A connector includes: a terminal fitting connected to an electric wire; a housing including a housing chamber, an electric wire drawing port, a communication hole, and a counterpart fitting chamber where a gap formed between the counterpart fitting chamber and a counterpart terminal fitting is filled with a first sealing member; a lid member; a second sealing member that fills a gap between these and forms a first sealed space part in the housing with the first sealing member; a waterproof member including one end part in close contact with an end part of the housing, the other end part in close contact with the electric wire drawn from the electric wire drawing port, and a tubular part, the tubular part including a second sealed space part communicating with the first sealed space part through the electric wire drawing port; and a ventilation component.

Connector and connector-equipped electric wire

A waterproof construction of a three-phase line part includes a three-phase line part having three bus bar construction bodies, a first terminal block provided on one end side of the three-phase line part, a second terminal block provided on the other end side of the three-phase line part, and a tubular exterior member that covers a middle portion of the three-phase line part. One end of the tubular exterior member is water-tightly fixed to a first housing of the first terminal block, and the other end thereof is water-tightly fixed to a second housing of the second terminal block, in a state that the tubular exterior member covers the three-phase line part.

Waterproof construction of three-phase line part and three-phase line connecting device

A connector includes: a terminal fitting connected to an end of an electric wire; a housing including a housing chamber and an electric wire drawing port; a first waterproof member that is elastically deformable and fills a space between an inner peripheral surface of the housing and an outer peripheral surface of a cover of the electric wire in the housing chamber to form a first sealed space part between the first waterproof member and the electric wire drawing port; a second waterproof member that is elastically deformable and includes one end part, an other end part, and a tubular part, the tubular part having a second sealed space part that communicates with the first sealed space part through the electric wire drawing port; and a ventilation component.

There is provided a method for manufacturing an electrical wire. The electrical wire includes a rod-like conductor having a shape corresponding to a predetermined wiring route and also having rigidity to enable the rod-like conductor to maintain the shape, and an insulation sheath covering the rod-like conductor. The method includes: preparing a plurality of rod-like preliminary conductors having the rigidity so as to correspond to a plurality of sub routes into which the wiring route is divided; processing at least one of the plurality of preliminary conductors into a shape conforming to the corresponding sub routes; connecting the plurality of preliminary conductors together to form the rod-like conductor; and forming the insulation sheath to cover the rod-like conductor.

Method for manufacturing an electrical wire

An exterior member of an electrical wire includes a first tubular body and a second tubular body. The first tubular body includes a hollow portion through which the electrical wire is inserted, an opening portion from which the electrical wire is drawn out, and a vent portion which is impermeable to moisture and permeable to air. The second tubular body is provided to extend from the first tubular body and to cover an outer periphery of the electrical wire drawn from the opening portion, and is made of a material more flexible than a material of the first tubular body.

Exterior member of electrical wire

There is provided a wire harness and a manufacturing method thereof. A wire harness routed in a vehicle body is provided with an electric wire and a metallic shield pipe in which the electric wire is inserted. The shield pipe has a rigidity that enables self-maintenance of an after-bent shape. The shield pipe is bent with the electric wire being inserted therein so as to form the shield pipe in a shape conforming to piping to be assembled to the vehicle body.

Wire harness and manufacturing method thereof

A wire harness includes a plurality of electric wires, a plurality of tubular metal pipes corresponding the number to the plurality of electric wires, each of the plurality of electric wires being inserted through respective one of the plurality of tubular metal pipes, a connector configured to be connected to end portions of the plurality of electric wires, and a tubular metal connecting portion provided at a pipe end portion of each of the plurality of pipes and connected to the connector. Each of the pipes has a rigidity capable of self-holding a bent shape thereof when each of the pipes are bent. The connecting portion has a flexibility incapable of self-holding a bent shape thereof when the connecting portion is bent.
