Description

Communication terminal

[technical field]

The utility model relates to communication technical field, particularly relates to a kind of communication terminal.

[background technology]

Along with the development of the mobile communication terminal device such as mobile phone, panel computer, the appearance requirement of people to mobile communication terminal device is also more and more higher.And there is the communication terminal of metal shell, the texture had due to it and anti-wear performance receive liking of consumers in general.

But metal shell can form the effect of signal shielding to the Anneta module in mobile communication terminal device.In order to avoid metal shell potato masher antenna signal, the mobile communication terminal device of correlation technique can do nonmetal design usually to part relative with Anneta module on metal shell, remainder does metal designs.But there is boundary due to metallic member and non-metallic part in this design, can not ensure that the outward appearance of housing has higher consistency, have impact on the overall appearance of mobile communication terminal device.The another kind of mobile communication terminal device improved is by Anneta module bulk migration on metal shell, and using metal shell as antenna radiator, but this structure exists the defect that antenna resonant frequency and bandwidth are difficult to adjust.

Secondly, quite large on the impact of Anneta module with or without headroom.With regard to traditional Anneta module, the bandwidth sum efficiency of size to antenna of headroom has and important effect.Because have some devices and interlock circuit (as modules such as loud speaker, microphone, USB) under metal shell, make as the headroom under the metal shell of antenna radiator quite little, so just greatly increase the debugging difficulty of antenna.

Therefore, be necessary to provide a kind of novel communication terminal.

[utility model content]

The purpose of this utility model is to provide a kind of antenna resonant frequency and bandwidth to be easy to the communication terminal regulated.

The technical solution of the utility model is as follows: a kind of communication terminal, it comprises housing, the Anneta module be located at the mainboard in described housing and be located on mainboard, described housing comprises metal shell on the back, described metal shell on the back has casting coping and to insulate the metal middle cover be connected with described casting coping, described Anneta module comprises the data processing module be located on described mainboard, the point of excitation be electrically connected with described data processing module, at least one grounding leg, the first conductor be electrically connected with described point of excitation and the second conductor be electrically connected with described grounding leg, described point of excitation is electrically connected with described casting coping by the first conductor, described grounding leg is electrically connected with described casting coping by the second conductor.

Preferably, described mainboard is positioned at directly over described casting coping, and described first conductor and the second conductor are and are arranged on described mainboard and are the metal clips that is electrically connected with point of excitation and grounding leg respectively, and described metal clips abuts with described casting coping.

Preferably, described Anneta module is LTE antenna module, and the bandwidth of described LTE antenna module is 824MHz-960MHz or 1710MHz-2690MHz.

The beneficial effects of the utility model are: the point of excitation of Anneta module passes through the first conductor direct feed to casting coping, using casting coping as antenna radiator, and the earth point of Anneta module is electrically connected with casting coping by the second conductor, by the position of regulated ground point, the object of low-and high-frequency resonance frequency regulating Anneta module can be reached, have the advantages that the resonance frequency of Anneta module and bandwidth are easy to regulate.

[accompanying drawing explanation]

Fig. 1 is the structure broken away view of a kind of communication terminal of the utility model.

[embodiment]

Below in conjunction with drawings and embodiments, the utility model is described in further detail.

As shown in Figure 1, a kind of communication terminal 100 Anneta module of comprising housing, being located at the mainboard 103 in housing and being located on mainboard 103.In the preferred embodiment, Anneta module is LTE antenna module, and the bandwidth of this LTE antenna module is 824MHz-960MHz or 1710MHz-2690MHz.Anneta module also can be the Anneta module of other types or frequency range, such as diversity antenna module, WIFI Anneta module etc.The metal shell on the back 102 that housing comprises display screen 101 and is connected with display screen 101, display screen 101 and metal shell on the back 102 together form the receiving space of collecting mainboard 103.Metal shell on the back 102 has casting coping 102A and to insulate the metal middle cover 102B be connected with casting coping 102A.

Anneta module comprises the data processing module be located on mainboard 103, the point of excitation be electrically connected with data processing module, two grounding legs, the first conductor 104 be electrically connected with point of excitation and the second conductors 105 be electrically connected with grounding leg.Wherein, point of excitation is electrically connected with casting coping 102A by the first conductor 104, and two grounding legs are electrically connected with casting coping 102A respectively by two the second conductors 105.

In the preferred embodiment, mainboard 103 is positioned at directly over casting coping 102A, first conductor 104 is for being arranged on the metal clips be electrically connected on mainboard 103 and with point of excitation, and the second conductor 105 is for being arranged on the metal clips be electrically connected on mainboard 103 and with grounding leg.These metal clipss all abut with casting coping 102A.First conductor 104 and the second conductor 105 also can be play pin, and the point of excitation of Anneta module and earth point are mainly electrically connected with casting coping 102A by its effect.

The point of excitation of Anneta module is electrically connected with casting coping 102A by the first conductor 104, and namely Anneta module direct feed is to casting coping 102A, using casting coping 102A as antenna radiator, realizes the corresponding function of Anneta module.And the earth point of Anneta module is electrically connected with casting coping 102A by the second conductor 105, by regulating the position of each earth point, the low-and high-frequency resonance frequency of Anneta module can be regulated.In addition, different earth point ground connection can also be selected by switch, thus meet the wider requirement of low frequency.Therefore, even if the headroom of casting coping correspondence position is very little, resonance frequency and the bandwidth of Anneta module still can be regulated easily.

Above-described is only execution mode of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
