A spring terminal for connection of an electrical conductor including a bus bar, a clamping spring; a housing; and a lever. The bus bar and the clamping spring and the lever are accommodated at least partially in the housing. The lever has a first support disk with a first partially circular outer contour for supporting the lever in a first bearing shell. The lever has a second support disk with a second partially circular outer contour for supporting the lever in a second bearing shell. The second support disk is spaced apart from the first support disk. The lever has an operating handle that is connected to the first support disk and to the second support disk. The clamping spring has a clamping leg that forms a clamping point with the bus bar for clamping the electrical conductor to the bus bar.

This module for electrically connecting conductors comprises an electrically insulating body comprising means for removably fastening the body in a cavity of a sub-mount and means for mechanically fastening and electrically connecting conductors. It includes, for each conductor, an electrically conductive insert inserted into the body and comprising releasable means for mechanically fastening and electrically connecting the conductors and in that the electrical connection tabs of the module are secured to the insert.

A joint connector includes: a bus bar having a plurality of male terminals; a plurality of female terminals electrically connected to the plurality of male terminals; a housing having a cavity receiving the bus bar and the plurality of female terminals; and a seal block having a plurality of receiving holes and contacting the housing, wherein each receiving hole receives an electrical wire connected to each female terminal.

A modular electrical bus system for a valve manifold has a main communication module with a plurality of modular I/O units each having a plurality of I/O fittings being both electrically and mechanically connectable together via a bridge member connecting adjacent units and the main communication module. At least one of the modular I/O units is also mechanically separable from and maintains communication connection to the main communication module. One or both of the modular .[.IO.]. .Iadd.I/O .Iaddend.units and main communication module may have an alpha-numeric display.

A spring-force connection having a housing part, a pivot lever, an electrically conductive connecting device and a contact spring by means of which a conductor (L) can apply force to the connecting device. The contact spring can be pivoted between release and clamping positions and has a pressing and a clamping limb, connected to the pressing limb using a bending joint. The pivot lever has a driver and the pressing limb is arranged between the pressing device and the driver in the closed position of the pivot lever and, by pivoting the pivot lever into its closed position, the pressing device can indirectly apply force to the pressing limb so that the contact spring is pivoted into its clamping position, so that the conductor applies force to the connecting device with the clamping limb and, by pivoting the pivot lever into its open position, the driver can indirectly apply force to the pressing limb so that the contact spring is pivoted into its release position.

An I/O device includes an I/O base, at least two I/O modules supported on the I/O base, and a duplex terminal block assembly supported on the I/O base. The at least two I/O modules include a first I/O module and a second I/O module coupled to the duplex terminal block assembly in parallel.
