[0002] A magnetic connector, also known as a magnet connector, a magnetic force connector, and a magnetic connector, is one of the connectors widely used in electronic devices.

It realizes connection through magnetic adsorption and has the advantages of convenient and efficient replacement of different interface modules. However, when replacing the interface module of the existing magnetic connector with a replaceable interface, the interface on the magnetic seat will be exposed during the period of replacing the interface module, lacking the function of protecting it, so that external dust is easily introduced into the interface, affecting subsequent use.

[0021] In the figure: 1 magnetic attraction base, 2 interface module, Specific embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Refer to Figures 1 to 4 , a magnetic connector with a replaceable interface, comprising:

[0024] A magnetic base 1 and an interface module 2. A plurality of ear plates 6 are fixedly installed on the side of the magnetic base 1. Each ear plate 6 is provided with a mounting hole on its surface. By passing an external screw or rivet through the mounting hole on the ear plate 6, the magnetic base 1 can be installed at the required position. A rubber sealing ring 15 is fixedly installed on the surface of the magnetic base 1, and the rubber sealing ring 15 is in contact with the interface module 2, which can increase the sealing performance between the adsorption parts of the magnetic base 1 and the interface module 2 when they are adsorbed.

[0025] Moreover, the magnetic base 1 and the interface module 2 are connected by a magnetic component; the magnetic component includes a plurality of first magnetic blocks 8 fixedly embedded on the surface of the magnetic base 1. Each first magnetic block 8 adsorbs a second magnetic block 9 on its surface, and the second magnetic block 9 is fixedly installed on the surface of the interface module 2. The number of the first magnetic blocks 8 and the second magnetic blocks 9 is three and they are distributed in a circumferential array. By using the magnetic attraction force between each first magnetic block 8 and the second magnetic block 9, the quick connection between the magnetic base 1 and the interface module 2 can be realized, so that the user can conveniently detach the interface module 2 from the magnetic base 1 and replace it with different types of interface modules 2 according to actual needs, such as USB interfaces, HDMI interfaces, power interfaces, etc.

[0026] A connection cavity 3 is opened in the magnetic base 1. Two electrical connection columns 4 are fixedly installed in the connection cavity 3. The outer walls of the two electrical connection columns 4 are movably sleeved with electrical connection cylinders 7, and the electrical connection cylinders 7 are electrically connected to the corresponding electrical connection columns 4. Each electrical connection cylinder 7 movably penetrates through the end of the connection cavity 3 and is fixedly installed with the interface module 2. Through the contact connection between the two electrical connection columns 4 and the two electrical connection cylinders 7 respectively, electrical connection can be realized, so as to complete the transmission of power or data. Here, the two electrical connection columns 4 on the magnetic base 1 can be electrically connected to an external main device that needs to transmit data. This part is the prior art in the public domain, and this technical solution will not be elaborated in detail.

[0027] The protection component includes a protection frame 5 fixedly penetrating through the surface of the magnetic attraction seat 1 and extending into the connection cavity 3. One side of the protection frame 5 located inside the connection cavity 3 is in contact with a protection plate 10. A notch is formed on the side of the protection plate 10, and a fixed shaft 11 is rotatably installed in the notch. A fixed frame 12 is fixedly sleeved on the outer wall of the fixed shaft 11. Torsion springs 13 are fixedly connected between both sides of the fixed frame 12 and the ends of the notch. When connecting the interface module 2 to the magnetic attraction seat 1 and inserting the electrical connection cylinder 7 through the protection frame 5 into the connection cavity 3, the electrical connection cylinder 7 will first contact the protection plate 10 and push it to rotate clockwise around the fixed shaft 11, causing the two torsion springs 13 to generate deformation forces. After the electrical connection cylinder 7 is inserted onto the electrical connection post 4, the end of the protection plate 10 will always contact the nearest electrical connection cylinder 7 under the action of the two torsion springs 13. Then, when it is necessary to replace the interface module 2, the interface module 2 is pulled outwards. When the two electrical connection cylinders 7 are moved out of the protection frame 5, the protection plate 10 will quickly rotate counterclockwise and reset under the action of the two torsion springs 13 until it fits with the end of the protection frame 5 and seals it, so as to play a role in dust protection for the two electrical connection posts 4 in the connection cavity 3 during the period from taking out the interface module 2 to replacing the interface module 2, preventing external dust from entering the magnetic attraction seat 1 and adhering to the surface of the electrical connection posts 4, thereby ensuring the stable transmission of electricity or data between the magnetic attraction seat 1 and the interface module 2.

[0028] Further, two positioning blocks 14 are fixedly installed in the protection frame 5, and the two positioning blocks 14 are respectively movably sleeved on the surfaces of the two electrical connection cylinders 7. When inserting the electrical connection cylinders 7 into the connection cavity 3 to connect with the two electrical connection posts 4, they can respectively pass through the two positioning blocks 14 to ensure the precise alignment of the two electrical connection posts 4 and the two electrical connection cylinders 7 and achieve stable electrical connection. At the same time, it can also ensure the precise alignment of each first magnet 8 and the corresponding second magnet 9 to achieve the quick adsorption connection between the magnetic attraction seat 1 and the interface module 2.

[0029] Further explanation, unless otherwise clearly specified and limited, the above fixed connection should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
