The crown band includes an upper ring and a lower ring, with several spring strips forming a compression hole connecting the upper and lower rings. The crown band forms a closed cylindrical structure through a mating seam on its circumference. The shape of the mating seam includes a zigzag shape and / or an arc shape. The connector houses the crown band. This utility model has the following advantages: First, it changes the existing "C-shaped" open structure, making the entire crown band a "closed" open structure, and this opening refers to the mating seam, which is much smaller than the C-shaped opening in the prior art.

Description

Technical Field

[0001] This utility model relates to the field of electrical connector and electrical contact technology, and in particular to a crown strap and connector. Background Technology

[0002] like Figure 1 The crown shown is a common component in the electrical contact field of electrical connectors. It is generally made of copper, which has good elasticity, and is used to transmit current. For example... Figure 2 As shown, from the top view, the crown band has a "C-shaped" opening; as Figure 1 and Figure 3 As shown, that is, from the isometric view and the front view, its joint is a "straight line"; as Figure 4 As shown, the mating seam on the other side is not visible from the rear view. This crown band is widely used in the field of electrical contacts due to its ability to carry large currents and its low cost.

[0003] The production process of this crown band requires a flexible copper strip, which is formed through processes such as blanking, rolling, and electroplating. After rolling, multiple (sometimes thousands) crown bands are freely stacked in a container. Due to the "C-shaped" notch and the "straight" seam, two or more crown bands are easily nested together, commonly known as "clumping together." Figure 5 As shown. In extreme cases, all the crown bands may be nested within each other, forming a large clump. The disadvantages are: first, the nesting makes them prone to deformation; second, when electroplating gold or silver, the folded and covered areas are difficult for the electrolyte to penetrate, resulting in unplated spots on the crown band after electroplating, forming "black spots"; third, when using the crown band in subsequent processes, it needs to be peeled off one by one, wasting a lot of working time.

[0004] Therefore, how to prevent the crown from clumping together, thereby improving electroplating quality and assembly efficiency, is a technical problem that urgently needs to be solved.

[0005] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] In view of the shortcomings in the above-mentioned background technology, this utility model proposes a crown strap and connector, and the technical problem to be solved is: how to avoid crown strap clumping.

[0007] The technical solution of this utility model is as follows: A crown band includes an upper ring and a lower ring, with a plurality of spring strips forming a compression hole connecting the upper and lower rings. The crown band forms a closed cylindrical structure through mating seams on its circumferential surface. The shape of the mating seams includes a zigzag shape and / or an arc shape. This crown band features at least two unique characteristics. First, it changes the existing "C-shaped" open structure, making the entire crown band a "closed" open structure, where the opening refers to the mating seam, and this seam gap is much smaller than the C-shaped opening in the prior art. Second, the mating seam has a special shape, changing the straight seam in the prior art to a zigzag, arc, or a combination of zigzag and arc shapes, so that the projection of the crown band along its axial direction forms a closed "circle". Therefore, the crown bands do not nest with each other through the mating seams, nor do they clump together, thus avoiding the various drawbacks caused by nesting or clumping, such as deformation, incomplete electroplating, and the need for individual peeling operations.

[0008] Based on the above technical solutions, as a preferred technical solution for the crown band, the polygonal shape includes at least two intersecting line segments. This technical solution defines the preferred structure of the polygonal shape, namely, it includes at least two intersecting line segments. It should be noted that the line segments in this technical solution include both straight and curved line segments, and its core purpose is to make the mating seam a non-linear gap.

[0009] Based on the above technical solutions, as a preferred technical solution for the crown band, each included angle of the zigzag shape is a rounded obtuse angle. This technical solution further defines the structure of the mating joint, forming a smooth structure at the corners of the mating joint, avoiding the formation of sharp points, which can both evenly distribute internal stress and prevent sharp point discharge phenomena.

[0010] Based on the above technical solution, as a preferred technical solution for the crown band, the mating seam includes mating seam one between the two ends of the upper ring, mating seam two between the two ends of the lower ring, and mating seam three at the position corresponding to the spring strip. This technical solution further defines the composition of the mating seam, that is, the continuous mating seam is composed of gaps between different structures. Both the upper and lower rings are non-closed ring structures, and the two ends of the upper and lower rings respectively form the components of the mating seam, namely mating seam one and mating seam two; the position of the spring strip between the upper and lower rings forms mating seam three, which connects mating seam one and mating seam two.

[0011] Based on the above technical solution, as a preferred technical solution for the crown band, the third joint includes a straight seam located in the middle, with oblique seam one and oblique seam two connecting the first and second joints, respectively. This embodiment provides a preferred implementation of the first, second, and third joints, namely, a combination of oblique seam one and oblique seam two at the ends of the straight seam, which facilitates both stamping and butt joint forming, while also creating a non-linear butt joint with a better shape.

[0012] Based on the above technical solutions, as a preferred technical solution for the crown band, the first oblique slit and the second oblique slit are symmetrical about the mid-section of the crown band. This embodiment further defines the relative relationship between the straight slit, the first oblique slit, and the second oblique slit, further improving the convenience of stamping and butt joint forming, and also providing a better mating seam to avoid the crown band from nesting or clumping together.

[0013] Based on the above technical solutions, as a preferred technical solution for the crown band, the shape of the mating suture is a planar polygonal shape, a planar arc shape, a spatial polygonal shape, or a spatial arc shape. This embodiment further defines the shape of the mating suture, and also illustrates that the mating suture in the above embodiments is not limited to a planar shape, but can also be a spatial shape.

[0014] Based on the above technical solution, as a preferred technical solution for the crown band, the left end of the upper ring and the left end of the lower ring are connected by a left end plate, and the right end of the upper ring and the right end of the lower ring are connected by a right end plate, with the mating seam located between the left end plate and the right end plate.

[0015] Based on the above technical solution, as a preferred technical solution for the crown band, the upper ring, lower ring, and spring strip are an integral structure formed by stamping a whole copper sheet. Each spring strip includes a vertical section in the middle, and inclined section one and inclined section two located at both ends of the vertical section and respectively connected to the upper ring and lower ring. Inclined section one and inclined section two are symmetrical about the vertical section.

[0016] A connector includes a housing, within which a crown band as described in any of the above-mentioned technical solutions is disposed.

[0017] Compared with existing technologies, this invention not only provides a novel crown band and connector, but also a novel radio frequency (RF) pin component. The core of this invention lies in two aspects: First, it changes the existing "C-shaped" opening structure, making the entire crown band a "closed" opening, where the opening refers to the mating seam, and this gap is much smaller than the C-shaped opening in existing technologies. Second, the mating seam has a special shape, changing the straight seam in existing technologies to a zigzag, arc, or a combination of zigzag and arc shapes. Therefore, the crown bands will not nest together through the mating seam, nor will they clump together, thus avoiding the various drawbacks caused by nesting or clumping, such as deformation, incomplete electroplating, and the need for individual peeling operations.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] As described in the background section, existing crown bands have the following drawbacks: 1) they are prone to clumping and deformation; 2) when electroplating gold or silver, there are often localized areas without plating; 3) assembly requires manual separation of each piece, wasting time and increasing costs. Therefore, the purpose of this invention is to: 1) prevent clumping and deformation; 2) solve the problem of localized areas without plating when electroplating gold or silver; 3) eliminate the need for manual separation during assembly, saving time and reducing costs.

[0029] The specific implementation method is as follows: A crown band, such as Figures 6 to 10 As shown, the crown band includes an upper ring 1 and a lower ring 2. A plurality of spring strips 3 forming a constriction hole 4 connect the upper ring 1 and the lower ring 2. The constriction hole 4 is similar to existing technology, being a variable-diameter hole with a constriction section. Preferably, this feature is similar to the manufacturing process of existing technology, i.e., the crown band is made of copper material with good elasticity through stamping / cutting. The crown band forms a closed cylindrical structure through mating seams 5 on its circumferential surface. The shape of the mating seams 5 includes a zigzag shape and / or an arc shape.

[0030] The material and application used in this embodiment are the same as in the prior art, both being made of highly elastic copper for transmitting current. The difference lies in that, from a top view, the crown is a closed-type opening. From the left and right views, its mating seam is a zigzag line. This crown retains its ability to transmit large currents, has a lower cost, and can be widely used in the field of electrical contacts; furthermore, due to the advantages of its closed shape and zigzag mating seam, the crowns shown in this invention will not nest together or clump together.

[0031] The crown band in this embodiment includes at least two original features. First, it changes the existing "C-shaped" opening structure, making the entire crown band a "closed" opening, and this opening refers to the mating seam 5, which is much smaller than the C-shaped opening in the prior art. Second, the mating seam 5 has a special shape, changing the straight seam in the prior art to a zigzag, arc, or a combination of zigzag and arc shapes. Therefore, the crown bands will not nest with each other through the mating seam 5, nor will they clump together, thus avoiding the various drawbacks caused by nesting or clumping, such as deformation, incomplete electroplating, and the need for individual peeling operations.

[0032] Based on the above embodiments, as a preferred embodiment of the crown band, the zigzag shape includes at least two intersecting line segments.

This embodiment further defines the composition of the mating seam 5, that is, the continuous mating seam 5 is composed of gaps between different structures. The upper ring 1 and the lower ring 2 are both non-closed ring structures. The two ends of the upper ring 1 and the lower ring 2 respectively form the components of the mating seam 5, namely the first mating seam 51 and the second mating seam 52; the position of the spring strip 3 between the upper ring 1 and the lower ring 2 forms the third mating seam 53 connecting the first mating seam 51 and the second mating seam 52.

[0035] Based on the above embodiments, as a preferred embodiment of the crown band, the third seam 53 includes a straight seam 530 located in the middle, and the two ends of the straight seam 533 are oblique seam 1 531 and oblique seam 2 532 connecting the first seam 51 and the second seam 52, respectively. This embodiment provides a preferred implementation of the first seam 51, the second seam 52, and the third seam 53, that is, the combination of the straight seam 530 with oblique seam 1 531 and oblique seam 2 532 at both ends is convenient for stamping and butt forming, and at the same time forms a non-straight butt joint 5 with a better shape.

[0036] Based on the above embodiments, as a preferred embodiment of the crown band, the first oblique slit 531 and the second oblique slit 532 are symmetrical about the mid-section of the crown band. This embodiment further defines the relative relationship between the straight slit 530, the first oblique slit 531, and the second oblique slit 532, further improving the convenience of stamping and butt forming, and also providing a better mating seam 5 to avoid the crown band from nesting or clumping together.

[0037] Based on the above embodiments, as a preferred embodiment of the crown band, the shape of the mating seam 5 is a planar polygonal shape, a planar arc shape, a spatial polygonal shape, or a spatial arc shape. This embodiment further defines the shape of the mating seam 5, and also illustrates that the mating seam 5 in the above embodiments is not limited to a planar shape, but can also be a spatial shape.
