[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] like Figure 1 and Figure 2 As shown, in the first aspect, an embodiment of the utility model provides a CCS assembly, which includes a bracket 10, an electrical connector and an avoidance portion 30. The electrical connector is arranged on the bracket 10, and the electrical connector includes a first electrical connector 21 and a plurality of second electrical connectors 22, and the plurality of second electrical connectors 22 are arranged at intervals along the second direction on the first side of the first electrical connector 21 and / or the second side of the first electrical connector 21, and the second electrical connector 22 is arranged at an angle to the first electrical connector 21, and the avoidance portion 30 is arranged on the bracket 10, and the avoidance portion 30 is aligned with at least part of the second electrical connector 22 along the third direction.

[0034] In the present application, the CCS assembly includes a plurality of electrical connections, and the plurality of electrical connections are spaced apart along a first direction.

[0035] By applying the technical solution of the utility model, an avoidance portion 30 is provided on the bracket 10. When the second electrical connector 22 is subjected to external force and generates displacement in the third direction, the avoidance portion 30 can accommodate part of the second electrical connector 22 to alleviate the external force exerted on the second electrical connector 22, thereby protecting the second electrical connector 22 and avoiding the risk of the second electrical connector 22 breaking, thereby protecting the structure of the first electrical connector 21 and the second electrical connector 22 and extending the service life of the device.

[0036] Wherein, X is the first direction, Y is the second direction, and Z is the third direction.

[0037] In the present application, the electrical connector is a flexible flat cable (FFC), which is made of two layers of insulating film with a flat copper foil sandwiched between them. The finished product is simpler and thicker. The number and spacing of wires in the flexible flat cable can be arbitrarily selected, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency.

[0038] Furthermore, the avoidance portion 30 is a avoidance hole, which is arranged along the third direction through the bracket 10, or the avoidance portion 30 is a slot structure. This arrangement not only facilitates the processing of the structure and reduces the processing difficulty of the structure, but also reduces the overall weight of the bracket 10, so as to achieve lightweight development of the bracket 10.

[0039] In the present application, the cross-section of the avoidance hole along the second direction is square. Of course, in other embodiments, the cross-section of the avoidance hole can also be set to other shapes such as trapezoidal, circular, etc., as long as it can play a buffering role for the first connecting portion 24.

[0040] Optionally, the avoidance portion 30 can also be set as a groove structure, as long as it can meet the avoidance requirements of the device. The specific setting should be selected according to the use environment of the device, which can improve the applicability and scope of application of the device.

[0041] Furthermore, the second electrical connector 22 is connected to the first electrical connector 21 via the first connecting portion 24 , and the avoiding portion 30 is aligned with the first connecting portion 24 along the third direction.

[0042] like Figure 4 and Figure 5 As shown, the projection of the avoidance portion 30 along the third direction covers the projection of the first connection portion 24 along the third direction. This arrangement can ensure that the avoidance portion 30 completely accommodates the first connection portion 24 to prevent the avoidance portion 30 from interfering with the first connection portion 24, thereby protecting the structure of the first connection portion 24 and improving the stability of the device when in use.

[0043] like Figure 3 As shown, the CCS assembly further includes a plurality of circuit boards 40, the circuit boards 40 are arranged in one-to-one correspondence with the first electrical connector 21, and are electrically connected to one end of the first electrical connector 21, two adjacent circuit boards 40 and the two electrical connectors form a group of connection components, and a second connection portion 41 is provided between two adjacent circuit boards 40 in each group of connection components. By providing the above structure, when two adjacent circuit boards 40 produce relative displacement, the second connection portion 41 can be used to absorb the deformation force between the two circuit boards 40, thereby reducing the displacement distance of the circuit boards 40, so as to ensure the normal operation of the circuit boards 40, thereby improving the stability of the device during operation.

[0044] Specifically, the extension length of the second connection portion 41 along the third direction is less than the extension length of the circuit board 40 along the third direction. This arrangement can prevent the second connection portion 41 from being too long, thereby preventing the connection strength of two adjacent circuit boards 40 from being too high, thereby preventing it from buffering the displacement of the circuit board 40. Therefore, through the above arrangement, the buffering requirements of the device can be met, and the weight of the device can also be reduced, so as to further achieve lightweight development of the device.

[0045] like Figure 6 As shown, further, the second connection portion 41 is provided with grooves 411 on both sides in the second direction. In the present application, the cross-sectional shape of the recessed portion is an arc, so that when the circuit board 40 is displaced along the first direction, the arc-shaped buffer structure can reduce the bending degree of the circuit board 40, thereby preventing the risk of the circuit board 40 being broken, and further improving the safety of the device when in use.

[0046] Optionally, in other embodiments of the present application, the shapes of the second connection portion 41 on both sides of the second direction can also be set to other structures such as protrusions, as long as the use requirements of the device can be met.

[0047] Specifically, the CCS assembly further includes a plurality of busbars 50, which are arranged on the bracket 10. The busbars 50 are arranged one-to-one with the second electrical connectors 22 and connected to the end of the second electrical connector 22 away from the first electrical connector 21. This arrangement enables the busbars 50 to be connected to the battery cells so that the FFC can collect them.

[0048] Furthermore, a nickel sheet 60 is provided between the second electrical connector 22 and the busbar 50, and the busbar 50 is welded to the second electrical connector 22 through the nickel sheet 60. After soldering, the welding point is then protected with UV glue to improve the connection strength between the two, so as to prevent the risk of the second electrical connector 22 and the busbar 50 falling off when the device is running, thereby ensuring the normal operation of the device.

[0049] Specifically, the CCS assembly further includes a sensor 70, and the electrical connector further includes a plurality of third electrical connectors 23, the plurality of third electrical connectors 23 are arranged at intervals along the second direction on the first side of the first electrical connector 21 and / or the second side of the first electrical connector 21, and the third electrical connector 23 and the second electrical connector 22 are arranged at intervals along the second direction, and the sensor 70 is connected to one end of the third electrical connector 23 away from the first electrical connector 21. In the present application, the sensor 70 is an NTC thermistor 70, so that the temperature of the battery can be detected to provide real-time temperature information to the user.

[0050] like Figure 7 As shown, the bracket 10 has a buffer portion 101. The buffer portion 101 of this embodiment is a slot structure. The buffer portion 101 has two side walls spaced apart along the second direction. The second electrical connector 22 is located in the buffer portion 101 and is spaced apart from the side walls. In this way, when the device expands, the buffer portion 101 can be used to provide horizontal movement space for the first electrical connector 21 and the second electrical connector 22 to prevent interference, thereby ensuring the normal operation of the device.

[0051] Furthermore, the bracket 10 is provided with an avoidance structure 102. The avoidance structure 102 of this embodiment is a slot structure, and the first electrical connector 21 and the second electrical connector 22 are arranged around the periphery of the avoidance structure 102. When the battery cell expands and pulls the first electrical connector 21 and the second electrical connector 22, the avoidance structure 102 can provide a movable space for the first electrical connector 21 and the second electrical connector 22 to prevent interference.

[0052] Specifically, the first electrical connector 21 is an FFC main line, and the second electrical connector 22 is an FFC branch line.

[0053] In a second aspect, an embodiment of the utility model provides a battery module, the battery module comprising: a battery cell; the above-mentioned CCS assembly, the CCS assembly being fixedly connected to the battery cell.

[0054] By applying the technical solution of the utility model, an avoidance portion 30 is provided on the bracket 10. When the first connection portion 24 between the first electrical connector 21 and the second electrical connector 22 is displaced in a third direction by an external force, the avoidance portion 30 can accommodate part of the first connection portion 24 to alleviate the external force exerted on the first connection portion 24, thereby protecting the first connection portion 24 and avoiding the risk of the first connection portion 24 breaking, thereby protecting the structure of the first electrical connector 21 and the second electrical connector 22 to extend the service life of the device.
