  • Publication number: 20210367371
    Abstract: A connector includes a female housing and a male housing. An arm portion of the female housing engages with an engagement projection of the male housing. In a state where the engagement projection is fitted to an opening of the arm portion, a gap for insertion of a jig exists in the opening at a lateral side of the engagement projection. A groove-shaped release operation portion is formed on the male housing at a lateral side of the engagement projection. An inclined surface is formed at a rear end of the release operation portion, and a wall portion is formed on a rear side of the inclined surface. The arm portion engaged with the engagement projection can be released with a simple operation including inserting the jig into the release operation portion from the gap in the opening and pushing the jig in the same direction as the insertion direction.
