Who Invented the Cable Tie?

The cable tie, a simple yet indispensable tool, was invented over 60 years ago by Maurus C. Logan, who worked for Thomas & Betts, an electrical company based in Memphis, Tennessee. Throughout his career, Logan developed numerous products, but the cable tie became his most successful and enduring invention.

As with many impactful inventions, the cable tie's simplicity is what makes it exceptional. Originally known as the Ty-Rap, it was patented in the same year it was introduced, quickly establishing itself as an essential tool in various industries and households worldwide. Logan's innovative spirit eventually led him to become the Vice President of Research & Development at Thomas & Betts.

THE LIGHT BULB MOMENT:

Logan's moment of inspiration occurred while he was visiting a Boeing aircraft facility. He observed the labor-intensive process of bundling thousands of feet of cables with wax-coated cord. Aircraft workers often sustained injuries to their hands, resulting in thick calluses over time. Realizing there had to be a more efficient solution, Logan set to work on his design for the cable tie.

A NEW & CHEAPER DESIGN:

When first launched, the cable ties were branded as Ty-Raps, created specifically for the aeronautical industry, to manage wire and cable harnesses. Initially, they consisted of two components: a molded plastic part and a metal component called a pawl, which facilitated locking. This design proved inefficient and costly, leading manufacturers to switch to entirely nylon and plastic versions, eliminating the metal component.

THOMAS & BETTS:

Thomas and Betts is renowned for creating connectors and components for electrical and communication sectors. Founded by Robert Thomas and Hobart Betts, who began selling conduit during the early introduction of incandescent lighting in New York City, the company has evolved to specialize in wire and cable management. In 2012, it was acquired by Swedish-Swiss multinational corporation ABB for $3.9 billion.

Remembering Maurus C. Logan:

Logan's son, Robert, fondly recalled, "My dad didn't have a lot of formal education but was the most ingenious person I ever met. He consistently sought improvements, and the invention of the cable tie exemplifies his innovative mindset." While Memphis is often associated with Elvis and Johnny Cash, it is also the hometown of Maurus C. Logan, who passed away at age 86 in November.

The Original Design:

Cable ties were initially designed for electrical and automotive applications, specifically for bundling and securing electrical wiring. They effectively organize numerous cables into manageable bundles, and their versatility makes them suitable for both indoor and outdoor environments. In recent years, cable ties have found their way into countless households in the UK, where they are regularly employed for various simple tasks.

Size & Strength:

Cable ties come in a broad range of sizes and tensile strengths, essential for securely fastening cables of all dimensions—from small wires to large and heavy cables. Larger cables require correspondingly larger ties to guarantee their proper bundling.

Diversity in Application:

While cable ties are prevalent in automotive, electrical, telecommunications, and transportation industries, their utility extends to homes, DIY projects, biking, and hiking, serving diverse purposes across the board. Constructed from robust nylon polyamide, they function effectively in both indoor and outdoor applications.

How They Work:

Cable ties have a straightforward design and maintain a similar structure and appearance worldwide. They feature a row of serrated teeth on one side that locks into a head on the opposing side. To use a cable tie, simply loop it around the items to be fastened and feed the serrated end through the head. The design allows the teeth to move freely while tightening, forming a secure lock that cannot be released unless the tie is cut.

Types Of Cable Ties:

As cable ties have permeated multiple industries, manufacturers have developed a wide range of specialized and colored variants. Nowadays, these items come in a myriad of colors, with unique types available such as: stainless steel, screw mount, double loop, marker, push mount, and releasable cable ties.

Nylon 66:

Nylon 66, also known as Nylon 6/6, is the preferred material for standard plastic cable ties. This synthetic compound is produced at an average rate of 2 million tons per year and is favored due to its remarkable mechanical strength and rigidity. It performs well in extreme temperatures and demonstrates excellent chemical resistance, maintaining integrity over time with minimal degradation.

Black is Back:

Black cable ties are often utilized for outdoor applications due to their UV resistance. Like all cable ties, they are also resistant to oils, grease, and environmental contaminants. With a low friction coefficient and outstanding impact and abrasion resistance, these lightweight, strong, and economical ties explain their global popularity.

CORRECT STORAGE - COOL & DRY:

Optimal storage is vital for preserving cable ties. Manufacturers recommend storing them in a cool and dry environment to prevent oxidation and to ensure they remain in good condition for future use. In situations requiring superior corrosion resistance and durability against harsh weather, stainless steel cable ties are recommended. While nylon 66 offers weather resistance, stainless steel provides an extra layer of reliability.

SECRET TO SUCCESS:

The success of the cable tie is attributed to its diverse range of applications and cost-effectiveness. Wherever cable management is necessary or items need to be fastened, cable ties excel. Once secured, a cable tie remains firmly in place. When the nylon strap is inserted into the ratchet head, it locks, ensuring strength and reliability—often the simplest designs yield the most significant results.
