A crimp terminal () includes a barrel () on which a recessed serration () is formed, the barrel is to be bent and crimped to a conductor portion () of a wire (), and the shape of an outer edge of the serration () is formed so that arcs (Ato A) each of which is convex outward continue to each other.

Crimp terminal

Provided is a bending rigid printed wiring board which facilitate the mounting of electric parts (realization of a high producibility and high assemblability substrate circuit) and enables spaces to be saved and which can be easily manufactured. That is, provided is a bending rigid printed wiring board, which is characterized in that a heat resistant resin layer is laminated on a front surface of a hard core material provided so as to contain a gap portion and also on a top surface of the gap portion, in that a heat resistant resin layer is laminated on a rear surface of the core material except the gap portion, in that a conductor layer is laminated and firmly fixed via the heat resistant resin layers and in that the conductor layer is etched, whereby a circuit is formed.

Method of manufacturing a rigid printed wiring board

The junction box housing of a junction box is provided with a strip portion containing portion which contains a lateral edge of a strip portion where a terminal connecting portion of a flexible printed circuit is contained in the inside and a terminal containing hole arranged at the outside of the strip-shaped portion containing portion which contains a first connecting terminal. Thus, the first connecting terminal and the strip portion can be contained in the junction box housing with the terminal connecting portion bent to show an S-shaped profile so that the junction box main body can be made lightweight and low-profiled to realize downsizing.

Junction box and connector

A conductive pattern made of copper foil is formed on a base material in each of a plurality of laminated flexible printed circuit boards, and a land is formed to expose the conductive pattern at a predetermined position in the base material. The plurality of flexible printed circuit boards are laminated to adjust each land, and the conductive pattern of each flexible printed circuit board is connected through the each land.

Interlayer connection structure of multilayer wiring board, method of manufacturing method of forming land thereof

There is disclosed a junction box including a junction box main body to which an electric component to be connected is attached, a connector portion, formed separately from the junction box main body, for connecting a connector of an outer wiring circuit, and a cable portion which includes a flexible printed circuit with a circuit portion including a conductor pattern formed on an insulating film, and electrically connects the junction box main body to the connector portion. With respect to an attachment position of one of the connector portion and junction box main body, an attachment position of the other can freely be changed.

Junction box, connector, and connecting terminal for use in the box and connector

There is disclosed a junction box including a junction box main body, a connector portion, and a cable portion which connects the junction box main body to the connector portion. Terminal connecting portions are formed to extend from opposite side edges of a strip portion of a flexible printed circuit constituting the cable portion in a short direction of the strip portion, and are connected to first to third connecting terminals. The third connecting terminal is connected to a desired connecting terminal connecting portion of a circuit distribution wiring circuit of a joint connector, electricity is conducted through a plurality of circuit portions in a desired circuit mode, and a wiring design freedom degree is enhanced.

Junction box

A junction between the portion of wiring of an FPC, which is not covered with a cover layer, is directly connected to a connection plate tip incorporated in a terminal attachment by one of resistance welding, ultrasonic welding and laser welding.
