Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in the figure, provide green mould proof button lithium manganese dioxide battery, including protective frame 1, protective frame 1's inner chamber fixedly connected with evenly distributed's interlayer 2, elastic shield 3 is cup jointed to protective frame 1's top, and protective frame 1's inner chamber centre gripping has five button cell 4, and the middle part of button cell 4 top surface and bottom surface is fixedly connected with sheetmetal 5 respectively, and button cell 4's outside has cup jointed isolation layer 6. Button cell 4 self is the primary structure who realizes discharging, and isolation layer 6 in the outside can realize the protection to button cell 4 to protective frame 1 and elastic shield 3 can realize the secondary protection to button cell 4, reduce the influence that the external world produced button cell 4 self.

Fig. 1 is the structure schematic diagram of the utility model discloses a look before, button cell 4 is located the side of every interlayer 2, and the distance value between interlayer 2 is greater than button cell 4's thickness value. The interlayer 2 mainly separates the button cell 4 from the button cell 4, reduces the contact between the button cells 4, i.e., a certain button cell 4 mildews, and cannot influence other button cells 4. Meanwhile, the distance value between the interlayers 2 is constant, so that the button cell 4 can be tightly clamped in the protective frame 1.

In this embodiment, the isolation layer 6 is sleeved on the surface of the button cell 4, circular grooves are respectively formed in the upper side and the lower side of the isolation layer 6, and the metal sheet 5 penetrates through the circular grooves and is connected with the button cell 4. Through the design of adopting isolation layer 6 to wrap up button cell 4 for isolation layer 6 can wrap up button cell 4 completely, reduces external influence to button cell 4. Meanwhile, the discharge of the button cell 4 is realized through the metal sheet 5, and the protection of the button cell 4 is ensured on the basis of not influencing the use.

As shown in fig. 1, the lower portion of the elastic shield 3 is in a rolled shape, and the maximum length of the elastic shield 3 that can be stretched is greater than the length of the protection frame 1. After the button cell 4 is clamped in the protective frame 1, the elastic shield 3 can be utilized to sleeve the protective frame 1 integrally, so that the protective effect on the button cell 4 is realized, the length value which can be stretched by the elastic shield 3 is certain, and the protective frame 1 can be completely rolled up integrally.

It should be noted that the periphery of the protective frame 1 and the right side of the interlayer 2 are respectively smooth curved surfaces. Because elasticity guard shield 3 cup joints at the protective frame 1 outside, through the design with the adoption smooth curved surface in the protective frame 1 and the interlayer 2 outside, can prevent that protective frame 1 and interlayer 2 from causing the damage to elasticity guard shield 3 because the edge is too sharp-pointed.

The utility model discloses a theory of operation and use flow: before using, at first place button cell 4 in protective frame 1 for button cell 4 can be fixed by the inseparable centre gripping of protective frame 1 and interlayer 2, and after button cell 4 placed and finishes, drags outside elasticity guard shield 3 downwards, and at this moment elasticity guard shield 3 can overlap protective frame 1, thereby has realized the sealed effect of preserving to button cell 4.

When button cell 4 uses, take out button cell 4 from protection frame 1 to after the button cell 4 installation finishes, the sheetmetal 5 of upper and lower both sides can realize electrically conductive effect, and isolation layer 6 in the outside can be inseparable with button cell 4 parcel, prevents that external moisture etc. from causing the erosion to the battery, also can reduce button cell 4 self and appear the emergence of the circumstances such as mildenes and rot because the weeping.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
