The shield 20 matches the shape of the socket 10 and covers the outside of the socket 10 and is connected to the third conductive pin 15 . The anti-electromagnetic interference module 30 is in a long and narrow ring shape and has a through hole 34. The live wire pin 16, the neutral wire pin 17 and the ground wire pin 18 are connected by the socket. The narrow end of 10 extends out to connect to the circuit board 40, wherein the live pin 16 and the neutral pin 17 pass through the through hole 34 to connect to the circuit board 40.

Please refer to Figure 2, which is an exploded perspective view of the anti-electromagnetic interference module. The anti-electromagnetic interference module 30 is an enclosed structure with a through hole 34, such as a long oval or long rectangular narrow annular structure. The structure of the anti-electromagnetic interference module 30 includes a lower cover 31 , a magnetic core 32 and an upper cover 33 . The lower cover 31 has a receiving groove 311 and a first opening 312. The receiving groove 311 is arranged around the first opening 312. The magnetic core 32 is disposed in the receiving groove 311 of the lower cover 31 and has a second opening 321 . The upper cover 33 covers the magnetic core 32 and the lower cover 31 and has a third opening 331 . The first opening 312, the second opening 321, and the third opening 331 are aligned to form a through hole 34 as shown in FIG. 1B. The length of the through hole 34 is set corresponding to the distance between the live pin 16 and the neutral pin 17 so that the live pin 16 and the neutral pin 17 can pass through the through hole 34 . Among them, the lower cover 31 and the upper cover 33 are made of insulating material, and the magnetic core 32 is made of magnetically permeable material.

Please refer to Figure 2 and Figure 3A to Figure 3D together. Figure 3A is a schematic cross-sectional view of the pins installed in the anti-electromagnetic interference module. Figure 3B and Figure 3D are schematic diagrams of the creepage distance. Figure 3C is the distance between the socket pins. Schematic diagram. As shown in FIG. 2 , the upper cover 33 of the anti-electromagnetic interference module 30 has a protruding portion 332 on the surface covering the magnetic core 32 and the lower cover 31 . The protruding portion 332 is provided at a position corresponding to the second opening 321 of the magnetic core 32 . in the second opening 321. As shown in FIG. 3A , the protruding portion 332 of the upper cover 33 includes a first surface 332A, a second surface 332B, and a third surface 332C. The second surface 332B is adjacent to the first surface 332A, and the third surface 332C is adjacent to the second surface 332B. . Preferably, the first surface 332A has an edge closest to the live pin 16 and the neutral pin 17 , and the third surface 332C contacts the magnetic core 32 . In this creation, the so-called creepage distance is defined as the shortest distance between two conductive parts measured by crawling along the surface of an insulating object. Therefore, in this creation, the creepage distance is defined as the shortest distance between the two conductive parts, the live pin 16 and the neutral pin 17, measured by crawling along the surface of the upper cover 33 of the anti-electromagnetic interference module 30.

Furthermore, as shown in FIG. 3B , taking the live pin 16 as a starting point, the distance crawled along the first surface 332A is the first distance d1 , and the distance crawled along the second surface 332B is the second distance d1 . The distance crawled along the third surface 332C from d2 is the third distance d3. After passing through the first distance d1, the second distance d2 and the third distance d3, it has reached the magnetic core 32. Then, as shown in FIG. 3C, since the magnetic core 32 of the anti-electromagnetic interference module 30 is made of magnetically permeable material, Therefore, the fourth distance d4 it crawls is not included in the calculation of the creepage distance. Therefore, as shown in Figure 3D, after passing the first distance d1, the second distance d2 and the third distance d3 to reach the magnetic core 32 , similarly, starting from the magnetic core 32 and passing through the third distance d3, the second distance d2 and the first distance d1, the neutral pin 17 can be reached. Therefore, the total creepage distance is the first distance d1, the first distance d1 and the first distance d1. The sum of the second distance d2, the third distance d3, the third distance d3, the second distance d2 and the first distance d1 is twice the first distance d1, the second distance d2 and the third distance d3.

In addition, the back 12 of the plug-in power socket 1 with the anti-electromagnetic interference module is provided with a first capacitor 19A and a second capacitor 19B. The first end of the first capacitor 19A is connected to the live wire pin 16, and the second end of the first capacitor 19A is connected to the ground wire. Pin 18, the first end of the second capacitor 19B is connected to the ground pin 18, and the second end of the second capacitor 19B is connected to the neutral pin 17. Therefore, through the first capacitor 19A and the second capacitor 19B connected in series, and through the live wire pin 16 and The neutral pin 17 passes through the through hole to connect to the circuit board 40, which can reduce the impact of electromagnetic interference.

Please refer to Figure 1D. Since the anti-electromagnetic interference module 30 is in the shape of a long and narrow ring, the live pin 16 and the neutral pin 17 on the socket 10 are connected to the circuit board 40 after passing through the anti-electromagnetic interference module 30. A first capacitor 19A and a second capacitor 19B are connected between the pin 16, the neutral pin 17 and the ground pin 18. When shielded by the first capacitor 19A and the second capacitor 19B, the lower end of the back 12 of the socket 10 is redundant. The anti-electromagnetic interference module 30 passing through the live pin 16 and the neutral pin 17 can make full use of the redundant space for installation. In this way, the circuit will not be occupied by the installation of the anti-electromagnetic interference module 30 The extra space above the board 40 will not cause squeezing of other wires, and the problem of wire covering damage caused by squeezing can also be completely avoided. In this embodiment, the socket 10 is a C14 type power socket.

Figure 4B is a second perspective view. Figure 4C is a third perspective view. 4D is a schematic cross-sectional view of the pins installed in the anti-electromagnetic interference module. In this embodiment, the main difference from the first embodiment is that the socket 50 of the plug-in power socket 5 with an anti-electromagnetic interference module is a larger C20-type power socket, and the conductive pins 53 and The shapes and connection methods of pins 54, 55 and pins 56, 57, 58 are therefore different from those in the first embodiment. As shown in FIGS. 4B and 4C , the live pins 56 and the neutral pins 57 on the back 52 of the socket 50 are bent and bent through the through holes 34 of the anti-electromagnetic interference module 30 . The socket 50 is relatively large. Therefore, as shown in FIG. 4C , the socket 50 is arranged outside the circuit board 40 and passes through the through holes 34 of the anti-electromagnetic interference module 30 through the bent live pins 56 and neutral pins 57 . Connect circuit board 40. Furthermore, one end of the ground pin is electrically connected to the circuit board 40 through a plug through a hole structure. As shown in Figure 4D, by arranging the live wire pin 56 and the neutral wire pin 57 in the through hole 34 of the anti-electromagnetic interference module 30, and connecting the live wire pin 56, the neutral wire pin 57 and the ground wire pin 58 in series in Figure 4C The first capacitor 19A and the second capacitor 19B can reduce the influence of electromagnetic interference. The other similar principles and structures are as mentioned above and will not be described again here.

To sum up, this invention installs a long and narrow ring-shaped anti-electromagnetic interference module at the lower end of the back of the socket, making full use of the space around the plug-in socket. In addition to the anti-electromagnetic interference function, it will not be affected by the installation of anti-electromagnetic interference components. The internal use of the power supply also effectively solves the problem of squeezing the wire due to the installation of the coil, resulting in damage to the wire coating.
