A conductive component structure of rail-type terminal device includes a conductive component disposed in an insulation case body. The conductive component has a first section and a second section connected with the base section. The first section and the second section are respectively formed with a bow portion, a first portion and a second portion. A load arm and an elastic unit assembled with the load arm are disposed on the first section and/or the second section. The elastic unit includes a first elastic section and a second elastic section. The load arm passes through the first elastic section and at least a part of the second elastic section. When the load arm is displaced or moved, the first elastic section and the second elastic section respectively provide tension (or pushback force) and pulling force effect so as to improve the shortcoming of the conventional terminal device.

A conductive pin configured for a quick connection system. The conductive pin has a non-conductive head and a conducting shaft with a conductive shaft bottom contact point. Beneath the head are a plurality of conducting contact arms in a X-configuration, each arm at a right angle to the next and separate to an adjacent conducting contact arm. The conducting shaft has a partial non-conductive sheath below the head. Rotating the conducting contact arms to contact points by rotating the conductive pin completes the circuit in the quick connection system.

An extendible electrical socket includes: a mother socket connected to a power supply source; and a plurality of daughter sockets which are connectable with one another to be an extendible electrical socket adapted for simultaneously connecting a plurality of electrical devices; each daughter socket including a locking device to be safely engaged with the mother socket or engaged with another or neighboring daughter socket to prevent from their disconnection when coupled and locked by each locking device.

A terminal block has an insulator housing, at least two busbars and at least four connection elements, there being at least two connection levels in the insulator housing arranged one over the other. Each connection level has a busbar receptacle chamber for receiving a busbar and two mutually opposite conductor connection chambers on ends of chamber for receiving a respective connection element, the chambers being open on an insulator housing first side for busbar assembly in the chambers and wherein the conductor connection chambers are open on a second side of the insulator housing for assembly of the connection elements in the conductor connection chambers. The insulator housing first side is designed at a right angle to the insulator housing second side to give an busbar assembly insertion direction into a chamber at a right angle to a connection element assembly insertion direction into a conductor connection chamber.

Provided is an electrical connection cassette with which it is possible to freely expand a device and add functions in accordance with the size of free space. An electrical connection cassette is provided with: a circuit board; and first connection terminals and second connection terminals mounted on the circuit board and having terminal shapes that can be engaged with each other. In a state with a terminal connection direction oriented in a predetermined direction with respect to the circuit board, the first connection terminals are disposed on the side of one main surface of the circuit board, and in a state with a terminal connection direction oriented in a direction parallel to the predetermined direction, the second connection terminals are disposed near the other main surface of the circuit board.

An example terminal block may include a frame that is to attach to a power supply casing. The frame may be formed from an electrical insulator, and may include a base, exterior walls connected to the base, and a number of interior walls that separate an interior region of the frame into multiple compartments. The example terminal block may include a cover that may be formed from an electrical insulator and may be connected to the frame such that the cover may transition between an open position and a closed position. Each of the compartments may electrically isolate bus bars from one another, where the bus bars extend from within the power supply casing into the frame. The base may include a nut holder in each of the compartments, each of the nut holders having a cavity formed therein that is shaped so as to hold a nut captive.

The present invention has advantages of high connection density, ease of wiring connection, high efficiency, being shock-resistant, loosening-proof and reliable, while meeting the IEC 60603-2 standard.

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.

A first case is integrally provided with a connection housing open to a side of the first case. A second case is integrally provided with a support base projecting toward the first case and facing inside the connection housing from a window provided in the connection housing. A bus bar included in a connection terminal disposed inside the connection housing is provided along the support base and is interposed between the support base and the first case, and is positioned in a projecting direction of the connection terminal.

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.
