Circuit assembly and electrical junction box
A circuit assembly includes a busbar substrate with busbars and a resin part that is in intimate contact with the busbars, a press-fit member that is made of metal with a thickness greater than the thickness of the busbars, and is press-fitted in the busbar substrate, an electronic component connected to the press-fit member, solder that connects the busbars and the press-fit member, and a solder accumulating portion that is formed with the resin part, and in which the solder is accumulated.
1. A circuit assembly comprising:
a busbar substrate with a plurality of busbars arranged in different regions with gaps interposed therebetween and a resin part that is in intimate contact with upper and lower sides of the busbars, the resin part filling up the gaps between adjacent busbars;
a press-fit member that is made of metal and is press-fitted in the busbar substrate;
an electronic component connected to the press-fit member;
solder that connects the busbars and the press-fit member; and
a solder accumulating portion that is formed with the resin part and in which the solder is accumulated.
2. The circuit assembly according to claim 1 ,
wherein the resin part includes a protrusion portion that protrudes from an end edge of the busbar beyond the busbar, and the press-fit member is press-fitted to the protrusion portion.
3. The circuit assembly according to claim 2 , wherein the resin part has a press-fit hole into which the press-fit member is press-fitted.
4. The circuit assembly according to claim 1 , wherein the resin part has a press-fit hole into which the press-fit member is press-fitted.
5. An electrical junction box comprising:
the circuit assembly according to claim 1 ; and
a casing in which the circuit assembly is housed.
6. The electrical junction box as set forth in claim 5 , wherein the resin part includes a protrusion portion that protrudes from an end edge of the busbar beyond the busbar, and the press-fit member is press-fitted to the protrusion portion.
7. The electrical junction box as set forth in claim 5 , wherein the resin part has a press-fit hole into which the press-fit member is press-fitted.
