Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to an anti-condensation wiring structure for wiring posts of high and low temperature boxes of lithium batteries. Background Art

[0002] Lithium batteries are tested under power in high and low temperature boxes. They are connected to the power supply through terminals. Multiple sets of terminals can be installed to test multiple sets of batteries. Most of the terminals are made of copper, and copper has strong thermal conductivity. When doing low temperature tests, the low temperature will be transmitted to the outside of the box through the terminals and combine with the air outside the box to form condensation. In mild cases, there will be dripping, and in severe cases, it will cause the electrodes to short.

[0003] The patent document with application number CN217562859U discloses a lithium battery high and low temperature box terminal anti-condensation wiring structure, which includes a high and low temperature box body, an insulating plate is arranged on one side of the high and low temperature box body, a plurality of terminal posts are arranged on the insulating plate, the terminal posts are screwed and fixed on the insulating plate by fixing nuts, one end of the terminal post is connected to the power supply to be tested, one end of the terminal post extends out of the high and low temperature box body, a terminal post protection box is arranged outside the one end of the terminal post, and a PCT heater is fixedly arranged in the terminal post protection box.

[0004] The structure of the terminal protection box with this structure is combined with the structure of the PCT heater to replace the original structure of heating with a wrapped heating wire. The PTC heater is equipped with a temperature regulator and a fan. When the temperature in the box reaches below 13°C, the PTC heater starts to work, and then observes the condensation of the terminal, and appropriately adjusts the temperature adjustment knob of the regulator to an appropriate temperature to heat the air in the protection box to prevent condensation. However, in actual use, the interior of the protection box is in a sealed space. When the lithium battery high and low temperature box is in use, the terminal will have a certain resistance during operation, and thus will generate a certain amount of heat. Since the closed environment cannot effectively dissipate heat, the heat generated by the terminal cannot be quickly dissipated, which may cause the temperature in the protection box to rise, which may affect the working effect of the lithium battery high and low temperature box, and may even have an adverse effect on the battery, and there is even the possibility of fire. To address the above problems, we have introduced a lithium battery high and low temperature box terminal anti-condensation wiring structure. Utility Model Content

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application.

[0023] The utility model discloses a condensation-proof wiring structure for a lithium battery high and low temperature box terminal, which is mainly used in lithium battery scenarios.

[0024] Reference Figure 1 and Figure 2 A lithium battery high and low temperature box terminal anti-condensation wiring structure comprises: a high and low temperature box body 1, a first box door 2 is arranged on one side of the high and low temperature box body 1, a mounting groove 21 is opened on one side of the high and low temperature box body 1, an insulating plate 8 is slidably connected inside the mounting groove 21, a terminal body 9 is equidistantly arranged inside the insulating plate 8, a protection box 3 is fixedly connected to one side of the high and low temperature box body 1, a second box door 4 is arranged on one side of the protection box 3, wiring holes 5 are equidistantly opened on one side of the second box door 4, a heating component is arranged inside the protection box 3, a through groove 6 is opened on one side of the protection box 3, two ventilation plates 7 are rotatably connected inside the through groove 6, an adjustment component is arranged on one side of the inner wall of the protection box 3, and the adjustment component is used to drive the ventilation plate 7 to swing.

[0025] In the above technical scheme, it is taken into account that there will be a certain resistance in the working process of the terminal, so a certain amount of heat will be generated. Since the closed environment of the protection box 3 cannot effectively dissipate heat, in order to solve this problem, the specific operation is as follows: by setting an adjustment component to drive the ventilation plate 7 on one side of the protection box 3 to swing, thereby opening the through slot 6, so that external air can enter the protection box 3, and the heat in the protection box 3 can also be discharged through the through slot 6, thereby dissipating the heat of the terminal body 9. After the heat dissipation is completed, the adjustment component is used to drive the ventilation plate 7 to swing back and block the through slot 6 again, which is conducive to the rapid dissipation of the heat generated by the terminal, so that the normal temperature can be maintained in the protection box 3, thereby improving the working effect of the high and low temperature box of the lithium battery, and even extending the service life of the battery, and reducing the possibility of fire.

[0026] Reference Figures 2 to 6 In a preferred embodiment, the adjustment component includes a first fixed block 14, which is equidistantly fixedly connected to one side of the inner wall of the protection box 3, one side of the first fixed block 14 is rotatably connected to the gear 12, and a chain 13 is arranged on the outer side of the gear 12, and a micro motor box 15 is arranged on one side of the first fixed block 14, and one end of the output shaft of the micro motor box 15 is fixedly connected to the rotating shaft of one of the gears 12, and the adjustment component also includes a connecting block 17, which is arranged at one end of the gear 12, and a first connector 18 is arranged on one side of the connecting block 17, and a second fixed block 20 is fixedly connected to one side of the ventilation plate 7, and a second connector 19 is arranged on one side of the second fixed block 20, and a connecting rod 16 is rotatably connected between the outer sides of the first connector 18 and the outer sides of the second connector 19;

[0027] In the above technical scheme, the problem that the heat in the protection box 3 cannot be dissipated is taken into consideration. In order to solve this problem, the specific operations are as follows: start the micro motor box 15 to drive the gear 12 to rotate, and use the meshing relationship between the gear 12 and the chain 13 to make the two gears 12 rotate synchronously, and then drive the connecting block 17 to swing along the arc line, and push the ventilation plate 7 through the first connecting head 18, the connecting rod 16 and the second connecting head 19, and make the ventilation plate 7 swing through the rotating shaft of the ventilation plate 7, and then open the through groove 6, so that the heat in the protection box 3 can be dissipated and sent out, and the outside air can come in for ventilation, so that the protection box 3 can always maintain a normal temperature, and there is a gap inside the first connecting head 18 and the second connecting head 19 for the connecting rod 16 to move.

[0028] Reference Figure 2 and Figure 3 In a preferred embodiment, the heating component includes a heater 10, which is fixedly mounted on one side of the inner wall of the protection box 3, and a temperature sensor 11 is provided on one side of the inner wall of the protection box 3; the structure of the protection box 3 cooperating with the heater 10 replaces the original structure of heating by winding the heating wire. When the temperature sensor 11 detects that the temperature inside the protection box 3 is low, the heater 10 starts to work, thereby increasing the temperature in the protection box 3. By heating, condensation of the air inside the protection box 3 is prevented, thereby protecting the terminal body 9. The heater 10 and the temperature sensor 11 are electrically connected.

[0029] Refer to 1 and Figure 3 In a preferred embodiment, the high and low temperature box body 1 and the insulating plate 8 are connected by bolts; the insulating plate 8 can be fixed to one side of the high and low temperature box body 1 by using bolts, so that the terminal body 9 is installed on the high and low temperature box body 1.

[0030] Working principle: When in use, connect the wire to the terminal body 9 through the wiring hole 5. When the temperature sensor 11 detects that the temperature inside the protection box 3 is low, the heater 10 starts to work, thereby increasing the temperature in the protection box 3. By heating, condensation of the air inside the protection box 3 is prevented, thereby protecting the terminal body 9. During the long-term operation of the terminal body 9, a large amount of heat will be dissipated and retained in the protection box 3. When the temperature sensor 11 detects that the temperature inside the protection box 3 is too high, the micro motor box 15 is started to drive the gear 12 to rotate, and the meshing relationship between the gear 12 and the chain 13 is used to make the two gears 12 rotate synchronously, and then Then, the connecting block 17 is driven to swing along the arc line, and the ventilation plate 7 is pushed through the first connecting head 18, the connecting rod 16 and the second connecting head 19. The ventilation plate 7 is swung through the rotating shaft of the ventilation plate 7, and then the through slot 6 is opened to allow the heat in the protection box 3 to dissipate and the outside air to come in for ventilation. When the temperature in the protection box 3 is normal, the micro motor box 15 is started to drive the gear 12 to rotate in the opposite direction, and the connecting block 17 is driven to return to its original position, so that the ventilation plate 7 can be swung back and completely closed, and the through slot 6 is blocked again. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
