JP 2007-176322 A

  By the way, in the foreign matter detection sensor described above, not only the sensor unit but also the lead wire folded back in a substantially U shape at the lower end of the sensor unit is within the range of the door panel in the vertical direction at the end of the door panel. Be placed. Therefore, the range in which the sensor unit is arranged is narrowed in the longitudinal direction of the sensor unit by the amount of the lead wire folded back in a substantially U shape at the lower end of the sensor unit, and as a result, the length of the sensor unit is shortened. End up. Since the foreign object detection sensor detects a foreign object that has contacted the sensor unit, there is a problem that when the length of the sensor unit is shortened, the range in which the foreign object is detected becomes narrow in the longitudinal direction of the sensor unit. It was.

  This invention is made | formed in view of such a situation, The objective is to provide the foreign material detection sensor which can make a detection range wide in the longitudinal direction of a sensor part.

  A foreign object detection sensor that solves the above problems is a long hollow insulator having elasticity and insulating properties, and a plurality of electrode wires that are spaced apart from each other inside the hollow insulator. A foreign matter detection sensor for detecting the foreign matter by receiving an external force from the foreign matter and elastically deforming the sensor portion, wherein the sensor portion is pulled out from one end portion in the longitudinal direction of the hollow insulator. It is electrically connected to the electrode wire, extends from the electrode connection portion, which is a connection portion with the electrode wire, in a direction intersecting the longitudinal direction of the sensor portion, and further toward the other end side in the longitudinal direction of the sensor portion. A power supply member having a direction changing portion extending in the direction and one end portion in the longitudinal direction of the sensor portion, and sealing the inside of the electrode connecting portion, the direction changing portion, and the longitudinal end portion of the hollow insulator inside Sealed member It is equipped with a.

  According to this configuration, the power supply member connected to the electrode wire extends from the electrode connection portion, which is a connection portion between the power supply member and the electrode wire, in a direction intersecting the longitudinal direction of the sensor portion, and further the length of the sensor portion. It has the direction conversion part extended in the direction which goes to the other end part side of a direction. That is, the power feeding member extends in a direction intersecting with the longitudinal direction of the sensor portion immediately after being connected to the electrode wire, and further extends toward the other end portion side in the longitudinal direction of the sensor portion. Therefore, when the power feeding member is shaped so as to extend toward the other end in the longitudinal direction of the sensor part at one end in the longitudinal direction of the foreign object detection sensor, the power feeding member is sealed in the longitudinal direction of the sensor part. It is suppressed that it protrudes more. Further, the length of the portion of the power supply member that protrudes in the longitudinal direction of the sensor portion from one end in the longitudinal direction of the hollow insulator can be kept short in the longitudinal direction of the sensor portion. As a result, the length of the portion of the power supply member that protrudes in the longitudinal direction of the sensor portion from the longitudinal end of the hollow insulator can be kept short in the longitudinal direction of the sensor portion. Can be long. Moreover, since the direction change part is sealed inside the sealing member, it is suppressed that the electric power feeding member protrudes rather than the sealing member in the longitudinal direction of a sensor part. For this reason, the length of the sensor portion in the longitudinal direction is suppressed by the power supply member. Accordingly, in the foreign matter detection sensor, the foreign matter detection range can be widened in the longitudinal direction of the sensor unit.

The bend portion which is arranged adjacent to each other and is bent so that the direction in which the power feeding member extends is a direction toward the other end portion side in the longitudinal direction of the sensor portion, is configured to include the terminal. Preferably, the bent portion is formed by connecting a tip end portion of the lead wire disposed so as to intersect the longitudinal direction of the terminal to the terminal.

  According to this configuration, the bent portion can be easily formed when the tip of the lead wire is connected to the terminal. Further, since the terminal is arranged so that the short direction of the terminal coincides with the longitudinal direction of the sensor part, the terminal and the sealing member for sealing the terminal inside are downsized in the longitudinal direction of the sensor part. be able to. And the sensor part can be made longer in the longitudinal direction as much as the sealing member is downsized in the longitudinal direction. As a result, in the foreign matter detection sensor, the foreign matter detection range can be made wider in the longitudinal direction of the sensor unit.

  In the foreign matter detection sensor, the sealing member has an attachment leg that protrudes outward from the outer peripheral surface of the hollow insulator and is attached to a bracket for attaching the sensor portion to an attachment location, and is a part of the power supply member Is preferably embedded in the mounting leg.

According to this configuration, the mounting leg can be reinforced by the power supply member embedded in the mounting leg.
In the foreign matter detection sensor, the attachment leg has an attachment engagement portion that engages with the bracket, and a part of the power feeding member is located behind the attachment engagement portion inside the attachment leg. preferable.

  According to this configuration, the back portion of the mounting engagement portion, which is in the vicinity of the mounting engagement portion in the mounting leg, is a portion where a load is easily applied when the mounting leg is mounted on the bracket. And since the electric power feeding member is embed | buried under the back part of the attachment engaging part which is a part which a load tends to apply in an attachment leg, an attachment leg can be reinforced more effectively.

In the foreign matter detection sensor, it is preferable that the attachment engaging portion has a concave shape that is recessed so as to narrow the width of the attachment leg.
According to this configuration, a part of the power feeding member is embedded in a portion where the width of the mounting leg is narrowed by forming the recessed mounting engagement portion on the mounting leg. Therefore, the vicinity of the portion where the concave mounting engagement portion is formed on the mounting leg can be more effectively reinforced by the power feeding member.

  According to the foreign matter detection sensor of the present invention, the detection range can be widened in the longitudinal direction of the sensor portion.

After the two lead wires 52 and 53 extending from the mounting leg 62 of the sealing member 34 extend in parallel to the sensor portion 21 toward the first end portion 22d (right side in FIG. 5B). , Is drawn into the door panel 5. As shown in FIG. 2, one of the two lead wires 52 and 53 drawn into the door panel 5 is electrically connected to the energization detection unit 14 inside the door panel 5. . Further, of the two lead wires 52 and 53, the other lead wire 53 is connected to the ground GND inside the door panel 5 (that is, grounded to the vehicle body 3).

  As shown in FIGS. 1 and 2, the energization detection unit 14 is disposed inside the door panel 5. The energization detection unit 14 supplies current to the electrode wire 23. In a normal state in which an external force such as a pressing force is not applied to the sensor unit 21, the current supplied from the energization detection unit 14 to the electrode wire 23 flows to the electrode wire 24 through the resistor 28. On the other hand, when an external force that crushes the sensor unit 21 is applied, the hollow insulator 22 in the portion where the external force is applied is elastically deformed, and the electrode wires 23 and 24 are bent along with the elastic deformation of the hollow insulator 22. Then, the electrode wire 23 and the electrode wire 24 come into contact with each other and are short-circuited. Then, the current supplied from the energization detection unit 14 to the electrode wire 23 flows to the electrode wire 24 without passing through the resistor 28. Therefore, for example, when a current is supplied to the electrode wire 23 at a constant voltage, the current value changes. Therefore, the energization detection unit 14 detects the change in the current value at this time, thereby detecting the sensor unit. Detects foreign matter that has come into contact with And when the electricity supply detection part 14 detects the change of this electric current value, ie, detects the foreign material which contacted the foreign material detection sensor 13, it will output a foreign material detection signal to door ECU71 mentioned later. In addition, when the external force with respect to the sensor part 21 is removed, the hollow insulator 22 will be restored, and the electrode wires 23 and 24 will also be restored and become non-conductive.

  The electric back door device 2 includes a door ECU 71 that controls the opening / closing operation of the door panel 5 by the actuator 6 inside the door panel 5. The door ECU 71 includes a ROM (Read only Memory), a RAM (Random access Memory), and the like, has a function as a microcomputer, and is supplied with power from a battery (not shown) of the vehicle 1. The door ECU 71 supplies a current to the energization detection unit 14 that is electrically connected to the door ECU 71. The door ECU 71 controls the actuator 6 based on various signals input from the operation switch 9, the position detection device 8, the energization detection unit 14, and the like.

Next, the operation of the electric back door device 2 configured as described above will be comprehensively described.
When an open signal is input from the operation switch 9, the door ECU 71 drives the actuator 6 to open the door panel 5. The door ECU 71 recognizes the rotational position of the door panel 5 based on the position detection signal input from the position detection device 8. In the present embodiment, the door ECU 71 counts the number of pulses of the position detection signal, and recognizes the rotational position of the door panel 5 based on the count value. When the door panel 5 is disposed at the fully closed position, the door ECU 71 stops the actuator 6.

  On the other hand, when a close signal is input from the operation switch 9, the door ECU 71 drives the actuator 6 to close the door panel 5. When the door panel 5 is disposed at the fully closed position, the door ECU 71 stops the actuator 6. In addition, during the closing operation of the door panel 5, if a foreign object comes into contact with the sensor unit 21 of the foreign object detection sensor 13 and an external force is applied to the sensor unit 21, the hollow insulator 22 is elastically deformed in the foreign object detection sensor 13. As a result, the electrode wire 23 and the electrode wire 24 come into contact with each other and are short-circuited. As a result, since the current value of the current supplied to the electrode wire 23 changes, the energization detection unit 14 outputs a foreign object detection signal to the door ECU 71. When the foreign object detection signal is input, the door ECU 71 reverses the actuator 6 to open the door panel 5 by a predetermined amount and then stops the actuator 6.

Next, the operation of the foreign matter detection sensor 13 of this embodiment will be described.
As shown in FIG. 5B, the lead wire 52 constituting one power supply member 33 includes a direction changing portion 56 having a bent portion 57, so that one of them is orthogonal to the sensor portion 21 from the electrode connecting portion P <b> 1. After extending in the direction (in this embodiment, the direction orthogonal to the sticking surface 22a and toward the front side of the sticking surface 22a), the sensor part 21 is parallel to the first end 22d side of the hollow insulator 22. It extends to make. Similarly, the lead wire 53 constituting the other power supply member 33 has a direction changing portion 56 provided with a bent portion 57, so that one direction orthogonal to the sensor portion 21 from the electrode connecting portion P1 (in this embodiment, After extending in the direction orthogonal to the sticking surface 22a and toward the front side of the sticking surface 22a), it extends toward the first end 22d side of the hollow insulator 22 so as to be parallel to the sensor part 21. . Therefore, in the foreign matter detection sensor 13 fixed to the door panel 5 via the bracket 12, the lead wires 52 and 53 drawn from the sealing member 34 are connected to the longitudinal end of the sensor portion 21 on the first end portion 22 d side. Even if the lead wires 52 and 53 are shaped so as to extend toward the right side (the right side in FIG. 5B), the lead wires 52 and 53 in the vicinity of the end portion in the longitudinal direction on the second end portion 22e side of the sensor portion 21 It does not protrude from the sealing member 34 in the longitudinal direction of the sensor unit 21.

As described above, the present embodiment has the following effects.
(1) The power supply member 33 connected to the electrode wire 23 extends from the electrode connection portion P1 which is a connection portion between the power supply member 33 and the electrode wire 23 in a direction orthogonal to the longitudinal direction of the sensor portion 21. The direction change part 56 extended in the direction which goes to the other end part side of the longitudinal direction of the part 21 is provided. Similarly, the power supply member 33 connected to the electrode wire 24 extends from the electrode connection portion P1 which is a connection portion between the power supply member 33 and the electrode wire 24 in a direction orthogonal to the longitudinal direction of the sensor portion 21, and further the sensor. The direction change part 56 extended in the direction which goes to the other end part side of the longitudinal direction of the part 21 is provided. That is, each power supply member 33 extends in a direction orthogonal to the longitudinal direction of the sensor unit 21 immediately after being connected to the electrode wires 23, 24, and further extends toward the other end in the longitudinal direction of the sensor unit 21. Yes. Accordingly, each power supply member 33 is shaped so as to extend toward the other end portion in the longitudinal direction of the sensor portion 21 at one end portion in the longitudinal direction of the foreign object detection sensor 13 (end portion on the second end portion 22e side). In this case, it is suppressed that each power supply member 33 protrudes from the sealing member 34 in the longitudinal direction of the sensor unit 21. Further, in each power supply member 33, the length of the portion protruding in the longitudinal direction of the sensor portion 21 is shorter in the longitudinal direction of the sensor portion 21 than the longitudinal end of the hollow insulator 22 (end on the second end portion 22 side). Can be suppressed. As a result, the length of the portion of each power supply member 33 protruding in the longitudinal direction of the sensor part 21 from the one end in the longitudinal direction of the hollow insulator 22 can be kept short in the longitudinal direction of the sensor part 21. The part 21 can be elongated in the longitudinal direction. In addition, since the direction changing portion 56 is sealed inside the sealing member 34, each power feeding member 33 is prevented from protruding beyond the sealing member 34 in the longitudinal direction of the sensor portion 21. Therefore, the length of the sensor unit 21 in the longitudinal direction is suppressed by each power supply member 33. For these reasons, in the foreign matter detection sensor 13, the foreign matter detection range can be widened in the longitudinal direction of the sensor unit 21.

  (2) One power supply member 33 is disposed so as to be adjacent to one end portion in the longitudinal direction of the sensor unit 21 and is electrically connected to the one terminal 51 to which the electrode wire 23 is electrically connected. The lead wire 52 is made up of. The other power supply member 33 is disposed adjacent to one end in the longitudinal direction of the sensor unit 21 and is electrically connected to the other terminal 51 to which the electrode wire 24 is electrically connected. Lead wire 53. Therefore, since the electrode wires 23 and 24 are electrically connected to the terminal 51, the connection between the electrode wires 23 and 24 and the power feeding member 33 can be easily performed.

(3) The bent portion 57 is formed by bending the lead wires 52 and 53. In this manner, the bent portion 57 can be easily formed by bending the lead wires 52 and 53.
(4) The mounting leg 62 can be reinforced by the power supply member 33 embedded in the mounting leg 62.

  (5) The back portion of the attachment engaging portion 63 that is in the vicinity of the attachment engaging portion 63 in the attachment leg 62 is a portion where a load is easily applied in a state where the attachment leg 62 is attached to the bracket 12. And since the electric power feeding member 33 is embed | buried under the back part of the attachment engaging part 63 which is a part which is easy to apply a load in the attachment leg 62, the attachment leg 62 can be reinforced more effectively.

  (6) A part of the power feeding member 33 is embedded in a portion of the mounting leg 62 whose width is narrowed by the formation of the concave mounting engagement portion 63. Accordingly, the power supply member 33 can more effectively reinforce the vicinity of the portion of the mounting leg 62 where the concave mounting engagement portion 63 is formed.

In addition, you may change the said embodiment as follows.
In the above embodiment, the mounting engagement portion 63 has a concave shape that is recessed so as to narrow the width of the mounting leg 62, but the shape of the mounting engagement portion 63 is not limited to this. For example, the attachment engaging portion 63 may have a shape protruding in the width direction of the attachment leg 62. In addition, the edge part of the longitudinal direction of the bracket 12 is made into the shape which the attachment engaging part 63 can engage.

  In the above embodiment, a part of the power feeding member 33 is located behind the attachment engaging portion 63 inside the attachment leg 62. However, a part of the power supply member 33 embedded in the mounting leg 62 does not necessarily have to be located on the back of the mounting engagement portion 63.

  In the above embodiment, the mounting leg 62 has a pair of mounting engaging portions 63. However, the mounting leg 62 may have a configuration including only one mounting engaging portion 63. Further, the mounting leg 62 does not necessarily have to include the mounting engaging portion 63.

  In the above embodiment, the portion of the sealing member 34 that protrudes outward from the outer peripheral surface of the hollow insulator 22 is the mounting leg 62 that is attached to the bracket 12. However, the portion of the sealing member 34 that protrudes outward from the outer peripheral surface of the hollow insulator 22 (the portion that protrudes to the front side of the sticking surface 22 a) does not necessarily have to be attached to the bracket 12.

  In the above embodiment, the foreign object detection sensor 13 is attached to the peripheral edge (attachment location) of the door panel 5 via the bracket 12. However, the foreign matter detection sensor 13 may be directly attached to the peripheral edge of the door panel 5 without using the bracket 12. The foreign matter detection sensor 13 may be attached to the peripheral portion of the bracket 12 or the door panel 5 by another method, such as adhesion, in addition to sticking with the double-sided tape 15.

  -Like the example shown to Fig.6 (a) and FIG.6 (b), a direction change part may be comprised including a terminal. In FIGS. 6A and 6B, the same reference numerals are given to the same components as those in the above embodiment. The foreign object detection sensor 81 shown in FIGS. 6A and 6B includes two power supply members 82 instead of the two power supply members 33. One power supply member 82 includes one terminal 91 and one lead wire 52. The other power supply member 82 is composed of another terminal 91 and the other lead wire 53. Each terminal 91 includes a terminal main body 92 having a rectangular plate shape having a short side direction and a long side direction, and a first connection piece 93 and a second connection piece 94 formed integrally with the terminal main body 92. . The length of each terminal main body 92 in the longitudinal direction is formed longer than the length in the direction perpendicular to the sticking surface 22 a in the cross section perpendicular to the longitudinal direction of the hollow insulator 22. The terminal support portion 101 of the support member 32 has a rectangular plate shape that is slightly larger than the terminal main body 92, and the two terminal main bodies 92 have a longitudinal direction, a short direction, and a thickness direction, respectively. The terminal support portion 101 is disposed on both end faces in the thickness direction so as to coincide with the longitudinal direction, the short side direction, and the thickness direction of the terminal support portion 101. The terminal support portion 101 insulates the two terminals 91 from each other and supports the two terminals 91 so as to form a double structure in which the two terminals 91 overlap in the thickness direction. Further, in each terminal 91, the first connection piece 93 extends from one end of the terminal main body 92 in the longitudinal direction (the upper end in FIG. 6B), while the second connection piece 94 extends from the length of the terminal main body 92. It extends from the other end portion in the direction (the lower end portion in FIG. 6B). The first connection piece 93 and the second connection piece 94 have a rectangular plate shape.

  In addition, a spacer 42 is provided at a portion of the end portion of the terminal support portion 101 in the longitudinal direction (the end portion on the first connection piece 93 side) facing the second end portion 22e of the hollow insulator 22 and the sensor portion 21 in the longitudinal direction. It is integrally formed. The support member 32 is assembled to the hollow insulator 22 in a state in which a portion on the distal end side of the spacer 42 is inserted into the hollow hole 22b from the second end 22e side of the hollow insulator 22. Then, in a state where the support member 32 is attached to the hollow insulator 22 by inserting the spacer 42 into the hollow hole 22 b, the two terminals 91 are arranged so that the short direction thereof coincides with the longitudinal direction of the sensor unit 21. In addition, it is arranged adjacent to the second end 22e of the hollow insulator 22 so that its longitudinal direction is orthogonal to the longitudinal direction of the sensor portion 21. Each terminal 91 has a length in one direction orthogonal to the longitudinal direction of the sensor unit 21 (in this example, a direction orthogonal to the bonding surface 22a), and the same bonding surface than the back side of the bonding surface 22a. 22a is long on the front side.

  The center electrodes 25 of the two electrode wires 23 and 24 drawn from the second end 22 e of the hollow insulator 22 are disposed on both sides in the thickness direction of the terminal support portion 101. Further, the opposing terminal 91 and the center electrode 25 are electrically connected to both sides of the terminal support portion 101 in the thickness direction. Specifically, the first connection piece 93 of each terminal 91 is folded back so as to overlap the terminal main body 92, and the center electrode 25 disposed on the terminal main body 92 is sandwiched between the terminal main body 92. The center electrode 25 sandwiched between the terminal body 92 and the first connection piece 93 is electrically connected to the terminal 51 by soldering. In FIG. 6B, the solder 111 that electrically connects the center electrode 25 to the terminal 91 is illustrated by a two-dot chain line. Thus, the center electrode 25 of the electrode wires 23 and 24 is electrically connected to one end side of the two terminals 91 in the longitudinal direction. That is, the electrode connection portion P1 that is a connection portion between each terminal 91 and the center electrode 25 of each electrode wire 23, 24 is the same as the end portion in the longitudinal direction of the sensor portion 21 (the end portion on the second end portion 22e side). It is formed at one end in the longitudinal direction of each terminal 51 adjacent in the longitudinal direction of the sensor unit 21. And each terminal 91 is the direction orthogonal to the longitudinal direction of the sensor part 21 from the electrode connection part P1 in the direction conversion part 83 of each electric power feeding member 82 (in this example, it is a direction orthogonal to the bonding surface 22a, and bonding). A portion extending to the front side of the surface 22a is formed.

  Further, the two lead wires 52 and 53 are connected to the other end portion in the longitudinal direction of each terminal 91 (the end portion on the second connection piece 94 side). The metal wire 54 exposed at the tip of each of the lead wires 52 and 53 is disposed so as to intersect the longitudinal direction of the terminal 91 with respect to the terminal 91 to be connected. Furthermore, the lead wires 52 and 53 are arranged so as to extend from the terminal 91 to the other end portion side (first end portion 22 d side) in the longitudinal direction of the sensor unit 21. Then, the second connecting piece 94 of each terminal 91 is folded back so as to overlap the terminal main body 92 and the leading ends of the lead wires 52 and 53 disposed on the terminal main body 92 are sandwiched between the terminal main bodies 92. It is out. The leading ends of the lead wires 52 and 53 sandwiched between the terminal main body 92 and the second connection piece 94 are electrically connected to the terminal 91 by soldering. In FIG. 6B, the solder 112 that electrically connects the lead wires 52 and 53 to the terminal 51 is indicated by a two-dot chain line. Thus, by connecting the lead wires 52 and 53 to each terminal 91, a bent portion 84 is formed by the leading end portion of each lead wire 52 and 53 and the other end portion of the terminal 91 to which the lead wires 52 and 53 are respectively connected. Is formed. The bent portion 84 is bent such that a portion extending from the bent portion 84 of the power supply member 82 to the side opposite to the electrode connecting portion P <b> 1 extends in the direction toward the other end portion side in the longitudinal direction of the sensor portion 21. In this example, a bent portion 84 that is bent at a substantially right angle is formed by the tip end portions of the lead wires 52 and 53 and the other end portion of the terminal 91 to which the lead wires 52 and 53 are connected. In each power supply member 82, the direction changing portion 83 having the bent portion 84 corresponds to a portion embedded in the sealing member 34.

  If it does in this way, when connecting the tip part of lead wires 52 and 53 to corresponding terminal 91, bent part 84 can be formed easily. In addition, since each terminal 91 is arranged so that the short direction of each terminal 91 coincides with the longitudinal direction of the sensor unit 21, each terminal 91 and the sealing member 34 that seals each terminal 91 inside is used as a sensor. The size can be reduced in the longitudinal direction of the portion 21. And the sensor part 21 can be lengthened by the longitudinal direction by the part which miniaturized the sealing member 34 in the longitudinal direction. As a result, in the foreign matter detection sensor 81, the foreign matter detection range can be made wider in the longitudinal direction of the sensor unit 21.

  In the above embodiment, the lead wires 52 and 53 are connected to the same position on the terminal 51 as the position where the center electrode 25 of the electrode wires 23 and 24 is connected. However, the lead wires 52 and 53 may be connected to a position shifted in the longitudinal direction of the sensor unit 21 from the position where the center electrode 25 of the electrode wires 23 and 24 is connected on the terminal 51.

  In the above embodiment, one power supply member 33 is configured by one terminal 51 and one lead wire 52, but may be configured by only the lead wire 52. Similarly, the other power supply member 33 is composed of the other terminal 51 and the other lead wire 53, but may be composed of only the lead wire 53. In this case, the tip of the center electrode 25 of the electrode wire 23 and the tip of the metal wire 54 of the lead wire 52 are directly electrically connected, and the tip of the center electrode 25 of the electrode wire 24 and the lead wire 53 are connected. The tip of the metal wire 54 is directly electrically connected. Therefore, the terminal processing unit 31 does not include the support member 32 and the terminal 51. Therefore, since the number of parts of the foreign object detection sensor 13 is reduced, the manufacturing cost can be reduced.

  In the above-described embodiment, the bent portion 57 includes the sensor portion 21 and the portion on the opposite side of the electrode connecting portion P <b> 1 from the bent portion 57 of each power supply member 33 toward the first end 22 d side of the hollow insulator 22. It is bent so as to be parallel. However, the bent portion 57 is bent so that the extending direction of the portion on the opposite side of the electrode connecting portion P <b> 1 from the bent portion 57 in the power supply member 33 is the direction toward the other end portion side in the longitudinal direction of the sensor portion 21. I just need it.

  In the above embodiment, the direction changing unit 56 includes the bent portion 57, but the bent portion 57 does not necessarily have to be provided. In this case, for example, the direction conversion unit 56 extends from the electrode connection unit P1 in a direction intersecting the longitudinal direction of the sensor unit 21, and further on the other end side in the longitudinal direction of the sensor unit 21 (on the first end 22d side). It may extend linearly within the sealing member 34 from the electrode connecting portion P1 to the end surface 62a of the mounting leg 62 so as to extend in the direction toward the front.

  In the above embodiment, the direction changing portion 56 extends from the electrode connecting portion P1 in a direction orthogonal to the longitudinal direction of the sensor portion 21, and further parallel to the sensor portion 21 toward the first end 22d side of the hollow insulator 22. It extends to make. However, the direction in which the direction changing unit 56 extends is not limited to this. The direction converting portion 56 extends from the electrode connecting portion P1 in a direction intersecting with the longitudinal direction of the sensor portion 21, and further the other end portion side in the longitudinal direction of the sensor portion 21 (the direction changing portion 56 in the sensor portion 21 is provided). It suffices if it extends in the direction toward the opposite end side). Even if it does in this way, the effect similar to (1) of the said embodiment can be acquired.

  In the above embodiment, a part of the insulating film 55 of each lead wire 52, 53 is embedded in the sealing member 34, but only a part of the insulating film 55 is not embedded in the sealing member 34 but only the metal wire 54. May be embedded in the sealing member 34. The insulating coating 55 is generally formed of a resin material. Therefore, by burying a part of the insulating film 55 in the sealing member 34 made of a resin material, for example, even when the terminal processing unit 31 is exposed to a high temperature and the resin material expands, the linear expansion coefficient It is possible to suppress a decrease in hermeticity between the sealing member 34 and the lead wires 52 and 53 due to a difference in (volume expansion coefficient).

The number of power supply members 33 provided in the foreign object detection sensor 13 may be appropriately changed according to the number of electrode wires 23 and 24.
-The shape of the sealing member 34 is not restricted to the thing of the said embodiment. The sealing member 34 only needs to have a shape that seals the electrode connecting portion P1, the direction changing portion 56, the bent portion 57, and one end portion in the longitudinal direction of the hollow insulator 22 inside. For example, the sealing member 34 is a cover that is attached to the outer periphery of the support member 32 so that the electrode connecting portion P1, the direction changing portion 56, the bent portion 57, and one end of the hollow insulator 22 in the longitudinal direction are accommodated therein. It may be in a shape.

  In the above embodiment, the straight line L1 passing through the centers of the electrode wires 23 and 24 is parallel to the width direction of the sticking surface 22a. However, the straight line L1 is not necessarily parallel to the width direction of the sticking surface 22a. For example, the straight line L1 may be parallel to a direction orthogonal to the longitudinal direction of the sensor unit 21. That is, the electrode wires 23 and 24 may be drawn from the second end 22e of the hollow insulator 22 so that the straight line L1 is parallel to the direction orthogonal to the longitudinal direction of the sensor portion 21 on the end face 22f. .

In the above embodiment, the sensor unit 21 includes the two electrode wires 23 and 24. However, the number of electrode wires provided in the sensor unit 21 is not limited to two and may be a plurality.
In the above embodiment, the electrode wires 23 and 24 extend spirally in the longitudinal direction of the hollow insulator 22. However, the electrode wires 23 and 24 may extend linearly along the longitudinal direction of the hollow insulator 22.
