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.

Referring to FIG. 1 to 4, the positive anti-plug USB socket of the application includes middle plate 40, is located at about the 40 middle plate First, second terminal group 50,70 of two sides, take shape in first insulator 60 in the first end subgroup 50, take shape in it is described First, second insulator 60,80 is taken shape in integrated third insulator by second insulator 80 in second end subgroup 70 30 and the metal shell 10,20 that is sheathed on outside the third insulator 30.

The metal shell includes inner housing 10 and the outer housing 20 that is coated on outside the inner housing 10, the inner housing 10 Including cylindrical body part 11,20 baseplate part 21 of outer housing, the weldering extended to form from the 21 both lateral sides bending of baseplate part Socket part 22, the clasp piece 23 being held on the third insulator 30 from 21 bending of baseplate part and from before the baseplate part 21 Side bending extends to the welding piece 24 on the cylindrical body part 11 of the inner housing 10, and the welding piece 24 is extended with and the cylinder The covering part 25 that shape main part 11 is bonded, the covering part 25 are welded in one by spot welding and the cylindrical body part 11.

The third insulator 30 include base portion 31 and from before the base portion 31 to the docking tongue 32 extended to form.It is described First second end subgroup 50,70 includes the contact portion (not labeled) for being exposed to docking 32 upper and lower surface of tongue, described in What contact portion extended rearwardly to form be separately formed in first, second insulator 60,80 holding parts (not labeled) and from The holding parts extend extraneous leg (not labeled).The holding parts be included in plug orientation extension horizontal part and from The vertical portion that the vertical bending of the horizontal part extends to form.

With continued reference to shown in Fig. 5, the first insulator 60 includes the first matrix part 61 and from first matrix part 61 Extend vertically the first vertical wall 62 to be formed.The horizontal parts of the holding parts of the first end subgroup 50 and vertical portion respectively one at Type is in first matrix part 61 and first vertical wall 62.The second insulator 80 is including the second matrix part 81 and certainly Second matrix part 81 extends vertically the second vertical wall 82 to be formed.The horizontal part of the holding parts of the second end subgroup 60 with Vertical portion is shaped in respectively in second matrix part 81 and second vertical wall 82.

First matrix part, the 61 front end both lateral sides are equipped with buckle step 63, the buckle step 63 towards described second 80 side of insulator is equipped with guiding face 631, and the buckle step 63 is equipped with buckle platform far from 80 side of second insulator 632, the surface of the buckle platform 632 is lower than the surface of first matrix part 61.The medial surface of first vertical wall 62 It outwardly protrudes to form boss 65, the medial surface of first vertical wall 62 is also recessed inwardly to form slot structure 64, the boss 65 Area be less than first vertical wall 62 area half, it is optimal be one third.The both lateral sides of the boss 65 Positioning region 66 is formed, the surface of the positioning region 66 is lower than the surface of the boss 65.

With continued reference to shown in Fig. 6, the trailing flank 821 of the second vertical wall 82 of the second insulator 80 is horizontal smooth The both lateral sides in face, the trailing flank 821 are equipped with protrusion 822.Second matrix part 81 corresponding described 63, buckle step The place of setting extends to form button hook 84.

The middle plate 40 includes main part 41, several location holes 43 for being opened on the main part 41 and from the main body The band hangnail hook 42 that the upward bending in 41 rear end of portion extends to form.First matrix part 61 corresponding described band hangnail hook 42 It sets place and is equipped with card slot 67, protrusion is formed with positioning column 86 at corresponding 43 position of location hole of second matrix part 81.

In 30 injection molding process of third insulator, first the band hangnail hook 42 of the middle plate 40 is caught in described So that the middle plate 40 is incorporated into 60 lower section of first insulator in card slot 67, then by the button hook 84 of the second insulator 80 Be held on the buckle step 63 of the first insulator 60 so that first, second insulator 60,80 and in hardened be combined into One, meanwhile, the positioning column 86 of the second insulator 80 is positioned in the location hole 43 of the middle plate 40.At this point, described The boss 65 of 62 medial surface of the first vertical wall of one insulator 60 is resisted against the second vertical wall 82 of the second insulator 80 On lateral surface 821, when third time is molded, the boss 65 can be born from the second insulator 80 in high speed plastic cement fluid Strength under impact makes the second insulator 80 not generate displacement to avoid terminal contact portion displacement.

Meanwhile the locating recess 66 of 65 periphery of boss and the protrusion 822 cooperation position described first, second The lateral position of insulator 60,80.Slot structure 64 outside the boss 65 then makes first, second insulator full of plastic cement 60,80 combinations are closer.

Boss 65 is arranged by 62 medial surface of the first vertical wall in first insulator 60 in the positive anti-plug USB socket of the application, The lateral surface that the second vertical wall 82 of the second insulator 80 is abutted using the boss 65, avoids first vertical wall 62 Medial surface integrally abuts 82 lateral surface of the second vertical wall and causes to influence the first, second insulator 60,80 because of flatness tolerance Between relative position；Meanwhile the boss 65 can bear the impact strength from high speed plastic cement fluid again, and in boss 65 Outside is arranged for filling the slot structure 64 of plastic cement with closer the first, second insulator of combination 60,80.

The positive anti-plug USB socket of the application on the first matrix part 61 of the first insulator 60 by being arranged buckle step 63, the button hook being held on the buckle step 63 is extended to form at the corresponding buckle step 63 of the second insulator 80 84, it combines first, second insulator 60,80 between each other more closely in third time injection molding, avoids moving Position.
