[0019] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0020] Magnetic power connection structure Figure 1 ,2 As shown, it can be used as a wiring board, an electrical connection socket (such as a light bulb socket) and other application scenarios. Therefore, the power connection unit 1 can be used independently or in combination. Because of the good overall sealing, it is easier to improve the watertightness, and in the non-contact state, the middle electrode 7 on the power connection unit 1 is not charged, avoiding the occurrence of accidental touch and leakage. In addition, an indicator light can be installed on the power connection panel 6, and the two poles of the indicator light are respectively connected to the two poles of the middle electrode 7. When the middle electrode 7 is energized and working, the light is turned on to prompt. In addition to indicating the working status, when the elastic element 5 fails and the middle electrode 7 and the output electrode 4 cannot be separated after the power unit 2 leaves, the lighting state of the indicator light can be used to remind the user that the middle electrode 7 on the contact panel is energized and faulty, which has a warning function.

[0021] The inner and outer surfaces of the power connection unit 1 of the magnetic power connection structure are provided with intermediate electrodes 7 electrically connected to each other. The power connection panel 6 is made of insulating material or has an insulating coating on the outer surface, for example, it is made of insulating plastic sheets. The power connection unit 1 can be an independent sealed cavity. A movable plate 3 is provided in the power connection unit 1. The power connection panel 6 and the movable plate 3 are supported by an elastic element 5. The elastic element 5 is preferably a supporting spring. The movable plate 3 is provided with an output electrode 4 corresponding to the position of the intermediate electrode 7 on the side facing the power connection panel 6. The power connection end surface of the power-consuming unit 2 is provided with an input electrode 8 corresponding to the position of the intermediate electrode 7. The input electrode 8 supplies power to the power-consuming unit 2. When the power-consuming unit 2 does not contact the power connection unit 1, the elastic element 5 supports the movable plate 3, so that the movable plate 3 is separated from the power connection panel 6 and is in an unpowered state. When the external magnet 9 attracts the movable plate 3, the movable plate 3 will press the elastic element 5 to make the movable plate 3 contact the power connection panel 6. At this time, the output electrode 4 on the movable plate 3 contacts the intermediate electrode 7 on the inner side of the contact panel. It is necessary to make the attraction of the magnet 9 and the movable plate 3 in the initial state greater than the supporting force of the elastic element 5.

[0022] The movable plate 3 is made of iron or magnetic material, and a magnet 9 is provided on the inner side surface of the power-connecting end surface to achieve attraction. Because there are many iron objects, in order to avoid accidental touch due to other iron objects contacting the power-connecting panel 6, such as a key placed on the power-connecting panel 6, the movable plate 3 is preferably an iron thin plate. In addition, the movable plate 3 and the magnet 9 are annular structures of the same or similar shape and size. Because of the same size, during magnetic attraction, the magnet 9 aligns the movable plate 3 and the magnet 9 (power unit 2) as much as possible. The magnetism will have the function of guiding and aligning, and can also make the electrode connection reliable. Then, the power-connecting panel 6 can be made into a planar structure, and there is no need to place the intermediate electrode 7 in the groove, and the groove is used for positioning.

[0023] The intermediate electrode 7, the output electrode 4 and the input electrode 8 are all composed of a positive electrode and a negative electrode, wherein the intermediate electrode 7 penetrates the power connection panel 6, or the intermediate electrode 7 on both sides of the power connection panel 6 is two independent components, which are electrically connected through a wire penetrating the power connection panel 6. The intermediate electrode 7 on the outer surface of the power connection panel 6 is composed of a ring electrode and a center electrode, and the positive electrode and the negative electrode of the input electrode 8 on the power unit 2 are two contact points, and the distance between the two contact points is the same as the radius of the ring electrode, so that the input electrode 8 on the power unit 2 can complete the electrical connection with the intermediate electrode 7 in any direction.

[0024] The output electrode 4 is electrically connected to the power supply through a wire, and the control of whether the external intermediate electrode 7 is charged or not is achieved through the movement of the movable plate 3. To ensure the reliability of the connection, the output electrode 4 is a metal part protruding from the movable plate 3, and the input electrode 8 is a metal part protruding from the power-connected end surface. The preferred method is to adopt a retractable structure, and a hole for embedding the input electrode 8 is provided on the power-connected end surface. The input electrode 8 is supported and fixed in the hole of the power-connected end surface by a spring, and the end protrudes from the hole. The movable plate 3 is provided with a hole for embedding the output electrode 4. The output electrode 4 is supported and fixed in the hole of the movable plate 3 by a spring, and the end protrudes from the hole. In this way, the spring will be used to compress the two electrodes each time they contact to avoid short circuit. Even if it is used on a moving object, such as an automobile, the reliability of the electrical connection can be guaranteed.

[0025] In order to further improve the safety of the device, a safety lock is provided on the power panel 6. The form of the safety lock can be any form, the purpose of which is to lock the movable plate 3 when it is not powered on. It is preferably a physical structure that is simple and reliable. For example, the safety lock is provided with a connecting rod, and a laterally extending locking rod is provided at one end of the connecting rod. The connecting rod is on one side of the movable plate 3, and the length of the connecting rod is slightly shorter than the distance between the movable plate 3 and the power panel 6 when it is not powered on. The other end of the connecting rod extends outside the power panel 6. The connecting rod can be rotated so that the locking rod blocks the movable path of the movable plate 3, which is used to lock the movable plate 3 when it is not powered on. The locking rod can also be rotated to allow the movable plate 3 to move normally.

[0026] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
