[0022] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5As shown, the utility model discloses a magnetic connector, including a base body 1 and a connecting head 2, the connecting head 2 includes a base 21 and a connecting portion 22 arranged on the upper part of the base 21, the lower part of the base body 1 is provided with a accommodating cavity 11 that can accommodate the base 21, and the top of the base body 1 is penetrated by a avoidance opening 12 that is connected to the accommodating cavity 11 and for the connecting portion 22 to extend out, the lower part of the base 21 or the lower part of the base body 1 is provided with a magnetic component 3, and the upper surface of the base 21 is bonded to the inner top surface of the accommodating cavity 11.

[0024] The base 1 serves as the basic part of the magnetic connector, and the device and the magnetic connector are quickly connected through the connector 2. In the embodiment, the base 1 is made of aluminum alloy and is anodized to improve the appearance quality of the product. The base 21 of the connector 2 matches the accommodating cavity 11 of the base 1, and the accommodating cavity 11 provides installation space for the base 21. The avoidance opening 12 provided through the top of the base 1 allows the connecting part 22 to extend from the accommodating cavity 11, so that the connecting part 22 can be connected to the device. At the same time, the setting of the avoidance opening 12 and the connecting part 22 allows the base 1 to be tightly combined with the connector 2, thereby enhancing the overall visual effect of the product. A magnetic component 3 is provided at the lower part of the base 21 or the lower part of the base 1, and the magnetic component is adsorbed by the magnetic component 3 to achieve the effect of quickly connecting the device and the magnetic component. The upper surface of the base 21 is bonded to the inner top surface of the accommodating cavity 11, which effectively prevents the base 21 from rotating relative to the base 1 and improves the stability of the overall structure.

[0025] Compared to directly bonding the connector 2 to the base 1, the arrangement of the base 21 and the accommodating cavity 11 can increase the contact area between the two without affecting the appearance, thereby reducing externally visible bonding marks. When the connector 2 is directly bonded to the base 1, when a tensile force is applied to the base 1, the force between the connector 2 and the base 1 is mainly manifested as a peeling force that separates the bonding surfaces, which can easily lead to bonding failure. When the upper surface of the base 21 is bonded to the inner top surface of the accommodating cavity 11, when a tensile force is applied to the base 1, the force exerted on the upper surface of the base 21 and the inner top surface of the accommodating cavity 11 is mainly manifested as a positive pressure that helps to enhance the contact tightness of the bonding surfaces, thereby enhancing the stability and reliability of the connection.

[0026] Compared with the traditional screw fixing method, the setting of bonding the upper surface of the base 21 to the inner top surface of the accommodating cavity 11 simplifies the assembly process and improves production efficiency. At the same time, it can effectively prevent relative rotation between the base 21 and the base body 1, thereby improving the stability of the overall structure.

[0027] A first annular mounting groove 211 is formed downwardly at the lower portion of the base 21 , and the magnetic element 3 is disposed in the first mounting groove 211 .

[0028] The annular first installation groove 211 ensures that the magnetic component 3 is accurately installed in the base 21, avoids position deviation, and improves the stability of the connection.

[0029] In the embodiment, the annular first mounting groove 211 is provided on the side wall of the lower portion of the base 21 , so that the first mounting groove 211 has a larger diameter, thereby ensuring that the magnetic attraction component 3 can cover a larger magnetic attraction surface.

[0030] The magnetic member 3 is bonded to the upper surface of the first mounting groove 211 .

[0031] The magnetic member 3 is bonded to the upper surface of the first mounting groove 211 to ensure stability and reliability of the magnetic member 3 in the base 21 .

[0032] In the embodiment, the magnetic attraction member 3 includes a mounting ring, a lower portion of which is provided with a plurality of magnetic blocks equidistantly arranged around the mounting ring, and an upper surface of the mounting ring is bonded to an upper surface of the first mounting groove 211 .

[0033] A cover plate 4 capable of covering the magnetic element 3 is provided at the lower portion of the base body 1 .

[0034] The cover plate 4 can further protect the magnetic component 3, preventing the magnetic component 3 from being affected by external physical damage and environmental factors, while improving the overall aesthetics of the product.

[0035] The lower part of the seat body 1 is downwardly opened with a second mounting groove 13 around the accommodating cavity 11. The lower surface of the base 21 is higher than or flush with the upper surface of the second mounting groove 13. The upper surface of the cover plate 4 is bonded to the upper surface of the second mounting groove 13.

[0036] The second mounting groove 13 provides a fixed mounting space for the cover plate 4, ensuring that it can be securely installed on the lower portion of the base 1. The lower surface of the base 21 is higher than or flush with the upper surface of the second mounting groove 13, ensuring that the cover plate 4 does not interfere with the base 21 during installation, thereby ensuring that the cover plate 4 can be smoothly installed. The upper surface of the cover plate 4 is bonded to the upper surface of the second mounting groove 13, ensuring the stability and reliability of the cover plate 4 in its position.

[0037] In the embodiment, the upper surface of the base 21 is bonded to the inner top surface of the accommodating cavity 11, the magnetic component 3 is bonded to the upper surface of the first mounting groove 211, and the upper surface of the cover plate 4 is bonded to the upper surface of the second mounting groove 13. The bonding method adopted is dry bonding through double-sided tape, without waiting for drying or curing; compared with wet bonding, the pasting position will not be affected by flow, which is conducive to precise positioning of bonding; there will be no overflow or infiltration into gaps during use, keeping the working environment clean.

[0038] The connecting portion 22 includes a mounting boss 221 . At least two elastic pieces 222 are circumferentially provided on the upper portion of the mounting boss 221 . The elastic pieces 222 are connected to locking sleeves 5 that can retract the elastic pieces 222 .

The free end of the elastic sheet 222 is retracted by the locking sleeve 5 to ensure that the elastic sheet 222 can be in close contact with the connecting part of the device, thereby providing reliable clamping force.

[0040] A limiting slot 2211 is defined on the upper portion of the mounting boss 221 .

[0041] By opening a limiting groove 2211 on the upper part of the mounting boss 221, the limiting protrusion corresponding to the connecting part of the device can be inserted into the limiting groove 2211, and the two cooperate to limit the relative rotation of the device and the magnetic connection part.

[0042] A first thread 2221 is formed on the outer periphery of the elastic piece 222 , and a second thread 51 matching with the first thread 2221 is formed on the inner wall of the locking sleeve 5 .

[0043] By providing the first thread 2221 and the second thread 51 , the user can achieve the connection between the locking sleeve 5 and the elastic piece 222 by screwing the locking sleeve 5 , which is convenient for assembly and disassembly.

[0044] A tightening portion 2222 is provided on the upper portion of the elastic sheet 222 , and a locking protruding ring 52 capable of pressing the tightening portion 2222 inward is provided on the inner wall of the upper portion of the locking sleeve 5 .

[0045] By configuring the locking protrusion 52 and the tightening portion 2222 , when the locking sleeve 5 moves toward the fixed end of the elastic sheet 222 , the locking protrusion 52 can press the tightening portion 2222 inward, thereby further enhancing the clamping force of the elastic sheet 222 .

[0046] The outer periphery of the locking sleeve 5 is provided with a screwing protrusion 53 for facilitating screwing of the locking sleeve 5 .
