A terminal block includes: a terminal body with a screw hole for a screw used to connect a wire; and a terminal holder that holds the terminal body and has a substrate facing portion placed facing a first surface of a substrate. The terminal block is attached to the substrate by soldering the terminal body to a conductive pattern of the substrate with the substrate facing portion facing the first surface. The terminal holder has the substrate facing portion at one end in a first direction that becomes parallel to the thickness of the substrate when the terminal block is attached to the substrate. A casing fixing portion equipped with an insertion portion, into which a fastener for fixing the terminal holder to a casing that houses the substrate is inserted, is provided at another end in the first direction of the terminal holder.

An electrical connection of an electronic component, such as an inductor, and a circuit board is implemented as follows. The circuit board has a through-hole and is located at a distance from an inner bottom surface of the case. An electronic component is around the through-hole and between the inner bottom surface and the circuit board. The electronic component has a conducting wire and a conducting plate. The conductive connector is between the through-hole and the conducting plate and electrically connected to the conducting plate. The electronic component is electrically connected to the circuit board through the conductive connector. The insulated connector corresponds to the conductive connector and is between the conducting plate and the inner bottom surface. The fastener is connected to the conductive connector through the through-hole. Thus, a good electrical connection between the electronic component and the circuit board is achieved.

A terminal mounting structure includes a plurality of receive-side terminals, each of which extends from a distal end of each of electrical leads, a mounting stand that includes an electrically-insulating base and a plurality of supply-side conductive bars that are disposed at intervals and extend so as to pass through the base, a plurality of screws, each of which passes through the receive-side terminal in a direction crossing an extending direction of the receive-side terminal, each of which is screwed into a screw hole formed at an end part of the supply-side conductive bar so as to cause each of the receive-side terminals to contact each of the supply-side conductive bars and to fix each of the receive-side terminals to each of the supply-side conductive bars, and a contact prevention mechanism that is provided in the mounting stand so as to prevent adjacent receive-side terminals from contacting with each other.

A connector 10 includes a plurality of terminals 20 formed by a metal plate and extending in parallel to each other and a housing 40 made of resin for covering the plurality of terminals 20, and is mounted on a case 101 of a device 100. The terminal 20A, 20B, 20C includes a first extending portion 21A, 21B, 21C extending in a first direction Z and a second extending portion 22A, 22B, 22C extending from a part of the first extending portion 21A, 21B, 21C on a side opposite to the case 101 and to be connected to a wire 30. Plate thickness directions of a plurality of the first extending portions 21A, 21B and 21C coincide with each other. A plurality of the second extending portions 22A, 22B and 22C extend in a plane direction intersecting the first direction Z and orthogonal to the plate thickness directions.

A drive device includes: a drive unit including a rotary electric machine and a drive unit case that houses the rotary electric machine; a control unit including a control device configured to control the rotary electric machine; and a connection unit including a connection line that electrically connects the rotary electric machine and the control device. The control unit is disposed at a position facing the outer peripheral surface of the drive unit case. A space portion is provided between the outer peripheral surface of the drive unit case and the control unit. The connection unit is provided such that the connection line electrically connects the rotary electric machine and the control device through the space portion.

An output terminal for a vehicle AC generator is provided. The output terminal comprises: a bolt and a cylinder nut. The bolt has outer threads and is inserted through a through hole of a rectifier unit. The cylinder nut has inner threads, which engage with the outer threads of the bolt so that the cylinder nut surrounds the outer circumference of the bolt and fixes the bolt to the rectifier unit. The cylinder nut has a recess in its outer circumference. An insulating sleeve may be provided on the output terminal. The insulating sleeve has at least an internal protrusion for being received in and engaged with the recess of the cylinder nut.
