[0025]
As shown in FIGS. 11 and 12, the sliding plates 71 of the slider 70 are provided with temporary locking pieces at positions corresponding to the substantially central portion of the cam groove 74 in the length direction and close to the rear edge. 90 is formed. The temporary lock piece 90 faces the base end side of the sliding plate 71 and protrudes in a cantilever manner so that it can be bent and deformed. A protrusion 91 is formed on the outer surface side of the protrusion end. In addition, the back side (left side in FIG. 12) of the protrusion 91 is a tapered surface.
[0026]
On the other hand, as shown in FIG. 1, the cover portion 23 in the female housing 20 is formed with a locking groove 93 at the center in the length direction at a position along the rear edge. In this locking groove 93, the protrusion 91 of the temporary lock piece 90 can be freely fitted and the surface side is closed at both ends in the length direction.
The slider 70 is inserted from, for example, the insertion passage 24 of the female housing 20 from the left side of FIG. 1, and the protrusion 91 of the temporary lock piece 90 is locked to the left edge of the locking groove 93 in the same figure. 70 is held in a retracted position in a retracted position. In this retracted position, the inlet 75 of the cam groove 74 is aligned with the through-hole 79 of the female housing 20, as shown in FIG.
[0027]
On the other hand, the position where the connecting plate 72 is pushed in until it hits the left side surface of the female housing 20 is the forward movement position. In this forward movement position, as shown in FIG. It fits in 89 and is locked.
Even when the slider 70 is mounted from the right side surface side of the female housing 20, the same effect as described above is exhibited, so that the duplicated description is omitted. In other words, depending on the position of the connector, it is possible to select the right or left direction in which the slider 70 can be easily inserted.
[0028]
The present embodiment has the above-described structure, and an example of the assembly procedure will be described next.
On the female housing 20 side, after the packing 95 is mounted on the outer periphery of the base portion of the tower portion 21, the front stop portion 21A is integrally coupled (see FIG. 16). In addition, the packing 95 is prevented from coming off.
Next, the retainer 40 is inserted into the retainer insertion port 50. During the insertion, guide grooves 52 and 52A provided on both front and rear surfaces of the arm portion 42 of the retainer 40 relatively enter the corresponding ribs 57 and 57A on the wall surface of the retainer insertion port 50, and the locking piece. A portion extending from 54 to the overhang edge 53 enters the insertion groove 58, and the cantilever arm 46 enters the insertion groove 51 on the back surface.
[0029]
When the retainer 40 is pushed close to the end, the protrusion 59 of the insertion groove 58 is elastically fitted into the temporary locking recess 55A on the back side of the locking piece 54, so that the retainer 40 is temporarily mounted as shown in FIG. It is held in the locked position. In this temporary locking position, the locking protrusions 45 and 47 are retracted to the front side of the corresponding cavities 32S and 32L. In particular, on the small female terminal locking portion 41S side, each arm portion 42 is concavo-convexly fitted over almost the entire length thereof, such as the guide grooves 52, 52A and the ribs 57, 57A, or the overhang edge 53 and the insertion groove 58. Therefore, it is possible to prevent the arm portion 42 from being bent and deformed even though the arm portion 42 has an elongated shape. Therefore, it is avoided that the deformed portion protrudes unnecessarily into the small cavity 32S, and smooth insertion / extraction of the small female terminal 26S into the small cavity 32S is ensured.
The guide grooves 52 and 52A and the ribs 57 and 57A, or the overhang edge 53 and the insertion groove 58 each function as a guide, and the retainer 40 is inserted smoothly.
[0030]
When the retainer 40 is held at the temporary locking position as described above, the female terminal is attached. When the small female terminal 26S is inserted into the corresponding small cavity 32S from the rear side, the small lance 33S is pushed in while being bent and deformed. When the small female terminal 26S is pushed into a predetermined position, the small lance 33S is restored and deformed into the locked portion 29. By engaging, the small female terminal 26S is primarily engaged. Similarly, the large female terminal 26L is inserted into the corresponding large cavity 32L from the rear, the large lance 33L is elastically locked, and the large female terminal 26L is also primarily locked.
[0031]
When the insertion of all the large and small female terminals 26S, 26L is completed, the retainer 40 is further pushed in from the temporary locking position, and the projection 59 is fitted into the front locking recess 55B instead of the temporary locking recess 55A. As shown in FIG. 10, the retainer 40 is held at the final locking position. Here, each locking projection 45 on the small female terminal locking portion 41S side enters the corresponding small cavity 32S and fits behind the jaw portion 30 of the small female terminal 26S inserted into the small cavity 32S, The small female terminal 26S is double-locked in the retaining state. On the other hand, each locking projection 47 on the large female terminal locking portion 41L side enters the corresponding large cavity 32L and fits behind the jaw portion of the large female terminal 26L inserted into the large cavity 32L. The terminal 26L is double-locked in the retaining state.
[0032]
At the same time, the slider 70 is attached to the female housing 20 in advance. The slider 70 is inserted into the insertion passage 24 from the left side surface of the female housing 20, for example, and is pushed into the advance position all at once. That is, first, the temporary lock piece 90 is pushed in while being bent and deformed, and the temporary lock piece 90 is fitted in the locking groove 93 while being restored and deformed along the way. At the end of the push-in, when the lock claw 86 rides on the bridge portion 89A, the lock piece 85 is bent and deformed, and when the connecting plate 72 hits the left side surface of the female housing 20, as shown in FIG. By passing over the bridge portion 89A, the lock claw 86 is fitted into the lock hole 89 while the lock piece 85 is restored and deformed, and is held at the advanced position.
[0033]
The female housing 20 is carried into the fitting work site with the male housing 10 with the slider 70 mounted at the forward position as described above. Then, prior to fitting both the housings 10 and 20, the slider 70 is returned to the retracted position. In that case, if the upper and lower gripping portions 83 (one of the lock pieces 85) of the slider 70 are gripped with fingers, the lock pieces 85 are bent inward and deformed, so that the lock claw 86 comes out of the lock hole 89 and is locked. Is released, the slider 70 is pulled while holding the grip portion 83. During this time, when the temporary locking piece 90 returns along the locking groove 93 and stops pulling when the protrusion 91 hits the edge of the locking groove 93, the slider 70 is held in the retracted position shown in FIG. It becomes.
[0034]
Then, the male housing 10 is fitted into the large hood portion 22 of the female housing 20 as shown by the arrow in FIG. In that case, the ribs 16, 17 and 18 provided on the male housing 10 side are fitted into the corresponding grooves 61, 62 and 63 provided on the female housing 20 side, and are fitted straight without being twisted. . Here, in the female housing 20, although the retainer 40 needs to be already transferred to the final locking position, it may be forgotten and held in the temporary locking position. At that time, as shown in FIG. 18, the detection portion 66 that is the inner edge of the through hole 65 of the retainer 40 faces the inner side of the inner edge 62 </ b> A of the horizontal groove 62. When entering, the corresponding end portion abuts against the detection portion 66, and further fitting is restricted.
[0035]
As a result, it is detected that the retainer 40 has not been pushed to the full locking position, that is, it is in a half-inserted state. Therefore, the retainer 40 may be pushed in again and held at the full locking position.
When the retainer 40 is held in a semi-insertion state close to the main locking position, the detection unit 66 slightly inwardly faces the inner edge 62A of the lateral groove 62 as shown by a chain line in FIG. It becomes a state. On the other hand, since the corners of the corresponding end portions of the horizontal ribs 16 are rounded 68 (FIG. 3), when the horizontal ribs 16 enter the horizontal grooves 62, the roundness 68 of the horizontal ribs 16 The retainer 40 is automatically shifted to the final locking position by hitting the edge and pushing it.
[0036]
When the fitting of both the housings 10 and 20 starts normally, the follower pin 77 on the male housing 10 side enters the inlet 75 of the cam groove 74 through the through hole 79 and further pushes the male housing 10 into the figure. 19, the follower pin 77 pushes the inner side edge (the upper side edge in the figure) of the retracting portion 80, so that the slider 70 moves by a predetermined dimension toward the advance position following the inclination. As a result, the follower pin 77 enters the start end 74 </ b> A side of the cam groove 74. At the same time, the follower pin 77 is hooked on the side edge on the near side of the retracting portion 80, thereby preventing the male housing 10 from coming off.
[0037]
Subsequently, as shown by the arrow in FIG. 19, the slider 70 is pushed toward the forward movement position. As a result, as shown in FIG. 20, the male housing 10 is gradually pushed into the female housing 20 side by mainly pressing the follower pin 77 with the side edge on the front side of the cam groove 74. When the slider 70 is pushed to the advanced position, as shown in FIG. 21, the follower pin 77 is also moved to the end portion 74B of the cam groove 74, whereby the male and female housings 10 and 20 are properly fitted. . When the slider 70 is pushed to the advanced position, as described above, the lock claw 86 of the lock piece 85 is fitted in the lock hole 89 and is locked in a state of being prevented from being removed (see FIG. 17). Is locked in the proper mating state.
[0038]
In order to remove the fitting between the housings 10 and 20, when the grip portion 83 of the slider 70 is gripped from the state shown in FIG. 21, the lock piece 85 is bent and deformed, and the lock is released. pull. Then, the male housing 10 is gradually pushed away from the female housing 20 by the side edge of the cam groove 74 mainly pushing the follower pin 77. When the slider 70 is pulled back to the retracted position, the follower pin 77 is returned to the inlet 75 of the cam groove 74. Subsequently, when the male housing 10 is pulled, the male housing 10 is removed while pulling the follower pin 77 through the hole 79. It can be removed from the female housing 20.
[0039]
As described above, according to the present embodiment, when the male and female housings 10 and 20 are initially fitted, the follower pin 77 enters the inlet 75 of the cam groove 74 and then presses the retracting portion 80, thereby causing the slider 70 to move. The follower pin 77 moves into the forward position by a predetermined amount, and the follower pin 77 enters the start end 74A side of the cam groove 74. As a result, the housings 10 and 20 are prevented from coming off, and the follower pin 77 has already entered the start end portion 74A of the cam groove 74, so that the slider 70 can be smoothly pushed toward the forward position. .
