The described latch back side is provided with projection, the inboard corresponding draw-in groove that forms of described slot upper wall, and described projection snaps in the draw-in groove.

Described fluting is the pair of parallel groove, and described cutting is that pair of parallel is transplanted a cutting.

Described projection is the strip perpendicular to fluting.

The described projection and the latch back side are a slick and sly curvature.

Form a step between described latch and the insulating body end face, this step and slot upper wall edge support.

Described main body is square box body, and its sidepiece is provided with mounting groove, and the concave surface of this mounting groove and first surface of shell connects, and the plug on the latch snaps in this mounting groove and inserts in the socket of body interior.

The concave surface of described first surface of shell is square, and latch is square.

The beneficial effects of the utility model are as follows: cooperate, transplant a cutting and engaging of slotting with concave surface and slot because of power supply adaptor of the present utility model adopts latch, and the grafting of plug and socket, thereby switching part is fixedly mounted on the main body, so adapter structure is stable, can power down.

Embodiment

See figures.1.and.2, power supply adaptor 100 of the present utility model comprises switching part 10 and main body 20, and switching part 10 is plugged in main body 20 1 ends.Main body 20 is greatly most square but be not limited to squarely, and it comprises first housing 30 and second housing 50, is covered by two

housings

30 and 50, and socket 40 and circuit board (not shown) are set in it.Socket 40 is arranged on the housing side, pegs graft with switching part 10, thereby external power source is electrically connected with internal circuit.

With reference to Fig. 3, first housing, 30 tops are provided with concave surface 32 simultaneously, and concave surface 32 extends to form slot 33 forward, the slot 33 upper walls 31 inboard draw-in grooves 34 that form.Slot 33 inside bottom wall form a pair of cutting that is parallel to each other 35.

Housing

30,50 sidepieces all offer mounting groove (not icon) to assemble with switching part 10, and the concave surface 32 of the mounting groove and first housing 30 connects.

Please be simultaneously with reference to Fig. 4 and Fig. 5, switching part 10 comprises insulating body 1, latch 2, pin 3, plug 6.Pin 3 be plugged in external power source, it is shaped in this insulating body 1.Plug 6 is fixed on this insulating body 1 by latch 2, and the socket 40 of itself and main body 20 inside plugs.This latch 2 is greatly to being square but be not limited to squarely, and it is fixed on the end face of insulating body 1 abreast, and is opposing with pin 3.The effect of latch 2 is further switching part 10 to be fixed on first housing 30 of main body 20, for this reason, thereby forms a step 7 between extension of latch 2 tip forward and insulating body 1 end face, and therefore, step 7 is positioned at the back side of latch 2.The terminal parallel fluting 5 of offering of latch 2, latch 2 is provided with projection 4 with respect to the back side of insulating body 1 end face.Be appreciated that this projection 4 can be and the 5 vertical strips of slotting, and also can be arranged on the projection on latch 2 back sides.In the present embodiment, projection 4 is and fluting 5 vertical strips, and is a slick and sly curvature with latch 2 back sides, is beneficial to chucking and extracts.

Referring again to Fig. 2 and Fig. 3, during adapter 100 assemblings, the plug 6 of its switching part 10 snaps in the mounting groove of main body 20 sidepieces and is plugged in the socket 40 of main body 1 inside, latch 2 inserts in the slot 33 along the concave surface 32 on first housing, 30 surfaces, when the edge of the step 7 at latch 2 back sides and slot 33 roofs 31 holds, send a sound, at this moment, engaging puts in place, latch 2 terminal insertions in the slot 33, projection 4 snaps in the draw-in groove 34, and cutting 35 is inserted in the fluting 5, thereby latch 2 is retained in first housing, 30 concave surfaces 32 tightly, and plug 6 is by housing 30, the socket 40 of mounting groove main body 20 inside of 50 sides is pegged graft.Thereby switching part 10 is fixedly mounted on the main body 20.
