Description

[Technical field]

[0001] The present invention relates to an operation panel for a power converter and a power converter, and more particularly to an operation panel for a power converter provided with an operation unit for operating a main body of the power converter, and a power converter. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known an operation panel for a power converter provided with an operation unit (switch) for performing operations on a main body of the power converter (see, for example, Patent Document 1).

[0003] The above-mentioned Patent Document 1 discloses an operation panel for a power conversion device that includes a switch for selecting an operating method of the power conversion device main body, a switch for selecting an output frequency setting of the power conversion device main body, and a connector for connecting to the power conversion device main body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2005-117733 A Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, the number of functions required for a power conversion device operation panel has been increasing, and the functions required for the operation panel include being able to communicate with external devices, as well as being able to operate even when the power supply from the power conversion device main body is cut off. Therefore, there is a demand for an operation panel that is equipped with a button battery as an auxiliary power source for the operation panel when the power supply is cut off, and that allows the button battery to be replaced.

[0006] However, in the conventional power conversion device operation panel described in the above Patent Document 1, an operation unit (switch) for operating the power conversion device main body is provided on the operation panel, so if a button battery is replaceably mounted on the operation unit side as an auxiliary power source, the space on the operation unit side becomes narrow, making it impossible to provide a communication connector for communicating with external devices on the operation unit side. In addition, since the size of the operation panel main body is determined by the main body of the power conversion device to which the operation panel is connected, the size of the operation panel main body cannot be easily changed, so it is difficult to increase the size of the printed circuit board to mount a communication connector, etc. As a result, there is a demand for a power conversion device operation panel and a power conversion device that can suppress the narrowing of the space on the operation unit side while replaceably mounting a button battery for supplying power to the operation panel.

[0007] The present invention has been made to solve the problems described above, and one object of the present invention is to provide an operation panel for a power conversion device and a power conversion device that can accommodate a replaceable button battery for supplying power to the operation panel while preventing the space on the operation unit side from becoming narrower. [Means for solving the problem]

[0008] In order to achieve the above object, a power conversion device operation panel according to a first aspect of the present invention includes an operation panel board having an operation unit on a front side thereof for performing operations on a power conversion device main body, a first terminal and a second terminal provided on a back side of the operation panel board corresponding to a button battery for supplying power to the operation panel board, a battery positioning unit for positioning the button battery with respect to the first terminal and the second terminal, and an opening provided so as to expose the battery positioning unit, the back cover being disposed so as to cover the back side of the operation panel board, and a battery cover configured to be attachable to and detachable from the back cover and provided so as to cover the opening. a card slot portion provided on the rear surface of the operation panel board for inserting a memory card; Equipped with The card slot is configured so that the memory card is removed from the battery positioning portion. .

[0009] In the power converter operation panel according to the first aspect, as described above, an operation unit for operating the power converter main body is provided on the front side of the operation panel substrate. The first and second terminals are provided on the rear side of the operation panel substrate in correspondence with the button battery. This allows the button battery to be mounted on the rear side of the operation panel substrate on which the first and second terminals are provided, and therefore, unlike the case where the button battery is mounted on the front side of the operation panel substrate on which the operation unit is provided, it is possible to prevent the space on the operation unit side of the operation panel from becoming narrow. In addition, the battery cover configured to be attachable and detachable to the rear cover covers the opening provided so that the battery positioning unit is exposed, and thus the user can attach and detach the button battery (replace the button battery) from the battery positioning unit that positions the button battery by removing the battery cover. As a result, it is possible to prevent the space on the operation unit side from becoming narrow while mounting a button battery for supplying power to the operation panel in an exchangeable manner.

[0010] In the power converter operation panel according to the first aspect, the operation panel body is preferably detachably attached to the power converter body. With this configuration, even when the rear side of the operation panel body is attached to the power converter body, it is possible to easily attach and detach a button battery (replace the button battery) to and from the first terminal and the second terminal provided on the rear surface of the operation panel substrate by removing the operation panel body from the power converter body.

[0011] In the power conversion device operation panel according to the first aspect, preferably , MisaoThe operation panel substrate is provided with a stroke area for sliding the memory card to insert it into the card slot and remove it from the card slot, and the opening is provided in the back cover so that the battery positioning portion and the stroke area are exposed. Here, as a function required for the operation panel for the power conversion device, it is required that a memory card for storing communication settings and communication logs with an external device (device) can be mounted. With the above configuration, since the back side of the operation panel substrate is provided with a card slot portion for inserting a memory card, the back side of the operation panel substrate can be provided with a memory card, and communication settings and communication logs with an external device (device) of the power conversion device can be stored in the memory card. Furthermore, if the operation panel substrate is configured to have a stroke area for sliding the memory card to insert it into the card slot and remove it from the card slot, as described above, the memory card can be easily inserted into the card slot and removed from the card slot. Furthermore, if the back cover is configured to have an opening so that the battery positioning portion and the stroke area are exposed, a battery cover that is provided to cover the opening can be provided in common for the battery positioning portion and the stroke area. As a result, an increase in the number of parts and a complicated device configuration can be suppressed.

[0012] In the configuration including the card slot, the stroke area is preferably provided between the card slot and the battery positioning area. This configuration allows the battery positioning area and the stroke area to be closer to each other, unlike the case where the stroke area is provided on the opposite side of the card slot from the side where the battery positioning area is located. Therefore, the opening where the battery positioning area and the stroke area are exposed can be made smaller. As a result, it is possible to prevent foreign matter from entering the operation panel when a user removes a battery cover provided to cover the opening to perform work.

[0013] In the configuration with the card slot, the battery positioning part is preferably configured to be able to flex and deform when the button battery is installed and removed, and the back cover further includes a deflection restricting part that restricts the amount of deflection of the battery positioning part when the button battery is installed and removed. With this configuration, the amount of deflection of the battery positioning part can be restricted by the deflection restricting part, so that damage to the battery positioning part due to excessive deflection can be suppressed when installing and removing the button battery (replacing the button battery).

[0014] In the configuration in which the stroke region is provided between the card slot section and the battery positioning section, the battery positioning section is preferably provided along the outer peripheral surface of the button battery and includes a snap-fit ​​section that is flexible and deformable when the button battery is attached and detached, and the snap-fit ​​section is provided with a positioning protrusion that protrudes toward the side where the button battery is placed and the side where the second terminal is placed in order to position the button battery relative to the second terminal. With this configuration, the snap-fit ​​section is flexible and deformable when the button battery is attached and detached, making it easy to attach and detach the button battery (replace the button battery). In addition, by providing the snap-fit ​​section that is provided along the outer peripheral surface of the button battery with a positioning protrusion that protrudes toward the side where the button battery is placed and the side where the second terminal is placed, the button battery attached to the snap-fit ​​section can be pressed toward the second terminal. As a result, the button battery and the second terminal can be reliably contacted when the button battery is attached.

[0015] In the configuration in which the battery positioning portion includes a snap-fit ​​portion, the snap-fit ​​portion includes a pair of elastically deformable arc-shaped arms that are provided in an arc shape along the outer circumferential surface of the button battery, and the tips of the pair of arc-shaped arms are provided on the side where the stroke region is located relative to the button battery. With this configuration, when removing the button battery, the user can easily push apart the pair of elastically deformable arc-shaped arms of the snap-fit ​​portion from the stroke region side. As a result, the button battery can be easily removed.

[0016] In this case, the first terminal is preferably arranged in the area surrounded by the pair of arc-shaped arms closer to the tip of the pair of arc-shaped arms than the center of the position where the button battery is arranged. Here, the button battery has a negative pole on one side and a positive pole on the other side, and also has a positive pole on the outer circumferential surface of the button battery. Therefore, when the button battery is inserted at an angle from the tip of the pair of arc-shaped arms into the area surrounded by the pair of arc-shaped arms, the positive pole on the outer circumferential surface of the button battery and the negative pole on one side of the button battery may come into contact with the terminal on the operation panel board at the same time, resulting in a short circuit between the positive pole and the negative pole of the button battery. In contrast, in the present invention, by arranging the first terminal closer to the tip of the pair of arc-shaped arms than the center of the position where the button battery is arranged, as described above, the first terminal can be arranged at a position farther away from the positive pole on the outer circumferential surface of the button battery than when the first terminal is arranged in the center of the position where the button battery is arranged. As a result, when installing or removing the button battery (replacing the button battery), it is possible to prevent both the positive and negative poles of the button battery from coming into contact with the first terminal, which would cause a short circuit between the positive and negative poles of the button battery.

[0017] In the above-mentioned configuration in which the battery positioning portion includes a snap-fit ​​portion, preferably, the second terminal is disposed on the outer peripheral surface side of the button battery and is configured to be flexible, and the rear cover further includes a position restricting portion that restricts the position of the outer peripheral surface of the button battery relative to the second terminal in order to restrict the amount of flexible deformation of the second terminal. With this configuration, the amount of flexible deformation of the second terminal can be restricted when the button battery is installed and removed (when the button battery is replaced) by the position restricting portion that restricts the position of the outer peripheral surface of the button battery relative to the second terminal. As a result, it is possible to prevent damage to the second terminal due to excessive bending of the second terminal when the button battery is installed and removed (when the button battery is replaced).

[0018] In the above-mentioned configuration in which the battery positioning portion includes a snap-fit ​​portion, preferably, the second terminal is provided in a plurality of portions along the outer circumferential surface of the button battery. With this configuration, since the second terminal is provided in a plurality of portions along the outer circumferential surface of the button battery, even if the mounting position of the button battery is shifted on the operation panel board, Second Unlike the case where only one terminal is provided, any of the second terminals can be brought into contact with the button battery. As a result, Second Compared to when only one terminal is provided, this ensures more reliable contact between the button battery and the second terminal.

[0019] According to a second aspect of the present invention, an operation panel for a power conversion device includes an operation panel board having an operation unit on its front side for operating a power conversion device main body, a back cover including first and second terminals on a back side of the operation panel board corresponding to a button battery for supplying power to the operation panel board, a battery positioning portion for positioning the button battery with respect to the first and second terminals, and an opening provided so as to expose the battery positioning portion, the back cover being arranged to cover the back side of the operation panel board, and a battery cover configured to be attachable to and detachable from the back cover and provided so as to cover the opening, the operation panel further includes a card slot portion provided on the back side of the operation panel board for inserting a memory card, the operation panel board being provided with a stroke area for sliding the memory card to insert it into and remove it from the card slot portion, and the opening provided in the back cover so as to expose the battery positioning portion and the stroke area, The rear cover further includes an intrusion prevention portion that is provided along the outer edge of the stroke area so as to protrude toward the operation panel board and prevents the memory card from intruding between the rear cover and the operation panel board. With this configuration, it is possible to prevent the memory card from intruding between the rear cover and the operation panel board in the stroke area when inserting and removing the memory card into and from the card slot portion. As a result, it is possible to improve the operability when inserting and removing the memory card, which stores communication settings and communication logs with devices external to the power conversion device, into and from the card slot portion.

[0020] According to a third aspect of the present invention, an operation panel for a power conversion device includes an operation panel board having an operation unit on its front side for operating a power conversion device main body, a first terminal and a second terminal provided on the back side of the operation panel board corresponding to a button battery for supplying power to the operation panel board, a battery positioning unit for positioning the button battery with respect to the first terminal and the second terminal, and an opening provided so as to expose the battery positioning unit, the back cover being disposed to cover the back side of the operation panel board, and a battery cover configured to be attachable to and detachable from the back cover and provided to cover the opening, When the battery cover is attached to the rear cover, the battery cover includes a protruding portion that protrudes toward the first terminal provided on the operation panel board and presses the button battery toward the first terminal. With this configuration, the button battery is pressed toward the first terminal by the protruding portion of the battery cover, so that the button battery can be reliably contacted with the first terminal when the button battery is attached.

[0021] According to a fourth aspect of the present invention, an operation panel for a power conversion device includes an operation panel board having an operation unit on its front side for operating a power conversion device main body, a first terminal and a second terminal provided on the back side of the operation panel board corresponding to a button battery for supplying power to the operation panel board, a battery positioning unit for positioning the button battery with respect to the first terminal and the second terminal, and an opening provided so as to expose the battery positioning unit, the back cover being disposed to cover the back side of the operation panel board, and a battery cover configured to be attachable to and detachable from the back cover and provided to cover the opening, The power converter is configured so that the rear side of the operation panel body is attached to a control panel that houses the power conversion device main body and controls power, and further includes a seal member provided on the outside of the battery cover so as to surround the battery cover between the rear cover and the control panel. With this configuration, the seal member provided on the outside of the battery cover so as to surround the battery cover between the rear cover and the control panel can prevent water from entering between the rear cover and the control panel when the rear side of the operation panel body is attached to the control panel. As a result, when the rear side of the operation panel body is attached to the control panel, water can be prevented from entering between the rear cover and the battery cover.

[0022] In the power conversion device operation panel according to the fourth aspect, Preferably, the battery cover is disposed near the center of the surface of the rear cover facing the control panel, and the rear cover has a groove formed along the vicinity of the outer periphery of the surface of the rear cover facing the control panel, into which the seal member is fitted. With this configuration, the seal member is disposed along the vicinity of the outer periphery of the surface of the rear cover facing the control panel, so that the area in which water can be prevented from entering between the rear cover and the control panel can be relatively large on the surface of the rear cover facing the control panel. In addition, by disposing the battery cover near the center of the surface of the rear cover facing the control panel, the battery cover can be easily surrounded by the seal member compared to the case where the battery cover is provided near the outer periphery of the surface of the rear cover facing the control panel. As a result, water can be easily prevented from entering between the rear cover and the battery cover.

[0058] As shown in FIG. 5, a display 1, a switch 4, and a connector 5 are provided (mounted) on the front side (Y1 direction side) of the operation panel board 50. A plurality of switches 4 are provided corresponding to the plurality of operation buttons 2. The connector 5 is provided for connecting to an external device of the power conversion device 100 (control panel 110) such as a PC (Personal Computer) so as to be able to communicate with the external device of the power conversion device 100 (control panel 110) such as a PC. For example, the connector 5 is a USB terminal that is connected to an external device of the power conversion device 100 (control panel 110) such as a PC so as to be able to communicate with the external device. The display 1, the switch 4, and the connector 5 are electrically connected to a wiring pattern formed on the operation panel board 50.

[0059] 5, a connector 6, a connector 7, a negative terminal 51, a positive terminal 52, and a card slot section 53 are provided (mounted) on the back side (Y2 direction side) of the operation panel board 50. Also, when viewed from the back side (Y2 direction side) of the operation panel board 50, the positive terminal 52, the negative terminal 51, and the card slot section 53 are arranged in this order from the X1 direction side. The negative terminal 51, the positive terminal 52, and the card slot section 53 are electrically connected to a wiring pattern formed on the operation panel board 50.

[0060] Moreover, the negative terminal 51, the positive terminal 52, and the card slot section 53 are provided near the center of the back side (Y2 direction side) of the operation panel substrate 50 in the Z direction. Moreover, the negative terminal 51, the positive terminal 52, and the card slot section 53 are arranged at positions overlapping with the display 1 provided on the front side (Y1 direction side) of the operation panel substrate 50 when viewed from the Y direction (Y1 direction side or Y2 direction side) (see FIG. 5).

[0061] As shown in FIG. 6, the battery cover 30 is disposed near the center of the surface 20a of the rear cover 20 that faces the control panel 110.

[0062] The battery cover 30 is provided so as to cover the opening A1 (see FIG. 4). As shown in FIG. 6, when the battery cover 30 is attached, the claw portion 21b of the snap fit portion 21, which will be described later, is exposed from the hole 30a of the battery cover 30.

[0063] 6, the seal member 40 is disposed so as to surround the connector 6 (opening A2), the connector 7 (opening A3), and the fastening hole H1. That is, the operation panel 101 is attached to the control panel 110 by using the fastening hole H1 provided on the inner side of the seal member 40 on the surface 20a of the rear cover 20 facing the control panel 110.

[0064] 7, when the rear side (Y2 direction side) of the operation panel 101 is attached to the control panel 110, the sealing member 40 is disposed between the rear cover 20 and the control panel 110. The sealing member 40 is configured to be pressed against the control panel 110 and elastically deformed when the main body (rear cover 20) of the operation panel 101 is attached to the control panel 110.

[0065] As shown in Fig. 8, the positive terminal 52 is disposed on the outer peripheral surface P side of the button battery B and is configured to be flexible. As shown in Fig. 8, the rear cover 20 includes a position restricting portion 23 that restricts the position of the outer peripheral surface P of the button battery B relative to the positive terminal 52 in order to restrict the amount of flexible deformation of the positive terminal 52. The position restricting portion 23 is a step provided in the rear cover 20, and the button battery B gets caught on the position restricting portion 23 (step), thereby restricting movement of the button battery B in the X1 direction.

[0066] Furthermore, the battery cover 30 includes a protrusion 31 (see FIG. 8) that, when attached to the rear cover 20, protrudes toward the negative terminal 51 (Y1 direction) provided on the operation panel board 50 and presses the button battery B toward the negative terminal 51. The tip (the end on the Y1 direction side) of the protrusion 31 is formed flat, and when the battery cover 30 is attached, the tip of the protrusion 31 presses the button battery B from the Y2 direction.

[0067] As shown in FIG. 9, the operation panel board 50 is provided with a stroke area S for sliding the memory card C to insert it into the card slot portion 53 and remove it from the card slot portion 53.

[0068] 9, the positive terminal 52 is disposed outside (X1 direction) of the opening A1 provided on the surface 20a of the rear cover 20 when viewed from the Y2 direction. Also, as shown in Fig. 9, when the button battery B is attached, a part of the positive terminal 52 side (X1 direction) of the button battery B is disposed outside (X1 direction) of the opening A1 provided on the surface 20a of the rear cover 20 when viewed from the Y2 direction. In other words, the Y2 side of the positive terminal 52 and a part of the positive terminal 52 side of the button battery B are covered by the rear cover 20.

[0069] 9, the stroke area S is provided between the card slot portion 53 and the snap-fit ​​portion 21. The stroke area S is an area for sliding the memory card C, and is an area on the rear surface (the surface on the Y2 direction side) of the operation panel substrate 50 where components constituting an electronic circuit, such as the electronic component EC, are not attached (mounted).

[0070] This allows the user to insert the memory card C into the card slot section 53 by sliding the memory card C from the stroke area S to the card slot section 53 side (X2 direction side). The user can then remove the memory card C from the card slot section 53 by sliding the memory card C from the card slot section 53 to the stroke area S side (X1 direction side).

[0071] 9, in this embodiment, a plurality (two) of positive terminals 52 are provided along the outer peripheral surface P of the button battery B. The multiple positive terminals 52 are electrically connected to each other by a conductor pattern formed on the operation panel substrate 50.

[0072] As shown in FIG. 9, the snap-fit ​​portion 21 is provided so as to fit along the outer peripheral surface P of the button battery B, and is configured to be flexible and deformable when the button battery B is attached and detached.

[0073] As shown in FIG. 9, the snap-fit ​​portion 21 includes a pair of arc-shaped arms 21a that are provided in an arc shape along the outer circumferential surface P of the button battery B and are elastically deformable.

[0074] As shown in FIG. 9, the snap-fit ​​portion 21 has tips of a pair of arc-shaped arms 21a provided on the side of the button battery B where the stroke region S is located (the X2 direction side).

[0075] 9, the snap-fit ​​portion 21 includes a claw portion 21b provided near the tip end of the pair of arc-shaped arms 21a. The claw portion 21b is configured to cover (press) a part of the button battery B from the Y2 direction side when the button battery B is attached in the area surrounded by the pair of arc-shaped arms 21a.

[0076] 10, rear cover 20 includes intrusion prevention portion 24 that protrudes toward operation panel board 50 (Y1 direction side) to prevent memory card C from entering between rear cover 20 and operation panel board 50. Intrusion prevention portion 24 is provided along the outer edge of stroke area S as shown in FIG.

[0077] Further, distance D1 (see FIG. 10) between intrusion prevention unit 24 and operation panel board 50 in the Y direction is smaller than width W (see FIG. 10) in the Y direction of insertion opening 53a of card slot 53 into which memory card C is inserted. Distance D1 (see FIG. 10) between intrusion prevention unit 24 and operation panel board 50 in the Y direction is large enough to prevent memory card C from entering between rear cover 20 and operation panel board 50.

[0078] As shown in FIG. 11, when installing button battery B, the user tilts (slants) button battery B with respect to the X direction along the back surface of operation panel substrate 50, and pushes apart (deflects) the pair of arc-shaped arms 21a of snap-fit ​​portion 21 to install button battery B.

[0079] 11 and 12, the rear cover 20 includes a deflection restricting portion 22 that restricts the amount of deflection deformation of the snap-fit ​​portion 21 when the button battery B is attached and detached. The deflection restricting portion 22 is an arc-shaped wall formed (arranged) along a pair of arc-shaped arms 21a of the snap-fit ​​portion 21.

[0080] 12, the snap-fit ​​portion 21 is provided with a positioning protrusion 21c in order to position the button battery B relative to the positive terminal 52. The positioning protrusion 21c protrudes from the side on which the button battery B is arranged and also from the side on which the positive terminal 52 is arranged.

[0081] Specifically, the positioning protrusion 21c is provided on the inner side of each of the pair of arc-shaped arms 21a. That is, one positioning protrusion 21c is provided for one arm 21a. The positioning protrusion 21c is configured to protrude in an arc shape from the inner side of each of the pair of arc-shaped arms 21a toward the button battery B side (negative terminal 51 side). The positioning protrusion 21c is provided on the operation panel board 50 side (Y1 direction side) with respect to the claw portion 21b. As shown in FIG. 12, the arm 21a, the positioning protrusion 21c, the deflection restriction portion 22, and the intrusion prevention portion 24 are formed continuously (integrally).

[0082] 12, the opening A1 is provided in the rear cover 20 so as to expose the snap fit portion 21 and the stroke region S. The opening A1 is provided in the rear cover 20 so as to expose the deflection restricting portion 22 and the negative terminal 51. The opening A1 is formed in a stepped shape, and is configured to expose the operation panel board 50 along the outer edges of the arm portion 21a, the positioning protrusion 21c, the deflection restricting portion 22, and the intrusion preventing portion 24.

[0083] In addition, as shown in FIG. 13, in the area surrounded by the pair of arc-shaped arms 21a, the negative terminal 51 is located closer to the tip of the pair of arc-shaped arms 21a (X2 direction side) than the center of the position where the button battery B is located.

[0084] As shown in FIG. 14, since the Y2 side of the positive terminal 52 is covered by the rear cover 20, the user inserts (attaches) the button battery B into the area surrounded by the pair of arc-shaped arms 21a with the outer peripheral surface P on the X1 side facing the Y1 side and tilted (slanted) with respect to the X direction along the rear surface of the operation panel board 50.

[0085] Therefore, the position of the negative terminal 51 is such that the positive and negative poles of the button battery B are not short-circuited even when the button battery B is inserted at an angle (inserted diagonally) into the area surrounded by a pair of arc-shaped arms 21a.

[0086] Specifically, the negative terminal 51 is positioned at a position shifted toward the X2 direction from the center of the position where the button battery B is positioned, to a position where the inclination angle of the button battery B with respect to the negative terminal 51 can be increased to an angle θ (see Figure 15) at which both the positive and negative poles of the button battery B do not contact the negative terminal 51 at the same time by interfering with the pair of arc-shaped arms 21a with the button battery B.

[0087] (Effects of this embodiment) In this embodiment, the following effects can be obtained.

[0088] In this embodiment, the operation button 2 (switch 4) for operating the power converter main body 102 is provided on the front side (Y1 direction side) of the operation panel board 50. A negative terminal 51 and a positive terminal 52 are provided on the back side (Y2 direction side) of the operation panel board 50 corresponding to the button battery B. This allows the button battery B to be mounted on the back side (Y2 direction side) of the operation panel board 50 on which the negative terminal 51 and the positive terminal 52 are provided, so that the space on the operation button 2 (switch 4) side of the operation panel 101 can be prevented from becoming narrow, unlike the case where the button battery B is mounted on the front side (Y1 direction side) of the operation panel board 50 on which the operation button 2 (switch 4) is provided. In addition, the battery cover 30 configured to be attachable and detachable to the rear cover 20 covers the opening A1 provided so that the snap fit portion 21 is exposed, so that the user can attach and remove the button battery B from the snap fit portion 21 that positions the button battery B (replace the button battery B) by removing the battery cover 30. As a result, it is possible to provide an operation panel 101 and a power conversion device 100 that can accommodate a replaceable button battery B for supplying power to the operation panel 101 while preventing the space on the operation button 2 (switch 4) side of the operation panel 101 from becoming narrow.

[0089] In this embodiment, as described above, the operation panel 101 body is detachably attached to the power converter body 102. This allows the button battery B to be easily attached to and detached from (replaced) the negative terminal 51 and the positive terminal 52 provided on the rear surface (the surface on the Y2 direction side) of the operation panel board 50.

[0090] In addition, in this embodiment, as described above, the back surface (surface on the Y2 direction side) of the operation panel substrate 50 is provided with the card slot portion 53 for inserting the memory card C, so that the memory card C can be mounted on the back surface of the operation panel substrate 50, and the memory card C can store communication settings and communication logs with devices outside the power conversion device 100. In addition, by providing the stroke area S for sliding the memory card C to insert it into the card slot portion 53 and remove it from the card slot portion 53 on the operation panel substrate 50, the memory card C can be easily inserted into the card slot portion 53 and removed from the card slot portion 53. Furthermore, by providing the opening A1 on the rear cover 20 so that the snap fit portion 21 and the stroke area S are exposed, the battery cover 30 provided to cover the opening A1 can be provided in common with the snap fit portion 21 and the stroke area S. As a result, it is possible to suppress an increase in the number of parts and a complication of the device configuration.

[0091] In the present embodiment, as described above, the stroke area S is provided between the card slot 53 and the snap-fit ​​portion 21. This allows the snap-fit ​​portion 21 and the stroke area S to be closer to each other, unlike the case where the stroke area S is provided on the opposite side (X2 direction side) of the side where the snap-fit ​​portion 21 is arranged with respect to the card slot 53. This allows the opening A1 where the snap-fit ​​portion 21 and the stroke area S are exposed to be made smaller. As a result, it is possible to prevent foreign matter from entering the inside of the operation panel 101 when a user removes the battery cover 30 provided to cover the opening A1 to perform work.

[0092] Furthermore, in this embodiment, as described above, the snap-fit ​​portion 21 is configured to be able to flex and deform when the button battery B is attached and removed, and the back cover 20 includes a deflection restriction portion 22 that restricts the amount of deflection of the snap-fit ​​portion 21 when the button battery B is attached and removed. This makes it possible to restrict the amount of deflection of the snap-fit ​​portion 21 by the deflection restriction portion 22, thereby making it possible to prevent damage to the snap-fit ​​portion 21 due to excessive deflection of the snap-fit ​​portion 21 when attaching and removing the button battery B (replacing the button battery B).

[0093] In this embodiment, as described above, the snap-fit ​​portion 21 is provided along the outer peripheral surface P of the button battery B and is configured to be flexible and deformable when the button battery B is attached and removed. This allows the snap-fit ​​portion 21 to be flexible and deformable when the button battery B is attached and removed, making it easy to attach and remove the button battery B (replace the button battery B). In addition, the snap-fit ​​portion 21 is provided along the outer peripheral surface P of the button battery B with a positioning protrusion 21c that protrudes on the side where the button battery B is located and on the side where the positive terminal 52 is located, so that the button battery B attached to the snap-fit ​​portion 21 can be pressed against the positive terminal 52. As a result, the button battery B and the positive terminal 52 can be reliably brought into contact with each other when the button battery B is attached.

[0094] In this embodiment, as described above, the snap-fit ​​portion 21 includes a pair of elastically deformable arc-shaped arms 21a that are provided in an arc shape along the outer peripheral surface P of the button battery B, and the tips of the pair of arc-shaped arms 21a are provided on the side (X2 direction side) where the stroke region S is located relative to the button battery B. This allows the user to easily push apart the pair of elastically deformable arc-shaped arms 21a of the snap-fit ​​portion 21 from the stroke region S side when removing the button battery B. As a result, the button battery B can be easily removed.

[0095] In this embodiment, as described above, the negative terminal 51 is disposed on the tip side of the pair of arc-shaped arms 21a rather than the center of the position where the button battery B is disposed in the area surrounded by the pair of arc-shaped arms 21a. By disposing the negative terminal 51 on the tip side of the pair of arc-shaped arms 21a rather than the center of the position where the button battery B is disposed, the negative terminal 51 can be disposed at a position farther away from the positive pole provided on the outer peripheral surface P of the button battery B than when the negative terminal 51 is disposed at the center of the position where the button battery B is disposed. As a result, when the button battery B is attached and detached (replaced), it is possible to prevent both the positive pole and the negative pole of the button battery B from contacting the negative terminal 51, which causes a short circuit between the positive pole and the negative pole of the button battery B.

[0096] In this embodiment, as described above, the positive terminal 52 is disposed on the outer peripheral surface P side of the button battery B and is configured to be flexible. The rear cover 20 includes a position restricting portion 23 that restricts the position of the outer peripheral surface P of the button battery B relative to the positive terminal 52 in order to restrict the amount of flexible deformation of the positive terminal 52. This allows the position restricting portion 23 that restricts the position of the outer peripheral surface P of the button battery B relative to the positive terminal 52 to restrict the amount of flexible deformation of the positive terminal 52 when the button battery B is installed and removed (replacement of the button battery B). As a result, damage to the positive terminal 52 due to excessive bending of the positive terminal 52 can be prevented when the button battery B is installed and removed (replacement of the button battery B).

[0097] Furthermore, in this embodiment, as described above, multiple (two) positive terminals 52 are provided along the outer peripheral surface P of the button battery B. As a result, since multiple (two) positive terminals 52 are provided along the outer peripheral surface P of the button battery B, even if the mounting position of the button battery B is misaligned on the operation panel board 50, unlike when only one positive terminal 52 is provided, any one of the positive terminals 52 can be brought into contact with the button battery B. As a result, the button battery B and the positive terminal 52 can be brought into contact more reliably than when only one positive terminal 52 is provided.

[0098] In the present embodiment, as described above, the rear cover 20 includes an intrusion prevention portion 24 that is provided along the outer edge of the stroke area S so as to protrude toward the operation panel board 50 side (Y1 direction side) and prevents the memory card C from intruding between the rear cover 20 and the operation panel board 50. This makes it possible to prevent the memory card C from intruding between the rear cover 20 and the operation panel board 50 when inserting and removing the memory card C into and from the card slot portion 53 in the stroke area S. As a result, it is possible to improve the operability when inserting and removing the memory card C, which stores communication settings and communication logs with devices external to the power conversion device 100, into and from the card slot portion 53.

[0099] Furthermore, in this embodiment, as described above, the battery cover 30, when attached to the rear cover 20, includes a protrusion 31 that protrudes toward the negative terminal 51 (Y1 direction) provided on the operation panel board 50 and presses the button battery B toward the negative terminal 51. As a result, the protrusion 31 of the battery cover 30 presses the button battery B toward the negative terminal 51 (Y1 direction), so that the button battery B and the negative terminal 51 can be reliably contacted when attaching the button battery B.

[0100] In addition, in this embodiment, as described above, the power converter main body 102 is accommodated, and the rear side (Y2 direction side) of the operation panel 101 body is configured to be attached to the control panel 110 that controls power. A seal member 40 is provided between the rear cover 20 and the control panel 110 and is provided on the outside of the battery cover 30 so as to surround the battery cover 30. This makes it possible to prevent water from entering between the rear cover 20 and the control panel 110 when the rear side (Y2 direction side) of the operation panel 101 body is attached to the control panel 110 by the seal member 40 provided on the outside of the battery cover 30 so as to surround the battery cover 30 between the rear cover 20 and the control panel 110. As a result, when the rear side (Y2 direction side) of the operation panel 101 body is attached to the control panel 110, it is possible to prevent water from entering between the rear cover 20 and the battery cover 30.

[0101] In this embodiment, as described above, the battery cover 30 is disposed near the center of the surface 20a of the rear cover 20 facing the control panel 110. The rear cover 20 has a groove 25 formed along the vicinity of the outer periphery of the surface 20a of the rear cover 20 facing the control panel 110, into which the seal member 40 is fitted. As a result, the seal member 40 is disposed along the vicinity of the outer periphery of the surface 20a of the rear cover 20 facing the control panel 110, so that the area on the surface 20a of the rear cover 20 facing the control panel 110 that can prevent water from entering between the rear cover 20 and the control panel 110 can be relatively large. In addition, by disposing the battery cover 30 near the center of the surface 20a of the rear cover 20 facing the control panel 110, the battery cover 30 can be easily surrounded by the seal member 40 compared to the case where the battery cover 30 is provided near the outer periphery of the surface 20a of the rear cover 20 facing the control panel 110. As a result, water can be easily prevented from entering between the rear cover 20 and the battery cover 30.

[0102] [Variations] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects.
