Terminals of the first and second busbars are spaced apart with the terminal of the third busbar between the first and third terminals. The third busbar includes a first region extending clockwise from its terminal and lying in the second plane and a second region extending counterclockwise from its terminal and lying in the first plane.

Linear drive with a gear housing extending along a longitudinal axis, in which a spindle is rotatably mounted with a worm wheel connected to it in a rotationally fixed manner, a spindle nut running on the spindle, which is adjustable on the spindle between a retracted position and an extended position and which acts on a lifting tube. The spindle nut is arranged in the retracted position guide tube and retracted in the region of a rear end of the guide tube, and thus the lifting tube is also retracted into the guide tube. The spindle nut is arranged at a front end of the guide tube in the extended position. An electric motor drives the screw, which extends along a transverse axis extending transversely to the longitudinal axis, wherein the electric motor is accommodated in a motor housing which is connected to the gear housing. Furthermore, a control system is arranged in a control housing. In order to simplify the assembly of the control housing, a connection is formed between the control housing and the drive housing, which is designed in such a way that the latter is simultaneously electrically connected to the drive housing during the mechanical attachment.

An electric apparatus including a connector holding six connecting terminals is provided. Three one-side connecting terminals held by the connector are arranged side by side in a row substantially directly below conductive terminals of three phases of one DC-AC converter. Three another-side connecting terminals held by the connector are arranged side by side in a row at positions offset to a side away from the one-side connecting terminals in an axial direction. Upper-end side connecting parts of the three one-side connecting terminals are set to be lower than upper-end side connecting parts of the three another-side connecting terminals, and are connected to the corresponding conductive terminals above via busbars extending in an up-down direction. The upper end-side connecting parts of the three another-side connecting terminals are connected to corresponding conductive terminals via busbars extending along an arrangement direction of the conductive terminals.

A rotating electric machine unit including a connector holding six connecting terminals is provided. When viewed from an axial direction, respective one-end parts of first to third connecting terminals are arranged side by side in a row. When viewed from the axial direction, respective one-end parts of fourth and fifth connecting terminals are arranged to offset to a back side of a first row composed of the first to third connecting terminals, and the one-end parts protrude further inside a casing than the one-end parts of the connecting terminals of the first row. When viewed from the axial direction, a one-end part of a sixth connecting terminal is arranged to offset to a back side of a second row composed of the fourth and fifth connecting terminals, and the one-end part protrudes further inside the casing than the one-end parts of the connecting terminals of the second row.

One aspect of the present disclosure provides a terminal block capable of improving mounting position accuracy. A terminal block according to the one aspect of the present disclosure includes a plate made of metal and to be fixed to a first case made of metal, a housing held on the plate, and a plurality of terminals held in the housing.
