Andpower subsystem 190 for example comprises rechargeable battery and is connected so that battery charge detachablely.

Fig. 3 is the back stereogram of an example of the communication terminal shown in Fig. 2 according to an embodiment of the invention.

With reference to Fig. 3, the second camera model 121-2 can be set to the back of thesecond back cover 100B-2 extraly.The second camera model 121-2 has the basic shooting direction relative with the shooting direction of first camera model (121-1: with reference to Fig. 1) and can have and the first camera model pixels with different.

For example, the first camera model 121-1 has the low pixel that in video communication, enough captured user's face is sent to the communication party.The second camera model 121-2 preferably includes high pixel, because captured theme generally is not to be sent out immediately.Other distortion also is possible.

Photoflash lamp 121-3 and mirror 121-4 can be set near the second camera model 121-2 extraly.When the user used the second camera model 121-2 photographed subject, photoflash lamp 121-3 can be configured to this theme flash of light.Mirror 121-4 makes the user when attempting to autodyne, see face of oneself etc.

The second audio frequency output module 152-2 can be set to thesecond back cover 100B-2 extraly.

The second audio frequency output module 152-2 can realize stereo function and can in speakerphone mode, be used to conversation with the first audio frequency output module (for example, the element 152-1 among Fig. 2) together.

Make the first andsecond body 100A and 100B are located on thefirst back cover 100A-2 offirst housing 100A by the part of the slidingblock 100C that slidably assembles.And other part of slidingblock 100C is located on the secondfore shell 100B-1 that shown in figure, does not expose ofsecond housing 100B.

In above description, the second camera model 121-2 etc. is set on thesecond housing 100B, but the present invention not limit by its.For example, being located among element 111-1,121-2,121-3 and the 152-2 on thesecond back cover 100B-2 at least one such as second camera model 121-2 etc. also can be located on thefirst housing 100A especially on thefirst back cover 100A-2.

If (all) elements of being located at thefirst back cover 100A-2 are protected in and close in the configuration is favourable so.In addition, even without the second camera model 121-2 is provided in addition, the first camera model 121-1 also can be set as with being rotated and can on the shooting direction of the second camera model 121-2, take.

The PCB (printed circuit board (PCB)) that wherein is useful on the various chips of each function that realizes communication terminal is fixed or is installed in the communication terminal 100.And PCB can be located within the back of the body lid.

Data are from being provided such aswireless communication unit 110 wireless communication units such as grade.And PCB handles these data and subsequently dateout is sent to the various modules such as output unit 150 output units such as grade.So power subsystem should be provided for the required electric current of deal with data.The wireless communication unit that separates each other, power subsystem and PCB connect through coaxial cable.

Fig. 4 is the stereogram of an example that is set at the coaxial cable of communication terminal according to an embodiment of the invention, and Fig. 5 is the diagrammatic sketch of an example of the inside of communication terminal according to an embodiment of the invention.

With reference to Fig. 4 and Fig. 5,first lead 12 is set at the center (or core) of coaxial cable 10.First lead 12 is formed by the metal with good electrical conductance.Preferably,first lead 12 is formed by copper.And 12 in first lead transports such as action of electric signals such as RF signals.In addition,first lead 12 is connected to first andsecond coupling parts 35 and 45 as illustrated in fig. 5.

Inner insulatinglayer 14 is located at the outside of first lead 12.Inner insulating layer 14 is set up the excircle that closesfirst lead 12 in order to bag.Inner insulating layer 14 is formed by the material that is used to insulate such as resin etc.Inner insulatinglayer 14 makesfirst lead 14 and 16 insulation of second lead to avoid between them, producing electrical interference.So, can ignore external disturbance or noise and transmit signal relatively stablely.

Second lead 16 is located at the outside of inner insulating layer 14.Second lead 16 is configured to bag and closes inner insulating layer 14.Preferably,second lead 16 can be configured to netted pattern.

Second lead 16 is formed by the material that has good electrical conductance such as copper, aluminium etc.

Second lead 16 be electrical conductance and can be used as the path of transporting the signal of telecommunication.Therefore, because first and second leads 12 and 16 that are located in the coaxial cable can transmit two kinds of signals of telecommunication simultaneously betweenwireless communication unit 110 andPCB parts 28.

In addition,second lead 16 is connected to grounded parts and plays the effect that prevents that outside introducing electric wave or noise are introduced to the screen infirst lead 12.

External insulation layer 18 is located at the outside of second lead 16.External insulation layer 18 is by forming with inner insulatinglayer 14 the same good resins etc.External insulation layer 18 blocksfirst lead 12, inner insulatinglayer 14 andsecond lead 16 in thecoaxial cable 10 so that they are protected with external environment condition.

In a plurality of throughholes 20 one can be configured to inner insulatinglayer 14 axially on penetrate.Each throughhole 20 usefulness air fills up the effect that prevents the wave interference betweenfirst lead 12 andsecond lead 16 to play.

Particularly, secondly the wave interference betweenfirst lead 12 andsecond lead 16 prevents through throughhole 20 on mainly preventing through inner insulatinglayer 14.

Like what mention in the above description, ground connection is accomplished throughsecond lead 16 is connected to grounded parts.In following description to earthing method, the shell of communication terminal is used as grounded parts and independent grounded parts need not be provided in communication terminal.Yet, also can use independent grounded parts as required.

Fig. 5 is the diagrammatic sketch of an example of the inside of communication terminal according to an embodiment of the invention, wherein shows thesecond housing 100B of the communication terminal shown in Fig. 2 or Fig. 3.

In the following description, shell is indicated by " 100X " and is not divided into fore shell and back cover.This is the position of not limiting grounded parts.Therefore shell 100X can represent first and/or second shell.
