Spring force connection terminal and plug connector

摘要

The invention describes a spring-three terminal connection (1) for the terminal connection of electrical conductors, having an insulating-material housing (2) which has at least one conductor insertion opening (12) for the insertion of an electrical conductor, at least one clamping spring (5) which has a contact limb (7), a clamping limb (10) and a spring bow (8) which connects the contact limb (7) and the clamping limb (10) to one another, and having at least one operating button (15) which is accommodated in the insulating-material housing such that it can be displaced and which has an operating area (14) for making contact with the clamping limb (10) and moving the clamping limb (10) in the direction of the contact limb (7) for opening the clamping point when the operating button (15) is displaced in the direction of the interior of the insulating-material housing (2). The insulating-material housing (2) contains at least one button opening (16) for accommodating an associated operating button (15), said button opening being open in the direction of an associated conductor insertion opening (12). The operating button (15), which is mounted in this button opening (16) such that it can be displaced, forms part of the wall arrangement of the conductor insertion opening (12). Starting from a mouth section (50) which adjoins the conductor insertion opening (12), the button opening (16) is widened in the direction of the hack (51) of the button opening (16), said back being situated opposite the conductor insertion opening (12). The cross section of the operating button (15) is matched to the widening contour of the button opening (16).

主权项

1. A spring-force terminal connection for clamping electrical conductors having:
an insulating-material housing that comprises at least one conductor inserting opening for inserting an electrical conductor, at least one clamping spring that comprises a contact limb, a clamping limb and a spring bow that connects the contact limb and the clamping limb to one another, and having at least one actuating lever that is received in a displaceable manner in the insulating-material housing and comprises an actuating surface for contacting the clamping limb and for displacing the clamping limb in the direction towards the contact limb so as to open the clamping site as the actuating lever is displaced in the direction towards the inner space of the insulating-material housing, characterized in that the at least one lever opening in the insulating-material housing for receiving an allocated actuating lever is open towards an allocated conductor inserting opening and that the actuating lever that is mounted in a displaceable manner in this lever opening forms part of the wall of the conductor inserting opening, wherein the lever opening becomes wider starting from an outlet section, which is adjacent to the conductor inserting opening, and leading to the back of the lever opening that is opposite the conductor inserting opening and wherein the cross section of the actuating lever is tailored to suit the widening contour of the lever opening.
