Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0034] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0035] refer to Figures 1 to 5 According to the side composite metal structure of the embodiment of the present application, the first connecting member 100 and at least two second connecting members 200 are included. Along the first direction, one side of the first connecting member 100 is provided with an embedding groove 110, and the other side of the first connecting member 100 is also provided with an embedding groove 110. Each embedding groove 110 is provided with a V-shaped opening, and each V-shaped opening is arranged toward the first direction. Along the first direction, one of the second connecting members 200 is connected to one side of the first connecting member 100 and partially embedded in the embedding groove 110 located on the side, and the other second connecting member 200 is connected to the first side of the first connecting member 100 and partially embedded in the embedding groove 110 located on the side. 0 is connected to the other side of the first connecting member 100 and partially embedded in the embedding groove 110 located on the side, and each second connecting member 200 abuts against the side wall of the V-shaped opening, thereby realizing the embedding connection between the first connecting member 100 and the second connecting member 200. Compared with not having the embedding groove 110, a part of the second connecting member 200 is embedded in the embedding groove 110, which is beneficial to improving the bonding strength between the first connecting member 100 and the second connecting member 200, effectively avoiding separation or cracking of the side composite structure at the connection, and increasing the overall stability of the side composite material.

[0036] It should be noted that the V-shaped opening is a part of the engaging groove 110, and the side wall of the V-shaped opening can be understood as the groove wall of the engaging groove 110. The V-shaped opening does not limit the specific shape of the engaging groove 110. For example, the engaging groove 110 can be a V-shaped groove as a whole, or it can be a shape composed of a rectangle and a V-shaped opening. The V-shaped opening can provide guidance for the first connecting member 100 and the second connecting member 200, which is beneficial to a more precise connection between the first connecting member 100 and the second connecting member 200, and each second connecting member 200 abuts against the side wall of the V-shaped opening, that is, abuts against the groove wall of the engaging groove 110. After the side composite metal structure is rolled, the V-shaped opening can provide a tighter bite, which is beneficial to increase the stability of the connection between the first connecting member 100 and the second connecting member 200.

[0037] Specifically, the side composite metal structure has three directions of length, width and thickness, and the three directions of length, width and thickness are perpendicular to each other. The first direction is the width direction of the side composite metal structure. The first connector 100 and the second connector 200 are connected along the first direction, that is, side composite. The V-shaped opening of the engaging groove 110 is opened toward the first direction. The first connector 100 includes a first side and a second side in sequence along the first direction. The first side is connected to one of the second connectors 200, and the second side is connected to the other second connector 200. A portion of the second connector 200 is embedded in the engaging groove 110 along the first direction, and the second connector 200 is only embedded in the engaging groove 110 on the same side as the first connector 100, which can increase the bonding strength between the first connector 100 and the second connector 200. The first connector 100 may be made of silver, and the second connector 200 may be made of copper. The side composite metal material formed by the first connector 100 and the second connector 200 may be used as a fuse. The composite of silver and copper can better balance production cost and fusing performance.

[0038] It should also be noted that copper is harder and more ductile than silver, making it convenient to use as a substrate to manufacture a side composite metal structure. In addition, one of the second connectors 200 is connected to one side of the first connector 100, and the other second connector 200 is connected to the other side of the first connector 100, thereby providing good support for the first connector 100, which is beneficial to increasing the overall structural strength of the side composite metal structure.

[0039] refer to Figures 2 to 5In some embodiments, along the first direction, the second connecting member 200 is protruded with a fitting portion 210, which is embedded in the fitting groove 110 and abuts against the groove wall of the fitting groove 110. The fitting portion 210 is configured to match the size and shape of the fitting groove 110. The cooperation between the fitting portion 210 and the fitting groove 110 realizes the fitting connection between the first connecting member 100 and the second connecting member 200, further improving the stability of the connection between the first connecting member 100 and the second connecting member 200.

[0040] Specifically, the interlocking portion 210 can be in a triangular, circular, trapezoidal, rectangular or other shape. Accordingly, the shape of the interlocking groove 110 is matched with the shape of the interlocking portion 210, and the size of the interlocking groove 110 is consistent with the size of the interlocking portion 210, that is, the interlocking portion 210 is located in the interlocking groove 110 and fills the entire interlocking groove 110, so that the connection between the first connector 100 and the second connector 200 is tighter, and a gap between the first connector 100 and the second connector 200 is effectively avoided, which is beneficial to further improve the connection strength between the first connector 100 and the second connector 200, thereby ensuring the overall connection strength of the side composite metal structure.

[0041] It should be noted that the side composite metal structure needs to be rolled during the production process, and the rolling is carried out along the second direction, which is the thickness direction of the side composite metal structure. On the basis of the unchanged size of the connecting surface between the first connecting member 100 and the second connecting member 200, the arrangement of the interlocking portion 210 and the interlocking groove 110 can increase the contact area between the first connecting member 100 and the second connecting member 200, and the contact surfaces of the interlocking groove 110 and the interlocking portion 210 are inclined relative to the first direction and the second direction, which effectively limits the first connecting member 100 and the second connecting member 200 from detaching and cracking along the first direction and / or the second direction.

[0042] refer to Figures 3 to 5 In some embodiments, the embedding groove 110 includes a first embedding wall 111 and a second embedding wall 112, the first embedding wall 111 and the second embedding wall 112 are connected, the embedding portion 210 is provided with a first embedding plane 211 and a second embedding plane 212, the first embedding plane 211 is connected to the second embedding plane 212, the first embedding plane 211 abuts the first embedding wall 111, the second embedding plane 212 abuts the second embedding wall 112, a first angle a is formed between the first embedding wall 111 and the second embedding wall 112, a second angle b is formed between the first embedding plane 211 and the second embedding plane 212, and the first angle a is equal to the second angle b, so that the fit between the embedding portion 210 and the embedding groove 110 is tighter and the connection between the embedding portion 210 and the embedding groove 110 is more stable.

[0043] Specifically, the engaging groove 110 may be a V-shaped groove, and accordingly, the shape of the engaging portion 210 matches the shape of the engaging groove 110, and the first angle a and the second angle b are equal, so that the engaging portion 210 and the engaging groove 110 are more closely matched, thereby avoiding a gap at the connection between the first connector 100 and the second connector 200. When the side composite metal structure is manufactured, the second direction is perpendicular to the first direction, and the second direction is the thickness direction of the side composite metal structure. The first connector 100 is close to the second connector 200 along the second direction, and the first connector 100 is close to the second connector 200. The connecting member 100 is pressed against the second connecting member 200 and then rolled. After rolling, the second connecting member 200 and the first connecting member 100 are distributed along the first direction, that is, the second connecting member 200 is connected to one side of the first connecting member 100 along the first direction. The cooperation between the first embedding wall 111 and the first embedding plane 211, as well as the cooperation between the second embedding wall 112 and the second embedding plane 212, can provide guidance when the first connecting member 100 approaches the second connecting member 200 along the second direction, so as to facilitate determining the relative position of the first connecting member 100 and the second connecting member 200 before rolling.

[0044] It should be noted that the first embedding plane 211 and the first embedding wall 111 are arranged parallel to each other, and the second embedding plane 212 and the second embedding wall 112 are arranged parallel to each other. The side composite method is that the first connecting member 100 and the second connecting member 200 are connected in sequence along the first direction, so as to distinguish it from the layered composite method and other composite methods connected in sequence along the second direction.

[0045] refer to Figures 3 to 5 In some embodiments, the first angle a is 140° to 170°, and correspondingly, the second angle b is 140° to 170°. For example, the value range of the first angle a can be any value in any interval of 140° to 150°, 150° to 160°, and 160° to 170°, and the second angle b is equal to the first angle a. Since the side composite metal structure is thin as a whole, limiting the value range of the first angle a can better take into account the process difficulty and the connection strength between the first connector 100 and the second connector 200.

[0046] It should be noted that the actual action area of ​​the first connector 100 is the narrowest part of the width of the first connector 100 along the first direction, that is, along the width direction, the narrowest part of the width of the first connector 100 is the area where the first connector 100 is applied to the fuse material to play a role, and the first connector 100 is a silver material. Therefore, the angle of the first angle a should not be too large or too small. Limiting the range of the first angle a can avoid the situation where the first angle a is too small and it is difficult to open the fitting groove 110 on the first connector 100, and can also avoid the situation where the angle of the first angle a is too large and it is difficult to roll the composite angle standard. By limiting the angle of the first angle a, it is possible to better take into account the process difficulty of the production of the side composite metal structure, and ensure the overall structural strength of the side composite metal structure, and effectively avoid the separation or cracking of the side composite metal structure.

[0047] refer to Figure 1 and Figure 2 In some embodiments, the side composite metal structure includes at least two first connectors 100, and along the first direction, the second connectors 200 and the first connectors 100 are alternately connected in sequence, and along the first direction, the second connectors 200 are connected to both sides of the first connector 100, the first connector 100 is a silver material, and the second connector 200 is a copper material. Through the alternating connection of the second connectors 200 and the first connectors 100, the side is composited to form a side composite metal structure in which copper material and silver material are alternately connected, so as to better balance the performance and production cost of the side composite metal structure.

[0048] Specifically, along the first direction, the head end and the tail end of the side composite metal structure are both the second connector 200. The first connector 100 can be a silver material, and the second connector 200 can be a copper material. The first connector 100 and the second connector 200 are alternately connected in sequence along the first direction to form a side metal composite structure in which copper and silver materials appear alternately. Compared with silver, copper has good machining properties and better ductility. The scheme of alternating connection of copper and silver materials can better take into account the fusing performance and production cost of the side composite structure.

[0049] It should be noted that the number of the first connectors 100 can be adjusted according to the needs. In addition, the proportion of the first connectors 100 in the side composite metal structure can be changed by adjusting the size of the first connectors 100, which helps to meet different needs. In addition, the first connectors 100 can also be made of aluminum, palladium, titanium and other materials to achieve a combination of composite metal structures such as aluminum and copper, palladium and copper, titanium and copper, etc., thereby forming a side metal composite structure with different properties.

[0050] refer to Figures 1 to 3In some embodiments, along the first direction, the second connector 200 located at the head end and / or at the tail end is configured to have a larger extension size than the second connector 200 at other positions. The first connector 100 can be a silver material, and the second connector 200 can be a copper material. The second connector 200 located at the head end and / or the tail end has a larger extension size to facilitate further processing of the side composite metal structure. For example, in the process of further stamping, bending and other processes of the side composite metal structure, damage to the first connector 100 is effectively avoided. In addition, the extension size also facilitates positioning and punching on the side composite metal structure, which is beneficial to reducing the difficulty of the process.

[0051] Specifically, along the first direction, there are multiple first connectors 100 and second connectors 200, the first connectors 100 are made of silver, the second connectors 200 are made of copper, the second connectors 200 and the first connectors 100 are connected alternately in sequence, and along the first direction, the head end and the tail end of the side composite metal structure are both second connectors 200, and the second connectors 200 located at the head end and / or the tail end have a larger extension size than the second connectors 200 at other positions, that is, the second connectors 200 located at the head end and / or the tail end have a larger width, which is convenient for positioning and punching operations on the second connectors 200 located at the head end and / or the tail end. It can also avoid damaging the first connector 100, and compared with positioning and punching on the first connector 100, positioning and punching on the second connector 200 has a lower cost, while also taking into account the performance of the side composite metal structure.

[0052] refer to Figures 3 to 5 In some embodiments, the first connecting member 100 includes a first connecting portion 120 and a second connecting portion 130, the first connecting portion 120 is connected to the second connecting portion 130, the first connecting portion 120 and the second connecting portion 130 jointly define an engaging groove 110, the first connecting portion 120 and the second connecting portion 130 are both connected to the second connecting member 200, and are used to jointly engage with the second connecting member 200 to achieve the connection between the first connecting member 100 and the second connecting member 200. Compared with the integrally formed first connecting member 100 and the second connecting member 200, the first connecting portion 120 and the second connecting portion 130 can be connected to the second connecting member 200 respectively, which is beneficial to reducing the difficulty of connecting the first connecting member 100 and the second connecting member 200, more conveniently achieving the connection between the first connecting member 100 and the second connecting member 200, and facilitating the production and manufacturing of the side composite metal structure.

[0053] Specifically, the first connection part 120 and the second connection part 130 are connected to the second connection member 200 in sequence. The specific connection steps include the first connection part 120 approaching and abutting the second connection member 200, realizing the connection between the first connection part 120 and the first connection member 100 by rolling, the second connection part 130 approaching and abutting the second connection member 200 and the first connection part 120, and rolling again to realize the connection between the second connection part 130 and the second connection member 200, and the connection between the second connection part 130 and the first connection part 120. After the connection is completed, the first connection part 120 and the second connection part 130 jointly define the embedding groove 110, and a part of the second connection member 200 is located in the embedding groove 110, so that the second connection part 130 is connected to the first connection part 120 while the second connection member 200 is embedded in the embedding groove 110, which is more convenient for the production and manufacturing of the side composite metal structure.

[0054] refer to Figures 4 to 7 In some embodiments, along the second direction, the extension dimension ratio of the first connecting portion 120 to the first connecting member 100 is 0.6 to 0.65, and the second direction is perpendicular to the first direction, that is, along the thickness direction of the side composite metal structure, the thickness of the first connecting portion 120 accounts for 60% to 65% of the first connecting member 100, making it easier to connect the first connecting member 100 to the second connecting member 200.

[0055] It should be noted that the second direction is the thickness direction of the side composite metal structure. When the side composite metal structure is manufactured, it is necessary to use the second connector 200 as the base material to open a groove and fill the first connector 100. The first connecting part 120 and the second connecting part 200 are first connected. On the basis of the first connecting part 120 and the second connecting part 200 being connected, the second connecting part 130 is then connected to the second connecting part 200. The connection between the second connecting part 130 and the second connecting part 200 is affected by the connection accuracy between the first connecting part 120 and the second connecting part 200, which is more difficult to control than the connection between the first connecting part 120 and the second connecting part 200. Therefore, the extension dimension of the first connecting part 120 along the second direction is set to account for 60% to 65% of the total extension dimension of the first connecting part 100, which makes it easier to control the connection between the first connecting part 100 and the second connecting part 200. Among them, the proportion of the first connecting part 120 to the first connecting part 100 should not be too large or too small, which is beneficial to reduce the manufacturing difficulty.

[0056] refer to Figures 4 to 7In some embodiments, the first connecting part 120 and / or the second connecting part 130 include a first plane 140 and a second plane 150. The first plane 140 is parallel to the second plane 150, and the first plane 140 extends along a first direction. The first plane 140 is used to provide rolling, which helps the rolling device to roll the side composite metal structure more flat. The second plane 150 is used for connecting the first connecting part 120 and the second connecting part 130, which can effectively avoid gaps in the connection between the first connecting part 120 and the second connecting part 130.

[0057] Specifically, along the second direction, the first connecting part 120 and the second connecting part 130 are provided with a first plane 140 and a second plane 150. The first connecting part 120 and the second connecting part 130 are connected by the second plane 150, so that the connection between the first connecting part 120 and the second connecting part 130 is tighter. In addition, the second plane 150 is a part of the outer surface of the side composite metal structure, which is used for the calendering device to calender, so as to facilitate the calendering of the side composite metal structure to be smoother.

[0058] refer to Figures 4 to 7 In other embodiments, a first embedding wall 111 is provided on the first connecting portion 120, and a second embedding wall 112 is provided on the second connecting portion 130. The first connecting portion 120 and the second connecting portion 130 are both provided with a first plane 140 and a second plane 150. The first connecting portion 120 and the second plane 150 of the second connecting portion 130 are arranged opposite to each other and are connected by the second plane 150. The second plane 150 is used to ensure a tight connection between the first connecting portion 120 and the second connecting portion 130. The first plane 140 and the second plane 150 of the first connecting portion 120 are connected by the first embedding wall 111, and the first plane 140 and the second plane 150 of the second connecting portion 130 are connected by the second embedding wall 112. The first embedding wall 111 and the second embedding wall 112 define an embedding groove 110 for improving the connection strength between the first connecting member 100 and the second connecting member 200. The first plane 140 also facilitates the rolling device to roll the side composite metal structure, so that the connection between the various parts of the side composite metal structure is tighter and more stable.

[0059] refer to Figures 1 to 3 In some embodiments, along the second direction, the first connector 100 and the second connector 200 are configured to have the same extension dimension, and the extension dimension along the second direction is 0.07 mm to 4.6 mm. The second direction is the thickness direction, that is, the thickness range of the side composite metal structure is 0.07 mm to 4.6 mm. Within this thickness range, it is beneficial to ensure the fusing performance of the side composite metal structure.

[0060] Specifically, the thickness range of the side composite metal structure can be any value within any interval of 0.07mm to 0.079mm, 0.1mm to 0.2mm, 0.3mm to 1mm, 1mm to 2mm, 2mm to 3mm, 3mm to 4mm and 4mm to 4.6mm. For example, the above thickness values ​​can be 0.07mm, 0.1mm, 0.15mm and other thickness values, so as to take into account the fusing performance and structural strength of the side composite metal structure.
