<p>An independent holeless socket comprises: a shutter rotation device and a rotary conducting sheet mounting device. A cam (34) is mounted below a shutter (9), a rotary bracket (19) is mounted on a socket base (1), the rotary bracket (19) enables, by a rotary bracket shaft(16), the shutter (9) to open or close in a rotation manner, the rotary bracket shaft(16) is connected to the socket base (1), a spring (15) is mounted on the rotary bracket shaft(16), the shutter (9) is mounted on a shutter shaft (24), and the shutter shaft (24) is mounted on a shutter shaft bracket (11). When a plug is pressed against the shutter (9), the shutter (9) rotates downwards to expose holes (41), and after the plug is inserted, the cam (34) behind the shutter (9) pushes a rotary bracket tail to enable the rotary bracket tail to rotate outwards, and enables, according to the lever principle, rotary bracket heads of the electrified conducting sheets to rotate inwards to be fastened on the pins of the plug, thereby avoiding disconnected phenomenon. The appearance of the socket is a sealed cube and holes cannot be seen, so the socket is safer, disconnection is avoided, no spark flashes, the resistance is not increased, and the service life is prolonged.</p> |
