A conductor connection contact element for clamping an electrical conductor, having a power rail piece and a clamping spring. The power rail piece is formed from a sheet-metal part with an oppositely situated second side wall, a base section and an oppositely situated cover section. The side walls, together with the base section and the cover section, border a conductor insertion channel. The clamping spring is arranged on the power rail piece. The clamping spring has an abutment section and a clamping section with a clamping edge for clamping the electrical conductor. The abutment section is arranged on the base section of the power rail piece. The freely movable end of the clamping section extends toward the cover section. An actuation section which is accessible to an actuation tool lies adjacent to the clamping edge in the direction of the side wall.

Electrical wiring devices that incorporate clamp-type wire terminal connections are described. The electrical wiring devices include for example, single and duplex blade-type electrical receptacles, blade-type locking electrical receptacles, single or multi-pole electrical switches, combination switches and blade-type receptacles, blade-type plugs for electrical cords and blade-type connectors for electrical cords. The electrical wiring devices include a plurality of contact assemblies. Each contact assembly includes a wire terminal and a plunger.

A switch wire connection device has a simplified structure and is easy to operate with enhanced stability of operation. The switch wire connection device includes a conductive component mounted in an insulation case, a switch pushbutton assembled with the conductive component and an electrical contact. The electrical contact has a restriction unit and a contact plate connected with the restriction unit. By means of operating the pushbutton, the conductive component is driven to selectively electrically contact or separate from the contact plate. The restriction unit defines a space, in which a metal leaf spring is assembled. The wiring circuit or conductive wire of a machine or equipment can be easily directly plugged into the space of the restriction unit and held by the metal leaf spring. The metal leaf spring is prevented from deflecting in the operation process.

A terminal block includes a housing that has an opening through which a wire is to be inserted, a terminal configured to be connected to the wire that is inserted through the opening, and a plate spring member configured to fix the wire by pressing the wire against the terminal. The plate spring member has a pressing portion configured to press the wire against the terminal, and a plastic deformation preventing portion configured to prevent the pressing portion from bending in a direction away from the terminal by more than a predetermined amount.

A contacting device for bringing an electrical conductor into contact with an electrical conductor path includes a housing having a first opening for inserting the electrical conductor into a cavity in the housing and a second opening for inserting the electrical conductor path into the cavity in the housing, and a bow collector including a first portion, which is arranged in the cavity in the housing, and a second portion. The bow collector is designed such that the electrical conductor can be pressed against the electrical conductor path by the first portion of the bow collector after the electrical conductor and electrical conductor path have been inserted into the cavity in the housing, as a result of which the electrical conductor is retained on the electrical conductor path in a clamping position so as to be in contact with the electrical conductor path.

A set comprising a conductor connection terminal and an accessory element for fastening to the conductor connection terminal. The conductor connection terminal has a conductor connection for connecting an electrical conductor and has a conductor insertion channel for inserting and guiding the electrical conductor to the conductor connection. The conductor connection terminal has, in addition to the conductor insertion channel, an accessory insertion channel, in which the accessory element can be selectively fastened with a fastening section of the accessory element.

The present disclosure relates to an electrical contact assembly of a plug-in connection terminal, which has an electrical contact having a first connector element for connecting a plug-in contact in a plug-in direction, a second connector element for connecting an electrical conductor in a clamping manner being arranged on the electrical contact, the first connector element having at least one contact element that has at least one first section and one second section, the width of the first section at a right angle to the plug-in direction being greater than the width of the second section at a right angle to the plug-in direction.

A connector module for connecting the bare end of an insulated electrical conductor with an electrical device, including a hollow generally-rectangular terminal cage body formed from a bent conductive first metal sheet to form at least one vertical generally rectangular side wall and a pair of end walls, one of the cage walls having a horizontal lower surface defining a first cage sealing surface, and a vertical interior wall surface defining a second cage sealing surface; a horizontal bus bar formed from a conductive second metal sheet and having a relatively broad horizontal top surface defining a horizontal first bus bar sealing surface, and a relatively narrow side surface defining a vertical second bus bar sealing surface; and a securing seam for securing one of the bus bar first and second sealing surfaces with the corresponding one of the cage first and second sealing surfaces.

A wire connection terminal structure includes a leaf spring, a conductive plate and a fixing frame framing and connecting with the leaf spring and the conductive plate. The conductive plate is formed with a base section assembled with the fixing frame. The leaf spring is formed with an elastic swingable holding section extending to a position in contact with the base section. The holding section and the base section define therebetween an elastic holding mouth. An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.

A connector is connectable with a conductive core of a cable which is inserted from a front of the connector along a front-rear direction. The connector comprises a shell and a spring member. The shell is made of a metal. The shell has an operation portion and a contact portion. The spring member is made of another metal which is harder than the metal of the shell. The spring member has an operated portion and a press portion. When the operation portion moves the operated portion, the press portion is moved away from the contact portion. The press portion presses the conductive core against the contact portion under a connection state where the conductive core is connected with the connector.
