TERMINAL, WIRE HARNESS, TERMINAL AND COATED CONDUCTOR WIRE CONNECTION METHOD, AND WIRE HARNESS STRUCTURE
First Claim
1. A terminal connected to a covered conductor wire, the terminal comprising:
- a terminal main body; and
a cylindrical crimping portion;
the crimping portion including;
a cover crimping portion that crimps a covering portion, anda conductor wire crimping portion that crimps a conductor wire exposed from the covering portion, the crimping portion being sealed in all areas excluding an area through which the covered conductor wire is inserted; and
the conductor wire crimping portion including a plurality of depressions on an inner surface thereof, the depressions being formed in a plurality of rows in an axial direction of the conductor wire crimping portion and including main depressions formed at a substantial center in the axial direction of the conductor wire crimping portion and sub-depressions formed on both sides of the main depressions, the main depressions being formed substantially across an entire periphery of the wire crimping portion, and the sub-depressions having a formation range shorter than that of the main depressions and not being formed on an upper side of the wire crimping portion.

Abstract
A conductor wire crimping portion (7) has depressions (13a, 13b, 13c) that are disposed at prescribed intervals in the axial direction and that are linear locking portions. The depressions (13a, 13b, 13c) are continuously depressed grooves on the inner surface of a crimping portion (5). On an upper die (30a), at a portion corresponding to the conductor wire crimping portion (7), a straight portion is formed, and in the front-back direction thereof, tapered portions are formed. More specifically, the upper die (30a) is formed to have an inverted trapezoid shape, a middle portion of which protrudes in the crimping direction. Consequently, at each boundary between the straight portion and the tapered portion, a die angled portion (32) is formed. At an area corresponding to the straight portion of the upper die (30a), the depression (13a) is provided, and at an area corresponding to the die angled section (32), the depression (13b) is provided.
