Strain Relief DesignsĪs discussed earlier, strain reliefs are designed in different shapes, sizes and are manufactured by using various types of materials. Types of strain reliefs include wire ties, cable glands, cable bushings, and Romex connectors. They all are manufactured according to the size of required fittings and in accordance with the required shape. The dome-style device is generally used where high protection thus high rigidity is required to protect the cable against cutting due to sharp edges of attached device or electrical panel and it is fitted at the point of connection.įlex style is generally used to protect the cables from breakage by providing extra bending relief to them.īoth styles are very important and equally used in various hardware products to increases their life cycle and also increases the quality as well as safety of electrical cables or wires.īoth types of shapes can be made up of aluminum, brass, nylon, steel, stainless steel, and various polymer materials.

The classification of strain reliefs depend on rigidity or flexibility and is in accordance with their styles. These devices may be used to provide the liquid-tight seal at the connection region. The major purpose of strain reliefs includes extra protection against over bending of the flexible cords or cables or protection against cutting due to sharp edges of other attached devices.Īnother objective of using strain relief devices is the reinforcement of the electrical connection of cord or wire which protects the conductors against twisting or pulling. High stresses and fatigue is produced in the cable-connector region due to tight bends and a combination of stiff-flexible part of that device or simply cable.įailure increases as bend become tighter because of the inverse relation of strain with a radius of curvature. The hardware products which require strain relief instruments include electrical cables, wires or cords, tubes, and various types of accessories used in medical equipment. All the hardware products which experience any type of tensions or stresses during their lifetime are equipped with metal or plastic strain relief devices. These relief devices also prevent the conductor inside electrical cables.

Strain relief is mainly used to protect electrical cables against stresses and tensions which could break the connection between cable and connector or plug. Strain reliefs are designed in different shapes, sizes and are manufactured by using various types of materials. Various flexible hardware products may experience forces of push or pull during which are absorbed by the strain reliefs and these products are protected from generated mechanical stresses. Strain relief is a mechanical fixture that is used to protect various flexible products (cables, cords, or wires) against their longitudinal motion and thus increasing the lifeline of these flexible products.
