Description

Technical Field

[0001] This utility model belongs to the field of button cell technology, and particularly relates to a terminal structure and a button cell. Background Technology

[0002] Button cells are a common type of rechargeable battery. In actual use, the positive electrode post and the negative electrode stainless steel sheet have opposite polarities. The positive electrode post is mostly made of aluminum, and in order to ensure a certain degree of stamping plasticity, the aluminum material has less metal doping, resulting in insufficient hardness and strength of the post itself. When external components are attached to the aluminum post located in the center for charging and discharging for a long time, the aluminum post is under pressure. Due to the insufficient resistance of the aluminum post, it is prone to collapse and deformation, affecting the charging and discharging contact performance. In severe cases, it can lead to cracking of the aluminum post, resulting in safety risks such as leakage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a terminal structure and a button cell to address the problem that existing terminals are prone to collapse and deformation.

[0004] To address the aforementioned problems, this utility model provides a pole structure, comprising a pole body, a connecting plate, and a reinforcing plate. The pole body is connected to the lower surface of the connecting plate, and the reinforcing plate is disposed inside the connecting plate to enhance the strength of the connecting plate.

[0005] As a further improvement to the above technical solution:

[0006] Optionally, the reinforcing plate has a conductive hole, and the connecting plate located on the upper side of the reinforcing plate and the connecting plate located on the lower side of the reinforcing plate are electrically connected through the conductive hole.

[0007] Optionally, the conductive hole is annular.

[0008] Optionally, the width c of the conductive hole is 0.5 mm to 2 mm.

[0012] Optionally, the thickness e of the connecting plate located below the reinforcing plate is 0.05 mm to 0.1 mm.

[0013] Optionally, the distance d from the outer edge of the reinforcing plate to the outer edge of the connecting plate is 0.5 mm to 1.5 mm.

[0014] On the other hand, this utility model embodiment provides a button cell, including a cover plate, a housing, a core, and a terminal post structure as described above. The cover plate has a through hole, the post is inserted through the through hole, and the cover plate is insulated from the terminal post structure. The core is installed inside the housing, the cover plate is installed at the opening of the housing and is electrically connected to the housing, one pole of the core is electrically connected to the post, and the other pole of the core is electrically connected to the housing.

[0015] The electrode post structure and button cell provided in this embodiment of the utility model have at least the following beneficial effects compared with the prior art: In this electrode post structure, since the connecting plate is provided with a reinforcing plate inside, the reinforcing plate can strengthen the strength of the connecting plate.

[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 2 As shown, an embodiment of the present invention provides a pole post structure, which includes a pole body 131, a connecting plate 132 and a reinforcing plate 133. The pole body 131 is connected to the lower surface of the connecting plate 132, and the reinforcing plate 133 is disposed inside the connecting plate 132. The reinforcing plate 133 is used to strengthen the strength of the connecting plate 132.

[0025] In the electrode post structure provided in one embodiment of this utility model, since the connecting plate 132 is provided with a reinforcing plate 133, the reinforcing plate 133 can strengthen the strength of the connecting plate 132. When external components are fastened to the aluminum electrode post 130 for a long time for charging and discharging, the connecting plate 132 reinforced by the reinforcing plate 133 can reduce the probability of the electrode post 130 collapsing and deforming compared with the existing technical solutions. At the same time, it reduces the probability of the electrode post 130 cracking and leaking, which poses a safety risk.

[0026] The electrode post structure can mate with the cover plate 140. The cover plate 140 has a through hole 141, through which the post 131 passes, and the cover plate 140 and the electrode post structure are insulated from each other. When it is necessary to connect a charging or discharging element or device, one pole of the charging or discharging element or device is snapped onto the connecting plate 132, and the other pole is connected to the cover plate 140. In this embodiment, the electrode post 130 is the positive pole of the battery cell, and the cover plate 140 is the negative pole of the battery cell. The electrode post 130 is made of aluminum, and the cover plate 140 is made of stainless steel.

[0027] In another embodiment, the terminal 130 is the negative electrode of the battery cell, and the cover plate 140 is the positive electrode of the battery cell.

[0028] In one specific embodiment, the reinforcing plate 133 is a titanium alloy plate. For example... Figure 2 As shown, the reinforcing plate 133 has a conductive hole 134. The connecting plate 132 located on the upper side of the reinforcing plate 133 and the connecting plate 132 located on the lower side of the reinforcing plate 133 are electrically connected through the conductive hole 134. Since the titanium alloy plate has poor conductivity, the conductive hole 134 in the reinforcing plate 133, and the connecting plate 132 located on the upper side of the reinforcing plate 133 and the connecting plate 132 located on the lower side of the reinforcing plate 133 are electrically connected through the conductive hole 134, can enhance the conductivity between the connecting plate 132 located on the upper side of the reinforcing plate 133 and the connecting plate 132 located on the lower side of the reinforcing plate 133.

[0029] Of course, it is understandable that the reinforcing plate 133 can also be made of other high-strength materials, such as stainless steel, as long as it can strengthen the strength of the connecting plate 132, and there is no limitation here.

[0030] In this embodiment, as Figures 1 to 2 As shown, the conductive hole 134 is annular, and its width c is 0.5 mm to 2 mm. The thickness a of the reinforcing plate 133 is 0.05 mm to 0.15 mm, and it is completely covered by the edge of the connecting plate 132, with a thickness ratio of 1 / 5 to 1 / 3 of the total thickness b of the pole post 130. The thickness e of the connecting plate 132 located above the reinforcing plate 133 is 0.05 mm to 0.1 mm. The thickness e of the connecting plate 132 located below the reinforcing plate 133 is 0.05 mm to 0.1 mm. The distance d between the outer edge of the reinforcing plate 133 and the outer edge of the connecting plate 132 is 0.5 mm to 1.5 mm.

[0031] Of course, it is understandable that the conductive hole 134 can also be other shapes, such as circles; the thickness of the reinforcing plate 133 can also be other values, the thickness of the connecting plate 132 located on the upper side of the reinforcing plate 133 can also be other values, the thickness of the connecting plate 132 located on the lower side of the reinforcing plate 133 can also be other values, and the distance from the outer edge of the reinforcing plate 133 to the outer edge of the connecting plate 132 can also be other values, which are not limited here.

[0032] In addition, such as Figures 1 to 2 As shown, another embodiment of this utility model provides a button cell 100, which includes a cover plate 140, a housing 110, a core 120, and an electrode post structure as provided in any of the above embodiments. The cover plate 140 has a through hole 141, and the post 131 passes through the through hole 141. The cover plate 140 is insulated from the electrode post structure. The core 120 is installed inside the housing 110, and the cover plate 140 is installed at the opening of the housing 110 and electrically connected to the housing 110. One electrode of the core 120 is electrically connected to the post 131, and the other electrode of the core 120 is electrically connected to the housing 110. The specific structure of the electrode post structure is the same as described in the above embodiments. Since this button cell 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0033] In this embodiment, the positive electrode of the core 120 is electrically connected to the post 131, and the post 130 serves as the positive electrode of the button cell 100; the negative electrode of the core 120 is electrically connected to the housing 110, and the cover plate 140 serves as the negative electrode of the button cell 100. The upper surface of the cover plate 140 is insulated from the lower surface of the connecting plate 132 by an adhesive layer 150.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
