Problems solved by technology

[0003] In the existing button batteries, generally after the upper case and the lower case are assembled, a sealing ring needs to be provided in the gap between the upper case and the lower case, so that the upper case can be stably embedded in the lower case. In the body, and in order to make the sealing better, it is also possible to inject glue on the button battery with the assembled sealing ring. This method greatly increases the difficulty of button battery assembly, the process is more complicated, and the assembly process is increased. The time cost reduces the efficiency of assembly

Embodiment Construction

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses a button battery, which comprises a battery upper shell, a battery bottom shell and a battery inner core, wherein the battery inner core is accommodated in the battery upper shell, the battery upper shell is buckled on the battery bottom shell, the battery upper shell comprises a negative electrode steel sheet and an insulating ring body, and the insulating ring body is arranged on the negative electrode steel sheet. According to the button battery disclosed by the invention, the structure of the upper battery shell is changed into the combination of the plastic side edge and the negative electrode steel sheet, and compared with the existing button battery, the process operation of injection molding on the side wall of the shell can be omitted, so that the effects of easiness in assembly, assembly step saving and insulativity improvement can be effectively realized.

Description

technical field [0001] The invention relates to the field of button batteries, in particular to a button battery. Background technique [0002] There are several common button batteries according to their chemical composition: carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable button batteries, nickel-metal hydride rechargeable button batteries, etc. According to the shape, there is a distinction between monomer and stack. In detail, carbon button batteries are the most common and cheapest. Alkaline batteries are a little more expensive, but they have a good discharge effect. Both voltages are 1.5V and range from Alkaline AG1 to AG13, with nominal capacities ranging from approximately 15mAh to 140mAh. Suitable for micro-ampere discharge requirements. It is mostly used in calculators, electronic toys, hearing aids, lighters, watches and so on. In addition to being powered by a single battery, the button battery has also d...
