1. A soldering aid for connecting a cable to a printed circuit board, the soldering aid comprising:
an electrically insulating body having a first recess, a second recess, and a third recess; and
an electrically conductive contact structure captively connected to material within the body, the contact structure being partially embedded in the body so as to be connected to a cable core of the cable inside the body and partially protruding from the body so as to be connected to a terminal of the printed circuit board,
wherein:
the first recess is conically tapered to receive an end portion of the cable and has a first section for a non-stripped portion of the cable end portion and a second section for a stripped portion of the cable end portion, the stripped portion of the cable end portion including the cable core, and the contact structure adjoining the second section;
the second recess is spatially offset from the first recess, an end of the second recess adjoining the second section of the first recess so as to enable optical verification of formation of a connection between the cable core and the contact structure; and
the third recess is spatially offset from the first recess and from the second recess, an end of the third recess adjoining the second section of the first recess, the third recess being configured to receive solder and transfer the solder to the second section of the first recess so as to form the connection between the cable core and the contact structure at the second section of the first recess.
