This isn't a wire crimp or a board header; it's a power interconnect that clamps onto a busbar, typically in high-current distribution assemblies inside power supplies, UPS systems, or industrial cabinets. The black housing and box packaging are identifiers, but the key functional spec is the terminal type: busbar clip, which tells you the connection method and the kind of mating busbar it's built for. ## Termination and Mounting — Solder, Not Crimp Termination is solder, meaning the wire or PCB pad is soldered into the clip's tail. This is a permanent, high-reliability joint — no crimp tool, no field re-pinning with a basic kit. If you're maintaining an existing harness and the clip has failed, you'll need a soldering iron on site, not a crimper. The solder joint gives a stable, low-resistance connection for sustained current, but it also means the clip is one-and-done: desoldering it for reuse risks damage to the busbar interface.","metaTitle":"TE 1643903-1 Crown Clip Busbar Clip, Solder Termination","metaDescription":"TE Connectivity 1643903-1 Crown Clip busbar clip, solder termination, black.
