[0009] (Embodiment) [Structure of antenna component 10] The structure of an antenna component 10 according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the antenna component 10. FIG. 2 is a perspective view of the antenna component 10 with the cover 12 removed. FIG. 3 is a perspective view of the antenna component 10 with the covers 12, 14, and the spacer 18 removed. FIG. 4 is a perspective view of the bobbin 20a, the first terminal 30, and the second terminal 32. FIG. 5 is a perspective view of the bobbin 20a. FIG. 6 is a cross-sectional view of the bobbin 20a, the first terminal 30, and the second terminal 32 perpendicular to the up-down direction. FIG. 7 is an enlarged view of the front part of the first terminal 30 in FIG. 6.

[0010] In the following, the direction in which the main body 20 of the antenna component 10 extends is defined as the front-rear direction. The direction in which the first terminal 30 and the second terminal 32 are arranged is defined as the left-right direction. The direction perpendicular to the front-rear direction and the left-right direction is defined as the up-down direction. Note that the front-rear direction, the left-right direction, and the up-down direction are perpendicular to each other. Also, the front-rear direction, the left-right direction, and the up-down direction are directions defined for convenience, and do not necessarily have to match the front-rear direction, the left-right direction, and the up-down direction when the antenna component 10 is actually used.

[0011] The antenna component 10 is an antenna component for transmitting signals in a short-range communication system in the LF band (30 kHz to 300 kHz). The antenna component 10 is mainly used in a keyless entry system that remotely controls the locking and unlocking of vehicle doors.

[0012] As shown in FIGS. 1 to 3, the antenna component 10 includes covers 12 and 14, a spacer 18, a body 20, a coil antenna 22, connection terminals 24 and 26, a capacitor 28, a first terminal 30, and a second terminal 32.

[0013] The main body 20 has a shape that extends in the forward direction (first direction DIR1). As shown in Fig. 3, the main body 20 includes a bobbin 20a and a core 20b. The core 20b is a plate-like member that has a rectangular shape with long sides extending in the forward and backward directions when viewed in the up-down direction. The material of the core 20b is, for example, Mn-Zn ferrite or other amorphous magnetic material.

[0014] As shown in Fig. 3, the bobbin 20a holds the core 20b, the coil antenna 22, the connection terminals 24, 26, the capacitor 28, the first terminal 30, and the second terminal 32. As shown in Fig. 4, the bobbin 20a includes a terminal support part 200 and a core support part 202. The terminal support part 200 occupies the rear end part of the bobbin 20a. The terminal support part 200 holds the first terminal 30 and the second terminal 32. The terminal support part 200 will be described in detail later.

[0015] As shown in Fig. 3, the core support part 202 is a part of the bobbin 20a excluding the terminal support part 200. The core support part 202 holds the core 20b, the coil antenna 22, the connection terminals 24, 26, and the capacitor 28. Specifically, the core support part 202 has a frame shape surrounding the periphery of the core 20b when viewed in the up-down direction. The material of the bobbin 20a as described above is a resin such as PBT (polybutylene terephthalate).

[0016] As shown in FIG. 3, the connection terminals 24, 26 are attached to the upper surface of the core support portion 202. The connection terminals 24, 26 are made of a conductive material such as copper. The connection terminals 24 and 26 are arranged from front to rear in this order. The connection terminal 24 has a first end t1 and a second end t2. The connection terminal 26 has a first end t11 and a second end t12. The capacitor 28 is connected to the second end t2 of the connection terminal 24 and the first end t11 of the connection terminal 26. That is, the capacitor 28 is connected in series to the connection terminals 24 and 26.

[0017] As shown in Fig. 3, the coil antenna 22 is a conductor wound around the main body 20 with an axis extending in the forward direction (first direction DIR1) as a central axis. More specifically, the coil antenna 22 has a structure in which a conductor having a core wire made of a conductive material such as copper and a surface of which is coated with an insulating material is wound around the core support part 202 (see Fig. 4) of the main body 20. As a result, the coil antenna 22 goes around the core 20b when viewed in the forward / backward direction. The coil antenna 22 includes a first coil portion 22a, a second coil portion 22b, and a third coil portion 22c.

[0018] The first coil portion 22a overlaps with the front portion of the core 20b when viewed in the up-down direction. The first coil portion 22a is wound around the core support portion 202 and the core 20b. The first coil portion 22a has a first coil portion first end portion 22at1 and a first coil portion second end portion 22at2 (the first coil portion first end portion 22at1 is not shown).

[0019] The second coil portion 22b overlaps with the central portion of the core 20b when viewed in the up-down direction. Therefore, the second coil portion 22b is located behind the first coil portion 22a. The second coil portion 22b is wound around the core support portion 202 and the core 20b. The second coil portion 22b has a second coil portion first end 22bt1 and a second coil portion second end 22bt2 (the second coil portion first end 22bt1 is not shown). The first coil portion 22a and the second coil portion 22b are located in front of the connection terminals 24, 26 and the capacitor 28.

[0020] The third coil portion 22c overlaps with the rear portion of the core 20b when viewed in the up-down direction. The third coil portion 22c is wound around the core support portion 202 and the core 20b. The third coil portion 22c has a third coil portion first end portion 22ct1 and a third coil portion second end portion 22ct2. The third coil portion 22c is located behind the connection terminals 24, 26 and the capacitor 28.

[0021] The first coil portion first end 22at1 (not shown) and the second coil portion first end 22bt1 (not shown) are connected. Therefore, the first coil portion 22a and the second coil portion 22b are one conductor. In this manner, the first coil portion 22a and the second coil portion 22b are connected in series.

[0022] The first coil portion second end 22at2 is connected to a first terminal 30 described later. The second coil portion second end 22bt2 is connected to a first end t1 of the connection terminal 24. The third coil portion first end 22ct1 is connected to a second end t12 of the connection terminal 26. The third coil portion second end 22ct2 is connected to a second terminal 32 described later.

[0023] As described above, the first coil portion 22a, the second coil portion 22b, and the third coil portion 22c are connected in series in this order between the first terminal 30 and the second terminal 32. That is, the coil antenna 22 is connected to the first terminal 30 and the second terminal 32. Here, the coil antenna 22 has a first end T1 and a second end T2. The first end T1 coincides with the first coil portion second end 22at2. The second end T2 coincides with the third coil portion second end 22ct2.

[0024] The first terminal 30 is held by the main body 20. In this embodiment, the first terminal 30 is held by a terminal support portion 200 of the bobbin 20a, as shown in FIG. 4. The first terminal 30 is electrically connected to the first end T1 of the coil antenna 22, as shown in FIG. 3. The first terminal 30 is a single metal member. The material of the first terminal 30 is a conductive material such as copper. The mounting structure of the first terminal 30 will be described in detail below.

[0025] 5, the main body 20 includes fixing surfaces S1, S2, the pillars 204a, 206a, the first overlapping portions 204b, 206b, the second overlapping portions 204c, 206c, and the stoppers 204d, 206d. The fixing surfaces S1, S2, the pillars 204a, 206a, the first overlapping portions 204b, 206b, the second overlapping portions 204c, 206c, and the stoppers 204d, 206d are provided on the upper surface of the terminal support portion 200.

[0026] The fixing surface S1 is a flat surface facing upward. The fixing surface S1 has a normal line extending upward (a second direction DIR2 perpendicular to the first direction DIR1). The fixing surface S1 is located on the left side of the terminal support part 200. The fixing surface S1 is located on the rear end part of the terminal support part 200.

[0027] The pillar 204a extends upward (second direction DIR2). The pillar 204a protrudes upward (second direction DIR2) from the fixed surface S1. The pillar 204a is located at the left part of the terminal support part 200. As shown in FIG. 6, the pillar 204a includes a pillar body 205a, a first protrusion 205b, and a second protrusion 205c. The pillar body 205a extends upward (second direction DIR2). The pillar body 205a protrudes upward (second direction DIR2) from the fixed surface S1. The pillar body 205a is a quadrangular pillar. When viewed in the up-down direction, the pillar body 205a has a rectangular shape having two sides extending in the front-rear direction and two sides extending in the left-right direction. The first protrusion 205b protrudes leftward (fourth direction DIR4) from the pillar body 205a. The first protrusion 205b has a convex curved shape when viewed in the up-down direction (second direction DIR2). The convex curved surface protrudes to the left.

[0028] The second protrusion 205c protrudes from the support body 205a in the right direction (third direction DIR3). The second protrusion 205c has a flat surface. The flat surface has a normal line extending in the right direction (second direction DIR2).

[0029] 5, the first overlapping portion 204b is located above the fixing surface S1 (in the second direction DIR2). The first overlapping portion 204b is connected to the support pillar 204a. More specifically, the first overlapping portion 204b extends leftward from the upper end of the support pillar main body 205a. As a result, a space Sp1 is formed below the first overlapping portion 204b and to the left of the support pillar 204a.

[0030] 5, the second overlapping portion 204c is located above the fixing plane S1 (in the second direction DIR2). The second overlapping portion 204c is located behind the fixing plane S1. In addition, a space Sp2 is formed below the second overlapping portion 204c.

[0031] 5 and 6, the stopper 204d is located behind the space Sp2. The stopper 204d protrudes upward from the upper surface of the terminal support portion 200.

[0032] The fixing surface S2, the support 206a, the first overlapping portion 206b, the second overlapping portion 206c, and the stopper 206d have a structure symmetrical to that of the fixing surface S1, the support 204a, the first overlapping portion 204b, the second overlapping portion 204c, and the stopper 204d. Therefore, the description of the fixing surface S2, the support 206a, the first overlapping portion 206b, the second overlapping portion 206c, and the stopper 206d will be omitted.

[0033] As shown in FIG. 6, the first terminal 30 includes a first fixed portion 30a, a second fixed portion 30b, a first connecting portion 30c, a contact portion 30d, a third fixed portion 30e, a protruding portion 30f, and a connecting portion 30g. The first fixed portion 30a extends in the front-rear direction. The first fixed portion 30a is located to the left of the support 204a. As a result, the first terminal 30 is located in the space Sp1 as shown in FIG. 5 and FIG. 6. As shown in FIG. 5 and FIG. 6, the first overlapping portion 204b overlaps with the first fixed portion 30a when viewed in the up-down direction (second direction DIR2). The first overlapping portion 204b is located above the first fixed portion 30a.

[0034] The second fixed portion 30b extends in the front-rear direction as shown in Fig. 6. The second fixed portion 30b is located to the right of the support pillar 204a.

[0035] The first connecting portion 30c is located behind the support 204a (in the fifth direction DIR5 perpendicular to the second direction DIR2). It is connected to the first protrusion 205b and the second protrusion 205c. In this embodiment, the first connecting portion 30c is connected to the rear end of the first fixing portion 30a and the rear end of the second fixing portion 30b. As a result, the first fixing portion 30a, the second fixing portion 30b, and the first connecting portion 30c have a U-shape when viewed in the vertical direction.

[0036] Moreover, the distance between the first fixing portion 30a and the second fixing portion 30b when the first terminal 30 is not attached to the main body 20 is smaller than the distance between the left end of the first protrusion 205b and the right end of the second protrusion 205c. As a result, when the first terminal 30 is attached to the main body 20, the first fixing portion 30a, the second fixing portion 30b, and the first connecting portion 30c are elastically deformed. As a result, the first fixing portion 30a applies a force to the support 204a in the right direction (the third direction DIR3 perpendicular to the second direction DIR2). More precisely, the first fixing portion 30a applies a force to the first protrusion 205b in the right direction (the third direction DIR3). Moreover, the second fixing portion 30b applies a force to the support 204a in the left direction (the fourth direction DIR4 opposite to the third direction DIR3). More precisely, the second fixing portion 30b applies a force to the second protrusion 205c in the left direction (the third direction DIR3).

[0037] As shown in Fig. 6, the contact portion 30d is connected to at least one of the first fixing portion 30a, the second fixing portion 30b, and the first connecting portion 30c. In this embodiment, the contact portion 30d is connected to the rear end of the second fixing portion 30b. The contact portion 30d extends in the rear direction (a fifth direction DIR5 perpendicular to the second direction DIR2). When the antenna component 10 is attached to a connector (not shown), the contact portion 30d comes into contact with an input / output terminal of the connector.

[0038] As shown in FIG. 6, the third fixed portion 30e is connected to the second fixed portion 30b. In this embodiment, the third fixed portion 30e is connected to the front end of the second fixed portion 30b. The third fixed portion 30e extends from the second fixed portion 30b in the front direction (first direction DIR1). The front end of the third fixed portion 30e is located in the space Sp2 as shown in FIG. 5 and FIG. 6. Therefore, when viewed in the up-down direction (second direction DIR2), the second overlapping portion 204c overlaps with the front end (end in the first direction DIR1) of the third fixed portion 30e. The second overlapping portion 204c is located above the third fixed portion 30e.

[0039] 7, the protrusion 208a of the terminal support portion 200 is in contact with the left surface of the third fixed portion 30e, and the protrusion 208b of the terminal support portion 200 is in contact with the right surface of the third fixed portion 30e.

[0040] As shown in FIG. 7, the protrusion 30f protrudes from the third fixed portion 30e in the right or left direction (third direction DIR3 or fourth direction DIR4). In this embodiment, the protrusion 30f protrudes from the third fixed portion 30e in the right direction. Here, the stopper 204d is located behind the protrusion 30f (fifth direction DIR5). The stopper 204d is in contact with the protrusion 30f. However, there may be a slight gap between the stopper 204d and the protrusion 30f.

[0041] 6 and 7, the connection portion 30g extends in a left front direction from the third fixed portion 30e. As shown in FIG. 3, the first end T1 of the coil antenna 22 is connected to the connection portion 30g.

[0042] The second terminal 32 is held by the main body 20. The second terminal 32 is electrically connected to the second end T2 of the coil antenna 22. However, the second terminal 32 has a structure that is symmetrical to the structure of the first terminal 30. Therefore, a description of the second terminal 32 will be omitted.

[0043] 2, the spacer 18 is located in front of the first coil portion 22a and the second coil portion 22b, above the first coil portion 22a and the second coil portion 22b, and below the first coil portion 22a and the second coil portion 22b. Therefore, the spacer 18 has a U-shape when viewed in the left-right direction. The material of the spacer 18 is, for example, resin.

[0044] The cover 14 is located at the rear end of the main body 20. The cover 14 has a cylindrical shape with a central axis extending in the front-rear direction. The cover 14 covers the first terminal 30 and the second terminal 32. However, the rear end of the cover 14 is open.

[0045] 1, the cover 12 covers the spacer 18, the main body 20, the coil antenna 22, the connection terminals 24, 26, and the capacitor 28. The front end of the cover 12 is not open. The rear end of the cover 12 is open. The material of the covers 12, 14 is, for example, resin.

[0046] [effect] According to the antenna component 10, the first terminal 30 can be firmly fixed to the main body 20. More specifically, the first fixing portion 30a applies a force to the support 204a in the right direction. The second fixing portion 30b applies a force to the support 204a in the left direction. That is, the first terminal 30 sandwiches the support 204a from the left and right directions by elastically deforming the first terminal 30. Therefore, even if the support 204a is slightly scraped by the first terminal 30 when the first terminal 30 is attached to the main body 20, no gap is formed between the first terminal 30 and the support 204a. As a result, according to the antenna component 10, the first terminal 30 can be firmly fixed to the main body 20.

[0047] According to the antenna component 10, the first terminal 30 sandwiches the support post 204a from the left and right directions by elastically deforming the first terminal 30. Therefore, the first terminal 30 is prevented from rotating about an axis extending in the front-rear direction.

[0048] According to the antenna component 10, the first terminal 30 sandwiches the support post 204a from the left and right directions by elastically deforming the first terminal 30. Therefore, the first terminal 30 does not need to be welded to the bobbin 20a. However, the first terminal 30 may be welded to the bobbin 20a.

[0049] According to the antenna component 10, the first terminal 30 can be easily attached to the main body 20. More specifically, the first fixing portion 30a applies a force to the first protrusion 205b in the right direction. The second fixing portion 30b applies a force to the second protrusion 205c in the left direction. That is, the first fixing portion 30a and the second fixing portion 30b each apply a force to the protrusion. As a result, by sliding the first terminal 30 forward relative to the main body 20, it is possible to attach the first terminal 30 to the main body 20 while widening the gap between the first fixing portion 30a and the second fixing portion 30b by the first protrusion 205b and the second protrusion 205c. As described above, according to the antenna component 10, the first terminal 30 can be easily attached to the main body 20.

[0050] According to the antenna component 10, the first terminal 30 can be easily positioned relative to the main body 20. More specifically, the first protrusion 205b has a convex curved shape when viewed in the up-down direction. The second protrusion 205c has a plane having a normal line extending in the right direction. This allows the second fixing portion 30b to contact the plane of the second protrusion 205c. Thus, the second fixing portion 30b is positioned relative to the second protrusion 205c. As a result, according to the antenna component 10, the first terminal 30 can be easily positioned relative to the main body 20.

[0051] The antenna component 10 prevents the first terminal 30 from coming off the main body 20. More specifically, when viewed in the up-down direction, the first overlapping portion 204b overlaps with the first fixed portion 30a. This prevents the first fixed portion 30a from being displaced in the up-down direction relative to the main body 20 by the first overlapping portion 204b. As a result, the antenna component 10 prevents the first terminal 30 from coming off the main body 20.

[0052] The antenna component 10 prevents the first terminal 30 from coming off the main body 20. More specifically, when viewed in the up-down direction, the second overlapping portion 204c overlaps with the front end of the third fixing portion 30e. This prevents the third fixing portion 30e from being displaced in the up-down direction relative to the main body 20 by the second overlapping portion 204c. As a result, the antenna component 10 prevents the first terminal 30 from coming off the main body 20.

[0053] The antenna component 10 prevents the first terminal 30 from coming off the main body 20. More specifically, the stopper 204d is located rearward of the protruding portion 30f and is in contact with the protruding portion 30f. This prevents the first terminal 30 from being displaced rearward relative to the main body 20 by the stopper 204d. As a result, the antenna component 10 prevents the first terminal 30 from coming off the main body 20.

[0054] (First Modification) The antenna component 10a according to the first modified example will be described below with reference to the drawings. Fig. 8 is a perspective view of the vicinity of the support post 204a of the antenna component 10a.

[0055] The antenna component 10a differs from the antenna component 10 in that the first terminal 30 further includes a second connecting portion 30h. More specifically, the second connecting portion 30h is located in front of the support 204a (in the first direction DIR1). The second connecting portion 30h is connected to the first fixing portion 30a and the second fixing portion 30b. As a result, when viewed in the vertical direction, the first fixing portion 30a, the second fixing portion 30b, the first connecting portion 30c, and the second connecting portion 30h have a ring shape surrounding the support 204a. The other structures of the antenna component 10a are the same as those of the antenna component 10, so that the description thereof will be omitted. The antenna component 10a can achieve the same effects as those of the antenna component 10.

[0056] (Second Modification) The antenna component 10b according to the second modified example will be described below with reference to the drawings. Fig. 9 is a perspective view of the vicinity of the support post 204a of the antenna component 10b.

[0057] The antenna component 10b differs from the antenna component 10 in that the first terminal 30 further includes a fourth fixing portion 30i, a fifth fixing portion 30j, and a third connecting portion 30k. More specifically, the fourth fixing portion 30i extends in the front-rear direction. The fourth fixing portion 30i is located below the first overlapping portion 204b. The fourth fixing portion 30i is connected to the first fixing portion 30a.

[0058] The fifth fixed portion 30j extends in the front-rear direction. The fifth fixed portion 30j is located above the first overlapping portion 204b. The third connecting portion 30k is located behind the first overlapping portion 204b. The third connecting portion 30k is connected to the fourth fixed portion 30i and the fifth fixed portion 30j.

[0059] The fourth fixing portion 30i applies a force in an upward direction to the first overlapping portion 204b. The fifth fixing portion 30j applies a force in a downward direction to the first overlapping portion 204b. The other structures of the antenna component 10b are the same as those of the antenna component 10, and therefore a description thereof will be omitted. The antenna component 10b can achieve the same effects as the antenna component 10.

[0060] According to the antenna component 10b, the fourth fixing portion 30i and the fifth fixing portion 30j sandwich the first overlapping portion 204b from above and below. This suppresses the first terminal 30 from being displaced in the vertical direction relative to the main body 20.

[0061] (Other embodiments) The antenna components according to the present invention are not limited to the antenna components 10, 10a, and 10b, and may be modified within the scope of the present invention. Furthermore, the structures of the antenna components 10, 10a, and 10b may be combined in any desired manner.

[0062] Although the first direction DIR1 is described as the forward direction, it may be a direction other than the forward direction.

[0063] Although the second direction DIR2 is described as the upward direction, it may be a direction other than the upward direction. The second direction DIR2 only needs to be perpendicular to the first direction DIR1.

[0064] Although the third direction DIR3 is described as the rightward direction in the above embodiment, it may be a direction other than the rightward direction. The third direction DIR3 only needs to be perpendicular to the second direction DIR2.

[0065] Although the fourth direction DIR4 is described as the leftward direction in the above embodiment, it may be a direction other than the leftward direction. The fourth direction DIR4 may be any direction opposite to the third direction DIR3.

[0066] Although the fifth direction DIR5 is described as the rear direction in the above embodiment, it may be a direction other than the rear direction. The fifth direction DIR5 may be any direction as long as it is perpendicular to the second direction DIR2.

[0067] It should be noted that the first protrusion 205b and the second protrusion 205c are not essential components.

[0068] The first protrusion 205b may have a flat surface when viewed in the vertical direction, and the second protrusion 205c may have a convex curved surface when viewed in the vertical direction.

[0069] It should be noted that the first overlapping portion 204b and the second overlapping portion 204c are not essential components.

[0070] It should be noted that the stopper 204d is not an essential component.

[0071] The contact portion 30d may be connected to at least one of the first fixed portion 30a, the second fixed portion 30b, and the first connecting portion 30c.

[0072] It should be noted that the first terminal 30 only needs to be electrically connected to the first end T1 of the coil antenna 22. Therefore, the first terminal 30 does not need to be directly connected to the first end T1 of the coil antenna 22.

[0073] It is sufficient that the second terminal 32 is electrically connected to the second end T2 of the coil antenna 22. Therefore, the second terminal 32 does not have to be directly connected to the second end T2 of the coil antenna 22.

[0074] The protruding portion 30f may protrude to the left.

[0075] The antenna component 10b does not necessarily have to include the first fixing portion 30a, the second fixing portion 30b, and the first connecting portion 30c. In this case, the first overlapping portion 204b functions as a support. [Explanation of symbols]
