A structure for connecting an aluminum cable and a terminal includes an aluminum cable and a terminal. The aluminum cable includes a cable core. The cable core is constructed with a cable welding portion. The terminal is welded to the cable welding portion. A nominal cross-sectional area of the cable core is M, and a welding area S between the cable welding portion and the terminal meets 5*M≤S≤6*M.

An endoscope device and a cable assembly thereof are provided. The cable assembly includes a first substrate, a second substrate, and a wire. The first substrate includes a first body and a first solder pad disposed on the first body. The second substrate is correspondingly disposed on the first substrate and includes a second body, a second solder pad disposed on the second body and corresponding to the first solder pad, and an accommodating portion corresponding to the second solder pad. The wire includes a soldering portion disposed in the accommodating portion. The first solder pad and the second solder pad are coupled to each other by at least one of a first solder and a second solder, and the soldering portion and the second solder pad are coupled to each other by the first solder.

A busbar is placed on an anvil, and a core wire of a cable is placed on the busbar. While the core wire is pressed onto the busbar using a horn chip, ultrasonic vibration is given to the core wire to join the core wire to the busbar. The horn chip has two flat portions and a recessed portion located between the flat portions. When the core wire is pressed onto the busbar using the horn chip, each of the flat portions and the busbar sandwich a part of the core wire therebetween while the recessed portion and the busbar put a remaining part of the core wire therebetween. Each of the sandwiched parts of the core wire does not reach an outer end of the corresponding flat portion to leave a space between the corresponding flat portion and the busbar.

One aspect is a system for reception or emission of an electrical signal from or into the human or animal body, comprising at least one insulated electrical conductor; a sleeve-shaped electrode that is electrically connected to the electrical conductor and includes an internal side, an external side, and a channel, wherein the channel defines a longitudinal axis along which the conductor is arranged. According to one embodiment, the conductor extends without interruption along the entire area of the electrode, and the electrode further includes a slit that extends from the internal side to the external side of the electrode and in which the conductor is appropriately arranged in the slit such that the electrode forms a direct durable mechanical and electrical connection to the conductor.

An objective of the present invention is to provide a terminal connecting structure which may enable the conductivity to be improved. A terminal connecting structure is intended for connecting a terminal to an electric wire, the electric wire including an aluminum conductor with aluminum, wherein the terminal connecting structure further comprises a conductive connection body formed with aluminum, wherein one end of the connection body is butt-connected to the aluminum conductor, and wherein another end of the connection body is connected to the terminal via crimping. This enables the terminal to be connected to the electric wire via the connection body without crimping the bundle of cores. This may eliminate influence of crimping on the aluminum conductor and enable the conductivity between the electric wire and the terminal to be improved.

A terminal-equipped electric wire manufacturing method includes: an electric wire installation step of inserting a core-wire exposed part between inner wall surfaces of piece parts of a core-wire connection body, the core-wire exposed part having a core-wire diameter smaller than an interval between the inner wall surfaces of the piece parts; a melting step of melting the core-wire exposed part and the core-wire connection body by emitting a laser beam to the core-wire exposed part and the core-wire connection body from a free end side of each piece part; and a fixation step of fixing the core-wire exposed part and the core-wire connection body thus melted, with the emission of the laser beam stopped.

A welded body manufacturing method for a welded body in which a terminal formed of a metal base material and plated with a metal material having a hardness lower than a hardness of the metal base material is connected to an end portion of a conductive member, the conductive member being connected to the terminal on a conductor welding surface of the terminal is provided. The manufacturing method includes forming at least one of a convex portion and a concave portion on the conductor welding surface and connecting the conductive member to the conductor welding surface by means of ultrasonic welding.

A conductive connecting member includes a first terminal, a second terminal, and a braided member for electrically connecting the first and second terminals. The braided member is a member formed by braiding a plurality of metal stands each other. The braided member includes a first fixing portion to be fixed and electrically connected to the first terminal, a second fixing portion to be fixed and electrically connected to the second terminal and an intermediate portion serving as a part of the braided member between the first and second fixing portions. The intermediate portion retains its own shape in a natural state where no external force is applied and is deformed to allow a relative movement of the second terminal with respect to the first terminal when an external force for relatively changing a position of the second terminal with respect to the first terminal is applied.

A connector includes a terminal, an electric wire, and a housing having a tubular portion that accommodates the terminal and the electric wire therein. An electric wire connection portion and a terminal connection portion are provided on both end sides of the terminal. The electric wire connection portion is connected to the electric wire. A joining portion between an end surface of the electric wire connection portion and an end surface of the electric wire includes a protruding piece protruding in a radial direction of the electric wire connection portion. A first retaining piece and a second retaining piece configured to be locked to the protruding piece are provided on an inner peripheral surface of the tubular portion. The second retaining piece is disposed at a position shifted from the first retaining piece in both a circumferential direction and an axial direction of the tubular portion.

An audio plug which comprises a head and a body, a through opening through the body having a rotational symmetry and being configured to allow the passage of at least two cables through the body, a shoulder being formed on the inner surface of the body to form a first cylindrical section on the upstream side and a second cylindrical section on the downstream side on the body, the audio plug further comprising a ring presenting a shoulder on its outer surface to form a first section with a diameter corresponding to the diameter of the first section of the body and a second section with a diameter corresponding to the diameter of the second section of the body, the ring presenting a through opening according to the longitudinal direction, at least one locking member being formed on the inner surface of the ring and being configured to lock the at least two cables relative to the ring, the ring being configured to be inserted into the body to cover the ends of the cables connected to the connection terminals before fixing the body to the head.
