BRADENTON, Fla.—ETCO Incorporated has introduced a full line of locking ring electrical terminals that prevent twisting and rotation during the manufacture and shipping of HVAC equipment, the company said in a release.
ETCO Locking Ring Terminals feature four teeth that extend 0.023 inch from their surface. Each tooth has a 40-degree angle that provides sharp wedges that bite into painted or plain metal surfaces to stay in place. Maintaining connection integrity during the manufacture and shipping of HVAC equipment, they are reported to prevent rotation, arcing, and electrical shorts.
Constituting 92 percent of the thickness of the ring, the teeth on ETCO Locking Ring Terminals penetrate into plain or painted metal surfaces to withstand vibration and prevent twisting and rotation, which can cause short circuits. The locking ring terminals attach to 12-22 gauge wire using an F-crimp for a more secure connection than conventional flag ears, according to the manufacturer.
“Our product innovation—locking ring terminals—is engineered to maintain connection integrity, even under vibration and harsh conditions,” said ETCO Vice President Sean Dunn, in an emailed statement to Design-2-Part. “These U.S.-manufactured terminals are designed for 12–22 AWG wire and feature a unique locking tooth design that helps prevent arcing, rotation, and short-circuit risks during equipment manufacturing and transit.”
ETCO Locking Ring Terminals are priced according to size and quantity and are manufactured in the USA to eliminate supply chain issues. Evaluation samples are available upon request, the company said.
