Terminal-provided wire

摘要

A terminal-provided wire (1) includes an insulated wire (10) with an insulation coating (12) made of polyolefin-based resin, an adhesive layer (30) formed on a surface of the insulation coating (12) over the entire circumference and a waterproof resin portion (40) formed by insert molding. The waterproof resin portion (40) covers an area from a part of the insulated wire (10) where the adhesive layer (30) is formed to a connected part (21) of a metal terminal (20) to a core (11). The adhesive layer 30) is made of modified olefin-based resin, which is olefin-based resin modified with a polar group. The waterproof resin portion (40) is made of aromatic nylon.

主权项

1. A terminal-provided wire, comprising:
an insulated wire including an end, an electrically conductive core extending to the end and an insulation coating made of a polyolefin-based resin covering the core to a location spaced from the end; a metal terminal electrically connected to the core at the end of the insulated wire at a connection area; an adhesive layer made of a modified olefin-based resin, which is an olefin-based resin modified with a polar group, the adhesive layer being bonded on a molecular level to the polyolefin-based resin insulation coating at an end part of the insulated wire over an entire outer circumference of the insulation coating; and a waterproof resin portion made of aromatic nylon and covering a protection area that includes at least an area from a part of the insulated wire; the adhesive layer closing a clearance between an outer surface of the insulation coating and an inner surface of the waterproof resin portion, and wherein the adhesive layer is made of a material that is stretchable by 104.7% or more at −40° C. in a test in accordance with the provision of JIS K6251.
