Abstract

A lever-type connector includes a mating housing having a cam boss and a release rib portion, a housing that has a support shaft and a temporarily locked portion and that is fitted into and removed from the mating housing, and a lever having a temporary locking arm portion where a temporary locking portion is temporarily locked to the temporarily locked portion and is unlocked from the temporarily locked portion by the release rib portion, the lever having a cam groove including a boss pick-up portion and a boss holding portion that engage with the cam boss, and the lever being rotated from a temporary locking position to a fitting completion position via the support shaft to cause the cam groove to engage with the cam boss, thus moving the mating housing toward the housing and fitting the mating housing and the housing to each other.

First claim

What is claimed is:

1. A lever-type connector comprising:
a mating housing having a cam boss;
a housing that is fitted into and removed from the mating housing; and
a lever that is rotatably supported by the housing via a support shaft, has a cam groove engaging with the cam boss, and is rotated from a temporary locking position to cause the cam groove to engage with the cam boss, thus moving the mating housing toward the housing and fitting the mating housing and the housing to each other, wherein
the lever includes a temporary locking arm portion that has a temporary locking portion and is elastically deformable and configured to apply a force inward towards a center of the housing,
the housing includes a temporarily locked portion that is temporarily locked to and unlocked from the temporary locking portion of the temporary locking arm portion,
the mating housing includes a release rib portion that releases a temporary locking state of the temporary locking portion of the temporary locking arm portion and the temporarily locked portion of the housing, and
the cam groove of the lever includes a boss pick-up portion and a boss holding portion that engage with the cam boss,
wherein, at an opening of the cam groove, a tip end of the boss holding portion faces a step of the boss pick-up portion in the cam groove and between a part of the boss pick-up portion extended from the opening to the step and an inner portion of the boss pick-up portion extended from the step and away from the opening, and
the boss holding portion is configured to hold the cam boss in a state where the mating housing and the housing are temporarily set, and
wherein the cam groove of the lever includes a boss receiving portion that receives the cam boss when the temporary locking state of the temporary locking portion of the temporary locking arm portion and the temporarily locked portion of the housing is released in a state where the mating housing and the housing are temporarily set.

2. The lever type connector according to claim 1 ,
wherein the temporary locking arm portion is further configured to apply a force inward towards the center of the housing along a track of the mating housing.

3. A lever-type connector comprising:
a mating housing having a cam boss;
a housing that is fitted into and removed from the mating housing; and
a lever that is rotatably supported by the housing via a support shaft, has a cam groove engaging with the cam boss, and is rotated from a temporary locking position to cause the cam groove to engage with the cam boss, thus moving the mating housing toward the housing and fitting the mating housing and the housing to each other, wherein
the lever includes a temporary locking arm portion that has a temporary locking portion and is elastically deformable and configured to apply a force inward towards a center of the housing,
the housing includes a temporarily locked portion that is temporarily locked to and unlocked from the temporary locking portion of the temporary locking arm portion,
the mating housing includes a release rib portion that releases a temporary locking state of the temporary locking portion of the temporary locking arm portion and the temporarily locked portion of the housing, and
the cam groove of the lever includes a boss pick-up portion and a boss holding portion that engage with the cam boss,
wherein the boss holding portion faces the boss pick-up portion in the cam groove, and
the boss holding portion is configured to hold the cam boss in a state where the mating housing and the housing are temporarily set,
wherein the cam groove of the lever includes a boss receiving portion that receives the cam boss when the temporary locking state of the temporary locking portion of the temporary locking arm portion and the temporarily locked portion of the housing is released in a state where the mating housing and the housing are temporarily set, and
wherein the temporary locking arm portion is further configured to apply a force inward towards the center of the housing along a track of the mating housing.
