Hirose Connectors Get International Innovation Recognition
B

oth the FX26 Series and BM46 Series board-to-board connectors by Hirose Electric Co., Ltd. have been selected as Innovation Award Honorees for CES 2020, the Consumer Electronics Show held annually in Las Vegas, Nevada in the United States.

Selected in the “Vehicle Intelligence & Transportation” category is the FX26 floating board-to-board connector with high heat resistance up to 140°C that withstands severe vibration environments and was developed for internal connection of powertrains including motor controllers, the key product in electric vehicles (EV) and hybrid electric vehicles (HEV). Additionally BM46, a multi-RF board-to-board connector developed for next-generation high-speed communications, such as WiGig and 5G, has been chosen in the “Mobile Devices and Accessories” category.

CES, hosted by the Consumer Technology Association (CTA), is the largest consumer electronics trade fair, held annually in Las Vegas, Nevada in the United States every January.

The CES Innovation Awards internationally recognize multiple noteworthy products in 28 product fields based on the following criteria: product quality, design aesthetic, value provided to users, uniqueness and newness of product specifications, and innovation over competing products.

FX26 Series
The FX26 Series was developed for the internal connection of powertrains including motor controllers, a vital component in EV and HEVs.

It is a floating board-to-board connector with high heat resistance up to 140°C capable of withstanding high vibration environment. Conventional wire-to-board connectors have been widely used in the internal connection of driveline devices. However, as the number of units produced has increased dramatically, it has become difficult for such connectors to satisfy customer requirements in terms of ease of assembly and cost. Additionally, board-to-board connectors have not been widely used due to problems with heat, vibration, and space restraints.

The FX26 Series overcomes these issues and delivers reliable quality for powertrain connection, all while improving assembly times and reducing costs by replacing traditional cable connectors. FX26’s narrow 1mm pitch between terminals adds value to applications by enabling size reduction.

BM46 Series
The BM46 Series is a multi-RF board-to-board connector developed for 5G wearables, portables, and mobile devices. Multi-RF capability enables digital signal and multi-RF signals to be housed in the same connector, enabling smaller devices and increased productivity.

BM46 has excellent high frequency characteristics, a compact size with a pitch of 0.35mm, a stacking height of 0.6mm and a depth of 2.0mm. Metal guide ribs enhance the product’s robustness and substantially reduces the risk of connector damage when mating.

In recent years, new communication standards have been developing rapidly, resulting in an increase of required antennas based on product frequency needs. With this increase, products using conventional cable connectors have become crowded with wires. However, with the BM46 Series, transmission is possible in one package.

BM46 is an innovative product that contributes to increased board design capabilities, and is ideal for 5G and internet of things (IoT) technologies. It has already been adopted in a wide array of products and modules including smartphones and mobile routers.

Future Developments
In addition to the 60 position, 25mm mated height variant of the FX26 Series, Hirose is planning to develop additional pin counts and height variations. At present it is available in 20, 30, 40, 50, 60 positions; 12 to 25mm (12, 15, 18, 20, 25mm) mated height. With a reliable design that meets vehicle standards, FX26 can be used in other applications that are similarly exposed to harsh environments.

The spread of new communication standards, such as 5G, WiGig, and Low-Power Wide Area is expected to result in the development of new devices unlike anything ever seen before. BM46 is a small, robust, and high performance multi-RF board-to-board connector adaptable to these changes. Hirose aims to expand the use of BM46 beyond smartphones and routers to new markets in the future.
