Specific embodiment

To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.

It please refers to shown in Fig. 1, Fig. 2, the anti-excessively slotting positive anti-plug USB socket of the application includes plug connector A, is sheathed on described insert The metal shell 20 that inner metal shell 10 and cladding outside fitting A are welded to outside the inner metal shell 10.

Please continue to refer to shown in Fig. 3 to Fig. 6, the plug connector A includes plate 60 in shielding, be placed in plate 60 in the shielding First, second terminal group 40,50 of upper and lower two sides and plate 60, the first, second terminal group 40,50 in the shielding are combined into one The insulating body 70 of body.

Emphasis is as shown in fig.5, plate 60 includes main part 61, is formed in 61 both lateral sides of main part in the shielding The card slot 62 of front end, the material strip interconnecting piece 63 for being formed in 61 both lateral sides of main part protrude from the main part 61 laterally The blocking part 64 of two sides rear end and the weld part 65 extended to form from the main part 61.The material strip interconnecting piece 63 is located at described Between card slot 62 and the blocking part 64；Width between two blocking parts 64 is greater than the width between two card slots 62.

Emphasis as shown in fig.6, the first end subgroup 40 include holding parts 41, from before the holding parts 41 to extend shape At contact portion 43 and from the leg 42 of the rearwardly extending formation of the holding parts 41.The contact portion 43 includes and banjo end The functional areas 431 and nonfunctional area 432 of son contact.In injection molding, the surface of the functional areas 431 cannot generate excessive glue, Otherwise it will lead to contact performance problem.To transmit high-frequency signal, the contact portion 43 can be arranged abnormally-structured 433, i.e., the described function The width in energy area 341 is greater than the width of the nonfunctional area 432, and termination width is caused to narrow or broaden.The second end subgroup 50 is consistent with the first end subgroup 40, and details are not described herein again.Herein, described abnormally-structured 433 are defined positioned at described non-functional At zone position.

Refering to shown in Fig. 3, Fig. 4, the first end subgroup 40 is integrated simultaneously emphasis with 60 integrated injection molding of plate in the shielding Form first insulator 80；50 integrated injection molding of second end subgroup is integrated and forms second insulator 90.Described first absolutely Edge body 80 be superimposed with the second insulator 90 after again injection molding be formed as one the insulating body 70.Described first, Second insulator 80,90 fills the gap between first, second terminal group 40,50, in first, second terminal group First plastic block on surface and 40,50 flush of the first, second terminal group is formed between 40,50 nonfunctional area 432 801；The second plastic block 802 for being lower than 40,50 surface of the first, second terminal group is formed between the functional areas 431；Institute The surface for stating the first plastic block 801 is higher than the height of second plastic block 802, and in first plastic block 801 and second Stage portion 803 is formed between plastic block 802.In this way, can be when forming the insulating body 70, without closing first, second Abnormally-structured 433 position of terminal 40,50, it is only necessary to close its whole upper surface, avoid abnormally-structured 433 closing difficult and The problem of causing 431 excessive glue of functional areas, and then influence properties of product.

The insulating body 70 includes base portion 71, from before the base portion 71 to the docking tongue 72 extended to form and takes shape in The fixed block 73 of 71 rear end of base portion, the transverse width of the fixed block 73 is greater than the transverse width of the base portion 71, described The lateral outer ends of fixed block 73 include the ear 74 equipped with perforation 75.The width of the base portion 71 is greater than the docking tongue 72 Width.The functional areas 431 of the contact portion 43 of first, second terminal group 40,50 are exposed to the upper and lower of the docking tongue 72 Surface.

The blocking part 64 of plate 60 is exposed to the base portion 71 and is located at outside lateral the two of the docking tongue 72 in the shielding The shell that banjo is kept out at side position, prevents banjo to be excessively inserting.

Emphasis refering to fig. 1, shown in Fig. 2, the inner metal shell 10 includes cylindrical body 11 and being stamped and formed out in the tubular In main body 11 and extend inwardly to the protrusion 12 on 70 base portion of insulating body, 71 front end face.The protrusion 12 is for hindering The only excessive insertion of banjo.The cylindrical body 11 has been stamped and formed out note at 12 position of protrusion and has been covered with waterproof membrane 30 To realize the waterproof of punching hole.

The metal shell 20 includes being respectively welded in the first, second metal shell of 11 top and bottom of cylindrical body 21,22.First metal shell 21 include the first matrix part 211, be opened on first matrix part 211 and it is corresponding described in Aperture 212 at 12 position of protrusion is formed in 211 transverse edge of the first matrix part and the first sticking part that bending is formed 213 and the covering portion 214 that is extended rearwardly to form from first sticking part 213.The covering portion 214 includes from first patch Conjunction portion 213 extends back and the first covering portion 2141 of parallel first sticking part 213, from first covering portion 2141 The second covering portion 2142 that outside vertical bending extends to form and extend from the vertical bending of second covering portion 2142 and with institute State the parallel third covering portion 2143 of the first covering portion 2141.The covering portion 214 coats the fixed block of the insulating body 70 73 ear.First, second covering portion 2141,2142 is additionally provided with through-hole corresponding with the aperture 75 in the ear 74 2144。

Second metal shell 22 includes the second matrix part 221, is formed in 221 transverse edge of the second matrix part simultaneously The second sticking part 223 be bonded with first sticking part 213 that bending is formed, from 221 rear end of the second matrix part transverse direction Two sides bending extends and passes through the insertion section 224 of the aperture 75 and through-hole 2144.It is coated as a result, by the covering portion 214 The ear 74, and the covering portion 214 and the ear 74 are passed through by the insertion section 224 and realize metal shell 22 and absolutely Stability between edge ontology 70.

The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal Replacement, improvement etc., should be included within the scope of the claims of this application.
