The inclined coil spring, also known as spring finger finger, touch finger spring, touch spring, can transmit strong current in a small space, and can also be used as a simple mechanical connection. There are no restrictions on its use, and it is suitable for use in a variety of static or dynamic medium and high voltage environments.
The size of the spring fingers and the independent number of coil turns make the spring suitable for a variety of electrical touch planning and can be used electrically or EMI shielded with a large touch point current carrying capacity. Each coil will independently compensate for touch and appearance changes, and it promises public service between a wider range of accessories. Multiple touch points increase the conductivity, together with its use operating temperature is relatively low, so the service life is longer.
Spring touch skills are used in power touch in a variety of occupations, including medical electronics, medical devices, aerospace and defense, power and automotive, and more.
The advantages of spring contact fingers are as follows:
1. Simple structure, small size, less materials, low cost, to meet the requirements of small space size in equipment planning, suitable for compact planning, less number of components, simplified the planning of connector materials.
2. Multi-touch, high concentration, can achieve almost lossless touch. Ensure large current carrying capacity, good electrical conductivity, high electric and thermal stability.
3. The touch pressure of each touch point is not high, and it has good wear resistance.
4. The unique structure makes it have a wide working range, promises to have a large public service on the touch surface, has greater adaptability to processing errors and installation errors, and is more suitable for large-scale production.
Application range of helical contact finger springs:
1. High and medium voltage switch
2. Busbar connectors
3. High current connector
4. Solid pole post
5. High-voltage chain end parts
6. Fuse connector
7. Mechatronic applications
