SAN JOSE, Calif.–(Business Wire)–
Methode Power Solutions Group announces an innovative new class of patent
pending power connectors named “PowerBud”TM that successfully overcomes key
limitations of conventional power connectors. The PowerBud technology lowers
both contact resistance and contact normal force without increasing connector
size, a feat that counters conventional wisdom. The resulting connectors exhibit
lower insertion force, lower temperature rise, lower power loss and higher cycle
life than conventional high current connectors.

The PowerBud connector is initially available in a single-contact form called
the EBC (Embedded PowerBud Connector), with knurled outer side walls allowing
direct press-fit insertion into busbars, printed circuit boards and
FusionLugsTM. Installation or press-in is accomplished using any flat surface
and does not require any special tooling. The current rating is dependent on the
physical size of the pin and the heat-sinking capability of the mounting medium.
Embedded PowerBud connectors are available in pin sizes and ratings of 9.1 mm
(300A), 5.7 mm (240A), 3.6 mm (160A) and 2.4 mm (120A). The connector current
rating is dependent on the heat sinking capability of the mounting surface.
Typical contact resistance ratings at 100A are (9.1mm) 45µΩ, (5.7mm) 50µΩ,
(3.6mm) 90µΩ, and (2.4mm) 125µΩ.

Samples are available. Production leadtime is typically four weeks. Pricing
ranges from $5.90 to $6.91 in quantities of 1,000.

Technology origins

The PowerBud technology was originally pioneered by a Massachusetts Institute of
Technology (MIT) professor and graduate students investigating tribology, the
science and technology of interacting surfaces in relative motion, including
friction, lubrication and wear. The researchers developed a prototype power
connector with massively parallel points of contact which exhibited superior
qualities compared to conventional, commercial power connectors. Their connector
had very low contact resistance as well as very low insertion force without a
commensurate connector volume increase.

Methode acquired the technology in 2008 and focused on making the remarkable
connector more manufacturable. The result was the PowerBud, an evolution of the
original design with massively parallel points of contact, but using a
mechanical design that is adaptable to mass production.
