This advanced connector technology has positioned IEH as a key player in various industries, providing solutions that meet the most stringent requirements and operate effectively in the harshest environments.

Company History

IEH Corporation began its journey in 1941 as a tool and die maker in New York City. Founded by Louis Offerman and his sons, Bernard and Seymour, the company initially supported the war effort during World War II by producing precision tools and dies for military equipment. During this foundational period, he established IEH’s commitment to quality and precision, defining its future endeavors.

Following the war, IEH transitioned to manufacturing transistors and tube sockets for the burgeoning consumer electronics industry. This move marked the beginning of the company’s expansion into electronic components. By the 1960s, IEH had further diversified its product line to include cathode ray tubes (CRTs) for the US television industry. This period of growth was significant, as IEH became the largest manufacturer of CRT sockets globally, cementing its reputation as an industry leader.

In the late 1960s, IEH acquired a license to manufacture Hyperboloid sockets, which expanded their product offerings to include printed circuit board connectors for military and aerospace applications. This strategic move allowed IEH to leverage its expertise in precision manufacturing and enter new, high-demand markets. Today, IEH continues to be a global leader in producing hyperboloid connectors and contacts, and it is known for its superior performance in challenging environments.

Hyperboloid Technology

Introduction to Hyperboloid Technology

IEH Corporation made a significant stride in the late 1960s by acquiring a license to manufacture Hyperboloid sockets. This technology marked a pivotal moment for IEH, enabling them to advance into high-performance connector solutions.

Application in Military and Aerospace

Hyperboloid connectors are crucial in military and aerospace applications, particularly under Mil-DTL-55302 specifications. These connectors are designed to withstand rigorous conditions and stringent requirements of these industries. They ensure reliable and secure connections essential for critical operations and mission success. The robustness and durability of Hyperboloid connectors make them indispensable in environments where failure is not an option.

Technical Overview

The Hyperboloid contact design is characterized by a unique configuration of angled straight wires that form a hyperboloid-shaped sleeve. This design enhances electrical performance and mechanical reliability compared to traditional connectors. The angled wires create multiple contact points along the mating surface, ensuring consistent connectivity and reducing the risk of signal interruption or loss.

Unique Design

Its hyperboloid-shaped sleeve is at the core of hyperboloid technology, formed by the precision placement of straight wires at specific angles. This design feature allows for a higher density of contact points than standard connectors. The hyperboloid shape ensures a secure and stable connection even in environments prone to vibration, shock, and extreme temperatures.
