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.
