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 water-stop structure () for a connector has: a terminal () including a mating terminal connecting portion (), a wire barrel portion (), and an insulation barrel portion (); an electric wire () installed on the terminal () in such a manner that a sheath () is removed to expose a core wire () at one end portion, the exposed core wire () is held by the wire barrel portion (), and a portion of the sheath () near the exposed core wire () is held by the insulation barrel portion (); and a sealing body () integrally provided on the electric wire () and the terminal () so as to cover at least the insulation barrel portion ().

Water-stop structure for connector

A leaf spring portion turning back at a bottom wall (first side wall portion) and coming into contact with a male terminal of a connector on the other side to press the male terminal to a ceiling wall (second side wall portion) is formed in a tubular-shaped main terminal body portion in a terminal, the main terminal body portion is formed when a metal plate is bent in a tubular shape such that a pair of end edges approaches each other to form the ceiling wall (second side wall portion), and depressed portions bending toward an inside of the main terminal body portion and extending in a longitudinal direction of the main terminal body portion are provided in a pair of respective wall portions forming the ceiling wall (second side wall portion).

A receptacle connector includes: a shielding case; an insulator accommodated in the shielding case; and a first contact arranged on a terminal supporting part of the insulator. A clearance is provided between a tip of the terminal supporting part of the insulator and a tip of the first contact. The tip of the terminal supporting part has an inclined surface to provide the clearance.

Receptacle connector

A connecting terminal has a tubular part into which a mating terminal is to be inserted and a spring contact part extended from the tubular part and arranged in the tubular part, wherein insertion of the mating terminal into the tubular part is allowed by elastic deformation of the spring contact part and the mating terminal inserted into the tubular part is to be electrically connected with the connecting terminal using an elastic restoring force of the spring contact part as a contact load, and the connecting terminal has auxiliary spring parts extended from the tubular part and elastically deformed following elastic deformation of the spring contact part.

Connecting terminal

There is provided a shielded connector that can prevent collapse of a cantilever wall in a housing while pursing a lower profile. A shielded connector has a tubular inner shell that covers terminals for connection with another connector; an outer shell that covers the inner shell; and a housing for retaining the inner shell in the outer shell. The outer housing has receiving grooves formed in an indented manner in free-end side walls of a cantilever wall that extends along an interior wall of the outer shell in a direction of insertion of the connector and that has a lock receiving portion to engage with a lock portion of another connector. The outer shell has, in upper portions of respective leading-side side walls, supporting projections to engage with the receiving grooves of the cantilever wall.
