[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4As shown, the present invention discloses a magnetic connection type electrical connector, including a male connector 1, a female connector 2 that mates with the male connector 1, an elastic terminal 11 disposed on the male connector 1, a first magnetic element 12 disposed on both sides of the male connector 1, a fixed terminal 21 disposed on the female connector 2, and a second magnetic element 22 disposed on both sides of the female connector 2. The first magnetic element 12 and the second magnetic element 22 have different magnetic poles and are magnetically attracted to each other, so that the elastic terminal 11 and the fixed terminal 21 are electrically connected.

[0025] Both sides of the male connector 1 are provided with first magnetic elements 12, and both sides of the female connector 2 are provided with second magnetic elements 22. Preferably, the first magnetic elements 12 and the second magnetic elements 22 are magnets. When the male connector 1 and the female connector 2 approach each other, due to the different magnetic poles of the first magnetic elements 12 and the second magnetic elements 22, according to the property of like poles repelling and unlike poles attracting, the first magnetic elements 12 and the second magnetic elements 22 attract each other to fix their positions, so as to facilitate the electrical connection between the elastic terminal 11 and the fixed terminal 21. The connection is time-saving and labor-saving, and the positioning accuracy of the connection between the male connector 1 and the female connector 2 is high. This utility model has a compact structure and reasonable design. It adopts a magnetic connection method to improve positioning accuracy and enhance connection strength. The connection is simple and convenient, improving the performance of the electrical connector.

[0026] The elastic terminal 11 in this embodiment includes a sleeve 111, an inner cavity 112 disposed in the sleeve 111, a spring 113 disposed in the inner cavity 112, a contact head 114 slidably disposed in the sleeve 111, and a ball bearing 115 disposed between the spring 113 and the contact head 114. One end of the spring 113 is connected to the inner cavity 112, and the other end of the spring 113 is connected to the ball bearing 115. Specifically, the structure of spring 113 plus ball bearing 115 is adopted. One end of the spring 113 is connected to the inner cavity 112, and the other end of the spring 113 is connected to the ball bearing 115. When the contact head 114 slides up and down relative to the sleeve 111, the arcuate outer wall of the ball bearing 115 abuts against the outer wall of the contact head 114, which can prevent poor contact caused by the cross-section of the spring 113 getting stuck. The large contact area is conducive to the conduction of large currents.

[0027] In this embodiment, the contact head 114 has an inclined surface 116 near the end of the ball 115. The ball 115 rolls against the inclined surface 116. The contact head 114 is provided with a limiting ring 117, which extends outward from the outer wall of the contact head 114 to prevent it from contacting the inner wall of the sleeve 111. Specifically, the contact head 114 contacts the ball 115 through the inclined surface 116, causing the ball 115 to be placed at an angle on the inclined surface 116. The limiting ring 117 prevents the contact head 114 from contacting the inner wall of the sleeve 111, thus limiting the position of the contact head 114 on the sleeve 111 and preventing the contact head 114 from accidentally detaching from the sleeve 111 due to excessive movement, thereby improving safety.

[0028] The fixed terminal 21 in this embodiment includes a trigger head 211 and a PCB solder pad 212 disposed on the trigger head 211. The contact head 114 abuts against the trigger head 211. Specifically, the trigger head 211 is connected to the PCB solder pad 212, and the PCB solder pad 212 is electrically connected to the PCB board. When the contact head 114 abuts against the trigger head 211, the contact head 114 and the trigger head 211 abut against each other and are electrically connected, resulting in high connection efficiency.

[0029] In this embodiment, the female connector 2 is provided with a silicone ring 23, which is arranged around the circumference of the fixed terminal 21. Specifically, when the male connector 1 and the female connector 2 are connected and assembled, the silicone ring 23 is arranged around the circumference of the fixed terminal 21. The silicone ring 23 plays a waterproof and sealing role, effectively preventing external dust and moisture from entering the interior of the male connector 1 and the female connector 2, and ensuring the normal operation and stability between the contact head 114 and the trigger head 211.

[0030] In this embodiment, the male seat 1 has a first receiving groove 13 on both sides, and the first magnetic element 12 is received in the first receiving groove 13. The female seat 2 has a second receiving groove 24 on both sides, and the second magnetic element 22 is received in the second receiving groove 24. Specifically, the first magnetic element 12 is received in the first receiving groove 13, and the second magnetic element 22 is received in the second receiving groove 24, resulting in a compact structure and good connection stability.

[0031] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
