Solderless connectors simplify multiple wire terminations using poke-in tech

Date: 05/08/2014
TE Connectivity releasable poke-in wire solderless connectors which simplify multiple wire terminations using poke-in technology. The wires can be replaced without complex disassembly or damage to the release mechanism during activation.

“The SMT releasable poke-in connectors’ release mechanism is integral to the terminal and recessed below the top side of the connector to prevent inadvertent activation or breakage during wire insertion,” said Alex Hunt III, product manager, TE Intelligent Buildings. “Activating the release mechanism is easily accomplished with a ball point pen or small screwdriver tip.”

These new connectors are available in 1, 2 and 3 positions and accept 18, 20 and 22 AWG solid and stranded wires. The low-profile design has a flat top surface that allows for SMT vacuum pick-up. Rounded corners minimize light obstruction and resultant shadowing. The connectors are available in tape and reel packaging for high-speed SMT and thru-hole processing.

The connectors operate at temperatures between -40°C and 130°C, have current ratings of 9A on 18 AWG wire (5A on 20 – 22 AWG wires), and can withstand voltages up to 600VAC/DC. The connectors feature RoHS compliant and UL 94 V0 rated high temperature resistant thermoplastic material. The contacts are constructed using a high conductivity copper alloy with tin over nickel plating. The connectors have redundant SMT pads that prevent peeling and are side-by-side stackable with pads on 4mm centers.

The SMT releasable poke-in connectors are best used in LED lighting controls, general illumination LED modules for fixtures, interconnecting strings of printed circuit board based LED light modules, and various non-lighting applications that require connecting wire leads to printed circuit boards.
