Circuit connection device, rotating electric device, and circuit connection device manufacturing method

A method of manufacturing a circuit connection device wherein the circuit connection device includes:

• a connector having connection terminals that are connected to an outside of the circuit connection device, and press-fit terminals that are connected to the connection terminals;
• a circuit board that has terminal through holes formed, and the press-fit terminals are press-inserted into the terminal through holes;
• a terminal alignment member having a terminal guide that has guide through holes formed, where the guide through holes guide the press-fit terminals towards the terminal through holes, and the terminal alignment member is fixed to the circuit board while being disposed between the connector and the circuit board, and a heat sink that has an opening which houses the terminal guide on an inside of the opening, and the opening penetrates from a first surface to a second surface, where the circuit board is fixed to the first surface, and the connector is connected to the second surface that is on an opposite side of the first surface, wherein first positioning protrusions are formed on one of the connector or the heat sink, and first positioning recesses that mate with the first positioning protrusions are formed on the other of the connector or the heat sink, second positioning protrusions are formed on one of the circuit board or the terminal alignment member, and second positioning recesses that mate with the second positioning protrusions are formed on the other of the circuit board or the terminal alignment member, and third positioning protrusions are formed on one of the heat sink or the terminal alignment member, and third positioning recesses that mate with the third positioning protrusions are formed on the other of the heat sink or the terminal alignment member, the manufacturing method comprises:
• a first step of mating the second positioning protrusions with the second positioning recesses, and of fixing the terminal alignment member to the circuit board;
• a second step of mating the third positioning protrusions with the third positioning recesses, of housing the terminal guide on an inside of the opening, and of fixing the terminal alignment member to the heat sink, and
• a third step of mating the first positioning protrusions with the first positioning recesses, of inserting the press-fit terminals into the guide through holes while press-fitting the press-fit terminals into the terminal through holes, and of fixing the connector to the heat sink.
