[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] The embodiment of the present application provides a novel conversion head socket.

[0028] See also Figure 1 In the embodiment of the present application, a new type of conversion head socket includes a shell 1, a plug assembly 2 and a positioning pin assembly 3. The positioning pin assembly 3 and the plug assembly 2 are arranged at the same end surface of the shell 1 at an interval. The plug assembly 2 is electrically connected to the carrier socket to connect the power cord to energize it. The positioning pin assembly 3 is used to align with the carrier positioning hole on the carrier socket to ground and enhance the safety of electricity use.

[0029] See also Figure 1 and Figure 2 The housing 1 includes an end cover and a base, which are fixedly connected to each other, and the end cover and the base enclose a receiving chamber 13. The plug assembly 2 and the positioning pin assembly 3 are both installed on the end cover, and a part of the plug assembly 2 is located in the receiving chamber 13, and another part is located outside the receiving chamber 13. The housing 1 is provided with a plurality of mounting holes 15 corresponding to the plug assembly 2, and the mounting holes 15 are connected to the receiving chamber 13. There are three mounting holes 15, and the three mounting holes 15 are arranged in a triangular shape.

[0030] The plug assembly 2 can be a two-cornered plug or a triangular plug. In the present embodiment, the plug assembly 2 uses a three-pin plug. The plug assembly 2 includes a hot pole pin 21, a zero pole pin 22 and a ground pole pin 23. The hot pole pin 21, the zero pole pin 22 and the ground pole pin 23 are arranged corresponding to the three mounting holes 15 one by one, and the hot pole pin 21, the zero pole pin 22 and the ground pole pin 23 are all passed through the mounting holes 15. The hot pole pin 21 and the zero pole pin 22 are arranged side by side, and the ground pole pin 23 is located above the hot pole pin 21 and the zero pole pin 22. The hot pole pin 21, the zero pole pin 22 and the ground pole pin 23 are arranged in a triangle. A plurality of mounting seats 16 are provided on the end face of the housing 1 of the earth electrode pin 23 facing the accommodating chamber 13, and there are three mounting seats 16. The fire electrode pin 21, the zero electrode pin 22 and the earth electrode pin 23 located at one end of the accommodating chamber 13 are all arranged in one-to-one correspondence with the mounting seats 16 and are mutually engaged to limit the fire electrode pin 21, the zero electrode pin 22 and the earth electrode pin 23 to prevent the fire electrode pin 21, the zero electrode pin 22 and the earth electrode pin 23 from detaching from the housing 1.

[0031] See also Figure 1 and Figure 3 The housing 1 is provided with a mounting groove 11 at a position corresponding to the positioning pin assembly 3. The bottom of the mounting groove 11 is connected to the accommodating chamber 13. The mounting hole 15 and the mounting groove 11 are provided on the same end surface of the housing 1, namely, on the end cover. The positioning pin assembly 3 is installed in the mounting groove 11. The plug assembly 2 is located at one end of the mounting groove 11 along the length direction. The length of the mounting groove 11 is the travel range of the positioning pin assembly 3. The length direction of the mounting groove 11 is the same as the length direction of the end cover. The positioning pin assembly 3 moves toward or away from the plug assembly 2 along the length direction of the mounting groove 11 to correspond to the carrier positioning holes in the carrier socket that are inconsistent with the carrier electrical connection holes, thereby expanding the adaptability of the adapter socket and providing users with more usage scenario options.

[0032] See also Figure 2 and Figure 3The positioning pin assembly 3 includes a positioning pin 31, a gasket 32 ​​and a connector 34. The positioning pin 31 is located on the side of the ground electrode pin 23 away from the live electrode pin 21 and the zero electrode pin 22, that is, the positioning pin 31 is located above the ground electrode pin 23, and the central axis of the positioning pin 31 and the central axis of the ground electrode pin 23 are located in the same plane. The gasket 32 ​​is located in the accommodating chamber 13, and the gasket 32 ​​is located at one end of the positioning pin 31. The gasket 32 ​​is detachably mounted on the positioning pin 31 through the connector 34, and the positioning pin 31 is slidably connected to the housing 1 through the mounting groove 11. Specifically, the positioning pin 31 includes a connecting end and a positioning end. The positioning pin 31 passes through the installation groove 11. The positioning pin 31 moves closer to or away from the plug assembly 2 along the length direction of the installation groove 11. The connecting end is located in the accommodating chamber 13, and the positioning end is located outside the accommodating chamber 13. In this embodiment, the gasket 32 ​​is located at the connecting end, and the connecting member 34 is preferably a screw. The positioning pin 31 is provided with an internal thread that matches the screw. The screw passes through the gasket 32 ​​and is threadedly connected to the positioning pin 31, so that the gasket 32 ​​can be detachably installed on the positioning pin 31.

[0033] In order to enhance the installation stability of the locating pin 31, a boss 12 is provided on the peripheral wall of the mounting groove 11, and a limiting block 311 is provided on the locating pin 31. The limiting block 311 is located on the side of the boss 12 away from the accommodating chamber 13, and the end faces of the limiting block 311 facing the mounting groove 11 are both in contact with the end faces of the mounting groove 11 facing the limiting block 311; a clamping gap 33 is formed between the limiting block 311 and the gasket 32, the boss 12 is located in the clamping gap 33, and the boss 12 contacts and presses against the limiting block 311 and the gasket 32 ​​respectively. The limit block 311 and the gasket 32 ​​cooperate with each other to clamp the boss 12, thereby limiting the tendency of the positioning pin 31 to move along its central axis. The limit block 311 fits the inner wall of the mounting groove 11 to limit the tendency of the positioning pin 31 to move in the lateral direction of the mounting groove 11, so that the positioning pin 31 can only move along the length direction of the mounting groove 11 to adjust the distance between the positioning pin 31 and the ground pin 23 to adapt to the carrier positioning hole in the carrier sockets of different standards in various countries, so that the positioning pin 31 can be aligned with the carrier positioning hole and inserted.

[0034] Furthermore, an escape seat 14 is provided at one end of the installation slot 11 facing the accommodating chamber 13. The escape seat 14 is integrally formed with the housing, and the escape seat 14 is arranged around the periphery of the installation slot 11 and is coaxially arranged. The distance between the upper end surface of the escape seat 14 and the inner wall of the housing 1 is greater than the distance between the upper end surface of the connecting member 34 and the inner wall of the housing 1. The escape seat 14 reserves sliding space for the positioning pin assembly 3 on the one hand, and reduces the circuit fault caused by the contact between the internal components of the adapter socket and the positioning pin assembly 3 on the other hand.

[0035] The shell 1 is provided with multiple jacks, and the jacks and mounting holes 15 are located on different end faces of the shell 1, that is, the jacks are arranged on each end face of the base. The number of jacks can be set according to needs. The plug of the electrical appliance is electrically connected to the adapter through the jack to achieve current connectivity.
