Description

Technical Field

[0001] This utility model relates to the field of spring structure technology, and more specifically, to a high-current plug-in spring. Background Technology

[0002] Existing reed structures (such as) Figure 1 As shown in the torsion spring diagram, within specific specifications and an effective cross-section, and considering the feasibility of the manufacturing process, the spring ribs must have a certain gap. This results in a limitation on the number of spring ribs, an inability to increase the effective contact area of ​​the spring, an inability to improve the current-carrying capacity of the spring, and an inability to improve the overall electrical performance of the spring. Specifically, this manifests as low current carrying capacity and high temperature rise. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-current plug-in spring that can have more ribs within a specific specification and effective cross-section, giving the spring a larger effective contact area, better current carrying capacity, and better electrical performance, thus breaking through the current bottleneck problems of spring current carrying capacity and temperature rise.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A high-current plug-in spring includes a first fixing strip and a second fixing strip, which are arranged opposite to each other. A plurality of first ribs and second ribs are respectively connected to the opposite sides of the first fixing strip and the second fixing strip, and the first ribs and second ribs are alternately distributed along the circumferential direction.

[0006] The first rib extends axially from one end of the first fixing band and is in a free state; the second rib extends axially from one end of the second fixing band and is in a free state.

[0007] The first and second reinforcing bars have at least one radially inwardly concave arc in the region of their axial extension sections.

[0008] As a further description of the above technical solution: both the first fixing belt and the second fixing belt are provided with openings, and the opening positions are the same.

[0009] As a further description of the above technical solution: the spring is rolled into a circle, and when unfolded, it is rectangular.

[0010] As a further description of the above technical solution: the first rib is integrally formed with the first fixing band, and the second rib is integrally formed with the second fixing band.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] The reed in this design has more ribs within a specific specification and effective cross-section, giving it a larger effective contact area, better current carrying capacity, and better electrical performance, thus overcoming the current bottlenecks in reed current carrying capacity and temperature rise.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 2-3 A high-current plug-in spring is described, wherein the plug-in spring is rolled into a circle and unfolds into a rectangle. The plug-in spring includes a first fixing band 1 and a second fixing band 2, which are arranged opposite to each other. Both the first fixing band 1 and the second fixing band 2 are provided with openings, and the openings are located at the same positions.

[0022] Multiple first ribs 3 and second ribs 4 are respectively connected to opposite sides of the first fixing band 1 and the second fixing band 2. The first ribs 3 and the second ribs 4 are alternately distributed along the circumferential direction. The first ribs 3 extend axially from one end of the first fixing band 1 in a free state. The second ribs 4 extend axially from one end of the second fixing band 2 in a free state. The first ribs 3 and the first fixing band 1 are integrally formed. The second ribs 3 and the second fixing band 1 are integrally formed.

[0023] In this embodiment, two sets of spring structures composed of fixing straps and reinforcing bars are designed, such as... Figure 4As shown, the ribs in the two sets of springs are inserted into each other into the gaps between the ribs, as shown. Figure 1 , 2 The first rib 3 and the second rib 4 fill the gap between each other, thereby overcoming the problems of the existing spring structure (torsion spring or crown spring, etc.) which are limited in the number of spring ribs due to gaps, cannot increase the effective contact area of ​​the spring, cannot improve the current carrying capacity of the spring, and cannot improve the overall electrical performance of the spring.

[0024] Example 2

[0025] Based on the above embodiments, the first rib 3 and the second rib 4 have at least one radially inwardly recessed arc in the region of their axially extending sections. For example... Figure 1 As shown, the first rib 3 and the second rib 4 are concave inward along the radial direction at a point at a specific distance in the axial direction, forming an arc. The first rib 3 and the second rib 4 are fitted together with a gap to form a mating spring with a one-dimensional contact point.

[0026] like Figure 2 As shown, two points at a specific axial distance of the first rib 3 are concave inward along the radial direction by a certain distance to form two arcs, and a point at a specific axial distance of the second rib 4 is concave inward along the radial direction by a certain distance to form one arc. The first rib 3 and the second rib 4 are fitted together with a gap to form a mating spring with three-dimensional contact points.

[0027] This embodiment designs one or more (two in this case) curved waist-retracting rib springs in interlocking combination to form interlocking springs with different performance and contact dimensions, ensuring effective contact area.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
