Detailed Embodiments

[0036] The technical solution of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0037] In an embodiment of the present application, a connector bracket 100 is provided. For the specific structure of the connector bracket 100, please refer to Figures 1 to 5 , which includes a bracket main body 110, a side cover 120, and a top cover 130. Among them, the side cover 120 and the bracket main body 110 enclose a receiving cavity 140 with openings at both upper and lower ends. The lower opening of the receiving cavity 140 is clamped with a connector, and a busbar socket communicating with the receiving cavity 140 is provided on the side cover 120 and / or the bracket main body 110; the top cover 130 is used to cover the upper opening of the receiving cavity 140 and the busbar socket.

[0038] According to the connector bracket 100 of the present application, the connector is clamped in the lower opening of the receiving cavity 140, which can prevent the busbar from rotating during installation, resulting in its shaking and tilting, thereby ensuring the electrical clearance, creepage distance, and the electrical connection stability between the busbar and the electrical components in the battery pack. By enclosing the receiving cavity 140 with the side cover 120 and the bracket main body 110 and covering the upper opening of the receiving cavity 140 and the busbar socket with the top cover 130, the connector and the busbar in the receiving cavity are protected, achieving the purpose of dust and water protection, thereby eliminating potential safety hazards that may exist in actual use.

[0039] As Figure 3 and Figure 5 shown, the bracket main body 110 is provided with a receiving groove 111 with openings at both upper and lower ends. The lower opening of the receiving groove 111 is clamped with a connector, which plays a role in limiting and fixing the connector. An open side is formed on one side of the receiving groove 111 close to the side cover 120, and the side cover 120 covers the open side of the receiving groove 111 to form the receiving cavity 140, which plays a role in protecting the connector and the busbar from dust, water, and electric shock.

[0040] As Figure 3As shown, the connector includes an insulating body and connecting terminals. The accommodating groove 111 includes a first accommodating groove 1111 and a second accommodating groove 1112 which are arranged from bottom to top and communicate with each other, so that the insulating body and the connecting terminals are respectively limited in the first accommodating groove 1111 and the second accommodating groove 1112. Among them, the size and contour of the first accommodating groove 1111 correspond to the size and contour of the insulating body, so that the insulating body can be stably clamped in the first accommodating groove 1111, and the copper busbar is connected to the connecting terminal in the second accommodating groove 1112 through a copper busbar socket. Exemplarily, the copper busbar and the connecting terminal are fixedly connected by screwing with fasteners. Since the insulating body and the connecting terminals are respectively limited in the first accommodating groove 1111 and the second accommodating groove 1112, the copper busbar is limited and fixed, preventing the copper busbar from rotating synchronously with the fastener when the fastener is tightened, resulting in its own shaking and tilting, thus affecting the subsequent assembly of the battery pack.

[0041] As Figure 3 and Figure 5 shown, the side cover 120 covers the first accommodating groove 1111 and the second accommodating groove 1112 to form a first accommodating cavity 141 and a second accommodating cavity that communicate with each other. The copper busbar socket communicates with the second accommodating cavity, so that the copper busbar extends into the second accommodating cavity through the copper busbar socket and is fixedly connected to the connecting terminal in the second accommodating cavity.

[0042] As Figure 3 shown, a longitudinally extending support portion 112 is provided in the second accommodating groove 1112. The support is used to support the connecting terminal. The connecting terminal is placed on the top surface of the support portion 112. By providing the support portion 112 in the second accommodating groove 1112, not only can the connecting terminal and the copper busbar be supported, but also the copper busbar can be prevented from rotating synchronously with the fastener when the fastener is tightened.

[0043] As Figure 3 shown, the support portion 112 is provided with a weight-reducing groove 1121, and an open end is formed on one side of the accommodating groove 111 close to the side cover 120, which is beneficial to reducing the weight of the connector bracket 100, thereby realizing the lightweight of the battery pack.

[0044] As an embodiment not shown, a connecting hole penetrating through the weight-reducing groove 1121 is provided on the support portion 112, so that the fastener sequentially passes through the copper busbar, the connecting terminal and the support portion 112 to realize the fixed connection between the copper busbar and the connecting terminal and ensure the connection strength between the two.

[0045] As Figure 3 and Figure 5As shown, a plurality of connection terminals are arranged at intervals in a first direction, at least two support portions 112 are arranged at intervals in the first direction, at least one connection terminal is clamped between the two support portions 112. The second accommodation groove 1112 includes a first side wall and a second side wall arranged opposite to each other in the first direction. Exemplarily, three connection terminals are arranged at intervals in the first direction. The support portion 112 is integrally connected to the bottom wall of the second accommodation groove 1112. Three support portions 112 with different heights are arranged at intervals in the first direction. Clamping spaces for clamping the connection terminals are respectively formed between the first side wall and the adjacent support portion 112, between two adjacent support portions 112, and between the second side wall and the adjacent support portion 112, so as to divide the second accommodation groove 1112 into three clamping grooves 1113 arranged at intervals in the first direction, so that the three connection terminals are respectively clamped in the corresponding clamping grooves 1113. Each clamping groove 1113 is respectively provided with a through hole 1114 communicating with the first accommodation groove 1111.

[0046] The first direction is substantially perpendicular to the height direction of the connector bracket 100. The first direction may be substantially parallel to the length direction of the connector bracket 100. Of course, the first direction may also be substantially parallel to the width direction of the connector bracket 100. For the convenience of description, in the present embodiment, the first direction is substantially parallel to the length direction of the connector bracket 100.

[0047] As Figure 3 shown, a plurality of connection terminals are arranged at intervals in the first direction, and a longitudinally extending partition plate 113 is arranged between two adjacent connection terminals. Exemplarily, three connection terminals are arranged at intervals in the first direction. Since the three connection terminals are relatively close, it is difficult to meet the requirements of the UL2580 standard for the electrical clearance and creepage distance after the copper busbar is installed and fixed. Therefore, two baffles are arranged in the middle part of the bracket body 110, which can effectively increase the electrical clearance and creepage distance between the copper busbars.

[0048] For the specific structure of the top cover 130, please refer to Figures 1 to 5 , which includes a cover body 131 and a shielding plate 132. Among them, the cover body 131 is used to cover the upper opening of the accommodation cavity 140; the shielding plate 132 is detachably connected to the cover body 131, and the shielding plate 132 is used to cover the copper busbar socket. By providing the shielding plate 132 for covering the copper busbar interface, the copper busbar socket without the copper busbar inserted can be blocked, which not only achieves the effects of dust prevention and waterproofing, but also can prevent accidental contact with the live body.

[0049] As Figure 1As shown in the figure, the baffle 132 is integrally formed on the cover 131, and the baffle 132 and the cover 131 are detachably connected by a brittle connecting member 133. When an external force is applied to the baffle 132, the structure of the brittle connecting member 133 can be damaged, thereby releasing the connection between the baffle 132 and the cover 131, realizing the disassembly of the baffle 132, and further opening the corresponding busbar socket of the baffle 132 to enable the busbar to pass through the busbar socket.

[0050] The number of baffles 132 is the same as the number of busbar sockets. Exemplarily, as Figure 1 shown, there is one busbar socket provided on the bracket main body 110, and two busbar sockets are provided on the side cover 120. The three baffles 132 are respectively detachably connected to the cover 131 through brittle connecting members 133, and the three baffles 132 respectively correspond to the three busbar sockets one by one. At the same time, the size of the baffle 132 also corresponds to the opening size of the busbar socket, so that the baffle 132 can block the busbar socket.

[0051] As Figures 1 to 5 shown, the bracket main body 110 and the side cover 120 are detachably connected through a first snap structure 150, which not only facilitates the rapid assembly of the bracket main body 110 and the side cover 120, improves the assembly efficiency of the battery pack, but also enables the disassembly of the bracket main body 110 and the side cover 120, facilitating the maintenance or replacement of components.

[0052] As Figure 3 and Figure 4 shown, at least two first snap structures 150 are arranged on both sides of the bracket main body 110 and the side cover 120 along the first direction, ensuring the firm connection between the bracket main body 110 and the side cover 120, thereby enhancing the overall stability of the connector bracket 100.

[0053] As Figure 1 and Figures 3 to 5 shown, at least two first snap structures 150 are arranged at intervals along the height direction on one side of the bracket main body 110 and the side cover 120, further enhancing the firmness of the connection structure between the bracket main body 110 and the side cover 120.

[0054] As Figures 1 to 5 shown, the first snap structure 150 includes a first snap 151 provided on the bracket main body 110 and a first lug 152 provided on the side cover 120. The first snap 151 can be snap-connected to the first lug 152, thereby quickly fixing the side cover 120 on the bracket main body 110.

[0055] As Figure 1As shown, the side cover 120 and the top cover 130 are detachably connected by the second snap structure 160, which not only facilitates the quick assembly of the side cover 120 and the top cover 130, improving the assembly efficiency of the battery pack, but also allows the side cover 120 and the top cover 130 to be disassembled for easy maintenance or replacement of components.

[0056] As Figure 1 shown, the second snap structure 160 includes a second snap 161 provided on the side cover 120 and a second lug 162 provided on the top cover 130. The second snap 161 can be snap-fitted with the second lug 162, thereby quickly fixing the top cover 130 on the side cover 120.

[0057] As Figure 4 shown, the bracket main body 110 and the top cover 130 are detachably connected by the third snap structure 170, which not only facilitates the quick assembly of the bracket main body 110 and the top cover 130, improving the assembly efficiency of the battery pack, but also allows the bracket main body 110 and the top cover 130 to be disassembled for easy maintenance or replacement of components.

[0058] As Figure 4 shown, at least two third snap structures 170 are arranged at intervals along the second direction on one side of the bracket main body 110 and the top cover 130, further enhancing the firmness of the connection structure between the bracket main body 110 and the top cover 130.

[0059] The second direction is perpendicular to the first direction and is substantially perpendicular to the height direction of the connector bracket 100. The second direction can be substantially parallel to the length direction of the connector bracket 100. Of course, the second direction can also be substantially parallel to the width direction of the connector bracket 100. For the convenience of description, in this embodiment, the second direction is substantially parallel to the width direction of the connector bracket 100.

[0060] As Figure 4 shown, the third snap structure 170 includes a third snap 171 provided on the bracket main body 110 and a third lug 172 provided on the top cover 130. The third snap 171 can be snap-fitted with the third lug 172, thereby quickly fixing the top cover 130 on the bracket main body 110.

[0061] In the embodiment of the present application, a battery pack is also provided, which includes the connector bracket 100 in the above embodiment, and thus includes all the advantages of the connector bracket 100, which will not be elaborated here.
