A lever insertion hole () for inserting a lever () is provided in a female housing (). A rib () and a flexible lever-holding lock () are arranged on the inner wall (A) of the lever insertion hole (). The rib () enables the lever () to be inserted, through a key groove () axially provided in the outer peripheral surface of the lever (), into the female housing () only when the lever () is at a predetermined rotational position. The rib () and the lever-holding lock () are together in contact with a wall section () of a coming-out prevention groove (), provided in the lever (), to hold the lever () from coming out.

Lever-fitting type connector with rotatably insertable locking lever

A waterproof connector, comprising a pair of male and female housings () engaged with each other. The waterproof connector also comprises a grommet () covering at least one of the housings () and a fastening member () inserted from the grommet () side into the pair of male and female housings () to connect them to each other. In addition, the grommet comprises a sealing part () having a predetermined length along the inserting direction of the fastening member () and formed integrally with a grommet body () at the outlet side end part () thereof.

Waterproof connector

A through-panel connector, comprising a female connector () and a male connector disposed on one side and the other side of panel () and fitted to each other through a mounting hole () formed in the panel (). The female connector () comprises a plurality of flexible holding ribs (). The holding ribs () are formed on the outer peripheral surface () of the female connector () opposed to the mounting hole inner peripheral surface () of the panel () so as to be extended along the inserting direction of the mounting hole () and separated from the outer peripheral surface () while being extended from the base end part () to the tip part () of the female connector () along the mounting hole inner peripheral surface (). The holding ribs () are biased and held on the mounting hole inner peripheral surface () with the female connector () fitted to the panel ().

Through-panel connector

A lever-fit connector, wherein a rotation prevention lock () preventing a lever () from being rotated when male and female connector housing are fitted (joined) to each other is installed in the inner wall (A) of a lever insert hole () in a female housing (). A rotation lock recessed part () in which the rotation lock part (D) of the rotation prevention lock () is engageably stored is formed in the peripheral surface of the lever (). The angle of the rotation lock part (D) is set so that the rotation lock part (D) is drawn to the lever () side in excessive rotation by bringing the rotation lock part (D) into contact with the side wall surface (B) of the rotation lock recessed part ().

Lever-fitting type connector

According to a connector engaging structure of this invention, first add second connectors are mutually fitted to with each other of separated from each other by pivoting an operation lever. The operation lever is pivotably supported by a housing of the first connector through a supporting shaft. An engaging protrusion is provided on a front face of the housing. An engaging hole for engaging with or disengaging from the engaging protrusion is provided on a first side wall of the operation lever opposing the engaging protrusion. A gap is formed between a rear face of the housing and a second side wall of the operation lever. When the second side wall of the operation lever is moved toward the rear face of the housing so that the gap is reduced, the engaging state between the engaging protrusion and engaging hole can be released. Therefore, it is possible to prevent an error releasing of the engagement of the operation lever with such a simple structure and release the operation lever engaging state easily when it is necessary.
