HBB connector series: when high-power fits in a small, light and reliable interconnect solution

Given the incredibly harsh environments that connectors can be subjected to, from defence vehicles to railway lines, aircraft and even outer space, you might wonder how these products are able to withstand such challenging applications. Smiths Interconnect’s answer is in the design of technologically advanced, high quality solutions that are required for a high degree of safety and durability

The HBB Series is a high-power, high reliability family of connectors that incorporate hyperboloid contacts and are able to withstand extremely harsh environments. However, what makes the HBB Series particularly unique is the versatility of the product and the range of applications and markets that it can be used in.

HBB Series

Because HBB connectors combine a high current handling capability with their small size, they can be used in all types of high-power applications, including use in electric vehicle drive systems, rail transport, defence and industrial applications. The HBB Series is rated for surge currents of 6 kA for 1 second in the 300 amp and 10kA for 1 second in the 500 amp connectors, which also makes them suitable for use in induction motors and power converters.

Additionally, HBB connectors have a robust RoHS design (restriction of harsh substances). The RoHS directive is aimed at restricting the use of certain dangerous substances commonly found in electronic equipment like Lead (Pb), Mercury (Hg), Hexavalent chromium (Hex-Cr), and Polybrominated diphenyl ethers (PBDE), with the ultimate goal of reducing damage to the natural environment at the end of the product’s life-cycle.

Ultimately, however, one of the strongest competitive advantage of HBB connectors is their user-friendly push-lock mating and quick-release latch unmating mechanisms which allow the connectors to be connected and disconnected with ease. This, matched with its hyperboloid contact design for power density and high shock and vibration resistance, makes the connector a popular choice among customers.

HBB connectors are fulfilling a growing demand in the industrial market for high reliability products, a demand which is expected to continue growing for years to come and are actually mainly used in applications like power converters and distribution in heavy duty vehicles, where the combination of high power, small footprint, quick release and long life is key for the performance of the devices.

Further configurations with additional poles so with improved power performance can be offered to the market to meet the increasing demand of power handling capability.
