Abstract: A connector includes a terminal having a base plate portion and a pair of elastic curl portions, a connector housing having a terminal accommodating chamber, a flexible locking piece provided on a first wall of facing walls of the terminal accommodating chamber, a recessed groove provided on a second wall of the facing walls, extends from a rear side of the connector housing toward a front side of the connector housing along a terminal insertion direction of the terminal, and has a groove width smaller than a width of the base plate portion, and a contact surface formed at a front end portion of the recessed groove. When the terminal is reversely inserted, tip end contact portions of the elastic curl portions are brought into contact with the contact surface to prevent the terminal from being inserted further.

Abstract: In a connector (4) including: a first connector housing (5) including a hood portion (52) having a substantially cylinder shape to be fitted to an outer circumference of a cylindrical portion (82) of a second connector housing (8), and a lock arm (53) formed integrally with a terminal storing portion (51) such that a free end side of the lock arm (53) is deflected and deformed in a direction perpendicular to a surface of the cylindrical portion (82); and the second connector housing (8) including the cylindrical portion (82), and a lock protrusion (83) which is provided to protrude from an outer surface of the cylindrical portion (82) and which engages the lock arm (53) when a fitting length between the cylindrical portion (82) and the hood portion (52) reaches a predetermined value, the first connector housing (5) is formed of a hydrolysis-resistant material.

Abstract: A connector includes a first member constituting a main body of the connector; and one or a plurality of second members attached to the first member. A specific member is selected from the group consisting of the first member and the second members to have a portion to be elastically deformed upon the attachment, and the specific member is formed of a hydrolysis-resistant material.

Abstract: A connector includes: a first connector housing which allows a second connector housing to be fitted in a fitting direction; and a retainer which is inserted, in an insertion direction perpendicular to the fitting direction, into the first connector housing, and which includes: a housing lock arm engaged with a lock protrusion provided in the first connector housing to position the retainer in a temporary lock position and a regular lock position when the retainer is inserted into the first connector housing; and a terminal lock portion engaged with a terminal metal fitting provided in the first connector housing to prevent the terminal metal fitting from dropping off when the retainer is positioned in the regular lock position. The retainer includes an arm support portion which supports both ends of the housing lock arm extending in the insertion direction.

Abstract: To provide a press-fit terminal and a terminal press-fit structure that enable shortening of a press-fit portion in its longitudinal direction and miniaturization of a connector. A press-fit terminal has insertion stoppers that are projectingly provided on respective flanks of a press-fit portion and that have respective engagement surfaces oriented orthogonally to a press-fit direction; and holding projections that are projectingly provided on respective protruding leading-end faces of the insertion stoppers and that bite into interior side walls of a press-fit hole of a housing which receives the press-fit portion. Each of the holding projections is projectingly formed in a portion of the protruding leading-end face of the insertion stopper along its thicknesswise direction.
