Description

  The present invention relates to a lever type connector.

Conventionally, there is a lever type connector described in Patent Document 1. This is because the lever is attached to the first housing so as to be displaced between the initial position and the fitting position, and the cam follower is provided on the second housing, and both the housings are held in the state where the lever is held at the initial position. By fitting the cam follower shallowly, the cam follower enters the cam groove of the lever, and by displacing the lever from that state to the fitting position, both housings are fitted by the cam action by the engagement of the cam groove and the cam follower, The terminal fittings of both housings are connected to each other.
JP-A-8-78091

In the lever-type connector as described above, as a means for reducing the size, a structure in which the lever is formed in a substantially flat plate shape and is accommodated in an accommodation space provided in the first housing is conceivable. As a means for supporting the lever, a structure in which a support shaft is formed in the accommodation space and a bearing hole of the lever is fitted to the support shaft can be considered.
However, in such a configuration, it is necessary to move the lever in the thickness direction in the accommodation space when the bearing hole is fitted to the support shaft, so in the state where the lever is assembled, This leaves a space for moving the lever. For this reason, there is a concern that the lever may rattle in the thickness direction in the accommodation space.
The present invention has been completed based on the above situation, and an object thereof is to prevent rattling of the lever in the accommodation space.

  As a means for achieving the above object, according to the first aspect of the present invention, a substantially flat lever is accommodated in an accommodation space provided in the first housing, and the lever is rotated about a support shaft. Accordingly, the first housing and the second housing are fitted or detached, and the support shaft is provided in one of the accommodation space and the lever, and the accommodation space and the lever The other is provided with a bearing hole, and the lever is assembled in the housing space by fitting the support shaft and the bearing hole while displacing the lever in the plate thickness direction in the housing space. In a state in which the lever is assembled, a lever in which the assembly space for moving the lever when the support shaft and the bearing hole are fitted remains in the accommodation space. A displacement restricting means for restricting displacement of the lever in the plate thickness direction by entering the assembly space and allowing the side surface of the lever to come into contact with the first housing. It is characterized in that is provided.

  According to a second aspect of the present invention, in the first aspect of the present invention, the first housing is provided with a retainer that prevents a terminal fitting inserted into the first housing from being removed. The restricting means is characterized in that it is formed integrally with the retainer.

  The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the displacement restricting means is configured to sandwich the lever with an inner side surface of the accommodating space. .

<Invention of Claim 1>
When the lever is about to be displaced in the plate thickness direction, rattling of the lever in the plate thickness direction is prevented by contacting the side surface of the lever with the displacement regulating means that has entered the assembly space.

<Invention of Claim 2>
Since the displacement restricting means is integrally formed with the retainer as the terminal metal retaining means, the number of parts can be reduced as compared with the case where the displacement restricting means is a separate component from the retainer.

<Invention of Claim 3>
Since the lever is sandwiched between the displacement restricting means and the inner surface of the accommodation space, rattling in the thickness direction is reliably restricted.

<Embodiment 1>
A first embodiment of the present invention will be described below with reference to FIGS. The lever-type connector of the present embodiment is configured such that the first housing 10 and the second housing 60 are fitted and detached using the lever 30.

  The first housing 10 is made of synthetic resin and has a square block shape as a whole. A plurality of cavities 11 are formed side by side in the first housing 10, and in each cavity 11, a female terminal fitting 12 (terminal fitting which is a constituent element of the present invention) elongated in the front-rear direction is provided from the rear. The electric wire 13 inserted and connected to the rear end portion of the female terminal fitting 12 is led backward from the rear end surface of the first housing 10. The female terminal fitting 12 inserted into the cavity 11 is prevented from being pulled out by a well-known primary locking action by the lance 14 and is locked in a locking state by a well-known secondary locking action by a retainer 50 described later. It has become. The female terminal fitting 12 is formed with a secondary locking portion 12 a for locking the retainer 50.

  The first housing 10 is formed with a first accommodation space 15 (accommodation space which is a constituent feature of the present invention) disposed at a substantially central position in the left-right direction. The first accommodation space 15 is a narrow space as a whole (small dimension in the left-right direction), and is opened in a slit shape on the upper surface and both front and rear end surfaces of the first housing 10. The first accommodation space 15 is arranged at a substantially central position in the arrangement area of the plurality of cavities 11 arranged side by side.

A pair of front and rear retaining protrusions 16 a are formed on the outer periphery of the protruding end of the support shaft 16, and a guide slope 16 b is formed on the upper end of the protruding end of the support shaft 16. A rotation restricting protrusion 17 is formed on the left inner surface of the first accommodating space 15 so as to protrude rightward from a position obliquely above and below the support shaft 16. A space for assembling a lever 30 described later is provided between the extended end surface (right end surface) of the support shaft 16 and the right inner surface of the first accommodation space 15. That is, in the first accommodation space 15, the region on the left side of the extending end surface of the support shaft 16 (the region where the support shaft 16 is formed in the left-right direction) is accommodated after the lever 30 is accommodated and cam operation (rotation). A cam operating space 15a for performing dynamic displacement), and a region on the right side of the extended end surface of the support shaft 16 in the first accommodating space 15 is moved in the left-right direction when the lever 30 is assembled. This is an assembly space 15b secured for movement.

  At the front end portion of the first accommodation space 15, a rectangular flat plate-shaped bending holding piece 18 is formed which is located at the lower end portion thereof and is flush with the left inner surface of the first accommodation space 15. The bending holding piece 18 is configured to extend downward in a cantilevered manner, and can be elastically bent leftward (in the direction of retreating from the first accommodation space 15) with the upper end edge as a fulcrum. A holding projection 19 and a release projection 20 positioned in front of the holding projection 19 are formed at the lower end portion of the right outer surface of the bending holding piece 18 (the side surface flush with the left inner side surface of the first accommodation space 15). ing. A guide slope 20 a is formed at the front end of the release protrusion 20. In a state where the bending holding piece 18 is not elastically bent, the holding protrusion 19 and the release protrusion 20 protrude into the first accommodation space 15.

  The first housing 10 is formed with a second housing space 21 adjacent to the right side of the first housing space 15 and communicating with the assembly space 15 b of the first housing space 15. The second accommodation space 21 is open to the upper surface and both front and rear end faces of the first housing 10, and the second accommodation space 21 is also substantially in the arrangement region of the plurality of cavities 11 arranged side by side in the same manner as the first accommodation space 15. Located in the center position. The formation area of the second accommodation space 21 in the height direction is a range corresponding to the substantially upper half area of the first accommodation space 15.

  A lock arm 22 is accommodated in the second accommodation space 21. The lock arm 22 extends in the longitudinal direction as a whole, and the front end portion of the lock arm 22 is connected to the bottom surface of the second accommodation space 21 via a leg portion 22a. That is, the lock arm 22 is configured to extend rearward in a cantilevered manner, and can be elastically bent while tilting in the vertical direction with the leg portion 22a as a substantially fulcrum. A lock protrusion 23 is formed on the upper surface of the lock arm 22 so as to protrude upward from a substantially central position in the front-rear direction, and the rear end portion (extension end portion) of the lock arm 22 protrudes upward. The release operation unit 24 is formed. Further, the left outer surface of the lock arm 22 is recessed to the right of the right inner surface of the first accommodation space 15, and the recessed space serves as a relief portion 25.

A lever 30 is accommodated in the first accommodating space 15. Note that the vertical and horizontal directions in the following description will be described with reference to the state in which the lever 30 is rotated to the fitting position (see FIGS. 4, 8, and 15).
The lever 30 is made of synthetic resin, has a generally flat plate shape as a whole, and is formed by integrally forming the main body 31 and the cam operation unit 41. The main body 31 as a whole has a flat plate shape in which the plate thickness direction is directed in the left-right direction (the direction parallel to the direction in which the cavities 11 are arranged), and is long in the front-rear direction when viewed from the side. The shape is cut diagonally. The main body 31 includes a mother body 32 that occupies approximately 2/3 in the front-rear direction, and a form that extends obliquely upward from the lower end position of the front end of the mother body 32, that is, outside the main body 31 of the lever 30 The cam portion 33 has a shape extending in a cantilever manner along the periphery.

  A circular bearing hole 34 penetrating in the left-right direction (plate thickness direction) is formed in the base body portion 32, and a pair of notches 34 a are formed in the hole edge portion of the bearing hole 34. Further, a guide slope 32 a is formed on the left outer surface of the base body part 32 from the lower end edge of the base body part 32 to the bearing hole 34. Furthermore, a rotation restricting groove 35 having a shape in which the left side surface is cut off is formed at the rear end portion of the base portion 32. The front end surface of the mother body portion 32 faces the rear end surface of the cam portion 33 (fitting cam surface 36).

  The rear end surface of the cam portion 33 is a fitting cam surface 36, and the front end surface of the cam portion 33 is a separation cam surface 37. A cam groove 38 having a shape opened upward is formed between the fitting cam surface 36 and the front end surface of the base portion 32. The length of the front end surface of the base portion 32 constituting one groove side surface of the cam groove 38 is shorter than the length of the fitting cam surface 36 constituting the other groove side surface of the cam groove 38. Yes. That is, when compared with a lever (not shown) in which the two groove side surfaces constituting the cam groove have substantially the same length, in the lever 30 of the present embodiment, a part of the formation base (upper end portion) of one groove side surface. The vertical dimension is made smaller by cutting out.

  Between the front end edge of the base body part 32 and the rear end edge of the cam part 33, a reinforcing part 39 that is parallel to the main body part 31 and is thinner than the main body part 31 is stretched. In other words, the cam portion 33 is connected not only to the base end portion but also to the base body portion 32 over a region extending from the base end portion to the extending end. In addition, the cam portion 33 is formed with a holding recess 40 having a shape in which the left side surface is cut out.

  A cam operation portion 41 is integrally formed at the rear end portion of the main body portion 31 (matrix portion 32). The cam operation unit 41 is configured to rise slightly from the upper surface of the rear end portion of the mother body 32 and make the upper surface substantially horizontal. The left and right dimensions of the cam operation unit 41 are the same as the plate thickness dimension of the main body 31. From the left edge of the cam operation unit 41, the front and rear dimensions are the same as the cam operation unit 41, and the upper surface is the cam operation unit. A substantially rectangular widened portion 42 that is flush with 41 is extended. On the other hand, from the right edge of the cam operation unit 41, the front-rear dimension is smaller than that of the cam operation unit 41, the upper surface is flush with the cam operation unit 41, and the front end surface is flush with the front end surface of the cam operation unit 41. A substantially rectangular interference restricting portion 43 is extended. And the upper surface of the cam operation part 41, the upper surface of the widening part 42, and the upper surface of the interference control part 43 are the flat finger contact surfaces 44 which have an area large enough for an operator to touch a finger.

The first housing 10 is formed with a retainer mounting hole 45 that opens on the lower surface thereof. The area where the retainer mounting hole 45 is formed is substantially the center position of the first housing 10 in the front-rear direction. The retainer mounting hole 45 is also communicated with the cavity 11 and the first accommodation space 15. A retainer 50 is assembled into the retainer mounting hole 45 from below.
The retainer 50 is made of a synthetic resin, and the retainer 50 includes a plurality of removal restricting portions 51 corresponding to the cavities 11 and a displacement restricting rib 52 corresponding to the assembly space 15b of the first accommodation space 15 (main book). Displacement restricting means) which is a constituent element of the invention is formed. The retainer 50 is attached to the first housing 10 at any one of the temporary locking position and the final locking position above the temporary locking position by known locking means. It can move up and down between the locking position and the main locking position.

The second housing 60 is made of synthetic resin, and is formed by integrally forming a terminal holding portion 61 and a rectangular tubular hood portion 62 that extends forward from the terminal holding portion 61. A male terminal fitting 63 is accommodated in the terminal holding portion 61, and a tab 63 a at the front end of the male terminal fitting 63 protruding from the front end face of the terminal holding portion 61 is surrounded by a hood portion 62.
The upper surface plate of the hood portion 62 is formed with a lock receiving portion 64 that is positioned substantially at the center of the hood portion 62 in the left-right direction and protrudes from the lower surface (inner surface) of the upper surface plate. At the right position (left position in FIG. 11) of the lock receiving portion 64 in the hood portion 62, a function generating portion 65 having a flat plate shape with the plate thickness direction directed in the left-right direction is formed. The function generator 65 includes a substantially rectangular support plate 66 extending forward from the back end surface of the hood 62 (front end surface of the terminal holding portion 61), and a first extension extending forward from the upper end of the support plate 66. 1 rib 67. The upper end edge of the support plate portion 66 is continuous with the upper surface plate of the hood portion 62, but the lower end edge of the support plate portion 66 is arranged at a position spaced above the single side plate of the hood portion 62. The upper end edge of the first rib 67 is connected to the upper surface plate of the hood portion 62, similarly to the support plate portion 66.

  A substantially cylindrical fitting cam follower 68 is formed on the right side surface of the support plate portion 66 so as to protrude from a position at a substantially middle height of the hood portion 62 in the vertical direction. Similarly, a detaching cam follower 69 is formed on the right side surface of the support plate portion 66 so as to protrude from a position obliquely downward and rearward with respect to the fitting cam follower 68. The front end surface of the detachable cam follower 69 is a detachable sliding contact surface 69a that is inclined with respect to the fitting direction of the housings 10 and 60. Further, on the right side surface of the support plate portion 66, a protruding release portion 70 protruding from a position below the detaching cam follower 69 is formed. The rear end surface of the release portion 70 is a guide slope 70a. Further, a second rib 71 is formed at a position on the left side of the lock receiving portion 64 in the hood portion 62 so as to be connected to the upper surface plate. The formation range of the second rib 71 in the front-rear direction is a region extending from the front end of the first rib 67 to the back end surface of the hood portion 62. Further, the lower surface of the first rib 67 and the lower surface of the second rib 71 have the same height.

Next, the operation of this embodiment will be described.
First, the process of assembling the lever 30 to the first housing 10 will be described. At the time of assembly, the lever 30 is in the posture shown in FIGS. 8 and 15, that is, the posture when the lever 30 is rotated to the fitting position, and the inside of the assembly space 15 b of the first housing space 15 from above the first housing 10. Plug in. At this time, the guide slope 32a connected to the bearing hole 34 is made to correspond to the tip of the support shaft 16, and the tip surface of the support shaft 16 is brought into sliding contact with the guide slope 32a. When the lever 30 is dropped to a predetermined assembly height and the lever 30 is moved to the left in the thickness direction, the retaining protrusion 16a of the support shaft 16 is supported while passing through the notch 34a of the bearing hole 34. The shaft 16 and the bearing hole 34 are fitted. As a result, the lever 30 rotates around the support shaft 16 with respect to the first housing 10 in a state where the lever 30 is housed in the first housing space 15 and arranged in the vicinity of the left side of the lock arm 22. The lever 30 is in the fitting position when it is assembled and the assembly process is completed.

  After the lever 30 is assembled, the retainer 50 is attached to the retainer mounting hole 45 of the first housing 10 from below, and is held at the temporary locking position by known locking means. In this state, the removal restricting portion 51 is retracted below the insertion path of the female terminal fitting 12 in the cavity 11, so that the female terminal fitting 12 can be inserted into and removed from the cavity 11. When the female terminal fitting 12 is inserted in a state where the retainer is in the temporary locking position, and then the retainer 50 is pushed up to the full locking position, the secondary locking portion 12a of the female terminal fitting 12 into which the removal restricting portion 51 has been inserted. Thus, the female terminal fitting 12 is held in the retaining state.

  When the lever 30 is assembled in the first housing space 15, the lever 30 is disposed in the left cam operation space 15 a of the first housing space 15, and is an assembly that is the right region of the first housing space 15. Since the work space 15b is in a vacant state, there is a concern that the lever 30 may be illegally displaced toward the assembly space 15b. However, in this embodiment, by attaching the retainer 50 to the first housing 10, the displacement regulating rib 52 advances into the assembly space 15 b, and the left side surface of the displacement regulating rib 52 is relative to the right side surface of the lever 30. Therefore, there is no possibility that the lever 30 is displaced toward the assembly space 15b.

  When the first housing 10 to which the lever 30 is attached and the second housing 60 are fitted, the lever 30 assembled at the fitting position is previously rotated to the initial position shown in FIG. When the lever 30 is rotated to the initial position, the rotation restricting groove 35 of the lever 30 is fitted and brought into contact with the rotation restricting protrusion 17 of the first accommodating space 15, so that the lever 30 is further rotated. Be regulated. Further, when the lever 30 reaches the initial position, the holding recess 40 of the lever 30 is engaged with the holding projection 19 of the first housing space 15, whereby the lever 30 is further rotated and returned to the fitting position side. Rotation to is restricted. Thus, the lever 30 is held at the initial position.

  From this state, the housings 10 and 60 are brought close to each other, and the first housing 10 is shallowly inserted into the hood portion 62. Then, as shown in FIG. 13, the fitting cam follower 68 is positioned so as to correspond to the tip of the fitting cam surface 36 of the lever 30, and the release portion 70 of the second housing 60 is the release protrusion of the first housing 10. 20 and is elastically bent in a direction in which the bending holding piece 18 is separated from the lever 30 (front side in FIG. 13). Along with this elastic bending, the holding projection 19 is disengaged from the holding recess 40 of the lever 30, and the lever 30 is released from the movement restriction and is allowed to rotate to the fitting position side.

  From this state, the lever 30 is turned to the fitting position side (clockwise direction in FIGS. 13 to 15) while pushing the cam operation unit 41 by pushing the finger contact surface 44 at the rear end of the lever 30. When moved, the housings 10 and 60 are pulled toward each other by the cam action caused by the engagement between the fitting cam surface 36 and the fitting cam follower 68. During this time, the lock projection 23 interferes with the lock receiving portion 64, and as shown in FIG. 14, the lock arm 22 is elastically bent while displacing the release operation portion 24 (rear end portion) downward. It is done. In addition, the function generating portion 65 enters the assembly space 15b and faces the right outer surface of the lever 30 and the right inner surface of the assembly space 15b in a state of being close to or in contact with the second rib 71. However, the first housing 10 and the second housing 60 are in an oblique posture by almost tightly entering the slit-like space between the right outer surface of the lock arm 22 and the right inner surface of the second accommodation space 21. A state (kojiri) is avoided. Further, when the release portion 70 passes through the release protrusion 20, the bending holding piece 18 is elastically restored.

  Then, when the lever 30 reaches the fitting position shown in FIG. 15 through the state shown in FIG. 14, the lock receiving portion 64 passes through the lock protrusion 23, whereby the lock arm 22 is elastically restored, and the lock protrusion 23. And the lock receiving portion 64 are locked in the front-rear direction, and the locking action locks the housings 10 and 60 in a state where they are restricted from being detached. Further, when the fitting cam follower 68 is in contact with the inner end of the cam groove 38, the further rotation of the lever 30 (in the direction of returning to the initial position) is restricted. By the above, the fitting operation of both the housings 10 and 60 is completed, and the tab 63a of the male terminal fitting 63 and the female terminal fitting 12 are connected so as to be conductive.

  Further, in a state in which both housings 10 and 60 are properly fitted, the cam operation portion 41 of the lever 30 is positioned side by side (left side) of the release operation portion 24 of the lock arm 22 and is located at substantially the same height. The interference regulating portion 43 of the lever 30 is positioned so as to overlap from above the region slightly ahead of the release operation portion 24 on the upper surface of the rear end portion of the lock arm 22. However, since the downward displacement of the interference restricting portion 43 is restricted by the contact between the fitting cam follower 68 and the cam groove 38 as described above, even if a downward external force acts on the interference restricting portion 43, The interference regulating portion 43 does not descend and elastically bend the lock arm 22 in the unlocking direction. In addition, although the interference regulating unit 43 and the cam operation unit 41 are located in the vicinity of the release operation unit 24, the heights of the upper surfaces (finger contact surfaces 44) of the interference regulation unit 43 and the cam operation unit 41 are as follows. The position is set slightly higher than the upper surface of the release operation unit 24.

  When the two housings 10 and 60 that are locked in the fitted state are removed, the lock projection 23 is released from the lock receiving portion 64 by pushing down the release operation portion 24 and elastically bending the lock arm 22. Both housings 10 and 60 are brought into an unlocked state in which they can be detached. In this state, the cam operation unit 41 is picked to rotate the lever 30 from the fitting position to the initial position side. Then, the first housing 10 is pushed out of the hood portion 62 by the cam action caused by the engagement between the detaching cam surface 37 and the detaching cam follower 69, and the housings 10 and 60 are gradually separated from each other. During this time, the fitting cam follower 68 moves in the cam groove 38, and the fitting cam surface 36 and the fitting cam follower 68 remain opposed to each other in the front-rear direction.

When the lever 30 reaches the initial position, the fitting cam follower 68 is disengaged from the tip of the fitting cam surface 36 and is positioned above the upper end (extending end) of the cam portion 33. Thereafter, the two housings 10 and 60 can be detached from this state.
During the rotation of the lever 30 from the fitting position to the initial position, the guide inclined surface 20a of the release protrusion 20 abuts on the release portion 70, whereby the bending holding piece 18 is elastically bent in a direction away from the lever 30, When the lever 30 reaches the initial position, the bending holding piece 18 is elastically restored and the holding projection 19 and the holding recess 40 are fitted, and the lever 30 is restricted from rotating in both forward and reverse directions at the initial position. Retained.

As described above, in the present embodiment, since the lever 30 is disposed at a substantially central position in the arrangement area of the plurality of cavities 11, the fitting caused by the friction between the female terminal fitting 12 and the male terminal fitting 63 is provided. The combined resistance is distributed to the left and right sides of the lever 30. Therefore, there is no twist between the housings 10 and 60 during the fitting process and the detaching process.
Further, since the plate thickness direction of the lever 30 is oriented substantially parallel to the arrangement direction of the plurality of cavities 11, the first housing 10 can be reduced in size in the arrangement direction of the cavities 11.
The lever 30 can be attached to and detached from the first housing 10, and the first housing 10 and the second housing 60 can be engaged with each other to lock the two housings 10 and 60 in a fitted state. Since the lock means (the lock arm 22 and the lock receiving portion 64) are provided, the lever-type connector of this embodiment can be used as a connector without a lever, and the housings 10 and 60 can be connected to each other even without a lever. It can be locked in the fitted state.
Further, since the locking means (the lock arm 22 and the lock receiving portion 64) is disposed at a substantially central position in the direction in which the plurality of cavities 11 are arranged, the housing 10 and 60 are reliably tilted without causing an inclination. Can be held in a locked state. In addition, since the second accommodation space 21 in which the lock arm 22 as the locking means is accommodated and the first accommodation space 15 in which the lever 30 is accommodated communicate with each other, a partition wall is provided between the two spaces. As compared with the first housing 10, the first housing 10 can be downsized.

Further, in the lever 30 of the present embodiment, the flesh portion for forming the fitting cam surface 36 and the flesh portion for forming the detaching cam surface 37 are the cam portion 33 which is a common flesh portion. One cam surface (removal cam surface 37) is formed along the outer peripheral edge of the lever 30. Accordingly, a lever (that is, the two groove side surfaces of the cam groove are the mating cam surface and the detaching cam surface). Compared to the lever), the miniaturization is realized.
Further, since the lever 30 has a substantially flat plate shape, the lever 30 can be reduced in size as compared with a lever having a pair of arm portions extending from both ends of the operation portion.
Further, since the cam portion 33 is extended from the base body portion 32 in a cantilevered manner, the cam portion 33 is displaced relative to the base body portion 32 during fitting or detachment of the housing, and the housings 10 and 60 are fitted. There is a concern that the combined operation or the disengagement operation may not be performed correctly. However, in this embodiment, since the cam part 33 and the base part 32 are connected by the reinforcing part 39, there is no possibility that the cam part 33 is displaced relative to the base part 32 (the lever 30 is deformed).

When the lever 30 is assembled to the first housing 10, the assembly space 15 b for moving the lever 30 when the support shaft 16 and the bearing hole 34 are fitted into the first housing space 15. Remains. However, in the present embodiment, the assembly space 15b is effectively used as a space for allowing the function generating portion 65 of the second housing 60 to enter as the two housings 10 and 60 are fitted together. It is not finished.
Further, even when the lever 30 is about to be displaced in the plate thickness direction in a state where both the housings 10 and 60 are fitted, the outer surface of the lever 30 abuts on the function generating portion 65, so that the lever 30 moves in the plate thickness direction. Backlash is prevented.
Moreover, since the function generation | occurrence | production part 65 is set as the form which pinches | interposes the lever 30 between the right inner surface of the 1st accommodating space 15, the backlash | playback in the plate | board thickness direction of the lever 30 is controlled reliably.
In addition, since the function generating portion 65 functions as a base for forming the fitting cam follower 68 and the detaching cam follower 69, the function generating portion 65 of the second housing 60 can be compared with the case where a dedicated cam follower supporting means is provided separately from the function generating portion 65. The shape is simplified.

Further, in the state where the retainer 50 is assembled to the first housing 10, even if the lever 30 is about to be displaced in the plate thickness direction, the right outer surface of the lever 30 is moved to the displacement regulating rib 52 entering the assembly space 15 b. Prevents the lever 30 from rattling in the plate thickness direction.
Further, since the displacement restricting rib 52 is integrally formed with the retainer 50 which is a retaining means for the female terminal fitting 12, the number of parts is smaller than when the displacement restricting means is a separate component from the retainer. I'm done.
Further, since the lever 30 is sandwiched between the left outer surface of the displacement restricting rib 52 and the right inner surface of the first accommodating space 15, rattling in the plate thickness direction is reliably restricted.

In addition, when the lever 30 is disposed in the vicinity of the lock arm 22 and the housings 10 and 60 are fitted, the interference restricting portion 43 provided on the lever 30 prevents foreign matter from being applied to the release operation portion 24 of the lock arm 22. Since the interference is regulated, the lock arm 22 is prevented from being illegally displaced in the unlocking direction due to the interference of the foreign matter.
In addition, since the cam operation portion 41 of the lever 30 is disposed in the vicinity of the release operation portion 24 of the lock arm 22, a cam operation for displacing the lever 30 can be performed following the lock release operation by the lock arm 22, Workability is good.
In the present embodiment, the lever 30 has a substantially flat plate shape and is displaced in a direction substantially parallel to the plate surface (a direction perpendicular to the plate thickness direction). There is concern that the area of the portion 41 cannot be secured sufficiently large. However, in the present embodiment, since the interference restricting portion 43 is extended from the cam operation portion 41 in the plate thickness direction, the interference restricting portion 43 can also be used as the cam operation portion 41 and the operability of the lever 30 is improved. Is good.
