Abstract

This terminal-equipped electric wire for a charging inlet comprises: an electric wire that has a conductor and an insulation coating; and a terminal that is connected to the conductor exposed on the end part of the electric wire. The insulation coating has an olefin resin as the main component thereof. The terminal-equipped electric wire further comprises: heat-shrinkable tubing that covers a region spanning from a site where the conductor and the terminal are connected to the insulation coating; and a primer layer that is provided between the inner peripheral surface of the heat-shrinkable tubing and the outer peripheral surface of the terminal. The inner peripheral surface of the heat-shrinkable tubing and the outer peripheral surface of the insulation coating are in direct contact.

First claim

1 . A terminal-equipped wire for charging inlet, comprising:
a wire including a conductor and an insulation coating, an outer diameter of the conductor being 13 mm or more, the insulation coating having an olefin-based resin as a main component; a terminal to be connected to the conductor exposed from an end part of the wire; a heat shrinkable tube for covering a region from a connection point of the conductor and the terminal to the insulation coating; and a primer layer provided between an inner peripheral surface of the heat shrinkable tube and an outer peripheral surface of the terminal, the inner peripheral surface of the heat shrinkable tube and an outer peripheral surface of the insulation coating being directly in contact, a direction toward a tip of the terminal being a first direction, the heat shrinkable tube extending further than a tip of the conductor in the first direction, and the primer layer being annular around an outer periphery of a part of the terminal located further than the tip of the conductor in the first direction.

2 . The terminal-equipped wire of claim 1 , wherein the olefin-based resin is polyethylene or polypropylene.

3 . The terminal-equipped wire of claim 1 , wherein the primer layer has a styrene-ethylene-butylene-styrene block copolymer as a main component.

4 . The terminal-equipped wire of claim 1 , wherein the heat shrinkable tube has an olefin-based resin as a main component.
