Hollow D-Type Conductive Rubber Strip

Cat No:EWCMSM-0021

Description

Eata Electronic Hollow D-Type Conductive Rubber Strip is a specially designed conductive rubber product with a hollow structure and D-shaped cross-section. This shape design provides good elasticity, suitable for applications requiring tight fit and good conductive performance. Hollow D-type conductive rubber strip is typically composed of silicone rubber matrix mixed with conductive fillers (such as carbon black, metal powder, or metal-plated fibers) to impart required conductivity.

Structure and Design:

- D-Shaped Cross-Section: This cross-section shape can provide better conformability, especially when installed on flat or slightly concave surfaces. The D-shaped design helps increase contact area, thereby improving sealing performance.

- Hollow Structure: The internal hollow design reduces weight, decreases material usage, and lowers cost. It may also affect compression recovery performance and sealing effectiveness. The hollow structure can also reduce pressure changes during expansion or contraction, suitable for applications requiring pressure relief.

Material and Characteristics:

- Conductive Performance: The addition of conductive fillers gives hollow D-type conductive rubber strip excellent conductive performance, capable of effectively conducting current with low resistance. This enables it to have wide applications in fields requiring current conduction and static dissipation.

- Lightweight and Convenience: The hollow design significantly reduces material weight, facilitating carrying and installation. Meanwhile, the D-shaped cross-section also makes the rubber strip more convenient to install.

- Flexibility and Plasticity: The hollow structure imparts certain flexibility to the rubber strip, capable of adapting to installation surfaces with different curvatures, improving product applicability. Additionally, this flexibility helps maintain stable conductive performance during compression.

- Weather Resistance: Hollow D-type conductive rubber strip typically has good heat resistance, cold resistance, and corrosion resistance, capable of maintaining stable conductive performance and service life under different environmental conditions.

Application Scenarios:

- Electronic Devices Field

- In small electronic devices such as mobile phones and tablets, hollow D-type conductive rubber strip can be used for housing sealing and grounding. It prevents dust, moisture, and other contaminants from entering the device interior while ensuring timely static dissipation, improving device stability and safety.

- In large electronic devices such as server cabinets, it can be used for sealing and conductive connection between cabinet doors and cabinet bodies, ensuring internal electromagnetic shielding effectiveness, preventing electromagnetic leakage from interfering with surrounding equipment, while blocking external electromagnetic interference from affecting normal server operation.


- Automotive Industry

- In the automotive engine compartment, hollow D-type conductive rubber strip can be used for sealing and conductive connection between certain electrical devices. For example, between the engine control unit (ECU) and vehicle body, it prevents moisture and dust from entering the ECU while ensuring good electrical connection between ECU and vehicle body, ensuring signal transmission accuracy.

- At automotive door and body connection points, it serves sealing and conductive functions. Sealing prevents rainwater and wind noise from entering the vehicle interior, while conductivity helps dissipate automotive static electricity, improving riding comfort and safety.


- Aerospace Field

- In aircraft electronic equipment compartments, hollow D-type conductive rubber strip is used for device sealing and grounding. Since aircraft face complex electromagnetic environments during flight, good electromagnetic shielding and grounding are crucial for normal operation of aircraft electronic equipment. Meanwhile, its lightweight hollow structure also meets the strict weight requirements of the aerospace field for components.
