According to a fourth aspect of the present invention, in the third aspect, the interference wall is formed so as to have a gap on the outer peripheral surface of the housing, and can prevent opening of the arm portion when the lever is operated. The feature is that it is configured as a wall.
[0009]
Function and effect of the present invention
<Invention of claim 1>
When assembling the electric wire cover, first, the electric wire cover is brought into contact with the housing in a direction substantially orthogonal to the lead-out surface, and then the electric wire cover is slid parallel to the lead-out surface of the housing. When the wire cover reaches the regular assembling position, the bent lock portion returns elastically and is locked by the lock receiving portion. At this time, any one of the front end surface in the extending direction on the free end side of the lock portion and the opposing surface of the lock receiving portion can be brought into contact with each other by projecting toward the other surface. Since the backlash filling portion is provided, the lock portion and the lock receiving portion can be engaged with each other in a closely fitted state, and rattling of the wire cover is suppressed.
[0010]
<Invention of Claim 2>
Since the backlash filling portion is formed by a tapered surface forming a so-called semi-lock structure, there is a concern that the wire cover may be detached from the housing, but after the two housings are fitted, the wire cover is mated via the lever. Since the wire cover is securely locked to the side housing, the detachment of the wire cover can be prevented.
[0011]
<Invention of Claim 3>
If the lever is set to the initial position, the non-interfering part of the arm accepts the interference wall provided on the outer wall surface of the housing to enable the assembling of the wire cover to the housing, while moving the lever to a position other than the initial position. If set, the interference part of the arm part abuts against the interference wall to prevent the assembly, so that the state in which the wire cover is assembled to the housing ensures that the lever is set to the initial position. . When the lever is at the initial position, the entrance of the cam groove of the arm portion is open toward the cam pin of the mating housing, and the lever can be turned. The operation can be shifted to the fitting operation with the side housing.
[0012]
<Invention of Claim 4>
Generally, in a lever-type connector, when the lever is rotated in a state where the cam groove formed in the arm portion of the lever and the cam pin of the mating connector are engaged, the cam pin is formed in the cam groove by the mating resistance of the connector. Since the inner wall is strongly pressed, a force acts on the arm portion of the lever in the opening direction. However, in the present invention, the opening prevention wall is formed in the housing, so that the lever is prevented from being expanded and deformed. Further, the opening prevention wall also has a function as an interference wall.
[0013]

The lever 30 can be rotated between an initial position and a rotation completed position. In the state where the lever 30 is in the initial position, the entrance of the cam groove 33 is opened downward, and the cam pins 42 of the second housing 40 are inserted into the cam grooves as the first housing 10 and the second housing 40 are fitted shallowly. It can be greeted at 33 entrances. When the lever 30 is rotated from the initial position to the rotation completed position, the housings 10 and 40 are attracted to each other by the engagement between the cam groove 33 and the cam pin 42, and the fitting proceeds, and the housing 30 is rotated to the rotation completed position. Then, the operating portion 32 of the lever 30 is locked to the locking projection 24 at the front of the wire cover 20.
[0023]
A peripheral portion 34 concentric with the bearing portion 31A is provided on the outer peripheral side of the arm portion 31. The outer region bounded by the peripheral portion 34 is formed by the opening preventing walls 13B and 13C and the first housing 10A. And a thin fitting portion 35 which can enter into the gap between the two. The entrance of the cam groove 33 is opened by a cutout in the middle of the fitting portion 35 in the extending direction. The rear end side of the peripheral edge portion 34 in the turning direction of the lever 30 from the initial position to the turning completion position is an interference portion 34A that can interfere with the opening prevention walls 13B and 13C when assembled to the wire cover 20. The front end side of the peripheral portion 34 in the rotation direction is a non-interference portion 34B that is drawn inward from the interference portion 34A and is continuous with the interference portion 34A in a stepwise manner. In the arm portion 31, the fitting portion 35 in the outer region of the interference portion 34A is formed to be narrower than the fitting portion 35 in the outer region of the non-interference portion 34B.
[0024]
Here, when the lever 30 is set to the initial position and the wire cover 20 is assembled from above with respect to the contact position on the rear surface of the first housing 10 in this state, the non-interference portion 34B outside the arm portion 31 The wire cover 20 fits into the gap between the first housing 10 and the opening preventing wall 13B of the front wall, and the portion of the fitting portion 35 that fits into the gap of the front opening preventing wall 13B. In the process of sliding from the contact position to the regular assembling position, only the inside of the area where the front opening prevention wall 13B is formed is moved. Therefore, in both of the process of assembling the wire cover 20 at the contact position and the process of sliding the wire cover 20 from the contact position to the regular assembling position, the non-interfering portion 34B of the arm portion 31 has the front opening prevention wall. There is no interference with 13B or the supporting portions 14A and 14B. In the state where the wire cover 20 is in the contact position, as shown in FIG. 4, the fitting portion 35 is not fitted in the gap between the rear opening prevention wall 13 </ b> C and the first housing 10. When the cover 20 reaches the regular assembling position, as shown in FIG. 6, the fitting portion 35 in the outside area of the non-interference portion 34B is fitted into the gap between the rear opening prevention wall 13C and the first housing 10. That is, in this state, the fitting portion 35 is fitted into the gap between the front and rear opening preventing walls 13B and 13C, and the opening of the arm portion 31 is reliably prevented.
[0025]
On the other hand, as shown in FIG. 7, when the lever 30 is set to a position other than the initial position, if the wire cover 20 is to be assembled at the contact position on the rear surface of the first housing 10, the interference portion of the arm portion 31 Although the fitting portion 35 in the outer region of 34A fits into the gap between the first housing 10 and the front opening preventing wall 13B, the interference portion 34A abuts against the arc-shaped portion 13A of the opening preventing wall 13B during assembly, so that the fitting is performed. The depth is shallower than in the case of the fitting portion 35 in the outside area of the non-interference portion 34B. In this state, the wire cover 20 is separated from the first housing 10 and does not reach the contact position. That is, the present embodiment has a configuration in which the wire cover 20 cannot be assembled to the first housing 10 unless the lever 30 is set to the initial position. It functions as an interference wall for preventing the electric wire cover 20 from being attached.
Note that a first elastic locking piece 31B and a second elastic locking piece 31C are formed on the arm 31. Each of the elastic locking pieces 31B and 31C has a direction in which the lever 30 rotates. It extends in a cantilever manner in a substantially radially outward direction that intersects, and is capable of elastically flexing outward in a direction substantially parallel to the rotation center axis of the lever 30. In a state where the lever 30 is in the initial position and before being assembled to the first housing 10, the first elastic locking piece 31B is locked with a first locking portion (not shown) provided on the wire cover 20. It is possible. Further, in a state where the lever 30 is in the initial position and after being assembled to the first housing 10, the second elastic locking piece 31 </ b> C is a second locking portion (not shown) provided on the wire cover 20. And can be locked. That is, in each case, the lever 30 is held at the initial position.
[0026]
Next, the operation of the present embodiment will be described.
In order to assemble the wire cover 20, first, with the lever 30 set to the initial position, as shown in FIG. 4, assemble the wire cover 20 with respect to the first housing 10 in a direction orthogonal to the rear surface.

Accordingly, the fitting portion 35 of the arm portion 31 in the outer region of the non-interference portion 34B is fitted into the gap between the front opening prevention wall 13 and the first housing 10. Next, the wire cover 20 at the contact position is moved rearward. Then, as shown in FIG. 5, the ribs 15A, 15B and the grooves 21A, 21B start to be fitted, and the electric wire cover 20 is guided by the fitting between the ribs 15A, 15B and the grooves 21A, 21B. It slides parallel to the rear surface of the housing 10 to reach the regular assembling position. During this time, the lock projection 22D slides on the upper surface of the first housing 10 while bending the lock piece 22A as shown in FIG. At the same time that the wire cover 20 reaches the regular assembling position, the lock projection 22D is fitted into the lock receiving portion 16. In this state, the lock projection 22D and the lock receiving part 16 are fitted in a tightly fitted state as shown in FIG. 6, so that the wire cover 20 is securely attached to the housing 10 without rattling in the front-rear direction. Is locked. Further, the fitting portion 35 of the arm portion 31 in the outer region of the non-interference portion 34B is fitted from only the gap between the front opening preventing walls 13B to a state fitted into the gap between the front and rear opening preventing walls 13B and 13C. Transition. Thus, the assembly on the first housing 10 side is completed.
[0027]
Next, in order to fit the first and second housings 10 and 40, first, as shown in FIGS. Then, the cam pin 42 is fitted into the entrance of the cam groove 33. Subsequently, by gripping the operation unit 32 and rotating the lever 30 toward the rotation completion position, the fitting of the two housings 10 and 40 is completed.
[0028]
As described above, in the present embodiment, the front surface of the lock protrusion 22D located at the front end in the extending direction on the free end side of the lock portion 22 has the second tapered surface inclined downward so as to form a so-called semi-lock structure. 22E, and the front facing surface of the lock receiving portion 16 is a first tapered surface 16A having a form corresponding to the second tapered surface 22E. As a result, it is reliably locked without moving in the front-rear direction. As a result, rattling of the wire cover 20 is suppressed.
[0029]
Further, the tapered surfaces 22E and 16A are configured so as to guide the locking of the lock portion 22 in the disengagement direction when the wire cover 20 is moved in a direction opposite to the direction toward the regular assembling position. Although there is a concern that the wire cover 20 may be detached from the first housing 10 due to the presence of the first housing 10, the wire cover 20 is securely locked to the second housing 40 by the lever 30. After that, the detachment of the wire cover 20 can be reliably prevented.
[0030]
When the lever 30 is set to the initial position, the fitting portion 35 in the outer region of the non-interference portion 34B of the arm portion 31 is fitted into the gap between the front opening preventing wall 13B and the first housing 10, and the front opening preventing wall 13B. 13B, the electric wire cover 20 is assembled to the first housing 10 while the lever 30 is set to a position other than the initial position, so that the interference portion 34A of the arm portion 31 abuts against the front opening prevention wall 13B. Prevent the assembly. That is, the state in which the wire cover 20 is attached to the first housing 10 guarantees that the lever 30 is set to the initial position. Therefore, after that, it is possible to quickly shift to the fitting operation with the second housing 40 that is the mating side.
