The utility model also discloses a mobile phone which comprises the LCD screen and the PCB board that are fixedly connected, and the electric connection structure is arranged between the LCD screen and the PCB board. In the utility model, the LCD screen and the PCB board are fixedly connected, and the electric connection between the LCD screen and the PCB board is conducted through contacting between the conducting contact pieces on the LCD screen and the pad on the PCB board, thus realizing the connection of signals; the electric connection structure is simple, and compared with the electric connection manners adopting welding or a connector in the prior art, the electric connection structure has lower cost and occupies less internal space.
Description
Technical field
The utility model relates to the communication apparatus technical field, more particularly, relates to the electric connection structure of a kind of LCD screen and pcb board and adopts the mobile phone of this structure.
Background technology
At present, the LCD of mobile phone screen mainly contains three kinds with the electric connection mode of pcb board.First kind is that welded type connects, and establishes a FPC (Flexible Printed Circuit, Flexible Printed Circuit) pad on the LCD screen, stays another pad with described FPC pad welding on pcb board, by the welding of two pads being realized being electrically connected of LCD screen and pcb board.This connected mode need take a long time when actual welding, and whether also need detect welding after the welding qualified, and also very inconvenient to the LCD maintenance under this mode; Second kind is Bto B connector to be set connect, and at the plug that a B to B is drawn on the mainboard next door of LCD screen, correspondingly reserves the socket of a B to B on pcb board, realizes being electrically connected of LCD screen and pcb board by plug with plugging together of socket.Though this connected mode is convenient, the cost height, and B to B connector can take more inner space; The third is to connect by FPC connector, on the LCD screen, draw one section FPC, on pcb board, leave corresponding another section FPC, by the connection realization LCD screen of two sections FPC and the signal conduction between the pcb board, this mode is the same with the second way, the cost height, FPC connector can take more inner space.
The utility model content
It is a kind of simple in structure and be easy to the electric connection structure of the LCD screen that assembles and keep in repair and pcb board and adopt the mobile phone of this structure that technical problem to be solved in the utility model is to provide.
For solving the problems of the technologies described above, the technical solution of the utility model is: the electric connection structure of a kind of LCD screen and pcb board, be located between fixedly connected the LCD screen and pcb board, comprise and be located at the some conductive contact blades on the described LCD screen and be located on the described pcb board and the pad that contacts with described conductive contact blade.
Further, described pad sets in a row, and described conductive contact blade is corresponding with pad locations.
Further, described LCD screen is provided with a support backlight, and described conductive contact blade is the sheet metal that is convexly set in described support backlight back.
Further, described sheet metal and described support backlight are one-body molded.
Another technical scheme of the present utility model is: a kind of mobile phone is provided, comprises fixedly connected LCD screen and pcb board, be provided with above-mentioned electric connection structure between described LCD screen and the pcb board.
LCD in technical solutions of the utility model screen is with after pcb board is fixedlyed connected, electrical connection between the two is to contact with the pad of pcb board by the conductive contact blade on the LCD screen, thereby realize the conducting of signal, the support backlight of this conductive contact blade and LCD screen is one-body molded, simple in structure and need not increase assembly process, than the available technology adopting welding manner, the utility model assembling easily, and is easy to maintenance; By B to B connector ways of connecting, the utility model has been saved B to B connector, and cost is lower, and B to B connector occupation space has also been saved in inside; By the FPC connector ways of connecting, the utility model has been saved FPC connector, and cost is lower, and the FPC connector occupation space has also been saved in inside.

Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1, Fig. 2, be a preferred embodiment of the present utility model, the electric connection structure 1 of a kind of LCD screen and pcb board, be located between fixedly connected the LCD screen 2 and pcb board 3, comprise and be located at the some conductive contact blades 11 on the described LCD screen 2 and be located on the described pcb board 3 and the pad 12 that contacts with described conductive contact blade 11.
With reference to Fig. 3, Fig. 4, described pad 12 sets in a row, and described conductive contact blade 11 is corresponding with pad 12 positions, and the two could guarantee effectively conducting between the contact point when contact like this.Certainly, described conductive contact blade 11 and pad 12 also can adopt other arrangement architecture.
Further, described LCD screen 2 is provided with a support 21 backlight, and described conductive contact blade 11 is for being convexly set in the sheet metal at described support backlight 21 backs.Described sheet metal and described support backlight 21 are one-body molded, saved the operation that sheet metal is installed like this, and integrated infrastructure cost are lower, and the inner space that takies still less is easier to maintenance and replacing.
The conductive contact blade 11 that shields on 2 by LCD between LCD in technical solutions of the utility model screen 2 and the pcb board 3 contacts with the pad 12 of pcb board 3, thereby realize the conducting of signal, this electric connection structure is than the available technology adopting welding manner, it is easier to assemble, and keeps in repair more convenient; By B to B connector ways of connecting, the utility model has been saved B to B connector, and cost is lower, and B to B connector occupation space has also been saved in inside; By the FPC connector ways of connecting, the utility model has been saved FPC connector, and cost is lower, and the FPC connector occupation space has also been saved in inside.
The utility model also provides a kind of mobile phone, comprises fixedly connected LCD screen 2 and pcb board 3, is provided with above-mentioned electric connection structure 1 between described LCD screen 2 and the pcb board 3.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
