[0048] The overall structure, working principle and technical effects of the connecting piece 100 and the battery 010 provided by the utility model are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0049] The connecting piece 100 and the battery 010 provided by the present invention are applied to a tablet battery 010 and a laptop battery 010, and can be applicable to a solution of assembling a dual battery cell 200 or a multi-battery cell 200 with a PCM (Power Control Module).

[0050] Please refer to Figure 1-Figure 8 The utility model provides a connecting sheet 100, comprising: a first body 110 and a second body 120; the second body 120 is connected to the first body 110 and can be bent relative to the first body 110.

[0051] It can be understood that by providing a second body 120 connected to the first body 110, the second body 120 can be bent relative to the first body 110. After the second body 120 is bent, the connecting piece 100 changes from a single layer to a double layer, and the thickness and strength of the connecting piece 100 are enhanced, thereby solving the problem of easy deformation of the connecting piece 100 during grinding, cleaning, transportation and assembly.

[0052] In this embodiment, please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 The connecting sheet 100 includes a first body 110. The first body 110 is a rectangular sheet structure, and the first body 110 includes a first side, a second side, a third side and a fourth side; the first side and the third side are arranged opposite to each other, and the second side and the fourth side are arranged opposite to each other.

[0053] In this embodiment, please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 The connecting sheet 100 includes a second body 120. The second body 120 is a rectangular sheet structure. Figure 2 , Figure 4 , Figure 6 and Figure 8 The second body 120 is connected to the first body 110 and can be bent relative to the first body 110.

[0054] The second body 120 and the first body 110 are sheet structures of the same shape and size, which can ensure the overall strength of the middle part of the double-layered connecting sheet 100.

[0055] In this embodiment, the second body 120 is bent relative to the first body 110 and forms a bending line 140. Figure 1 , Figure 3 , Figure 5 and Figure 7Two semicircular grooves 141 are provided at the connection between the second body 120 and the first body 110 . The two grooves 141 are provided along the bending line 140 and are respectively located at two ends of the bending line 140 .

[0056] It is understandable that the two grooves 141 are punched and formed together with the connecting piece 100 , and such a configuration facilitates the bending of the second body 120 .

[0057] Optionally, see Figure 1-Figure 6 , the second body 120 is connected to the first side of the first body 110. Then the first side of the first body 110 and the second body 120 form a bending line 140, and the second body 120 is bent along the first side of the first body 110 to form a double-layer design.

[0058] Optionally, the second body 120 may also be connected to the third side of the first body 110. Then the third side of the first body 110 and the second body 120 form a bending line 140, and the second body 120 is bent along the third side of the first body 110 to form a double-layer design.

[0059] Optionally, see Figure 7 and Figure 8 , the first side and the third side of the first body 110 can be connected to the second body 120. The first side and the third side of the first body 110 form a bending line 140 with the second body 120, and the two second bodies 120 are bent and overlapped along the first side and the third side of the first body 110 to form a three-layer design.

[0060] In this embodiment, the connecting sheet 100 includes a connecting portion 130 .

[0061] In this embodiment, please refer to Figure 1-Figure 8 The connection part 130 is relatively disposed at two ends of the first body 110. The connection part 130 is connected to the second side and the fourth side of the first body 110.

[0062] The length and width of the connection parts 130 at both ends of the first body 110 are selected according to the actual use of the connecting piece 100 and are not limited in this application.

[0063] Optionally, see Figure 4 and Figure 5 as well as Figure 7 and Figure 8, the two connecting parts 130 are arranged perpendicularly to the first body 110, that is, the two connecting parts 130 are arranged perpendicularly to the first side and / or the third side of the first body 110; the two connecting parts 130 are arranged in the same direction, so that the connecting piece 100 is U-shaped. For example, the two connecting parts 130 are arranged perpendicularly to the first body 110 and are both oriented in the direction of the first side of the first body 110. For example, the two connecting parts 130 are arranged perpendicularly to the first body 110 and are both oriented in the direction of the third side of the first body 110.

[0064] Optionally, see Figure 5 and Figure 6 , the two connecting parts 130 are arranged perpendicularly to the first body 110, that is, the two connecting parts 130 are arranged perpendicularly to the first side and / or the third side of the first body 110; the two connecting parts 130 are arranged in opposite directions, so that the connecting piece 100 is in a Z shape. For example, one of the connecting parts 130 is arranged perpendicularly to the first body 110 and faces the third side of the first body 110, and the other connecting part 130 is arranged perpendicularly to the first body 110 and faces the first side of the first body 110. For example, one of the connecting parts 130 is arranged perpendicularly to the first body 110 and faces the first side of the first body 110, and the other connecting part 130 is arranged perpendicularly to the first body 110 and faces the third side of the first body 110.

[0065] Optionally, see Figure 1 and Figure 2 , one of the connecting parts 130 is arranged perpendicularly to the first body 110, that is, one of the connecting parts 130 is arranged perpendicularly to the first side and / or the third side of the first body 110; the other connecting part 130 extends along one end of the first body 110. One of the connecting parts 130 is arranged to extend parallel to the second side direction or the fourth side direction of the first body 110; the other connecting part 130 is perpendicular to the first body 110 and faces the first side direction or the third side direction of the first body 110; so that the connecting piece 100 is in a 7-shape.

[0066] In this embodiment, please refer to Figure 1-Figure 8 The first body 110, the second body 120 and the connecting portion 130 in the connecting piece 100 are an integrally formed structure. The connecting piece 100 is formed by punching the composite strip through a punching device.

[0067] The adapter sheet can be stamped and formed by using a nickel sheet composite strip, a copper-nickel-plated composite strip or a copper-nickel composite strip.

[0068] It can be understood that, on the one hand, the existing connecting piece 100 is only provided with the first body 110 and the connecting portion 130, and the position of the second body 120 is the waste material that is punched out, which makes reasonable use of the waste material without increasing the material cost; on the other hand, the second body 120 is bent relative to the first body 110, so that the first body 110 changes from a single layer to a double layer, thereby enhancing the thickness and strength of the first body 110, that is, the thickness and strength of the middle position of the connecting piece 100. Through the above design, a bending process of the first body 110 is added to the traditional process, that is, the strength of the connecting piece 100 is increased, and the problem that the connecting piece 100 is easy to deform during the grinding, cleaning, transportation and assembly process is solved, while reducing the overall material cost.

[0069] Accordingly, please refer to Fig. 9 and Fig.10 The utility model provides a battery 010 including a connecting piece 100 .
