Smiths Interconnect Transformer Connector

By News Release | January 19, 2015

Smiths Connectors’ Transformer Connector allows engineers to tailor interconnect solutions to the demands of individual applications.

Smiths ConnectorsSmiths Connectors Transformer Connector launched its new Transformer Connector Range, an innovative family of high-density modular connectors that provides customers with an enhanced ability to tailor interconnect solutions to the demands and requirements of their individual application environments.

One key market that the new products address is rail applications, where extreme pressure is placed on connector technology manufacturers to fulfill critical rail-specific performance challenges of reliability, safety, maintenance, and modularity in addition to standard compliance, as well as meet stringent electrical and environmental requirements.

Smiths Connectors has responded to these specific challenges with the Transformer Connector Range, a comprehensive series of high-density, modular connectors for all on-board power applications within the rail market.

The creative design of the Transformer range includes a number of innovative features:

  • Multiple configurations using the same piece parts
  • Cost savings in working capital with local customer assembly
  • Flexibility to integrate local content for components and cabling

Smiths Connectors’ Transformer modularity enables customers to design their own solutions by supplying the elementary components of the whole connector. It employs a unique do-it-yourself system based on the building block principle. It has been customized for applications requiring the transmission of very high currents such as power distribution, inter-coaches, and bogies while guaranteeing the highest level of safety for the passenger.

The connectors also use the Smiths Connectors’ HPC (High Power Contact) technology, a spring-shaped contact made of aluminum or copper that allows for more contact points to reduce overheating and to achieve low mating force during the connection. This contact technology design meets the trend to increase energy levels on electrical and electronic equipment for managing higher current ratings.

The Transformer range is available in two-, three-, or five-pole versions and supports up to 700A per pole and a voltage rating of 3600V. The connectors are easy to assemble and use due to the incorporation of just three contacts, and cross-section cables can be covered from 25mm² to 350mm². No specific tool is required, with consequent reduction of supply chain, maintenance, and cabling costs.

Made with a plastic insulator and aluminum frame, the Transformer optimizes against ballast and enables weight savings that contributes to reduced energy consumption. The materials used ensure compliance with fire and smoke standards, according to NF F 16-101 & NF F 16-102 and EN 45545.

“Through interconnect innovation Smiths Connectors has designed a rugged, reliable, and high-performance modular solution for rail transportation applications, as well as hybrid and electric vehicles and various other industries,” said Gabriel Guglielmi, Smiths Connectors’ vice president of business development and strategy.
