Description

Power adapter module

This invention relates to a power adapter module, particularly one that can extend the distance between a power adapter and a mains socket.

Since most mains outlets provide 110V or 220V power, many electronic devices or equipment require a power adapter to convert the power to lower voltage and current values when connected to the mains outlet. A power adapter typically has a pair of conductive blades and an output port. Each conductive blade plugs into the mains outlet to form an electrical connection, and the output port transmits the converted power to the electronic device or equipment via a transmission line for use.

However, because the power adapter plugs into the mains socket via conductive prongs and is often bulky, it can easily block the remaining sockets when installed. This can interfere with other plugs and render them unusable, wasting socket space. Furthermore, the power adapter is heavy, so when installed, it can easily come loose from the socket, compromising connection reliability.

In view of this, the author has focused on the shortcomings of the above-mentioned existing technologies and has conducted in-depth research and applied academic theories to try his best to solve the above-mentioned problems, which has become the goal of the author's improvement.

The main purpose of this invention is to extend the distance between the power adapter and the mains socket via the power cord, allowing the power adapter to be placed in the desired location. This not only prevents the power adapter from interfering with other plugs when plugged directly into the mains socket, but also prevents the power adapter from becoming loose from the mains socket due to its heavy weight, ensuring a reliable connection.

In order to achieve the above-mentioned purpose, this invention provides a power conversion module, including a power adapter, an adapter head and a power cord. The power adapter has a first connection part and at least one output port. The adapter head has a second connection part that is detachably connected to the first connection part. The power cord is connected to the adapter head.

In one embodiment of the present invention, the first connecting portion includes a hollow cylinder and a pair of conductive pins located in the hollow cylinder, and the second connecting portion includes a circular groove and a pair of arc grooves located in the circular groove.

In one embodiment of the present invention, the adapter includes a housing and a pair of conductive terminals, each conductive terminal is disposed in the housing and corresponds to each arc slot.

In one embodiment of the present invention, the hollow cylinder has a positioning block, and the second connecting portion has a positioning groove connected to the annular groove. The second connecting portion can rotate relative to the first connecting portion between an unlocked position and a locked position. When the second connecting portion is in the unlocked position, the positioning block is accommodated in the positioning groove. When the second connecting portion is in the locked position, the positioning block and the positioning groove are misaligned, and each conductive pin is located at one end of each arc groove and abuts each conductive terminal.

In one embodiment of the present invention, the first connecting portion includes a pair of conductive plugs, and the second connecting portion has a pair of slots, and each conductive plug is detachably plugged into each slot.

In one embodiment of the present invention, the power adapter includes a housing having a pair of positioning and receiving slots. Each conductive plug is pivotally connected to the housing and can be received in each positioning and receiving slot or protrude from each positioning and receiving slot.

In one embodiment of the present invention, the second connecting portion has a pair of positioning inserts, each positioning insert is respectively configured to correspond to each slot, and each positioning insert is detachably inserted into each positioning receiving slot.

In one embodiment of the present invention, the power cord includes a plug, a third connecting portion, and a wire, and the wire is connected between the plug and the third connecting portion.

In one embodiment of the present invention, the third connecting portion is a male connector, the adapter has a female connector, and the male connector is detachably connected to the female connector.

The detailed description and technical content of this work are illustrated below with accompanying diagrams. However, the attached diagrams are for illustrative purposes only and are not intended to limit this work.

This invention provides a power adapter module that connects to a mains power outlet (not shown) and converts electrical power into a specific voltage, current, and frequency for use by at least one electronic device (not shown). Referring to Figures 1, 2, and 7, a first embodiment of this power adapter module is shown, comprising a power adapter 10, a power adapter 20, and a power cord 30.

The power adapter 10 includes a housing 11 and has a first connection portion 12 and at least one output port 13. In this embodiment, the first connection portion 12 and the output port 13 are disposed on opposite sides of the housing 11, but the present invention is not limited thereto. Furthermore, in this embodiment, there are two output ports 13, each of which is a USB Type-C port. However, the present invention is not limited thereto. For example, the number of output ports 13 may be one or more than three, and the output ports 13 may be any of a USB Type-A port, a USB Type-B port, a Micro-USB port, a Mini-USB port, a Lightning port, an HDMI port, a D-sub port, a DVI port, or a DisplayPort port. A person skilled in the art should be able to make corresponding adjustments based on different needs.

The adapter 20 includes a housing 21 and a second connecting portion 22. The housing 21 is hollow and defines a cavity (not numbered). The second connecting portion 22 of the adapter 20 is removably connected to the first connecting portion 12 of the power adapter 10. The detailed structures of the second connecting portion 22 and the first connecting portion 12 will be described later and are not detailed here.

The power cord 30 is connected to the adapter 20. Specifically, the power cord 30 includes a plug 31, a wire 32 and a third connecting portion 33. The wire 32 is connected between the plug 31 and the third connecting portion 33. In this embodiment, the third connecting portion 33 is a male connector, and the adapter 20 has a female connector 23. The male connector of the third connecting portion 33 is detachably connected to the female connector 23 to connect the power cord 30 to the adapter 20, but the present invention is not limited to this. For example, the third connecting portion 33 can also be a female connector, and the adapter 20 has a male connector. The plug 31 is used to plug into the AC socket, that is, the power cord 30 can transmit power from the AC socket to the adapter 20 and the power adapter 10. In this way, the power cord 30 can be used to extend the distance between the power adapter 10 and the mains socket so that the power adapter 10 can be placed in a desired location. This not only prevents the power adapter 10 from interfering with other plugs when directly plugged into the mains socket, but also prevents the power adapter 10 from becoming loose from the mains socket due to its heavy weight, thereby ensuring a reliable connection.

To further explain, in this embodiment, the first connecting portion 12 includes a hollow cylindrical body 121 and a pair of conductive pins 122 located within the hollow cylindrical body 121. The second connecting portion 22 includes an annular groove 221 and a pair of arcuate grooves 222 located within the annular groove 221. Specifically, the hollow cylindrical body 121 is a hollow cylinder, and the conductive pins 122 are symmetrically arranged within the hollow cylindrical body 121. The annular groove 221 is an annular through-slot that passes through the housing 21 of the adapter 20 and communicates with the internal cavity of the housing 21. The arcuate grooves 222 are symmetrically arranged concentrically within the annular groove 221 and pass through the housing 21 of the adapter 20 to communicate with the internal cavity of the housing 21. The hollow cylinder 121 is removably inserted into the annular groove 221 along a plugging direction, and each conductive pin 122 is removably inserted into each arcuate groove 222 along the plugging direction. Thus, the first connecting portion 12 can be positioned on the second connecting portion 22 by inserting the hollow cylinder 121 into the annular groove 221, allowing each conductive pin 122 to be precisely inserted into the corresponding arcuate groove 222.

The adapter 20 also includes a pair of conductive terminals 24. Each conductive terminal 24 is located within the housing 21 of the adapter 20 and corresponds to a respective arcuate slot 222. Each conductive terminal 24 is electrically connected to the female connector 23 of the adapter 20. Therefore, when each conductive pin 122 is inserted into the corresponding arcuate slot 222 and forms an electrical connection with the conductive terminal 24, the adapter 20 is able to transfer power transmitted from the power cord 30 to the power adapter 10.

To further illustrate, the hollow cylinder 121 has at least one positioning block 123, and the second connecting portion 22 has at least one positioning groove 223 connected to the annular groove 221. The second connecting portion 22 can rotate between an unlocked position P1 and a locked position P2 relative to the first connecting portion 12. Specifically, please refer to Figures 3 and 4. When the second connecting portion 22 is in the unlocked position P1, the positioning block 123 of the first connecting portion 12 is accommodated in the positioning groove 223 of the second connecting portion 22. Therefore, the user can detach the second connecting portion 22 from the first connecting portion 12 in the direction opposite to the plug-in direction, thereby separating the power adapter 10 and the adapter 20. At this time, the conductive pins 122 and the conductive terminals 24 are misaligned with each other and no electrical connection is formed. 5 and 6 , when the second connecting portion 22 is rotated to the locked position P2, the positioning block 123 is misaligned with the positioning slot 223, so that each conductive pin 122 is located at one end of each arc-shaped slot 222 and abuts against each conductive terminal 24. This allows each conductive pin 122 to form an electrical connection with each conductive terminal 24. At this point, the power adapter 10 and the adapter 20 are locked and cannot be separated in the direction opposite to the insertion direction.

It should be noted that, for ease of assembly and symmetry, the number of positioning blocks 123 and the number of positioning grooves 223 are both two. Each positioning block 123 is symmetrically arranged on the outer edge of the hollow cylinder 121, and each positioning groove 223 is also symmetrically arranged on the outer edge of the annular groove 221. The structure and position of each conductive terminal 24 are also symmetrically arranged. Thus, the hollow cylinder 121 and the positioning blocks 123 are first inserted into the annular groove 221 and the positioning grooves 223 along the insertion direction. Then, the second connecting portion 22 can be rotated to the locking position P2 regardless of whether it is rotated forward or reverse. This allows each conductive pin 122 to be positioned at one end of each arc-shaped groove 222 and form an electrical connection with each conductive terminal 24, thereby improving the convenience during assembly.

Please refer to Figures 8 to 10, which are the second embodiment of the power adapter module of this invention. The main difference between the second embodiment and the first embodiment lies in the detailed structure and assembly method of the first connecting portion 12 and the second connecting portion 22, which are described in detail below.

In this embodiment, the first connecting portion 12 includes a pair of conductive plugs 124 extending in parallel, and the second connecting portion 22 has a pair of slots 224 arranged in parallel. Each conductive plug 124 is detachably plugged into each slot 224, thereby forming an electrical connection with each conductive terminal 24 in the adapter 20. In other words, the first connecting portion 12 in this embodiment is in the form of a general plug, and the second connecting portion 22 is in the form of a jack of a general socket. Therefore, when the power conversion module of this invention does not need to rely on the power cord 30 for extension under certain circumstances, and there is something under the AC socket that can be supported, the power adapter 10 in this embodiment can be directly plugged into the AC socket through the conductive plugs 124 of the first connecting portion 12, thereby increasing the diversity of use.

In this embodiment, the outer housing 11 of the power adapter 10 has a pair of positioning and receiving slots 111. Each positioning and receiving slot 111 is elongated. One end of each conductive plug 124 is pivoted into one end of each positioning and receiving slot 111 of the outer housing 11, allowing each conductive plug 124 to be received within or protrude from each positioning and receiving slot 111. Specifically, when each conductive plug 124 is pivoted relative to the outer housing 11 until it is parallel to each positioning and receiving slot 111, each conductive plug 124 is completely received within each positioning and receiving slot 111. When the conductive tabs 124 are pivoted relative to the housing 11 to be perpendicular to the positioning slots 111, they protrude from the positioning slots 111 and can be plugged into the slots 224 of the adapter 20. Thus, when the power adapter 10 is separated from the adapter 20, the conductive tabs 124 are stored in the positioning slots 111 for protection, preventing them from being damaged by impact.

To further explain, the second connecting portion 22 in this embodiment also has a pair of positioning inserts 225. Each positioning insert 225 is configured to correspond to each slot 224. Specifically, each positioning insert 225 is parallel to the corresponding slot 224 and is arranged on the same straight line as the corresponding slot 224. Each positioning insert 225 is detachably plugged into each positioning receiving slot 111. Thereby, when each conductive insert 124 of the first connecting portion 12 is plugged into each slot 224 of the second connecting portion 22, each positioning insert 225 of the second connecting portion 22 can be simultaneously plugged into each positioning receiving slot 111 of the first connecting portion 12, thereby improving the positioning effect and connection stability between the two.

The power adapter module of this invention is detachably connected to the first connection portion 12 of the power adapter 10 via the second connection portion 22 of the adapter head 20. With the power cord 30 connected to the adapter head 20, the power cord 30 can be used to extend the distance between the power adapter 10 and the mains outlet, allowing the power adapter 10 to be placed in a desired location. This not only prevents the power adapter 10 from interfering with other plugs when directly plugged into the mains outlet, but also prevents the power adapter 10 from becoming loose from the mains outlet due to its heavy weight, thereby ensuring a reliable connection.

In summary, the aforementioned disclosure of this invention is intended to enable those skilled in the art to clearly understand the technical content of this invention and implement it accordingly. It is not intended to limit the scope of patent protection for this invention. Furthermore, this invention is of course capable of numerous other embodiments not listed here. Without departing from the spirit and substance of this invention, those skilled in the art should be able to develop various corresponding modifications and variations based on this invention. Such modifications and variations should fall within the scope of protection of the patents applied for this invention.
