[First embodiment]
FIG. 1 is a perspective view schematically showing a mobile terminal device 100 according to the first embodiment, and is a diagram before the flexible member 30 is connected to the conductive member 20. FIG. 2 is a perspective view schematically showing the mobile terminal device 100 according to the first embodiment, and is a view after the flexible member 30 is connected to the conductive member 20. FIG. 3 is a side view of FIG. 2. As shown in FIGS. 1, 2, and 3, a mobile terminal device 100 according to the first embodiment includes a circuit member 10, a conductive member 20, and a flexible member 30. When the flexible member 30 included in the mobile terminal device 100 shown in FIG. 1 is connected to the conductive member 20, the result is as shown in FIGS. 2 and 3, and the flexible member 30 and the conductive member 20 are electrically connected. Note that a display (not shown) is provided in the -Z direction shown in FIGS. 1, 2, and 3.

The mobile terminal device 100 is applicable to devices that perform wireless communication, such as smartphones, pads, and notebook computers. Moreover, the mobile terminal device 100 is applicable to devices using power feeding electrodes and grounding electrodes of general electronic devices such as the above-mentioned mobile terminals. The configuration of the mobile terminal device 100 will be explained below.

The circuit member 10 is a printed circuit board on which electronic components are mounted. A printed circuit board is composed of multiple circuits, insulating resin, and the like.

Examples of the conductive member 20 include a conductive member such as an antenna that receives radio waves. The conductive member 20 has a connecting portion 22 extending toward the circuit member 10 side. The connecting portion 22 extends from the base 21 of the conductive member 20 toward the circuit member 10 side. Further, the conductive member 20 is arranged at a position that does not overlap the circuit member 10 in the vertical direction when viewed from the side in FIG. 3 . That is, the conductive member 20 and the connecting portion 22 that constitutes a part of the conductive member 20 are arranged at positions that do not overlap the circuit member 10 in the vertical direction in plan view and side view.

The flexible member 30 is mounted on the circuit member 10, connects the connecting portion 22 and the circuit member 10, and establishes electrical continuity between the connecting portion 22 and the circuit member 10. The flexible member 30 has two or more points of contact with the connecting portion 22 . The flexible member 30 is made of a metal such as copper, iron, stainless steel, or titanium, and includes a plate spring.

Since the conductive member 20 is arranged in a position that does not overlap the circuit member 10 in the vertical direction when viewed from the side, the distance between the conductive member 20 and the display can be increased, and deterioration of antenna performance can be prevented. can. Further, since the flexible member 30 has two or more points of contact with the connecting portion 22, it is possible to stably ensure conduction between the circuit member 10 and the antenna.

Specific aspects will be explained below.

As shown in FIGS. 1, 2, and 3, the connecting portion 22 of the conductive member 20 is L-shaped and includes a convex portion 23 and a concave portion 24. As shown in FIGS. The convex portion 23 engages with an R portion 35 and a first curved portion 36a, which will be described later.

The flexible member 30 has a fitting part 31 that connects and fits with the convex part 23. The mating portion 31 has an R portion 35 and a first curved portion 36a. In other words, the flexible member 30 is engaged with the conductive member 20 by the R portion 35 and the first curved portion 36a, thereby establishing electrical continuity between the circuit member 10 and the conductive member 20.

As shown in FIG. 3, the R portion 35 has an R shape when viewed from the side. The R portion 35 is in contact with the convex portion 23 at a surface that protrudes in the direction of the convex portion 23 . Further, the first curved portion 36a has a shape that curves in the direction opposite to the R portion 35 toward the convex portion 23, and is in contact with the convex portion 23 at a surface that protrudes in the direction of the convex portion 23. The first curved portion 36a has a J shape, an L shape, or a U shape. In this way, it contacts the connecting portion 22 at two or more points: the R portion 35 and the first curved portion 36a. Further, as shown in FIGS. 1, 2, and 3, the flexible member 30 has a base surface 32 perpendicular to the surface of the circuit member 10, an upper surface 33 extending from the top of the base surface 32 to the R portion 35, and a base surface 33 extending from the top of the base surface 32 to the R portion 35. It has a lower surface 34 extending from the lower part of the surface 32 to the first curved part 36a.

The structure of the connecting portion 22 and flexible member 30 as described above provides the following effects. Even if the position of the circuit member 10 and the positions of the flexible member 30 and the conductive member 20 mounted on the circuit member 10 shift during assembly, and variations occur in these positions, the base surface 32 of the flexible member 30 Since the upper part is tilted in the +X direction or -X direction and the R section 35 is movable in the +X direction or -X direction, and the first curved section 36a is curved, it can follow the above-mentioned positional deviation, and the connection section 22 and Stable conduction can be ensured by adjusting the contact pressure appropriately. Further, stable conduction between the circuit member 10 and the flexible member 30 can be ensured without increasing the number of parts of the device. In addition, since there is no need to tighten screws, workability does not deteriorate and manufacturing can be carried out efficiently. Therefore, it is possible to prevent deterioration of antenna performance and ensure more stable conduction between the circuit member 10 and the antenna. Further, if the depth of the connecting portion 22 of the conductive member 20 is longer than the length (in the Y direction) of the connecting portion 22 of the flexible member 30, the distance between the conductive member 20 and the circuit member 10 is Connection position can be changed freely. Therefore, the length of the antenna can be substantially adjusted.

If the conductive member is placed in a position that overlaps the circuit member in the vertical direction when viewed from the side, power is supplied from the -Z direction surface (back surface) of the circuit member and the power supply part extending from the conductive member. If this is done, changing the power feeding position involves changing the mold, etc., which increases cost and manufacturing time, and cannot be done easily. Furthermore, if the area of the power feeding section is increased and the power feeding position is changed, the antenna characteristics may deteriorate. Furthermore, when the conductive member is placed in a position overlapping the circuit member in the vertical direction when viewed from the side, and power is supplied from the +Z direction surface (surface) of the circuit member and the power supply part extending from the conductive member. Changing the power feeding position involves changing the external shape of the circuit member, which increases cost and manufacturing time, and cannot be easily done. Therefore, since the mobile terminal device 100 according to the first embodiment has the above configuration, the above effects can be obtained.

A preferred form of the flexible member 30 will be described below.

FIG. 4 is a side view showing a modification of the flexible member 30 shown in FIG. As shown in FIG. 4, the first curved portion 36a of the flexible member 30 preferably has a contact portion 40 that further extends and curves from the lower surface 34 and contacts the upper surface 33 of the flexible member 30. .

Even if the positions of the circuit member 10, the flexible member 30 mounted on the circuit member 10, and the conductive member 20 are significantly shifted, deterioration of the antenna performance can be prevented and the conduction between the circuit member 10 and the antenna can be stabilized. and can be secured. For example, when the circuit member 10 shifts in the +X direction (rightward direction), the contact pressure between the R portion 35 of the flexible member 30 and the connecting portion 22 is greater than the contact pressure between the first curved portion 36a and the connecting portion 22. becomes larger, and conduction from the conductive member 20 is to the R portion 35, the upper surface 33 of the flexible member 30, the base surface 32 of the flexible member 30, the lower surface 34 of the flexible member 30, and the circuit member 10. . On the other hand, when the circuit member 10 is displaced in the −X direction (leftward direction), the contact pressure between the first curved portion 36a of the flexible member 30 and the connecting portion 22 is reduced by the contact pressure between the R portion 35 and the connecting portion 22. The conductive member 20 is electrically connected to the first curved portion 36a, the lower surface 34 of the flexible member 30, and the circuit member 10. That is, if the positions of the circuit member 10 or the conductive member 20 are significantly shifted, variations in path length may occur, which may deteriorate the antenna characteristics.

Therefore, by providing the flexible member 30 as shown in FIG. 4 with the abutting portion 40, even if the position of the circuit member 10 or the conductive member 20 is greatly shifted, multiple paths can be prevented from occurring and the path length can be increased. It is possible to suppress variations in antenna performance, prevent deterioration of antenna performance, and ensure stable conduction between the circuit member 10 and the antenna. Note that the first curved portion 36a may further include a contact portion 41 that extends and curves further from the lower surface 34 and contacts the base surface 32 of the flexible member 30.

Further, as shown in FIGS. 1 and 4, a gap 60 may be provided between the R portion 35 and the first curved portion 36a, which is smaller than the thickness of the connecting portion 22 (in the X direction). The gap portion 60 is a gap between the tip of the R portion 35 in the -Z direction and the first curved portion 36a on the lower surface 34 side. In this way, the flexible member 30 can be easily inserted into the convex portion 23 of the connecting portion 22, and the manufacturing of the mobile terminal device 100 can be facilitated.

FIG. 5 is a perspective view showing another modification of the flexible member 30 shown in FIG. As shown in FIG. 5, it is preferable that the flexible member 30 further includes a side surface 37 connecting the upper surface 33 and the lower surface 34. By having the side surface portion 37, the upper surface 33 and the lower surface 34 are prevented from opening, and variations in contact pressure between the connecting portion 22 and the R portion 35 and between the connecting portion 22 and the first curved portion 36a are suppressed, and the circuit member The conduction between the antenna 10 and the antenna can be ensured more stably. Note that the same materials and members as the flexible member 30 are used for the side surface portion 37 as well.

FIG. 6 is a perspective view showing another modification of the flexible member 30 shown in FIG. As shown in FIG. 6, the flexible member 30 preferably has a reinforcing portion 38 that covers the base surface 32 side of the flexible member 30. The reinforcing portion 38 covers the top surface 33 and base surface 32 of the flexible member 30. By having the reinforcing portion 38, the shape of the flexible member 30 is reinforced, and when the flexible member 30 is mounted on the circuit member 10, the weight of the flexible member 30 is balanced, and the weight of the flexible member 30 is balanced during mounting. Misalignment of the flexible member 30 can be suppressed. Note that the reinforcing portion 38 is made of resin or the like.

A preferred form of the conductive member 20 will be described below. FIG. 7 is a perspective view showing a modification of the conductive member 20 shown in FIG. As shown in FIG. 7, the convex portion 23 preferably has a tapered portion 23a.

The second curved portion 36b can also be further curved into a C shape.

In this way, even if the positions of the circuit member 10, the flexible member 30 mounted on the circuit member 10, and the conductive member 20 are further shifted, the first curved portion 36a and the first curved portion 36a of the flexible member 30 Since the two curved portions 36b can be moved and deformed in the +X direction or the −X direction, they can follow the above-mentioned positional deviation, and the contact pressure with the connecting portion 22 can be made appropriate to ensure more stable conduction. In addition, since the second curved portion 36b contacts the first contact portion 25 and the second contact portion 26 at two locations in the +/-Z direction, it is not directly affected by variations in the +X/-X directions, and variations occur. Changes in path length during time are unlikely to occur. Therefore, it is possible to further prevent deterioration of antenna performance and ensure stable conduction between the circuit member 10 and the antenna.
