摘要： The present invention suppresses the return of the barrel section while ensuring waterproofness against the contact portion with the aluminum core wire. A plurality of concave sections (114) is dispersedly provided on the inner surface (11a) of the barrel section (11). A groove section (116) is provided so as to overlap the sealing member (14). A ridge portion (117a) is provided extending in the crossing direction (D12) at a position which does not overlap with the sealing member (14) in plan view and is close to the third region (11a-3) on the side opposite to the terminal section. The barrel section (11) is crimped to the end portion (W1a) by crimping so that the exposed portion of the aluminum core wire (W11) is in contact with the ridge portion (117a), and is sealed with the sealing member (14).

摘要： A terminal metal fitting (20) includes a barrel portion (41) and a contact portion (31). The barrel portion (41) has a plate body to be formed into a tubular shape by overlapping its one end and its other end each other. The plate body has: a base portion (46); a tip portion (45); and an intermediate portion (47) connecting the base portion (46) and the tip portion (45) and to cover a conductor core wire (11) located between the base portion (46) and the tip portion (45). The barrel portion (41) has, at the one end portion of at least the intermediate portion (47) among the plate body, a bent portion (47a) having a bent shape toward the conductor core wire (11) before crimping and to be in pressure contact with the conductor core wire (11) after the crimping.

摘要： Electrical conductivity between an exposed aluminum core wire and a crimp terminal is sufficiently obtained while providing waterproof property with respect to a contact portion with the aluminum core wire. A method includes a placing step in which an end portion (W1a) of a covered electric wire (W1) is placed on an inner surface (11a) of a barrel portion (11) along an axial direction (D11) such that a tip (W11a) of the aluminum core wire (W11) overlaps a second portion (142) of a seal member (14) attached close to a terminal portion, and a crimping step in which the barrel portion (11) is wound around and crimped to the end portion (W1a), thereby fixing the crimp terminal (1) to the end portion (W1a) and sealing, with the seal member (14), a space between the inner barrel piece (112) and the outer barrel piece (113), an opening of the barrel portion (11) formed cylindrical located on a side of the terminal portion (12), and a space between the covered portion (W12) and the barrel portion (11).

摘要： Difficulty of manufacturing is reduced while providing waterproof property with respect to a contact portion with an aluminum core wire. A barrel portion (11) of a crimp terminal (1) includes an inner barrel piece (112) and an outer barrel piece (113), and an inner surface (11a) is provided with a plurality of recesses (114) arranged dispersedly, and a groove (116) extending in in a first region (11a-1) at the outer barrel piece (113), a second region (11a-2) at a location close to a terminal portion (12) and a third region (11a-3) on an opposite side. A second portion (142) of a seal member (14) formed from adhesive gel is formed into a strip-like shape having width that allows a part thereof to be pushed out after crimping, and a first seal portion (141) is formed into a shape corresponding to the groove (116) and having narrower width than the second seal portion (142).

摘要： Difficulty of manufacturing is reduced while ensuring waterproof property with respect to a contact portion with an aluminum core wire. A barrel portion (11) of a crimp terminal (1) includes an inner barrel piece (112) and an outer barrel piece (113), and includes a seal member (14) which is attached over a first region (11a-1), a second region (11a-2) and a third region (11a-3) and which seals, after crimping, a space between the inner barrel piece (112) and the outer barrel piece (113), an opening (11b) of the barrel portion on a terminal portion (12) side, and a space between a covered portion and the barrel portion (11). An inner surface (11a) of the barrel portion (11) is provided with a plurality of recesses (114) arranged dispersedly, the recess (114) having a circular shape in a plane view with respect to the inner surface (11a).
