Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, below now for example and conjunction with figs. is detailed gives explanation.

See also Fig. 1, the utility model micro USB connector 1 comprises a metal shell 10, an insulating body 20 and several conducting terminals 30.

See also Fig. 2 and Fig. 3, metal shell 10 by the metallic plate punching press, cut and bend and form, it has a roughly rectangular substrate 11, the front-end edge of substrate 11 tilts to be bent with one first guidance part 111.Offer three holes 112 on the substrate 11,112 peritreme bends inwards and is extended with a baffle plate 113 substrate 11 in the hole.Substrate 11 relative both side edges upwards bend and extend to form side plate 12 respectively, and the oblique outer bending of the front-end edge of side plate 12 is formed with one second guidance part 125.Biside plate 12 be extended with a cover plate 13 away from the relative bending of a lateral margin of substrate 11, the oblique outer bending of the front-end edge of cover plate 13 is formed with one the 3rd guidance part, 131, the three guidance parts 131 and second guidance part 125 and first guidance part, 111 guiding butt connectors and is inserted in the utility model micro USB connector 1.Offer a button hole 123 that extends to substrate 11 from the junction of side plate 12 and cover plate 13.All outwards bend at adjacent substrates 11 places of these button hole 123 peritremes and at the rear portion of this side plate 12 and to be extended with a weld part 124, weld part 124 is welded on the printed circuit board (PCB) (not shown) so that the utility model micro USB connector 1 is fixed.Cover plate 13, side plate 12 surround an accepting groove 14 with substrate 11.

Insulating body 20 has one and roughly is rectangular-shaped base portion 21.The front end face of base portion 21 outwards vertically protrudes out and forms a hyoplastron 211.Offer several terminal grooves 212 on the hyoplastron 211, and terminal groove 212 runs through base portion 21, offer the perforate 213 that runs through this hyoplastron 211 up and down on the diapire of terminal groove 212.The lower surface of base portion 21 offers three draw-in grooves 214.The upper surface rear portion of base portion 21 upwards protrudes out and is bent to form forward one and roughly is tabular lid 22, and the front end of lid 22 is parallel to base portion 21, thereby is formed with a storage tank 23 between this lid 22 and the base portion 21.The both sides of lid 22 front ends extend to form a buckling parts 24 downwards.
