[0043] Please refer to Figures 1 to 19 The utility model discloses a pin combination structure for power converter and smaller, including setting in a european pin assembly 1 of power converter, and setting in an english pin assembly 2 of power converter, the english pin assembly 2 includes setting in an english ground pin 21 of power converter, the european pin assembly 1 includes setting in a european plug sleeve 11 of power converter, the middle part of european plug sleeve 11 is formed with the inward recess and matches with english ground pin 21 a english ground let room slot 111, english ground pin 21 in english ground let room slot 111 is carried out up and down activity, so that english ground pin 21 can be pushed out in european plug sleeve 11 when needing, save the space in power converter, make power converter smaller, more convenient for travel carrying, improve the use experience of power converter.

[0044] For the specific structure of english ground let room slot 111, as Figures 2 to 4 And Figure 6 Show, english ground let room slot 111 is whole and presents a few characters, and its both sides are connected with european plug sleeve 11, and its outside forms a square movable space, and the square movable space is matched with the shape of english ground pin 21, so that english ground pin 21 is limited and can only carry out radial motion, improve the precision of english ground pin 21 protruding, prevent the situation of poor contact because of displacement.

[0045] For the specific structure of european pin assembly 1, as Figures 2 to 9As shown, the European plug assembly 1 further comprises a European connector 12 slidingly arranged in the European plug sleeve 11, a European key member 13 slidingly connected to the European connector 12, a European live plug 14 arranged on the European connector 12, and a European neutral plug 15 arranged on the European connector 12. When the European plug assembly 1 needs to be used, the European key member 13 can be pressed to drive the European plug sleeve 11 to protrude out of the power converter, and the European connector 12, the European live plug 14 and the European neutral plug 15 connected to the European key member 13 are pushed out of the power converter along the European plug sleeve 11 for power conversion. When the European plug assembly 1 does not need to be used, the European key member 13 is pressed to reversely push the European live plug 14 and the European neutral plug 15 connected to the European key member 13, as well as the European plug sleeve 11, back into the power converter for storage. The whole process is simple and convenient, and the user experience is good.

[0046] In order to prevent the British ground plug 21 from resisting the European plug assembly 1 when the European plug assembly 1 is pushed out, causing the European plug assembly 1 to be unable to protrude for use, as shown in Figures 2 to 6 and Figure 11 As shown, a European push-out accommodation channel 16 is formed between the European connector 12 and the European key member 13 for accommodating the British ground plug 21. When the European plug assembly 1 is to be pushed out of the power converter for use, the European connector 12 and the European key member 13 move towards the outside of the power converter, the top end of the British ground plug 21 enters the European push-out accommodation channel 16, and the tail end of the British ground plug 21 enters the British ground accommodation slot 111, thereby achieving accommodation and preventing the British ground plug 21 from resisting the European plug assembly 1 when the European plug assembly 1 is pushed out, causing the European plug assembly 1 to be unable to protrude for use.

[0047] In order to further improve the accuracy of pushing and pushing out of the European plug assembly 1, as shown in Figure 5As shown, the European plug 12 is formed with at least one European limiting protrusion 121 on the side away from the British pin assembly 2, the European sleeve 11 is formed with a limiting backboard 112 on the side away from the British pin, and the middle of the limiting backboard 112 is formed with at least one European limiting sliding groove 113 for the movement of the European limiting protrusion 121. When the European key piece 13 drives the European plug 12 to advance and retract, the European limiting protrusion 121 slides in the European limiting sliding groove 113 and can only move radially under the limiting action of the European limiting sliding groove 113, so that the European plug 12 drives the European key piece 13 and the European zero line pin 15 and European fire wire pin 14 to move more accurately in the European sleeve 11, preventing the European pin assembly 1 from shifting during advancement and retraction.

[0048] For the specific way in which the European zero line pin 15 and the European fire wire pin 14 extend out of the European sleeve 11, as shown in Figure 1 As shown, the bottom of the European sleeve 11 is correspondingly formed with a European fire wire protruding opening 114 for the European fire wire pin 14 to protrude out of the power converter and a European zero line protruding opening 115 for the European zero line pin 15 to protrude out of the power converter. When the European pin assembly 1 is pushed out of the power converter, the European fire wire pin 14 extends out of the European fire wire protruding opening 114, and the European zero line pin 15 extends out of the European zero line protruding opening 115. The corresponding limiting protruding cooperation of the European fire wire protruding opening 114 and the European zero line protruding opening 115 with the movement of the European limiting protrusion 121 in the European limiting sliding groove 113 makes the European pin assembly 1 more accurately advance and retract in the power converter, improving the activity efficiency of the European pin assembly 1.

[0049] In order to make the European pin assembly 1 slide better in the power converter, as shown in Figure 8 and Figure 9As shown, the power converter comprises a shell 4, an inner wall of the shell 4 is formed with a European plug push-out limiting column 41 matched with the European plug assembly 1, one end of the European plug sleeve 11 towards the inner wall of the shell 4 is formed with a European plug push-out limiting groove 116 matched with the European plug push-out limiting column 41; the European plug key piece 13 is formed with a European plug push-out limiting block 133 movably abutting on the European plug push-out limiting column 41.
