For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Reference is made below to Figure 1 - Figure 2 describe the sampling assembly 100 according to an embodiment of the present utility model.

[0029] As Figure 1 shown, the sampling assembly 100 according to an embodiment of the present utility model includes a sampling line row main body 1 and a sampling line row branch 2. The sampling line row main body 1 extends in a first direction and is used for welding with a plurality of conductive busbars. The sampling line row branch 2 extends in a second direction. One end of the FDC is welded to the sampling line row main body 1, and the other end is welded to the PCB board, wherein the first direction and the second direction are perpendicular to each other.

[0030] Referring to Figure 1 a specific example shown, the sampling line row main body 1 extends in the left-right direction, and the sampling line row branch 2 extends in the up-down direction. Here, the left-right direction and the up-down direction are only for the convenience of describing the present application, rather than a limitation to the present application. In this example, the sampling line row main body 1 and the sampling line row branch 2 are separately designed. Thus, the sampling line row main body 1 and the sampling line row branch 2 can be better designed and manufactured separately. Especially for the relatively complex sampling line row branch 2, even if the sampling line row main body 1 and the sampling line row branch 2 need to be welded after being separately designed and manufactured, but relative to the whole of the sampling assembly 100, it can reduce the design difficulty and manufacturing difficulty of the sampling assembly 100, thereby effectively reducing the cost of the sampling assembly 100.

[0031] Furthermore, referring to Figure 3 shown, in the up-down direction, the sampling line row branch 2 does not need to be integrally stamped on the sampling line row main body 1. Therefore, the size of the sampling line row main body 1 in the up-down direction can be better reduced. Or rather, when the sampling line row main body 1 is separately designed and manufactured, the width dimension of the sampling line row main body 1 is smaller. Therefore, more sampling line row main bodies 1 can be blanked on the same coil stock, and at the same time, the waste of winding can be reduced. Similarly, more sampling line row branches 2 can be better blanked on the same coil stock, and the effect of reducing the waste of the coil stock can also be achieved. Thus, the present utility model can also better reduce the cost.

[0032] Further, the sampling line row body 1 is connected with a plurality of legs 11. The legs 11 extend along the second direction, and the plurality of legs 11 are spaced apart along the first direction. The plurality of legs 11 are welded to the plurality of conductive busbars one by one. Refer to the appendix Figure 1 As shown, the legs 11 extend along the up and down direction, and the plurality of legs 11 are spaced apart along the left and right direction. By designing the legs 11 that extend along the up and down direction, the sampling line row body 1 can be better electrically connected to the conductive busbar.

[0033] Further, a plurality of first conductive lines are arranged on the sampling line row body 1. The plurality of first conductive lines correspond to the plurality of legs 11 one by one. One end of each first conductive line extends to the corresponding leg 11 respectively. Combining Figure 3 As shown, the other end of each first conductive line extends to the welding area 3 welded to the sampling line row branch 2. A plurality of second conductive lines are arranged on the sampling line row branch 2. The plurality of second conductive lines correspond to the plurality of first conductive lines one by one.

[0034] That is to say, the welding area 3 can be arranged on the sampling line row body 1. Thus, the other ends of the plurality of first conductive lines are integrated in the welding area 3, which can optimize the circuit layout of the sampling component 100. At the same time, the number of sampling line row branches 2 can also be reduced. That is, by arranging a plurality of second conductive lines on the sampling line row branch 2, the acquisition signals on the plurality of first conductive lines can be transmitted towards the PCB board, so as to better realize the signal transmission.

[0035] Therefore, for the sampling component 100 according to the embodiment of the present invention, by separately designing and manufacturing the sampling line row body 1 and the sampling line row branch 2, the structures of the sampling line row body 1 and the sampling line row branch 2 can be better designed, which can effectively reduce the production cost of the sampling component 100 as a whole. And more sampling line row bodies 1 and sampling line row branches 2 can be blanked out on the same coil material, so as to reduce the waste of the coil material, and further reduce the production cost of the sampling component 100. In addition, the plurality of first conductive lines on the sampling line row body 1 are all gathered in the welding area. When the sampling line row body 1 and the sampling line row branch 2 are welded, the plurality of second conductive lines correspond to the plurality of first conductive lines one by one, which can save the setting of connectors between the sampling line row body 1 and the sampling line row branch 2. And the welding method is simple and convenient, which can reduce the assembly cost of the sampling line row body 1 and the sampling line row branch 2.

[0036] In some embodiments of the present invention, a plurality of welding areas 3 are arranged. The number of the welding areas 3 is less than the number of the legs 11. A plurality of sampling line row branches 2 are arranged. The plurality of sampling line row branches 2 correspond to the plurality of welding areas 3 one by one. Four welding areas 3 are arranged. Refer to the appendix Figure 1As shown, there are four sampling line row branches 2. Thus, the circuit layout of the sampling component 100 can be better realized. At the same time, the sampling component 100 can also be better electrically connected to the PCB board.

[0037] Optionally, the dimensions of the multiple legs 11 in the up and down direction are the same. Optionally, bends can be provided on the legs 11 to adapt to the conductive busbars at different positions.

[0038] Optionally, as Figure 1 and Figure 3 shown, the multiple legs 11 are all located on one side of the sampling line row body 1 in the second direction. Thus, when blanking the sampling line row body 1, the coil material can be better utilized, improving the utilization rate of the coil material. At the same time, the shape of the sampling line row body 1 can also be simplified, reducing the production cost of the sampling line row body 1.

[0039] Optionally, as Figure 3 shown, the welding area 3 has multiple pads 31, and the multiple pads 31 correspond to the multiple first conductive lines one by one. Through the design of the pads 31, it is beneficial to the electrical connection between the first conductive line and the second conductive line. At the same time, the sampling line row branch 2 can also be better fixed on the sampling line row body 1 through the pads 31.

[0040] Furthermore, as Figure 3 shown, the multiple pads 31 are arranged in multiple rows in the second direction, and the pads 31 in adjacent rows are arranged in a staggered manner in the first direction. That is to say, there are multiple pads 31 arranged in the left and right direction, for example Figure 3 the two rows in, with multiple pads 31 arranged in each row. Through the layout of the pads 31, it is not only beneficial to the electrical connection between the second conductive line and the pads 31, but also can better make the sampling line row branch 2 fixed on the sampling line row body 1 through the pads 31.

[0041] Optionally, the sampling line row body 1 and the legs 11 are integrally formed by stamping. Thus, compared with the separate design and welded connection of the sampling line row body 1 and the legs 11, the sampling line row body 1 and the legs 11 being integrally formed by stamping can better reduce the welding cost of the sampling component 100, thereby optimizing the production cost of the sampling component 100.

[0042] In some embodiments of the present utility model, both the main body 1 of the sampling line row and the branch 2 of the sampling line row are flexible die-cut circuit boards. A flexible die-cut circuit board (FDC) is a highly reliable and extremely flexible circuit made of polyimide or polyester film through die-cutting technology. It can be freely bent, folded, and wound, and can move and stretch arbitrarily in three-dimensional space, enabling the sampling assembly 100 to be better arranged and electrically connected between the conductive bus bar and the PCB board. Additionally, through die-cutting processing, the process is environmentally friendly, with a short processing cycle and high efficiency, effectively saving the production and processing costs of the product.

[0043] Optionally, both the main body 1 of the sampling line row and the branch 2 of the sampling line row are flexible printed circuit boards (FPC).

[0044] In some embodiments of the present utility model, multiple legs 11 and the branch 2 of the sampling line row are both located on the same side of the main body 1 of the sampling line row in the second direction. For example, Figure 1 as shown, multiple legs 11 and the branch 2 of the sampling line row are both located on the upper side of the main body 1 of the sampling line row. Thus, the space of the sampling assembly 100 can be better arranged.

[0045] The present utility model also proposes a battery having the above embodiments.

[0046] For the battery according to the embodiments of the present utility model, by providing the sampling assembly 100 of the above embodiments, through the split design and manufacture of the main body 1 of the sampling line row and the branch 2 of the sampling line row, the structures of the main body 1 of the sampling line row and the branch 2 of the sampling line row can be better designed, effectively reducing the production cost of the sampling assembly 100 as a whole. Moreover, more main bodies 1 of the sampling line row and branches 2 of the sampling line row can be punched out on the same roll material, thereby reducing the waste of the roll material and further reducing the production cost of the sampling assembly 100. Thus, for the battery according to the embodiments of the present utility model, the production cost of the battery can be better reduced.
