A conductor rail module for distributing and a corresponding connection module for tapping a direct current distributed along a mounting rail is described. The connection module comprises a housing whose electrically insulating rear section is connected or connectable to the mounting rail in a form-fit manner. A front section of the housing has a plurality of electrically insulating transverse struts extending transversely to a longitudinal direction of the conductor rail module. Furthermore, the conductor rail module comprises at least two conductor rails extending in the longitudinal direction in the housing between the rear section and the front section, which conductor rails are configured to contact the connection modules for distributing the direct current through a gap between the transverse struts when the connection modules are in a position mounted on the conductor rail module.

A bolt terminal mounted on a guide rail is provided. The bolt terminal comprises a housing (1), an integral nut (2), a screw (3), a connection component (4), and a wiring metal surface (5); one end of the screw is provided in the housing, the other end of the screw is located outside the housing, and the screw located outside the housing is to be connected to the integral nut fitted therewith; the wiring metal surface is provided on the interface between the screw and the housing; and the housing is to be connected to the guide rail via the connection component. The bolt terminal increases the requirement for powering the wirings, and the bolt terminal can be removed from the guide rail only by using a conventional screwdriver to lightly tap on a removal port. The screw is integrally connected to the housing by injection molding and thus there is no risk of the screw falling off, enabling higher reliability.

A conductor connection terminal, having an insulating material housing, a busbar, a clamping spring and an operating lever which is pivotably received in the insulating material housing over a pivoting range and can be pivoted between an open position and a closed position, wherein the clamping spring has an operating arm which is deflected via a spring driver of the operating lever at least in the open position, characterized in that the operating lever is supported in the open position at a first and a second support point spaced from the first, and that the operating lever is pulled against the first and the second support point by a tensile force of the clamping spring acting on the spring driver from the operating arm.

A rail terminal assembling structure includes a protection member formed with an assembling passage defined by a contact side section, a connection side section and two lateral sections. The connection side section has a first locating section, an elastic locating section and a second locating section. An end section of a conductive plate extends into the assembling passage and securely attached to the contact side section. A metal leaf spring has a first section, a second section and an elastic bight section connected between the first and second sections. The first section has a first located section and an insertion section. When the first section extends into the assembling passage and the first section elastically pushes/presses the elastic locating section until the insertion section reaches the elastic locating section, the elastic locating section is elastically engaged with the insertion section.
