Spring contact finger: In life, spring contact finger structure is used in the fields of automobiles, electronic equipment, power connectors, etc. The head and end of this spring are welded to form a spring ring. When we encounter this kind of part structure, we often don't know it very well, and we will have questions about "what is this?" Let's take a look at the "spring contact finger" with the editor to solve the doubts and puzzles in my heart.

Spring touch fingers:In life, spring contact finger structure is used in the fields of automobiles, electronic equipment, power connectors, etc. The head and end of this spring are welded to form a spring ring. When we encounter this kind of part structure, we often don't know much about it, and we will have questions about "what is this for". Let's take a closer look at "spring contact finger" with Xiaobian to solve our doubts and puzzles.

Spring contact finger is also called inclined coil spring and ring spring. Its coil is elliptical and inclined. When compressed, each coil will deform separately. No matter which part of the coil deforms, the whole spring will react, so as to realize the consistent load on each contact point, so that the whole can maintain a nearly constant elastic force.

Due to its structural characteristics, there is no restriction on the scope of use. It is suitable for use in a variety of static or dynamic medium and high voltage environments. It can be used purely for mechanical connection or for transmitting strong current. It is widely used in automobiles, electronic equipment, high current connections, high and medium voltage switches and other fields.

Spring touch fingerThanks to its powerful performance. The production structure is simple, small in size, small in material, and low in cost. It can meet the requirements of device designers for small space and small size. It is suitable for compact design. Therefore, it can be simplified and designed into precision devices with the least number of parts. Ring design, to ensure that the spring contact finger multi-point contact, high concentration can achieve almost no loss of contact, to ensure a larger current carrying capacity and stable conductive performance, and each contact point load is consistent so that the spring has better wear resistance. Finally, as far as production is concerned, the unique structure allows it to have a wide working range, allowing larger tolerances on the joint surface, and has greater adaptability to processing errors and assembly errors, making it more suitable for mass production.

In order to letSpring touch fingerCan play a full role in the device, not only in the material needs to be carefully selected, but also in the design to keep improving. The inclination angle α of the spring affects the stress of the spring. The greater the angle α, the greater the deformation resistance. On the contrary, reducing the angle α can effectively reduce the deformation force. For dynamic connection, under the condition that the spring contact finger is fully in contact with the conductor and the guide sleeve, the stress of the spring contact finger is as small as possible; for static connection, the stress can be appropriately increased to further reduce the contact resistance.
