Soldering aid for connecting a cable to a printed circuit board, comprising: - an electrically insulating body having a first cutout, a second cutout and a third cutout; and - an electrically conductive contact structure, which is coupled to the body, wherein the contact structure ∘ is in part embedded into the body in order to be connected to a litz wire of the cable in the interior of the body, and ∘ in part exits from the body in order to be connected to a connection of the printed circuit board; wherein the first cutout for receiving an end piece of the cable has a first section for a non-stripped portion of the cable end piece, wherein the stripped portion of the cable end piece comprises the litz wire, characterized in that the first cutout for receiving the end piece of the cable is of in particular conically tapering design, in that the first cutout has a second section for a stripped portion of the cable end piece, wherein the contact structure adjoins the second section, in that the second cutout is formed spatially offset in relation to the first cutout and by way of its end adjoins the second section of the first cutout in order to allow optical monitoring of the formation of the connection between the litz wire and the contact structure; and in that the third cutout is formed spatially offset in relation to the first cutout and in relation to the second cutout and by way of its end adjoins the second section of the first cutout, wherein the third cutout is designed for receiving and passing solder to the second section of the first cutout in order to form the connection between the litz wire and the contact structure there. - an electrically insulating body having a first cutout, a second cutout and a third cutout; and - an electrically conductive contact structure, which is coupled to the body, wherein the contact structure ∘ is in part embedded into the body in order to be connected to a litz wire of the cable in the interior of the body, and ∘ in part exits from the body in order to be connected to a connection of the printed circuit board; ∘ is in part embedded into the body in order to be connected to a litz wire of the cable in the interior of the body, and ∘ in part exits from the body in order to be connected to a connection of the printed circuit board; wherein the first cutout for receiving an end piece of the cable has a first section for a non-stripped portion of the cable end piece, wherein the stripped portion of the cable end piece comprises the litz wire, characterized in that the first cutout for receiving the end piece of the cable is of in particular conically tapering design, in that the first cutout has a second section for a stripped portion of the cable end piece, wherein the contact structure adjoins the second section, in that the second cutout is formed spatially offset in relation to the first cutout and by way of its end adjoins the second section of the first cutout in order to allow optical monitoring of the formation of the connection between the litz wire and the contact structure; and in that the third cutout is formed spatially offset in relation to the first cutout and in relation to the second cutout and by way of its end adjoins the second section of the first cutout, wherein the third cutout is designed for receiving and passing solder to the second section of the first cutout in order to form the connection between the litz wire and the contact structure there.
