Wire strain relief cable connector flex type

The classic look of the metal strain relief design makes it very appealing on the consumer end.Д«ut nowadays, they have been almost replaced by plastic designs which are more safe and beneficial for all types of required purposes of the strain reliefs. Some metal strain reliefs may be made of plated steel and nickel-plated material.

Metals used for the manufacturing of this type include steel, aluminum, stainless steel or metal alloy brass. It is also installed for reinforcement of the electrical connection of the cord which in fact protects the conductors against twisting or pulling. Metal strain reliefs provide extra protection against over bending of the flexible cables and also protect them against cutting due to sharp edges of other attached devices. This metal spring is installed at the junction of cable and connector to serve the above-mentioned purposes. This is the older design of strain reliefs and manufactured in the form of spring which surrounds the cable at the connection point. Metal Strain Relief DesignДЄs the name indicates, this type of strain relief fitting is designed based on the plastic material. Generally, due to safety reasons, plastic relief designs are more preferred. The electrical conduits are made of metal as well as plastic but serve the same purposes. Some strain reliefs can be made by both plastic and metal without reducing their effectiveness. Generally, they are made up of aluminum, brass (copper and zinc alloy), nylon, steel, stainless steel, and various polymer materials (polyester, PTFE or PVC).Дepending on the type of materials used for strain relief devices, it is divided into two types of designs which include metal strain relief design and plastic strain relief design.ДЄ specific type of design is selected based on customer requirements or required installation features. Strain Relief DesignsДЄs 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.В 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.ДЇlex style is generally used to protect the cables from breakage by providing extra bending relief to them.Д«oth 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.Д«oth 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.ДЄnother 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.ДЇailure 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.
