In addition, the battery can also be a lead-acid battery, a cadmium-nickel battery, a metal hydride battery, a lithium ion battery or a fuel cell, etc., and the utility model is not limited in particular.
In the embodiment of the present invention, as shown in fig. 1, taking a common battery as an example, the battery main body 10 is substantially cylindrical, and includes a housing 11 (generally made of steel), a raised positive electrode region 12 (made of metal conductive material) is disposed at one end of the housing 11, and a negative electrode region 13 (made of metal conductive material) is disposed at the other end. When the positive electrode region 12 and the negative electrode region 13 are connected to an external circuit and form a circuit, the battery main body 10 may supply power to the outside.
In the embodiment of the present invention, in order to ensure the stability of the output voltage of the battery main body 10, generally, a battery protection plate 20 is further disposed on the battery main body 10. One side of the battery protection plate 20 faces the positive electrode area 12, the other side of the battery protection plate is provided with a protection plate positive electrode 21 and a protection plate negative electrode 22, the first insulation sheet 40 is attached to the protection plate positive electrode 21 and the protection plate negative electrode 22, a first conducting wire 23 is led out from the protection plate positive electrode 21, and a second conducting wire 24 is led out from the protection plate negative electrode 22.
In the embodiment of the present invention, in order to realize the connection between the battery main body 10 and the battery protection plate 20, the waterproof battery 200 further includes a first conductive sheet 70 and a second conductive sheet 80, the first conductive sheet 70 is disposed between the first heat shrinkable tube 30 and the second heat shrinkable tube 50, one end of the first conductive sheet 70 is connected to the negative electrode region 13, and the other end is connected to the protection plate positive electrode 21. One end of the second conductive sheet 80 is connected to the positive electrode region 12, and the other end is connected to the protective plate negative electrode 22. In this way, when the first conductive wire 23 led from the protective plate positive electrode 21 and the second conductive wire 24 led from the protective plate negative electrode 22 are connected to an external circuit and form a loop, the battery main body 10 can supply power to the outside through the battery protective plate 20.
In the embodiment of the present invention, in order to avoid the short circuit of the battery protection plate 20, the first insulating sheet 40 is further disposed on the protection plate anode 21 and the protection plate cathode 22, the first insulating sheet 40 can be a sealing insulating sheet capable of being pasted, and can be pasted on the protection plate anode 21 and the protection plate cathode 22, because the protection plate anode 21 and the protection plate cathode 22 have a thickness, therefore, a certain space is reserved between the first insulating sheet 40 and the other side of the battery protection plate 20.
In the embodiment of the present invention, since the housing 11, the positive electrode region 12, the negative electrode region 13 and the battery protection plate 20 of the battery main body 10 all include metal materials, it is known that the metal materials may have material property changes (e.g., embroidered) when contacting water, thereby possibly causing the battery main body 10 to generate electric leakage. In addition, if the positive electrode region 12, the negative electrode region 13 or the battery protection plate 20 comes into contact with water, there is a possibility that a short circuit may occur, and thus it is important to design the battery main body 10 and the battery protection plate 20 to be waterproof.
In the embodiment of the present invention, in order to prevent water, the waterproof battery 200 firstly wraps the first heat shrinkable tube 30 on the housing 11, where the coverage area of the first heat shrinkable tube 30 is the whole area of the housing 11, and may slightly extend to the positive electrode region 12 and the negative electrode region 13 at the positions of both ends. The first heat shrinkable tube 30 may be made of PVC, PE, PVDF, PTFE, EPDM, silicone rubber, fluororubber, or the like, and has a high-temperature shrinkage characteristic, that is, after the first heat shrinkable tube 30 is wrapped around the housing 11, the first heat shrinkable tube 30 is shrunk by heating the first heat shrinkable tube 30, and is tightly attached to the housing 11.
In the embodiment of the present invention, further, the waterproof battery 200 further wraps the second heat shrinkable tube 50 outside the first heat shrinkable tube 30, wherein the second heat shrinkable tube 50 covers the first heat shrinkable tube 30 and extends to the edge of the first insulation sheet 40, so as to fix the first insulation sheet 40, thereby preventing the first insulation sheet 40 from falling off.
In the embodiment of the present invention, as described above, since the first and second heat shrinkable tubes 30 and 50 only function as a wrapping and do not form a complete seal, on one hand, there may be gaps at the connection between the second heat shrinkable tube 50 and the first insulating sheet 40 (for example, at a temperature of 100 degrees celsius, after the second heat shrinkable tube 50 shrinks, there may be gaps of 0.1mm to 0.2mm at the connection between the second heat shrinkable tube 50 and the first insulating sheet 40), and moisture may contact the battery main body 10 through these gaps; on the other hand, the first insulating sheet 40 serves as an insulator and cannot be completely waterproof, and moisture may penetrate through the first insulating sheet 40 and come into contact with the battery protection plate 20 to cause a short circuit of the battery protection plate 20.
For this reason, in the embodiment of the present invention, the first silicone layer 60 is further coated on the area of the first insulating sheet 40 not covered by the second heat shrinkable tube 50. The first silicone layer 60 may be made of epoxy resin or high molecular weight resin, which has a waterproof function, so as to prevent moisture from permeating. In addition, the first silicone gel layer 60 is gel-like before being solidified, so that a gap between the connection portions of the second heat shrinkable tube 50 and the first insulating sheet 40 can be filled, and moisture is prevented from penetrating through the gap and contacting the battery body 10. In this manner, a completely water-tight seal is achieved at the positive electrode region 12.
It should be noted that, in the embodiment of the present invention, a second insulating sheet 90 is attached to a surface of the battery protection plate 20 facing the positive electrode region 12, and the second insulating sheet 90 can avoid abrasion or short circuit caused by direct contact between the positive electrode region 12 and the battery protection plate 20.
