  By the way, in the laminated type connector as described above, it is necessary to inspect whether or not the terminal is completely inserted into each cavity. As an inspection method therefor, for example, the following method can be considered.

  In other words, if the terminal is incompletely inserted, the locking member interferes with the terminal, and the fact that a plurality of laminated connector housings cannot be combined in a completely laminated state is utilized. That is, a jig having a concave portion that has a shape in which a plurality of connector housings for stacking are combined in a stacked state is prepared. And the connector housing for lamination | stacking which inserted the terminal in the cavity is combined in a lamination | stacking state, and this is inserted in the said recessed part. If the connector in which the laminated connector housings are laminated is inserted into the recess, the terminal is completely inserted. If the connector cannot be inserted into the recess, the terminal is determined to be incompletely inserted. To do.

  However, in the above inspection method, even if the terminal is incompletely inserted, depending on the operator's force, the connector can be deformed so that the connector can be inserted into the recess. For this reason, even if the terminal is incompletely inserted, it may be determined that the terminal has been completely inserted by mistake. Also, as described above, the connector or the terminal may be deformed by forcibly inserting the connector into the recess.

  Then, an object of this invention is to enable it to test | inspect the insertion state of a terminal more correctly, suppressing a deformation | transformation of a connector and a terminal.

  In order to solve the above-mentioned problem, the terminal insertion state inspection device according to the first aspect includes a terminal insertion hole into which a terminal can be inserted, and the terminal locking portion is connected to the terminal insertion hole through a side opening of the terminal insertion hole.

It is configured to be switchable between a locked state to be locked and a unlocked state in which the locked state is released, and the detecting unit moves to the retracted position side from the advanced position to the locked state. A lock switching unit that is maintained and that can be switched to the unlocked state in a state where the detection unit has moved to the advanced position.

  The second aspect is a terminal insertion state inspection device according to the first aspect, wherein the terminal insertion state inspection device according to claim 1, wherein the lock switching part is formed by the holder part and the base holder part. A lock position that keeps the holder portion from moving from the housing set position to the inspection pass position and a non-contact state with the base holder portion, and the holder portion is moved from the housing set portion to the inspection pass position. And is supported so as to be movable between the unlocking position to be movable toward the position, the detection unit is maintained in the locked position in a state of moving to the retracted position from the advance position, and the detection unit is A first slider portion that can be moved to the unlocked position while being moved to the advanced position, and moved along the moving direction of the first slider portion by the first slider portion. The holder part is slidably contacted with the base holder part as the holder part is moved from the housing set position toward the inspection pass position, thereby moving the first through the interposing biasing member. The first slider portion is configured to be able to be pressed from the locked position toward the unlocked position, and the first slider portion is unlocked via the intervening biasing member in a state where the detecting portion is moved to the advanced position. And a second slider that maintains the first slider portion at the locked position by moving the intermediate biasing member while elastically deforming the intermediate biasing member in a state where the detecting portion is moved to the retracted position side. It has.

A terminal insertion state pass / fail detection unit that outputs the detection result is further provided.

  A terminal insertion state inspection device according to a fifth aspect is a terminal insertion state inspection device according to any one of the first to fourth aspects, wherein the holder portion is moved to the inspection pass position, A holder lock part for locking the holder part is further provided.

  According to the terminal insertion state inspection apparatus according to the first aspect, when the stacking connector housing in which the terminals are completely inserted into the terminal insertion holes is set in the holder part, the detection part can be moved to the advanced position. When the detection unit moves to the advanced position, the lock switching unit is switched to the unlocked state, and the holder unit can move from the housing set position toward the inspection pass position. Further, when the stacking connector housing in which the terminal is incompletely inserted into the terminal insertion hole is set in the holder portion, the state where the detection portion is in the retracted position side is maintained by contacting the terminal. As a result, the lock switching unit is maintained in the locked state, and the holder unit is locked so as not to move to the inspection pass position. For this reason, it can be more accurately inspected whether the terminal is in a completely inserted state or an incompletely inserted state depending on whether the holder part can be moved from the housing set position to the inspection pass position. At this time, the urging force by the detection unit urging unit relatively stably acts on the connector housing and the terminals for stacking, and it is difficult for excessive force such as human force to be applied. For this reason, a deformation | transformation of a connector and a terminal can be suppressed.

Thereby, a lock switching part will be in a lock release state, and can move a holder part to a test pass position. Further, in the state where the terminal is incompletely inserted, if the holder portion is moved from the housing set position toward the inspection pass position, the second slider portion moves while elastically deforming the intervening biasing member. One slider part is maintained in a locked position, and a holder part is locked so that it cannot move to an inspection pass position. For this reason, the portion that contacts the base holder portion to maintain the holder portion in the locked state and the portion that slides against the base holder to move the first slider portion to the unlocking position are The portion and the second slider portion can be provided separately. Thereby, the damage etc. of the 2nd slider part which are slidably contacted with a base holder part can be prevented effectively.

  According to the third aspect, when the connector housing for stacking is not set, the housing detection unit is located at the detection unit movement restriction position, so that the detection unit is maintained at the retracted position. Thereby, the holder part is maintained in the locked state, and erroneous inspection when the connector housing for stacking is not set can be prevented. And since the structure which controls the movement of a holder part using the said detection part is shared, simplification of a structure can also be aimed at.

  According to the 4th aspect, based on the detection result from a terminal insertion state pass / fail detection part, it can be notified whether terminal insertion is complete, or it can be useful for manufacture management.

  According to the fifth aspect, whether or not the holder portion can be locked by the holder lock portion can ensure the inspection.

  Hereinafter, the terminal insertion state inspection apparatus according to the embodiment will be described.

It is configured.

  The outer shape of the upper connector housing 12 for lamination is formed in a flat rectangular parallelepiped shape. In the upper connector housing 12 for lamination, a plurality of terminal insertion holes 12h (also called cavities) are formed in parallel so as to be partitioned by a partition wall. Each terminal insertion hole 12 h is formed in a hole shape longer than the terminal 11. On one end side of each terminal insertion hole 12h, there is formed a positioning portion that has an opening into which a mating terminal can be inserted and that can contact the tip of the connecting portion 11b to position the terminal 11. The other end of each terminal insertion hole 12h is formed in an opening shape into which the terminal 11 can be inserted. The state in which the terminal 11 is inserted into the terminal insertion hole 12h until the tip of the connection portion 11b contacts the positioning portion is a complete insertion state, and the state in which the terminal 11 is inserted in front is not satisfactory. Fully inserted. Further, the upper connector housing 12 for lamination is formed with a side opening 12ha located on each side (lower side in FIG. 1) of each terminal insertion hole 12h. The side opening 12ha is formed at a position closer to the crimping portion 11a than the connection portion 11b with respect to the completely inserted terminal 11, and at a position corresponding to the connection portion 11b with respect to the incompletely inserted terminal 11. ing. And the front-end | tip part of the terminal latching | locking part 15 mentioned later is comprised so that arrangement | positioning in the terminal insertion hole 12h is possible via side opening 12ha.

  The intermediate connector housing 14 for lamination has terminal insertion holes 14h and side openings 14ha having the same configuration as the terminal insertion holes 12h and the side openings 12ha in the upper connector housing 12 for lamination. In addition, terminal locking portions 15 are formed to protrude from the intermediate connector housing 14 for stacking at positions corresponding to the respective side openings of the upper connector housing 12 for stacking that are adjacent in the stacked state. . The upper connector housing 12 for stacking and the intermediate connector housing 14 for stacking are combined in a stacked manner so that the tip of the terminal locking portion 15 passes through the corresponding side opening 12ha and enters the terminal insertion hole 12h. It is arranged. In this state, the distal end portion of the terminal locking portion 15 comes into contact with the connection portion 11b of the terminal 11 completely inserted into the terminal insertion hole 12h from the crimping portion 11a, and positioning is performed with the terminal 11 fully inserted. It is configured.

  The bottom housing 16 is configured such that a plurality of terminal locking portions 17 having the same configuration as the terminal locking portions 15 are formed on a substantially square plate-like base portion 16a.

When the holder part 22 is above the inspection pass position (see FIGS. 5 and 7), the holder part 22 is slidably contacted with one side surface of the holder part 22 while the holder part 22 is in sliding contact. When the holder 22 is moved to the inspection pass position, the contact restricting portion 93 is moved to the holder restricting position by the urging force of the coil spring 98 and the tip of the contact restricting portion 93 is moved to the holder portion 22. Accordingly, the upward movement of the holder portion 22 from the inspection pass position is restricted. In this state, if the holder lock movable part 92 is moved to the holder non-restricted position against the urging force of the coil spring 98 by operating the operation part 94, the holder part 22 can be moved upward from the inspection pass position. become.

  FIG. 10 is a front view showing a main part of the detection unit 40, and FIGS. 11 and 12 are explanatory diagrams showing the operation of the detection unit 40 during inspection. As shown in FIGS. 3 to 7 and FIGS. 10 to 12, the detection unit 40 is disposed so as to be relatively movable with respect to the holder unit 22, and the upper connector for stacking held by the holder unit 22. The housing 12 is configured to be movable between a position (see FIG. 6) advanced through the side opening 12ha and a retracted position (see FIG. 5) retracted from the advanced position into the terminal insertion hole 12h.

  More specifically, the detection unit 40 includes a substantially plate-shaped detection main body 42 and a protrusion detection unit 44. The detection main body portion 42 is formed in an elongated plate shape, and is disposed in the detection portion guide hole 27 so that one side portion (here, one long side portion) is directed toward the housing set recess 24. Has been. The width dimension of the detection main body 42 has such a length dimension that the one side portion can be opposed to the whole of the plurality of side openings 12ha formed in the upper connector housing 12 for lamination. Further, the plurality of protrusion detection portions 44 are formed corresponding to the plurality of side openings 12ha formed in the upper connector housing 12 for lamination to be set in the housing set recess 24. Each protrusion detection part 44 has a base end part 44a that can be disposed in the side opening 12ha and a detection front end part 44b that further protrudes from the base end part 44a. In the state where the terminal 11 is completely inserted into the terminal insertion hole 12h, when the protrusion detection part 44 is moved toward the corresponding side opening 12ha, the detection tip part 44b is moved into the terminal 11 in the terminal insertion hole 12h. Of the connecting portion 11b is moved so far as to come into contact with the portion on the crimping portion 11a side and disposed at the advanced position (see FIG. 11). On the other hand, when the terminal 11 is incompletely inserted into the terminal insertion hole 12h, the connecting portion 11b of the terminal 11 is disposed at a position corresponding to the side opening 12ha. For this reason, when the protrusion detection part is moved toward the corresponding side opening 12ha, the detection tip part 44b comes into contact with the outer periphery of the connection part 11b and is prevented from moving to the advance position (FIG. 12). reference).

  In addition, the length dimension of the detection unit 40 in the moving direction of the detection unit 40 is such that the lower end of the detection unit 40 protrudes into the lock unit receiving recess 25 formed in the holder unit 22 in a state where the detection unit 40 is moved to the advance position. In the state in which the detection unit 40 is moved from the advanced position to the retracted position side, the lower end portion of the detection unit 40 is in the lock unit accommodating recess 25 while being accommodated in the detection unit guide hole 27 of the holder body 23 (see FIG. 10). (See particularly the state shown in FIG. 12). Thereby, according to the position of the detection part 40, the lock switching part 50 arrange | positioned in the lock | rock part accommodating recessed part 25 is switched between locking and unlocking. This point will be further described in detail in the description of the lock switching unit 50.

  A pair of detection unit guide rods 48 are provided on both sides of the lower end of the detection main body 42 of the detection unit 40 so as to extend downward. Each detection unit guide rod 48 penetrates the lock switching unit 50 and the holder bottom 29 in a loosely inserted state, extends below the holder unit 22, and is supported so as to be freely inserted into the bottom of the second divided body 34. . A flange portion (not shown) is formed at the lower end portion of the detection portion guide rod 48, and has a retaining shape with respect to the holder bottom portion 29. Thus, when the holder portion 22 is located at the housing set position, the detection portion 40 does not protrude into the housing set recess 24, and the upper connector housing 12 for stacking can be smoothly accommodated while avoiding interference with the detection portion 40. It can be inserted into the set recess 24. A coil spring 49 as an urging member is disposed around each detection unit guide rod 48. The coil spring 49 is interposed between the detection main body 42 and the upward bottom surface of the holder guide recess 35, and urges the detection unit 40 upward. Then, when the holder portion 22 is moved from the housing set position to the inspection pass position, the detection portion 40 is relatively moved from the advanced position or the advanced position to the retracted position according to the insertion state of the terminal 11 under the biasing force of the coil spring 49. It becomes a state.

  FIG. 13 is a perspective view illustrating the lock switching unit 50, and FIGS. 14 to 17 are explanatory diagrams illustrating the operation of the lock switching unit 50. As shown in FIGS. 4 to 6 and FIGS. 13 to 17, the lock switching unit 50 locks the holder unit 22 so that it cannot be moved from the housing set position to the inspection pass position (FIGS. 7, 16, and 17). 17) and the unlocked state in which the locked state is released (see FIGS. 6, 14 and 15), and the detection unit 40 is located on the side of the retracted position with respect to the advanced position. It is configured to be maintained in the locked state in a state where it is moved to, and to be switched to the unlocked state in a state where the detection unit 40 is moved to the advanced position.

  More specifically, the lock switching unit 50 includes a first slider unit 52, a second slider unit 56, and a coil spring 59 as an interposing biasing member.

  The first slider portion 52 has a first slider main body portion 53 and a movable lock portion 54. The first slider main body 53 is formed in a substantially block shape that is movable in the extending direction in the lock portion accommodating recess 25 of the holder portion 22. A guide protrusion 53 a that can be disposed in the lower relief recess 32 b is formed at the end of the first divided body 32 in the first slider main body 53. A guide surface 53b is formed at the tip of the guide protrusion 53a. The guide surface 53b is inclined downward toward the tip. When the first slider portion 52 moves upward together with the holder portion 22 in a state where the guide protruding portion 53a is disposed in the lower escape recess 32b, the guide surface 53b is placed on the inner peripheral surface of the lower escape recess 32b. The first slider portion 52 is configured to be pushed and moved into the lock portion accommodating recess 25 in sliding contact.

  In addition, a restriction recess 53 c is formed in a portion of the main surface above the first slider body 53 that can face the detection unit 40 in the detection unit guide hole 27. Here, the restriction recess 53 c is formed in a groove shape having a predetermined width and a predetermined depth extending over the entire width direction of the first slider main body 53. Then, in a state where the lower end portion of the detection unit 40 is disposed so as to protrude into the lock unit receiving recess 25, the lower end portion of the detection unit 40 is disposed in the restriction recess 53c and abuts on both side portions thereof. It becomes a possible state, and it is set as the structure by which the movement of the 1st slider part 52 is controlled by this (refer FIG.16 and FIG.17).

  Further, the movable lock portion 54 is formed in a long pin shape, and is attached and fixed so as to extend outward from a portion of the first slider main body 53 on the third divided body 38 side. Here, the distal end portion of the movable lock portion 54 is formed in a head portion 54a having a larger diameter than the front side portion thereof. The movable lock portion 54 moves along with the first slider main body portion 53 in the lock portion receiving recess 25 along the extending direction thereof, and in the state where the movable lock portion 54 moves to the third divided body 38 side, The portion 54a abuts against the receiving convex portion 39 from above to restrict the holder portion 22 from moving from the housing set position to the inspection pass position, and the movable lock portion 54 moves away from the third divided body 38. In this state, the contact between the movable lock portion 54 and the receiving convex portion 39 is avoided, and the holder portion 22 becomes movable from the housing set position to the inspection pass position.

  As described above, the first slider portion 52 makes the movable lock portion 54 contact the receiving convex portion 39 so that the holder portion 22 cannot be moved from the housing set position to the inspection pass position (FIGS. 16 and 17). And a lock release position (see FIGS. 14 and 15) that allows the holder portion 22 to move from the housing set position toward the inspection pass position by bringing the movable lock portion 54 into a non-contact state with the receiving convex portion 39. ) Is supported so as to be movable between. In addition, when the detection unit 40 moves to the retracted position side and the lower end of the detection unit 40 protrudes into the lock receiving recess 25, the lower end of the detection unit 40 contacts the inner peripheral surface of the restriction recess 53c. When the first slider portion 52 is maintained in the locked position and the lower end portion of the detection portion 40 does not protrude into the lock portion receiving recess 25 due to the detection portion 40 moving to the advanced position, the detection is performed. The movement restriction by the portion 40 is released, and the first slider portion 52 can be moved to the unlock position.

  The second slider portion 56 is formed in a shape that can move within the lock portion receiving recess 25 and is supported by the first slider portion 52 so as to be movable along the moving direction of the first slider portion 52. ing. Here, the movable lock portion 54 is inserted into an insertion hole 56 h formed in the intermediate portion in the width direction of the second slider portion 56, and the grooves and protrusions on both sides of the second slider portion 56 and the first slider portion 52. The second slider portion 56 is movably supported by the first slider portion 52 by the fitting guide structure of the portions. The head 54 a of the movable lock portion 54 prevents the movable lock portion 54 from coming off from the second slider portion 56.

  In addition, a pair of guide protrusions 57 that can be disposed in the upper escape recess 38 b are formed on the second divided portion 38 side of the second slider portion 56. The pair of guide protrusions 57 protrudes at positions where the movable lock part 54 is sandwiched. A guide slidable contact surface 57a that is inclined upward toward the outer side on the upper escape recess 38b side is formed at the tip of each guide protrusion 57. When the holder portion 22 is in the housing set position, each guide protrusion 57 is disposed in the upper relief recess 38b. When the holder portion 22 is moved downward in this state, the guide sliding contact surface 57a is configured to slide in contact with the lower portion of the upper clearance recess 38b and push the second slider portion 56 into the lock portion receiving recess 25.

  The coil spring 59 is attached to the movable lock portion 54 so as to be interposed between the first slider body portion 53 and the second slider portion 56 in a compression state. Then, as the holder portion 22 is moved from the housing set position toward the inspection pass position, the second slider portion 56 is pushed and moved into the lock portion receiving recess 25 as described above. The two slider portions 56 press the first slider portion 52 from the lock position toward the unlock position via the coil spring 59. At this time, in the state where the first slider portion 52 is restricted to the locked position as described above, only the second slider portion 56 is mainly maintained while maintaining the first slider portion 52 at the locked position by compressing and deforming the coil spring 59. Becomes movable. In a state where the first slider portion 52 can move to the unlocking position, the second slider portion 56 presses the first slider portion 52 via the coil spring 59 and moves it to the unlocking position.

  An inspection method using the terminal insertion state inspection apparatus 20 configured as described above will be described.

  First, in the initial state, as shown in FIG. 5, the holder portion 22 is in a state of being disposed at the upper housing set position. In this state, the detection unit 40 does not protrude into the housing set recess 24. Further, the first slider 52 of the lock switching unit 50 is located at the lock position. Moreover, the holder lock movable part of the holder lock part 90 is in a state located at the holder non-regulating position. Further, in this initial state, when the upper connector housing 12 for stacking is not set, the housing detection unit 70 is in a state of being positioned at the detection unit movement restriction position (see FIG. 8). 1 The slider part 52 is set to the locked position, and even if the holder part 22 is pushed down, it cannot be lowered until it reaches the inspection pass position.

  In this state, the operator inserts the upper connector housing 12 for stacking with the terminals 11 inserted into the respective terminal insertion holes 12h into the housing set recesses 24 (see FIG. 3). Then, the tip end of the upper connector housing 12 for laminating comes into sliding contact with the sliding contact surface 76a of the upper connector housing 12 for laminating, and the housing detection unit 70 moves to the detection unit movement allowable position side against the elastic force of the coil spring 78. . Thereby, the detection part 40 will be in the state which can protrude in the housing set recessed part 24. FIG.

  In this state, the operator pushes the holder portion 22 downward, for example, to apply a force from the housing set position to the inspection pass position on the holder portion 22. Then, in the middle of the movement of the holder part 22, the detection part 40 tends to project and move toward the housing set recess 24 relative to the holder part 22. At this time, if all the terminals 11 are in the completely inserted state, each protrusion detecting portion 44 of the detecting portion 40 is in a state of having advanced into the terminal insertion hole 12h through the side opening 12ha of the upper connector housing 12 for lamination. The detection unit 40 is moved relative to the holder unit 22 to the advance position (see FIG. 11). Then, the lower end part of the detection part 40 will be in the state which does not protrude in the lock part accommodation recessed part 25 (refer FIG. 6), and the 1st slider part 52 of the lock switch part 50 will be movable from a lock position to a lock release position. .

  Thereafter, when the holder portion 22 is further pushed toward the inspection pass position, the guide sliding contact surfaces 57a of the pair of guide projections 57 of the second slider portion 56 are slidably contacted with the lower portion of the upper escape recess 38b. The second slider portion 56 moves toward the lock portion receiving recess 25, and the first slider portion 52 moves to the lock release position so as to be pushed by the second slider portion 56 (see FIGS. 14 and 15). ).

  When the holder portion 22 reaches the inspection pass position, one side portion of the holder portion 22 presses the operation portion 82 of the micro switch 80 (see FIG. 6), and a notification that the inspection has passed is made. Further, when the holder part 22 reaches the inspection pass position, the holder lock movable part 92 is moved to the holder restricting position by the biasing force of the coil spring 98, and the holder part 22 is maintained in a state of being located at the inspection pass position (FIG. 6). reference).

  After completion of the inspection, when the operator moves the holder lock movable portion 92 to the holder non-regulating position, the holder portion 22 moves from the inspection pass position toward the housing set position by the biasing force of the coil spring 22S. At this time, the guide surface 53b of the guide projecting portion 53a of the first slider portion 52 is in sliding contact with the upper portion of the inner peripheral surface of the downward escape recess 32b, and the first slider portion 52 moves toward the lock position, so that Return. Thereafter, when the upper connector housing 12 for lamination is removed, the upper connector housing 12 for lamination that has passed the inspection as having a fully inserted terminal is obtained.

  On the other hand, when one of the terminals 11 is incompletely inserted, each protrusion detection part 44 of the detection part 40 cannot advance into the terminal insertion hole 12h through the side opening 12ha of the upper connector housing 12 for lamination. The state, that is, the state located on the retracted position side from the advance position (see FIG. 12). Then, the lower end part of the detection part 40 will be in the state which protruded in the lock | rock part accommodation recessed part 25 (refer FIG.7, FIG.12, FIG.16 and FIG.17), and the 1st slider part 52 of the lock switch part 50 locks from a lock position. Cannot move to the release position.

  For this reason, the guide sliding contact surface 57a is in sliding contact with the lower portion of the upper relief recess 38b while the first slider 52 is maintained in the locked position while the holder 22 is moving from the housing set position to the inspection pass position. Then, after the second slider portion 56 has moved slightly into the lock portion receiving recess 25, the movable lock portion 54 comes into contact with the receiving convex portion 39, and the holder portion 22 cannot be lowered any further. That is, the holder part 22 will be unable to move until it reaches the inspection pass position from the housing set position.

  In this way, it is possible to inspect whether or not the terminal 11 is completely inserted in a situation where the holder part 22 cannot be moved to the inspection pass position.

  According to the terminal insertion state inspection device 20 configured as described above, when the upper connector housing 12 for lamination in which the terminals 11 are completely inserted into the terminal insertion holes 12h is set in the holder portion 22, the detection portion 40 can move to the advanced position. become. When the detection unit 40 moves to the advanced position, the lock switching unit 50 is switched to the unlocked state, and the holder unit 22 can move from the housing set position toward the inspection pass position. Further, when the upper connector housing 12 for lamination in which the terminal 11 is incompletely inserted is set in the holder portion 22, the detection portion 40 is in contact with the terminal 11 and is maintained in a state of being located closer to the retracted position than the advanced position. Thereby, the lock switching part 50 is maintained in the locked state, and the holder part 22 cannot be moved until it reaches the inspection pass position. Therefore, whether or not the terminal 11 is in a completely inserted state or an incompletely inserted state can be more accurately inspected depending on whether or not the holder portion 22 can be moved until reaching the inspection pass position. .

  Further, when the inspection is performed as described above, the force acting on the terminal 11 and the upper connector housing 12 for lamination is basically that the detection unit 40 moves forward into the terminal insertion hole 12h by the biasing force of the coil spring 49. In addition, it is difficult to apply excessive power due to human power. Therefore, the deformation | transformation with respect to the upper connector housing 12 for lamination | stacking and the terminal 11 can be suppressed.

  In addition, when the terminal 11 is completely inserted, if the holder portion 22 is moved from the housing set position toward the inspection pass position, the guide sliding contact surface 57a of the second slider portion 56 is below the upper escape recess 38b. The second slider portion 56 and the first slider portion 52 are moved in slidable contact with the side portion to be in the unlocked state. On the other hand, when the terminal 11 is incompletely inserted, the second slider portion 56 moves while elastically deforming the coil spring 59 while maintaining the first slider portion 52 in the locked position, and eventually the movable lock portion 54 of the first slider portion 52. Comes into contact with the receiving convex part 39 and the movement of the holder part 22 to the inspection pass position is restricted. For this reason, the movable lock portion 54 which is a portion to be brought into contact with the base holder portion 30 in order to restrict the movement of the holder portion 22, and the guide sliding contact which is a portion for moving the first slider portion 52 to the unlock position. The surface 57a can be a separate part. The portion that receives the force for restricting the movement of the holder portion 22 is subject to excessive force due to human power or the like. By doing so, an excessive force is applied to the guide sliding contact surface 57a. It becomes difficult to effectively prevent the guide sliding contact surface 57a from being damaged, and a smooth inspection operation can be expected. However, a configuration in which these forces act on the same portion may be used.

  Further, in a state in which the upper connector housing 12 for stacking is not set, the housing detection unit 70 is located at the detection unit movement restriction position, so that the detection unit is maintained at the retracted position. Thereby, the holder part 22 is maintained in the locked state, and erroneous inspection when the upper connector housing 12 for stacking is not set can be prevented. In addition, since the configuration related to the detection unit 40 and the lock switching unit 50 is shared, the configuration can be simplified.

  Moreover, when the holder part 22 reaches the inspection pass position, the holder part 22 by the holder lock part 90 is locked. For this reason, it can be known whether the holder part 22 was able to move to a test | inspection pass position by whether the holder part 22 is locked by the holder lock part 90, and can ensure the test | inspection.
