Fig. 2 is the schematic top plan view of Fig. 1 structures；

Fig. 3 is the enlarged diagram of part A in Fig. 1.

Specific embodiment

To make those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings and specific implementation Mode is described in further detail to a kind of mobile terminal provided by the present invention.

Refering to Fig. 1, mobile terminal embodiment of the present invention includes：It is shell 11, the wiring board 12 being arranged inside shell 11, solid The USB socket 13 being scheduled on wiring board 12, the conversion head 14 for being plugged in USB socket 13.

Wherein, shell 11 includes center 111.

Refering to Fig. 2, wiring board 12 is provided with the limited post 122 of pad 121 and first, it is preferred that the number of the first limited post 122 Measure is two.

USB socket 13 is fixed in assist side 12 by way of welding.

Specifically, USB socket 13 is welded on wiring board 12 by the pad 121 on wiring board 12.

Wherein, USB socket 13 is USB female seats.

The grafting of conversion head 14 and USB socket 13, and be supported on wiring board 12, for connecting external USB plug, and transfer To USB socket 13.

Specifically, conversion head 14 is male and female conversion head, including conversion head male seat 141 and conversion head female seat 142, conversion head are public Seat 141 and the grafting of USB socket 13, with USB socket 13 of transferring；Conversion head female seat 142 be used for connect external USB plug, for Family uses.

Further, the outer end of conversion head 14 is arranged to concordant with the outward flange of wiring board 12 or is arranged at wiring board 12 Inside.

Specifically, after USB socket 13 is welded on wiring board 12, the distance at USB socket 13 and wiring board edge can make After obtaining the insertion USB socket 13 of conversion head 14, the outer end of conversion head 14 will not stretch out the edge of wiring board 12.

Additionally, being additionally provided with spacing preiection 143 on conversion head 14, it is preferred that the quantity of spacing preiection 143 is two, respectively It is arranged at the opposition both sides of the non-grafting USB socket 13 of conversion head 12；

Specifically, spacing preiection 143 is arranged at the both sides of conversion head female seat 142, and the first limited post 122 on wiring board 12 The direction of insertion along conversion head 14 relative to USB socket 13 is arranged near the side of USB socket 13 so that the first limited post 122 coordinate to limit insert the distance of the conversion head 14 relative to USB socket 13, two the first limited posts 122 with spacing preiection 143 Coordinate with two spacing preiections 143 respectively.

As shown in Fig. 2 when conversion head 14 inserts USB socket 13 to the right, the first limited post 122 is arranged at conversion head 14 and inserts Enter on the path of USB socket 13, and can be contacted with spacing preiection 143 so that when the right side of spacing preiection 143 on conversion head 14 When touching the first limited post 122, the limitation conversion head 14 of the first limited post 122 continues to insert USB socket 13 to the right.

Fig. 1 is further regarded to, mobile terminal of the present invention also includes elastic pressing piece 15, and elastic pressing piece 15 is arranged at switching First 14 away from wiring board 12 side.

Specifically, elastic pressing piece 15 is attached at the top of conversion head 14, will by the center 111 of the top of elastic pressing piece 15 Conversion head 14 is pressed on wiring board 12, is moved up perpendicular to the side of wiring board 12 with limiting conversion head 14.

Wherein, elastic pressing piece 15 can be the flexible gasket of including but not limited to rubber blanket.

Further, the second limited post 151, the second limited post 151 and spacing preiection are additionally provided with elastic pressing piece 15 143 coordinate, to prevent conversion head 14 from being released from USB socket 13；Preferably, the quantity of the second limited post 151 be two, respectively with Two spacing preiections 143 coordinate.

Specifically, the second limited post 151 is arranged at spacing preiection along conversion head 14 relative to the direction of insertion of USB socket 13 143 away from USB socket 13 side, i.e., the left side of spacing preiection 143 as shown in Figure 1；When conversion head 14 inserts USB socket 13, and coordinated by the first limited post 122 and spacing preiection 143 when continuing into USB socket 13 to the right to limit conversion head 14, the Two limited posts 151 touch spacing preiection 143 and are moved to the left with limiting conversion head 14, and then prevent conversion head 14 from USB socket 13 Release.

Wherein, as shown in figure 3, along conversion head 14 relative to USB socket between the second limited post 151 and spacing preiection 143 13 direction of insertion T spaced a predetermined distance so that when elastic pressing piece 15 pushes down conversion head 14, spacing preiection 143 will not withstand Second limited post 151.

Specifically, the second limited post 151 and the left side predeterminable range T of spacing preiection 143, are 0.1mm-0.3mm apart from T；It is excellent Choosing, be 0.25mm apart from T.

In sum, when mounted, USB socket 13 is welded on wiring board 12, then conversion head 14 is passed through into conversion head The grafting USB socket 13 of male seat 141, until the spacing preiection 143 on conversion head 14 contacted with the first limited post 122 with limit its after Continuous insertion USB socket 13, and then wiring board 12 is installed and in housing 11, makes center 111 by elastic pressing piece 15 and second Limited post 151 presses on wiring board 12 conversion head 14, and limitation conversion head 14 is moved up perpendicular to the side of wiring board 12 And prevent conversion head 14 from being released from USB socket 13, now, conversion head 14 is relatively fixed with wiring board 12 and shell 11, conversion head Female seat 142 can connect external USB plug, with for users to use.

Prior art is different from, the present invention, should by setting a conversion head for being plugged in USB socket inside terminal enclosure The mode that conversion head is connected with external USB plug so that user when in use USB interface when, it is only necessary to by external USB plug with Conversion head is connected, and when user exerts oneself excessive, only results in conversion head damage, will not be damaged USB socket and be used it Lifetime, and it is relatively fixed the conversion head and wiring board by the first limited post, the second limited post and elastic pressing piece, make Proper conversion head is damaged when needing repairing, it is only necessary to open shell, you can conversion head is extracted from USB socket, simple to operate, Convenient maintenance.

Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills Art field, is included within the scope of the present invention.
