A connector includes: a terminal fitting; a housing containing the terminal fitting inside and provided with a fitting portion inserted and fitted into inside of a hole-shaped counterpart fitting portion of a counterpart wall member; and a shield shell including a cylindrical portion covering, from outside, a projecting portion of the housing projecting from the counterpart fitting portion, a flange portion projecting outer than an outer circumferential surface of the cylindrical portion and a fixed portion bent from an end portion of the flange portion and fixed on an end surface of the counterpart wall member. The shield shell is provided with a bent portion between the flange portion and the fixed portion, and a bulging portion including an inner wall surface positioned inside a curve of the bent portion at an end portion in an extending direction of a bending line of the bent portion.

A connector includes: a terminal fitting; a housing containing the terminal fitting inside and provided with a fitting portion inserted and fitted into inside of a hole-shaped counterpart fitting portion of a counterpart wall member; a shield shell including a cylindrical portion covering, from outside, a projecting portion of the housing, a flange portion projecting outer than an outer circumferential surface of the cylindrical portion, and a fixed portion bent from an end portion of the flange portion and fixed on an end surface of the counterpart wall member; and an annular water stop member attached to the flange portion and pressed between the flange portion and the wall surface of the counterpart wall member. The shield shell is provided with a through hole provided in a bent portion between the flange portion and the fixed portion and causing inside and outside thereof to communicate with each other.

Connector

A connector includes: a terminal metal fitting that is connected to an electric wire and is configured to be inserted into a connector insertion hole of a metal case of a counterpart device from an opening; a housing includes a connector insertion part configured to be inserted into the connector insertion hole from the opening together with the terminal metal fitting; a liquid seal member that is configured to seal a gap between the housing and a rim of the opening in the case; a shield shell that includes a cylindrical accommodation body accommodating the housing therein, an annular flange configured to be opposed to an annular surface around the rim of the opening in the case, and a fixed part configured to be fixed to the case; and an annular interposed member that is configured to be interposed between the flange and the annular surface to be sandwiched therebetween.

Electrical connector with shield shell for connecting to case

Provided is a packing arrangement structure which can prevent rotation of a packing. The packing arrangement structure includes an annular packing disposed between a first member and a second member. The packing includes an annular portion main body extending in an axial direction of the packing and a protruding portion protruding from the annular portion main body in an outward direction or in an inward direction. The first member is provided with a recessed portion configured to house the protruding portion and formed into a shape corresponding to the protruding portion. The protruding portion is formed such that a circumferential dimension of a top portion thereof located in a protruding direction is greater than a circumferential dimension between basal parts thereof.

Packing arrangement structure

A shield connector includes an outer housing accommodating a shield shell in a shell insertion direction. A stepped part protrudes from an inner wall of the outer housing to support the shield shell. A cover plate portion of the shield shell includes a bendable side portion extending along the shell insertion direction. A tip imaginary line of an end face of the stepped part is curved so that a position of the end face corresponding to the joining portion is located on a far side from an electric wire pullout opening in the shell insertion direction than a position of the end face corresponding to the bendable side portion, to thereby urge the cover plate portion in a bending direction when an inner housing with the shield shell is inserted into the outer housing.

Shield connector

A connector unit which prevents a user from contacting a first terminal fitting when fitting a first connector and a second connector together is provided. A connector unitincludes a first connectorhaving a first housingreceiving a first terminal fittingand a contact-preventive housingdisposed between the first terminal fitting and the first housing, and a second housing to be fitted to the first housing. The contact-preventive housing includes a tension springhaving one end fixed at an outer circumference of the contact-preventive housing and the other end being a free-end arranged to engage to the first housing to restrict the contact-preventive housing from sliding. The second housing includes an entering portionwhich enters between the tension spring and the first housing and pushes the tension spring to disengage the tension spring to permit the contact-preventive housing to slide.

Connector unit

For connection and disconnection of both connectors with ease and assurance in a narrow work space and connection, and for disconnection of a safety circuit unit without mistakes and in a saved-space, a low-insertion-force connector assemblyis provided with one connector receiving the one terminal and other connectorreceiving a mating terminal, wherein the one connector includes a driving leverhaving a rotative circular-arc-shaped gear part, and, pivotally supported along a wall partof the one connector, a gear wheel partengaged with the gear part, and a gear memberhaving a spiral groove engaged with a driven projectionof the other connector, wherein the safety circuit unitis slidably disposed in the one connector, a small connectorfor connection is disposed in the other connector, thereby the driving lever, at a provisional position, prevents the safety circuit unit from rotating in a connecting direction of the safety circuit unit, and, at a connecting position, allows the safety circuit unit to move and is blocked to rotate by a flange

Low-insertion-force connector assembly

An object is to surely connect and disconnect the safety circuit for connectors with good workability. A low insertion force connector unit with a safety circuit unitis adopted. The low insertion force connector unit with a safety circuit unitincludes: a driving leverhaving an arc-shaped gear, an arc-shaped notchcontinued to the gear, an arc-shaped cam grooveformed in the same radius from a center axis 'm', and a straight groovecontinued to the cam groove; a gear unithaving a circular gearmeshed with the arc-shaped gear and a spiral groove, and attached to the one connector; a first driven projectionprovided on the other connector, and engaged with the spiral groove; one small connectorof the safety circuit unitprovided on the one connector movably in a connector fitting direction; a second driven projectionprovided on the one small connector; and the other small connectorof the safety circuit unitfixed to the other connector.
