The invention will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a magnetic electrical connector 100 according to an embodiment of the present invention. The magnetic electrical connector 100 includes a first connector 10 and a second connector 20 . The front end of the first connector 10 can be connected to a standard three-wire power socket (not shown), and the rear end of the second connector 20 can be connected to a standard three-wire plug 30. The first joint 10 can cooperate with the second joint 20 to form an electrical connection.

Referring to FIG. 2 to FIG. 4 together, the first joint 10 includes a first seat body 11 made of an insulating material such as a resin material. The first seat body 11 includes a first end face 12 and a second end face 13 that face each other. Three pins 121, 123, and 125 are mounted on the first end surface 12. The pin 121 is an L pole (hot line pole) pin, the pin 123 is an N pole (zero line pole) pin, and the pin 125 is an E pole (ground line pole) pin. The pins 121, 123, 125, etc. described above are for insertion into a standard three-wire power outlet.

In other embodiments, the pins 121, 123, 125 may be omitted to electrically connect the first connector 10 directly to a mains power line.

The first joint 10 further includes a flange 130 surrounding the second end surface 13, and the flange 130 defines a notch at a predetermined position to form a positioning groove 1301. The flange 130 and the second end surface 13 together form a receiving space 1303.

The second end surface 13 is formed with two electrode receiving holes 1305, a switch receiving hole 1307, and a magnet receiving hole 1309. The magnet accommodating hole 1309 is located at the center of the second end surface 13, and the two electrode accommodating holes 1305 and the switch accommodating hole 1307 are arranged around the magnet accommodating hole 1309.

The first joint 10 further includes three first electrodes 131, 133, 135 fixed to the second end surface 13, a first magnetic element 137, and a micro switch 139. In the present embodiment, each of the three first electrodes 131, 133, and 135 is an L pole, an N pole, and an E pole electrode.

In other embodiments, the L pole electrode 131 or the N pole electrode 133 may be disposed on the micro switch 139 as long as the L pole electrode 131 or the N pole electrode 133 is connected to the micro switch 139.

Referring to Figures 2 and 3, the second joint 20 includes a second seat 21 which is made of an insulating material such as a resin material. The second seat body 21 includes a third end face 22 and a fourth end face 23 that face each other. Three jacks (not shown) are formed on the third end face 22 for mating with the standard three-wire plug 30.

In other embodiments, the jacks on the third end face 22 described above may be omitted to electrically connect the second connector 20 to an internal circuit of an electrical appliance.

The fourth end surface 23 is a stepped surface. The edge of the fourth end surface 23 is provided with a positioning protrusion 2301 for engaging with the positioning groove 1301 of the first joint. Further, electrode receiving holes 2302, 2303 and magnet accommodating holes 2304 are formed in the fourth end surface 23. The electrode accommodating holes 2302, 2303 are disposed around the magnet accommodating holes 2304.

The second joint 20 further includes three second electrodes 231, 233, 235 and a second magnetic element 237 fixed to the fourth end face 23. In the present embodiment, each of the three second electrodes 231, 233, and 235 is an L-pole, an N-pole, and an E-electrode. The three second electrodes 231, 233, and 235 are respectively cylindrical, and are respectively fixed in the electrode receiving holes 2302 and 2303 and protrude from the electrode receiving holes 2302 and 2303. The second magnetic member 237 is a magnet that is fixed in the magnet accommodating hole 2304.

The second electrodes 231, 233, 235 are electrically connected to the standard three-wire plug 30 through the jacks on the third end face 22, respectively.

When in use, the first connector 10 can be inserted into a power socket, the second connector 20 can be connected to the plug 30, the first connector 10 and the second connector 20 can be substantially aligned, and the second electrode 231, 233 can be , 235 is inserted into the first electrodes 131, 133, 135. The fourth end surface 23 of the second joint 20 enters the accommodating space 1303. The cooperation of the positioning bumps 2301 and the positioning grooves 1301 facilitates the accurate insertion of the second electrodes 231, 233, 235 into the first electrodes 131, 133, 135. The second electrode 235 presses the elastic contact 1391 such that the micro switch 139 is closed, so that a path is formed between the first electrode 131, 133 and the pins 121, 123, so that current can flow from the power socket to the electric appliance. In the present embodiment, the second electrode 235 simultaneously functions to interfere with the abutting element of the micro switch 139. The first magnetic element 137 and the second magnetic element 237 are attracted to each other such that the first joint 10 and the second joint 20 are maintained in a contact state. The first electrode 135 and the second electrode 235 are electrically connected to each other to provide grounding protection for the electric appliance.

When a person accidentally picks up the electric wire or separates the first joint 10 and the second joint 20, since the first joint 10 and the second joint 20 are in magnetic contact with each other, the first joint 10 can be made with a small force. The second joints 20 are separated from each other. When the first joint 10 and the second joint 20 are separated, the micro switch 139 is restored to the open state, so that an open circuit is formed between the first electrodes 131, 133 and the pins 121, 123. At this time, even if the first connector 10 is inserted into the power socket, the first electrodes 131, 133 are not charged, thereby avoiding the risk of electric shock caused by the human or animal accidentally touching the first electrodes 131, 133.

Rather, it is a cylindrical electrode provided in the electrode accommodating hole 5305. Corresponding to the micro switch 539, the second joint 60 is provided with a special interference element 640 for resisting the micro switch 539 outside the second electrode. When the first joint 50 and the second joint 60 are closed, the abutting member 640 is in contact with the micro switch 539, so that the micro switch 539 is closed.

The other structure of the magnetic conversion device 200 is the same as that of the magnetic conversion device 100, and will not be described here.
