Similarly, the second lever 30B is formed with a cylindrical second engagement protrusion 34B that protrudes from a position that is largely separated from the second support shaft 21B on the lower surface (outer surface) thereof.

  In the state where the second lever 30B is in the initial position, the entrance of the second cam function part 31B opens forward and stands by in preparation for the entry of the second cam follower 11B, and the second engagement protrusion 34B is in the left-right direction. The housing 20 is disposed at a substantially central position, more precisely, a position slightly to the left of the center, and a position that is far away from the second support shaft 21B to the left. The second engagement protrusion 34B is located on the rear end edge of the housing 20 in the front-rear direction.

  Further, on the right side of the second support shaft 21B, the restricting projection 22 is locked from the front with respect to the restricting surface 35 at the rear end of the arc-shaped groove 32 (the holding portion which is a constituent element of the present invention), and the second support is provided. On the left side of the shaft 21B, the holding projection 23 is locked from the front with respect to the holding surface 36 (the holding portion which is a constituent element of the present invention) at the rear end (back end) of the second cam function portion 31B. Rotation of the second lever 30B to the opposite side of the fitting position of the second lever 30B is restricted by the locking action of the restriction protrusion 22 and the restriction surface 35, and the second action is caused by the locking action of the holding protrusion 23 and the holding surface 36. The rotation of the lever 30B toward the fitting position is restricted, whereby the second lever 30B is held in a state where the rotation is restricted at the initial position.

  In addition, since the latching of the holding projection 23 and the holding surface 36 is a semi-lock form, when a turning force exceeding the locking force between the holding projection 23 and the holding surface 36 is applied to the second lever 30B, the second lever 30B.

A groove 46B is formed. The second guide groove 46B penetrates from the outer surface to the inner surface of the lower wall 41B. Also, the lower wall 41B extends to the left from the front end of the second guide groove 46B on the left side, and to the left side from the front end of the second guide groove 46B on the left side. Further, a second approach passage 47B having an L-shaped groove shape that is bent forward and opened to the front end edge of the lower surface wall 41B is formed.

  The right side wall 42 of the operation member 40 is formed with one third guide groove 48 that extends linearly in the front-rear direction (a direction parallel to the movement direction of the operation member 40 relative to the housing 20). The third guide groove 48 penetrates from the outer surface to the inner surface of the right side wall 42.

  The operation member 40 can be moved relative to the housing 20 in the front-rear direction (that is, a direction parallel to the fitting / removing direction of the lever-type connector F and the mating connector M) in a state where it is assembled to the housing 20. It is like that.

Next, the operation of this embodiment will be described.
When assembling the lever-type connector F, first, the terminal fitting is inserted into the housing 20 from the rear with the operation member 40 removed from the housing 20. Then, a plurality of electric wires led out from the rear surface of the housing 20 are collected. On the other hand, the pair of levers 30 </ b> A and 30 </ b> B is held at the initial position by the locking action of the holding surface 36 and the holding protrusion 23 and the locking action of the restriction protrusion 22 and the restriction surface 35.

  Thereafter, the operation member 40 is assembled to the housing 20 from the rear and is engaged with the levers 30A and 30B. At the time of this assembly and engagement, the operating member 40 is moved closer to the housing 20 from the rear with the operation member 40 being shifted slightly to the right with respect to the housing 20 from the normal assembly position. Then, the first engagement protrusion 34A enters the first guide groove 45A, the second engagement protrusion 34B enters the second guide groove 45B, and the left first guide protrusion 24A enters the left first entry path 47A. The left second guide protrusion 24B is caused to enter the left second entry path 47B. The operation member 40 is positioned in the left-right direction with respect to the housing 20 by the engaging action accompanying these entering operations. Further, the front end edge portions of the upper surface wall 41 </ b> A and the lower surface wall 41 </ b> B of the operation member 40 are externally fitted to the rear end edge portion of the housing 20, whereby the operation member 40 is positioned in the vertical direction with respect to the housing 20. At this time, the right side wall 42 of the operation member 40 is positioned so as to be separated to the right with respect to the right side surface of the housing 20.

  Thereafter, the operation member 40 is slightly advanced along the first guide groove 45A, the second guide groove 45B, the first approach path 47A, and the second approach path 47B, and then slid leftward. Then, the first engagement protrusion 34A engages with the first engagement groove 44A in a state where the relative movement in the front-rear direction is restricted, and the second engagement protrusion 34B moves back and forth with respect to the second engagement groove 44B. The pair of first guide protrusions 24A enters the front end portions of the pair of first guide grooves 46A, and the pair of second guide protrusions 24B engages with the pair of second guide grooves. The right third guide protrusion 25R enters the front end of the third guide groove 48.

  After the operation member 40 is assembled to the housing 20 in this way, the front end portion of the housing 20 of the lever-type connector F is shallowly fitted into the hood portion 10 of the mating connector M as shown in FIG. Then, the first cam follower 11A in the hood portion 10 enters the entrance of the first cam function portion 31A, and the second cam follower 11B enters the entrance of the second cam function portion 31B.

  Thereafter, when the operation member 40 is pushed from the rear, the first engagement protrusion 34A is pushed on the inner surface of the first engagement groove 44A as the operation member 40 advances relative to the housing 20. As a result, the first lever 30A starts rotating, and the second lever 30B starts rotating when the second engaging protrusion 34B is pushed by the inner surface of the second engaging groove 44B. Then, with rotation of the lever, the housing 20 is pulled into the hood portion 10 by a boosting action due to the engagement between the cam function portions 31A and 31B and the cam followers 11A and 11B. Then, when both levers 30A and 30B are rotated to the fitting position, as shown in FIG. 7, the lever-type connector F and the mating connector M reach a normal fitting state.

  When the two connectors F and M in the fitted state are detached, the operation member 40 is moved backward. Then, both levers 30A and 30B in the fitting position rotate to the initial position side, and the housing 20 is pulled back from the hood portion 10 by the boosting action due to the engagement between the cam function portions 31A and 31B and the cam followers 11A and 11B. It is. When both levers 30A and 30B reach the initial position, as shown in FIG. 6, the first cam follower 11A reaches the inlet of the first cam function part 31A, and the second cam follower 11B reaches the second cam function part 31B. To reach the entrance. Thereafter, when the lever-type connector F and the mating connector M are pulled apart, the first cam follower 11A is dissociated from the first cam function part 31A, and the second cam follower 11B is dissociated from the second cam function part 31B. Connectors F and M are disconnected.

  Further, in the present embodiment, the operation member 40 can be assembled to the housing 20 in a posture in which the operation member 40 is reversed left and right, and the bundle of electric wires can be led out to the right. In this case, the operating member 40 is made to approach from the rear with the housing 20 being shifted to the left, and the first engagement protrusion 34A is engaged with the second engagement groove 44B via the second guide groove 45B. The second engagement protrusion 34B is engaged with the first engagement groove 44A via the first guide groove 45A, the first guide protrusion 24A enters the second guide groove 46B, and the second guide protrusion 24B is One guide groove 46A is entered. Further, the third guide protrusion 25 </ b> L on the left side of the housing 20 enters the third guide groove 48. Also in this case, when the operation member 40 is moved forward, both the levers 30A and 30B held at the initial position can be turned to the fitting position side, and both the connectors F and M can be fitted.

  As described above, when the operation member 40 is removed from the housing 20, the levers 30 </ b> A and 30 </ b> B are engaged by the engaging action of the holding protrusion 23 and the holding face 36 and the engaging action of the restricting protrusion 22 and the restricting face 35. Is held in the rotation restricted state, so that when the operating member 40 is assembled to the housing 20, the engaging grooves 44A and 44B of the operating member 40 are engaged with the engaging protrusions 34A and 34B of the levers 30A and 30B. Easy and excellent workability.

  In the present embodiment, the levers 30A and 30B whose rotation is restricted are in the initial positions, that is, when the housing 20 is shallowly fitted to the mating connector M, the cam function portions 31A and 31B are engaged with the cam followers 11A and 11B. It is designed to be held in a position where it can be matched. Therefore, the operation of the operation member 40 for displacing the levers 30A and 30B to the initial position is not required after the operation member 40 is assembled to the housing 20 until the mating connector M is fitted. Is also excellent in workability.

  Further, since the holding surfaces 36 of the levers 30A and 30B are formed in the cam function portions 31A and 31B, the shape of the levers 30A and 30B is compared to the case where the holding surface 36 is provided separately from the cam function portions 31A and 31B. Simplification is realized.

  The operating member 40 is formed with a plurality of first guide grooves 46A and second guide grooves 46B extending in the front-rear direction at intervals in the left-right direction intersecting the moving direction of the operating member 40. A plurality of first guide protrusions 24A and second guide protrusions 24B that can be engaged with the first guide grooves 46A and the second guide grooves 46B are formed on the outer surface. When the operation member 40 assembled to the housing 20 is moved in the front-rear direction due to the engagement of the plurality of guide grooves 4A, 46B and the guide protrusions 24A, 24B, the posture of the operation member 40 with respect to the housing 20 is stabilized. So it has excellent operability.

  Further, when the operating member 40 is assembled to the housing 20, the engaging protrusions 24A and 24B function as positioning means by fitting the guide grooves 47A and 47B into the engaging protrusions 24A and 24B. The member 40 can be positioned with respect to the housing 20. Since the guide grooves 47A and 47B are opened at the front end edge of the operation member 40, the engagement protrusions 24A and 24B can be guided into the engagement grooves 44A and 44B without deforming the operation member 40. Therefore, it is excellent in workability.
