Handa Mechanical Connecting Spring is one of the reliable solutions to mechanical connection problems. Their small size, simple installation and versatility help you reduce the complexity and weight of your mechanical systems while improving their performance.
The Mechanical Connecting Spring has latch, lock and hold functions, is tool-free to install, and is rugged enough to withstand thousands of insert/remove cycles.


How to solve the mechanical connection problem
Handa mechanical connecting springs have multiple functions, which can solve various problems in mechanical connection and improve system performance and reliability.
Its flexible design and precision control capabilities make it ideal for solving complex mechanical connection problems.
Latching
Secure the two equipment components together, while facilitating multiple disassembly and replacement
Locking
Two device parts are permanently put together and cannot be removed without damaging the parts or springs
Holding
By using controlled spring forces to hold and align device components and facilitate sliding function
Locking & Quick-Release
Lock the components of the device together with the option to advance and bypass the lock for easy, low-force release

Compressive force performance of Mechanical Connecting Spring
Under compression, the spring exhibits unique deflection force characteristics. Unlike conventional springs, our springs maintain a near-constant force output over the entire operating deflection range, and this force characteristic remains stable over a wide temperature range. The spring design has the ability to resist compression deformation, and each coil can compensate each other to adapt to position deviations, dimensional tolerances and mating surface irregularities. By precisely adjusting parameters such as spring slots, spring dimensions and wire diameters, we can achieve precise force control for functions such as latching, locking, holding, connecting and disconnecting.
