Problems solved by technology

However, this method has problems such as complicated packaging process, high cost, and difficulty in controlling the final shape of the battery packaging product.
This severely restricts the promotion and replacement of secondary batteries in many application fields of primary batteries.
[0005] In addition, the use of secondary batteries must be equipped with independent dedicated chargers, and mixed use of chargers may easily lead to safety accidents
It is not convenient to carry and use the charger

Abstract

The invention provides a constant-voltage protection structural member with a USB interface. The constant-voltage protection structural member comprises an output terminal, a sleeve, a PCB and a supporting base, wherein the PCB is arranged in the sleeve; the output terminal is arranged on the top of the sleeve; and the supporting base is arranged at the bottom of the sleeve. The invention also provides a secondary battery of which the constant-voltage protection structural member with the USB interface provided by the invention is embedded in the opening end of a shell in a matched manner. The secondary battery provided by the invention is novel in structure and convenient to manufacture, the secondary battery can be charged directly without an external charger, and voltage output can be restricted according to requirements, so that the market requirement is met.

Description

technical field [0001] The invention relates to a constant voltage protection structural component and a battery, in particular to a constant voltage protection structural component with a USB interface and a secondary battery using the same. Background technique [0002] With the development of secondary battery technology, the performance of secondary batteries has been rapidly improved, and its cost has also been greatly reduced, especially the high energy density and recyclable characteristics of secondary batteries, so it has been increasingly The wider the application. For example, rechargeable lithium-ion batteries in secondary batteries have become the main power supply batteries for mobile phones, notebook computers, and cameras, and in many traditional application fields of primary batteries such as remote controls, flashlights, toys, etc., secondary batteries are gradually becoming more and more popular. Primary battery replacement. [0003] However, compared wi...
