Cable Strain Relief (SR) Assembly

A Cable Strain Relief, also known as a cable gland or cord grip, is a device used to secure and protect cables or wires that are connected to electrical equipment. It is designed to relieve the strain on the cable by providing support and preventing it from being pulled out or damaged due to tension, vibration, or movement.

Cable strain reliefs are commonly used in various industries such as manufacturing, automotive, telecommunications, and electronics. They play a crucial role in ensuring the longevity and reliability of electrical connections by reducing stress on the cables.

These devices typically consist of two main components: a body and a sealing nut. The body houses the cable while the sealing nut secures it in place. The design may vary depending on specific requirements such as environmental conditions (e.g., waterproofing) or cable type (e.g., fiber optic cables).

In addition to providing mechanical support, cable strain reliefs also offer protection against dust, moisture, chemicals, and other external factors that could potentially damage the cables. This helps maintain optimal performance and prevents costly repairs or replacements.

Installation of a cable strain relief involves inserting the cable through an opening in the body and tightening the sealing nut until it forms a tight seal around the outer sheath of the cable. This ensures that no excessive force is applied directly onto sensitive internal wiring connections.

Cable Strain Relief (SR) Assembly Cases

SR for cable stop

The SR on the cable serves a function in ensuring that the cable remains securely in place and does not move excessively in any direction. This is designed to provide stability and prevent unnecessary strain or stress on the cable, which can lead to damage or disconnection.

SR for catch to the box

The SR on the cable is sometimes designed to secure it to the enclosure box, particularly when the cable is soldered to the PCB and the soldering point is not very strong. In such cases, this Strain Relief can help reduce tension force and protect the connection.

SR for fix the magnet ring

The cable, such as a VGA cable, should be equipped with a magnet ring. In order to secure the magnet ring onto the cable, the most effective method is to overmold it with a strain relief (SR).

SR for durability

One of the primary functions of cable SR is to ensure durability and longevity, not only for the cable itself but also to protect the connections it is attached to. This design feature plays a crucial role in preventing damage or wear and tear that can occur due to constant movement, tension, or stress on the cables.

SR Function
The strain relief or cable gland can protect the wires and cables by securing the wire and cable to the electrical equipment panel. It helps prevent stress and damage as it passes through the equipment panel. Although it doesn't relieve strain on the cable when it exits the equipment, it does alleviate strain on the electrical connection and circuitry inside.

Different cable OD need a different SR
The SR is overmolded onto the cable, ensuring a secure attachment. As a result, each unique SR fits a specific OD cable. If the cable's outer diameter changes, it may not fit as tightly, necessitating the creation of new overmold tools to accommodate the new cable.

SR Test
The SR test usually assesses the durability by conducting the swing test, which typically involves approximately 3000 to 5000 cycles. The final outcome is influenced by various factors such as weight load, testing angle, material hardness, and so on.
