Detailed Description

The following description of the embodiments of the present utility model refers to the accompanying drawings.

As can be seen in fig. 6, three sets of power connection pads 22 are preset in the plug base 2.

As can be seen from fig. 7, three magnets 21 are arranged in the plug base 2, and: three magnets are arranged in the plug base, and the polarity of each magnet is exchanged when the magnets are arranged with the adjacent magnets, (namely, one magnet is arranged with the N pole upwards and the S pole downwards, and the adjacent magnet is arranged with the N pole downwards and the S pole upwards).

As can be seen from fig. 12, one magnet 41 is located in each magnet carrier 4. And (3) injection: where the magnets 41 disposed in each bracket remain attracted to the magnets 21 disposed in the plug base.

As can be seen in fig. 19, there are three magnet carriers' movable slots 65 in the socket, corresponding to the three magnets in the plug, for mounting three magnet carriers 4.

As can be seen from fig. 20, the hooks 24 on the plug base hook the hook positioning grooves 11 in the plug housing, so that the plug is integrated. The hook 32 of the upper shell of the socket is hooked in the hook positioning groove 63 of the lower shell of the socket, the power connection sheet 31 preset in the upper shell is inserted into the switching groove when the power connection sheet 62 in the lower shell is connected, and the switching groove is connected with the power connection sheet 62 preset in the lower shell, so that the socket is formed into a whole. It can be seen that the plug is held at a distance from the socket in which the magnet 41 in the magnet holder is not attracted by the magnet 21 in the plug base, the magnet holder 4 is pressed against the switch button 5, and the switch button 5 is held against the magnet holder 4 by the underlying spring 51. Because the power switch connection piece 52 below the switch button is at a distance from the power connection piece 61 and the power switching piece 62 in the lower layer of the socket, the socket is in a power-off state as shown in fig. 23.

As can be seen from fig. 21, since the plug is tightly attracted to the socket, the magnet 41 disposed in the magnet holder 4 in the socket is attracted by the magnet 21 in the plug base, the three magnet holders 4 in the socket are synchronously rotated together with the magnet 41, the synchronously rotated magnet holder 4 presses the switch knob 5 to move downward, the downward switch knob 5 forces the downward spring 51 to be synchronously compressed, after the switch knob 5 is moved downward, the power switch connection piece 52 preset below the switch knob is tightly contacted with the power connection piece 61 preset in the socket lower shell and the power connection piece 62, and the power is tightly contacted with the power connection piece 62 in the lower shell from the power connection piece 61 preset in the socket lower shell, and the power connection piece 31 in the socket upper shell is tightly contacted with the power connection piece 62 in the lower shell when being inserted into the transfer groove 68 of the power connection piece in the lower shell, as shown in fig. 24. And (3) injection: to ensure that the power switch tab 52 below the switch button is properly pressed against the corresponding power tab 61 and power switch tab 62 in the lower housing, the slide 54 on the switch button is moved up and down on the slide rail 66 of the lower housing.

As can be seen from fig. 22, when the socket encounters a single magnet 69, the corresponding magnet carrier 4 in the socket rotates with the magnet, the synchronous push switch deflects, and when the bumper of the switch button is inserted into the positioning slot 67 of the lower housing of the switch button, the magnet carrier 4 in the socket stops rotating with the magnet. After waiting for the single magnet 69 to move away, the switch button 5 is reset by the spring 51. When the switch button 5 is shifted, the power switch connecting piece 52 preset below the switch button is not connected with the power connecting piece 61 and the power switching piece 62 in the lower-layer shell, and the power connecting piece in the upper-layer shell of the socket is not electrified, so that the single magnet is close to the socket, and the safety is ensured.

In summary, the working principle of the power supply connection device is as follows: when the plug approaches the socket, the magnet 21 in the plug and the magnet 41 in the socket are attracted to each other, the magnet bracket 4 in the socket is forced to rotate, the rotating magnet bracket 4 presses the switch button 5 to move downwards, the downward moving switch button 5 forces the spring 51 arranged below the switch button to compress synchronously, and the power switch connecting piece 52 preset below the switch button presses the power connecting piece 61 and the power switching piece 62 preset in the lower shell when moving downwards along with the switch button 5, so that the power connecting piece 61 and the power switching piece 62 are connected. After the upper shell and the lower shell are combined, the power connection piece 31 in the upper shell is inserted into the switching groove 68 of the power connection piece in the lower shell to be connected with the power connection piece 62, and the plug is tightly attracted with the socket, so that the power connection piece 22 preset in the plug is connected with the power connection piece 31 preset in the upper shell of the socket. When the plug leaves the socket, the magnet 41 in the magnet bracket in the socket loses attraction, the pressure of the magnet bracket 4 for pressing the switch button 5 is synchronously lost, the switch button 5 losing pressure is supported by the compressed spring 51 again, the power switch connecting sheet 52 is preset below the switch button 5, and the power switch connecting sheet 61 and the power switch connecting sheet 62 are preset in the lower-layer shell along with the switch button 5 to disconnect the power supply in the socket. And (3) injection: because each magnet 21 positioned in the plug is reversed in polarity with the adjacent magnet 21, (i.e., one magnet is positioned with the N pole up and the S pole down, and the adjacent magnet is positioned with the S pole up and the N pole down.) the magnet 41 in each magnet holder 4 of the plug is held in attractive relationship with the magnet 21 in the plug base 2, (i.e., the magnet 21 with the N pole down in the plug is attracted to the magnet 41 with the S pole up in the magnet holder in the plug, the magnet 21 with the S pole down in the plug is attracted to the magnet 41 with the N pole up in the magnet holder in the socket). So that when the plug is in close relationship with the socket, the three power connection tabs 22 in the plug are in positional contact with the three power connection tabs 31 in the upper housing of the socket. (namely, the ground wire, the zero wire and the fire wire in the plug are in positioning contact with the ground wire, the zero wire and the fire wire in the socket.) to prevent the dislocation connection and the short circuit.

The spring 51 under the switch button supports the switch button to prevent downward movement when a large piece of things (e.g., iron) attracted by the magnet is approaching, in addition to supporting the switch button.

The slide 54 on the switch button is intended to move on a slide rail 66 in the lower housing in order to correctly connect the power connection piece 52 preset under the switch button 5 with the power connection piece 61 and the power connection piece 62 in the lower housing.
