TECHNICAL FIELD

[0001] The utility model relates to a power connector, especially a power connection device and a self-locking power plug which are easy to plug and unplug. BACKGROUND

[0002] The power plug is a power connection device commonly used by general electrical appliances. After being plugged into the socket, the power plug is only clamped by the conductive copper sheet in the socket to avoid falling off. Since the clamping force of the copper sheet is limited, if the power cord is accidentally pulled by external force, the power plug is likely to fall off, causing power interruption. In addition, the power plug is used to transmit high-voltage current, and its loosening may cause the danger of electric shock. Therefore, how to make the plug stably inserted into the socket hole and not easily loosened by external force is a problem to be solved in this technical field. SUMMARY

The insulating seat has a mating surface and is defined with an insertion direction towards the mating surface. An orbit is arranged in the insulating seat parallel to the insertion direction, and a first channel, a second channel and a third channel are respectively connected to the mating surface. The conductors are embedded in the insulating seat, and the conductors are respectively exposed in the first channel, the second channel and the third channel. The locking sheet is arranged in the insulating seat and crosses the first channel. The locking sheet has a through hole, a fixed side and a movable side opposite to the fixed side. The fixed side is positioned in the insulating seat, and the movable side is movably arranged between the second channel and the third channel. The sliding block is arranged in the orbit and can move along the orbit between a release position and a locking position. The sliding block hooks the movable side of the locking sheet and can drive the locking sheet to deflect. The sliding block has a handle, and the handle extends out of the insulating seat. The resilient element is arranged in the insulating seat and respectively abuts the insulating seat and the sliding block to pre-load the sliding block with a force opposite to the insertion direction and towards the locking position. When the sliding block is located at the release position, the locking sheet is perpendicular to the longitudinal direction of the first channel. When the sliding block is located at the locking position, the locking sheet is inclinedly arranged relative to the longitudinal direction of the first channel.

[0005] In an embodiment of the utility model, the insulating seat includes a body and a shell. The body is arranged in the shell.

[0012] In one embodiment of the utility model, a longitudinal pin is protruded in the longitudinal slot, and the longitudinal pin is inserted with the elastic element.

[0013] In one embodiment of the utility model, the sliding block is provided with a hook claw, and the hook claw hooks the movable side of the locking piece.
