[0001] The present invention relates to a switching device. [Technical background]

[0002] In the switching device described in patent document 1 below, an antenna coil is wound around one end of a cylindrical body, and a coil connector is inserted into the body. One end of the coil connector protrudes from the body, while the end of the antenna coil is wound around the end of the coil connector. The other end of the coil connector, however, protrudes from the body inside a connector housing and is configured as a connector terminal. This enables communication via the antenna coil. [State of the art document][Patent document]

[0003] [Patent Document 1] JP 2015-187968 A [Summary of the invention][Problem to be solved by the invention]

[0004] However, as already mentioned, the aforementioned switching device requires that the coil connection be configured as a single piece by casting it into the body, which can increase the manufacturing costs of the switching device. Therefore, there is potential for improvement in the aforementioned switching device to reduce manufacturing costs.

[0005] In view of the aforementioned facts, the present invention aims to provide a switching device whose manufacturing costs can be reduced. [Means of solving the problem]

[Advantages of the invention]

[0007] According to the switching device in the aforementioned configuration, manufacturing costs can be reduced.

[Embodiments of the invention]

[0008] The following is an explanation of the switching device 10 according to the present embodiment with reference to the drawings. The switching device 10 according to the present embodiment is arranged in the dashboard or the like of the vehicle (motor vehicle) and is configured as a device for starting or stopping the engine (drive unit) in the vehicle. As shown in the Fig. 1 (A) and Fig. As shown in Figure 1 (B), the switching device 10 is generally cylindrical in shape. In the following explanation, the axially oriented side (the side in the direction of arrow A) is shown. Fig. 1 (A)) of the switching device 10 the front of the switching device 10 and the other side lying in the axial direction (the side in the direction of arrow B in Fig. 1 (A)) of the switching device 10, the rear side of the switching device 10. In the front view, viewed from the front, the direction orthogonal to the front-back direction is the first direction (see arrows C and D in Fig. 1 (B)) and the direction orthogonal to the first direction, the second direction (see arrows E and F in Fig. 1 (B)). Furthermore, the side in the direction of arrow C is in Fig. 1 (B) the side in the first direction and the side in the direction of arrow E in Fig. 1 (B) the side in the second direction.

[0009] As in the Fig. As shown in Figures 1 to 3, the switching device 10 is configured to comprise a housing 20, a body 30, a switching mechanism 40, and an antenna wire 60. An explanation of the individual components of the switching device 10 follows. (Regarding case 20)

[0010] The housing 20 is formed in a double, approximately cylindrical shape, with the front-to-back direction being an axial direction. In other words, the housing 20 has an outer cylinder 20A and an inner cylinder 20B, the inner cylinder 20B being arranged radially inside the outer cylinder 20A. The two ends in the second direction, at the front end of the outer cylinder 20A and inner cylinder 20B, are also coupled to each other. A pair of mounting pieces 20C are formed in sections on both sides of the outer circumference of the outer cylinder 20A in the first direction. Viewed from the second direction, the mounting pieces 20C are inclined radially outwards towards the front of the housing 20. The mounting pieces 20C also engage with the dashboard or the like of the vehicle, thereby securing the housing 20 (i.e., the switching device 10) to the vehicle.An inlet recess 20D, reduced radially by one step towards the outside, is formed on the inner circumference of the rear end of the outer cylinder 20A. The inner cylinder 20B is formed in an approximately cylindrical shape, open towards the front, with a base, the rear wall of the inner cylinder 20B being located further forward than the rear end of the outer cylinder 20A. On the rear wall of the inner cylinder 20B, both a hole for exposing part of a rubber contact 50 described below and a hole for inserting the lens 56 are formed as required. An aperture 22 is mounted at the front end of the housing 20. Specifically, a cylindrical inlet cylinder part 20E is provided at the front end of the housing 20, projecting from the front end of the outer cylinder 20A towards the front. The aperture 22 is formed in an approximately cylindrical shape, with the front-to-back direction being an axial direction.The aperture 22 is inserted into the inlet cylinder part 20E from the outside and is mounted on the outer cylinder 20A by means of a snap connection in such a way that relative movement is prevented. (Regarding body 30)

[0011] As in the Fig. As shown in Figures 2 to 7, the body 30 is formed in an approximately cylindrical shape with a base, the front-to-back direction being axial and the shape open towards the front. The body 30 is inserted into the housing 20 from the rear and mounted to the housing 20 by means of a snap-fit ​​connection such that relative movement is prevented. When the body 30 is mounted to the housing 20, the inner cylinder 20B is located inside the body 30. In other words, the front part of the body 30 is positioned between the outer cylinder 20A and the inner cylinder 20B, with the body 30 being radially covered from the outside by the outer cylinder 20A. The rear of the body 30 is positioned flush with the rear end face of the outer cylinder 20A.On the outer circumference of the rear end of the body 30, a stepped part 30A is formed, raised by one step in the radial direction towards the outside, which is fitted into the inlet recess 20D of the housing 20.

[0012] The front end of the body 30 is configured as a coil section 30B. The coil section 30B is concave, opening radially towards the outside of the body 30 and extending circumferentially. The interior of the coil section 30B is an antenna wire receiving section 30B1, in which the antenna wire 60, described below, is wound around the coil section 30B within the antenna wire receiving section 30B1. When the body 30 is mounted to the housing 20, the rear end of the coil section 30B rests against the inner circumferential surface of the outer cylinder 20A, and the body 30 is positioned at a predetermined distance radially from the outside of the inner cylinder 20B. In other words, the construction is designed such that movement of the body 30 in the radial direction is restricted due to the outer cylinder 20A and the inner cylinder 20B.

[0013] An opening 30C is formed in the side wall of the body 30, at the other end in the second direction. The opening 30C is formed in the form of a groove, with the front-to-back direction being the longitudinal direction and the opening extending radially (second direction), and the front end of the opening 30C opening towards the front (see Fig. 5 to 7). In other words, part of the coil section 30B is cut out through the opening 30C, and the interior of the opening 30C and the antenna wire receiving section 30B1 are connected. The opening 30C extends from the coil section 30B to the stage section 30A, with the rear end of the opening 30C configured as an exposure opening section 30C1 for arranging and exposing the antenna connection section 42A of the board 42, described below. The width dimension of the exposure opening section 30C1 is set larger than the width dimension of the opening 30C.

[0014] On the outer circumference of the aforementioned inner cylinder 20B of the housing 20, at the other end in the second direction (position corresponding to the opening 30C) there is a regulating part 20F (see Fig. 2 and Fig. 4) formed. The regulating part 20F is formed in a column-like shape, extending in the front-to-back direction, and extends from the front to the rear end of the inner cylinder 20B. The width dimension of the regulating part 20F is set slightly smaller than the width dimension of the opening 30C, the regulating part 20F being fitted into the opening 30C and engaging with the body 30 in the circumferential direction.

[0015] The rear wall of the body 30 is provided with a plurality of mounting ribs 30D, described below, for mounting the circuit board 42. The mounting ribs 30D project from the rear wall to the front and are located on the rear side of the inner cylinder 20B. A single mounting rib 30D is formed in an approximately rectangular plate shape, the second direction being a plate thickness direction. It is arranged so close to one side in the second direction of the exposure opening section 30C1 that the rear part of the exposure opening section 30C1 is blocked from one side in the second direction (see Figure 1). Fig. 2 and Fig. 5) A connector part 30E is provided in approximately the middle section of the rear wall of the body 30. The connector part 30E is formed in an approximately rectangular cylindrical shape, with the front-to-back direction being an axial direction, and projects from the rear wall of the body 30 to the rear side. (Regarding the shift mechanism 40)

[0016] As in the Fig. 2, Fig. 3 and Fig. As shown in Figure 5, the switching mechanism 40 is housed inside the body 30. The switching mechanism 40 is configured to include a circuit board 42, a rubber contact 50, a slider 52, and a lens 56. (Regarding board 42)

[0017] As in Fig. As shown in Figure 6, the circuit board 42 is formed in an approximately disc shape, with the front-back direction being a plate thickness direction. The circuit board 42 is housed in a section at the rear end of the body 30 and is clamped in the front-back direction by the mounting ribs 30D of the body 30 and the rear wall of the inner cylinder 20B of the housing 20, thereby securing it to the housing 20 and the body 30.

[0018] At each end of the first side, a fixed contact 43 is provided on the front of the circuit board 42. An illumination LED 44 is provided in approximately the middle section of the front of the circuit board 42, while an indicator LED 45 is provided at the end of one side in the second direction on the front of the circuit board 42. The illumination LED 44 and the indicator LED 45 are configured to emit light towards the front.

[0019] On the rear side of the circuit board 42, a plurality of connector terminals 46 (eight in the present embodiment) are provided as connector connections, extending in the front-to-back direction. Four connector terminals 46 are arranged side by side in the first direction, with the terminals arranged side by side in the first direction forming the first pair and two pairs of connector terminals 46 arranged side by side in the second direction. The front ends of the connector terminals 46 are bent outwards in the second direction and connected to the rear side of the circuit board 42. The rear ends of the connector terminals 46 project from the rear wall of the body 30 to the rear side and are located inside the connector part 30E. Through holes are formed in the rear wall of the body 30 through which the connector terminals 46 are inserted.An external connector inserted into connector part 30E is connected to the connector terminals 46, thereby electrically connecting the circuit board 42 to the control unit of the vehicle.

[0020] At the other end of the circuit board 42 in the second direction, a pair of antenna connectors 42A is provided as a single unit. The pair of antenna connectors 42A has a rectangular cross-section in the radial direction, projects radially from the outer circumference of the circuit board 42 to the outside (other side in the second direction), and is oriented in the first direction. The pair of antenna connectors 42A is located approximately in the middle section of the exposure opening section 30C1 of the body 30, with the antenna connectors 42A being exposed radially to the outside due to the exposure opening section 30C1 before the housing 20 is mounted to the body 30 (see Fig. 5 and Fig. 7) After the housing 20 is mounted to the body 30, the antenna connection parts 42A are covered from the outside in a radial direction due to the outer cylinder 20A of the housing 20 (see Fig. 2) The width dimension of the antenna connection parts 42A and the opening 30C is set such that the pair of antenna connection parts 42A is arranged inside the opening 30C when viewed from the front (see Fig. 4) Specifically, the distance between the side surface on one side of the antenna connector 42A in the first direction and the side surface on the other side of the antenna connector 42A in the first direction is set slightly smaller than the width dimension of the opening 30C. The surface of the antenna connectors 42A is plated, and the antenna connectors 42A are connected to the connector terminals 46 via a pattern formed on the circuit board 42. In other words, the antenna connectors 42A and the connector terminals 46 are conductively connected. Furthermore, by plating the radially rectangular surfaces of the antenna connection parts 42A, the radially rectangular corners of the antenna connection parts 42A are removed, resulting in a smoother shape, which reduces the load on the antenna wire 60 when the antenna wire 60 is wound onto the antenna connection parts 42A. (Regarding the rubber contact 50)

[0021] As in the Fig. 2, Fig. 3 and Fig. As shown in Figure 5, the rubber contact 50 has a base part 50A, which is formed in a plate shape, with the front-back direction being a plate thickness direction, and the rubber contact is arranged adjacent to the front of the circuit board 42. A pair of switch parts 50B are formed on the base part 50A at locations corresponding to the fixed contacts 43 of the circuit board 42. The switch parts 50B are formed in an approximately dome shape, rising from the rubber contact 50 towards the front, and movable contacts (not shown) are provided inside the switch parts 50B. This means that pressing the switch parts 50B towards the rear (side with the fixed contacts 43) activates the switch parts 50B. Specifically, the switch parts 50B are configured to switch on when the movable contacts touch the fixed contacts 43.

[0022] On the base part 50A, a lighting cylinder part 50C is formed at a location corresponding to the lighting LED 44. The lighting cylinder part 50C is formed in an approximately rectangular cylindrical shape and projects from the rubber contact 50 towards the front, with the interior of the lighting cylinder part 50C running in the front-to-back direction. On the base part 50A, a display cylinder part 50D is formed at a location corresponding to the display LED 45. The display cylinder part 50D is formed in an approximately rectangular cylindrical shape and projects from the rubber contact 50 towards the front. (Regarding slide 52)

[0023] The slide 52 is formed in an approximately rectangular cylindrical shape, with the front-back direction being an axial direction. The slide 52 is inserted into the inner cylinder 20B of the housing 20 and is slidably coupled to the inner cylinder 20B in the front-back direction. In other words, the slide 52 is slidably housed in the body 30 in the front-back direction. When the slide 52 is housed in the body 30, its front end projects further towards the front than the body 30 and the housing 20.

[0024] A push-button switch 52A is formed on the side wall of the slide 52 at a location corresponding to the switch parts 50B of the rubber contact 50. The push-button switch 52A is formed in an approximately cross-shaped beam extending in the front-to-back direction and is arranged adjacent to the front of the switch parts 50B. In a section on one side of the slide 52 in the second direction, a lens housing 52B is formed, in which the lens 56 described below is housed. The lens housing 52B is formed in an approximately rectangular cylindrical shape, with the front-to-back direction being an axial direction, and the lens housing 52B is arranged in the front view at a location that overlaps with the indicator LED 45.

[0025] A knob 52C is integrally formed at the front end of the slide 52. The knob 52C is approximately disc-shaped, with the front-to-back direction corresponding to the plate thickness, and projects from the outer circumference of the slide 52 such that it covers the body 30 and the inner cylinder 20B from the front. A roughly rectangular lens hole 52D is formed through a section on one side of the knob 52C in the second direction. Furthermore, a lighting hole 52E is formed through approximately the middle section of the knob 52C. The lighting hole 52E is roughly rectangular and, in the front view, is positioned at a location that overlaps with the lighting LED 44.

[0026] A design panel 54, made of a light-transmitting resin material, is provided on the front of the knob part 52C. The design panel 54 is circular in shape, corresponding to the knob part 52C in the front view, and has a concave shape that opens towards the rear. The design panel 54 is attached to the knob part 52C in one piece by two-color injection molding. The design panel 54 is arranged radially within the cover 22 and is accessible from the cabin side of the vehicle. This causes the slider 52 to slide towards the rear when the design panel 54 is operated by the operator, thereby actuating the switch parts 50B of the switch mechanism 40.

[0027] In the design panel 54, a continuous indicator hole 54A is formed at a location corresponding to the lens hole 52D in the knob part 52C. The design panel 54 also features an indicator inscription 54B, consisting of letters, symbols, etc., which is located on the front of the illumination hole 52E of the knob part 52C. The indicator inscription 54B is formed, for example, by blackening the front of the design panel 54 and removing the symbol corresponding to the indicator inscription 54B by laser processing or similar means. This allows the light emitted by the illumination LED 44 to pass through the slider 52 and the illumination hole 52E, thus illuminating the indicator inscription 54B. (Regarding lens 56)

[0028] The lens 56 is made of a transparent resin material that allows light to pass through. The lens 56 is formed in an approximately elongated plate shape, with the second direction being the plate thickness direction and the front-to-back direction being the longitudinal direction. The lens 56 is inserted from the rear into the lens housing part 52B of the slide 52 and mounted to the slide 52 via a snap-fit ​​connection. An indicator part 56A is provided at the front end of the lens 56. The indicator part 56A is inserted from the rear into the lens hole 52D of the knob part 52C and into the indicator hole 54A of the design panel 54, and is exposed from the design panel 54 to the front. The lens 56 is located on the front of the indicator LED 45, with the light emitted by the indicator LED 45 being directed via the lens 56 to the front, thereby illuminating the indicator part 56A. (Regarding antenna wire 60)

[0029] As in the Fig. As shown in Figures 2 to 5 and 7, the antenna wire 60 is wound circumferentially around the coil part 30B of the body 30 and arranged in the antenna wire receiving part 30B1. In other words, the antenna wire 60 is wound around the coil part 30B between the outer cylinder 20A and the inner cylinder 20B of the housing 20. One end 60A and the other end 60B, as the ends of the antenna wire 60, are extended from the antenna wire receiving part 30B1 to the rear and routed within the opening 30C of the body 30. One end 60A of the antenna wire 60 is wound around one antenna connector 42A of the circuit board 42 and soldered to it, while the other end 60B of the antenna wire 60 is wound around the other antenna connector 42A of the circuit board 42 and soldered to it. In other words, one end 60A and the other end 60B of the antenna wire 60 are directly connected to the circuit board 42, and thus the antenna wire 60 is electrically connected to the connector terminals 46. (Effect)

[0030] The following is an explanation of the effect and operation of the switching device 10 according to the present embodiment.

[0031] In the non-operating state of the switching device 10, which is configured as above, the slide 52 is in a home position (in the Fig. 2 and Fig. (3 position shown). When the design panel 54 of the slider 52 is actuated by pressure, the slider 52 slides towards the rear. This causes the switch push-button 52A of the slider 52 to press against the pair of switch parts 50B of the rubber contact 50. Consequently, the movable contacts of the pair of switch parts 50B touch the fixed contacts 43 of the circuit board 42, thereby activating the pair of switch parts 50B and sending an activation signal to the vehicle's control unit. Conversely, when the actuation of the slider 52 is released, the slider 52 slides towards the front due to the restoring force of the switch parts 50B of the rubber contact 50. This causes the knob part 52C to return to its initial position.

[0032] The vehicle's control unit is also connected to the operator's mobile device via communication and starts or stops the vehicle's engine (drive unit) by operating the switching device 10 after successful authentication with the mobile device. The switching device 10 also includes the antenna wire 60. If the operator's mobile device battery is depleted and communication with the mobile device is no longer possible, communication with the mobile device can be established via transponder communication.In detail, when the mobile device is held over the design panel 54 of the switching device 10, the mobile device receives activation radio waves emitted by the wound antenna wire 60 of the switching device 10, which generates an electromotive force in the transponder of the mobile device due to the coil, causing the mobile device to send an ID signal to an authentication device of the vehicle, thereby enabling communication between the authentication device of the vehicle and the mobile device.

[0033] In this case, the switching device 10 comprises a cylindrical body 30. The coil section 30B is provided at the front end of the body 30, with the antenna wire 60 wound around the coil section 30B. The circuit board 42 is arranged inside the body 30, and the connector terminals 46 are provided on the rear side of the circuit board 42. The antenna connection parts 42A, conductively connected to the connector terminals 46, are also provided on the circuit board 42, with one end 60A and the other end 60B of the antenna wire 60 being soldered to the antenna connection parts 42A. In this way, compared to a body in which the connector terminals are molded into the body, as in the prior art, the body 30 can be manufactured at a lower cost, and the antenna wire 60 can be connected to the connector terminals 46.In other words, the body 30 can be manufactured more cost-effectively due to the direct connection of the antenna wire 60 to the circuit board 42 provided with the connector terminals 46. This reduces the manufacturing costs of the switching device 10.

[0034] The radially extending opening 30C is formed in the side wall of the body 30, through which the antenna connection part 42A is exposed radially towards the outside of the body 30. This allows one end 60A and the other end 60B of the antenna wire 60 wound around the coil part 30B to be connected to the antenna connection parts 42A exposed in the opening 30C. This improves the ease of assembly of the switching device 10 and thus further reduces the manufacturing costs of the switching device 10.

[0035] The coil section 30B is also designed in a concave shape, open radially towards the outside of the body 30, with the interior of the coil section 30B being the antenna wire receiving section 30B1. The antenna wire receiving section 30B1 and the opening 30C are connected to each other. This allows one end 60A and the other end 60B of the antenna wire 60 wound around the coil section 30B to be removed from the antenna wire receiving section 30B1 towards the rear, placed in the opening 30C, and connected to the antenna connection parts 42A exposed through the opening 30C (the exposure opening section 30C1). Furthermore, the opening 30C makes it possible to clearly identify the points for removing the antenna wire 60 wound around the coil section 30B at one end (60A) and the other end (60B). This further improves the ease of assembly of the switching device 10.This allows the manufacturing costs of the switching device 10 to be reduced even further.

[0036] The antenna connectors 42A project radially from the outer circumference of the circuit board 42 towards the outer surface of the body 30 and are located in the exposed opening section 30C1 of the opening 30C. This allows the antenna connectors 42A to be soldered to one end 60A and the other end 60B of the antenna wire 60 while they are positioned radially from the inner circumferential surface of the body 30 towards the outer surface. This further improves the processability when soldering the antenna wire 60 to the antenna connectors 42A.

[0037] Furthermore, the width dimension of the exposure opening section 30C1 in the body 30 is wider than the width dimension of the opening 30C, and the antenna connection parts 42A are arranged in the exposure opening section 30C1. This ensures, on the one hand, the rigidity of the body 30 and, on the other hand, a working area for soldering the antenna wire 60 to the antenna connection parts 42A.

[0038] The opening 30C is formed in a groove shape extending in the front-to-back direction, with the front end of the opening 30C opening towards the front at the front end of the body 30. Thus, the mounting of the circuit board 42 and the antenna wire 60 to the body 30 can begin by placing the circuit board 42 on the front of the body 30 (see Fig. 6) and the antenna connectors 42A are inserted into the opening 30C from the front in this state, while the circuit board 42 is housed in the body 30. In other words, the circuit board 42 can be housed in the body 30 while the interference of the antenna connectors 42A with the body 30 is suppressed by the opening 30C. After the circuit board 42 is housed in the body 30, the antenna wire 60 is wound around the coil part 30B, and then one end 60A and the other end 60B of the antenna wire 60 can be connected by soldering to the antenna connectors 42A located in the exposed opening section 30C1 (see Fig. 7) In this way, the machinability of the switching device 10 during assembly can be effectively improved. This effectively reduces the manufacturing costs of the switching device 10.

[0039] Furthermore, as already mentioned, the antenna connectors 42A project radially from the outer circumference of the circuit board 42, and one end 60A and the other end 60B of the antenna wire 60 are soldered to the antenna connectors 42A. In other words, the antenna connectors 42A form part of the circuit board 42, their surfaces are plated, and they are electrically connected to the connector terminals 46 via the pattern. This allows the circuit board 42 to be manufactured more cost-effectively than, for example, a configuration in which the connection terminal for connecting the antenna wire 60 to the circuit board 42 is provided separately.

[0040] Furthermore, the body 30 is attached to the housing 20. The housing 20 consists of the outer cylinder 20A, which covers the body 30 radially from the outside, and the inner cylinder 20B, which is located inside the body 30. The slide 52 is slidably coupled to the inner cylinder 20B in the front-to-back direction. Consequently, there is no need to include a component within the body 30 that slidably couples with the slide 52. Thus, the body 30 and the coil section 30B can have a simple design. In other words, the complexity of the body 30's shape can be avoided. This can further reduce the cost of the body 30.

[0041] Furthermore, the coil section 30B is arranged between the outer cylinder 20A and the inner cylinder 20B of the housing 20. In other words, the antenna wire 60 is positioned between the outer cylinder 20A and the inner cylinder 20B and is radially covered from the outside by the outer cylinder 20A. This can, for example, improve the water and dust resistance of the antenna wire 60. In this way, the reliability of the switching device 10 can be improved. Furthermore, after the body 30 is mounted to the housing 20, the antenna connection parts 42A are radially covered from the outside by the outer cylinder 20A of the housing 20. Thus, the housing 20 ensures the water and dust resistance of the antenna connection parts 42A even if the antenna connection parts 42A are configured, due to the opening 30C, to be exposed by the body 30.

[0042] In the assembled state of the body 30 attached to the housing 20, the rear end of the coil section 30B rests against the inner circumferential surface of the outer cylinder 20A, and the body 30 is positioned at a predetermined distance in the radial direction from the outer surface of the inner cylinder 20B, such that movement of the body 30 in the radial direction is restricted by the outer cylinder 20A and the inner cylinder 20B. Thus, deformations of the relevant side wall in the radial direction can be suppressed by means of the housing 20, even if part of the side wall of the body 30 is cut out by means of the opening 30C.

[0043] The regulating element 20F is formed on the outer circumference of the inner cylinder 20B of the housing 20, and at the other end in the second direction. The regulating element 20F is fitted into the opening 30C and engages with the body 30 in the circumferential direction of the body 30. Thus, deformations of the relevant side wall in the radial direction can be suppressed by means of the regulating element 20F, even if part of the side wall of the body 30 is cut out due to the opening 30C. Furthermore, by forming the regulating element 20F on the outer circumference of the inner cylinder 20B, the regulating element 20F can be fitted into the opening 30C, while the interference of the antenna wire 60 wound around the coil part 30B with the regulating element 20F is suppressed.

[0044] Furthermore, the antenna connection parts 42A are formed as a single unit on the circuit board 42, projecting radially outwards from the outer circumference of the circuit board 42. This eliminates the need for separate components such as terminals as antenna connection parts 42A, which can further reduce manufacturing costs.

[0045] In the present embodiment, soldering is used as the means for attaching one end 60A and the other end 60B of the antenna wire 60 to the antenna connector 42A; however, the method for attaching the antenna wire 60 and the antenna connectors 42A is not limited to this type of attachment. For example, the antenna wire 60 and the antenna connectors 42A can be attached by welding or similar methods.

[0046] In the present embodiment, one end 60A and the other end 60B of the antenna wire 60 are indeed attached by soldering after being wound around the antenna connector 42A. However, the method for connecting the antenna wire 60 to the antenna connectors 42A is not limited to this type of connection. For example, they can also be attached by soldering after a through-hole has been formed in the antenna connector 42A and either one end 60A or the other end 60B of the antenna wire 60 has been inserted into the through-hole.

[0047] Furthermore, although in the present embodiment the antenna connection part 42A is provided on the outer circumference of the circuit board 42, and the antenna wire 60 and the connector terminals 46 are electrically connected to each other by soldering one end 60A and the other end 60B of the antenna wire 60 to the antenna connection parts 42A, the method for connecting the antenna wire 60 and the connector terminals 46 is not limited to this type of connection. For example, a connection terminal (not shown) that is conductively connected to the connector terminals 46 can be provided on the circuit board 42, and one end of the connection terminal can be exposed through the opening 30C, allowing one end 60A and the other end 60B of the antenna wire 60 to be soldered to one end of the connection terminal. In this case, the connection terminals correspond to the antenna connection part of the present application.
