Abstract

The lever-type connector includes a first housing, a housing fitted to and removed from the first housing, and a lever turnably supported by the housing, where the lever is configured to fit the both housings. The lever includes a provisional lock arm portion having a provisional locking portion, and the housing includes a provisional locked portion configured to be provisionally fitted to and detached from the provisional locking portion of the provisional lock arm portion and a provisional set arm portion configured to suppress detachment between the first housing and the housing in the provisionally set state during the provisional lock release of the lever. The first housing includes a release rib portion configured to release the provisional locking state between the provisional locking portion of the provisional lock arm portion and the provisional locked portion of the housing.

First claim

What is claimed is:

1. A lever-type connector comprising:
a first housing having a cam boss;
a second housing fitted to and removed from the first housing; and
a lever turnably supported by the second housing via a support shaft, the lever having a cam groove engaging with the cam boss, the lever configured to pull the first housing toward the second housing to fit the first housing and the second housing by engagement between the cam groove and the cam boss through a turning operation from a provisional locking position to a fitting completion position, wherein
the lever includes a provisional lock arm portion having a provisional locking portion, the provisional lock arm portion being elastically deformed,
the second housing includes a provisional locked portion configured to be provisionally locked to and detached from the provisional locking portion of the provisional lock arm portion and a provisional set arm portion configured to suppress detachment between the first housing and the second housing in a provisionally set state during a provisional lock release between the provisional locking portion of the provisional lock arm portion and the provisional locked portion of the second housing, and
the first housing includes a release rib portion configured to release a provisional locking state between the provisional locking portion of the provisional lock arm portion and the provisional locked portion of the second housing.

2. The lever-type connector according to claim 1 , wherein
a provisional set beak portion is provided on a lower face of the release rib portion,
a protrusion portion configured to slide along the lower face of the release rib portion is provided at a distal end of the provisional set arm portion, and
a provisional locking state of the lever is released at a position where the protrusion portion goes over the provisional set beak portion from the lower face of the release rib portion.

3. The lever-type connector according to claim 2 , wherein
the provisional set beak portion has a trapezoidal shape, and is projected integrally with the release rib portion.

4. The lever-type connector according to claim 2 , wherein
a distal end of the release rib portion functions as a release portion to release a provisional locking state between the provisional locked portion of the second housing and the provisional lock arm portion of the lever.
