Description
Technical field
The utility model relates to picture pick-up device, specifically, relates to a kind of pair of camera head module.
Background technology
Existing mobile phone only has a camera head mostly.Along with the third generation (3rdGeneration, 3G) the development of mobile communications network, mobile phone (being mobile phone) is also along with carrying out the 3Gization update, multimedia functions such as mobile phone can also be supported to take pictures when supporting visual telephone in order to make, video recording require 3G mobile to be equipped with two camera heads usually.The common mobile phone with two camera heads all has two separate camera head modules at present, two camera head modules have a cover camera head separately, connecting interface, and the printed circuit board (PCB) that connects camera head and connecting interface, printed circuit board (PCB) is provided with corresponding connecting line, therefore two interfaces that are connected correspondingly with two camera head modules must correspondingly be set on cell phone mainboard, must increase the space of cell phone mainboard and the difficulty of wiring like this, so that the mobile phone volume correspondingly increases, and manufacturing cost correspondingly improves, both do not meet the microminiaturized requirement of mobile phone, and brought great cost pressure for again mobile phone producer and upstream supplier thereof; In addition, at present vast cellphone subscriber thirsts for the mobile phone that only has a camera head originally upgraded quickly and easily becomes the mobile phone with two camera heads, to save the transition cost of mobile phone upgrading, but owing to have only an interface that is connected with the camera head module on its mainboard, and existing pair of camera head mobile phone technique requires must possess two corresponding interface on the mainboard, and therefore this quick upgrading can't realize.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pair of camera head module, this pair of camera head module cost is low, compact conformation, can be applicable to the two camera head mobile phones of 3G, and can will only have the mobile phone of mobile phone upgrading becoming with two camera heads of a camera head quickly and easily.The technical scheme that adopts is as follows:
A kind of pair of camera head module is characterized in that comprising first camera head, second camera head, a printed circuit board (PCB) and a connecting interface; First camera head is connected with connecting interface by same group of data signal line with second camera head, first camera head is connected with connecting interface by same group of control signal wire with second camera head, first camera head is connected with connecting interface by the first power switch signal line, and second camera head is connected with connecting interface by the second source switch signal line; Described data signal line, control signal wire, the first power switch signal line and second source switch signal line all are located on the described printed circuit board (PCB).
That is to say that an end of above-mentioned data signal line is connected with second camera head with first camera head simultaneously, the other end is connected with connecting interface; One end of control signal wire is connected with second camera head with first camera head simultaneously, and the other end is connected with connecting interface; One end of the first power switch signal line is connected with first camera head, and the other end is connected with connecting interface; One end of second source switch signal line is connected with second camera head, and the other end is connected with connecting interface.
In preferred version, above-mentioned printed circuit board (PCB) is flexible printed circuit board (FLEXIBLEPRINTED CIRCUITS BOARD is called for short FPC).
The particular location of first camera head, second camera head, overall dimension and display performance all can be according to the concrete application demand customizations of client.
In the utility model, two camera heads combine by same group of data signal line on the same printed circuit board (PCB) and same group of control signal wire and same connecting interface, replace two common independent camera head modules at present; Independently control the on/off of two camera heads by first separate power switch signal line and second source switch signal line, realize the selection and the switching of electrical functionality, make synchronization only allow one of them camera head in running order, and another camera head is in closed condition, avoids two camera heads signal each other to disturb.When the utility model is applied on the mobile phone, compare with existing two separate camera head modules that are used for mobile phone, have following advantage: saved a printed circuit board (PCB), one group of data signal line, one group of control signal wire and a connecting interface, the manufacturing cost aspect can be saved about 15%; Owing to externally only need a connecting interface, therefore can save the transition cost of upgrading quickly and easily with originally only having the mobile phone of mobile phone upgrading becoming with two camera heads of a camera head; Because externally only need a connecting interface, so structure is compact more, can reduce the space of corresponding 3G mobile mainboard and the difficulty of wiring, it is microminiaturized more to help mobile phone, and can effectively utilize space in the casing, makes handset structure compact more.
Description of drawings
Accompanying drawing is the structural representation of the utility model preferred embodiment.
Embodiment
As shown in drawings, this pair of camera head module comprises that first camera head 1, second camera head 2, flexible printed circuit board 3 and connecting interface 4, the first camera head 1 and second camera head 2 respectively are provided with a power-off function pin; First camera head 1 is connected with connecting interface 4 by same group of data signal line 5 with second camera head 2, first camera head 1 is connected with connecting interface 4 by same group of control signal wire 6 with second camera head 2, the power-off function pin of first camera head 1 is connected with connecting interface 4 by the first power switch signal line 7, and the power-off function pin of second camera head 2 is connected with connecting interface 4 by second source switch signal line 8; Data signal line 5, control signal wire 6, the first power switch signal line 7 and second source switch signal line 8 all are located on the flexible printed circuit board 3.
That is to say that an end of data signal line 5 is connected with second camera head 2 with first camera head 1 simultaneously, the other end is connected with connecting interface 4; One end of control signal wire 6 is connected with second camera head 2 with first camera head 1 simultaneously, and the other end is connected with connecting interface 4; One end of the first power switch signal line 7 is connected with the power-off function pin of first camera head 1, and the other end is connected with connecting interface 4; One end of second source switch signal line 8 is connected with the power-off function pin of second camera head 2, and the other end is connected with connecting interface 4.The technology general knowledge of the two ends of connecting lines such as data signal line 5, control signal wire 6, the first power switch signal line 7 and second source switch signal line 8 and concrete connection side this area owned by France of first camera head 1, second camera head 2 and connecting interface 4 is not described in detail at this.
Brief description is the operation principle of this pair camera head module once:
To be applied to mobile phone is example, and connecting interface 4 is connected with corresponding interface on the cell phone mainboard, and above-mentioned pair of camera head module is connected with hand-set host.Hand-set host is by the on/off of the first power switch signal line, 7 controls, first camera head 1, on/off by second source switch signal line 8 controls second camera head 2, that is to say, the power-off function pin of first camera head 1 and second camera head 2 is controlled separately by hand-set host, to realize the selection and the switching of first camera head 1 and second camera head, 2 electrical functionality; 6 of data signal line 5 and control signal wires are shared by first camera head 1 and second camera head 2.
