[Figure 2] Figure 2 is a perspective view showing an electrical component unit of the electrical component support structure of the embodiment. [Figure 3] Figure 3 is a cross-sectional view showing the mounting portion of the electrical component support structure of the embodiment. [Figure 4] Figure 4 is a rear view showing the electrical component support structure of the embodiment. [Modes for carrying out the invention]

[0009] Hereinafter, embodiments for carrying out the invention (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiments described below. Furthermore, the components in the embodiments described below include those that are easily conceivable by those skilled in the art, those that are substantially the same, and those that fall within the so-called equivalent range. Moreover, the components disclosed in the embodiments described below can be combined as appropriate.

[0010] The electrical component support structures of the embodiments shown in Figures 1 to 4 are applied, for example, to electronic equipment 100 mounted inside the passenger compartment of a vehicle. The electronic equipment 100 is, for example, an AV (Audio Visual) integrated car navigation system. Here, in each figure, the X direction is the vertical direction, the Y direction is the horizontal direction, and the Z direction is the front-to-back direction.

[0011] As shown in Figures 1 to 4, the electrical component support structure of the embodiment includes an electrical component unit 1 and a mounting portion 2.

[0012] The electrical component unit 1 comprises an electrical component 1A, a flat wiring material 1B, a gripping portion 1C, a holding member 1D, and a reinforcing member 1E.

[0013] In this embodiment, the electrical component 1A is a microphone element. In this embodiment, the electrical component 1A as a microphone element is formed as a thin rectangular plate that is long in the left-right direction when viewed from the front-rear direction. As shown in Figure 2, the electrical component 1A has sound-collecting sections 1Aa at two locations on the front left and right sides. The electrical component 1A also has a recess 1Ab that constitutes a guide section. The recess 1Ab is formed by cutting out a rectangular shape at the center in the left-right direction at the upper end of the electrical component 1A. The recess 1Ab may also be formed at the center of the lower end of the electrical component 1A. Furthermore, the recess 1Ab may be formed at a position offset from the center of the upper or lower end of the electrical component 1A.

[0014] Flat wiring material 1B includes, for example, flexible printed circuits (FPCs) and flexible flat cables (FFCs). Flexible printed circuits are constructed by laminating conductive metal foil, such as copper, onto an insulating base film made of a thin, flexible polyimide or the like to form an electrical circuit. Flexible flat cables are constructed by sandwiching parallel-arranged conductors from above and below with a film-like insulator. As shown in Figures 1 and 2, the flat wiring material 1B is provided extending from one end of the electrical component 1A in the left-right direction. The flat wiring material 1B is provided bent to the rear from one end of the electrical component 1A in the left-right direction. The length of the flat wiring material 1B extending to the rear of the electrical component 1A is formed to be longer than the cylindrical depth of the wall portion 2B of the mounting portion 2, which will be described later. A reinforcing sheet 1Ba is attached to the flat wiring material 1B over a certain length range from the portion that extends from the electrical component 1A and is bent. The reinforcing sheet 1Ba causes the flat wiring material 1B to spread outwards in the left-right direction beyond the line L1 extending in the front-rear direction from the bent portion, and also provides elastic force in the left-right direction. In addition, the flat wiring material 1B is provided with a connection portion 1Bb for electrical connection at its extended end.

[0015] As shown in Figures 1 and 2, the gripping portion 1C is provided extending from a different part of the electrical component 1A than the flat wiring material 1B. In this embodiment, the gripping portion 1C is provided extending from the other end of the electrical component 1A in the left-right direction. Therefore, the gripping portion 1C is provided extending from the end of the flat wiring material 1B opposite to the end extending from the electrical component 1A. The gripping portion 1C is provided by bending it to the rear from the other end of the electrical component 1A in the left-right direction. Therefore, the gripping portion 1C is provided by bending it in the same direction as the flat wiring material 1B. The length of the gripping portion 1C extending to the rear of the electrical component 1A is formed to be longer than the cylindrical depth of the wall portion 2B of the mounting portion 2, which will be described later. A reinforcing sheet 1Ca is attached to the gripping portion 1C from the portion that extends from the electrical component 1A and is bent to the tip. The reinforcing sheet 1Ca causes the gripping portion 1C to spread outward in the left-right direction beyond the line L2 extending in the front-rear direction from the bent portion, and also provides elastic force in the left-right direction. The gripping portion 1C has the same configuration as the flat wiring material 1B. That is, the gripping portion 1C is made of a flat wiring material that extends from a different part of the electrical component 1A than the flat wiring material 1B.

[0016] The retaining member 1D is used to attach the electrical component 1A to the mounting portion 2. In this embodiment, the retaining member 1D is made of an adhesive sheet. As shown in Figure 2, the retaining member 1D is formed to be smaller than the shape of the front surface of the electrical component 1A and is attached to the front surface of the electrical component 1A. The retaining member 1D has an adhesive surface 1Da on its front surface. The retaining member 1D has a through hole 1Db that exposes the sound collection portion 1Aa of the electrical component 1A to the front. In addition, the retaining member 1D is provided with a rectangular notch 1Dc to avoid the recess 1Ab of the electrical component 1A in the arrangement described above.

[0017] The reinforcing member 1E is made of, for example, PET resin and reinforces the electrical component 1A. As shown in Figure 1, the reinforcing member 1E is formed to be smaller than the shape of the rear surface of the electrical component 1A and is attached to the rear surface of the electrical component 1A. The reinforcing member 1E has an opening 1Ea to avoid interference with the sound-collecting part 1Aa of the electrical component 1A. In addition, the reinforcing member 1E is provided with a rectangular notch 1Eb to avoid the recess 1Ab of the electrical component 1A as described above.

[0018] In the case of the electronic device 100, the attachment portion 2 is provided, for example, on the front panel. As shown in FIGS. 1, 3, and 4, the attachment portion 2 has a holding portion 2A, a wall portion 2B, and a convex portion 2C.

[0019] The holding portion 2A is a plate-like member arranged along the upper, lower, left, and right planes. The holding portion 2A holds the electric component unit 1 by attaching a holding member 1D made of an adhesive sheet to its rear surface. Therefore, the holding portion 2A holds the electric component 1A. Further, a through hole 2Aa penetrating in the front-rear direction is formed in the holding portion 2A to allow sound to reach the sound collecting portion 1Aa of the electric component 1A.

[0020] The wall portion 2B surrounds the holding portion 2A and is provided to extend to the rear side of the holding portion 2A. The wall portion 2B includes left and right wall portions 2Ba surrounding the left and right of the holding portion 2A and upper and lower wall portions 2Bb surrounding the upper and lower of the holding portion 2A. Therefore, the wall portion 2B is formed in a rectangular cylindrical shape extending to the rear side in the upper, lower, left, and right directions of the holding portion 2A. Then, the electric component unit 1 is inserted into the inner part of the cylindrical wall portion 2B from the rear side of the holding portion 2A and is attached and held by the holding portion 2A.

[0021] The protrusion 2C protrudes inward in the cylindrical shape of the wall portion 2B, is located behind the holding portion 2A, and extends in the cylindrical depth direction of the wall portion 2B. In this embodiment, the protrusion 2C is located in the center in the left-right direction of the upper wall portion 2Bb. The recess 1Ab of the electrical component 1A engages with the protrusion 2C. Therefore, the protrusion 2C and the recess 1Ab function as guides that guide the electrical component unit 1 to the holding portion 2A until the electrical component unit 1 is inserted into the cylindrical depth of the wall portion 2B and moved to and attached to the holding portion 2A. Furthermore, the protrusion 2C is formed so that its left-right dimensions gradually increase from the rear towards the holding portion 2A. The gap for engagement between the recess 1Ab and the protrusion 2C is smallest at the position where it reaches the holding portion 2A. Therefore, when guiding the electrical component unit 1 to the holding portion 2A, the convex portion 2C and the concave portion 1Ab are positioned so that the sound-collecting portion 1Aa of the electrical component 1A aligns with the through-hole 2Aa of the holding portion 2A. The convex portion 2C is provided in accordance with the above-described arrangement of the concave portion 1Ab of the electrical component 1A. For example, if the concave portion 1Ab is formed at the lower end of the electrical component 1A, the convex portion 2C is provided at the lower wall portion 2Bb of the wall portion 2B.

[0022] As described above, the electrical component unit 1 is held by the holding portion 2A of the mounting portion 2. The cylindrical shape of the wall portion 2B into which the electrical component unit 1 is inserted is not large enough for the fingers of the operator assembling it to fit inside. Therefore, when attaching the electrical component unit 1 to the mounting portion 2, the operator holds the flat wiring member 1B and the gripping portion 1C with the fingers of each hand and inserts them into the cylindrical shape of the wall portion 2B toward the holding portion 2A so that the concave portion 1Ab is aligned with the convex portion 2C. In such an attachment operation, in the case of an electrical component unit without the gripping portion 1C, the left and right ends are displaced in the front-rear direction due to the deflection of the flat wiring member 1B, making it difficult to position the sound collecting portion 1Aa of the electrical component 1A at an appropriate holding position that aligns with the through hole 2Aa of the holding portion 2A. In this regard, the electrical component support structure of the embodiment can easily position and hold the electrical component 1A at an appropriate holding position where the position of the sound collecting portion 1Aa of the electrical component 1A aligns with the through hole 2Aa of the holding portion 2A. Also, the electrical component unit 1 is biased so that the flat wiring member 1B and the gripping portion 1C are pressed against the wall portion 2B (left and right wall portions 2Ba) by the elastic force in the left-right direction while being held by the holding portion 2A. Therefore, the electrical component unit 1 is held inside the cylindrical shape of the wall portion 2B by the elastic forces of the flat wiring member 1B and the gripping portion 1C. Note that at least one of the flat wiring member 1B and the gripping portion 1C only needs to have an elastic force. In the unlikely event that the electrical component 1A of the electrical component unit 1 fails, the electrical component unit 1 can be easily removed from the holding portion 2A by pulling the flat wiring member 1B and the gripping portion 1C. When there is no gripping portion 1C, one side of the flat wiring member 1B will be pulled, and it will be difficult to remove the electrical component unit 1 because it will tilt.

[0023] Thus, the electrical component support structure of the embodiment includes a mounting portion 2 having a holding portion 2A and a cylindrical wall portion 2B surrounding the holding portion 2A, an electrical component 1A inserted into the inner part of the cylindrical shape of the wall portion 2B and held by the holding portion 2A, a flat wiring member 1B extending from the electrical component 1A, and an electrical component unit 1 having a gripping portion 1C extending from a portion different from the flat wiring member 1B.

[0024] This electrical component support structure allows the electrical component unit 1 to be easily positioned by inserting it into the cylindrical inner part of the wall portion 2B and holding the electrical component 1A in the holding portion 2A, thanks to the flat wiring material 1B and the gripping portion 1C. As a result, the electrical component support structure of this embodiment can improve the ease of installation when attaching the electrical component unit 1 to the mounting portion 2.

[0025] Furthermore, in the electrical component support structure of this embodiment, the gripping portion 1C is provided extending from the end of the flat wiring material 1B opposite to the end extending from the electrical component 1A.

[0026] With this electrical component support structure, the flat wiring material 1B and the gripping portion 1C can be held with the fingers of each hand, respectively, and the electrical component unit 1 can be inserted into the cylindrical rear part of the wall portion 2B, positioning the electrical component 1A to be held by the holding portion 2A. As a result, the electrical component support structure of this embodiment can further improve the ease of installation when attaching the electrical component unit 1 to the mounting portion 2.

[0027] Furthermore, in the electrical component support structure of this embodiment, the gripping portion 1C has the same configuration as the flat wiring material 1B.

[0028] According to this electrical component support structure, the gripping portion 1C can be constructed using flat wiring material 1B. As a result, the electrical component support structure of this embodiment can improve the manufacturability of the electrical component unit 1.

[0029] Furthermore, in the electrical component support structure of this embodiment, at least one of the gripping portion 1C and the flat wiring material 1B is biased with elastic force against the wall portion 2B while the electrical component 1A is held by the holding portion 2A.

[0030] According to this electrical component support structure, the electrical component unit 1 is held within the cylindrical shape of the wall portion 2B by the elastic force of the flat wiring material 1B and the gripping portion 1C. As a result, the electrical component support structure of this embodiment can stably hold the electrical component unit 1.

[0031] Furthermore, the electrical component support structure of this embodiment has guide portions (recessed portion 1Ab and convex portion 2C) that engage with each other between the mounting portion 2 and the electrical component unit 1 and guide the electrical component 1A to the holding position of the holding portion 2A.

[0032] According to this electrical component support structure, the electrical component unit 1 is guided by the guide portion (recess 1Ab and protrusion 2C) to the holding position of the holding portion 2A. As a result, the electrical component support structure of this embodiment can position the electrical component 1A to the holding position of the holding portion 2A. [Explanation of Symbols]
