Wind turbine blade, wind turbine, method for fabrication of a wind turbine component and method for fabrication of a wind turbine blade

A method for fabrication of a wind turbine blade component comprising:

• providing at least one panel core, at least one first laminate layer, at least one second laminate layer and at least one connection terminal element;
• arranging the at least one connection terminal element in a corresponding opening of the at least one panel core;
• arranging the first laminate layer and the second laminate layer on two opposing sides of the at least one panel core embedding the at least one connection terminal element at least partly, wherein the at least one connection terminal element comprises at least one unitary first connection portion located between the first laminate layer and the second laminate layer and directly connected to an embedded electrical conductor embedded between the first laminate layer and the second laminate layer, wherein on at least one side of the at least one connection terminal element, the at least one unitary first connection portion is arranged between two second connection portions or at least one second connection portion is arranged between two first connection portions;
• and
• casting the wind turbine blade component.

A wind turbine blade comprising:

• at least one laminate structure;
• and
• at least one unitary connection terminal element comprising a first connection portion and at least one second connection portion directly adjacent the first connection portion;
• wherein the at least one laminate structure comprises a panel core, at least one first laminate layer, and at least one second laminate layer, the panel core being embedded between the at least one first laminate layer and the at least one second laminate layer;
• wherein the at least one unitary connection terminal element is arranged in a corresponding opening of the panel core between the at least one first laminate layer and the at least one second laminate layer, the first connection portion being located between the at least one first laminate layer and the at least one second laminate layer and directly connected to an embedded electrical conductor embedded in the at least one laminate structure and the at least one second connection portion being adapted to be connected to at least one further electrical conductor arranged outside of the at least one laminate structure.
