Here, the movement of the pushing member 60 toward the holder portion 30 side is restricted by the flange portion 62 coming into contact with the end portion of the large diameter portion 46 on the holder portion 30 side.

  Further, the pushing member 60 is configured to be relatively movable with respect to the main body 40 between the advance position and the retracted position (see FIG. 5). Further, the pushing member 60 is arranged in a state of being urged from the retracted position toward the advanced position by the pushing urging member 66 with respect to the main body portion 40. Here, the advancing position is a position where the flange portion 62 is in contact with the end portion on the holder portion 30 side of the large diameter portion 46 of the main body side insertion hole portion 48, in other words, the main body portion 40 is in contact with the holder portion 30. It is a position where the corresponding waterproof plug detecting member 50 is changed to the approach position in the state of being in the inspection position (see FIG. 5). Further, the retracted position is a position where the pushing biasing member 66 is compressed in a direction away from the holder part 30, in other words, in a state where the main body part 40 is in the inspection position with respect to the holder part 30. This is the position at which the waterproof plug detecting member 50 is maintained in the retracted posture (see FIG. 11). More specifically, in the internal space of the large-diameter portion 46 of the main body side insertion hole portion 48, a coil spring as a pressing biasing member 66 that is sheathed on the base end side portion of the flange portion 62 of the pressing member 60.

That is, the pushing member 60 is disposed so as to be moved by being pushed toward the holder portion 30 by the body portion 40 via the pushing biasing member 66 when the body portion 40 moves close to the holder portion 30. . Thereby, when the pushing member 60 is pressed from the holder part 30 side toward the main body part 40 side, it is retracted from the advanced position relative to the main body part 40 within the compression range of the pushing biasing member 66. The retraction movement is possible toward the position side.

  Then, when the main body portion 40 is moved from the set position to the inspection position with respect to the holder portion 30, the push member 60 protrudes into the detection member accommodation recess 36 through the holder side insertion hole portion 38. . At this time, the pressing member 60 presses the contact portion 56 of the waterproof plug detecting member 50 disposed at a position facing the holder side insertion hole 38. That is, the pushing member 60 applies a force to the waterproof plug detecting member 50 in a direction in which the posture is changed from the retracted posture to the approaching posture. Here, when the waterproof plug P1 is not inserted into the first hole portion 14a or the second hole portion 14b of the housing main body 12 housed in the holding recess 32, the pushing member 60 is the pushing biasing member 66. The abutting portion 56 is pushed in a state where the main body portion 40 is maintained at the advanced position by the urging force. Accordingly, the waterproof plug detecting member 50 is changed in posture to the approach posture in which the protruding portion 52 has advanced into the first hole portion 14a or the second hole portion 14b (see FIG. 5). In addition, when the waterproof plug P1 is inserted, the waterproof plug detection member 50 is maintained in the retracted posture with the protruding portion 52 in contact with the waterproof plug P1. As a result, the pushing member 60 is pushed toward the main body 40 by the contact portion 56, and the pushing biasing member 66 is contracted and deformed to be relatively moved with respect to the main body 40 from the advanced position to the retracted position. (See FIG. 11). The pushing member 60 is configured to change the posture of the waterproof plug detecting member 50 between the approaching posture and the leaving posture as described above.

  The waterproof inspection circuit unit 70 is configured to be conductive in accordance with the postures of the plurality of waterproof plug detection members 50. More specifically, the waterproof inspection circuit unit 70 includes a plurality (three in this case) of switch units 72 that can be switched on and off, corresponding to the first hole part 14a or the second hole part 14b.

The base end portion of 60 is disposed so as to be switched on and off by pushing the action portion 73 (see FIG. 3). More specifically, the switch portion 72 is arranged so that the action portion 73 is positioned at a front position of the opening on the opposite side of the inspection recess 42 in the main body side insertion hole 48 (position facing the opening). It is installed. That is, the switch portion 72 is located at a position where the action portion 73 is pushed into the main body by the proximal end portion of the pushing member 60 in a state where the pushing member 60 compresses the pushing biasing member 66 and is moved to the retracted position. It is arranged. Here, the plurality of switch parts 72 are fixed in parallel to the main body part 40 by screws or the like in a state of being partially accommodated in a switch arrangement recess 49 formed in the main body part 40. . The fixed posture of the switch portion 72 is a posture in which the pushing direction of the action portion 73 is substantially orthogonal to the moving direction of the pushing member 60.

  Further, a tapered portion 68 having a gradually decreasing diameter toward the proximal end side is formed at the proximal end portion of the pushing member 60 (see FIG. 3). Thereby, even in the case of the configuration of the present embodiment in which the moving direction of the pushing member 60 and the pushing direction of the action portion 73 are substantially orthogonal, the switch portion 72 can be switched on and off more reliably by operating the action portion 73. it can.

  Then, the plurality of pushing members 60 switch on and off the corresponding switch portions 72 according to the postures of the plurality of waterproof plug detecting members 50 in a state where the holder portion 30 is moved to the inspection position with respect to the main body portion 40. It is configured to be operable. More specifically, each pushing member 60 is retracted when the corresponding waterproof plug detecting member 50 is maintained in the retracted position when the holder portion 30 and the main body portion 40 are moved from the set position to the inspection position. It moves to a position and pushes in the action part 73 of the corresponding switch part 72 (refer FIG. 5). Each pusher member 60 is maintained at the advanced position where it does not act on the action portion 73 when the corresponding waterproof plug detecting member 50 is changed to the approach posture (see FIG. 11).

  The waterproof inspection circuit unit 70 is configured by connecting the plurality of switch units 72 in series by a conductive wire or the like (see FIG. 9). That is, the waterproof inspection circuit unit 70 is electrically connected as a whole when all of the plurality of switch units 72 are electrically closed.

  The waterproof determination unit 80 can determine whether or not the waterproof plug is inserted into the first hole part 14a or the second hole part 14b according to the postures of the plurality of waterproof plug detection members 50. More specifically, the waterproof determination unit 80 is configured to determine whether or not the waterproof plug P1 is inserted into the first hole part 14a or the second hole part 14b depending on whether or not the waterproof test circuit unit 70 is conductive. ing. This waterproof determination unit 80 is connected in series to the waterproof test circuit unit 70, and is set so that the waterproof test circuit unit 70 determines that it is good in the conductive state and determines that it is bad in the non-conductive state. (See FIG. 9). As a structure of the waterproof determination part 80, display apparatuses, such as a liquid crystal display which can display a power supply, a light bulb, a buzzer, or a quality, for example, are employable.

  Further, in the waterproof connector inspection apparatus 20 according to the present embodiment, the plurality of switch units 72 are set to be set to be electrically opened in the off state and to be closed. Are appropriately adopted. In the inspection stage, the first hole portion 14a in which the waterproof plug P1 should be disposed is preferably determined to be good when the waterproof plug P1 is disposed, and the waterproof plug P1 should not be disposed. It is preferable to determine that the second hole portion 14b is good when the waterproof plug P1 is not provided. That is, the switch unit 72 should be adopted as appropriate in response to this request.

  Here, among the plurality of switch portions 72, the first switch portion 72p disposed corresponding to the first hole portion 14a is set to be in an open state in an off state (NO), The 2nd switch part 72e arrange | positioned corresponding to the 2nd hole part 14b is set so that it may be in an electrically closed state in an OFF state. FIG. 9 shows a plurality of switch units 72 when the waterproof connector 10 shown in FIG. 1 is an inspection target of the waterproof connector inspection device 20.

  That is, in the first switch portion 72p, when the waterproof plug P1 is disposed in the first hole portion 14a, the waterproof plug detection member 50 is maintained in the retracted position, and the pushing member 60 is moved to the retracted position. As a result, the action part 73 is pushed in (turned on) to be electrically closed. Further, when the waterproof plug P1 is not disposed in the first hole portion 14a, the first switch portion 72p changes the posture of the waterproof plug detection member 50 to the entry posture, and the push member 60 is maintained at the advance position. Therefore, the action portion 73 is not pushed in (maintained in the off state) and is electrically maintained in the open state.

  On the other hand, the second switch portion 72e is turned on and electrically opened when the waterproof plug P1 is disposed in the second hole portion 14b. In addition, when the waterproof plug P1 is not provided in the second hole portion 14b, the second switch portion 72e is maintained in the off state and is electrically closed.

  The terminal insertion inspection unit 90 includes a terminal detection member 92 and a terminal insertion determination unit 96 (see FIG. 8). The terminal insertion inspection portion 90 is configured to be able to inspect whether or not the waterproof plug crimping electric wire 18 is inserted into the third hole portion 14 c formed in the housing main body portion 12 of the waterproof connector 10. More specifically, the terminal insertion inspection unit 90 can inspect whether or not the terminal T of the waterproof plug crimping electric wire 18 is satisfactorily accommodated in the tip side portion of the third hole 14c.

  The terminal detection member 92 is a waterproof plug inserted into the plurality of third hole portions 14c of the waterproof connector 10 held by the holder portion 30 in a state where the main body portion 40 is in the proximity of the holder portion 30. It arrange | positions so that it can contact with respect to the terminal T of the crimped electric wire 18 from the front end side of the waterproof connector 10 (refer FIG. 3, FIG. 5). A plurality (three in this case) of terminal detection members 92 are disposed in the main body 40 corresponding to the plurality of third holes 14 c of the waterproof connector 10.

  Here, the terminal detection member 92 is a conduction probe configured to be in an electrically closed state in a state where a contact portion 92a provided at a tip portion thereof is in contact with an object. Here, the state in which the contact portion 92a is in contact with the object refers to a state in which the contact portion 92a is in contact with and pressed against the object.

  The plurality of terminal detection members 92 are respectively main bodies so as to project the contact portions 92a into the inspection recesses 42 at positions facing the tip portions of the respective third holes 14c of the waterproof connector 10 held by the holder portion 30. The unit 40 is disposed. That is, each terminal detection member 92 has a contact portion 92a in the third hole portion 14c of the housing main body portion 12 disposed in the holding recess 32 in a state where the holder portion 30 and the main body portion 40 are in the inspection position. It is inserted through the distal end side opening, and is disposed so as to contact the terminal T of the waterproof plug crimping electric wire 18 disposed therein. The terminal detection member 92 is electrically closed with the contact portion 92a in contact with the terminal T.

  The plurality of terminal detection members 92 are connected in series by conducting wires or the like (see FIG. 8). A circuit to which the plurality of terminal detection members 92 are connected is referred to as a terminal insertion inspection circuit unit 94. The terminal insertion inspection circuit unit 94 is conductive as a whole in a state where all of the plurality of terminal detection members 92 are conductive.

  The terminal insertion determination unit 96 is configured to be able to determine whether or not the waterproof plug crimped electric wire 18 is inserted into the third hole 14c of the waterproof connector 10 according to whether or not the plurality of terminal detection members 92 are conductive. More specifically, the terminal detection member 92 is connected in series to the terminal insertion inspection circuit unit 94, and the terminal insertion inspection circuit unit 94 is determined to be good in the conductive state and is determined to be defective in the non-conductive state. It is set to be. As the configuration of the terminal insertion determination unit 96, the same configuration as the configuration of the waterproof determination unit 80 can be adopted.

  So far, the waterproof connector inspection apparatus 20 has been described with an example in which the waterproof connector 10 shown in FIG. 1 is an inspection object, but the waterproof connector inspection apparatus 20 is not limited to this. The waterproof connector inspection device 20 includes, for example, the waterproof connector 10 in which the waterproof plugs P1 are disposed in all the holes 14 on one row of the housing main body 12 (all the rows are the first holes 14a), or The waterproof connector 10 in which neither the waterproof plug crimping electric wire 18 nor the waterproof plug P1 is provided in all the holes 14 in one row (all the rows are the second holes 14b) can be inspected. In this case, the first switch portion 72a or the second switch portion 72b may be provided depending on whether or not the waterproof plug P1 needs to be inserted into the hole portion 14.

  Moreover, the structure which the waterproof determination part 80 determines the presence or absence of insertion of the waterproof stopper P1 with respect to the 1st hole part 14a or the 2nd hole part 14b is not restricted above. For example, the waterproof determination unit 80 may be configured to directly detect the posture change of the waterproof plug detecting member 50 using a contact-type sensor including various distance sensors, microswitches, and the like. That is, in the state where the main body 40 is in the inspection position with respect to the holder 30, it is detected whether the waterproof plug detecting member 50 is in the approaching posture or the retracting posture, and the first hole portion 14 a or the second hole portion 14 b. What is necessary is just to determine the presence or absence of insertion of the waterproof plug P1 with respect to.

<3. Operation of Waterproof Connector Inspection Device>
Next, the operation of the waterproof connector inspection apparatus 20 will be described with reference to FIGS. 5, 10, and 11.

  In the description of the operation, the waterproof connector inspection device 20 will be described as being in the following initial state (see FIG. 10). The main body portion 40 is located at a set position separated from the holder portion 30. The plurality of waterproof plug detecting members 50 are each maintained in the retracted posture by the urging force of the urging member 58 for eviction. Further, each of the plurality of pushing members 60 is pressed against the holder part 30 side by the urging force of the pushing urging member 66 and does not act on the action part 73 of the corresponding switch part 72 (the base end part is It is maintained in a state (located at the position on the holder portion 30 side) with respect to the action portion 73.

  First, the operator sets the waterproof connector 10 to be inspected to the holder portion 30 (see FIGS. 6 and 10). More specifically, the housing main body portion 12 of the waterproof connector 10 is disposed in the holding recess 32 through the opening, and the electric wires W extending from the housing main body portion 12 are disposed in the slit portion 34. The holder part 30 is extended to the outside. In this state, the waterproof connector 10 is arranged such that the base end portions of the first hole portion 14a and the second hole portion 14b face the opening of the detection member housing recess 36 (the protruding portion 52 of the waterproof plug detection member 50). And is held by the holder portion 30 in a state where the tip portions of the plurality of hole portions 14 are exposed at the tip side of the holder portion 30.

  After setting the waterproof connector 10 to the holder part 30, the operator operates the operation lever 24 to move the main body part 40 closer to the holder part 30 from the set position to the inspection position.

  In the waterproof connector inspection apparatus 20, the waterproof inspection and the terminal insertion inspection are performed substantially simultaneously with the proximity movement of the main body 40 to the holder 30. Therefore, after first explaining the waterproof test, the terminal insertion test will be explained.

  Along with the close movement, the plurality of pushing members 60 gradually move through the holder side insertion hole portion 38 toward the holder portion 30 side. Further, when the main body 40 is moved close to the holder 30, the distal end portions of the plurality of pushing members 60 protrude into the detection member housing recess 36 through the openings and the contact portions 56 of the waterproof plug detection member 50. Abut.

  When the main body portion 40 is further moved from the position where the pushing member 60 abuts against the abutting portion 56 of the waterproof plug detecting member 50, the plurality of pushing members 60 respectively press the corresponding abutting portions 56 to waterproof. A force is applied to the stopper detection member 50 in a direction to change the posture from the leaving posture to the approaching posture. After that, the plurality of waterproof plug detecting members 50 and the plurality of pushing members 60 corresponding thereto operate according to whether or not the waterproof plug P1 is inserted into the corresponding first hole portion 14a or second hole portion 14b. .

  First, the operation of the waterproof plug detecting member 50 and the pushing member 60 corresponding to the first hole portion 14a or the second hole portion 14b in a state where the waterproof plug P1 is not inserted will be described (see FIG. 5). The pushing member 60 pushes the contact portion 56 of the waterproof plug detecting member 50 with the movement of the main body 40 while being maintained at the advanced position with respect to the main body 40. Thereby, the waterproof plug detecting member 50 is changed in posture from the leaving posture to the entering posture. More specifically, the waterproof plug detecting member 50 is changed in posture around the support shaft portion 51 by the abutting portion 56 being pushed in the direction opposite to the protruding direction, and the protruding portion 52 is held through the opening. It moves forward into the recess 32. That is, the protrusion 52 enters the first hole portion 14 a or the second hole portion 14 b formed in the housing main body portion 12 disposed in the holding recess 32 from the proximal end side opening. And when the main-body part 40 is moved to the test | inspection position with respect to the holder part 30, the waterproof plug detection member 50 will be in the state by which the attitude | position change was completely made into the approach attitude | position. Even in this state, the pushing member 60 is disposed at the advanced position and does not act on the action portion 73. That is, the switch unit 72 is maintained in the off state.

  Next, the operation of the waterproof plug detecting member 50 and the pushing member 60 corresponding to the first hole portion 14a or the second hole portion 14b in a state where the waterproof plug P1 is inserted will be described (see FIG. 11). The waterproof plug detecting member 50 attempts to change the posture from the leaving posture to the entering posture by the pressing force of the pushing member 60. Then, the protruding portion 52 of the waterproof plug detecting member 50 comes into contact with the waterproof plug P1 provided in the first hole portion 14a or the second hole portion 14b of the housing main body portion 12 provided in the holding recess 32. The posture change is stopped. Here, the waterproof plug detection member 50 is slightly changed in posture until it comes into contact with the waterproof plug P1. Note that the posture in contact with the waterproof plug P1 is also the exit posture. When the waterproof plug detecting member 50 is stopped in the retracted posture, the pushing member 60 is restricted from moving toward the holder portion 30 at the position where the pushing member 60 is in contact with the contact portion 56. The pushing biasing member 66 is compressed and retracted relative to the main body 40. Along with this retreating movement, the base end portion of the pushing member 60 comes into contact with the action portion 73 of the switch portion 72 and gradually pushes the action portion 73 along the inclination of the taper portion 68. And if the main-body part 40 is moved to the test | inspection position with respect to the holder part 30, the pushing member 60 will move to the retracted position which pushed the action part 73, and will switch the switch part 72 to an ON state.

  When the hole portion 14 is the first hole portion 14a, the corresponding first switch portion 72p is maintained in an electrically open state without the waterproof plug P1 being inserted into the first hole portion 14a. It is electrically switched to the closed state with P1 inserted.

  When the hole 14 is the second hole 14b, the corresponding second switch part 72e is maintained in an electrically closed state in a state where the waterproof plug P1 is not inserted into the second hole 14b, and is waterproof. With the plug P1 inserted, it is electrically switched to the open state.

  When the waterproof plug P1 is inserted into the first hole portion 14a and the waterproof plug P1 is not inserted into the second hole portion 14b, the plurality of switch portions 72 are all electrically closed, and the waterproof inspection circuit portion 70 Becomes conductive (see FIG. 9). And the waterproof determination part 80 is the presence or absence of insertion of the waterproof plug P1 with respect to all the 1st hole parts 14a and the 2nd hole parts 14b of the waterproof connector 10 to be test | inspected by conduction | electrical_connection of the waterproof test | inspection circuit part 70. Judge as good.

  Further, when any one of the first hole portions 14a is not inserted with the waterproof plug P1, or when one of the second hole portions 14b is inserted with the waterproof plug P1, the first hole portion 14a or The first switch part 72p or the second switch part 72e corresponding to the second hole part 14b is electrically opened. As a result, the waterproof inspection circuit unit 70 becomes non-conductive as a whole. The waterproof determination unit 80 determines whether the waterproof plug P1 is inserted into the first hole portion 14a and the second hole portion 14b of the waterproof connector 10 to be inspected due to the non-conduction of the waterproof inspection circuit unit 70. Is determined.

  Next, the terminal insertion inspection will be described. As the main body portion 40 moves closer to the holder portion 30, the contact portions 92 a of the plurality of terminal detection members 92 are in relation to the distal end portion of the third hole portion 14 c of the waterproof connector 10 held by the holder portion 30. The relative proximity is gradually moved. When the main body 40 is further moved closer to the holder 30, the contact portion 92a enters the inside through the opening on the distal end side of the third hole portion 14c.

  And when the main-body part 40 is moved to the test | inspection position with respect to the holder part 30, the contact part 92a will contact the front-end | tip part of the terminal T of the waterproof plug crimping electric wire 18 inserted in the 3rd hole 14c. Up to this point, it is in a state of entering the tip side portion of the third hole portion 14c (see FIGS. 5 and 11).

  When the waterproof plug crimping electric wire 18 is satisfactorily inserted into all of the plurality of third holes 14c of the waterproof connector 10, the contact portions 92a of the plurality of terminal detection members 92 contact the tips of the terminals T. Then, all of the plurality of terminal detection members 92 are electrically closed. Thereby, the terminal insertion inspection circuit unit 94 is conducted, and the terminal insertion determination unit 96 determines that the insertion state of each of the plurality of waterproof plug crimped electric wires 18 in each third hole portion 14c is good.

  In addition, when any one of the plurality of third hole portions 14c is not properly inserted with the waterproof plug crimping electric wire 18, the terminal detection member 92 corresponding to the third hole portion 14c has the contact portion 92a as a terminal. It is not in contact with T and is in an electrically open state. Here, the case where the waterproof plug crimping electric wire 18 is not inserted well means that the waterproof plug crimping electric wire 18 is not inserted into the third hole 14c or completely (rear side) with respect to the third hole 14c. Up to) refers to the state that is not inserted. Thereby, the terminal insertion inspection circuit unit 94 becomes non-conductive as a whole, and the terminal insertion determination unit 96 determines that the insertion state of each of the plurality of waterproof plug crimped electric wires 18 in each third hole portion 14c is defective.

  As described above, the waterproof connector inspection apparatus 20 can perform the waterproof inspection and the terminal insertion inspection by moving the main body portion 40 from the set position to the inspection position with respect to the holder portion 30. The operator can know the quality of each inspection of the waterproof connector 10 to be inspected by checking the determination results of the waterproof determination unit 80 and the terminal insertion determination unit 96.

  After confirming the determination result, the operator operates the operation lever 24 to move the main body 40 away from the holder 30 and return it to the set position. At this time, the main body 40 is moved to the set position side by the urging force of the separation urging member 25.

  When the main body portion 40 is moved to the set position with respect to the holder portion 30, the operator takes out the waterproof connector 10 that has been inspected from the holder portion 30. When the waterproof connector 10 is determined to be good in both inspections, the worker uses it for the next process or the like, and when it is determined to be defective in either inspection or both inspections, it is removed or reassembled as a defective product. It is good to use for these processes.

  With the above operation, the inspection for one waterproof connector 10 is completed. Thereafter, the waterproof connector 10 to be inspected may be inspected in the same manner as described above.

  According to the waterproof connector inspection apparatus 20 configured as described above, the pusher member 60 is configured to be pushable so as to change the posture of the waterproof plug detection member 50 from the retracted posture to the approached posture. The waterproof plug detecting member 50 can be changed in posture from the retracted posture to the approaching posture when the waterproof plug P1 is not inserted into the first hole portion 14a or the second hole portion 14b. When the waterproof plug P1 is inserted into the two holes 14b, the protruding portion 52 is configured to abut against the waterproof plug P1 to prevent the posture change. Then, by determining whether or not the waterproof plug P1 is inserted into the first hole portion 14a and the second hole portion 14b according to the posture of the waterproof plug detection member 50 by the waterproof determination portion 80, the first hole portion 14a and the second hole portion 14a. It is possible to inspect whether or not the waterproof plug P1 is inserted into the hole 14b. That is, since the waterproof inspection is performed for each of the first hole portion 14a or the second hole portion 14b, the waterproof plug crimping electric wire 18 and the waterproof plug P1 are not inserted into some of the plurality of hole portions 14 in the inspection process. The waterproof connector 10 can also be inspected.

  Further, when the waterproof plug P1 is not inserted into the first hole portion 14a or the second hole portion 14b, the push member 60 is moved by the urging force of the urging member 66 for pushing. It is possible to push the waterproof plug detecting member 50 so as to change the posture from the leaving posture to the entering posture while being maintained at the advanced position. In addition, when the waterproof plug P1 is inserted into the first hole portion 14a or the second hole portion 14b, the pushing member 60 is pressed against the waterproof plug detecting member 50 maintained in the retracted position. The urging member 66 for movement is moved to the retracted position by the contraction operation, and the waterproof plug detecting member 50 is not pushed further. Thereby, since the waterproof plug detecting member 50 changes the posture more reliably depending on the presence or absence of the waterproof plug P1 with respect to the first hole 14a or the second hole 14b, the first hole 14a or the second hole more accurately. The presence or absence of the waterproof plug P1 with respect to 14b can be inspected. Further, the pushing member 60 is moved to the retracted position by absorbing the pushing force by the pushing biasing member 66 in a state where the waterproof plug detecting member 50 is maintained in the retracted position. Therefore, it is possible to suppress an excessive load.

  Moreover, the switch part 72 from which the electrical connection state in an on-off state differs, respectively can be arrange | positioned with respect to the 1st hole part 14a and the 2nd hole part 14b. That is, the first switch portion 72p disposed corresponding to the first hole portion 14a into which the waterproof plug P1 is inserted is electrically opened in the off state, and corresponds to the second hole portion 14b in which nothing is inserted. The second switch portion 72e arranged in this manner is set to be electrically closed in the off state. Therefore, depending on whether or not the waterproof plug P1 needs to be inserted, whether or not the waterproof plug P1 is inserted into the first hole portion 14a, or whether the waterproof plug P1 is inserted into the first hole portion 14b. It can be checked whether or not there is any.

  Further, since the plurality of switch portions 72 and the plurality of terminal detection members 92 are disposed in the main body portion 40, the wiring of the waterproof inspection circuit portion 70 and the terminal insertion inspection circuit portion 94 can be pulled out from the main body portion 40 collectively. Therefore, wiring can be easily made compact. Furthermore, since the plurality of switch parts 72 are arranged in a manner that they are exposed in the switch arrangement recess 49 of the main body part 40, there is an advantage that maintenance is easy.
