Description

Technical Field

[0001] The present invention relates to a coupling member and a power electronic device including the same, and more particularly to a coupling member having a structure capable of easily coupling a power electronic device and a terminal member that communicates with and conducts electricity to the power electronic device, and a power electronic device including the coupling member. Background Art

[0002] One type of power electronic equipment, namely PLC (Programmable Logic Circuit), is a programmable logic control device widely used in automatic control of equipment and engineering control for performing discontinuous operations. PLC is equipped with a PCB for processing control signals and capacitors for supplying power to the PCB.

[0003] Traditionally, PLCs are configured as a single device, limited to providing a set power capacity. However, recently, PLCs have been configured as modules, and the power capacity configuration can be changed according to the number of power electronic devices configured. To this end, multiple PLCs are combined into a device called a base.

[0004] As PLCs are configured in modular form, not only can the power capacity be changed, but also only the PLC with a problem can be separated from multiple PLCs, repaired, and then reconnected to the base. As a result, the popularity of modular PLCs is increasing.

[0005] However, as the PLC is detachably coupled to the base, various problems arise, unlike the previous case where the PLC was fixedly coupled to the base.

[0006] First, there is a risk that the PLC and the base are damaged or arbitrarily separated due to incomplete bonding of the PLC and the base. In addition, there is a concern that the part of the PLC and the base that is bonded together may be damaged due to the inexperience of the operator.

[0007] On the other hand, when a PLC configured as a module needs to be repaired, the cover of the PLC must be removed in order to replace the problematic component.

[0008] Generally, considering that the cover of a PLC is formed in one piece to maintain rigidity, when the cover is separated and reassembled to repair the component, it is difficult to maintain the same rigidity as before the repair. As a result, maintenance requires excessive time and cost, and there is a concern that the convenience of operation and user satisfaction will be reduced.

[0009] In particular, when the PLC cover is configured as an integrated type, the vibration generated when the PLC and the base are working or the impact generated when the PLC and the base are connected and separated may cause excessive stress to be generated at the connection point between the PLC and the base. In this case, the possibility of damage to the connection point also increases. In the case where the PLC cover is formed as an integrated type, in order to repair the part, the entire cover must be replaced.

[0010] In addition, when the structure of the PLC and the cover are configured as an integrated structure, the PCB and other structures must be separated in order to replace the cover. As a result, there is a concern that the structure of the PLC may be damaged and the operating reliability may be reduced during reassembly.

[0011] Korean Patent No. 10-1342513 discloses an assembly base of an electronic watt-hour meter, in which an input terminal block and an output terminal block can be assembled and disassembled to form a terminal base, thereby changing the power capacity of the watt-hour meter.

[0012] However, the assembly base of the electronic electric energy meter disclosed in the prior art document only provides a solution for combining the input / output side terminal block in an assembly-detachable manner to make the power capacity variable. That is, the prior art document cannot provide a solution for preventing the terminal block or the assembly base from being damaged due to the impact generated when the input / output side terminal block and the assembly base are combined and separated.

[0013] Korean Patent Document No. 10-1011034 discloses a modular measuring instrument integrated system in which the housing of a measuring circuit is modularized. Specifically, the modular measuring instrument integrated system in which the housing of a measuring circuit is modularized and detachably mounted on a base portion so that the number of measuring instrument modules can be changed is disclosed.

[0014] However, the modular measuring instrument integrated system disclosed in the prior art document, which modularizes the housing of the measuring circuit, requires a separate guide member for supporting the combined measuring instrument module. In addition, the base module in the prior art document is configured to support the measuring instrument module from the bottom, which has the limitation of being difficult to apply in another direction, such as the front-to-back direction or the left-to-right direction.

[0015] Furthermore, the prior art documents fail to provide a solution for maintaining the combined state of the PLC and the base by reducing the vibration generated when the PLC is working.

[0046] Effects of the Invention

[0047] According to the above configuration, in the coupling member and the power electronic device including the coupling member according to the embodiment of the present invention, the power electronic device and the connection terminal member can be coupled together by a single member.

[0048] A coupling member is provided in the power electronic device. The coupling member is detachably coupled to a coupling member assembly and disassembly portion provided on the power electronic device. The coupling member includes a coupling arm extending toward the power electronic device. The coupling member assembly and disassembly portion includes a coupling opening portion, the coupling opening portion is formed through the upper side surface of the cover body, and the coupling arm can be coupled to the coupling opening portion through the coupling opening portion in a manner that allows it to be drawn out.

[0049] The coupling arm includes: a coupling extension portion extending toward the coupling opening portion and penetrating and coupling with the coupling opening portion; and a coupling protrusion protruding outward from an end portion of the coupling extension portion and hook-coupled with the coupling opening portion.

[0050] Therefore, if the coupling member and the coupling member attaching and detaching portion are coupled, the coupling member and the cover of the power electronic device can be detachably coupled.

[0051] On the other hand, the coupling member includes a coupling body forming a main body thereof and a coupling protrusion continuous with the coupling body. The coupling protrusion protrudes upward.

[0052] The connection terminal member to which the coupling member is detachably coupled includes a supporting member. The supporting member includes a first extending arm extending toward the front side and a second extending arm extending from an end of the first extending arm toward the coupling member.

[0053] If the power electronic device coupled to the coupling member moves toward the terminal member, the second extension arm is pressed by the coupling protrusion and deforms upward and stores a restoring force. If the coupling protrusion passes the second extension arm, the second extension arm is restored to its original shape by the restoring force and is hooked with the coupling protrusion.

[0054] Thereby, the power electronic device and the connection terminal member can be detachably coupled via a single coupling member.

[0055] Furthermore, according to the above configuration, the coupling member and the power electronic device including the coupling member according to the embodiment of the present invention can prevent damage to the power electronic device.

[0056] As described above, the power electronic device and the terminal member are detachably connected via the connecting member. Therefore, in the event of damage to the connecting member, only the connecting member can be removed for maintenance. That is, there is no need to disassemble the structure of the power electronic device for maintenance of the connecting member.

[0057] Therefore, since maintenance can be performed by simply separating the coupling member, damage to the configuration of the power electronic equipment can be prevented.

[0058] Furthermore, according to the above configuration, the coupling member and the power electronic device including the coupling member according to the embodiment of the present invention can prevent damage to the power electronic device caused by vibration.

[0059] The coupling member includes a support arm. The support arm is located at the lowest side of the coupling member. In other words, when the coupling member is coupled to the power electronic device, the support arm is located at the lowest side of the portion exposed to the outside. Therefore, the support arm contacts the upper side of the cover body and elastically supports other components of the coupling member.

[0060] When the power electronic device or the terminal member vibrates during operation, the support arm is pressurized to deform and store elastic force, so that the vibration of the power electronic device is buffered and the shock caused by the vibration transmitted to the components of the power electronic device can be minimized.

[0061] Therefore, it is possible to prevent damage to the components of the power electronic equipment due to vibration.

[0062] Furthermore, according to the above configuration, the coupling member according to the embodiment of the present invention and the power electronic device including the coupling member can be prevented from moving arbitrarily.

[0063] The coupling member includes a guide portion. The guide portion is formed through the left side and the right side of the coupling body, and includes a plurality of guide grooves extending in the up-down direction. A plurality of guide plates provided on the coupling member assembly and disassembly portion are movably accommodated in the plurality of guide grooves. By combining the guide plates and the guide grooves, the power electronic device can be prevented from moving in any way in the front-back direction.

[0064] In addition, the guide portion includes a plate receiving groove which is a space recessed inside the combined body. The plate receiving groove is provided with guide ribs extending in the front-to-back direction and the up-down direction. A rib receiving portion is arranged in the combined component assembly and disassembly portion, and the rib receiving portion is a space formed between a plurality of guide plates separated from each other. The guide rib is received in the rib receiving portion and is constrained in the left-right direction by the plurality of guide plates. By combining the guide rib and the rib receiving portion, arbitrary movement of the power electronic device in the left-right direction can be prevented.

[0065] Thus, any movement of the power electronics can be prevented.

[0066] Furthermore, according to the above configuration, the coupling member and the power electronic device including the coupling member according to the embodiment of the present invention can stably maintain the coupling state between the power electronic device and the connection terminal member.

[0067] According to the above configuration, the coupling member is hook-coupled with the power electronic device and the terminal member, respectively, and the coupling member will not be separated from the power electronic device or the terminal member unless an external force in a predetermined direction is applied.

[0068] In addition, the coupling member is provided with a support arm. The support arm is configured to buffer vibration in the vertical direction applied to the power electronic device. Thus, the power electronic device and the coupling state of the terminal member and the coupling member can be stably maintained.

[0069] Furthermore, the connecting member is provided with a guide part, and the connecting member attaching and detaching part is connected with the member guide part. By connecting the guide part and the member guide part, the power electronic device is prevented from moving in any direction in the front-back direction and the left-right direction.

[0070] Therefore, the coupling member can be stably coupled to the power electronic device and the terminal member, can buffer vibration in the up-down direction, and can prevent any movement in the front-back direction and the left-right direction. As a result, the coupling state of the coupling member, the power electronic device and the terminal member can be stably maintained.

[0071] The effects of the present invention are not limited to the above-described effects, and it is understood that the effects include all effects that can be inferred from the detailed description of the present invention or the configuration of the invention described in the claims.

[0128] The base groove 131 may be formed in plural. The plural base grooves 131 may be arranged to be spaced apart from each other along the extending direction of the support base 130. In addition, the plural base grooves 131 may be arranged to correspond to the positions of the groove member 120 and the support member 140.

That is, the number of base grooves 131 can be set to be less than the number of power electronic devices 20, and the plurality of base grooves 131 can respectively support the plurality of power electronic devices 20.

[0133] The support base 130 faces the support member 140 across the trough member 120 .

[0134] The support member 140 supports the power electronic device 20 coupled to the connection terminal member 10 on the other side in the height direction of the power electronic device 20, on the upper side in the illustrated embodiment. The support member 140 is coupled to the coupling member 400 coupled to the coupling member attachment and detachment portion 300 of the power electronic device 20 to partially support the rear side of the upper portion of the power electronic device 20.

[0135] The support member 140 is located at the other end in the height direction of the terminal body 100, that is, the upper end in the illustrated embodiment. The support member 140 is formed to protrude toward the direction in which the power electronic device 20 is separated, that is, the front side in the illustrated embodiment.

[0136] The support member 140 is detachably coupled to the coupling member 400, which is provided in the power electronic device 20. In one embodiment, the support member 140 may be hook-fitted with the coupling member 400. Therefore, unless a prescribed force is applied in a predetermined direction, the coupling state of the support member 140 and the coupling member 400 may be maintained.

[0137] The support member 140 can be arranged at any position that can be coupled to the coupling member 400 of the power electronic device 20. In the illustrated embodiment, the support member 140 is arranged to overlap the groove member 120 and the base groove 131 along the height direction of the terminal body 100, that is, the vertical direction.

[0138] A plurality of support members 140 may be provided. The plurality of support members 140 may be spaced apart from each other along the length direction of the terminal body 100. In the illustrated embodiment, ten support members 140 are provided and spaced apart from each other along the left-right direction.

[0139] In the illustrated embodiment, the support member 140 includes a first extending arm 141 , a second extending arm 142 , a third extending arm 143 , and a member receiving portion 144 .

[0140] The first extension arm 141 forms a part of the support member 140. The first extension arm 141 extends outward from the upper end of the terminal body 100, that is, the front side in the illustrated embodiment. The first extension arm 141 forms the upper part of the support member 140.

[0141] The first extension arm 141 partially covers the coupling member 400 and the coupling member attaching and detaching portion 300 coupled to the coupling member 400 at the upper side. As described later, the first extension arm 141 covers a portion of the second coupling body 412 of the coupling member 400 at the upper side.

[0142] The end of the first extension arm 141 in the extension direction is connected to one end of the terminal body 100, that is, the rear end in the illustrated embodiment is continuous with the upper end of the terminal body 100. The other end of the first extension arm 141 in the extension direction, that is, the front end in the illustrated embodiment, is continuous with the second extension arm 142.

[0143] The second extension arm 142 is detachably coupled to a coupling protrusion 416 formed at an end of the second coupling body 412. In one embodiment, the second extension arm 142 may be hook-coupled to the coupling protrusion 416.

[0144] At the same time, the second extension arm 142 presses the upper side of the second coupling body 412. Thus, the coupling member 400 and the supporting member 140 can be detachably coupled and can stably maintain the coupled state.

[0145] The second extension arm 142 is continuous with the first extension arm 141. The second extension arm 142 is continuous with the other end portion of the first extension arm 141, that is, the front end portion in the illustrated embodiment.

[0146] The second extension arm 142 may be divided into a plurality of parts. In the illustrated embodiment, the second extension arm 142 includes a first extension surface 142a, a second extension surface 142b, a third extension surface 142c, a fourth extension surface 142d, and a fifth extension surface 142e.

[0147] The first extension surface 142a is a portion of the second extension arm 142 that is continuous with the first extension arm 141. The first extension surface 142a extends in a manner that forms a predetermined angle with the first extension arm 141. In the illustrated embodiment, the first extension surface 142a forms an obtuse angle with the first extension arm 141 and extends in the direction of the lower side in the front. In other words, the first extension surface 142a extends obliquely toward the lower side in the front and the upper side in the rear.

[0148] The second extension surface 142b is continuous with the first extension surface 142a at a predetermined angle. In the illustrated embodiment, the second extension surface 142b forms an obtuse angle with the first extension surface 142a and extends toward the direction of the coupling member 400, that is, toward the lower side. In other words, the second extension surface 142b extends obliquely in the up-down direction.

[0149] The third extension surface 142c is continuous with the second extension surface 142b in a manner forming a predetermined angle. In the illustrated embodiment, the third extension surface 142c forms an obtuse angle with the second extension surface 142b and extends toward the direction of the coupling member 400, that is, toward the rear lower side. In other words, the third extension surface 142c extends obliquely toward the upper side in the front and the lower side in the rear.

[0150] If the power electronic device 20 moves toward the terminal member 10, the third extension surface 142c contacts the coupling protrusion 416 of the coupling member 400. At this time, the second support surface 416b of the coupling protrusion 416 extends obliquely corresponding to the third extension surface 142c. Therefore, the coupling member 400 can be easily inserted and coupled to the support member 140.

[0151] The fourth extension surface 142d is continuous with the third extension surface 142c in a manner that forms a predetermined angle. In the illustrated embodiment, the fourth extension surface 142d forms an obtuse angle with the third extension surface 142c and extends in the direction of the terminal body 100, that is, in the direction of the rear side in the illustrated embodiment. In other words, the fourth extension surface 142d extends obliquely in the front-rear direction.

[0152] When the coupling member 400 is coupled to the supporting member 140 , the upper side surface of the second coupling body 412 of the coupling body 410 may contact the fourth extension surface 142 d . Thus, the coupling member 400 coupled to the terminal member 10 can be stably maintained.

[0153] The fifth extension surface 142e is continuous with the fourth extension surface 142d in a manner of forming a predetermined angle. In the illustrated embodiment, the fifth extension surface 142e forms an obtuse angle with the fourth extension surface 142d and extends toward the first extension arm 141, that is, toward the upper rear side. In other words, the fifth extension surface 142e extends obliquely toward the lower front side and the upper rear side.

[0154] If the coupling member 400 is coupled to the supporting member 140, the fifth extension surface 142e contacts the coupling protrusion 416 of the coupling body 410. At this time, the first support surface 416a of the coupling protrusion 416 may extend in a manner inclined corresponding to the fifth extension surface 142e. Therefore, the coupling protrusion 416 is stably supported by the fifth extension surface 142e, so that the coupling state of the coupling member 400 coupled to the terminal member 10 can be stably maintained.

[0155] The third extending arm 143 reinforces the rigidity of the first extending arm 141. In addition, the third extending arm 143 limits the length by which the coupling member 400 is inserted into the supporting member 140.

[0156] The third extension arm 143 is continuous with the first extension arm 141 so as to form a predetermined angle. In the illustrated embodiment, the third extension arm 143 is formed to extend perpendicularly to the first extension arm 141 in the up-down direction.

[0157] The third extension arm 143 is spaced apart from the second extension arm 142. In the illustrated embodiment, the third extension arm 143 is located behind the first extension arm 141 and adjacent to the terminal body 100.

[0158] A space surrounded by the first extending arm 141 , the second extending arm 142 , and the third extending arm 143 is defined as a component receiving portion 144 .

[0159] The component accommodating portion 144 is a space for accommodating the coupling component 400. The component accommodating portion 144 is defined by being partially surrounded by the first extension arm 141, the second extension arm 142, and the third extension arm 143. The component accommodating portion 144 is formed open toward one side of the power electronic device 20, that is, the front side in the illustrated embodiment. The coupling component 400 can be inserted into the accommodating portion 144 or drawn out from the component accommodating portion 144 through the one side.

[0160] The member accommodating portion 144 may be formed to have a height longer than the height of the coupling member 400, that is, the length in the up-down direction. In addition, the member accommodating portion 144 may be formed to have a length longer than the length of the coupling member 400, that is, the length in the front-back direction. Thus, in the case where the power electronic device 20 coupled to the terminal member 10 vibrates, the impact caused by the vibration can be buffered by the coupling member 400.

[0161] The device housing 150 is a space that houses a portion of the housing 200 of the power electronic device 20. In the illustrated embodiment, the device housing 150 houses left and right portions of the coupling member attachment and detachment portion 300 formed on the upper rear side of the second housing 220.

[0162] The device receiving portion 150 may be formed to correspond to the shape of the remaining portion of the rear upper portion of the second housing 220 excluding the coupling member attaching and detaching portion 300. In the illustrated embodiment, the device receiving portion 150 is formed to extend in the left-right direction like the terminal body 100.

[0163] The side of the device accommodating portion 150 facing the power electronic device 20, that is, the front side in the illustrated embodiment, is open. The second cover 220 can be inserted into the device accommodating portion 150 or drawn out from the device accommodating portion 150 through the side.

[0164] The other side of the device housing 150 is formed open in each side in the height direction, that is, the upper side and the lower side in the illustrated embodiment. When the terminal member 10 or the power electronic device 20 coupled thereto vibrates in the up-down direction, the power electronic device 20 vibrates through the sides of the device housing 150, and the impact can be mitigated.

[0165] The device accommodating parts 150 may be formed in plurality. The plurality of device accommodating parts 150 may be arranged spaced apart from each other. In the illustrated embodiment, there are ten device accommodating parts 150, which are arranged spaced apart from each other along the extending direction of the terminal body 100, that is, the left-right direction.

[0166] The plurality of support members 140 are respectively located between the plurality of device receiving portions 150. In other words, along the length direction of the terminal body 100, the plurality of support members 140 and the plurality of device receiving portions 150 are alternately arranged with each other.

[0167] A fastening hole 160 is formed inside the device receiving portion 150 .

[0168] The fastening hole 160 is a space for inserting the fastening member 260 of the cover 200. The fastening hole 160 is formed concavely on one side of the terminal body 100 surrounding the device receiving portion 150, that is, the front side in the illustrated embodiment.

[0169] The fastening hole 160 may be arranged corresponding to the position of the fastening member 260. In the illustrated embodiment, the fastening hole 160 is arranged to be biased to the right side inside the device receiving portion 150.

[0170] The fastening hole 160 may be formed in any form into which the fastening member 260 can be inserted and coupled. In an embodiment where the fastening member 260 is configured as a threaded member, the fastening hole 160 may be threaded on its inner circumferential surface.

[0171] By combining the fastening hole 160 and the fastening member 260, the upper part of the power electronic device 20 can be combined with the terminal member 10 through the plurality of members, namely the coupling member 400 and the fastening member 260. Thus, the combined state of the terminal member 10 and the power electronic device 20 can be stably maintained.

[0172] A plurality of fastening holes 160 may be formed. The plurality of fastening holes 160 may be disposed in each of the plurality of device receiving portions 150 . In the illustrated embodiment, ten fastening holes 160 are formed, and may be disposed in each of the ten device receiving portions 150 .

[0212] The coupling member attaching and detaching part 300 is a part where the coupling member 400 is coupled to the cover 200, specifically, the second cover 220. The coupling member attaching and detaching part 300 is formed on the one side of the second cover 220, that is, the upper rear side in the illustrated embodiment.

[0213] The coupling member attachment and detachment part 300 is partially surrounded by the second frame 221 and the top surface 222. In the illustrated embodiment, the front side, the left side, and the right side of each side of the coupling member attachment and detachment part 300 are surrounded by the second frame 221, and the lower side is surrounded by the top surface 222. The remaining side of each side of the coupling member attachment and detachment part 300, that is, the upper side and the rear side in the illustrated embodiment, are open.

[0214] The coupling member 400 can be coupled to or separated from the coupling member attachment and detachment portion 300 through the upper side. In addition, the power electronic device 20 can be coupled to or separated from the terminal member 10 through the rear side. In one embodiment, the coupling member attachment and detachment portion 300 can be formed integrally with the second cover 220.

[0215] In the illustrated embodiment, the coupling component mounting and disassembling portion 300 includes a coupling component accommodating portion 310 , a coupling opening portion 320 , and a component guiding portion 330 .

[0216] The coupling member accommodating portion 310 is a space for accommodating the coupling member 400. In addition, the coupling member accommodating portion 310 accommodates other components of the coupling member attaching and detaching portion 300. The coupling member accommodating portion 310 is defined by being partially surrounded by the second frame 221 and the top surface 222.

[0217] The coupling member accommodating portion 310 may be divided into a plurality of portions by the member guide portion 330. In the illustrated embodiment, the coupling member accommodating portion 310 includes a first coupling member accommodating portion 311 formed on the front side and a second coupling member accommodating portion 312 formed on the rear side.

[0218] The first coupling member receiving portion 311 receives a portion of the first coupling body 411 of the coupling member 400. The first coupling member receiving portion 311 is defined by being surrounded by the second frame 221, the top surface 222, and the guide plates 331, 332. The upper side of the first coupling member receiving portion 311 is open.

[0219] The first coupling member receiving portion 311 communicates with a space formed inside the second housing 220. Specifically, the first coupling member receiving portion 311 communicates with the space through a first coupling opening 321 formed through a portion of the top surface 222 surrounding the first coupling member receiving portion 311.

[0220] The second coupling member accommodating portion 312 accommodates another portion of the first coupling body 411 of the coupling member 400, the second coupling body 412, and the support arm 440. The second coupling member accommodating portion 312 is defined by being surrounded by the second frame 221, the top surface 222, and the guide plates 331, 332. The upper side and the rear side of the second coupling member accommodating portion 312 are open.

[0221] The second coupling member receiving portion 312 communicates with a space formed inside the second housing 220. Specifically, the second coupling member receiving portion 312 communicates with the space through a second coupling opening 322 formed through another portion of the top surface 222 surrounding the second coupling member receiving portion 312.

[0222] The second coupling member accommodating portion 312 may be formed to have a relatively larger volume than the first coupling member accommodating portion 311. As described later, this is because the volumes of the other portion of the first coupling body 411 accommodated in the second coupling member accommodating portion 312, the second coupling body 412, and the support arm 440 are larger than the volume of the portion of the first coupling body 411 accommodated in the first coupling member accommodating portion 311.

[0223] The connecting opening 320 is formed through the top surface 222 to connect the connecting member receiving portion 310 and the inner space of the second cover 220. The connecting arm 420 of the connecting member 400 can pass through the opening 320 and be partially received in the inner space of the second cover 220.

[0224] The plurality of coupling openings 320 may be formed. The plurality of coupling openings 320 may be respectively formed in the plurality of coupling member accommodating portions 310. In the illustrated embodiment, the coupling openings 320 include a first coupling opening 321 formed in the first coupling member accommodating portion 311 and a second coupling opening 322 formed in the second coupling member accommodating portion 312.

[0225] The first coupling arm 421 is connected to the first coupling opening 321 in a manner that allows it to be drawn out. The second coupling arm 422 is connected to the second coupling opening 322 in a manner that allows it to be drawn out. Through the connection, the coupling arm 420 and the second cover body 220 can be hooked.

[0226] In the illustrated embodiment, the first and second coupling openings 321 and 322 are formed to have quadrilateral cross-sections. The shapes of the first and second coupling openings 321 and 322 may be changed according to the shapes of the first and second coupling arms 421 and 422 .

[0227] The member guide portion 330 guides the coupling member 400 so that the coupling member 400 is coupled to the coupling member attaching and detaching portion 300 in a predetermined direction and position.

[0228] The component guide portion 330 is located in the combined component accommodating portion 310. The component guide portion 330 divides the combined component accommodating portion 310 into a plurality of parts. In the illustrated embodiment, the component guide portion 330 is located at a position biased toward the front side of the combined component accommodating portion 310, and divides the combined component accommodating portion 310 into a first combined component accommodating portion 311 and a second combined component accommodating portion 312.

[0229] The component guide 330 and the coupling member 400 may be coupled in a form in which one of the two is inserted into the other in a movable manner. In this case, the component guide 330 and the coupling member 400 may be inserted and coupled in a movably manner at a plurality of positions.

[0230] In the illustrated embodiment, the member guide portion 330 includes a first guide plate 331 , a second guide plate 332 , and a rib accommodation portion 333 .

[0231] The first guide plate 331 and the second guide plate 332 are formed to protrude from the top surface 222. In the illustrated embodiment, the first guide plate 331 and the second guide plate 332 are formed to protrude toward the upper side.

[0232] The first guide plate 331 is inserted into the first guide groove 431a coupled to the coupling member 400. The first guide plate 331 extends along the extension direction of the first guide groove 431a, that is, the up-down direction in the illustrated embodiment. The first guide plate 331 is inserted into the first guide groove 431a in a movable manner to guide the lifting of the coupling member 400.

[0233] The second guide plate 332 is inserted into the second guide groove 431b coupled to the coupling member 400. The second guide plate 332 extends along the extension direction of the second guide groove 431b, that is, the up-down direction in the illustrated embodiment. The second guide plate 332 is inserted into the second guide groove 431b in a movable manner to guide the lifting and lowering of the coupling member 400.

[0234] The first guide plate 331 and the second guide plate 332 extend along the width direction of the second cover body 220, that is, the left-right direction in the illustrated embodiment. At this time, the extension length of each of the first guide plate 331 and the second guide plate 332 can be formed to be less than half of the length of the width direction of the coupling member accommodating portion 310.

[0235] Thus, the first guide plate 331 and the second guide plate 332 form a predetermined space between each other and are arranged side by side. In the illustrated embodiment, the first guide plate 331 is located at a position biased to the left, and the second guide plate 332 is located at a position biased to the right. Therefore, the coupling member 400 can be raised and lowered in a manner that both the left and right sides thereof are guided, thereby coupling with the coupling member assembly and disassembly portion 300 or separating from the coupling member assembly and disassembly portion 300.

[0236] The prescribed space formed between the first guide plate 331 and the second guide plate 332 is defined as a rib accommodation portion 333 .

[0237] The rib accommodation part 333 is a space for accommodating the guide rib 432 of the coupling member 400. The guide rib 432 may be inserted into the rib accommodation part 333 in a manner that it can be drawn out.

[0238] The rib receiving portion 333 is located between the first guide plate 331 and the second guide plate 332 . The left and right sides of the guide rib 432 received in the rib receiving portion 333 may be restrained by the first guide plate 331 and the second guide plate 332 .

[0239] Therefore, the vertical movement of the coupling member 400 coupled to the coupling member attaching and detaching portion 300 is permitted, while the front-rear or left-right movement is restricted. Thus, the coupled state of the coupling member 400 and the coupling member attaching and detaching portion 300 can be stably maintained.

[0240] It is understood that the positions and shapes of the first guide plate 331 , the second guide plate 332 , and the rib accommodating portion 333 may be changed according to the position and shape of the guide portion 430 of the coupling member 400 .

[0241] 4. Description of the Combination Component 400 of the Embodiment of the Present Invention

[0242] Refer again Figure 2 , the power electronic device 20 according to the embodiment of the present invention includes a coupling member 400 .

[0243] The coupling member 400 is detachably coupled to the coupling member attachment and detachment portion 300 and the connection terminal member 10. In other words, the coupling member 400 detachably couples the power electronic device 20 and the connection terminal member 10.

[0244] In this specification, the description is given on the premise that the coupling member 400 is a component of the power electronic device 20. Alternatively, the coupling member 400 may be provided separately from the power electronic device 20.

[0245] In the illustrated embodiment, the combining member 400 is configured as a single one. As an alternative, the combining member 400 is provided in plural, and can be detachably combined with the combining member assembly and disassembly portion 300 and the terminal member 10 at plural positions. It can be understood that in the embodiment, the combining member assembly and disassembly portion 300 is also configured in plural.

[0246] In one embodiment, the coupling member 400 can be hook-coupled with the coupling member attaching and detaching part 300 and the supporting member 140. Therefore, the coupling member 400 can be easily coupled with the coupling member attaching and detaching part 300 and the supporting member 140, and the coupled state can be kept stable.

[0247] In addition, the coupling member 400 of the embodiment of the present invention can buffer the vertical vibration of the power electronic device 20 by its own structure without separately providing an elastic member. Therefore, the manufacturing cost can be saved, the manufacturing efficiency can be improved, and the maintenance can be easily performed.

[0248] Each component of the coupling member 400 described below can be formed as one body, thereby reducing the number of steps for separately manufacturing each component and coupling them together, and making it possible to firmly maintain the coupling between each component.

[0249] In one embodiment, in each of the structures of the coupling member 400 described below, the coupling arm 420 may be formed of a PC GF10% (Polycarbonate Glass Fiber 10%) material. In addition, other structures of the coupling member 400 may be formed of a PC-ABS (Polycarbonate / Acrylonitrile Butadiene Styrene) material.

[0250] In the described embodiment, the strength and tension of the coupling arm 420 may be higher than other components of the coupling member 400 .

[0251] exist Figures 9 to 15 In the illustrated embodiment, the coupling member 400 includes a coupling body 410 , a coupling arm 420 , a guide portion 430 , and a support arm 440 .

[0252] The coupling body 410 forms the main body of the coupling member 400. The coupling body 410 is a portion of the coupling member 400 that is accommodated in the coupling member attachment and detachment section 300. The coupling body 410 is continuous with a portion of the coupling member 400. In addition, other components of the coupling member 400 are formed on the coupling body 410.

[0253] In the illustrated embodiment, the combining body 410 includes a first combining body 411 , a second combining body 412 , a pressurizing protrusion 413 , a pressurizing groove 414 , a board receiving groove 415 , and a combining protrusion 416 .

[0254] The first coupling body 411 forms a portion of the coupling body 410, ie, the front side in the illustrated embodiment. The first coupling body 411 is partially accommodated in the first coupling member accommodation portion 311 and the second coupling member accommodation portion 312, respectively.

[0255] The first connecting body 411 is formed to extend along the direction in which the connecting member 400 is connected to or separated from the connecting member attaching and detaching portion 300 , that is, in the up-down direction in the illustrated embodiment.

[0256] The first coupling body 411 may be in any shape that can be accommodated in the coupling member accommodation portion 310 and coupled to the guide portion 330. In the illustrated embodiment, the first coupling body 411 is in a polygonal column shape having a height in the vertical direction and a width in the horizontal direction.

[0257] The first combination body 411 can be divided into a plurality of parts. In the illustrated embodiment, the first combination body 411 includes a first part forming a front part and accommodated in the first combination member accommodation portion 311 and a second part forming a rear part and accommodated in the second combination member accommodation portion 312.

[0258] The guide groove 431 of the guide portion 430 is disposed between the first portion and the second portion. In other words, the first coupling body 411 is divided into the first portion and the second portion by the guide groove 431 disposed therein.

[0259] Therefore, the first portion and the second portion are arranged to face each other via the guide plates 331 , 332 inserted into the guide groove 431 .

[0260] One side of the first part of the first combining body 411, i.e., the lower side in the illustrated embodiment, is continuous with the first combining arm 421 of the combining arm 420. The other side of the first combining body 411, i.e., the upper side in the illustrated embodiment, is continuous with the pressurizing protrusion 413. The other side of the second part of the first combining body 411, i.e., the rear side in the illustrated embodiment, is continuous with the second combining body 412.

[0261] Furthermore, the other side of the second portion of the first combining body 411 , ie, the rear side in the illustrated embodiment, is continuous with the supporting arm 440 .

[0262] The second coupling body 412 forms another portion of the coupling body 410 , ie, the rear side in the illustrated embodiment. The second coupling body 412 is received in the second coupling member receiving portion 312 .

[0263] The second coupling body 412 is formed to extend along a direction in which the coupling member 400 is coupled to or separated from the supporting member 140 , that is, a front-to-rear direction in the illustrated embodiment.

[0264] One end of the second connecting body 412 in the extending direction, which faces the first connecting body 411, i.e., the front end in the illustrated embodiment, is continuous with the first connecting body 411. The other end of the second connecting body 412 in the extending direction, which is opposite to the first connecting body 411, i.e., the rear end in the illustrated embodiment, is continuous with the connecting protrusion 416.

[0265] The second coupling body 412 is continuous with the second coupling arm 422. The second coupling body 412 supports the second coupling arm 422 at the upper side.

[0266] The second coupling body 412 may be any shape that can be accommodated in the second coupling member accommodating portion 312 and can support the second coupling arm 422. In the illustrated embodiment, the second coupling body 412 is configured to extend in the front-to-back direction and has a width in the left-right direction and a thickness in the up-down direction.

[0267] At this time, the length of the second coupling body 412 in the width direction, that is, the length in the left-right direction may be formed to be smaller than the length of the first coupling body 411 in the width direction.

[0268] The second connection body 412 is surrounded by the support arms 440. That is, as described later, the second connection body 412 is disposed between the pair of support arms 440 and spaced apart from the support arms 441 and 442.

[0269] The pressurizing protrusion 413 is formed to protrude from the upper side of the first coupling body 411. The operator can pressurize the pressurizing protrusion 413 to couple the coupling member 400 to the coupling member assembly and disassembly part 300. As described above, in the embodiment where the coupling member 400 and the coupling member assembly and disassembly part 300 are hook-coupled, the pressurizing protrusion 413 can be applied with an external force for hook coupling.

[0270] In addition, when the power electronic device 20 is coupled to the terminal member 10 , the pressurizing protrusion 413 protrudes outward. The operator can pressurize the pressurizing protrusion 413 to release the coupling state between the support member 140 and the coupling arm 420 , and then separate the power electronic device 20 from the terminal member 10 .

[0271] The pressurizing protrusion 413 is continuous with the first combination body 411. In the illustrated embodiment, the lower side of the front of the pressurizing protrusion 413 is continuous with the first portion of the first combination body 411, and the lower side of the rear of the pressurizing protrusion 413 is continuous with the second portion of the first combination body 411. The pressurizing protrusion 413 is configured to cover the guide portion 430 located between the first portion and the second portion of the first combination body 411 at the upper side.

[0272] The pressurizing protrusion 413 may be formed to have a width having the same length as the first coupling body 411. The upper side of the pressurizing protrusion 413 is recessed to form a weight-reducing groove 413a, thereby improving the processing convenience of the pressurizing protrusion 413. In addition, the friction force of the upper side of the pressurizing protrusion 413 is increased by the weight-reducing groove 413a, thereby making it easy to perform the coupling process of the coupling member 400 and the coupling member assembly and disassembly part 300 and the separation process of the power electronic device 20 and the terminal member 10.

[0273] The pressurizing groove 414 is formed concavely inside the coupling protrusion 416. When the coupling member 400 needs to be separated from the coupling member assembly and disassembly unit 300, the coupling protrusion 416 is pressurized toward the first coupling body 411, that is, the front side in the illustrated embodiment. At this time, due to the formation of the pressurizing groove 414, the friction force generated on the surface of the coupling protrusion 416 is increased, thereby reducing the size of the external force that the operator needs to apply.

[0274] That is, the pressurizing groove 414 increases the frictional force of the coupling protrusion 416 , thereby allowing the operator to easily hold and pressurize the coupling protrusion 416 .

[0275] The pressurizing groove 414 is formed concavely on the side of the surface of the coupling protrusion 416 opposite to the first coupling body 411, that is, the rear side in the illustrated embodiment. As described later, the side is defined as the second supporting surface 416b.

[0276] The plate receiving groove 415 is a space formed inside the first coupling body 411. The first guide plate 331 and the second guide plate 332 of the component guide 330 are received in the plate receiving groove 415 so as to be drawn out.

[0277] The board receiving groove 415 is partially surrounded by the first coupling body 411 and the pressurizing protrusion 413. In the illustrated embodiment, the front side of the board receiving groove 415 is surrounded by the first portion of the first coupling body 411, and the rear side of the board receiving groove 415 is surrounded by the second portion of the first coupling body 411. The upper side of the board receiving groove 415 is covered by the pressurizing protrusion 413.

[0278] The lower side of the board receiving groove 415 is open, and the first guide plate 331 and the second guide plate 332 can be led out to receive the board receiving groove 415. The outer sides in the width direction of the board receiving groove 415, i.e., the left and right sides in the illustrated embodiment, are connected to the outside through the first guide groove 431a and the second guide groove 431b.

[0279] Therefore, it can be understood that the guide plates 331 and 332 accommodated in the plate accommodating groove 415 can also be movably inserted into the guide grooves 431a and 431b, respectively.

[0280] A guide rib 432 is disposed inside the plate receiving groove 415. The guide rib 432 is inserted into a rib receiving portion 333 formed between the plurality of guide plates 331 and 332.

[0281] The coupling protrusion 416 is a portion where the coupling member 400 is coupled to the support member 140 of the connection terminal member 10. The coupling protrusion 416 may be hook-coupled with the second extension arm 142 of the support member 140.

[0282] The coupling protrusion 416 is continuous with the second coupling body 412. Specifically, the coupling protrusion 416 is continuous with the other side of the end portion in the extension direction of the second coupling body 412 opposite to the first coupling body 411, that is, the rear side end portion in the illustrated embodiment.

[0283] The coupling protrusion 416 may be formed to protrude relative to the second coupling body 412. The coupling protrusion 416 may be hook-coupled with the second extension arm 142 through the protrusion. In the illustrated embodiment, the coupling protrusion 416 is formed to protrude upward relative to the second coupling body 412.

[0284] The coupling protrusion 416 may be formed to have the same width as the second coupling body 412. In other words, the coupling protrusion 416 is formed to have a width shorter than that of the first coupling body 411. Thus, the coupling protrusion 416 is spaced apart from the support arms 440 between the plurality of support arms 440.

[0285] The coupling protrusion 416 may include a plurality of surfaces. Each surface may be continuous in a manner of forming a predetermined angle with each other. In the illustrated embodiment, the coupling protrusion 416 includes a first supporting surface 416a and a second supporting surface 416b.

[0286] The first supporting surface 416 a is formed on a surface of the coupling protrusion 416 that faces the first coupling body 411 , which is the front side surface in the illustrated embodiment. The first supporting surface 416 a is continuous with the second coupling body 412 .

[0287] The first support surface 416a extends in a manner that forms a predetermined angle with the second connecting body 412. In the illustrated embodiment, the first support surface 416a extends obliquely in a direction opposite to the first connecting body 411 in a manner that forms an obtuse angle with the upper side surface of the second connecting body 412. In other words, the first support surface 416a extends obliquely toward the lower side in the front and toward the upper side in the rear.

[0288] If the coupling member 400 is coupled to the supporting member 140, the first supporting surface 416a contacts the fifth extension surface 142e of the second extension arm 142. That is, the first supporting surface 416a contacts the fifth extension surface 142e and is supported by the fifth extension surface 142e. To this end, the first supporting surface 416a and the fifth extension surface 142e may extend in a manner having the same inclination.

[0289] The first supporting surface 416 a is continuous with the second supporting surface 416 b via the upper side surface of the coupling protrusion 416 .

[0290] The second supporting surface 416b is formed on the other surface of the coupling protrusion 416 opposite to the first coupling body 411, that is, the rear side surface in the illustrated embodiment. The second supporting surface 416b is continuous with the first supporting surface 416b.

[0291] The second support surface 416b extends in a manner that forms a predetermined angle with the upper side surface of the coupling protrusion 416. In the illustrated embodiment, the second support surface 416b forms an obtuse angle with the upper side surface of the coupling protrusion 416 and extends obliquely in a direction opposite to the first coupling body 411. In other words, the second support surface 416b extends in a manner that is inclined toward the upper side in the front and toward the lower side in the rear.

[0292] When the coupling member 400 moves toward the supporting member 140, the second supporting surface 416b contacts the third extending surface 142c of the second extending arm 142. As the coupling member 400 moves, the second extending arm 142 moves along the second supporting surface 416b toward the upper side of the coupling protrusion 416 and enters the space between the first supporting surface 416a and the first coupling body 411. Thus, the coupling member 400 and the supporting member 140 can be hooked.

[0293] To this end, the second supporting surface 416b and the third extending surface 142c may be formed to have the same inclination.

[0294] The coupling arm 420 is a portion where the coupling member 400 is coupled to the coupling member attaching and detaching portion 300. The coupling arm 420 can be detachably coupled to the coupling member attaching and detaching portion 300. Thus, the coupling member 400 and the cover body 200 can be hooked together.

[0295] The coupling arm 420 is continuous with the coupling body 410. The coupling arm 420 is continuous with one side of the coupling body 410 that faces the coupling member attachment and detachment portion 300, that is, the lower end portion in the illustrated embodiment.

[0296] The plurality of coupling arms 420 may be provided. The plurality of coupling arms 420 are respectively continuous with the first coupling body 411 and the second coupling body 412 , and respectively penetrate and couple with the plurality of coupling openings 320 .

[0297] In the illustrated embodiment, the combining arm 420 includes a first combining arm 421 and a second combining arm 422 .

[0298] The first connecting arm 421 is continuous with the first connecting body 411 and penetrates and connects to the first connecting opening 321. The first connecting arm 421 is detachably connected to the inner top surface of the second cover body 220 in the outer periphery of the first connecting opening 321.

[0299] The first connecting arm 421 is continuous with the lower end of the first portion, ie, the front portion, of the first connecting body 411. The first connecting arm 421 extends along the height direction of the first connecting body 411, ie, in the vertical direction in the illustrated embodiment.

[0300] The first coupling arm 421 may be formed to have a width shorter than that of the first coupling body 411. In addition, the first coupling arm 421 may be formed to be less than the length of the first coupling opening 321 in the width direction, ie, the left-right direction.

[0301] In the illustrated embodiment, the first combining arm 421 includes a first combining extension portion 421 a and a first combining protrusion 421 b .

[0302] The first connecting extension portion 421 a is a portion where the first connecting arm 421 is continuous with the first connecting body 411 . The first connecting extension portion 421 a passes through the first connecting opening portion 321 .

[0303] The first connecting extension 421a extends downward at the lower end of the first connecting body 411. One end of the first connecting extension 421a in the extending direction, i.e., the upper end in the illustrated embodiment, is continuous with the first portion of the first connecting body 411. The other end of the first connecting extension 421a in the extending direction, i.e., the lower end in the illustrated embodiment, is provided with a first connecting protrusion 421b.

[0304] The first coupling protrusion 421b is a portion where the first coupling arm 421 is hooked with the coupling member attaching and detaching portion 300. The first coupling protrusion 421b is formed at the other end portion of the first coupling extension portion 421a, ie, the lower end portion in the illustrated embodiment.

[0305] The first coupling protrusion 421b is formed to protrude outward from the first coupling extension 421a. In the illustrated embodiment, the first coupling protrusion 421b is formed to protrude toward the front side. At this time, the first coupling protrusion 421b includes a first portion extending horizontally and a second portion continuous with the first portion and extending the first coupling extension 421b obliquely downward.

[0306] The first coupling arm 421 may be pressed inwardly, ie, rearwardly in the illustrated embodiment, so that the first coupling arm 421 passes through the first coupling opening 321. At this time, the first portion may contact the outer periphery of the first coupling opening 321 and be pressed rearwardly.

[0307] If the first coupling protrusion 421b completely penetrates the first coupling opening 321, the pressurized state is released and the first coupling arm 421 can move forward. At this time, the second portion contacts the surface of the outer periphery of the first coupling opening 321 located inside the second cover body 220. Thus, the first coupling arm 421 and the hook of the coupling member assembly and disassembly part 300 are coupled.

[0308] The second connecting arm 422 is continuous with the second connecting body 412 and penetrates and connects to the second connecting opening 322. The second connecting arm 422 is detachably connected to the inner top surface of the second cover body 220 in the outer periphery of the second connecting opening 322.

[0309] The second connecting arm 422 is continuous with the lower end of the second connecting body 412. The second connecting arm 422 is formed to extend along the height direction of the second connecting body 412, that is, in the up-down direction in the illustrated embodiment.

[0310] The second coupling arm 422 may be formed to have a width shorter than that of the second coupling body 412. In the illustrated embodiment, the second coupling arm 422 may be formed to be less than the length of the second coupling opening 322 in the width direction, ie, the left-right direction.

[0311] In the illustrated embodiment, the second combining arm 422 includes a second combining extension 422 a and a second combining protrusion 422 b .

[0312] The second connecting extension portion 422a is a portion where the second connecting arm 422 and the second connecting body 412 are continuous. The second connecting extension portion 422a passes through the second connecting opening portion 322.

[0313] The second connecting extension 422a extends downward from the lower end of the second connecting body 412. One end of the second connecting extension 422a in the extending direction, i.e., the upper end in the illustrated embodiment, is continuous with the second connecting body 412. The other end of the second connecting extension 422a in the extending direction, i.e., the lower end in the illustrated embodiment, is provided with a second connecting protrusion 422b.

[0314] The second coupling protrusion 422b is a portion where the second coupling arm 422 is hooked with the coupling member attaching and detaching portion 300. The second coupling protrusion 422b is formed at the other end portion of the second coupling extension portion 422a, ie, the lower end portion in the illustrated embodiment.

[0315] The second coupling protrusion 422b is formed to protrude outward from the second coupling extension 422a. In the illustrated embodiment, the second coupling protrusion 422b is formed to protrude toward the rear side. At this time, the second coupling protrusion 422b includes a first portion extending horizontally and a second portion continuous with the first portion and extending obliquely toward the second coupling extension 422a downward.

[0316] The second coupling arm 422 may be pressed inward, ie, forward in the illustrated embodiment, so that the second coupling arm 422 passes through the second coupling opening 322. At this time, the second portion may contact the outer periphery of the second coupling opening 322 and be pressed forward.

[0317] If the second coupling protrusion 422b completely penetrates the second coupling opening 322, the pressurized state is released and the second coupling arm 422 can move forward. At this time, the second portion contacts the surface of the outer periphery of the second coupling opening 322 located inside the second cover body 220. Thus, the second coupling arm 422 is coupled to the hook of the coupling member assembly and disassembly portion 300.

[0318] Therefore, the coupling member 400 can be hooked with the coupling member attachment and detachment part 300 through the plurality of coupling arms 420. At this time, due to the shapes of the coupling protrusions 421b and 422b, the operator can couple the coupling member 400 and the coupling member attachment and detachment part 300 only by pressing the coupling member 400 against the coupling member attachment and detachment part 300.

[0319] In addition, due to the shape of the coupling protrusions 421b, 422b, the coupling member 400 and the coupling member attachment and detachment portion 300 are hooked together. Therefore, as long as no external force in a predetermined direction is applied, the coupling state of the coupling member 400 and the coupling member attachment and detachment portion 300 can be stably maintained.

[0320] In addition, the first connecting arm 421 and the second connecting arm 422 can be formed symmetrically along the front-to-back direction. Thus, the processability of the connecting member 400 can be improved. In addition, the connecting member 400 can be easily connected and separated from the cover body 200. Furthermore, the connecting member 400 connected to the cover body 200 will not shake in any direction, especially in the front-to-back direction separated by the first connecting arm 421 and the second connecting arm 422.

[0321] The guide portion 430 guides the coupling member 400 so that the coupling member 400 is coupled to the coupling member attachment and detachment portion 300 in a predetermined direction. The guide portion 430 is movably coupled to the member guide portion 330 of the coupling member attachment and detachment portion 300. The coupling member 400 and the coupling member attachment and detachment portion 300 can be coupled to or separated from each other in a state where the guide portion 430 and the member guide portion 330 are coupled.

[0322] The guide portion 430 is continuous with the coupling body 410. Specifically, the guide portion 430 is located on one side of the coupling body 410 that faces the coupling component assembly and disassembly portion 300, that is, the lower side in the illustrated embodiment. The guide portion 430 is located between the first portion (i.e., the front side portion) and the second portion (i.e., the rear side portion) of the first coupling body 411.

[0323] In the illustrated embodiment, the guide portion 430 includes a guide groove 431 and a guide rib 432 .

[0324] The guide groove 431 is a space into which the guide plates 331 and 332 of the component guide portion 330 are movably inserted. The guide groove 431 is formed to extend along the extending direction of the guide plates 331 and 332, that is, the up-down direction in the illustrated embodiment.

[0325] The guide groove 431 is formed in the first coupling body 411. In the illustrated embodiment, the guide groove 431 is formed in the width direction of the first coupling body 411, that is, on the left and right sides. The guide groove 431 is formed through the left and right sides of the first coupling body 411.

[0326] The guide groove 431 is communicated with the board receiving groove 415. A portion of the guide plates 331 and 332 may be received in the board receiving groove 415, and another portion of the guide plates 331 and 332 may be movably inserted into the guide groove 431.

[0327] The guide groove 431 may be formed to have a length greater than the thickness of the guide plates 331 , 332 , that is, a length greater than the length in the front-rear direction in the illustrated embodiment.

[0328] A plurality of guide grooves 431 may be provided. The plurality of guide grooves 431 are formed at different positions of the first coupling body 411 and can accommodate different guide plates 331 and 332 in a movably manner.

[0329] In the illustrated embodiment, the guide groove 431 includes a first guide groove 431 a and a second guide groove 431 b .

[0330] The first guide groove 431a is formed through the left side of the first coupling body 411. The first guide plate 331 is inserted and coupled to the first guide groove 431a in a movably manner.

[0331] The second guide groove 431b is formed through the right side surface of the first coupling body 411. The second guide plate 332 is inserted and coupled to the second guide groove 431b in a movably manner.

[0332] A guide rib 432 is formed between the first guide groove 431 a and the second guide groove 431 b .

[0333] The guide rib 432 is movably inserted into the rib receiving portion 333 of the member guide portion 330. The guide rib 432 is formed to extend in the extending direction of the guide plates 331 and 332, that is, in the up-down direction in the illustrated embodiment.

[0334] The guide rib 432 is continuous with the first coupling body 411. In the illustrated embodiment, the guide rib 432 is formed to protrude from the front side of the second portion of the first coupling body 411 toward the front side.

[0335] The height of the guide rib 432 may extend to a height shorter than the height of the first coupling body 411. At this time, one end of the guide rib 432 in the extending direction, that is, the lower end in the illustrated embodiment, may be located at the same height as the lower end of the second portion of the first coupling body 411.

[0336] Therefore, the second portion of the first coupling body 411 and the guide rib 432 can be placed together in the portion of the top surface 222 surrounding the second coupling opening 322. Thus, even when the power electronic device 20 vibrates in the up-down direction, the coupling state of the coupling member 400 and the coupling member attachment and detachment portion 300 can be stably maintained.

[0337] The guide rib 432 may be formed to have a thickness less than the width of the rib accommodation portion 333. Thus, the guide rib 432 may be easily inserted into the rib accommodation portion 333 and easily drawn out from the rib accommodation portion 333.

[0338] The support arm 440 provides a restoring force to the coupling member 400. When the coupling member 400 and the power electronic device 20 coupled thereto vibrate in the vertical direction, the support arm 440 deforms to store the restoring force, thereby buffering the impact caused by the generated vibration.

[0339] Thus, even if a separate elastic member such as a spring is not provided in the coupling member 400 , the coupling state between the power electronic device 20 and the terminal member 10 can be stably maintained.

[0340] When the coupling member 400 is coupled to the coupling member attachment and detachment portion 300, the support arm 440 extends downwardly from the lower end of the coupling body 410. In other words, when no external force is applied, the coupling member 400 is supported by the support arm 440 in contact with the top surface 222, and the coupling body 410 is spaced apart from the top surface 222.

[0341] In this state, when vibration occurs in the up-down direction, the support arm 440 may be deformed and the coupling member 400 may descend, and the coupling body 410 may contact the top surface 222. In addition, if the vibration is released, the support arm 440 is deformed and the elastic force stored is restored, and the coupling body 410 may be separated from the top surface 222 again.

[0342] Therefore, even if vibration in the vertical direction occurs in the connection terminal member 10 and the power electronic device 20 coupled thereto, the vibration can be buffered by the support arm 440. Thus, damage to the connection terminal member 10 and the power electronic device 20 can be prevented. Furthermore, damage to the coupling member 400 coupled to the connection terminal member 10 and the power electronic device 20 can be prevented.

[0343] The support arm 440 is continuous with the coupling body 410. Specifically, the support arm 440 is continuous with the second portion (ie, the rear portion) of the first coupling body 411. The support arm 440 extends obliquely from the rear side of the second portion of the first coupling body 411 toward the rear lower side.

[0344] One end of the support arm 440 in the extending direction, i.e., the upper end in the front in the illustrated embodiment, is continuous with the second portion of the first connecting body 411. The other end of the support arm 440 in the extending direction, i.e., the lower end in the rear in the illustrated embodiment, is located below the lower end of the first connecting body 411 and the lower end of the second connecting body 412. With the above structure, the support arm 440 can elastically support the connecting member 400.

[0345] The support arm 440 is disposed apart from the second coupling body 412 and the coupling protrusion 416. The support arm 440 partially surrounds the second coupling body 412 and the coupling protrusion 416 at the outer side in the width direction thereof.

[0346] The supporting arms 440 may be provided in plural. The plural supporting arms 440 may be combined with the combining body 410 at different positions, and contact the top surface 222 at different positions, so as to elastically support the combining member 400. In the illustrated embodiment, the supporting arms 440 are provided in two, including a first supporting arm 441 and a second supporting arm 442.

[0347] The first support arm 441 and the second support arm 442 are spaced apart from each other and are disposed opposite to each other via the second combining body 412 and the combining protrusion 416. In one embodiment, the first support arm 441 and the second support arm 442 may extend to the same length.

[0348] The first support arm 441 is continuous with the left side portion of the rear of the second portion of the first combined body 411. The first support arm 441 surrounds the second combined body 412 and the combined protrusion 416 on the left side and extends obliquely downward. The lower end of the first support arm 441 may be located at a position lower than the lower end of the combined body 410.

[0349] The second support arm 442 is continuous with the right side portion of the rear of the second portion of the first combined body 411. The second support arm 442 surrounds the second combined body 412 and the combined protrusion 416 on the right side and extends obliquely downward. The lower end of the second support arm 442 may be located at a position lower than the lower end of the combined body 410.

[0350] 5. Description of the process of combining the terminal block member 10 and the power electronic device 20 according to the embodiment of the present invention

[0351] The power electronic device 20 of the embodiment of the present invention includes a coupling member 400. The coupling member 400 is detachably coupled to the coupling member assembly and disassembly portion 300 of the power electronic device 20. Therefore, in addition, the coupling member 400 is detachably coupled to the support member 140 of the terminal member 10. In one embodiment, the coupling member 400 can be hooked to the coupling member assembly and disassembly portion 300 and the support member 140, respectively.

[0352] In the case of conventional power electronic devices, the connection terminal member is directly connected to the structure provided integrally with the power electronic device itself. Therefore, if the structure is damaged, there is a problem that the entire cover of the power electronic device needs to be replaced.

[0353] In addition, in conventional power electronic devices, various devices contained inside are usually provided integrally with a cover, so there is a problem that the internal devices also need to be disassembled when replacing the cover.

[0354] Therefore, the time and cost required to maintain the structure combining the power electronic device and the terminal member are too high. In addition, there is a concern that in the process of disassembling an electrical component that does not require maintenance, the electrical component may be accidentally damaged.

[0355] On the contrary, when the coupling member 400 of the embodiment of the present invention is damaged, only the coupling member 400 can be replaced to complete the maintenance work. Therefore, not only the time and cost required for maintenance are saved, but also the coupling state of sensitive electrical components will not be damaged, so the service life and operation reliability of the power electronic device 20 can be improved.

[0356] Furthermore, the coupling member 400 is elastically supported by the support arm 440. Therefore, the vibration generated by the operation of the power electronic device 20 and the terminal member 10 can be buffered by the coupling member 400. Thus, it is possible to prevent the structure of the power electronic device 20 from being damaged by the vibration. Furthermore, there is no need to separately provide an elastic member for vibration buffering, thereby improving the assembly performance and saving the manufacturing cost.

[0357] Below, refer to Figures 16 to 23 , the process and state of combining the power electronic device 20 and the terminal member 10 according to the embodiment of the present invention are described in detail.

[0358] (1) Description of the process of joining the power electronic device 20 and the joining member 400 according to the embodiment of the present invention

[0359] Reference Figures 16 to 20 , shows a process of combining the combining member 400 with the combining member attaching and detaching portion 300 of the power electronic device 20 according to the embodiment of the present invention and a combined state.

[0360] Reference Fig.16 , the coupling member 400 moves from the upper side to the lower side and is coupled to the coupling member assembly and disassembly part 300. As described above, the front side, the left side and the right side of the coupling member assembly and disassembly part 300 are surrounded by the second frame 221, the lower side thereof is surrounded by the top surface 222, and the upper side and the rear side are open. The coupling member 400 is coupled to the coupling member assembly and disassembly part 300 through the upper side.

[0361] Reference Fig.17 , showing the process of combining the combining member 400 with the combining member assembly and disassembly portion 300.

[0362] Reference Fig.17In (a), the coupling member 400 is located on the upper side of the coupling member attachment and detachment portion 300 . At this time, the first coupling arm 421 is disposed on the upper side of the first coupling opening 321 , and the second coupling arm 422 is disposed on the upper side of the second coupling opening 322 .

[0363] Reference Fig.17 (b), the second coupling arm 422 is first inserted into the second coupling opening 322. In the illustrated embodiment, the coupling member 400 is rotated in the clockwise direction so that the second coupling arm 422 on the rear side is first inserted into the second coupling opening 322 on the rear side.

[0364] Reference Fig.17 (c), the first coupling arm 421 is inserted into the first coupling opening 321. In the illustrated embodiment, the coupling member 400 is rotated in the counterclockwise direction so that the first coupling arm 421 on the front side is inserted into the first coupling opening 321 on the front side.

[0365] At this time, the member guide portion 330 and the guide portion 430 are also movably coupled to each other, thereby being able to guide the accurate coupling of the coupling member 400 and the coupling member attaching and detaching portion 300 .

[0366] Reference Figures 18 to 20 , showing a state in which the coupling member 400 and the coupling member attaching and detaching portion 300 are coupled.

[0367] First, the first coupling arm 421 penetrates the first coupling opening 321, so that the first coupling protrusion 421b is coupled with the front side hook of the upper inner surface of the second cover body 220. Similarly, the second coupling arm 422 penetrates the second coupling opening 322, so that the second coupling protrusion 422b is coupled with the rear side hook of the upper inner surface of the second cover body 220.

[0368] Therefore, it is possible to prevent the coupling member 400 and the coupling member attaching and detaching portion 300 from being separated at will.

[0369] The first guide plate 331 and the second guide plate 332 are inserted into the first guide groove 431a and the second guide groove 431b, respectively, so as to be movable in the up-down direction. In addition, the guide rib 432 is inserted into the rib receiving portion 333 so as to be movable in the up-down direction.

[0370] Therefore, the movement of the coupling member 400 in the front-rear direction and the left-right direction is restricted by the coupling of the member guide portion 330 and the guide portion 430 .

[0371] At this time, the coupling member 400 is elastically supported by the support arm 440 in contact with the top surface 222. That is, the remaining structure of the coupling member 400 except the lower end of the support arm 440 is separated from the top surface 222.

[0372] Therefore, even when vibration is generated in the power electronic device 20 , the impact caused by the generated vibration can be mitigated by the elastic force applied by the support arm 440 .

[0373] (2) Description of the process of combining the terminal member 10 and the power electronic device 20 according to the embodiment of the present invention

[0374] Reference Figure 21 to Figure 23 , showing the process and state of combining the power electronic device 20 and the terminal member 10 according to the embodiment of the present invention. It can be understood that, in the power electronic device 20, the combining member 400 is in a detachable combined state in the illustrated embodiment.

[0375] Reference Fig.21 , the power electronic device 20 moves from the front side to the rear side and is combined with the terminal member 10. At this time, the protrusion (not shown) formed on the lower side of the second cover 220 is arranged to overlap with the base groove 131 in the front-to-back direction, the terminal member 240 is arranged to overlap with the groove member 120 in the front-to-back direction, the fastening support portion 250 is arranged to overlap with the fastening hole 160 in the front-to-back direction, and the coupling member 400 is arranged to overlap with the support member 140 in the front-to-back direction.

[0376] Reference Fig. 22 , showing the order of combining the power electronic device 20 with the terminal member 10. In the illustrated embodiment, the power electronic device 20 is rotated in a counterclockwise direction so that the protrusion (not shown) formed on the lower side of the second cover 220 is first inserted into the base groove 131 ( Fig. 22 ①).

[0377] Next, the power electronic device 20 is rotated in the clockwise direction, so that the terminal member 240 is combined with the slot member 120, and the combining member 400 is combined with the supporting member 140 ( Fig. 22 ②). Although not shown, a process of combining the fastening member 260 with the fastening support part 250 and the fastening hole 160, respectively, may also be performed.

[0378] Reference Fig.23 , showing a state where the power electronic device 20 is combined with the connection terminal member 10 .

[0379] The second extension arm 142 is pressed upward and moved backward by the combination with the protruding portion 416. At this time, the third extension surface 142c contacts the second support surface 416b and moves upward along the second support surface 416b.

[0380] If the movement of the power electronic device 20 is completed, the second extension arm 142 is accommodated in the space formed between the coupling protrusion 416 and the first coupling body 411. At this time, the fifth extension surface 142e contacts the first support surface 416a.

[0381] In this state, the support member 140 presses the coupling member 400 downward due to its shape. In addition, the coupling member 400 is pressed upward by the elastic force applied by the support arm 440. Thus, the power electronic device 20 and the terminal member 10 can be stably hooked.

[0382] In this state, when it is necessary to separate the power electronic device 20 and the terminal member 10, if the pressurizing protrusion 413 is pressed, the support arm 440 is compressed and the coupling member 400 moves downward. Thus, when the support member 140 and the coupling member 400 are separated, the power electronic device 20 can move forward and be separated from the terminal member 10.

[0383] Although the embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments presented in this specification. A person skilled in the art who understands the concept of the present invention can easily propose other embodiments within the scope of the same concept by adding, changing, deleting, or appending constituent elements, and these also fall within the scope of the concept of the present invention.
