A production method for a terminal includes: a first pressing step for pressing a parent material plate made of a conductive metal and punching out a prescribed shape; a second pressing step following the first pressing step, for bending the plate of prescribed shape, and forming a terminal provided with a box part onto the front surface of which opens a terminal insertion port into which a partner terminal is inserted, and a spring contact part arranged inside the box part; and a plating step following the second pressing step, for plating at least the spring contact part with a conductive metal.

Production method for terminal, and terminal

A method for manufacturing a terminal with an electric wire includes: forming a conductor exposed portion by removing a resin coating of an electric wire; forming a wire-terminal connection portion by connecting a terminal fitting to a position of the conductor exposed portion; and supplying a sealing material from a nozzle to the wire-terminal connection portion. During supply of the sealing material, the nozzle is moved in X-, Y- and Z-directions or a relative position between the wire-terminal connection portion and the nozzle is changed in the X-, Y- and Z-directions.

Method for manufacturing terminal with electric wire

A method for manufacturing a terminal with an electric wire includes: forming a conductor exposed portion by removing a resin coating of an electric wire; forming a wire-terminal connection portion by connecting a terminal fitting to a position of the conductor exposed portion; supplying a sealing material made of ultraviolet-curing resin from a nozzle to form a sealing portion covering the wire-terminal connection portion; and curing the sealing material by irradiation with ultraviolet rays from a UV light. During curing of the sealing material, a reflector is used to allow the ultraviolet rays to be reflected toward the sealing material supplied to the wire-terminal connection portion.

Provided is a coating device and a method capable of coating a conductor of a plurality of electrical wires with coating material with simple configuration and of coating without exposing the conductor. A nozzle and a coating area of a terminal-equipped electrical wire are applied to voltage by a voltage applying unit such as to be electrified with polarity different from each other, and jetting jet liquid forms jet liquid over the whole coating area, forms the coating layer with anticorrosion material on a surface of the terminal-equipped electrical wire, and coats the coating area including a conductor with anticorrosion material without being exposed. Furthermore, it is possible to allow the nozzle jet the jet liquid and to move the nozzle in an arranging direction of the terminal-equipped electrical wire, and also to coat the coating area of the terminal-equipped electrical wire with anticorrosion material.

Coating device and method of coating

A terminal with a wire having a high sealing property, a manufacturing method thereof, and a wire harness are provided. The terminal with the wire includes an aluminum wire and a crimp terminal. A resin covering member is removed from the aluminum wire to form a conductor exposed portion (a wire forming process). The crimp terminal is connected to the conductor exposed portion to form a wire-terminal connection portion (a wire-terminal connection process). Then, an anticorrosion portion is formed such that a voltage is applied between the crimp terminal and a metal nozzle and an electrified anticorrosion material is supplied from the metal nozzle to the wire-terminal connection portion in a state of being attracted (an anticorrosion material supply process). Further, the anticorrosion portion is formed by irradiating the anticorrosion material with an ultraviolet ray to be UV-cured (an anticorrosion material curing process).

Terminal with wire, manufacturing method of terminal with wire, and wire harness

In a manufacturing method of an aluminum wire crimp terminal formed by a base material made of a copper-based metal, at the step of forming an intermediate worked material having an unfolded shape of the crimp terminal, fine recessed parts for promoting the adhesive performance of the crimp terminal against a conductor of the wire are formed on a plate-body surface forming an inner face of a conductor crimping part of the intermediate worked material. Subsequently, a thin-film surface layer made of an aluminum-based metal is formed on at least the plate-body surface. Finally, the intermediate worked material is bent to a prescribed terminal shape.

Provided is a waterproof connector capable of reducing water-stopping warranty portions. A waterproof connector is configured to include an outer housing, an inner housing, a terminal-equipped with electrical wire, and a packing mat seal. In a bottom wall of the outer housing, a locking projection on the left side and a locking projection on the right side served as engagement part with respect to the inner housing are integrally formed. Further, in the bottom wall in the outer housing, the packing mat seal is integrally molded so as to adhere to circumferential surfaces of proximal end sides in the locking projection on the right side and the locking projection on the left side. An integral molding of the packing mat seal provides a watertight property between a packing mat seal and the circumferential surfaces of the proximal end sides in the locking projection and the locking projection.

Waterproof connector

A connector having a housing is disclosed. The housing of the connector includes a receiving chamber group having four terminal receiving chambers in which a terminal is inserted, and a lance body surrounded by the four terminal receiving chambers. Each of the four terminal receiving chambers is arranged so that each axis thereof is positioned in four vertexes of a square. The lance body integrally has four flexible lances arranged corresponding to each four terminal receiving chambers. Each of the four flexible lances has a locking portion. Further, each the four flexible lances is arranged in a diagonal line so that the free end is bent in a diagonal direction of the square when inserting/extracting the terminal into the terminal receiving chamber and the locking portion is locked or unlocked on the step of the terminal.
