[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] As Figure 1 shown, generally multiple socket holders 2 and corresponding live wire electrical connection pieces 3 and neutral wire electrical connection pieces 4 are installed in the power adapter. Currently, the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 pass through the middle area of the socket holder 2 and are installed in a stacked manner up and down, and due to safety performance requirements, a sufficient distance needs to be ensured between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4. Such a socket holder 2 has a large volume, which ultimately leads to a large overall volume of the power adapter.

[0034] As Figures 2 to 4 shown, the embodiment of the present utility model provides a socket holder 2. At least two installation cavities 21 are provided on the socket holder 2. The installation cavities 21 are used to install the electrical connection parts 31 of the live wire electrical connection piece 3 or the neutral wire electrical connection piece 4. The socket holder 2 has a three-pole side 25 and a two-pole side 26, the three-pole side 25 and the two-pole side 26 are oppositely arranged, and installation channels 23 for installing the live wire electrical connection piece 3 or the neutral wire electrical connection piece 4 are provided on the three-pole side 25 and the two-pole side 26; the distance L1 between the installation channels 23 on the three-pole side 25 and the two-pole side 26 is less than the length L2 of the socket holder 2 in the direction from the three-pole side 25 to the two-pole side 26.

[0035] The socket base 2 of the present utility model can be applied to a power adapter. The live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 can be respectively arranged on opposite sides of the socket base 2, that is, on the installation channels 23 of the three-pole side 25 and the two-pole side 26, making full use of the original space on opposite sides of the socket base 2 to realize the installation of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4, without occupying a certain volume in the middle area of the socket base 2, making the overall structure of the power adapter compact, small in volume, and convenient for carrying and transportation. At the same time, since the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are on opposite sides of the socket base 2, the distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 is far enough, which can fully ensure that the distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 meets the safety performance requirements, and there is no need to consider the safety distance. Therefore, the technical solution of the present utility model can reduce the volume of the socket base 2, and ultimately make the overall volume of the power adapter smaller on the premise of ensuring safety performance requirements.

[0036] It should be noted that, as shown in Figure 4 The two-pole side 26 refers to the side of the socket base 2 where a two-pin plug is inserted, and the side opposite to the two-pole side 26 is the three-pole side 25.

[0037] Installation retaining pieces 22 are arranged on the three-pole side 25 and the two-pole side 26. The installation retaining pieces 22 and the outer wall surface of the installation cavity 21 form an installation channel 23. In this solution, by adding the installation retaining pieces 22 and using the outer wall surface of the original installation cavity 21 and the installation retaining pieces 22 to form the installation channel 23, the installation of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 is realized, and the structure of the installation channel 23 is simple. At the same time, the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 can be assembled by plugging and unplugging, and the assembly is simple. Specifically, one, two or three installation retaining pieces 22 can be provided.

[0038] Specifically, the distance between the installation channels 23 on the three-pole side 25 and the two-pole side 26 is 3 mm to 10 mm, ensuring a sufficient safety distance when the spacing is appropriate.

[0039] The present utility model also discloses a power adapter, as shown in Figures 2 to 4 The power adapter includes a housing 1, the socket base 2 as described above, a live wire electrical connection piece 3 and a neutral wire electrical connection piece 4; electrical connection parts 31 are arranged on the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4, and the socket base 2 is installed in the housing 1; the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are respectively installed in the installation channels 23 of the three-pole side 25 and the two-pole side 26, and the electrical connection parts 31 of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are installed in the installation cavity 21.

[0040] In the power adapter of the present utility model, the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are arranged on opposite sides of the socket base 2, making full use of the original space on the opposite sides of the socket base 2 to install the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4, without occupying a certain volume in the middle area of the socket base 2. At the same time, since the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are located on opposite sides of the socket base 2, the distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 is far enough to fully ensure that the distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 meets the safety performance requirements. Therefore, the technical solution of the present utility model can reduce the volume of the socket base 2, and ultimately make the overall volume of the power adapter smaller on the premise of ensuring the safety performance requirements.

[0041] Specifically, the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are made of conductive metal, such as copper sheets, etc. The electrical connection part 31 is the part used to connect the power adapter to an external power source or electrical equipment. When the user inserts the plug of the electrical equipment into the jack 111 on the power adapter, the electrical connection part 31 comes into contact with the metal pin on the plug to establish an electrical connection. The electrical connection part 31 on the live wire electrical connection piece 3 is usually connected to the live wire of the power source to transmit the current of the power source. The electrical connection part 31 on the neutral wire electrical connection piece 4 is connected to the neutral wire of the power source to form a loop, enabling the current to flow back to the power source. Installing the electrical connection part 31 in the corresponding installation cavity 21 can ensure the firm installation of the electrical connection part 31.

[0042] As Figure 4 shown, the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are installed vertically on one side and the other side of the socket base 2. Installing the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 vertically in the installation channel 23 makes full use of the original space of the socket base 2. Compared with horizontal installation or other installation methods, vertical installation can make more effective use of the space of the socket base 2 and reduce the volume of the power adapter. At the same time, when the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are in a vertical state, when the pin of the external electrical plug is inserted into the jack 111, it can withstand a greater force. In addition, in the vertical state, the contact area between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 and the installation position of the socket base 2 is larger, which can make it easier to firmly fix the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4.

[0043] As Figure 4 and Figure 5As shown, mounting stoppers 22 are provided on both sides of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4. The mounting stoppers 22 and the outer wall surface of the mounting cavity 21 form a mounting channel 23, and the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are installed in the mounting channel 23. In this solution, by adding the mounting stoppers 22 and using the outer wall surface of the original mounting cavity 21 and the mounting stoppers 22 to form the mounting channel 23, the installation of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 is realized, and the installation structure is simple. At the same time, the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 can be assembled by plugging and unplugging, and the assembly is simple. Specifically, one, two or three mounting stoppers 22 can be provided on one side of the socket base 2.

[0044] As Figure 4 shown, the mounting cavity 21 includes two live wire cavities 211 and two neutral wire cavities 212; the electrical connection part 31 of the live wire electrical connection piece 3 is introduced into one live wire cavity 211 and then led to the other live wire cavity 211, and the electrical connection part 31 of the neutral wire electrical connection piece 4 is introduced into one neutral wire cavity 212 and then led to the other neutral wire cavity 212. The electrical connection part 31 of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 is directly introduced from one cavity to another cavity, which can simplify the structure. Specifically, in the two live wire cavities 211, one live wire cavity 211 is the live wire connection port of the two-pin plug, and the other live wire cavity 211 is the live wire connection port of the three-pin plug. Similarly, in the two neutral wire cavities 212, one neutral wire cavity 212 is the neutral wire connection port of the two-pin plug, and the other live wire cavity 211 is the neutral wire connection port of the three-pin plug. That is, the power adapter of the present utility model can be plugged with both two-pin plugs and three-pin plugs.

[0045] Specifically, as Figure 4 shown, a plurality of socket bases 2 are provided, and the plurality of socket bases 2 are arranged in parallel and at intervals in sequence. The live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 extend along the arrangement direction of the plurality of socket bases 2; the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are respectively installed in the mounting channels 23 on the three-pole side 25 and the two-pole side 26 of each socket base 2. The power connection of each socket base 2 is realized through one live wire electrical connection piece 3 and one neutral wire electrical connection piece 4. More specifically, as Figure 6 shown, the plurality of socket bases 2 are divided into two groups. Each group of socket bases 2 includes a plurality of socket bases 2 arranged in parallel and at intervals in sequence. The two groups of socket bases 2 are arranged in parallel; the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 are respectively installed in the mounting channels 23 on the three-pole side 25 and the two-pole side 26 of each group of socket bases 2.

[0046] As Figure 4 and Figure 5As shown, the power adapter further includes a ground wire electrical connection piece 6. The ground wire electrical connection piece 6 is also provided with an electrical connection portion 31. A mounting cavity 21 is correspondingly provided on the socket base 2. The electrical connection portion 31 of the ground wire electrical connection piece 6 is also installed in the corresponding mounting cavity 21. The electrical connection portion 31 of the ground wire electrical connection piece 6 is used for plugging the ground wire pin of a three-pin plug. Specifically, the electrical connection portion 31 of the ground wire electrical connection piece 6 is located between the electrical connection portions 31 of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 for plugging the live wire pin and the neutral wire pin of a two-pin plug. The electrical connection portions 31 of the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 for plugging the live wire pin and the neutral wire pin of a three-pin plug are located below the electrical connection portion 31 of the ground wire electrical connection piece 6.

[0047] The distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 is 3 mm to 10 mm. By setting the distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4 to be 3 mm to 10 mm, the distance is relatively large, which can increase the insulation distance between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4, help reduce the possibility of electrical interference and mutual interference between the live wire electrical connection piece 3 and the neutral wire electrical connection piece 4, and improve the safety of the power adapter.

[0048] As Figure 2 and Figure 7 shown, the housing 1 includes a front shell 11 and a base shell 12. The front shell 11 covers the base shell 12, and the socket base 2 is installed in the base shell 12; the power adapter includes a shielding component 5. The mounting cavity 21 includes at least two live wire cavities 211 and two neutral wire cavities 212. One live wire cavity 211 and one neutral wire cavity 212 are arranged side by side, and the other live wire cavity 211 and the other neutral wire cavity 212 are arranged side by side; the electrical connection portions 31 of the live wire electrical connection piece 3 are installed in the two live wire cavities 211, and the electrical connection portions 31 of the neutral wire electrical connection piece 4 are installed in the two neutral wire cavities 212. Corresponding to each live wire cavity 211 and neutral wire cavity 212 of the socket base 2, jacks 111 are provided on the front shell 11. The shielding component 5 includes a first shielding member 51 and a second shielding member 52. The first shielding member 51 and the second shielding member 52 can be slidably installed on one side of the socket base 2 close to the jacks 111. The first shielding member 51 and the second shielding member 52 are elastically connected to each other, so that the first shielding member 51 shields one side-by-side live wire cavity 211 and neutral wire cavity 212 under the action of elastic force, and the second shielding member 52 shields the other side-by-side live wire cavity 211 and neutral wire cavity 212 under the action of elastic force.

[0049] The housing 1 is composed of a front shell 11 and a base shell 12. The front shell 11 covers the base shell 12. The socket base 2 is installed in the base shell 12, so that the internal components of the power adapter can be well protected, and it is convenient for the installation and maintenance of the socket base 2. The elastic connection between the first shielding member 51 and the second shielding member 52 can ensure the shielding of the jacks 111 of the corresponding live wire cavity 211 and neutral wire cavity 212, improving the safety performance of the power adapter. When the pin of the plug is inserted into the corresponding jack 111, the corresponding first shielding member 51 or second shielding member 52 is forced to move and open the jack 111.

[0050] As Figure 7 shown, the shielding assembly 5 includes an elastic member 53. The elastic member 53 is arranged between the first shielding member 51 and the second shielding member 52 and is respectively connected to the first shielding member 51 and the second shielding member 52. Two parallel insertion posts 511 and corresponding slots 512 are provided on the first shielding member 51 and the second shielding member 52. The two insertion posts 511 can be respectively movably inserted into the two slots 512; the elastic member 53 is located between the two insertion posts 511. By providing two parallel insertion posts 511, it can be ensured that the first shielding member 51 and the second shielding member 52 need to be pushed to open the first shielding member 51 or the second shielding member 52 when the pins of the plug are simultaneously inserted into the corresponding live wire cavity 211 and neutral wire cavity 212. If only the first shielding member 51 or the second shielding member 52 corresponding to one of the live wire cavity 211 and the neutral wire cavity 212 is stressed, since the first shielding member 51 or the second shielding member 52 will tilt and get stuck to the other side due to unbalanced force, the first shielding member 51 or the second shielding member 52 cannot be smoothly opened. In this way, it can be ensured that only when the first shielding member 51 or the second shielding member 52 corresponding to the live wire cavity 211 and the neutral wire cavity 212 is simultaneously pushed can the jack 111 be opened, improving the safety of the power adapter. The insertion of the insertion post 511 into the slot 512 can ensure the stability of the telescopic movement of the insertion post 511. Specifically, the elastic member 53 can be a spring.

[0051] As Figure 7 shown, a clamping protrusion 511a is provided at the end of the insertion post 511. The clamping protrusion 511a is located in the slot 512 and is used to resist against the slot 512. The clamping protrusion 511a can prevent the insertion post 511 from disengaging from the slot 512, facilitating the assembly of the first shielding member 51 and the second shielding member 52.

[0052] As Figure 7As shown, inclined surfaces 54 are provided on the surfaces of the first shielding member 51 and the second shielding member 52 corresponding to the jacks 111 inserted into the live wire cavity 211 and the neutral wire cavity 212, facilitating the pushing open of the first shielding member 51 or the second shielding member 52 when the plug pins are inserted. Protrusions may be provided on the sides of the first shielding member 51 and the second shielding member 52 facing away from the jacks 111. An installation concave cavity 24 starts from one side of the socket holder 2 facing the jacks 111, and the first shielding member 51 and the second shielding member 52 are installed in the installation concave cavity 24. Sliding grooves are provided in the installation concave cavity 24, and the protrusions of the first shielding member 51 and the second shielding member 52 are embedded in the sliding grooves to improve the sliding stability of the first shielding member 51 and the second shielding member 52.
