Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, in particular to a spring sheet structure for connecting terminals. Background Art

[0002] In the connecting terminal, the function of the spring is to adapt to the target connecting parts of different shapes and sizes through the elastic deformation of the spring when the connecting terminal contacts the target connecting part, so as to achieve a reliable electrical connection; however, when the spring is pressed and moved, the spring foot of the existing spring structure contacts a large area with the base plate, and a large friction force is generated between the spring foot and the base plate, resulting in the fluctuation of the elastic force of the spring during the compression process.

[0003] A Chinese patent discloses a spring structure and a connecting terminal for a connecting terminal (authorization announcement number CN208904234U). In the patented technology, a convex rib with a smooth surface is arranged on the bottom plate. When the spring is compressed, the spring foot slides along the convex rib, thereby reducing the contact area between the spring foot and the bottom plate, and reducing the friction between the spring foot and the bottom plate, so that the elastic performance of the spring is more stable; however, it has certain disadvantages: the convex rib cannot be replaced, and the surface of the convex rib is easily worn during long-term use, which leads to an increase in the friction when contacting the spring foot, thereby affecting the elastic performance of the spring.
