AVX card edge connector targets Edison-replacement LED Bulbs

AVX has unveiled a high-performance, bottom entry, board-to-board, card edge connector system for Edison-replacement LED bulb assemblies.

“AVX developed its new 9159 Series bottom entry, card edge connector in response to the steady growth of the LED replacement bulb market and, in particular, the popularity of Edison-replacement LED bulbs,” says Tom Anderson, product manager at AVX.

“Edison-replacement bulbs pose several electronic design challenges with regards to space, cost, and reliability, but this latest addition to the 9159 connector series satisfies all of these application challenges by providing both high performance and high reliability in a compact, cost-effective design,” he adds.

Said to provide significant cost and process improvements over existing products and termination methods, the 9159-500 surface mount connector allows a perpendicular PCB to be mated to a top-mounted main FR4 or metal core PCB from the bottom side using standard pick and place equipment and reflow soldering.

Consequently, the new 9159 Series card edge connector provides a single-piece volume production solution that eliminates the labor-intensive process of hand soldering wires to the top side of the PCB in LED replacement bulbs.

The connector is available in a range of 2-6 positions, which allows for increased functionality in application designs, such as colour control or specific line control.

For example, white bulbs only require two connections, while architectural bulbs require two connections for power and ground in addition to four control lines to support red, green, blue, and white coloring.

Featuring dual PCB slot widths, the bottom entry, card edge connector is also compatible with both 0.8mm and 1.6mm PCBs, which provides design engineers with increased flexibility regarding PCB layout and selection.

The connector is also available with or without a safety cap, which can be supplied either preassembled or separately, and features an extremely low-profile through-board height (1.00mm with the cap and 0.6mm without) to avoid interfering with light output.

Rated for 10 mating cycles, 2A per contact, 250VAC/DC, and use in temperatures ranging from -40°C to +120°C, the 2mm pitch connector provides high performance in a compact design, as well as facilitates fast assembly and board removal.

Featuring gold-plated beryllium-copper (BeCu) spring contacts, the connector also provides long-term reliability, substantial insertion force tolerance, and maximum mating travel to absorb common manufacturing tolerances.

Fully insulated with halogen-free material, AVX’s 9159-500 bottom entry, card edge connector features UL1977 approval, as well as meets the UL94 V-0 flammability standard.

Although targeted at the LED bulb and spotlight markets, AVX’s new 9159-500 single-piece, surface mount, bottom entry, card edge connector can also be used for rear connections on strip PCBs in addition to several other application that require rear plug-ins.
