[0031] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0032] Reference will be made below to Figures 1 - 4 describe the sampling wire harness assembly 10 according to an embodiment of the present utility model. The sampling wire harness assembly 10 can be applied to the battery pack 100, and the battery pack 100 can be applied to an electrical device.

[0033] Combined with Figures 1 - 4 shown, the sampling wire harness assembly 10 according to the present utility model mainly includes: a sampling wire harness 11 and an anti-fooling limit member 12. Among them, connectors 111 are provided at both ends of the sampling wire harness 11. The two connectors 111 are respectively adapted to connect to the information output port 22 of one battery information collector 20 and the information input port 21 of another battery information collector 20. The sampling wire harnesses 11 are at least two. The anti-fooling limit member 12 is provided on at least part of the at least two sampling wire harnesses 11. The anti-fooling limit member 12 is located between the connectors 111 at both ends of the sampling wire harness 11 to fixedly connect at least part of the at least two sampling wire harnesses 11, so that the length of the part of each sampling wire harness 11 between the connector 111 and the anti-fooling limit member 12 is a fixed value.

[0034] Specifically, to adapt to the information collection and management of multiple battery cells in the battery pack 100, the battery information collector 20 can be used to collect the information of the battery cells and perform data exchange with the controller. It can not only transmit the collected information to the controller but also receive the control instructions from the controller. It should be noted that nickel plates 23 are provided on the battery information collector 20, and the nickel plates 23 are suitable for collecting the voltage data of the battery cells.

[0035] Among them, due to the high voltage platform and the large number of battery cell strings, multiple battery information collectors 20 need to be set for sampling. Multiple battery information collectors 20 form a multi-string battery information collector group 24. Each multi-string battery information collector group 24 is arranged at intervals. Each multi-string battery information collector group 24 contains at least two battery information collectors 20 arranged at intervals. An information input port 21 and an information output port 22 are provided on each battery information collector 20.

[0036] By providing a sampling wire harness 11 and respectively providing a plug-in connector 111 at both ends of the sampling wire harness 11, only by connecting the two plug-in connectors 111 to the information output port 22 of one battery information collector 20 and the information input port 21 of another battery information collector 20 respectively, the connection of two different battery information collectors 20 can be realized, so as to ensure the transmission of data in a string of battery information collection groups and ensure the normal progress of sampling.

[0037] Considering the cost issue, it is necessary to reuse the battery information collector 20 as much as possible, and the same type of connectors are also used for different battery information collector groups 24 as much as possible. Although this can effectively reduce the cost, it will cause some sampling wire harnesses 11 to be similar and there is a risk of incorrect insertion. For example, the sampling wire harness 11 in one string of battery information collector groups 24 is plugged and matched with another string of battery information collector groups 24, resulting in the interruption of information.

[0038] By arranging the anti-fooling limiting member 12 on at least part of at least two sampling wire harnesses 11, the anti-fooling limiting member 12 can fixedly connect at least part of at least two sampling wire harnesses 11, and make the plug-in connectors 111 at both ends of the sampling wire harness 11 be located outside both ends of the anti-fooling limiting member 12 respectively. Furthermore, it can play a role in fixing and limiting at least part of at least two sampling wire harnesses 11. Each sampling wire harness 11 has a part located between the plug-in connector 111 and the anti-fooling limiting member 12, and the length of the part of each sampling wire harness 11 located between the plug-in connector 111 and the anti-fooling limiting member 12 can be a fixed value.

[0039] It can be understood that when the length of the portion of each sampling wire harness 11 between the connector 111 and the anti-fooling limit member 12 is a fixed value, the movement range of the connectors 111 at both ends of each sampling wire harness 11 is limited. In this way, as long as the first installation point in the sampling wire harness assembly 10 is correct, and the subsequent installation points are installed in sequence, the correct assembly can be ensured, which has an anti-fooling effect. Different from the existing technology that simply uses process documents such as labels 114, it can effectively reduce the probability of wire harness installation errors, improve the speed and accuracy of assembly, and thus enhance the reliability of the battery pack 100. In addition, this can reduce the number of wire harnesses and lower the control cost.

[0040] It should be noted that the meaning of "a plurality of" is two or more. In some embodiments of the present invention, in combination with Figure 2 and Figure 3 as shown, the anti-fooling limit member 12 can fixedly connect at least a part of two sampling wire harnesses 11 at the same time. In other embodiments of the present invention, in combination with Figure 4 as shown, the anti-fooling limit member 12 can fixedly connect at least a part of more than two sampling wire harnesses 11 at the same time. According to the actual application scenario, the number of sampling wire harnesses fixedly connected by one anti-fooling limit member can be flexibly adjusted, and no specific limitation is made here.

[0041] Thus, by disposing the anti-fooling limit member 12 on at least a part of at least two sampling wire harnesses 11, the anti-fooling limit member 12 can fixedly connect at least a part of at least two sampling wire harnesses 11, so that the length of the portion of each sampling wire harness 11 between the connector 111 and the anti-fooling limit member 12 is a fixed value. In this way, the sampling wire harness assembly 10 can have an anti-fooling effect, can effectively reduce the probability of installation errors of the sampling wire harness 11, and enhance the reliability of the battery pack 100.

[0042] In combination with Figures 1 - 3 as shown, a temperature sampling sensor 112 is provided on the sampling wire harness 11. In this way, when the sampling wire harness 11 is applied to the battery pack 100, the temperature sampling sensor 112 on the sampling wire harness 11 can be attached to the surface of the battery cell, so that the temperature sampling sensor 112 can collect the temperature of the surface of the battery cell, or the temperature sampling sensor 112 on the sampling wire harness 11 can be attached to the connection copper bar between the battery cells, so that the temperature sampling sensor 112 can collect the temperature of the connection copper bar between the battery cells. Thus, it is convenient for the battery pack 100 to perform thermal management on the battery cells and enhance the reliability of the battery pack 100.

[0043] In combination with Figures 1 - 3As shown, the connectors 111 at both ends of the sampling wire harness 11 are the first connector 1111 and the second connector 1112 respectively. The first connector 1111 is adapted to be electrically connected to the information output port 22 of a battery information collector 20, and the second connector 1112 is adapted to be electrically connected to the information input port 21 of another battery information collector 20. The temperature sampling sensor 112 is electrically connected to the first connector 1111.

[0044] Specifically, the information output port 22 of the battery information collector 20 is also a temperature sampling port. By electrically connecting the temperature sampling sensor 112 to the first connector 1111, the data of the temperature sampling sensor 112 can also be transmitted between multiple battery information collectors 20 through the sampling wire harness 11 and finally transmitted to the controller for processing, so as to realize the thermal management of the battery cells.

[0045] Combined with Figures 2 - 4 As shown, the anti-misinsertion limiting member 12 is a limiting tape, and the limiting tape bundles and fixes at least part of at least two sampling wire harnesses 11. Specifically, the anti-misinsertion limiting member 12 can be set as a limiting tape. In this way, only by winding the limiting tape around at least part of multiple sampling wire harnesses 11, at least part of at least two sampling wire harnesses 11 can be bundled and fixed. This can not only make the realization of bundling and fixing at least part of at least two sampling wire harnesses 11 by the anti-misinsertion limiting member 12 simpler and more convenient, but also improve the reliability and stability of bundling and fixing at least part of at least two sampling wire harnesses 11 by the anti-misinsertion limiting member 12.

[0046] In addition, by setting the anti-misinsertion limiting member 12 as a limiting tape, the limiting tape is a flexible object. When the limiting tape is wound around at least part of at least two sampling wire harnesses 11, the limiting tape can fit with the outer periphery of at least part of at least two sampling wire harnesses 11. In this way, not only can the volume of the anti-misinsertion limiting member 12 be reduced, and the structural compactness of the sampling wire harness assembly 10 can be improved, but also when the anti-misinsertion limiting member 12 connects and fixes at least part of at least two sampling wire harnesses 11, damage to the sampling wire harness 11 can be avoided, wire skin breakage can be avoided, and the structural reliability of the sampling wire harness assembly 10 can be improved.

[0047] Furthermore, the limiting tape can include at least one of acetate tape, cloth-based tape and electrical tape. Specifically, acetate tape, cloth-based tape and electrical tape are all easy to tear and use, and have good adhesion and temperature resistance. By including at least one of acetate tape, cloth-based tape and electrical tape in the limiting tape, not only can it be further convenient for operators to use the limiting tape to bundle and fix at least part of at least two sampling wire harnesses 11, but also the reliability and stability of bundling and fixing at least part of at least two sampling wire harnesses 11 by the limiting tape can be improved, and the limiting tape can also withstand the heat of the battery cells to ensure the service life of the limiting tape.

[0048] It should be noted that in some other embodiments of the present utility model, the anti-fooling limiting member 12 can also be a plastic buckle. It is only necessary to place at least a part of at least two sampling wire harnesses 11 in the receiving cavity of the plastic buckle, and then fasten the plastic buckle, so that at least a part of at least two sampling wire harnesses 11 can be fixedly connected, which is convenient for the operator to operate and can make the realization of the fixed connection of at least a part of at least two sampling wire harnesses 11 by the anti-fooling limiting member 12 simpler and more reliable. Of course, the anti-fooling limiting member 12 can also be other fixing members, which are not specifically limited herein.

[0049] In some embodiments of the present utility model, the sampling wire harness 11 includes a fixing portion 113, and the fixing portion 113 extends in the length direction of the sampling wire harness 11. The limiting tape extends on the fixing portion 113 and bundles and fixes at least two sampling wire harnesses 11. Specifically, the fixing portion 113 is the part of the sampling wire harness 11 that needs to be fixed by the limiting tape. By making the limiting tape extend on the fixing portion 113, the limiting tape can completely wind around the outer periphery of the fixing portions 113 of multiple sampling wire harnesses 11, so that at least two sampling wire harnesses 11 can be bundled and fixed, and the stability and reliability of the bundling and fixing of at least two sampling wire harnesses 11 by the limiting tape can be improved.

[0050] In some other embodiments of the present utility model, the sampling wire harness 11 includes a fixing portion 113, and the fixing portion 113 extends in the length direction of the sampling wire harness 11. There are multiple limiting tapes, and at least two of the multiple limiting tapes are respectively arranged at both ends in the length direction of the fixing portion 113 to bundle and fix at least two sampling wire harnesses 11. Specifically, the fixing portion 113 is the part of the sampling wire harness 11 that needs to be fixed by the limiting tape. By setting the limiting tapes to be multiple and making at least two of the multiple limiting tapes be respectively arranged at both ends in the length direction of the fixing portion 113, the multiple limiting tapes can be fixed at both ends in the length direction of the fixing portion 113, so that not only can at least two sampling wire harnesses 11 be bundled and fixed, but also the amount of the limiting tape can be reduced and the material cost can be lowered.

[0051] Furthermore, one of the multiple limiting tapes is arranged in the middle in the length direction of the fixing portion 113. Specifically, after at least two of the multiple limiting tapes are respectively arranged at both ends in the length direction of the fixing portion 113, the fixing portion 113 may be scattered. By arranging one of the multiple limiting tapes in the middle in the length direction of the fixing portion 113, the limiting tape can bundle multiple sampling wire harnesses 11 together in the middle in the length direction of the fixing portion 113, so as to avoid the phenomenon of scattering of multiple wire harnesses and facilitate the operator to use the sampling wire harness assembly 10.

[0052] The battery pack 100 according to the present utility model may include: a battery assembly and the above-mentioned sampling wire harness assembly 10. Specifically, a plurality of battery cells form the battery assembly. By applying the sampling wire harness assembly 10 to the battery pack 100, the probability of wire harness assembly errors can be greatly reduced, and the assembly efficiency of the battery pack 100 can be improved.
