Embodiment

The double-deck connector of the USB of this embodiment comprises as shown in Figure 1: the shell 1 of metal material, tail-hood 2, insulating body 3, eight conducting terminals 4 and middle intermediate plates 5.The double-deck connector of the USB of this embodiment is double-deck connector, and described 8 conducting terminals 4 are divided into two groups up and down, and each conducting end is from 4 all by insulating body 3 location of plastic material injection mo(u)lding, and it is interior and fix to fill in shell 1 then together.The socket of insulating body 3 front ends is divided into two identical sockets up and down by intermediate plate 5 in described, can insert a USB male in each socket, and makes and insert USB male four the conducting terminals 4 corresponding contacts corresponding with it in it and electrically connect.Tail-hood 2 bending bonnets are closed in insulating body 3 and conducting terminal 4 in the shell 1 in shell 1 rear end, thereby form the double-deck connector of complete USB.

One of special feature of this embodiment is, tail-hood 2 and shell 1 one, and Just because of this, tail-hood 2 covers and is difficult for pine moves back after shell 1 rear end.And as shown in Figure 2, offer two on the connecting line of tail-hood 2 and shell 1 and pre-fold groove 21.The double-deck connector assembling of USB need make tail-hood 2 close shell 1 rear end 1 bending of tail-hood 2 opposite shell.These two pre-fold groove 21 can the accurate in locating crease line, can not produce the phenomenon of crease line bending when guaranteeing tail-hood 2 bendings, and opposite shell 1 bending easily.

As depicted in figs. 1 and 2, tail-hood 2 both sides respectively are provided with a clamping ear 22, and offer blocked hole 23 on the clamping ear 22.This clamping ear 22 is vertical with tail-hood 2, and when tail-hood 2 was placed on shell 1 rear end, clamping ear 22 inserted in the shell 1, and the two side of close shell 1.And the position of corresponding blocked hole 23 is provided with shell button point 14 to inner process on the described sidewall of shell 1, tail-hood 2 bendings and when being placed on shell 1 rear end, and described shell button point 14 snaps in the blocked hole 23, thereby stops tail-hood 2 to be deviate from from the rear end of shell 1.

Can see all that by Fig. 1 and Fig. 2 respectively be provided with two shell cards 11 on shell 1 side walls, the two ends of shell card 11 all are connected with shell 1, and its inwardly bending of middle part.Produce contact engaging and separating force with USB male Elastic Contact when shell card 11 is used for the double-deck connector of USB and inserts the USB male, and, guarantee that easily this contact engaging and separating force remains in the claimed range of USB consortium specification because this shell card 11 and shell 1 are one.

Can also see in conjunction with Fig. 2 by Fig. 1, respectively be provided with two grabs 12 on the upper and lower surface of shell 1, and all be provided with ribs 13 on each grab 12.This ribs 13 increases the intensity of grab 12, thereby not yielding, and can also play the effect that increases contact engaging and separating force.Can be seen also that by Fig. 2 tail-hood 2 is provided with two convex epireliefs 24 to outer lug, this convex epirelief 24 extrudes when shell 1 and tail-hood 2 are integrally formed together, its role is to effectively to prevent that the outer surface of tail-hood 2 from scratching because of friction.In addition, the upper surface of shell 1 also is provided with a convex epirelief 15 based on same reason.

The concrete structure of insulating body 3 as shown in Figure 3, because its effect mainly is the two groups of conducting terminals 4 in location, produce to shrink in order to prevent that the plastic cement wall thickness is blocked up, simultaneously also in order to reduce the consumption of plastic material, insulating body 3 is hollowed out as much as possible and is formed frame structure.For each conducting terminal 4, on the insulating body 3 corresponding setting three location screens, be respectively the prelocalization screens 31 shown in Fig. 3, middle location screens 32 and back location screens 33.Situation after the assembling as shown in Figure 4 owing to increased middle location screens 32 compared to existing technology, it can carry out more accurate localization to the long end afterbody of conducting terminal 4.Also be provided with locating groove post 34 between per two adjacent conductive terminals 4.The width of locating groove post 34 is set to wide as far as possible, fills the gap between full two conducting terminals 4 basically, is fractureed in the process of assembling to prevent locating groove post 34 as much as possible.In addition, can also see that back location screens 33 comprises two sections draw-in grooves not of uniform size, is respectively epimere draw-in groove 331 and hypomere draw-in groove 332 by Fig. 5.Epimere draw-in groove 331 broads, broad position tight fit plays fixation when conducting terminal 4 is pressed into and on the conducting terminal 4.Hypomere draw-in groove 332 is narrower, equates with the width of conducting terminal 4 basically or slightly is wider than conducting terminal, conducting terminal 4 is played the effect of location.

In intermediate plate 5 structure as shown in Figure 6, it roughly becomes " U " shape structure, has certain elasticity.It is used to be clipped in insulating body 3, and insulating body 3 front ends are used to insert the space dimidiation of USB male, makes the double-deck connector of USB can insert two USB males.Middle as seen from Figure 6 intermediate plate 5 upper and lower surfaces respectively are provided with two shell fragments 51, and it is used to cooperate the grab 12 on the shell 1, and the USB male of inserting is played guide function and produces suitable contact engaging and separating force.The end of middle in addition intermediate plate 5 upper and lower surfaces also respectively is provided with two positioning convex points 52, can accurately locate after intermediate plate 5 is pressed into and clamps insulating body 3 in making, and be not easy to rock or deviate from because of the plug of USB male.The end of middle as seen from Figure 7 intermediate plate 5 upper and lower surfaces also is provided with chamfering 53, thereby the end of middle intermediate plate 5 is more smooth and easy and easy to assembly when being pressed on the insulating body 3 corresponding hole, and can be insulating body 3 scratches.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
