[0027] In order to more clearly illustrate the embodiments of the utility model and the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0028] The utility model embodiment provides a CCS component and a battery pack, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , mainly including the wire sinking 1, the blister board 2, the sampling aluminum bar 3, the collection wire harness 4, and the wire fixing part 5.

[0029] In the first aspect, an embodiment of the utility model provides a CCS component, which includes a blister plate 2, on which a wire sink 1 is provided, and on both sides of the wire sink 1 are provided sampling aluminum bars 3, which are fixedly connected to the blister plate 2, and at the end of the blister plate 2 are provided a collection harness 4, which extends in the wire sink 1 and is electrically connected to the sampling aluminum bar 3 in the wire sink 1, and on both sides of the wire sink 1 are provided wire fixing parts 5, which fix the collection harness 4 to both sides of the wire sink 1.

[0030] Compared with the prior art, the wire harness is arranged on the CCS bracket, and other devices are required to fix the wire harness, which increases the overall height of the CCS assembly. In the present application, a wire sink 1 is arranged on the blister plate 2, and then the collection wire harness 4 and the wire fixing member 5 are arranged in the wire sink 1, so as to reduce the overall height of the CCS assembly, thereby reducing the occupied space of the CCS assembly.

[0031] Specifically, the blister plate 2 is made of PC material (i.e., polycarbonate), and has a height (in the embodiment, the height direction is Figure 5 The vertical direction is 5mm, and the height of the line sinking 1 is 1.5mm.

[0032] In one embodiment, the collection harness 4 includes a harness assembly 41 and a branching block 42. The branching block 42 is provided with a branching slot 43. After the harness assembly 41 passes through the branching slot 43, the branching slot 43 divides the harness assembly 41 into a first harness and a second harness (such as Figure 6 As shown, Figure 6The oblique lines in the middle represent the wire harnesses), the first wire harness and the second wire harness are arranged on different sides of the wire sink 1 and fixed by the wire fixing member 5. The wire harness assembly 41 is divided into two wire harnesses, which are fixed on both sides of the wire sink 1, respectively, which shortens the wire diameter of the wire harness on the blister board 2, and the wire harnesses on both sides do not cross, which improves the convenience of the arrangement and arrangement of the wire harnesses.

[0033] In one possible implementation, wire grooves 6 are provided on both sides of the wire sink 1, and the collection wire harness 4 is embedded in the wire grooves 6. The wire grooves 6 limit the collection wire harness 4 and prevent the wire harness from shaking on the wire sink 1.

[0034] Furthermore, a first tie hole 7 and a second tie hole 8 are provided on both sides of the wire trough 6 , and the wire fixing member 5 includes a tie. After the tie passes through the first tie hole 7 and the second tie hole 8 in sequence, the collection wire harness 4 is bundled in the wire trough 6 .

[0035] It is foreseeable that when the cable tie is used to fix the collection harness 4, the surface of the cable tie and the collection harness 4 may move relative to each other, thereby rubbing the surface of the collection harness 4 and damaging the surface of the collection harness 4. In order to ensure the integrity of the surface of the collection harness 4, a wear-resistant block 9 is provided between the wire groove 6 and the first cable tie hole 7, and the wear-resistant block 9 is fixed on the wire sink 1.

[0036] Preferably, the height of the wear-resistant block 9 is equal to the height difference between the upper surface of the blister plate 2 and the upper surface of the wire sink 1, so that the upper surface of the wear-resistant block 9 is flush with the upper surface of the blister plate 2.

[0037] In one possible implementation, an identification block 10 is provided in the wire sink 1, and the identification block 10 is used to display the CCS component identification for easy use. Specifically, the identification block 10 can be a positive and negative electrode identification, a voltage and temperature sampling identification, or other identifications. The identification block 10 can be fixed on the wire sink 1 by pasting, or by being formed on the surface of the wire sink 1 at the time of forming the wire sink 1, or by other methods.

[0038] In one possible implementation, a fixing groove 21 is provided on the blister plate 2, and the sampling aluminum bar 3 is embedded in the fixing groove 21. A connecting groove 22 is provided on the side of the fixing groove 21 close to the wire sink 1. The connecting groove 22 is used to connect the wire sink 1 and the fixing groove 21. After the collection harness 4 passes through the connecting groove 22 in the wire sink 1, it is electrically connected to the sampling aluminum bar 3 in the fixing groove 21.

[0039] It should be noted that the sampling aluminum bar 3 includes an output pole aluminum bar and a series aluminum bar. The output pole aluminum bar is respectively arranged at both ends of the blister plate 2 and located on different sides of the line sink 1. The series aluminum bar is arranged in a straight line on both sides of the line sink 1. The series aluminum bar is fixed to the blister plate 2 through two hot riveting points, and the output pole aluminum bar is fixed to the blister plate 2 through three hot riveting points.

[0040] Furthermore, the edge of the connection groove 22 is rounded to prevent the edge of the connection groove 22 from scratching the surface of the collection harness 4.

[0041] In a second aspect, an embodiment of the utility model provides a battery pack, which includes the above-mentioned CCS component and a battery module, and the battery module is electrically connected to the sampling aluminum bar 3.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device comprising the elements.
