[0043] Wires attached to terminals:

[0044]As shown in FIGS. 1-4 , the terminal-attached electric wire 1 according to this embodiment includes an electric wire 10 having a conductor 11 and a wire cover member 12, and crimping of the conductor 11 connected to the electric wire 10. Terminal 20. The terminal-attached electric wire 1 also includes a corrosion-resistant member 30 which is connected to the peripheral portion of the joining section inserted between the conductor 11 and the crimp terminal 20, and the wire covering member 12 adjacent to the joining section. The peripheral part is integrally formed. In addition, a primer 31 is placed at a gap between the corrosion-resistant member 30 and the bonding section inserted between the conductor 11 and the crimp terminal 20 .

[0045] The crimp terminal 20 on the terminal-attached electric wire 1 is of a female type and has an electrical connection section 21 at its front to be connected to a corresponding terminal (not show...

[0075] Regarding Examples 1-1 to 1-3 and 2-1 to 2-3, first, the materials of the corrosion-resistant member 30 and the primer 31 shown in Table 1 and Table 2 were prepared. An electric wire having a conductor made of aluminum and a wire covering member made of polypropylene (pp) was prepared. A crimp terminal using tin-plated copper as the terminal element is prepared.

[0076] Next, the electric wire 10 and the crimp terminal 20 are connected to each other, and then the joining section inserted between the crimp terminal 20 and the electric wire 10 is placed on a metal mold. The primer 31 is applied to the entire peripheral portion of the base plate section 28 and the conductor crimp section 24 of the crimp terminal 20 and cured. Thereafter, the inner section of the metal mold was filled with the material of the corrosion-resistant member 30 of each example, the material was melted by heating, and the metal mold was cooled so that the melted material of the corrosion-resista...

Abstract

A terminal-attached electric wire of the invention includes an electric wire having a conductor and an electric wire cover member covering the conductor, and a crimping terminal connected to the conductor of the electric wire. The terminal-attached electric wire further includes a corrosion resistant member integrally formed with a peripheral portion of a joint section interposed between the conductor and the crimping terminal and a peripheral portion of the electric wire cover member adjacent to the joint section. The corrosion resistant member contains a thermoplastic elastomer as a main component. A peel strength of bonded assemblies between the corrosion resistant member and a terminal member of the crimping terminal is equal to or greater than 0.2 N / mm, and a peel strength of bonded assemblies between the corrosion resistant member and the electric wire cover member is equal to or greater than 0.5 N / mm.

Description

technical field [0001] The present invention relates to terminal attached electric wires. Specifically, the present invention relates to a terminal-attached electric wire configured such that a corrosion-resistant member is placed at a peripheral portion of a joint section inserted between a conductor of the wire and a crimp terminal. Background technique [0002] In recent years, the number of cases where aluminum is used as a covered electric wire constituting a wire harness has been increasing from the viewpoint of improving fuel consumption by reducing the weight of a vehicle. Generally, copper or copper alloys superior in electrical properties are used as terminal metal clamps connected to covered electric wires such as those described above. However, when the materials of the conductor covering the electric wire and the terminal metal jig are different from each other, corrosion occurs on a contact section inserted between the conductor and the terminal metal jig. Th...
