot member 500 and the capacitor assembly 400 coupled thereto are coupled to and separated from the housing 100 by operating the pressure protrusions 512 and the insertion protrusions 513 will be given later.

[0403]

[0430] The identification recess 514 is a portion that is identified by an operator to recognize the insertion direction of the slot member 500 and the capacitor assembly 400 coupled thereto. The identification recess 514 is disposed to be aligned with the identification protrusion 125 of the support frame 120.

[0404]

[0431] The identification recess 514 is recessed at one corner of the grip body 511. The identification recess 514 may be formed in a shape corresponding to the shape of the identification protrusion 125 of the support frame 120.

[0405]

[0432] In the illustrated embodiment, the identification protrusion 125 protrudes from the fourth portion 124 toward the insertion opening 110. Thus, the identification recess 514 is recessed into an upper corner of the grip body 511 in the illustrated embodiment so as to correspond to the position and shape of the identification protrusion 125.

[0406]

[0433] The identification recess 514 and the identification protrusion 125 may be formed to be complementary to one another. That is, in the embodiment shown, the identification protrusion 125 is formed in the housing 100 and the identification recess 514 is formed in the slot member 500. Alternatively, the identification recess 514 may be formed in the housing 100 and the identification protrusion 125 in the slot member 500.

[0407]

[0434] In either case, it is sufficient if the worker can easily identify the insertion direction of the slot member 500 and the capacitor assembly 400 coupled thereto, that is, the up-down direction.

[0408]

[0435] The slot body 520 forms a body of the slot member 500. The slot body 520 is coupled to the capacitor assembly 400 and supports the capacitor assembly 400. The slot body 520 is guided by the guide member 300 and can be retractably accommodated in the housing 100.

[0409]

[0436] The slot body 520 extends in the same direction as the capacitor assembly 400, which in the illustrated embodiment is the front-to-rear direction. It will be understood that the extension direction is the same as the direction in which the slot member 500 and the capacitor assembly 400 coupled thereto are retracted or pulled out of the housing 100.

[0410]

[0437] The slot body 520 may be formed of a material having a certain elasticity in order to be deformed by pressure from the capacitor assembly 400 and to be coupled to the capacitor assembly 400. In addition, the slot body 520 may be deformed by application of an external force and may be separated from the coupled capacitor assembly 400.

[0411]

[0438] In one embodiment, the slot body 520 may be made of a synthetic resin material such as PC-ABS.

[0412]

[0439] The slot body 520 is located in an insertion space S formed between the guide members 300. The slot body 520 can be retracted or pulled into the insertion space S in the direction in which the guide member 300 extends, in the forward and backward directions in the illustrated embodiment.

[0413]

[0440] The slot body 520 may be formed in a shape corresponding to the capacitor substrate 420. In the illustrated embodiment, the slot body 520 is formed in a rectangular plate shape having a length in the front-rear direction longer than a length in the left-right direction and a width in the up-down direction. A space surrounded by the gripping portion 510, the multiple walls, and the locking protrusion 540 is formed inside the slot body 520. The capacitor assembly 400 may be accommodated in the space.

[0414]

[0441] In the embodiment shown, the slot body 520 includes a first wall 521 , a second wall 522 , a third wall 523 , and a capacitor housing portion 524 .

[0415]

[0442] The first wall 521 forms one of the outer corners of the slot body 520. The first wall 521 is formed to extend in the lengthwise direction of the slot body 520 and supports the capacitor assembly 400 coupled to the slot body 520 at one side. In the illustrated embodiment, the first wall 521 forms a left wall of the slot body 520. In the embodiment, the first wall 521 is formed to extend in the front-rear direction.

[0416]

[0443] The first wall 521 is coupled to the second guide member 300b of the guide member 300. The first wall 521 can be slid along the extension direction of the guide body 310 in a state where it is inserted into the guide hollow 314 of the second guide member 300b.

[0417]

[0444] The first wall 521 is formed to extend a predetermined length in the slot body 520 in a direction toward the capacitor assembly 400. In the illustrated embodiment, the first wall 521 is formed to extend a predetermined length upward and surround a third corner 423 of the capacitor substrate 420 accommodated in the space.

[0418]

[0445] The first wall 521 is disposed so as to be surrounded by the pair of capacitor support portions 530. In the illustrated embodiment, the first wall 521 is disposed alternately with the pair of capacitor support portions 530 along its extension direction, i.e., the front-rear direction.

[0419]

[0446] The first wall 521 is disposed so as to face the second wall 522 across the space.

[0420]

[0447] The second wall 522 forms another of the outer corners of the slot body 520. The second wall 522 is formed to extend in the longitudinal direction of the slot body 520 to support the other side of the capacitor assembly 400 coupled to the slot body 520. In the illustrated embodiment, the second wall 522 forms a right side wall of the slot body 520. In the embodiment, the second wall 522 is formed to extend in the front-rear direction.

[0421]

[0448] The second wall 522 is coupled to the first guide member 300a of the guide member 300. The second wall 522 can be slid along the extension direction of the guide body 310 in a state where it is inserted into the guide hollow 314 of the first guide member 300a.

[0422]

[0449] The second wall 522 is formed to extend a predetermined length in the slot body 520 in a direction toward the capacitor assembly 400. In the illustrated embodiment, the second wall 522 is formed to extend a predetermined length upward and surround a fourth corner 424 of the capacitor substrate 420 accommodated in the space.

[0423]

[0450] The second wall 522 is disposed so as to be surrounded by the pair of capacitor support portions 530. In the illustrated embodiment, the second wall 522 is disposed alternately with the pair of capacitor support portions 530 along its extension direction, i.e., the front-rear direction.

[0424]

[0451] The first wall 521 and the second wall 522 are continuous with the third wall 523 .

[0425]

[0452] The third wall 523 forms another outer corner of the slot body 520. The third wall 523 is formed to extend in the width direction of the slot body 520 and supports the capacitor assembly 400 coupled to the slot body 520 at the other side. In the illustrated embodiment, the third wall 523 forms a front side wall of the slot body 520. In the embodiment, the third wall 523 is formed to extend in the left-right direction.

[0426]

[0453] The third wall 523 may be disposed on a surface such as the slot body 520. In other words, the third wall 523 is formed so as to support the capacitor assembly 400 from below, but not to restrain the capacitor assembly 400 in other directions. This is because the locking protrusion 540 is formed on the third wall 523 and supports one corner of the capacitor assembly 400 in the extension direction, which is the front side corner in the illustrated embodiment.

[0427]

[0454] The third wall 523 is coupled to the locking protrusion 540. The locking protrusion 540 is configured to support the one corner of the capacitor substrate 420 in the extension direction.

[0428]

[0455] Capacitor accommodating portion 524 is a space formed penetrating the interior of slot body 520. Capacitor accommodating portion 524 partially accommodates capacitor 410. In the illustrated embodiment, capacitor accommodating portion 524 is configured to partially accommodate a lower portion of a side surface of capacitor 410.

[0429]

[0456] The capacitor housing 524 may communicate with an opening formed in the capacitor substrate 420. The capacitor 410 may be housed in the opening and the capacitor housing 524, respectively.

[0430]

[0457] The capacitor housing 524 may be provided in any shape capable of partially housing the capacitor 410. In the illustrated embodiment, the capacitor housing 524 has a rectangular cross section whose extension length in the front-rear direction is longer than its extension length in the left-right direction, and is formed to penetrate in the up-down direction.

[0431]

[0458] There may be a plurality of capacitor housings 524. The plurality of capacitor housings 524 may be spaced apart from each other and may house a plurality of different capacitors 410, respectively.

[0432]

[0459] In the embodiment shown, a total of four capacitor housings 524 are provided, including a pair arranged biased toward the front side and another pair arranged biased toward the rear side.

[0433]

[0460] The shape, number, and arrangement of the capacitor receiving portions 524 may be changed according to the shape, number, and arrangement of the capacitors 410 provided.

[0434]

[0461] The capacitor support portion 530 is a portion where the slot member 500 is coupled to the capacitor assembly 400. The capacitor support portion 530 supports the capacitor substrate 420 of the capacitor assembly 400.

[0435]

[0462] The capacitor support part 530 may be made of a material having a certain elasticity. When the capacitor substrate 420 is inserted, the capacitor support part 530 may move outward in its width direction by a certain distance, be deformed, and store a restoring force. When the coupling of the capacitor substrate 420 is completed, the capacitor support part 530 may be restored to its original shape before deformation by the restoring force, and may support the capacitor substrate 420.

[0436]

[0463] In other words, the capacitor support 530 is snap-coupled to the capacitor substrate 420 and elastically supports the capacitor substrate 420 .

[0437]

[0464] In one embodiment, the capacitor support 530 may be made of a synthetic resin material such as PC-ABS.

[0438]

[0465] The capacitor support portions 530 may be formed at corners of the slot body 520. In the illustrated embodiment, the capacitor support portions 530 are formed at a pair of corners, i.e., a left corner and a right corner, in the longitudinal direction of the slot body 520. In other words, the capacitor support portions 530 are formed at each corner in the width direction of the slot body 520.

[0439]

[0466] There may be a plurality of capacitor supports 530. The plurality of capacitor supports 530 may be formed at the corners of the slot body 520, respectively.

[0440]

[0467] In the illustrated embodiment, the capacitor supports 530 formed at the left corners of the slot body 520 are formed as a pair and arranged side by side to face each other across the first wall 521. That is, the capacitor supports 530 formed at the left corners of the slot body 520 are arranged spaced apart from each other in the longitudinal direction of the slot body 520.

[0441]

[0468] In the illustrated embodiment, the capacitor supports 530 formed at the right corners of the slot body 520 are also formed as a pair and are arranged side by side facing each other across the second wall 522. That is, the capacitor supports 530 formed at the right corners of the slot body 520 are also arranged spaced apart from each other in the longitudinal direction of the slot body 520.

[0442]

[0469] Therefore, the capacitor assembly 400 coupled to the slot member 500, specifically, the capacitor substrate 420, may be supported at a plurality of positions by the capacitor support portion 530. As a result, the coupled state between the capacitor assembly 400 and the slot member 500 may be stably maintained.

[0443]

[0470] In the embodiment shown, the capacitor support 530 includes a support body 531 and a support protrusion 532 .

[0444]

[0471] The support body 531 is a portion where the capacitor support portion 530 is coupled to the slot body 520. The support body 531 is formed to extend from a corner of the slot body 520 in a direction toward the capacitor assembly 400, that is, upward in the illustrated embodiment. In other words, the support body 531 is formed to protrude in the same direction as the first wall 521 or the second wall 522.

[0445]

[0472] The support body 531 is formed to partially surround the capacitor substrate 420 from the outside. That is, the support body 531 formed at the left corner of the slot body 520 partially surrounds the left corner of the capacitor substrate 420, in other words, the third corner 423. Also, the support body 531 formed at the right corner of the slot body 520 partially surrounds the right corner of the capacitor substrate 420, that is, the fourth corner 424.

[0446]

[0473] The support body 531 is formed to extend a predetermined length in the direction in which the slot body 520 extends, that is, in the front-rear direction in the illustrated embodiment. In this case, the support body 531 may be shorter than the extension length of the first wall 521 or the second wall 522 in the same direction.

[0447]

[0474] A support protrusion 532 is formed to protrude inward from the support body 531 .

[0448]

[0475] The support protrusions 532 support the capacitor assembly 400, particularly the capacitor substrate 420, seated in the slot body 520. In one embodiment, the support protrusions 532 may support the capacitor substrate 420 by applying downward pressure thereto.

[0449]

[0476] The support protrusions 532 extend inward from the support body 531. In the illustrated embodiment, the support protrusions 532 of the capacitor support parts 530 located at the left corners of the slot body 520 extend toward the right side. Also, the support protrusions 532 of the capacitor support parts 530 located at the right corners of the slot body 520 extend toward the left side.

[0450]

[0477] The support protrusion 532 is disposed at a predetermined distance from one end, in the illustrated embodiment, the lower end, where the support body 531 is coupled to the slot body 520. In one embodiment, the distance between the support protrusion 532 and the one end may be greater than or equal to the thickness of the capacitor substrate 420.

[0451]

[0478] That is, the capacitor substrate 420 is supported at each corner in its extension direction, that is, in the illustrated embodiment, the third corner 423 on the left side and the fourth corner 424 on the right side, by the support protrusions 532 and one surface of the slot body 520. It will be understood that the one surface of the slot body 520 is the top surface facing the capacitor substrate 420.

[0452]

[0479] The support protrusion 532 may have any shape capable of supporting the capacitor substrate 420 by applying pressure to the one surface of the slot body 520. In the illustrated embodiment, the support protrusion 532 is formed such that the extension length in the front-rear direction is longer than the extension length in the up-down direction and has a thickness in the left-right direction.

[0453]

[0480] At this time, each corner in the upper and lower direction of the support protrusions 532 may be chamfered (tapered). This allows the capacitor substrate 420 to be easily inserted by pressing the support protrusions 532 outward. In addition, when the support protrusions 532 are moved outward by an external force, the capacitor substrate 420 may be easily removed from the slot member 500.

[0454]

[0481] That is, the capacitor assembly 400 can be snap-coupled to the slot member 500 by the support protrusions 532. In other words, the capacitor assembly 400 and the slot member 500 are elastically coupled.

[0455]

[0482] The locking protrusion 540 supports one side in the extension direction of the capacitor assembly 400 coupled to the slot member 500. The locking protrusion 540 allows the capacitor assembly 400 to be pulled out of the housing 100 together with the slot member 500.

[0456]

[0483] The locking protrusion 540 is coupled to the slot body 520. The locking protrusion 540 is formed to extend outward from one end of the slot body 520 in the extension direction. In the illustrated embodiment, the locking protrusion 540 is formed to extend forward from a third wall 523 formed at the front end of the slot body 520.

[0457]

[0484] A plurality of locking protrusions 540 may be provided. The plurality of locking protrusions 540 may be arranged spaced apart from each other in the width direction of the slot body 520. In the illustrated embodiment, two locking protrusions 540 are provided and arranged spaced apart from each other in the extension direction of the third wall 523, i.e., in the left-right direction.

[0458]

[0485] The space formed between the plurality of locking protrusions 540 communicates with the support space portion 452. The capacitor connector 430 is positioned in the space formed between the plurality of locking protrusions 540. When the capacitor assembly 400 and the slot member 500 are moved, the connector 220 can be accommodated in the space.

[0459]

[0486] The multiple locking protrusions 540 can support the one end of the capacitor substrate 420 at different positions. In the illustrated embodiment, the multiple locking protrusions 540 support the second corner 422 on the left and right sides, respectively. Therefore, when the slot member 500 is pulled out from the housing 100, the capacitor assembly 400 is supported at its front side corner (i.e., the second corner 422) by the multiple locking protrusions 540, and can be pulled out together with the slot member 500.

[0460]

[0487] In the embodiment shown, the locking projection 540 includes a first extension 541 , a second extension 542 , and a third extension 543 .

[0461]

[0488] The first extension portion 541 is a portion where the locking projection 540 is continuous with the slot body 520. The first extension portion 541 is formed to extend outward from the third wall 523 of the slot body 520, toward the front side in the illustrated embodiment.

[0462]

[0489] It is preferable that the first extension portion 541 extends sufficiently so that the capacitor substrate 420 can be completely accommodated on the upper surface of the slot body 520. In one embodiment, the distance between one end of the extension direction of the first extension portion 541, in the illustrated embodiment, the front end, and the grip portion 510 may be equal to or greater than the length of the capacitor substrate 420 in the front-rear direction.

[0463]

[0490] The first extension 541 is continuous with the second extension 542. The first extension 541 and the second extension 542 are continuous with each other at a predetermined angle. In one embodiment, the predetermined angle may be a right angle.

[0464]

[0491] The second extension portion 542 supports one end of the capacitor substrate 420 in the extension direction of the locking protrusion 540. The second extension portion 542 is continuous with the first extension portion 541 at a predetermined angle.

[0465]

[0492] The second extension portion 542 may extend by a length equal to or greater than the thickness of the capacitor substrate 420. Specifically, the extension portion 542 preferably extends such that the distance between a lower end of a third extension portion 543 formed on one side toward the slot body 520, in the illustrated embodiment, the rear side, and the upper surface of the slot body 520 is equal to or greater than the thickness of the capacitor substrate 420.

[0466]

[0493] A third extension portion 543 is formed on one surface of the second extension portion 542 facing the slot body 520, that is, on the rear side surface in the illustrated embodiment.

[0467]

[0494] The third extension portion 543 supports the capacitor substrate 420 seated on the slot body 520 at one side in the thickness direction, in the illustrated embodiment, at the upper side. The third extension portion 543 prevents the second corner 422 of the capacitor substrate 420 from arbitrarily detaching from the slot member 500.

[0468]

[0495] The third extension portion 543 extends from the one surface of the second extension portion 542, which in the illustrated embodiment is the front side surface, in a direction toward the slot body 520, i.e., toward the rear side. The third extension portion 543 extends a predetermined length from one end in the extension direction of the second extension portion 542, which in the illustrated embodiment is the upper end, toward the rear side and downward.

[0469]

[0496] The third extension portion 543 may have any shape capable of supporting from above the second corner 422 of the capacitor substrate 420 seated in the slot body 520. In the illustrated embodiment, the third extension portion 543 has an upper end portion continuous with an upper end portion of the second extension portion 542, and a lower end portion spaced a predetermined distance from the upper surface of the first extension portion 541.

[0470]

[0497] At this time, it is preferable that the distance between the lower end of the third extension 543 and the upper surface of the first extension 541 is greater than or equal to the thickness of the capacitor substrate 420 .

[0471]

[0498] 3. Description of the coupling process of the power electronic device 10 according to the embodiment of the present invention

[0499] In the power electronic device 10 according to the embodiment of the present invention described above, the capacitor assembly 400 may be modularized and coupled to the housing 100. In this case, the capacitor assembly 400 may be supported by the slot member 500, guided by the guide member 300, and inserted into the housing 100.

[0472]

[0500] At the same time, by inserting the capacitor assembly 400 into the housing 100 , the capacitor assembly 400 can also be coupled to the PCB assembly 200 and electrically connected to the PCB assembly 200 .

[0473]

[0501] No additional fasteners or tools are required in the process, making the installation and disassembly process easy.

[0474]

[0502] Furthermore, since the capacitor assemblies 400 are provided in a modularized form, the capacitor assemblies 400 can be operated and maintained independently. Therefore, even when the capacitor assemblies 400 are separated and maintained, it is not necessary to power off the power electronic device 10, and the convenience of the work can be improved.

[0475]

[0503] Hereinafter, a coupling process of the power electronic device 10 according to the embodiment of the present invention will be described in detail with reference to FIGS.

[0476]

[0504] In the illustrated embodiment, a process is shown in which the capacitor assembly 400 and the slot member 500 are coupled to the housing 100 and the PCB assembly 200. It will be understood that a process in which the capacitor assembly 400 and the slot member 500 are separated from the housing 100 and the PCB assembly 200 can be performed by performing the process in reverse according to the illustrated embodiment.

[0477]

[0505] 18 to 21, there is shown a process in which the capacitor assembly 400 and the slot member 500 are coupled to the PCB assembly 200 and electricity is applied between the capacitor assembly 400 and the PCB assembly 200. For ease of understanding and explanation, the housing 100 is omitted from the illustration.

[0478]

[0506] Prior to the above process, a process of coupling the capacitor assembly 400 and the slot member 500 may be performed. Through the coupling, the capacitor 410 may be partially accommodated in the capacitor accommodating portion 524, and each corner of the capacitor substrate 420 may be supported by different components of the slot member 500.

[0479]

[0507] Specifically, the first corner 421 of the capacitor substrate 420 may be supported by the gripping portion 510, and the second corner 422 may be supported by the locking protrusion 540. In addition, the third corner 423 may be supported by the first wall 521 and a capacitor support portion 530 positioned adjacent thereto, and the fourth corner 424 may be supported by the second wall 522 and a capacitor support portion 530 positioned adjacent thereto.

[0480]

[0508] At this time, the capacitor supporting part 530 is snap-coupled to the third corner 423 and the fourth corner 424 of the capacitor substrate 420 to elastically support the capacitor substrate 420. In addition, the locking protrusion 540 supports the second corner 422 of the capacitor substrate 420.

[0481]

[0509] The capacitor assembly 400 and the slot member 500 coupled thereto are moved toward the PCB assembly 200 to enter the insertion space S. In the embodiment shown, the capacitor assembly 400 and the slot member 500 coupled thereto are moved toward the rear side to be coupled with the PCB assembly 200.

[0482]

[0510] At this time, the corners of the capacitor assembly 400 and the slot member 500 coupled thereto are supported by the first guide member 300a and the second guide member 300b in the extension direction. The left and right corners of the capacitor assembly 400, i.e., the third and fourth corners 423, 424 and the left and right corners of the slot member 500, are inserted into the guide hollows 314 of the first and second guide members 300a, 300b, respectively.

[0483]

[0511] The capacitor assembly 400 and the slot member 500 coupled thereto are moved in the extension direction of the guide member 300, that is, rearward in the illustrated embodiment. At this time, the capacitor assembly 400 and the slot member 500 coupled thereto can be coupled to the guide member 300 while forming a predetermined play in its width direction, that is, in the vertical direction in the illustrated embodiment.

[0484]

[0512] Therefore, even if the capacitor assembly 400 and the slot member 500 coupled thereto form a certain error and are accommodated in the guide member 300, the capacitor assembly 400 and the slot member 500 coupled thereto can be guided and moved by the guide member 300.

[0485]

[0513] Meanwhile, when the capacitor assembly 400 and the slot member 500 coupled thereto are inserted into the guide member 300, the capacitor connector 430 may be arranged in a straight line with the connector 220, etc. Thus, when the capacitor assembly 400 and the slot member 500 coupled thereto are moved toward the connector 220, the capacitor connector 430 may be inserted into and coupled to the connector 220 and energized.

[0486]

[0514] 21, capacitor assembly 400 and slot member 500 coupled thereto are supported by having their upper and lower corners accommodated in first guide member 300a and second guide member 300b, respectively. At this time, capacitor connector 430 is inserted into connector 220, and electricity is passed between capacitor assembly 400 and PCB assembly 200.

[0487]

[0515] The connector 220 is accommodated in a support space 425 formed between a pair of support extensions 426 , that is, a pair of support spaces 425 defined by a capacitor connector 430 .

[0488]

[0516] Therefore, the capacitor assembly 400 and the PCB assembly 200 can be coupled and energized simply by moving the capacitor assembly 400 and the slot member 500 coupled thereto along the guide member 300. As described above, no separate fastening members or tools are required in this process.

[0489]

[0517] 22 to 24, there is shown a process in which the capacitor assembly 400 and the slot member 500 coupled thereto are coupled to the housing 100. For ease of understanding, the PCB assembly 200 and the guide member 300 are omitted from the illustration.

[0490]

[0518] It will be understood that the illustrated bonding process is performed simultaneously with the process in which the capacitor assembly 400 and associated slot member 500 described above are bonded to and moved with the PCB assembly 200 and guide member 300.

[0491]

[0519] 18 to 21 show a process in which the capacitor assembly 400 and the slot member 500 coupled thereto are coupled to the PCB assembly 200 and the guide member 300 accommodated inside the housing 100. As shown in FIG.

[0492]

[0520] 22 to 24 show a process in which capacitor assembly 400 and slot member 500 coupled thereto are coupled to housing 100. As shown in FIG.

[0493]

[0521] The capacitor assembly 400 and the slot member 500 coupled thereto are drawn into the housing 100 through the insertion opening 110. At this time, one end where the capacitor connector 430 coupled to the PCB assembly 200 is located, in the illustrated embodiment, the rear end, enters the accommodating space 104 through the insertion opening 110 first.

[0494]

[0522] At this time, the housing 100 is formed with the identification protrusion 125, and the slot member 500 is formed with the identification recess 514. This makes it easy to recognize that the capacitor assembly 400 and the slot member 500 should be inserted in a direction in which the identification protrusion 125 and the identification recess 514 are aligned. In the illustrated embodiment, the capacitor assembly 400 and the slot member 500 are pulled into the housing 100 so that the identification recess 514 is located on the left side.

[0495]

[0523] As the capacitor assembly 400 and the slot member 500 are pulled in, the insertion protrusion 513 comes into contact with the support frame 120. Depending on the shape of the insertion protrusion 513, i.e., the shape chamfered in the thickness direction, the insertion protrusion 513 is pressed inward by the support frame 120 and pulled into the accommodating space 104.

[0496]

[0524] At this time, the pressure projection 512 is also pressed inward together with the insertion projection 513 and is drawn into the accommodation space 104 .

[0497]

[0525] When the retraction of the capacitor assembly 400 and the slot member 500 is completed, the insertion protrusion 513 is moved to the rear side of the support frame 120. As a result, the external force applied to the insertion protrusion 513 by the support frame 120 is released.

[0498]

[0526] In this state, the insertion protrusion 513 and the pressure protrusion 512 coupled thereto are restored to their original shapes and moved in the outward direction, whereby the insertion protrusion 513 is supported by the rear side of the support frame 120. This limits the movement of the capacitor assembly 400 and the slot member 500 in the direction to be pulled out of the housing 100, that is, in the illustrated embodiment, to the forward side.

[0499]

[0527] In this state, the pressure projections 512 are housed in the gripping spaces 130. The gripping spaces 130 are formed to have a larger volume than the pressure projections 512. In particular, the gripping spaces 130 extend in a direction toward the inside of the pressure projections 512, that is, in the illustrated embodiment, in the vertical direction by a length greater than that of the pressure projections 512. Therefore, an operator can insert a finger or the like into the gripping space 130 to apply pressure to the pressure projections 512 inward, thereby moving the insertion projections 513 inward.

[0500]

[0528] In addition, in this state, the outer surface (i.e., the front side) of the gripping portion 510 and the outer surface (i.e., the front side) of the housing 100 may be located on the same plane, so that the slot member 500 and the capacitor assembly 400 coupled thereto do not protrude outward.

[0501]

[0529] Meanwhile, in order to separate the slot member 500 and the capacitor assembly 400 coupled thereto from the housing 100, the restraint state of the insertion protrusion 513 by the support frame 120 must be released. For this reason, as shown in Fig. 17, it will be understood that when the pressure protrusion 512 is pressed inward, the insertion protrusion 513 is also moved inward, and the restraint state can be released.

[0502]

[0530] Although an embodiment of the present invention has been described, the concept of the present invention is not limited to the embodiment presented in this specification, and a person skilled in the art who understands the concept of the present invention can easily propose other embodiments by adding, changing, deleting, adding, etc., components within the scope of the same concept, which can also be said to be within the scope of the concept of the present invention.
