Abstract

A terminal-equipped wire for charging inlet is provided with a wire including a conductor and an insulation coating, and a terminal to be connected to the conductor exposed from an end part of the wire. The insulation coating has an olefin-based resin as a main component. The terminal-equipped wire is further provided with 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 are directly in contact.

First claim

What is claimed is:

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 having an annular shape and being disposed around an outer periphery of a part of the terminal located further than the tip of the conductor in the first direction,

wherein the annular shape of the primer layer has a width determined by a first primer layer edge extending in the first direction and a second primer layer edge extending in a second direction opposite to the first direction, the second primer layer edge being located further than the tip of the conductor in the first direction, and
wherein the primer layer is fully disposed between an end part of the heat shrinkable tube toward the terminal and the tip of the conductor, such that the first primer layer edge is disposed a distance from the end part of the heat shrinkable tube and such that the region of the terminal covered by the heat shrinkable tube includes a region of the terminal arranged further than the first primer layer edge 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.
