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: 20180226732Abstract: A connection housing includes a connection housing rear wall, at least one open area, and at least one connection device for a conductor. The connection device preferably has at least individual conductor connections. Each individual conductor connection has a metal contact element, a spring support which is made of a non-conductive material such as synthetic plastic, and includes a base wall and a clamping spring. The spring support is inserted into the open area such that the base wall lies parallel to the rear wall of the connection housing at a distance therefrom. The base wall forms a guide for conductors to be inserted, and the base wall completely or partly closes the housing towards the outside in the region of the open area.Type: ApplicationFiled: September 16, 2016Publication date: August 9, 2018Inventors: Karlo STJEPANOVIC, Stephan FEHLING, Constantin CLASSEN, Michael HERRMANN
