A cable tie (also known as a hose tie, zip tie, or by the brand name Ty-Rap) is a type of fastener, for holding items together, primarily electrical cables, and wires. Because of their low cost, ease of use, and binding strength, cable ties are ubiquitous, finding use in a wide range of other applications.
The common cable tie, normally made of nylon, has a flexible tape section with teeth that engage with a pawl in the head to form a ratchet so that as the free end of the tape section is pulled the cable tie tightens and does not come undone. Some ties include a tab that can be depressed to release the ratchet so that the tie can be loosened or removed, and possibly reused. Stainless steel versions, some coated with a rugged plastic, cater for exterior applications and hazardous environments.
Design and use
The most common cable tie consists of a flexible nylon tape with an integrated gear rack, and on one end a ratchet within a small open case. Once the pointed tip of the cable tie has been pulled through the case and past the ratchet, it is prevented from being pulled back; the resulting loop may only be pulled tighter. This allows several cables to be bound together into a cable bundle and/or to form a cable tree.
A cable tie tensioning device or tool may be used to apply a cable tie with a specific degree of tension. The tool may cut off the extra tail flush with the head in order to avoid a sharp edge which might otherwise cause injury. Light-duty tools are operated by squeezing the handle with the fingers, while heavy-duty versions can be powered by compressed air or a solenoid, to prevent repetitive strain injury.
In order to increase resistance to ultraviolet light in outdoor applications, nylon containing a minimum of 2% carbon black is used to protect the polymer chains and extend the cable tie's service life. Blue cable ties are supplied to the food industry and contain a metal additive so they can be detected by industrial metal detectors. Cable ties made of ETFE (Tefzel) are used in radiation-rich environments. Red cable ties made of ECTFE (Halar) are used for plenum cabling.
PlastiCuffs are handcuffs based on the cable tie design and are used by law enforcement to restrain prisoners. Cable ties are also sometimes used to prevent hubcaps (also known as wheel trims) from falling off a moving vehicle, and some are sold specifically for this purpose.
Cable ties were first invented by Thomas & Betts, an electrical company, in 1958 under the brand name Ty-Rap. Initially they were designed for airplane wire harnesses. The original design used a metal tooth, and these can still be obtained. Manufacturers later changed to the nylon/plastic design.[self-published source]
Over the years the design has been extended and developed into numerous spin-off products. One example was a self-locking loop developed as an alternative to purse-string suture in colon anastomosis.
Ty-Rap cable tie inventor, Maurus C. Logan, worked for Thomas & Betts and finished his career with the company as Vice President of Research and Development. During his tenure at Thomas & Betts, he contributed to the development and marketing of many successful Thomas & Betts products. Logan died on 12 November 2007, at the age of 86.
The idea of the cable tie came to Logan while touring a Boeing aircraft manufacturing facility in 1956. Aircraft wiring was a cumbersome and detailed undertaking, involving thousands of feet of wire organized on sheets of 50-foot-long plywood and held in place with knotted, waxcoated, braided nylon cord. Each knot had to be pulled tight by wrapping the cord around one's finger which sometimes cut the operator's fingers until they developed thick calluses or "hamburger hands." Logan was convinced there had to be an easier, more forgiving, way to accomplish this critical task.
For the next couple of years, Logan experimented with various tools and materials. On June 24, 1958, a patent for the Ty-Rap cable tie was submitted.
Within research, there are self-locking loops, based on the construction of the traditional cable tie, designed for surgery. The device is intended for ligation purposes, by compressing tissue hemorrhage is prevented. The same material is used as in surgical suture (resorbable polymers), therefore the implant can be left in the body where after the material is resorbed by the tissue.
Traditional cable ties, due to their non-resorbable material, may not be left in the body permanently due to the risk of development of chronic granulomas. In urology, short term use of cable ties have been described at partial kidney resection.
Cable ties are generally single-use devices however the larger ones can be reopened with little or no damage by inserting and turning a small flat-head screwdriver inbetween the ratchet and the pawl. Some models have a button to release the pawl and allow re-use.
Types of specialty cable ties
- Beaded cable ties: Beaded design allows them to be releasable and reusable
- Releasable cable ties: Reusable cable ties with a releasable ratchet
- Ladder style cable ties: For intermediate bundling and retail applications
- Identification cable ties: Built-in flags for written or printed identification
- Parallel entry cable ties: Tamper-proof, low profile heads
- Tear-off cable ties: Quick release design requires no cutting tools
- Pull-tight seals: Tamper-evident seals
- Steggel ties: Heavy duty, multipurpose ties
Other methods of bundling cable together securely and semi-permanently include cable lacing, strapping, binding knots such as the surgeon's knot or constrictor knot, Velcro brand hook-and-loop strips, conveyor belt hooks, twist ties, Rapstrap fasteners, or metal buckle.
