Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

Due to the continuous development of electronic devices such as mobile phones, power adapters corresponding to the electronic devices are also continuously developed and advanced. The electronic device is usually provided with a rechargeable battery, and the power adapter usually comprises an adapter body and pins, when the pins are inserted into the socket, the power adapter and the electronic device are electrically connected through a charging wire, so that the rechargeable battery is charged.

At present power adapter is constantly developing towards the trend of miniaturization, but the power adapter who constantly reduces can lead to participating in the edge that is close to adapter body and the continuous distance that reduces between adapter body's the periphery side, when being less than the certain distance, power adapter is at the in-process that charges this moment, when the user finger touches the periphery side of adapter body, will lead to creepage distance short excessively, make the electric energy on participating in pass through adapter body and transmit to the user finger on, lead to the electric leakage, thereby cause the injury to the user. Therefore, there is a need for a power adapter that is small in size and can prevent current leakage.

In view of the above, in order to solve the above problems, the present application provides a power adapter. Referring to fig. 1 to 5, fig. 1 is a schematic diagram illustrating an application environment of a power adapter according to an embodiment of the present application. Fig. 2 is a schematic perspective view of a power adapter in a closed state according to an embodiment of the present application. Fig. 3 is a schematic perspective view illustrating a power adapter in an open state according to an embodiment of the present application. Fig. 4 is a schematic cross-sectional view of a power adapter with a cover removed according to an embodiment of the present application. Fig. 5 is a schematic cross-sectional view illustrating a power adapter in an open state according to an embodiment of the present application. The present embodiment provides a power adapter 1, the power adapter 1 has a closed state and an open state, and specifically, the power adapter 1 includes an adapter body 10, a pin assembly 20, and a cover 30. The adapter body 10 has a receiving space 11. The pin assembly 20 comprises pins 21 and a bracket 22, at least a part of the bracket 22 is arranged in the accommodating space 11, and the bracket 22 comprises a connecting end 220; the pin 21 includes a first portion 211 and a second portion 212 connected to each other, the first portion 211 is closer to the connection end 220 than the second portion 212, the first portion 211 is connected to the connection end 220, and an outer periphery of the first portion 211 is insulative. The cover 30 is rotatably connected to the bracket 22, when the power adapter 1 is in the open state, the cover 30 is disposed on the surface of the connecting end 220 close to the pins 21, the cover 30 and the connecting end 220 enclose a shielding space 31, and the first portion 211 is disposed in the shielding space 31.

The power adapter 1 according to the present embodiment is a conversion device that supplies power to the electronic device 2. Generally, the power adapter 1 can convert an alternating voltage into a direct voltage. For example, as shown in fig. 1, the power adapter 1 is plugged into a socket 3, receives an ac voltage output by the socket 3, and converts the received ac voltage into a dc voltage, which is used to charge an electronic device 2 that uses electricity, such as a mobile phone and a computer. It is to be understood that in other embodiments, the power adapter 1 converts the received ac voltage to a dc voltage that is directly available to the electronic components in the electronic device 2. It should be understood that the schematic diagram of the application environment of the power adapter 1 is only helpful for understanding the application of the power adapter 1, and should not be construed as limiting the power adapter 1 provided in the present application.

In addition, the electronic device 2 referred to in the present embodiment generally includes, but is not limited to, mobile terminals such as a mobile phone, a tablet Computer, a notebook Computer, a palm top Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, and a pedometer, and fixed terminals such as a Digital TV and a desktop Computer. The electronic device 2 is taken as a mobile phone for illustration.

In addition, the power adapter 1 has an open state and also has a closed state corresponding to the open state, meaning that the power adapter 1 does not have only one shape, it is movable, that is, closed and opened, and the closing and opening causes the pins 21 to be hidden and the pins 21 to be exposed. As for the specific state, the present application will be explained below.

The power adapter 1 according to the present embodiment includes an adapter body 10. Wherein the adapter body 10 can be understood as a lower cover of the power adapter 1, and structural members for protecting and installing the power adapter 1, such as various structural members, can be disposed in the receiving space 11 of the adapter body 10. The receiving space 11 is defined by a side wall of the adapter body 10, for example, the side wall of the adapter body 10 is defined by a circle to define the receiving space 11. However, the application is not limited as to whether the adapter body 10 has a bottom wall.

The power adapter 1 of the present embodiment further includes a pin assembly 20, and the pin assembly 20 includes a pin 21 and a bracket 22 connected to each other. Wherein the pin assembly 20 is composed of a bracket 22 and a pin 21. The pins 21 are attached to the bracket 22. The end of the pin 21 that is connected to the bracket 22 may be named a connection end 220 at this time, i.e., the pin 21 is connected to the connection end 220. The designation of the connection end 220 helps to provide a clearer picture of the subsequent structure.

Secondly, at least part of the pins 21 are made of conductive metal, and the pins 21 are inserted into the socket 3 and used for receiving alternating voltage provided by the socket 3. The number of the pins 21 may be, but not limited to, two, and in the present embodiment, the number of the pins 21 is two. The two pins 21 are arranged oppositely and at intervals. The pins 21 may be, but are not limited to, elongated shapes. The end of the pin 21 facing away from the body of the socket 3 is curved to facilitate insertion of the pin 21 into the socket 3. When the pin 21 is inserted into the socket 3 to receive a first voltage, the circuit board is electrically connected to the pin 21 to receive the first voltage transmitted from the pin 21, and the circuit board is used to convert the first voltage into a second voltage, and the second voltage is used to charge the battery. The support 22 is a structure for disposing the pins 21, and other structural members may be disposed in the support 22, which is not described herein again.

In addition, when the power adapter 1 is in the closed state, the pins 21 are covered, including but not limited to the following cases: the pins 21 are covered by the cover 30; alternatively, the pins 21 are covered by the adapter body 10; alternatively, the pins 21 are covered by both the adapter body 10 and the cover 30. The case where the pins 21 are covered by the cover 30 is exemplified by the case where the cover 30 has receiving cavities in which the pins 21 are received when the cover 30 is closed, so as to cover the pins 21. The case where the plug pins 21 are covered by the adapter body 10 is exemplified by the case where the adapter body 10 has a housing cavity, and when the cover 30 is closed, the plug pins 21 are housed back in the housing cavity, and in this case, the plug pins 21 are covered by the adapter body 10. The plug pins 21 are covered by both the adapter body 10 and the cover 30, for example, the adapter body 10 and the cover 30 together form a receiving cavity, and when the cover 30 is closed, the plug pins 21 are received in the receiving cavity formed by both the adapter body 10 and the cover 30. The present application is illustrated with the pins 21 covered by the cover 30.

In addition, when the power adapter 1 is in the open state, at least a part of the pins 21 are disposed outside the receiving space 11. When the power adapter 1 is in the closed state, any situation may be adopted, but when the power adapter 1 is in the open state, at least part of the pins 21 are ensured to be arranged outside the accommodating space 11, so that the pins 21 can be inserted into the sockets 3.

As known in the prior art, the pins 21 are connected by the brackets 22, the brackets 22 are disposed in the receiving spaces 11, and the side edges of the brackets 22 are the adapter bodies 10, and as can be seen from the above description, when the power adapter 1 is in the half-open state, the cover 30 does not abut against the adapter bodies 10 yet, and at this time, for convenience of rotation, the cover 30 usually has a gap with the adapter bodies 10. When the user touches the surface of the adapter body 10 inserted into the socket 3, especially the surface of the adapter body 10 near the pins 21, the creepage distance of the power adapter 1 is short. Here, the creepage distance refers to a length of a path taken by current from a side of the pin 21 close to the adapter body 10 to the outer peripheral side surface of the adapter body 10. However, since the cover 30 has a gap between the cover 30 and the adapter body when the cover 30 is rotatably connected to the adapter body 10, that is, when the cover is in the open state or the closed state, the current can be directly transmitted from the connection position of the pin 21 and the bracket 22 to the outer peripheral side of the adapter body 10, and the creepage distance is changed, and at this time, the creepage distance is the distance from the side of the pin 21 close to the adapter body 10 to the outer peripheral side, and the distance is too small and is far smaller than the preset safety distance, which may cause injury to the user.

Therefore, the present embodiment divides the pin 21 into two parts, i.e., the pin 21 includes the first part 211 and the second part 212 connected. The first portion 211 and the second portion 212 are a unitary structure. And the first portion 211 is closer to the connection end 220 than the second portion 212, and the first portion 211 connects the connection end 220. It will also be appreciated that the first portion 211 is a structure that is proximal to the bracket 22, while the second portion 212 is a structure that is distal from the bracket 22, with the first portion 211 being attached to the attachment end 220 of the bracket 22. The connecting end 220 can also be understood as the end of the bracket 22 which is exposed and can be used for seeing after being arranged in the accommodating space 11. In order to solve the above problem, in the present embodiment, the outer peripheral edge of the first portion 211 may have an insulating property. I.e., the outer surface of the first portion 211 is insulated and non-conductive. Since the second portion 212 is to be inserted into the socket 3, the outer circumference of the second portion 212 is electrically conductive. In this way, when the pin 21 is received in the socket 3 and the adapter body 10 is touched by the user, the current is transmitted not from the connection between the pin 21 and the connection end 220 of the holder 22, that is, from the connection between the first portion 211 and the connection end 220 of the holder 22, but from the connection between the second portion 212 and the first portion 211. The current is transmitted from the junction of the second portion 212 and the first portion 211 to the junction of the first portion 211 and the connection terminal 220, and then transmitted from the connection terminal 220 to the outer peripheral side surface of the adapter body 10.

(as shown by L1 in fig. 4).

In summary, compared with the related art, the power adapter 1 provided in the embodiment increases the distance of current transmission, that is, the distance of the height of the first portion 211 is increased, so as to increase the creepage distance, which can reach 9.35mm and is much longer than a preset safety distance (for example, 6.5mm), thereby improving the safety performance of the power adapter 1, and preventing the pins 21 from leaking electricity when being inserted into the socket 3 and causing injury to the user.

The first portion 211 is not limited to the insulating material, and the present application will be described in detail later.

In addition, the power adapter 1 according to the present embodiment includes the cover 30 in addition to the above configuration. The cover 30 is rotatably connected to the bracket 22, i.e., the cover 30 can rotate relative to the bracket 22. In the present embodiment, the number of the cover bodies 30 is two, and when the power adapter 1 is in the closed state, the two cover bodies 30 are connected to hide the pins 21, and at this time, the power adapter 1 is flat, has a small thickness, and is an ultra-thin adapter. When the power adapter 1 is in the open state, the two cover bodies 30 rotate relatively, and the surfaces of the two cover bodies 30 on the sides away from the bracket 22 jointly form the plugging surface of the power adapter 1.

As can be seen from the above, the pin 21 is hidden and exposed by the rotation of the cover 30 in this embodiment. And the creepage distance is increased because the present embodiment makes the outer peripheral edge of the first portion 211 insulating. In this embodiment, the position of the cover 30 after being rotated can be adjusted, that is, when the power adapter 1 is in the open state, it can also be understood that when the cover 30 is rotated to the end position, the cover 30 is disposed on the surface of the connecting end 220 near the plug pins 21, and the cover 30 and the connecting end 220 enclose a shielding space 31, and the first portion 211 is disposed in the shielding space 31.

In other words, the position of the cover 30 after rotation is adjusted, so that the cover 30 is still disposed on the surface of the connecting end 220 close to the pins 21 after rotation, i.e. the upper surface of the connecting end 220 in fig. 5, and the shielding space 31 formed by the cover 30 and the bracket 22 can shield the first portion 211 due to the change of the position of the cover 30. Since national standards do not allow the exposed pins 21 to have insulation, the exposed pins 21 must be electrically conductive. Therefore, in the present embodiment, only the conductive second portion 212 protrudes from the cover 30, i.e., is exposed outside, and the first portion 211 with an insulated outer periphery is hidden, i.e., the creepage distance is increased, and the national standard of China is met.

Alternatively, when the power adapter 1 is in the open state, the height of the pins 21 protruding from the cover 30 is 16 ± 0.35cm, i.e., the height of the pins 21 protruding from the cover 30 in the present embodiment satisfies the above-mentioned dimensions, so as to meet the national standard. However, in the present embodiment, the pins 21 include portions protruding from the cover 30 and portions disposed in the shielding space 31, and therefore, the actual height of the pins 21 in the present embodiment should be the sum of the height of the pins 21 protruding from the cover 30 and the height of the pins 21 disposed in the shielding space 31, and it should also be understood that the height of the shielding space 31 is the thickness of the cover 30 along the direction away from the connection end 220, and therefore, the actual height of the pins 21 in the present embodiment may be the sum of the height of the pins 21 protruding from the cover 30 and the thickness of the cover 30.

Alternatively, the width of the pin 21 is 6.29 ± 0.11cm, the thickness of the pin 21 is 1.45 ± 0.05cm, and the distance between two adjacent pins 21 is 12.7 ± 0.135 cm.

Referring to fig. 5 again, in this embodiment, when the power adapter 1 is in the open state, a surface of the first portion 211 facing away from the bracket 22 is flush with a surface of the cover 30 facing away from the bracket 22, and the second portion 212 is disposed outside the shielding space 31.

In this embodiment, a surface of the first portion 211 facing away from the bracket 22 may be flush with a surface of the cover 30 facing away from the bracket 22, and the second portion 212 is disposed outside the shielding space 31. It is also understood that the first portion 211 is disposed inside the shielded space 31 and the second portion 212 is disposed outside the shielded space 31. Alternatively, the interface of the first portion 211 and the second portion 212 is flush with the surface of the cover 30 on the side facing away from the bracket 22. The height of the first portion 211 is the thickness of the cover 30, so that the height of the exposed pins 21 can be further increased.

The above mentioned that the present embodiment increases the creepage distance by making the outer peripheral edge of the first portion 211 insulating. But the above object can be achieved in a number of ways in the present application. Since the pins 21 are required to be conductive and the outer periphery of the first portion 211 is required to be insulating, the first portion 211 necessarily includes both conductivity and insulation. For example, this application provides two specific implementations. In one implementation, the present application may coat the outer circumference of the conductor on the side near the connection end 220 with an insulating glue, thereby forming the first portion 211 to be insulating. In a second implementation form of the method,

referring to fig. 6, fig. 6 is an exploded view of a pin assembly according to an embodiment of the present application. In this embodiment, the first portion 211 includes a conductive portion 2111 and an insulating portion 2112, the conductive portion 2111 is connected to the second portion 212, the insulating portion 2112 is connected to the connection terminal 220, the insulating portion 2112 is provided with a housing groove 2113, and the conductive portion 2111 is provided in the housing groove 2113.

In this embodiment, the insulating portion 2112 is prepared, the connecting terminal 220 is connected to the insulating portion 2112, the accommodating groove 2113 is formed in the insulating portion 2112, and the conductive portion 2111 is provided in the accommodating groove 2113, so that the insulating portion 2112 and the conductive portion 2111 together form the first portion 211, and the outer periphery of the first portion 211 is insulated, that is, the insulating portion 2112 is insulated.

Alternatively, the insulation portion 2112, the pin 21 and the bracket 22 are of an integral structure, that is, the insulation portion 2112, the pin 21 and the bracket 22 are prepared by the same process, for example, the integral insulation portion 2112, the pin 21 and the bracket 22 can be prepared by insert molding.

Referring to fig. 4 to 5 again, in the present embodiment, the second portion 212 protrudes along the radial direction of the first portion 211, and the second portion 212, the first portion 211, and the connecting end 220 enclose an avoiding space 23.

In the present embodiment, the second portion 212 may be protruded along the radial direction of the first portion 211, and it is also understood that the width of the second portion 212 is larger than that of the first portion 211, that is, the pin 21 has a structure of being "wide at the top and narrow at the bottom". This allows the second portion 212, the first portion 211, and the connecting end 220 to define an escape space 23. Because the cover 30 rotates in the process from the closed state to the open state, and the cover 30 is still disposed on one side of the connecting end 220 close to the pins 21 after the rotation is finished, and the cover 30 rotates from the vertical state to the horizontal state, in the rotating process, one end of the cover 30 close to the bracket 22 rotates to a position where the cover 30 is close to the pins 21, and at this time, the design of the avoiding space 23 affects the rotation of the cover 30, so that a rotating space is reserved for the rotation of the cover 30 in advance.

After the rotation of the cover 30 is completed, that is, when the power adapter 1 is in the open state, the cover 30 may have various positional relationships and connection relationships with the pins 21. Referring to fig. 7, fig. 7 is a schematic perspective view illustrating a power adapter in an open state according to another embodiment of the present application. In this embodiment, an accommodating groove 32 is formed on one side of the cover 30 close to the plug pins 21, the power adapter 1 further has a closed state, and when the power adapter 1 is in the closed state, the plug pins 21 are arranged in the accommodating groove 32; when the power adapter 1 is in the open state, the pins 21 are opposite to the accommodating grooves 32, and the cover 30 and the pins 21 are arranged in a gap.

In an embodiment of the present application, a side of the cover 30 close to the pins 21 is provided with receiving grooves 32, and the receiving grooves 32 are used for the pins 21 to be disposed in the receiving grooves 32 when the power adapter 1 is in the closed state, so as to hide the pins 21 and connect the two covers 30. When the power adapter 1 is in the open state, although the receiving groove 32 is away from the plug 21, the plug 21 can be opposite to the receiving groove 32, and the cover 30 and the plug 21 are disposed in a gap. Thus, the pins 21 do not interfere with the rotation of the cover 30, so that the cover 30 continues to rotate.

Referring to fig. 5 again, in the present embodiment, when the power adapter 1 is in the open state, the cover 30 abuts against a surface of the second portion 212 on a side close to the first portion 211.

In another embodiment of the present invention, when the power adapter 1 is in the open state, the end of the cover 30 that is close to the bracket 22 may not only be rotated to be close to the pins 21 and be disposed in the receiving space 11, but also abut against the surface of the second portion 212 that is close to the first portion 211, that is, abut against the lower surface of the second portion 212 that protrudes from the first portion 211. This surface is used to limit the rotation of the cover 30, and the cover 30 stops rotating.

Alternatively, in this embodiment, when the power adapter 1 is in the open state, an included angle between an end surface of the cover 30 facing away from the adapter body 10 and the peripheral side surface of the second portion 212 is greater than or equal to 90 °.

In this embodiment, an included angle between an end surface of the cover 30 facing away from the adapter body 10 and the peripheral side surface of the second portion 212 may be greater than or equal to 90 °, so that the pins 21 and the sockets 3 can be effectively connected after the power adapter 1 is opened.

Further alternatively, the angle between the end surface of the cover 30 facing away from the adapter body 10 and the peripheral side surface of the second portion 212 is 90 °, i.e. the end surface of the cover 30 facing away from the adapter body 10 is horizontal, which allows better insertion of the pins 21 into the sockets 3.

As for how to control the included angle between the end surface of the cover 30 away from the adapter body 10 and the peripheral side surface of the second portion 212, for the first embodiment, the damping structure may be provided at the rotational connection position of the cover 30 and the bracket 22, or a magnetic member or other components may be added for control. For the second embodiment, the second portion 212 may protrude from the lower surface of the first portion 211 to limit the position of the upper surface of the cover 30 away from the bracket 22.

Referring to fig. 8, fig. 8 is an exploded view of a power adapter according to an embodiment of the present application. In this embodiment, the power adapter 1 further includes a rotating shaft 40, and the rotating shaft 40 is disposed on a side of the connecting end 220 close to the pins 21.

The above mentioned cover 30 rotates the connecting bracket 22, and when the power adapter 1 is in the open state, the cover 30 is disposed on the surface of the connecting end 220 close to the pins 21. This embodiment therefore provides a specific implementation. A rotating shaft 40 may be additionally provided, and the rotating shaft 40 is disposed at a side of the connecting end 220 close to the pins 21, so that the cover 30 is rotatably connected to a side of the connecting end 220 close to the pins 21. When the cover 30 is rotated, the cover 30 is disposed on the surface of the connecting end 220 near the pins 21, so as to form a shielding space 31 to hide the first portion 211.

As for the specific structure of the rotating shaft 40, the present embodiment is not limited thereto.

Alternatively, in this embodiment, the bracket 22, the insulating portion 2112, the pin 21, and the rotating shaft 40 are formed in an integrated structure.
