A terminal-equipped electric wire includes a terminal to be electrically connected to a connection target member, and an electric wire to be connected to the terminal by ultrasonic joining. The terminal includes a joint portion to be connected to the electric wire, a connection portion to be connected to the connection target member, and a plating layer on a surface of the terminal. The connection portion has an uneven shape on at least a part of a surface thereof. When the terminal-equipped electric wire is connected to the connection target member, an insulating coating of the plating layer covering at least a part of the surface of the connection portion is broken.

An electrical device having a stranded wire contact. The device includes a stranded wire with individual wires and a contact piece for electrical contacting of the stranded wire. The stranded wire contact is produced by thermal diffusion bonding.

An electric cable includes a terminal, and a manufacture method thereof is to suppress shedding of wire strands from a core wire. The electric cable with terminal includes an end of an electric cable connected to the terminal. The electric cable includes a core wire that is a bundle of a plurality of wire strands. The terminal includes a connection portion in which the core wire is exposed at the end of the electric cable. The core wire is placed on the connection portion including a welded portion that is to be ultrasonic welded to the connection portion. The welded portion includes a high compression portion in which the core wire is compressed, and a low compression portion in which a position that is closer than the high compression portion to the end of the core wire is compressed at a compression lower than that of the high compression portion.

Systems and methods are provided for wire processing. In certain examples, a wire processing system is disclosed. The wire processing system includes an electrical wire and solder sleeve joining system. The electrical wire and solder sleeve joining system includes an end effector configured to hold a solder sleeve and a split funnel configured to guide insertion of wire into the solder sleeve, allow movement of the solder sleeve through the split funnel in a second position, and prevent movement of the solder sleeve through the split funnel in a first position. The end effector can additionally be configured to remove a slug from the wire.

A contact assembly for an electrical connector includes a contact positioner having contact support walls holding a contact array. The contact array includes signal contacts and ground contacts interspersed with the signal contacts. The signal contacts include mating ends configured to be mated with a mating electrical connector and mounting ends configured to be terminated to a host circuit board. The signal contacts include transition portions between the mating ends and the mounting ends. The ground contacts include mating ends, mounting ends, and transition portions between the mating ends and the mounting ends. The contract assembly includes a ground bus wire extending transversely across the contact array. The ground bus wire is electrically connected to each of the ground contacts. The ground bus wire is electrically isolated from each of the signal contacts.

A conductive terminal for a flat flexible cable comprises a first contact surface, and a second contact surface opposing the first contact surface. The first and second contact surfaces define a space therebetween for receiving a flat flexible cable along a longitudinal direction of the terminal. A dimpled structure is defined on the first contact surface and includes a plurality of dimples extending from the first contact surface in a direction of the second contact surface. The dimpled structure includes at least one dimple having a first height, and at least one dimple having a second height, distinct from the first height.

A method for producing an electrical feedthrough with an inner conductor arranged in some sections in a metallic outer pipe and electrically insulated from this outer pipe by an electrically insulating material. The inner conductor of the feedthrough has a contact section projecting out of the metallic outer pipe. The metallic outer pipe, the electrically insulating material, and the sections of the inner conductor, which are already arranged in the metallic outer pipe, are compressed with each other to form a module, in which the contact section projecting out of the metallic outer pipe is joined to the inner conductor only after completion of the compression of the metallic outer pipe, the electrically insulating material, and the sections of the inner conductor, which are already arranged in the metallic outer pipe. The contact section is positioned such that it is oriented along the center axis of the metallic outer pipe.

A stator of an electric rotary machine includes a first abutting portion and a second abutting portion. The first abutting portion and the second abutting portion are welded by laser welding in a state where the abutting portions abut against each other, and the first abutting portion and the second abutting portion include bonding surfaces which are bonded to each other. In the axial direction, a height from an insulating cover film to the bonding surface in one abutting portion is greater than a height from an insulating cover film to the bonding surface in the other abutting portion, and in a radial direction, a protruding distance from the insulating cover film to the bonding surface in the one abutting portion is greater than a retraction distance from the insulating cover film to the bonding surface in the other abutting portion.
