Hypertac Hyperboloid
Technology
Smiths Interconnect offers an extensive range of superior contact technologies suitable for standard and custom
solutions. Hypertac
®
(HYPERboloid conTACt) is the original superior performing hyperboloid contact technology
designed for use in all applications and in harsh and demanding environments where high
reliability and safety are critical. The inherent electrical and mechanical characteristics
of the Hypertac hyperboloid contact ensures unrivalled performance in terms
of reliability, number of mating cycles, low contact force and minimal
contact resistance. The shape of the contact sleeve is
formed by hyperbolically arranged contact wires,
which align themselves elastically as
contact lines around the pin, providing
a number of linear contact paths.
Features Benefits
Low insertion/extraction forces
The angle of the socket wires allows tight control of the pin
insertion and extraction forces. The spring wires are smoothly
deflected to make line contact with the pin.
High density interconnect systems
Significant reductions in size and weight of sub-system designs.
No additional hardware is required to overcome mating and
un-mating forces.
Long contact life
The smooth and light wiping action minimizes wear on the
contact surfaces. Contacts perform up to 100,000 insertion/
extraction cycles with minimal degradation in performance.
Low cost of ownership
The Hypertac contact technology will surpass most product
requirements, thus eliminating the burden and cost of having to
replace the connector or the entire subsystem.
Lower contact resistance
The design provides a far greater contact area and the wiping
action of the wires insures a clean and polished contact
surface. Our contact technology has about half the resistance of
conventional contact designs.
Low power consumption
The lower contact resistance of our technology results in a
lower voltage drop across the connector reducing the power
consumption and heat generation within the system.
Higher current ratings
The design parameters of the contact (e.g., the number, diameter
and angle of the wires) may be modified for any requirement.
The number of wires can be increased so the contact area is
distributed over a larger surface. Thus, the high current carried by
each wire because of its intimate line contact, can be multiplied
many times.
Maximum contact performance
The lower contact resistance of the Hypertac contact reduces
heat build-up; therefore Hypertac contacts are able to handle
far greater current in smaller contact assemblies without the
detrimental effects of high temperature.
Immunity to shock and vibration
The low mass and resultant low inertia of the wires enable
them to follow the most abrupt or extreme excursions of the pin
without loss of contact. The contact area extends 360° around
the pin and is uniform over its entire length. The 3 dimensional
symmetry of the Hypertac contact design guarantees electrical
continuity in all circumstances.
Reliability under harsh environments
Harsh environmental conditions require connectors that will
sustain their electrical integrity even under the most demanding
conditions such as shock and vibration. The Hypertac contact
provides unmatched stability in demanding environments when
failure is not an option.
