Patent number: 12021339Abstract: 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.Type: GrantFiled: April 23, 2020Date of Patent: June 25, 2024Assignee: Weidmüller Interface GmbH & Co. KGInventors: Stephan Fehling, Karlo Stjepanovic, Walter Hanning, Heike Schmidtpott

Patent number: 11552413Abstract: 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.Type: GrantFiled: March 17, 2022Date of Patent: January 10, 2023Inventors: Stephan Fehling, Michael Herrmann, Walter Hanning, Constantin Classen

Publication number: 20220416449Abstract: 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.Type: ApplicationFiled: November 26, 2020Publication date: December 29, 2022Inventors: Stephan FEHLING, Walter HANNING, Michael HERRMANN, Heike SCHMIDTPOTT, Andreas RUTZ, Michael LENSCHEN, Karlo STJEPANOVIC
