[0021] In order to make the technical content, construction features and effects of the present application clear, the following will be described in detail in combination with the embodiments and the drawings.
[0022] Please refer to Figures 2 to 5 The travel socket 100 of the present application comprises a shell 1, a first prong assembly 2, a second prong assembly 3, a third prong assembly (not shown in the figure), a socket assembly (not shown in the figure) and a connecting terminal (not shown in the figure). The first prong assembly 2, the second prong assembly 3 and the third prong assembly are respectively arranged in the shell 1 in a sliding and telescopic manner, and the connecting terminal is connected between the socket assembly and each prong assembly. The socket assembly is provided with a corresponding socket hole for each prong assembly. After the electrical equipment is plugged into the corresponding socket hole of the socket assembly, the electrical equipment is electrically connected with the corresponding prong assembly through the connecting terminal. The first prong assembly 2 is a European prong, the second prong assembly 3 is a British prong, and the third prong assembly is an American prong. The first prong assembly 2 comprises a prong sleeve 21, the bottom surface of the shell 1 is provided with a containing hole 11, and the prong sleeve 21 is arranged in the shell 1 in a sliding and telescopic manner and extends through the containing hole 11 when it is extended. The bottom surface of the prong sleeve 21 is provided with a through hole 211, and the through hole 211 is completely located on the prong sleeve 21. The second prong assembly 3 comprises a second prong 31, and one of the second prongs 31 is arranged in the prong sleeve 21 and is arranged in the through hole 211 in a telescopic manner.
[0023] Please refer to Figure 3 , Figure 6 , Figure 7 and Figure 9, specifically, the first pin assembly 2 further comprises a pair of first pins 22 and a first insulation support 23, one end of the two first pins 22 and the sleeve 21 are arranged on the first insulation support 23, the other end of the two first pins 22 is arranged in the sleeve 21 and passes through the round hole 213 of the sleeve 21. The first insulation support 23 is arranged in the shell 1 to push the two first pins 22 and the sleeve 21 to extend out of or retract into the shell 1. Specifically, the sleeve 21 is provided with a guide slot 212 along the sliding direction thereof, the first insulation support 23 is provided with a sliding part 231, the sliding part 231 is arranged in the guide slot 212. When the first insulation support 23 pushes the first pins 22 to extend out of the shell 1, the sliding part 231 slides in the guide slot 212, at this time, the sleeve 21 is still fixed relative to the shell 1, when the sliding part 231 slides to the lower end of the guide slot 212, the sliding part 231 pushes the sleeve 21 to extend out of the shell 1, that is, the first insulation support 23 first pushes the first pins 22 to extend out of the shell 1, and then pushes the sleeve 21 to extend out of the shell 1. Conversely, when the first insulation support 23 pushes the first pins 22 to retract into the shell 1, the first pins 22 are first pushed to retract into the shell 1, and then the sleeve 21 is pushed to retract into the shell 1 when the sliding part 231 slides to the upper end of the guide slot 212.
[0024] Further referring to Figure 3 、 Figure 4 、 Figure 8 and Figure 9The second pin assembly 3 further comprises a second insulating support 32, and the number of the second pins 31 is three; one end of the three second pins 31 is arranged on the second insulating support 32, and the second insulating support 32 is arranged in the shell 1 in a sliding mode to push the three second pins 31 to extend out of or retract into the shell 1; the bottom surface of the shell 1 is provided with two insertion holes 12, and in addition, the two second pins 31 are arranged in the insertion holes 12 in a retractable mode. More specifically, the three second pins 31 are respectively a positive pin, a negative pin and a ground pin. The positive pin and the negative pin are inserted into the insertion holes 12, and the ground pin is inserted into the through hole 211. The shell 1 is provided with a guide column, the second insulating support 32 is provided with a guide sleeve 321, and the guide sleeve 321 is arranged on the guide column 13 in a sliding mode. When the second insulating support 32 is pushed to move downward, the second insulating support 32 drives the positive pin and the negative pin to extend out of the insertion holes 12 and drives the ground pin to extend out of the through hole 211. Conversely, when the second insulating support 32 is pushed to move upward, the second insulating support 32 drives the positive pin and the negative pin to retract into the insertion holes 12 and drives the ground pin to retract into the through hole 211.
[0025] One of the second pins 3 is arranged in the sleeve 21, and a through hole 211 is further arranged on the bottom surface of the sleeve 21 of the first pin assembly 2, so that one of the first pins 22 of the second pin assembly 3 is arranged in the through hole 211 in a retractable mode, so that the first pin assembly 2 and the second pin assembly 3 can be combined with each other, so as to fully utilize the internal space of both, and the structure is very compact, so that the volume of the travel socket 100 is smaller than that of a traditional travel socket, and the travel socket 100 is very convenient to carry.
[0026] The structure of the third pin assembly and the connecting terminal involved in the travel socket 100 of the utility model are well known to those skilled in the art, and will not be described in detail here.
[0027] The above disclosure is only a preferred example of the utility model, and of course cannot limit the scope of the utility model, so equivalent changes made in the scope of the utility model patent application still belong to the scope covered by the utility model.
