Abstract
An electrical connection terminal having a holder and a clamping lever pivotably arranged on the holder and having a clamping unit for clamping a conductor between the clamping unit and a current bar. A manual lever is provided which is pivotably accommodated on the clamping lever in order to enable a dynamic transformation ratio in the closing operation.
Claims14
An electrical connection terminal comprising a holder and at least one clamping lever which is arranged pivotably on said holder and has at least one clamping unit for clamping at least one conductor between the clamping unit and a current bar,
- wherein
- a manual lever is provided, said manual lever being accommodated pivotably on the clamping lever in order to permit a dynamic transmission ratio during the closing operation and a high clamping force
- wherein
- an auxiliary lever is provided, said auxiliary lever connecting the manual lever pivotably to the holder.
An electrical connection terminal comprising:
- a holder;
- at least one clamping lever which is arranged pivotably on said holder;
- and;
- at least one clamping unit for clamping at least one conductor between the clamping lever and a current bar,
- wherein the at least one clamping unit comprises:
- a manual lever pivotably connected to the clamping lever;
- and
- an auxiliary lever pivotally connecting the manual lever to the holder, forming a 4-bar linkage in combination with the manual lever, the clamping lever and the holder;
- wherein the 4-bar linkage can toggle between a clamped state with the clamping lever elastically biased toward the current bar, when the manual lever is in a lowered position, and a unclamped state when the manual lever is in a raised position, resulting in an a dynamic transmission ratio during the closing operation and a high clamping force.
