[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] The embodiment of the present application provides a magnetic attraction connector to solve the problem in the prior art that the magnet of the connector is exposed from the upper surface of the plastic body and is easily oxidized. It should be noted that in the present application, the direction of the plastic body 10 relative to the FPC board 50 is up, above, upper side, upper end, top, top or top, and the opposite direction is down, below, lower side, lower end, bottom, bottom end or bottom.

[0022] like Figures 1 to 4 As shown, an embodiment of the present application is a magnetic connector, comprising: a plastic body 10, a magnet 20, an FPC board 50, a spring ring 40, and a probe group 30; the probe group 30 passes through the inside of the plastic body 10 and is exposed from the upper and lower end surfaces of the plastic body 10, the spring ring 40 is sleeved on the outside of the plastic body 10, the FPC board 50 is arranged on the lower end surface of the plastic body 10, and the lower end of the probe group 30 is exposed after passing through the FPC board 50; the magnet 20 is installed in the plastic body 10, and the upper end surface of the plastic body 10 covers the magnet 20 to ensure that it is not exposed.

[0023] Since the magnet 20 installed inside the plastic body 10 is not exposed from the upper end surface of the plastic body, the plastic body 10 can wrap the magnet 20, so the entire plastic body 10 can protect the magnet 20 and prevent it from oxidation.

[0024] In this embodiment, the magnet 20 is protected by covering the upper end surface of the plastic body 10 with the magnet 20; in this embodiment, the number of magnets 20 and mounting grooves 101 is consistent, and multiple can be provided. In this embodiment, two are taken as an example: specifically, two mounting grooves 101 are provided from the lower end surface to the inside of the plastic body 10, and two magnets 20 corresponding thereto are provided, and the two magnets 20 have the same size. The magnets of the same size are provided here to prevent the risk of wrong installation during installation. Each magnet 20 is correspondingly installed in the mounting groove 101, and the inner wall of each mounting groove 101 is provided with a plurality of long strip ridges 1010. The ridges 1010 are used to increase the friction force when installing the magnet 20. When assembling the magnet 20, the magnet 20 is assembled into the interference with the ridges 1010 to ensure that the magnet 20 is not in a loose state in the mounting groove 101. A clamping protrusion 1011 is also provided on the two opposite side walls in the mounting groove 101, and the clamping protrusion 1011 and the ridges 1010 are arranged at intervals.

[0025] Next refer to Figure 3 In the present embodiment, the magnet 20 can be designed into various shapes. As a preferred solution, the magnet 20 can be designed into a cubic structure. Specifically, it includes a clamping portion 202 and a mounting portion 201. The clamping portion 202 is located below the mounting portion 201. The mounting portion 201 and the clamping portion 202 are transitionally connected by a clamping groove 2012. When the magnet 20 is installed into the plastic body 10, since the width of the clamping portion 202 is smaller than the width of the mounting portion 201, when the magnet 20 is installed into the mounting groove 101, the clamping groove 2012 can just abut against the clamping protrusion 1011 on the inner wall of the mounting groove 101, thereby preventing the magnet 20 from moving downward, ensuring that the magnet 20 does not fall off when it is loose, and preventing the risk of the magnet falling off due to leakage.

[0026] Reference Figure 2 The upper end surface of the plastic body 10 is provided with a positioning hole 104, which does not penetrate the plastic body 10, and is used to play a positioning role when assembling the finished product. The FPC board 50 includes a first board surface 501 and a second board surface 502. The first board surface 501 is laid on the lower end surface of the plastic body 10 and can cover the magnet 20; the second board surface 502 extends outward and away from the plastic body 10, and a board-to-board connector 504 connected to other devices is provided on the second board surface 502. A backing glue 503 is also provided on the side close to the second board surface 502. When assembling the magnetic connector and other parts, the surface film on the backing glue 503 can be torn off and glued to the desired position, thereby fixing the FPC board 50.

[0027] The probe group 30 includes a signal needle 301 and at least one spring needle 302. In the present embodiment, three spring needles 302 are provided. A plurality of needle-accommodating channels extending vertically are provided inside the plastic body 10. Specifically, the needle-accommodating channels include a first needle-accommodating hole 102 and a second needle-accommodating hole 103. The signal needle 301 passes through the first needle-accommodating hole 102, and the spring needle 302 passes through the second needle-accommodating hole 103. A plurality of probe holes are provided on the first board surface 501 of the FPC board 50 at positions opposite to the needle-accommodating channels. The probe holes include a first probe hole 5010 and a plurality of second probe holes 5011. The signal needle 301 passes through the first probe hole 5010, and the spring needle 302 passes through the second probe hole 5011 and then extends out from the lower end surface of the first board surface 501.

[0028] The assembly process of the magnetic connector in this embodiment is as follows: first, assemble the signal pin 301 into the plastic body 10, then assemble the three spring pins 302 into the inside of the plastic body, then put the spring ring 40 on the outer side of the plastic body 10, then install the two magnets 20 into the installation groove 101, fix the magnets 20, and finally weld the FPC board to the rear end surface of the plastic body 10.

[0029] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
