Detailed Implementation

[0042] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0043] This utility model provides a novel magnetic connector. A first magnetic element 130 and a second magnetic element 230, which are mutually attracted, are respectively provided on the first end 100 and the second end 200, which are to be inserted into each other. Simultaneously, elastic hooks 123 and locking protrusions 223 are respectively provided on the terminal assembly 120 and the insertion piece 220, which are to be inserted into each other. After the first end 100 and the second end 200 are inserted into each other, the elastic hooks 123 lock onto the locking protrusions 223 to ensure the stability of the first end 100 and the second end 200. During the insertion process, the mutual attraction of the first magnetic element 130 and the second magnetic element 230 acts as a guide, facilitating the insertion of the first end 100 and the second end 200. After insertion, the attraction of the first magnetic element 130 and the second magnetic element 230 further improves the stability and reliability of the first end 100 and the second end 200.

[0044] Specifically, such as Figure 1-9 As shown, this embodiment of the present invention provides a novel magnetic connector, including a first end 100 and a second end 200 that are mutually inserted. In this embodiment, the first end 100 is the male end of the connector, and the second end 200 is the female end of the connector. In this embodiment, as... Figure 1-6 As shown, the first end 100 includes a first base 110, a terminal assembly 120, and a first magnetic element 130. Specifically, the first base 110 has a first mounting cavity 111 inside; the terminal assembly 120 is fixedly installed in the first mounting cavity 111, and its end is provided with a recessed insertion groove 121. At least one side of the insertion groove 121 is provided with a first insertion pin 122, and elastic hooks 123 are provided on two opposite sidewalls of the insertion groove 121; the first magnetic element 130 is fixedly installed on the outside of the first base 110.

[0045] like Figure 1-3 As shown in Figures 7-9, the second end 200 includes a second base 210, a connector 220, and a second magnetic element 230. Specifically, the second base 210 has a second mounting cavity 211 inside; the connector 220 is fixedly disposed within the second mounting cavity 211, the connector 220 is adapted to the connector groove 121 and has a second connector 222 formed on one side that abuts against the first connector 122, and the connector 220 has a snap-fit ​​protrusion 223 corresponding to the elastic snap hook 123 formed on two opposite sidewalls; the second magnetic element 230 is fixedly mounted on the outside of the second base 210.

[0046] Wherein, after the first end 100 and the second end 200 are inserted into each other, a space is defined between the first magnetic element 130 and the second magnetic element 230.

[0047] During use, the first end 100 is typically fixedly mounted on one component, and the second end 200 is fixedly mounted on another component. After the first end 100 and the second end 200 are plugged into each other, the two components are interconnected, and signal transmission occurs through the plugged-in first end 100 and the second end 200. When the first end 100 and the second end 200 are plugged in, under the magnetic attraction of the first magnetic component 130 and the second magnetic component 230, the first end 100 and the second end 200 can quickly approach and make contact. Figure 1-3 As shown, it is evident that the first magnetic element 130 is disposed at the bottom of the first base 110, and similarly, the second magnetic element 230 is disposed at the bottom of the second base 210. This ensures that the first end 100 and the second end 200 are guided by the attraction of the first magnetic element 130 and the second magnetic element 230, enabling them to quickly and accurately contact each other. When the magnetic elements attract each other, the upper ends of the first base 110 and the second base 210 make pre-rapid contact, allowing for fine-tuning before inserting the connector 220 into the connector slot 121 of the terminal assembly 120. When the connector 220 is inserted into the connector slot 121 of the terminal assembly 120, the first connector pin 122 and the second connector pin 222 abut against each other. The two parts are connected to each other, and the elastic hook 123 and the locking protrusion 223 engage with each other to ensure the firmness of the first end 100 and the second end 200. After the insertion is completed, a gap space is defined between the first magnetic element 130 and the second magnetic element 230. The first magnetic element 130 and the second magnetic element 230 are separated by this gap space to prevent the first magnetic element 130 and the second magnetic element 230 from attracting each other and becoming tightly attached, which would make it inconvenient to separate them. At the same time, it can make the first magnetic element 130 and the second magnetic element 230 have a certain magnetic attraction, so that the first end 100 and the second end 200 can attract each other and maintain the insertion state, further improving the stability of the insertion.

[0048] In this embodiment, as Figure 5-6 As shown, the terminal assembly 120 includes a first core 124, a first end 100 sub-plate, and an elastic member 126. A insertion groove 121 is formed from one end of the first core 124. A first insertion pin 122 is fixedly disposed on the first end 100 sub-plate, and the first end 100 sub-plate is fixedly mounted on the first core 124. The elastic member 126 is fixedly mounted inside the first core 124 and includes a plate 1261. Elastic arms 1262 are disposed on both sides of the plate 1261, with the lower end of the elastic arm 1262 integrally formed with the plate 1261, and its upper end extending upwards at intervals from the plate 1261. The upper end of the elastic arm 1262 is bent towards the plate 1261 to define an elastic hook 123. A window 1241 is provided on the side wall of the first core 124 for the elastic arm 1262 to extend elastically outwards.

[0049] When the insert piece 220 is inserted into the insert slot 121, the elastic arm 1262 undergoes elastic deformation in the direction away from the plate 1261 after being obstructed by the snap-fit ​​protrusion 223, so that the elastic hook 123 can snap into the inner side of the snap-fit ​​protrusion 223, thus achieving mutual snap-fit ​​and ensuring the reliability of the first end 100 and the second end 200 that are mutually snap-fitted.

[0050] In this embodiment, the lower part of the elastic arm 1262 is formed with a protrusion 1263 protruding outward, and the protrusion 1263 abuts against the inner wall of the first mounting cavity 111. During the elastic deformation of the elastic arm 1262, the protrusion 1263 serves as a fulcrum, thereby increasing the elastic force of the elastic deformation and enabling the elastic hook 123 to have a stronger locking force when it engages with the locking protrusion 223.

[0051] Meanwhile, in order to more smoothly engage the elastic hook 123 with the inner side of the engaging protrusion 223, the outer edge of the elastic arm 1262 is inclined inward from the protrusion 1263 to the elastic hook 123, so that a deformation space is defined between the portion of the elastic arm 1262 from the protrusion 1263 to the elastic hook 123 and the inner wall of the first mounting cavity 111. At the same time, the width of the portion of the elastic arm 1262 from the initial insertion to the elastic hook 123 gradually decreases. This portion is also the main part that achieves elastic deformation. Setting the width of this portion to gradually decrease makes it easier for the elastic arm 1262 to undergo elastic deformation, thereby enabling the elastic hook 123 to engage with the engaging protrusion 223 more smoothly and improving the smoothness of the mutual insertion of the first end 100 and the second end 200.

[0052] like Figure 7-9 As shown, the plug-in piece 220 includes a second core 224, a second end 200 subplate, and a snap-fit ​​piece 226. Specifically, the second core 224 includes a base 2241 and a piece 2242 formed at the end of the base 2241. The base is fixedly installed in the second mounting cavity 211, and the piece 2242 is used to be inserted into the plug-in groove 121. The second end 200 subplate is integrally formed inside the second core 224, and a second plug-in pin 222 is provided on the second end 200 subplate, with the plug-in pin protruding from the side of the piece 2242. The snap-fit ​​piece 226 is formed inside the second core 224, and snap-fit ​​protrusions 223 are formed on both sides of the snap-fit ​​piece 226, with the corresponding side walls of the piece 2242 protruding. The snap-fit ​​protrusion 223 is formed on the snap-fit ​​piece 226, thereby increasing the strength of the snap-fit ​​protrusion 223 and preventing the snap-fit ​​protrusion 223 from deforming inward during repeated insertion.

[0053] In this embodiment, in order to facilitate the production and assembly of the second end 200 sub-board, the second end 200 sub-board includes two plates 2251 stacked on each other, the second plug pin 222 is formed on one of the plates 2251, and the snap-fit ​​piece 226 is clamped between the two plates 2251.

[0054] To enhance the strength of the second end 200 sub-plate, each sheet 2242 is provided with a mating post 2252 and a mating hole 2253. The snap-fit ​​piece 226 is formed with a through hole 2261 for the mating post 2252 to pass through. When two sheets 2242 are stacked and the snap-fit ​​piece 226 is clamped, the mating post 2252 passes through the through hole 2261, and the mating post 2252 of one sheet 2242 passes through the mating hole 2253 of the other sheet 2242. By having the mating post 2252 pass through the through hole 2261 and then into the mating hole 2253, the two sheets 2251 and the snap-fit ​​piece 226 can be integrated into a single unit, thereby increasing the strength of the second end 200 sub-plate.

[0055] To improve the accuracy of the insertion and prevent reverse insertion when the first end 100 and the second end 200 are inserted, an insertion notch 112 is provided on the side wall of the first base 110; the inner wall of the second mounting cavity 211 is formed with an insertion block 212 that matches the insertion notch 112. During the insertion process of the first end 100 and the second end 200, the insertion block 212 is inserted into the insertion notch 112, which serves as a limiting structure for the insertion and prevents reverse insertion.

[0056] Both the first end 100 and the second end 200 need to be connected to other components, typically PCB boards. To facilitate connection with the PCB board, several connecting blocks 113 are formed on the opposite end faces of the first base 110 and the second base 210. At least one connecting block 113 located on the first base 110 / second base 210 has a different cross-sectional area / shape than the other connecting blocks 113. By setting different cross-sectional areas or shapes for the connecting blocks 113, the connecting blocks 113 are designed to prevent mistaken connection, ensuring accurate connection when connected to the PCB board.

Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
