Electrical connector apparatus with improved waterproofing and compact size and method of manufacturing thereof

A wire with terminal WTis provided with a wireincluding a coreB and an insulation coatingC covering around the coreB, and a terminalincluding a coating crimping portioncrimped to the insulation coatingC. The wireis pulled out rearward from the terminal. A water cut-off memberfor suppressing liquid intrusion into the coreB is disposed between an inner peripheral surfaceA of the coating crimping portionand an outer peripheral surfaceA of the insulation coatingC. The coating crimping portionis provided with an oblique extending portionfor reducing the outflow of the water cut-off memberto outside due to crimping.

Wire with terminal

The present disclosure provides a connector device that is small and easy to manufacture, and that has excellent waterproof performance. The connector device includes a circuit board, a connector, and a molded resin portion. The circuit board has a conductor path. The connector has a housing containing a resin, and a terminal protruding from the housing and configured to be connected to the conductor path. The molded resin portion collectively covers the conductor path, the terminal protruding from the housing, and part of the housing. The housing and the molded resin portion have a welded portion where constituent materials are welded to each other.

Connector device that includes welded portion

A terminal-equipped wire in which a terminal fitting and a wire obtained by covering an outer periphery of a conductor with an insulating covering are electrically connected to each other at an electric connection, the terminal-equipped wire including a resin covering that is made of a resin material, and covers the electric connection, wherein: the resin covering includes, in a region that covers at least part of the terminal fitting, a first covering layer that is in contact with a surface of the terminal fitting and a second covering layer that covers at least part of the first covering layer, and the first covering layer has a recess, and the recess is covered by the second covering layer.

Terminal-equipped wire and wire harness

An anticorrosive agent including: a high-consistency material having a lubricant base oil and an amide compound, a composition of a phosphorus compound comprising one or more compounds represented by the general formulae (1) and (2) and a metal, and at least one kind of resin selected from a rosin-based resin, a terpene resin, a terpene phenol resin, a phenol resin, a coumarone-indene resin, and a petroleum resin, wherein a mass ratio of the high-consistency material and the composition is within a range of 50:50 to 98:2, and a content of resin is 2 to 20 parts by mass with respect to 100 parts by mass of the total of the high-consistency material and the composition.

Anticorrosive agent and terminal fitted electric wire

A terminal-equipped electrical wire that includes a terminal fitting; an electrical wire that includes a conductor surrounded by an insulation covering and is electrically connected to the terminal fitting in an electrical connection; and a resin cover that is made of a resin material and covers the electrical connection, wherein the resin cover is in contact with the terminal fitting and the insulation covering, a tensile shear adhesion strength between the resin cover and the terminal fitting is 1.0 MPa or higher, and a tensile shear adhesion strength between the resin cover and the insulation covering is 0.5 MPa or higher.

Cable with terminal formed therein and wire harness

A terminal-equipped wire that includes a terminal fitting; a wire including a conductor and a wire covering that covers an outer circumference of the conductor, the wire being electrically connected to the terminal fitting at an electric connection; and a resin covering that covers the electric connection and is in contact with the wire covering.

An anticorrosive agent maintains its anticorrosion property when the agent is applied to the connection part of the terminal-fitted electric wire containing a covering member containing a plasticizer, and is exposed to high temperature. A terminal-fitted electric wire improves in anticorrosion property by using the agent. The anticorrosive agent contains a base oil (A) having a viscosity of 30 mPa&#xb7;s or higher at 100&#xb0; C., and a metal adsorbent (B) containing a phosphorus compound. The mass composition ratio (A):(B) of the base oil (A) and the metal adsorbent (B) is within a range of 50:50 to 98:2. In the terminal-fitted electric wire, an electric connection part between a terminal and an electric conductor is covered with a film of the anticorrosive agent.

A terminal-equipped covered electric wire and a wire harness in which an electrical connection portion where a terminal fitting and an electric wire conductor are electrically connected is covered with a resin cover portion. With the terminal-equipped covered electric wire and the wire harness, the terminal fitting is prevented from being damaged during insertion into a connector housing, and the resin cover portion has improved adhesiveness to the terminal fitting. Provided is a terminal-equipped covered electric wire in which a resin cover portion covering an electrical connection portion includes a first layer made of a thermoplastic elastomer having adhesiveness to the surface of a terminal fitting, and a second layer made of a polyester resin. The adhesive strength between the thermoplastic elastomer and the polyester resin is 1.3 MPa or more. A wire harness including such a terminal-equipped covered electric wire is configured.

Terminal-equipped covered electric wire and wire harness

A terminal-equipped wire includes a wire with a core wire and an insulating coating with which the core wire is coated, and a terminal fitting that is attached to a leading end of the wire. The terminal fitting is electrically connected to the core wire in a core-wire crimp portion, and is fixed to the wire from an external side of the insulating coating in a coating crimp portion that is located rearward of the core-wire crimp portion in a longitudinal direction of the wire. The terminal-equipped wire also includes a resin-coated portion where a region containing the core-wire crimp portion and the coating crimp portion is coated with a resin. The resin-coated portion has a thin-walled portion with a reduced thickness, in a portion of the resin-coated portion that covers the insulating coating.
