A connector structure () includes a first connector () and a second connector (). The outer housing () of the first connector () has: a lock mechanism () to be engaged with a counterpart housing () of the second connector () to restrict a rearward movement of the counterpart housing () in the fitting direction when fitting the first connector () and the second connector (); a first unlocking mechanism () configured to disengage a lock mechanism () for the counterpart housing (); and a second unlocking mechanism () located at a different position than the first unlocking mechanism () and configured to disengage the lock mechanism () independently of the first unlocking mechanism ().

Connector structure with multiple disengagement mechanisms

A water stop member of a crimp terminal is affixed to an inner wall surface of an electric wire connecting portion of a terminal fitting before crimping and forms into a first water stop area, a second water stop area, and a third water stop area after the crimping. The first water stop area suppresses entering of water from a space between the outer wall surface of a first barrel piece and the inner wall surface of a second barrel piece in the electric wire connecting portion. The second water stop area suppresses entering of water from the side closer to a terminal connecting portion of the terminal fitting than the distal end position of a core wire. The third water stop area suppresses entering of water from a space between the inner wall surface of a cover crimping portion of the electric wire connecting portion and a cover.

Crimp terminal

A crimp terminal includes: a terminal fitting having a terminal connecting portion electrically connected to a counterpart terminal and an electric wire connecting portion electrically connected by crimping to an end portion of an electric wire placed on an inner wall surface thereof; and a second water stop portion that is pasted on the inner wall surface of the electric wire connecting portion before crimping and that, after crimping, forms a second water stop area capable of suppressing water entry between the electric wire connecting portion and the core wire from the terminal connecting portion side with respect to the distal end position of the core wire at the distal end of the electric wire. The electric wire connecting portion has a core wire crimp portion crimped on the core wire at the distal end of the electric wire.

A water stop member of a crimp terminal is affixed to the inner wall surface of an electric wire connecting portion of a terminal fitting before crimping and forms into a first water stop area, a second water stop area, and a third water stop area after the crimping. The first water stop area suppresses entering of water from a space between the outer wall surface of a first barrel piece and the inner wall surface of a second barrel piece in the electric wire connecting portion. The second water stop area suppresses entering of water from the side closer to a terminal connecting portion of the terminal fitting than the distal end position of a core wire. The third water stop area suppresses entering of water from a space between the inner wall surface of a cover crimping portion of the electric wire connecting portion and a cover.

A terminal fitting includes a terminal connecting portion and an electric wire connecting portion. A water stop member is affixed to an inner wall surface of the electric wire connecting portion before crimping process and suppresses entering of water between the electric wire connecting portion and a core wire of the electric wire after the crimping. The electric wire connecting portion is formed into a U-shape by raising the first barrel piece and the second barrel piece from both ends of the bottom. The distal end of the first barrel piece is bent toward the second barrel piece, to form a gap between a slide contact surface on a descending second die and the distal end of the first barrel piece.

Crimp terminal and terminal crimping device

A crimp terminal includes a terminal connecting portion and an electric wire connecting portion. The electric wire connecting portion is sectioned into a bottom portion, a first barrel piece, and a second barrel piece, and is sectioned into a core wire crimp portion, a sheath crimp portion, and a coupling crimp portion. A water stop member affixed to the inner wall face of the electric wire connecting portion before crimping processing forms a first water stop area, that suppresses the entry of water, from the gap between the outer wall face of the first barrel piece and the inner wall face of the second barrel piece, a second water stop area from the terminal connecting portion side of the distal end position of a core wire, and a third water stop area from the gap between the inner wall face of the sheath crimp portion and a sheath.
