Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

Referring to fig. 1 and 2, in an embodiment, a battery electrode structure is disclosed, which includes a casing 10 of a battery, and an elastic conductive sheet partially embedded in the casing 10 and partially exposed from the casing 10. The battery case 10 in the drawings is only a partial case at the electrode, and the technical point of the present solution lies in the design at the electrode, so the rest of the structure is not described herein, such as the battery body in the case. The electrodes are generally used for electrically connecting the batteries with other electronic components to be powered, and most batteries also have the problems of being detachable and repeatedly assembled for use, so that the requirement on the connection performance of the electrodes is high. The battery electrode structure in this embodiment has abandoned traditional spring and the structure of electrode thimble, and adopts electrically conductive flexure strip, and electrically conductive flexure strip is equivalent to the wire, guarantees the effective circulation of electric energy, has improved electrode electric connection's reliability greatly.

In view of the waterproof property of the electrode, referring to fig. 2 again, in a specific embodiment, a sealing member 40 is disposed between the housing 10 and the conductive sheet to seal the gap between the housing 10 and the conductive sheet, so as to prevent fluid outside the housing 10 from penetrating into the housing 10 from the gap. Because the conducting strip is partially located in the casing 10 and partially located outside the casing 10, a gap is easily formed at the contact position of the conducting strip and the casing 10, and in order to ensure the waterproof effect of the electrode, the sealing element 40 can be used for sealing the corresponding gap, thereby achieving the waterproof effect of the electrode. Also, the sealing member 40 may preferably be a silicone member. For example, a dispensing process may be preferably adopted, and liquid silicone is used to dispense from the inner side of the housing 10 to seal the corresponding gap.

In view of the convenience and stability of the battery, in a specific embodiment, with reference to fig. 1 to 3, the conductive sheet includes an embedded section 211 and a bent section 212 integrally connected, the embedded section 211 is located inside the casing 10, and the bent section 212 is located outside the casing 10 and is in a bent state. Thus, by utilizing the elastic bending performance of the elastic conductive sheet, during installation, the bending section 212 is further bent and is electrically connected with the powered element tightly, thereby ensuring the stability thereof.

In addition, in order to further make the electrode have sufficient elastic space, the adaptability is increased. Referring to fig. 1 and 2, in an embodiment, a gasket 30 is further disposed outside the housing 10, and the bent portion 212 of the conductive sheet partially or completely overhangs the gasket 30. When the battery is installed and used, the bending section 212 is further bent and is in contact with the gasket 30, the gasket 30 can provide effective protection for the conducting strip, the number of times that the conducting strip is bent after being repeatedly installed and used can be enhanced, and the stability of electric connection is guaranteed. Here, the gasket 30 may be a silicone gasket.

Referring again to fig. 1, in a specific embodiment, the conductive sheet includes a positive plate 22 and a negative plate 21 separated from each other, and the positive plate 22 and the negative plate 21 are disposed around the edge of the gasket 30. Further, the conductive sheet may preferably be a copper sheet in consideration of electrical connectivity of the electrodes and the requirement for repeated use.

Here, the upper, lower, left, right, front, and rear represent only relative positions thereof and do not represent absolute positions thereof. The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that the contents of the specification and the drawings are used for conversion, or directly or indirectly applied to other related technical fields, are included in the same way in the patent protection scope of the present invention.
