USB-C Receptacle with Screw-Down Retention
The Molex 2057141001 is a USB Type-C receptacle from the 205714 series, carrying the full 24-contact complement of the USB-C interface. It's a shielded, right-angle surface-mount part with additional through-hole anchor points — the mounting flange and through-hole tails take the mechanical load off the SMT pads when the cable is yanked or the connector sees repeated mating cycles. Rated for USB 3.2 Gen 1 (5 Gbps Superspeed), it handles the full signal set plus power delivery at 30VAC/DC across three current tiers: 0.25A on the sideband pins, 1.25A on the configuration channel, and 5A on the VBUS and GND circuits. The gold contact finish and 10000-cycle rating mean this receptacle is built for field-service equipment and test fixtures that get plugged and unplugged daily, not a consumer phone port that sees a few hundred cycles.
Mounting and Mechanical Anchoring
This receptacle uses a hybrid mounting scheme: the signal contacts are SMT on the right-angle footprint, while the through-hole posts and mounting flange provide the mechanical backbone. The flange accepts a screw for panel or bracket attachment — the 'screw hole' in the description — which prevents the connector from levering off the board when the cable is under strain. The steel and stainless shell adds another layer of rigidity, and the UL94 V-0 rated housing keeps the assembly compliant inside enclosed equipment where flame spread is a concern.
Signal Integrity and Shielding
The steel/stainless shell provides a continuous ground reference around the contact array.
Current Rating Breakdown
The three-tier current rating — 0.25A, 1.25A, and 5A — maps to the USB-C pin assignment. The 5A path is on the VBUS and GND pins that carry power; the 1.25A rating covers the CC (configuration channel) pins used for cable orientation and power negotiation; the 0.25A rating applies to the sideband use (SBU) pins.
