New Description: [New Technology Field] This creation relates to a micro USB connector, and more particularly to a micro USB connector capable of effectively blocking the insertion force generated when the plug is inserted to cause the insulating body to be pushed out. [Prior Art] Micro USB connectors are commonly used for data transmission between products such as mobile phones, digital cameras, etc., and the traditional MINI USB connector and the Phone Plug are integrated together, which has a small size. , features strong features. According to the prior art, the micro USB connector includes an insulating body, a conductive terminal fixed on the insulating body, and a metal case covering the insulating body. The insulating body has a front wall, a rear wall, a top wall, a bottom wall and two side walls. The front wall of the insulative housing projects forward to form a plate-like retaining portion. The insulating body is provided with a plurality of terminal slots extending rearward from the front end of the holding portion and extending through the insulating body. The corresponding terminals of the conductive terminals are fixed in the terminal slots of the insulating body. A metal casing covers the insulative housing to shield external electromagnetic interference. However, when the docking plug is inserted into the micro USB connector, the over insertion force applied to the plug easily pushes the plug against the insulating body in the micro USB connector, thereby pushing the insulating body out of the metal casing, thereby damaging the miniature 5 M322654 USB. Connector. [New Content] The purpose of this creation is to provide a micro USB connector capable of preventing the insulative body from being pushed out when the mating plug is inserted, in view of the deficiencies of the above-mentioned prior art. In order to achieve the above object, the micro USB connector provided by the present invention is inserted into a corresponding plug having a metal casing. The micro USB connector includes an insulative housing, a conductive terminal interposed on the insulative housing, and a metal outer casing covering the insulative housing. The metal casing encloses an accommodation space. The metal casing extends into the accommodating space a blocking portion that can abut against the front end of the metal casing of the corresponding mating plug. As described above, when the micro USB connector and the docking plug are nested and inserted into each other, the plug is inserted into the accommodating space, and the front end of the metal casing of the plug is abutted against the blocking portion to avoid the metal shell of the plug. The body is in contact with the insulating body of the micro USB connector, so that the over-insertion force exerted on the plug can be prevented from pushing the insulating body of the micro USB connector out of the metal casing. [Embodiment] In order to explain in detail the technical contents, structural features, achieved goals and effects of the present invention, the following is a detailed description with reference to the drawings. 6 M322654 Referring to the first figure, the micro USB connector of the present invention comprises an insulating body 100, a plurality of conductive terminals interposed on the insulating body 1〇〇, and a metal case 300 covering the insulating body 1〇〇. Referring to the second and third figures, the insulative housing is an integrally formed member having a front wall 111, a rear wall 112, a top wall 113, a bottom wall 114 and two side walls 115. The front wall lu of the insulative housing 1 protrudes forwardly from a plate-like holding portion 120. A plurality of terminal slots (not shown) extending through the insulative housing 1 are opened rearward from the front end of the holding portion 120. The retaining portion 120 further defines two rows extending through the retaining portion 12 and communicating with the corresponding terminal slots. Opening 121. A central portion of the top wall 113 of the insulative housing 1 protrudes outwardly from a strip-shaped opening 116 having a u-shaped opening. The front portion of the top wall 113 of the insulative housing 1 has a slot 117 penetrating the front wall downwardly on both sides of the clip 11 β and the holding portion 12 . The conductive terminal 200 is inserted into the corresponding terminal slot, and the front end of the conductive terminal 200 extends into the corresponding opening ι21. Referring to the second and fourth figures, the metal casing 3 has a top plate 311, a bottom plate 312, and two side plates 313. The plates 311, 312, and 313 define an accommodating space 400. Both ends of the rear portion of the top plate 311 are bent downward and extend rearwardly out of the first soldering leg 314. In the middle of the rear portion of the top plate 311, a card 315 which extends forward and downward from a free end is punched out. The card 315 is inserted into the opening of the card strip 116 of the insulative housing M322654 loo and abuts against the strip 116 to secure the insulative housing 1 in the receiving space 400. On the two sides of the front portion of the card 315, a hole 317 is punched in the top plate 311. The top plate 311 is bent downwardly at the front edge of the hole 317 and then bent forward to form a U-shaped blocking portion 316. The blocking portion 316 is located at the slot 117 of the insulative housing 1 , and at least a portion thereof is located in front of the front wall U1 of the insulative housing 100. When the present micro USB connector and the mating plug 20 are nested with each other, Inserting the plug 20 into the accommodating space 400, the front end of the metal housing of the plug 2 abuts against the blocking portion 316 to prevent the metal housing from abutting the insulating body 1 〇〇, thereby avoiding application to the plug 2 The over-insertion force pushes the insulating body 1 of the micro USB connector out of the metal casing 3 〇〇. 第五 See the fifth and sixth figures, which discloses a second embodiment of the present creation, this embodiment and the An embodiment is similar in that: the top plate 311 is bent downward at a rear edge of the hole 317 to extend a strip-shaped blocking portion 316 perpendicular to the top plate 311 and the side plate 313. Figure and Figure 8 'which reveals a third embodiment of the present work' Embodiment is similar to the first embodiment, except that it: a top plate 311 extending downwardly bent side edge of the aperture of a vertical slot 317 parallel to the top plate 311 and stopper portion 316 of the side plates 313.
