  However, according to the technique disclosed in Patent Document 1, it is necessary to hold the connector with the connector holding portion. For this reason, it is necessary to use a dedicated inspection device for each type of connector, and the inspection cost increases due to an increase in design cost and manufacturing cost of the inspection device.

  In addition, the operation of inserting the terminal into the connector is carried out in one step of the line for manufacturing the wire harness. Depending on the manufacturing line, it is difficult to incorporate the terminal insertion state inspection device due to space limitations. There is a case.

  Hereinafter, the terminal insertion state inspection apparatus according to the embodiment will be described. FIG. 1 is a schematic front view showing the terminal insertion state inspection device 20, and FIG. 2 is a partial schematic side view showing the terminal insertion state inspection device 20.

  The terminal insertion state inspection device 20 is a device for performing a tensile test of the terminal 14 inserted into the connector 10.

  That is, in the manufacturing process of the wire harness assembled to the vehicle, an operator can perform an operation of inserting the terminals 14 attached to the ends of the plurality of electric wires 16 constituting the wire harness into the connector 10. is there. The connector 10 is a substantially rectangular parallelepiped member formed of resin or the like. The connector 10 is formed with hole-like cavities 12 into which terminals 14 can be inserted and connected, arranged vertically and horizontally (see FIGS. 5 and 6). Each cavity 12 opens to the back side of the connector 10, and the terminal 14 is inserted into the cavity 12 from the back side of the connector 10. In inserting the terminal 14 into the cavity 12, it is necessary to avoid a state in which the terminal 14 is only partially inserted into the cavity 12 (half-inserted state). Then, it is confirmed whether the terminal 14 is reliably inserted in the cavity 12 by pulling the electric wire 16 to which the inserted terminal 14 is connected. The terminal insertion state inspection device 20 is configured as a device for performing such confirmation.

  The terminal insertion state inspection device 20 includes a mounting unit 30 and a tensile force detection unit 40.

  The mounting portion 30 is configured to be mountable on a hand. Here, the mounting portion 30 is formed in a shape that can be mounted so as to cover the entire hand 22, that is, a glove shape. The mounting portion 30 is made of a material similar to a general glove, such as resin, leather, cloth, and wool. The mounting portion 30 includes a palm cover portion 32 that covers the palm and back of the hand 22 and a finger that extends outward from the palm cover portion 32 and covers each finger of the hand 22 (only the index finger 23 is shown in FIG. 2). Cover portions 33 to 37 are provided. The space in the palm cover part 32 and the space in the finger cover parts 33 to 37 communicate with each other, and each finger is covered while the palm and the back of the hand 22 are accommodated in the palm cover part 32. The housing portion 30 can be mounted on the manpower 22 by being accommodated in the portions 33 to 37. The finger cover 33 covers the thumb, the finger cover 34 covers the index finger 23, the finger cover 35 covers the middle finger, the finger cover 36 covers the ring finger, and the finger cover 37 covers the little finger.

  The pulling force detection unit 40 is supported by the mounting unit 30 so as to be located in at least one of the two work portions in which the electric wire 16 extending from the terminal 14 or the connector 10 can be inserted in the manpower 22.

  Here, when an operation of pulling the electric wire 16 from the connector 10 is assumed, it is easiest to sandwich the electric wire 16 or the connector 10 between the thumb and the index finger. For this reason, the two working parts are assumed to be the thumb belly and the index finger belly. The pulling force detection unit 40 is supported by the mounting unit 30 so as to be located on the surface of the abdomen of the index finger, which is one of the abdomen of the thumb and the index finger. More specifically, the tensile force detection unit 40 is attached to the surface of the portion of the mounting portion 30 that covers the index finger 23 of the finger cover portion 34 that covers the index finger 23.

  The pulling force detection unit 40 is configured to detect a physical quantity corresponding to the pulling force by the electric wire 16 or the connector 10 sandwiched between two sandwiching work parts and output the detection result. Here, a sheet-type shear force sensor is used as the tensile force detection unit 40. The sheet-type shear force sensor outputs a detection result corresponding to the shear force in at least one direction orthogonal to the thickness direction. As such a sheet-type shear force sensor, as is well known, a sheet-like shear force sensor in which a fine strain gauge or a fine piezoelectric element is incorporated can be used. The sheet-like tensile force detection unit 40 is fixed to the surface of the finger cover 34 with an adhesive or the like. Since the pulling force is distributed and received by the pulling force detection unit 40 on the index finger 23 side and the thumb, the pulling force detected by the pulling force detection unit 40 actually acts on the electric wire 16 or the connector 10. This is the pulling force obtained by subtracting the force received by the thumb from the pulling force. That is, the pulling force detection unit 40 does not need to detect the pulling force itself actually acting on the electric wire 16 or the connector 10, and may be any unit that detects a physical quantity corresponding to the pulling force. Here, the pulling force will be described as meaning not only the pulling force actually acting on the electric wire 16 or the connector 10 but also a force corresponding to the pulling force actually acting.

  FIG. 3 is a block diagram showing an electrical configuration of the terminal insertion state inspection device 20. As shown in FIGS. 1 and 3, a determination unit 50 and a notification unit 60 are incorporated in the terminal insertion state inspection device 20. The determination unit 50 and the notification unit 60 are attached to the mounting unit 30 by an adhesive or the like, and between the determination unit 50 and the tensile force detection unit 40 by an electric wire W or the like disposed along the mounting unit 30. And the determination part 50 and the alerting | reporting part 60 are electrically connected.

  The determination unit 50 is configured to perform pass / fail determination of the tensile test of the terminal 14 based on the detection result of the tensile force detection unit 40 and a predetermined determination criterion value for acceptance.

  More specifically, the determination unit 50 is configured by, for example, a microprocessor including the storage unit 52. The determination unit 50 is configured to be able to execute various processes in accordance with instructions defined in a program stored in the storage unit 52. The storage unit 52 includes a ROM (Read Only Memory), a RAM (Random Access Memory), a rewritable nonvolatile memory (EPROM (Erasable Programmable ROM), flash memory, etc.), and the like. The storage unit 52 stores a first threshold value and a second threshold value, which are criteria for pass / fail determination, in addition to a program for determining pass / fail, and is also used as a work area for the microprocessor.

  The storage unit 52 stores a first threshold value and a second threshold value. The first threshold value and the second threshold value are values set and stored in advance.

  The first threshold value is data that serves as a criterion for determining whether or not a pulling load can be accepted when the electric wire 16 is pulled from the connector 10. That is, when the terminal 14 is insufficiently inserted into the cavity 12, or when the locking portion in the cavity 12 is not normally hooked on the terminal 14, the terminal 14 is pulled out with a relatively small pulling force. . Therefore, when the electric wire 16 is pulled from the connector 10, when the tensile force exceeds a first threshold value which is a reference value, the terminal 14 is normally inserted into the cavity 12, that is, passed. It can be determined that there is.

  However, if the electric wire 16 is pulled too strongly from the connector 10, the engaging structure between the engaging portion in the cavity 12 and the terminal 14 may be damaged, or the connection structure between the terminal 14 and the electric wire 16 may be damaged. . For this reason, when performing the said test, it is preferable to remove the thing from which the force pulling the electric wire 16 from the connector 10 becomes excessive as a product with possibility of breakage. Therefore, a second threshold value that is larger than the first threshold value and the tensile force of the electric wire 16 exceeds the second threshold value is determined to be unacceptable.

  As described above, when the tensile test is performed, the electric wire 16 or the connector 10 is pulled between the index finger 23 and the thumb. For this reason, the pulling force is distributed and received by the pulling force detector 40 on the index finger 23 side and the thumb. Therefore, the first threshold value and the second threshold value are determined in consideration of the force acting on the tensile force detection unit 40 in the tensile force in consideration of the force received by the opposite thumb. The first threshold value and the second threshold value are determined theoretically, experimentally, and empirically. The setting of the second threshold is not essential.

  The notification unit 60 is configured to notify the operator of the determination result in the determination unit 50. As a configuration for notification, notification by display, notification by sound, and the like are assumed. Here, the notification unit 60 includes two light emitting diodes 62 and 63.

  One output terminal of the determination result of the position of the determination unit 50 is connected to the anode of the light emitting diode 62 via the resistor R1, and the cathode of the light emitting diode 62 is grounded. The other output terminal of the determination result of the determination unit 50 is connected to the anode of the light emitting diode 63 via the resistor R2, and the cathode of the light emitting diode 63 is grounded. When the pulling force exceeds the first threshold value, the light emitting diode 62 is caused to emit light, and when the pulling force exceeds the second threshold value, the light emitting diode 63 is caused to emit light. Note that a common light emitting diode light emitting method (lighted display or blinking display) may be changed between when the pulling force exceeds the first threshold and when the pulling force exceeds the second threshold. The emission color may be changed.

  FIG. 4 is a flowchart showing processing in the determination unit 50.

  After the process starts, in step S1, the determination unit 50 determines whether or not the tensile force exceeds the first threshold based on the detection result of the tensile force detection unit 40. This step S1 is repeated until it is determined that the pulling force exceeds the first threshold value. If it is determined that the pulling force exceeds the first threshold value, the process proceeds to the next step S2. When the pulling force is the same as the first threshold value, the process of step S1 may be repeated or the process may proceed to the next step S2.

  In step S2, the determination unit 50 outputs a pass determination. Thereby, the light emitting diode 62 of the alerting | reporting part 60 light-emits. Thereby, the operator can recognize that the terminal 14 is normally inserted into the cavity 12 of the connector 10.

  In the next step S <b> 3, the determination unit 50 determines whether the tensile force exceeds the second threshold based on the detection result of the tensile force detection unit 40. This step S3 is repeated until it is determined that the tensile force exceeds the second threshold, and if it is determined that the tensile force exceeds the second threshold, the process proceeds to the next step S4. When the pulling force is the same as the second threshold value, the process of step S3 may be repeated or the process may proceed to the next step S4.

  In step S4, the determination unit 50 outputs a disqualification determination. Thereby, the light emitting diode 63 of the notification unit 60 emits light. Thereby, the operator can recognize that the electric wire 16 has been pulled too much.

  Thereafter, the process is terminated. Normally, the insertion operation and the test of the terminal 14 are continuously performed. Therefore, when a predetermined time (standard work time per terminal) elapses after the start of step S1, the process returns to step S1. Alternatively, a switch or the like may be provided in the mounting unit 30 and when the operator presses the switch, the process returns to step S1.

  5 and 6 are explanatory diagrams showing work procedures using the terminal insertion state inspection device 20. FIG.

  First, as shown in FIG. 5, the terminal 14 connected to the end of the electric wire 16 is inserted into the cavity 12 of the connector 10. At this time, the operator can perform the insertion operation of the terminal 14 by mounting the mounting portion 30 in one hand and grasping the electric wire 16 with the one hand. The mounting portion 30 itself has a glove shape, and the pulling force detection portion 40 is a sheet-like member attached to the finger cover portion 34, so that it does not easily interfere with the operation, and the insertion operation is easy. Can be done. The connector 10 may be held with the other hand.

  After inserting the terminal 14 into the cavity 12, the electric wire 16 is pulled. When the light emitting diode 62 emits light, it can be recognized that the terminal 14 can be normally inserted into the cavity 12. Thereafter, another terminal 14 is inserted as necessary.

  If the terminal 14 is removed from the cavity 12 before the light emitting diode 62 emits light, the terminal 14 is inserted into the cavity 12 again. Then, the electric wire 16 is pulled to check whether or not the light emitting diode 62 emits light, and whether or not the terminal 14 is normally inserted into the cavity 12 is checked.

  Further, when the light emitting diode 63 is turned on when the electric wire 16 is pulled, the operator can recognize that the electric wire 16 has been pulled with an excessive force. In this case, since there is a possibility that the locking portion in the cavity 12 and the locking portion between the terminal 14 and the like are damaged, the connector 10 is distinguished from others as a possible defect. Rework or discard as necessary.

  Thereby, a product in which the terminal 14 is normally inserted into each cavity 12 of the connector 10 can be manufactured.

  In the above example, the terminal insertion state inspection device 20 is attached to the hand having the electric wire 16, but the terminal insertion state inspection device 20 may be attached to the hand having the connector 10. Even in this case, if the electric wire 16 is pulled, a corresponding force acts on the connector 10 as well, so as in the above case, it is confirmed whether or not the pulling force of the electric wire 16 exceeds the first threshold value or the second threshold value. Therefore, it can be confirmed whether or not the terminal 14 has been normally inserted into the cavity 12.

  According to the terminal insertion state inspection apparatus 20 configured as described above, after inserting the terminal 14 into the cavity 12 of the connector 10, the electric wire 16 extending from the terminal 14 or the connector 10 is inserted into two sandwiched portions of the manpower 22. When it is sandwiched and pulled between the thumb and the index finger 23 (here, the physical force corresponding to the pulling force by the electric wire 16 or the connector 10 is detected by the pulling force detection unit 40, the detection result is output. Then, based on the detection result, a tensile test of the terminal 14 can be performed to determine whether the terminal 14 is normally inserted into the connector 10. At this time, the connector 10 or the electric wire 16 may be held by the other hand, or may be supported by another support member. For this reason, the tensile test of the terminal 14 can be performed even if the type of the connector 10 is different. Further, since the terminal insertion state inspection device 20 can be attached to the manpower 22, there are few restrictions on installation, and there are few restrictions on electrical wiring.

  Thereby, for example, when combining a plurality of sub-harnesses constituting a part of the wire harness, there is also an advantage that the test can be performed when the terminal 14 is inserted into the connector 10. That is, when the sub-harness is combined, it is difficult to inspect the terminal insertion state due to layout reasons on the assembly drawing board. In any case, inspection can be performed. As a result, it contributes to quality improvement of the wire harness.

  In addition, the operation of inserting the terminal 14 into the connector 10 can be performed manually, and the test can be efficiently performed by manually pulling the electric wire 16 or the like with the extension of the operation.

  Moreover, since the terminal insertion state inspection apparatus 20 is provided with the determination part 50 and the alerting | reporting part 60, it can recognize easily the pass / fail determination of the tension test of the terminal.

  Moreover, since the determination part 50 determines with a pass when a tensile force exceeds the 1st threshold value, and determines with a failure when a tensile force exceeds a 2nd threshold value, a tensile force is in a predetermined range, The case where 14 is normally inserted into the cavity 12 and an excessive tensile force does not act can be determined as acceptable.

  Moreover, since the mounting part 30 is glove-shaped, it is easy to perform various operations while the mounting part 30 is mounted on the hand 22. Further, the mounting portion 30 is difficult to be detached from the hand 22.

  Furthermore, since the tensile force detection unit 40 is a sheet-type shear force sensor, it is difficult to get in the way when performing various operations such as terminal insertion.

{Modifications}
Various modifications will be described based on the above embodiment.

  In the said embodiment, although the determination part 50 and the alerting | reporting part 60 were demonstrated in the example with which the mounting part 30 is mounted | worn, it is not necessarily required. For example, as shown in FIG. 7, a pass / fail determination device 150 may be provided separately from the mounting unit 30, and the determination unit 50 and the notification unit 60 may be provided in the pass / fail determination device 150. In this case, the detection result of the tensile force detection unit 40 is wirelessly communicated between the transmission circuit unit 142 connected to the tensile force detection unit 40 and the reception circuit unit 152 provided in the pass / fail determination device 150. Send it. Thereby, the operator can easily move his / her hand freely. But the tensile force detection part 40 and the pass / fail determination apparatus 150 may be connected via the electric wire etc.

  Moreover, in the said embodiment, although the mounting part 30 demonstrated in the example which is a glove shape, it does not necessarily need to be such a shape. For example, as shown in FIG. 8, the mounting portion 230 may be formed in a ring shape that can be fitted on the tip of the index finger 23, and the tensile force detection portion 40 may be attached to a part around the outer periphery thereof. . As a mounting part, what is necessary is just a structure which can be mounted | worn manually.

  Moreover, although the said embodiment demonstrated the example which supports the tension | tensile_strength detection part 40 in one of a thumb and a forefinger, you may provide a tension | tensile_strength detection part in both a thumb and a forefinger. In this case, for example, the above pass / fail determination may be performed based on the average value or the sum of the pulling forces based on the output results of the two pulling force detection units 40.

  Moreover, although the said embodiment demonstrated the example which supports the tension | pulling force detection part 40 on one side of a thumb and a forefinger on the assumption that the electric wire 16 or the connector 10 is pinched | interposed with a thumb and a forefinger, it is not necessarily required. For example, since the electric wire 16 and the connector 10 can be sandwiched and held between the index finger and the middle finger, the tensile force detection unit 40 may be supported on at least one of the index finger and the middle finger. Further, since the electric wire 16 and the connector 10 can be sandwiched and held between the thumb and the palm, the tensile force detection unit 40 may be supported on at least one of the thumb and the palm.

  Moreover, in the said embodiment, although the sheet-type shear force sensor was used as the tensile force detection part 40, it is not necessarily required, for example, the tensile force detection part 340 as shown in FIG. 9 may be used. The tensile force detection unit 340 includes a movable support unit 341, a movable unit 345, and a detection unit 349.

  The movable support portion 341 is fixed to the mounting portion 30. Here, as in the above-described embodiment, the tensile force detection unit 340 is fixed to the finger cover 34 of the mounting unit 30. More specifically, the movable support portion 341 includes a base portion 342 fixed to the finger cover portion 34 and a guide portion 343 extending from the distal end portion of the base portion 342 toward the proximal end side of the finger cover portion 34. Prepare. A stop portion 344 that protrudes toward the outer peripheral side (finger cover portion 34 side) of the guide portion 343 protrudes from the distal end portion of the guide portion 343.

  The movable part 345 is supported by the movable support part 341 so as to be movable. Here, the movable portion 345 is supported so as to be movable along the extending direction of the finger cover portion 34 (that is, the finger). More specifically, the movable part 345 is formed in a bowl shape in which a guide space 346 capable of accommodating the guide part 343 in a movable manner is formed. An opening 346h in which the base 342 can be disposed is formed on the finger cover 34 side of the movable part 345. Then, in a state where the guide part 343 is accommodated in the guide space 346, the base part 342 extends to the finger cover part 34 side through 346h. In a state where the base portion 342 is fixed to the finger cover portion 34, the movable portion 345 is supported to be movable at a position away from the finger cover portion 34. A portion of the movable portion 345 opposite to the finger cover portion 34 is formed in a planar shape that faces the same direction as the direction in which the belly of the finger in the finger cover portion 34 faces. This plane is disposed so as to be in contact with the electric wire or the connector.

  The detection unit 349 is configured to detect a physical quantity corresponding to the movement of the movable unit 345 relative to the movable support unit 341 and output the detection result. As the detection unit 349, various sensors using a general strain gauge or the like can be used. Here, the detection unit 349 is attached to a surface of the inner wall of the guide space 346 close to the base end portion of the finger cover portion 34. A portion of the detection unit 349 that receives a load faces the guide unit 343. When the movable portion 345 moves to the proximal end side of the finger cover portion 34, a portion of the movable portion 345 close to the finger cover portion 34 comes into contact with the detection portion 349. Thereby, the force received by the movable unit 345 is transmitted to the detection unit 349, and the force can be detected.

  A movable presser 350 is attached to the finger cover 33 on the thumb side. The movable presser part 350 has the same configuration as that in which the detection part 349 is omitted from the tensile force detection part 340.

  As shown in FIG. 10, according to the terminal insertion state inspection device 320 including the tensile force detection unit 340 and the movable presser unit 350, the movable unit 345 on the tensile force detection unit 340 side and the movable unit 345 on the movable presser unit 350 side are provided. The electric wire 16 can be pulled by sandwiching the electric wire 16 therebetween. Alternatively, as shown in FIG. 11, the other hand is supported with the connector 10 sandwiched between the movable portion 345 on the pulling force detection portion 340 side and the movable portion 345 on the movable presser portion 350 side and supported at a certain position. The electric wire 16 can be pulled.

  In any case, when the electric wire 16 or the like is pulled, the movable support portion 341 moves toward the base of the finger with respect to the movable portion 345 (the movable portion 345 moves toward the fingertip side with respect to the movable support portion 341). ), The movable support portion 341 contacts the detection portion 349. Then, the pulling force of the electric wire 16 against the connector 10 is detected by the detection unit 349. Based on the detection result, whether the terminal 14 is inserted or not can be determined as in the above embodiment.

  In the present modification, the movable pressing portion 350 on the thumb side may be omitted. If the movable presser part 350 is also provided on the thumb side, the pulling force acting on the electric wire 16 or the connector 10 acts more directly on the pulling force detection part 340, that is, the detection part 349. It can be performed. In order to allow the movable portion 345 of the movable presser portion 350 to move when the electric wire 16 or the like is pulled, it is preferable that the movable portion 345 is positioned on the base side of the finger in the initial state. For this purpose, the movable portion 345 may be moved to the base side by, for example, pointing the fingertip upward before performing the test.

  According to this modification, a general-purpose sensor or the like can be used as the detection unit.
