<Invention of Claim 1>
When the fitting assisting member moves in the parallel direction of the first housing with respect to the second housing, the respective engagement receiving portions are sequentially engaged with the engagement portions, whereby each first housing is different from the second housing in time. Therefore, the fitting force is reduced as compared with the case where the first housings are fitted together. Moreover, since only a common engaging part is formed with respect to each engaging receiving part, compared with the case where an individual engaging part is formed with respect to each engaging receiving part, the fitting assist The structure of the member is simplified.
In addition, after the preceding first housing has finished its fitting operation, the succeeding first housing starts its fitting operation, so that the fitting timing of both first housings does not overlap, and the fitting force Is further reduced. Moreover, since a play area that is disengaged from the engagement receiving portion can be formed in the engagement portion, the degree of freedom in design is increased.
Furthermore, since the first housing is temporarily fixed at a position where the first housing can be engaged with the fitting auxiliary member by providing the temporary holding portion in the second housing, smoothness of the movement operation of the fitting auxiliary member is ensured. .

  A vertically long annular flange 45 is provided over the entire circumference from the front end of the outer surface of the housing body 41 and the rear end of the outer surface of the hood portion 42 (that is, the boundary portion between the housing body 41 and the hood portion 42). ing. A rubber grommet 46 having a boot shape that covers the housing main body 41 and the electric wire W1 drawn from the housing main body 41 and the outer peripheral edge of the flange 45 is covered from the rear (see FIG. 2). In addition, the front surface of the flange portion 45 can be elastically locked to the rim of the mounting hole 91 formed in the panel 90 at the substantially central portion in the height direction and on the left and right sides of the hood portion 42. A pair of lock portions 47 are provided. The lock portion 47 includes a lock main body 48 that extends straight forward from the front surface of the flange portion 45 and a lock claw 49 that protrudes outward from the distal end portion of the lock main body 48. The lock claw 49 can be brought into contact with the locked surface 94 at the lip of the mounting hole 91 in a retaining state.

  The mounting hole 91 of the panel 90 has a main hole 93 that opens in a vertically long rectangular shape with a size that can accommodate the second housing 40 together with the slider 70, and is cut out at substantially the center in the height direction of both side edges of the main hole 93. It consists of a pair of sub-holes 92 which are provided and form a rectangular shape into which the lock portion 47 can enter from the front. The above-described locked surface 94 is configured at the mouth edge portion of the sub-hole 92 on the back surface side of the panel 90.

  The outer surface on both sides of the hood portion 42 is a mounting surface 50 on which a cam plate 72 (described later) of the slider 70 is slidably mounted. The front end of the mounting surface 50 of the hood portion 42 is provided with a pair of front side overhang portions 51 that extend over the entire length in the height direction, and also extends over the entire length in the height direction near the rear end of the mounting surface 50. A pair of rear side overhang portions 52 are provided. The front projecting portion 51 has a vertically long plate shape that projects outward by the thickness of the cam plate 72 while constituting the front end opening edge of the hood portion 42. On the other hand, the rear projecting portion 52 has an outer projecting piece 53 disposed in parallel with the front projecting portion 51 with a projecting amount smaller than the plate thickness of the cam plate 72 and the rear end portion thereof toward the rear. It consists of a protruding rear-side protruding piece 54 and has a vertically long plate shape with a cross-sectional L shape as a whole. The front projecting portion 51 is slidable on the front end of the cam plate 72, and the rear projecting portion 52 is slidable on a groove surface of a guide groove 73 (described later) formed on the inner surface of the cam plate 72. ing. In addition, although the rear side overhang | projection part 52 exists in the position which overlaps with the lock part 47 about the front-back direction, it does not interfere with the lock part 47 bent and deformed.

  A pair of entry grooves 55 into which cam followers 21 (to be described later) of the first housing 10 can enter are extended in the front-rear direction on both side walls of each housing part 43 in the hood part 42 and at the opening edge of the front end of the hood part 42 An opening is formed. The entry groove 55 communicates with the mounting surface 50 and penetrates the front projecting portion 51 in the front-rear direction (plate thickness direction). In addition, a pair of guide ribs 56 that can guide the fitting operation of the first housing 10 are formed on the inner surfaces of the housing portions 43 in the hood portion 42 so as to extend in the front-rear direction. The guide ribs 56 in the upper housing part 43 are formed above the center in the height direction, and the guide ribs 56 in the lower housing part 43 are formed below the center in the height direction. Further, each housing portion 43 is provided with a misconnection preventing rib 57 for preventing the first housing 10 from being fitted in a state where the first housing 10 is reversed in the forward and reverse directions. The misbonding prevention rib 57 in the upper housing portion 43 is formed to rise to one side from the center in the width direction of the upper surface of the partition wall 44, and the misbonding prevention rib 57 in the lower housing portion 43 is the upper surface of the lower wall of the hood portion 42. Similarly, it is formed so as to rise closer to one side than the center in the width direction. Both the guide rib 56 and the erroneous connection preventing rib 57 are formed from the middle of the hood portion 42 in the front-rear direction to the back end.

  As shown in FIGS. 1 and 9 to 11, the first housing 10 has a rectangular block shape as a whole, and a plurality of cavities 11 are arranged in the front and rear in a plurality of rows in the width direction and in a height direction. It is formed through. Each cavity 11 accommodates a female terminal fitting (not shown) connected to the end of the electric wire W2 from the rear, and each female terminal as the first and second housings 10, 40 are properly fitted. The metal fitting is connected to the corresponding male terminal metal fitting. Among the cavities 11, large female terminal fittings can be inserted into both side cavity groups 12 positioned on both sides in the width direction, and small female terminal fittings are inserted in the intermediate cavity group 13 positioned in the middle in the width direction. Can be inserted. In the first housing 10, mounting holes 14 into which the retainer 30 can be mounted are formed so as to open on three surfaces, both side surfaces and a lower surface. A recess 15 is formed on the outer surface of the rear portion of the first housing 10 so as to drop one step from the outer surface of the front portion, and the opening of the mounting hole 14 faces the bottom surface of the recess 15. On both sides of the bottom surface of the recess 15, a temporary locking portion 16 and a main locking portion 17 are provided side by side in the height direction. The mounting hole 14 is formed with a depth communicating with each cavity 11, and includes a both-side mounting hole 18 corresponding to the both-side cavity group 12 and an intermediate mounting hole 19 corresponding to the intermediate cavity group 13. As shown in FIG. 11, the both side mounting holes 18 and the intermediate mounting holes 19 are formed in different positions in the front-rear direction, and the intermediate mounting holes 19 are configured to be positioned forward of the both side mounting holes 18. Has been. Due to the positional displacement structure of the mounting hole 14, even if the mounting hole 14 is opened in three directions, the strength of the first housing 10 does not need to be significantly reduced. In addition, a slit-shaped erroneous connection preventing groove 20 extending in the front-rear direction from the front end to one side end of the intermediate mounting hole 19 is provided on the lower surface of the first housing 10. If the first housing 10 is in a proper insertion posture when the first housing 10 is fitted into each accommodating portion 43, the erroneous connection prevention rib 57 can be inserted into the erroneous connection prevention receiving groove 20.

  The retainer 30 is made of synthetic resin, and can be moved between a temporary locking position and a final locking position, and is held by the temporary locking portion 16 at the temporary locking position. The portion 17 is held and held. As shown in FIG. 1, the retainer 30 includes a substrate 31, a pair of side plates 32 that rise from both ends in the width direction, and a lattice-shaped holding portion 33 that protrudes from the upper surface of the substrate 31. . A retaining protrusion 34 is formed on the holding portion 33 at each position corresponding to each cavity 11. The holding portion 33 includes a both-side holding portion 35 that enters into the both-side mounting hole 18 and an intermediate holding portion 36 that enters into the intermediate mounting hole 19, and the intermediate holding portion 36 is positioned forward of the both-side holding portion 35. In addition, the height is higher than the both side holding portions 35.

  On both side surfaces of the first housing 10, a pair of cam followers 21 project from a substantially central portion in the width direction and a substantially central portion in the height direction. The cam follower 21 has a cylindrical shape, and enters the entrance groove 55 during the fitting process of the first and second housings 10 and 40 and engages with a cam groove 75 (described later) of the slider 70.

  Further, rib receiving grooves 22 that can receive the guide ribs 56 are provided on both side surfaces of the first housing 10 so as to extend in the front-rear direction. The front end of the rib receiving groove 22 opens at the front end of the first housing 10, and the rear end of the rib receiving groove 22 faces the front end of the side opening of the mounting hole 14. As shown in FIG. 9, the rib receiving groove 22 in the first housing 10 that can be fitted into the upper receiving portion 43 is installed above the cam follower 21 and is fitted into the lower receiving portion 43 as shown in FIG. 10. The rib receiving groove 22 in the possible first housing 10 is installed below the cam follower 21. As a result, only the first housing 10 corresponding to each of the upper and lower housing portions 43 can be fitted (see FIG. 5), and the first housing 10 to be fitted to the lower housing portion 43 is erroneous. Thus, the first housing 10 to be fitted into the upper housing part 43 or the upper housing part 43 is not accidentally fitted into the lower housing part 43. In the upper and lower first housings 10, the portions excluding the rib receiving grooves 22 have a common structure having the same shape.

  Next, the slider 70 will be described. As shown in FIGS. 1, 12, and 13, the slider 70 is configured in a gate shape by an operation plate 71 and a pair of cam plates 72 rising from both ends in the width direction. The hood part 42 of the second housing 40 can be mounted so as to straddle from below. The slider 70 is shallowly fitted to the hood portion 42 so that the operation plate 71 is positioned away from the lower wall of the hood portion 42 and the operation plate 71 is deeply fitted to the hood portion 42. It is possible to move in a straight line to a mounting completion position that can be brought into contact with the lower surface of the lower wall of the hood portion 42. The moving direction of the slider 70 is a direction perpendicular to the fitting direction of the first and second housings 10, 40, the parallel direction of the first housings 10, that is, the height direction of the second housing 40, The direction is set parallel to the plate surface direction of the panel 90. Note that the initial position in the present embodiment is an arbitrary position and is not set as a fixed position. Of course, the slider 70 may be retained at the initial position by providing the second housing 40 with temporary fixing means.

  The plate thickness dimension of the cam plate 72 is substantially equal to the plate thickness dimension of the operation plate 71, and is approximately equal to the extension amount of the front side extension portion 51. Near the rear end of the inner surface of each cam plate 72, a pair of guide grooves 73 are formed to be recessed over the entire length in the height direction. The guide groove 73 has a cross-sectional L shape that can fit the rear projecting portion 52, and a portion that receives the rear projecting piece 54 is a regulating piece 74 that projects forward. The rear overhanging portion 52 slides on the groove surface of the guide groove 73 to guide the moving operation of the slider 70, and the fitting force generated when the first and second housings 10 and 40 are fitted. Thus, the restricting piece 74 prevents the cam plate 72 from opening outward and deforming.

  Also, a pair of cams that can be sequentially engaged with the inner surface of each cam plate 72 in front of the guide groove 73 from the front side in the moving direction to the mounting completion position with respect to each cam follower 21 of each first housing 10. A groove 75 is formed as a recess. The cam groove 75 is a single common groove shared by the cam followers 21 of the first housings 10 in the cam plates 72. Specifically, as shown in FIG. 12, the cam groove 75 has a bottom like the guide groove 73 and has an introduction portion 76 that opens to the upper end of the cam plate 72 and extends short in the height direction, and the introduction portion 76. The cam main body 77 extends obliquely downward and rearward from the lower end with a predetermined gradient, and the play portion 78 extends straight from the lower end of the cam main body 77 downward in the height direction. The play portion 78 is configured to have a length that is at least twice that of the cam body portion 77. The cam main body 77 exhibits a cam action with the cam follower 21 so that the first and second housings 10 and 40 can be fitted with a low fitting force, and the play portion 78 is first fitted with a role. The cam follower 21 that has finished is entered and escaped. The groove width of the cam groove 75 is the same except for the entrance guiding portion 79, is substantially equal to the groove width of the entry groove 55, and is substantially equal to the diameter of the cam follower 21.

  Each cam plate 72 can enter the bending space of the lock portion 47 by being attached to the mounting surface 50 of the second housing 40. At the rear end portion of the outer surface of each cam plate 72, an interference portion 81 is provided along the height direction that slides in contact with the lock portion 47 in the process of moving the slider 70 from the initial position to the mounting completion position. ing. The interference part 81 is in a form that is flush with the general outer surface of each cam plate 72 positioned in front of the interference part 81 and does not have a specific structure. On the other hand, at the rear end portion of the outer surface of each cam plate 72, a lock portion 47 and a corresponding relief portion 82 are cut out and allowed while allowing the slider 70 to reach the mounting completion position. . The relief portion 82 is formed by cutting the cam plate 72 from the outside in the plate thickness direction, and is opened in a rectangular shape into which the lock portion 47 can be fitted. A substantially front half portion of the escape portion 82 is penetrated in the plate thickness direction through the guide groove 73, and a bottom portion of the substantially rear half portion of the escape portion 82 is partitioned by a regulating piece 74.

Next, the operation of this embodiment will be described.
First, the male terminal fitting is inserted into the second housing 40 and the female terminal fitting is inserted into the first housing 10. With respect to the first housing 10, the retainer 30 is mounted in the mounting hole 14, and the female terminal fitting is prevented from being detached by the retaining projection 34. Subsequently, the cam follower 21 of the first housing 10 is advanced from the front into the entry groove 55 of the hood portion 42 of the second housing 40, and the first housing 10 is inserted into each accommodating portion 43 of the hood portion 42. If the first housing 10 is in the normal posture, the erroneous connection prevention rib 57 enters the erroneous connection prevention receiving groove 20 in a fitted state, and the first housing 10 is smoothly inserted into each housing portion 43. On the other hand, if the first housing 10 is in a reverse / inverted posture, the erroneous connection preventing ribs 57 abut against the wall surface (front surface or rear surface) of the first housing 10 and are inserted into the receiving portions 43 of the first housing 10. Is regulated. Further, if the first housing 10 is to be inserted into the housing portion 43 different from the original, the rib receiving groove 22 and the guide rib 56 do not correspond to each other, so that the insertion operation of the first housing 10 into each housing portion 43 is performed as described above. Is regulated. Thereby, the erroneous fitting of each first housing 10 with respect to the accommodating portion 43 is reliably prevented.

  Then, when the first housing 10 is shallowly fitted in each housing portion 43, the first housing 10 is temporarily fixed by a temporary holding portion (not shown) in the housing portion 43 as shown in FIG. Any further insertion motion is restricted once. This temporary stop position corresponds to a position corresponding to the cam follower 21 so as to be able to enter the entrance of the cam groove 75, and in the illustrated case, is a substantially central portion in the front-rear direction of the entrance groove 55. The temporary holding portion is constituted by, for example, a small protrusion formed so as to be able to interfere with the cam follower 21 at the groove edge of the entry groove 55.

  From the above state, the slider 70 is pushed toward the mounting completion position while grasping the operation plate 71. Then, the cam follower 21 in the lower (first) first housing 10 positioned before the movement direction of the slider 70 enters the cam groove 75 of the slider 70, and the cam follower 21 moves from the introduction portion 76 as the slider 70 moves. Transition to the cam body 77. As the cam follower 21 moves along the entrance groove 55 and the cam main body 77, the lower (preceding) first housing 10 is drawn toward the inner side of the housing portion 43. When the cam follower 21 reaches the back end of the entry groove 55 and reaches the end of the cam main body 77, the lower (preceding) first housing 10 is fitted to the corresponding accommodating portion 43 at a normal depth, At the same time, the female terminal fitting is electrically connected to the male terminal fitting at a normal depth. At this time, the slider 70 is in a position that passes approximately half of the entire stroke.

  When the slider 70 is further pushed toward the mounting completion position, as shown in FIG. 3, the cam follower 21 in the upper housing (following) first housing 10 enters the cam groove 75. When the slider 70 reaches the mounting completion position in this manner, the upper (rear) first housing 10 is fitted to the corresponding accommodating portion 43 at a normal depth by the cam action of the cam follower 21 and the cam main body 77 as described above. The In the movement process of the upper (rear) first housing 10, the cam follower 21 in the lower (preceding) first housing 10 moves the play portion 78 relatively downward, while the first housing 10 itself is in a fixed position. To be kept in. In a state in which the upper (rear) first housing 10 is properly fitted, as shown in FIG. 2, the cam follower 21 in the upper (rear) first housing 10 is located at the start end of the play portion 78, and the lower The cam follower 21 in the (first) first housing 10 is located at the end of the play portion 78. Thereby, each 1st housing 10 will be sequentially fitted by the accommodating part 43 with a time difference.

  By the way, in the process of moving the slider 70 to the mounting completion position, as shown in FIGS. 3 and 6, the interference part 81 in the cam plate 72 of the slider 70 enters the bending space of the lock part 47, and the lock part 47. By being positioned so as to be slidable in contact with each other, the bending operation of the lock portion 47 is restricted. In this case, the lock part 47 is in contact with the interference part 81 and is in a deformed state. Thereafter, when the slider 70 reaches the mounting completion position, as shown in FIGS. 2 and 5, the relief portion 82 in the cam plate 72 of the slider 70 is positioned corresponding to the lock portion 47, and the bending space of the lock portion 47 is released. The bending operation of the lock part 47 is allowed. In this case, the lock portion 47 partially enters the escape portion 82 and is in a natural state.

  In a state where both housings 10 and 40 are fitted as described above, the second housing 40 is inserted together with the first housing 10 from the surface side into the mounting hole 91 of the panel 90. In the process of inserting the first and second housings 10 and 40 into the mounting holes 91, the lock claw 49 interferes with the hole edge of the sub-hole 92, and the lock portion 47 is bent and deformed into the escape portion 82 (inward). The When the second housing 40 is fitted into the attachment hole 91 at a normal depth, the lock claw 49 passes through the attachment hole 91 and the lock portion 47 is elastically restored, so that the lock claw 49 is covered with the attachment hole 91. The second housing 40 comes into contact with the locking surface 94 and is attached to the mounting hole 91 together with the first housing 10 in a retaining state. At this time, the rear end portion of the slider 70 partially enters the mounting hole 91. Further, at this time, the opening edge of the front end of the grommet 46 is in close contact with the surface of the panel 90, and the waterproofness in the second housing 40 is ensured.

  On the other hand, when the slider 70 is retained at a position before reaching the mounting completion position and at least the first housing 10 in the upper stage among the first housings 10 is in a semi-fitted state where it is not properly fitted, interference occurs. Since the bending operation of the lock portion 47 is restricted by the portion 81, the lock claw 49 cannot pass through the sub hole 92, and the lock portion 47 cannot be locked to the locked surface 94, and as a result, the second housing. The attachment to 40 panels 90 is regulated. Therefore, by confirming this state, it can be seen that the slider 70 has not reached the mounting completion position, and the first and second housings 10 and 40 are in a semi-fitted state. Even if the lock claw 49 passes through the sub-hole 92 due to the application of an excessive pushing force, the operation plate 71 located at the position lifted from the lower surface of the hood portion 42 of the second housing 40 remains on the surface of the panel 90. Since the insertion of the second housing 40 into the mounting hole 91 is restricted, the first and second housings 10 and 40 can be seen to be in a semi-fitted state.

  As described above, according to the present embodiment, the interference portion 81 restricts the bending operation of the lock portion 47, thereby preventing the second housing 40 from being attached to the panel 90. Therefore, the first and second housings Thus, it is possible to reliably know that the first and second housings 10 and 40 are left in the half-fitted state. As a result, it is assured that both housings 10 and 40 are in a properly fitted state.

  Further, since the moving direction of the slider 70 is set in a direction parallel to the plate surface direction of the panel 90, the slider 70 does not protrude greatly from the panel 90, and interference with peripheral components of the panel 90 can be avoided.

  Further, since the relief portion 82 is formed by cutting out the cam plate 72 in the direction of reducing the plate thickness, the slider 70 can be prevented from becoming large in the plate thickness direction, and the second housing 40 can be increased in size. While being avoidable, the enlargement of the mounting hole 91 into which the second housing 40 is fitted can be avoided.

  Further, when the slider 70 moves relative to the second housing 40 in the parallel direction of the first housing 10, the cam grooves 75 are sequentially engaged with the cam followers 21, whereby each first housing 10 is moved to the second housing 40. Therefore, the fitting force is reduced as a whole as compared with the case where the first housings 10 are fitted together. Further, since only the common cam groove 75 is formed for each cam follower 21, the number of cam grooves can be reduced compared to the case where individual cam grooves are formed for each cam follower 21. Thus, the configuration of the slider 70 is simplified.

  Furthermore, after the lower (leading) first housing 10 finishes the fitting operation, the upper (following) first housing 10 starts the fitting operation. Are not overlapped, and the fitting force is further reduced. Further, the preceding cam follower 21 can be easily released by setting the play portion 78.

  Furthermore, since the first housing 10 is temporarily fixed at a position where the first housing 10 can be engaged with the slider 70 by providing the temporary holding portion in the second housing 40, smoothness of the moving operation of the slider 70 is ensured.
