As shown in fig. 3, the lever member 18 has:

arm portions

36, 36 disposed on both sides; and an operation portion 38 for connecting the

arm portions

36, 36. The

arm portions

36, 36 are formed with rotation support holes 40, 40. Rotation shafts 42 and 42 (shown in fig. 1 and 2) formed to protrude from the side surface of the 1 st housing 16 are fitted into the rotation support holes 40 and 40. The rod member 18 is supported movably with respect to the 1 st housing 16 through the rotation support holes 40 and the

rotation shafts

42 and 42, and is supported rotatably in this embodiment.

Further, in the lever member 18, locking

fitting portions

44, 44 are formed at the end portions of the

arm portions

36, 36 on the side opposite to the operation portion. In this embodiment, the locking

fitting portions

44 and 44 are configured such that a concave portion is formed between 2 convex portions. The locking

engagement portions

44 and 44 are engaged with locking engagement receiving portions 46 and 46 (shown in fig. 1 and 2) formed in the 2 nd housing 30a so as to protrude outward in a semi-cylindrical shape, and the 1 st housing 16 and the 2 nd housing 30a are locked by the lever member 18.

The lever member 18 is provided with lock

auxiliary portions

48, 48 extending downward from the root portions of the

arm portions

36, 36. In this embodiment, lock assist

projections

50, 50 are formed at the ends of the lock assist

portions

48, 48 so as to project toward the 1 st housing 16 side. On the other hand, as shown in fig. 4A and 4B,

pre-lock holes

52 and 52, which are engagement portions, are formed in the 1 st case 16, and the lock

auxiliary projections

50 and 50 are engaged with the

pre-lock holes

52 and 52 at the pre-lock position.

The pre-lock means that the lever member 18 is stably held in the 1 st housing 16 before the 1 st connector member 12 and the 2 nd connector member 14 are locked.

Furthermore,

pre-lock releasing grooves

54, 54 are formed inside the side surface of the 1 st housing 16. The

pre-lock release grooves

54, 54 are formed in parallel to the direction of insertion of the 2 nd connector component 14 through the pre-lock holes 52, 52. On the other hand, pre-lock releasing projections 56, 56 (shown in fig. 1, 2, and 5) are formed on the side surface of the 2 nd housing 30a of the 2 nd connector component 14. The

pre-lock release projections

56, 56 are formed parallel to the insertion direction of the 2 nd connector component 14 corresponding to the

pre-lock release grooves

54, 54. As shown in fig. 5, when the 2 nd housing 30a is inserted into the 1 st housing 16, the preliminary

lock releasing projections

56, 56 are fitted into the preliminary lock releasing grooves 54, and when the 2 nd housing is continuously inserted into the 1 st housing 16, the distal ends of the preliminary

lock releasing projections

56, 56 come into contact with the lock

auxiliary projections

50, 50 of the lever member 18, and when the 2 nd housing is further inserted into the 1 st housing 16, the lock

auxiliary portions

48, 48 are pushed outward against the elasticity of the lock

auxiliary portions

48, 48 of the lever member 18, and by rotating the lever member 18, the engagement between the preliminary

lock releasing holes

52, 52 and the lock

auxiliary projections

50, 50 is released, thereby releasing the preliminary lock.

In addition, the 1 st inclined

portions

58, 58 are formed on the lock auxiliary projections 50, the 2 nd inclined

portions

60, 60 are formed on the preliminary lock releasing projections 56, and the engagement between the preliminary

lock releasing projections

56, 56 and the lock

auxiliary projections

50, 50 is easily released by the 1 st inclined

portions

58, 58 and the 2 nd inclined

portions

60, 60.

As described above, when the preliminary locking of the lever member 18 is released, the

lock assisting projections

50, 50 of the

lock assisting portions

48, 48 sandwich the side surface of the 1 st case 16 from both sides, and the

lock assisting projections

50, 50 of the lever member 18 can slide along the side surface of the 1 st case 16 and rotate to the lock position with contact pressure.

In the locked position, the locking

fitting portions

44, 44 are exposed to the 2 nd housing 30a side through the locking holes 64, 64 (shown in fig. 4B) formed in the 1 st housing 16, the locking

fitting portions

44, 44 are fitted to the locking fitted

portions

46, 46 of the 2 nd housing 30a, and the 1 st housing 16 and the 2 nd housing 30a are in the locked state.

The

lock assisting projections

50, 50 of the

lock assisting portions

48, 48 draw arcs around the

rotation shafts

42, 42. As shown in fig. 6, on the side surface of the 1 st case 16, 3 rd inclined

portions

68, 68 are formed at positions of the lock guide holes 66, that is, at portions near the lock positions. The 3 rd inclined

portions

68, 68 are inclined such that the contact pressure between the

lock assisting protrusions

50, 50 and the 1 st housing 16 gradually decreases toward the rotational direction of the lever member 18 to the lock position. Therefore, a force in the rotational direction toward the lock position acts on the lever member 18 as a component of the contact pressure with the 1 st housing 16, and the force for moving the lever member 18 to the lock position can be reduced, and the fitting between the 1 st connector component 12 and the 2 nd connector component 14 can be assisted.

In this embodiment, the 4 th inclined

parts

70, 70 are formed on the lock assisting projections 50, and the 4 th inclined

parts

70, 70 are in contact with the 3 rd inclined

parts

68, 68.

In addition, the inclined portion may be formed on at least one of the lock assisting portions 48 and the 1 st case 16.

Next, an operation of fitting the 1 st connector component 12 and the 2 nd connector component 14 will be described with reference to fig. 7A to 10C.

Fig. 7A, 7B, and 7C show the first state of fitting between the 1 st connector component 12 and the 2 nd connector component 14. The lock

auxiliary projections

50, 50 of the lever member 18 are engaged with the preliminary lock holes 52, 52 of the 1 st housing 16, and a preliminary lock state is achieved. The

guide projections

34 and 34 of the 2 nd housing 30a are inserted into the guide holes 24 of the 1 st housing 16, are guided, and are inserted into the 1 st housing 16. The

pre-lock release projections

56, 56 of the 2 nd housing 30a are also inserted into the

pre-lock release grooves

54, 54 of the 1 st housing 16.

When the 2 nd housing 30a is further inserted into the 1 st housing 16, as shown in fig. 7B, the distal ends of the preliminary

lock release projections

56, 56 abut against the lock

auxiliary projections

50, 50.

Fig. 8A, 8B, and 8C show a state in which the pre-lock is released.

When the 2 nd housing 30a is further inserted into the 1 st housing 16 from the state shown in fig. 7A, 7B, and 7C, the preliminary

lock releasing projections

56, 56 press the lock assisting projections 50, and the

lock assisting portions

48, 48 are pushed open outward against the elasticity of the

lock assisting portions

48, 48. When the lever member 18 is slightly rotated clockwise from this state, the

lock assisting projections

50, 50 are disengaged from the preliminary locking holes 52, and the preliminary locking is released. When the preliminary lock is released, the

lock assisting projections

50, 50 come into contact with the side surface of the 1 st housing 16, and the lever member 18 can be rotated while the

lock assisting portions

48, 48 are pressed against the 1 st housing 16.

Fig. 9A, 9B, and 9C show the state just before the lock position.

When the 2 nd housing 30a is continuously inserted into the 1 st housing 16 while the lever member 18 is rotated, the

lock assisting projections

50, 50 of the lever member 18 are caught on the 3 rd inclined

portions

68, 68. Since the 3 rd inclined

portions

68 and 68 are inclined such that the contact pressure between the lock assisting projections 50 and the 1 st housing 16 gradually decreases in the rotational direction of the lever member 18 to the lock position, a force in the rotational direction to the lock position acts on the lever member 18 as a component of the contact pressure with the 1 st housing 16, and a force for moving the lever member 18 to the lock position can be reduced, and the fitting between the 1 st connector member 12 and the 2 nd connector member 14 can be assisted.

Fig. 10A, 10B, and 10C show the state in the lock position.

The

lock assisting projections

50, 50 of the lever member 18 are separated from the 3 rd inclined

parts

68, 68 and come into contact with the side surface of the 2 nd housing 30 a. The locking

fitting portions

44, 44 are exposed to the 2 nd housing 30a side, the locking

fitting portions

44, 44 are fitted to the locking fitted

portions

46, 46 of the 2 nd housing 30a, and the 1 st housing 16 and the 2 nd housing 30a are locked by the lever member 18.
