The power converter is an adapter tool that, in use, inserts the power converter into the target receptacle and then inserts the target plug into the mating receptacle holes on the power converter to achieve conversion. The advent of current transformers has facilitated the life of people out of the country, especially when travelling across the limits, without having to deal with the problems caused by the non-matching between the plugs of the electronic devices they carry and the local sockets.In conventional current transformers, the contact pins are usually fixed and protrude. In current transformers having a plurality of contact pins, a plurality of contact pins must be set up and disconnected in order to avoid mutual interference between a plurality of contact pins.

Those skilled in the art can understand the concrete meaning of the above-mentioned terms in the present invention according to the specific circumstances.Embodiment 1Referring to FIGS. 1 to 12, an embodiment of the present invention provides a more compact pin combination structure of a power converter, comprising a US pin component 1 disposed in the power converter and a UK pin component 2 disposed in the power converter, the UK pin component 2 comprising a common UK slide seat 21 slidably disposed in the power converter and a UK protective conductor pin 22 disposed on the common UK slide seat 21; the common UK slide seat 21 being formed in a U-shape as a whole and forming a recess space 211 therein; and wherein the US pin component 1 comprises a common US slide seat 11 arranged in the current transformer and slidably arranged in the recess space 211, and wherein an inwardly recessed UK guard recess groove 111 matching the UK guard pin 22 is formed on the common US slide seat 11, and wherein the UK guard pin 22 moves along the UK guard recess groove 111. By disposing and sliding the US pin component 1 in the recess space 211, the space occupied by the US pin component 1 and the space occupied by the UK pin component 2 are overlapped, further the UK protector pin 22 moves linearly along the UK protector recess groove 111, thereby further saving the space occupied between the UK protector pin 22 and the US pin component 1 to reduce the entire length of the current transformer and reduce the entire volume of the current transformer, which is more conducive to being worn by the user when travelling.In order to make the power converter more practical, as shown in FIGS. 2 to 3, 5, 6, and 8, the contact pin combination structure of a power converter preferably further comprises an EU contact pin component 3 disposed in the power converter and sliding in the recess space 211, which comprises an EU common sliding seat 31 disposed in the power converter and sliding in the recess space 211, an EU outer conductor contact pin 32 disposed on the EU common sliding seat 31, and an EU neutral conductor contact pin 33 disposed on the EU common sliding seat 31. By disposing an EU pin component 3 in the power converter, the selectivity of the pins that can be selected for use is further improved to improve the convenience of the power converter, which facilitates use in traveling. When the EU pin component 3 needs to be used, only the common EU slide seat 31 needs to be pushed outward in response to the current transformer, so that the EU outer conductor pin 32 and the EU neutral conductor pin 33 are pushed out of the current transformer to realize the switching of the EU pin. The EU pin component 3 moves in the recess space 211, so that the space occupied by the EU pin component 3, the space occupied by the US pin component 1, and the space occupied by the UK pin component 2 are overlapped, thereby reducing the entire length of the power converter and reducing the entire volume of the power converter, which is more conducive to the wearing by the user when travelling.With respect to the specific method of electrically connecting between the EU pin component 3 and the power converter, as shown in FIGS. 2 to 3, 5, 6, and 8, the EU pin component 3 further

32 and the EU neutral conductor contact pin 33 to slide out, the EU outer conductor sheet 34 and the EU neutral conductor sheet 35 disposed in the EU common slide seat 31 follow the movement synchronously, so that the EU outer conductor sheet 34 and the EU neutral conductor sheet 35 are inserted into the conductive mechanism of the current transformer to realize a conductive electrical connection between the EU contact pin component 3 and the current transformer, and in the entire process, the conductivity is stable, and the conductive efficiency is improved.In order to further save the space in the power converter and facilitate the extraction of the EU pin component 3 for use, as illustrated in FIGS. 2 to 3, 5, 6, and 8, an EU conductor plate recess groove 212 recessed toward an end facing away from the recess space 211 is preferably formed on the UK common slide seat 21, in which the EU outer conductor plate 34 and the EU neutral conductor plate 35 move linearly when driven by the EU common slide seat 31, the EU outer conductor plate 34 and the EU neutral conductor plate 35 move upward and downward in the EU conductor plate recess groove 212, so that the space occupied by the EU outer conductor sheet 34 and the EU neutral conductor sheet 35 and the space occupied by the common UK slide seat 21 are overlapped to further save the space in the current transformer, reduce the entire length of the current transformer and reduce the entire volume of the current transformer, which is more convenient for wearing by the user during travel and facilitates the pushing out of the EU contact pin component 3 for use.With respect to other structural settings of the UK pin component 2, as shown in Fig. 6, the UK guard pin 22 is arranged at one end of the

US pin component 1 and the UK pin component 2, thereby reducing the overall length of the current transformer and reducing the overall volume of the current transformer, which is more conducive to wear by the user during travel.As for the specific manner of pushing out the UK pin component 2 from the current transformer, as shown in Fig. 6, on the UK common slide seat 21 there is arranged a UK

rods.Preferably, as shown in Figs. 1 to 2, the initial height of the EU pin control rod 311 is greater than the initial height of the UK pin control rod 213 and the initial height of the US pin control rod 112 to form an offset arrangement, thereby effectively avoiding the simultaneous pressing of multiple control rods.With respect to adjustment of the line structure in the power converter,
