Huging processing is one of the terminal processing methods for winding, and it is a widely adopted process that utilizes the principle of resistance welding to fix (and conduct) the lead wires at the start and end of the winding to the terminal that becomes the bobbin terminal. The most representative form of single-wire hugging involves sandwiching the terminal lead wire in the U-shaped groove of a U-bent terminal, applying pressure from both sides of the U with two electrodes (fixed and movable), and passing current to heat the lower part of the U, melting the insulation of the lead wire (peeling and conducting) while simultaneously completing the fixation of the lead wire. The processing conditions for the hugging process include terminal pre-bending conditions (pressure, bending dimensions, etc.), current values during hugging (peak value, effective value), energization time, electrode pressure, and electrode sinking amount. The evaluation of the finished product includes assessing the appearance of the hug (spatter, melting state (absence of sparks, etc.)), peeling state (insulation peeling rate), cross-sectional reduction rate (longitudinal and transverse cut sections), and wire strength (tensile strength of the wire material, primarily based on material breakage). Consulting services will cover guidance and support regarding the basic design of the hugging process, condition setting, and management methods.
