Embodiment approach

[0031] (structure)

[0032] figure 1 It is a diagram schematically showing a cross-sectional structure of an end of an automotive wire harness according to a preferred embodiment of the present invention.

[0033] Such as figure 1 As shown in , a covered electric wire 10 including a plurality of bare conductors 11 and a covering portion 13 (not shown) for insulating covering the bare conductors 11 includes an exposed portion 22 at an end thereof, in which exposed parts made of The plurality of bare conductors 11 constitute a part of the conductor group 12 . The bare conductor 11 is preferably made of aluminum.

[0034] The terminal member 1 is fixed to an end portion of the covered electric wire 10 . Specifically, the terminal member 1 is fixed to the end portion of the covered electric wire 10 so that the crimping portion 1A included at one end of the terminal member 1 is crimped along the outer surface of the covering portion of the covered electric wire 10, and the term...

Abstract

The disclosed terminal structure for a wire harness for use in a vehicle exhibits a high degree of corrosion prevention. In a terminal region of a jacketed electric wire (10), a caulk section (1A) formed at one end of a connector (1) is caulked along the outside of a jacket part of said jacketed electric wire (10), affixing the connector (1) to the terminal part of the jacketed electric wire (10). At a minimum, the entire circumference of an end exposed region (a region including a break plane (1r) and a base edge (1e)) of the caulk section (1A) and the vicinity thereof is completely covered, forming a resin part (20). The resin part (20) is formed by curing a material that consists primarily of an epoxy resin that exhibits a viscosity in the range 1,000 to 30,000 mPas at 25 DEG C, as measured pursuant to JIS Z8803.

Description

technical field [0001] The present invention relates to an end structure of a wire harness for automobiles. Background technique [0002] Conventionally, for example, the structure of covering the end connection portion of electric wires disclosed in Patent Document 1 is used for a structure in which waterproof treatment is performed by resin molding in the end portion of a wire harness to which a corresponding terminal member is fixed. [0003] The resin-molded terminal connection portion of covered electric wires shown in Patent Document 1 is produced by injecting molten molding resin into a molding cavity space provided in a mold composed of an upper mold and a lower mold. The molding cavity space is a cavity for molding in which a terminal connection portion prepared by crimping a terminal member on an end conductor of a covered electric wire is housed and set for injection. [0004] Thus, the terminal connection portion of the covered electric wire shown in Patent Docu...
