A terminal metal fitting 1 includes a terminal connection portion 2 connected to a partner terminal metal fitting, and a wire holding portion 3 provided at the back of the terminal connection portion 2. The wire holding portion 3 is configured to hold, in a pressure-bonded state, an insulating wire 100 configured such that a core wire is coated by an insulating coating. The wire holding portion 3 includes a bottom wall portion 31 on which the insulating wire 100 is placed, a first insulating wire swaging portion 32 formed continuously to one side edge of the bottom wall portion 31, and a second insulating wire swaging portion 33 formed continuously to the other side edge of the bottom wall portion 31. One or more claws 34 configured to bite into the insulating wire upon swaging of the insulating wire 100 are formed at at least one of the bottom wall portion 31, the first insulating wire swaging portion 32, or the second insulating wire swaging portion 33.

An electrical connector includes at least two electrical connector elements extending side by side along a longitudinal direction, each of the electrical connector elements being connectable to a respective wire of an associated electrical cable. An electrical device is in electrical contact with the respective electrical connector elements. A flexible carrier bears inwardly against the electrical connector elements. The electrical device is mounted on an inner side of the flexible carrier which faces the connector elements.

To provide a method and a device for manufacturing a connection structure (1) and a wire harness (2). The connection structure connects an insulated wire (100) comprising a wire tip portion (103), an insulating covering (102) being stripped from the tip thereof, to a crimp terminal (200) comprising a closed-barrel-type crimping portion (230) allowing crimp connection with the wire tip portion (103) and has stable conductivity by crimping an aluminum core wire (101) by the crimping portion (230). The method comprises a carrier cutting step for separating crimp terminals (200) from a terminal connecting belt (300) comprising the crimp terminals (200) attached to a carrier (250) in a longitudinal direction, a wire insertion step for inserting wire tip portions (103) into the crimping portions (230) of the separated crimp terminals (200), and a crimping step for crimping the crimping portions (230) with the inserted wire tip portions (103).

A terminal-attached electric wire (1) includes: an electric wire (10) and a terminal metal fitting (20). The terminal metal fitting (20) has: a barrel portion (41); and a contact portion (31). The barrel portion (41) has: a base portion (46, 47) swaged to a cover body (12) of the electric wire (10); and a tip portion (45) being spaced from the base portion (46, 47) and swaged to be electrically connected to a conductor core wire (11). The cover body (12) is extended inside a base-side opening portion (45a) of the tip portion (45). The cover body (12) and the conductor core wire (11) are fastened together at the base-side opening portion (45a). The cover body (12) isolates the conductor core wire (11) located between the base portion (46, 47) and the tip portion (45) from outside.
