Face-mounted spring contacts are typically flat and made of elastic materials, achieving electrical connection through axial elastic deformation. Installed between two planes requiring electrical connection, they undergo elastic deformation when subjected to external forces (such as compression during assembly). Through their own elastic structure, they generate axial contact pressure, enabling the contacts to fit tightly against the two planes and form multiple contact points. These parallel-connected contact points constitute a conductive path, thereby realizing the transmission of electrical energy or signals.

Thanks to the elasticity of the spring, they can compensate for factors like plane machining tolerances, assembly deviations, and vibration-induced displacements during use, while maintaining stable contact pressure continuously to ensure the reliability of electrical connections. Additionally, in scenarios requiring electromagnetic shielding, face-mounted spring contacts can also fill gaps between planes to play an auxiliary role in electromagnetic shielding.

Flat spring contacts adopt a multi-point distributed elastic contact structure, which can adapt to minor unevenness or deformation on the surface of planar conductors and form uniform contact pressure. This effectively reduces fluctuations in contact resistance. Even after long-term use, they can avoid contact failure caused by oxidation and wear, making them particularly suitable for high-precision, low-loss current transmission scenarios.

Strict alignment accuracy is not required, as they can absorb installation deviations within a certain range (e.g., parallelism and flatness errors), reducing adjustment costs during assembly. Meanwhile, they are compatible with planar conductors of different sizes, and their versatility is superior to that of traditional rigid connections.

The elastic deformation of the spring itself can buffer the impact of external forces such as vibration and shock, preventing loosening or poor contact at the connection part. They are especially suitable for high-frequency vibration environments like rail transit and industrial equipment.

The distributed force-bearing structure formed by multi-point contact reduces the concentration of local contact pressure and lowers Joule heat accumulation. Combined with the large-area heat dissipation characteristic of planar conductors, the current-carrying capacity can be stably improved, making them suitable for medium and high-current scenarios.

The elastic preload of the spring contacts can compensate for long-term rotational wear or contact component wear, extending the service life of the overall connection structure and reducing the frequency of maintenance and replacement.
