The TE Connectivity 1551953-1 is a Crown Clip Junior busbar clip — a solder-terminated interconnect component designed to attach a busbar to a PCB. Unlike a crimp terminal or screw lug, this clip accepts the busbar edge and is soldered directly to the board, creating a low-resistance power path.
Termination and Mounting — Solder-to-Board Busbar Clip
Termination is solder — the clip is placed on the PCB and reflowed or hand-soldered, with the busbar sliding into the clip after assembly. This is a board-level power interconnect, not a field-wireable terminal. The solder joint carries the full busbar current; the clip body provides mechanical retention and electrical contact to the busbar edge. No wire gauge applies — the conductor is the busbar itself.
