Novel positive and negative electrode component applied to button cell and braid used by same

Abstract

The invention discloses a novel positive and negative electrode component applied to button cell and a braid used by the same. The component comprises a positive electrode metal plate and a negative electrode metal plate; one end of the positive electrode metal plate is a positive electrode fitting plate body end, the other end of the positive electrode metal plate is an integrated contact end that is perpendicular to the positive electrode fitting plate body end, the inner side of the contact end is contacted with the side part of the button cell, and first contact plates contacted with the top of the button cell are arranged on both two sides of the top of the contact end; one end of the negative metal plate is an annular end, the other end of the negative metal plate is a negative fitting plate body end integrated with the annular end, and at least two second elastic contact plates connected with the bottom part of the button cell are arranged in the annular end. Both the positive electrode fitting plate body end and the negative plate fitting plate body end are electrically connected with an electronic circuit board via a soldering paste layer, the phenomena of short circuit orbattery separation are avoided; the connection between the electronic circuit boards is firm, the structure is simple, the braid can be used for automatically processing, the manual operation is reduced, the production efficiency is improved, the braid structure is changed, and the situation of throwing material is avoided.

Description

technical field [0001] The invention relates to a connection device of a button battery, in particular to a novel positive and negative electrode assembly for the button battery and the used braiding tape. Background technique [0002] Today's button batteries are arranged between the positive and negative electrodes by snapping. Since the metal sheet of the positive or negative electrode is required to completely fix the button battery, the structure of at least one of the positive or negative metal sheets is relatively complicated. It adopts a specific independent package, and one or several workers are required to arrange the positive metal sheet and the negative metal sheet in one direction during installation, and then another worker will place the positive metal sheet and the negative metal sheet in the electronic circuit, which is costly. When there is a work delay, automatic production cannot be realized, which leads to a slow process of installing the positive and n...

[0002] Today's button batteries are arranged between the positive and negative electrodes by snapping. Since the metal sheet of the positive or negative electrode is required to completely fix the button battery, the structure of at least one of the positive or negative metal sheets is relatively complicated. It adopts a specific independent package, and one or several workers are required to arrange the positive metal sheet and the negative metal sheet in one direction during installation, and then another worker will place the positive metal sheet and the negative metal sheet in the electronic circuit, which is costly. When there is a work delay, automatic production cannot be realized, which leads to a slow process of installing the positive and negative connecting pieces, and the error rate of installation is often increased due to the fatigue of the operator, which seriously affects the production efficiency. Among them, the current positive metal The metal sheet and the negative metal sheet are fixed on the electronic circuit board by welding, and there are often cases of false welding or loosening

[0003] In order to solve the above problems, our company has developed and applied for a Chinese utility model patent with the application number ZL201721521436.0, which specifically discloses a new type of positive and negative electrode assemblies for button batteries and the braiding used, although it solves the above problems However, there are still the following problems: First, the button battery is not fixed firmly, and it often jumps up due to vibration. In severe cases, a short circuit or battery separation will occur, which affects the use of electrical appliances by users. Second, the negative braid will block the suction head Suction the negative electrode metal sheet, the suction head cannot firmly absorb the negative electrode metal sheet, which will cause material throwing
