Description

[Technical Field]

[0001] The present disclosure relates to an inspection device, a determination device, a determination method, and a program. [Background technology]

[0002] It is known to use an inspection device to check the engagement state between the terminal fitting and the connector.

[0003] For example, Patent Document 1 discloses an inspection device that pushes in an electric wire terminal (hereinafter also referred to as a "terminal metal fitting") and checks the state of engagement with a connector. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-345158 Summary of the Invention [Problem to be solved by the invention]

[0005] Patent Document 1 discloses a connector terminal inspector that "when an electric wire terminal is normally present in a connector, the front probe abuts against the electric wire terminal in the connector during inspection and retracts against the biasing force to come into contact with the rear probe, and the output means of the inspection unit is electrically connected to the rear probe via the front probe. On the other hand, when an electric wire terminal is not normally present in the connector, the front probe abuts against the electric wire terminal in the connector during inspection and does not retract against the biasing force, does not come into contact with the rear probe, and the output means of the inspection unit is not electrically connected to the rear probe via the front probe. Therefore, by checking the electrical connection between the output means and the rear probe, it is possible to inspect whether an electric wire terminal is normally present in the connector. A connector terminal inspector that can easily inspect whether an electric wire terminal connected to an optional electric wire is correctly attached and accommodated." However, even if a terminal is present in the connector, there are times when the terminal is not fully engaged with the connector. In this case, when the terminal is pushed in with the front probe disclosed above, the terminal may come out of the connector with a force weaker than the force of the coil spring that biases the front probe. In this case, the front probe does not come into contact with the rear probe, making it difficult for the operator to distinguish between a state in which the terminal is not fully engaged with the connector and a state in which the terminal is not present in the connector.

[0006] In some cases, inspections are conducted only at the locations where terminals are present on the connector, based on the design data for the wiring harness. In such cases, if a terminal is present in a position where it should not be present in the design but is not fully engaged, the inspection may be deemed to have been successful due to the above-mentioned circumstances. If the terminals do not completely fall out of the connector and remain inside, the connector will pass inspection with a terminal arrangement that differs from the design data. This will result in the connector failing the continuity test in the next process, and it will take time to determine the cause of the failure and repair the connector. For these reasons, there is a demand for a method to detect when a terminal fitting is not properly engaged with the connector when inspecting an area other than where the terminal fitting is present within the connector.

[0007] An object of the present disclosure is to provide an inspection device, a determination device, a determination method, and a program that solve the above-mentioned problems. [Means for solving the problem]

[0014] Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings. Note that the drawings and specific configurations used in each embodiment should not be used to interpret the disclosure. The same or corresponding configurations in all drawings will be assigned the same reference numerals, and common descriptions will be omitted. It should be noted that in this disclosure, the drawings may relate to one or more embodiments.

[0015] First Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. An example of the configuration of an inspection device according to the present disclosure will be described below with reference to FIGS.

[0016] (Configuration of inspection equipment) The inspection device 1 is used to check the engagement state between the terminal fittings P and the connector C. The terminal fittings P include contact pins and sockets. As shown in FIG. 1, the inspection device 1 includes a first pressing member 10, a second pressing member 20, and a second conductive member 30. The second conductive member 30 faces a first conductive member 207 described below and has electrical conductivity. For example, the second conductive member 30 may have a cross-sectional shape that covers the compression coil spring 201 described later. For example, the second conductive member 30 may have a rectangular cross-section, and holes may be provided in the second conductive member 30. In this case, holes are provided individually so that the coupling portion 203L and the inspection probe 206 described later can be inserted therethrough.

[0017] As shown in FIGS. 2 and 3, the normal engagement state between the terminal fitting P and the connector C will be described. As shown in Fig. 2, a harness H is fixed to a terminal fitting P. The terminal fitting P can be locked in a connector C by a locking claw L. For example, the terminal fitting P may include the locking claw L, or the connector C may include the locking claw L (also called a "lance"). The connector C is provided with a through hole through which the terminal fitting P can be inserted. For ease of explanation, the connector C in this disclosure is assumed to have one through hole. As shown in Figures 2 and 3, the terminal fitting P is inserted into the through-hole from the direction D1. At this time, the locking claw L bends as it enters the connector C, and when the locking claw L is positioned in a recess provided in the connector C, the locking claw L returns to its original shape. In this way, the terminal fitting P is locked inside the through-hole.

[0018] (Configuration of the first pressing member) The first pressing member 10 includes a coupling portion 106 as shown in FIG. 4. An inspection probe 206 can be coupled to the coupling portion 106. During coupling, as shown in FIG. 5, an operator inserts the inspection probe 206 into the connector and then presses the terminal fitting P in a pressing direction D2. The pressing direction D2 is the direction in which the terminal fitting P comes out of the connector C. This makes it possible to check the engagement state between the terminal fitting P and the connector C. For example, the coupling portion 106 is a threaded portion. The threaded portion of the coupling portion 106 may be an internal thread or an external thread. In addition, when checking the locked state by using the first pressing member 10 alone with the inspection probe 206 engaged, only whether or not the terminal fitting P is present in the connector C is determined.

[0019] The first pressing member 10 includes an inner cylindrical portion 101, an outer cylindrical portion 102, a pusher 103, a switch 104, a first spring 105, and the aforementioned connecting portion 106. The outer cylinder 102 has a cylindrical recess at its top. A first spring 105 and a cylindrical inner cylinder 101 are arranged in this order in the recess. The first spring 105 is a compression coil spring. The first spring 105 applies a predetermined force to the terminal fitting P by biasing the inspection probe 206. The first spring 105 bends by an amount related to the biasing force applied to the inspection probe 206. A pusher 103 is disposed on the outer circumferential surface of the inner cylindrical portion 101 . A switch 104 is disposed on the end face of the outer cylindrical portion 102. The switch 104 comes into contact with the pusher 103. As shown in FIGS. 4 and 5, an extension member may be provided on the outer cylindrical portion 102 by extending a part of the outer cylindrical portion 102 in the radial direction, and the switch 104 may be disposed on the extension member.

[0020] Here, the operation when the inspection probe 206 is coupled to the coupling portion 106 will be described. As shown in FIG. 5, the worker inserts the inspection probe 206 of the first pressing member 10 into the connector, and then presses the terminal fitting P in the pressing direction D2. Thereafter, by pressing the inner cylindrical portion 101 in the pressing direction D2, the first spring 105 is compressed, and the inner cylindrical portion 101 slides within the outer cylindrical portion 102. As the first spring 105 contracts, the pusher 103 becomes able to press the switch 104. As shown in FIG. 6, when the pusher 103 presses the switch 104, a predetermined force is applied to the terminal fitting P. If the terminal fitting P does not fall out of the connector C at this time, the worker can determine that the terminal fitting P is properly locked in the connector C.

[0021] The first pressing member 10 may include the first spring 105, which is a compression coil spring, and may be configured to press the terminal fitting P in the pressing direction D2. Therefore, the first pressing member 10 is not limited to the configuration disclosed herein.

[0022] Furthermore, when the connecting portion 203L of the second pressing member 20 and the first pressing member 10 are connected in the pressing direction D2, the first spring 105 has the following spring constant: The spring constant of the first spring 105 is larger than the spring constant of a compression coil spring 201, which will be described later.

[0023] (Configuration of the second pressing member) The second pressing member 20 and the second conductive member 30 have the role of improving the function of the first pressing member 10. Therefore, the second pressing member 20 is coupled to the first pressing member 10 in a pressing direction D3 along the direction of gravity, and is capable of pressing the terminal fitting P. The second pressing member 20 can be used alone with the second conductive member 30 .

[0024] As shown in FIG. 7, the second pressing member 20 includes a compression coil spring 201, a pressing portion 203, a base portion 204, a stopper 205, the above-mentioned inspection probe 206, contact sensors A, B, and X, and a first conductive member 207.

[0025] The second pressing member 20 may also include an reducing diameter spring 202, which is a compression coil spring of a different diameter, coaxially with the compression coil spring 201. In this case, the pressing portion 203 has a first contact portion that can come into contact with the compression coil spring 201 and a second contact portion that can come into contact with the reducing diameter spring. In the pressing direction, the position of the first contact portion and the position of the second contact portion are different. As a result, the spring characteristic of the second pressing member 20 in the pressing direction D3 is nonlinear.

[0026] For example, the compression coil spring 201 and the reducing spring 202 have linear characteristics. However, when the second pressing member 20 is provided with only the compression coil spring 201 and it is desired that the spring characteristic of the second pressing member 20 in the pressing direction D3 be a nonlinear characteristic, the compression coil spring 201 may be a compression coil spring having the following nonlinear characteristics. Examples include a conical coil spring, a drum-shaped coil spring, a barrel-shaped coil spring, and a square-shaped coil spring.

[0027] The pushing portion 203 can push the compression coil spring 201 in a pushing direction D3 that is aligned with the direction of gravity. The pushing portion 203 narrows as it approaches the pushing direction D3. For example, the pushing portion 203 may have a stepped shape. In the present disclosure, the pushing portion 203 has a plurality of cylindrical steps.

[0028] As described above, in the second pressing member 20 of the present disclosure, the position of the first contact portion and the position of the second contact portion differ in the pressing direction. For example, in the present disclosure, the pushing portion 203 has a plurality of cylindrical steps. The height dimension of each step of the pushing portion 203 in the pressing direction D3 is determined by the contact between the pushing portion 203 and the compression coil spring 201 (reduced diameter spring 202). In the present disclosure, the height dimension of the step is determined so that the pushing portion 203 contacts the compression coil spring 201 before the reduced diameter spring 202.

[0029] A coupling portion 203L is provided in a part of the pushing portion 203. The coupling portion 203L can be coupled to the coupling portion 106 of the first pressing member 10. The coupling portion 203L may be a male screw or a female screw. In addition, since the second pressing member 20 can be used alone, the connecting portion 203L may be connected to a member for holding, or the connecting portion 203L may be connected to a part of the actuator.

[0030] The inspection probe 206 is capable of pressing the terminal fitting P inserted into the connector C. Via the base portion 204 , the test probe 206 moves together with the compression coil spring 201 .

[0031] Contact sensors A, B, and X detect contact between the pushing portion 203 and the compression coil spring 201. Contact sensors A, B, and X may be embedded in push-in portion 203. For example, contact sensor A is provided on surface S1, which is the surface located at the tip of push-in portion 203. Contact sensor B is provided on surface S2, which is the step above that, and contact sensor X is provided on surface S3, which is the step above that.

[0032] Compression coil spring 201, reducing spring 202, and stopper 205 are provided on one surface of base portion 204. Inspection probe 206 is coupled to the other surface of base portion 204. For example, base portion 204 and inspection probe 206 may be integrally formed. The base portion 204 is a plate-like member. For example, as shown in Figures 8 and 9, the base portion 204 is a circular plate.

[0033] The stopper 205 is capable of coming into contact with the pushing portion 203 . For example, the stopper 205 is a cylindrical member as shown in Figures 8 and 9. In this case, the stopper 205 is installed on the base portion 204 coaxially with the second spring. The stopper 205 of the present disclosure is located outside the compression coil spring 201, but may be located inside the compression coil spring 201.

[0034] As described above, the inspection probe 206 is capable of contacting the terminal fitting P.

[0035] The first conductive member 207 is conductive. As shown in Figures 8 and 9, a hole is provided in the center of the first conductive member 207, and the inspection probe 206 is inserted through the hole. For example, the first conductive member 207 is made of conductive rubber.

[0036] In the present disclosure, the following matters regarding the spring constant are taken into consideration depending on the shape of the pushing portion 203 and the arrangement and spring constant of the reducing diameter spring 202.

[0037] (1) The pushing portion 203 narrows in the pushing direction D3. (2) The reducing spring 202 is located between the stopper 205 and the compression coil spring 201. (3) The inner diameter of the reducing spring 202 is larger than the inner diameter of the compression coil spring 201. When these three conditions are met, the spring constant of the reducing spring 202 is greater than the spring constant of the compression coil spring 201 and is smaller than the spring constant of the first spring 105.

[0038] (operation) The inspection device 1 is capable of the following operations: The base portion 204 to which the inspection probe 206 is coupled is slidable in the pressing direction D3 via the compression coil spring 201.

[0039] When the terminal fitting P falls off the connector C, the inspection probe 206 moves while maintaining contact between the pushing portion 203 and the compression coil spring 201. This establishes electrical continuity between the first conductive member 207 and the second conductive member 30. At this time, at least the contact sensor A detects the contact.

[0040] When there is no terminal fitting P inserted into the connector C, the first conductive member 207 and the second conductive member 30 are electrically connected without contact between the pushing portion 203 and the compression coil spring 201. For example, when there is no terminal fitting P inserted into the connector C, the inspection probe 206 moves away from the pushing portion 203 due to gravity. This brings the first conductive member 207 and the second conductive member 30 into electrical continuity. At this time, there is no contact between the pushing portion 203 and the compression coil spring 201.

[0041] (Judgment method) A determination method using the inspection device 1 according to the present disclosure will be described with reference to FIG. The determination method using the inspection device 1 according to the present disclosure is carried out according to the flow shown in Fig. 10. As an example of the terminal fitting P, a contact pin will be described.

[0042] Although the inspection device 1 of the present disclosure may be operated by an actuator or the like, for ease of explanation, it will be treated as being operated by an operator.

[0043] The operation of the inspection device 1 starts when the inspection probe 206 is inserted into the connector C. With reference to design data relating to the wiring of the harness H, an inspection is carried out for the locations where the contact pins are present in the connector C.

[0044] From the state shown in FIG. 11, the worker inserts the inspection probe 206 into the connector C (ST11).

[0045] After performing ST11, the worker can determine whether or not the contact pin is present in the connector C based on the contact state of the first conductive member 207. If the first conductive member 207 is not in contact with the second conductive member 30 (ST12: NO), the tip of the inspection probe 206 will come into contact with the contact pin and stop. 12, if the first conductive member 207 is in contact with the second conductive member 30 (ST12: YES), it is determined that the contact pin is not inserted (ST13), and the contact pin inspection fails (ST28). In other words, the worker can determine that the contact pin is not present in the connector C.

[0046] When there is no contact pin inserted into the connector C, the inspection probe 206 moves away from the push-in portion 203 due to gravity, thereby establishing electrical continuity between the first conductive member 207 and the second conductive member 30. At this time, there is no contact between the push-in portion 203 and the compression coil spring 201. At this time, the contact sensor A does not detect contact between the pushing portion 203 and the compression coil spring 201. The worker can also determine whether or not contact has been detected, thereby obtaining confirmation that the contact pin has not been inserted (ST13).

[0047] If the answer is NO (ST12), proceed to the next step. 13, the operator presses the inspection probe 206 in a pressing direction D3 using the first pressing member 10 (pressing portion 203) to bring the surface S1 into contact with the compression coil spring 201. At this time, the contact sensor A detects contact between the pressing portion 203 and the compression coil spring 201 (ST14).

[0048] After performing ST14, the operator presses the inspection probe 206 in the pressing direction D3 using the first pressing member 10 (the pressing portion 203), which causes the compression coil spring 201 to contract and applies a bias to the contact pin (ST15). Since the spring constant of the compression coil spring 201 is smaller than that of the first spring 105, the compression coil spring 201 compresses more than the first spring 105. At this time, since it is mainly the compression coil spring 201 that applies a force to the contact pin, the force applied increases linearly.

[0049] After performing ST14, the worker can determine whether or not the contact pin is properly locked in the connector C based on the contact state of the first conductive member 207. If the first conductive member 207 is not in contact with the second conductive member 30 (ST16: NO), this means that the contact pin is kept locked. If the first conductive member 207 is in contact with the second conductive member 30 (ST16: YES), the contact pin is deemed to be insufficiently locked (ST17), and the contact pin inspection is rejected (ST28). In other words, the operator can determine that the contact pin is present in the connector C but is not locked properly.

[0050] When the contact pin falls off the connector C, the inspection probe 206 moves while maintaining contact between the pushing portion 203 and the compression coil spring 201. This establishes electrical continuity between the first conductive member 207 and the second conductive member 30. At this time, the contact is detected by the contact sensor A. The worker can also determine whether or not contact has been detected by contact sensor A, thereby obtaining confirmation that the contact pins are not sufficiently locked (ST17).

[0051] Following the execution of ST16, the worker presses the inspection probe 206 in the pressing direction D3 using the first pressing member 10 (pressing portion 203). This causes the compression coil spring 201 to contract, and the surface S2 comes into contact with the reducing diameter spring 202. At this time, the worker can determine whether or not the contact sensor B has detected contact between the pressing portion 203 and the reducing diameter spring 202. If the contact is not detected by the contact sensor B (ST18: NO), the worker continues to press the inspection probe 206 in the pressing direction D3 using the first pressing member 10 (pressing portion 203).

[0052] 14, the surface S2 comes into contact with the reducing diameter spring 202. At this time, the contact sensor B detects the contact between the pushing portion 203 and the reducing diameter spring 202.

[0053] Following the execution of ST18, the operator further presses the inspection probe 206 in the pressing direction D3 using the first pressing member 10 (the pressing portion 203). This causes the compression coil spring 201 and the reducing diameter spring 202 to contract, and a greater biasing force is applied to the contact pin (ST19). If the spring constant of the reduced diameter spring 202 is smaller than that of the first spring 105, the reduced diameter spring 202 will compress more than the first spring 105. At this time, the biasing force applied to the contact pin is mainly provided by the compression coil spring 201 and the reduced diameter spring 202, and therefore the biasing force increases exponentially.

[0054] After performing ST19, the worker can determine whether or not the contact pin is properly locked in the connector C based on the contact state of the first conductive member 207. If the first conductive member 207 is not in contact with the second conductive member 30 (ST20: NO), this means that the contact pin is kept locked. If the first conductive member 207 is in contact with the second conductive member 30 (ST20: YES), the contact pin is deemed to be insufficiently locked (ST21), and the contact pin inspection fails (ST28). In other words, the worker can determine that the contact pin is present in the connector C but is not locked sufficiently.

[0055] When the contact pin falls off the connector C, the inspection probe 206 moves while maintaining contact between the pushing portion 203 and the compression coil spring 201. This state is shown in FIG. 15. As a result, the first conductive member 207 and the second conductive member 30 are electrically connected. At this time, the contact is detected by the contact sensor B. The worker can also determine whether or not contact has been detected by contact sensor B, thereby obtaining confirmation that the contact pins are not sufficiently locked (ST21).

[0056] Following the execution of ST20, the worker presses the inspection probe 206 in the pressing direction D3 using the first pressing member 10 (pressing portion 203). This causes the compression coil spring 201 to contract, and the surface S3 comes into contact with the stopper 205. At this time, the worker can determine whether or not the contact sensor X has detected contact between the pressing portion 203 and the stopper 205. If the contact sensor X does not detect contact (ST22: NO), the worker continues to press the inspection probe 206 in the pressing direction D3 using the first pressing member 10 (pressing portion 203).

[0057] 16, when contact is detected by the contact sensor X (ST22: YES), the surface S3 comes into contact with the stopper 205. At this time, the contact sensor X detects contact between the push-in portion 203 and the stopper 205.

[0058] After performing ST22, the operator further presses the inspection probe 206 in the pressing direction D3 using the first pressing member 10. This causes the first spring 105 to contract, and a larger bias is applied to the contact pin (ST23). At this time, the biasing force to the contact pin is mainly provided by the compression coil spring 201, the reducing spring 202, and the first spring 105.

[0059] After performing ST23, the worker can determine whether or not the contact pin is properly locked in the connector C based on the contact state of the first conductive member 207. If the first conductive member 207 is not in contact with the second conductive member 30 (ST24: NO), this means that the contact pin is kept locked. If the first conductive member 207 is in contact with the second conductive member 30 (ST24: YES), the contact pin is deemed to be insufficiently locked (ST25), and the contact pin inspection fails (ST28). In other words, the worker can determine that the contact pin is present in the connector C but is not locked sufficiently.

[0060] When the contact pin falls off the connector C, the inspection probe 206 moves while maintaining contact between the pushing portion 203 and the compression coil spring 201. This brings the first conductive member 207 and the second conductive member 30 into electrical conduction. At this time, the contact is detected by the contact sensor X. The worker can also determine whether or not contact has been detected by the contact sensor X to be sure that the contact pins are not sufficiently locked (ST25).

[0061] Following the execution of ST24, the worker pushes the inspection probe 206 in the pushing direction D3 using the first pushing member 10. This causes the first spring 105 to contract, enabling the pusher 103 to press the switch 104. At this time, the worker can determine whether the pusher 103 has pressed the switch 104. If the switch 104 has not been pressed (ST26: NO), the worker continues to push the inspection probe 206 in the pushing direction D3 using the first pushing member 10.

[0062] As shown in FIG. 17, if the pusher 103 presses the switch 104 (ST26: YES), the contact pin passes the inspection as the desired force is applied to the contact pin by the biasing force of the first spring 105 (ST27).

[0063] (Action and effect) According to the inspection device 1 of the present disclosure, the pushing portion 203 can push the compression coil spring 201 in the pushing direction D3. The inspection probe 206 moves together with the compression coil spring 201, thereby making it possible to push the terminal fitting P inserted into the connector C. By including a contact sensor A that detects contact between the pushing portion 203 and the compression coil spring 201, it can be estimated from the detection of contact that the inspection probe 206 is pushing the terminal fitting P. By including the first conductive member 207 and the second conductive member 30, it becomes easier to determine whether the inspection probe 206 is pressing against the terminal fitting P. For example, by moving the inspection probe 206 while maintaining contact detection by the contact sensor A, the first conductive member 207 and the second conductive member 30 become conductive. This allows an operator or a computer to determine whether the terminal fitting P has fallen out of the connector C. In other words, it can be determined that the terminal fitting P is not sufficiently locked in the connector C. For example, when the inspection probe 206 moves away from the push-in portion 203 due to gravity, the first conductive member 207 and the second conductive member 30 become conductive. This allows an operator or a computer to determine that the terminal fitting P is not present in the connector C. As described above, the inspection device of the present disclosure can distinguish between a state in which the terminal fitting P is not present in the connector C and a state in which the terminal fitting P is not sufficiently locked to the connector C. Therefore, when inspecting areas other than those where terminal fittings are present within the connector, the inspection device of the present disclosure is likely to detect that the terminal fittings and the connector are present within the connector in an insufficient state of engagement.

[0064] Furthermore, the inspection device of the present disclosure "includes a compression coil spring 201, a pushing portion 203 capable of pushing the compression coil spring 201 in a pushing direction, an inspection probe 206 that moves together with the compression coil spring 201 and is capable of pushing a terminal fitting P inserted into a connector C, a contact sensor A that detects contact between the pushing portion 203 and the compression coil spring 201, a first conductive member 207 that is conductive and through which the inspection probe 206 is inserted, and a second conductive member 30 that is conductive and faces the first conductive member 207, and when the terminal fitting P falls off, the first conductive member 207 and the second conductive member 30 are electrically connected while maintaining contact, and when the terminal fitting P is absent, the first conductive member 207 and the second conductive member 30 are electrically connected without contact," thereby achieving the following effects. In the inspection device of the present disclosure, the pushing portion 203 can push the compression coil spring 201 in a pushing direction D3 along the direction of gravity. The inspection probe 206 moves together with the compression coil spring 201, thereby pushing the terminal fitting P inserted into the connector C. By including a contact sensor A that detects contact between the pushing portion 203 and the compression coil spring 201, it can be inferred from the detection of contact that the inspection probe 206 is pushing the terminal fitting P. By including the first conductive member 207 and the second conductive member 30, it becomes easier to determine whether the inspection probe 206 is pressing against the terminal fitting P. For example, by moving the inspection probe 206 while maintaining contact detection by the contact sensor A, the first conductive member 207 and the second conductive member 30 become conductive. This allows an operator or a computer to determine whether the terminal fitting P has fallen out of the connector C. In other words, it can be determined that the terminal fitting P is not sufficiently locked in the connector C. For example, when the inspection probe 206 moves away from the push-in portion 203 due to gravity, the first conductive member 207 and the second conductive member 30 become conductive. This allows an operator or a computer to determine that the terminal fitting P is not present in the connector C. From the above, it is possible to obtain the effect that "the inspection device of the present disclosure can distinguish between a state in which the terminal fitting P is not sufficiently engaged with the connector C and a state in which the terminal fitting P is not present in the connector C." Therefore, when inspecting a portion of the connector other than where the terminal fitting is present, the inspection device according to the present disclosure can easily detect when the terminal fitting is not sufficiently engaged with the connector.

[0065] In addition, the inspection device of the present disclosure further includes "a first pressing member 10 capable of pressing the terminal fitting P in the pressing direction, and a stopper 205 capable of contacting the pressing portion 203, the pressing portion 203 being coupled to the first pressing member 10, and the first pressing member 10 including a first spring 105 having a spring constant greater than that of the compression coil spring 201," thereby achieving the following effects. With the above configuration, the spring constant of the compression coil spring 201 included in the second pressing member 20 is smaller than the spring constant of the first spring 105. Therefore, the spring constant of the compression coil spring 201 can be set to be weaker than the force required to remove the terminal fitting P. At this time, in the pressing direction, the displacement associated with the compression coil spring 201 is greater than the displacement associated with the first spring 105. Since the stroke amount of the pushing portion 203 is greater than the stroke amount of the first pressing member 10 after the pushing portion 203 and the compression coil spring 201 come into contact until the stopper 205 restricts the movement, it is easy to determine whether the terminal fitting has fallen off. From the above, the effect that "the inspection device of the present disclosure achieves improved functionality by the second pressing member 20 and the second conductive member 30 while still utilizing the functions of the first pressing member 10" can be obtained.

[0066] Furthermore, the inspection device of the present disclosure further includes "an unequal diameter spring 202, which is a compression coil spring of a different diameter, arranged coaxially with the compression coil spring 201, and an unequal diameter spring contact sensor (contact sensor B) that detects contact between the pushing portion 203 and the unequal diameter spring 202, and has a first contact portion that can come into contact with the compression coil spring and a second contact portion that can come into contact with the unequal diameter spring, and the position of the first contact portion and the position of the second contact portion are different in the pressing direction," thereby achieving the following effects. With the above configuration, the spring characteristic of the second pressing member 20 in the pressing direction D3 is nonlinear. As a result, it is possible to obtain the effect that "a greater biasing force can be applied to the terminal fitting P." In addition, by observing the detection of contact by the contact sensor A and the contact sensor for the reducing diameter spring (contact sensor B), it is possible to estimate the magnitude of the biasing force applied to the terminal fitting P.

[0067] Furthermore, in the inspection device of the present disclosure, the following effect can be obtained by "the pushing portion 203 narrowing toward the pushing direction D3, the uneven diameter spring 202 being positioned between the stopper 205 and the compression coil spring 201, the inner diameter of the uneven diameter spring 202 being larger than the inner diameter of the compression coil spring 201, and the spring constant of the uneven diameter spring 202 being larger than the spring constant of the compression coil spring 201 and smaller than the spring constant of the first spring 105." With the above configuration, the pushing portion 203 narrows as it moves in the pressing direction D3. After the narrowed tip portion comes into contact with the reducing diameter spring 202, the pushing portion 203 is pushed in, causing the reducing diameter spring 202 to contract. When the tip portion comes into contact with the reducing diameter spring 202, the narrowed shape of the pushing portion acts as a guide. As a result, the effect of "suppressing displacement of the reducing diameter spring 202 due to contact between the pushing portion 203 and the reducing diameter spring 202" can be obtained.

[0068] Furthermore, in the inspection device of the present disclosure, the following effect can be obtained by "the pressing portion having a stepped shape." With the above configuration, the pushing portion 203 narrows as it moves in the pressing direction D3. After the narrowed tip portion comes into contact with the reducing diameter spring 202, the pushing portion 203 is pushed in, causing the reducing diameter spring 202 to contract. When the tip portion comes into contact with the reducing diameter spring 202, the narrowed shape (stepped shape) of the pushing portion acts as a guide. As a result, the effect of "suppressing displacement of the reducing diameter spring 202 due to contact between the pushing portion 203 and the reducing diameter spring 202" can be obtained.

[0069] Furthermore, in the inspection device of the present disclosure, the second conductive member 30 has a cross-sectional shape that covers the compression coil spring 201, which provides the effect of protecting the operator and preventing loss of the compression coil spring 201 due to the spring characteristic of the compression coil spring 201. This is significant when the spring characteristic of the compression coil spring 201 is nonlinear, because the reaction force of the compression coil spring 201 is greater than that of a spring with linear characteristics.

[0070] Furthermore, in the inspection device of the present disclosure, the effect that "the spring characteristics of the compression coil spring 201 have nonlinear characteristics" can be obtained, and therefore "greater biasing force can be applied to the terminal fitting P."

[0071] (Variation) For example, like the second pressing member 20, the first pressing member 10 may also include a stopper in the outer cylinder 102 that adjusts the amount of deflection of the first spring 105. In this case, instead of the pusher 103 pressing down the switch 104, the first pressing member 10 may pass the inspection of the terminal fitting P on the grounds that the amount of deflection of the first spring 105 is limited by the stopper.

[0072] For example, the pushing portion 203 may have a triangular cross-sectional shape that narrows in the pushing direction D3.

[0073] Second Embodiment An example of the configuration of an inspection device according to the present disclosure will be described below with reference to FIGS. In addition, components common to those disclosed above are given the same reference numerals and detailed description thereof will be omitted.

[0074] (Configuration of inspection equipment) As shown in FIG. 18, the inspection device 1B is similar to that disclosed above, except as described below. The inspection device 1B includes a first pressing member 10, a second pressing member 20B, and a second conductive member 30.

[0075] (Configuration of the second pressing member) As shown in FIG. 19, the second pressing member 20B includes a compression coil spring 201B, a reducing diameter spring 202B, a pushing portion 203B, a base portion 204, a stopper 205B, the above-mentioned inspection probe 206, contact sensors D, E, and F, and a first conductive member 207.

[0076] In the following disclosure, the positional relationship and the magnitude relationship of the spring constants of the compression coil spring 201B and the reducing diameter spring 202B are different. In the following disclosure, it is assumed that the pushing portion 203B has a plurality of cylindrical steps. In the following disclosure, the stopper 205B is located inside the compression coil spring 201B.

[0077] In the second pressing member 20B of the present disclosure, the positions of the first contact portion and the second contact portion are different in the pressing direction. For example, in the following disclosure, the pressing portion 203 is a plate-shaped member. The reducing diameter spring 202B and the compression coil spring 201B are connected by a connecting member, and the compression coil spring 201B and the stopper 205B are connected by a connecting member. The connection by the connecting member is shown in FIG. 20. In the following disclosure, the pushing portion 203B is arranged so as to come into contact with the reducing diameter spring 202 before the compression coil spring 201B.

[0078] In the following disclosure, the following matters regarding the spring constant are taken into consideration depending on the shape of the pushing portion 203B and the arrangement and spring constant of the reducing diameter spring 202B.

[0079] (4) The pushing portion 203B is a plate-like member. (5) Compression coil spring 201B is located between stopper 205B and reducing diameter spring 202B. As shown in Fig. 21, reducing diameter spring 202B is located outside compression coil spring 201B. (6) The inner diameter of the reducing spring 202B is larger than the inner diameter of the compression coil spring 201B. When these three conditions are met, the spring constant of the reducing spring 202B is smaller than the spring constant of the compression coil spring 201B and is smaller than the spring constant of the first spring 105.

[0080] Contact sensors D, E, and F are arranged as follows: For example, on surface S1 of push-in portion 203B, contact sensor D is provided at the point of contact with reducing diameter spring 202B, contact sensor E is provided at the point of contact with compression coil spring 201B, and contact sensor F is provided at the point of contact with stopper 205B.

[0081] (Judgment method) The operation of the inspection device 1B is the same as that shown in the flowchart of Fig. 10, except for the points described below. When the pusher 103 presses the switch 104 in the inspection device 1B, the state shown in Fig. 18 is reached. In the inspection device 1B, the push-in portion 203B is positioned so that it comes into contact with the reducing diameter spring 202 before the compression coil spring 201B. Therefore, contact sensor D first detects contact between the push-in portion 203B and the reducing diameter spring 202B. Then, contact sensor E detects contact between the push-in portion 203B and the compression coil spring 201B. Finally, contact sensor F detects contact between the push-in portion 203B and the stopper 205B.

[0082] (Action and effect) According to the inspection device 1B of the present disclosure, the pushing portion 203B can push the compression coil spring 201B in the pushing direction D3. The inspection probe 206 moves together with the compression coil spring 201B, thereby pushing the terminal fitting P inserted into the connector C. By including a contact sensor E that detects contact between the pushing portion 203B and the compression coil spring 201B, it can be inferred from the detection of contact that the inspection probe 206 is pushing the terminal fitting P. By including the first conductive member 207 and the second conductive member 30, it becomes easier to determine whether the inspection probe 206 is pressing against the terminal fitting P. For example, by moving the inspection probe 206 while maintaining contact detection by the contact sensor E, the first conductive member 207 and the second conductive member 30 become conductive. This allows an operator or a computer to determine whether the terminal fitting P has fallen out of the connector C. In other words, it can be determined that the terminal fitting P is not sufficiently locked in the connector C. For example, when the inspection probe 206 moves away from the push-in portion 203B due to gravity, the first conductive member 207 and the second conductive member 30 become conductive. This allows an operator or a computer to determine that the terminal fitting P is not present in the connector C. As described above, the inspection device of the present disclosure can distinguish between a state in which the terminal fitting P is not present in the connector C and a state in which the terminal fitting P is not sufficiently locked to the connector C. Therefore, when inspecting areas other than those where terminal fittings are present within the connector, the inspection device of the present disclosure is likely to detect that the terminal fittings and the connector are present within the connector in an insufficient state of engagement.

[0083] Furthermore, in the inspection device 1B of the present disclosure, the following effects can be obtained by "the pushing portion being a plate-shaped member, the compression coil spring being located between the stopper and the unequal diameter spring, the inner diameter of the unequal diameter spring being larger than the inner diameter of the compression coil spring, and the spring constant of the unequal diameter spring being smaller than the spring constant of the compression coil spring." With the above configuration, the reducing diameter spring 202B has a smaller spring constant than the compression coil spring 201B, and therefore compresses more than the compression coil spring 201B. The reducing diameter spring 202B, which has a larger inner diameter than the compression coil spring 201B, is compressed more by the pushing portion 203B, and the momentum of the reducing diameter spring 202B when it comes into contact with the compression coil spring 201B is neutralized. Therefore, it is possible to obtain the effect that "it is easy to suppress displacement of the compression coil spring 201B due to contact."

[0084] Third Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. An example of the configuration of an inspection device according to the present disclosure will be described below with reference to FIG.

[0085] (composition) The inspection device 1m includes a compression coil spring 201m, a pushing portion 203m capable of pushing the compression coil spring 201m in a pushing direction, an inspection probe 206m that moves together with the compression coil spring 201m and is capable of pushing a terminal fitting inserted into a connector, a contact sensor S that detects contact between the pushing portion 203m and the compression coil spring 201m, a first conductive member 207m that is conductive and through which the inspection probe 206m is inserted, and a second conductive member 30m that is conductive and faces the first conductive member, and when the terminal fitting P is absent, the first conductive member 207m and the second conductive member 30m are conductive without contact.

[0086] (Action and effect) According to the inspection device 1m of the present disclosure, the pushing portion 203m can push the compression coil spring 201m in the pushing direction. The inspection probe 206m moves together with the compression coil spring 201m, thereby pressing the terminal fitting inserted into the connector. By including a contact sensor S that detects contact between the pushing portion 203m and the compression coil spring 201m, it can be estimated from the detection of contact that the inspection probe 206m is pressing the terminal fitting. The inclusion of the first conductive member 207m and the second conductive member 30m, which are conductive, makes it easier to determine whether the inspection probe 206m is pressing against the terminal metal fitting. For example, by moving the inspection probe 206m while maintaining contact detection by the contact sensor S, the first conductive member 207m and the second conductive member 30m become conductive. This allows an operator or a computer to determine whether the terminal fitting has fallen out of the connector, i.e., whether the terminal fitting is not properly locked in the connector. For example, gravity causes the inspection probe 206m to move away from the push-in portion 203m, thereby establishing electrical continuity between the first conductive member 207m and the second conductive member 30m, allowing an operator or computer to determine that there is no terminal metal fitting in the connector. As described above, the inspection device of the present disclosure can distinguish between a state in which the terminal fitting and the connector are insufficiently engaged and a state in which the terminal fitting is not present in the connector. Therefore, when inspecting areas other than those where terminal fittings are present within the connector, the inspection device of the present disclosure is likely to detect that the terminal fittings and the connector are present within the connector in an insufficient state of engagement.

[0087] <Fourth embodiment> An example of the determination method according to the present disclosure will be described below with reference to FIG. The determination method in the present disclosure is carried out according to the flow shown in FIG.

[0088] The determination method is performed using an inspection device that includes a compression coil spring, a pushing portion that can push the compression coil spring in a pushing direction, an inspection probe that moves together with the compression coil spring and can push a terminal fitting inserted into a connector, a contact sensor that detects contact between the pushing portion and the compression coil spring, a first conductive member that is conductive and through which the inspection probe is inserted, and a second conductive member that is conductive and faces the first conductive member. The determination method includes a step (ST100) of determining whether or not contact has been detected, and a step (ST200) of determining whether or not conduction has occurred between the first conductive member and the second conductive member.

[0089] (Action and effect) According to the determination method of the present disclosure, an inspection device is used that includes a compression coil spring, a pushing portion capable of pushing the compression coil spring in a pushing direction, an inspection probe that moves together with the compression coil spring and is capable of pushing a terminal fitting inserted into a connector, a contact sensor that detects contact between the pushing portion and the compression coil spring, a first conductive member that is conductive and through which the inspection probe is inserted, and a second conductive member that is conductive and faces the first conductive member. For example, the first conductive member and the second conductive member are electrically connected by moving the inspection probe while the contact sensor continues to detect contact. By determining whether contact is detected and whether electrical continuity exists between the first conductive member and the second conductive member, an operator or a computer can determine whether the terminal fitting has fallen out of the connector, i.e., whether the terminal fitting is not sufficiently locked in the connector. For example, gravity causes the inspection probe to move away from the push-in portion, thereby establishing electrical continuity between the first and second conductive members. By determining whether contact has been detected and whether electrical continuity has been established between the first and second conductive members, an operator or a computer can determine that no terminal fitting is present in the connector. As described above, the determination method of the present disclosure can distinguish between a state in which the terminal fitting is not sufficiently engaged with the connector and a state in which the terminal fitting is not present in the connector. Therefore, the determination method of the present disclosure makes it easy to detect when a terminal fitting is present in a connector in an insufficient state of engagement with the connector when inspecting an area other than where the terminal fitting is present in the connector.

[0090] Although the present disclosure has been described above with reference to the embodiments, the present disclosure is not limited to the above-described embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure. Furthermore, each embodiment can be combined with other embodiments as appropriate.

[0091] <Other variations> The above-described determination method may be performed by a determination device. As shown in FIG. 24, the determination device 40 includes a contact determination unit 410 and a continuity determination unit 420. The determination device 40 uses an inspection device that includes a compression coil spring, a pushing portion that can push the compression coil spring in a pushing direction, an inspection probe that moves together with the compression coil spring and can push a terminal fitting inserted into a connector, a contact sensor that detects contact between the pushing portion and the compression coil spring, a first conductive member that is conductive and through which the inspection probe is inserted, and a second conductive member that is conductive and faces the first conductive member.

[0092] The contact determination unit 410 determines whether or not contact between the pressing portion and the compression coil spring has been detected. For example, the contact determination unit 410 receives an electrical signal from the contact sensor A and determines whether or not contact has been detected (ST100). The conduction determination unit 420 determines whether or not there is conduction between the first conductive member and the second conductive member. For example, the conduction determination unit 420 receives an electric signal that flows when there is conduction between the first conductive member and the second conductive member, and determines whether or not there is conduction (ST200).

[0093] 25 is a hardware configuration diagram showing the configuration of a computer 1100 according to the present disclosure. The computer 1100 includes, for example, a processor 1110, a main memory 1120, a storage 1130, and an interface 1140.

[0094] Each of the functional units of the determination device 40 described above is implemented in a computer 1100. The operation of each of the functional units described above is stored in the form of a program in a storage 1130. The processor 1110 reads the program from the storage 1130, loads it into the main memory 1120, and executes the above-described processing in accordance with the program. The processor 1110 also allocates storage areas in the main memory 1120 to be used by each of the functional units described above in accordance with the program.

[0095] The program may be for realizing some of the functions to be performed by the computer 1100. For example, the program may be combined with other programs already stored in the storage 1130 or other programs implemented in other devices to perform the functions. Furthermore, the computer 1100 may include a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to or instead of the above configuration. Examples of PLDs include a PAL (Programmable Array Logic), a GAL (Generic Array Logic), a CPLD (Complex Programmable Logic Device), and an FPGA (Field Programmable Gate Array). In this case, some or all of the functions to be performed by the processor 1110 may be realized by the integrated circuit.

[0096] Examples of storage 1130 include a magnetic disk, a magneto-optical disk, and a semiconductor memory. Storage 1130 may be an internal medium directly connected to the bus of computer 1100, or an external medium connected to computer 1100 via interface 1140 or a communication line. When this program is distributed to computer 1100 via a communication line, computer 1100 that receives the program may load the program into main memory 1120 and execute the above-mentioned processing. The program may also be a program for realizing part of the above-mentioned functions. Furthermore, the program may be a program that realizes the above-mentioned functions in combination with another program already stored in storage 1130, i.e., a so-called differential file (differential program).
