【Product】Recommended Compression for E密斯 Grounding Clip

Grounding FuzesThe selection of compression ratio requires comprehensive consideration of multiple factors:

Firstly, the requirement for contact resistance must be considered; insufficient compression may lead to poor contact and increased resistance, while excessive compression could cause excessive wear and potential breakage or damage to the spring and contact surface. Secondly, the limitations of the installation space should be taken into account. If space is limited, excessive compression may not be achievable.

In electronic devices, if an extremely low contact resistance is required and space permits, a larger compression amount can be chosen. For small devices with strict size requirements, the compression amount should be minimized while still meeting the contact requirements. Additionally, the material and elastic properties of the spring clip must be considered. The optimal compression range varies depending on the material and design of the spring clip. Generally, for ground spring clips in common small electronic devices, a compression amount between 10% and 30% of their free height is likely appropriate. For instance, if the free height of a ground spring clip is 10mm, the compression might be around 1mm to 3mm. However, in high-precision devices where contact resistance is extremely critical, the compression amount may reach 40% or more of the free height. In applications with limited space or where spring force requirements are more lenient, the compression amount might be around 5% to 15% of the free height.

In summary, the selection of the compression amount for the ground fragments should be comprehensively assessed based on the aforementioned factors, and determined through experimentation and testing for the most suitable compression. Eimis currently offers over 100 standard SMD fragment options for selection, and can recommend appropriate products based on customer requirements.

ConfirmedGold-plated ShrapnelThe optimal compression ratio can be achieved through the following methods:

Firstly, conduct theoretical calculations. Utilize mechanical formulas to initially estimate the stress, strain, and contact conditions of fragments based on their material properties, geometric shapes, and expected loads. However, this method is often not precise enough and should only be used as a reference. Secondly, perform simulation analysis. With Finite Element Analysis (FEA) software, simulate the stress, strain, and contact conditions of fragments under different compression levels to determine an optimal compression range. Lastly, conduct experimental tests. Fabricate multiple samples with different compression levels and test them under actual working conditions, measuring key parameters such as contact resistance and changes in spring force.

For instance, in the grounding stud tests for electronic equipment, experimental groups with different compression levels can be set up to monitor the grounding performance of the device under various working environments and over time. At the same time, consider the product's lifespan requirements. If the product needs to operate stably over a long period, a compression level that maintains performance throughout a longer working cycle may be required.
