[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0031] refer to Figures 1 to 4According to an embodiment of the present invention, a magnetic connector capable of preventing a magnet 40 from falling off comprises a terminal 20, a rubber core 10 and a magnet 40. The terminal 20 is made of a conductive material, and an opening 410 is provided in the middle of the magnet 40; a boss 110 and a drawing groove 120 are provided on the end surface of one end of the rubber core 10, and a circle of protrusions 111 are provided on the side of the boss 110; the rubber core 10 is wrapped around the outside of the terminal 20, and one end of the terminal 20 exposes the boss 110; the magnet 40 is connected to one end of the rubber core 10 provided with the boss 110, and the boss 110 is inserted into the opening 410; the protrusion 111 is in contact with the inner wall of the magnet 40, and a glue storage gap 130 is formed between the side of the boss 110 and the inner wall of the magnet 40, and the glue storage gap 130 is connected to the drawing groove 120.

[0032] When the magnet 40 is adhered to the rubber core 10 by glue, the glue will fill the drawing groove 120 and the glue storage gap 130, and after solidification, a glue layer filling the glue storage gap 130 and the drawing groove 120 will be formed, thereby effectively improving the bonding strength between the magnet 40 and the rubber core 10, and at this time, a mutually fitting buckle will be formed between the glue layer and the boss 110, so the boss 110 will also be able to effectively prevent the magnet 40 from moving outward with the glue layer as a whole, thereby preventing the magnet 40 from falling off the rubber core 10.

[0033] Reference Figure 3 , Figure 4 In some embodiments of the present invention, the flower groove 120 is arranged perpendicular to the side of the boss 110, so that the glue can quickly pass through the flower groove 120 into the glue storage gap 130; specifically, the flower groove 120 is arranged perpendicular to the side corresponding to the long side of the boss 110, so that a larger number of flower grooves 120 can be set; and, specifically, the flower groove 120 extends from the edge of the end face of the glue core 10 to the side of the boss 110, so that glue can be injected or filled into the flower groove 120 and the glue storage gap 130 through the edge of the flower groove 120.

[0034] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the opening 410 is a waist-shaped hole, which can facilitate the arrangement of the terminal 20 in the magnet 40. Specifically, a plurality of terminals 20 are provided, and the terminals 20 are arranged in a row in the opening 410 along the direction of the opening 410.

[0035] In some embodiments of the present invention, both ends of the magnet 40 are configured as semicircular structures, and the semicircular structures at both ends of the opening 410 are eccentrically disposed inwardly relative to the two semicircular structures of the magnet 40. By eccentrically disposing the semicircular structure of the waist-shaped hole in the opening 410 inwardly, it is advantageous to increase the area of ​​the two ends of the magnet 40, and the two ends of the magnet 40 are the two magnetic poles of the magnet 40. Increasing the area of ​​these two ends is advantageous to improve the magnetic attraction of the magnet 40, thereby further ensuring the reliability of the interconnection between the magnetic connectors.

[0036] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, an elastic clamp 30 is further included. A positioning column 140 and a clamp installation groove 150 are provided at the bottom of the rubber core 10. The clamp installation groove 150 passes through the positioning column 140 and divides the positioning column 140 into two halves; the elastic clamp 30 is inserted into the clamp installation groove 150, and the elastic clamp 30 includes two elastic clamping arms 310. The elastic clamping arms 310 pass through the positioning column 140. A clamping block is provided at one end of the elastic clamping arm 310 passing through the positioning column 140, and the clamping block is provided on the side of the two elastic clamping arms 310 that are away from each other.

[0037] When connecting the circuit board, a connection hole is first set on the circuit board, and the positioning column 140 and the elastic clamping arm 310 can be inserted into the connection hole first. The magnetic connector can be positioned with the help of the positioning column 140 to facilitate the subsequent welding of the terminal 20 and the circuit board. After the elastic clamping arm 310 passes through the connection hole, the elastic clamping arms 310 will move away from each other under the action of their own elastic force, and the clamping block on the elastic clamping arm 310 can limit the elastic clamping arm 310 from escaping from the connection hole; and the elastic clamping arm 310 and the positioning column 140 are at the same position and can share the same connection hole on the circuit board, thereby reducing the space occupied on the circuit board and reducing the number of openings on the circuit board; with the help of the connection between the positioning column 140 and the elastic clamping arm 310 and the circuit board, the connection strength between the magnetic connector and the circuit board can be improved to avoid the situation where the terminals are bent due to excessive force when the magnetic connectors are plugged into each other.

[0038] Reference Figure 2 and Figure 3 In some embodiments of the present invention, one end of the terminal 20 away from the boss 110 is bent toward the side where the elastic clamping arm 310 is provided, so as to facilitate welding of the terminal 20 to the connection point on the circuit board.

[0039] Magnetic connectors generally include male and female connectors, which work together to achieve electrical connection.

[0040] Reference Figure 1and Figure 4 In some embodiments of the present invention, the end surface of the boss 110 is located inside the opening 410, and one end of the terminal 20 protrudes from the boss 110 and is located inside the opening 410. In this female magnetic connector, since the end of the terminal 20 is inside the opening 410, the terminal 20 can be better protected to prevent the terminal 20 from bending or even breaking.

[0041] Reference Figure 5 and Figure 6 In some embodiments of the present invention, the end face of the boss 110 of the male magnetic connector protrudes from the magnet 40, the boss 110 covers one end of the terminal 20, and only the end face of the terminal 20 is exposed outside the boss 110. In this male magnetic connector, since the end of the terminal 20 extending outside the magnet 40 is wrapped inside the boss 110, and only the end face is exposed to the outside, the boss 110 can better protect the terminal 20, avoiding the problem of bending or even breaking of the terminal 20, and at the same time does not affect the conductive connection with the female connector. Specifically, in order to make only the end face of the terminal 20 exposed outside the boss 110, the end face of the terminal 20 is flush with the end face of the boss 110.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
