Pin jumpers’ insulator geometry assure watertight connections
Designed for use in conjunction with AVX’s 2.5mm no-wire-stop 70-9296 series Stript poke-home contact, the 10-9296 series board to board pin jumpers are also drop-in compatible with competitors’ jumpers. They offer a shortened insulator, approximately 38mm pin length, that achieves watertight connections, claims AVX.
The 10-9296 series pin jumpers can be used in board to board and module-to-module connections in solid-state lighting (SSL) and other low-pin-count industrial applications.
When used in conjunction with the 2.5mm 70-9296 series Stript horizontal, poke-home contact without a wire stop, currently the first industrial poke-home connector available without an integral wire stop and the only one with a 2.5mm profile, the pin jumpers are allowed to pass straight through the contacts. They are unrestricted, until the final, user-defined mating dimension is achieved. Unlike traditional board to board pin jumpers which are made to mate with traditional connectors and are thus closed on the back end, limiting the depth of pin travel and restricting the mating tolerance that the jumper can absorb, the 10-9296 series’ contact combination absorbs the maximum amount of component and assembly tolerances during the mating process. According to AVX, this effectively eliminates the PCB and housing tolerance stack-up issues common to traditional connector systems in linear and coplanar applications.
The 10-9296 series board to board pin jumpers are rated for 9A, 300V AC based on contact spacing, three-cycle durability, and operating temperatures spanning -40 to +105 degree C. They are available in two pin lengths of 26mm to support linear board to board connections and 38.15mm to support linear module to module connections in which the contacts are embedded within plastic housings. Both variants have a standard 1.0mm diameter pin that is mating-compatible with competitors’ traditional 4.0mm-pitch poke-home connectors, as well as the AVX 70-9296 series 2.5mm Stript contacts. AVX says that there are two clear advantages: a shortened insulator (just 5.1mm) and an insulator geometry with dual-chamfered ends that provide a watertight connection when seated within a corresponding housing cavity.
The 10-9296 series board to board pin jumpers have a glass-filled Nylon PA-66 insulator approved to UL94 V-0 and lead-free, tin-over-nickel-plated brass contacts. UL approval is in progress, and is expected in April 2018. AVX is also currently sampling a two-position version of the board to board pin jumpers, and expects to announce production inventory by May 2018.
