DETAILED DESCRIPTION

[0024] The specific embodiments of the present application will be further described below with reference to the drawings. It should be noted that the description of these embodiments is intended to help understand the present application, but does not constitute a limitation of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0025] As Figure 1-7 shown:

[0026] A magnetic break type sealing socket combination, comprising a sealing socket and a plug 7, the surface of the socket has a conductive structure A63 extending to the inside, the plug 7 has a conductive structure B72 movably connected with the outside of the conductive structure A63; the socket is provided with a breaking device, the breaking device comprises a rotating shaft 2 and a permanent magnet block A3 (the best preferred example is annular, the annular magnet is in a torque balance state during rotation, which is easier to rotate and control) mounted on the rotating shaft 2, and further comprises a switch mechanism controlled by the rotating shaft 2 and a reset mechanism for resetting the position of the rotating shaft 2, the output end of the switch mechanism is connected with the conductive structure A63; the front side of the plug 7 is provided with a permanent magnet block B71 matched with the permanent magnet block A3, the opposite sides of the permanent magnet block A3 and the permanent magnet block B71 are opposite poles, and the center line of the magnetic pole of the permanent magnet block A3 is in a deflection state.

[0027] Specifically, the switch mechanism comprises at least one set of insulating shaft seat 1 and conductive shaft seat 4 (generally one set of control live line can be used, and multiple sets of lines can be controlled by multiple sets) through which the rotating shaft 2 passes, the inner wall of the shaft hole of the insulating shaft seat 1 is embedded with a first arc-shaped conductive piece 11, the rotating shaft 2 is an insulator, a second arc-shaped conductive piece 21 is embedded on the surface of the rotating shaft 2 between the insulating shaft seat 1 and the conductive shaft seat 4, one end of the conductive shaft seat 4 and the first arc-shaped conductive piece 11 is connected with the conductive structure A63, and the other end is connected with the incoming line end. The advantage of this structure is that it only needs to rotate the rotating shaft 2 to realize switching, and does not need to drive other additional mechanisms, which can reduce resistance, thereby reducing the volume of the permanent magnet block A3 and the permanent magnet block B71. When the socket and the plug 7 approach, the opposite poles attract each other, and the center line of the magnetic pole of the permanent magnet block A3 is in a deflection state, so it has a tendency to deflect horizontally under the action of magnetic force, thereby causing the generation of torque, causing the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the first arc-shaped conductive piece 11 coincides with the second arc-shaped conductive piece 21, and the second arc-shaped conductive piece 21 is always in communication with the conductive shaft seat 4, thereby realizing the connection of the line. When the plug 7 is removed, the magnetic force disappears, and the rotating shaft 2 returns to the original position under the action of the reset mechanism, the first arc-shaped conductive piece 11 is misaligned with the second arc-shaped conductive piece 21, and the circuit is disconnected. This switch mechanism is only a preferred example of the control of the rotating shaft 2, and does not constitute a limitation of the present application.

[0028] Specifically, the reset mechanism adopts a torsion spring 5, and the two sides of the torsion spring 5 are respectively installed between the side of the permanent magnet block A3 and the side of the insulating shaft seat 1. After the rotating shaft 2 rotates, the torsion spring 5 is twisted. After the magnetic force disappears, the torsion spring 5 is reset. Since the rotating shaft 2 and the permanent magnet block A3 are both annular, they are in a torque balance state in the absence of external force, so a very small torque can be used for reset.

[0029] Specifically, it also includes a positioning structure, which is composed of a latch A22 on the conductive shaft seat 4 and a latch B23 on the rotating shaft 2. The advantage of adding this structure is that it can make the torsion spring 5 have a certain initial force, and its rotation direction and reset point are limited by the latch A22 and the latch B23, which can increase the reset accuracy of the rotating shaft 2.

[0030] Specifically, the surface of the socket is recessed inward to form a card slot 61, and slots 62 are provided on both sides of the card slot 61, and the depth of the slot 62 is lower than the card slot 61, and a conductive structure A63 matching the edge shape of the slot 62 is embedded in the slot 62; the conductive structure B72 of the plug 7 matches the shape of the slot 62 and is provided on both sides of the plug 7. The advantage of this structure is not only that it can increase the bonding strength between the socket and the plug 7, but also that the permanent magnet block A3 and the permanent magnet block B71 can be as close as possible, thereby increasing the magnetic effect. As a preferred solution, the card slot 61 and the plug 7 have an asymmetric geometric shape, so that when it is necessary to specify the electrode connection method, inversion can be avoided.

[0031] Specifically, the deflection angle of the center line of the magnetic pole of the permanent magnet block A3 is 45 degrees. If the deflection angle is too low, the overlap angle between the first arc-shaped conductive piece 11 and the second arc-shaped conductive piece 21 will be low after rotation, which is not conducive to conductivity. If the angle is too large, it may cause the torque to be too low. Therefore, choosing a deflection angle of about 45 degrees can take into account the problems of torque and overlap range.

[0032] Specifically, both permanent magnet block A3 and permanent magnet block B71 use neodymium magnets, which have strong magnetism and better control effect.

[0033] The advantage of the present invention is that it utilizes the principle of attraction between opposite magnetic poles. The deflected magnetic poles generate torque to drive the switch mechanism to control the automatic opening and closing of the socket combination. Moreover, the socket is in a sealed state, which can effectively protect the internal circuit of the socket. When the plug 7 is not close, the conductive structure A63 is in a power-off state and will not be conductive when touched by external hands. Due to the use of magnetic pole deflection and twisting, the approach of magnetic materials that generally do not have magnetic poles, such as iron, will not cause electric shock to the conductive structure A63, thereby increasing the safety and durability of the socket.

[0034] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the described embodiments. Various changes, modifications, replacements, and variations of the embodiments can be made by those skilled in the art without departing from the principles and spirit of the present application, and still fall within the scope of the present application.
