Abstract

A connection terminal having at least one busbar piece and at least one clamping spring. The connection terminal has at least one spring-force clamping connection formed from a clamping spring and a portion of a busbar piece, an insulating-material housing including at least one conductor insertion opening which leads to an spring-force clamping connection and extends in a conductor insertion direction, and at least one pivotably mounted operating lever designed to interact with at least one clamping spring in order to open at least one spring-force clamping connection. The operating lever can be arranged with its rotation axis in the conductor insertion opening or in the path of the conductor insertion opening in the direction of the clamping point. The connection terminal provides a space-saving and compact construction, which is also improved in respect of the force effect of the operating lever.

Claims11

Dependent claims

A Connection terminal, comprising:

at least one busbar piece;
at least one clamping spring;
at least one spring-force clamping connection, which is formed from the clamping spring and a portion of the busbar piece, in order to clamp an electrical conductor at a clamping point between a clamping portion of the clamping spring and the busbar piece portion;
an insulating-material housing which has at least one conductor insertion opening which leads to the associated spring-force clamping connection and extends in a conductor insertion direction;
at least one pivotably mounted operating lever which is designed to interact with the at least one clamping spring by means of an operating portion in order to open the at least one associated spring-force clamping connection when the operating lever is pivoted;
and
an operating arm which adjoins the operating portion, wherein the rotation axis of the operating lever is arranged transverse to the conductor insertion direction in an associated conductor insertion opening or the extension of the conductor insertion opening which continues in the conductor insertion direction to the clamping point.
