And an instruction from the inspection unit 70 is given to the electric wire instruction unit 26 via the input / output interface 76.

  The communication interface 75 is connected to the communication interfaces 62 of the plurality of pin inspection state control units 60 via the communication line 52 (serial communication line or the like), whereby the inspection unit 70 and each pin inspection state control unit 60 are mutually connected. It is connected so that it can communicate.

  As the communication interfaces 75 and 62, for example, a token circulates through the communication interface 75 of the inspection unit 70 and the communication interface 62 of the plurality of pin inspection state control units 60, and the communication interface 75, When the token 62 receives the token, it is possible to use a type that sends a signal to the communication network. In this case, each time the token makes a round, one instruction is given from the inspection unit 70 to the plurality of pin inspection state control units 60, and a certain instruction to the inspection unit 70 from the plurality of pin inspection state control units 60 is given. One response will be returned.

  FIG. 7 is a block diagram showing the pin inspection state control unit 60. The pin inspection state control unit 60 is configured to be switchable between a state in which an inspection voltage is applied to the plurality of pins 40 and a state in which the voltage state of the plurality of pins 40 is acquired.

  That is, the pin inspection state control unit 60 includes a pin control unit 61, a communication interface 62, an electric wire instruction unit output unit 63, and a pin input / output unit 64. The pin control unit 61 is configured to be able to communicate with the inspection unit 70 through the communication interface 62, and according to a command from the inspection unit 70, the state of each pin 40 is switched and each pin is switched via the pin input / output unit 64. 40 is acquired, and the electric wire indicator 26 is driven to emit light via the electric wire indicator output unit 63.

  The output part 63 for electric wire instruction | indication parts has the some output port 63a (here number 1-m) which can be switched between a high voltage state and a low voltage state. Each output port 63a is connected to one end portion of the wire instruction portion 26 associated with each terminal insertion portion 17 of each connector 16 set in the connector setting portion 30 via a resistor R1. Further, the other end portion of the electric wire instruction unit 26 is connected to a high voltage in the pin inspection state control unit 60. And according to the instruction | indication of the test | inspection unit 70, the output port 63a is controlled separately, and the electric wire instruction | indication part 26 corresponding to this light-emits by switching either to a low voltage state.

  The pin input / output unit 64 has a plurality of input / output ports 64a (here, numbers 1 to n) that can be switched between an input state and an output state.

  FIG. 8 is a block diagram conceptually showing an input / output switching circuit in one input / output port 64a. That is, the input / output line I / O is connected to the input terminal of the 3-state buffer B1 and to the output terminal of the 3-state buffer B2. The output terminal of the 3-state buffer B1 and the input terminal of the 3-state buffer B2 are commonly connected to the input terminal of the NOT circuit N1 and the output terminal of the NOT circuit N2. The output terminal of the NOT circuit N1 is connected to the pin 40 and is connected to a power supply line which is a high voltage via a pull-up resistor R2. The input terminal of the NOT circuit N2 is connected to the output terminal of the NOT circuit N1 through the resistor R3, and is connected to the ground line which is a low voltage line through the Zener diode D. A DIR line as a control input line is connected to one input terminal of the AND circuit A1 and to one inverting input terminal of the AND circuit A2. Further, the other control input line / OE line is connected to the other inverting input terminal of the AND circuit A1 and to the other inverting input terminal of the AND circuit A2. The output terminal of the AND circuit A1 is connected to the control input terminal of the 3-state buffer B1, and the output terminal of the AND circuit A2 is connected to the control input terminal of the 3-state buffer B2.

  When the / OE line is in a low voltage state and the DIR line is in a low voltage state, a low-level control signal is applied to the 3-state buffer B1, and the 3-state buffer B1 enters a high impedance state. The high-level control signal of the state buffer B2 is given, and the 3-state buffer B2 operates as a normal buffer. As a result, an input corresponding to the voltage state of the pin 40 is input to the input / output line I / O via the NOT circuit N2 and the two-state buffer B2. This state is a state in which an inspection voltage (here, a high voltage) is applied to each pin 40.

  On the other hand, when the / OE line is in a low voltage state and the DIR line is in a high voltage state, a high level control signal is given to the 3-state buffer B1, and the 3-state buffer B1 operates as a normal buffer. When the low level control signal of the 3-state buffer B2 is applied, the 3-state buffer B2 enters a high impedance state. As a result, an output corresponding to each state of the high signal and low signal of the input / output line I / O is output to the pin 40 via the three-state buffer B1 and the NOT circuit N1. This state is a state in which the voltage state of each pin 40 is acquired.

  Here, changes in the voltage state of each pin 40 in the initial state, abnormal state, and conductive contact state with respect to the terminal 14 will be described.

  FIG. 9 is a diagram showing an initial state of the pin 40, and FIG. 10 is a diagram showing a state in which each input / output port 64a is switched to the input state.

  In the state shown in FIG. 10, since each pin 40 is connected to the power supply line via the pull-up resistor R2, each pin 40 is maintained in a high voltage state, and a high level signal is input to the input / output port 64a. Is done. In this state, if the pin 40 is grounded for some reason, each pin 40 is in a low voltage state, and a low level signal is input to the input / output port 64a. Therefore, in the initial state, the input / output port 64a is switched to the input state, and when a low level signal is input in this state, an initial abnormality can be detected.

  FIG. 11 is a diagram illustrating a state in which a conduction state between a plurality of pins 40 belonging to the first group and a plurality of pins 40 belonging to the second group is inspected. In this case, the input / output ports 64a corresponding to the plurality of pins 40 belonging to the first group are switched to the output state and a low level signal is output (see the left side of FIG. 11). That is, the test voltage (low voltage) is applied to all the plurality of pins 40 belonging to the first group. On the other hand, the input / output ports 64a corresponding to the plurality of pins 40 belonging to the second group are switched to the input state. That is, the voltage states of the plurality of pins 40 belonging to the second group are individually acquired.

  In the above state, when any of the plurality of pins 40 belonging to the first group is electrically connected to any of the plurality of pins 40 belonging to the second group, that is, the terminal insertion portion 17 corresponding to the two pins 40. When the terminals 14 at both ends of the common electric wire 12 with terminal are inserted and connected, a low level signal is inputted to the input / output port 64a corresponding to the pin 40 belonging to the second group. On the other hand, among the plurality of pins 40 belonging to the second group, those other than the pin 40 continue to receive a high level signal. For this reason, it is possible to specify that the low level signal input among the plurality of pins 40 belonging to the second group is conducted to any of the plurality of pins 40 belonging to the first group.

  By switching the first group and the second group and conducting a continuity test in the same manner as described above, a plurality of pins 40 belonging to the first group to which a low level signal is input belong to the second group It can be specified that it is electrically connected to one of the plurality of pins 40.

  From these identification results, as will be described later, it is possible to identify which pins 40 are in a conductive state between the first group and the second group.

<3. Processing of inspection unit>
Processing of the inspection unit 70 will be described. The inspection unit 70 executes work procedure instruction processing, and also performs conduction state inspection processing and erroneous insertion determination processing. More specifically, during the execution of the work procedure instruction process, the conduction state inspection process and the erroneous insertion determination process are executed. Here, after describing the work procedure instruction process and the work procedure according to the process, the conduction state inspection process and the erroneous insertion determination process will be described.

<3.1. Work procedure instruction processing>
FIG. 12 is a flowchart showing work procedure instruction processing. According to the work instruction data 74b, the work procedure instruction process controls the display of the electric wire instruction section 26, the terminal insertion position instruction section 32, etc., thereby instructing the order of taking out the electric wires 12 with terminals, the extraction position, the insertion position of the terminals 14, and the like. It is a process to do. In the work instruction data 74b, work procedures are stored separately for the work area 22A (series 1) and the work area 22B (series 2) as described above. Then, by combining the work series of both series, a work instruction for one work series can be given, and the work procedure can also be instructed in two work series. A configuration in which work procedures are stored and instructed by dividing into a larger number of work sequences may be employed. Further, the work procedure may be stored and instructed by one work sequence from the beginning.

  That is, when the erroneous insertion inspection apparatus 20 is activated by an operation on the activation switch or the like, a predetermined activation process such as an initial reset process is executed in step S1, and then the process proceeds to step S2.

  In step S2, it is determined whether the operation is a single operation or a plurality of operations based on a command via the input device or the like. If it is determined that the operation is a single operation, the processing of steps S11 to S18 is executed. If it is determined, the processes in steps S21 to S28 and the processes in steps S31 to S38 are performed in parallel. Note that the parallel processing may be performed by a plurality of CPUs performing parallel processing separately or by a single CPU performing pseudo parallel processing.

  In step S11, a conduction state inspection process is executed. The main process in this conduction state inspection process is a process for acquiring the conduction relationship of the pins 40, which will be described in detail later.

  In step S12, the terminal-attached electric wire 12 to be taken out is specified according to the work instruction data 74b, and a display instruction is given to the electric wire instruction unit 26 corresponding to the semi-cylindrical member 24a that accommodates the terminal-attached electric wire 12. Further, the pin number corresponding to the terminal insertion portion 17 into which the terminal 14 at the A end of the terminal-attached electric wire 12 is to be inserted is specified, and the pin insertion state indicating unit 32 corresponding to the pin number is passed through the pin inspection state control unit 60. A display instruction is given.

  In the next step S13, based on the detection signal from the tension detection unit 37, it is determined whether or not the A-end tensile test has passed, that is, whether or not the terminal 14 is completely inserted into the terminal insertion unit 17. The If it is determined that the A-end tensile test has passed, the process proceeds to the next step S14.

  In step S <b> 14, based on the detection signal from the B-end touch plate 28, it is determined whether or not the B-end terminal 14 touches the B-end touch plate 28. If it is determined that there is no touch of the B-end terminal 14 on the B-end touch plate 28 within a predetermined time, the process returns to step S12 and the above processing is repeated. That is, the operation of taking out the terminal-attached electric wire 12 and inserting and connecting the terminal 14 at the A end is instructed again. On the other hand, if it is determined that the B-end terminal 14 touches the B-end touch plate 28, the process proceeds to the next step S15.

  In step S15, an erroneous insertion determination process is executed. The main process in the erroneous insertion determination process is a process for determining whether or not the terminal-attached electric wire 12 is erroneously inserted based on the continuity relationship between the pins 40 acquired in step S11 and the work instruction data 74b. To do.

  In the next step S16, the pin number corresponding to the terminal insertion portion 17 into which the terminal 14 at the B end of the electric wire 12 with terminal is to be inserted is specified, and the terminal insertion position instruction corresponding to the pin number is specified through the pin inspection state control unit 60. A display instruction is given to the unit 32.

  In the next step S <b> 17, based on the detection signal from the tension detection unit 37, it is determined whether or not the B-end tensile test has passed, that is, whether or not the terminal 14 is completely inserted into the terminal insertion unit 17. The If it is determined that the B-end tensile test has passed, the process proceeds to the next step S18.

  In step S18, it is determined whether or not all work has been completed, that is, whether or not all the insertion and connection work for each terminal 14 of the terminal-attached electric wire 12 has been completed. If it is determined that all the work has not been completed, the process returns to step S11, and after the conduction state inspection process is performed, the processes in and after step S12 are executed for the next terminal-equipped electric wire 12. If it is determined that all work has been completed, the process proceeds to step S3, where a predetermined end process S3 is executed and the process ends.

  In the above description, it is assumed that the terminals 14 at both ends of the terminal-attached electric wire 12 are connected to the terminal insertion portion 17. However, when only the terminal 14 at one end of the terminal insertion portion 17 is connected. After step S13 is completed, the process returns to step S11 or step S12 and the following processing is repeated.

  Since the processes of steps S21 to S28 and the processes of steps S31 to S38 that are processed in parallel are substantially the same as steps S11 to S18, respectively, the description thereof is omitted.

<3.2. Work procedure>
FIG. 13 is a flowchart showing a work procedure viewed from the worker side. That is, it is assumed that two workers A and B work separately in the work areas 22A and 22B, respectively.

  In this case, in step S41, the workers A and B input a plurality of operations via an input device or the like. Then, as described above, various instructions, inspections, and the like are executed separately in the work areas 22A and 22B.

  In step S51, the worker A confirms the instruction of the electric wire instruction unit 26 and takes out the electric wire 12 with terminal. In addition, it is good to prepare the electric wire accommodating part 24 for the work area 22A and the work area 22B separately.

  Next, in step S52, the worker A confirms the instruction of the terminal insertion position instruction section 32, and the terminal 14 at the A end of the taken-out electric wire with terminal 12 is moved to the terminal insertion section 17 at a position corresponding to the instruction. Insert and connect. And it pulls the electric wire 12 with a terminal inserted and connected, and confirms whether it passed the tension test.

  Next, in step S <b> 53, the worker A brings the terminal 14 at the B end of the terminal-attached electric wire 12 into contact with the B-end touch plate 28.

  Next, in step S54, the worker A confirms the instruction of the terminal insertion position instruction section 32, and inserts and connects the terminal 14 at the B end of the terminal-attached electric wire 12 to the terminal insertion section 17 at a position corresponding to the instruction. To do. And it pulls the electric wire 12 with a terminal inserted and connected, and confirms whether it passed the tension test.

  In step S54, if the instructed insertion and connection destination of the terminal 14 at the B end is within another work area 22B, the process returns to step S51 to take out another electric wire 12 with a terminal and What is necessary is just to continue the process in 22A. For that purpose, it is preferable to cancel the B-end instruction (see step S16) by detecting the touch to the B-end touch plate 28 again, and return to the electric wire instruction and the A-end instruction (step S12) to execute the processing. . Here, the processing will be described on the assumption.

  In step S55, it is determined whether or not the area work 22A has been completed. That is, when there is an instruction for another terminal-attached electric wire 12, the process returns to step S51 and the demand period work is repeated. On the other hand, if there is no instruction for another terminal-attached electric wire 12, the process proceeds to step S42.

  The worker B in the work area 22B is similarly operated in steps S61 to S65.

  When both workers A and B proceed to step S42, the operations in both areas are finished, and the next connecting operation is started (step S43). That is, in step S56, the worker A brings the terminal 14 at the B end of the terminal-attached electric wire 12 from the work area 22B (work sequence 2 side) into contact with the B-end touch plate 28 on the work area 22A side.

  Then, in the work area 22A, the terminal insertion position instruction unit 32 corresponding to the terminal insertion unit 17 to which the terminal 14 is to be inserted and connected displays, so in step S57, the terminal insertion unit 17 is connected to the terminal insertion unit 17 using the display as a clue. 14 is inserted and connected, and a tensile test is performed.

  In step S58, the worker A determines whether or not there is a linked work from the work area 22B (work sequence 2 side). That is, if there is an uninserted terminal 14 in the work area 22B (work sequence 2 side), the worker A brings it into contact with the B-end touch plate 28. Then, in the work area 22A, if the terminal insertion position instruction unit 32 is displayed, the presence of the insertion target can be recognized, and if this is repeated and it is confirmed that there is no display of the terminal insertion position instruction unit 32, the connection work is completed. I can judge.

  Also in the work area 22B, the connecting work is performed in the same manner as described above in steps S66 to S68.

  Thereby, when all the connection work is completed (refer to Step S44), final confirmation by visual inspection and the like are performed, and the temporarily joined part 18 is manufactured.

  In the above example, the connection work between the work areas 22A and 22B is performed at the end, but the connection work may be performed every time connection work to another area occurs.

<3.3. Conduction state inspection process>
FIG. 14 is a flowchart showing the continuity inspection process. As the continuity inspection process, the inspection unit 70 inspects the continuity state between the entire plurality of pins 40 belonging to the first group (group on the A end side) and the individual plurality of pins 40 in the second group (group on the B end side). At the same time, the group is switched, that is, the conduction state is inspected between the entire plurality of pins 40 belonging to the second group and the individual plurality of pins 40 belonging to the first group. In this continuity inspection process, when the terminal-attached electric wires 12 are sequentially connected, the continuity relationship between the plurality of pins 40 is specified for the pins 40 excluding the continuity-confirmed pins 40. Further, among the pins 40, the pins 40 corresponding to the empty terminal insertion portions 17 into which the terminals 14 are not inserted in the manufacturing process of the temporary connection part 18 may be handled as belonging to either the first group or the second group. However, it may be handled as belonging to none.

  With reference to FIG. 14, the continuity test process will be described more specifically.

  First, in step S71. The inspection unit 70 acquires the ground state of all the pins 40 through each pin inspection state control unit 60 as an initial inspection. In other words, the inspection unit 70 switches all the pins 40 to the input state and gives a command to each pin inspection state control unit 60 to acquire the voltage state of each pin 40, and is transmitted from each pin inspection state control unit 60. The voltage state of each pin 40 is acquired. At this time, as described with reference to FIG. 10, since all the pins 40 are connected to the power supply line via the pull-up resistor R2, the input / output port 64a has a high level in the normal state. A signal is input. On the other hand, when the pin 40 is connected to the ground due to some trouble, a low level signal is input to the input / output port 64a. The initial voltage state of each pin 40 is written into the flash memory as initial voltage data.

  Next, in step S72, the inspection voltage is applied to all the B-end pins 40 belonging to the second groove (that is, the corresponding input / output port 64a is switched to the output state and the low voltage is output). To each pin inspection state control unit 60. This instruction is given as a state switching instruction from the inspection unit 70 to each pin inspection state control unit 60 at once, that is, in a cycle in which the token makes a round of each pin inspection state control unit 60 and the like. As a result, a common test voltage (low voltage) is applied to the plurality of pins 40 belonging to the second group (B end side). In this state, the input / output port 64a corresponding to each pin 40 for the A end remains in the input state.

  In the next step S73, a command is given to each pin inspection state control unit 60 in a lump so as to acquire the individual voltage state of each pin 40 for A end belonging to the first group. As a result, the individual voltage states of the plurality of pins 40 belonging to the first group are acquired in a state where the test voltage common to the plurality of pins 40 belonging to the second group is applied. The above command is also given from the inspection unit 70 to each pin inspection state control unit 60 in a lump, and the token is then transmitted to each pin inspection state control unit 60 along with the transmission of voltage information from each pin inspection state control unit 60. Transmission / reception is performed in a cycle that goes around the unit 60 and the like.

  Next, the processing of steps S75 and S76 is repeated from the beginning of the pin 40 for the A end (for example, the one with the smallest number) to the end of the pin 40 for the B end (for example, the one with the largest number). It is.

  That is, in step S75, whether or not the initial ground state of the pin 40 for the A-number of the target number is OK (that is, referring to the initial voltage state acquired in step S71, for the A-end of the corresponding number) And whether the pin 40 for the A terminal corresponding to the number is conductive (that is, whether or not the voltage state acquired in step S73 is a low voltage). Is done. When both conditions are satisfied (that is, when it is determined that there is no initial abnormality and conduction is present), the process proceeds to step S76, and the data of the number of the corresponding pin 40 is set in the A-end conduction data. On the other hand, when any of the conditions is not satisfied (that is, when it is determined that there is no initial abnormality or no continuity), step S76 is skipped, and the above-described processing is repeated for the pin 40 of the next number.

  Here, for example, as shown in FIG. 15, the A-end conduction data is information indicating each number of the A-end pin 40 and the inspection result (for example, “0” indicates no conduction and “1” indicates conduction). Are associated with each other. In the initial state, “0” (no continuity) is associated with all the numbers of the A-end pin 40, and “1” is set when it is determined in step S 46 that continuity is present. In the example shown in FIG. 15, “0” is not associated with “1”, “3”, “8” of the number of the pin 40 for the A end, and there is continuity for the number “6”. 1 "is associated. But you may abbreviate | omit the process of step S71. In this case, the result acquired in step S73 may be used as inspection determination data.

  When the processing of steps S74 to S77 is completed for all the A-end pins 40 subjected to the continuity state inspection, the process proceeds to step S78, and the plurality of A-end pins 40 belonging to the first group and the second group. The same processing as described above is performed by replacing the plurality of pins 40 for the B end belonging to.

  That is, the following steps S78 to S84 are the same as the above steps except that the plurality of pins 40 for A end belonging to the first group are replaced with the plurality of pins 40 for B end belonging to the second groove. This is the same processing as S71 to S77. Here, the description of steps S78 to S84 is omitted.

  As shown in FIG. 16, for example, as shown in FIG. 16, the B end conduction data obtained in steps S78 to S84 is information (for example, “0”) indicating each number of the B end pin 40 and the inspection result. "" Indicates no continuity and "1" indicates continuity). In the example shown in FIG. 16, “0” is not associated with the numbers “9”, “10”, and “12” of the pin 40 for the B end, and there is continuity for the number “2”. 1 "is associated. Of course, similarly to the above, the process of step S78 may be omitted, and the result obtained in step S80 may be used as data for inspection determination.

  In addition, steps S71 to S77, which are processes for inspecting the conduction states of the A-end pin 40, and steps S78 to S84, which are processes for inspecting the respective conduction states of the B-end pin 40, are replaced one after another. You may go.

<3.4. Misinsertion determination process>
FIG. 17 is a flowchart showing an erroneous insertion determination process. As the continuity inspection process, the inspection unit 70 includes a plurality of pins 40 on the A end side belonging to the first group and a plurality of pins on the B end side belonging to the second group based on the inspection result obtained in the continuity state inspection process. The presence or absence of erroneous insertion is determined by specifying the continuity relationship with 40.

  More specifically, in step S91, the pins 40 of the terminals 14 at both ends of the terminal-attached electric wire 12 into which the terminal 14 at the previous B end has been inserted (that is, a set of insertion target pins for which the previous insertion work instruction has been issued) are identified. To do. That is, in this embodiment, after the insertion position instruction of the terminal 14 at the B end of the electric wire 12 with terminal 12 in a certain order is given (see step S16 in FIG. 12), after the B end touch of the electric wire 12 with a terminal in the next order ( Between step S14 in FIG. 12) and the insertion position instruction for the B end (see step S16 in FIG. 12), the presence / absence of erroneous insertion of the previously connected terminal-attached electric wire 12 is determined. The terminal-attached electric wire 12 into which the terminal 14 at the B end is inserted last time is determined that the insertion operation of the terminal 14 at both ends is completed, that is, an instruction to insert the B end (see step S16 in FIG. 12). This is done by leaving the number history of what has been done (here, one that has been further passed in the tensile test) as temporary data. When the terminal-attached electric wire 12 into which the terminal 14 at the B-end of the previous time is inserted is identified, the number of the previous insertion target pin 40 can be specified by referring to the work instruction data 74b shown in FIG.

  In step S92, the A-side conduction pin 40 is specified with reference to the A-end conduction data shown in FIG. In the example illustrated in FIG. 15, the pin 40 with the number “6” is identified as being conductive.

  In step S93, the B-side conductive pin 40 is specified with reference to the B-end conductive data shown in FIG. In the example illustrated in FIG. 16, the pin 40 with the number “2” is identified as being conductive.

  That is, in steps S92 and S93, based on the individual conduction state of the plurality of pins 40 belonging to the first group which is the A end and the individual conduction state of the plurality of pins 40 belonging to the second group which is the B end. The conduction relationship can be specified. Here, it is determined that there is continuity between the pin numbers “6” and “2”.

  FIG. 18 is a table conceptually showing the A-end conduction data and the B-end conduction data, and the conduction relationship between both ends. In other words, the terminal numbers at the A end are assigned to the vertical column, the terminal numbers at the B end are assigned to the horizontal column, and each column is separated by a diagonal line, and the conduction state at the B end side at the upper right and the conduction at the A end side at the lower left. State the state. Note that “◯” indicates that conduction is present, and “x” indicates that conduction is absent. Then, when there is conduction between AB, both conduction states in each column are “◯” (conduction exists). When there is no continuity between AB, any of the two continuity states in each column is “x” (no continuity). Therefore, the conduction relationship between AB can be specified. If it is erroneously inserted, for example, if the terminal 14 is inserted at the position of the number “10” on the B-end side, the contents of () in FIG. 18 are obtained, and the numbers “6” and “10” It will be determined that there is a continuity relationship between them.

  In subsequent step S94, it is determined whether or not the number of the pin 40 determined to have the continuity relationship in steps S92 and S93 matches the number of the insertion target pin specified in step S91. For example, when it is determined in steps S92 and S93 that there is a conduction relationship between the numbers “6” and “2”, the numbers match the numbers “6” and “2” of the insertion target pin 40 (FIG. 5). It is determined that the work procedure 1). On the other hand, for example, if it is determined in steps S92 and S93 that there is a conduction relationship between the numbers “6” and 102 ”, it is determined that the numbers“ 6 ”and“ 2 ”of the insertion target pin 40 do not match. The

  If it is determined in step S94 that they match, the process proceeds to step S95, where it is determined as a pass determination (no erroneous insertion), and the erroneous insertion determination process is terminated.

  On the other hand, if it is determined in step S94 that they match, the process proceeds to step S96, where it is determined as a failure determination (with erroneous insertion). The determination result is notified to the worker through a notification device such as a display device. Preferably, the number of the pin 40 in an erroneous connection relationship is displayed. The worker who has recognized this confirms the connection relationship of the terminal-attached electric wires 12 that performed the previous connection work, and performs the reconnection work. Thereafter, the erroneous insertion determination process is terminated.

<4. Summary>
According to the erroneous insertion inspection device 20 and the erroneous insertion inspection method of the terminal-attached electric wire 12 configured as described above, the entire plurality of pins 40 belonging to the first group (for the A end) and the second group (for the B end) The conduction state is checked between the individual pins 40 belonging to each other, and the conduction state between the whole of the plurality of pins 40 belonging to the second group (for the B end) and the individual pins 40 belonging to the first group (for the A end) is checked. Inspect. More specifically, in a state where a common test voltage is applied to the plurality of pins 40 belonging to the first group, the individual voltage states of the plurality of pins 40 belonging to the second group are acquired to check the conduction state, and the first Similarly, the conduction state is inspected by switching between the first group and the second group. These conduction states can be acquired in a short time regardless of the number of pins 40 (even if the temporary connection part 18 is manufactured with 50 to 100 electric wires 12 with a terminal). Based on these inspection results, it is possible to specify the conduction relationship between the plurality of pins 40 belonging to the first group and the plurality of pins 40 belonging to the second group. As a result, it is possible to acquire the inspection information for performing the inspection of the erroneous insertion of the terminal-attached electric wire 12 in a shorter time.

  In addition, the inspection unit 70 performs a signal transmission between the inspection unit 70 and the pin inspection state control unit 60 in order to collectively instruct each pin inspection state control unit 60 to apply an inspection voltage, acquire a voltage state, and the like. Time can be shortened.

  In particular, since this apparatus issues an instruction to the terminal insertion position instruction unit 32, a relatively large amount of information is transmitted between the pin inspection state control unit 60 and the inspection unit 70. In such a case, as described above, the signal transmission time between the inspection unit 70 and the pin inspection state control unit 60 is shortened, so that the signal between the pin inspection state control unit 60 and the inspection unit 70 is shortened. There is a great advantage in that a transmission delay is prevented and an instruction to the terminal insertion position instruction unit 32 can be promptly performed.

  In addition, since this apparatus issues work instructions in a plurality of work sequences, communication is frequently performed between the pin inspection state control unit 60 and the inspection unit 70 with a larger amount of information. Therefore, as described above, signal transmission delay between the pin inspection state control unit 60 and the inspection unit 70 is prevented by shortening the signal transmission time between the inspection unit 70 and the pin inspection state control unit 60. In addition, there is an advantage that work instructions for a plurality of lines can be performed quickly.

{Modifications}
In the above embodiment, the description has been made assuming that the terminals 14 at both ends of the terminal-attached electric wire 12 are basically inserted into the terminal insertion portion 17. However, of course, only the terminal 14 at one end is inserted. Work instructions may be given. Such a terminal insertion portion 17 need not be inspected.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
