As illustrated in FIGS. 1 and 2, the housing 3 of the electronic device 1 has an appearance of a substantially quadrangular shape (a rectangular shape as an example, in the embodiment) when viewed from the front or the back thereof, for example, in the embodiment. The housing 3 is a rectangular parallelepiped that is thin and flat in the front and back direction (the thickness direction of the housing 3, the Z direction). The housing 3 comprises a face 3a (a front face, a front face portion) and a face 3b (a back face, a back face portion) located opposite the face 3a. The face 3a and the face 3b are provided substantially in parallel. The housing 3 comprises four ends 3c to 3f (sides, edges) and four corners 3g to 3j (pointed parts, bent portions, ends) viewed from the front. The ends 3c and 3e are examples of long sides. Ends 3d and 3f are examples of short sides.
The housing 3 comprises the wall 3k (a part, a plate, a frame, a front wall, a front face wall, a top wall) comprising the face 3a, and a wall 3m (a part, a plate, a back wall, a rear face wall, a bottom wall) comprising the face 3b. The walls 3k and 3m each have a quadrangular shape (a rectangular shape as an example, in the embodiment). The housing 3 comprises four walls 3n (a part, a plate, a side wall, an end wall, a standing wall, a surrounding part) each comprising a face 3p (a side surface, a surrounding surface) across the wall 3k and the wall 3m. An opening 3r in a quadrangular shape is provided on the wall 3k, for example.
In the present embodiment, as illustrated in FIG. 3, the housing 3 comprises a wall 3s, for example. The wall 3s is located between the wall 3k and the wall 3m and is provided facing inside the housing 3. The wall 3s is provided substantially in parallel with the wall 3k and the wall 3m. The thickness direction of the wall 3s is substantially the same as the thickness direction of the housing 3. The wall 3s comprises faces 3sa and 3sb. The face 3sa faces one side. The face 3sb is provided opposite the face 3sa and faces the other side. The wall 3s comprises a support 3sc (amounting part) on which a module 20 is mounted. The structure of the support 3sc will be described in detail later. The wall 3s is an example of a first wall. In FIG. 3, one side of the thickness direction of the wall 3s (the direction along the direction Z) is indicated by the arrow A1, and the other side of the thickness direction of the wall 3s is indicated by the arrow A2. In the descriptions below, unless otherwise specified, the one side refers to the one side of the thickness direction of the wall 3s and the other side refers to the other side of the thickness direction of the wall 3s.
The housing 3 can comprise a plurality of components (segments) combined together. The housing 3 comprises a first member 3Fr (a front side member, a cover, a bezel, a frame) comprising at least the wall 3k, a second member 3Rr (a back side member, a base, a bottom, a plate) comprising at least the wall 3m, and a third member 3Md (an intermediate member, a plate, an intermediate wall, an inner wall, a middle plate, a middle frame) comprising at least the wall 3s.
The first member 3Fr is made of a synthetic resin material (an electric insulating material), for example. The second member 3Rr and the third member 3Md are made of a metallic material, for example, in the present embodiment. According to the present embodiment, weight saving and improvement of stiffness and strength of the housing 3 therefore are easily obtained at the same time. The combination of these materials (quality of materials) is only an example, and therefore combination of other materials can be used. For example, the second member 3Rr and the third member 3Md can also be made of a synthetic resin material.

As illustrated in FIGS. 7 and 8, in the faces 21a and 21b, electrode pads 21j and 21k for grounding (a conductive portion, a grounding part, an electrode) are provided, respectively. The electrode pads 21j and 21k are each provided in the periphery of the opening 21i along the opening 21i. The electrode pads 21j and 21k each have a belted arc-shape extending along the opening 21i. The electrode pad 21k is larger than the electrode pad 21j. The electrode pad 21k has the width of its intermediate part larger than the width of each of the ends thereof. The circuit board 21 is an example of a third wall and the opening 21i is an example of a third opening.
As illustrated in FIGS. 3 and 4, the electronic component 22 is mounted on the face 21a. The outer shape of the electronic component 22 when viewed from the front is smaller than that of the circuit board 21 when viewed from the front. The electronic component 22 comprises a body 22a (an outer shell, a housing, a frame). The body 22a has a rectangular parallelepiped shape. Various components (members) are embedded in the body 22a.
The following describes the mounting structure of the module 20. As illustrated in FIG. 3, the end 21d of the module 20 is combined with the support 3sc by a mounting member 40, and the end 21f (the connector 21h) of the module 20 is combined with the connector 30. The circuit board 21 and a boss 3sd are provided side by side in the direction along the face 3sa.
As illustrated in FIGS. 9 and 10, the support 3sc protrudes from the face 3sa of the wall 3s to the one side (in the thickness direction of the wall 3s). The support 3sc comprises the boss 3sd, a base 3se, a regulator 3sf, and a catch portion 3sg.
The boss 3sd protrudes from the face 3sa (the wall 3s) to the one side (in the thickness direction of the wall 3s). The boss 3sd has a cylindrical shape (e.g., cylinder) extending in the thickness direction of the wall 3s. In the boss 3sd, an opening 3sh is provided. The opening 3sh opens at least toward the one side and along the thickness direction of the wall 3s. In the present embodiment, the opening 3sh opens to the one side and the other side in the thickness direction of the wall 3s along the thickness direction. The boss 3sd also comprises a female screw 3si. The female screw 3si surrounds at least a portion of the opening 3sh. That is, the female screw 3si has the opening 3sh. In the present embodiment, the female screw 3si is provided across an end face 3sj (an end, a tip end) at the one side of the boss 3sd and the face 3sb. The female screw 3si surrounds the entire opening 3sh. The boss 3sd is an example of a first base and the opening 3sh is an example of a first opening.
The base 3se is provided adjacent to the boss 3sd. The base 3se protrudes from the wall 3s to the one side (in the thickness direction of the wall 3s). The base 3se is located nearer to one side of the boss 3sd than to the end face 3sj at other side of the boss 3sd. That is, an end face ask at one side of the base 3se is located nearer to the other side of the boss 3sd than to the end face 3sj of the boss 3sd. The base 3se comprises a first part 3sm and a second part 3sn. The first part 3sm is connected to the boss 3sd and has a shape of surrounding a part of the regulator 3sf. The first part 3sm extends in the direction along the extending direction of the end 21d of the circuit board 21. The second part 3sn extends from the first part 3sm to the side opposite the boss 3sd. The width of the second part 3sn along the extending direction of the end 21d is smaller than the width of the first part 3sm along the extending direction of the end 21d. The first part 3sm and the second part 3sn contact the electrode pad 21k of the circuit board 21. The base 3se is an example of a second base.
The regulator 3sf protrudes from the base 3se to the one side (in the thickness direction of the wall 3s) and connected to the boss 3sd. In other words, the regulator 3sf bulges out from the boss 3sd toward the base 3se. An end face 3sp at one side of the regulator 3sf is connected to the end face 3sj of the boss 3sd. The end face 3sp and the end face 3sj constitute a planar end face 3sq at one side of the support 3sc. The regulator 3sf contacts a part 21m (the edge 21g) that faces the opening 21i in the circuit board 21, and regulates the movement of the module 20 toward the wall 3s. Specifically, the regulator 3sf regulates the relative movement between the wall 3s and the module 20 in the direction orthogonal to the thickness direction of the circuit board 21 (the thickness direction of the wall 3s). The regulator 3sf is an example of a first regulator.
The catch portion 3sg protrudes from the end face 3sp of the regulator 3sf to the one side (in the thickness direction of the wall 3s). The catch portion 3sg has a cylindrical shape, for example. The catch portion 3sg is an example of a first catch portion.
As illustrated in FIG. 3, the mounting member 40 is combined with the boss 3sd by a combining portion 41 such that the circuit board 21 is sandwiched between the mounting member 40 and the base 3se. As illustrated in FIGS. 11 and 12, the mounting member 40 comprises a wall 40a, a pair of regulators 40b, and a grip 40c. The mounting member 40 is made of a synthetic resin material or a metallic material (electrically conductive material), for example.
As illustrated in FIG. 3, the wall 40a extends from one side of the base 3se to one side of the boss 3sd. The wall 40a is placed over the end face 3sj of the boss 3sd. As illustrated in FIGS. 11 and 12, the wall 40a comprises faces 40d and 40e. The face 40d faces the one side and the face 40e is provided opposite the face 40d and faces the other side. The wall 40a comprises an opening 40f. The opening 40f penetrates the faces 40d and 40e. That is, the opening 40f penetrates the wall 40a in the thickness direction of the wall 40a. The opening 40f overlaps with the opening ash of the boss 3sd. The wall 40a is an example of a second wall and the opening 40f is an example of a second opening.
An catch portion 40g is provided on the wall 40a. The catch portion 40g is provided apart from the opening 40f. The catch portion 40g and the opening 40f are provided side by side along a first direction orthogonal to the thickness direction of the wall 40a (the direction represented with the arrow B1). An opening 40h is provided in the catch portion 40g. The opening 40h penetrates the faces 40d and 40e. The catch portion 40g faces the opening 40h. The catch portion 3sg of the support 3sc is located in the opening 40h. The catch portion 40g catches the catch portion 3sg, and regulates the movement of the mounting member 40 to the wall 3s in the direction orthogonal to the protruding direction of the catch portion 3sg (the thickness direction of the wall 3s). The catch portion 40g is an example of a second catch portion.
A contact portion 40i is provided on the face 40e (FIG. 12). The contact portion 40i is provided on the side of the catch portion 40g with respect to the opening 40f (the side of the catch portion 3sg). Specifically, the contact portion 40i is provided in the area comprising the part opposite the opening 40f side with respect to the catch portion 40g. The contact portion 40i has a belted circular-arc shape, for example, when viewed from the other side. The contact portion 40i contacts the electrode pad 21j of the circuit board 21.
The regulators 40b protrude from the face 40e to the other side. The regulators 40b extend from the face 40e of the wall 40a in a second direction (the direction represented with the arrow B2) orthogonal to the thickness direction of the wall 40a and the first direction. The regulators 40b extend in the opposite directions from each other. The regulators 40b face an end 21d (the edge 21g) of the circuit board 21. Any gap may exist between the regulators 40b and the end 21d. The regulators 40b contact the end 21d of the circuit board 21 (the edge 21g), and regulates the relative rotation of the mounting member 40 and the module 20. The regulators 40b are examples of a second regulator.
The grip 40c is provided on the part on the wall 40a opposite the catch portion 40g with respect to the opening 40f. A protruding portion 40j is provided on the grip 40c.
As illustrated in FIG. 3, the combining portion 41 penetrates through the opening 40f on the wall 40a and is inserted into the opening ash of the boss 3sd to combine the mounting member 40 and the boss 3sd together. Specifically, the combining portion 41 is an external female screw member and comprises a head 41a and a shaft 41b. The head 41a is located at the one side of the boss 3sd and placed over the face 40d of the wall 40a. The shaft 41b comprises the external female screw. The shaft 41b extends from the head 41a, penetrates through the opening 40f, and is inserted into the opening ash. Accordingly, the shaft 41b is combined with the female screw 3si. The wall 40a is sandwiched between the combining portion 41 and the boss 3sd. This operation combines the wall 40a and the boss 3sd. The diameter of the opening 40f on the wall 40a is larger than that of the shaft 41b of the combining portion 41 by a certain amount so that the form errors and the mounting errors can be absorbed. An end face 41c as a part of the head 41a on the one side is located nearer to the other side than an end face 22b as a part of the body 22a on the one side.
The following describes a mounting method of the module 20 in the electronic device 1. As illustrated in FIG. 6, the connector 21h of the circuit board 21 is connected to the connector 30 and the electrode pad 21k is placed over the base 3se so that the face 21a of the circuit board 21 faces the one side and the face 21b of the circuit board 21 faces the other side. On this occasion, the regulator 3sf contacts the part 21m of the circuit board 21 (the edge 21g). This operation regulates the relative movement between the wall 3s and the module 20 in the direction orthogonal to the thickness direction of the circuit board 21 (the thickness direction of the wall 3s).
Subsequently, as illustrated in FIG. 5, the mounting member 40 is moved so that the catch portion 3sg of the support 3sc relatively enters the opening 40f of the mounting member 40. The contact portion 40i of the mounting member 40 is placed over the face 21a of the circuit board 21 (the electrode pad 21j) and the face 40e of the mounting member 40 is placed over the end face 3sj of the boss 3sd. With this operation, the part around the opening 21i on the circuit board 21 is sandwiched between the base 3se and the wall 40a. On this occasion, the regulators 40b contact the edge 21g of the circuit board 21, thereby regulating the relative rotation of the mounting member 40 and the module 20.
Subsequently, as illustrated in FIG. 4, the mounting member 40 and the boss 3sd are combined with each other by the combining portion 41. Specifically, the combining portion 41 is inserted into the opening 40f and the opening 3sh from the side of a face 40ab rather than a face 40ac of the mounting member, and combines the combining portion 41 and the female screw 3si on the boss 3sd. With the above-described operations, the module 20 is mounted on the boss 3sd and the connector 30. This configuration causes the electrode pad 21k and the base 3se to contact with each other and electrically connects the module 20 and the wall 3s, whereby the module 20 is grounded.
As described above, in the mounting method according to the embodiment of the module 20 in the electronic device 1, the circuit board 21 of the module 20 is firstly located at one side of the base 3se; the mounting member 40 is located at one side the circuit board 21 and one side of the boss 3sd; and the circuit board 21 is sandwiched between the base 3se and the mounting member 40. After that, the mounting member 40 is combined with the boss 3sd by the combining portion 41. Here, the circuit board 21 is sandwiched between the mounting member 40 and the base 3se.
As described above, in the present embodiment, the module 20 is fixed to the wall 3s (the first wall) by the support 3sc, the mounting member 40, and the combining portion 41. The support 3sc comprises the boss 3sd (the first base) and the base 3se (the second base). The boss 3sd protrudes from the wall 3s to the one side (in the thickness direction of the wall 3s). The base 3se is provided on the face 3sa (a part on the one side) on the wall 3s and located nearer to one side of the boss 3sd than to the end face 3sj at other side of the boss 3sd. Here, the one side of the boss 3sd is located nearer to the wall 3s. The wall 40a (the second wall) of the mounting member 40 extends from one side of the base 3se to the other side of the boss 3sd. On the wall 40a, the opening 40f (the second opening) is provided. The opening 40f overlaps with the opening 3sh (the first opening) of the boss 3sd. The circuit board 21 (the third wall) of the module 20 is sandwiched between the base 3se and the wall 40a. The combining portion 41 penetrates through the opening 40f and is inserted into the opening ash, and combines the mounting member 40 and the boss 3sd together. This operation locates the face 21b of the circuit board 21 nearer to the other side than to the end face 3sj of the boss 3sd, thereby readily achieving a reduction of the thickness of the housing 3 in comparison to the configuration in which the circuit board 21 is placed over the end face 3sj of the boss 3sd.
In the present embodiment, the regulator 3sf protrudes from the base 3se to the one side. The regulator 3sf contacts the part 21m that faces the opening 21i in the circuit board 21, thereby regulating the movement of the module 20 toward the wall 3s. This operation helps locating the module 20.
In the present embodiment, the catch portion 3sg (the first catch portion) and the catch portion 40g (the second catch portion) are provided. The catch portion 40g catches the catch portion 3sg, thereby regulating the movement of the mounting member 40 toward the wall 3s, that is, locating the mounting member 40.
In the present embodiment, the end face 41c at one side of the head 41a located farther from the wall 3s in the thickness direction of the wall 3s is located toward the wall 3s in the thickness direction of the wall 3s with respect to the end face 22b at one side of the body 22a located farther from the wall 3s. This configuration readily achieves a reduction of the thickness of the housing 3.
In the present embodiment, the circuit board 21 and the boss 3sd are provided side by side in the direction along the face 3sa on the one side of the wall 3s. This configuration readily achieves a reduction of the thickness of the housing 3.
In the present embodiment, the connector 30 is housed in the housing 3 and combined with the part (the end 21f) of the circuit board 21 opposite the mounting member 40. This configuration supports both the ends 21d and 21f on the circuit board 21 that opposes each other. This configuration facilitates a stable mounting of the module 20.
In the present embodiment, the regulators 40b contact the edge 21g of the circuit board 21, and regulates the relative rotation of the mounting member 40 and the module 20. This operation helps installing the mounting member 40. This operation also facilitates a stable mounting of the module 20 because the rotation of the mounted module 20 is regulated.
In the present embodiment, the base 3se protrudes from the wall 3s to the one side (in the thickness direction of the wall 3s). This configuration separates the parts other than the part placed over the base 3se on the circuit board 21 from the wall 3s.
The structures and the shapes of the embodiments can be partially substituted. Moreover, specifications (a structure, a type, a direction, a shape, a size, a length, a width, a thickness, a height, the number, an arrangement, a position, a material, and the like) of each of the structures and the shapes can be changed as appropriate.
