4. History of Hyperboloid
Patented by FRB in 1960’s
Early 70’s: Original US Licensees: IEH, Smiths Interconnect, Curtiss-Wright
Today: Only Manufactures of Hyperboloid connectors are IEH and the divisions of Smiths (Hypertac Ltd, Hypertronics)

5. Hyperboloid Technology

6. Hyperboloid Concept
The Hyperboloid-shaped sleeve is formed by straight wires strung at an angle to the longitudinal axis. This geometry provides for a design which has a decreasing circumscribed circle when viewed from the entry
When the pin is inserted into this sleeve, the wires stretch, well within elastic limits, to accommodate it. In doing so, the wires wrap themselves around the pin, providing a number of continuous line contact paths

7. Hyperboloid Construction
Wires strung on an internal wire carrier (inner sleeve), and enclosed by a front outer ring (front sleeve) and the terminal. Joints are calculated interference fits, insuring gas-tight interfaces between all elements of the Hyperboloid construction
The unique geometry, precision processing, and careful attention to quality result in a highly desirable contact design which provides:

8. Low Insertion/Extraction Forces
Feature
Wire basket expands to envelop mating pin when inserted.
Benefit
Less resistance in pin-socket interface, thus less force required to mate and demate, especially in high pin count connectors

9. Contact Life Feature Benefit
Unlike the “plow and scrape” action of common designs, Hyperboloid’s wiping action reduces wear on the contacts surfaces.
Benefit
Standard contacts are rated to last 500 mating cycles.
Hyperboloid contacts are rated for 100,000 mating cycles.

10. Higher Current Ratings
Feature
Hyperboloid wire system envelops mating pin, thus more lines of contact between pin and socket
Benefit
Greater current-carrying capability, at ambient temperature rise

11. Impervious to Shock & Vibration
Feature
The low mass and resulting low inertia of the wires allows them to follow the most extreme excursions of the pin without loss of contact. Test exceed 300 g’s without discontinuity.
Benefit
Guaranteed electrical continuity regardless of the direction
or intensity of external and internal forces.

23. HUB ZONE CERTIFIED
Competitors
Very little overlap between IEH and Hypertronics product lines
As an M55302 QPL provider, IEH competes mainly with Airborn, Incon and Continental connector. IEH – Airborn comparison as follows:
Airborn W Series = IEH HGM Series
Airborn RM2 and RM3 Series = IEH HRM Series
Airborn RM4 Series = IEH HMM Series
