The main body portion 61 is provided with a longitudinal rib 6H which protrudes rearward and extends in the up-and-down direction, and two sides above the position=rib 611 are provided with two snap holes for engaging with the shielding shell 7=2 ( As shown in the second figure, and on both sides below the rib 611, and extending downwardly, the connecting leg 613 of the insulating body glazing 14 is connected to the circuit board. The rib 611 can provide the main body portion 61 with better strength and is less likely to be deformed. The connecting portion 62 is received in the receiving groove 185 of the third receiving cavity, and the connecting portion 62 can be insulated by being arranged. The body has a better stable retention effect. The connecting portion 62 is located above the horizontal portion 52 of the second fixing block 5. The connecting portion: 2 is provided with a latching portion 621 extending upwardly for matching the two latching holes above the top wall of the first housing 2, and the metal back cover 6 is not easily rearward. Out of the insulation body]. The lap joint portion 2 for pressing against the top wall 21 of the first casing 2 is also protruded from the two sides of the buckle portion =21. By means of the arrangement, the connecting portion 62 can be firmly connected to the first casing 2, and when the excess charge is generated on the first casing 2, the electric charge can be quickly charged by the metal back cover 6 provided with the connecting leg 613. Walk away and achieve good grounding. The side flaps 63 are further provided with a locking leg 631 extending into the front side of the insulative housing i for engaging in the stepping hole 15]. If the arrangement is performed, the main part of the metal back cover 6 is arranged. & can be stably held with the insulation body. Since the connecting leg 6ί3 and the latching leg 63ΐ are respectively extended downward M3 51490 and forwardly, the extending directions thereof are perpendicular to each other, so that the metal back cover 6 can be more stably stabilized after being mounted and fixed. Referring to the third to fifth figures, the shielding shell 7 includes a top end wall 71 attached to the top surface 13 of the insulative housing 1 , and extends downward from both sides of the top end wall 71 and is attached to the insulative housing 1 . The side end walls 72 on the two side faces 15 and the front end 73 and the rear end wings 74 extend vertically inward from the front end wall 71 and the front end and the rear end side of the side end wall 72. The side end wall 72 is provided with a buckle portion 721 extending inwardly for engaging with the groove 152 of the two side faces 15 of the insulative housing 1. Thus, the shield housing 7 can be prevented from being separated upward from the insulation body. . The side end wall 72 is further provided with a retaining leg 722 extending downwardly from the mounting surface 14 of the insulative housing 1 for mounting to the circuit board. The front end wing 73 is attached to the side edge of the front end surface η of the insulative housing 1 , and the rear end wing 74 is attached to the side edge of the rear end metal housing 6 of the electrical connector 1 , thus preventing The shielding body 7 moves in the front-rear direction with respect to the insulative housing 1, and since the metal back cover 6 and the shielding case 7 overlap each other, the electrical connector 1 can be provided with a better masking effect. The front end wing is connected with the wall 72 and has a hollow portion 724. The front end wing 73 is bent inwardly at the adjacent hollow portion 724 to form a recess portion 723. The recess portion 723 is used for the recess portion 723. The side end wall 72 of the two sides is bent outwardly away from the two side faces 15 of the insulative housing i by being fastened to the ribs 111 of the front end surface 11 of the insulative housing i. The rear end wing 74 is provided with a buckle portion 741 extending inwardly for engaging with the metal back cover 6 fastening hole 6i2, so that the shielding shell 7 can be more stably and the metal back cover 6 Match. μ Please refer to the fifth to sixth inventions for the second connector 8 to be placed in the insulative body i = the first-receiving chamber A. The second connection || 8 includes an insulating block 82, a conductive terminal 83 mounted on the insulating block, and a second housing 84 sleeved on the insulating block 82. The insulating block 82 is convexly provided with a "[ The tongue plate 821', that is, the tongue plate 821, includes a flat plate portion 824 and an extension portion 825 extending perpendicularly from the plate. If it is arranged, the butt plug can be prevented from being reversely inserted. An upper and lower side surface 822 is provided, and the upper and lower side surfaces 822 are recessed with a receiving groove (not shown) for receiving the lower end. The second housing 84 is formed with a first/child-side interface 81 including a top wall 841, a bottom 842 opposite the top wall 841: a side wall between the bottom wall 842 and the bottom wall 842 Wherein - the side wall 843 and the bottom wall 842 are inclined sloping walls 844. The second connector plug can be reversed by the arrangement. The top wall 841, the bottom wall 842, and the two side walls 843 are each provided with a yoke extension 845. _(4) 绝 绫 绫 笋 笋 笋 笋 笋 笋 笋 笋 笋 八 八 八 八 八 八 八 八 八 八 八 八 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓 弓10 M351490, the second connector 8 is held on the insulative housing. In the embodiment, the second connector body 1 is, of course, in other embodiments, The insulating body 1 is integrally formed into the insulating body. The insulating block 82 having the electrical connection of 1 can also be combined with the above, and the creation conforms to the new: ^ also the second connector 8. The description is only for the creation of the present invention. Good example, the scope of this creation = no application. However, the above [simplified description of the diagram] The first picture is the three-dimensional combination diagram of the creative electrical connector; Fig. = three diagrams of the creation of the f-connector, the sub-axis of the shell, the four brothers of the creation of the electrical connector, a partial exploded view of the creation of the electrical connector. The picture shows the three-dimensional exploded view of the creative electrical connector; The six figures are the three-dimensional exploded view of the angle of the creation of the electrical connector.
