The press-fit termination means no solder joint in the current path, which keeps connection resistance low and makes the part rework-friendly in a backplane or panel assembly. A molded polyamide (nylon) housing carries the tin-plated copper alloy contacts, and the included cover protects the screw terminals from accidental shorting or debris ingress. The 6-32 steel screws accept ring terminals or bus bars, making this a direct wire-to-board interface for power cabling. The through-hole mounting anchors the part against the shear force of heavy-gauge wire termination. ## Press-Fit Termination for Solderless Assembly Press-fit pins eliminate the thermal cycle of wave or reflow soldering, which matters when the connector lands on a thick multilayer board with heavy copper planes. The compliant pin geometry compresses into the plated through-hole and holds by interference fit — no solder fillet to inspect, no void risk. This termination style is standard in telecom and server backplanes where rework access and high-reliability interconnects are the norm. The through-hole mounting type provides mechanical retention during the press operation and resists the extraction force when a power cable is disconnected. Board layout should account for the plated hole diameter and the keep-out zone around the press-fit zone — the datasheet drawing gives the exact footprint.","metaTitle":"TE Connectivity 5055557-4, 10-Pin Screw Terminal Power Tap","metaDescription":"TE Connectivity 5055557-4 screw terminal power tap, 10 pins, 25 A rating, press-fit termination, includes cover.
