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.
