Electric Circuit Apparatus and Method for Producing Electric Circuit Apparatus
First Claim
1. An electric circuit apparatus comprising:
- an electric circuit component including a DC terminal;
a power board configured to transfer a direct current, the power board including a positive electrode plate and a negative electrode plate sealed by a resin sealing material, which has an insulation property, in such a manner that a connection terminal part is exposed; and
a flexion member which is connected via a metal joining member having a melting point lower than those of the DC terminal and the connection terminal part, and which holds the DC terminal and the connection terminal part.

Abstract
An electric circuit apparatus includes a power module (300) including a DC positive electrode branch terminal (315D) and a DC negative electrode branch terminal (319D), and a power board (700) which is configured to transfer a direct current and which includes a power board P bus bar and a power board N bus bar sealed by a resin member, which has an insulation property, in such a manner that a P terminal (701) and an N terminal (702) are exposed. The DC positive electrode branch terminal (315D) and the P terminal (701) are held by a flexion member (904) and are connected to each other via a metal joining member having a melting point lower than those of the both terminals. The DC negative electrode branch terminal (319D) and the N terminal (702) are connected to each other in a similar manner. Thus, a thermal influence on the resin member can be reduced and connection durability can be improved.

7. A method for producing an electric circuit apparatus including an electric circuit component which includes a DC terminal, and a power board which is configured to transfer a direct current and which includes a positive electrode plate and a negative electrode plate sealed by a resin sealing material, which has an insulation property, in such a manner that a connection terminal part is exposed, the method comprising:
-
a first step in which a leading end part of the connection terminal part and a leading end part of the DC terminal are held integrally by a flexion member in a state in which a metal joining member having a melting point lower than those of the connection terminal part and the DC terminal is arranged therebetween; and a second step in which the connection part and the terminal are connected to each other by melting the metal joining member and solidifying the metal joining member again. - View Dependent Claims (8, 9, 10)
