[0051] The following will be described in more detail with reference to the accompanying drawings for various embodiments. The description and drawings are provided for illustration only and are not intended to be limiting. Similar symbols are used to indicate similar components. For clarity, the components in the drawings may not be drawn according to the actual scale. In addition, some components and / or symbols may be omitted in some drawings. It is expected that the components and features in one embodiment can be advantageously incorporated into another embodiment without further elaboration.

[0052] Please refer to Figures 1A-1H FIG. 1 is an exemplary inlet 100 of the present invention, which is applied to a charger, wherein: Figure 1A is a three-dimensional diagram of the socket 100, Figure 1B is a three-dimensional exploded view of the socket 100. Figure 1C is a top view of the socket 100, Figure 1D is a bottom view of the socket 100, Figure 1E is a left side view of the socket 100, Figure 1F is a right side view of the socket 100, Figure 1G is a front view of the socket 100, Figure 1H is a rear view of the socket 100. To aid understanding of the components, Figure 1A and Figure 1B The neutral wire 202 , the live wire 204 , and the flying wire 206 of the charger are further shown in dashed lines.

[0053] The socket 100 includes a main body 110, a first plate 120, a circuit board assembly 130, and a second plate 140. The first plate 120 is disposed on the main body 110. The first plate 120 has a first hole 122. The circuit board assembly 130 is disposed on the first plate 120. The circuit board assembly 130 has a second hole 1322. The second plate 140 is disposed on the circuit board assembly 130. The main body 110 has a first pin 112 that passes through the first hole 122 and the second hole 1322 and is covered by the second plate 140.

[0054] More specifically, the body 110 includes a first pin 112, a second pin 114, and a third pin 116. The first pin 112, the second pin 114, and the third pin 116 of the body 110 may be a ground pin, a live pin, and a neutral pin. In some embodiments, the first pin 112 is a ground pin, the second pin 114 is a live pin, and the third pin 116 is a neutral pin. The second pin 114 may be configured to clamp and electrically couple the live wire 204. The third pin 116 may be configured to clamp and electrically couple the neutral wire 202. The first pin 112, the second pin 114, and the third pin 116 are conductive. In some embodiments, each of the first pin 112, the second pin 114, and the third pin 116 is entirely formed of a conductive material.

[0055] The body 110 may further include an outer cover 118. The first pin 112, the second pin 114, and the third pin 116 are disposed on one side of the outer cover 118 (the side in the positive Z direction in the drawing). The outer cover 118 may include a wire connection portion 1182. The wire connection portion 1182 may be formed on the other side of the outer cover 118 (the side in the negative Z direction in the drawing). The outer cover 118 may be formed by connecting to a housing of the charger (e.g. Figure 2A-2B According to some embodiments, the outer cover 118 may have at least one first fastening portion 1184 for connecting the first plate 120 .

[0056] The first plate 120 may have at least one second fastening portion 124 corresponding to the first fastening portion 1184 to fasten the first plate 120 to the body 110. For example, the first fastening portion 1184 may be a pin and the second fastening portion 124 may be a hole, but the present invention is not limited thereto. The first plate 120 may be insulated.

[0057] The circuit board assembly 130 may be a printed circuit board assembly. According to some embodiments, the circuit board assembly 130 may include a circuit board 132, a gas discharge tube 134, and a resistor 136. The circuit board 132 has the second hole 1322. The second hole 1322 is configured to accommodate and electrically couple the first pin 112. For example, the circuit board 132 may have a conductive portion (a dotted shading portion) extending to the edge of the second hole 1322 for electrically coupling the first pin 112. The gas discharge tube 134 and the resistor 136 are disposed on the circuit board 132. In some embodiments, the circuit board 132 further has a third hole 1324. The third hole 1324 is configured to accommodate and electrically couple the flying lead 206. Similarly, the circuit board 132 may have a conductive portion extending to the edge of the third hole 1324 for electrically coupling the flying lead 206. The gas discharge tube 134 and the resistor 136 may be disposed between the second hole 1322 and the third hole 1324.

[0058] The second plate 140 covers the first pin 112 to prevent the first pin 112 from contacting components of a main circuit board assembly (to be described later) and causing a short circuit when the socket is mounted on the charger. The second plate 140 may be insulating.

[0059] When the socket 100 is to be assembled, the first plate 120 is first assembled to the main body 110 and fastened, for example, by the first fastening portion 1184 and the second fastening portion 124. At this time, the second pin 114 and the third pin 116 are covered by the first plate 120, and the first pin 112 passes through the first hole 122 and protrudes outside the first plate 120. Next, the circuit board assembly 130 is assembled in such a way that the first pin 112 further passes through the second hole 1322. Then, a conductive contact (a dot-shaped shading portion) is formed between the first pin 112 and the circuit board assembly 130 by welding (tinning) or the like. After that, the second plate 140 is assembled. The second plate 140 can be fixed to the first plate 120 and / or the main body 110 by a mechanical structure, which is not limited by the present invention.

[0060] Now please refer to Figures 2A-2C , which shows an exemplary charger 10 of the present invention, wherein: Figure 2A is a three-dimensional diagram of the charger 10, Figure 2B is a top view of the charger 10, Figure 2C It is a top view of the charger 10 with part of the outer shell removed.

[0061] The charger 10 includes a charging head 20. The charging head 20 includes a housing 22, a main circuit board assembly 24, and a socket 100. The housing 22 has a socket opening (filled by the socket 100 in the figure). The main circuit board assembly 24 is disposed in the housing 22. The socket 100 is disposed in the socket opening. As described above, Figure 1A and Figure 1B, the socket 100 includes a body 110, a first plate 120, a circuit board assembly 130, and a second plate 140. The body 110 includes a first pin 112, a second pin 114, and a third pin 116. The first plate 120 is disposed on the body 110. The first plate 120 has a first hole 122. The circuit board assembly 130 is disposed on the first plate. The circuit board assembly 130 has a second hole 1322. The second plate 140 is disposed on the circuit board assembly 130. The first pin 112 passes through the first hole 122 and the second hole 1322, and is covered by the second plate 140. Other features of the socket 100 are not repeated here.

[0062] Figure 2C The main circuit board assembly 24 is shown as an example to have a high voltage area R1 and a low voltage area R2 separated from each other. The distance d between the high voltage area R1 and the low voltage area R2 should be at least equal to the safety distance required by the laws and regulations of various countries, for example, 7 mm. The main circuit board assembly 24 can be a printed circuit board assembly. The main circuit board assembly 24 includes a component 26 located in the high voltage area R1 and a component 28 located in the low voltage area R2. However, it should be understood that the present invention is not limited to this. The types and number of components of the main circuit board assembly 24, as well as the division of the high voltage area R1 and the low voltage area R2, will change with the design and actual needs, and will not be repeated here. The socket 100 is arranged in the direction of the second plate 140 toward the inside of the housing 22. Therefore, the second plate 140 of the socket 100 can be close to the high voltage area R1 and electrically coupled to the low voltage area R2 through the flying wire 206. Figure 2C The flying wire 206 and the components in the low voltage region R2 connected thereto are not specifically shown, and a person skilled in the art of the present invention should understand that the connection of the flying wire will vary with the design and actual requirements.

[0063] In some embodiments, the charger 10 may further include a charging cable 30 . The charging cable 30 is configured to be coupled to the charging head 20 .

[0064] In summary, the present invention transfers components (such as but not limited to gas discharge tubes and resistors) originally arranged in one of the low voltage areas to the socket. The socket of the present invention further includes an additional circuit board component that directly contacts the first pin, so that the ground wire used in the traditional charger can be omitted. Thus, a low voltage area can be omitted from the charger, and a safety distance that is usually 7 mm can be omitted. Or, at least the volume of the low voltage area can be reduced. Therefore, using the socket of the present invention, a smaller charger can be provided.

[0065] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. A person having ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
