Smiths Interconnect HBB Circular Connector Series is Rising to the Challenge of High Power Defense applications
As the defense and aerospace industries increasingly use hybrid and electric engines for ground vehicles and aircraft, they are demanding three-phase power or redundancy lines to serve as a reliable backup facility. To rise to this challenge, Smiths Interconnect has launched its 5-pole HBB series, featuring all the benefit ts of the hyperboloid contacts and the quick-latch mechanism. Gregory Kay, global product line manager at Smiths Interconnect explains why this new range was developed and what it means for the defense industry.
The 5-pole is an expansion of the existing HBB platform. The new configuration consists of the existing size 21 shell but contains five poles, each with size eight contacts as well as two interlock pins.
This means that in a very tight space, the customer can run five power lines which increases the connectors’ flexibility and offers the ability to run redundant lines as required.
When compared to traditional 38999 screw-thread connectors, the HBB series offers several additional benefits.
One of the primary value-added benefits of the HBB series is that its contacts feature the Hypertac Hyperboloid technology. These Hyperboloid contacts have low insertion and extraction forces and are easy to mate and unmated. In addition the Hyperboloid contact provides very low contact resistance, minimizing temperature rise with power. By combining the HBB’s unique shell design with the Hyperboloid contact, Smiths Interconnect can provide excellent vibration and shock immunity in this exceptionally rugged series.
An added benefi t of the new 5-pole version is that it has even higher safety protection than the single pole. These connectors also feature interlock pins, which are last-mate first-break, so the last thing that connects during mating is the first thing that breaks when it gets disconnected.
By utilising this interlock feature, customers can ensure the utmost safety for their operators.
A quick-latch mechanism is comprised of the whole HBB series with a spring-loaded collar, which can be unmated through a light turn. When the connector is mated, the locking ring moves and latches itself, providing haptic and visual feedback to confirm that it is latched. Compared to a 38999, the likelihood of not fully mating the connector is drastically reduced. This system makes it physically easier to latch the connector by the operator, making it possible to place them much closer together on a panel.
As the five-pole can handle five different lines, it is ideal for combat vehicles both ground and air as it can carry power to various areas on the vehicle. Looking forward, connectors with these capabilities will be increasingly in demand.
We’re starting to see more hybrid fighting vehicles, and soon we will see all-electric. These connectors will be needed for all the ancillary equipment as well as the drive train itself.
The HBB five-pole is also ideal in wider applications within defence, such as missile launcher platforms and ground radar installations, where the requirements for robust high-power interconnectivity are ever-growing.
Smiths Interconnect launches high-power connectors for demanding defense applications
HBB circular connector series now available in the five-pole version
Smiths Interconnect, a leading provider of technically differentiated electronic components, subsystems, microwave, optical, and radio frequency products announced today the launch of its HBB five-pole connector in addition to the already existing single-pole version. The new five-pole is an expansion of the existing HBB platform. The new configuration consists of the existing size 21 shell but contains five poles, each with size eight contacts as well as two interlock pins. This means that in a very tight space, the customer can run five power lines which increases the connectors’ flexibility and offers the ability to run redundant lines as required.
