[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-153981 Summary of the Invention [Problem to be solved by the invention]
[0004] In the above-mentioned electrical equipment unit, since the mounting components cannot be mounted at the positions on the mounting surface of the board where the support parts of the case member and the cover member are in contact, the arrangement of the mounting components on the mounting surface is restricted, and the degree of freedom of arrangement is reduced.

[0009] Hereinafter, embodiments of the electrical equipment unit and the indoor unit disclosed in the present application will be described in detail with reference to the drawings. Note that the electrical equipment unit and the indoor unit disclosed in the present application are not limited to the following embodiments. EXAMPLES
[0010] (Electrical equipment unit configuration) Fig. 1 is a plan view of an electric equipment unit according to an embodiment. Fig. 2 is an enlarged side view of the plug-in side of the electric equipment unit according to an embodiment. Fig. 3 is a plan view of the electric equipment unit according to an embodiment, showing a state in which a board is housed in a case member and a state in which a cover member is removed from the case member housing the board.
[0011] As shown in Figures 1, 2 and 3, the electrical equipment unit 1 of the embodiment includes a plurality of mounting components 5 including a first mounting component 5A and a second mounting component 5B, a board 6 having a mounting surface 6a on which the plurality of mounting components 5 are mounted, a case member 7 in which the board 6 is housed, and a cover member 8 attached to the case member 7 so as to cover the mounting surface 6a side of the board 6.
[0012] The cover member 8 of the electrical equipment unit 1 has a movement restricting portion 11 that restricts movement of the first mounting component 5A in a direction intersecting (in this embodiment, a direction perpendicular to) the mounting surface 6a of the board 6. In this embodiment, the movement restricting portion 11 restricts movement of the first mounting component 5A in a direction (Z direction) perpendicular to the mounting surface 6a of the board 6, thereby restricting movement of the board 6, to which the first mounting component 5A is fixed on the mounting surface 6a, in the thickness direction of the board 6 (direction perpendicular to the mounting surface 6a) within the case member 7.
[0013] 1, when the electrical component unit 1 is viewed from the mounting surface 6a side of the substrate 6, the length direction (longitudinal direction) of the electrical component unit 1 is indicated as X, the width direction (short side direction) of the electrical component unit 1 is indicated as Y, and the height direction (direction perpendicular to the paper surface of FIG. 1) of the electrical component unit 1 is indicated as Z, and is shown in each drawing. The electrical component unit 1 of the embodiment is provided, for example, in an indoor unit 3 (see FIG. 10) described below that constitutes an air conditioner (not shown).
[0014] (substrate) Fig. 4 is a plan view showing the board 6 in the electrical equipment unit 1 of the embodiment. As shown in Fig. 4, the board 6 is a printed circuit board on which a plurality of mounting components 5 are surface-mounted. In the longitudinal direction (X direction) of the board 6, a first mounting component 5A is mounted on one end side of a mounting surface 6a, and a second mounting component 5B is mounted on the other end side of the mounting surface 6a.
[0015] In this embodiment, a single-sided mounting board 6 is used, but a double-sided mounting board may be used. Regardless of whether the board is single-sided or double-sided mounting, the cover member 8 is attached to the case member 7 so as to cover the mounting surface 6a side on which the first mounting component 5A, whose movement is restricted by the cover member 8, is mounted.
[0016] Further, a first notch 6g and a second notch 6h are formed on the outer periphery of the mounting surface 6a of the substrate 6. The first notch 6g and the second notch 6h are formed on the outer periphery of both sides of the substrate 6 in the short side direction (Y direction).
[0017] 2, the first mounting component 5A has an electrically functioning functional part 13 and an outer part 14 surrounding the functional part 13 (see FIG. 9). The movement restricting part 11 of the cover member 8 restricts the movement of the outer part 14 of the first mounting component 5A in a direction (Z direction) perpendicular to the mounting surface 6a.
[0018] A female connection terminal 16 (hereinafter, sometimes simply referred to as connection terminal 16) is mounted on the mounting surface 6a of the board 6 in this embodiment as a first mounting component 5A, and a conductive part 18 in the connection terminal 16 that is electrically connected to a male connection terminal (attachment plug) 37a of a cable 37 (see FIG. 10) corresponds to the functional part 13. The connection terminal 16 is, for example, a USB (Universal Serial Bus) terminal. For this reason, the electrical equipment unit 1 in this embodiment is provided with an outlet 20 that exposes the end face of the connection terminal 16 on the side where the male connection terminal 37a is connected to the outside of the electrical equipment unit 1.
[0019] The outer casing 14 further provided on the connection terminal 16 is formed of a metal material into a cylindrical shape with a square cross section so that the plug-in port 20 side of the connection terminal 16 is open to the outside. When viewed from the plug-in port 20 side as in Fig. 2, the outer casing 14 has an upper surface portion 14a as a first outer surface portion, a lower surface portion 14b fixed to the mounting surface 6a of the substrate 6, a left side surface portion 14c, and a right side surface portion 14d.
[0020] The top surface portion 14a is formed so as to conform to the mounting surface 6a of the substrate 6 when the connection terminal 16 is mounted on the substrate 6, and is disposed so as to face a restricting surface 11a (described later) of the movement restricting portion 11. The conductive portion 18 serving as the functional portion 13 provided inside the outer shell portion 14 is provided away from the top surface portion 14a of the outer shell portion 14 in the Z direction. For this reason, even if a force is applied to the top surface portion 14a of the outer shell portion 14 by the movement restricting portion 11, the force is prevented from being applied to the conductive portion 18 from the top surface portion 14a, preventing damage to the conductive portion 18 and improving the operational reliability of the connection terminal 16.
[0021] The first mounting component 5A is not limited to the connection terminal 16, and may be, for example, a computing element such as a CPU (Central Processing Unit) or a storage element such as a memory. In the case of a CPU, a semiconductor chip on which a computing circuit is formed corresponds to the functional unit 13, and an exterior covering the computing circuit corresponds to the outer shell 14.
[0022] The board 6 of this embodiment is provided with a communication module 17 as a second mounted component 5B. The second mounted component 5B has a display unit 22 that displays information about the second mounted component 5B. The display unit 22 is, for example, a label attached to the exterior of the communication module 17, and is provided at a position where it can be confirmed when the second mounted component 5B is viewed from the mounting surface 6a side as shown in Figs. 1 and 2. The display unit 22 is not limited to a label, and may be printed on the exterior of the communication module 17.
[0023] The information displayed on the label is identification information unique to the communication module 17 for connecting the communication module 17 to a router via a wireless LAN (Local Area Network), for example, a service set identifier (SSID) for a Wi-Fi connection. The information on the label also includes a two-dimensional code (QR code (registered trademark)) for setting up a Wi-Fi connection. However, the information displayed on the label is not limited to this.
[0024] 2, the height H of the first mounting component 5A from the mounting surface 6a of the substrate 6 is the highest among the multiple mounting components 5. That is, in this embodiment, the height H of the first mounting component 5A from the mounting surface 6a is higher than the height of the second mounting component 5B from the mounting surface 6a. The height H of the first mounting component 5A refers to the distance from the mounting surface 6a to the upper surface of the upper surface portion 14a of the outer casing 14 in the thickness direction (Z direction) of the substrate 6. The height of the second mounting component 5B refers to the distance from the mounting surface 6a to the upper surface of the exterior of the second mounting component 5B in the thickness direction (Z direction) of the substrate 6.
[0025] By setting the height H of the first mounting component 5A in this manner, the movement restriction portion 11, which restricts the movement of the first mounting component 5A in the direction perpendicular to the mounting surface 6a (Z direction), is prevented from coming into contact with mounting components 5 other than the first mounting component 5A, i.e., the second mounting component 5B, and damage to the second mounting component 5B by the movement restriction portion 11 is prevented.
[0026] (Case material) Fig. 5 is a plan view showing the case member 7 in the electric component unit 1 of the embodiment. Fig. 6 is a side view showing the case member 7 in the electric component unit 1 of the embodiment.
[0027] 5 and 6, the case member 7 has an accommodation portion 7a in which the board 6 is accommodated. A peripheral wall 7b is formed in the case member 7 so as to surround the outer periphery of the board 6 accommodated in the accommodation portion 7a. An opening 7c is formed in the peripheral wall 7b of the case member 7 on the first mounting component 5A side of the board 6 accommodated in the accommodation portion 7a, the opening forming a part of the insertion port 20 of the connection terminal 16 serving as the first mounting component 5A.
[0028] 2, the rectangular plug-in port 20 is formed by the opening 7c of the case member 7 and the movement restricting portion 11 of the cover member 8. Therefore, by having the cover member 8 serve as a part of the plug-in port 20, the structure of the mold for forming the plug-in port 20 can be simplified, and the plug-in port 20 can be easily formed.
[0029] On the opening 7c side in the housing portion 7a, a positioning wall 7d for positioning the connection terminal 16 when the board 6 is housed in the housing portion 7a is formed extending from the edge of the opening 7c. This allows the connection terminal 16 to be easily positioned with respect to the insertion port 20 when the board 6 is housed in the housing portion 7a. In addition, on the opening 7c side of the peripheral wall 7b of the case member 7, fitting holes 7e into which fitting claws 12a (described later) of the cover member 8 are fitted are formed on both sides of the opening 7c in the short side direction (Y direction) of the case member 7.
[0030] In addition, a first restricting protrusion 7g and a second restricting protrusion 7h are formed on the bottom surface of the housing 7a to restrict the movement of the substrate 6 housed in the housing 7a in a direction along the mounting surface 6a, i.e., on the XY plane. The first restricting protrusion 7g and the second restricting protrusion 7h are formed on both sides of the short side direction (Y direction) of the case member 7 in the housing 7a. Therefore, when the substrate 6 is housed in the housing 7a, the first notch 6g of the substrate 6 is engaged with the first restricting protrusion 7g of the case member 7, and the second notch 6h of the substrate 6 is engaged with the second restricting protrusion 7h of the case member 7. As a result, the substrate 6 housed in the housing 7a is restricted from moving in the X and Y directions, i.e., from moving in a direction along the mounting surface 6a (direction along the XY plane).
[0031] In addition, protrusions 7k are formed protruding from the bottom surface near the four corners of the bottom surface of the housing 7a, on which the back surface 6b of the substrate 6 opposite the mounting surface 6a is placed. Here, the lead terminals of the multiple mounting components 5 mounted on the mounting surface 6a of the substrate 6 are soldered and fixed to the substrate 6 while protruding toward the back surface 6b. By placing the substrate 6 accommodated in the housing 7a on the protrusions 7k, the soldered parts protruding from the back surface 6b of the substrate 6 are prevented from contacting the bottom surface of the housing 7a. This prevents the substrate 6 from rattling due to the soldered parts and the multiple mounting components 5 from being damaged by the soldered parts being pressed.
[0032] In addition, on the peripheral wall 7b in the housing section 7a, pressing claws 7m are formed on the second mounting component 5B side of the board 6 housed in the housing section 7a, for pressing the corners of the board 6 on the second mounting component 5B side from the mounting surface 6a side. By pressing the corners of the board 6 with the pressing claws 7m, the end of the board 6 on the second mounting component 5B side is restricted from moving in a direction perpendicular to the mounting surface 6a (Z direction). In this embodiment, the pressing claws 7m press only the positions of the corners of the board 6 on the mounting surface 6a, so the degree of freedom of arrangement of the mounting components 5 on the mounting surface 6a is not impaired.
[0033] Moreover, the electric equipment unit 1 of this embodiment is not limited to a structure in which the case member 7 has the pressing claw 7m. Instead of the pressing claw 7m, the electric equipment unit 1 may be provided with, for example, another cover member (not shown) having a movement restriction portion that restricts the movement of the second mounted component 5B in the direction (Z direction) perpendicular to the mounting surface 6a, similar to the cover member 8, or may be provided with a cover member 8 on which a second movement restriction portion (not shown) that restricts the movement of the second mounted component 5B is formed.
[0034] (Cover material) Fig. 7 is a plan view showing the cover member 8 in the electric component unit 1 of the embodiment. Fig. 8 is a side view showing the cover member 8 in the electric component unit 1 of the embodiment.
[0035] As shown in Figures 7 and 8, the cover member 8 has a plate-shaped movement restricting portion 11 that restricts the movement of the first mounting component 5A as described above, and a pair of mounting pieces 12 for attaching the cover member 8 to the case member 7.
[0036] Details of the movement restricting portion 11 will be described later. Each mounting piece 12 is formed on both sides of the movement restricting portion 11, and has a fitting claw 12a that fits into the fitting hole 7e of the case member 7. The cover member 8 is arranged to cover the first mounting component 5A of the board 6 accommodated in the case member 7, and is pressed into the case member 7 in the Z direction toward the board 6, whereby each mounting piece 12 is elastically deformed, and each fitting claw 12a fits into the fitting hole 7e of the case member 7.
[0037] (Main part of the electrical equipment unit) Fig. 9 is a vertical cross-sectional view showing a main part of the electrical equipment unit 1 of the embodiment. The features of the electrical equipment unit 1 of the embodiment include a cover member 8. As shown in Figs. 2 and 9, in the cover member 8, a plate-like portion along the mounting surface 6a of the board 6, i.e., a plate-like portion covering the upper surface 14a of the outer portion 14 of the first mounted component 5A, serves as a movement restricting portion 11 for restricting the movement of the first mounted component 5A. The movement restricting portion 11 is formed so as to cover the upper surface 14a of the outer portion 14 of the first mounted component 5A.
[0038] The movement regulating portion 11 has a regulating surface 11a that regulates the movement of the outer casing 14 of the first mounting component 5A in a direction perpendicular to the mounting surface 6a of the substrate 6, and when the cover member 8 is attached to the case member 7, the regulating surface 11a is a plane that faces the upper surface 14a of the outer casing 14 of the first mounting component 5A across a gap G, which will be described later.
[0039] Therefore, the movement of the first mounting component 5A is restricted by the restricting surface 11a of the movement restricting portion 11, and thus the movement of the board 6 in the thickness direction of the board 6, which is the direction perpendicular to the mounting surface 6a (Z direction), is restricted. Therefore, in order to restrict the movement of the board 6 in the thickness direction, the electrical component unit 1 can reduce the portion in contact with the mounting surface 6a, such as a support portion that supports the board accommodated in the case member by sandwiching it in the thickness direction of the board, and therefore the degree of freedom in arranging the mounting components 5 on the mounting surface 6a is increased.
[0040] Furthermore, in the first mounting component 5A, the movement of the outer casing 14 is restricted by the movement restricting portion 11, so that when the movement restricting portion 11 comes into contact with the outer casing 14, damage to the functional portion 13 surrounded by the outer casing 14 is prevented. Even when the cover member 8 is attached or when vibrations are applied to the electrical equipment unit 1, the movement restricting portion 11 comes into contact only with the outer casing 14, and direct application of force to the board 6 is avoided, so that damage to the circuits on the mounting surface 6a of the board 6 and the like can be prevented.
[0041] The restricting surface 11a of the movement restricting portion 11 and the upper surface portion 14a of the outer casing portion 14 of the first mounted component 15A face each other in the direction (Z direction) in which the movement of the first mounted component 5A is restricted, and are separated from each other via a gap G. This prevents the movement restricting portion 11 from coming into contact with the outer casing portion 14, making it difficult for the movement restricting portion 11 to apply force to the outer casing portion 14, thereby preventing damage to the first mounted component 5A.
[0042] The separation distance D between the movement restricting portion 11 and the outer casing 14 caused by the gap G is the distance at which the first mounting component 5A having the maximum dimension in the dimensional tolerance of the first mounting component 5A in the direction in which the movement of the first mounting component 5A is restricted (Z direction) comes into contact with the movement restricting portion 11. In other words, the separation distance D caused by the gap G is set based on the maximum dimension of the first mounting component 5A described above.
[0043] Only when the first mounting component 5A has a maximum dimension within the dimensional tolerance, the first mounting component 5A comes into contact with the restricting surface 11a, and when the first mounting component 5A has a dimension less than the maximum dimension, the first mounting component 5A comes into non-contact with the restricting surface 11a. Therefore, the first mounting component 5A is prevented from being pressed in the direction in which the movement is restricted by the restricting surface 11a of the movement restricting portion 11 (Z direction), and in the restricted state by the movement restricting portion 11, damage to the outer shell 14 and damage to the board 6 due to the force applied by the movement restricting portion 11 can be prevented, and the operational reliability of the first mounting component 5A can be ensured.
[0044] In addition, since the first mounting component 5A has the functional section 13 provided inside the outer casing 14 and spaced apart from the upper surface 14a of the outer casing 14 as described above, even if the restricting surface 11a of the movement restricting section 11 comes into contact with the upper surface 14a, the application of force from the upper surface 14a to the functional section 13 (conductive section 18) is avoided, preventing damage to the functional section 13 and improving the operational reliability of the first mounting component 5A (connection terminal 16). Furthermore, when the movement restricting section 11 comes into contact with the outer casing 14, the force applied to the outer casing 14 is dispersed by surface contact with the upper surface 14a without localized force being applied to the outer casing 14, so that damage to the first mounting component 5A by the movement restricting section 11 can be suppressed.
[0045] Moreover, the cover member 8 is formed so as to expose the display section 22 of the second mounted component 5B to the outside of the cover member 8 when attached to the case member 7. That is, as shown in FIG. 1, when the electric component unit 1 is viewed from the mounting surface 6a side of the board 6 with the cover member 8 attached to the case member 7, the display section 22 of the second mounted component 5B is exposed to the outside of the cover member 8. Therefore, the display section 22 of the second mounted component 5B can be easily confirmed from the outside of the electric component unit 1. Moreover, the manufacturing cost of the cover member 8 can be reduced compared to a structure in which the cover member 8 covers the entire mounting surface 6a side of the board 6.
[0046] (How to assemble the electrical equipment unit) A method of assembling the electrical equipment unit 1 configured as above will be described. First, in the process of assembling the electrical equipment unit 1, an operator inserts the board 6 into the housing portion 7a of the case member 7 from the end portion on the second mounting component 5B side below each of the pressing claws 7m. Next, the operator brings the end portion on the first mounting component 5A side of the board 6 close to the inside of the housing portion 7a, and engages the first restricting protrusion 7g in the housing portion 7a with the first notch 6g of the board 6, and engages the second restricting protrusion 7h in the housing portion 7a with the second notch 6h of the board 6. As a result, the board 6 is positioned in the housing portion 7a, and movement in the direction along the mounting surface 6a of the board 6 (direction along the XY plane) is restricted.
[0047] Next, the worker lowers the end of the board 6 on the side of the first mounting component 5A into the housing section 7a, positions the first mounting component 5A (connection terminal 16) with respect to the opening 7c (socket port 20) by abutting the outer casing 14 of the first mounting component 5A against the positioning wall 7d in the housing section 7a, and places the board 6 on each protrusion 7k in the housing section 7a. As a result, the board 6 is housed at a predetermined position in the housing section 7a with its movement in the directions (X direction and Y direction) along the mounting surface 6a restricted.
[0048] Next, the worker fits the fitting claws 12a of the mounting pieces 12 of the cover member 8 into the fitting holes 7e of the case member 7, thereby attaching the cover member 8 to the case member 7. As a result, the movement of the first mounting component 5A of the board 6 accommodated in the case member 7 in the direction perpendicular to the mounting surface 6a of the board 6 (Z direction) is restricted by the movement restricting portion 11 of the cover member 8. As a result, the movement of the board 6 to which the first mounting component 5A is fixed in the direction perpendicular to the mounting surface 6a (Z direction), i.e., in the thickness direction of the board 6, is restricted. In addition, in the electrical equipment unit 1, by attaching the cover member 8 to the case member 7, an insertion port 20 for the first mounting component 5A (connection terminal 16) is formed by the opening 7c of the peripheral wall 7b of the case member 7 and the movement restricting portion 11 of the cover member 8.
[0049] (indoor unit) A description will now be given of an indoor unit equipped with the above-mentioned electrical component unit 1. Fig. 10 is a perspective view for explaining the indoor unit of the embodiment.
[0050] As shown in Fig. 10, the indoor unit 3 of the embodiment includes a housing 31 that houses a blower fan 33 and a heat exchanger 34, and an electrical equipment unit 1. The housing 31 has a front cover 32 provided on a front surface 31F facing the indoor space, which is capable of opening and closing the inside of the housing 31. A control circuit section 36 that controls the motor of the blower fan 33, the electrical equipment unit 1, etc. is provided inside the housing 31. The control circuit section 36 has a cable 37 that is connected to a first mounted component 5A (connection terminal 16) of the electrical equipment unit 1, and an insertion plug 37a of the cable 37 is inserted into the first mounted component 5A (connection terminal 16) through an insertion port 20 of the electrical equipment unit 1.
[0051] The electrical equipment unit 1 is disposed at a lower part inside a front part 31F facing the interior space of the housing 31. The electrical equipment unit 1 is disposed so that a display unit 22 of a second mounted component 5B (communication module 17) faces the outside of the housing 31.
[0052] For this reason, a user of the indoor unit 3 can easily read the information on the display section 22 of the second mounted component 5B of the electrical component unit 1 from the front surface 31F side by opening the front cover 32 of the indoor unit 3. Furthermore, since workers can easily check the display section 22 of the electrical component unit 1 during the manufacturing process of the indoor unit 3, they can easily perform work such as attaching a label (not shown) on which information about the communication module 17 is printed to the housing 31.
[0053] (Effects of the embodiment) As described above, the electrical equipment unit 1 of the embodiment includes a plurality of mounting components 5 including the first mounting component 5A, a board 6 having a mounting surface 6a on which the plurality of mounting components 5 are mounted, a case member 7 in which the board 6 is housed, and a cover member 8 attached to the case member 7 so as to cover the mounting surface 6a side of the board 6. The cover member 8 has a movement restricting portion 11 that restricts movement of the first mounting component 5A in a direction intersecting the mounting surface 6a. In this manner, the movement of the first mounting component 5A is restricted by the movement restricting portion 11 of the cover member 8, so that the board 6 to which the first mounting component 5A is fixed is restricted from moving in the thickness direction (Z direction) of the board 6 within the case member 7. This allows the portion in contact with the mounting surface 6a to restrict the movement of the board 6 in the thickness direction to be reduced, thereby improving the degree of freedom in arranging the mounting components 5 on the board 6. This prevents the mounting surface 6a of the board 6 from becoming larger and the electrical equipment unit 1 from becoming larger.
[0054] Moreover, the first mounting component 5A in the electrical equipment unit 1 of the embodiment has a functional part 13 that functions electrically and an outer casing part 14 that surrounds the functional part 13, and the movement restricting part 11 of the cover member 8 restricts the movement of the outer casing part 14 of the first mounting component 5A. This prevents the functional part 13 surrounded by the outer casing part 14 from being damaged when the movement restricting part 11 comes into contact with the outer casing part 14. Furthermore, even when the cover member 8 is attached or when the electrical equipment unit 1 is subjected to vibration, the movement restricting part 11 comes into contact only with the outer casing part 14, preventing a force from being directly applied to the board 6, thereby preventing damage to the circuitry on the mounting surface 6a of the board 6.
[0055] In the electrical equipment unit 1 of the embodiment, the movement restricting portion 11 of the cover member 8 and the outer casing 14 of the first mounted component 5A are separated by a gap G. This prevents the movement restricting portion 11 from coming into contact with the outer casing 14, making it difficult for the movement restricting portion 11 to apply force to the outer casing 14, thereby preventing damage to the first mounted component 5A.
[0056] In the electric equipment unit 1 of the embodiment, the separation distance D between the movement restricting portion 11 and the outer casing 14 by the gap G is the distance at which the first mounting component 5A having the maximum dimension in the dimensional tolerance of the first mounting component 5A in the direction in which the movement of the first mounting component 5A is restricted (Z direction) comes into contact with the movement restricting portion 11. As a result, the first mounting component 5A comes into contact with the restricting surface 11a only when the first mounting component 5A has the maximum dimension within the dimensional tolerance, and the first mounting component 5A comes into non-contact with the restricting surface 11a when the first mounting component 5A has a dimension less than the maximum dimension. Therefore, the first mounting component 5A is prevented from being pressed in the direction in which the movement is restricted (Z direction) by the restricting surface 11a of the movement restricting portion 11, and in the restricted state by the movement restricting portion 11, damage to the outer casing 14 and damage to the board 6 due to the force applied by the movement restricting portion 11 are prevented, and the operational reliability of the first mounting component 5A can be ensured.
[0057] In the electric equipment unit 1 of the embodiment, the movement restricting portion 11 of the cover member 8 has a restricting surface 11a that restricts the movement of the outer casing portion 14 of the first mounting component 5A, and the outer casing portion 14 has an upper surface portion 14a that faces the restricting surface 11a of the movement restricting portion 11 and is aligned with the mounting surface 6a. In the first mounting component 5A, the functional portion 13 is provided away from the upper surface portion 14a of the outer casing portion 14. This prevents the upper surface portion 14a from applying force to the functional portion 13 (conductive portion 18) even if the movement restricting portion 11 comes into contact with the upper surface portion 14a of the outer casing portion 14, thereby preventing damage to the functional portion 13 and improving the operational reliability of the first mounting component 5A (connection terminal 16). Furthermore, when the movement restricting portion 11 comes into contact with the outer casing portion 14, the force applied to the outer casing portion 14 is distributed by making surface contact with the upper surface portion 14a without applying a local force to the outer casing portion 14, thereby preventing damage to the first mounted component 5A by the movement restricting portion 11.
[0058] In the electrical equipment unit 1 of the embodiment, the height H of the first mounted component 5A from the mounting surface 6a is the highest among the multiple mounted components 5. This prevents the movement restricting portion 11 from coming into contact with other mounted components 5 (e.g., the second mounted component 5B) than the first mounted component 5A, and prevents the movement restricting portion 11 from damaging the second mounted component 5B.
[0059] Moreover, in the electrical equipment unit 1 of the embodiment, the multiple mounting components 5 include a second mounting component 5B, and the second mounting component 5B has a display unit 22 that displays information about the second mounting component 5B. When the electrical equipment unit 1 is viewed from the mounting surface 6a side with the cover member 8 attached to the case member 7, the display unit 22 is exposed to the outside of the cover member 8. This allows the display unit 22 of the second mounting component 5B to be easily confirmed from the outside of the electrical equipment unit 1. Moreover, the manufacturing cost of the cover member 8 can be reduced compared to a structure in which the cover member 8 covers the entire mounting surface 6a side of the board 6.
[0060] Moreover, the electrical equipment unit 1 of the embodiment includes an outlet 20 that exposes an end face of the connection terminal 16 serving as the first mounted component 5A to the outside, and the outlet 20 is formed by the opening 7c of the case member 7 and the movement restricting portion 11 of the cover member 8. As a result, the cover member 8 serves as a part of the outlet 20, which simplifies the structure of the mold for forming the outlet 20 and makes it easy to form the outlet 20.
[0061] The indoor unit 3 of the embodiment includes a housing 31 that houses a blower fan 33 and a heat exchanger 34, and an electrical component unit 1, with the electrical component unit 1 disposed inside a front surface 31F of the housing 31 that faces the indoor space. This allows a user of the indoor unit 3 to easily read information on the display unit 22 of the second mounted component 5B of the electrical component unit 1 from the front surface 31F side. Also, during the manufacturing process of the indoor unit 3, workers can easily check the display unit 22 of the electrical component unit 1. [Explanation of symbols]
