A busbar has a clamping section arranged between the inserted electrical conductor and the inserted contact element. A first clamping spring is provided for clamping the electrical conductor, which includes a first clamping leg having a clamping edge oriented in the direction of the clamping section, a first spring bend and a first contact leg, the clamping edge and the clamping section forming a first clamping point for clamping the electrical conductor. ## Claims ### Claim 1 A conductor terminal comprising: a housing that has a conductor insertion opening for inserting an electrical conductor and a contact element insertion opening for inserting a contact element; a busbar that has a clamping section arranged between the inserted electrical conductor and the inserted contact element; a first clamping spring to clamp the electrical conductor, the first clamping spring includes a first clamping leg having a clamping edge oriented in a direction of the clamping section, a first spring bend, and a first contact leg, the clamping edge and the clamping section forming a first clamping point for clamping the electrical conductor; and a second clamping spring that is a separate component from the first clamping spring, the second clamping spring including at least one second clamping leg to clamp the contact element, the second clamping leg being oriented in the direction of a contact section of the busbar so that a second clamping point for the contact element to be clamped is formed between the contact section and the second clamping leg. ### Claim 2 (depends on 1) The conductor terminal according to claim 1, wherein the busbar has a first bent section adjoining the clamping section, in which the busbar transitions in an arch-shaped manner directly into the contact section or via at least one further section of the busbar. ### Claim 3 (depends on 1) The conductor terminal according to claim 1, wherein the contact section is arranged essentially and/or predominantly in parallel to the clamping section. ### Claim 4 (depends on 1) The conductor terminal according to claim 1, wherein the first clamping spring is suspended by its first contact leg on an elongated holding section of the second clamping spring or on an elongated holding section of the busbar. ### Claim 5 (depends on 4) The conductor terminal according to claim 4, wherein the holding section runs orthogonally or predominantly orthogonally to the clamping section. ### Claim 6 (depends on 1) The conductor terminal according to claim 1, wherein the second clamping spring and the busbar are coupled with each other in a form-fitting manner. ### Claim 7 (depends on 1) The conductor terminal according to claim 1, wherein the second clamping spring includes a second contact leg, and wherein the second clamping leg and the busbar are coupled with each other in a form-fitting manner. ### Claim 8 (depends on 1) The conductor terminal according to claim 1, wherein the conductor terminal is a snap-on terminal and/or a luminaire terminal, which may be mounted with the contact element insertion opening on a contact element of an electrical device. ### Claim 9 (depends on 1) The conductor terminal according to claim 1, wherein the housing includes at least one main housing part and a cover part and a contact insert arranged in the housing, which includes at least the busbar, and wherein the cover part is fixed in the housing in interaction with the main housing part via the first clamping spring and the second clamping spring. ### Claim 10 (depends on 1) The conductor terminal according to claim 1, wherein the housing has a fixing area, which is configured to fasten a function element to the housing or to fasten the housing to a function element of this type. ### Claim 11 (depends on 1) The conductor terminal according to claim 1, wherein a contact element insertion channel adjoins the contact element insertion opening, which is at least partially formed by housing walls of the housing, the entire or a portion of the contact section and/or a portion of the second clamping spring being arranged behind a recessed area of the housing covered by the housing wall in the longitudinal direction of the contact element insertion channel, viewed from the contact element insertion opening. ### Claim 12 (depends on 1) The conductor terminal according to claim 1, wherein the first clamping leg and the second clamping leg are arranged on opposite sides of the busbar. ### Claim 13 (depends on 1) The conductor terminal according to claim 1, wherein the first clamping leg points in the direction of the busbar from a side, and the second clamping leg points in the direction of the busbar from another side, and wherein the first clamping leg and the second clamping leg extend toward each other. ### Claim 14 (depends on 1) The conductor terminal according to claim 1, wherein the first clamping leg and the second clamping leg are arranged on opposite sides of the busbar. ### Claim 15 (depends on 1) The conductor terminal according to claim 1, wherein the housing includes at least one main housing part and a cover part, and wherein the busbar extends through an opening, at which the main housing part and the cover part do not adjoin each other.
