[0004] The utility model aims at providing a tinned photovoltaic welding band to overcome the above problems or at least partially solve the above problems.

[0005] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] The utility model provides a tinned photovoltaic welding band, including first tinned copper band and second tinned copper band, the first tinned copper band is sleeved with a plurality of second tinned copper bands, the inside of second tinned copper band is provided with cavity, first tinned copper band sets up in the cavity, still be provided with positioning convex and screw hole on second tinned copper band, the screw hole and positioning convex staggered setting, and the lower part of positioning convex enters the cavity, and with the upper surface of first tinned copper band contact.

[0007] As a further scheme of the utility model, the screw hole and the positioning convex are all provided with a plurality of the positioning convex and the screw hole are all provided on the second tinned copper band.

[0008] As a further scheme of the utility model, the lower part of the positioning convex is a hemispherical structure, and the lower part of the positioning convex is arranged in the cavity.

[0009] The utility model provides a tinned photovoltaic welding band, beneficial effect lies in: through the mode of combination assembly, realize the purpose of convenient dismounting, and also convenient for the tinned copper band and cell are fully welded fixed, thereby guarantee the stability of connection, its welding is convenient and simple, and use effect is good.

[0015] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0016] Referring to Figs. 1-3 The present application provides a tin-plated photovoltaic welding strip, which comprises a first tin-plated copper strip 1 and a second tin-plated copper strip 2. The first tin-plated copper strip 1 is sleeved with a plurality of second tin-plated copper strips 2. The second tin-plated copper strip 2 is internally provided with a cavity 5. The first tin-plated copper strip 1 is arranged on the cavity 5. The second tin-plated copper strip 2 is further provided with a positioning protrusion 3 and a threaded hole 4. The threaded hole 4 and the positioning protrusion 3 are arranged alternately. The lower part of the positioning protrusion 3 extends into the cavity 5 and is in contact with the upper surface of the first tin-plated copper strip 1.

[0017] The threaded hole 4 and the positioning protrusion 3 are both provided with a plurality of positioning protrusions 3 and threaded holes 4. The plurality of positioning protrusions 3 and threaded holes 4 are arranged on the second tin-plated copper strip 2. The first tin-plated copper strip 1 can be connected through the positioning protrusion 3. The second tin-plated copper strip 2 can also be connected with the first tin-plated copper strip 1 through the screw and the threaded hole 4.

[0018] The lower part of the positioning protrusion 3 is in a hemispherical structure and is arranged in the cavity 5. The contact between the first tin-plated copper strip 1 and the second tin-plated copper strip 2 can be ensured through the positioning protrusion 3.

[0019] In use, the second tin-plated copper strip 2 is aligned with the battery cells to be connected in series and then tin-plated and soldered to ensure the welding stability and connection stability between the second tin-plated copper strip 2 and the battery cells. Then, the first tin-plated copper strip 1 is passed through the cavities 5 on the multiple second tin-plated copper strips 2 in sequence, and the positioning protrusions 3 on the second tin-plated copper strip 2 are used to tighten and fix the first tin-plated copper strip 1. Then, an external bolt can be screwed into the threaded hole 4 and tightened and fixed with the first tin-plated copper strip 1, which achieves the purpose of convenient disassembly and assembly; or the second tin-plated copper strip 2 can be soldered to the first tin-plated copper strip 1 through the threaded hole 4, thereby ensuring the connection stability.

[0020] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
