Connection structure for a wiring member
View Patent ↗There is provided a structure for connecting a wiring member to a bus bar in which smooth connection is enabled while ensuring high reliability. In an end portion of a bus bar, a soldering portion which is smaller in cross-sectional area than the bus bar is formed. A connection projecting piece which is raised up in a pin-like manner is formed on the soldering portion. The connection projecting piece is passed through a connection hole which is formed in a connection end of a branch wiring portion of a wiring member configured by a flexible printed circuit board. The connection projecting piece which is passed through the connection hole is soldered to a circuit pattern.
1. A connection structure for a wiring member,
wherein a soldering portion is formed in an end portion of a bus bar, the soldering portion being smaller in cross-sectional area than the bus bar,
wherein the soldering portion includes an opening formed by a frame portion formed of the bus bar,
wherein a projecting piece which is raised up in a pin-like manner is formed at a portion of the frame portion in the soldering portion,
wherein the projecting piece is passed through a hole portion of the wiring member, the wiring member being configured by a flexible printed circuit board, and
wherein the projecting piece which is passed through the hole portion and a circuit pattern of the wiring member are soldered to each other.
2. The connection structure for the wiring member according to claim 1 ,
wherein the soldering portion is formed with an opening.
3. The connection structure for the wiring member according to claim 1 , wherein the bus bar is configured by stacking two plate portions on each other, and the soldering portion is formed in one of the plate portions.
4. The connection structure for the wiring member according to claim 1 , wherein the bus bar is configured by stacking two plate portions on each other, the soldering portion is formed in one of the plate portions, and the bus bar is formed from a bus bar coupled member which is formed in a chain-like manner by punching a metal plate, and
wherein the soldering portion is formed in a clearance space in the bus bar coupled member.
5. The connection structure for the wiring member according to claim 1 , wherein the bus bar is linked to at least one additional bus bar in a chain-like manner.
