Abstract: A spring-loaded terminal is designed as a direct plug-in terminal for connecting a conductor. The terminal includes a busbar for contacting the conductor, a clamping spring for retaining the electrical conductor in the terminal, and a retaining spring for latching the clamping spring in an open position so that the conductor can be inserted into a contact area. The clamping spring has a pivotable clamping leg and a clamping edge. The retaining spring has a pivotable pivoting leg having at least one retaining device as a first latching device. The clamping leg has a corresponding latching device cooperating with the retaining device of the pivoting leg in a latching state of the clamping leg. The clamping leg is adjustable from the latching state by displacing the electrical conductor into a clamping state in which the clamping leg is unlatched from the retaining device and presses the electrical conductor with the clamping edge of the clamping leg against the busbar.

Abstract: A spring terminal, in particular a direct plug-in terminal, for connecting a conductor such as a flexible stranded conductor includes a housing with a chamber and an insertion channel for inserting the conductor into the chamber. A busbar and/or a clamping cage are arranged in the housing and a clamping spring is arranged in the chamber and acts as a pressure spring. The clamping spring includes a clamping limb, said clamping limb releasable out of a latching state by a pusher having a latching edge on which the pusher can be latched in the interior of the housing on a latching hook of the busbar or another element arranged in the housing in a latching state. The pusher holds the clamping spring in a latched manner in the open position, wherein the latching edge of the pusher can be released from the latching state by an opposite movement.

Abstract: A spring force terminal such as a direct plug-in terminal for connecting a flexible stranded conductor includes a housing having a chamber and a plug-in channel for the conductor into the chamber. A busbar or a clamping cage are provided and a clamping spring arranged in the chamber acts as a compression spring for fixing the electrical conductor on the busbar or the clamping cage in the region of a clamping point. The clamping spring has a clamping leg pivotable around a pivot axis, which is adjustable from a latching state in which it is latched in a latching position into a clamping state in which it is unlatched from the latching position and presses the electrical conductor against the busbar or the clamping cage. The latching state is produced by pressing on the clamping leg in the conductor insertion direction using a pusher wherein the clamping leg is releasable from the latching state using two different actuatable adjustment devices.

Abstract: A direct clamp terminal for connecting a conductor in the form of a flexible stranded conductor includes a housing with a chamber and an insertion conduit for inserting the conductor into the chamber. A bus bar or a clamping cage is provided in the housing and a clamping spring is located in the chamber and acts as a compression spring for securing the electrical conductor to the bus bar or the clamping cage in the area of a clamping point. The clamping spring has a clamping limb that can be pivoted about a pivoting axis and that can be shifted from a detent mode in which it is locked in a detent position into a clamping mode in which it is released from the detent mode and presses the electrical conductor against the bus bar or the clamping cage. The clamping limb can be released from the detent mode using two different shifting devices.

Abstract: A connection device for conductors has at least one double conductor connection for connecting two conductors. The conductor connections are formed as direct plug connections each having a metal clamping cage formed of a highly conductive material such as sheet metal. A clamping spring is mounted on each clamping cage. Each clamping cage serves as a spring support for a clamping spring and as a contact element for each conductor.

At least one foot member is connected for horizontal longitudinal sliding movement relative to one of the base body corner portions relative to the adjacent support rail horizontal flange portion. A lateral displacement arrangement on the foot member is operable, when the foot member is displaced from a locked position toward an unlocked position relative to the support rail, to displace the first base body laterally away from an adjacent second base body mounted on the support rail. The foot member is latched in either a locked or an unlocked position relative to the base member.
