【detailed description】

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1 , the magnetic connector 10 includes a female connector 20 and a male connector 30 . The male connector 30 is magnetically coupled to the female connector 20 , and the male connector 30 is mated with the female connector 20 after the absorbing connection. Form an electrical connection. When it is desired to charge and/or transmit data to the electronic device using the magnetic connector 10, different male connectors 30 can be magnetically attracted and mated with the female connector 20 in order to accommodate different types of electronic devices.

Referring to FIGS. 2A-2B, the female connector 20 includes a tongue assembly 201, a first magnet 203, and a housing 205. The first magnet 203 is disposed on one side of the tongue assembly 201 and is housed in the housing 205 together with the tongue assembly 201. The first magnet 203 is magnetically attracted to the male connector 30 to connect the tongue assembly 201 to the male connector. The device 30 cooperates to form an electrical connection.

It can be understood that the first magnet 203 can be annular, sleeved around the tongue plate 2011, or can be semi-circular, rectangular, etc., connected to the side of the tongue assembly 201 that mates with the male connector 30, as long as it can The connector 30 is magnetically attracted, and the tongue assembly 201 can be mated with the male connector 30.

As an embodiment, the housing 205 may be integrally formed with the first magnet 203, or the housing 205 itself may be magnetic as long as it can be magnetically attracted to the male connector 30.

Specifically, when the first magnet 203 is housed in the housing 205 together with the tongue assembly 201, the first magnet 203 has a spacing H from one end of the housing 205 for magnetically adsorbing the male connector 30 and the first magnet 203. , the male connector 30 is accommodated. That is, when the male connector 30 needs to be mated with the female connector 20, the male connector 30 enters the housing 205 from the end of the housing 205 having the distance H from the first magnet 203, and is magnetically attracted to the first magnet 203, and The tongue assembly 201 cooperates to form an electrical connection, and at this time the male connector 30 is partially housed within the housing 205 for rapid positioning each time the male connector 30 mates with the female connector 20.

Further, when the first magnet 203 is housed in the housing 205 together with the tongue assembly 201, the tongue assembly 201 has a distance S from one end of the housing 205, that is, the tongue plate 2011 protrudes from the first magnet 203, and S≤ H.

It can be understood that the first magnet 203 and the housing 205 and/or one end of the tongue assembly 201 can also be flush, as long as the first magnet 203 can be magnetically attracted to the male connector 30, and the tongue assembly 201 can be connected to the male connector. 30 can form an electrical connection.

Referring to Figures 3A-3C, the tongue assembly 201 includes a tongue plate 2011, a contact terminal 2013, and a circuit board 2015. The contact terminal 2013 is disposed inside the tongue plate 2011 and electrically connected to the circuit board 2015. When the male connector 30 is engaged with the tongue plate assembly 201, the contact terminal 2013 contacts the male connector 30 to form an electrical connection, thereby forming a circuit board 2015. Electrical connection.

Specifically, the tongue plate 2011 is provided with a receiving space 2012 penetrating the tongue plate 2011, and the contact terminal 2013 is disposed on the inner wall of the receiving space 2012. When the male connector 30 is engaged with the tongue assembly 201, the male connector 30 partially enters the accommodating space 2012, and comes into contact with the contact terminal 2013 in the accommodating space 2012 to form an electrical connection.

Further, the contact terminals 2013 are arranged in two parallel rows on the inner walls of the opposite sides of the accommodating space 2012, and the order of the contact terminals 2013 of one row is GND, V+, D+, D, and the order of the other row is in contrast. The side of the contact terminal 2013 away from the male connector 30 is respectively connected to the opposite surfaces of the circuit board 2015 to form an electrical connection with the circuit board 2015.

Further, the contact terminal 2013 is a conductor having elasticity, and the end portion on the side away from the circuit board 2015 is bent away from the inner wall of the accommodating space 2012 to form a bent portion 2017. When the male connector 30 is engaged with the tongue assembly 201, the contact between the bent portion 2017 and the male connector 30 is elastic contact, that is, when the contact terminal 2013 is connected to the male connector 30, the male connector 30 is opposite to the two. The contact terminals 2013 on the side are pressed, so that the contact terminals 2013 on the opposite sides have an elastic force in the direction of the male connector 30, so that the connection is more stable and the contact effect is better.

It can be understood that one end of the contact terminal 2013 away from the bent portion 2017 is exposed to the receiving space 2012 to form an electrical connection with the circuit board 2015, so that the contact terminal 2013 has a sufficient length, so that a sufficient force arm can be formed at the bent portion 2017. After the tongue 3011 is inserted into the accommodating space 2012, the contact terminal 2013 can be sufficiently elastic to be in close contact with the tongue 3011.

The tongue has a thickness of 0.6-1.2 mm or 0.3-2.5 mm.

It can be understood that the distance between the opposite sides of the bent portions 2017 is smaller than the thickness B of the tongue piece 3011, so that when the tongue piece 3011 is inserted into the receiving space 2012, the contact terminal 2013 is pressed to contact the contact terminal 2013. The one side is subjected to a force, thereby causing an elastic deformation, which generates an elastic force toward the tongue piece 3011 to achieve elastic contact of the tongue piece 3011 with the contact terminal 2013. The contact terminal 2013 has a certain length, so that the contact terminal 2013 can be used as a "lever", thereby having a large clamping force, so that the contact terminal 2013 generates a large clamping force to the tongue 3011 to improve the stability of the connection. Alternatively, the length of the contact terminal 2013 is 5-10 mm, or 6-8 mm.

The end of the contact terminal 2013 away from the circuit board 2015 and the inner wall bracket of the accommodating space 2012 may not have a gap, and when pressed by the tongue piece 3011, plastic deformation is caused by the elasticity of the material itself. When the tongue piece 3011 is inserted into the accommodating space 2012, it may be in elastic contact with the contact terminal 2013.

It can be understood that the second magnet 303 may be annular, sleeved around the tongue 3011, or may be semi-circular, rectangular, or the like, and connected to the side of the connecting head 301 and the tongue assembly 201, as long as it can The male connector 30 is magnetically attracted, and the tongue 3011 can enter the accommodating space 2012 to be in contact with the contact terminal 2013.
