Abstract

A conductor connection clamp is described that comprises a housing that is embodied from an insulating material and comprises at least one resilient force clamping connector in the housing that is embodied from an insulating material, and also comprises at least one actuating element that is received in a pivotable manner in the housing that is embodied from an insulating material, said actuating element being designed so as to open in each case at least one allocated resilient force clamping connector. The actuating element comprises two lever arm sections that are spaced apart from one another and protrude at least in part with a pivot bearing region into the housing that is embodied from an insulating material and are connected one to the other spaced apart with respect to the pivot bearing region by a transverse connecting piece to a lever arm. The at least one resilient force clamping connector is covered on the side of the housing that is embodied from an insulating material on which the at least one actuating element is arranged by an outer boundary wall of the housing that is embodied from an insulating material and extends from the outer boundary wall on both sides of lateral wall sections that are adjacent to a respective allocation resilient force clamping connector into the inner space of the housing that is embodied from an insulating material.

First claim

The invention claimed is:

1. A conductor connection clamp, comprising:
a housing embodied from an insulating material, the housing including at least one spring clamping connector, and at least one actuating element that is arranged in the housing in a pivotable manner, said actuating element being designed so as to open in each case at least one associated spring clamping connector,
wherein the actuating element comprises two lever arm sections spaced apart from one another, the respective lever arm sections arranged on opposite sides of the associated at least one spring clamping connector, and protrude at least in part with a pivot bearing region into the housing,
the two lever arm sections connected one to the other and spaced apart with respect to the pivot bearing region by a transverse connecting piece to a lever arm,
wherein on the side of the housing on which the at least one actuating element is arranged the at least one spring clamping connector is covered by an outer boundary wall of the housing, and
lateral wall sections of the housing that are adjacent on both sides to a respective associated spring clamping connector extend from the outer boundary wall into the inner space of the housing,
wherein when the respective actuating element is in the closed state pivoted downwards in the direction of the housing, the lever arm sections of the actuating element are adjacent to a respective associated lateral wall section that lies laterally adjacent to a spring clamping connector.

2. The conductor connection clamp as claimed in claim 1 , wherein the lateral wall sections that lie laterally adjacent to a spring clamping connector and extend from the outer boundary wall into the inner space of the housing terminate in a section that extends over a pivot bearing region of the associated actuating element and is adjacent to this pivot bearing region.

3. The conductor connection clamp as claimed in claim 1 , wherein the lateral wall sections that lie laterally adjacent to a spring clamping connector extend from the outer boundary wall into the inner space of the housing merge in a section that extends over the conductor insertion opening of the housing and is in the boundary walls of this conductor insertion opening.

4. The conductor connection clamp as claimed in claim 1 , wherein when the respective allocated actuating element is in the closed state in each case an elevated section of the housing protrudes into a free space of the actuating element, said free space being adjacent to the transverse connecting piece and being laterally defined by means of the lever arm elements.

5. The conductor connection clamp as claimed in claim 4 , wherein the elevated section abuts flush with the upper face of the adjacent section of the actuating element.

6. The conductor connector clamp as claimed in claim 1 , wherein when the respective allocated actuating element is in the closed state in each case a section of an outer boundary wall of the housing is arranged directly below the transverse connecting piece of the allocated actuating element in a free space that is formed by means of the transverse connecting piece and lever arm sections that are adjacent to said transverse connecting piece.

7. The conductor connection clamp as claimed in claim 6 , comprising an intermediate space between the outer boundary wall of the housing and an adjacent conductor insertion opening-boundary wall for a conductor insertion opening, said boundary wall lying directly below the transverse connecting piece of the allocated actuating element when the respective actuating element is in the closed state.

8. The conductor connection clamp as claimed in claim 7 , wherein an intermediate space of this type is open between the outer boundary wall of the housing and an adjacent conductor insertion opening-boundary wall in order to form an inspection opening on an opposite-lying side and an adjacent spring clamping connector is accessible for an inspection tool that is guided through the inspection opening by way of the intermediate space.

9. The conductor connection clamp as claimed in claim 1 , wherein at least one of the pivot bearing regions has an actuating contour that can be brought into engagement with a resilient clamping element of an allocated spring clamping connector as the actuating element is pivoted in order to open a clamping site of the spring clamping connector in order to clamp an electrical conductor, said clamping site being formed by means of a clamping edge of the clamping spring and a current rail section of a current rail.

10. The conductor connection clamp as claimed in claim 9 , wherein the current rail extends over at least two spring clamping connectors that are arranged adjacent one to the other in a row in order to connect electrical conductors one to the other in an electrically conductive manner, said electrical conductors being clamped to the at least two spring clamping connectors.
