1. Product classification

Spiral tube shielding gaskets are divided into beryllium copper spiral tube gaskets and stainless steel spiral tube shielding gaskets according to different materials.

Beryllium copper spiral tubes are high-performance electromagnetic shielding pads. Made of high-quality beryllium copper material, they have excellent elasticity and resistance to permanent compression deformation.

They can quickly recover to their original shape after being squeezed by external force, and can adapt to gaps of different shapes and sizes to ensure good contact and shielding effects; the surface of the spiral tube is tinned or nickel-plated to further improve its conductivity and shielding performance, and the edge-coated pads have strong

resistance to electrochemical corrosion in humid and salt spray environments.

Stainless steel spiral tube shielding gaskets are spiral tube shielding strips made of stainless steel.

Stainless steel spiral tubes have excellent elasticity and compressive resistance, and can achieve significant support and retraction functions. They can be installed on plates of any thickness without additional support. In addition, stainless steel spiral tubes can also provide excellent shielding performance to protect electronic equipment from electromagnetic interference.

 

Introduce

The shielded spiral tube gasket is made of highly elastic tin-plated beryllium copper, nickel-plated beryllium copper, stainless steel and other materials. This unique structure gives it an excellent electromagnetic wave shielding effect. It can effectively block the interference of external electromagnetic waves and ensure the normal operation of the equipment in a complex electromagnetic environment. Whether it is high-frequency or low-frequency electromagnetic waves, it can be efficiently shielded by it, providing reliable protection for equipment that requires high electromagnetic wave shielding performance.

Main functions of shielded spiral tube gaskets

Electromagnetic shielding: The most important function is electromagnetic shielding. Through the metal spiral tube structure, it can effectively isolate external or internal electromagnetic interference, protect electronic equipment from electromagnetic radiation interference, and ensure the normal operation of the equipment.

Reduce electromagnetic radiation leakage: When used in a pipeline system for transmitting signals or currents, the shielded spiral tube gasket can prevent the leakage of electromagnetic radiation of signals or currents, avoiding interference with the surrounding environment or equipment.

Improve electromagnetic compatibility (EMC): Applied to industrial equipment, communication equipment, medical equipment and other fields to ensure that the equipment complies with EMC (electromagnetic compatibility) standards and meet legal and safety regulations.

Structural protection and durability: Spiral pipe gaskets can also provide physical protection to prevent equipment from being damaged by friction, collision or other physical damage, and enhance the durability of pipes or equipment.

Structure and materials of shielded spiral pipe gaskets

The structure of shielded spiral pipe gaskets usually includes two parts:

Wire mesh layer: The wire mesh is woven from highly conductive metals (such as stainless steel, copper, aluminum, etc.) and is responsible for providing electromagnetic shielding. The tightness and material of the wire mesh determine its shielding effectiveness.

Elastomer or protective layer: The inner and outer surfaces of the spiral pipe generally have a layer of elastomer (such as rubber, silicone, etc.) or protective layer, which mainly plays a role in waterproofing, corrosion resistance and shock resistance. Elastomer materials can also provide a certain buffering effect and increase the durability of the gasket.

Shielded spiral tube gaskets are high-performance electromagnetic shielding gaskets. This shielding gasket material is an ideal shielding material for military and aerospace projects, as well as some civilian electronic equipment that requires efficient shielding and sealing, and can be widely used in shielding problems that other gaskets cannot solve. The shielding effectiveness of this sealing gasket is 86dB to 165dB.

Stainless steel spiral tubes are also high-performance electromagnetic shielding gaskets. This product is very suitable for civilian applications and complies with European Directive 83528. These gaskets can provide more than 95 dB shielding quality at 1GHz.

Our company provides professional shielding spiral tube gasket customization services, aiming to provide customers in different industries with efficient electromagnetic shielding and protection solutions. Through customization services, we can design and manufacture shielding spiral tube gaskets that meet their special application environments according to the specific needs of customers, ensuring that the performance, size and applicability of the products are perfectly matched to help customers deal with complex electromagnetic interference (EMI) problems.
