Button battery positive electrode spring piece for remote control key and button battery mounting structure

Abstract

The invention relates to a button battery positive electrode spring piece for a remote control key and a button battery mounting structure. A first welding portion is provided with an SMT suction nozzle surface; the positive electrode spring piece can be directly placed on a circuit board through the suction nozzle surface of the positive electrode spring piece; at the same time, a welding surfaceis disposed, and can be fixedly attached to the circuit board together with other electronic components to realize automatic mounting production, thereby solving the problems of only manual press mounting and low production efficiency. An elastic support portion is supported by limiting portions, the overall shape variable of the elastic support portion is restricted, and the poor contact of welding spots caused by excessive deformation of the elastic support portion is prevented, thereby improving the work stability. In order to further improve the working stability of the positive electrodespring piece, in the button battery mounting structure, a blocking mechanism is adopted to further restrict the overall shape variable of the elastic support portion, and prevent the poor contact ofthe welding spots caused by the excessive deformation of the elastic support portion. A quick release cover is disposed to facilitate the replacement operation of the battery, and prevent the situations of loosening, falling off and the like easily caused by multiple disassembly and assembly.

Description

technical field [0001] The invention relates to a mechanism structure for battery installation, and more specifically, relates to a button battery positive shrapnel for a remote control key that facilitates automatic placement, and a button battery installation structure for a remote control key. Background technique [0002] For the device using the button battery, due to the special structure of the button battery itself, the installation stability of the button battery is relatively poor. That is, the overall deformation of the product parts (positive shrapnel) is large, the fixing strength is insufficient, and it is easy to loosen and fall off when dropped, vibrated, and stressed. [0003] For infrequently moving devices, such as scales, this deficiency will not have a great impact on use, but for portable devices, such as car remote keys, this deficiency will seriously affect the user experience. In order to overcome this shortcoming, a common solution is to give prior...

AI Technical Summary

Problems solved by technology

The fixed part is firm, and there is a problem of loose fit between the positive shrapnel and the groove of the base, and the upper claw is easily deformed. After deformation, it is easy to have poor contact with the PCB board, resulting in failure
