Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal conduction shrapnel, and particularly relates to a shrapnel with a large height. Background Art
[0002] In the application scenarios of using metal conduction shrapnel for electrical conduction, sometimes it is necessary to use shrapnel with a large height in some narrow and high installation environments. However, in some shrapnel with a large height, the simply supported arm is too short to reach the bottom (i.e., it cannot contact the welding part), which results in the shrapnel not being able to meet the application requirements of large elastic force. In other shrapnel with a large height, although the simply supported arm can reach the bottom, its length is too long, so that the provided elastic force is very limited. In short, the existing shrapnel with a large height has the problem that it cannot achieve a large elastic force. Content of the Utility Model
[0003] The technical problem solved by the utility model is to provide a shrapnel with a large height and a large elastic force.
[0004] To solve the above technical problem, the technical scheme adopted by the utility model is: a shrapnel with a large height, including a welding part, an elastic force arm, a simply supported arm, and a protection wall. The two sides of the welding part are respectively connected with the protection wall. A window is arranged on the protection wall, and the lower edge of the window forms a sliding contact area. The elastic force arm includes a first arc arm, a first force arm, a second arc arm, a second force arm, a third arc arm, an inclined force arm, and a contact force arm connected in sequence. One end of the first arc arm is connected to the welding part. The top end of the contact force arm protrudes above the top end of the protection wall. The contact force arm is connected to the simply supported arm. The two sides of the simply supported arm have abutting parts extending into the window. When the shrapnel with a large height is pressed, the abutting parts abut against the sliding contact area and can slide on the sliding contact area.
[0005] In one embodiment, the first force arm is perpendicular to the second force arm and the welding part.
[0006] In one embodiment, the welding part and the second force arm are on the same side of the first force arm.
[0007] In one embodiment, the top surface of the second force arm is a suction surface.
[0008] In one embodiment, the distance between the second force arm and the lower edge of the window in the height direction is 0.8 - 2 mm.
[0009] In one embodiment, the top surface of the second force arm is lower than the top surface of the protection wall.
[0010] In one embodiment, contact protrusions are arranged on the contact force arm.
[0011] In one embodiment, the bottom surface of the welding portion is the welding surface.
[0012] In one embodiment, the abutting portion is located at the bottom end of the simply supported force arm.
[0013] In one embodiment, the high-height elastic piece is an integrally formed one-piece structure.
[0014] The beneficial effects of the present utility model are as follows: The structure of the high-height elastic piece of the present utility model is simple and can well adapt to the installation environment with high and narrow space; the cooperation between the abutting portion on the simply supported force arm and the lower edge of the window enables the simply supported force arm to provide sufficient rebound force for the contact force arm while maintaining a small length, so that the high-height elastic piece can achieve a large elastic force to meet the application requirements; moreover, in actual application, when the abutting portion on the simply supported force arm contacts the lower edge of the window, it can contact and conduct with the two protection walls to form a path, thereby reducing the contact impedance and making the working contact of the high-height elastic piece more stable and reliable.

[0030] Embodiment 1
[0031] Please refer to Figures 1 to 3, Embodiment 1 of the present utility model is: A large-height elastic piece, including a welding part 1, an elastic force arm 2, a simply supported force arm 3, and a protection wall 4. On both sides of the welding part 1, there are respectively connected with the protection walls 4. On the protection wall 4, there is a window 41, and the lower edge of the window 41 forms a sliding contact area 42; the elastic force arm 2 includes a first arc arm 21, a first force arm 22, a second arc arm 23, a second force arm 24, a third arc arm 25, an inclined force arm 26, and a contact force arm 27 connected in sequence. One end of the first arc arm 21 far from the first force arm 22 is connected to one end of the welding part 1. The top end of the contact force arm 27 protrudes above the top end of the protection wall 4 to make contact conduction with an external device. One end of the contact force arm 27 far from the inclined force arm 26 is connected to the simply supported force arm 3. On both sides of the simply supported force arm 3, there are abutting parts 31 extending into the window 41; when the large-height elastic piece is pressed, the abutting parts 31 abut against the sliding contact area 42. When the pressure on the large-height elastic piece continues to increase, the abutting parts 31 slide on the sliding contact area 42 to achieve sliding contact with the sliding contact area 42. To reduce the frictional loss of the abutting parts 31 and extend the service life of the large-height elastic piece, preferably, the abutting parts 31 are arc-shaped.
[0032] In this embodiment, the abutting parts 31 are located at the bottom end of the simply supported force arm 3. In other embodiments, the abutting parts 31 can also be located in the middle section of the simply supported force arm 3, which can be specifically set according to actual needs.
[0033] The window 41 is rectangular. In other embodiments, the window 41 can also be of other shapes, such as waist-shaped, pentagonal, hexagonal, etc. Preferably, the sliding contact area 42 is arranged parallel to the welding part 1.
[0034] In this embodiment, the first force arm 22 is perpendicular to the second force arm 24 and the welding part 1, and the welding part 1 and the second force arm 24 are on the same side of the first force arm 22.
[0035] The bottom surface of the welding part 1 is a welding surface. As a preferred implementation method, the top surface of the second force arm 24 is a suction surface when implementing the surface mounting process. Therefore, when assembling this large-height elastic piece to other components, the surface mounting process can be used for assembly to improve the assembly efficiency.
[0036] To effectively protect the second force arm 24, the top surface of the second force arm 24 is arranged lower than the top surface of the protection wall 4.
[0037] The distance between the second force arm 24 and the lower edge of the window 41 in the height direction is 0.8 - 2 mm, which can ensure that the large-height elastic piece can provide a sufficient large elastic force.
[0038] The contact force arm 27 is provided with a contact protrusion 271. The existence of the contact protrusion 271 can improve the stability of the high-height elastic sheet in contact conduction with external devices. The contact protrusion 271 can be a convex structure formed by stamping.
[0039] As a preferred embodiment, the high-height elastic sheet of this embodiment is an integral structure integrally processed by processes such as cutting, bending, and stamping from a metal sheet.
[0040] In summary, the high-height elastic sheet provided by the present invention has a simple structure, can achieve a large elastic force to meet application requirements; when conducting under pressure, the contact impedance is low, and the working contact is more stable and reliable.
[0041] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
