AVX extends BTB pin jumper series for tolerance absorption

Fountain Inn, SC. AVX has extended its new series of pin jumpers for board-to-board (BTB) and module-to-module connections in solid-state lighting (SSL) and other low-pin-count industrial applications with a new two-position pin jumper. When used in conjunction with the new 2.5-mm 70-9296 Series STRIPT horizontal, poke-home contact without a wire stop—which, the company reports, is both the first industrial poke-home connector available without an integral wire stop and, currently, the only industrial poke-home connector with a 2.5-mm profile—the new 1- and 2-position 10-9296 Series BTB pin jumpers are allowed to pass straight through the contacts, completely unrestricted, until the final, user-defined mating dimension is achieved. Unlike traditional BTB pin jumpers—which are made to mate with traditional connectors and are thus closed on the back end, limiting the depth to which a pin can travel and restricting the amount of BTB or module-to-module mating tolerance that the jumper can absorb—the new 10-9296 Series BTB pin jumper/709296001025016 contact combination absorbs the maximum amount of component and assembly tolerances during the mating process, effectively eliminating the PCB and housing tolerance stack-up issues common to traditional connector systems in linear and coplanar applications.

The new 10-9296 Series BTB pin jumpers are rated for 9 A, 300 VAC based on contact spacing, 3-cycle durability, and operating temperatures spanning -40°C to +105°C, and are currently available in 1- and 2-position versions in two different pin lengths. The 26-mm pins are designed to support linear BTB connections, while the currently unique-to-market 38.15-mm pins are designed to support linear module-to-module connections in which the contacts are embedded within plastic housings. All four variants have a standard 1-mm diameter pin that is mating-compatible with competitors’ traditional 4-mm-pitch poke-home connectors, as well as the company’s own 70-9296 Series 2.5-mm STRIPT contacts—but offer two clear advantages: a shortened insulator (just 5.1 mm) and a unique insulator geometry with dual-chamfered ends that provide a watertight connection when seated within a corresponding housing cavity.

“We tooled our 1-position 10-9296 Series pin jumper for a customer and then released it to market in April to provide engineers working on SSL and other low-pin-count industrial applications with user-friendly solutions for achieving variable final mating positions for maximum tolerance absorption, especially when combined with our new no-wire-stop 2.5-mm 70-9296 Series STRIPT poke-home contacts,” said Tom Anderson, connector product manager at AVX. “We tooled the new 2-position 10-9296 Series pin jumper as a standalone product to help resolve customer frustrations regarding the unstable delivery schedule of similar products from competitors. However, AVX didn’t just duplicate the current products on the market. We re-engineered our product to make it cleaner than competitors’ offerings, which are often built as a larger version and then broken or cut to length, leaving burrs or vestiges behind. All of the customers who have sampled our new two-position BTB pin jumper have commented on the sleekness and cleanliness of our product.”

The new 10-9296 Series BTB pin jumpers have a glass-filled Nylon PA-66 insulator approved to UL94 V-0 and lead-free, tin-over-nickel-plated brass contacts.
