Abstract

The invention describes a spring-three terminal connection for the terminal connection of electrical conductors, having an insulating-material housing which has at least one conductor insertion opening for the insertion of an electrical conductor, at least one clamping spring which has a contact limb, a clamping limb and a spring how which connects the contact limb and the clamping limb to one another, and having at least one operating which is accommodated in the insulating-material housing such that it can be displaced and which has an operating area for making contact with the clamping limb and moving the clamping limb in the direction of the contact limb for opening the clamping point when the operating button is displaced in the direction of the interior of the insulating material housing. The insulating-material housing contains at least one button opening for accommodating an associated operating button, said button opening being open in the direction of an associated conductor insertion opening. The operating button, which is mounted in this button opening such that it can be displaced, forms part of the wall arrangement of the conductor insertion opening. Starting from the mouth section which adjoins the conductor insertion opening, the button opening is widened in the direction of the hack of the button opening, said back being situated opposite the conductor insertion opening. The cross section of the operating button is matched to the widening contour of the button opening.
