Description

TECHNICAL FIELD

[0001] The present application relates to an operation panel for a power conversion device and a power conversion device, and particularly relates to an operation panel for a power conversion device and a power conversion device provided with an operation section for performing an operation on a main body section of a power conversion device. BACKGROUND

[0002] Conventionally, an operation panel for a power conversion device provided with an operation section (switch) for performing an operation on a main body section of a power conversion device is known. Such an operation panel for a power conversion device is disclosed, for example, in Japanese Patent Application Publication No. 2005-117733.

[0003] In Japanese Patent Application Publication No. 2005-117733, an operation panel for a power conversion device is disclosed, which is provided with a switch for selecting a method of operation of a main body section of a power conversion device, a switch for selecting a setting of an output frequency of the main body section of the power conversion device, and a connector connected to the main body section of the power conversion device.

[0004] Here, in recent years, the functions required of an operation panel for a power conversion device have increased, and in addition to being required to be able to communicate with an external device, it is also required to be able to function even when power supply from the main body section of the power conversion device is blocked. Therefore, an operation panel is required which mounts a coin cell battery as an auxiliary power source for the operation panel at the time of blocking of power supply and which is able to replace the coin cell battery.

[0005] However, in the conventional operation panel for a power conversion device described in Japanese Patent Application Publication No. 2005-117733, the operation section (switch) for performing an operation on the main body section of the power conversion device is provided on the operation panel, and therefore, if a coin cell battery is mounted as an auxiliary power source on the operation section side so as to be replaceable, the space on the operation section side becomes narrow, and as a result, it is not possible to provide a communication connector or the like for communication with an external device on the operation section side. In addition, since the size of the main body of the operation panel is determined by the main body section of the power conversion device to which the operation panel is connected, it is not possible to easily change the size of the main body of the operation panel, and therefore, it is difficult to increase the printed board for actually mounting a communication connector or the like. As a result, an operation panel for a power conversion device and a power conversion device are desired which are able to replaceably mount a coin cell battery for supplying power to the operation panel and which are able to suppress the narrowing of the space on the operation section side. SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] The present application has been made to solve the above-described problems, and an object of the present application is to provide an operation panel for a power conversion device and a power conversion device capable of detachably mounting a button cell for supplying electric power to the operation panel and capable of suppressing narrowing of a space on the operation portion side.

[0008] Solution to Problem

[0009] To achieve the above object, a first aspect of the present application provides an operation panel for a power conversion device, wherein the operation panel for a power conversion device includes: an operation panel substrate provided on a surface side thereof with an operation portion for performing operation on a main body portion of a power conversion device; a first terminal and a second terminal provided on a back surface of the operation panel substrate corresponding to a button cell for supplying electric power to the operation panel substrate; a back surface cover including a battery positioning portion for positioning the button cell with respect to the first terminal and the second terminal and an opening portion provided in such a manner as to expose the battery positioning portion, the back surface cover being disposed in such a manner as to cover the back surface of the operation panel substrate; and a battery cover configured to be attachable to and detachable from the back surface cover, the battery cover being provided in such a manner as to cover the opening portion.

[0010] In the operation panel for a power conversion device according to the first aspect described above, the operation portion for performing operation on the main body portion of the power conversion device is provided on the surface side of the operation panel substrate as described above. Also, the first terminal and the second terminal are provided on the back surface of the operation panel substrate corresponding to the button cell. Thus, the button cell can be mounted on the back surface of the operation panel substrate on which the first terminal and the second terminal are provided, and therefore, unlike the case where the button cell is mounted on the surface side of the operation panel substrate on which the operation portion is provided, narrowing of the space on the operation portion side of the operation panel can be suppressed. Also, the opening portion provided in such a manner as to expose the battery positioning portion is covered by the battery cover configured to be attachable to and detachable from the back surface cover, and therefore, the user can perform attachment and detachment (replacement) of the button cell with respect to the battery positioning portion for positioning the button cell by detaching the battery cover. As a result, the button cell for supplying electric power to the operation panel can be detachably mounted, and narrowing of the space on the operation portion side can be suppressed.

[0011] In the operation panel for a power conversion device according to the first aspect described above, it is preferable that the operation panel main body be mounted in such a manner as to be detachable with respect to the main body portion of the power conversion device. If configured as such, even in the case where the operation panel main body is mounted on the back surface side thereof to the main body portion of the power conversion device, attachment and detachment (replacement) of the button cell with respect to the first terminal and the second terminal provided on the back surface of the operation panel substrate can be easily performed by detaching the operation panel main body from the main body portion of the power conversion device.

[0012] In the operation panel for a power conversion device according to the above-mentioned first aspect, preferably, the operation panel for a power conversion device further includes a card slot portion provided on the back surface of the operation panel substrate for insertion of a memory card, a stroke area is provided on the operation panel substrate for sliding of the memory card to perform insertion into and extraction from the card slot portion, and an opening portion is provided on the back surface cover so as to expose the battery positioning portion and the stroke area. Here, as a function required for the operation panel for a power conversion device, it is sought to be able to mount a memory card that stores communication settings, communication logs, and the like between the power conversion device and an external device (apparatus). If configured as described above, the card slot portion for insertion of a memory card is provided on the back surface of the operation panel substrate, and thus the memory card is mounted on the back surface of the operation panel substrate, and it is possible to cause the memory card to store communication settings, communication logs, and the like between the power conversion device and an external device. In addition, if configured as described above so that the stroke area for sliding of the memory card to perform insertion into and extraction from the card slot portion is provided on the operation panel substrate, it is possible to easily perform insertion of the memory card into the card slot portion and extraction of the memory card from the card slot portion. Furthermore, if configured so that the opening portion is provided on the back surface cover so as to expose the battery positioning portion and the stroke area as described above, it is possible to provide a battery cover provided so as to cover the opening portion in common with respect to the battery positioning portion and the stroke area. As a result, it is possible to suppress an increase in the number of components and complication of the device structure.

[0013] In the structure provided with the above-mentioned card slot portion, preferably, the stroke area is provided between the card slot portion and the battery positioning portion. If configured thus, unlike a case where the stroke area is provided on the side opposite to the side on which the battery positioning portion is disposed with respect to the card slot portion, it is possible to bring the battery positioning portion and the stroke area close to each other. Thus, it is possible to reduce the opening portion that exposes the battery positioning portion and the stroke area. As a result, when a user detaches the battery cover provided so as to cover the opening portion and performs work, it is possible to suppress entry of foreign matter into the inside of the operation panel.

[0014] In the structure provided with the above-mentioned card slot portion, preferably, the battery positioning portion is configured to be able to deform by flexure at the time of attachment and detachment of the coin battery, and the back surface cover further includes a flexure restriction portion that restricts the amount of deformation by flexure of the battery positioning portion at the time of attachment and detachment of the coin battery. If configured thus, it is possible to restrict the amount of deformation by flexure of the battery positioning portion by the flexure restriction portion, and thus, at the time of attachment and detachment of the coin battery (replacement of the coin battery), it is possible to suppress breakage of the battery positioning portion due to excessive flexure of the battery positioning portion.

[0015] In the structure in which the stroke region is provided between the card slot portion and the battery positioning portion, it is preferable that the battery positioning portion include a snap-fitting portion provided in a manner along the outer circumferential surface of the button cell and configured to be able to be elastically deformed at the time of attachment and detachment of the button cell, and that a positioning protrusion protruding toward the side on which the button cell is disposed and the side on which the second terminal is disposed be provided in the snap-fitting portion so as to position the position of the button cell with respect to the second terminal. If so configured, the snap-fitting portion is elastically deformed at the time of attachment and detachment of the button cell, and thus attachment and detachment (replacement) of the button cell can be easily performed. Further, by providing the positioning protrusion protruding toward the side on which the button cell is disposed and the side on which the second terminal is disposed in the snap-fitting portion provided in a manner along the outer circumferential surface of the button cell, the button cell attached to the snap-fitting portion can be pressed toward the second terminal side. As a result, the button cell and the second terminal can be reliably brought into contact with each other at the time of attachment of the button cell.

[0016] In the structure in which the battery positioning portion includes the snap-fitting portion, the snap-fitting portion includes a pair of arc-shaped arm portions elastically deformable in a circular arc shape along the outer circumferential surface of the button cell, and the tips of the pair of arc-shaped arm portions are disposed on the side on which the stroke region is disposed with respect to the button cell. If so configured, the user can easily spread the pair of arc-shaped arm portions elastically deformable of the snap-fitting portion from the stroke region side at the time of detachment of the button cell. As a result, detachment of the button cell can be easily performed.

[0017] In this case, it is preferable that the first terminal be disposed in a position on the tip side of the pair of arc-shaped arm portions with respect to a central portion of the position on which the button cell is disposed in a region surrounded by the pair of arc-shaped arm portions. Here, the button cell has a negative electrode on one side surface and a positive electrode on the other side surface, and also has a positive electrode on the outer circumferential surface. Thus, there is a case in which, when the button cell is obliquely inserted into the region surrounded by the pair of arc-shaped arm portions from the tip side of the pair of arc-shaped arm portions, the positive electrode provided on the outer circumferential surface of the button cell and the negative electrode provided on the one side surface of the button cell simultaneously come into contact with the terminals provided in the operation panel substrate, and the positive electrode and the negative electrode of the button cell are short-circuited. In contrast, in the present application, as described above, by disposing the first terminal in a position on the tip side of the pair of arc-shaped arm portions with respect to a central portion of the position on which the button cell is disposed, the first terminal can be disposed in a position separate from the positive electrode provided on the outer circumferential surface of the button cell, as compared with the case in which the first terminal is disposed in the central portion of the position on which the button cell is disposed. As a result, it is possible to prevent the positive electrode and the negative electrode of the button cell from coming into contact with the first terminal and the positive electrode and the negative electrode of the button cell from being short-circuited at the time of attachment and detachment (replacement) of the button cell.

[0018] In the structure in which the battery positioning portion includes the snap-fit portion, it is preferable that the second terminal be disposed at the outer peripheral surface side of the button cell and be configured to be able to be flexibly deformed, and the back cover further include a position limiting portion that limits the position of the outer peripheral surface of the button cell with respect to the second terminal, so as to limit the amount of flexural deformation of the second terminal. If so configured, the position limiting portion that limits the position of the outer peripheral surface of the button cell with respect to the second terminal is able to limit the amount of flexural deformation of the second terminal at the time of mounting and dismounting of the button cell (replacement of the button cell). As a result, it is possible to prevent the second terminal from being damaged due to excessive flexure of the second terminal at the time of mounting and dismounting of the button cell (replacement of the button cell).

[0019] In the structure in which the battery positioning portion includes the snap-fit portion, it is preferable that a plurality of second terminals be provided along the outer peripheral surface of the button cell. If so configured, a plurality of second terminals are provided along the outer peripheral surface of the button cell, so that even if the mounting position of the button cell is shifted on the operation panel substrate, any one of the second terminals is able to be brought into contact with the button cell, unlike the case in which only one second terminal is provided. As a result, the button cell and the second terminal are able to be reliably brought into contact with each other, as compared with the case in which only one second terminal is provided.

[0020] In the structure including the card slot portion, it is preferable that the back cover further include an entry preventing portion that is provided along the outer edge of the stroke region in a manner that protrudes toward the operation panel substrate side, so as to prevent the memory card from entering between the back cover and the operation panel substrate. If so configured, the memory card is able to be prevented from entering between the back cover and the operation panel substrate at the time of insertion and extraction of the memory card with respect to the card slot portion in the stroke region. As a result, the operability at the time of insertion and extraction of the memory card with respect to the card slot portion for storing the communication setting, communication log, and the like between the power conversion device and the external device is able to be improved.

[0021] In the operation panel for a power conversion device according to the first technical aspect, it is preferable that the battery cover include a protruding portion that protrudes toward the first terminal side of the operation panel substrate to press the button cell toward the first terminal side in a state in which the battery cover is mounted to the back cover. If so configured, the button cell is pressed toward the first terminal side by the protruding portion of the battery cover, so that the button cell and the first terminal are able to be reliably brought into contact with each other at the time of mounting of the button cell.

[0022] In the operation panel for a power conversion device according to the above-described first aspect, it is preferable that the back surface side of the operation panel main body be mounted to a control panel that houses the power conversion device main body portion and performs power control. A sealing member that is provided outside the battery cover in a manner of surrounding the battery cover is further provided between the back surface cover and the control panel. If configured as such, water can be prevented from entering between the back surface cover and the control panel in a state where the back surface side of the operation panel main body is mounted to the control panel, using the sealing member that is provided outside the battery cover in a manner of surrounding the battery cover. As a result, water can be prevented from entering between the back surface cover and the battery cover in a state where the back surface side of the operation panel main body is mounted to the control panel.

[0023] In this case, it is preferable that the battery cover be disposed at a central portion of a surface of the back surface cover that is opposite the control panel, and the back surface cover have a groove portion that is formed along an outer peripheral portion of the surface of the back surface cover that is opposite the control panel, into which the sealing member is fitted. If configured as such, the sealing member is disposed along the outer peripheral portion of the surface of the back surface cover that is opposite the control panel, and thus the area of the surface of the back surface cover that is opposite the control panel, in which water can be prevented from entering between the back surface cover and the control panel, can be made relatively large. Further, by disposing the battery cover at a central portion of the surface of the back surface cover that is opposite the control panel, the battery cover can be easily surrounded by the sealing member, as compared to a case where the battery cover is disposed at an outer peripheral portion of the surface of the back surface cover that is opposite the control panel. As a result, water can be easily prevented from entering between the back surface cover and the battery cover.

[0024] To achieve the above object, a second aspect of the present application provides a power conversion device, including: a power conversion device main body portion; and an operation panel mounted in a manner that is detachable with respect to the power conversion device main body portion and that receives an operation of the power conversion device main body portion, the operation panel including: an operation panel substrate provided with an operation portion on a surface side for performing the operation of the power conversion device main body portion; a first terminal and a second terminal provided on a back surface of the operation panel substrate corresponding to a button cell for supplying power to the operation panel substrate; a back surface cover including a battery positioning portion that positions the button cell with respect to the first terminal and the second terminal and an opening portion provided in a manner that exposes the battery positioning portion, the back surface cover being disposed in a manner of covering the back surface of the operation panel substrate; and a battery cover configured to be mounted and detached with respect to the back surface cover and provided in a manner of covering the opening portion.

[0025] In the power conversion device according to the above-described second aspect, as described above, the operation portion for performing the operation of the power conversion device main body is provided on the surface side of the operation panel substrate. Also, the first terminal and the second terminal are provided on the back surface of the operation panel substrate in correspondence with the button cell. Thus, the button cell can be mounted on the back surface of the operation panel substrate on which the first terminal and the second terminal are provided, and thus, unlike the case where the button cell is mounted on the surface side of the operation panel substrate on which the operation portion is provided, the space on the operation portion side can be prevented from being narrowed. Further, the battery cover configured to be attached to and detached from the back surface of the operation panel is configured to cover the opening portion provided so as to expose the battery positioning portion. Thus, the user can attach and detach the button cell with respect to the battery positioning portion for positioning the button cell by detaching the battery cover from the operation panel detached from the power conversion device main body. As a result, the power conversion device capable of detachably mounting the button cell for supplying electric power to the operation panel and capable of preventing the space on the operation portion side of the operation panel from being narrowed can be provided. Further, by attaching the operation panel so as to be detachable with respect to the power conversion device main body, even in the case where the operation panel main body is attached to the power conversion device main body on the back surface side thereof, by detaching the operation panel main body from the power conversion device main body, the attachment and detachment (replacement) of the button cell with respect to the first terminal and the second terminal provided on the back surface of the operation panel substrate can be easily performed.

The sealing member 40 is configured to be elastically deformed by being pressed against the control disk 110 when the main body (back cover 20) of the operation panel 101 is attached to the control disk 110.

[0082] In addition, as shown in FIG. 2, the positive terminal 52 is disposed on the outer peripheral surface P side of the coin battery B and is configured to be able to be elastically deformed. Figure 8 As shown, the back cover 20 includes a position restriction portion 23 that restricts the position of the outer peripheral surface P of the coin battery B with respect to the positive terminal 52 so as to restrict the amount of elastic deformation of the positive terminal 52. The position restriction portion 23 is a step provided to the back cover 20, and the coin battery B is hooked to the position restriction portion 23 (step) so as to restrict movement of the coin battery B to the Xl direction side. Figure 8 As shown, the back cover 20 includes a position restriction portion 23 that restricts the position of the outer peripheral surface P of the coin battery B with respect to the positive terminal 52 so as to restrict the amount of elastic deformation of the positive terminal 52. The position restriction portion 23 is a step provided to the back cover 20, and the coin battery B is hooked to the position restriction portion 23 (step) so as to restrict movement of the coin battery B to the Xl direction side.

[0083] In addition, the battery cover 30 includes a protruding portion 31 (see FIG. 3) that protrudes toward the negative terminal 51 side (Yl direction side) of the operation panel substrate 50 and presses the coin battery B toward the negative terminal 51 side in a state in which the battery cover 30 is attached to the back cover 20. Figure 8 As shown, the top end (end portion on the Yl direction side) of the protruding portion 31 is flat, and the top end of the protruding portion 31 presses the coin battery B from the Y2 direction side in a state in which the battery cover 30 is attached.

[0084] As shown, a stroke region S is provided to the operation panel substrate 50, and the stroke region S is used to slide the memory card C so as to perform insertion into and extraction from the card slot portion 53. Figure 9 In addition, as shown in FIG. 2, the positive terminal 52 is disposed on the outer peripheral surface P side of the coin battery B and is configured to be able to be elastically deformed.

[0085] As shown, the top end (end portion on the Yl direction side) of the protruding portion 31 is flat, and the top end of the protruding portion 31 presses the coin battery B from the Y2 direction side in a state in which the battery cover 30 is attached. Figure 9 As shown, the positive terminal 52 is disposed on the outside (Xl direction side) of the opening portion Al provided to the face 20a of the back cover 20 when viewed from the Y2 direction side. In addition, as shown in FIG. 2, the portion of the coin battery B on the positive terminal 52 side (Xl direction side) is disposed on the outside (Xl direction side) of the opening portion Al provided to the face 20a of the back cover 20 when viewed from the Y2 direction side in a state in which the coin battery B is attached. Figure 9 As shown, the positive terminal 52 is disposed on the outside (Xl direction side) of the opening portion Al provided to the face 20a of the back cover 20 when viewed from the Y2 direction side. In addition, as shown in FIG. 2, the portion of the coin battery B on the positive terminal 52 side (Xl direction side) is disposed on the outside (Xl direction side) of the opening portion Al provided to the face 20a of the back cover 20 when viewed from the Y2 direction side in a state in which the coin battery B is attached.

[0086] As shown, the top end (end portion on the Yl direction side) of the protruding portion 31 is flat, and the top end of the protruding portion 31 presses the coin battery B from the Y2 direction side in a state in which the battery cover 30 is attached. Figure 9As shown, the travel area S is provided between the card slot portion 53 and the latch assembly portion 21. The travel area S is the area where the memory card C slides, and it is the area on the back side (the side in the Y2 direction) of the operation panel substrate 50 where electronic components EC and other components constituting electronic circuits are not installed (not actually installed).

[0087] Therefore, by sliding the memory card C from the travel area S towards the card slot 53 (X2 direction side), the user can insert the memory card C into the card slot 53. Furthermore, by sliding the memory card C from the card slot 53 towards the travel area S (X1 direction side), the user can remove the memory card C from the card slot 53.

[0088] In addition, in this embodiment, such as Figure 9 As shown, multiple (two) positive terminals 52 are provided along the outer peripheral surface P of the button cell B. Furthermore, the multiple positive terminals 52 are electrically connected to each other using a conductor pattern formed on the operation panel substrate 50.

[0089] Buckle assembly part 21 Figure 9 As shown, it is arranged along the outer peripheral surface P of the button cell B, and is configured to be able to flex and deform during the installation and removal of the button cell B.

[0090] like Figure 9 As shown, the snap-fit ​​assembly 21 includes a pair of arc-shaped arms 21a that are arc-shaped along the outer peripheral surface P of the button battery B and are elastically deformable.

[0091] In addition, such as Figure 9 As shown, the top ends of the pair of arc-shaped arms 21a of the snap-fit ​​assembly 21 are disposed on one side (X2 direction side) of the travel region S relative to the button battery B.

[0092] In addition, such as Figure 9 As shown, the snap-fit ​​assembly 21 includes a claw 21b located near the top end of a pair of arc-shaped arms 21a. The claw 21b is configured to cover (press) a portion of the button battery B from the Y2 direction side when the button battery B is installed in the area enclosed by the pair of arc-shaped arms 21a.

[0093] In addition, such as Figure 10 As shown, the back cover 20 includes an anti-entry portion 24 formed protruding toward the operation panel substrate 50 (Y1 direction side), which prevents the memory card C from entering between the back cover 20 and the operation panel substrate 50. Figure 9 As shown, the anti-entry section 24 is provided along the outer edge of the travel area S.

[0094] Additionally, it prevents the Y-direction gap D1 between the entry part 24 and the operation panel substrate 50 from (refer to) Figure 10width W (refer to FIG. 6) of the insertion port 53a of the card slot portion 53 in the Y direction for insertion of the memory card C. Figure 10 The interval Dl (refer to FIG. 6) in the Y direction between the entry prevention portion 24 and the operation panel substrate 50 is secured. Figure 10 The size for preventing the memory card C from entering between the back cover 20 and the operation panel substrate 50 is secured.

[0095] As shown in FIG. 6, the user, when installing the coin battery B, expands (deforms) the pair of arc-shaped arm portions 21a of the snap-fit portion 21 in a state in which the coin battery B is inclined with respect to the X direction along the face of the back side of the operation panel substrate 50 (in a state in which it is inclined), and installs the coin battery B. Figure 11 As shown in FIG. 6, the back cover 20 includes a deformation limiting portion 22 that limits the amount of deformation of the snap-fit portion 21 at the time of installation and removal of the coin battery B. The deformation limiting portion 22 is an arc-shaped wall that is formed (disposed) along the pair of arc-shaped arm portions 21a of the snap-fit portion 21.

[0096] Figure 11 As shown in FIG. 6, a positioning protrusion portion 21c is provided at the snap-fit portion 21 so as to position the coin battery B with respect to the positive terminal 52. The positioning protrusion portion 21c protrudes toward the side on which the coin battery B is disposed and the side on which the positive terminal 52 is disposed. Figure 12 Specifically, the positioning protrusion portion 21c is provided on the inner side of each of the pair of arc-shaped arm portions 21a. That is, one positioning protrusion portion 21c is provided with respect to one arm portion 21a. In addition, the positioning protrusion portion 21c is configured to protrude in an arc shape from the inner side of each of the pair of arc-shaped arm portions 21a toward the side of the coin battery B (the side of the negative terminal 51). In addition, the positioning protrusion portion 21c is provided on the operation panel substrate 50 side (the Yl direction side) with respect to the claw portion 21b. Furthermore, as shown in FIG. 6, the arm portion 21a, the positioning protrusion portion 21c, the deformation limiting portion 22, and the entry prevention portion 24 are formed continuously (integrally).

[0097] Figure 12 In addition, as shown in FIG. 6, an opening portion Al is provided at the back cover 20 in such a manner that the snap-fit portion 21 and the stroke region S are exposed. In addition, the opening portion Al is provided at the back cover 20 in such a manner that the deformation limiting portion 22 and the negative terminal 51 are exposed. The opening portion Al is formed in a stepped shape and is configured to expose the operation panel substrate 50 along the outer edges of the arm portion 21a, the positioning protrusion portion 21c, the deformation limiting portion 22, and the entry prevention portion 24.

[0098] In addition, as shown in FIG. 6, an opening portion Al is provided at the back cover 20 in such a manner that the snap-fit portion 21 and the stroke region S are exposed. In addition, the opening portion Al is provided at the back cover 20 in such a manner that the deformation limiting portion 22 and the negative terminal 51 are exposed. The opening portion Al is formed in a stepped shape and is configured to expose the operation panel substrate 50 along the outer edges of the arm portion 21a, the positioning protrusion portion 21c, the deformation limiting portion 22, and the entry prevention portion 24. Figure 12

[0099] In addition, as shown in FIG. 6, an opening portion Al is provided at the back cover 20 in such a manner that the snap-fit portion 21 and the stroke region S are exposed. In addition, the opening portion Al is provided at the back cover 20 in such a manner that the deformation limiting portion 22 and the negative terminal 51 are exposed. The opening portion Al is formed in a stepped shape and is configured to expose the operation panel substrate 50 along the outer edges of the arm portion 21a, the positioning protrusion portion 21c, the deformation limiting portion 22, and the entry prevention portion 24. Figure 12

[0100] In addition, as shown in FIG. 6, an opening portion Al is provided at the back cover 20 in such a manner that the snap-fit portion 21 and the stroke region S are exposed. In addition, the opening portion Al is provided at the back cover 20 in such a manner that the deformation limiting portion 22 and the negative terminal 51 are exposed. The opening portion Al is formed in a stepped shape and is configured to expose the operation panel substrate 50 along the outer edges of the arm portion 21a, the positioning protrusion portion 21c, the deformation limiting portion 22, and the entry prevention portion 24. Figure 13 ​​​​As shown, the negative terminal 51 is disposed at a position on the X2 direction side of the central portion of the position at which the coin battery B is disposed, with respect to the pair of arc-shaped arm portions 21a.

[0101] As shown, since the Y2 direction side of the positive terminal 52 is covered by the back cover 20, the user inserts (mounts) the coin battery B in the region surrounded by the pair of arc-shaped arm portions 21a in a state in which the coin battery B is inclined with respect to the X direction along the back side of the operation panel substrate 50 with the outer peripheral surface P on the X1 direction side facing the Y1 direction side (a state in which it is inclined, for example). Figure 14

[0102] Therefore, the negative terminal 51 is disposed at a position at which, even in the case in which the coin battery B is inserted (inserted obliquely) in the region surrounded by the pair of arc-shaped arm portions 21a in the inclined state, the positive electrode and the negative electrode of the coin battery B do not short circuit.

[0103] Specifically, the negative terminal 51 is disposed at a position offset to the X2 direction side from the central portion of the position at which the coin battery B is disposed, to a position at which, by causing the pair of arc-shaped arm portions 21a to interfere with the coin battery B, it is possible to increase the angle of inclination of the coin battery B with respect to the negative terminal 51 to an angle θ (refer to FIG. 6) at which both the positive electrode and the negative electrode of the coin battery B do not simultaneously contact the negative terminal 51. Figure 15

[0104] (Effects of the Present Embodiment)

[0105] In the present embodiment, the following effects can be obtained.

[0106] ​​In the present embodiment, the operation buttons 2 (switches 4) for performing operations on the power conversion device main body portion 102 are provided on the surface side (Y1 direction side) of the operation panel substrate 50. Also, the negative terminal 51 and the positive terminal 52 are provided on the back surface (Y2 direction side surface) of the operation panel substrate 50 in a manner corresponding to the button cell B. Thus, the button cell B can be mounted on the back surface (Y2 direction side surface) of the operation panel substrate 50 on which the negative terminal 51 and the positive terminal 52 are provided, and therefore, unlike the case where the button cell B is mounted on the surface side (Y1 direction side) of the operation panel substrate 50 on which the operation buttons 2 (switches 4) are provided, it is possible to suppress narrowing of the space on the side of the operation panel 101 on which the operation buttons 2 (switches 4) are provided. In addition, the opening portion Al provided in a manner that the battery cover 30 covering the snap-fit portion 21 is exposed is covered by the battery cover 30 that can be attached to and detached from the back surface cover 20, and therefore, the user can attach and detach (replace) the button cell B with respect to the snap-fit portion 21 for positioning the button cell B by detaching the battery cover 30. As a result, it is possible to provide the operation panel 101 and the power conversion device 100 that can mount the button cell B for supplying electric power to the operation panel 101 in a replaceable manner and suppress narrowing of the space on the side of the operation panel 101 on which the operation buttons 2 (switches 4) are provided.

[0107] In addition, in the present embodiment, as described above, the operation panel 101 main body is attached in a detachable manner with respect to the power conversion device main body portion 102. Thus, it is possible to easily attach and detach (replace) the button cell B with respect to the negative terminal 51 and the positive terminal 52 provided on the back surface (Y2 direction side surface) of the operation panel substrate 50.

[0108] In addition, in the present embodiment, as described above, the card slot portion 53 into which the memory card C is inserted is provided on the back surface (Y2 direction side surface) of the operation panel substrate 50, and therefore, it is possible to mount the memory card C on the back surface of the operation panel substrate 50 and cause the memory card C to store communication settings, communication logs, and the like between the power conversion device 100 and an external device. In addition, by providing the stroke region S for causing the memory card C to slide to thereby perform insertion into and extraction from the card slot portion 53 on the operation panel substrate 50, it is possible to easily perform insertion of the memory card C into the card slot portion 53 and extraction of the memory card C from the card slot portion 53. Also, by providing the opening portion Al of the back surface cover 20 in a manner that the snap-fit portion 21 and the stroke region S are exposed, it is possible to provide the battery cover 30 provided in a manner of covering the opening portion Al to be shared with respect to the snap-fit portion 21 and the stroke region S. As a result, it is possible to suppress an increase in the number of components and complication of the device structure.

[0109] Further, in the present embodiment, as described above, the stroke region S is provided between the card slot portion 53 and the snap-fit portion 21. Thus, unlike a case where the stroke region S is provided on the side opposite to the side on which the snap-fit portion 21 is provided with respect to the card slot portion 53, the snap-fit portion 21 and the stroke region S can be brought close to each other. Thus, the opening portion Al through which the snap-fit portion 21 and the stroke region S are exposed can be reduced. As a result, when the user performs work while detaching the battery cover 30 provided so as to cover the opening portion Al, entry of foreign matter into the inside of the operation panel 101 can be suppressed.

[0110] Further, in the present embodiment, as described above, the snap-fit portion 21 is configured to be elastically deformed at the time of attachment and detachment of the button cell B, and the back cover 20 includes the flexion restriction portion 22 that restricts the amount of elastic deformation of the snap-fit portion 21 at the time of attachment and detachment of the button cell B. Thus, the amount of elastic deformation of the snap-fit portion 21 can be restricted by the flexion restriction portion 22, and thus, at the time of attachment and detachment of the button cell B (replacement of the button cell B), breakage of the snap-fit portion 21 due to excessive flexion of the snap-fit portion 21 can be suppressed.

[0111] Further, in the present embodiment, as described above, the snap-fit portion 21 is provided so as to follow the outer circumferential surface P of the button cell B, and is configured to be elastically deformed at the time of attachment and detachment of the button cell B. Thus, since the snap-fit portion 21 is elastically deformed at the time of attachment and detachment of the button cell B, attachment and detachment of the button cell B (replacement of the button cell B) can be easily performed. Further, by providing the positioning protrusion portion 21c that protrudes toward the side on which the button cell B is disposed and the side on which the positive terminal 52 is disposed, to the snap-fit portion 21 provided so as to follow the outer circumferential surface P of the button cell B, the button cell B attached to the snap-fit portion 21 can be pressed toward the positive terminal 52. As a result, at the time of attachment of the button cell B, the button cell B and the positive terminal 52 can be brought into reliable contact.

[0112] Further, in the present embodiment, as described above, the snap-fit portion 21 includes a pair of arc-shaped arm portions 21a that are provided in an arc shape so as to follow the outer circumferential surface P of the button cell B and are elastically deformable, and the tips of the pair of arc-shaped arm portions 21a are disposed on the side on which the stroke region S is disposed (the X2 direction side) with respect to the button cell B. Thus, the user can easily spread the pair of arc-shaped arm portions 21a of the snap-fit portion 21 that are elastically deformable, from the side of the stroke region S, at the time of detachment of the button cell B. As a result, detachment of the button cell B can be easily performed.

[0113] In addition, in the present embodiment, as described above, the negative terminal 51 is disposed at a position closer to the tip end side of the pair of arc-shaped arm portions 21a than the central portion of the position at which the coin battery B is disposed, in the region surrounded by the pair of arc-shaped arm portions 21a. Thus, by disposing the negative terminal 51 at a position closer to the tip end side of the pair of arc-shaped arm portions 21a than the central portion of the position at which the coin battery B is disposed, as compared with the case where the negative terminal 51 is disposed at the central portion of the position at which the coin battery B is disposed, it is possible to dispose the negative terminal 51 at a position separate from the positive electrode provided at the outer peripheral surface P of the coin battery B. As a result, it is possible to prevent both the positive electrode and the negative electrode of the coin battery B from coming into contact with the negative terminal 51 and causing the positive electrode and the negative electrode of the coin battery B to short-circuit when mounting and dismounting (replacing) the coin battery B.

[0114] In addition, in the present embodiment, as described above, the positive terminal 52 is disposed on the outer peripheral surface P side of the coin battery B and is configured to be able to flexibly deform. Also, the back cover 20 includes a position restricting portion 23 that restricts the position of the outer peripheral surface P of the coin battery B with respect to the positive terminal 52, so as to restrict the amount of flexible deformation of the positive terminal 52. Thus, by the position restricting portion 23 that restricts the position of the outer peripheral surface P of the coin battery B with respect to the positive terminal 52, it is possible to restrict the amount of flexible deformation of the positive terminal 52 when mounting and dismounting (replacing) the coin battery B. As a result, it is possible to prevent the positive terminal 52 from being damaged due to excessive flexing of the positive terminal 52 when mounting and dismounting (replacing) the coin battery B.

[0115] In addition, in the present embodiment, as described above, the positive terminal 52 is provided in a plurality of (two) along the outer peripheral surface P of the coin battery B. Thus, since the positive terminal 52 is provided in a plurality of (two) along the outer peripheral surface P of the coin battery B, even in the case where the mounting position of the coin battery B has shifted on the operation panel substrate 50, it is possible to cause any one of the positive terminals 52 to come into contact with the coin battery B, unlike the case where only one positive terminal 52 is provided. As a result, as compared with the case where only one positive terminal 52 is provided, it is possible to reliably bring the coin battery B and the positive terminal 52 into contact.

[0116] Further, in the present embodiment, as described above, the back cover 20 includes the entry prevention portion 24 that is provided along the outer edge of the stroke region S in a manner that protrudes toward the operation panel substrate 50 side (Yl direction side) to prevent the memory card C from entering between the back cover 20 and the operation panel substrate 50. Thereby, in the stroke region S, at the time of insertion and extraction of the memory card C with respect to the card slot portion 53, it is possible to prevent the memory card C from entering between the back cover 20 and the operation panel substrate 50. As a result, it is possible to improve the workability at the time of insertion and extraction of the memory card C with respect to the card slot portion 53 for setting of communication between the power conversion device 100 and an external device, communication log, and the like.

[0117] Further, in the present embodiment, as described above, the battery cover 30 includes the protruding portion 31 that protrudes toward the negative terminal 51 side (Yl direction side) of the operation panel substrate 50 to press the coin battery B toward the negative terminal 51 side in a state where the battery cover 30 is attached to the back cover 20. Thereby, the coin battery B is pressed toward the negative terminal 51 side (Yl direction side) by the protruding portion 31 of the battery cover 30, and thus, it is possible to reliably bring the coin battery B and the negative terminal 51 into contact at the time of attachment of the coin battery B.

[0118] Further, in the present embodiment, as described above, the back side (Y2 direction side) of the operation panel 101 main body is attached to the control board 110 that accommodates the power conversion device main portion 102 and performs power control. Also, between the back cover 20 and the control board 110, the sealing member 40 is provided on the outside of the battery cover 30 in a manner that surrounds the battery cover 30. Thereby, with the sealing member 40 that is provided on the outside of the battery cover 30 in a manner that surrounds the battery cover 30 between the back cover 20 and the control board 110, it is possible to prevent water from entering between the back cover 20 and the control board 110 in a state where the back side (Y2 direction side) of the operation panel 101 main body is attached to the control board 110. As a result, it is possible to prevent water from entering between the back cover 20 and the battery cover 30 in a state where the back side (Y2 direction side) of the operation panel 101 main body is attached to the control board 110.

[0119] In addition, in the present embodiment, as described above, the battery cover 30 is disposed near the center of the surface 20a of the back cover 20 opposite the control panel 110. Also, the back cover 20 has a groove portion 25 formed near the outer periphery of the surface 20a of the back cover 20 opposite the control panel 110, into which the sealing member 40 is fitted. Thus, since the sealing member 40 is disposed near the outer periphery of the surface 20a of the back cover 20 opposite the control panel 110, the area of the surface 20a of the back cover 20 opposite the control panel 110, in which water can be prevented from entering between the back cover 20 and the control panel 110, can be made larger. In addition, by disposing the battery cover 30 near the center of the surface 20a of the back cover 20 opposite the control panel 110, as compared with the case in which the battery cover 30 is disposed near the outer periphery of the surface 20a of the back cover 20 opposite the control panel 110, the battery cover 30 can be easily surrounded by the sealing member 40. As a result, water can be easily prevented from entering between the back cover 20 and the battery cover 30.
