A terminal metal fitting () includes a tubular box portion () receiving a counterpart terminal; a lock hole () formed through a wall () of the box portion () and receiving the lock projection (); a terminal spring () extending from an inner wall surface of the box portion () to press and contact to the counterpart terminal; and a supporting point portion () formed at a portion around the lock hole () to have a cantilevered-shape. The supporting point portion () serves as a supporting point () when the terminal spring () contacts to the counterpart terminal.

Terminal metal fitting and engagement structure of terminal metal fitting and housing

A terminal metal fitting includes a tubular box portion receiving a counterpart terminal; a terminal spring extending from an inner wall surface of the box portion to press and contact the counterpart terminal; and a deformation restriction portion restricting deformation of the terminal spring within a preset range when the terminal spring contacts the counterpart terminal. The deformation restriction portion has a chamfered portion to contact the terminal spring.

Terminal metal fitting with spring contact and spring contact deformation restriction portion

In a terminal accommodating chamber provided in a housing of a connector, a terminal to which an electric wire is connected is accommodated. The terminal is held by the engagement between a locking face of a lance molded in a terminal accommodating chamber and a locking target face provided in a box portion of the terminal. The locking target face is provided in a front ceiling plate molded by notching a ceiling plate of the box portion in a width direction to reach a facing plate outer face. The locking face and the locking target face are engaged with each other within a range wider than a facing plate inner face width of the facing plate.

Electrical connector with housing having a lance engaging a box terminal

A connector includes a terminal including an electric contact portion having a lock end edge at a rear end thereof in an insertion direction and a wire connection portion having a core wire caulked portion; a housing having an insertion opening on a rear end surface thereof and a terminal accommodation chamber to accommodate the terminal inserted from the insertion opening; a flexible lock piece integrally formed with the housing and having a lock surface locking the lock end edge of the terminal inserted into the terminal accommodation chamber; an inclined surface formed on the flexible lock piece, pressed by the terminal during insertion, and moving the lock surface in an unlocking direction; and a recessed clearance portion formed on the inclined surface and having a bottom surface located farther from the core wire caulked portion of the insertion-completed terminal and the vicinity thereof than the inclined surface.

Connector with flexible lock piece

A terminal includes a box, the box of the terminal connected to an electric wire includes a ceiling plate and an inner plate. The ceiling plate includes a front ceiling plate and a rear ceiling plate formed by a notch. The rear ceiling plate includes a projection part engagement surface provided by the forming of the notch. The inner plate includes a projection part. In a state where the ceiling plate and the inner plate are superimposed, the projection part and the projection part engagement surface are engaged with each other.

Terminal and connector

A connector includes a housing that holds a plurality of terminals and a mating housing that holds a plurality of mating terminals to be connected to the terminals. The mating housing is fitted into the housing to connect the mating terminals to the terminals. The housing comprises a partition wall portion which projects ahead of the terminals and separates adjacent ones of the terminals from each other.

Connector

A connector, for being joined to a mating connector, includes a housing. The housing includes a housing main body and a lock arm with an engagement protrusion. The housing main body is formed with a terminal accommodation chamber configured to accommodate a terminal and extending along a joining direction in which the connector is joined to the mating connector. The lock arm extends from a front end side of the housing main body to a rear end side of the housing main body along the joining direction. The lock arm is connected integrally with the front end side of the housing main body. The housing main body is formed with a through hole which extends along the joining direction and is disposed at a connecting part of the housing main body where the lock arm is connected to the housing main body.

Connector having a housing with a lock arm

A connector includes a terminal, a housing body haying a terminal housing chamber inside which the terminal is housed, an opening portion formed at an outer peripheral surface of the housing body, a retainer having a locking protrusion that protrudes into the terminal housing chamber to lock the terminal housed in the terminal housing chamber when the retainer is fitted to the opening portion, and a hinge that connects the retainer to the housing body so as to allow the retainer to turn between an open position at which the opening portion is opened and a closed position at which the retainer is fitted to the opening portion to close the opening portion. When the retainer is in the closed position, an outer surface of the retainer is flush with the outer peripheral surface of the housing body.
