In a structure for attaching a circuit board terminal to a circuit board, stress is minimized in a soldered portion on a circuit section upon inserting and drawing an electrical element into and from the circuit board. The attaching structure including a holding member mounted on and secured to a circuit board, a bus bar that has a base portion supported on the holding member and a leg portion that passes one or more through-holes and to be soldered on a circuit section, and a circuit board terminal that has a base portion to be connected to the bus bar and a connection portion adapted to be coupled to a terminal of an electrical element. The bus bar is provided on the base portion with elastic tongue pieces that can contact elastically with a circuit board terminal. The circuit board terminal is connected through the bus bar to the circuit section.

Structure for attaching a terminal to a circuit board

A joint connector (JC) has housings ( ) with chambers ( ) therein. Insertion openings ( ) and outlets ( ) extend into each chamber ( ) at the front end of the housing ( ). Terminal fittings ( ) are inserted into chambers ( ) so that joints ( ) of the terminal fittings ( ) project forward through outlets ( ). A cover ( ) is detachably mounted on each housing ( ) to protect the joints ( ). Insertion holes ( ) and insertion paths ( ) are formed in the cover ( ) and align with the insertion openings ( ) of the housing ( ). A probe ( ) can be inserted through the insertion holes ( ) and the insertion paths ( ) for contacting the terminal fittings ( ) so that an electrical connection test can be performed.
