Double-faced identification switching circuit applied to magnetic connector, and magnetic connector

Abstract

The invention discloses a double-faced identification switching circuit applied to a magnetic connector, and a magnetic connector. The double-faced identification switching circuit applied to a magnetic connector includes an input magnetic interface, an output magnetic interface, an identification control circuit and a switching circuit, wherein the input magnetic interface is provided with two direction signal pins for different levels; the output magnetic interface is adaptive to the input magnetic interface, and is provided with detection pins corresponding to the direction signal pins of the input magnetic interface; the identification control circuit is used for detecting the levels of the detection pins of the output magnetic interface so as to determine the connection state between the input magnetic interface and the output magnetic interface and generate a corresponding switching control signal; and the switching circuit is used for switching circuit connection of the magnetic connector according to the switching control signal. The double-faced identification switching circuit applied to a magnetic connector can solve the problem that a traditional magnetic connector has the advantages of being unstable in circuit, being low in efficiency, being high in cost, being complicated in circuit and being high in technological difficulty, can significantly improve the stability of circuit and the circuit switching efficiency, and can reduce the cost of product and the technical difficulty.

Description

technical field [0001] The invention relates to a magnetic connector and a double-sided identification switching circuit applied to the magnetic connector, in particular to the double-sided identification and circuit switching technology of the magnetic connector. Background technique [0002] At present, the electrical connection between electronic devices mainly depends on connectors. For example, mobile phones usually need to be plugged with power adapters, personal computers and other devices through connectors. In order to improve user experience, technicians designed magnetic connectors. An electrical connection device with an interface adapter is disclosed in the Chinese utility model patent application CN201520088692.X (application date: 2015.02.06; applicant: Shenzhen Heiyu Technology Co., Ltd.). Figure 13 of this application shows the mating state of the electrical connection device and the electronic device. The electrical connection device includes a T-shaped i...

Problems solved by technology

Most of the existing magnetic connectors on the market can only charge devices on both sides but cannot transmit data or charge on one side and transmit data on one side. Only a very small part can transmit data on both sides and charge on both sides. The identification method of the magnetic data cable is very complicated and not stable enough, and the current ones on the market are too large to be suitable for various accessories (such as: protective shells), and at the same time, the excessively large circuit size leads to insufficient magnetic force

Moreover, the current circuit cost is relatively high, causing the product itself to be too expensive
