[0045] The present application will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0046] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0047] The following combines Figure 1 and Figure 2 to describe the structure of a battery connector 1000 provided by the present application. The battery connector 1000 includes: a first connector 100 and a second connector 200. Among them, the first connector 100 is used to connect the positive electrode of the battery; the second connector 200 is used to connect the negative electrode of the battery.

[0048] Before describing the structures of the first connector 100 and the second connector 200, it should be noted that: since the shapes of the first connector 100 and the second connector 200 are the same, in order to save resources and at the same time avoid large-scale modification of the existing first connector 100 and second connector 200, wasting time. The present application can distinguish between the two on the basis of the existing structures of the first connector 100 and the second connector 200, so as to achieve the purpose of saving resources and improving production efficiency.

[0049] Therefore, as shown in Figure 1 and Figure 2 , in the present application, a first assembly portion 105 and a second assembly portion 205 are respectively provided on the first connector 100 and the second connector 200, and at least one of the setting positions and the setting shapes of the first assembly portion 105 and the second assembly portion 205 is set differently, so that a more intuitive distinction between the first connector 100 and the second connector 200 can be achieved.

[0050] Next, the structures of the first connector 100 and the second connector 200 will be described exemplarily respectively.

[0051] Continuing as shown in Figure 1 , the first connector 100 may be a cube or a cuboid structure. Then, the first connector 100 may include a plurality of side edges. For the convenience of subsequent description, the plurality of side edges may be defined as a first side edge 101, a second side edge 102, a third side edge 103, and a fourth side edge 104.

[0052] Among them, the first side edge 101 and the third side edge 103 may be opposite side edges arranged oppositely, and the second side edge 102 and the fourth side edge 104 may be opposite side edges arranged oppositely; in addition, the first side edge 101 and the third side edge 103 may be side edges arranged in the horizontal direction, and the second side edge 102 and the fourth side edge 104 may be side edges arranged in the vertical direction. The limitation here is only for the convenience of subsequent description and does not specifically limit the first connector 100.

[0053] Continuing as shown in Figure 2 , the second connector 200 may also be a cube or a cuboid structure. Here, it should be noted that since the structures of the first connector 100 and the second connector 200 are the same in the prior art, when the first connector 100 is a cube, the second connector 200 is also a cube, and when the first connector 100 is a cuboid, the second connector 200 is also a cuboid.

[0054] Similarly, the second connector 200 may also include a plurality of side edges. For the convenience of subsequent description, the plurality of side edges may be defined as a fifth side edge 201, a sixth side edge 202, a seventh side edge 203, and an eighth side edge 204.

[0055] Among them, the fifth side edge 201 and the seventh side edge 203 may be opposite side edges arranged oppositely, and the sixth side edge 202 and the eighth side edge 204 may be opposite side edges arranged oppositely; in addition, the fifth side edge 201 and the seventh side edge 203 may be side edges arranged in the horizontal direction, and the sixth side edge 202 and the eighth side edge 204 may be side edges arranged in the vertical direction. The limitation here is only for the convenience of subsequent description and does not specifically limit the second connector 200.

[0056] It can be understood that the first side 101 of the first connector 100 corresponds to the fifth side 201 of the second connector 200, the second side 102 of the first connector 100 corresponds to the fifth side 201 of the sixth connector, the third side 103 of the first connector 100 corresponds to the seventh side 203 of the second connector 200, and the fourth side 104 of the first connector 100 corresponds to the eighth side 204 of the second connector 200.

[0057] In order to distinguish the first connector 100 from the second connector 200, so that during the subsequent welding process of the first connector 100 and the second connector 200, they can be easily distinguished and not be taken wrongly, thereby avoiding problems such as the welding head sticking and the bottom film being damaged during welding, the present application respectively sets a first assembly portion 105 and a second assembly portion 205 on the first connector 100 and the second connector 200. Some possible embodiments of the setting positions and setting shapes of the first assembly portion 105 and the second assembly portion 205 will be exemplarily described below.

[0058] First, as Figure 3 shown, a first assembly portion 105 can be provided on the first side 101 of the first connector 100, and at the same time, a second assembly portion 205 can be provided on the sixth side 202 of the second connector 200.

[0059] It should be noted here that at this time, the shapes of the first assembly portion 105 and the second assembly portion 205 can be set to the same shape, and only the setting positions of the first assembly portion 105 and the second assembly portion 205 are set differently. Exemplarily, the first assembly portion 105 and the second assembly portion 205 are semi - circles. Since the shapes of the first assembly portion 105 and the second assembly portion 205 are the same, the same tool can be used to set the first assembly portion 105 and the second assembly portion 205, and there is no need to change tools midway, so the processing efficiency of the first connector 100 and the second connector 200 can be improved.

[0060] Second, continuing as Figure 1 and Figure 2 shown, a first assembly portion 105 can be provided at the mid - point position of the first side 101 of the first connector 100, and at the same time, a second assembly portion 205 can be provided at any position other than the mid - point on the fifth side 201 of the second connector 200.

[0061] It should be noted here that at this time, the shapes of the first assembly part 105 and the second assembly part 205 can also be set to the same shape, and only the first assembly part 105 and the second assembly part 205 are set at different positions in the first connecting member 100 and the second connecting member 200. Exemplarily, the first assembly part 105 and the second assembly part 205 are semi-circular. Since the first side 101 and the fifth side 201 are corresponding sides, when setting the first assembly part 105 and the second assembly part 205 with the same tool, not only is it unnecessary to replace the tool, but also when processing different connecting members, the moving displacement of the tool is small, so the processing efficiency of the first connecting member 100 and the second connecting member 200 can be further improved. Exemplarily, the second assembly part 205 can be set at one-third, one-fourth, one-fifth, etc. of the fifth side 201.

[0062] Thirdly, as Figure 4 shown, the first assembly part 105 and the second assembly part 205 can be set at other positions in the first connecting member 100 and the second connecting member 200 except the sides, and the cross-sectional shapes of the first assembly part 105 and the second assembly part 205 along the horizontal direction can be set to different shapes. For example, the first assembly part 105 is set to a flower shape, and the second assembly part 205 is set to a heart shape.

[0063] It should be noted here that the cross-sectional shapes of the first assembly part 105 and the second assembly part 205 along the horizontal direction can reflect the overall setting shapes of the first assembly part 105 and the second assembly part 205. When the cross-sectional shapes of the first assembly part 105 and the second assembly part 205 along the horizontal direction are set differently, it means that the set shapes of the first assembly part 105 and the second assembly part 205 are completely different, which makes the difference between the first assembly part 105 and the second assembly part 205 greater, strengthens the difference between the first connecting member 100 and the second connecting member 200, and then the first connecting member 100 and the second connecting member 200 are better distinguished.

[0064] Fourthly, as Figure 5 shown, the angle formed between the first side 101 and the second side 102 in the first connecting member 100 can be cut to obtain the first assembly part 105, and at the same time, the angle formed between the fifth side 201 and the eighth side 204 in the second connecting member 200 can be cut to obtain the second assembly part 205, so as to distinguish the first connecting member 100 and the second connecting member 200. This method of distinguishing the first connecting member 100 and the second connecting member 200 can be operated without a professional tool for etching shapes, is convenient and fast, and can improve the production efficiency of the first connecting member 100 and the second connecting member 200.

[0065] The above is only an exemplary description of the setting positions and shapes of the first assembly part 105 and the second assembly part 205. Of course, it is also possible to only set the first assembly part 105 on the first connecting part 100 and retain the original shape of the second connecting part 200; only set the second assembly part 205 on the second connecting part 200 and retain the original shape of the first connecting part 100. There are other different ways to distinguish the first connecting part 100 and the second connecting part 200, and the present application will not list them one by one here.

[0066] It can be understood that since the first connecting part 100 is used to connect to the positive electrode of the battery, the material of the first connecting part 100 can be copper-nickel. The second connecting part 200 can be used to connect to the negative electrode of the battery, so the material of the second connecting part 200 can be aluminum.

[0067] The first connecting part 100 and the second connecting part 200 in the present application are used to connect the battery. Specifically, the first connecting part 100 needs to fix the core ear of the battery through the first adhesive part provided thereon; similarly, the second connecting part 200 also needs to fix the core ear of the battery through the second adhesive part provided thereon.

[0068] As Figure 6 shown and Figure 7 shown, there is a first bonding area 106 provided on the first connecting part 100, and the first bonding area 106 is used to bond the first adhesive part; there is a second bonding area 206 provided on the second connecting part 200, and the second bonding area 206 is used to bond the second adhesive part.

[0069] Exemplarily, the first bonding area 106 can be surrounded by a part of the second side 102, a part of the fourth side 104 on the first connecting part 100, and the area between a part of the second side 102 and a part of the fourth side 104. Generally speaking, there is a first bonding area 106 provided at the waist of the first connecting part 100.

[0070] Exemplarily, the second bonding area 206 can be surrounded by a part of the sixth side 202, a part of the eighth side 204 on the second connecting part 200, and the area between a part of the sixth side 202 and a part of the eighth side 204. Generally speaking, there is a second bonding area 206 provided at the waist of the second connecting part 200.

[0071] It should be noted here that since the first connecting member 100 and the second connecting member 200 are relatively thin, the first connecting member 100 and the second connecting member 200 can also be regarded as square and rectangular structures. Therefore, the first connecting member 100 and the second connecting member 200 include two oppositely arranged surfaces. The setting of the first assembling portion 105 and the second assembling portion 205 can further distinguish the front and back surfaces of the first connecting member 100 and the second connecting member 200, avoiding being placed or taken wrongly.

[0072] Therefore, it can be understood that the first bonding area 106 and the second bonding area 206 exist on two oppositely arranged surfaces of the first connecting member 100 and the second connecting member 200.

[0073] Then the first adhesive can be formed by winding around the waist position of the first connecting member 100. Similarly, the second adhesive can be formed by winding around the waist position of the second connecting member 200.

[0074] In addition, since the first adhesive and the second adhesive are used to fix the cell tab, on the one hand, for the convenience of fixing the cell tab, and on the other hand, to isolate the cell tab from other areas of the first connecting member 100 except the first adhesive and the second adhesive, generally the first adhesive is extended beyond the second side 102 and / or the fourth side 104, and similarly, the second adhesive is extended beyond the sixth side 202 and / or the eighth side 204.

[0075] Exemplarily, the first adhesive extends beyond the second side 102 and the fourth side 104, the second adhesive extends beyond the sixth side 202 and the eighth side 204, and the lengths by which the first adhesive extends beyond the second side 102 and the fourth side 104 can be the same as the lengths by which the second adhesive extends beyond the sixth side 202 and the eighth side 204.

[0076] In order to strengthen the distinction between the first connecting member 100 and the second connecting member 200 in this application, in addition to setting the first assembling portion 105 and the second assembling portion 205 on the first connecting member 100 and the second connecting member 200, further distinction can also be made starting from the first adhesive and the second adhesive.

[0077] Exemplarily, the first adhesive extends beyond the second side 102, and the second adhesive extends beyond the eighth side 204.

[0078] Exemplarily, the first adhesive extends beyond the fourth side 104, and the second adhesive extends beyond the sixth side 202.

[0079] Exemplarily, the first adhesive member extends along the second side 102 and the fourth side 104, and the second adhesive member extends along the sixth side 202 and the eighth side 204. Moreover, the lengths of the first adhesive member extending along the second side 102 and the fourth side 104 can be different from the lengths of the second adhesive member extending along the sixth side 202 and the eighth side 204 respectively.

[0080] Exemplarily, as Figure 8 shown, a first identifier is provided on the first adhesive member, and no identifier or a second identifier is provided on the second adhesive member. The first identifier and the second identifier are, for example, patterns, letters, etc., and the first identifier and the second identifier are different.

[0081] The above only exemplarily lists different settings of the first adhesive member and the second adhesive member. There can be other setting methods for the first adhesive member and the second adhesive member, as long as there are differences.

[0082] In addition, also for differentiating the first connecting member 100 and the second connecting member 200, the first assembling portion 105 can be provided on the first adhesive member, and the second assembling portion 205 can be provided on a region of the second connecting member 200 other than the second bonding region 206;

[0083] Alternatively, the first assembling portion 105 can be provided on a region of the first connecting member 100 other than the first bonding region 106, and the second assembling portion 205 can be provided on the second adhesive member;

[0084] Or, both the first assembling portion 105 and the second assembling portion 205 are provided on the first adhesive member and the second adhesive member, but the first assembling portion 105 and the second assembling portion 205 are provided at different positions on the first adhesive member and the second adhesive member, or the shapes of the first assembling portion 105 and the second assembling portion 205 are set differently, etc., which are not listed here.

[0085] Through the above different settings of the positions and shapes of the first assembling portion 105, the second assembling portion 205, the first adhesive member and the second adhesive member, various different differentiating methods can be set for the first connecting member 100 and the second connecting member 200, so as to better differentiate the first connecting member 100 and the second connecting member 200 and avoid confusing the two.

[0086] In another embodiment of the present application, a tray is further provided, wherein the tray is used to store the first connecting member 100 or the second connecting member 200.

[0087] Of course, since the first connecting member 100 and the second connecting member 200 have different functions, they are separately stored when being stored. Since the structures of the first connecting member 100 and the second connecting member 200 in this application are different, correspondingly, the shapes of the tray for storing the first connecting member 100 and the tray for storing the second connecting member 200 must be different.

[0088] Here, for the convenience of description, the tray for storing the first connecting member 100 is referred to as the first tray 300, and the tray for storing the second connecting member 200 is referred to as the second tray 400.

[0089] Next, based on the structure of the first connecting member 100 above, an exemplary description of the structure of the first tray 300 is given:

[0090] As Figure 9 shown, the first tray 300 includes a first base 301, and the shape and size of the first base 301 can be set according to requirements and are not limited herein. Exemplarily, the first base 301 is a cuboid.

[0091] The material of the first base 301 can be materials such as bakelite and ABS. Selecting such materials can, on the one hand, prevent the first connecting member 100 placed from introducing metal chips, and on the other hand, make the produced tray lighter, facilitating operations such as feeding and handling.

[0092] Since the function of the first tray 300 is to store the first connecting member 100, setting the first base 301 as a solid structure cannot play the role of storage. Therefore, a first storage cavity 302 needs to be opened on the first base 301. The shape of the first storage cavity 302 matches the shape of the first connecting member 100. That is to say: if the first connecting member 100 is a rectangular structure, then the first storage cavity 302 is also a rectangular structure. However, the length and width of the size of the first storage cavity 302 need to be slightly larger than the length and width of the first connecting member 100, which facilitates the placement of the first connecting member 100 and storing more first connecting members 100 in one first storage cavity 302.

[0093] After the first storage cavity 302 is opened on the first base 301, the first storage cavity 302 will form a bottom surface and four side walls. For the convenience of description, the four side walls are respectively named: the first side wall 3011, the second side wall 3012, the third side wall 3013, and the fourth side wall 3014.

[0094] In addition, since the first fitting portion 105 is provided on the first connecting member 100, a first mating portion 3015 corresponding to the first fitting portion 105 is provided in the first receiving cavity 302. In this way, the first tray 300 and the second tray 400 for receiving the second connecting member 200 can be distinguished in terms of shape, avoiding the situation of misplacing the first connecting member 100 and the second connecting member 200. In this way, during use, overall distinction can also be better achieved.

[0095] Since there are various possible setting positions of the first fitting portion 105, there are also various possible setting positions and shapes of the first mating portion 3015.

[0096] Exemplarily, if the first fitting portion 105 is provided on the first side 101 of the first connecting member 100, then the first mating portion 3015 can also be provided on the first side wall 3011 of the first receiving cavity 302.

[0097] Exemplarily, if the first fitting portion 105 is provided at other positions of the first connecting member 100 except the side, then the first mating portion 3015 can be provided in the inner cavity of the first receiving cavity 302.

[0098] Exemplarily, if the shape of the first fitting portion 105 is flower-shaped, then the cross-section of the first mating portion 3015 along the horizontal direction of the first receiving cavity 302 is flower-shaped.

[0099] The first mating portion 3015 can also have other setting positions and shapes, which will not be listed one by one here. Its position and shape are restricted by the position and shape of the first fitting portion 105.

[0100] In another embodiment, the first end of the first mating portion 3015 is flush with the upper surface of the first receiving cavity 302 away from the first base 301, and the second end of the first mating portion 3015 is connected to the first base 301. Of course, the first mating portion 3015 and the first base 301 can be connecting members or integral parts, and the present application does not limit this.

[0101] In another alternative embodiment, the first end of the first mating portion 3015 can also be higher than the upper surface of the first base 301. Such a setting can avoid the situation that when the first connecting member 100 is received on the upper surface of the first base 301, the first connecting member 100 near the upper surface of the first base 301 is likely to come out.

[0102] On the other hand, since the first adhesive member 107 is provided on the first connecting member 100, the lengths of the first adhesive member 107 extending from the second side 102 and the fourth side 104 may be the same or different. Therefore, on the second side wall 3012 and the fourth side wall 3014 corresponding to the second side 102 and the fourth side 104 of the first connecting member 100 in the first receiving cavity 302, receiving grooves for accommodating the first adhesive member 107 extending out of the first connecting member 100 are respectively formed. Since the receiving grooves need to be formed on the second side wall 3012 and / or the fourth side wall 3014, for the convenience of description, the receiving groove formed on the second side wall 3012 is referred to as the first receiving groove 3016 herein, and the receiving groove formed on the fourth side wall 3014 is referred to as the second receiving groove 3017.

[0103] Exemplarily, if the lengths of the first adhesive member 107 extending out of the second side 102 and the fourth side 104 are the same, then the length of the first receiving groove 3016 extending out of the second side wall 3012 may be set to be the same as the length of the second receiving groove 3017 extending out of the fourth side wall 3014.

[0104] Exemplarily, if the lengths of the first adhesive member 107 extending out of the second side 102 and the fourth side 104 are different, then the length of the first receiving groove 3016 extending out of the second side wall 3012 may be set to be different from the length of the second receiving groove 3017 extending out of the fourth side wall 3014.

[0105] Exemplarily, if the length of the first adhesive member 107 extending out of the second side 102 is greater than the length of the first adhesive member 107 extending out of the fourth side 104, then the length of the first receiving groove 3016 extending out of the second side wall 3012 may be set to be greater than the length of the second receiving groove 3017 extending out of the fourth side wall 3014.

[0106] Of course, the shapes, sizes, etc. of the first receiving groove 3016 and the second receiving groove 3017 are restricted by the first adhesive member 107, and the specific structures of the first receiving groove 3016 and the second receiving groove 3017 are not limited herein.

[0107] In another alternative embodiment, a plurality of first receiving cavities 302 may be provided on the first base 301, and the shapes of the respective first receiving cavities 302 are the same. The respective first receiving cavities 302 may be arranged adjacent to each other. In this way, on the one hand, space can be saved and space waste can be avoided; on the other hand, a larger number of first receiving cavities 302 can be provided to accommodate more first connecting members 100.

[0108] In yet another alternative embodiment, a plurality of first material leakage holes 3018 may be provided at the bottom of each first storage cavity 302. The purpose of providing the first material leakage holes 3018 is to store foreign objects other than the first connector 100 and prevent these foreign objects from adhering to the first connector 100.

[0109] Next, the shape of the second tray 400 will be described in conjunction with Figure 10 :

[0110] It can be understood that the shape of the second tray 400 matches the shape of the second connector 200, and the shape of the second tray 400 changes according to the change in the shape of the second connector 200.

[0111] As Figure 10 shown, the second tray 400 includes a second base 401. The shape and size of the second base 401 can be set as required and are not limited herein. Exemplarily, the second base 401 is a cuboid.

[0112] The material of the second base 401 can be materials such as bakelite and ABS. Selecting such materials can, on the one hand, prevent the second connector 200 placed from introducing metal chips, and on the other hand, make the produced tray lighter, facilitating operations such as feeding and handling.

[0113] Since the function of the second tray 400 is to store the second connector 200, setting the second base 401 as a solid structure cannot play the role of storage. Therefore, a second storage cavity 402 needs to be opened on the second base 401. The shape of the second storage cavity 402 matches the shape of the second connector 200. That is to say: if the second connector 200 is a rectangular structure, then the second storage cavity 402 is also a rectangular structure. However, the length and width of the size of the second storage cavity 402 need to be slightly larger than the length and width of the second connector 200, which facilitates the placement of the second connector 200 and storing more second connectors 200 in one second storage cavity 402.

[0114] After the second storage cavity 402 is opened on the second base 401, the second storage cavity 402 will form a bottom surface and four side walls. For the convenience of description, the four side walls are distinguished from the four side walls of the first storage cavity 302 and are respectively named: the fifth side wall 4011, the sixth side wall 4012, the seventh side wall 4013, and the eighth side wall 4014.

[0115] In addition, since the second fitting portion 205 is provided on the second connecting member 200, a second mating portion 4015 corresponding to the second fitting portion 205 is provided in the second receiving cavity 402. In this way, the second tray 400 and the second tray 400 can be distinguished in terms of shape, avoiding the situation of misplacing the first connecting member 100 and the second connecting member 200. In this way, better overall distinction can also be made during use.

[0116] Since there are many different possible positions for the setting of the second fitting portion 205, there are also many different possible positions and shapes for the setting of the second mating portion 4015.

[0117] Exemplarily, if the second fitting portion 205 is provided on the fifth side 201 of the second connecting member 200, then the second mating portion 4015 can also be provided on the fifth side wall 4011 of the second receiving cavity 402.

[0118] Exemplarily, if the second fitting portion 205 is provided at other positions of the second connecting member 200 except the sides, then the second mating portion 4015 can be provided in the inner cavity of the second receiving cavity 402.

[0119] Exemplarily, if the shape of the second fitting portion 205 is a heart shape, then the cross-section of the second mating portion 4015 along the horizontal direction of the first receiving cavity 302 is a heart shape.

[0120] The second mating portion 4015 can also have other setting positions and shapes, which will not be listed one by one here. Its position and shape are restricted by the position and shape of the second fitting portion 205.

[0121] In another embodiment, the first end of the second mating portion 4015 is flush with the upper surface of the second receiving cavity 402 away from the second base 401, and the second end of the second mating portion 4015 is connected to the second base 401. Of course, the second mating portion 4015 and the second base 401 can be connecting members or integral parts, and the present application does not limit this.

[0122] In another alternative embodiment, the first end of the second mating portion 4015 can also be higher than the upper surface of the second base 401. Such a setting can avoid the situation that when the second connecting member 200 is received on the upper surface of the second base 401, the second connecting member 200 close to the upper surface of the second base 401 is likely to come out.

[0123] On the other hand, since the second adhesive member 207 is provided on the second connecting member 200, the lengths of the second adhesive member 207 extending from the sixth side 202 and the eighth side 204 can be the same or different. Therefore, on the sixth side wall 4012 and the eighth side wall 4014 corresponding to the sixth side 202 and the eighth side 204 of the second connecting member 200 in the second storage cavity 402, storage grooves for accommodating the second adhesive member 207 extending out of the second connecting member 200 are respectively formed. Since the storage grooves need to be formed on the sixth side wall 4012 and / or the eighth side wall 4014, for the convenience of description, the storage groove formed on the sixth side wall 4012 is referred to as the third storage groove 4016 herein, and the storage groove formed on the eighth side wall 4014 is referred to as the fourth storage groove 4017.

[0124] Exemplarily, if the lengths of the second adhesive member 207 extending out of the sixth side 202 and the eighth side 204 are the same, then the length of the third storage groove 4016 extending out of the sixth side wall 4012 can be set to be the same as the length of the fourth storage groove 4017 extending out of the eighth side wall 4014.

[0125] Exemplarily, if the lengths of the second adhesive member 207 extending out of the sixth side 202 and the eighth side 204 are different, then the length of the third storage groove 4016 extending out of the sixth side wall 4012 can be set to be different from the length of the fourth storage groove 4017 extending out of the eighth side wall 4014.

[0126] Exemplarily, if the length of the second adhesive member 207 extending out of the sixth side 202 is greater than the length of the second adhesive member 207 extending out of the eighth side 204, then the length of the third storage groove 4016 extending out of the sixth side wall 4012 can be set to be greater than the length of the fourth storage groove 4017 extending out of the eighth side wall 4014.

[0127] Of course, the shapes, sizes, etc. of the third storage groove 4016 and the fourth storage groove 4017 are restricted by the second adhesive member 207, and the specific structures of the first storage groove 3016 and the second storage groove 3017 are not limited herein.

[0128] In another alternative embodiment, a plurality of second storage cavities 402 may be provided on the second base 401. The shapes of the respective second storage cavities 402 are the same, and the respective second storage cavities 402 may be arranged adjacent to each other. In this way, on the one hand, space can be saved and space waste can be avoided; on the other hand, a larger number of first storage cavities 302 can be provided to accommodate more second connecting members 200.

[0129] In yet another alternative embodiment, the bottom of each second storage cavity 402 may be provided with a plurality of second material leakage holes 4018. The purpose of providing the second material leakage holes 4018 is to store foreign objects other than the second connecting member 200 and prevent these foreign objects from adhering to the second connecting member 200.

[0130] This application provides a battery connecting member and a tray. The battery connecting member includes a first connecting member and a second connecting member, wherein the first connecting member is used to connect the positive electrode of the battery, and the second connecting member is used to connect the negative electrode of the battery. Considering that the existing first connecting member and second connecting member are prone to confusion, this application provides a first assembly portion on the first connecting member and a second assembly portion on the second connecting member, and the installation positions and / or installation shapes of the first assembly portion and the second assembly portion are different. In this way, during the storage and use of the first connecting member and the second connecting member, the confusion between the two connecting members with different functions can be avoided, thereby further avoiding the occurrence of situations such as soldering head adhesion, soldering head damage, and bottom mold damage.
