Spring force terminal
First Claim
1. A spring force terminal for connecting electrical conductors, having a contact frame, in which an electrical conductor can be clamped against the contact frame by means of a clamping spring extending in the form of an arc over the contact frame, wherein the contact frame has two or more plug openings and a retaining opening, wherein the clamping spring has a first free end and a second free end, and the clamping spring is fixedly restrained at the first free end in the retaining opening on the contact frame, wherein, at its second free end, the clamping spring is divided into a number of finger projections which corresponds to the number of plug openings by means of one or more slot cutouts and wherein each of the projections is passed through in each case one of the plug openings and a conductor can be clamped tightly in each of the plug openings by in each case one of the projections, and wherein an adjustment contact part is integrally formed on the contact frame, such that an acute angle is formed with each finger projection of the clamping spring and a funnel-shaped opening is realized.

Abstract
The invention describes a spring force terminal (1) for connecting electrical conductors (128), having a contact frame (3, 125), in which an electrical conductor (128) can be clamped against the contact frame (3, 125) by means of a clamping spring (7, 121) extending in the form of an arc over the contact frame (3, 125), and which is characterized in that the contact frame (3, 125) has two or more plug openings (9, 11, 124) and a retaining opening (13, 133), in that the clamping spring (7, 121) is held at a first free end in the retaining opening (13, 133) on the contact frame (3, 125), in that, at its second free end, the clamping spring (7, 121) is divided into a number of finger-like projections (23, 25, 122) which corresponds to the number of plug openings (9, 11, 124) by means of one or more slot-like cutouts (17), and in that each of the projections (23, 25, 122) is passed through in each case one of the plug openings (9, 11, 124), and a conductor (128) can be clamped tightly in each of the plug openings (9, 11, 124) by in each case one of the projections (23, 25, 122).
