Abstract:
A spring loaded clamping connection for electrical conductors, comprising:a clamping spring which is made from a spring steel sheet and which is mounted on a free end of a current bar, punched out of a strip of flat material having good electrical conductivity,said clamping spring having a backward spring bow from which extends a contact leg which lies on the current bar, and a clamping leg which is bent in a shape of a loop with a free end of the clamping leg running crosswise to the free end of the current bar,the free end of the clamping leg having a window opening through which the free end of the current bar extends such that a clamping unit is formed between a lower edge of the window opening and an underside of the current bar, and further including an electrical conductor which is inserted between the lower edge of the window opening and the current bar and which is clamped to the underside of the current bar,the end part of the current bar on which the clamping spring is mounted, having two levels at different heights, namely an upper level adjacent the free end of the current bar that cooperates with the opening of the clamping leg to form said clamping unit,and a lower level adjacent, the contact leg of the clamping spring that lies on the current bar; anda spacer frame disposed between the upper level and lower level, the spacer frame being formed out of a part of the current bar to carry the upper level above the lower level, whereby said spacer frame is overlapped by the clamping leg of the clamping spring and is arranged with its fee-end into an inner space of the clamping spring,wherein in the upper level there is a platform which is bent from the spacer frame in the direction of the window opening of the clamping leg;whereby an end of said platform extends from inside said clamping spring through said window opening to outside said clamping spring in such a way that the clamping unit for an electrical conductor is formed between the underside of said platform and the lower edge of said window opening;and moreover, further including a wall opening in the spacer frame between the upper level and the lower level which allows an end of an electrical conductor clamped in the clamping unit to extend into the inner space of the clamping spring.
