Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other implementation acquired under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
As shown in Figures 1 to 6, the embodiment of the present invention provides a kind of USB interface, including insulation crust 1, the and of inner metal shell 2
Terminal 3.
As shown in figure 1, the relative both ends of insulation crust 1 offer installing port 11 and interface 12 respectively.
As shown in figure 3, terminal 3 includes inserted terminal 31, leads ends 33 and transition part 32, one end connection grafting of transition part 32
End 31, the other end connection leads ends 33 of transition part 32.
As shown in Fig. 4 to Fig. 5, transition part 32 is fixed in inner metal shell 2.
As shown in fig. 6, terminal 3 and inner metal shell 2 are installed in insulation crust 1 by installing port 11, the inserted terminal of terminal 3
31 towards interface 12.
In the embodiment of the present invention, insulation crust 1 and inner metal shell 2 are collectively forming the pedestal of USB interface, wherein, insulation is outer
The installing port 11 of shell 1 is used to install inner metal shell 2 and terminal 3 in insulation crust 1, i.e. inner metal shell 2 and terminal 3 is from installation
Mouth 11 is inserted in insulation crust 1.
The interface 12 of insulation crust 1 is used to be engaged with USB plug, i.e., USB plug is inserted and fixed in interface 12
It is interior, to realize the mechanical connection of USB plug and USB interface and electric connection.
In the embodiment of the present invention, terminal 3 can be used for realizing to terminal charge or for realizing the data between two terminals
Transmission, the wherein inserted terminal 31 of terminal 3 are towards interface 12.
In the embodiment of the present invention, inner metal shell 2 and insulation crust 1 can be two independent parts, be realized by assembling
The connection and fixation of inner metal shell 2 and insulation crust 1.
So, the specific assembly method of the USB interface of the embodiment of the present invention can be：First terminal 3 is fitted into metal
In shell 2, then terminal 3 is set to be fitted into absolutely from installing port 11 together with inner metal shell 2 towards interface 12 inserted terminal 31 of terminal 3
In edge shell 1.
In addition, inner metal shell 2 and insulation crust 1 can also be set integrally by injection molding.So, only need to be by terminal
3 inserted terminal 31 makes terminal 3 be assembled to from installing port 11 in inner metal shell 2 towards interface 12.
In the embodiment of the present invention, insulation crust 1 can be plastic shell, can also be other non-metal shells, in metal
Shell 2 can be iron inner casing.
The USB interface of the embodiment of the present invention includes but is not limited to Type-A USB interfaces, Type-B USB interfaces, Mini-B
USB interface, Micro-B USB interfaces or Micro-AB USB interfaces.For the USB interface of any of the above-described type, it insulate
The shape of shell 1 and inner metal shell 2 makees adaptive change, on the other hand, the embodiment of the present invention and being not construed as limiting.
By taking Micro-B USB interfaces more conventional at present as an example, the shape of the interface 12 of insulation crust 1 should be with
The profile of Micro-B USB plugs is adapted, the shape as shown in Fig. 6；In addition, inner metal shell 2 is except including for holding
Put and outside the inner casing body 21 of the transition part 23 of fixing terminal 3, should also include prolonging from inner casing body 21 to the direction of interface 12
The hyoplastron 22 stretched, hook hole 221 should be also opened up on the hyoplastron 22, for mounting the metal hanger on Micro-B USB plugs,
As shown in Figure 2., can be by the hyoplastron 22 in Fig. 2 if the USB interface of the embodiment of the present invention is adapted to Micro-AB USB interfaces
Removed from inner casing body 21.
It is well known that the Net long wave radiation of antenna is realized by antenna structure part, it is undesirable to which the device of surrounding participates in radiation.If
Peripheral devices are too near with antenna structure part, larger coupling can be produced with antenna structure part, so as to reduce the efficiency of antenna.
If the shell of USB interface is metal shell, the inevitable all metals of its interface, then USB interface is either
No electric connection, its interface can have an impact to the performance of additional antenna.
And in the embodiment of the present invention, as shown in fig. 6, due at interface 12 at least three faces be insulating materials, can drop
Coupling between undershoot interface 12 and antenna, so as to reduce interference of the USB interface to aerial signal.In addition, the present invention is implemented
In example, the socket base of USB socket is collectively forming using insulation crust 1 and inner metal shell 2, it is possible to increase socket base structure
Stability.
Optionally, as shown in Fig. 1, Fig. 7 to Figure 13, USB interface also includes grab shell fragment 4, and grab shell fragment 4 includes two bullets
Property arm 41, two elastic arms 41 are fixed on inner metal shell 2, and are respectively arranged at the both sides of inserted terminal 31.
In embodiment of the present invention, USB interface can also include grab shell fragment 4, and two elastic arms 41 of grab shell fragment 4 are used
In USB plug insert USB interface when, USB plug is clamped, contact engaging and separating force is provided for USB plug, prevent USB plug from
Exited easily in USB interface, as shown in figure 13.
Optionally, as shown in Figs. 8 to 11, grab shell fragment 4 also includes the linkage section 42 of two elastic arms 41 of connection, connection
Be provided with section 42 it is at least one move close to somebody's ear 43, each move close to somebody's ear 43 to be welded on inner metal shell 2.
In embodiment of the present invention, grab shell fragment 4 also includes the linkage section 42 of two elastic arms 41 of connection, so, grab
Shell fragment 4 can form an entirety.Furthermore it is possible to set on linkage section 42 it is at least one move close to somebody's ear 43, will move close to somebody's ear 43 to be welded in
On inner metal shell 2, to realize being fixedly connected for grab shell fragment 4 and inner metal shell 2.
For the USB interface including grab shell fragment 4, overall assembly method should be that terminal 3 first is assemblied in into gold
Belong in inner casing 2, then grab shell fragment 4 43 is welded on inner metal shell 2 by moving close to somebody's ear, now, terminal 3, inner metal shell 2 and grab
The connection of shell fragment 4 is integral, and finally, terminal 3, inner metal shell 2 and grab shell fragment is integrally inserted in insulation crust 1, USB interface
Assembling i.e. complete.
Wherein, 43 modes that can be as shown in Figure 7 to 9 of moving close to somebody's ear are set, i.e., setting two on linkage section 42 moves close to somebody's ear 43, and
Two 43 both sides for being respectively arranged at linkage section 42 of moving close to somebody's ear.
Move close to somebody's ear 43 can also mode as shown in figure 11 set, i.e., setting one on linkage section 42 moves close to somebody's ear 43, and this moves close to somebody's ear 43
It is arranged at the middle part of linkage section 42.
In both the above set-up mode, the mode preferably shown in Fig. 7 to Fig. 9.Because if 43 are moved close to somebody's ear in linkage section 42
Centre position, then the pad between 43 and inner metal shell 2 of moving close to somebody's ear also is located at the centre position of inner metal shell 2, so, both sides
Elastic arm 41 it is long apart from the distance of pad, the conducting spacing of its elastic arm 41 and inner metal shell 2 is longer.If move close to somebody's ear
43 in the both sides of linkage section 42, then can shorten the conducting spacing between elastic arm 41 and inner metal shell 2.
