Background Art

[0002] As people's living standards gradually improve, the opportunities for overseas travel or business trips are increasing.

Embodiments for Carrying out the Invention

[0019] To facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to examples and drawings. However, the content referred to in the embodiments does not limit the present invention. The present invention will be described in detail below with reference to the drawings.

[0020] Example 1 According to an embodiment of the present invention, a holder structure for a power adapter is provided that has multiple sets of sockets and a compact structure. As an important component of the power adapter, the holder structure of the present invention can provide main sockets 111 and first sub-sockets 121 provided on two adjacent sides. In this embodiment, the multiple sets of main sockets 111 are arranged in parallel along one direction. Each of the multiple sets of main sockets 111 is of a standard. Specifically, the main sockets 111 are provided as 2-pin sockets and 3-pin sockets of at least one specification. The first sub-sockets 121 are provided on the sides extending along the parallel direction of the main sockets 111. This allows the holder structure of the present invention to provide more insertion positions, and can accommodate the insertion of more electrical products when using electrical products.

[0021] In this embodiment, as shown in Figure 1-7, an embodiment of the present invention provides a holder structure for a power adapter that has multiple sets of sockets and a compact structure. The holder structure for a power adapter that has multiple sets of sockets and a compact structure includes a holder 200. The holder 200 is provided with multiple main sockets 111 and first sub-sockets 121 of different standards. The main sockets 111 and 121 are provided on two adjacent sides. The first sub-sockets 121 are located on the parallel extension of the multiple main sockets 111. A pin assembly 300 is further slidably contacted to the holder 200. The pin assembly 300 reciprocates in a direction perpendicular to the position of the main sockets. The pin assembly 300 includes multiple pin units 310 arranged side by side along the parallel direction of the main sockets 111. Each pin unit 310 includes a first telescopic member 311. The first expandable member 311 is provided with a terminal 313 for insertion into an external outlet. The orthographic projection of the first sub-insertion hole 121 facing the pin assembly 300 is located on one of the outer insertion units 310. The insertion unit 310 corresponding to the first sub-insertion hole 121 further includes a second expandable member 320 that is slidably mounted on the holder 200. The length of the terminal 313 on the insertion unit 310 corresponding to the first sub-insertion hole 121 protruding from the holder 200 is longer than the length of the terminal 313 on the other insertion unit 310 protruding from the holder 200.

[0022] In this embodiment, the pin unit 310 can protrude from the holder 200 or retract into the holder 200 by sliding on the holder 200. After the pin unit 310 protrudes from the holder 200, it is used to be inserted into an external socket. In this case, it may be inserted through the main insertion hole 111 or the first sub-insertion hole 121. Thereby, more insertion positions are provided, and the usage performance of the socket is improved.

[0023] In this embodiment, the holder 200 is further provided with a first conductive fitting 210 corresponding to the main insertion hole 111 and the first sub-insertion hole 121. There are two first conductive fittings 210. The two first conductive fittings 210 are parallel to each other and respectively correspond to the live wire and the neutral wire. Each first conductive fitting 210 is provided to extend along a predetermined direction, and a plurality of main insertion positions 211 corresponding to the main insertion hole 121 are arranged in parallel along the predetermined direction thereon. At the end of the first conductive fitting 210, a first sub-insertion position 212 corresponding to the first sub-insertion hole 121 is provided. The opening of the first sub-insertion position 212 faces the extending direction of the predetermined direction.

[0024] In this embodiment, the two first conductive fittings 210 are mirror-symmetrical to each other and respectively correspond to the live wire and the neutral wire. Thereby, when an electrical product is inserted into the first conductive fitting 210, it is connected to the neutral wire and the live wire to form a circuit. The two first conductive fittings 210 are provided to extend along one predetermined direction. The first sub-insertion position 212 is formed at the end position of the first conductive fitting 210. Thereby, the first sub-insertion position 212 is located on the extension line where the main insertion positions 211 are arranged in parallel along the predetermined direction.

[0025] More specifically, the first conductive fitting 210 includes a single body 213. The main insertion position 211 is formed on the body 213. A first projection 214 is formed on the end of the body 213 that extends along a predetermined direction, projecting upward and extending along the predetermined direction. The first secondary insertion position 212 is formed on the first projection 214. The insertion opening of the first secondary insertion position 212 is open in the direction extending along the predetermined direction.

[0026] In this embodiment, the first conductive fitting 210 includes a single body 213. The main insertion position 211 is formed on the body 213. A first projection 214 is formed on one end of the body 213 that extends along a predetermined direction, projecting upward and extending along the predetermined direction. The first secondary insertion position 212 is formed on the first projection 214. The insertion opening of the first secondary insertion position 212 is open in the direction extending along the predetermined direction. As shown in Figure 4, the first conductive fitting 210 is provided as an elongated structure. The main insertion position 211 and the first secondary insertion position 212 are arranged along the length of the first conductive fitting 210, thereby allowing the first secondary insertion position 212 to be located at the end of the first conductive fitting 210. In the production process of the first conductive fitting 210, the copper material can be pressed and bent to complete the processing, making the processing simple and resulting in high strength and conductivity for the first conductive fitting 210. In contrast, if the orientation of the first sub-insertion position 212 is not aligned with the extension of the arrangement of the main insertion position 211, it is necessary to bend and stretch a portion of each of the two first conductive fittings 210 to one side. Of these, the formed portion of one of the first conductive fittings 210 needs to be longer. Only by further bending the portion that is bent and stretched to one side upwards or downwards can the insertion position on one side be formed. In this case, planes of different heights are formed between this portion and the body of the conductive fitting, making the structure more complex. As the height of the conductive fitting increases and the stretched portion increases, it becomes necessary to add reinforcing welding points to the conductive fitting, which reduces the strength of the conductive fitting.

[0027] In this embodiment, the holder 200 is further provided with a second conductive fitting 220 corresponding to the first conductive fitting 210. There are two second conductive fittings 220, one corresponding to the neutral wire and the other to the live wire. A conductive material 204 is provided between the first conductive fitting 210 and the second conductive fitting 220. The pin unit 310 slides along the holder 200 toward the second conductive fitting 220, thereby inserting the first expandable member 311 into the second conductive fitting 220, and electrically connecting the first conductive fitting 210 to the terminal 313.

[0028] A second conductive fitting 220 is provided, and the pin unit 310 slides on the holder 200 to protrude the terminal 313 to the outside, after which it can be plugged into an external outlet, thereby charging the terminal 313. In this case, the first expandable member 311 is plugged into the second conductive fitting 220, so that the terminal 313 is electrically connected to the second conductive fitting 220, charging the second conductive fitting 220, and the conductive material 204 charges the first conductive fitting 210. As a result, the electrical product can be plugged into the main socket 111 or the first sub-socket 121 and use electricity.

[0029] In this embodiment, the pin unit 310 corresponding to the first sub-insertion position 212 is a European standard pin unit 310a. An internal fitting structure is further provided between the first expandable member 311 and the second expandable member 320 of the European standard pin unit 310a. As a result, when the European standard pin unit is pulled into the holder 200, at least a portion of the first expandable member 311 is fitted into the second expandable member 320.

[0030] In this embodiment, the European standard pin unit 310a is positioned at the first sub-insertion position 212 (first sub-insertion hole 121). Due to the internal fitting structure, when the first telescopic member 311 and the second telescopic member 320 are retracted into the holder 200, at least a portion of the first telescopic member 311 can be fitted into the second telescopic member 320, reducing the overall height of the European standard pin unit 310a, ensuring a compact structure for the holder, ensuring a compact structure for the conversion outlet, and resulting in a small volume.

[0031] Specifically, the fitting structure includes a fitting portion 316 formed on the first expandable member 311 and projecting toward the second expandable member 320, and a pushing portion 317 extending toward both ends along the length of the first expandable member 311. The terminal 313 is formed on the fitting portion 316. A locking portion 318 is provided on the side surface of the first expandable member 311. There is a step between the locking portion 318 and the pushing portion 314 on the surface facing the second expandable member 320. The fitting structure further includes a base 321 formed on one end of the second expandable member 320, and a side wall 323 formed on one edge of the base 321 and extending toward the direction away from the base 321. A cavity 322 is formed at the end of the base 321 facing the first expandable member 311. The cavity 322 is used for inserting the fitting portion 316. A through hole is provided at the bottom of the cavity 322 for the terminal 313 to extend. An interlocking groove 324 is formed in the side wall 323 for the locking portion 318 to slide. The sliding of the locking portion 318 is restricted to the interior of the interlocking groove 324.

[0032] By providing the first expandable member 311 of the European standard pin unit 310a as an insertion portion 316 and a push portion 317, when the terminal 313 is fixed to the insertion portion 316, the insertion portion 316 has sufficient volume to ensure the mounting requirements of the terminal 313 and mutual insulation. In the process of pushing out the European standard pin unit 310a, the insertion portion 316 enters the cavity 322 of the second expandable member 320, and the push portion 317 contacts the end of the base 321 of the second expandable member 320, thereby pushing out the second expandable member 320. When the European standard pin unit 310a is retracted into the mounting space 101, pulling the moving end 312 causes the locking portion 318 to slide within the interlocking groove 324, and after being restricted by the top of the sliding groove 325, retracts the second expandable member 320 into the mounting space 101. The above structure ensures that when a European standard socket unit is routed into the mounting space 101, the structure becomes more compact and the height of the outlet does not increase.

[0033] To facilitate the reciprocating sliding of the pin unit 310 along the holder 200, a movable end 312 protruding from the holder 200 is formed at any longitudinal end of the first expandable member 311, and the first expandable member 311 is further provided with an insertion device 314, one end of which is connected to a terminal 313 and the other end of which is inserted into a second conductive fitting 220. In this embodiment, the movable end 312 extends outside the holder 200. This allows the terminal 313 to be advanced through the first expandable member 311 by operating the movable end 312. The first expandable member 311 is also provided with an insertion device 314. When the pin unit 310 moves outward along the holder 200, after the terminal 313 exits the holder 200, the first expandable member 311 is inserted into the second conductive fitting 220 via the insertion device 314, thereby establishing an electrical connection between the terminal 313 and the second conductive fitting 220. Furthermore, when the terminal 313 is inserted into an external outlet, the first conductive fitting 210 becomes charged by the second conductive fitting 220 and the conductive material 204.

[0034] In this embodiment, the holder 200 includes an upper frame 201 and a lower frame 202 provided along its vertical direction. A plurality of support guide columns 203 are provided between the upper frame 201 and the lower frame 202. The first conductive fitting 210 and the second conductive fitting 220 engage with the upper frame 201 and the lower frame 202, respectively. A conductive material 201 for electrical connection is provided between the first conductive fitting 210 and the second conductive fitting 220. The first telescopic member slides against the guide columns 203. In this embodiment, the upper frame 201 has a mounting groove 2011 provided according to a predetermined shape. The first conductive fitting engages within the mounting groove 2011. Similarly, the lower frame 202 has a mounting groove (not shown) which facilitates the attachment of the second conductive fitting.

[0035] There are two conductive members 204, each connected at both ends to a first conductive fitting 210 and a second conductive fitting 220, respectively, and used to provide electrical conductivity between the corresponding parallel first conductive fitting 210 and second conductive fitting 220. One conductive member 204 is made up of a guide column 203, and the other conductive member 204 is made up of a fuse tube.

[0036] Specifically, one guide post 203 is made of metal, and both ends are connected to a first conductive fitting 210 and a second conductive fitting 220, which correspond to the neutral wire, thereby electrically connecting the first conductive fitting 210 and the second conductive fitting 220. In this case, the first expansion member 311 slides against the guide post 203. Since both ends of the conductive material, which is made of a fuse tube, are provided on the first conductive fitting 210 and the second conductive fitting 220, which correspond to the live wire, a fuse structure is provided. This ensures electrical safety by cutting the fuse tube in the event of overvoltage, overcurrent, etc.

[0037] Example 2 The technical means provided in this embodiment are almost the same as those in Embodiment 1 described above. In this embodiment, a second sub-insertion hole 131 is provided for insertion in order to improve the performance of the outlet. Specifically, as shown in Figure 1-5, the holder 200 is further provided with a second sub-insertion hole 131. The second sub-insertion hole 131 is provided on the side of the holder 200 facing away from the first sub-insertion hole 121. The second sub-insertion hole 131 is provided at the other end of the extension line in the direction in which the multiple main insertion holes 111 are arranged in parallel, corresponding to the first sub-insertion hole 121. The first sub-insertion hole 121 and the second sub-insertion hole 131 are of the same or different specifications. The body 213 has a second projection 215 formed at the other end extending along the predetermined direction, which projects upward and also extends along the predetermined direction. A second secondary insertion position 216 corresponding to the second secondary insertion hole 131 is formed on the second projection 215.

[0038] In other words, a second sub-insertion hole 131 is provided on the side of the holder 200 opposite to the side of the holder 200 where the first sub-insertion hole 121 is provided. This makes it possible to insert the three plugs into the main insertion hole 111, the first sub-insertion hole 121, and the second sub-insertion hole 131, respectively, providing more insertion positions and satisfying the user's electrical usage needs. Furthermore, when providing a second sub-insertion position 216 corresponding to the second sub-insertion hole 131, a second projection 215 is provided on another extended end of the main body 213. The second sub-insertion position 216 is provided on the second projection 215. As a result, the first auxiliary insertion position 212, the main insertion position 211, and the second auxiliary insertion position 216 are provided along the same predetermined direction, and the first conductive fitting 210 can be integrally molded by press working or the like from the same copper material, thereby guaranteeing the reliability and safety of the first conductive fitting 210.

[0039] Example 3 The technical means provided in this embodiment are almost identical to those in Embodiment 1 described above. In this embodiment, a third sub-insertion hole 141 is further provided for insertion based on Embodiment 1 in order to improve the performance of the outlet. In this embodiment, the holder 200 is further provided with the third sub-insertion hole 141. The third sub-insertion hole 141 is provided on the surface adjacent to the first sub-insertion hole 121 and is located lateral to the main insertion hole 111. The third sub-insertion hole 141 and the first sub-insertion hole 121 are of the same or different specifications. One of the main bodies 213 has an extended portion 218 molded toward the side perpendicular to the predetermined direction, and the other main body 213 has a connecting beam 219 molded parallel to the extended portion 218. The main body 213 of the extended portion 218 straddles the connecting beam lateral 219 and extends to the side of the main body 213 on which the extended portion is provided. A third secondary insertion position 217 corresponding to the third secondary insertion hole 141 is formed at the free end of the extended portion 218 and the connecting beam 219.

[0040] In other words, in this embodiment, the provision of the main insertion hole 111, the first sub-insertion hole 121, and the third sub-insertion hole 141 improves the usability of the outlet and provides the user with more insertion positions. In this embodiment, by providing the third insertion hole on the surface facing the movable end of the pin unit, the number of insertion positions can be increased without interfering with the operation of the movable end.

[0041] Example 4 In this embodiment, a third sub-insertion hole 141 is provided based on the technical means of Embodiment 2 in order to further improve the usability of the outlet.
