Image of Smiths Interconnect HBB Connector

Ruggedized High Performance Circular Power Connectors for Harsh Environments.

The newly re-launched HBB series of single pole high power 300A and 500A circular connectors from Smiths Interconnect offer a compact, lightweight and ruggedized heavy duty connector designed for use in all types of harsh environment applications, including electric motor drives, military ground vehicle turret systems, rail transport and industrial applications. Now assembled by Aerco, they are available with low MOQs and short lead-times.

Available in a RoHs compliant Black Zinc Nickel finish, the HBB delivers a more efficient, higher current transmission in a more compact and lighter connector and with a superior endurance of 5000 mating cycles. Design SWaP goals of delivering high power within a small size and minimal weight interconnect solution are realised with 300A delivery implemented in a size 17 shell and 500A delivery in a size 21 shell. The robust aluminium shell is available in three different shell polarizations, fully sealed to IP67 ingress protection and featuring 360° EMI/RFI shielding via a customer serviceable conductive ‘O’ ring, which is fitted as standard to receptacles.

The HBB series is rated for surge/inrush currents of 6 kA for the 300A and 10kA for the 500A for 1 sec, making it suitable for deployment in applications like induction motors and power converters.

The tactile ‘push mate’ mating provides confirmation of a full mate preventing “attached not locked” condition. The design facilitates the easy mating and un-mating with simple push to lock and 1/8 turn to unmate while in close proximity to neighbouring devices, supporting applications where higher density packing is required in space constrained environments. Safety protection includes a safety interlock last make, first break with finger protection on pin and socket contacts.

Compliant to the MIL-DTL-5015 specification for heavy-duty circular electrical connectors for harsh environments, the connectors feature the best electrical performance and high levels of shock and vibration immunity due to the use of Smiths Interconnect’s hyperboloid contact technology. The ultra-low resistance and smooth and light wiping action of the hyperboloid contacts results in low fretting fatigue/corrosion and long contact life with minimal degradation in performance. The hyperboloid contact design ensures this high degree of immunity to shock and vibration, guaranteeing electrical continuity in all circumstances. Contact resistance figures as low as 0.03mΩ keeps resistive losses and generated heat at a minimal, facilitating maximum transmission performance

The plugs and receptacles are gender reversible, being available with either pin or socket contacts and they can be ordered with optional straight or right angle back shells. Accessories include crimp lugs, heat shrink boots and additional O-rings

Standard operational temperature range is -55°C to +150°C, voltage rating at sea level is 750vdc, and dielectric withstand voltage at sea level is 2250vdc.

High power, modular connectors for all on-board power applications within the rail market.

The Transformer Series HeavyPower (TSH) connectors from Smiths Interconnect are a range of ruggedized, high reliability, high power, heavy duty interconnects which offer a modular solution for all on board power applications within the harsh environment rail market.

The TSH are available in 1 to 4 pole versions and employ Smiths Interconnect’s latest evolution of their Hypertac® hyperboloid technology: the Tortac® contact. The contact’s single piece hyperboloid construct supports higher current ratings than bifurcated designs and features very low fretting corrosion, allowing TSH to support currents of 300A per pole with an endurance of over 500 mating cycles. Connector styles include straight and right-angle versions and a ‘Y’ branch variant supporting additional use as a power junction box.

Comprising a polyamide insulator with a passivated aluminium frame, the design conforms to rail fire and smoke standards EN 45545-2, NF F 16-101 and NFF16-102 and has an environmental ingress protection rating of IP66/IP67 when mated. The design of the insulator ensures that correct voltage creepage distance clearances are met, providing high electrical protection in severe environments. It is fully compliant to EN50124 Pollution Degree 4, allowing external deployment of TSH on train roofs, under car on bogies and between vehicles as inter-carriage jumpers, without the need for cleaning

To support inter-coach jumper applications, an integrated anti-swaying device on the connector backend mitigates potential cable degradation and obviates the need for additional cable support clamping. An optional ‘Y’ branch connector style, TSHY, is available which splits each pole input into two outputs, replacing the need for junction boxes and so saving space and weight and simplifying maintenance. Typical design use would be a three pole ‘Y’ connector taking in the train’s three phase power and then branching each input phase into two output feeds, with each output supplying separate motors on the bogies.

The modular range employs a unique do-it-yourself system, offering a configurable architecture which enables customers to design their own platform solutions with just a few elementary piece parts. This allows many connector configurations to be supported by holding a minimal amount of piece part stock, reducing supply chain, cabling and maintenance costs and facilitating quick and flexible time to market. No special tools are needed except crimping tools, resulting in a further reduction in stock and kitting/logistic management.

TSH connectors have a voltage rating of 3600V, and a standard temperature range rating of -55°C to +125°C.

Reliable Harsh Environment Interconnect Solution, Optimised for Rail and Embedded Applications.

The REP series from Smiths Interconnect is a panel or cable mounted multi-pole, sealed, light weight, polycarbonate plastic connector, which delivers optimal durability in harsh environments. The connectors provide a cost effective, quick and secure connection for embedded equipment such as sensors, brakes, lighting, air conditioning and communications.

Plugs and receptacles with crimp terminated contacts are available for cable to cable solutions, with the receptacle also supporting panel mounting. Receptacle versions are also available loaded with straight or bent contacts with solder terminations for PCB or panel mounting. Both versions are available in 2, 6 and 12 way layouts, all with polarized guides, and providing over 500 mating cycles. Connection is fast, simple and secure with push to mate and press and release to un-mate.

A shunt accessory is available for the 6 and 12 way receptacles, enabling electrical derivation inside the connector for transmission of information to different locations. Other accessories available include cable retainers, panel seals, panel mounting brackets, plastic dummy contacts and filler plugs.

The connector employs Smiths Interconnect’s proven Hypertac® hyperboloid contact technology which, with its superior performance, ensures excellent reliability even under high levels of shock and vibration. Contact features include a 360 wiping action, low insertion/extraction forces, minimal contact resistance, immunity to fretting corrosion and a long life cycle in harsh environments. The hyperboloid contact supports a 30% higher current carrying capacity than standard contacts of the same size, with a rating of 18A.

The REP series is qualified to stringent European rail safety standards, conforming to the fire and smoke requirements of NFF 16-101, NFF 16-102, EN 45545-2 and UL94V0 standards and shock resistant levels to EN 61-373. Environmental protection ratings of IP66 and IP67 are achieved through the integration of over-moulded silicone grommets and interfacial seals.

The single sized crimp contact caters for cables from 0.50mm² to 2.5mm² (24-12AWG), offering a significant cost of ownership saving in terms of reduction in inventory holding and maintenance costs. Further, no special tools are required for assembly with the consequent reduction of supply chain, maintenance and cabling costs.

Voltage rating is 230V, with a standard temperature range rating of -55°C to +110°C (panel mount version up to +250°C).
