Abstract

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.

Dependent claims

A structure for attaching a circuit board terminal to a circuit board, comprising:

a circuit board provided with a predetermined circuit section;
a holding member made of an insulation material and mounted on and secured to the circuit board;
a bus bar made of a metallic material and having a base portion supported on the holding member and a leg portion that passes a through-hole formed in the holding member and the circuit board to be soldered on the 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;
wherein the bus bar is provided on the base portion with a slit portion adapted to receive an end of the circuit board terminal and with an elastic tongue piece adapted to elastically contact with the circuit board terminal, and wherein when the circuit board terminal is inserted into the slit portion, the circuit board terminal is connected through the bus bar to the circuit section of the circuit board.
