  Embodiments of an AC adapter and an electronic device will be described below with reference to the accompanying drawings.

  First, the configuration of the television 1 will be described with reference to the drawings. A television 1 illustrated in FIG. 1 is an example of an electronic device, and includes a television main body 2 and an AC adapter 3.

  The television main body 2 corresponds to an electronic device main body, and includes a main body 11 and a stand 12 as shown in FIGS. The main body 11 includes a display unit 21 (see FIG. 1) disposed on the front surface 11a, and a drive circuit and a display data generation circuit (both not shown) disposed in the housing of the main body unit 11. It is configured. Further, an adapter mounting portion 22 for mounting the AC adapter 3 is formed on the side surface 11c side of the main body portion 11.

  As shown in FIGS. 3 and 4, the adapter mounting portion 22 is composed of five wall surfaces 23 a to 23 e (hereinafter also referred to as “wall surface 23” when not distinguished), and an accommodation space in which an opening 22 b is formed on the side surface 11 c. 22a, and the AC adapter 3 can be accommodated in the accommodation space 22a. In addition, each wall surface 23a-23e is equivalent to a mounting surface.

  As shown in FIGS. 3 and 4, heat absorption plates 24 a to 24 e (hereinafter, also referred to as “heat absorption plate 24” when not distinguished) are provided on the respective wall surfaces 23 a to 23 e. The heat absorbing plate 24 is an example of a heat absorbing portion provided separately from the television main body 2 (electronic device main body), and absorbs heat radiated (dissipated) from heat radiating plates 33a to 33e described later in the AC adapter 3. It has a function of conducting heat to the TV main body 2 side. As an example, the heat absorbing plate 24 is made of a plate material (metal plate) made of a metal having high thermal conductivity such as aluminum or copper. Further, a connector 25 to which a connector 37 described later in the AC adapter 3 is connected is disposed on the wall surface 23e (the wall surface 23 located on the back side of the accommodation space 22a).

  In the television 1, as shown in FIGS. 1 and 2, a vent 11d is formed in the housing of the main body 11 of the television main body 2, and is generated from a drive circuit and a display data generation circuit disposed in the housing. The heat of the AC adapter 3 absorbed through the heat absorbing plate 24 of the adapter mounting portion 22 is radiated from the vent 11d to the outside of the television main body 2.

  The AC adapter 3 includes, as an example, a rectifier circuit and a transformer (both not shown), and performs conversion processing for converting AC power supplied from an AC power source (not shown) into DC power by stepping down and rectifying the AC power. This is executed to supply DC power to the TV main body 2 (display unit 21, drive circuit, display data generation circuit, etc.). 5 and 6, the AC adapter 3 is formed in a rectangular parallelepiped shape that can be mounted on the adapter mounting portion 22 of the television main body 2.

  As shown in FIGS. 5 and 6, the main surfaces 31a and 31b of the AC adapter 3 (two surfaces having a large area among the six surfaces of the AC adapter 3) and the three side surfaces 31c to 31e 33a to 33e (hereinafter, also referred to as “radiating plate 33” when not distinguished) are provided. The heat radiating plate 33 is an example of a heat radiating section, and has a function of absorbing and radiating heat generated (conducted) from the main surfaces 31a and 31b and the side surfaces 31c to 31e generated from the AC adapter 3, The AC adapter 3 is provided separately from the housing. As an example, the heat radiating plate 33 is made of a plate material (metal plate) formed of a metal having high thermal conductivity such as aluminum or copper.

  Moreover, the resin film 34 is affixed (attached) to the surface (surface exposed outside) of the heat sinks 33a-33d. The resin film 34 is made of a resin having a small friction coefficient such as polypropylene (PP), polyethylene (PE), and polyethylene terephthalate (PET).

  In addition, a connector 37 connected to the connector 25 of the television main body 2 is disposed on the side surface 31e of the AC adapter 3 (the surface facing the wall surface 23e when mounted on the adapter mounting portion 22 of the television main body 2). Has been. Further, a power cord 35 having a plug 36 (see FIGS. 1 and 2) attached to the tip is disposed on the side surface 31f of the AC adapter 3. In this case, in the AC adapter 3, the side surface 31 e side can be inserted into the opening 22 b of the adapter mounting portion 22 and can be mounted by sliding on the adapter mounting portion 22.

  Next, a method for using the television 1 and an operation of the television 1 will be described with reference to the drawings.

  When the television 1 is used, the AC adapter 3 is attached to the adapter attachment portion 22 formed in the main body 11 of the television main body 2 as shown in FIGS. Specifically, the AC adapter 3 is inserted into the accommodating space 22a from the opening 22b (see FIGS. 3 and 4) of the adapter mounting portion 22 formed on the side surface 11c of the main body 11. At this time, the heat absorbing plates 24a to 24d (see both figures) provided on the wall surfaces 23a to 23d constituting the accommodating space 22a and the main surfaces 31a and 31b and the side surfaces 31c and 31d of the AC adapter 3 are provided. The AC adapter 3 is inserted into the accommodating space 22a while sliding in a state where the heat radiating plates 33a to 33d (see FIGS. 5 and 6) are opposed to each other.

  In this case, in this AC adapter 3, since the resin film 34 with a small friction coefficient is affixed on the surface of the heat sinks 33a to 33d, the heat absorbing plates 24a to 24d of the adapter mounting portion 22 are inserted when the AC adapter 3 is inserted. Even if the resin film 34 slides, the frictional resistance between the two is suppressed to a low level. For this reason, in this television 1, it is possible to smoothly insert the AC adapter 3 into the adapter mounting portion 22 (in the accommodation space 22a).

  Next, the AC adapter 3 is further inserted into the accommodation space 22a, whereby the connector 25 disposed on the wall surface 23e of the adapter mounting portion 22 and the connector 37 of the AC adapter 3 are connected. Thereby, as shown in FIG. 7, the AC adapter 3 is attached to the adapter attachment portion 22 of the television main body 2.

  Next, the plug 36 attached to the power cord 35 of the AC adapter 3 is connected to an AC power outlet (not shown). As a result, AC power is supplied to the AC adapter 3. In addition, the AC adapter 3 executes conversion processing to step down and rectify AC power to convert it into DC power, and supply DC power to the TV main body 2 (display unit 21, drive circuit, display data generation circuit, etc.). .

  Next, a power switch (not shown) in the TV main body 2 is operated. In response to this, the display data generation circuit of the television body 2 generates display data, and the display unit 21 displays an image based on the display data.

  On the other hand, heat is generated in the AC adapter 3 along with the conversion process, and the heat is conducted to the main surfaces 31 a and 31 b and the side surfaces 31 c to 31 e of the AC adapter 3. In this case, in the AC adapter 3, since the heat radiation plate 33 having high thermal conductivity is provided on each of the main surfaces 31a and 31b and each of the side surfaces 31c to 31e, the AC adapter 3 conducts to each of these surfaces 31a, 31b, and 31c to 31e. The conducted heat is conducted to each of the heat radiating plates 33a to 33e.

  Moreover, in this television 1, since each heat sink 24 with high heat conductivity is provided in each wall surface 23 which comprises the accommodation space 22a of the adapter mounting part 22 in which AC adapter 3 is mounted, each heat sink 33 Heat conducted to each heat absorbing plate 24 is conducted. That is, the heat generated inside the AC adapter 3 is radiated from each heat radiating plate 33 and absorbed by each heat absorbing plate 24 (conducted to the television main body 2).

  Further, the heat absorbed by each heat absorbing plate 24 is a vent hole 11d formed in the casing together with heat generated from a drive circuit and a display data generation circuit disposed in the casing of the main body 11 in the TV main body 2. The heat is dissipated from the TV body 2 to the outside. Thus, in this television 1, even in a structure in which each surface (two main surfaces 31a and 31b and three side surfaces 31c to 31e) of the AC adapter 3 is not exposed to the outside, The heat generated in is dissipated by the heat radiating plates 33 and radiated to the outside of the television 1 through the heat absorbing plates 24 in the accommodation space 22a, so that the heat radiation efficiency is sufficiently improved.

  As described above, according to the AC adapter 3 and the television 1, the AC facing the mounting surface of the adapter mounting portion 22 (the wall surface 23 constituting the accommodation space 22 a) when mounted on the adapter mounting portion 22 of the TV body 2. Since the heat sink 33 is provided on the main surfaces 31 a and 31 b of the adapter 3, the heat generated in the AC adapter 3 is conducted to the heat sink 33, and the television main body passes through the mounting surface of the adapter mounting portion 22 from the heat sink 33. 2 can dissipate heat. For this reason, according to the AC adapter 3 and the television 1, even if the main surface 31a, 31b of the AC adapter 3 is not exposed to the outside in the mounted state due to the structure of the adapter mounting portion 22, that is, Regardless of the structure, the heat generated by the AC adapter 3 can be reliably radiated. Therefore, according to the AC adapter 3 and the television 1, the heat radiation efficiency can be sufficiently improved and the structure of the adapter mounting portion 22 can be arbitrarily defined.

  In addition, according to the AC adapter 3 and the television 1, the AC adapter 3 is configured to be slidable with respect to the adapter mounting portion 22 of the television main body 2, thereby opening the opening 22 b only on one surface (one place). The AC adapter 3 can be easily mounted on the adapter mounting portion 22 having the above-described state, and the state in which the AC adapter 3 is mounted on the adapter mounting portion 22 having such a structure, that is, five of the six surfaces of the AC adapter 3 are Even in the state where it is not exposed to the outside, the heat generated by the AC adapter 3 can be reliably radiated.

  Moreover, according to this AC adapter 3 and the television 1, since the heat sink 33 was comprised with the metal plate, since the metal plate has high heat conductivity, heat dissipation efficiency can further be improved.

  Further, according to the AC adapter 3 and the television 1, the AC adapter 3 is attached to the adapter mounting portion 22 by attaching the resin film 34 to the surface of the heat radiating plate 33 facing the wall surface 23 constituting the adapter mounting portion 22. Since the frictional resistance with the wall surface 23 (the heat absorbing plate 24 provided on the wall surface 23) when mounting can be sufficiently reduced, the AC adapter 3 can be mounted on the adapter mounting portion 22 smoothly.

  Further, according to the television 1, the heat absorption plate 24 is provided on the wall surface 23 constituting the adapter mounting portion 22, thereby efficiently absorbing the heat radiated from the heat radiation plate 33 of the AC adapter 3 (the television main body 2). Heat conduction efficiency can be further improved.

  Note that the configurations of the AC adapter and the electronic device are not limited to the above configurations. For example, the television 101 illustrated in FIG. 8 can be employed. In the following description, the same components as those of the television 1 described above are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 8, the television 101 includes a television main body 102 and an AC adapter 103. An adapter mounting portion 122 for mounting the AC adapter 103 is formed in the main body portion 111 of the television main body 102. As shown in the figure, the adapter mounting portion 122 has a housing space 122a that is composed of five wall surfaces 123 and has an opening 122b formed in the back surface 111b. The AC adapter 103 is placed in the housing space 122a. It is configured to be accommodated.

  Further, as shown in FIG. 8, each wall surface 123 (mounting surface) is provided with a heat absorbing plate (heat absorbing portion) 124 made of, for example, a metal plate. Further, a connector 125 connected to a connector 137 described later in the AC adapter 103 is disposed on a wall surface parallel to the back surface 111b of each wall surface 123.

  As shown in FIG. 8, the AC adapter 103 is formed in a rectangular parallelepiped shape that can be attached to the adapter attachment portion 122 of the television main body 102. Further, the main surface 131 of the AC adapter 103 (one of the six surfaces of the AC adapter 103 having a large area) and the four side surfaces 132 have a heat radiating plate (heat radiating portion) made of, for example, a metal plate. 133 are provided. Moreover, the resin film 34 is affixed on the surface of each heat sink 133 except the heat sink 133 of the main surface 131 (illustration is abbreviate | omitted in the same figure).

  A connector 137 connected to the connector 125 of the television main body 102 is disposed on the main surface 131 of the AC adapter 103. Furthermore, a jack 138 to which a plug 136 attached to the power cord 35 is connected is disposed on the side surface 132 (the left side surface in the figure) of the AC adapter 103. In this case, the main surface 131 of the AC adapter 103 is opposed to a wall surface (corresponding to a mounting surface) parallel to the back surface 111 b of the main body 111 in the TV main body 102 among the wall surfaces 123 constituting the adapter mounting portion 122. In such a state, the adapter can be fitted and attached to the adapter attachment portion 122.

  According to the television 101 and the AC adapter 103, the AC adapter 103 can be fitted and mounted in a state where the main surface 131 faces the mounting surface of the adapter mounting portion 122 (a surface parallel to the back surface 111b of the TV main body 102). As a result, the AC adapter 103 can be easily attached to the adapter attachment portion 122 having the wide opening 122b equivalent to the main surface 131. Further, in a state where the adapter is mounted on the adapter mounting portion 122 having such a structure, heat generated in the AC adapter 103 is conducted to the heat radiating plate 133, and the mounting surface (provided on the mounting surface) of the adapter mounting portion 122 from the heat radiating plate 133. Heat can be reliably radiated to the television main body 102 via the heat absorbing plate 124).

  Moreover, as shown in FIGS. 9 and 10, a television 201 including a television main body 202 having an adapter mounting portion 222 and an AC adapter 203 can be employed. In this television 201, as shown in FIG. 9, instead of the plate-like heat absorbing plate 24 described above, heat absorbing fins 224 for absorbing heat are provided on each wall surface 223 (in this example, the adapter mounting portion 222). Four wall surfaces 223) are provided. Moreover, in this television 201, as shown in FIG. 10, it replaces with the above-mentioned plate-shaped heat sink 33, and the heat sink fin 233 is the main surface 231 of the AC adapter 203 (the area of the six surfaces of the AC adapter 203). Are provided on the two large surfaces) and the side surface 232 (in this example, the two side surfaces 232).

  In this case, each heat absorption fin 224 provided on two wall surfaces 223 parallel to the front surface 211a of the main body 211 in the TV main body 202 and each heat radiation fin 233 provided on each main surface 231 of the AC adapter 203 are mutually connected. The heat absorption fins 224 provided on the two wall surfaces 223 that are meshed with each other and the heat radiation fins 233 provided on the side surfaces 232 of the AC adapter 203 are configured to mesh with each other. Further, the heat absorbing fins 224 and the heat radiating fins 233 are made of a metal having high thermal conductivity (for example, aluminum or copper). Moreover, the resin film 34 is affixed on the surface of each radiation fin 233 (illustration is abbreviate | omitted in FIG. 10).

  In this case, in the television 201, the AC adapter 103 is slid and attached to the adapter attachment portion 122 while the heat absorbing fins 224 and the heat radiating fins 233 are engaged with each other. For this reason, the heat absorption fins 224 and the heat radiation fins 233 are configured such that each fin extends along the sliding direction of the AC adapter 103.

  In the television 201, the heat absorbing fins 224 and the heat radiating fins 233 are engaged with each other in a state where the AC adapter 203 is mounted on the adapter mounting portion 222. For this reason, in this structure, since the contact area of the heat absorption fin 224 and the heat radiation fin 233 can be enlarged sufficiently, the heat radiation efficiency can be further improved.

  Further, in place of the heat absorption plate 124 of the adapter mounting portion 122 in the television 101 described above, a heat absorption fin similar to the heat absorption fin 224 is provided, and in addition to the heat dissipation fin 233 instead of the heat dissipation plate 133 of the AC adapter 103 described above.

It can also be adopted. Moreover, it can replace with the heat absorption fin 224 and the heat radiation fin 233 which were formed with the metal, and can also employ | adopt the heat absorption fin and the heat radiation fin which were formed with the series cone type material. Furthermore, although the configuration example in which the resin film 34 is attached (attached) to the surfaces of the heat radiation plates 33 and 133 and the heat radiation fins 233 has been described above, a configuration in which the resin film 34 is not attached may be employed.
