  The invention according to claim 5 is the one according to any one of claims 1 to 4, wherein the first member includes a locking portion on the lever side when the lever reaches the fitting completion position. It is characterized in that a lock portion for holding the lever at the fitting completion position is formed by locking the lever.

<Invention of Claims 1 to 3>
When the second member is attached to the first member, the locking between the locking portions is released by the releasing portion, so that the lever can be moved. Further, when the attachment of the second member to the first member is incomplete, since the locking portions remain locked, the lever remains in a state where movement is restricted. The attachment state of the second member relative to the first member can be detected based on whether or not the movement of the lever is permitted.

<Invention of Claim 4>
In the state where the lever is held at the initial position, if an operating force exceeding the locking force between the tapered surface and the other-side locking portion is applied to the lever, the elastic locking piece elastically bends and the taper surface The lever moves from the initial position to the mating completion position side by sliding with the mating locking portion.

<Invention of Claim 5>
The locking part on the lever side also has a function as a locking means for holding the lever in the fitting completion position, so compared to the case where a dedicated locking means is formed on the lever separately from the locking part. The shape of the lever can be simplified.

<Embodiment 1>
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The lever-type connector 1 of the present embodiment includes a synthetic resin housing 10 (second member which is a component of the present invention) and a synthetic resin wire cover 20 assembled with the housing 10 (which is a component of the present invention. 1st member) and the synthetic resin lever 40 attached to the electric wire cover 20 so that rotation is possible.

  As a whole, the housing 10 has a small width and a long shape in the front-rear direction. In the housing 10, a plurality of cavities 11 penetrating in the vertical direction are formed side by side in the front-rear direction. A terminal fitting 12 is inserted into each cavity 11 from an opening on the upper surface side of the housing 10. An electric wire 13 is connected to the terminal fitting 12 so as to be conductive, and the electric wire 13 is led out from the upper surface of the housing 10. A pair of left and right communication grooves 14 that extend linearly in the front-rear direction (direction parallel to the assembly direction of the electric wire cover 20 and the housing 10) and communicate with the cavity 11 are formed on the left and right outer surfaces of the housing 10. Yes. On the front end surface of the housing 10, a release portion 15 is formed so as to protrude.

  The electric wire cover 20 includes a pair of left and right side walls 21, a front wall 22 configured to connect front end edges of the left and right side walls 21, an upper surface wall 23 configured to connect upper end edges of the left and right side walls 21, and both left and right sides The bottom wall 26 connecting the lower edges of the wall 21 is integrally formed, and has a box shape opened to the outside on the rear surface. The lower space of the inner space of the electric wire cover 20 is an accommodating space 24 for accommodating the housing 10, and the upper space is an arrangement for bending and arranging the electric wires 13 led out from the housing 10. A search space 25 is formed.

  A pair of left and right retaining ribs 27 extending in a straight line in the front-rear direction are formed in a projecting manner at a height corresponding to the accommodation space 24 in the inner surfaces of the left and right side walls 21. A pair of support shafts 28 are formed on the outer surfaces of the left and right side walls 21 so as to project the lever 40 in a rotatable manner. The front wall 22 is formed with a locking hole 29 (a locking portion which is a constituent feature of the present invention) penetrating in the front-rear direction. A portion on the front end side of the upper surface wall 23 is inclined so as to have a downward slope toward the front in order to avoid interference with the lever 40. A lock hole 30 (a lock portion which is a constituent element of the present invention) penetrating in the vertical direction is formed at a position slightly behind the center 1 in the front-rear direction in the upper surface wall 23.

  The lever 40 includes a plate-like operation portion 41 and a pair of plate-like arm portions 42 that extend symmetrically from the left and right side edges of the operation portion 41. Both left and right arm portions 42 are formed with bearing holes 43 penetrating in the left-right direction. A gear-like cam function part 44 having a plurality of engaging claws extending radially (outward in the radial direction) with the bearing hole 43 as the center is formed on the outer surfaces of the left and right arm parts 42.

  The lever 40 is engaged with the support shaft 28 by a bearing hole 43 formed in the arm portion 42, so that the lever 40 is positioned between the initial position shown in FIGS. 1 to 4 and the fitting completion position shown in FIG. 5. It is supported so that it can be rotated. In a state where the lever 40 is in the initial position, the operation unit 41 faces the outer surface (front surface) of the front wall 22 of the wire cover 20 so as to overlap substantially in parallel. In a state where the lever 40 is in the fitting completion position, the operation unit 41 faces the outer surface (upper surface) of the upper surface wall 23 so as to be substantially parallel.

  The operation unit 41 includes a pair of left and right main body portions 45, a plate-like elastic locking piece 46 (a locking portion that is a constituent of the present invention) disposed between the left and right main body portions 45, and It comprises a hinge portion 47 that connects the left and right main body portions 45 and the elastic locking piece 46. The main body 45 is continuous at a right angle to the arm 42 at the outer side edge. The hinge portion 47 is disposed at a position close to the center in the rotation direction of the lever 40 among the left and right side edges of the elastic locking piece 46.

  Of both ends of the elastic locking piece 46 in the rotation direction of the lever 40, the end on the front side in the movement direction when the lever 40 is rotated from the fitting completion position to the initial position is a locking end 48. ing. A locking projection 49 is formed on the surface of the locking end 48 facing the wire cover 20. Further, the end of the elastic locking piece 46 on the front side in the movement direction when the lever 40 is rotated from the initial position to the fitting completion position is a release operation piece 50 inclined so as to move away from the wire cover 20. Yes.

  The elastic locking piece 46 is always maintained in the locking posture shown in FIG. 3, but tilts like a seesaw into the releasing posture shown in FIG. 4 with the hinge portion 47 as a fulcrum while elastically deforming the hinge portion 47. It can be displaced.

  When the lever 40 is in the initial position and the elastic locking piece 46 assumes the locking posture, the locking projection 49 can be locked with the locking hole 29. When the lever 40 is in the initial position and the elastic locking piece 46 is in the locking position, when the outer surface of the release operation piece 50 is pushed, the locking projection 49 is displaced in the direction of disengaging from the locking hole 29.

  When the lever 40 is in the fitting completion position and the lever 40 assumes the locking posture, the locking projection 49 can be locked with the lock hole 30. When the lever 40 is in the fitting completion position and the elastic locking piece 46 is in the locked posture, when the outer surface of the release operation piece 50 is pushed, the locking projection 49 is displaced in the direction of disengagement from the lock hole 30. .

  Next, the operation of this embodiment will be described. When the lever connector 1 is assembled, the lever 40 is attached to the electric wire cover 20 before the electric wire cover 20 and the housing 10 are assembled. At this time, the lever 40 is displaced to the initial position. Then, since the latching protrusion 49 latches in the latching hole 29, the lever 40 is restricted from rotating to the fitting completion position side and is locked at the initial position. At this time, the locking protrusion 49 has a large locking margin and is securely locked because almost the entire region in the protruding direction is locked with the locking hole 29.

  On the other hand, in the housing 10, the terminal fitting 12 is inserted into the cavity 11 so that the electric wire 13 is led out from the upper surface of the housing 10. When all the terminal fittings 12 are inserted, the assembly of the housing 10 and the terminal fitting 12 is completed. Thereafter, the housing 10 is assembled to the electric wire cover 20 from the rear side and is inserted into the accommodation space 24. At the time of assembly, the retaining rib 27 of the wire cover 20 is fitted into the communication groove 14 of the housing 10, so that the housing 10 is attached to the wire cover 20 in the vertical direction (direction perpendicular to the assembly direction of the housing 10). Positioned against. Further, the left and right side walls 21 are in sliding contact with the outer surface of the housing 10, whereby the housing 10 is positioned with respect to the electric wire cover 20 in the left and right direction (the direction orthogonal to the assembly direction of the housing 10).

  In the process of assembling the housing 10, if any of the terminal fittings 12 among the plurality of terminal fittings 12 is incompletely inserted, the rectangular tube portion 12 a at the tip of the terminal fitting 12 is positioned upward. Since it shifts and corresponds to the communication groove 14, the rectangular tube portion 12 a interferes with the retaining rib 27, and the further assembling operation of the housing 10 is restricted by this interference. Therefore, when the assembly of the housing 10 is restricted during the operation, it can be detected that the terminal fitting 12 in the half-inserted state exists.

  When the housing 10 is assembled to a proper position with respect to the electric wire cover 20, the front surface of the housing 10 abuts against the front wall 22 of the electric wire cover 20 and is stopped in front, and a retaining means (not shown) Withdrawal is regulated. In the housing 10, the retaining rib 27 of the electric wire cover 20 is engaged with the rectangular tube portion 12 a of the terminal metal 12, so that the terminal metal 12 is held in a retaining state. Further, the plurality of electric wires 13 led out from the housing 10 are bent backward in the wiring space 25 of the electric wire cover 20 and led out of the electric wire cover 20 from the opening on the rear surface of the electric wire cover 20. Thus, the assembly work of the housing 10 is completed, and the lever-type connector 1 is completed.

  When the housing 10 is correctly assembled, the release portion 15 of the housing 10 enters the locking hole 29 from the rear and pushes the locking projection 49 in the locking hole 29 forward. Is elastically displaced to the release posture. At this time, since the front end surface of the release portion 15 stops behind the outer surface (front surface) of the front wall 22, a part (projecting end portion) of the locking protrusion 49 enters the locking hole 29. To be kept. Since the locking allowance between the locking protrusion 49 and the locking hole 29 at this time is smaller than that before the housing 10 is assembled, the locking force between the locking protrusion 49 and the locking hole 29 is reduced. Is lower than the locking force before the housing 10 is assembled. However, with this locking force, the lever 40 can be held in the initial position.

  The lever-type connector 1 is fitted with a mating connector 51 having an upward hood portion 52. When fitting, the electric wire cover 20 is inserted shallowly into the hood part 52 from above, and the cam function part 44 is locked to a cam follower (not shown) formed in the hood part 52. Next, a finger is put on the operation part 41 of the lever 40 to rotate the lever 40 to the fitting completion position side. At this time, an operating force exceeding the locking force between the locking projection 49 and the locking hole 29 is applied to the operation portion 41 or the release operation piece 50 is pushed to move the locking projection 49 from the locking hole 29. When dissociated, the lever 40 starts to rotate.

  In the turning process of the lever 40, the fitting of the lever-type connector 1 and the mating connector 51 proceeds by the cam action by the engagement of the cam function portion 44 and the cam follower. When the lever 40 reaches the mating completion position, both the connectors 1 and 51 reach a proper mating state, and the terminal fitting 12 in the housing 10 and the mating terminal 53 disposed in the hood portion 52. Are connected in a conductive manner. When the lever 40 reaches the mating completion position, the latching protrusion 49 is latched in the lock hole 30, and this latching action causes the lever 40 to be locked at the mating completion position. Is locked in the fitted state.

  As described above, in the present embodiment, the electric wire cover 20 and the lever 40 are engaged with the engaging portion (the engaging hole 29 and the elastic engaging piece for restricting the rotation of the lever 40 in the initial position by engaging with each other. 46) is formed, and only when the housing 10 is correctly attached to the wire cover 20, the locking of the locking hole 29 and the elastic locking piece 46 is released and the lever 40 is rotated. A release portion 15 that allows the

  According to this configuration, when the housing 10 is attached to the wire cover 20, the release portion 15 pushes the locking projection 49, thereby releasing the locking between the locking hole 29 and the elastic locking piece 46. Can be rotated. Further, when the housing 10 is not completely attached to the electric wire cover 20, the locking projection 49 is not pushed by the release portion 15, so that the locking projection 49 and the locking hole 29 are locked with a large locking allowance. The state is maintained, and the lever 40 remains locked in a state where the rotation is restricted. Therefore, the mounting state of the housing 10 with respect to the wire cover 20 can be detected based on whether or not the movement of the lever 40 is allowed.

  Further, the wire cover 20 is formed with a lock hole 30 that holds the lever 40 in the fitting completion position by locking the locking projection 49 of the lever 40 when the lever 40 reaches the fitting completion position. ing. Thus, the locking protrusion 49 (elastic locking piece 46) of the lever 40 also has a function as a locking means for holding the lever 40 in the fitting completion position. In addition to this, the shape of the lever 40 is simplified as compared with the case where a dedicated locking means is formed.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. The lever-type connector 2 according to the second embodiment includes an engaging portion on the electric wire cover 60 (first member which is a constituent element of the present invention), an operating portion 71 of the lever 70, an engaging portion on the lever 70 side, and a housing 65 The release portion 66 of (the second member which is a constituent feature of the present invention) is configured differently from the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  A pair of left and right engaging holes 62 (an engaging portion which is a constituent element of the present invention) penetrates left and right at the front end portions of the left and right side walls 61 of the electric wire cover 60 (from the outer surface to the inner surface of the side wall 61). Form). The front end portions of the left and right outer surface walls of the housing 65 are a pair of left and right release portions 66 for elastically displacing an elastic locking piece 73 described later from the locked posture to the released posture.

  The operation part 71 of the lever 70 does not have a locking means with the locking hole 62. A pair of elastic locking pieces 73 in a form that is bilaterally symmetric and cantilevered toward the operation unit 71 are located at positions near the operation unit 71 in the left and right arm units 72 (which is a constituent requirement of the present invention. (Locking part) is formed. The extending direction of the elastic locking piece 73 is a direction that intersects the rotating direction of the lever 70. A locking projection 74 is formed on the inner surface of the extended end portion of the elastic locking piece 73. In the first embodiment, as the elastic locking piece 46 is elastically displaced, the locking projection 49 is displaced in the direction intersecting the axis of the support shaft 28, whereas in the second embodiment, the elastic locking piece 46 is elastically locked. As the piece 73 is elastically displaced from the locking posture to the releasing posture, the locking protrusion 74 is displaced in a direction substantially parallel to the axis of the support shaft 63.

  A locking surface 75 and a tapered surface 76 are formed on the upper and lower surfaces of the locking projection 74. The locking surface 75 is a plane perpendicular to the rotation direction of the lever 70 and is formed in a region on the base end side of the locking projection 74. The tapered surface 76 is formed in a region on the distal end side of the locking projection 74. The taper surface 76 is not perpendicular to the rotation direction of the lever 70 but is inclined with respect to a plane perpendicular to the rotation direction of the lever 70.

  In a state before the housing 65 is assembled to the wire cover 60, as shown in FIGS. 7 and 13, the lever 70 is engaged by the locking action between the locking surface 75 of the locking projection 74 and the inner surface of the locking hole 62. It is locked in a state where the rotation direction is restricted at the initial position. The inner surface of the locking surface 75 and the locking hole 62 that contacts the locking surface 75 is a surface perpendicular to the rotation direction of the lever 70, so that the lever 70 is reliably restricted from rotating. Moreover, since the latching protrusion 74 and the latching hole 62 are latched in two places on the left and right, the reliability of the latching function is high. At this time, a portion of the locking protrusion 74 on the tip side where the tapered surface 76 is formed penetrates the locking hole 62 and advances into the communication groove. Further, the elastic locking piece 73 of the second embodiment does not have a function for locking the lever 70 at the fitting completion position.

  When the housing 65 is assembled to the electric wire cover 60, as shown in FIG. 11, the left and right release portions 66 abut against the locking projection 74 and push outward in the left-right direction. The formed base end portion is disengaged outward from the locking hole 62. However, as shown in FIG. 14, the tapered surface 76 of the locking projection 74 corresponds to the hole edge of the locking hole 62, and the tapered surface 76 of the locking projection 74 corresponds to the hole of the locking hole 62. When it comes into contact with the edge, the elastic restoring force of the elastic locking piece 73 acts from the locking projection 74 side to the locking hole 62 side to enter a semi-locked state. By this semi-locking action, the lever 70 is held at the initial position.

  Further, since the tapered surface 76 that can contact the hole edge of the locking hole 62 is oblique with respect to the rotation direction of the lever 70, the locking force between the tapered surface 76 and the locking hole 62, that is, this The operating force required to release the lock is smaller than that of the first embodiment. When an operation force in the rotational direction that exceeds the locking force between the taper surface 76 and the locking hole 62 is applied to the lever 70, the taper surface 76 and the hole edge of the locking hole 62 slide and the locking projection 74 is moved. The lever 70 is displaced in the disengagement direction from the locking hole 62, and the lever 70 starts to rotate toward the fitting completion position.

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIGS. The lever-type connector 3 of the third embodiment includes a synthetic resin housing 80 (first member which is a constituent element of the present invention) and a synthetic resin retainer 90 attached to the housing 80 (constituent element of the present invention). A second member), a synthetic resin lever 70 rotatably attached to the housing 80, and an electric wire cover 99 attached to the housing 80.

  The housing 80 as a whole has a small width and a long shape in the front-rear direction. In the housing 80, a plurality of cavities 81 penetrating in the vertical direction are formed side by side in the front-rear direction. A terminal fitting 82 is inserted into each cavity 81 from an opening on the upper surface side of the housing 80. An electric wire 83 is connected to the terminal fitting 82 so as to be conductive, and the electric wire 83 is led out from the upper surface of the housing 80. A pair of left and right communication grooves 84 that extend linearly in the front-rear direction (a direction parallel to the assembly direction of the retainer 90 with respect to the housing 80) and communicate with the cavity 81 are formed inside the housing 80. The communication groove 84 is open to the rear end surface of the housing 80.

  A pair of left and right locking holes 85 (locking portions which are constituent elements of the present invention) are formed in the front end portion of the housing 80 so as to penetrate from the left and right outer surfaces into the communication groove 84. Further, a pair of front and rear positioning holes 86 penetrating into the communication groove 84 from both the left and right outer surfaces are formed in the rear end portion of the housing 80. Further, a pair of support shafts 87 are formed on the left and right outer surfaces of the housing 80. The lever 70 is supported on the support shaft 87 so as to be rotatable between an initial position and a fitting completion position. The basic configuration of the lever 70 including the elastic locking piece 73 (the locking portion which is a constituent element of the present invention) is the same as that of the second embodiment.

  The retainer 90 is made of a synthetic resin and has a plate shape elongated in the front-rear direction. The retainer 90 is formed with a plurality of through holes 91 penetrating in the vertical direction corresponding to the cavities 81. On the inner periphery of each through hole 91, a retaining portion 92 that can be locked to the rectangular tube portion of the terminal fitting 82 is formed to project. The front end portions of the left and right side surfaces of the retainer 90 are a pair of left and right release portions 93. A pair of left and right positioning projections 95 are formed on the left and right side edges at the rear end of the retainer 90.

  When assembling the lever connector 3, first, the lever 70 is attached to the housing 80. The attached lever 70 is locked in a state in which the rotation is restricted at the initial position by the engagement protrusion 74 of the elastic engagement piece 73 engaging the engagement hole 85. A retainer 90 is attached to the housing 80. The attached retainer 90 is held at a temporary locking position (not shown) by locking its positioning projection 95 in the rear positioning hole 86. In a state where the retainer 90 is in the temporary locking position, each through-hole 91 corresponds to the cavity 81, and the retaining portion 92 is located at a position disengaged rearward from the cavity 81. Further, the release portion 93 is located behind the locking protrusion 74 locked in the locking hole 85 and is in a non-contact state with the locking protrusion 74. Therefore, the locking surface 75 and the inner surface of the locking hole 85 come into contact with each other, and the lever 70 is reliably locked at the initial position.

  Thereafter, the terminal fitting 82 is inserted into the housing 80. At this time, since the retaining portion 92 is retracted outside the cavity 81 (that is, the insertion path of the terminal fitting 82), the insertion of the terminal fitting 82 is performed without any trouble. When the insertion of all the terminal fittings 82 is completed, the retainer 90 is pushed forward and moved to the final locking position shown in FIG. Then, the positioning projection 95 is locked in the positioning hole 86 on the front side, so that the retainer 90 is held at the main locking position. Further, since the retaining portion 92 is engaged with the rectangular tube portion 82 a of the terminal fitting 82, the terminal fitting 82 is retained by the retainer 90.

  Further, as the retainer 90 moves to the full locking position, the release portion 93 of the retainer 90 abuts against the locking projection 74 and pushes outward, so that the locking surface 75 of the locking projection 74 is formed. The base end portion is moved outward from the locking hole 85 and the taper surface 76 is brought into a semi-locked state in contact with the edge of the locking hole 85, so that the lever 70 is held at the initial position. The semi-lock structure for holding the lever 70 in the initial position is the same as that of the second embodiment.

After the retainer 90 is attached, the electric wire cover 99 is attached to the housing 80 so as to cover the upper surface (the lead-out surface of the electric wire 83). The electric wire cover 99 has a box shape opened to the lower surface and the rear surface. When the electric wire cover 99 is attached to the housing 80, the electric wire 83 led upward from the housing 80 is bent rearward, and the rear surface of the electric wire cover 99 is obtained. It is led out from the opening of the outside.
Since other configurations are the same as those in the first and second embodiments, description of the structure, operation, and effects is omitted.
