[0025] Please refer to Figure 1-Figure 2 The utility model provides a multi-contact spring piece to solve the problem of how to achieve multi-contact conduction.

[0026] For details, please refer to Figure 1 A three-dimensional diagram of a multi-contact spring sheet provided in an embodiment of the utility model, the utility model provides a multi-contact spring sheet, comprising: a plate-like base 10, a first extension portion 20 formed by bending downward and extending from the side of the plate-like base 10, a second extension portion 30 formed by vertically bending and extending from the top of the first extension portion 20, a first contact arm portion 40 formed by bending downward and extending from one side of the second extension portion 30, and a second contact arm portion 50 formed by bending downward and extending from the other side of the second extension portion 30. In this embodiment, the plate-like base 10, the first extension portion 20, the second extension portion 30, the first contact arm portion 40 and the second contact arm portion 50 are integrally formed, the plate-like base 10 is formed by a drawing process, and the thickness of the plate-like base 10 ranges from 0.8 mm to 1.0 mm.

[0027] The utility model provides a multi-contact spring sheet, which provides a contactable plane for the multi-contact spring sheet by setting the plate-like base 10, so as to facilitate the installation and assembly of the multi-contact spring sheet, and sets a first extension part 20 formed by bending downward and extending from the side of the plate-like base 10, a second extension part 30 formed by bending vertically and extending from the top of the first extension part 20, a first contact arm part 40 formed by bending downward and extending from one side of the second extension part 30, and a second contact arm part 50 formed by bending downward and extending from the other side of the second extension part 30, and sets multiple contact arm parts on a single spring sheet, so as to ensure that the overall size of the spring sheet does not increase, and the first and second contact arm parts 50 respectively and independently play the role of connection and conduction. When a problem occurs in a contact arm part, the other contact arm part can realize the performance of the spring sheet completely unaffected, and it occupies a small space, is stable and reliable, and meets customer needs.

[0028] As a further improvement of the present invention, the first contact arm portion 40 and the second contact arm portion 50 have the same extension length, and the first contact arm portion 40 and the second contact arm portion 50 both include at least one contact arm. By setting the first contact arm portion 40 and the second contact arm portion 50 to have the same extension length, the multi-contact spring sheet can be better placed on the welding plate during welding, ensuring the connection stability of the multi-contact spring sheet. In this embodiment, the extension lengths of the first contact arm portion 40 and the second contact arm portion 50 are less than the thickness of the plate-like base 10, further improving the reliability of the multi-contact spring sheet. By setting the first contact arm portion 40 and the second contact arm portion 50 to both include at least one contact arm, the connection contacts of the multi-contact spring sheet can be further increased, thereby increasing the number of components to be turned on and expanding the application range of the multi-contact spring sheet.

[0029] As a further improvement of the present invention, the second extension portion 30 is arranged in parallel with the plate-like base 10, the first contact arm portion 40 is arranged in parallel with the first extension portion 20 on one side, and the second contact arm portion 50 is arranged in parallel with the first extension portion 20 on one side. In this embodiment, the shape of the plate-like base 10 can be an irregular polygon such as a rectangle or a triangle, and the present application does not limit this. Preferably, the plate-like base 10 is a rectangle, and the first extension portion 20 is formed by bending downward and extending from the adjacent two side edges of the plate-like base 10. By arranging the second extension portion 30 in parallel with the plate-like base 10, the first contact arm portion 40 and The first extension portion 20 on one side is parallel, and the second contact arm portion 50 is parallel to the first extension portion 20 on the one side. While ensuring that the overall volume remains unchanged, the extension size of the first contact arm portion 40 and the second contact arm portion 50 is reduced, and the arrangement of the first extension portion 20 and the second extension portion 30 plays a role in relieving stress when the multi-contact spring is squeezed by external force, thereby improving the connection stability of the first contact arm portion 40 and the second contact arm portion 50, avoiding shaking under the action of external force, resulting in unstable connection between the first contact arm portion 40 and the second contact arm portion 50 and the welding class, thereby improving the stability of the multi-contact spring.

[0030] As a further improvement of the present invention, the multi-contact spring sheet further includes a third contact arm portion 60 extending outwardly from between the two sides of the second extension portion 30, the third contact arm portion 60 is arranged in parallel with the plate-like base portion 10, and the third contact arm portion 60 includes at least one contact arm. By extending outwardly between the two sides of the second extension portion 30 to form the third contact arm portion 60, the third contact arm portion 60 is arranged in parallel with the plate-like base portion 10, a contact arm portion for planar contact is provided for the multi-contact spring sheet, and the connection range of the multi-contact spring sheet is increased. By arranging the third contact arm portion 60 to include at least one contact arm, the connection contacts of the multi-contact spring sheet can be further increased, so as to increase the number of components to be turned on and to expand the applicable range of the multi-contact spring sheet.

[0031] As a further improvement of the present invention, the multi-contact spring sheet also includes a third contact arm portion 60 formed by bending downward and extending between the two sides of the second extension portion 30, the extension direction of the third contact arm portion 60 is the same as the extension direction of the first extension portion 20, and the third contact arm portion 60 includes at least one contact arm. By providing the third contact arm portion 60 extending outward between the two sides of the second extension portion 30, the extension direction of the third contact arm portion 60 is the same as the extension direction of the first extension portion 20, the number of contact arm portions of the multi-contact spring sheet is increased, and the connection range of the multi-contact spring sheet is improved. By providing the third contact arm portion 60 including at least one contact arm, the connection contacts of the multi-contact spring sheet can be further increased, so as to increase the number of components to be turned on, and further expand the application range of the multi-contact spring sheet.

[0032] As a further improvement of the present invention, see Figure 2 , the ends of the first contact arm portion 40 and the second contact arm portion 50 are both provided with an inwardly inclined inclined portion 71, and the plate-like base portion 10, the first extension portion 20, the second extension portion 30, the first contact arm portion 40 and the second contact arm portion 50 are all provided with arc chamfers. The inclined portion 71 is that the side surfaces of the ends are all inclined inwardly. By providing the inwardly inclined inclined portion 71 at the ends of the first contact arm portion 40 and the second contact arm portion 50, it is ensured that the multi-contact spring is better welded at the welding spot when it is welded to the welding plate, and the connection reliability of the multi-contact spring is ensured. By providing the plate-like base portion 10, the first extension portion 20, the second extension portion 30, the first contact arm portion 40 and the second contact arm portion 50 with arc chamfers, it is ensured that the multi-contact spring will not scratch other parts during installation, thereby improving the safety factor during installation and improving the reliability of the multi-contact spring.
