  As shown in FIG. 3, the sensor wire 21 includes a hollow insulator 22 and a pair of electrode wires 23 and 24 provided inside the hollow insulator 22. The hollow insulator 22 is formed of a transparent elastically deformable insulator (soft resin material, rubber, etc.) having insulating properties and resilience, and has a substantially cylindrical shape.

  The pair of electrode wires 23 and 24 held inside the hollow insulator 22 are arranged to be separated from each other in the circumferential direction inside the hollow insulator 22. One end portions in the longitudinal direction of the electrode wires 23 and 24 are projecting end portions 23 a and 24 a that project from the end portion on the power feeding connector 31 side in the longitudinal direction of the hollow insulator 22.

  In the present embodiment, the electrode wires 23 and 24 are provided in a spiral shape along the longitudinal direction inside the hollow insulator 22, and the hollow insulator 22 is provided at any position in the longitudinal direction of the hollow insulator 22. It faces the diametrical direction. Each electrode wire 23, 24 is partly embedded in the inner peripheral surface of the hollow insulator 22 in the circumferential direction.

  The resin connector portion 32 is formed so as to form an L shape from a first extension portion 32 a that is parallel to the sensor wire 21 and a second extension portion 32 b that extends in a direction orthogonal to the longitudinal direction of the sensor wire 21. ing. Each of the terminals 33 and 34 provided inside the resin connector portion 32 has an elongated linear shape and is bent along the L-shape of the resin connector portion 32. The terminals 33 and 34 are formed by bending a predetermined portion after punching a metal plate material into a predetermined shape by press working.

  The first ends 33a and 34a of the terminals 33 and 34 protrude from the first extension 32a toward the sensor wire 21 and are connected to the protruding ends 23a and 24a of the electrode wires 23 and 24 by welding, respectively. ing. An interposition part 32d extending from the first extension part 32a is interposed between the first end parts 33a and 34a of the terminals 33 and 34. An insulating portion 32e extends from the distal end portion of the interposed portion 32d, and the insulating portion 32e is inserted between the electrode wires 23 and 24 inside the hollow insulator 22.

  An opening portion 32 c that opens in a direction orthogonal to the longitudinal direction of the sensor wire 21 is formed in the second extension portion 32 b of the resin connector portion 32. The second ends 33b and 34b (ends opposite to the first ends 33a and 34a) of the terminals 33 and 34 are configured to be exposed from the opening 32c.

  A cylindrical heat-shrinkable tube 35 (covering member) is provided between the sensor wire 21 and the power supply connector 31 to cover the connection portion C between the electrode wires 23 and 24 and the terminals 33 and 34. One end of the heat shrinkable tube 35 in the longitudinal direction is extrapolated to the end of the sensor wire 21 in the longitudinal direction of the hollow insulator 22. On the other hand, the other end portion of the heat shrinkable tube 35 in the longitudinal direction is extrapolated to the first extension portion 32a of the power supply connector 31 and abutment provided on the side surface of the second extension portion 32b on the sensor wire 21 side. It is in contact with the portion 32f.

  In addition, a resistor 36 (diagnosis resistor) shown in FIG. 2 connected between the electrode wires 23 and 24 is connected to the longitudinal end portion (upper end portion in FIG. 1) of the hollow insulator 22 opposite to the power supply connector 31. Is provided.

  In the pressure-sensitive sensor 11 configured as described above, as shown in FIG. 1, the sensor wire 21 is fixed along the front end portion 5 a of the door panel 5 via the holding member 40. The power supply connector 31 at the lower end of the sensor wire 21 is attached to the front end 5a of the door panel 5 so that the opening 32c of the second extension 32b faces the inside of the door panel 5 (the vehicle rear side). The second extending portion 32 b is configured to enter the door panel 5. And the 2nd extension part 32b is connected to the external connector (illustration omitted) of the control part 41 arrange | positioned in the door panel 5. As shown in FIG.

  As shown in FIG. 2, the control unit 41 includes an energization detection unit 42 and a door ECU 43 electrically connected to the energization detection unit 42. The sensor wire 21 of the pressure-sensitive sensor 11 is connected to the control unit 41 via the power supply connector 31 and the external connector, whereby the electrode wire 23 is electrically connected to the energization detection unit 42 and the electrode The line 24 is connected to the ground GND (that is, grounded to the vehicle body 3).

  The energization detection unit 42 supplies current to the electrode wires 23 and 24 via the terminals 33 and 34 of the power supply connector 31. In a normal state where no pressing force is applied to the sensor line 21, the current supplied from the energization detection unit 42 to the electrode line 23 flows to the electrode line 24 through the resistor 36. On the other hand, when a pressing force that crushes the sensor wire 21 in the diametrical direction is applied, the hollow insulator 22 in the portion where the pressing force is applied is elastically deformed and the electrode wire 23 is accompanied by the elastic deformation of the hollow insulator 22. 24 are bent, and 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 42 to the electrode wire 23 flows through the electrode wire 24 without passing through the resistor 36. 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 42 detects the change in the current value at this time, thereby It detects that a pressing force has been applied. And when the energization detection part 42 detects the change of this electric current value, it outputs a pressure-sensitive signal to door ECU43. When the pressing force on the sensor wire 21 is removed, the hollow insulator 22 is restored, and the electrode wires 23 and 24 are also restored and become non-conductive.

  The door ECU 43 includes a ROM (Read only Memory), a RAM (Random access Memory), and the like and has a function as a microcomputer, and is supplied with power from a battery (not shown) of the vehicle 2. The door ECU 43 controls the slide actuator 6 based on various signals input from the operation switch 9, the position detection device 8, the energization detection unit 42, and the like.

Next, the operation of the electric sliding door device 1 configured as described above will be comprehensively described with reference to FIGS. 1 and 2.
When an open signal is input from the operation switch 9, the door ECU 43 drives the slide actuator 6 to open the door panel 5. The door ECU 43 recognizes the 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 43 counts the number of pulses of the position detection signal and recognizes the position of the door panel 5 based on the count value. And if the door panel 5 is arrange | positioned in the full open position Po which opens the entrance / exit 4 completely, door ECU43 will stop the slide actuator 6. FIG.

  On the other hand, when a close signal is input from the operation switch 9, the door ECU 43 drives the slide actuator 6 to close the door panel 5. When the door panel 5 is disposed at the fully closed position Pc where the doorway 4 is completely closed, the door ECU 43 stops the slide actuator 6. When the foreign matter X comes into contact with the sensor wire 21 arranged at the front end portion 5a of the door panel 5 and a pressing force is applied to the sensor wire 21 during the closing operation of the door panel 5, the hollow insulator 22 in the sensor wire 21 is applied. Is elastically deformed, the pair of electrode wires 23 and 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 is changed, the energization detection unit 42 outputs a pressure sensitive signal to the door ECU 43. When the pressure-sensitive signal is input, the door ECU 43 reverses the slide actuator 6 to open the door panel 5 by a predetermined distance, and then stops the slide actuator 6.

Next, the effect | action of the said embodiment is demonstrated according to Fig.4 (a)-(d) with the assembly method of the sensor wire 21 and the electric power feeding connector 31. FIG.
First, as shown in FIGS. 4 (a) and 4 (b), the heat-shrinkable tube starts from the longitudinal end on the side where the power supply connector 31 is provided with respect to the hollow insulator 22 of the sensor wire 21 before the power supply connector 31 is assembled. 35 is extrapolated (extrapolation step). At this time, the heat-shrinkable tube 35 is loosely fitted to the hollow insulator 22.

  Next, as shown in FIGS. 4B and 4C, the power feeding connector 31 is assembled to the sensor wire 21. At this time, the insulating portion 32 e of the power feeding connector 31 is inserted inside the hollow insulator 22. The terminals 33 and 34 are arranged on the radially inner sides of the protruding end portions 23a and 24a of the electrode wires 23 and 24, respectively.

  Thereafter, as shown in FIG. 4C, the first ends 33a and 34a of the terminals 33 and 34 and the projecting ends 23a and 24a of the electrode wires 23 and 24 are welded at the connection points C, respectively (connection process). . Thereby, the terminals 33 and 34 and the electrode wires 23 and 24 are electrically connected to each other.

  Next, as shown in FIGS. 4C and 4D, the heat-shrinkable tube 35 that is extrapolated to the sensor wire 21 in a loosely fitted state is moved to the power supply connector 31 side (covering step). At this time, the heat shrinkable tube 35 is moved until it abuts against the abutting portion 32 f of the power supply connector 31. That is, the heat-shrinkable tube 35 is positioned by abutting the heat-shrinkable tube 35 against the abutting portion 32f. Thereby, the heat shrinkable tube 35 is disposed at a position straddling the longitudinal end portion of the hollow insulator 22 of the sensor wire 21 and the first extending portion 32a of the power supply connector 31, and the electrode wire 23 is formed by the heat shrinkable tube 35. , 24 and terminals 33, 34 are covered.

  Next, the heat-shrinkable heat shrinkable tube 35 is heated as shown in FIG. 4 (d) and contracted as shown in FIG. Thereby, the inner peripheral surface of the heat-shrinkable tube 35 is brought into close contact with the outer peripheral surface of the hollow insulator 22 and the outer peripheral surface of the first extending portion 32a of the power supply connector 31 to ensure sealing performance. As a result, the infiltration of liquid into the connection portion C between the electrode wires 23 and 24 and the terminals 33 and 34 and the inside of the hollow insulator 22 is prevented. At this time, the end of the hollow insulator 22 is tightened due to the shrinkage of the heat shrinkable tube 35 and a force is generated in a direction in which the electrode wires 23 and 24 approach each other. Since the interposition part 32d of the resin connector part 32 is interposed between 24, the short circuit between the electrode wires 23 and 24 is prevented.

Next, characteristic effects of the present embodiment will be described.
(1) In the present embodiment, after the heat-shrinkable tube 35 is extrapolated from the longitudinal end of the sensor wire 21 on the side where the power supply connector 31 is provided, the electrode wires 23 and 24 and the terminals 33 and 34 are welded. Connect with. Next, the heat shrinkable tube 35 externally attached to the sensor wire 21 is moved to the power supply connector 31 side so as to straddle the sensor wire 21 and the power supply connector 31, and connected by the heat shrinkable tube 35. Cover location C. That is, before connecting the power supply connector 31 to the sensor wire 21, the heat shrinkable tube 35 is extrapolated from the longitudinal end portion (connection side end portion) on the side where the power supply connector is provided with respect to the sensor wire 21. Accordingly, it is not necessary to extrapolate the heat-shrinkable tube 35 from the end of the sensor wire 21 opposite to the connection-side end with the power supply connector 31 and to move the entire length of the sensor wire 21 to the connection-side end. The heat shrinkable tube 35 can be easily attached.

  (2) In the present embodiment, the power feeding connector 31 has an abutting portion 32f that can come into contact with the heat-shrinkable tube 35 in the longitudinal direction of the sensor wire 21, and the heat-shrinkable tube 35 is abutted against the abutting portion 32f in the covering step. Move until it hits. Accordingly, the heat shrinkable tube 35 can be mounted more easily because the heat shrinkable tube 35 can be positioned in the longitudinal direction by abutting the heat shrinkable tube 35 against the abutting portion 32f of the power supply connector 31. It becomes. Further, in the configuration in which the abutting portion 32f is provided on the power feeding connector 31 (L-shaped configuration in the present embodiment), the power feeding connector 31 is connected to the sensor wire 21 and the end on the power feeding connector 31 side. It is difficult to extrapolate the heat shrinkable tube 35. For this reason, the effect of facilitating the mounting of the heat-shrinkable tube 35 by extrapolating the heat-shrinkable tube 35 from the connection side end of the sensor wire 21 before connecting the power supply connector 31 to the sensor wire 21 is more remarkable. It becomes.

  (3) In the present embodiment, the heat-shrinkable tube 35 is heated and shrunk after the covering step and is fixed to the sensor wire 21 and the power supply connector 31. As a result, the heat-shrinkable heat-shrinkable tube 35 is brought into close contact with the sensor wire 21 and the power supply connector 31 to ensure a sealing property, so that the liquid to the connection portion C between the electrode wires 23 and 24 and the terminals 33 and 34 Intrusion can be prevented. Moreover, since it becomes possible to extrapolate the heat-shrinkable tube 35 to the sensor wire 21 in the extrapolation process in the extrapolation step, it becomes possible to attach the heat-shrinkable tube 35 more easily.

  (4) In the present embodiment, the power feeding connector 31 has the resin connector portion 32 formed with the terminal as an insert product, and the abutting portion 32f is formed in the resin connector portion 32.

The other O-ring 73 is interposed between the cylindrical portion 71 and the first extending portion 32 a of the power supply connector 31. Also with such a configuration, the gap between the sensor wire 21 and the power supply connector 31 is sealed, and the infiltration of liquid into the connection portion C and the inside of the hollow insulator 22 can be prevented.
