Flame retardant plates are provided around the outer wall of the battery body. A positive electrode end and a negative electrode end are provided at the top of the battery body, and the positive electrode end and the negative electrode end both pass through the positive electrode perforation and the negative electrode perforation of the flame retardant plate. Buffer members are symmetrically provided on the front and rear sides of the battery body. The buffer member includes a rectangular plate, a connecting spring and a connecting seat. The beneficial effects of the utility model are as follows: The connecting spring of the buffer member provided on the outside of the battery body can be appropriately contracted and expanded during the charging and discharging process of the lithium battery cell, preventing breakage or explosion due to excessive pressure; the setting of the flame retardant plate improves its safety; the provided connecting member enables the housing to be in non-close contact with the battery and has elasticity, improving its shock absorption and service life.

[0004] However, the following problems still exist in the existing lithium batteries:

[0005] Before the lithium battery is connected to an external device, a section of positive electrode wire and negative electrode wire are often reserved outside the battery pack. However, after the positive electrode wire and negative electrode wire are reserved, they are often not taken out and used for a long time. During this period, it is possible that the connectors sleeved outside the positive electrode wire and negative electrode wire are damaged or detached due to external extrusion, resulting in contact between the positive electrode wire and the negative electrode wire, causing short circuit and even explosion.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1 - 5 , a lithium battery capable of protecting the wiring, including a battery body 1 and a connecting wire head 2 installed on one side of the battery body 1. A protective case 3 is connected to one side of the battery body 1 close to the connecting wire head 2. A storage cavity 31 is opened on the side of the protective case 3 away from the battery body 1. The length and width of the storage cavity 31 are not less than the length and width of the connecting wire head 2. A card slot 34 is opened on the side of the storage cavity 31 away from the connecting wire head 2, and the front end of the connecting wire head 2 is inserted into the card slot 34.

[0022] A lithium battery capable of protecting the wiring in the present utility model is similar in structure to the existing lithium battery, such as a new type of lithium battery disclosed in the patent with the publication number CN212810429U. As Figures 1 to 5 shown, when the lithium battery capable of protecting the wiring in the present utility model is stored, first, the battery body 1 is placed into an external storage box, and then the connecting wire head 2 on one side of the battery body 1 is folded down until it is folded into the storage cavity 31 of the protective case 3. Then, the plug at the front end of the connecting wire head 2 is inserted into the card slot 34 on one side of the storage cavity 31, so as to avoid falling off. At this time, the connecting wire head 2 of the battery body 1 is inside the protective case 3, so that it will not be crushed or fall off; it is particularly worth noting here that: the protective case 3 and the battery body 1 can be bonded, clamped or other connection methods, so that when the battery body 1 needs to be used later, the protective case 3 can be removed as a whole, and thus it will not hinder the connection of the battery body 1.

[0023] Please mainly refer to Figures 1 - 5 , a connecting plate 6 is fixedly connected to the side of the protective case 3 close to the connecting wire head 2, and a sleeve ring 7 is fixedly connected to the other end of the connecting plate 6. The sleeve ring 7 is sleeved on the outer wall of the connecting wire head 2 and is slidably connected to the connecting wire head 2. By providing the connecting plate 6 and the sleeve ring 7, when the connecting wire head 2 needs to be stored, only the connecting plate 6 needs to be slid down. When the connecting plate 6 descends, it will drive the sleeve ring 7 downward, and thus the connecting wire head 2 can be folded down by the sleeve ring 7 until it is folded into the storage cavity 31.

[0024] Please mainly refer to Figures 1 - 5, a moving groove 33 is penetrated and opened on one side of the storage cavity 31 close to the battery body 1, and the outer wall of the connecting plate 6 is slidably connected with the inner wall of the moving groove 33. By providing the moving groove 33, the connecting plate 6 can be stored.

[0025] Please mainly refer to Figures 1 - 5 , sliding grooves 32 are opened on both sides of the storage cavity 31, a slider 4 is fixedly connected to the side of the connecting plate 6 away from the battery body 1, and both sides of the slider 4 are slidably connected with the inner walls of the two sliding grooves 32 respectively. By providing the slider 4 and the sliding grooves 32, it is more convenient to apply force when sliding the connecting plate 6 downward or lifting it upward.

[0026] Please mainly refer to Figures 1 - 5 , a connection port 41 is opened on the side of the slider 4 away from the battery body 1, a clamping block 5 is fixedly connected to the inner wall of the connection port 41, two clamping openings 51 are opened on the side of the clamping block 5 away from the battery body 1, the inner diameters of the two clamping openings 51 are the same as the outer diameters of the two wires of the connection head 2, and the outer walls of the two wires of the connection head 2 are slidably connected with the inner walls of the clamping openings 51. By providing the clamping block 5 and the clamping openings 51, after the front plug of the connection head 2 is inserted into the card slot 34, the positive wire and the negative wire can be clamped by the clamping openings 51, increasing the clamping force on the whole connection head 2 and preventing it from falling off.
