technical field

The utility model relates to the field of electronics, in particular to a three-contact contact charging assembly.

Background technique

With the development of electronic technology, consumer electronic products have spread to people's lives at a very fast speed, such as small electrical products such as mobile phones, digital cameras, PDAs, notebook computers and MP3 players. Similar electrical products must not only be light, thin, and small, but also portable, and batteries must be used to use them. In response to environmental protection, rechargeable batteries have been widely introduced into use. Commonly used rechargeable batteries are nickel-cadmium batteries, nickel-metal hydride batteries and lithium batteries, and these rechargeable batteries all need a charging device to charge them.

When a traditional charging device charges a battery inside an electrical appliance, the output terminal and the input terminal need to be connected to each other to realize power transmission. As far as electrical equipment using DC power is concerned, the charging device needs to convert the AC power of the mains to DC through a rectifier before it can be used by electrical equipment using DC power; but the DC power has positive and negative poles. In use, it is necessary to connect the correct polarity to ensure the supply of DC power. Not only is it not convenient to use, but once the polarity is connected incorrectly, it is more likely to cause damage to electrical equipment. Therefore, contact-type electric energy conduction components regardless of positive and negative poles emerged at the historic moment. The contact end surface of the charging connecting piece of a general contact electric energy conducting component has four contacts, so that no matter how the charging connecting piece is placed on the power supply board, among them The two contacts can be respectively connected to the positive and negative poles on the power supply board to ensure that the power supply board can charge the load 100% through the charging connection piece. However, the design and manufacturing process of four contacts is relatively complicated and the cost is high.

Therefore, there is an urgent need for a three-contact contact charging assembly with relatively simple manufacturing process and low cost.

Utility model content

The purpose of the utility model is to provide a three-contact contact charging assembly with relatively simple manufacturing process and low cost.

In order to achieve the above purpose, the technical solution of the utility model is to provide a three-contact contact type charging assembly, including a power supply board and a charging connecting piece, and the power supply board includes a substrate, several positive pole pieces, several negative pole pieces and a power input part , the positive electrode sheet and the negative electrode sheet are arranged parallel to each other on the substrate, the positive electrode sheet and the negative electrode sheet are arranged alternately, the output end of the power input part is electrically connected to the positive electrode sheet and the negative electrode sheet connected, the input end of the power input part is electrically connected to the external power supply, the charging connection piece has an input end surface, and three contacts are arranged on the input end surface, and the diameter of the contact points is less than or equal to that of the adjacent positive pole The gap between the sheet and the negative electrode sheet, and the output end of the charging connection sheet is electrically connected to the load.

The input end of the power input part is a USB connector or a mains plug.
