DETAILED DESCRIPTION
[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0022] In this embodiment, refer to Figure 1 - Figure 8, a new type of safety plug specifically implemented therein includes a shell 1, a neutral wire pin 9, a live wire pin and a ground wire pin 10. The upper ends of the neutral wire pin 9 and the ground wire pin 10 are both provided with an integrally formed wiring portion 12, and the live wire pin includes a plug 11 and a connector 2. Furthermore, the connector 2 is fixed below the fuse 13, and wiring holes 15 are provided in the wiring portion 12 and on the left side of the connector 2. Screws for fixing the wires are installed on the upper ends of the wiring holes 15, so that the neutral wire, ground wire and live wire on the electronic device are respectively connected to the corresponding connection holes 15. The design of the connection holes 15 facilitates the fixing of the wires to avoid poor contact or falling off of the wires causing circuit failures.
[0023] Furthermore, one end of the neutral wire pin 9 , the live wire pin and the ground wire pin 10 are all fixed inside the housing 1 , and the other ends extend outside the housing 1 to be connected to an external socket.
[0024] Furthermore, a first U-shaped part 4 is integrally formed at one end of the plug 11, and the first U-shaped part 4 is connected to the second U-shaped part 5 above the connector 2 through a fuse 13. The first U-shaped part 4 and the second U-shaped part 5 are connected to fix the two ends of the fuse 13 respectively, so that the current enters from the plug 11 and first passes through the fuse 13 and then is conducted to the electronic device. The setting of the fuse 13 provides safety protection for the entire circuit system. When the current exceeds the rated value, the fuse 13 will melt, thereby cutting off the circuit and preventing the occurrence of electronic fires.
[0025] Furthermore, a conductive member 14 is provided between the second U-shaped member 5 and the connecting member 2, and a spring piece 8 that cooperates with the conductive member 14 is provided at the lower end of the second U-shaped member 5 and the upper end of the connecting member 2. The end of the spring piece 8 is provided with a contact portion 20 bent inward, and the contact portion 20 abuts against the conductive member 14, and the conductive member 14 and the spring piece 8 are preferably made of copper or a material with excellent conductivity.
[0026] Furthermore, a button 6 is provided, and a column 16 is provided inside the button 6 and is slidably connected to the shell 1, and a spring 17 is provided on the outside of the column 16. One end of the spring 17 abuts against the outside of the shell 1 and the other end abuts against the button 6, providing a reaction force for the button 6, so that the button 6 is reset to its initial position to prepare for the next press. The setting of the column 16 allows the button 6 to remain stable, avoiding uneven force and tilting, which may cause the button 6 to be unable to be pressed.
[0027] The conductive member 14 is fixed to one end of the button 6. When the user pushes the button 6, it moves the conductive member 14 inward, breaking the contact between the spring 8 and the conductive member 14. This allows the spring 8 to contact the button 6, thereby severing the circuit and reducing the risk of electric shock caused by circuit failure. When the button 6 is released, the reaction force of the spring 17 returns the button 6 to its original position, allowing the spring 8 to contact the conductive member 14 again, restoring the circuit and ensuring normal operation of the plug. The button 6 is preferably made of plastic or a material with good insulating properties.
[0028] Furthermore, when plugging or unplugging a plug, users usually pinch the two sides of the plug with their fingers. Therefore, the button 6 is designed on the side of the housing 1. The user can easily press the button 6 while holding the plug normally, thereby disconnecting the circuit. Only after releasing the hand will the circuit be closed and power will be restored, which significantly improves the safety of electricity use.
[0029] The housing 1 is provided with a step portion 19 around the position of the button 6, and a silicone membrane 7 covering the button 6 is provided on the step portion 19. The silicone membrane 7 is glued to the step portion 19 on all sides by glue, so as to prevent liquid from entering the inside of the plug and damaging the circuit, causing the risk of leakage. The design of the silicone membrane 7 improves the user's feel when pressing the button 6.
[0030] A lamp bead 3 is provided at the upper end of the shell 1. A current-limiting resistor is connected to the positive pole of the lamp bead 3, the current-limiting resistor is connected to the live wire, and then the negative pole of the lamp bead is connected to the neutral wire. The current-limiting resistor prevents the lamp bead 3 from being damaged by excessive current, so that the lamp bead 3 lights up when the plug is powered on, so that the user can understand whether the plug is currently powered on by observing the status of the lamp bead 3. The lamp bead 3 can also serve as a warning, reminding people to pay attention to the live plug to avoid accidental electric shock.
[0031] Furthermore, a guide hole 18 for accommodating a wire is provided at the bottom of the housing 1 , so that the wire on the electronic device can pass through the guide hole 18 and be fixed inside the plug.
[0032] The utility model provides a luminous lamp bead 3 on the upper cover, so that the user can know whether the plug is currently in a power-on state by observing the lamp bead 3, and is provided with a retractable button 6, so that the user pushes the button 6 when taking the plug, and the button 6 pushes the conductive member 14, so that the conductive member 14 is disconnected from the plug 11 and the connecting member 2, and the circuit is thus in a disconnected state, avoiding the risk of electric shock caused by circuit failure when the user touches the plug, and improving the safety of electricity use.
