Abstract

A counterweight-type adapter socket structure includes a housing extending along a first direction, comprising a receiving space, an AC power socket area, and a DC power socket area. The receiving space is divided into a first receiving area and a second receiving area along the first direction, with the AC power socket area located between the first and second receiving areas. A power pin is disposed on the housing, with the first and second receiving areas located on opposite sides of the power pin along the first direction. A first circuit board is fixed to the first receiving area. A second circuit board is fixed to the second receiving area and includes at least one DC power output port corresponding to the DC power socket area, and the second circuit board is electrically connected to the first circuit board. An AC power conductive plate is disposed in the receiving space at a position corresponding to the AC power socket area, and is directly or indirectly electrically connected to the power pin. This structure aims to distribute the weight of the internal electronic components to both sides, avoiding excessive sway of the adapter socket due to weight concentration on the same side of the pin.

Description

Technical Field

[0001] This invention relates to a counterweight adapter socket structure, specifically an invention that arranges internally installed electronic components on a first circuit board and a second circuit board, and respectively positions the first circuit board and the second circuit board on both sides of the plug, so that the weight of the electronic components is distributed on both sides, thereby making the counterweight of the adapter socket more even. Background Technology

[0002] Common household power supplies include 110V or 220V AC power. However, most portable electronic devices, such as smartwatches, mobile phones, tablets, laptops, and handheld game consoles, are equipped with rechargeable batteries and are no longer limited to being connected to an AC wall socket when in use. When charging these portable electronic devices, a charger is often connected to the wall socket. The charger converts the AC voltage supplied by the wall socket into DC voltage, and then outputs DC voltage from the charger's DC output port, such as a Type A USB port or a Type C USB port, to power the portable electronic device.

[0003] To enable the adapter socket to provide both DC and AC voltages simultaneously, both DC and AC output ports are provided on the adapter socket. For example, the People's Republic of China Patent Publication No. CN206962155U, entitled "A Power Socket with DC Charging and AC Socket Functions," includes at least one socket body. The socket body has a hexahedral structure, with a power input interface and a power output interface electrically connected to each other on two opposite sides along the length of the socket body. An output slot is provided on at least one of the four sides surrounding the length of the socket body, and the output slot is electrically connected to the power input interface. An AC / DC conversion unit is provided inside the socket body.

[0004] However, in the aforementioned adapter socket, the power input and power output interfaces are located on opposite sides. The power input interface is plugged into the wall socket via pins. When an external plug is connected to the power output interface, the weight of the plug and the connected wire will generate torque on the power input interface, causing the aforementioned extension cord or adapter socket to sway downwards relative to the wall socket. Over time, this can cause the wall socket's pin clips to loosen, making it unable to maintain the required clamping force. If left unattended or used continuously, the insufficient clamping force of the pin clips when using the aforementioned extension cord or adapter socket may result in an excessively small contact point, leading to overheating and damage to the aforementioned device.

[0005] The People's Republic of China Patent Publication No. CN201466427U, entitled "A Multifunctional Socket", includes a base with an AC power socket and a USB socket.

[0006] The "Socket with Lighting and USB Interface" patent publication number CN201541034U of the People's Republic of China comprises a box-shaped structure consisting of a lampshade and a housing that are movably connected to each other. The lampshade contains a mounting plate and a plurality of LED lights, and the lampshade is equipped with a switch connected to the electrodes of the LED lights. The panel is provided with a plurality of sockets and USB interfaces arranged in sequence, and a plurality of switches are arranged in sequence parallel to the sockets and interfaces. Each switch controls the power supply of a socket and interface parallel to the switch. A plug is fixed on the base plate, and an AC / DC conversion circuit is provided in the cavity. Its input end is connected to an AC power supply, and its output end is connected to one or more USB interfaces.

[0007] The People's Republic of China Patent Publication No. CN213936807U, entitled "A Adapter-Type Multifunctional Socket," comprises: a movable plug and a fixed socket. The fixed socket has an insertion slot on the back of its front end, and three contact terminals on the rear side of the insertion slot. A high-voltage AC socket is located at the front end inside the fixed socket, and socket terminals are located inside the high-voltage AC socket. The socket terminals are electrically connected to the contact terminals, and a corresponding socket through hole is provided on the fixed socket. A conversion circuit board is located at the rear end inside the fixed socket, and the conversion circuit board is electrically connected to the contact terminals. A USB socket is located on the conversion circuit board, and a corresponding USB socket through hole is provided on the fixed socket. The movable plug is embedded in the insertion slot of the fixed socket. A power-connecting prong is located on the back of the movable plug, and an embedded notch is located at the lower end of the front of the movable plug, with a terminal clip located within the notch.

[0008] However, in the aforementioned cases, the prongs are all located near one side of the adapter socket, while the DC power socket area and / or AC power socket area are located away from the prongs and on the other side of the adapter socket. When a DC power socket area is provided, high-voltage to low-voltage and DC output electronic components must be installed inside the adapter socket. Generally, electronic components have weight, and this weight increases with the wattage supplied. Therefore, the adapter socket also suffers from an unbalanced weight distribution, leading to the problem of the wall socket's prong clips loosening over long-term use.

[0009] To more clearly illustrate the problems caused by the unbalanced weight distribution in the previous adapter socket, please refer to [link / reference]. Figure 11 , Figure 12 and Figure 13In the above configuration, due to the uneven weight distribution of adapter socket A, the center of gravity is biased towards the electronic components, i.e., the AC socket area B or DC socket area C. When adapter socket A is used, and the wall socket D is inserted through pin A1, adapter socket A will tilt due to its own center of gravity, generating a torque at the connection point of pin A1 into wall socket D. Over prolonged use, this will cause pin A1 to widen the clamping gap of the internal pin clips of wall socket D, thus preventing the internal pin clips of wall socket D from providing the required clamping force.

[0010] Furthermore, in addition to the problem of uneven weight distribution in adapter socket A itself, when many electrical plugs are connected to adapter socket A, but the plugs are all far from the pin A1 of adapter socket A, the weight of the plugs plus the wires will also generate torque on the connection point of pin A1 when it is inserted into the wall socket D, which will make the aforementioned swaying of adapter socket A more serious. Summary of the Invention

[0011] Therefore, the purpose of this invention is to prevent the adapter socket from wobbling due to uneven weight distribution when installed on a wall socket, and to prevent the wall socket from loosening due to failure to maintain the specified clamping force during long-term use, and to propose a weighted adapter socket structure.

[0012] This invention provides a counterweight-type adapter socket structure, comprising:

[0013] A housing extending along a first direction includes a receiving space, an AC power socket area, and a DC power socket area. The receiving space is divided into a first receiving area and a second receiving area along the first direction, and the AC power socket area is located between the first receiving area and the second receiving area. A power plug is disposed in the housing, and the first receiving area and the second receiving area are respectively located on opposite sides of the power plug in the first direction. A first circuit board is fixed to the first receiving area. A second circuit board is fixed to the second receiving area and includes at least one DC power output port corresponding to the DC power socket area. The second circuit board is electrically connected to the first circuit board. An AC conductive plate is disposed in the receiving space at a position corresponding to the AC power socket area, and the AC conductive plate is directly or indirectly electrically connected to the power plug.

[0014] Furthermore, the power plug includes a live wire plug and a neutral wire plug, and the AC conductive plate includes a live wire conductive plate and a neutral wire conductive plate. The live wire conductive plate is directly connected to the live wire plug, and the neutral wire conductive plate is directly connected to the neutral wire plug. The live wire conductive plate includes a first live wire slot, and the neutral wire conductive plate includes a first neutral wire slot. The housing has a first live wire socket corresponding to the first live wire slot, and the housing has a first neutral wire socket corresponding to the first neutral wire slot.

[0015] Furthermore, the housing includes a front and a back, with the power plug located on the back and the first live wire socket and the first neutral wire socket located on the front.

[0016] Furthermore, the AC conductive sheet includes a grounding conductive sheet, which is electrically connected to a grounding screw. The grounding screw is disposed in the housing, and the housing has a grounding socket corresponding to the grounding conductive sheet, which is located on the front side.

[0017] Furthermore, the housing includes a side surface located between the front and the back surfaces. The live wire conductive sheet includes a second live wire slot, the neutral wire conductive sheet includes a second neutral wire slot, the housing has a second live wire socket corresponding to the second live wire slot, and the housing has a second neutral wire socket corresponding to the second neutral wire slot. The second live wire socket and the second neutral wire socket are located on the side surface.

[0018] Furthermore, the DC socket area is located on one side of the AC socket area in the first direction.

[0019] Furthermore, the DC power socket area is located on opposite sides of the AC power socket area in the first direction.

[0020] Furthermore, the housing is provided with a DC power socket corresponding to the DC power output port.

[0021] Furthermore, it includes a switch disposed in the housing, the switch being electrically connected between the power plug and the AC conductive plate.

[0022] The following effects can be achieved based on the above technical features:

[0023] 1. The first circuit board and the second circuit board are respectively disposed in the first receiving area and the second receiving area. The weight of the first circuit board and the second circuit board can be distributed on both sides of the power plug. When the adapter is connected to the wall socket through the power plug, the weight is distributed on both sides, so the weight distribution of the adapter is more even. This can avoid the weight being concentrated on the same side of the power plug, thus preventing the adapter from swinging too much.

[0024] 2. The AC socket area is located between the first and second receiving areas. When an external power plug is connected to the AC socket area, it can prevent the weight of the power plug and cord from being biased to one side, thus avoiding excessive swing of the adapter socket.

[0025] 3. The adapter socket is equipped with both DC and AC power socket areas, which can provide both DC and AC voltages simultaneously.

[0026] 4. When the DC power socket area is in use, because the DC power socket area is located on opposite sides of the power plug, the weight of the connected wires will not be concentrated on the same side of the power plug, thus avoiding excessive sway of the adapter socket.

[0027] 5. The AC socket area has power outlets on both the front and sides. When the adapter is connected to the wall socket, an additional set of power outlets can be used. Attached Figure Description

[0042] Based on the above technical features, the main functions of the counterweight-type adapter socket structure of the present invention will be clearly demonstrated in the following embodiments.

[0043] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The counterweight-type adapter socket of the present invention comprises a housing 1, a conductive plate base 2, a first circuit board 3, a second circuit board 4, a power plug 5, an AC conductive plate 6, a grounding screw 7, and a switch 8.

[0044] The housing 1 extends along a first direction D1 and includes a receiving space 11, an AC power socket area 12, and a DC power socket area 13. The receiving space 11 is divided along the first direction D1 into a first receiving area 111 and a second receiving area 112. The AC power socket area 12 is located between the first receiving area 111 and the second receiving area 112. The DC power socket area 13 is located on one side of the AC power socket area 12 along the first direction D1. Specifically, the housing 1 has a front 14, a back 15, and a side 16. It is composed of an upper housing 1A and a lower housing 1B. The front side 14 is located on the upper housing 1A, and the back side 15 is located on the lower housing 1B. The upper housing 1A covers the lower housing 1B to form the receiving space 11. The side side 16 is located between the front side 14 and the back side 15. The housing 1 has a first live wire socket 141, a first neutral wire socket 142, a ground wire socket 143 and a plurality of DC power sockets 144 on the front side 14, and a second live wire socket 161 and a second neutral wire socket 162 on the side side 16.

[0045] The conductive plate holder 2 is disposed in the receiving space 11 at a position corresponding to the AC socket area 12. The conductive plate holder 2 has a live wire receiving area 21, a neutral wire receiving area 22 and a ground wire receiving area 23. The live wire receiving area 21 and the neutral wire receiving area 22 are disposed on opposite sides of the ground wire receiving area 23 along the first direction D1.

[0046] The first circuit board 3 is fixed to the first receiving area 111, and the second circuit board 4 is fixed to the second receiving area 112. The second circuit board 4 includes a plurality of DC output ports 41, which are positioned corresponding to the DC socket area 13 and the aforementioned DC socket 144. The second circuit board 4 is electrically connected to the first circuit board 3. Specifically, in this embodiment, the first circuit board 3 has the function of converting AC voltage into DC voltage and includes various electronic components such as rectifiers, capacitors, resistors, and inductors. The second circuit board 4 has the function of outputting DC voltage and includes the aforementioned DC output ports 41 and integrated circuits (ICs). The aforementioned DC output ports 41 include two USB Type-C connectors and two USB Type-A connectors. However, the configuration of electronic components in the first circuit board 3 and the second circuit board 4 is not limited to this. For example, the first circuit board 3 and the second circuit board 4 can also be two completely identical circuit boards, each having an AC / DC conversion circuit and a DC output control circuit, and each having a DC output port 41.

[0047] The power plug 5 is disposed on the housing 1, and the first receiving area 111 and the second receiving area 112 are respectively located on opposite sides of the power plug 5 in the first direction D1; specifically, the power plug 5 is disposed on the back side 15, and the power plug 5 includes a live wire plug 51 and a neutral wire plug 52.

[0048] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6 The AC conductive plate 6 is disposed on the conductive plate holder 2 and is directly or indirectly electrically connected to the power plug 5. Specifically, the AC conductive plate 6 includes a live wire conductive plate 61, a neutral wire conductive plate 62, and a ground wire conductive plate 63. The live wire conductive plate 61 is disposed in the live wire receiving area 21, the neutral wire conductive plate 62 is disposed in the neutral wire receiving area 22, and the ground wire conductive plate 63 is disposed in the ground wire receiving area 23. The live wire conductive plate 61 is directly connected to the live wire plug 51, and the neutral wire conductive plate 62 is directly connected to the neutral wire plug 52. The live wire conductive plate 61 includes a first live wire plug. The device includes a slot 611 and a second live wire slot 612. The first live wire socket 141 is positioned corresponding to the first live wire slot 611, and the second live wire socket 161 is positioned corresponding to the second live wire slot 612. The neutral wire conductive sheet 62 includes a first neutral wire slot 621 and a second neutral wire slot 622. The first neutral wire socket 142 is positioned corresponding to the first neutral wire slot 621, and the second neutral wire socket 162 is positioned corresponding to the second neutral wire slot 622. The grounding wire conductive sheet 63 has a grounding wire slot 631, and the grounding wire socket 143 is positioned corresponding to the grounding wire slot 631.

[0049] Please see Figure 1 and Figure 3 The switch 8 is disposed on the housing 1 and is electrically connected between the power plug 5 and the AC conductive plate 6. Specifically, in addition to directly connecting the power plug 5 to the AC conductive plate 6, the switch 8 can also be disposed between the power plug 5 and the AC conductive plate 6 to control the conduction or interruption of current. For example, the switch 8 can be connected to the live wire conductive plate 61 to control the conduction or interruption of the live wire current, or the switch 8 can be connected to the neutral wire conductive plate 62 to control the conduction or interruption of the neutral wire current.

[0050] The grounding screw 7 is located on the side 16 of the housing 1 and is electrically connected to the grounding wire conductive piece 63.

[0051] Please see Figure 3 , Figure 7 and Figure 8When using this counterweight adapter socket structure, since the first receiving area 111 and the second receiving area 112 of the housing 1 are located on opposite sides of the power plug 5 along the first direction D1, and the first direction D1 is parallel to the horizontal direction, the weight generated by the first circuit board 3 located in the first receiving area 111 and the weight generated by the second circuit board 4 located in the second receiving area 112 can be appropriately distributed on opposite sides of the power plug 5, without being excessively concentrated on the same side of the power plug 5. When the counterweight adapter socket structure is installed on a wall socket 9 through the power plug 5, the appropriate counterweight can prevent the counterweight adapter socket structure from tilting or swaying excessively with the power plug 5 as the fulcrum. Furthermore, when an external power cord is connected to the AC socket area 12 and the DC socket area 13, the power cord itself has weight and will generate torque with the power pin 5 as the fulcrum, which will affect the structure of the counterweight adapter. However, since the AC socket area 12 is located between the first receiving area 111 and the second receiving area 112 and is directly opposite the position of the power pin 5, the distance between the AC socket area 12 and the power pin 5 can be shortened, so that the torque generated by the weight of the power cord is minimized, and the tilting and swaying caused by the weight of the power cord to the structure of the counterweight adapter can be reduced.

[0052] Please see Figure 9 and Figure 10 In another embodiment, two DC power socket areas 13A are respectively disposed on opposite sides of an AC power socket area 12A. The aforementioned DC power socket area 13A is provided with a plurality of DC power output ports 41A, such as providing a 15W USB Type-A connector and a 20W USB Type-C connector. Compared with the above embodiment that can output a larger power wattage, the above embodiment requires the electronic components to be distributed on opposite sides of the AC power socket area 12A to avoid excessive weight concentration on the same side. However, in this embodiment, because the power wattage provided is lower, the required electronic components are lighter and occupy a smaller volume, so they can be disposed on the same side. Furthermore, in order to distribute the weight evenly on the counterweight adapter structure, the aforementioned DC power socket area 13A is provided on both opposite sides of the AC power socket area 12A. When an external power cord is connected, there will be no torque generated due to the power cord being concentrated on the same side, and no further tilting or swaying of the counterweight adapter structure.

[0053] Based on the above description of the embodiments, one can fully understand the operation, use, and effects of the present invention. The above embodiments are only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Simple equivalent changes and modifications made in accordance with the claims and description of the invention are all within the scope of the present invention.
