Hypertac has extended its HBB family of connectors to include two- and three-pole 300A inserts with built -in safety loop pins integrated into a single quick-release connector shell. The company says that the product development and extension of the HBB range, including IP2X protection, is aligned to customers' requirements and industry trends to integrate even more power in less space.
In general, the HBB connector line combines high current handling capability with small size and exceptional environmental performance for demanding power applications. The connector range is suitable for use in all types of high power applications, and particularly applicable to electric drives and servos used in fighting vehicles, power generation (DC and/or AC), ground-based and airborne avionics systems, civil aerospace, rail transportation, automotive and medical sectors.
According to Hypertac, by utilizing just one connector shell, latching mechanism and backshell, the new product offers improved connector packaging compared with the use of two or three individual single-pole connectors so designers do not have to include the extra space, which is needed for mating and unmating multiple single-pole connectors. The HBB 2/3 pole connector includes two 300A rated contacts integrated into one connector shell measuring just 60mm in diameter and three 300A rated contacts integrated into one connector shell measuring just 72mm in diameter, providing up to a 40% smaller connector footprint and reducing weight and cost.
Further, safety regulatory requirements have led Hypertac to introduce two important safety protection features. The first is 'last mate first break' loop pins which enable customers to design their equipment to automatically turn power on and off when connectors are mated or unmated. The second is full IP2X protection on the pin and socket in either gender. IP2X is an important safety feature in power connectors due to high current and high voltage systems operating up to 1,000V.
The 2/3 pole connectors are available in robust aluminium metal shells which are fully sealed to IP67 and feature 360 degree EMI/RFI shielding. IP67 sealing on power management equipment in aerospace, fighting vehicles and industrial applications is becoming essential due to protecting the high voltage and high current power electronics from water and /or fluid ingress.
Configurations are available in cable or panel mount, straight or 'multi-angle' right-angle back shells which allow users to simplify their cable management architecture, further increasing reliability and reducing the likelihood of interconnection failures.
Designed for easy mating and quick release, the HBB 2/3 pole connectors use Hypertac's hyperboloid contact technology which offers high reliability and high integrity. The contact system provides a current rating of 300A from a 9mm diameter pin. Additional benefits include contact resistance figures as low as 0.05mohm which helps to reduce resistive losses. This also assists with thermal management which allows better power handling in a smaller space with a lower overall mass.
The HBB series features a polarized design with a variety of options that support assembly, allowing simple maintenance and speedy changeover for minimal system downtime. Rated for use up to 1000VDC, the HBB series can accept cable sizes up to 70mm2 for 300A versions. Metal receptacles and plug shells can be specified with a variety of plating options including zinc/cobalt, cadmium and electroless nickel, says the company.
