[0056] The detailed description and technical content of the present application will be described below with reference to the accompanying drawings, however, the accompanying drawings are only used for illustration purposes and are not used to limit the present application.

[0057] The present application provides a power adapter module for connecting to a power outlet (not shown) and converting power to a specific voltage, current and frequency for use by at least one electronic device (not shown). Please refer to Figure 1 , Figure 2 and Figure 7 for a first embodiment of the power adapter module of the present application, which includes a power adapter 10, an adapter head 20 and a power cord 30.

[0058] The power adapter 10 comprises a housing 11, and the power adapter 10 has a first connecting portion 12 and at least one output port 13. In the embodiment, the first connecting portion 12 and the output port 13 are respectively arranged on opposite sides of the housing 11, but the utility model is not limited thereto. In addition, the number of the output port 13 in the embodiment is two, and each output port 13 is a USB Type-C interface, but the utility model is not limited thereto. For example, the number of the output port 13 can be only one or more than three, and the output port 13 can be any one of a USB Type-A interface, a USB Type-B interface, a Micro-USB interface, a Mini-USB interface, a Lightning interface, an HDMI interface, a D-sub interface, a DVI interface or a Display port interface, and those skilled in the art should be able to make corresponding adjustments according to different needs.

[0059] The adapter 20 comprises a housing 21, and the adapter 20 has a second connecting portion 22. The inside of the housing 21 is hollow and has a cavity (not labeled in the figure). The second connecting portion 22 of the adapter 20 is detachably connected to the first connecting portion 12 of the power adapter 10. The detailed specific structure of the second connecting portion 22 and the first connecting portion 12 will be described later, and will not be described here.

[0060] The power cord 30 is connected to the adapter 20. Specifically, the power cord 30 comprises 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 the embodiment, the third connecting portion 33 is a male connector, and the adapter 20 has a female connector 23, and 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 utility model is not limited thereto. 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 for plugging into the power socket, that is, the power cord 30 can transmit the power of the power socket to the adapter 20 and the power adapter 10. In this way, the distance between the power adapter 10 and the power socket can be extended by the power cord 30 to place the power adapter 10 at the desired position, which can not only avoid the situation that the power adapter 10 is easily interfered with other plugs when directly plugged into the power socket, but also avoid the power adapter 10 from being easily loosened from the power socket due to its heavy weight to ensure the connection reliability.

[0061] Further explanation, in the present embodiment, the first connecting portion 12 comprises a hollow cylinder 121 and a pair of conductive pins 122 located in the hollow cylinder 121, and the second connecting portion 22 comprises a circular groove 221 and a pair of arc grooves 222 located in the circular groove 221. Specifically, the hollow cylinder 121 is a hollow cylinder, and the conductive pins 122 are symmetrically arranged in the hollow cylinder 121. The circular groove 221 is a circular groove that penetrates the shell 21 of the adapter 20 and communicates with the cavity inside the shell 21, and the arc grooves 222 are symmetrically arranged around the circular groove 221 and penetrate the shell 21 of the adapter 20 and communicate with the cavity inside the shell 21. The hollow cylinder 121 is detachably inserted into the circular groove 221 along an insertion direction, and the conductive pins 122 are detachably inserted into the arc grooves 222 along the insertion direction. In this way, the first connecting portion 12 can be positioned in the second connecting portion 22 by inserting the hollow cylinder 121 into the circular groove 221, so that the conductive pins 122 can be precisely inserted into the corresponding arc grooves 222.

[0062] In addition, the adapter 20 further comprises a pair of conductive terminals 24. Each conductive terminal 24 is arranged in the shell 21 of the adapter 20, and each conductive terminal 24 corresponds to each arc groove 222. Each conductive terminal 24 is electrically connected to the connector female head 23 of the adapter 20. In this way, when the conductive pins 122 are inserted into the corresponding arc grooves 222 and form an electrical connection with the conductive terminals 24, the adapter 20 can transfer the power transmitted by the power cord 30 to the power adapter 10.

[0063] Further explanation, the hollow cylinder 121 has at least one positioning block 123, and the second connecting portion 22 has at least one positioning groove 223 that communicates with the circular groove 221. The second connecting portion 22 can be rotated relative to the first connecting portion 12 between an unlocked position P1 and a locked position P2. Specifically, as shown in Figure 3 and Figure 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, so that the user can separate the second connecting portion 22 from the first connecting portion 12 along the opposite direction of the insertion direction, thereby separating the power adapter 10 from the adapter 20, and at this time, the conductive pins 122 and the conductive terminals 24 are misaligned and do not form an electrical connection. Please continue to refer to Figure 5 and Figure 6As shown, when the second connecting portion 22 is rotated to the locking position P2, the positioning blocks 123 are misaligned with the positioning grooves 223, so that each conductive pin 122 is located at one end of the arc-shaped groove 222 and abuts against the conductive terminal 24, thereby forming an electrical connection between the conductive pin 122 and the conductive terminal 24, and the power adapter 10 and the adapter 20 are locked and cannot be separated in the opposite direction of the insertion direction.

[0064] It should be noted that, for the convenience of assembly and symmetry, the number of the positioning blocks 123 and the number of the positioning grooves 223 are both two, each positioning block 123 is symmetrically arranged at the outer edge of the hollow cylinder 121, each positioning groove 223 is symmetrically arranged at the outer edge of the annular groove 221, and the structure and position of each conductive terminal 24 are also symmetrically arranged. Therefore, as long as the hollow cylinder 121 and the positioning blocks 123 are inserted into the annular groove 221 and the positioning grooves 223 in the insertion direction, the second connecting portion 22 can be rotated to the locking position P2 regardless of the clockwise or counterclockwise rotation, so that each conductive pin 122 can be positioned at one end of the arc-shaped groove 222 and form an electrical connection with the conductive terminal 24, thereby improving the convenience of assembly.

[0065] Please continue to refer to Figure 8 to Figure 10 As shown, the second embodiment of the power adapter module of the utility model, and the main difference between the first embodiment is that the first connecting portion 12 and the second connecting portion 22 detailed structure and assembly mode, specific description as follows.

[0066] In this embodiment, the first connecting portion 12 includes a pair of conductive tabs 124 extending in parallel, and the second connecting portion 22 has a pair of insertion slots 224 arranged in parallel. Each conductive tab 124 is detachably inserted into each insertion 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 general socket. Therefore, when the power adapter module of the utility model does not need to rely on the power cord 30 for extension under certain circumstances, and there is an object under the power socket to support, the power adapter 10 in this embodiment can be directly inserted into the power socket through the conductive tabs 124 of the first connecting portion 12, thereby increasing the versatility of use.

[0067] In the embodiment, the housing 11 of the power adapter 10 has a pair of positioning receiving grooves 111. Each positioning receiving groove 111 is in a strip shape. One end of each conductive tab 124 is pivotally connected to one end of each positioning receiving groove 111 of the housing 11, so that each conductive tab 124 can be received in or protrude out of each positioning receiving groove 111. Specifically, when each conductive tab 124 is pivoted relative to the housing 11 to be parallel to each positioning receiving groove 111, each conductive tab 124 is completely received in each positioning receiving groove 111. When each conductive tab 124 is pivoted relative to the housing 11 to be perpendicular to each positioning receiving groove 111, each conductive tab 124 protrudes out of each positioning receiving groove 111 and can be inserted into each slot 224 of the adapter 20. In this way, when the power adapter 10 is separated from the adapter 20, each conductive tab 124 is received in each positioning receiving groove 111 for protection, so as to avoid damage of each conductive tab 124 due to impact.

[0068] Further, the second connecting portion 22 of the embodiment further has a pair of positioning tabs 225. Each positioning tab 225 corresponds to each slot 224. Specifically, each positioning tab 225 is parallel to and arranged on the same line as the corresponding slot 224. Each positioning tab 225 is detachably inserted into each positioning receiving groove 111. In this way, when each conductive tab 124 of the first connecting portion 12 is inserted into each slot 224 of the second connecting portion 22, each positioning tab 225 of the second connecting portion 22 can be simultaneously inserted into each positioning receiving groove 111 of the first connecting portion 12, so as to improve the positioning effect and connection stability between the two.

[0069] The power adapter connection module can detachably connect the second connecting portion 22 of the adapter 20 to the first connecting portion 12 of the power adapter 10 through the second connecting portion 22 of the adapter 20, and the power cord 30 is connected to the adapter 20. Therefore, the distance between the power adapter 10 and the power socket can be extended by the power cord 30 to place the power adapter 10 at a desired position. This can not only avoid the situation that the power adapter 10 is easily interfered with other plugs when directly inserted into the power socket, but also avoid the power adapter 10 from being easily loosened from the power socket due to the heavy weight of the power adapter 10 to ensure the connection reliability.

[0070] To sum up, the foregoing disclosed content of the utility model is for letting the person with ordinary knowledge in the art can clearly understand the technical content of the utility model and implement accordingly, and is not intended to limit the patent protection scope of the utility model. In addition, the utility model can of course have other unlisted various embodiments, and the person skilled in the art should evolve various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but these corresponding changes and deformations should all belong to the protection scope of the patent applied for by the utility model.
