Description

The socket connection part of mobile communication terminal

Technical field

The present invention relates to the socket connection part of mobile communication terminal, the swivelling cover that is connected in spring covers the insertion mouth that socket is installed, and makes the installation of socket and pulls up more convenient.

Background technology

Fig. 1 is the oblique view of the socket connection part of mobile communication terminal in the past, and Fig. 2 is the sectional oblique drawing that shows the socket connection part shape.

As shown in the figure, mobile communication terminal 10 had also had the data transmit-receive function of multiple mode recently except simple telephony feature in the past.In terminal 10 in the past, the data transmit-receive function is not to be defined in wireless mode, can be undertaken by cable 20 yet.

In the past, form the socket connection part 11 that the 1st socket 12 has been installed in mobile communication terminal 10 1 sides, in the 2nd socket 21 that inserts the 1st socket 12 and combination, connecting external cable 20.

Socket connection part 11 comprises following several sections: insert mouth 13, it inserts for the 2nd socket 21 that is connecting cable 20; The 1st socket 12, it is formed with conduction and is connected in a plurality of terminals that socket inserts the terminal PC B (Printed circuit board) of mouthful 13 inboards on the two sides; Rubber stopper 15, it is used to open closes socket and inserts mouthfuls 13.

When using in the past terminal 10, in order to charge or to carry out data communication, need insert the 1st socket 12 to the 2nd socket 21 with the outside, make cable 20 and terminal system realize conducting electricity and be connected.In this case, pulling up rubber stopper 15 back insertion the 2nd sockets 21 that are inserted in the insertion mouth 13 gets final product.

And, after using corresponding function, the 2nd socket 21 is extracted from inserting mouth 13, in inserting mouth 13, insert rubber stopper 15 again, prevent to be subjected to outside pollution and damage.

But but there are the following problems always to have the structure of socket connection part in the past that as above constitutes.

In the past, when inserting socket 21, need extract rubber stopper 15 backs and insert, and after pulling up socket 21, again rubber stopper 15 was inserted into and insert in the mouth 13.Therefore exist because of plug rubber stopper 15 to the user with inconvenience, and rubber stopper 15 also may take place in this course lose.

Summary of the invention

The object of the present invention is to provide a kind of socket mounting structure of mobile communication terminal, the swivelling cover that is connected in spring covers the insertion mouth that socket is installed, can when mounting receptacle, rotate and enter the inboard, when extracting socket, the sealing socket inserts mouth automatically under the effect of spring reducing power.

For achieving the above object, the feature of the socket connection part of mobile communication terminal of the present invention is to comprise following several sections: the 1st socket, and it is installed on above-mentioned terminal shell inside, is connected with system's conduction of terminal; Insert mouth, it forms on above-mentioned housing, and the 2nd socket that is connecting the external data cable can be combined with above-mentioned the 1st socket; Door, it is inboard and rotatable that it is installed on above-mentioned insertion mouth, opens, closes above-mentioned insertion mouth selectively by rotation; Spring, it is installed on above-mentioned slotting inlet side, is used to make above-mentioned door to keep the state of the above-mentioned insertion mouth of sealing.

Another feature of the present invention is: above-mentioned spring is that an end is fixed in the torsion spring that above-mentioned door medial surface, the other end are fixedly installed in above-mentioned housing inboard.

Another feature of the present invention is: protrude at the two ends of door and be provided with rotating dog, above-mentioned each rotating dog is inserted in the hole that above-mentioned insertion mouth inner top side forms, and when inserting above-mentioned the 2nd socket, above-mentioned door rotates upward.

In the present invention, by as above structure, when being in socket and inserting state, the door rotation that socket inserts mouthful, be close proximity to insert mouthful above; When socket did not insert, under the elastic restoration power effect of spring, the door rotation also closed the insertion mouth, and the socket that forms on the protection housing is not subjected to external contamination, can also improve the facility of plug socket simultaneously.

With reference to the accompanying drawings, describe the formation of the useful embodiment of socket connection part in detail with the mobile communication terminal of the present invention that as above constitutes.

Embodiment

Fig. 3 is the sectional view of the socket connection part of present embodiment, and Fig. 4 is the exploded perspective view of mobile communication terminal socket connection part of the present invention, and Fig. 5 a and Fig. 5 b are the sectional views that shows its user mode.

As shown in the figure,, be formed with, in order to realize the socket connection part 31 that conduction connects in conjunction with the 1st, the

2nd socket

35,41 in mobile communication terminal 30 1 sides that the present embodiment socket has been installed for charging or the data communication that realizes terminal.。

The 1st socket 35 that is connected with the PCB33 conduction is installed on the housing of terminal 30, and the 2nd socket 41 that is connecting external data cable 40 is connected and installed in the 1st socket 35 selectively.

The 1st socket 35 that is built in present embodiment terminal 30 housings is for tabular, and the PCB33 that is installed with on the two sides by terminal system prolongs a plurality of terminals that form.

On the place ahead shell 32 corresponding, be formed for inserting the insertion mouth 37 of the 2nd socket 41 that is connecting external cable 40 with the 1st socket 35.

And, door 38 in insertion mouth 37 installed inside of present embodiment, door 38 can rotate, and prolongs in the both sides, upper end of door 38 and forms the rotating dog 38a that makes door 38 rotations.And, have rotation projection 39 in insertion mouth 37 upper ends of present embodiment, rotate formation rotating hole 39a on the projection 39, insert also rotatable for above-mentioned rotating dog 38a.

In the present embodiment, insert mouthful 37 outsides if door 38 is pulled out, then can produce the slit, foreign matter will enter inside, causes the 1st socket 35 to be polluted or damages.The door 38 of present embodiment is preferably with and can covers the whole area that inserts mouth 37 from the inboard.

In the present embodiment, under the state that the 2nd socket 41 does not insert, can make door 38 maintenances close the state that inserts mouth 37, on the inboard shell 32 that inserts mouth 37 spring 50 is installed, spring 50 provides the elastic restoration power of the door 38 of direction promotion laterally.

In the present embodiment, spring 50 is that an end is fixed in the torsion spring that the shell 32, the other end that insert mouthful 37 tops are fixedly installed in door 38 medial surfaces.

The following describes the effect of the socket connection part of mobile communication terminal with the embodiment of the invention that as above constitutes.

In the time will carrying out data communication to the socket connection part 31 that external cable 40 is connected to the terminal 30 of present embodiment, the 2nd socket 41 is inserted into inserts mouthful 37 uses and get final product.

When insertion the 2nd socket 41, though the elastic restoration masterpiece of oriented lateral direction effect is used for door 38, under the effect of the 2nd socket 41 motive forces, door 38 rotations are moved to inserting mouthful 37 tops, insert mouth and open.So the 2nd socket 41 can be incorporated into the 1st socket 35.

On the contrary, when not wanting to connect external cable 40 and use terminals 30, extract and get final product being inserted in the 2nd socket 41 in the socket connection part 31.In this case, under the spring 50 elastic restoration power effects that promote door 38, the below is also reduced in door 38 rotations, closes and inserts mouth 37.

Interest field of the present invention is not only to be defined in the foregoing description, but by claims decisions, be included in certainly with claims in various distortion and the transformation carried out in the same range as of specified particular.
