Abstract

A bus bar subassembly adapted to connect a first circuit board and a second circuit board includes a first bus bar, a second bus bar and a first electrical connector. The first bus bar is electrically connected to the first circuit board. The second bus bar is electrically connected to the second circuit board. The first connector is electrically connected to the first bus bar and the second bus bar.

Claims (58)

1 . A bus bar subassembly adapted to connect a first circuit board and a second circuit board, comprising:

a first bus bar electrically adapted to be connected to the first circuit board, the first bus bar has a U-shaped structure including two side walls and a bottom wall connected to the two side walls, the two side walls adapted to be detachably electrically connected to the first circuit board;

a second bus bar electrically adapted to be connected to the second circuit board; and

a first connector detachably electrically connected to the bottom wall of the first bus bar, and electrically connected to the second bus bar.

2 . The bus bar subassembly according to claim 1 , wherein the first bus bar and the second bus bar are adapted to orient the first circuit board parallel to the second circuit board.

3 . The bus bar subassembly according to claim 1 , wherein a connection portion adapted to be removably attached to the first circuit board is provided at a free end of at least one of the two side walls.

4 . The bus bar subassembly according to claim 1 , wherein the first connector defines a first slot at least partially receiving the second bus bar.

5 . The bus bar subassembly according to claim 4 , wherein the first slot is adapted to be in electrical contact with the second bus bar in a sliding manner along a direction perpendicular to the first circuit board.

6 . The bus bar subassembly according to claim 5 , wherein the second bus bar has a L-shaped structure, including:

a first arm adapted to be detachably electrically connected to the second circuit board; and

a second arm perpendicular to the first arm and inserted into the first slot in an electrically contacting manner.

7 . An electrical assembly comprising:

a first circuit board;

at least one second circuit board; and

at least one first bus bar subassembly connecting to the first circuit board and the second circuit board, including:

a first bus bar electrically connected to the first circuit board;
