The present application provides a Power adapter 10. Referring to fig. 1, fig. 1 is a schematic application environment diagram of a power adapter according to an embodiment of the present disclosure. The power adapter 10 is a conversion device that supplies power to the electronic device 30. Generally, the power adapter 10 may convert an alternating voltage to a direct voltage. For example, the power adapter 10 is plugged into the socket 50, receives the ac voltage output by the socket 50, and converts the received ac voltage into a dc voltage, which is used to charge the electronic device 30 using electricity, such as a mobile phone and a computer. It is to be appreciated that in other embodiments, the power adapter 10 converts the received ac voltage to a dc voltage that is directly available to the electronic components in the electronic device 30. It is to be understood that the schematic diagram of the application environment of the power adapter 10 is only helpful for understanding the application of the power adapter 10, and should not be construed as limiting the power adapter 10 provided in the present application.

Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic view illustrating a cover in a power adapter according to an embodiment of the present disclosure in a closed state; fig. 3 is a schematic view of the power adapter shown in fig. 2 with a cover in an open state; fig. 4 is an exploded view of the power adapter shown in fig. 2 in a semi-open state. The power adapter 10 includes an adapter body 100, pins 200, a cover 300, and a connecting shaft 400. The adapter body 100 has a first end face 111, and the adapter body 100 has a first mating portion 130. The pins 200 are connected to the adapter body 100. The cover 300 has a second mating portion 320 a. The connecting shaft 400 is inserted through the first engaging portion 130 and the second engaging portion 320a, so that the cover 300 is rotatably connected to the adapter body 100, the cover 300 has a second end surface 311, when the cover 300 is in a closed state, the pins 200 are covered, when the cover 300 is in an open state, the pins 200 are exposed from the first end surface 111, and the first end surface 111 and the second end surface 311 together form a plugging surface of the power adapter 10.

It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

The adapter body 100 is a part that realizes the voltage conversion function of the power adapter 10. The adapter body 100 generally includes a circuit board for voltage conversion, and the adapter body 100 may further include a housing 110 for accommodating the circuit board, and the like. The specific structure included in the adapter body 100 will be described in detail later in conjunction with the exploded view of the power adapter 10.

The plug pins 200 are made of metal, and the plug pins 200 are inserted into the socket 50 and used for receiving an alternating voltage provided by the socket 50. The number of the pins 200 may be, but not limited to, two, and in the present embodiment, the number of the pins 200 is two. The two pins 200 are opposed and spaced apart. The pins 200 may be, but are not limited to, elongated. The end of the pin 200 facing away from the body of the socket 50 is curved to facilitate insertion of the pin 200 into the socket 50. When the pins 200 are inserted into the sockets 50 to receive the first voltage, the circuit board 150 (see fig. 7) of the power adapter 10 is electrically connected to the pins 200 to receive the first voltage transmitted from the pins 200, and the circuit board 150 is used for converting the first voltage into the second voltage.

When the cover 300 is in the closed state, the pins 200 are covered, including but not limited to the following cases: the pins 200 are covered by the cover 300; alternatively, the pins 200 are covered by the adapter body 100; alternatively, the pins 200 are covered by both the adapter body 100 and the cover 300. The case where the pins 200 are covered by the cover 300 is exemplified by the case where the cover 300 has receiving cavities in which the pins 200 are received when the cover 300 is closed, so as to cover the pins 200. The case where the pins 200 are covered by the adapter body 100 is exemplified by the case where the adapter body 100 has a receiving cavity, and when the cover 300 is closed, the pins 200 are received back in the receiving cavity, and in this case, the pins 200 are covered by the adapter body 100. The plug pins 200 are covered by the adapter body 100 and the cover 300, for example, the adapter body 100 and the cover 300 together form a receiving cavity, and when the cover 300 is closed, the plug pins 200 are received in the receiving cavity formed by the adapter body 100 and the cover 300 together.

In the schematic view of the present embodiment, the plug 200 is fixed to the adaptor body 100 and exposed from the first inserting surface. The number of the cover 300 is two for illustration, that is, the cover 300 includes a first cover 320 and a second cover 330. It is understood that in other embodiments, the number of the cover 300 is one.

The cover 300 rotates compared to the adapter body 100, when the cover 300 is in a closed state, the second end surface 311 faces the first end surface 111, and the second end surface 311 is attached to the first end surface 111 or has a gap with the first end surface 111. As can be appreciated, the gap is relatively small, so that the power adapter 10 is relatively compact.

In this embodiment, when the cover 300 is in the open state, the first end surface 111 and the second end surface 311 together form a plug surface of the power adapter 10, and the first end surface 111 is flush or approximately flush with the second end surface 311.

The plugging surface of the power adapter 10 is a surface that is mated with the socket 50 when the plug 200 of the power adapter 10 is inserted into the socket 50, and the plugging surface satisfies the safety requirements of the power adapter 10. When the plug 200 of the power adapter 10 is inserted into the receptacle 50, only the surface that is mated with the receptacle 50 but does not satisfy the safety regulations of the power adapter 10 cannot be referred to as a plug surface of the power adapter 10. Specifically, for the power adapter 10, when the pins 200 of the power adapter 10 are inserted into the sockets 50, in order to prevent the power of the sockets 50 from leaking out through the pins 200 and causing injury to users, the distance between the edge of the pin 200 and the edge of the plugging surface needs to be greater than or equal to a preset distance (also referred to as a safety distance). In the present embodiment, when the cover 300 is in the open state, the distance between the edge of the pin 200 adjacent to the edge 300 of the cover 300 and the edge of the cover 300 away from the pin 200 is greater than or equal to a predetermined distance. For example, for the power adapter 10 suitable for china, the predetermined distance is 6.5 mm. For power adapters 10 suitable for use in other countries or regions, such as europe, the predetermined distance may be other values, such as 5.1mm, or 7.9 mm. In the schematic view of the present embodiment (as shown in fig. 3), when the first cover 320 and the second cover 330 are opened relatively, the distance from the leftmost edge of the pin 200 to the surface of the first cover 320 facing away from the adapter body 100 (i.e., the leftmost surface of the first cover 320) is greater than or equal to the preset distance; likewise, the rightmost distance of the pins 200 is greater than or equal to the predetermined distance from the surface of the second cover 330 facing away from the adapter body 100 (i.e., the rightmost surface of the second cover 330).

Specifically, when the cover 300 includes the first cover 320 and the second cover 330, when the first cover 320 and the second cover 330 are both in the open state: the distance between the edge of the pins 200 adjacent to the first cover 320 and the edge of the first cover 320 facing away from the pins 200 is greater than or equal to 6.5mm, and the distance between the edge of the pins 200 adjacent to the second cover 330 and the edge of the second cover 330 facing away from the pins 200 is greater than or equal to 6.5mm, so as to meet the requirements of safety regulations of power adapters 10 applicable to china.

For power adapters 10 suitable for use in other countries or regions (e.g., europe), the distance between the edge of the pins 200 adjacent to the first cover 320 and the edge of the first cover 320 facing away from the pins 200 is greater than or equal to 5.1mm, and the distance between the edge of the pins 200 adjacent to the second cover 330 and the edge of the second cover 330 facing away from the pins 200 is greater than or equal to 5.1 mm. Alternatively, the distance between the edge of the pin 200 adjacent to the first cover 320 and the edge of the first cover 320 facing away from the pin 200 is greater than or equal to 7.9mm, and the distance between the edge of the pin 200 adjacent to the second cover 330 and the edge of the second cover 330 facing away from the pin 200 is greater than or equal to 7.9 mm.

In the related art, the end face of the adapter body 100 of the power adapter 10, on which the pins 200 are provided, constitutes the mating face of the power adapter 10, in other words, the mating face of the power adapter 10 of the related art is formed only by the end face of the adapter body 100, on which the pins 200 are provided, and therefore, in the related art, the thickness of the adapter body 100 is generally thick. For example, in order to meet the requirements of the safety regulations of the power adapter 10, the thickness of the adapter body 100 (i.e., the width of the plugging surface of the power adapter 10) is set to a preset thickness (e.g., 22mm), and the thickness of the adapter body 100 in the present application and the adapter body 100 in the related art are analyzed below. Since the mating surface of the adapter body 100 is formed only by the end surface of the adapter body 100 where the pins 200 are provided in the related art, the thickness of the adapter body 100 of the power adapter 10 in the related art is thick. In the power adapter 10 of the present application, the second end surface 311 of the cover 300 and the first end surface 111 of the adapter body 100, on which the pins 200 are disposed, together form an insertion surface of the power adapter 10, that is, the sum of the thickness of the adapter body 100 and the thickness of the cover 300 is equal to the predetermined thickness. In other words, the first end surface 111 of the adapter body 100 provided with the pins 200 in the power adapter 10 of the present application is only used as a partial plugging surface of the power adapter 10, that is, the size (i.e., the thickness of the adapter body 100) of the first end surface 111 of the adapter body 100 provided with the pins 200 in the power adapter 10 of the present application cannot satisfy the requirement of safety regulations, but needs to satisfy the requirement of safety regulations with the aid of the cover 300. As can be seen, the thickness of the adapter body 100 in the power adapter 10 of the present application is necessarily smaller than the thickness of the adapter body 100 in the related art. As can be seen, the thickness of the adapter body 100 in the power adapter 10 of the present application is thinner than the thickness of the adapter body 100 in the power adapter 10 of the related art. The thickness of the adapter body 100 refers to the maximum dimension of the adapter body 100 in the thickness direction.

Compared with the related art, in the power adapter 10 provided by the present application, when the cover 300 is in the closed state, the pins 200 can be protected from being damaged and other objects can be prevented from being damaged by the pins 200. When the power adapter 10 needs to be used, the cover 300 is opened to expose the pins 200. Further, the second end surface 311 of the cover 300 and the first end surface 111 of the adapter body 100 together form a plugging surface of the power adapter 10, in other words, the first end surface 111 of the adapter body 100 only constitutes a part of the plugging surface of the power adapter 10, and the thickness of the adapter body 100 can be made thinner, thereby facilitating the miniaturization of the power adapter 10.

In addition, in the power adapter 10 provided in the embodiment of the present application, the adapter body 100 has the first matching portion 130, the cover 300 has the second matching portion 320a, and the connecting shaft 400 is inserted through the first matching portion 130 and the second matching portion 320a, so that the cover 300 can be rotatably connected to the adapter body 100. Therefore, the structure of the power adapter 10 of the present application, in which the cover 300 is rotatably connected to the adapter body 100, is relatively simple and easy to assemble.

In the present embodiment, the cover 300 includes a first cover 320 and a second cover 330. The first cover 320 is rotatably connected to one side of the adapter body 100, and the second cover 330 is rotatably connected to the other side of the adapter body 100. At least one of the first cover 320 and the second cover 330 has the second matching portion 320a, when the first cover 320 and the second cover 330 are both in a closed state, the first cover 320 and the second cover 330 are both located on the same side of the adapter body 100, and the pins 200 are covered; when the first cover 320 and the second cover 330 are both in the open state, the pins 200 are exposed at the first end surface 111. When the first cover 320 and the second cover 330 are both in the open state, the pins 200 are exposed at the first end surface 111, so that the pins 200 can be inserted into the sockets 50.

The first cover 320 is connected to the adapter body 100 and can rotate relative to the adapter body 100, and the first cover 320 has a first sub-end surface 3111. The second cover 330 is connected to the adaptor body 100 and can rotate relative to the adaptor body 100, the second cover 330 has a second sub-end surface 3112, wherein the second end surface 311 includes the first sub-end surface 3111 and the second sub-end surface 3112. When the first cover 320 and the second cover 330 are in a closed state, the first sub-end face 3111 and the second sub-end face 3112 are away from the adaptor body 100; when the first cover 320 and the second cover 330 are both in an open state, the first sub-end surface 3111, the second sub-end surface 3112 and the first end surface 111 together form a plugging surface of the power adapter 10.

The second sub-connecting shaft 420 is inserted into the through hole of the fourth sub-matching portion 334 and the blind hole of the third sub-matching portion 132, and the second anti-return element 520 is fixed to one side of the fourth sub-matching portion 334 deviating from the third sub-matching portion 132, so as to prevent the second sub-connecting shaft 420 from slipping from one side of the fourth sub-matching portion 334 deviating from the third sub-matching portion 132.

In combination with the power adapter 10 provided in any one of the above embodiments, the power adapter 10 further includes a flexible insulating member 60, the flexible insulating member 60 is connected to the cover 300 and the adapter body 100, and the flexible insulating member 60 is disposed corresponding to a gap between the cover 300 and the adapter body 100 that is kicked. Specifically, in the present embodiment, the cover 300 includes a first cover 320 and a second cover 330. The first cover 320 is rotatably connected to one side of the adapter body 100, and the second cover 320 is rotatably connected to the other side of the adapter body 100. The flexible insulating member 60 includes at least one of a first flexible insulating member 610 and a second flexible insulating member 620.

When the power adapter 10 includes the first flexible insulating member 610 and the second flexible insulating member 620, the first flexible insulating member 610 and the second flexible insulating member 620 may be an integral structure or a separate structure. In the schematic view of the present embodiment, the flexible insulating member 60 in which the first flexible insulating member 610 and the second flexible insulating member 620 are integrated is exemplified. When the first flexible insulating member 610 and the second flexible insulating member 620 are the flexible insulating member 60 of the integrated structure, the first flexible insulating member 610 and the second flexible insulating member 620 also cover at least a portion of the first end surface 111. The first flexible insulating member 610 and the second flexible insulating member 620 also cover at least a portion of the first end surface 111, including the first flexible insulating member 610 and the second flexible insulating member 620 covering a portion or the whole of the first end surface 111. It is understood that in other embodiments, the first flexible insulating member 610 and the second flexible insulating member 620 are separate structures. When the first flexible insulating member 610 and the second flexible insulating member 620 are separate structures, the first flexible insulating member 610 and the second flexible insulating member 620 may or may not be connected (i.e., spaced apart). When the first flexible insulating member 610 and the second flexible insulating member 620 are separate bodies, the first flexible insulating member 610 and the second flexible insulating member 620 cover at least a portion (i.e., a portion or all) of the first end surface 111.

The first flexible insulating member 610 may be made of any flexible and insulating material, such as plastic, silicone, etc. Accordingly, the second flexible edge member may be made of any flexible and insulating material, such as plastic, silicone, etc.

In one embodiment, the first flexible insulating member 610 connects the first cover 320 and the adapter body 100 and is disposed corresponding to a gap between the first cover 320 and the adapter body 100. Specifically, the first flexible insulating member 610 covers the gap between the first cover 320 and the adapter body 100 to cover the gap between the first cover 320 and the adapter body 100, so that the power of the pin 200 cannot pass through the gap at the connection position of the first flexible insulating member 610 and the adapter body 100 to cause the user to hold the pin, thereby improving the safety of the power adapter 10. In this embodiment, the first flexible insulating member 610 tightly covers the gap between the first cover 320 and the adapter body 100, and when the first cover 320 is opened at any angle relative to the adapter body 100, the first flexible insulating member 610 can cover the gap between the first cover 320 and the adapter body 100, so as to provide good and continuous insulation, block the path from the plug pin 200 to the user, and ensure that the first cover 320 is opened at any angle relative to the adapter body 100.

In one embodiment, the second flexible insulating member 620 is connected to the second cover 330 and the adaptor body 100, and is disposed corresponding to a gap between the second cover 330 and the adaptor body 100. Specifically, the second flexible insulating member 620 covers the gap between the second cover 330 and the adapter body 100 to cover the gap between the second cover 330 and the adapter body 100, so that the power of the pins 200 cannot pass through the gap at the connection position of the second flexible insulating member 620 and the adapter body 100 to be on the hand of the user, thereby improving the safety of the power adapter 10. In this embodiment, the second insulating member tightly covers the gap between the second cover 330 and the adapter body 100, and when the second cover 330 is opened at any angle relative to the adapter body 100, the second flexible insulating member 620 can be covered in the gap between the second cover 330 and the adapter body 100, so as to provide good and continuous insulation, block the path for the plug 200 to climb to the user, and ensure that the second cover 330 is opened at any angle relative to the adapter body 100.

Referring to fig. 4, and referring to fig. 5, fig. 6 and fig. 7, fig. 5 is a perspective view of the assembled power adapter of fig. 4; FIG. 6 is a schematic view of the power adapter of FIG. 5 from another angle; FIG. 7 is a cross-sectional view of the power adapter of FIG. 5 taken along line I-I. The first cover 320 includes a first interior trim 321 and a first exterior trim 322. The first exterior trimming part 322 is connected to the first interior trimming part 321, when the first cover 320 is in a closed state, the first interior trimming part 321 is adjacent to the pin 200 compared to the first exterior trimming part 322, when the first cover 320 is in an open state, the first interior trimming part 321 is deviated from the adapter body 100 compared to the first exterior trimming part 322, and one end of the first flexible insulating part 610 is clamped and fixed between the first interior trimming part 321 and the first exterior trimming part 322.

When the first cover 320 is in the closed state, the surface of the first exterior trimming part 322 facing away from the first interior trimming part 321 forms a part of the appearance surface of the power adapter 10. One end of the first flexible insulating member 610 is clamped and fixed to the first interior part 321 and the first exterior part 322, so that the first flexible insulating member 610 is firmly fixed in the first cover 320, and the first flexible insulating member 610 can be prevented from being easily torn down, and the safety of the power adapter 10 is improved. In the present embodiment, the first flexible insulating member 610 is interposed and fixed between the first interior member 321 and the first exterior member 322, and when the first cover 320 is in the closed state, the first flexible insulating member 610 is not visible from the outer surface of the power adapter 10, thereby ensuring the uniformity of the outer appearance of the power adapter 10.

Accordingly, the second cover 330 includes a second interior trim 331 and a second exterior trim 332. The second exterior trimming part 332 is connected to the second interior trimming part 331, when the second cover 330 is in the closed state, the second interior trimming part 331 is closer to the pin 200 than the second exterior trimming part 332 is, when the second cover 330 is in the open state, the second interior trimming part 331 is farther from the adapter body 100 than the second exterior trimming part 332 is, and one end of the second flexible insulating part 620 is sandwiched and fixed between the second interior trimming part 331 and the second exterior trimming part 332.

When the second cover 330 is in the closed state, a surface of the second exterior trim 332 facing away from the second interior trim 331 forms a part of an appearance surface of the power adapter 10. One end of the second flexible insulating member 620 is clamped and fixed between the second interior trim part 331 and the second exterior trim part 332, so that the second flexible insulating member 620 is more firmly fixed in the second cover 330, and the second flexible insulating member 620 can be prevented from being easily torn down, thereby improving the safety of the power adapter 10. In the present embodiment, the first flexible insulating member 610 is interposed and fixed between the first interior member 321 and the first exterior member 322, and when the first cover 320 is in the closed state, the first flexible insulating member 610 is not visible from the outer surface of the power adapter 10, thereby ensuring the uniformity of the outer appearance of the power adapter 10.

Referring to fig. 8 and 9 together, fig. 8 is a cross-sectional view of the power adapter shown in fig. 3 along line II-II; fig. 9 is a cross-sectional view of the power adapter shown in fig. 2 taken along line III-III. In fig. 8, the first cover 320 and the second cover 330 are both in an open state. In fig. 9, the first cover 320 and the second cover 330 are both in a closed state. As can be seen from fig. 7 and 8, when the first cover 320 and the second cover 330 are in the half-opened and opened states, the first flexible insulating member 610 covers the gap between the first cover 320 and the adapter body 100, and the second flexible insulating member 620 covers the gap between the second cover 330 and the adapter body 100; when the first cover 320 and the second cover 330 are both in the closed state, the first flexible insulating member 610 and the second flexible insulating member 620 are not visible from the outer surface of the power adapter 10, so that the consistency of the appearance of the power adapter 10 is ensured.

With continued reference to fig. 4 to 9, in one embodiment, the power adapter 10 further includes a first magnetic element 710 and a second magnetic element 720. The first magnetic member 710 is disposed in the accommodating space formed by the first interior trim part 321 and the first exterior trim part 322. The second magnetic member 720 is disposed in the accommodating space formed by the second interior trim 331 and the second exterior trim 332, when the first cover 320 and the second cover 330 are both in a closed state, the first cover 320 and the second cover 330 are fixed by the magnetic force between the first magnetic member 710 and the second magnetic member 720, and when the first cover 320 and the second cover 330 are both in an open state, the first cover 320 and the second cover 330 are fixed by the magnetic force between the first magnetic member 710 and the second magnetic member 720.

Specifically, the first magnetic member 710 includes a first magnetic pole and a second magnetic pole, and the second magnetic member 720 also includes a first magnetic pole and a second magnetic pole. Wherein the first magnetic pole is an N pole, and the second magnetic pole is an S pole; alternatively, the first magnetic pole is an S pole, and the second magnetic pole is an N pole. When the first cover 320 and the second cover 330 are both in the closed state, the first magnetic pole of the first magnetic member 710 faces the second magnetic pole of the second magnetic member 720, so that a magnetic attraction force is generated between the first magnetic member 710 and the second magnetic member 720, thereby fixing the first cover 320 and the second cover 330 together and not easily separating.

The first magnetic member 710 may be, but is not limited to, a permanent magnet or an electromagnet, and accordingly, the second magnetic member 720 may be, but is not limited to, a permanent magnet or an electromagnet. In this embodiment, the first magnetic member 710 is a magnet, and the second magnetic member 720 is also a magnet.

When the first cover 320 and the second cover 330 are both in the closed state and a pushing force is applied to the first cover 320, so that the first cover 320 rotates relative to the adapter body 100, due to the magnetic force between the first magnetic member 710 and the second magnetic member 720, the rotation of the first cover 320 will also drive the second cover 330 to rotate until the first cover 320 is in the open state and does not move, and the second cover 330 is in the open state and does not move. When the first cover 320 and the second cover 330 are both in the open state, the magnetic force between the first magnetic member 710 and the second magnetic member 720 makes the first cover 320 and the second cover 330 respectively fixed to two opposite sides of the adapter body 100.

Accordingly, when the first cover 320 and the second cover 330 are both in the open state and the first cover 320 is pushed to rotate the first cover 320 relative to the adapter body 100, due to the magnetic force between the first magnetic member 710 and the second magnetic member 720, the rotation of the first cover 320 will drive the second cover 330 to rotate until the first cover 320 is in the closed state and does not move, and the second cover 330 is also in the closed state and does not move. When the first cover 320 and the second cover 330 are both in the closed state, the magnetic force between the first magnetic member 710 and the second magnetic member 720 makes the first cover 320 and the second cover 330 fixed on two opposite sides of the adapter body 100.

When a pushing force is applied to the first cover 320 so that the first cover 320 rotates relative to the adapter body, due to the magnetic force between the first magnetic member 710 and the second magnetic member 720, the rotation of the first cover 320 drives the second cover 330 to rotate relative to the adapter body 100. It can be understood that when a pushing force is applied to the second cover 330 to rotate the second cover 330 relative to the adapter body 100, the rotation of the second cover 330 will drive the first cover 320 to rotate due to the magnetic force between the first magnetic member 710 and the second magnetic member 720. In summary, due to the effects of the first magnetic member 710 and the second magnetic member 720, the synchronous movement between the first cover 320 and the second cover 330 can be achieved by applying a pushing force to any one of the first cover 320 and the second cover 330, so as to achieve the synchronous opening or the proportional closing of the first cover 320 and the second cover 330.

Referring to fig. 10 and 11, fig. 10 is a schematic diagram illustrating dimensions of components when a first cover and a second cover of a power adapter are in a closed state according to an embodiment of the present disclosure; fig. 11 is a schematic diagram illustrating dimensions of respective components in the power adapter shown in fig. 8 when the first cover and the second cover are in an open state.

In the present embodiment, the range of the thickness D1 of the adaptor body 100 is: d1 is not less than 6.3mm and not more than 14 mm; the thickness D2 of the first cover 320 ranges from: 4.825mm is not less than D2 is not less than 7mm, and the thickness D3 of the second cover body 330 is in the range of: d3 is not less than 4.825mm and not more than 7 mm.

Due to safety regulations, the width of the pins 200 is typically 6.3mm for a power adapter 10 suitable for use in china. Therefore, the D1 is more than or equal to 6.3 mm. In order to make the power adapter 10 thinner and lighter, the thickness D1 of the adapter body 100 is less than or equal to 14 mm.

In one embodiment, the thickness D1 of the adaptor body 100 ranges from: d1 is not less than 9.65mm and not more than 14 mm; the thickness D2 of the first cover 320 ranges from: d2 is not less than 4.825mm and not more than 7 mm; the thickness D3 of the second cover 330 ranges from: d3 is not less than 4.825mm and not more than 7 mm.

In one embodiment, the thickness D2 of the first cover 320 and the thickness D3 of the second cover 330 are equal, and the sum of the thickness D2 of the first cover 320 and the thickness D3 of the second cover 330 is equal to the thickness D1 of the adapter body 100.

The selection of the above dimensions is not arbitrary but is designed in combination with the requirements of safety regulations in the power adapter 10. Specifically, when the first cover 320 and the second cover 330 are both in the open state, the distance between the side surfaces of the pins 200 adjacent to the first cover 320 and the outermost surface of the first cover 320 is required to be greater than or equal to 6.5mm due to the requirement of safety regulations, so as to prevent the user from being injured by electricity leakage when the power adapter 10 is inserted into the socket 50 through the pins 200. Likewise, due to safety regulations, the side of the pins 200 adjacent to the second cover 330 must be spaced from the outermost surface of the second cover 330 by a distance greater than or equal to 6.5 mm. Since the width of the pin 200 is 6.3mm, also due to the requirements of safety regulations, the minimum value of the thickness D1 of the adapter body 100, the thickness D2 of the first cover 320, and the thickness D3 of the second cover 330 is 6.3mm +6.5mm +6.5 mm-19.3 mm. Then, when the sum of the thickness D2 of the first cover 320 and the thickness D3 of the second cover 330 is equal to the thickness D1 of the adaptor body 100, the minimum value of the thickness D1 of the adaptor body 100 is equal to 19.3 mm/2-9.65 mm. When the thickness of the first cover 320 is equal to that of the second cover 330, D2-D3-9.65 mm/2-4.825 mm. That is, the minimum value of the thickness of the first cover 320 is 4.825mm, and the minimum value of the thickness of the second cover 330 is 4.825 mm. Since the thickness of the adapter body 100 of the conventional power adapter 10 is usually greater than 14mm, in order to make the adapter body 100 of the power adapter 10 thinner, the upper limit of the adapter body 100 may be selected to be 14 mm. When the thicknesses of the first cover 320 and the second cover 330 are equal, and the sum of the thickness of the first cover 320 and the thickness of the second cover 330 is equal to the thickness of the adapter body 100, the upper limit of the thickness of the first cover 320 is 7mm, and the upper limit of the thickness of the second cover 330 is 7 mm.

When the discharging interface 800 is a USB interface, the USB interface may be, but is not limited to, a USB 2.0 interface, a USB 3.0 interface, or the like.

The adapter body 100 includes a housing 110 and a carrier 120, the housing 110 has an accommodating space 112, and the accommodating space 112 is used for accommodating the circuit board 150. The carrying seat 120 is used for carrying the pins 200, and the carrying seat 120 is disposed at the opening of the accommodating space 112.
