CONNECTION TERMINAL, TERMINAL-ATTACHED WIRE, AND WIRING HARNESS

WIPO Patent Application WO/2021/065358

A1

Provided are a connection terminal, a terminal-attached wire, and a wiring harness that can maintain the corrosion-resistant properties thereof even when placed in a high temperature environment.　A connection terminal 1 includes: a terminal metal part 10 including a terminal connecting part 11 that is electrically connected to a mating terminal, and a barrel part 12 that secures electrical wiring in place by swaging; and a water-stopping member 20 that is provided on the inner surface 12c of the barrel part 12 in electrical contact with the electrical wiring and that comprises an adhesive material. The water-stopping member 20 has a contact surface that is in contact with the inner surface 12c of the barrel part 12 and also has an exposed surface 20b facing away from the contact surface. Both the contact surface and the exposed surface 20b have an adhesion strength A1 of at least 0.5 MPa with respect to a constituting material of the terminal metal part 10. Furthermore, when the adhesion strength with respect to the constituting member of the terminal metal part 10 upon subjection to 100-hour heating at 120°C is A2, the adhesion strength increase rate A, which is calculated as A = (A2-A1)/A1×100%, is no more than 100%.
