[0002] A power connection plug is a device that connects electrical appliances and other devices to a power source. It contacts the current inside the socket through electrodes, and then conducts the current to the wires, which ultimately transmit the current to the electrical appliances.
[0003] Currently, plugs on the market usually fix electrodes on the outside of the plug. When the plug is collided, the electrodes are easily bent, thereby affecting the normal use of the plug. Most power connection plugs are prone to poor contact and arcing when loose. Sometimes when you need to use the plug at night, you need to turn on the light to find it, which is not very convenient. When using the power connection plug in summer, it is easy for the plug to overheat and the hand to slip due to sweat, which poses certain safety hazards. Therefore, a power connection plug is proposed to address the above problems. Utility Model Content

[0024] There are two insulating springs 2, and the natural length of the insulating spring 2 is one quarter of the width of the power connection plug shell 1. The natural length of the insulating spring 2 ensures that the elastic force generated during the stretching process will not be too large, so that the elastic force generated will not affect the use process of the power connection plug; the first insulating shaft 3 and the guide groove 12 are located on the same straight line, so that the guide groove 12 can well constrain the moving direction of the first insulating shaft 3; there are two first insulating pull rods 4, and the two parts of the first insulating pull rod 4 are symmetrically positioned, so that the force magnitudes of the two parts of the first insulating pull rod 4 are equal, and the force directions of the two parts of the first insulating pull rod 4 are symmetrical; the fluorescent sheet 15 is located at the top of the power connection plug shell 1 close to the electrode 6, ensuring that the bright light emitted by the fluorescent sheet 15 can illuminate the electrode 6 when the power connection plug is used at night.
[0025] Working process: When using the power connection plug, if it is at night, find the power connection plug through the light emitted by the fluorescent sheet 15, hold the power connection plug housing 1 with your hand and put your fingers close to the anti-slip groove 16 to grab the power connection plug, and then pull the insulating handle 14 with your other hand. The insulating handle 14 moves while driving the second insulating pull rod 8 to move. Since the second insulating pull rod 8 is constrained by the guide groove 12, the second insulating pull rod 8 will move along the fixed direction of the guide groove 12, so that the second insulating pull rod 8 drives the first insulating shaft 3 to move, and the first insulating shaft 3 moves while driving The first insulating pull rod 4 is displaced. Due to the rotational connection between the first insulating shaft 3 and the first insulating pull rod 4, the first insulating pull rod 4 will rotate toward the middle when displaced. Because the first insulating pull rod 4 is rotationally connected to the second insulating shaft 5, the first insulating pull rod 4 will drive the second insulating shaft 5 to move toward the middle, and then the second insulating shaft 5 will drive the electrode 6 to move toward the middle. The electrode 6 rotates toward the middle due to the action of the conductive shaft 7. While the electrode 6 moves, the insulating spring 2 is stretched toward the middle. When the electrode 6 is blocked by the power connection plug shell 1, the two parts of the electrode 6 remain horizontal. At this time, the power connection plug can be inserted into the power socket. When the power connection plug is fully inserted into the power socket, heat is generated when power is turned on. At this time, the heat is discharged from the power connection plug through the heat dissipation holes 18 on the outer wall of the power connection plug shell 1. The insulating handle 14 is loosened. Since the insulating spring 2 has been deformed before, an elastic force is generated inside the insulating spring 2. At this time, the two parts of the insulating spring 2 will drive the two parts of the electrode 6 to move to both sides. Since the two parts of the electrode 6 are subjected to forces directed to both sides at this time, the two parts of the electrode 6 expand to both sides. Thereby preventing the power connection plug from falling off, the current will be transmitted to the conductive shaft 7 along the electrode 6, and the conductive shaft 7 will transmit the current to the terminal piece 9, and the current will be transmitted to the wire 11 fixed by the screw 10 and the terminal piece 9 by the terminal piece 9. Due to the effect of the wire sheath 13, the two parts of the wire 11 will be integrated into a flex wire 17, and finally the current will be transmitted to the electrical device along the flex wire 17. When the use of the power connection plug is finished, pull the insulating handle 14, and the electrode 6 will converge to the middle according to the above steps, so that it can be easily removed, and the use of the power connection plug is completed through the above operation.
