Description

Technical Field

[0001] The utility model belongs to the technical field of battery pack connection accessories, in particular to a modular battery pack junction box. Background Art

[0002] In order to facilitate customers to connect the terminal to the battery pack, most of the junction boxes are installed directly on the battery rack. There are many types of junction boxes, including single input / output type and multi-input / output type. The design and selection should be based on different usage requirements.

[0003] Due to excessive demands, the types of junction boxes cannot be unified. A large number of junction boxes with different structures are needed to meet various terminal needs. However, the junction boxes are not related to each other, and multiple junction boxes are placed randomly, occupying the usable space. Utility Model Content

[0008] As a preferred embodiment of the above technical solution, an electronic component is arranged on the top of the mounting platform, one end of the electronic component is connected to the input end through a bolt assembly, and the other end of the electronic component is connected to the output end through a bolt assembly.

[0009] The beneficial effects of the utility model are:

[0010] 1. With the cooperation of the mortise and tenon structure, two adjacent junction box bodies are interconnected, and multiple junction boxes are arranged in order in the working space, so that the connection wires at the output and input ends are arranged more neatly, avoiding entanglement between the connection wires;

[0011] 2. When a short circuit occurs inside the junction box, the detachment component will detach the plug-in structure, causing the junction box on one side to move a certain distance, and the detachment component in the junction box on the other side will also detach the plug-in structure due to the increase in temperature, thereby isolating the junction box with the short circuit problem from the normal junction box to avoid affecting other normal junction boxes.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.

[0020] Example

[0021] Figure 1-Figure 4 In the present invention, a modular battery pack junction box comprises: a junction box body 10 and a protective cover 30, wherein the junction box body 10 has card holes around the open position, the protective cover 30 has a convex card, the junction box body 10 and the protective cover 30 are snap-fitted, a mounting platform 11 is arranged inside the junction box body 10, a plug-in tenon structure 12 is arranged on one side of the junction box body 10, and a plug-in mortise structure 13 is arranged on the other side of the junction box body 10, and the plug-in tenon structure 12 matches the plug-in mortise structure 13.

[0022] When multiple junction boxes are used, two adjacent junction box bodies 10 are connected via the mortise and tenon structures 13 and the tenon and tenon structures 12, so that the junction box bodies 10 can be connected to each other. The protective cover 30 is inserted into the card hole of the junction box body 10 through the convex card. The card hole cooperates with the convex card, so that the box body and the protective cover 30 can be firmly matched to protect the inside of the junction box body 10.

[0023] With the cooperation of the mortise and tenon structures 13 and 12, two adjacent junction box bodies 10 are interconnected, and multiple junction boxes are orderly arranged in the working space, so that the connection wires of the output terminal 42 and the input terminal 41 are arranged more neatly to avoid entanglement between the connection wires.

[0024] Figure 2 In the figure, electronic components 40 are arranged on the top of the mounting platform 11. The electronic components 40 are electronic components such as circuit boards and copper bars. One end of the electronic components 40 is connected to the input end 41 through a bolt assembly, and the other end of the electronic components 40 is connected to the output end 42 through a bolt assembly.

[0025] The electronic component 40 is mounted on the mounting platform 11, and the input terminal 41 and the output terminal 42 are connected to the two ends of the electronic component 40 using a bolt assembly. At the same time, the bolt assembly fixes the electronic component 40 on the mounting platform 11 to prevent the input terminal 41 or the output terminal 42 from being separated from the junction box body 10.

[0026] Figure 5-Figure 6 In the figure, a disengagement component 20 is arranged between the plug-in mortise structure 13 and the junction box body 10, and the disengagement component 20 includes a limit block 21 and a connecting bolt 22. The limit block 21 is movably inserted in the junction box body 10, and the limit block 21 is fixedly connected to the plug-in mortise structure 13, a disengagement spring 23 is arranged between one end of the connecting bolt 22 and the mounting platform 11, a limit ring 24 is arranged on the outer side of the connecting bolt 22, and a plurality of connecting blocks 25 are fixedly connected between the limit ring 24 and the connecting bolt 22.

[0027] The connecting block 25 is made of polyethylene, and the melting temperature of the connecting block 25 is 50-60 degrees.

[0028] When a short circuit occurs in the electronic component 40, the temperature inside the junction box body 10 increases. When the temperature reaches 50-60 degrees, the connecting block 25 melts and disconnects the connection between the limit ring 24 and the connecting bolt 22. The disengagement spring 23 in the compressed state resets and pushes the limit block 21 and the plug-in mortise structure 13 through the connecting bolt 22, so that the junction box on one side is pushed away, and the disengagement component 20 in the junction box on the other side also pushes the plug-in mortise structure 13 due to the increase in temperature, thereby isolating the junction box with the short circuit problem from the normal junction box.

[0029] When a short circuit occurs inside the junction box, the disengagement component 20 disengages the plug-in mortise structure 13, causing the junction box on one side to move a certain distance, and the disengagement component 20 in the junction box on the other side also disengages the plug-in mortise structure 13 due to the increase in temperature, thereby isolating the junction box with the short circuit problem from the normal junction boxes to avoid affecting other normal junction boxes.

[0030] Figure 5-Figure 6 In the embodiment, the limit block 21 and the inserting mortise structure 13 are integrally formed, and the connecting bolt 22 is threadedly sleeved with the limit block 21 and the inserting mortise structure 13.

[0031] The limiting block 21 and the plug-in mortise structure 13 are integrally formed, which facilitates the production of the limiting block 21 and the plug-in mortise structure 13. The plug-in mortise structure 13 is limited by the limiting block 21, and the plug-in mortise structure 13 will not move on the junction box body 10.

[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
