Abstract
The present invention provides a terminal-equipped electric wire and a wire harness in which the electrical connection portion between a terminal fitting and the electric wire is covered with a resin coating portion and a terminal-equipped electric wire and a wire harness, wherein, even without using a special structure, the terminal The peeling due to temperature cycle can also be suppressed at the interface between the component and the wire covering layer and the resin covering part. An electric wire (1) with a terminal, which is a terminal fitting (5) and an electric wire (2) covered with an insulating coating layer (4) on the outer periphery of a conductor (3) is electrically connected at an electrical connection part (6). Connecting, a terminal-equipped electric wire having a resin covering part (7) made of a resin material and covering an electrical connection part (6), wherein the resin covering part (7) is connected to a terminal fitting (5) and an insulating covering layer ( 4) Contact, the tensile shear bonding strength between the resin coating part (7) and the terminal fitting (5) is 1.0MPa or more, and the bonding strength between the resin coating part (7) and the insulating coating layer (4) The tensile shear adhesive strength is 0.5 MPa or more.
Description
technical field [0001] The present invention relates to an electric wire with a terminal and a wire harness. More specifically, it relates to an electric wire with a terminal having a corrosion-resistant resin coating portion on an electrical connection portion between a conductor and a terminal fitting, and a wire harness using the same. Background technique [0002] Terminal fittings are connected to conductors at the ends of electric wires laid in vehicles such as automobiles. Corrosion prevention is required at an electrical connection portion that electrically connects a terminal fitting and a conductor of an electric wire. Especially in the electrical connection part, when different metal materials come into contact, corrosion between dissimilar metals may occur. In an electric wire used in a vehicle, aluminum or an aluminum alloy may be used as a material of a conductor for the purpose of reducing the weight of the vehicle or the like. On the other hand, copper or a...
