• the first electrical terminal including a first busbar, a first spring clamp and a first blade arrangement, the first blade arrangement having at least a first blade which adjoins a first cutting groove having a groove base, the first blade arrangement being arranged in an inclined manner with regard to a plug-in axis, the first spring clamp including a first conductor feed-through section with a first recess and a first pressure bar, the first pressure bar being arranged between a free end of the first conductor feed-through section and the first recess, the first busbar being connected to the first blade arrangement and to the first spring clamp, the first spring clamp being bent at least between a first spring shape and a second spring shape differing from the first spring shape, wherein in the second spring shape, the first spring clamp is tensioned and the first pressure bar is arranged at a second minimal distance to the first cutting groove, and wherein in the first spring shape, the first spring clamp is tensioned in a reduced manner compared to the second spring shape and the first pressure bar is arranged closer to the first cutting groove than in the second spring shape;
• the second electrical terminal including a second busbar, a second spring clamp and a second blade arrangement, the second blade arrangement having at least a second blade which adjoins a second cutting groove having a groove base, the second blade arrangement being arranged in an inclined manner with regard to a plug-in axis, the second spring clamp including a second conductor feed-through section with a second recess and a second pressure bar, the second pressure bar being arranged between a free end of the second conductor feed-through section and the second recess, the second busbar being connected to the second blade arrangement and to the second spring clamp, the second spring clamp being bent at least between a first spring shape and a second spring shape differing from the first spring shape, wherein in the second spring shape, the second spring clamp is tensioned and the second pressure bar is arranged at a second minimal distance to the second cutting groove, and wherein in the first spring shape, the second spring clamp is tensioned in a reduced manner compared to the second spring shape and the second pressure bar is arranged closer to the second cutting groove than in the second spring shape;
• wherein the connecting busbar connects the busbar of the first electrical terminal to the busbar of the second electrical terminal,
• wherein the busbar of the first electrical terminal, the busbar of the second electrical terminal and the connecting busbar are formed in one piece and from one material.

A system comprising:

• an electrical terminal including a busbar, a spring clamp and a blade arrangement;
• and
• an electrical cable including an electrically conductive conductor and a cable insulation electrically insulating the first electrical conductor;
• wherein the blade arrangement has at least a first blade which adjoins a cut-ting groove having a groove base,
• wherein the blade arrangement is arranged in an inclined manner with regard to a plug-in axis,
• wherein the spring clamp comprises a conductor feed-through section with a first recess and a pressure bar,
• wherein the pressure bar is arranged between a free end of the conductor feed-through section and the first recess,
• wherein the busbar is connected to the blade arrangement and to the spring clamp,
• wherein the spring clamp is bent at least between a first spring shape and a second spring shape differing from the first spring shape,
• wherein in the second spring shape, the spring clamp is tensioned and the pressure bar is arranged at a second minimal distance to the cutting groove,
• wherein in the first spring shape, the spring clamp is tensioned in a reduced manner compared to the second spring shape and the pressure bar is arranged closer to the cutting groove than in the second spring shape,
• wherein the electrical cable extends through the first recess and the cutting groove,
• wherein the first blade engages through the cable insulation and contacts the electrical conductor,
• wherein the pressure bar secures the electrical cable in the cutting groove.

A method of assembling a system comprising:

• providing an electrical terminal including a busbar, a spring clamp and a blade arrangement, wherein the blade arrangement has at least a first blade which adjoins a cutting groove having a groove base, the blade arrangement being arranged in an inclined manner with regard to a plug-in axis, wherein the spring clamp includes a conductor feed-through section with a first recess and a pressure bar, the pressure bar being arranged between a free end of the conductor feed-through section and the first recess, wherein the busbar is connected to the blade arrangement and to the spring clamp, wherein the spring clamp is bendable at least between a first spring shape and a second spring shape differing from the first spring shape, wherein in the second spring shape, the spring clamp is tensioned and the pressure bar is arranged at a second minimal distance to the cutting groove, and wherein in the first spring shape, the spring clamp is tensioned in a reduced manner compared to the second spring shape and the pressure bar is arranged closer to the cutting groove than in the second spring shape;
• providing an electrical cable including an electrically conductive conductor and a cable insulation electrically insulating the first electrical conductor;
• introducing a tension force into the spring clamp to bend and tension the spring clamp into the second spring shape;
• routing the electrical cable through the first recess along the plug-in axis next to the blade arrangement;
• releasing the tension force such that the spring clamp relaxes and the pressure bar presses the electrical cable into the cutting groove, penetrating the first blade through the cable insulation to electrically contact the electrical conductor.
