Moreover the design such as the groove by assembling type plug, snap fit can further make assembling type plug firmly be combined with convertor assembly.And, as long as groove is separated with projection and along the glide direction application of force, assembling type plug can be separated with convertor assembly.

In addition, respectively be formed with railroad shoe by the first shell and second housing, so that the user complies with its demand, and described assembling type plug be inserted in the railroad shoe of the first shell or the railroad shoe of second housing.

And described the first shell and second housing also can respectively be formed with rail groove, and assembling type plug forms the slide block of respective carter groove, so that assembling type plug is when being inserted in the first shell or second housing, by the collocation of rail groove and slide block, further promote the bond stability of assembling type plug and convertor assembly.

The above only is embodiment of the present utility model, and it is not to limit to protection range of the present utility model.
