Refer to Figure 19, 22, shown in 23, compared to embodiment one, the difference of the embodiment of the present application two is: in described metal isolation, the leg 62 of both sides, plate 60 ' rear end is removed, and in the isolation of described metal plate 60 ' the vertical bending in both sides, rear end after successively extend to form contact elastic arm 601, described contact elastic arm 601 comprise the vertical bending in both sides, plate 60 ' rear end in the isolation of described metal backward after the parallel extensions 602 that extends to form, and from the abutting pin 603 that the outside bending of the end of two parallel extensions 602 is formed, described abutting pin 603 is after described inner metal shell 12 ' is inserted in described insulation crust 80 ', in described metal isolation, abutting pin 603 end of plate 60 ' is electrically connected on the medial surface of described inner metal shell 12 ', described metal shell 11 ' is sheathed on described inner metal shell 12 ' and welded by the mode of spot welding outward.The parallel extensions 602 of described contact elastic arm 601 is shaped in described insulation crust 80 ' away from described abutting pin 603 side, described parallel extensions 603 is unsettled near described abutting pin 603 side, and deformation space is formed between described parallel extensions 603 and described insulation crust 80 ', described abutting pin 603 is formed in the outside bending of the end of described parallel extensions 603, so, described abutting pin 603 is avoided concaving folding and taking described deformation space, for described contact elastic arm 601 provides enough elastic spaces.In described metal isolation, plate 60 ' is grounded by the mode of described abutting pin 603 contacting metal inner casing 12 ' simultaneously, and is soldered to printed circuit board (PCB) without the need to plate 60 ' extraction leg from described metal isolation, and structure is simple, decreases welded complexity.
Refer to shown in Figure 20,21, the embodiment of the present application two is compared to embodiment one, also has the difference of following technology: in described metal isolation, plate 60 ' front-end edge is also provided with some glue injection structures 604, described glue injection structure 604 comprises the less gum-injecting port of front opening 605 and is positioned at appearance glue portion 606 wider on rear side of described gum-injecting port 605, and in described appearance glue portion 606 and described first insulator 50 ', the isolating towards described metal of the second insulator 30 ', the longitudinal channels 53 ', 32 ' of plate 60 ' side is docked.
In the manufacture method of embodiment one, by the second assembly B in step 3, second assembly C integrated injection molding is formed in the process of insulation crust 80 ', gum-injecting port is generally located at described second assembly B, the rear end of the second assembly C, described fluid plastic cement from rear end via described second, 3rd assembly B, the vertical plastic cement runner that in the metal isolation of C, the depressed part 65 of plate 60 both lateral sides is formed enters described by described first, second insulator 50, 30 lateral channel 52 in plate 60 side in the isolation of described metal, 31 with longitudinal channels 53, the 32 longitudinal plastic cement runners formed, subsequently, described fluid plastic cement fills first of plate 60 both sides in the metal isolation of full position, described docking section 81, second terminal group 40, the contact site 41 of 20, inside 21.Because plastic cement runner stroke is long, cause the bad control of injection pressure, cause fluid plastic cement to flow not in place, or injection pressure is excessive and cause the position change of second, third assembly, causes injection moulding bad.And in the present embodiment two, the front end being arranged in described metal isolation plate 60 ' in the front position of described second assembly B, the 3rd assembly C arranges at least one gum-injecting port, make outside fluid plastic cement flows according to the mode in described embodiment one, also make described fluid plastic cement along the gum-injecting port 605 of plate 60 ' front end in the isolation of described metal enter longitudinal runner that described longitudinal channels 32 ', 53 ' forms laggard enter injection mo(u)lding in described transverse flow channels.So, effectively can reduce single from the injection moulding mold pressing needed for the injecting glue of rear end, control the mutual alignment relation between described second assembly B, the 3rd assembly C well, product injection moulding yield is significantly promoted.
Embodiment two except above-mentioned to distinguish with the technology of embodiment one except, other parts are consistent with embodiment one, at this, repeat no more.
The positive anti-plug USB connector of the embodiment of the present application two, when injection mo(u)lding insulation crust 80 ', is entered glue from rear and front end respectively simultaneously, is improved the mobility of fluid plastic cement, alleviate injection moulding mold pressing, make product be not subject to high mold pressing impact and bad.Simultaneously, in described metal isolation, the both sides, rear end of plate 60 ' arrange the contact elastic arm 601 electrically abutted with described inner metal shell 12 ', improve plate 60 ' in the isolation of described metal to need to arrange the defect be welded on described printed circuit board (PCB), make client when designing printed circuit board, have space more flexibly.
