[Figure 9] This is a plan view of the glass with a security sensor according to the embodiment.

[0009] Embodiments of the present invention will be described below with reference to Figures 1 to 9. In all drawings, similar components are denoted by the same reference numerals, and their descriptions are omitted where appropriate. Note that in Figure 6, the connector 110 is not shown.

[0010] As shown in any of Figures 1 to 9, the security sensor-equipped glass 100 according to this embodiment includes a window glass 86 (see Figure 9) on which a conductive pattern 87 (see Figure 9) is formed, a connector housing 82 attached to the window glass 86 and electrically connecting the conductive pattern 87 and the system 200, an inductor 83 for noise suppression (see Figures 1 and 2), a base 20 that supports the connector housing 82 and fixes the inductor 83, and an inductor case 60 attached to the base 20 in a manner that covers the inductor 83. The connector housing 82 includes a case portion 70 having a hollow portion 76 into which the connector 110 (see Figures 1 and 2) is inserted. The case portion 70 has the first connector pin 44 and the second connector pin 42, which are made of conductive material, inserted into it by insert molding. The base 20 has a first terminal pin 56 and a second terminal pin 51, both made of conductive material, inserted into it (Figure 7, etc.). The first terminal pin 56 has a first terminal portion 59 electrically connected to the conductive pattern 87 and a first support portion 58 rising from the first terminal portion 59 at one end of the first terminal pin 56, and also has a first coil connection terminal portion 57. The second terminal pin 51 has a second terminal portion 54 electrically connected to the conductive pattern 87 and a second support portion 53 rising from the second terminal portion 54 at one end of the second terminal pin 51, and also has a second coil connection terminal portion 52. The first terminal portion 59, the first support portion 58, the first coil connection terminal portion 57, the second terminal portion 54, the second support portion 53, and the second coil connection terminal portion 52 are each exposed from the base 20. The inductor 83 comprises an E-core 10 which is a magnetic material, and a first air-core coil 15b and a second air-core coil 15a which are externally fitted to the legs (outer legs 12 in this embodiment) at both ends of the E-core 10, respectively (Figure 4, etc.). One end of the first air-core coil 15b is electrically connected to the first connector pin 44, and the other end of the first air-core coil 15b is electrically connected to the first coil connection terminal portion 57. One end of the second air-core coil 15a is electrically connected to the second connector pin 42, and the other end of the second air-core coil 15a is electrically connected to the second coil connection terminal portion 52.

[0011] According to this embodiment, the inductor 83 includes the E-core 10, the first air-core coil 15b, and the second air-core coil 15a. Therefore, compared with the case of using a chip inductor and a circuit board, the productivity of the security sensor 81 can be improved. That is, a glass 100 with a security sensor having a structure capable of further improving productivity can be realized.

[0012] In the following description, the vertical direction is referred to as the Z direction. Down (downward) is the side where the first terminal portion 59 and the second terminal portion 54 are arranged, that is, the mounting surface side of the security sensor 81 (window glass 86 side). However, the positional relationship of each part during the manufacture or use of the glass 100 with a security sensor (especially the vertical positional relationship) does not necessarily coincide with the positional relationship described in this specification. The axial direction of each of the first air-core coil 15b and the second air-core coil 15a extends in a direction orthogonal to the Z direction. The axial direction of each of the first air-core coil 15b and the second air-core coil 15a is referred to as the Y direction. One in the Y direction is referred to as front (forward), and the other is referred to as back (rear). Also, a direction orthogonal to both the Y direction and the Z direction is referred to as the X direction. One in the X direction is referred to as left (leftward), and the other is referred to as right (rightward). These directions are shown in each figure. Also, a direction orthogonal to the Z direction is referred to as horizontal (horizontal direction), and a direction along the Z direction is referred to as vertical (vertical direction). Furthermore, unless otherwise specified, the positional relationships of the various parts of the security sensor-equipped glass 100 describe the positional relationships of the parts of the security sensor-equipped glass 100 when they are assembled together to produce the security sensor-equipped glass 100.

[0013] In this embodiment, as an example, the security sensor 81 is attached to the reinforced glass of a four-wheeled vehicle, and detects when the reinforced glass of the vehicle is shattered, thereby detecting that the conductive pattern 87 has been broken. More specifically, as schematically shown in Figure 9, the window glass 86 has, for example, two conductive patterns 87 formed on it. Each of the first terminal pins 56 and the second terminal pin 51 is mounted to the corresponding conductive pattern 87. Each of the first terminal pins 56 and the second terminal pin 51 and the conductive pattern 87 are electrically and mechanically connected to each other, for example, by solder (or welding). The window glass 86 is not particularly limited, but for example, it is a vehicle window glass. Also, if the window glass 86 is a vehicle window glass, the system 200 will henceforth be referred to as the vehicle system 200. The security sensor 81 is not particularly limited, but for example, it is a sensor for detecting wire breakage, and the conductive pattern 87 is not particularly limited, but for example, it is a pattern for detecting wire breakage in the window glass 86. The vehicle system 200 is not particularly limited, but for example, it is a wire breakage detection system. However, in the present invention, the security sensor 81, the conductive pattern 87, and the vehicle system 200 are not limited to these examples, and may, for example, detect phenomena caused by actions such as picking, such as vibration. Furthermore, the inductor 83 (first air-core coil 15b and second air-core coil 15a) acts as a noise filter. The noise that the inductor 83 removes (attenuates) may include, for example, radio waves in the FM band (76MHz~108MHz) and DAB (Digital Audio Broadcast) Band III (174MHz~240MHz) band received by a vehicle antenna (not shown), but it is not limited to radio waves in these broadcast frequency bands. In addition, noise can also include radio waves in frequency bands that are irregularly generated from vehicles, so the specifications of the inductor 83 should be designed appropriately according to the radio waves in the frequency bands that should be attenuated. The vehicle system 200 and the connector 110 are configured to be electrically connected to each other. As shown in Figure 1, when the connector 110 is inserted into the connector housing 82, the vehicle system 200 and the conductive pattern 87 are electrically connected to each other via the security sensor 81.

[0014] The E-core 10 is, for example, a so-called E-core, and its planar shape is formed in an E-shape (see Figure 4). The E-core 10 comprises a base portion 13 extending in the left-right direction, a pair of left and right outer legs 12 projecting forward from both ends of the base portion 13, and a middle leg portion 14 projecting forward from the middle of the base portion 13. In this embodiment, the pair of left and right outer legs 12 are the legs at both ends of the E-core. Therefore, the corresponding first air-core coil 15b and second air-core coil 15a are extrapolated to each of the left and right outer legs 12. Furthermore, the direction in which the outer leg portion 12 and the middle leg portion 14 protrude from the base portion 13 is the same as the axial direction of the first air-core coil 15b and the second air-core coil 15a. The base portion 13 is, for example, elongated from left to right, and its cross-sectional shape perpendicular to the axial direction is formed as a rectangular prism. However, the cross-sectional shape of the base portion 13 is not particularly limited and may be cylindrical, for example. In the base portion 13, two of the four surfaces arranged around the axis are horizontal upper and lower surfaces, respectively, while one of the remaining two surfaces (hereinafter referred to as the inner surface) faces inward and the other (hereinafter referred to as the outer surface) faces outward. In this embodiment, the inner surface of the base portion 13 constitutes the inner surface of the E core 10, and the outer surface of the base portion 13 constitutes the outer surface of the E core 10. Each outer leg portion 12 and middle leg portion 14 is, for example, elongated in the front-to-back direction and formed as a rectangular prism with a cross-sectional shape perpendicular to the axial direction. However, the cross-sectional shape of each of the outer leg portion 12 and middle leg portion 14 is not particularly limited and may be, for example, cylindrical. In each of the outer leg portion 12 and the middle leg portion 14, two of the four surfaces arranged around the axis are horizontal upper and lower surfaces, respectively, while one of the remaining two surfaces faces to the right and the other faces to the left. The base 13, each outer leg 12, and the middle leg 14 are set to have the same vertical dimensions, for example. In the E-core 10, the upper surface of the base 13, the upper surface of the outer leg 12, and the upper surface of the middle leg 14 are flush with each other. That is, the overall upper surface of the E-core 10 is formed flat and is horizontally positioned. Similarly, in the E-core 10, the lower surface of the base 13, the lower surface of the outer leg 12, and the lower surface of the middle leg 14 are flush with each other. That is, the overall lower surface of the E-core 10 is formed flat and is horizontally positioned.

[0015] Thus, for example, each of the legs at both ends of the E-core 10 (outer legs 12 in this embodiment) and the central leg of the E-core 10 (middle leg 14 in this embodiment) are formed in a rectangular prism shape with a cross-sectional shape perpendicular to their respective axial directions. Furthermore, the E-core 10 is arranged such that, for example, each of the legs at both ends (outer legs 12) and the central leg of the E-core 10 (middle leg 14) extends horizontally and is aligned horizontally with respect to each other, and each of the legs at both ends and the central leg are formed to have the same vertical dimensions.

[0016] In this embodiment, as shown in Figure 2, each of the first terminal pin 56 and the second terminal pin 51 has a flat plate portion (in this embodiment, the first flat plate portion 56a and the second flat plate portion 51a) embedded in the base 20. As shown in Figures 5, 6, and 7, one or both of the first support portion 58 and the second support portion 53 have a rising portion (in this embodiment, the rising portion 53b of the second support portion 53) that rises upward from the flat plate portion, and a folded portion (in this embodiment, the folded portion 53a of the second support portion 53) that is folded downward from the upper end of the rising portion toward the first terminal portion 59 or the second terminal portion 54. With this configuration, the presence of the rising portion 53b and the folded portion 53a allows the second support portion 53 to be easily elastically deformed, thereby mitigating the thermal stress caused by the heat of soldering (or welding) when mounting the security sensor 81 to the window glass 86. In other words, the stress acting on the window glass 86 and the second air-core coil 15a can be reduced. Furthermore, even when the glass 100 with the security sensor is subjected to vibration or when the ambient temperature around the security sensor 81 becomes high, the second support portion 53 can be easily elastically deformed, thereby reducing the stress acting on the window glass 86 and the second air-core coil 15a.

[0017] More specifically, as shown in Figure 2, each of the first terminal pin 56 and the second terminal pin 51 is, for example, a plate-shaped metal member such as a copper plate. The first terminal pin 56 has, for example, a first flat plate portion 56a, a first coil connection terminal portion 57, a first support portion 58, and a first terminal portion 59. Furthermore, the second terminal pin 51 includes, for example, a second flat plate portion 51a, a second coil connection terminal portion 52, a second support portion 53, and a second terminal portion 54. Furthermore, of the first support portion 58 and the second support portion 53, the second support portion 53 has a rising portion 53b and a folded portion 53a. However, in the present invention, of the first support portion 58 and the second support portion 53, the first support portion 58 may have a rising portion and a folded portion, or both the first support portion 58 and the second support portion 53 may each have a rising portion and a folded portion.

[0018] As shown in Figures 2, 7, and 8, the first flat plate portion 56a is formed in a shape that is elongated in the front-to-back direction, for example. The first support portion 58 hangs down from the front edge of the first flat plate portion 56a toward the first terminal portion 59, for example. The first coil connection terminal portion 57 rises upward from the rear end of the first flat plate portion 56a, for example. Furthermore, the first coil connection terminal portion 57 is formed, for example, in a substantially L-shape in plan view, and includes a portion extending in the front-to-back direction and a portion extending in the left-to-right direction. The front end of the first coil connection terminal portion 57 is connected to the first flat plate portion 56a, and the right end of the first coil connection terminal portion 57 stands upright.

[0019] More specifically, the first flat plate portion 56a is, for example, arranged horizontally. The first terminal pin 56 has a bent plate surface at the boundary between the first support portion 58 and the first terminal portion 59 (for example, bent by 90 degrees), and also at the boundary between the first support portion 58 and the first flat plate portion 56a (for example, bent by 90 degrees). Furthermore, the plate surface is also bent at the boundary between the first flat plate portion 56a and the first coil connection terminal portion 57 (for example, bent by 90 degrees). As a result, the first support portion 58 is perpendicular to both the first flat plate portion 56a and the first terminal portion 59. Also, the first flat plate portion 56a is positioned above the first terminal portion 59.

[0020] The second flat plate portion 51a is formed, for example, in a substantially L-shape in plan view, and includes a portion extending in the front-to-back direction and a portion extending in the left-to-right direction. The rising portion 53b rises upward from the rear end of the second flat plate portion 51a, and the folded portion 53a is folded downward from the upper end of the rising portion 53b toward the second terminal portion 54. The second coil connection terminal portion 52 rises upward from, for example, the left end of the second flat plate portion 51a. Furthermore, the second coil connection terminal portion 52 is also formed in a substantially L-shape in plan view, for example, and includes a portion extending front to back and a portion extending left to right. The front end of the second coil connection terminal portion 52 is connected to the second flat plate portion 51a, and the left end of the second coil connection terminal portion 52 stands upright.

[0021] More specifically, the second flat plate portion 51a is, for example, arranged horizontally. The first terminal pin 56 has its plate surface bent at the boundary between the second support portion 53 and the second terminal portion 54 (for example, bent by 90 degrees), and also at the boundary between the second support portion 53 and the second flat plate portion 51a (for example, bent by 90 degrees). Furthermore, the plate surface is bent at the boundary between the rising portion 53b and the folded portion 53a (for example, bent by 180 degrees). As a result, the second support portion 53 (rising portion 53b and folded portion 53a) is perpendicular to the second flat plate portion 51a and the second terminal portion 54, respectively. As shown in Figure 7, the upper edge of the rising portion 53b and the upper edge of the folded portion 53a are positioned at approximately the same height, while the lower edge of the rising portion 53b is positioned above the lower edge of the folded portion 53a. Therefore, the second flat plate portion 51a is positioned above the second terminal portion 54. Furthermore, the plate surface is also bent at the boundary between the second flat plate portion 51a and the second coil connection terminal portion 52 (for example, bent at a 90-degree angle).

[0022] Thus, in this embodiment, the first flat plate portion 56a, the first coil connection terminal portion 57, the first support portion 58, and the first terminal portion 59 are each made up of a portion of the first terminal pin 56 which is bent. Similarly, the second flat plate portion 51a, the second coil connection terminal portion 52, the second support portion 53 (folded portion 53a and rising portion 53b), and the second terminal portion 54 are each made up of a portion of the second terminal pin 51 which is bent.

[0023] Furthermore, as shown in Figures 7 and 8, the height of the lower edge of the first support portion 58 of the first terminal pin 56 is set to be approximately the same as the height of the lower edge of the second support portion 53 of the second terminal pin 51 (the height of the lower edge of the folded portion 53a). Therefore, the first terminal portion 59 and the second terminal portion 54 are positioned at approximately the same height. Furthermore, the height of the upper edge of the first support portion 58 of the first terminal pin 56 is set to be approximately the same as the height of the lower edge of the second support portion 53 of the second terminal pin 51 (the height of the lower edge of the rising portion 53b). Therefore, the first flat plate portion 56a of the first terminal pin 56 and the second flat plate portion 51a of the second terminal pin 51 are positioned at the same height relative to each other.

[0024] The first terminal pin 56 is formed, for example, with a uniform thickness throughout. Similarly, the second terminal pin 51 is formed, for example, with a uniform thickness throughout. Furthermore, the first terminal pin 56 and the second terminal pin 51 are formed, for example, with equivalent thicknesses to each other.

[0025] As shown in Figures 2, 3, and 4, the base 20 has, for example, a first retaining portion 36 and a second retaining portion 31 that are arranged side by side in the horizontal direction. More specifically, in this embodiment, the base 20 includes a first retaining portion 36 located on the front side, a second retaining portion 31 located on the rear side, and a connecting portion 35 that connects the first retaining portion 36 and the second retaining portion 31 to each other. In Figure 6, the base 20 is shown by a dashed line. The first holding portion 36 is formed in a substantially flat shape, for example, being elongated in the front-to-back direction and having a vertical dimension smaller than the horizontal dimension. The second holding portion 31 is formed, for example, in a substantially rectangular parallelepiped shape. The left-right width dimension of the front portion of the second holding portion 31 is set to be smaller than the left-right width dimension of the rear portion of the second holding portion 31. A recessed housing 32 is formed on the upper surface of the second holding portion 31, which is recessed downwards. The housing recess 32 is open, for example, upwards and on the opposite side from the first holding portion 36 (rear in this embodiment). The E core 10, the first air-core coil 15b, and the second air-core coil 15a are housed inside the housing recess 32. In addition, a plurality of positioning protrusions are formed on the bottom surface of the housing recess 32, which are raised upwards, and these positioning protrusions make it easy to position the E core 10 relative to the housing recess 32. The connecting portion 35 is formed in a substantially flat shape, for example, being elongated from left to right and having a front-to-back dimension smaller than its top-to-bottom dimension. A portion of the upper end of the connecting portion 35 is chamfered.

[0026] As shown in Figure 4, the left-right width dimension of the first holding portion 36 is set to be larger than, for example, the left-right width dimension of the connecting portion 35 and the left-right width dimension of the second holding portion 31. The maximum left-right width dimension of the second holding portion 31 is set to be larger than the left-right width dimension of the connecting portion 35. Furthermore, the front-to-back dimensions of the first holding portion 36 are set to be larger than, for example, the front-to-back dimensions of the connecting portion 35 and the front-to-back dimensions of the second holding portion 31. The front-to-back dimensions of the second holding portion 31 are set to be larger than, for example, the front-to-back dimensions of the connecting portion 35.

[0027] As described above, the first terminal pin 56 and the second terminal pin 51 are each insert-molded into the base 20. This improves the structural strength of the security sensor 81. More specifically, as shown in Figure 6, etc., the portion of the first terminal pin 56 excluding the front end of the first flat plate portion 56a is embedded across the first holding portion 36, the connecting portion 35, and the second holding portion 31. Also, the portion of the first coil connection terminal portion 57 excluding the upper end is embedded in the second holding portion 31. On the other hand, the front end of the first flat plate portion 56a, the first support portion 58, and the first terminal portion 59 are exposed to the outside, for example, from the front surface of the first holding portion 36. Furthermore, the upper end of the first coil connection terminal portion 57 is exposed to the outside from the right side surface of the second holding portion 31. As shown in Figure 7, etc., the portion of the second terminal pin 51 excluding the rear end of the second flat plate portion 51a is embedded in the second holding portion 31. Also, the portion of the second coil connection terminal portion 52 excluding the upper end is embedded in the second holding portion 31. On the other hand, the rear end of the second flat plate portion 51a, the second support portion 53, and the second terminal portion 54 are exposed to the outside, for example, from the rear surface of the second holding portion 31. Also, the upper end of the second coil connection terminal portion 52 is exposed to the outside from the left side surface of the second holding portion 31.

[0028] Furthermore, as shown in Figures 6, 7, and 8, the first terminal pin 56 and the second terminal pin 51 are embedded in the base 20 at a distance from each other. As a result, the first terminal pin 56 and the second terminal pin 51 are electrically isolated from each other.

[0029] As shown in Figures 1, 2, and 7, the inductor case 60 is formed in a hollow, roughly rectangular parallelepiped shape that is open to the front and the bottom, respectively. More specifically, the inductor case 60 includes, for example, a top surface portion 61 that covers the upper part of the second holding portion 31. More specifically, the inductor case 60 has a rear surface portion 62 extending downward from the rear edge of the top surface portion 61, and a pair of left and right side surfaces 63 extending downward from the side peripheral edges of the top surface portion 61. The top surface 61 is formed, for example, as a flat plate and is arranged horizontally. Each of the pair of left and right side surfaces 63 is formed as a flat plate and is arranged vertically.

[0030] In this embodiment, the inductor case 60 is mounted on the second retaining portion 31, for example, so as to cover the upper end of the second retaining portion 31. More specifically, as shown in Figures 7 and 8, the top surface portion 61 covers the upper part of the second retaining portion 31, the left side portion 63 covers the left side of the second retaining portion 31, and the right side portion 63 covers the right side of the second retaining portion 31.

[0031] The inner surface of the left side portion 63 is in surface contact with the left side surface of the second retaining portion 31. The inner surface of the right side portion 63 is in surface contact with the right side surface of the second retaining portion 31. As a result, the inductor case 60 is mounted (fitted) onto the second retaining portion 31 while sandwiching it from both sides. However, the inductor case 60 and the second holding part 31 may be fixed to each other by, for example, an adhesive or adhesive tape (not shown). Furthermore, the rear surface 62 of the inductor case 60 has, for example, a notched portion that penetrates the rear surface 62 from front to back. As shown in Figure 7, the second support portion 53 and the second terminal portion 54 of the second terminal pin 51 are exposed to the outside of the inductor case 60 through the notched portion.

[0032] As shown in Figures 1, 2, and 7, the case portion 70 has, for example, an opening 70b that is open to the front and is formed in a roughly rectangular parallelepiped shape that is elongated in the front-to-back direction. When the connector 110 is inserted into the connector housing 82, the connector 110 is inserted into the hollow portion 76 of the case portion 70 through the opening 70b. More specifically, the case portion 70 includes, for example, a top portion 71, a rear surface portion 72 extending downward from the rear edge of the top portion 71, a pair of left and right side portions 73 extending downward from the side peripheral edges of the top portion 71, and a bottom surface portion 74 that closes the lower end of the case portion 70. Each of the ceiling portion 71 and the rear portion 72 is formed, for example, as a flat plate and is arranged horizontally. Each of the pair of left and right side portions 73 is formed as a flat plate and is arranged vertically.

[0033] In this embodiment, a through hole 70a is formed in the ceiling portion 71 of the case portion 70, reaching the hollow portion 76. Furthermore, a protrusion 71a is formed inside the hollow portion 76, hanging down from the edge of the through hole 70a and engaging with the connector 110. Since the through-hole 70a is formed in the ceiling portion 71, it is easy to visually confirm whether the protrusion 71a is engaged with the connector 110. More specifically, the through-hole 70a penetrates the ceiling portion 71 vertically. The through-hole 70a is formed, for example, in the front part of the ceiling portion 71. In plan view, the through-hole 70a is formed in a substantially rectangular shape. In this embodiment, a pair of front and rear protrusions 71a are formed within the hollow portion 76. More specifically, each of the front and rear protrusions 71a is arranged front to back with a through hole 70a in between. As shown in Figure 7, each of the front and rear protrusions 71a protrudes downward from the lower surface of the ceiling portion 71 and extends in the front-to-back direction. The thickness of the portion of the front protrusion 71a excluding its rear end gradually decreases toward the front, for example. Furthermore, the rear end surface of the front protrusion 71a is inclined to gradually displace toward the rear toward the downward direction, for example. Similarly, the front end surface of the through hole 70a is inclined to gradually displace toward the rear toward the downward direction, for example.

[0034] Here, the connector housing 82 has a plurality of protrusions 75 that project downward from the lower surface of the connector housing 82. Multiple recesses 37 are formed on the upper surface of the base 20, each into which a projection 75 is inserted. Furthermore, the first terminal pin 56 has an opening 56b that penetrates the first flat plate portion 56a vertically. As shown in Figures 6 and 7, at least one projection 75 penetrates the opening 56b. With this configuration, when assembling the base 20 and the connector housing 82 together, the projection 75 can be inserted into the corresponding recess 37 to easily position the connector housing 82 relative to the base 20. Furthermore, since at least one projection 75 penetrates the opening 56b, interference between the first terminal pin 56 and the projection 75 is suppressed, and the base 20 and the connector housing 82 can be assembled to each other in a desired positional relationship.

[0035] More specifically, in this embodiment, the multiple (for example, four) protrusions 75 project downward from the lower surface of the bottom surface 74 of the case portion 70. Each protrusion 75 is set to have the same shape and dimensions as the others, for example. Multiple (for example, four) recesses 37 are formed, for example, on the upper surface of the first retaining portion 36. Each recess 37 is set to have the same shape and dimensions as the others. Each recess 37 is formed in a shape and position corresponding to the projection 75, and a corresponding projection 75 is inserted into each recess 37. More specifically, each projection 75 is formed in a cylindrical shape, for example, with its axial direction being vertical. The outer diameter of each projection 75 gradually decreases towards the bottom. Each recess 37 is also formed in a cylindrical shape, for example, with the vertical direction as its axial direction, and the inner diameter of each recess 37 gradually decreases towards the bottom.

[0036] Furthermore, as shown in Figure 7, as an example, two of the four protrusions 75 penetrate the opening hole 56b. More specifically, the two projections 75 that penetrate the opening 56b are, for example, arranged side by side in the front-to-back direction on the lower surface of the bottom surface 74, with the front projection 75 located in the middle of the lower surface (in the front-to-back direction) and the rear projection 75 located in the rear of the lower surface. The remaining two protrusions 75 are arranged side by side in the left-right direction on the front part of the lower surface of the bottom surface 74, and the front end of the first flat plate portion 56a is positioned between these protrusions 75. Similarly, on the upper surface of the first retaining portion 36, for example, two recesses 37 are arranged side by side in the front-to-back direction, with the front recess 37 located in the middle of the upper surface (in the front-to-back direction) and the rear recess 37 located in the rear part of the upper surface. The remaining two recesses 37 are arranged side by side in the left-right direction, for example, on the front part of the upper surface of the first retaining portion 36. As an example, the opening 56b is formed in the center of the first flat plate portion 56a in the first terminal pin 56. In plan view, the opening 56b is formed in an elongated oval shape. In the first holding portion 36, two recesses 37, arranged side by side, pass through the opening 56b.

[0037] Thus, in this embodiment, two or more of the multiple protrusions 75 are arranged side by side in the first direction in the horizontal direction. Also, in this embodiment, two or more of the multiple protrusions 75 are arranged side by side in the horizontal direction that is perpendicular to the first direction.

[0038] When assembling the base 20 and the case portion 70, each projection 75 is inserted into the corresponding recess 37. In this state, the upper surface of the first retaining portion 36 and the lower surface of the bottom portion 74 are in surface contact with each other. Furthermore, the outer circumferential surface of each projection 75 and the inner circumferential surface of the corresponding recess 37 are joined to each other via adhesive. However, in this invention, the upper surface of the first retaining portion 36 and the lower surface of the bottom portion 74 may also be joined to each other via adhesive. Furthermore, in this embodiment, the boundary between the rear portion 72 and the bottom portion 74 has a shape that corresponds to the chamfered shape of a part of the upper end of the connecting portion 35 (i.e., a chamfered shape), and the boundary portion and the part of the upper end of the connecting portion 35 are engaged with each other. Furthermore, the left-right width dimension of the case portion 70 is set to be approximately the same as the left-right width dimension of the first holding portion 36. The front-to-back dimension of the case portion 70 is set to be slightly smaller than the sum of the front-to-back dimensions of the first holding portion 36 and the front-to-back dimensions of the connecting portion 35. As a result, the entire lower surface of the bottom portion 74 is in surface contact with the upper surface of the base 20 (a portion of the upper surface of the first holding portion 36 and the upper end surface of the connecting portion 35).

[0039] As described above, the first connector pin 44 and the second connector pin 42, which are made of conductive material, are insert-molded into the case portion 70. This ensures sufficient structural strength between the first connector pin 44 and the second connector pin 42. In this embodiment, the first connector pin 44 and the second connector pin 42 are formed in a symmetrical shape relative to each other. More specifically, the first connector pin 44 is formed, for example, in a substantially L-shape in plan view and includes a first portion 45 extending front to back and a second portion 46 projecting to the right from the rear end of the first portion 45. The tip of the second portion 46 is upright. Similarly, the second connector pin 42 is formed, for example, in a substantially L-shape in plan view, and includes a first portion 45 and a second portion 46 projecting to the left from the rear end of the first portion 45. The tip of the second portion 46 is upright.

[0040] As shown in Figure 8, in this embodiment, each first portion 45 is insert-molded so as to penetrate the rear surface portion 62 of the case portion 70 from front to back. More specifically, the front end of each first section 45 is positioned in front of the front surface of the rear section 62 and is located within the hollow section 76 of the case section 70. The ends of each first section 45 are then inserted into the connector 110, which will be described later. This electrically connects the connector 110 with the first connector pin 44 and the second connector pin 42. Furthermore, the intermediate portion of each first section 45 is embedded in the rear surface portion 72 of the case portion 70. On the other hand, as shown in Figure 4, the rear end of each first portion 45 and the second portion 46 protrude rearward from the rear surface of the rear surface portion 62 and are located outside the hollow portion 76 of the case portion 70. The other end of the corresponding coil (first air-core coil 15b and second air-core coil 15a) is fixed to the upper end of each second portion 46. Furthermore, in this embodiment, the first connector pin 44 and the second connector pin 42 are embedded in the case portion 70 at a distance from each other. As a result, the first connector pin 44 and the second connector pin 42 are electrically isolated from each other.

[0041] As described above, the inductor 83 includes a first air-core coil 15b and a second air-core coil 15a. As shown in Figure 2, the first air-core coil 15b and the second air-core coil 15a are each composed of windings. Each of the first air-core coil 15b and the second air-core coil 15a includes a winding portion 16 formed by winding the windings. As shown in Figures 3 and 4, one end of each of the first air-core coil 15b and the second air-core coil 15a is electrically connected to the corresponding connector pins 42 and 44, respectively. For example, one end of the first air-core coil 15b is pulled out from the winding section 16 and wrapped around the upper end of the second portion 46 of the first connector pin 44, and fixed by solder 91 (or welding, crimping, etc.). Similarly, one end of the second air-core coil 15a is pulled out from the winding section 16 and wrapped around the upper end of the second portion 46 of the second connector pin 42, and fixed by solder 91 (or welding, crimping, etc.). Furthermore, the other end of each of the first air-core coil 15b and the second air-core coil 15a is electrically connected to the corresponding coil connection terminals 52 and 57, respectively. More specifically, the other end of the first air-core coil 15b is pulled out from the winding section 16 and wrapped around the upper end of the first coil connection terminal 57, and fixed by solder 91 (or welding, crimping, etc.). Similarly, the other end of the second air-core coil 15a is pulled out from the winding section 16 and wrapped around the upper end of the second coil connection terminal 52, and fixed by solder 91 (or welding, crimping, etc.).

[0042] As shown in Figure 4, in this embodiment, the first air-core coil 15b is externally mounted on the right outer leg portion 12, and the second air-core coil 15a is externally mounted on the left outer leg portion 12. This configuration places the middle leg portion 14 between the first air-core coil 15b and the second air-core coil 15a, thereby appropriately weakening the degree of magnetic coupling generated around each of the first and second air-core coils. In other words, the desired characteristics of the inductor 83 can be achieved.

[0043] As shown in Figures 1, 2, and 7, the connector 110 includes a main body portion 115 and a spring piece 120 provided at the upper end of the main body portion 115, which elastically biases the case portion 70. The main body 115 is formed, for example, in a roughly rectangular parallelepiped shape that is elongated in one direction. Then, with the longitudinal direction of the main body 115 and the longitudinal direction of the hollow portion 76 of the case 70 aligned, the connector 110 is inserted into the connector housing 82. Furthermore, the main body 115 has a pair of left and right insertion holes 131 into which the corresponding first connector pin 44 and second connector pin 42 are inserted, respectively. Each of the left and right insertion holes penetrates the main body 115 from front to back. The spring piece 120 extends, for example, in the front-to-back direction, and has a cantilever structure in which the rear end of the spring piece 120 is supported. The intermediate portion of the spring piece 120 in the longitudinal direction contacts the protrusion 71a of the case portion 70 and biases the protrusion 71a. More specifically, the upper surface of the spring piece 120 has a pair of grooves 125 (in this embodiment, a pair of front and rear grooves 125) that are recessed downwards, and one protrusion 71a of the case portion 70 engages with each groove 125. The spring piece 120 is inclined such that at the point of contact between the bottom surface of the groove 125 and the protrusion 71a, the connector 110 generates a force that biases the case portion 70 upwards. In this embodiment, the front portion of the spring piece 120 is inclined upwards toward the front. Furthermore, in this embodiment, on the upper surface of the spring piece 120, an upwardly convex upper projection 126 is formed between a pair of grooves 125. As shown in Figure 7, when the connector 110 is inserted into the case portion 70, the upper projection 126 is inside the through hole 70a. With this configuration, it is possible to restrict the displacement of the connector 110 relative to the case portion 70 in the front-to-back direction.

[0044] When the connector 110 is inserted into the case portion 70, the spring piece 120 is pushed down by the lower surface of the ceiling portion 71 of the case portion 70, and elastically deforms from an upward sloping state toward forward to a downward sloping state toward forward. Then, when the connector 110 is inserted into the case portion 70 until the upper projection 126 reaches the through hole 70a, the spring piece 120 elastically returns to its original state, and the protrusions 71a corresponding to each groove portion 125 engage. In this embodiment, the rear end surface of the upper projection 126, which is positioned between the front and rear grooves 125, is an inclined surface that is gradually displaced towards the rear in a downward direction. Therefore, when inserting the connector 110 into the case 70, the spring piece 120 is smoothly guided towards the rear by the rear convex portion 71a along the inclined surface of the upper projection 126. Furthermore, in this embodiment, the front end surface of the upper projection 126 is a vertical surface, while the rear end surface of the front convex portion 71a, as described above, is an inclined surface that is gradually displaced towards the rear in a downward direction. Therefore, the front end surface of the projection and the rear end surface of the front convex portion 71a can more reliably restrict the relative displacement of the connector 110 with respect to the case portion 70 in the front-rear direction. Furthermore, the foremost end of the spring piece 120 is provided with a pressing portion 122 that receives a pressing operation on the spring piece 120. To remove the connector 110 from the case portion 70, the engagement of the protrusion 71a with the groove portion 125 is released by pressing the pressing portion 122 downward against the elastic force of the spring piece 120. While maintaining this state, the connector 110 can be removed from the case portion 70 by pulling it out.

[0045] As shown in Figure 3, when the connector 110 is inserted into the case portion 70, the front end of the first portion 45 of the first connector pin 44 is inserted into the right insertion hole 131, and the front end of the first portion 45 of the second connector pin 42 is inserted into the left insertion hole 131. In addition, the rear end surface of the main body portion 115 is in close proximity to or in surface contact with, for example, the front surface of the rear surface portion 72 of the case portion 70. Furthermore, the pressing portion 122 of the spring piece 120 and the front end of the main body portion 115 are exposed to the outside of the case portion 70 through the opening 70b of the case portion 70.

[0046] The E-core 10 is integrally molded from magnetic material. The base 20 (the second holding portion 31 and the first holding portion 36) is, for example, integrally molded from an insulating material such as resin. The inductor case 60 is, for example, integrally molded from an insulating material such as resin. The case portion 70 is, for example, integrally molded from an insulating material such as resin. The connector 110 is, for example, integrally molded from an insulating material such as resin.

[0047] The security sensor 81 can be assembled, for example, as follows:

[0048] First, a base 20 is prepared with the first terminal pin 56 and the second terminal pin 51 insert-molded into it. Similarly, a case portion 70 is prepared with the first connector pin 44 and the second connector pin 42 each insert-molded into it. Then, the first air-core coil 15b is inserted into the left outer leg portion 12 of the E-core 10, and the second air-core coil 15a is inserted into the right outer leg portion 12 of the E-core 10. Next, the base 20 and the case portion 70 are assembled together. More specifically, adhesive is applied to the inside of each recess 37 of the base 20. Then, each projection 75 of the case portion 70 is inserted into the corresponding recess 37. Next, the E-core 10, with the first air-core coil 15b and the second air-core coil 15a each externally fitted, is placed in the housing recess 32 of the second holding portion 31. Then, for example, the front end surface of the E-core 10 is fixed to the inner surface of the housing recess 32 with an adhesive or the like. Next, one end of the first air-core coil 15b is electrically and mechanically connected to the first connector pin 44, and the other end of the first air-core coil 15b is electrically and mechanically connected to the first coil connection terminal portion 57. Similarly, one end of the second air-core coil 15a is electrically and mechanically connected to the second connector pin 42, and the other end of the second air-core coil 15a is electrically and mechanically connected to the second coil connection terminal portion 52. In this way, the security sensor 81 is obtained.
