A connector terminal () is formed by a connector joining portion () that is joined to a mating connector terminal, a connector bonding portion (A) that is bent from the connector joining portion (C) and extends along a surface of a board () and a movement stopper portion (P-C) that engages with a movement stopper part (E) provided at the board () and stops the connector bonding portion (A) from moving on the surface of the board (). In a state in which the connector bonding portion (A) is put on solder applied to the board (), the movement stopper portion (P-C) engages with the movement stopper part (E) of the board (), and the connector terminal () is bonded and fixed to the board () with melted solder.

Electrical drive device and electrical power steering device

An element-side connection terminal () extending from a power conversion circuit unit () includes a first connection terminal portion (A) that extends in a direction intersecting a direction of extension of a counterpart-side connection terminal (); and a second connection terminal portion (B) that is bent at a point before the first connection terminal portion (A) reaches the counterpart-side connection terminal () in a direction to intersect the direction of extension of the counterpart-side connection terminal () such that the second connection terminal portion (B) is provided with elasticity and is in an elastic contact with the counterpart-side connection terminal () at an angle. A tip end side (T) of the counterpart-side connection terminal () and a tip end side (T) of the second connection terminal portion (B) are electrically joined.

Electronic control device and electric drive device

The device has motor housing side annular engagement portionformed at outer circumferential surface of end surface portion of motor housingwhich is opposite side to output shaft portion of rotation shaft of electric motor; and metal cover side annular engagement portionformed at opening endof metal coverthat covers electronic control unit and engaged with motor housing side annular engagement portion. Fixing region is formed by fixing metal cover side annular engagement portionto motor housing side annular engagement portionin a fixing manner without using any fixing screw in a state in which metal cover side annular engagement portionis engaged with motor housing side annular engagement portion. Sealing region is formed between fixing region and opening endof the metal coverwith liquid sealantapplied between fixing region and opening end

Electric drive device and electric power steering device

An inverter device includes an inverter circuit, a control circuit, a first drive circuit, a second drive circuit, first and second photocouplers, and a signal switching part. The signal switching part directly transmits the first and second signals outputted from the first photocoupler and the second photocoupler to the corresponding first and second drive circuits respectively when at least one of the first and second signals is an OFF command.
