A locking projection 35 that locks in the direction in which the terminal 12 and the terminal fitting 30 are pulled out is formed by knocking out. A stabilizer 36 for preventing reverse insertion of a terminal is bent in the standing direction (the stacking direction of the housing 10) on one side (left side as viewed from the front) of the rear end of the upper wall of the main body 31.

  The lid member 50 is formed in a substantially square plate shape with a synthetic resin material, and as shown in FIG. 2, the upper surface is a flat flat surface, and the locking means for the uppermost housing 10 is provided at the four corners of the lower surface. Is provided. The locking means includes a pair of left and right boss portions 61 disposed at both ends of the rear portion of the lid member 50 and a pair of left and right elastic locking pieces 71 disposed at both ends of the front portion of the lid member 50. Further, a retainer portion 81 for double-locking the terminal fitting 30 together with the lance 11 is provided at a substantially central portion in the front-rear direction of the lower surface of the lid member 50. Since the lower surface structure of the lid member 50 is substantially the same as the lower surface structure of the housing 10, the locking means and the retainer portion 81 will be described in detail later together with the structural description of the housing 10.

  In the illustrated case, the housing 10 includes an upper housing 10 and a lower housing 10. Both housings 10 have the same shape and are used interchangeably without being distinguished between a lower stage and an upper stage. Specifically, the housing 10 has a substantially rectangular shape in plan view with a synthetic resin material, and a plurality of terminal accommodating chambers 13 that can accommodate the terminal fittings 30 are provided in a row in the width direction (left-right direction). Yes.

  The terminal accommodating chamber 13 has a configuration in which persons adjacent in the width direction are partitioned by a partition wall 14 erected on the substrate 21 of the housing 10, extends in the front-rear direction, and opens on both front and rear surfaces of the housing 10. It has become. The front opening of the terminal accommodating chamber 13 is a tab insertion opening 13A having a narrowed opening to attract the tab of the mating terminal fitting from the front, and the rear opening of the terminal accommodating chamber 13 is a terminal into which the terminal fitting 30 can be inserted from the rear. It is set as the insertion port 13B. The housing 10 is provided with an opening 18 that communicates with the terminal insertion port 13B by notching the upper wall of the wall surrounding the four sides of the terminal accommodating chamber 13 into a predetermined shape.

  As shown in FIG. 3, the opening 18 is located at a substantially central portion in the front-rear direction of the housing 10 and communicates with a locking hole 15 that allows the retainer portion 81 to be inserted, and a rear end side of the locking hole 15. Then, the relief hole 16 of the stabilizer 36 that extends rearward and opens on the rear surface of the housing 10 and the mounting hole 17 of the stabilizer 36 that communicates with one side of the front end of the locking hole 15 and extends forward. Among these, the hole edge that continues from the locking hole 15 to the relief hole 16 of the stabilizer 36 is edged by the edge of the stopper wall 19.

  The stopper wall 19 is disposed so as to cover the upper part of the terminal accommodating chamber 13 in a bowl shape, and protrudes from the upper end of one partition 14 toward the upper end of the other partition 14 of the opposing partition walls 14. The shape of the cross section L is made with one partition wall 14. The stopper wall 19 extends from the terminal insertion port 13 </ b> B to the middle part in the front-rear direction of the terminal accommodating chamber 13, specifically, the rear end of the locking hole 15. The above-described escape hole 16 is retained between the side edge of the stopper wall 19 and the other partition wall 14. And the protrusion dimension of the stopper wall 19 is set small, and the width dimension of the escape hole 16 becomes large correspondingly, and the stabilizer 36 can pass through the escape hole 16 in the loosely inserted state. When the terminal fitting 30 is inserted into the terminal accommodating chamber 13 in a normal insertion posture, the stabilizer 36 enters the escape hole 16, and the main body 31 is disposed between the stopper wall 19 and the substrate 21 in the vertical direction (of the housing 10. The movement in the stacking direction) is entered in a restricted state. Note that the upper end of the stabilizer 36 and the upper end of the partition wall 14 are aligned at substantially the same position in the terminal accommodating chamber 13, so that the lower surface of the upper housing 10 or the lower surface of the lid member 50 can come into contact with the upper end of the stabilizer 36. Arranged.

  A region in front of the opening 18 in the housing 10, that is, a front half of the upper wall of the terminal accommodating chamber 13, is configured as a region where the lance 11 can be locked. That is, a lance 11 is formed in an exposed state between a pair of slits 22 cut from the front surface of the housing 10 so as to be able to bend and deform in the vertical direction. The lance 11 protrudes forward from the upper end of the partition wall 14 while being connected to the position near the opening 18 in the front half of the upper wall, and protrudes forward from the lower surface of the terminal fitting 30. A locking projection 12 is provided that can enter the lance hole 34 and lock with the locking projection 35. Further, a release jig (not shown) for releasing the locked state with the terminal fitting 30 by bending the lance 11 in a direction to disengage from the terminal fitting 30 is inserted into the center portion of the front end of the lance 11. A guide groove 23 is formed in the front surface of the housing 10 so as to open.

  A pair of left and right boss receiving portions 66 are provided at both ends of the rear portion of the upper surface of the housing 10. The boss receiving portion 66 has a block shape and is also integrally joined to the outer surface of the rear end of the partition wall 14 located at both ends in the width direction. The boss receiving portion 66 is provided with a bottomed receiving hole 67 that opens to the upper surface, and the boss portion 61 can enter the receiving hole 67 from above. The receiving hole 67 is substantially elliptical in plan view, and as shown in FIG. 9, is composed of a main hole 67A extending in the vertical direction and a sub hole 67B extending rearward from the bottom surface of the hole and opening on the rear surface of the housing 10. The boss portion 61 is inserted into the main hole 67A, and the locking projection 62 of the boss portion 61 is locked in the hooked state at the hole edge of the sub hole 67B.

  The housing 10 is provided with a pair of left and right receiving portions 77 integrally with the front outer surface of the partition wall 14 located at both ends in the width direction. The receiving portion 77 is formed by cutting out the upper outer surface of the partition wall 14 in a tapered shape and cutting the lower outer surface of the partition wall 14 in a U-shaped cross section, thereby forming a cross-section arrowhead and continuing in the front-rear direction. The front end (upper part) of the receiving part 77 is a receiving claw 78 having a tapered surface 78A on the outer side, and the locking claw 72 of the elastic locking piece 71 can be elastically locked to the lower surface of the receiving claw 78. . Further, a recess 29 for allowing the tip of the elastic locking piece 71 to escape is formed in the upper surface of the substrate 21 of the housing 10 around the base of the receiving portion 77.

  On the other hand, a pair of left and right boss portions 61 project from the rear ends of the lower surface of the housing 10 (including the lower surface of the lid member 50; the same applies hereinafter) at positions that are substantially coaxial with the boss receiving portion 66 and are back to back. . The boss portion 61 is provided with a cut 63 in the width direction from the lower surface to the base thereof, and is divided into a base portion 64 located on the front side and a flexure portion 65 located on the rear side across the cut portion 63. The bent portion 65 has a narrower front-rear width than the base portion 64 and has a structure in which the bent portion 65 is easily bent and deformed. A locking projection 62 that can be elastically locked to the hole edge of the receiving hole 67 (sub-hole 67B) is provided on the lower rear surface of the bending portion 65. The boss portion 61 is allowed to pass through the receiving hole 67 when the locking projection 62 is slid on the hole surface of the hole 67 while being inserted into the receiving hole 67, and the bending portion 65 is bent and deformed inward. When it is normally inserted into the hole 67 (main hole 67A), the bending portion 65 is elastically restored, and the locking protrusion 62 enters and locks into the sub-hole 67B so that it can be tightly fitted into the receiving hole 67 (main hole 67A). Is done. Thereby, it is possible to prevent the two housings 10 adjacent in the vertical direction from being displaced in the plate surface direction.

  Further, as shown in FIG. 5, on the lower surface of the housing 10, there is a retainer portion 81 arranged in a horizontal row at a position substantially corresponding to the center of the front and rear direction of the housing 10 and corresponding to each terminal accommodating chamber 13. Projected. The retainer portion 81 has a substantially square block shape, and as shown in FIG. 8, the retainer portion 81 is engaged with the rear end jaw portion 37 of the main body portion 31 of the terminal fitting 30 after passing through the locking hole 15. In addition, the terminal fitting 30 is locked only to the terminal fitting 30 in the normal insertion state, so that the presence or absence of the half-insertion state of the terminal fitting 30 can be detected.

  Further, a pair of left and right elastic locking pieces 71 protrude from both ends of the front portion of the lower surface of the housing 10 so as to be back to back with the receiving portion 77. Both elastic locking pieces 71 are arranged at a position slightly offset inward from the front and rear shafts passing through the boss part 61 arranged behind them, and can be bent and deformed inward and outward (in the width direction). A locking claw 72 that can be elastically locked to the receiving claw 78 of the receiving portion 77 is formed at the lower end of the elastic locking piece 71 so as to protrude inward. The elastic locking piece 71 is expanded and deformed outward when the locking claw 72 is in sliding contact with the taper surface 78A of the receiving claw 78 in the process of being stacked on the mating housing 10, but is elastically restored when it is properly stacked. Thus, the locking claw 72 is elastically locked to the receiving claw 78. Thereby, both the housings 10 adjacent in the vertical direction can be kept in a laminated state.

  Next, the operation of this embodiment will be described. First, as shown in FIGS. 12 and 13, the terminal fitting 30 is inserted into the terminal accommodating chamber 13 of the housing 10 from the rear. When the terminal fitting 30 is in the normal insertion posture during the insertion process, the insertion operation of the terminal fitting 30 is permitted by the stabilizer 36 passing through the escape hole 16 as shown in FIG. Thereafter, when the terminal fitting 30 is inserted into the terminal accommodating chamber 13 at a normal depth, the terminal fitting 30 is primarily locked by the lance 11 in a retaining state. On the other hand, if the terminal fitting 30 is in an upside down orientation, the front half of the main body 31 is inserted into the terminal accommodating chamber 13 as shown in FIG. By restricting the vertical movement, the stabilizer 36 abuts around the opening edge of the terminal insertion port 13B, specifically, the rear end edge of the substrate 21 facing the stopper wall 19, and the insertion operation of the terminal fitting 30 is restricted. The

  As shown in FIG. 4, when all the terminal fittings 30 are inserted into the corresponding terminal accommodating chambers 13 at a normal depth, the upper housing 10 is subsequently overlapped with the lower housing 10. Then, the boss portion 61 of the upper housing 10 is concavo-convexly fitted to the boss receiving portion 66 of the lower housing 10 in a positioned state, and the elastic locking piece 71 of the upper housing 10 is attached to the receiving portion 77 of the lower housing 10. The retainer portion 81 of the upper housing 10 is secondarily locked to the terminal fitting 30 in a retaining state, and the two housings 10 are united in a normal state. Since these engagement structures are formed almost simultaneously with the combined operation of the two housings 10, the workability is good.

  Next, in the same manner as described above, the lid member 50 is put on the upper housing 10 from above, and the opening 18 and the lance 11 of the upper housing 10 are covered with the lid member 50. As shown in FIG. A laminated structure is formed. The housing 10 may be laminated in three or more layers as necessary. Thereafter, the connector is fitted into the hood of the mating male connector while maintaining the stacked state of the housings 10.

  As described above, according to the present embodiment, the opening 18 leading to the terminal insertion port 13 </ b> B is opened on the upper wall of the terminal accommodating chamber 13, and the opening 18 is left leaving the escape hole 16 through which the stabilizer 36 can pass. Since the stopper wall 19 for preventing reverse insertion of the terminal to be closed is provided, the dimension of the housing 10 in the stacking direction is increased by the amount that the escape hole 16 penetrates vertically and the thickness of the groove bottom of the conventional escape groove is not added. Can be suppressed. In this case, since the stopper wall 19 extends long from the opening edge of the terminal insertion port 13B to the middle in the front-rear direction of the terminal accommodating chamber 13 at the upper end of the partition wall 14, the strength of the stopper wall 19 can be increased.

  Further, since the lance 11 which is deformable and deformable between the slits 22 placed on both sides is disposed in front of the opening 18 in the housing 10, there is no wall above the lance 11. Therefore, the increase in the dimension of the housing 10 in the stacking direction can be more efficiently suppressed.

In the first embodiment, an auxiliary locking structure different from the locking structure by the elastic locking piece 71 and the receiving portion 77 is formed by providing the locking projection 62 on the boss portion 61. However, if the locking structure by the elastic locking piece 71 and the receiving portion 77 is strong, it is not necessary to provide the locking projection 62 on the boss portion 61. That is, the positioning portion and the positioning receiving portion may simply be concavo-convexly fitted.

(Claim 3) In the housing, the receiving portion is provided on the surface on which the elastic locking piece is provided and the back-to-back surface, and the positioning receiving portion is provided on the surface on which the positioning portion is provided and the back-to-back surface.
