What is a touch spring?

Touch finger spring is also called touch finger spring, spring touch finger, inclined coil spring. The contact spring is a ring spring that can carry a strong current in a small space, but can also be used as a purely mechanical connection. It is suitable for use in a variety of static or dynamic medium and high pressure environments. It can be used in the robotics industry, automotive industry, aerospace industry, petrochemical industry, medical industry, submarine industry and so on. This new type of spring has a unique load - deformation curve, wide operating range, high allowable compression of the spring. A nearly constant elastic force can be maintained over a large deformation range. The coil is elliptical and inclined, and when compressed, each coil will deform individually. No matter which part of the coil deforms, the whole spring will react, so as to achieve a consistent load at each contact point.

So what are the advantages of this new spring touch? The advantages of the touch spring are as follows:

1, simple structure, small volume, less material, low cost; It meets the requirement of small space size in device design and is suitable for compact design. The minimum number of components simplifies the design of connected devices.

2, multi-point contact, high concentration force, can achieve almost no loss contact. Ensure large load capacity; Good electrical conductivity, high electric and thermal stability.

3, the contact pressure of each contact point is not high, with good wear resistance.

4, the unique structure makes it have a wide range of work; Large tolerances are allowed on the contact surface; It is more adaptable to machining error and assembly error and more suitable for mass production.

Application range of touch spring:

1, high pressure switch

2. Bus connecting piece

3, high current connector

4, solid sealing pole

5, the end of the high voltage chain

6. Fuse connector

7. Mechatronics applications
