Description

[Technical Field]

[0001]

[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 that can easily couple a power electronic device and a terminal member that communicates with and is energized by the power electronic device, and a power electronic device including the same. [Background technology]

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

[0003]

[0003] Traditionally, PLCs were installed in a single device and only provided a preset power capacity. However, recently, PLCs have been installed in a modular form, and a configuration has been adopted in which the power capacity can be varied depending on the number of power electronic devices installed. For this reason, multiple PLCs are connected to a device called a base.

[0004]

[0004] As PLCs are provided in a modular form, not only can the power capacity be changed, but also a problematic PLC can be separated from multiple PLCs, repaired, and then reconnected to the base. As a result, modular PLCs are becoming increasingly popular.

[0005] However, since the PLC is removably coupled to the base, various problems arise, which are different from those in the past when the PLC was fixedly coupled to the base.

[0006] First, there is a risk that the PLC and the base may be incompletely coupled, causing the PLC and the base to be damaged and separated at random. Also, there is a risk that the portion where the PLC and the base are coupled may be damaged due to the inexperience of the operator.

[0007] On the other hand, when repairing a modular PLC, the cover of the PLC must be removed to replace the problematic part.

[0008]

[0008] Considering that the cover of a typical PLC is formed as a single unit to maintain rigidity, when the cover is disassembled and reassembled to repair the corresponding part, it is difficult to maintain the same rigidity as before the repair. As a result, excessive time and cost are required for maintenance, and there is a risk that work convenience and user satisfaction will decrease.

[0009]

[0009] Furthermore, if the PLC cover is provided as an integrated unit, excessive stress may occur at the joint between the PLC and the base due to vibrations that occur when the PLC and the base are operated or shocks that occur when the PLC and the base are connected and disconnected. In this case, the possibility of damage to the joint increases, and if the PLC cover is formed as an integrated unit, the entire cover must be replaced to repair the joint.

[0010]

[0010] Furthermore, when the PLC components and the cover are integrated, components such as the PCB must also be separated to replace the cover, which can damage the PLC components and reduce operational reliability during reassembly.

[0011] Korean Patent Publication No. 10-1342513 discloses an assembly-type base for an electronic watt-hour meter. Specifically, the terminal base is configured so that an input terminal block and an output terminal block can be attached and detached in an assembly-type manner, thereby enabling the power capacity of the watt-hour meter to be varied.

[0012] However, the assembly-type base of the electronic watt-hour meter disclosed in the prior art document merely provides a method for detachably connecting the input / output terminal blocks in an assembly-type manner to change the power capacity. That is, the prior art document does not provide a method for preventing damage to the terminal blocks or the assembly-type base that may occur due to impacts that occur when connecting or disconnecting the input / output terminal blocks and the assembly-type base.

[0013] Korean Patent Registration No. 10-1011034 discloses a modularized measurement instrument integration system in which a measurement circuit case is modularized. Specifically, the system discloses a modularized measurement instrument integration system in which the measurement instruments are modularized and detachably mounted on a base, allowing the number of measurement instrument modules to be changed.

[0014] However, the modularized instrument integration system disclosed in the prior art, which modularizes the case of the measurement circuit, requires a separate guide to support the connected instrument module. Also, the prior art is configured such that the base module supports the instrument module from below, which has limitations that make it difficult to apply to other directions, such as the front-to-back or left-to-right directions.

[0015]

[0015] Furthermore, the prior art documents do not provide a method for reducing vibrations generated during operation of the PLC and for maintaining the coupling state between the PLC and the base.

[0037]

[0038] In this case, the guide plate may include a first guide plate positioned to be biased toward one side in the left-right direction; and a second guide plate positioned to be biased toward the other side in the left-right direction and spaced apart from the first guide plate, and the guide groove may include a first guide groove formed to penetrate in the vertical direction on a left side surface of the combination body and movably accommodate the first guide plate; and a second guide groove formed to penetrate in the vertical direction on a right side surface of the combination body and movably accommodate the second guide plate.

[0041]

[0042] At this time, the coupling body may be provided with a power electronic device including a pressure groove recessed into the second support surface.

[0042]

[0043] In addition, the connecting body may include a first connecting body extending in a vertical direction; and a pressure protrusion formed to protrude upward from an upper end of the first connecting body, the pressure protrusion being provided on an external terminal member and exposed to the outside of a support member that is hook-coupled with the connecting member, in a power electronic device. [Effects of the Invention]

[0043]

[0044] With the above-described configuration, in the coupling member according to the embodiment of the present invention and the power electronic device including the same, the power electronic device and the terminal member can be coupled together by a separate member.

[0044]

[0045] The power electronic device is provided with a coupling member. The coupling member is detachably coupled to a coupling member detachment portion provided on the power electronic device. The coupling member includes a coupling arm extending toward the power electronic device. The coupling member detachment portion is formed through an upper surface of the housing and includes a coupling opening through which the coupling arm is retractably coupled.

[0045]

[0046] The coupling arm includes a coupling extension extending toward the coupling opening and penetrating the coupling opening, and a coupling protrusion protruding outward from an end of the coupling extension and hooked into the coupling opening.

[0046]

[0047] Therefore, when the coupling member and the coupling member detachment portion are coupled together, the coupling member and the housing of the power electronic device can be detachably coupled together.

[0047]

[0048] The connecting member includes a connecting body forming a body thereof and a connecting protrusion continuous with the connecting body. The connecting protrusion protrudes upward.

[0048]

[0049] The terminal member to which the connecting member is removably connected includes a support member having a first extension arm extending forward and a second extension arm extending from an end of the first extension arm toward the connecting member.

[0049]

[0050] When the power electronic device connected to the connecting member is moved toward the terminal member, the second extension arm is pressed by the connecting protrusion and deformed upward, storing a restoring force. When the connecting protrusion passes through the second extension arm, the second extension arm is restored to its original shape by the restoring force and hook-connects with the connecting protrusion.

[0050]

[0051] Accordingly, the power electronic device and the terminal member can be removably coupled by a single coupling member.

[0051]

[0052] Furthermore, with the above-described configuration, the coupling member according to the embodiment of the present invention and the power electronic device including the same can prevent damage to the power electronic device.

[0052]

[0053] As described above, the power electronic device and the terminal member are detachably connected via the connecting member. Therefore, if the connecting member is damaged, maintenance can be performed by removing only the connecting member. In other words, disassembly of the power electronic device is not required for maintenance of the connecting member.

[0053]

[0054] Therefore, only the connecting members can be separated for maintenance, and therefore damage to the power electronic device can be prevented.

[0054]

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

[0055]

[0056] The coupling member includes a support arm. The support arm is located at the lowest part 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 part of the part exposed to the outside. Therefore, the support arm contacts the upper surface of the housing and elastically supports the other components of the coupling member.

[0056]

[0057] When the power electronic device or the terminal member is operated and vibration occurs, the support arm is pressurized and deformed to store elastic force, thereby buffering the vibration of the power electronic device and minimizing the shock caused by the vibration transmitted to the power electronic device structure.

[0057]

[0058] Therefore, damage to the power electronic device due to vibrations can be prevented.

[0058]

[0059] Furthermore, with the above-described configuration, the coupling member according to the embodiment of the present invention and the power electronic device including the same can be prevented from being moved arbitrarily.

[0059]

[0060] The coupling member includes a guide portion. The guide portion is formed through left and right sides of the coupling body and includes a plurality of guide grooves extending in the up-down direction. A plurality of guide plates provided in the coupling member detachment portion are movably received in the guide grooves. The coupling between the guide plates and the guide grooves can prevent the power electronic device from moving in the forward-backward direction.

[0060]

[0061] The guide part also includes a plate receiving groove, which is a space recessed into the coupling body. The plate receiving groove is provided with guide ribs extending in the front-rear and up-down directions. The coupling member detachment part is provided with a rib receiving part, which is a space formed between a plurality of guide plates spaced apart from one another. The guide rib is received in the rib receiving part and is restrained in the left-right direction by the plurality of guide plates. The coupling of the guide rib and the rib receiving part can prevent the power electronic device from moving in the left-right direction.

[0061]

[0062] Thus, arbitrary movement of the power electronics can be prevented.

[0062]

[0063] Furthermore, with the above-described configuration, the coupling member according to the embodiment of the present invention and the power electronic device including the same can stably maintain the coupling state between the power electronic device and the terminal member.

[0063]

[0064] With the above-described configuration, the coupling member is hook-coupled to the power electronic device and the terminal member, respectively, and will not be detached from the power electronic device or the terminal member unless an external force is applied in a predetermined direction.

[0064]

[0065] The coupling member is provided with a support arm configured to buffer vertical vibrations applied to the power electronic device, thereby stably maintaining the coupling state between the power electronic device and the terminal member and the coupling member.

[0065]

[0066] The coupling member is provided with a guide portion, and the coupling member detachment portion is coupled to a member guide portion. The coupling of the guide portion and the member guide portion prevents the power electronic device from moving in the forward / backward and left / right directions.

[0066]

[0067] Therefore, the coupling member is stably coupled to the power electronic device and the terminal member, vibrations in the up-down direction are damped, and arbitrary movement in the front-back and left-right directions is prevented, so that the coupling state of the coupling member, the power electronic device, and the terminal member can be stably maintained.

[0067]

[0068] 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.

At this time, the coupling and separation of the terminal member 10 and the power electronic device 20 can be easily performed by the coupling member 400, which will be described in detail later.

[0082]

[0100] In the embodiment shown in FIGS. 3 to 5, the terminal member 10 includes a terminal body 100. As shown in FIG.

[0083]

In the illustrated embodiment, the terminal body 100 is formed in the shape of a rectangular plate having a length in the left-right direction and a height in the up-down direction.

[0084]

[0102] In the above embodiment, one side of the terminal body 100 where the power electronic device 20 is connected, that is, the front side in the illustrated embodiment, is formed open.

[0109] A slot member 120 is formed on one surface of the current-carrying member 110 facing the power electronic device 20, that is, on the front side in the illustrated embodiment.

[0092]

[0110] The slot member 120 is a portion where the terminal body 100 communicates with and is energized by the power electronic device 20. A terminal member 240 of the power electronic device 20 is inserted into the slot member 120 so as to be retractable. This coupling allows the slot member 120 and the terminal member 240 to communicate with and be energized, thereby enabling the terminal member 100 and the power electronic device 20 to communicate with and be energized.

[0093]

[0111] The slot member 120 may be formed in a shape corresponding to the shape of the terminal member 240. In the illustrated embodiment, the slot member 120 is a rectangular pillar that extends vertically and protrudes forward. An opening for receiving the terminal member 240 is recessed into the front side of the slot member 120.

[0094]

[0112] The slot member 120 may be disposed at a position corresponding to the positions of the base groove 131 of the support base 130 and the support member 140. The slot member 120 may also be disposed so as to correspond to the positions of the terminal member 240 of the power electronic device 20 coupled to the base groove 131 and the support member 140.

[0095]

[0113] In the illustrated embodiment, the slot member 120 is disposed to overlap the base groove 131 in the height direction, i.e., the vertical direction, but is positioned to be offset to the right side compared to the support member 140.

[0096]

[0114] A plurality of slot members 120 may be provided. The plurality of slot members 120 may be spaced apart from one another in the longitudinal direction of the terminal body 100. In the illustrated embodiment, ten slot members 120 are provided, and are spaced apart from one another in the left-right direction. The spacing between the slot members 120 may vary depending on the width of the housing 200 of the power electronic device 20, i.e., the left-right length in the illustrated embodiment.

[0097]

[0115] A support base 130 is located below the slot member 120 .

[0098]

[0116] The support base 130 supports the power electronic device 20 coupled to the terminal member 10 at one side in the height direction, i.e., the lower side in the illustrated embodiment. The support base 130 partially supports the rear side of the lower portion of the housing 200 of the power electronic device 20.

[0099]

[0117] The support base 130 is located at one end in the height direction of the terminal body 100, i.e., at the lower end in the illustrated embodiment. The support base 130 is formed to extend in the direction in which the power electronic device 20 is separated, i.e., toward the front in the illustrated embodiment.

[0100]

[0118] The support base 130 extends in the same direction as the terminal body 100. In the illustrated embodiment, the support base 130 extends in the left-right direction. One end of the support base 130 in the extension direction, that is, the left end in the illustrated embodiment, extends to the current-carrying member 110. The other end of the support base 130 in the extension direction, that is, the right end in the illustrated embodiment, extends to the right end of the terminal body 100.

[0101]

[0119] In the illustrated embodiment, the support base 130 includes a base groove 131 .

[0102]

[0120] A protrusion (not shown) formed on the lower part of the housing 200 of the power electronic device 20 mounted on the support base 130 is inserted into the base groove 131. The lower part of the power electronic device 20 can be stably fixed by the base groove 131.

[0103]

[0121] The base groove 131 is formed through the inside of the support base 130. The base groove 131 is formed to extend in the thickness direction of the support base 130, that is, in the vertical direction in the illustrated embodiment.

[0104]

[0122] The base groove 131 is formed to extend in the same direction as the support base 130. In the illustrated embodiment, the base groove 131 is formed to extend in the left-right direction.

[0105]

[0123] The base groove 131 may have any shape that allows a protrusion (not shown) provided on the housing 200 of the power electronic device 20 to be inserted and coupled in a retractable manner. In the illustrated embodiment, the base groove 131 has a rectangular cross section that has a length in the left-right direction, a width in the front-back direction, and a height in the up-down direction.

[0106]

[0124] At this time, the width of the base groove 131 in the front-rear direction may be formed to correspond to the length of the width of the protrusion (not shown) in the front-rear direction.

[0107]

[0125] A plurality of base grooves 131 may be formed. The plurality of base grooves 131 may be spaced apart from one another along the extension direction of the support base 130. The plurality of base grooves 131 may also be arranged to correspond to the positions of the slot member 120 and the support member 140.

[0108]

[0126] In the illustrated embodiment, ten base grooves 131 are formed corresponding to the number of slot members 120, and are spaced apart from one another in the left-right direction. Each base groove 131 is arranged to overlap with the slot members 120 and the support members 140 in the height direction, i.e., in the illustrated embodiment, in the up-down direction.

[0109]

[0127] The base groove 131 may be formed in any shape into which protrusions (not shown) provided on the housings 200 of the plurality of power electronic devices 20 can be inserted.

[0110]

[0128] For example, a single base groove 131 may be formed at each end of the extension direction of the support base 130, extending between the left end and the right end in the illustrated embodiment. In the illustrated embodiment, protrusions (not shown) provided on the housings 200 of the plurality of power electronic devices 20 may be inserted into the single base groove 131, respectively.

[0111]

[0129] Alternatively, a plurality of base grooves 131 may be provided, and the extension length of each base groove 131 may be longer than the widthwise length of the housing 200, or the left-right length in the illustrated embodiment. In the above embodiment, protrusions (not shown) provided on the housing 200 of the plurality of power electronic devices 20 may be inserted into each of the plurality of base grooves 131. That is, the number of base grooves 131 may be less than the number of power electronic devices 20, and each of the plurality of base grooves 131 may support a plurality of power electronic devices 20.

[0112]

[0130] The support base 130 faces the support member 140 across the slot member 120 .

[0113]

[0131] The support member 140 supports the power electronic device 20 connected to the terminal member 10 at the other side in the height direction, i.e., the upper side in the illustrated embodiment. The support member 140 is connected to a connecting member 400 connected to the connecting member detachment portion 300 of the power electronic device 20, and partially supports the rear side of the upper part of the power electronic device 20.

[0114]

[0132] The support member 140 is located at the other end in the height direction of the terminal body 100, i.e., at the upper end in the illustrated embodiment. The support member 140 protrudes in the direction in which the power electronic device 20 is separated, i.e., toward the front in the illustrated embodiment.

[0115]

[0133] The support member 140 is detachably coupled to a coupling member 400 provided on the power electronic device 20. In one embodiment, the support member 140 may be hook-fitted to the coupling member 400. Therefore, the coupled state between the support member 140 and the coupling member 400 may be maintained unless a predetermined force is applied in a preset direction.

[0116]

[0134] The support member 140 may be disposed at any position where it can be coupled to the coupling member 400 of the power electronic device 20. In the illustrated embodiment, the support member 140 is disposed in the height direction of the terminal body 100, i.e., in the up-down direction, so as to overlap with the slot member 120 and the base groove 131.

[0117]

[0135] A plurality of support members 140 may be provided. The plurality of support members 140 may be spaced apart from one another along the longitudinal direction of the terminal body 100. In the illustrated embodiment, ten support members 140 are provided and spaced apart from one another in the left-right direction.

[0118]

[0136] In the illustrated embodiment, the support member 140 includes a first extension arm 141 , a second extension arm 142 , a third extension arm 143 and a member receiving portion 144 .

[0119]

[0137] 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, toward the front in the illustrated embodiment. The first extension arm 141 forms the upper portion of the support member 140.

[0120]

[0138] The first extension arm 141 partially covers the upper side of the coupling member 400 and the coupling member attachment / detachment part 300 to which the coupling member 400 is attached. As will be described later, the first extension arm 141 also partially covers the upper side of the second coupling body 412 of the coupling member 400.

[0121]

[0139] Of the ends in the extension direction of the first extension arm 141, one end that is connected to the terminal body 100, i.e., the rear end in the illustrated embodiment, is continuous with the upper end of the terminal body 100. Of the ends in the extension direction of the first extension arm 141, the other end that faces the power electronic device 20, i.e., the front end in the illustrated embodiment, is continuous with the second extension arm 142.

[0122]

[0140] The second extension arm 142 is detachably coupled to a coupling protrusion 416 formed on an end of the second coupling body 412. In one embodiment, the second extension arm 142 may be coupled to the coupling protrusion 416 by a hook.

[0123]

[0141] At the same time, the second extension arm 142 presses the upper surface of the second connecting body 412. As a result, the connecting member 400 and the support member 140 are detachably connected to each other, but the connected state can be stably maintained.

[0124]

[0142] The second extension arm 142 is continuous with the first extension arm 141. The second extension arm 142 is continuous with the other end of the first extension arm 141, which is the front end in the illustrated embodiment.

[0125]

[0143] The second extension arm 142 may be divided into multiple sections. 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.

[0126]

[0144] 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 at a predetermined angle with the first extension arm 141. In the illustrated embodiment, the first extension surface 142a extends in a direction toward the lower front side at an obtuse angle with the first extension arm 141. In other words, the first extension surface 142a extends at an angle toward the lower front side and the upper rear side.

[0127]

[0145] 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 extends downward toward the coupling member 400 at an obtuse angle with the first extension surface 142a. In other words, the second extension surface 142b extends at an incline in the vertical direction.

[0128]

[0146] The third extension surface 142c is continuous with the second extension surface 142b at a predetermined angle. In the illustrated embodiment, the third extension surface 142c extends toward the connecting member 400, i.e., toward the rear downward direction, at an obtuse angle with the second extension surface 142b. In other words, the third extension surface 142c extends at an angle toward the front upper side and the rear lower side.

[0129]

[0147] When the power electronic device 20 is moved toward the terminal member 10, the third extension surface 142c comes into contact with the coupling protrusion 416 of the coupling member 400. At this time, the second support surface 416b of the coupling protrusion 416 extends at an angle corresponding to the third extension surface 142c. Therefore, the coupling member 400 can be easily inserted and coupled to the support member 140.

[0130]

[0148] The fourth extension surface 142d is continuous with the third extension surface 142c at a predetermined angle. In the illustrated embodiment, the fourth extension surface 142d extends toward the terminal body 100, i.e., toward the rear in the illustrated embodiment, at an obtuse angle with the third extension surface 142c. In other words, the fourth extension surface 142d extends at an angle in the front-to-rear direction.

[0131]

[0149] When the coupling member 400 is coupled to the support member 140, the upper surface of the second coupling body 412 of the coupling body 410 may come into contact with the fourth extension surface 142d, thereby stably maintaining the coupling state of the coupling member 400 coupled to the terminal member 10.

[0132]

[0150] The fifth extension surface 142e is continuous with the fourth extension surface 142d at a predetermined angle. In the illustrated embodiment, the fifth extension surface 142e extends toward the first extension arm 141, i.e., toward the upper rear side, at an obtuse angle with the fourth extension surface 142d. In other words, the fifth extension surface 142e extends at an angle downwards at the front and upwards at the rear.

[0133]

[0151] When the coupling member 400 is coupled to the support member 140, the fifth extension surface 142e comes into contact with the coupling protrusion 416 of the coupling body 410. At this time, the first support surface 416a of the coupling protrusion 416 may be extended to be inclined corresponding to the fifth extension surface 142e. Therefore, the coupling protrusion 416 is stably supported by the fifth extension surface 142e, and the coupled state of the coupling member 400 coupled to the terminal member 10 may be stably maintained.

[0134]

[0152] The third extension arm 143 reinforces the rigidity of the first extension arm 141. In addition, the third extension arm 143 limits the length to which the connecting member 400 is inserted into the support member 140.

[0135]

[0153] The third extension arm 143 is continuous with the first extension arm 141 at 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.

[0136]

[0154] 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 rearward of the first extension arm 141 and adjacent to the terminal body 100.

[0137]

[0155] A space formed by the first extension arm 141, the second extension arm 142, and the third extension arm 143 is defined as a member receiving portion 144.

[0138]

[0156] The member receiving portion 144 is a space that receives the coupling member 400. The member receiving 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 member receiving portion 144 is open on one side facing the power electronic device 20, that is, on the front side in the illustrated embodiment. The coupling member 400 can be inserted into or pulled out of the member receiving portion 144 through the one side.

[0139]

[0157] The component receiving portion 144 may be formed to have a height that is longer than the height of the coupling member 400, i.e., the length in the up-down direction. In addition, the component receiving portion 144 may be formed to have a length that is longer than the length of the coupling member 400, i.e., the length in the front-to-back direction. Accordingly, when the power electronic device 20 coupled to the terminal member 10 vibrates, the shock caused by the vibration may be buffered by the coupling member 400.

[0140]

[0158] The device receiving portion 150 is a space that receives a portion of the housing 200 of the power electronic device 20. In the illustrated embodiment, the device receiving portion 150 receives the left and right portions of the coupling member attachment / detachment portion 300 formed on the upper rear side of the second housing 220.

[0141]

[0159] The device receiving portion 150 may be formed to correspond to the shape of the remaining portion of the upper rear portion of the second housing 220 excluding the coupling member detachment portion 300. In the illustrated embodiment, the device receiving portion 150 is formed to extend in the left-right direction together with the terminal body 100.

[0142]

[0160] The device receiving portion 150 is open on one side facing the power electronic device 20, that is, the front side in the illustrated embodiment. The second housing 220 can be inserted into or pulled out from the device receiving portion 150 through the one side.

[0143]

[0161] In the illustrated embodiment, each side in the height direction of the other side of the device receiving portion 150, i.e., the upper and lower sides, is open. When the terminal member 10 or the power electronic device 20 connected thereto vibrates in the vertical direction, the power electronic device 20 vibrates through each side of the device receiving portion 150, and shock can be absorbed.

[0144]

[0162] A plurality of device receiving portions 150 may be formed. The plurality of device receiving portions 150 may be spaced apart from one another. In the illustrated embodiment, ten device receiving portions 150 are provided and are spaced apart from one another in the extension direction of the terminal body 100, i.e., in the left-right direction.

[0145]

[0163] A plurality of support members 140 are positioned between the plurality of equipment receiving portions 150. In other words, the plurality of support members 140 and the plurality of equipment receiving portions 150 are alternately arranged along the longitudinal direction of the terminal body 100.

[0146]

[0164] A fastening hole 160 is formed inside the device receiving portion 150 .

[0147]

[0165] The fastening hole 160 is a space into which the fastening member 260 of the housing 200 is inserted. The fastening hole 160 is recessed into one surface of the terminal body 100 surrounding the device receiving portion 150, that is, the front side surface in the illustrated embodiment.

[0148]

[0166] The fastening holes 160 may be positioned to correspond to the positions of the fastening members 260. In the illustrated embodiment, the fastening holes 160 are positioned inside the device housing 150 and offset to the right.

[0149]

[0167] The fastening hole 160 may be formed in any shape that allows the fastening member 260 to be inserted and coupled. In an embodiment in which the fastening member 260 is a screw member, the fastening hole 160 may have a screw thread formed on its inner circumferential surface.

[0150]

[0168] By coupling the fastening holes 160 and the fastening members 260, the upper portion of the power electronic device 20 can be coupled to the terminal member 10 by a plurality of members, i.e., the coupling members 400 and the fastening members 260. Accordingly, the coupled state of the terminal member 10 and the power electronic device 20 can be stably maintained.

[0151]

[0169] A plurality of fastening holes 160 may be formed. A plurality of fastening holes 160 may be arranged for each of a plurality of device receiving portions 150. In the illustrated embodiment, ten fastening holes 160 may be formed and arranged for each of the ten device receiving portions 150.

[0152]

[0198] The operating unit 230 receives an input of a control signal for controlling the operation of the power electronic device 20. The operating unit 230 is disposed on the other side of the first housing 210 opposite the second housing 220, i.e., on the front side in the illustrated embodiment. Therefore, an operator can easily approach the operating unit 230 and apply a control signal.

[0180]

[0199] The operating unit 230 communicates with and is electrically connected to the optional components and terminal member 240 housed in the internal space of the first housing 210 or the second housing 220 .

[0181]

[0200] The operation unit 230 may be configured in any form capable of receiving input of a control signal. In the illustrated embodiment, the operation unit 230 includes a plurality of buttons and a screen.

[0182]

[0201] The terminal member 240 is a part where the power electronic device 20 communicates with the terminal member 10 and electricity is passed through. The terminal member 240 is insertably coupled to the slot member 120 so as to be removable. This coupling allows the terminal member 240 and the slot member 120 to communicate with each other and be electrically connected.

[0183]

[0202] The terminal member 240 is disposed on one side of the second housing 220 facing the terminal member 10, that is, on the rear side in the illustrated embodiment. The terminal member 240 is exposed to the outside of the second housing 220.

[0184]

[0203] The terminal member 240 may be formed to correspond to the shape of the slot member 120. In the illustrated embodiment, the terminal member 240 is formed to extend in the height direction of the second housing 220, i.e., in the up-down direction.

[0185]

[0204] The fastening support 250 is a portion where the fastening member 260 is coupled to the second housing 220. The fastening support 250 is continuous with the second frame 221 and is disposed to partially surround the upper surface 222. In the illustrated embodiment, the fastening support 250 is located on the left side of the upper surface 222. The position of the fastening support 250 can be changed depending on the position of the fastening hole 160.

[0186]

[0205] The fastening support 250 may have any shape that can be coupled with the fastening member 260. In the illustrated embodiment, the fastening support 250 is formed to have a width in the left-right direction and a thickness in the front-rear direction.

[0187]

[0206] A space is formed inside the fastening support part 250, penetrating in the thickness direction, i.e., the front-rear direction, to which the fastening member 260 can be penetrated and coupled. In an embodiment in which the fastening member 260 is a screw member, a screw thread may be formed on the inner peripheral surface surrounding the space.

[0188]

[0207] The fastening member 260 connects the second housing 220 and the terminal member 10. As described above, the second housing 220 and the terminal member 10 are connected by the connecting member 400, and it can be said that the fastening member 260 additionally connects the second housing 220 and the terminal member 10. The fastening member 260 can stably maintain the connection between the second housing 220 and the terminal member 10.

[0189]

[0208] The fastening member 260 is coupled to the fastening support 250 and the fastening hole 160. Specifically, the fastening member 260 penetrates the space formed in the fastening support 250 and is inserted into the fastening hole 160. In one embodiment, the fastening member 260 may be screwed to the fastening support 250 and the fastening hole 160, respectively.

[0190]

[0209] The coupling member detachment portion 300 is a portion where the coupling member 400 is coupled to the housing 200, specifically, the second housing 220. The coupling member detachment portion 300 is formed on one side of the second housing 220, that is, on the upper rear side in the illustrated embodiment.

[0191]

[0210] The coupling member detachable portion 300 is partially surrounded by the second frame 221 and the top surface 222. In the illustrated embodiment, the front, left, and right sides of the coupling member detachable portion 300 are surrounded by the second frame 221, and the bottom side is surrounded by the top surface 222. The remaining sides of the coupling member detachable portion 300, that is, the top and rear sides in the illustrated embodiment, are open.

[0192]

[0211] The coupling member 400 can be coupled to or separated from the coupling member detachable portion 300 through the top side. Also, 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 detachable portion 300 can be formed integrally with the second housing 220.

[0193]

[0212] In the illustrated embodiment, the coupling member attaching / detaching portion 300 includes a coupling member receiving portion 310 , a coupling opening 320 and a member guide portion 330 .

[0194]

[0213] The coupling member accommodating portion 310 is a space that accommodates the coupling member 400. The coupling member accommodating portion 310 also accommodates other components of the coupling member attaching / detaching portion 300. The coupling member accommodating portion 310 is defined by being partially surrounded by the second frame 221 and the upper surface 222.

[0195]

[0214] The connecting member receiving portion 310 may be divided into a plurality of portions by the member guide portion 330. In the illustrated embodiment, the connecting member receiving portion 310 includes a first connecting member receiving portion 311 formed on the front side and a second connecting member receiving portion 312 formed on the rear side.

[0196]

[0215] The first connecting member receiving portion 311 receives a portion of the first connecting body 411 of the connecting member 400. The first connecting member receiving portion 311 is defined by being surrounded by the second frame 221, the upper surface 222, and the guide plates 331 and 332. The upper side of the first connecting member receiving portion 311 is open.

[0197]

[0216] The first coupling member accommodating portion 311 communicates with a space formed inside the second housing 220. Specifically, the first coupling member accommodating portion 311 communicates with the space through a first coupling opening 321 formed through a portion of the upper surface 222 surrounding the first coupling member accommodating portion 311.

[0198]

[0217] The second connecting member receiving portion 312 receives another part of the first connecting body 411 of the connecting member 400, the second connecting body 412, and the support arm 440. The second connecting member receiving portion 312 is defined by being surrounded by the second frame 221, the upper surface 222, and the guide plates 331 and 332. The upper and rear sides of the second connecting member receiving portion 312 are open.

[0199]

[0218] The second coupling member accommodating portion 312 communicates with a space formed inside the second housing 220. Specifically, the second coupling member accommodating portion 312 communicates with the space by a second coupling opening 322 formed through another portion of the top surface 222 surrounding the second coupling member accommodating portion 312.

[0200]

[0219] The second connecting member receiving portion 312 may be formed to have a volume that is relatively larger than that of the first connecting member receiving portion 311. As will be described later, this is because the volume of the other part of the first connecting body 411, the second connecting body 412, and the support arm 440 that are received in the second connecting member receiving portion 312 is larger than the volume of the part of the first connecting body 411 that is received in the first connecting member receiving portion 311.

[0201]

[0220] The coupling opening 320 is formed through the upper surface 222 to communicate the coupling member accommodating portion 310 with the internal space of the second housing 220. The coupling arm 420 of the coupling member 400 may pass through the coupling opening 320 and be partially accommodated in the internal space of the second housing 220.

[0202]

[0221] A plurality of coupling openings 320 may be formed. The plurality of coupling openings 320 may be formed in each of the plurality of coupling member receiving portions 310. In the illustrated embodiment, the coupling openings 320 include a first coupling opening 321 formed in the first coupling member receiving portion 311 and a second coupling opening 322 formed in the second coupling member receiving portion 312.

[0203]

[0222] A first connecting arm 421 is retractably connected to the first connecting opening 321. A second connecting arm 422 is retractably connected to the second connecting opening 322. Through this connection, the connecting arm 420 and the second housing 220 can be hook-connected.

[0204]

[0223] In the illustrated embodiment, the first and second coupling openings 321 and 322 are formed to have a rectangular cross section. The shapes of the first and second coupling openings 321 and 322 may vary depending on the shapes of the first and second coupling arms 421 and 422.

[0205]

[0224] The member guide part 330 guides the coupling member 400 so that the coupling member 400 is coupled to the coupling member detaching part 300 in a predetermined direction and position.

[0206]

[0225] The member guide portion 330 is located in the connecting member receiving portion 310. The member guide portion 330 divides the connecting member receiving portion 310 into a plurality of portions. In the illustrated embodiment, the member guide portion 330 is located biased toward the front side of the connecting member receiving portion 310 and divides the connecting member receiving portion 310 into a first connecting member receiving portion 311 and a second connecting member receiving portion 312.

[0207]

[0226] The member guide part 330 and the coupling member 400 may be coupled in a form in which one of them is movably inserted into the other. At this time, the member guide part 330 and the coupling member 400 may be movably inserted and coupled at a plurality of positions.

[0208]

[0227] In the illustrated embodiment, the member guide portion 330 includes a first guide plate 331 , a second guide plate 332 and a rib receiving portion 333 .

[0209]

[0228] The first guide plate 331 and the second guide plate 332 are formed to protrude from the upper surface 222. In the illustrated embodiment, the first guide plate 331 and the second guide plate 332 are formed to protrude upward.

[0210]

[0229] The first guide plate 331 is inserted into and coupled to the first guide groove 431a of the coupling member 400. The first guide plate 331 extends in the extension direction of the first guide groove 431a, which is the up-and-down direction in the illustrated embodiment. The first guide plate 331 is movably inserted into the first guide groove 431a to guide the coupling member 400 in ascending and descending directions.

[0211]

[0230] The second guide plate 332 is inserted into and coupled to the second guide groove 431b of the coupling member 400. The second guide plate 332 extends in the extension direction of the second guide groove 431b, which is the up-and-down direction in the illustrated embodiment. The second guide plate 332 is movably inserted into the second guide groove 431b to guide the coupling member 400 in ascending and descending directions.

[0212]

[0231] The first guide plate 331 and the second guide plate 332 are formed to extend in the width direction of the second housing 220, which is in the left-right direction in the illustrated embodiment. In this case, the extension length of each of the first guide plate 331 and the second guide plate 332 may be less than half the length of the connecting member receiving portion 310 in the width direction.

[0213]

[0232] Accordingly, the first guide plate 331 and the second guide plate 332 are arranged side by side with a predetermined space therebetween. In the illustrated embodiment, the first guide plate 331 is positioned on the left side, and the second guide plate 332 is positioned on the right side. Therefore, the left and right sides of the coupling member 400 are all guided and moved up and down to be coupled to or separated from the coupling member detachment part 300.

[0214]

[0233] The predetermined space formed between the first guide plate 331 and the second guide plate 332 is defined as a rib receiving portion 333 .

[0215]

[0234] The rib receiving portion 333 is a space that receives the guide rib 432 of the coupling member 400. The guide rib 432 can be inserted into the rib receiving portion 333 in a retractable manner.

[0216]

[0235] The rib receiving portion 333 is located between the first guide plate 331 and the second guide plate 332. The guide rib 432 received in the rib receiving portion 333 can be constrained on its left and right sides by the first guide plate 331 and the second guide plate 332.

[0217]

[0236] Therefore, the coupling member 400 coupled to the coupling member detachment unit 300 is allowed to move up and down, but is restricted from moving forward and backward or left and right, thereby enabling the coupled state of the coupling member 400 and the coupling member detachment unit 300 to be stably maintained.

[0218]

[0237] It will be understood that the positions and shapes of the first guide plate 331, the second guide plate 332 and the rib receiving portion 333 described above can be changed according to the position and shape of the guide portion 430 of the connecting member 400.

[0219]

[0238] 4. Description of the coupling member 400 according to the embodiment of the present invention

[0239] Referring again to FIG. 2, the power electronics 20 according to the embodiment of the present invention includes a coupling member 400 .

[0220]

[0240] The coupling member 400 is detachably coupled to the coupling member detaching portion 300 and the terminal member 10. In other words, the coupling member 400 detachably couples the power electronic device 20 and the terminal member 10.

[0221]

[0241] In the present specification, the description is given on the assumption 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.

[0222]

[0242] In the illustrated embodiment, a single coupling member 400 is provided. Alternatively, a plurality of coupling members 400 may be provided and releasably coupled to the coupling member detachable portion 300 and the terminal member 10 at a plurality of positions. It will be understood that a plurality of coupling member detachable portions 300 may also be provided in the above embodiment.

[0223]

[0243] In one embodiment, the connecting member 400 may be hook-coupled to the connecting member detachable portion 300 and the support member 140. Therefore, the connecting member 400 may be easily coupled to the connecting member detachable portion 300 and the support member 140, while maintaining a stable coupled state.

[0224]

[0244] Furthermore, the coupling member 400 according to the embodiment of the present invention can absorb vertical vibrations of the power electronic device 20 by its own structure without requiring a separate elastic member, thereby reducing manufacturing costs, improving manufacturing efficiency, and facilitating maintenance.

[0225]

[0245] Each component of the coupling member 400 described below may be integrally formed. Therefore, the process of separately manufacturing each component and coupling them together may be reduced, and the coupling between each component may be firmly maintained.

[0226]

[0246] In one embodiment, among the components of the connecting member 400 described below, the connecting arm 420 may be made of PC GF 10% (Polycarbonate Glass Fiber 10%) material, and the other components of the connecting member 400 may be made of PC-ABS (Polycarbonate / Acrylonitrile Butadiene Styrene) material.

[0227]

[0247] In this embodiment, the connecting arm 420 may have increased strength and tension compared to other configurations of the connecting member 400 .

[0228]

[0248] In the embodiment shown in FIGS. 9 to 15, the coupling member 400 includes a coupling body 410, a coupling arm 420, a guide portion 430, and a support arm 440.

[0229]

[0249] The connecting body 410 forms the body of the connecting member 400. The connecting body 410 is a portion of the connecting member 400 that is received in the connecting member detaching part 300. The connecting body 410 is continuous with some components of the connecting member 400. In addition, other components of the connecting member 400 are formed in the connecting body 410.

[0230]

[0250] In the illustrated embodiment, the coupling body 410 includes a first coupling body 411 , a second coupling body 412 , a pressure protrusion 413 , a pressure groove 414 , a plate receiving groove 415 and a coupling protrusion 416 .

[0231]

[0251] The first connecting body 411 forms a part of the connecting body 410, i.e., the front side in the illustrated embodiment. The first connecting body 411 is partially received in the first connecting member receiving portion 311 and the second connecting member receiving portion 312, respectively.

[0232]

[0252] The first connecting body 411 extends in a direction in which the connecting member 400 is connected to or separated from the connecting member detaching part 300, that is, in the vertical direction in the illustrated embodiment.

[0233]

[0253] The first connecting body 411 may have any shape that can be accommodated in the connecting member accommodating part 310 and coupled to the member guide part 330. In the illustrated embodiment, the first connecting body 411 has a polygonal pillar shape that has a height in the vertical direction and a width in the horizontal direction.

[0234]

[0254] The first connecting body 411 may be divided into a plurality of sections. In the illustrated embodiment, the first connecting body 411 includes a first section that forms a part of the front side and is received in the first connecting member receiving section 311, and a second section that forms a part of the rear side and is received in the second connecting member receiving section 312.

[0235]

[0255] Between the first and second parts, a guide groove 431 of a guide part 430 is positioned. In other words, the first connecting body 411 is divided into the first and second parts by the guide groove 431 positioned therein.

[0236]

[0256] Therefore, the first and second portions are disposed to face each other with the guide plates 331 and 332 inserted into the guide grooves 431 interposed therebetween.

[0237]

[0257] One side of the first portion of the first connecting body 411, which is the lower side in the illustrated embodiment, is continuous with the first connecting arm 421 of the connecting arm 420. The other side of the first connecting body 411, which is the upper side in the illustrated embodiment, is continuous with the pressure protrusion 413. The other side of the second portion of the first connecting body 411, which is the rear side in the illustrated embodiment, is continuous with the second connecting body 412.

[0238]

[0258] Furthermore, the other side of the second portion of the first connecting body 411, which is the rear side in the illustrated embodiment, is continuous with a support arm 440.

[0239]

[0259] The second connecting body 412 forms the other part of the connecting body 410, that is, the rear side in the illustrated embodiment. The second connecting body 412 is received in the second connecting member receiving portion 312.

[0240]

[0260] The second connecting body 412 is formed to extend in a direction in which the connecting member 400 is connected to or separated from the support member 140, that is, in the front-rear direction in the illustrated embodiment.

[0241]

[0261] One end of the second connecting body 412 in the extension direction that 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 extension direction that faces away from the first connecting body 411, i.e., the rear end in the illustrated embodiment, is continuous with the connecting protrusion 416.

[0242]

[0262] The second connecting body 412 is continuous with the second connecting arm 422. The second connecting body 412 supports the second connecting arm 422 from above.

[0243]

[0263] The second connecting body 412 may have any shape that can be received in the second connecting member receiving portion 312 and support the second connecting arm 422. In the illustrated embodiment, the second connecting body 412 is in the form of a plate that extends in the front-rear direction, has a width in the left-right direction, and has a thickness in the up-down direction.

[0244]

[0264] At this time, the width of the second combined body 412, that is, the length in the left-right direction, may be smaller than the width of the first combined body 411.

[0245]

[0265] The second connecting body 412 is surrounded by the support arms 440. That is, as will be described later, the second connecting body 412 is disposed between the pair of support arms 440 so as to be spaced apart from each of the support arms 441 and 442.

[0246]

[0266] The pressure protrusion 413 is formed to protrude from the upper side of the first connecting body 411. An operator can connect the connecting member 400 to the connecting member detachment part 300 by applying pressure to the pressure protrusion 413. As described above, in an embodiment in which the connecting member 400 and the connecting member detachment part 300 are hook-coupled, an external force for hook coupling can be applied to the pressure protrusion 413.

[0247]

[0267] Furthermore, when the power electronic device 20 is connected to the terminal member 10, the pressure protrusion 413 protrudes outward. An operator can apply pressure to the pressure protrusion 413 to release the connection between the support member 140 and the connecting arm 420, and then separate the power electronic device 20 from the terminal member 10.

[0248]

[0268] The pressing protrusion 413 is continuous with the first connecting body 411. In the illustrated embodiment, the front lower side of the pressing protrusion 413 is continuous with the first portion of the first connecting body 411, and the rear lower side of the pressing protrusion 413 is continuous with the second portion of the first connecting body 411. The pressing protrusion 413 is disposed to cover the guide portion 430 located between the first portion and the second portion of the first connecting body 411 from above.

[0249]

[0269] The pressing protrusion 413 may be formed to have the same width and length as the first connecting body 411. A lightening groove 413a may be recessed and formed on the upper side of the pressing protrusion 413, thereby improving the ease of processing the pressing protrusion 413. In addition, the lightening groove 413a increases the frictional force on the upper side of the pressing protrusion 413, thereby facilitating the process of connecting the connecting member 400 and the connecting member detachment part 300 and the process of separating the power electronic device 20 and the terminal member 10.

[0250]

[0270] The pressure groove 414 is recessed into the coupling protrusion 416. When attempting to separate the coupling member 400 from the coupling member detachment part 300, the coupling protrusion 416 is pressed in a direction toward the first coupling body 411, i.e., forward in the illustrated embodiment. At this time, the formation of the pressure groove 414 increases the frictional force generated on the surface of the coupling protrusion 416, thereby reducing the amount of external force that the operator must apply.

[0251]

[0271] That is, the pressure groove 414 increases the frictional force of the coupling protrusion 416, making it easier for the operator to grip and apply pressure to the coupling protrusion 416.

[0252]

[0272] The pressure groove 414 is recessed into one surface of the coupling protrusion 416 that faces away from the first coupling body 411, i.e., the rear side in the illustrated embodiment. As will be described later, this surface is defined as a second support surface 416b.

[0253]

[0273] The plate receiving groove 415 is a space formed inside the first combined body 411. The first guide plate 331 and the second guide plate 332 of the member guide part 330 are received in the plate receiving groove 415 so as to be retractable.

[0254]

[0274] The plate receiving groove 415 is partially surrounded by the first connecting body 411 and the pressing protrusion 413. In the illustrated embodiment, the front side of the plate receiving groove 415 is surrounded by the first part of the first connecting body 411, and the rear side of the plate receiving groove 415 is surrounded by the second part of the first connecting body 411. The upper side of the plate receiving groove 415 is covered by the pressing protrusion 413.

[0255]

[0275] The bottom of the plate receiving groove 415 is open so that the first guide plate 331 and the second guide plate 332 can be retractably received therein. The outer sides of the width direction of the plate receiving groove 415, i.e., the left and right sides in the illustrated embodiment, are connected to the outside by the first guide groove 431a and the second guide groove 431b.

[0256]

[0276] Therefore, it will be understood that the guide plates 331 and 332 accommodated in the plate accommodating groove 415 are also movably inserted into the guide grooves (431a and 431b), respectively.

[0257]

[0277] A guide rib 432 is positioned 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, 332.

[0258]

[0278] The coupling protrusion 416 is a portion where the coupling member 400 is coupled to the support member 140 of the terminal member 10. The coupling protrusion 416 can be hook-coupled to the second extension arm 142 of the support member 140.

[0259]

[0279] The coupling protrusion 416 is continuous with the second coupling body 412. Specifically, the coupling protrusion 416 is continuous with the other end of the second coupling body 412 in the extension direction opposite to the first coupling body 411, i.e., the rear end in the illustrated embodiment.

[0260]

[0280] The coupling protrusion 416 may be formed to protrude upward from the second coupling body 412. Due to the protrusion, the coupling protrusion 416 may be hook-coupled to the second extension arm 142. In the illustrated embodiment, the coupling protrusion 416 is formed to protrude upward from the second coupling body 412.

[0261]

[0281] The coupling protrusion 416 may be formed to have a width that is the same length as the second coupling body 412. In other words, the coupling protrusion 416 is formed to have a width that is shorter than the width of the first coupling body 411. Accordingly, the coupling protrusion 416 is disposed between the plurality of support arms 440 and spaced apart from the support arms 440.

[0262]

[0282] The coupling protrusion 416 may include a plurality of surfaces, which may be contiguous with each other at a predetermined angle. In the illustrated embodiment, the coupling protrusion 416 includes a first support surface 416a and a second support surface 416b.

[0263]

[0283] The first support surface 416a is a surface of the coupling protrusion 416 facing the first coupling body 411, which forms the front side in the illustrated embodiment. The first support surface 416a is continuous with the second coupling body 412.

[0264]

[0284] The first supporting surface 416a extends at a predetermined angle with the second connecting body 412. In the illustrated embodiment, the first supporting surface 416a forms an obtuse angle with the upper surface of the second connecting body 412 and extends in a slanted direction opposite to the first connecting body 411. In other words, the first supporting surface 416a extends in a slanted direction toward the lower front side and the upper rear side.

[0265]

[0285] When the coupling member 400 is coupled to the support member 140, the first support surface 416a comes into contact with the fifth extension surface 142e of the second extension arm 142. That is, the first support surface 416a comes into contact with and is supported by the fifth extension surface 142e. For this reason, the first support surface 416a and the fifth extension surface 142e may be extended to have the same inclination.

[0266]

[0286] The first support surface 416a is continuous with the second support surface 416b via the upper surface of the coupling protrusion 416.

[0267]

[0287] The second support surface 416b forms the other surface of the coupling protrusion 416 opposite to the first coupling body 411, ie, the rear side surface in the illustrated embodiment. The second support surface 416b is continuous with the first support surface 416b.

[0268]

[0288] The second support surface 416b extends at a predetermined angle with the upper surface of the coupling protrusion 416. In the illustrated embodiment, the second support surface 416b extends at an obtuse angle with the upper surface of the coupling protrusion 416, sloping in the opposite direction to the first coupling body 411. In other words, the second support surface 416b extends at an angle toward the upper front side and the lower rear side.

[0269]

[0289] When the coupling member 400 moves toward the support member 140, the second support surface 416b comes into contact with the third extension surface 142c of the second extension arm 142. As the coupling member 400 continues to move, the second extension arm 142 rides on the second support surface 416b and moves toward the upper side of the coupling protrusion 416, and enters the space between the first support surface 416a and the first coupling body 411. Accordingly, the coupling member 400 and the support member 140 may be hook-coupled.

[0270]

[0290] For this purpose, the second support surface 416b and the third extension surface 142c may be formed to have the same inclination.

[0271]

[0291] The coupling arm 420 is a portion where the coupling member 400 is coupled to the coupling member detachable part 300. The coupling arm 420 may be detachably coupled to the coupling member detachable part 300. Accordingly, the coupling member 400 and the housing 200 may be hook-coupled.

[0272]

[0292] The connecting arm 420 is continuous with the connecting body 410. The connecting arm 420 is continuous with one of the sides of the connecting body 410 facing the connecting member detaching part 300, that is, the lower end in the illustrated embodiment.

[0273]

[0293] There may be a plurality of connecting arms 420. The connecting arms 420 are connected to the first connecting body 411 and the second connecting body 412, respectively, and are connected to the connecting openings 320, respectively.

[0274]

[0294] In the illustrated embodiment, the connecting arm 420 includes a first connecting arm 421 and a second connecting arm 422 .

[0275]

[0295] The first connecting arm 421 is continuous with the first connecting body 411 and is connected to the first connecting opening 321. The first connecting arm 421 is detachably connected to the inner upper surface of the second housing 220 at the outer periphery of the first connecting opening 321.

[0276]

[0296] The first connecting arm 421 is continuous with the lower end of the first portion, i.e., the front portion, of the first connecting body 411. The first connecting arm 421 is formed to extend in the height direction of the first connecting body 411, that is, in the vertical direction in the illustrated embodiment.

[0277]

[0297] The first connecting arm 421 may be formed to have a width shorter than the width of the first connecting body 411. Also, the first connecting arm 421 may be formed to be equal to or shorter than the length of the first connecting opening 321 in the width direction, i.e., the left-right direction.

[0278]

[0298] In the illustrated embodiment, the first coupling arm 421 includes a first coupling extension 421a and a first coupling protrusion 421b.

[0279]

[0299] The first coupling extension 421a is a portion where the first coupling arm 421 is connected to the first coupling body 411. The first coupling extension 421a passes through the first coupling opening 321.

[0280]

[0300] The first coupling extension 421a extends downward from the lower end of the first coupling body 411. One end of the first coupling extension 421a in the extension direction, which is the upper end in the illustrated embodiment, is continuous with the first portion of the first coupling body 411. A first coupling protrusion 421b is located at the other end of the first coupling extension 421a in the extension direction, which is the lower end in the illustrated embodiment.

[0281]

[0301] The first coupling protrusion 421b is a portion where the first coupling arm 421 is hook-coupled to the coupling member detaching part 300. The first coupling protrusion 421b is formed on the other end of the first coupling extension part 421a, that is, on the lower end in the illustrated embodiment.

[0282]

[0302] The first coupling protrusion 421b protrudes outward from the first coupling extension 421a. In the illustrated embodiment, the first coupling protrusion 421b protrudes forward. The first coupling protrusion 421b includes a first portion extending horizontally and a second portion connected to the first portion and extending downwardly toward the first coupling extension 421b.

[0283]

[0303] The first connecting arm 421 may be pressed inward, or rearward in the illustrated embodiment, and may pass through the first connecting opening 321. At this time, the first portion may contact the outer periphery of the first connecting opening 321 and be pressed rearward.

[0284]

[0304] When the first coupling protrusion 421b is completely inserted into the first coupling opening 321, the pressure is released and the first coupling arm 421 can move forward. At this time, the second portion comes into contact with the surface of the outer periphery of the first coupling opening 321 that is positioned inside the second housing 220. Accordingly, the hook coupling between the first coupling arm 421 and the coupling member attaching / detaching part 300 is completed.

[0285]

[0305] The second connecting arm 422 is continuous with the second connecting body 412 and is connected to the second connecting opening 322. The second connecting arm 422 is detachably connected to the inner upper surface of the second housing 220 at the outer periphery of the second connecting opening 322.

[0286]

[0306] 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 in the height direction of the second connecting body 412, ie, in the vertical direction in the illustrated embodiment.

[0287]

[0307] The second connecting arm 422 may be formed to have a width shorter than the width of the second connecting body 412. In the illustrated embodiment, the second connecting arm 422 may be formed to be equal to or shorter than the length of the second connecting opening 322 in the width direction, i.e., the left-right direction.

[0288]

[0308] In the illustrated embodiment, the second coupling arm 422 includes a second coupling extension 422a and a second coupling protrusion 422b.

[0289]

[0309] The second coupling extension 422a is a portion where the second coupling arm 422 is connected to the second coupling body 412. The second coupling extension 422a passes through the second coupling opening 322.

[0290]

[0310] The second coupling extension 422a extends downward from the lower end of the second coupling body 412. One end of the second coupling extension 422a in the extension direction, which is the upper end in the illustrated embodiment, is continuous with the second coupling body 412. A second coupling protrusion 422b is located at the other end of the second coupling extension 422a in the extension direction, which is the lower end in the illustrated embodiment.

[0291]

[0311] The second coupling protrusion 422b is a portion where the second coupling arm 422 is hook-coupled to the coupling member detachment part 300. The second coupling protrusion 422b is formed on the other end of the second coupling extension part 422a, that is, on the lower end in the illustrated embodiment.

[0292]

[0312] The second coupling protrusion 422b protrudes outward from the second coupling extension 422a. In the illustrated embodiment, the second coupling protrusion 422b protrudes rearward. The second coupling protrusion 422b includes a first portion extending horizontally and a second portion that is continuous with the first portion and extends inclined downward toward the second coupling extension 422a.

[0293]

[0313] The second connecting arm 422 may be pressed inward, or forward in the illustrated embodiment, and may pass through the second connecting opening 322. At this time, the second portion may contact the outer periphery of the second connecting opening 322 and be pressed forward.

[0294]

[0314] When the second coupling protrusion 422b is completely inserted into the second coupling opening 322, the pressure is released and the second coupling arm 422 can move forward. At this time, the second portion comes into contact with the surface of the outer periphery of the second coupling opening 322 that is positioned inside the second housing 220. Accordingly, the hook coupling between the second coupling arm 422 and the coupling member attaching / detaching part 300 is completed.

[0295]

[0315] Therefore, the coupling member 400 can be hook-coupled to the coupling member detachment part 300 by a plurality of coupling arms 420. At this time, due to the shape of the coupling protrusions 421b and 422b, an operator can couple the coupling member 400 and the coupling member detachment part 300 by simply pressing the coupling member 400 against the coupling member detachment part 300.

[0296]

[0316] In addition, the shapes of the coupling protrusions 421b and 422b form a hook coupling between the coupling member 400 and the coupling member detachment unit 300. Therefore, unless an external force is applied in a predetermined direction, the coupled state between the coupling member 400 and the coupling member detachment unit 300 can be stably maintained.

[0297]

[0317] In addition, the first connecting arm 421 and the second connecting arm 422 may be formed symmetrically in the front-rear direction. Accordingly, the workability of the connecting member 400 may be improved. Also, the connecting member 400 and the housing 200 may be easily connected and separated. Furthermore, the connecting member 400 connected to the housing 200 will not swing in any direction, particularly in the front-rear direction in which the first connecting arm 421 and the second connecting arm 422 are spaced apart.

[0298]

[0318] The guide portion 430 guides the coupling member 400 so that the coupling member 400 is coupled to the coupling member detachment portion 300 in a predetermined direction. The guide portion 430 is movably coupled to the member guide portion 330 of the coupling member detachment portion 300. The coupling member 400 and the coupling member detachment portion 300 can be coupled to or separated from each other while the guide portion 430 and the member guide portion 330 are coupled to each other.

[0299]

[0319] The guide part 430 is continuous with the coupling body 410. Specifically, the guide part 430 is located on one side of the coupling body 410 facing the coupling member detachment part 300, i.e., the lower side in the illustrated embodiment. The guide part 430 is located between the first part (i.e., the front part) and the second part (i.e., the rear part) of the first coupling body 411.

[0300]

[0320] In the illustrated embodiment, the guide portion 430 includes a guide groove 431 and a guide rib 432 .

[0301]

[0321] The guide groove 431 is a space into which the guide plates 331 and 332 of the member guide part 330 are movably inserted. The guide groove 431 is formed to extend in the extension direction of the guide plates 331 and 332, that is, in the vertical direction in the illustrated embodiment.

[0302]

[0322] The guide grooves 431 are formed in the first combined body 411. In the illustrated embodiment, the guide grooves 431 are formed in the width direction, i.e., on the left and right sides, of the first combined body 411. The guide grooves 431 are formed to penetrate the left and right sides of the first combined body 411.

[0303]

[0323] The guide groove 431 communicates with the plate receiving groove 415. A portion of the guide plates 331 and 332 is received in the plate receiving groove 415, and the other portion of the guide plates 331 and 332 can be movably inserted into the guide groove 431.

[0304]

[0324] The guide groove 431 may be formed to have a length greater than or equal to the thickness of the guide plates 331 and 332, that is, the length in the front-rear direction in the illustrated embodiment.

[0305]

[0325] There may be a plurality of guide grooves 431. The plurality of guide grooves 431 are formed at different positions of the first connecting body 411 to movably accommodate different guide plates 331 and 332.

[0306]

[0326] In the illustrated embodiment, the guide groove 431 includes a first guide groove 431a and a second guide groove 431b.

[0307]

[0327] The first guide groove 431a is formed through the left side of the first combined body 411. The first guide plate 331 is movably inserted and combined into the first guide groove 431a.

[0308]

[0328] The second guide groove 431b is formed through the right side of the first connecting body 411. The second guide plate 332 is movably inserted and connected to the second guide groove 431b.

[0309]

[0329] Guide ribs 432 are formed on both sides of the first guide groove 431a and the second guide groove 431b.

[0310]

[0330] 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 extension direction of the guide plates 331 and 332, that is, in the vertical direction in the illustrated embodiment.

[0311]

[0331] The guide rib 432 is continuous with the first connecting body 411. In the illustrated embodiment, the guide rib 432 is formed to protrude forward from the front side of the second portion of the first connecting body 411.

[0312]

[0332] The guide rib 432 may extend to a height shorter than the height of the first connecting body 411. In this case, one end of the guide rib 432 in its extension 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 connecting body 411.

[0313]

[0333] Therefore, the second portion of the first coupling body 411 and the guide rib 432 may be placed together on a portion of the upper surface 222 surrounding the second coupling opening 322. Accordingly, even when the power electronic device 20 vibrates in the vertical direction, the coupled state of the coupling member 400 and the coupling member detachment part 300 may be stably maintained.

[0314]

[0334] The guide rib 432 may be formed to have a thickness equal to or smaller than the width of the rib receiving portion 333. Accordingly, the guide rib 432 may be easily inserted into and pulled out from the rib receiving portion 333.

[0315]

[0335] The support arm 440 provides a restoring force to the connecting member 400. When vertical vibration occurs in the connecting member 400 and the power electronic device 20 connected to the connecting member 400, the support arm 440 is deformed to store a restoring force, thereby absorbing the impact caused by the generated vibration.

[0316]

[0336] Accordingly, even if the coupling member 400 does not include a separate elastic member such as a spring, the coupling state between the power electronic device 20 and the terminal member 10 can be stably maintained.

[0317]

[0337] When the coupling member 400 is coupled to the coupling member detachment part 300, the support arm 440 extends downward 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 upper surface 222, and the coupling body 410 is spaced apart from the upper surface 222.

[0318]

[0338] In the above state, if vertical vibration occurs, the support arm 440 may deform, the coupling member 400 may descend, and the coupling body 410 may come into contact with the upper surface 222. Furthermore, when the vibration is released, the support arm 440 may be restored by the elastic force stored in the deformed shape, and the coupling body 410 may be separated from the upper surface 222 again.

[0319]

[0339] Therefore, even if vertical vibrations occur in the terminal member 10 and the power electronic device 20 coupled thereto, the vibrations can be buffered by the support arm 440. As a result, damage to the terminal member 10 and the power electronic device 20 can be prevented. Furthermore, damage to the coupling member 400 coupled to the terminal member 10 and the power electronic device 20, respectively, can be prevented.

[0320]

[0340] The support arm 440 is continuous with the combined body 410. Specifically, the support arm 440 is continuous with the second portion (i.e., rear portion) of the first combined body 411. The support arm 440 extends from the rear side of the second portion of the first combined body 411 in an inclined manner toward the rear lower side.

[0321]

[0341] One end of the support arm 440 in the extension direction, which is the front upper end 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 extension direction, which is the rear lower end in the illustrated embodiment, is located lower than the lower ends of the first connecting body 411 and the second connecting body 412. With this structure, the support arm 440 can elastically support the connecting member 400.

[0322]

[0342] The support arm 440 is disposed to be spaced apart from the second connecting body 412 and the connecting protrusion 416. The support arm 440 partially surrounds the second connecting body 412 and the connecting protrusion 416 on the outer side in the width direction.

[0323]

[0343] A plurality of support arms 440 may be provided. The plurality of support arms 440 may be connected to the connecting body 410 at different positions and contact the upper surface 222 at different positions to elastically support the connecting member 400. In the illustrated embodiment, two support arms 440 are provided, including a first support arm 441 and a second support arm 442.

[0324]

[0344] The first support arm 441 and the second support arm 442 are spaced apart from each other and are disposed to face each other across the second connecting body 412 and the connecting protrusion 416. In one embodiment, the first support arm 441 and the second support arm 442 may extend to the same length.

[0325]

[0345] The first support arm 441 is continuous with the left portion of the first connecting body 411 behind the second portion. The first support arm 441 extends obliquely downward, surrounding the second connecting body 412 and the connecting protrusion 416 on the left side. The lower end of the first support arm 441 may be located lower than the lower end of the connecting body 410.

[0326]

[0346] The second support arm 442 is continuous with the right portion behind the second portion of the first connecting body 411. The second support arm 442 extends obliquely downward, surrounding the second connecting body 412 and the connecting protrusion 416 on the right side. The lower end of the second support arm 442 may be located lower than the lower end of the connecting body 410.

[0327]

[0347] 5. Description of the process of connecting the terminal member 10 and the power electronic device 20 according to the embodiment of the present invention

[0348] The power electronic device 20 according to the embodiment of the present invention includes a coupling member 400. The coupling member 400 is detachably coupled to the coupling member detachable portion 300 of the power electronic device 20. Accordingly, the coupling member 400 is also detachably coupled to the support member 140 of the terminal member 10. In one embodiment, the coupling member 400 may be hook-coupled to the coupling member detachable portion 300 and the support member 140, respectively.

[0328]

[0349] In the case of the power electronic device according to the prior art, the power electronic device is directly connected to the terminal member through a structure integral with the power electronic device itself, so if the structure is damaged, the entire cover of the power electronic device must be replaced.

[0329]

[0350] In addition, in conventional power electronic devices, various devices housed inside are generally integrated with the cover, which poses a problem that the devices inside must also be disassembled when replacing the cover.

[0330]

[0351] Therefore, excessive time and cost are required to maintain and repair the components connecting the power electronic device and the terminal member, and there is also a risk of unintended damage to the electrical components during the disassembly process for electrical components that do not require maintenance.

[0331]

[0352] On the other hand, when the coupling member 400 according to the embodiment of the present invention is damaged, maintenance work can be completed by replacing only the coupling member 400. Therefore, not only is the time and cost required for maintenance reduced, but the connection state of sensitive electrical components is not damaged, and the service life and operational reliability of the power electronic device 20 can be improved.

[0332]

[0353] Furthermore, the coupling member 400 is elastically supported by the support arm 440. Therefore, vibrations generated by the operation of the power electronic device 20 and the terminal member 10 can be buffered by the coupling member 400. Accordingly, damage to the structure of the power electronic device 20 due to the vibrations can be prevented. Furthermore, since there is no need to provide a separate elastic member for buffering vibrations, assembly can be improved and manufacturing costs can be reduced.

[0333]

[0354] Hereinafter, the process of coupling the power electronic device 20 and the terminal member 10 according to the embodiment of the present invention and the coupled state will be described in detail with reference to FIGS.

[0334]

[0355] (1) 1. Description of a coupling process between the power electronic device 20 and the coupling member 400 according to an embodiment of the present invention

[0356] 16 to 20, a process of coupling a coupling member 400 to a coupling member detaching unit 300 of a power electronic device 20 according to an embodiment of the present invention and a coupled state are shown.

[0335]

[0357] 16, the coupling member 400 is moved from the top to the bottom to be coupled to the coupling member detaching part 300. As described above, the front, left and right sides of the coupling member detaching part 300 are surrounded by the second frame 221, and the bottom side is surrounded by the top surface 222, but the top and rear sides are open. The coupling member 400 is coupled to the coupling member detaching part 300 through the top side.

[0336]

[0358] Referring to FIG. 17, a process of coupling the coupling member 400 to the coupling member detaching part 300 is illustrated.

[0337]

[0359] 17(a), the coupling member 400 is positioned above the coupling member detachment part 300. At this time, the first coupling arm 421 is positioned above the first coupling opening 321, and the second coupling arm 422 is positioned above the second coupling opening 322.

[0338]

[0360] 17(b), the second coupling arm 422 is inserted first into the second coupling opening 322. In the illustrated embodiment, the coupling member 400 is rotated clockwise so that the rear second coupling arm 422 is inserted first into the rear second coupling opening 322.

[0339]

[0361] 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 counterclockwise so that the front first coupling arm 421 is inserted into the front first coupling opening 321.

[0340]

[0362] At this time, the member guide part 330 and the guide part 430 are also movably coupled to each other, so that accurate coupling of the coupling member 400 and the coupling member detaching part 300 can be guided.

[0341]

[0363] 18 to 20, a state in which the coupling member 400 is coupled to the coupling member detaching portion 300 is shown.

[0342]

[0364] First, the first coupling arm 421 passes through the first coupling opening 321, and the first coupling protrusion 421b is hooked to the front side of the upper inner surface of the second housing 220. Similarly, the second coupling arm 422 passes through the second coupling opening 322, and the second coupling protrusion 422b is hooked to the rear side of the upper inner surface of the second housing 220.

[0343]

[0365] Therefore, the coupling member 400 and the coupling member detaching portion 300 can be prevented from being separated arbitrarily.

[0344]

[0366] 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 so as to be movable up and down, respectively. Also, the guide rib 432 is inserted into the rib accommodating portion 333 so as to be movable up and down.

[0345]

[0367] Therefore, the movement of the connecting member 400 in the front-rear and left-right directions is restricted by the connection between the member guide portion 330 and the guide portion 430 .

[0346]

[0368] At this time, the coupling member 400 is elastically supported by the support arm 440 that contacts the upper surface 222. That is, the remaining components of the coupling member 400 except for the lower end of the support arm 440 are spaced apart from the upper surface 222.

[0347]

[0369] Therefore, even if vibration occurs in the power electronic device 20, the elastic force applied by the support arm 440 can mitigate the impact of the vibration.

[0348]

[0370] (2) Description of the process of connecting the terminal member 10 and the power electronic device 20 according to the embodiment of the present invention

[0371] 21 to 23, there are shown a process of coupling a power electronic device 20 and a terminal member 10 according to an embodiment of the present invention, and a coupled state thereof. It will be understood that in the illustrated embodiment, a coupling member 400 is detachably coupled to the power electronic device 20.

[0349]

[0372] 21, the power electronic device 20 is moved from the front side to the rear side to be coupled with the terminal member 10. At this time, the protrusions (not shown) formed on the lower side of the second housing 220 are arranged to overlap with the base grooves 131, the terminal member 240 with the slot member 120, the fastening support portion 250 with the fastening hole 160, and the coupling member 400 with the support member 140 in the front-rear direction.

[0350]

[0373] 22, the procedure for coupling the power electronics 20 to the terminal member 10 is illustrated. In the illustrated embodiment, the power electronics 20 is rotated counterclockwise so that the protrusion (not shown) formed on the underside of the second housing 220 is inserted into the base groove 131 first. TIFF2025528057000002.tif9170

[0351]

[0374] Next, the power electronics 20 is rotated clockwise to couple the terminal member 240 with the slot member 120 and couple the coupling member 400 with the support member 140 . Although not shown, a process of coupling the fastening member 260 to the fastening support 250 and the fastening hole 160 may be further performed.

[0352]

[0375] Referring to FIG. 23, the power electronics 20 is shown coupled to the terminal member 10.

[0353]

[0376] The coupling protrusion 416 presses the second extension arm 142 upward and moves rearward. At this time, the third extension surface 142c comes into contact with the second support surface 416b and moves upward on the second support surface 416b.

[0354]

[0377] When 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.

[0355]

[0378] In this state, the support member 140 presses the coupling member 400 downward due to its shape, and the coupling member 400 is pressed upward by the elastic force applied by the support arm 440. As a result, the power electronic device 20 and the terminal member 10 can be stably hook-coupled.

[0356]

[0379] In this state, when attempting to separate the power electronic device 20 from the terminal member 10, applying pressure to the pressure protrusion 413 compresses the support arm 440, causing the coupling member 400 to move downward. Accordingly, when the support member 140 and the coupling member 400 are separated, the power electronic device 20 moves forward and can be separated from the terminal member 10.
