  As shown in FIG. 10, a pair of introduction grooves 45 that extend in the front-rear direction and open to the front edge of the peripheral wall portion 43 receive the first cam pins 67 on both side surfaces of the peripheral wall portion 43. It is made possible. And as shown in FIG. 9, the 2nd cam pin 46 is formed in the both sides | surfaces of the surrounding wall part 43 so that it may straddle the introduction groove 45, and it may protrude outward. The second cam pin 46 has a substantially portal shape when viewed from the front, and the first cam pin 67 can be fitted inside the second cam pin 46. When the first cam pin 67 enters the inside of the second cam pin 46, the cam groove 84 of the lever 80 is combined with the first cam pin 67 until the fitting of both the connectors 10 and 60 is completed. Is engaged. Accordingly, the female connector 60 and the moving plate 40 are moved together by the turning operation of the lever 80.

  In addition, positioning holes 47 through which the male terminal fittings 20 are inserted are aligned and formed in the plate body 42. As shown in detail in FIG. 11, the positioning hole 47 expands in a trumpet shape on the rear surface of the plate main body portion 42 to guide each male terminal fitting 20, while constricting on the front surface of the plate main body portion 42. The positioning of each male terminal fitting 20 is ensured by being opened in a state of being closed. The moving plate 40 is moved from the initial assembly position (hereinafter referred to as the initial position) where the plate main body 42 floats from the front surface of each male sub-connector 11 when the connectors 10 and 60 are fitted together. Is moved to a position (end position) at the time of completion of fitting that contacts the front surface of each male side sub-connector 11, but the male terminal fitting 20 is positioned in the positioning hole 47 regardless of the position of the movement path. In this way, the male terminal fitting 20 is reliably positioned. When the moving plate 40 is in the initial position, the front end portion of the male terminal fitting 20 protrudes from the front surface of the plate main body portion 42 to face the fitting surface side as shown in FIG. In this state, it is used for a continuity test (not shown). In addition, the front-end | tip position of each male terminal metal fitting 20 in the food | hood part 14 has aligned in the same position about the front-back direction.

  As shown in FIG. 8, a plurality of protective walls 41 are provided on the front surface of the plate body portion 42 (surface facing the female connector 60) so as to protrude forward. These protective walls 41 are provided corresponding to the recesses 66 formed on the front surface of the female connector 60 (the fitting surface with the male connector 10). That is, the protective wall 41 is disposed so as to partition each female sub-connector 61 when the connectors 10 and 60 are fitted together. In other words, the protective wall 41 is provided at a position that divides each male sub-connector 11.

  The protective wall 41 is connected to the plate body 42 in a form that rises substantially vertically from the front surface of the plate body 42. Further, both side edges of the protective wall 41 are connected to the peripheral wall portion 43, respectively. Specifically, the protective wall 41 is disposed between a pair of wall portions of the peripheral wall portion 43 where the second cam pin 46 is not provided. As a result, the protective wall 41 is disposed substantially in parallel with the pair of wall portions 43 </ b> A provided with the second cam pins 46 in the peripheral wall portion 43. Accordingly, the protective wall 41 is restricted from falling to the front surface of the plate main body portion 42 by connecting both side edges to both wall portions, and the plate main body portion 42 and the peripheral wall portion 43 themselves are also connected to the protective wall 41. The rigidity is increased by being integrally connected.

  At the front end of the protective wall 41, three notches 41A are formed by notching the center in the width direction and both sides in the width direction. The lock part 64A of the female connector 60 is arranged in the center cutout part 41A among the three cutout parts 41A when the connectors 10 and 60 are fitted together. That is, by providing the central cutout portion 41A, interference between the protective wall 41 and the lock portion 64A is avoided when the connectors 10 and 60 are fitted together.

  In addition, a pair of opposing walls 41B are provided so as to project to the side of the protective wall 41 in the central cutout 41A among the three cutouts 41A. As shown in FIG. 9, a through hole 42 </ b> A through which a release jig for releasing the lock portion 16 </ b> A is inserted is formed at a position corresponding to the space between the opposing walls 41 </ b> B in the plate main body portion 42. Accordingly, even when the moving plate 40 is housed in the hood portion 14, the locking between the lock portion 16A and the lock receiving portion 13A can be released by inserting the release jig through the through hole 42A. it can. At this time, since the release jig is inserted into the through hole 42A through the opposite walls 41B, the release jig is prevented from contacting the male terminal fitting 20, and deformation of the male terminal fitting 20 is prevented. be able to.

  As shown in FIG. 5, the protective wall 41 has a shape that becomes thinner toward the front. Further, the inner and outer edges (both edges in the thickness direction) of the front end of the protective wall 41 are notched and chamfered. As a result, when the connectors 10 and 60 are fitted together, the side walls of the protective wall 41 guide the protective wall 41 to enter the recess 66, and the protective wall 41 is fitted into the recess 66 of the female connector 60. In addition, the moving plate 40 can be moved in the positioning state in the hood portion 14.

  By the way, as shown in FIG. 4, the protruding amount of the protective wall 41 from the front surface of the plate body 42 is larger than the protruding amount of the front end portion of the male terminal fitting 20 protruding forward from the positioning hole 47. The reason for this is that even if the female connector 60 that has taken an incorrect posture from the front enters the hood portion 14 with the moving plate 40 accommodated in the initial position in the hood portion 14, the female connector 60. This is to prevent the peripheral edge of the fitting surface from abutting against the front end of the protective wall 41 and prevent the male terminal fitting 20 from being damaged.

  Now, as shown in FIG. 9, a pair of regulating protrusions (an example of the “locking portion” of the present invention) 48 protrude outwardly on the outer surfaces of both wall portions 43 </ b> A facing left and right in the peripheral wall portion 43. Is provided. Both regulating protrusions 48 are provided at positions corresponding to the central part of the opening edge of both wall parts 43A. The two restricting protrusions 48 have a pair of protrusions 48A disposed so as to be opposed to the outer surfaces of both wall parts 43A (projecting in an overhanging manner from both side surfaces of the peripheral wall part 43). Each protrudes in the opposite direction (vertical direction) along the outer surface of the wall 43A. Both protrusions 48 </ b> A are provided so as to protrude from both side walls constituting the introduction groove 45. For this reason, it is possible to form both protrusions 48 </ b> A using both side walls of the introduction groove 45. In addition, as shown in FIG. 10, both the control protrusions 48 have a form extending in the front-rear direction.

  On the other hand, as shown in FIG. 13, a pair of latches that correct the peripheral wall portion 43 to a normal posture by locking with both regulating projections 48 at positions corresponding to both regulating projections 48 in the hood portion 14. An edge portion (an example of the “locked portion” of the present invention) 21 is provided. Both locking edges 21 are provided so that the outer portions of both side edges constituting the upper and lower sides of the escape groove 19 are notched in a tapered shape. As shown in FIG. 14, both the locking edges 21 can be fitted with both restricting protrusions 48 in a groove shape. Thereby, even if both wall portions 43A are formed inwardly in the molding process, both the wall projections 48A are fitted into the regular posture by fitting both the restricting projections 48 and both the locking edges 21. Can be corrected. Therefore, when the connectors 10 and 60 are fitted together, it is possible to restrict the fitting operation of the connectors 10 and 60 from being disturbed by the fitting surface of the female connector 60 interfering with the opening edge of the peripheral wall portion 43. .

  Both the protrusions 48A are disposed so as to be asymmetric with respect to the axis C passing between the protrusions 48A. For this reason, when it is going to assemble the moving plate 40 with the wrong posture turned upside down with respect to the hood part 14, it is regulated that the moving plate 40 is installed in the hood part 14.

  The present embodiment is configured as described above, and its operation will be described subsequently. First, when the female connector 60 and the male connector 10 are fitted, the moving plate 40 is moved along the outer peripheral surface of the peripheral wall portion 43 along the inner peripheral surface of the hood portion 14 as shown in FIG. The lever 80 is held at the standby position while being held at the initial position. At this time, even when the peripheral wall portion 43 of the moving plate 40 is formed inwardly due to sink marks or the like at the time of molding, the protrusions 48A of the restricting protrusions 48 and the locking edges 21 are engaged. By assembling the moving plate 40 in the hood part 14 so as to be stopped, both wall parts 43A are pulled outward, and the peripheral wall part 43 is corrected to a normal posture. The same applies to the case in which both wall portions 43A are formed to protrude outward, and the moving plate 40 is corrected to the normal posture by assembling it in the hood portion 14 while bending both wall portions 43A inward. be able to.

  After the moving plate 40 is assembled to the hood portion 14 at the initial position, the female connector 60 is inserted into the hood portion 14 from the front. In this case, as shown in FIG. 5, when the female connector 60 takes the normal posture and enters the hood portion 14, that is, the female connector 60 has its front surface (fitting surface) along the height direction. When entering the hood portion 14 with its front face oriented in a direction substantially perpendicular to the longitudinal axis, the female connector 60 is fitted into the moving plate 40 and the side surface of the female connector 60 is surrounded by the peripheral wall portion 43. In addition, the front surface of the female connector 60 faces the front surface of the plate main body 42. In this state, as shown in FIG. 2, the first cam pin 67 enters the inlet of the cam groove 84 of the lever 80 and is fitted into the introduction groove 45, and the first cam pin 67 and the second cam pin 46 are joined together. The groove 84 can be engaged.

  Next, when the lever 80 is rotated to the fitting position side, the relative movement is performed so that the female connector 60 is pulled into the back side of the hood portion 14 by the cam action by the engagement of the second cam pin 46 and the cam groove 84. Then, both connectors 10 and 60 approach each other. At this time, the protective wall 41 of the plate body 42 is fitted into the recess 66 of the female connector 60, and the moving plate 40 moves in parallel with the female connector 60 to the back side of the hood portion 14. While the moving plate 40 moves, each male terminal fitting 20 remains in the correct position while penetrating the positioning hole 47, and enters the female terminal fitting 70 sequentially from the tip end side thereof. Increase the mating depth. When the moving plate 40 reaches the end position and the lever 80 reaches the fitting position, as shown in FIG. 3, both the connectors 10 and 60 are properly fitted, and the male terminal fitting 20 is properly fitted to the female terminal fitting 70. The two terminal fittings 20 and 70 are connected so as to be conductive by fitting at a depth.

  As described above, according to the present embodiment, the following effects are obtained. The moving plate 40 can be corrected to a normal posture by locking both the protrusions 48 </ b> A and the both locking edges 21. Moreover, since both the protrusions 48A are provided so as to protrude in opposite directions from both side walls constituting the introduction groove 45, both the protrusions 48A and both the locking edges 21 can be fitted in a groove shape. . In addition, since both the protrusions 48A are provided using both side walls of the introduction groove 45, the configuration of the restriction protrusion 48 can be simplified. In addition, since both the protrusions 48A are arranged so as to be asymmetric with respect to the axis C, erroneous assembly of the moving plate 40 can be restricted.
