[0011] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] like Figures 1-2As shown, an auxiliary power line welding fixture includes a battery module 100 and a nickel sheet 200, and the nickel sheet 200 is installed at the end of the battery module 100, and also includes a fixture body 1 and a copper sheet 2, the nickel sheet 200 is provided with a bending portion 201, the bending portion 201 is fitted with the side of the battery module 100, and the side of the battery module 100 corresponding to the bending portion 201 has a groove 101, the fixture body 1 includes a main body 11, a clamping portion 12 and a crimping portion 13, the clamping portion 12 and the crimping portion 13 are installed side by side at one end of the main body 11, and there is a gap between the clamping portion 12 and the crimping portion 13, the clamping portion 12 is clamped in the groove 101, and the bending portion 201 is fitted with one end of the copper sheet 2 and clamped in the gap between the clamping portion 12 and the crimping portion 13. Specifically, in this embodiment, the battery module 100 is a cylindrical battery module, and several battery cells are connected in parallel through the nickel sheet 200. The bent portion 201 of the nickel sheet 200 is in contact with the side of the battery module 201. A groove 101 is reserved on the side of the battery module 100, and the groove 101 is a semicircular hole. Therefore, the clamping portion 12 of the clamp body 1 we designed is semi-cylindrical, and the crimping portion 13 is arranged on it, and a gap space is reserved between the two for the bent portion 201 and the copper sheet 2. During use, the operator holds the main body 11 and inserts it from the side groove 101 of the battery module 100, and the bent portion 201 can be embedded in the gap. Then the operator pushes the copper sheet 2 into the gap along the bent portion 201, and then uses the clamping portion 12 to cooperate with the crimping portion 13 to make the bent portion 201 of the nickel sheet 200 close to the copper sheet, thereby avoiding manual leveling, which leads to inconvenient production operations and easily causes problems of welding deviation and welding through. In addition, this clamp is compatible with a variety of types, which facilitates the welding of various types of modules, reduces product damage caused by manual operation, and can effectively prevent module welding quality risks.

[0015] like Figure 2 As shown, the main body 11 is provided with a finger position 111 to facilitate the operator to disassemble and assemble the clamp body 1.

[0016] like Figure 2 As shown, the other end of the copper sheet 2 is provided with a wiring tube 21 for convenient connection of the power line.

[0017] like Figure 2 As shown, the crimping portion 13 is further provided with a spring steel ball 131, the movable end of which contacts the end surface of the copper sheet 2. Specifically, when the side of the copper sheet 2 is inserted, it is squeezed by the spring steel ball 131, and the copper sheet 2 is fitted with the bent portion 201 of the nickel sheet 200, thus avoiding damage to the product due to loose contact during welding.

[0018] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
