[ detailed description ] embodiments

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The utility model provides a formula charge structure is inhaled to magnetism.

Referring to fig. 1 and 2, in an embodiment of the present invention, the magnetic charging structure includes a magnetic base 10 and a magnetic wire 20 magnetically attracted to the magnetic base 10.

Specifically, a pair of first ejector pins 11, a first magnet 12 and a second magnet 13 are arranged in the magnetic base 10, each first ejector pin 11 includes an ejector pin housing 111, and a first spring 112 and a core pin 113 which are arranged in the ejector pin housing 111, the bottom end of the ejector pin housing 111 penetrates through the magnetic base 10, the first spring 112 is located at the top of the ejector pin housing 111, the top of the core pin 113 is in contact with the first spring 112, and the bottom of the core pin 113 extends out of the ejector pin housing 111. The magnetic wire 20 includes a magnetic connector 21, a USB connector 22, and a conducting wire 23 connecting the magnetic connector 21 and the USB connector 22, a pair of second pins 211, a third magnet 212, and a fourth magnet 213 are disposed in the magnetic connector 21, and a second spring 214 is connected to a top of each second pin 211.

It can be understood that the magnetic base 10 is generally located on a housing of a product, and the pair of first pins 11 is used for electrically connecting with a circuit board of the product, and the first pins 11 and the second pins 211 are made of chemical gold, which is an alloy of copper, and has good electrical conductivity and is not easily oxidized. After the USB connector 22 of the magnetic wire 20 is connected to a charger or a PC, the magnetic connector 21 can be precisely connected to the magnetic base 10 disposed on the product housing by magnetic attraction, so that each first thimble 11 is electrically connected to the corresponding second thimble 211, and the second spring 214 can prevent poor contact and improve the stability of electrical connection.
