The fourth end 132 of the second elastic sheet 13 rests on the second insulation block 151.
In at least one exemplary embodiment, the first insulation block 141 includes a first inclined plane 1411, a second inclined plane 1412, a first resting plane 1413, and a first connecting plane 1414. One end of the first elastic piece 142 is connected to the first connecting plane 1414, the other end of the first elastic piece 142 is connected to the side wall 113. The first connecting plane 1414 is parallel to the first resting plane 1413. The first inclined plane 1411 is connected to the first connecting plane 1414 and the first resting plane 1413.
The first inclined plane 1411 can rest on the first prong 21 or the second prong 22, and the first insulation block 141 can compress the first elastic piece 142 under the driving of the first prong 21 or the second prong 22.
The second inclined plane 1412 is connected to the first connecting plane 1413 and the first resting plane 1413. The second end 122 of the first elastic sheet 12 rests on the second inclined plane 1412. When the first prong 21 or the second prong 22 rests on the first inclined plane 1411 and pushes the first insulation block 141 to compress the first elastic piece 142, the first prong 21 or the second prong 22 slides along the first inclined plane 1411 and rests on the first resting plane 1413.
In at least one exemplary embodiment, the second insulation block 151 includes a third inclined plane 1511, a fourth inclined plane 1512, a second resting plane 1513, and a second connecting plane 1514. One end of the third elastic piece 152 is connected to the second connecting plane 1514, the other end of the third elastic piece 152 is connected to the side wall 113. The second connecting plane 1514 is parallel to the second resting plane 1513. The third inclined plane 1511 is connected to the second connecting plane 1514 and the second resting plane 1513.
The third inclined plane 1511 can rest on the first prong 21 or the second prong 22, and the second insulation block 151 can compress the third elastic piece 152 under the driving of the first prong 21 or the second prong 22. The fourth inclined plane 1512 is connected to the second connecting plane 1513 and the second resting plane 1513. The fourth end 132 of the second elastic sheet 13 rests on the fourth inclined plane 1512. When the first prong 21 or the second prong 22 rests on the third inclined plane 1511 and pushes the second insulation block 151 to compress the third elastic piece 152, the first prong 21 or the second prong 22 slides along the third inclined plane 1511 and rests on the second resting plane 1513.
FIG. 4 illustrates the plug 2 contacting the socket 1. The working process of the socket 1 is described. When the first prong 21 or the second prong 22 rests on the first inclined plane 1411 of the first insulation block 141 through one of the two jacks 111, the first insulation block 141 compresses the first elastic piece 142 along the first chute 144 until the first prong 21 or the second prong 22 rests on the first resting plane 1413. When the first insulation block 141 compresses the first elastic piece 142 along the first chute 144, the first elastic sheet 12 slides along the second chute 145. The first elastic sheet 12 slides along the second inclined plane 1412 and the second elastic piece 143 releases the stored elastic force. Thus, under the driving of the second elastic piece 143, the first elastic sheet 12 moves toward the second prong 22 or the first prong 21 along the second chute 145 to make the first conductive column 123 of the first elastic sheet 12 contact the second prong 22 or the first prong 21.
Similarly, when the second prong 22 or the first prong 21 rests on the third inclined plane 1511 of the second insulation block 151 through one of the two jacks 111, the second insulation block 151 compresses the third elastic piece 152 along the third chute 154 until the second prong 22 or the first prong 21 rests on the second resting plane 1513. When the second insulation block 151 compresses the third elastic piece 152 along the third chute 154, the second elastic sheet 13 slides along the fourth chute 155. The second elastic sheet 13 also slides along the fourth inclined plane 1512 and the fourth elastic piece 153 releases the stored. Thus, under the driving of the fourth elastic piece 153, the second elastic sheet 13 moves toward the first prong 21 or the second prong 22 along the fourth chute 155 to make the second conductive column 133 of the second elastic sheet 13 contact the first prong 21 or the second prong 22. Thus, when the first prong 21 pushes the first insulation block 141 and the second prong 22 pushed the second insulation block 151, the first conductive column 123 of the first elastic sheet 12 contacts the second prong 22 and the second conductive column 133 of the second elastic sheet 13 contacts the first prong 21. Thus, the socket 1 and the plug 2 forms a loop to make the socket 1 supply power to the plug 2.
In at least one exemplary embodiment, when only the first prong 21 or the second prong 22 passes through the one of the two jack 111, the first prong 21 or the second prong 22 contact to insulation block 141, 151 and is not conductively connected to the socket 1, thus, the socket 1 has a function of preventing electrical shock.
The exemplary embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
