Embodiment Construction
[0036] In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left, right" usually refer to the orientations shown in the drawings and the orientations in practical applications, "inner, lower, left, right" "Outside" refers to the inside and outside of the outline of the part.
[0037] The present invention provides a battery sealing cover assembly. The battery sealing cover assembly 1 includes a sealing cover plate 10 and a pole 11 mounted on the sealing cover 10. The battery sealing cover assembly 1 also includes an anti-rotation structure capable of preventing the pole 11 from rotating. 12. For example: the anti-rotation structure 12 can prevent the rotation of the pole 11 when it is subjected to a screwing force; The snap sleeve 120, combined with image 3 , 4 and Figure 8 As shown in , the upper opening of the stopper 120 is a first opening 121 , the lower end of the stopper 120 is a second opening 122 , and the...

The invention relates to the field of batteries, and discloses a battery sealing cover assembly, a battery and a battery pack. The battery sealing cover assembly (1) comprises a sealing cover plate (10) and a pole column (11) arranged on the sealing cover plate. The battery sealing cover assembly further comprises an anti-rotation structure (12) capable of preventing the pole column from rotating,the anti-rotation structure comprises a stop sleeve (120) which is fixed to the sealing cover plate, a first opening (121) and a second opening (122) are formed in the two ends of the stop sleeve respectively, and the stop sleeve is arranged outside the pole column in a sleeving mode. The battery sealing cover assembly is provided with the anti-rotation structure, so that the pole column is not liable to rotate, and the sealing performance of the battery sealing cover assembly is improved. The battery sealing cover assembly provided by the invention is applied to the battery, so that the sealing performance of the battery is improved. When a plurality of batteries provided by the invention are assembled into a battery, the sealing performance and the use safety of the battery pack are improved.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery sealing cover assembly, a battery and a battery pack. Background technique [0002] A battery refers to a cup, tank, or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate current. It is a device that can convert chemical energy into electrical energy. It has a positive pole and a negative pole. Generally speaking, a battery includes a casing and an electric core packaged in the casing, wherein the casing includes a box body and a sealing cover that covers the box body, and the pole of the battery is connected to the sealing cover through a hole provided on the sealing cover. [0003] In the existing external connection scheme of batteries, for example, in the process of connecting multiple batteries in series or in parallel to form a battery pack, the following methods can be used to connect multipl...
