摘要： A noise reduction unit includes a conductor having a winding portion and a ring-shaped core which is made of a magnetic material and is inserted through the winding portion, and a housing which houses the conductor and the ring-shaped core. An inner wall surface of the housing is formed with a recess configured to receive a part of the winding portion located on an outer circumferential surface of the ring-shaped core. The conductor is housed in the housing so that the part of the winding portion is received in the recess.

摘要： A surge voltage reduction member includes a tubular magnetic body having a through-hole and at least one coil wire. The coil wire is inserted through the through-hole and has a winding portion which is winded around a portion of the magnetic body. The coil wire is formed by connecting a bent coil element wire and a straight coil element wire. Where the coil wire has two or more bent coil element wires, the winding portion is formed by connecting the through-hole passing portion of one of adjacent bent coil element wires to the outside passing portion of the other of the adjacent bent coil element wires and connecting the outside passing portion of the one of the adjacent bent coil element wires to the straight coil element wire.

摘要： A noise filter (10) is equipped with plural conductors (20) having respective winding portions (21) and a ring-shaped core which is inserted through the winding portions of the plural conductors and made of a magnetic material. The ring-shaped core has a core main body (40) having a pair of extension portions (41) and (42) that are connected to each other at one end and a link core (50) which is attached to the core main body at the other end and thereby connects the extension portions and. At least one of the extension portions and of the core main body is straight. The plural conductors are arranged in a row in a state that the straight extension portion is inserted through the winding portions of the plural conductors.

摘要： A waterproof structure includes a seal portion covering around an electric wire to be inserted into a mounting hole of an object to which the electric wire is mounted, the electric wire having a conductor and an insulation covering the conductor, and the seal portion being elastic and electrically insulative and a housing covering an end portion of the electric wire such that the housing overlaps the seal portion, the housing being made of an insulating resin having higher rigidity than the seal portion. The seal portion includes a first portion including one end of the seal portion and over which the housing overlaps the seal portion and a second portion other than the first portion and over which the housing does not overlap the seal portion, the first portion being smaller in outer diameter than the second portion.

摘要： A routing structure of electrical wires and a wire harness include multi-phase electrical wires and a magnetic core having a ring shape, around which the electrical wires are winded. The magnetic core has a division type in which the first component constituting a part of the ring shape, and the second component constituting a remaining part of the ring shape are connected. The electrical wires with all the phases may be winded around the first component.

摘要： A connector includes a conductor, a noise filter part, an inner mold part, and a housing. The conductor has a terminal at one end and the other end of the conductor is connected to a wire. The connector is to be joined with a counterpart connector so that the terminal is in conduction with a terminal of the counterpart connector. The noise filter part includes a core attached to the conductor and formed of a magnetic member which reduces noise of a current flowing in the conductor. The inner mold part is integrally molded with the noise filter part so as to cover at least a periphery of the core and formed of a soft resin material. The housing which covers a periphery of the inner mold part and is formed of a hard resin material.
