[0002] Nowadays, there are many specifications and types of plugs for various electrical products. Especially when there are different electrical usage standards in different countries and regions, the specifications of plugs and sockets are usually different. They can generally be divided into two-pin types and three-pin types, and there are also many differences in the arrangement and shape of the pins. The cross-section can be circular or strip-shaped. Therefore, when the original plug of an electrical appliance in one country needs to be used in different countries, it usually cannot be directly used.
[0003] Now people have developed conversion plugs with multi-country specification pins and set universal sockets for users to use conveniently. For convenient and safe use, the unused sockets are stored in the conversion plug. When in use, the pins with matching specifications are unfolded. The unfolded pins are conducted with the electronic components inside the conversion plug, the unfolded pins are plugged into the power socket, and are transferred through the electrical components in the conversion plug, and finally output through the jacks of the conversion plug. However, there are the following safety problems: when one of the pins is conductively connected to the power socket, the other pins with different specifications can be normally unfolded and can be conducted with the electronic components inside the conversion plug at the same time.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0034] Please refer to Figures 1 to 11 , an embodiment provided by the present invention: a travel socket with high safety performance, including a socket body 10 and a conductive component 20 and a clamping component 30 arranged in the socket body 10.

Among them, the clamping component 30 and the conductive component 20 are installed in the installation cavity.
[0035] When the first conductive part 21 slides downward, the first pin 211 extends outward from the socket body 10, driving the first clamping part 31 to move toward the center direction. The first clamping part 31 abuts against the second clamping part 32 and holds the second clamping part 32 to prevent the second conductive part 22 from sliding downward, that is, the two second contact parts 222 cannot contact and conduct with the two conductive metal sheets 26. The two first contact parts 212 on the first conductive part 21 respectively abut against the two conductive metal sheets 26 to realize electrical conduction between the first pin 211 and the clamping metal sheet 28; at the same time, the first barb part 34 is inserted into the first limiting groove 234 on the third conductive part 23 to prevent the third conductive part 23 from flipping outward, that is, the two third contact parts 232 cannot contact and conduct with the two conductive metal sheets 26, further improving the safety performance of the travel socket.
[0036] When the second conductive part 22 slides downward, the second pin 221 extends outward from the socket body 10, driving the second clamping part 32 to move toward the center direction. The first clamping part 31 abuts against the second clamping part 32 and holds the first clamping part 31 to prevent the first conductive part 21 from sliding downward, that is, the two first contact parts 212 cannot contact and conduct with the two conductive metal sheets 26. The two second contact parts 222 on the second conductive part 22 respectively abut against the two conductive metal sheets 26 to realize electrical conduction between the second pin 221 and the clamping metal sheet 28; at the same time, the second barb part 35 is inserted into the second limiting groove 235 on the third conductive part 23 to prevent the third conductive part 23 from flipping outward, that is, the two third contact parts 232 cannot contact and conduct with the two conductive metal sheets 26, further improving the safety performance of the travel socket.
[0037] The third conductive part 23 is turned outward by 90°, the two third pins 231 are unfolded outward and perpendicular to the socket body 10, and the two third contact parts 232 are in contact with the conductive metal sheet 26, realizing the electrical conduction between the third pin 231 and the clamping metal sheet 28.

When the first plug pin 211 is needed, the user presses the first pressing part 215 toward the center direction, and the first resistance part 213 is disconnected from the inner wall of the shell, and the first conductive part 21 slides in cooperation with the guide part 11 and the guide groove 12, and the first connection part 214 slides downward along the first slide groove 13, and the top of the first conductive part 21 is engaged with the first clamping groove 311 on the first clamping part 31, and the first resistance part 213 is in contact with the inner end surface of the shell, so that the first conductive part 21 is fixed, and the power socket can be plugged in through the first plug pin 211.
[0043] The second conductive part 22 is provided with a second elastic structure (not shown), and the second elastic structure is connected with a second resisting part 223, a second connecting part 224 and a second pressing part 225 in sequence.

The circuit board 24 and the conductive metal sheet 26 are isolated from high voltage and low voltage by the insulating sheet 25, thereby improving the safety performance of the socket body 10. The two conductive metal sheets 26 are in an inverted "U" shape. The shape of the conductive metal sheet 26 facilitates the contact and connection between the first conductive part 21, the second conductive part 22 and the third conductive part 23.
