Wires and harnesses with terminals

Abstract

To provide an electric wire with a terminal and a wire harness which can easily ensure high anticorrosion performance even if the thickness of the resin material constituting the resin covering part which covers the electrical connection part between the terminal part and the electric wire conductor is reduced. cover. It is assumed that the terminal part (1) is as follows: the terminal part (5) and the electric wire (2) covered with the outer periphery of the conductor with the insulating coating layer (4) are electrically connected at the electrical connection part, and the terminal part (5) is made of a resin material and has an electrical connection. The resin covering part (7) covered by the connection part, wherein the resin covering part (7) has a first covering layer (8) and a second covering layer (9), and the first covering layer (8) and The surface of the terminal part (5) is arranged in contact with the area covering at least a part of the terminal part (5), the second covering layer (9) covers at least part of the first covering layer (8), and the first The cladding layer (8) has a recess covered by the second cladding layer (9).

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 an anticorrosion resin coating portion on an electrical connection portion between a conductor and a terminal component, and a wire harness using the electric wire with a terminal. Background technique [0002] Terminal parts 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 where terminal parts and conductors of electric wires are electrically connected. In particular, when different metal materials are in contact with each other at the electrical connection part, there is a possibility that dissimilar metal-to-metal corrosion may occur. In electric wires used in vehicles, for the purpose of reducing the weight of vehicles, etc., aluminum or aluminum alloys are sometimes used as co...
