Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Please refer to Figures 1 to 5 The utility model proposes a magnetic connector 100, including a magnetic plug 10 and a magnetic socket 11 assembled with the magnetic plug 10, wherein; the magnetic plug 10 includes a first shell 101, a first magnetic member 102, a PCB board 103 and a first PIN needle 104 electrically connected to the PCB board 103 are installed inside the first shell 101, an indicator light 1031 electrically connected to the PCB board 103 is provided on the PCB board 103, and the first shell 101 is provided with a light guide hole 105 corresponding to the indicator light 1031; the magnetic socket 11 includes a second shell 111, a second magnetic member 112 and a second PIN needle 113 are installed inside the second shell 111; when the magnetic plug 10 is connected to the magnetic socket 11, the first magnetic member 102 and the second magnetic member 112 are magnetically attracted to each other, the first PIN needle 104 and the second PIN needle 113 are connected, and the indicator light 1031 is turned on.

[0030] The magnetic plug 10 is connected to an external electronic device through an external wire, especially in the medical field. The external electronic device can be a medical device such as a defibrillator, a ventilator, a monitor, a color Doppler ultrasound system, etc. The magnetic connector 100 in this embodiment is used on a color Doppler ultrasound system. When the above medical device needs to be used quickly, the medical device needs to be connected to the magnetic socket 11 with a power supply in time. The first magnetic part 102 and the second magnetic part 112 set on the magnetic plug 10 and the magnetic socket 11 can realize the rapid fixation of the two. The first PIN pin 104 of the magnetic plug 10 is electrically connected to the electronic device, and the second PIN pin 113 of the magnetic socket 11 is electrically connected to the external power supply. When the first PIN pin 104 and the second PIN pin 113 are connected, the external power supply supplies power to the electronic device.

[0031] The indicator light 1031 can be used to display the power connection status of the magnetic plug 10. If the first PIN pin 104 and the second PIN pin 113 in the magnetic plug 10 are powered on, the indicator light 1031 will light up. If the first PIN pin 104 and the second PIN pin 113 in the magnetic plug 10 are not powered on, the indicator light 1031 will not light up. The operator can perform inspection steps based on the indicator light 1031.

[0032] The indicator light 1031 is provided with a light guide column 1032, which is exposed in the light guide hole 105. The light guide column 1032 is used to transmit light to the outside of the first shell 101, so the light guide column 1032 can be made of a light-transmitting material, such as glass, plastic, etc., and can be transparent or other colors. The color of the displayed light changes with the color of the light guide column 1032. The light guide column 1032 needs to be exposed outside the cover 1012 for easy observation by operators.

[0033] During blind plugging and quick plugging, the operator may not be able to align the first PIN 104 and the second PIN 113. The first housing 101 is provided with a recessed plugging slot 1014, the first PIN 104 is exposed at the bottom of the plugging slot 1014, the second housing 111 is provided with a protruding plugging portion 1111 that plugs with the plugging slot 1014, the second PIN 113 is exposed at the top surface where the plugging portion 1111 is connected to the bottom of the plugging slot 1014, and when the magnetic plug 10 and the magnetic socket 11 are plugged, the plugging portion 1111 is plugged into the plugging slot 1014.

[0034] In this embodiment, a plug-in slot 1014 is provided on the magnetic suction plug 10, the magnetic suction plug 10 includes a plurality of first PIN pins 104, the first PIN pins 104 are exposed at the bottom of the plug-in slot 1014, a plug-in portion 1111 is convexly provided on the magnetic suction socket 11, the magnetic suction socket 11 includes a plurality of second PIN pins 113, the second PIN pins 113 are exposed at the top surface of the plug-in portion 1111, when the plug-in portion 1111 enters the plug-in slot 1014, the first PIN pins 104 and the second PIN pins 113 are connected one by one. The plug-in portion 1111 is confined in the internal space of the plug-in slot 1014, when a collision occurs between the magnetic suction plug 10 and the magnetic suction socket 11, the magnetic suction plug 10 is not easy to come out, and the connection stability of the first PIN pins 104 and the second PIN pins 113 is enhanced.

[0035] Furthermore, when the magnetic plug 10 and the magnetic socket 11 are in contact, the two slide relative to each other. During this process, when the plug-in slot 1014 of the magnetic plug 10 slides onto the plug-in portion 1111 of the magnetic socket 11, the plug-in slot 1014 can enter the plug-in portion 1111, thereby avoiding the situation where the first PIN needle 104 and the second PIN needle 113 between the magnetic plug 10 and the magnetic socket 11 cannot be accurately aligned during the contact process, thereby improving the assembly efficiency of the magnetic plug 10 and the magnetic socket 11 and facilitating the operator to use the corresponding equipment.

[0036] It can be understood that, in one embodiment, the magnetic plug 10 can be provided with a plug-in portion 1111, and the plug-in portion 1111 has a first PIN needle 104 exposed on the ground facing the magnetic socket 11, and the magnetic socket 11 can be provided with a plug-in slot 1014 corresponding to the plug-in portion 1111, and a second PIN needle 113 is exposed on the bottom of the plug-in slot 1014. The above setting method can also achieve the purpose of quick plug-in and stable connection of the magnetic plug 10 and the magnetic socket 11.

[0037] To further enhance the quick connection between the magnetic plug 10 and the magnetic socket 11, please refer to Figure 3 The slot periphery of the plug slot 1014 and the top periphery of the plug part 1111 are both chamfered. The chamfered connection between the plug slot 1014 and the plug part 1111 has a smooth transition slope, and a certain inclination is conducive to reducing the friction of the plug part 1111 entering the plug slot 1014.

[0038] In one embodiment, the two side walls of the plug slot 1014 of the magnetic suction plug 10 can be set to different lengths, and the two side lengths of the plug part 1111 can also be set to different lengths corresponding to the two side walls of the plug slot 1014. In this way, the two side walls of different lengths can achieve a foolproof effect, preventing the plug slot 1014 and the plug part 1111 from plugging in the opposite direction during the plugging process, and the first PIN pin 104 of the wall magnetic suction plug 10 and the second PIN pin 113 of the magnetic suction socket 11 are electrically connected in the opposite way. The first PIN pin 104 and the second PIN pin can have a corresponding connection relationship to achieve different functions, such as the magnetic suction socket 11 is electrically connected to the power supply, electromagnetic wave signal or network signal, etc. When the first PIN pin 104 and the corresponding part of the second PIN pin 113 are connected, the electronic device with the magnetic suction plug 10 can realize the functions of power transmission, electromagnetic wave transmission and network transmission. If the first PIN pin 104 and the second PIN pin 113 cannot be plugged in with the corresponding position relationship, the functions of power transmission, electromagnetic wave and network transmission cannot be realized. Therefore, the above arrangement of different length sides of the magnetic plug 10 and the magnetic socket 11 is conducive to achieving a functional connection between the first PIN needle 104 and the second PIN needle 113 .

[0039] In this embodiment, please refer to Figure 2 and Figure 5 The mounting frame 1011 is provided with a first mounting groove 1015 for placing the first magnetic member 102; the second housing 111 is provided with a second mounting groove 1112 at a position corresponding to the first mounting groove 1015, and a second magnetic member 112 is provided in the second mounting groove 1112. The first magnetic member 102 and the second magnetic member 112 are provided to achieve stable connection and quick plug-in between the magnetic plug 10 and the magnetic socket 11. The first magnetic member 102 may be a permanent magnet, and the second magnetic member 112 may be a permanent magnet or an electromagnet. When the second magnetic member 112 is a permanent magnet, the first magnetic member 102 and the second magnetic member 112 are directly magnetically attracted to each other. When the magnetic socket 11 with the second magnetic member 112 installed is powered on, the second magnetic member 112 may be an electromagnet and the electromagnet is powered on to have magnetism, so that the first magnetic member 102 and the second magnetic member 112 are magnetically connected.

[0040] Furthermore, the number of the first magnetic member 102 and the number of the second magnetic member 112 can be set to be two, and the magnetic poles of the two first magnetic members 102 close to the two second magnetic members 112 can be set to be different, that is, a first magnetic member 102 and a second magnetic member 112 are in a single corresponding attraction relationship, and cannot be attracted to another second magnetic member 112, thereby preventing fooling. Therefore, under this setting, the first PIN needle 104 and the second PIN needle 113 in the magnetic plug 10 and the magnetic socket 11 are connected correspondingly to avoid the situation where the opposite plugging direction affects the functional use of the electronic device.

[0041] Specifically, the first mounting groove 1015 is provided inside the first shell 101, and the second mounting groove 1112 is provided inside the second shell 111. The number of the first mounting grooves 1015 is the same as the number of the first magnetic members 102, and the number of the second mounting grooves 1112 is the same as the number of the second magnetic members 112. In the first shell 101, the opening of the plug-in slot 1014 faces outward, and the inwardly protruding portion of the plug-in slot 1014 encloses two first mounting grooves 1015. The two first magnetic members 102 and the two second magnetic members 112 arranged on both sides of the plug-in slot 1014 are opposite to each other, so that when the magnetic plug 10 and the magnetic socket 11 are plugged in, both sides can be fixed, thereby enhancing the connection stability between the magnetic plug 10 and the magnetic socket 11.

[0042] In this embodiment, the first shell 101 includes a mounting frame 1011 and a cover body 1012. A first mounting groove 1015 and a plug-in groove 1014 are provided in the mounting frame 1011. A through hole 1013 is provided on the first shell 101. The external wire enters the first shell 101 through the through hole 1013 and is electrically connected to a PCB board 103 installed in the first shell 101. A first PIN needle 104 is provided on the PCB board 103. A connecting hole 1016 for passing the first PIN needle 104 is provided at the bottom of the plug-in groove 1014.

[0043] During the manufacturing process of the magnetic plug 10 and the magnetic socket 11, the PCB board 103 on the magnetic plug 10 needs to be welded with electronic components and the first PIN needle 104, and the second PIN needle 113 needs to be welded and led out on the magnetic socket 11. The assembly of the first shell and the second shell requires hot pressing. For the above operations, the first magnetic part 102 and the second magnetic part 112 need to be placed in the corresponding first installation groove 1015 and the second installation groove 1112. The first magnetic part 102 and the second magnetic part 112 will be affected by high heat and demagnetization will occur. Therefore, in this embodiment, the first installation groove 1015 and the first magnetic part 102 are filled with heat insulation material, and the second installation groove 1112 and the second magnetic part 112 are filled with heat insulation material. The heat insulation material can be a material with a certain flexibility such as heat insulation glue and porous material, which fills the gap between the magnetic part and the installation groove. The heat insulation material effectively prevents heat from affecting the magnetic force of the first magnetic part 102 and the second magnetic part 112.

[0044] At the same time, after the magnetic plug 10 and the magnetic socket 11 are plugged in, due to Ohm's law, the current passes through and the electrical energy is converted into heat, and the heat insulation material can also isolate the heat. After the heat insulation material fills the gap between the magnetic part and the installation groove, the heat insulation material stabilizes the position of the first magnetic part 102 and the second magnetic part 112, so that the magnetic plug and the magnetic socket 11 will not be affected in the process of moving, colliding, and shaking.

[0045] In order to seal the heat insulating material disposed in the first installation groove 1015 and the second installation groove 1112, the first installation groove 1015 and the second installation groove 1112 are both provided with a cover plate 13 for sealing the groove opening. The cover plates 13 can be disposed in one-to-one correspondence with the installation grooves, or one cover plate 13 can cover the two first installation grooves 1015 at the same time, and one cover plate 13 can cover the two second installation grooves 1112 at the same time. The cover plate 13 can be a hard plate made of heat insulating material to further enhance the heat insulating effect on the magnetic member.

[0046] In this embodiment, please refer to Figure 6 , the magnetic plug 10 also includes a rubber-coated part 14 coated on the first shell 101, and the rubber-coated part 14 is made of a flexible material. The cover 1012 in the first shell 101 of the magnetic plug 10 is used to connect external wires. The rubber-coated part 14 can be made by a soft rubber process. The rubber-coated part 14 has a certain degree of folding and softness, which is convenient for the introduction and use of external wires, and prevents the external wires from being damaged by excessive bending. The first shell 101 of the magnetic plug 10 can adopt a soft rubber-coated hard rubber process, which can ensure the strength of the connector while taking into account the feel. In addition, because the inside of this rubber-coated process is solid, its strength is greatly improved, which increases the service life of the entire magnetic plug 10.

[0047] In this embodiment, the cross-sectional area of ​​the portion of the mounting frame 1011 close to the second housing 111 is larger, and the open end surface of the cover 1012 abuts against this portion, so that the mounting frame 1011 and the cover 1012 are tightly combined. Figure 4 A snap-in hole 1017 is provided on the peripheral side of the mounting frame 1011, and a snap-in portion 1019 is provided protrudingly at a position corresponding to the snap-in hole 1017 inside the cover 1012. When the mounting frame 1011 and the cover 1012 are assembled, the snap-in portion 1019 snaps into and cooperates with the snap-in hole 1017. The snap-in portion 1019 and the snap-in hole 1017 enhance the fixing strength of the cover 1012 and the mounting frame 1011, and the two are not easily separated during movement or collision.

[0048] Specifically, a connecting portion 1018 is extended and protruded from the peripheral side of the mounting frame 1011, and a snap-in hole 1017 is provided on the connecting portion 1018. The connecting portion 1018 extending from the mounting frame 1011 is elastic, which is conducive to the assembly of the snap-in portion 1019 on the cover body 1012 and the snap-in hole 1017 on the connecting portion 1018. The elastic connecting portion 1018 can also be bent, which is convenient for maintenance when the cover body 1012 and the mounting frame 1011 of the magnetic plug 10 are disassembled. The light guide hole 105 at the same position is provided on the rubber-coated part 14, the snap-in portion 1019 is provided on the top cover, and the avoidance hole is correspondingly provided on the first shell 101. When the rubber-coated part 14 is assembled with the first shell 101, the snap-in portion 1019 passes through the avoidance hole and is snap-fitted and fixed to the snap-in hole 1017.

[0049] In this embodiment, the PCB board 103 arranged in the magnetic plug 10 is used to control the protection mechanism of current and power transmission, and the cover body 1012 is provided with corresponding grooves or protrusions and other fixing parts, so that the installation position of the PCB board 103 on the cover body 1012 is fixed, thereby preventing the PCB board 103 from shifting during use and affecting the position of the first PIN needle 104 welded on the PCB board 103.

[0050] Two positioning posts 1113 are protruded from the outer surface of the second shell along the opposite sides of the second PIN needle. The diameters of the two positioning posts 1113 are different. A control circuit board can be provided on the magnetic socket 11. The control circuit board is plugged into and matched with the positioning posts 1113. The positioning posts 1113 ensure the stability of the second PIN needle during the welding process with the control circuit board. At the same time, the different sizes of the two positioning posts 1113 can not only prevent mistakes, but also play a role in positioning.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
