Single tine IDC contacts reduce costs by 25%
AVX has introduced a single contact version of its 9176 series of Insulation Displacement Connectors (IDCs), which are widely recognised for providing highly reliable, gas-tight wire-to-board connections in a range of harsh environment applications.
Backward compatible with existing 9176 series connectors with regard to contact and footprint, the 9176-65X single tine IDC contacts exhibit the same robust, reliable performance the series is known for while reducing cost by 25%, width by 50% (2.5mm vs. 5.0mm), and height by 10% (5.05mm vs. 5.6mm), the latter of which is especially valuable for SSL applications, as it helps prevent shadowing.
Designed to satisfy the demanding cost versus performance objectives for customers in the SSL, smart grid, smart meter, machine control, commercial building control, industrial control, medical and transportation markets, the 9176-65X contacts also feature a multipurpose cap that keeps the contacts in position prior to automatic placement and then acts as an assembly tool for terminating wires, effectively removing the costs associated with hand soldering, crimping and two-piece connectors.
Rated for 600VAC, 5–9A, and operating temperatures spanning -40 to +125°C, the 9176-65X contacts accept 24–18AWG wires, are available in two configurations for maximum flexibility (stopped end cap and through wire cap), and can be potted or overmolded for waterproof performance. Tested to automotive levels of shock, vibration and temperature cycling, the series is also RoHS-compliant and certified to both UL and CAN/CSA C22.2. Available for immediate product integration, the series is tape and reel packaged for single contact automated placement and SMT reflow.
“When we initially developed the 9176 series, the market demanded a current rating up to 10A, so we used dual IDC tines. Current market demands are largely in the 3–5A range, though, and we’re always up against market price pressure, so we developed the single tine 9176 IDC to satisfy lower current ratings and reduce costs,” said Tom Anderson, Product Manager, AVX. “Consequently, we were surprised when product testing for the 9176-65X series demonstrated that they can achieve up to 9A with an 18AWG wire. Normally, above-ambient temperatures limit current levels; so, the fact that we can achieve a 9A rating with a single tine is a real testimony to the high quality design of our IDCs, which yield less than 3mΩ of contact resistance, effectively mitigating heat build-up.”
