Abstract
A kind of switching circuit board, comprise a circuit board body, it is characterized in that: described switching circuit board also comprises extricates from code switch, one first connector and one second connector more, described first connector comprises multiple first pin, described first connector comprises multiple second pin, each first pin connects all input pins that extricates from code switch, and described multiple second pin correspondence connects the output pin often extricating from code switch.Described switching circuit board can adjust the annexation of described multiple first pin and described multiple second pin.
Description
Technical field
The utility model is about a kind of circuit board, espespecially a kind of switching circuit board.
Background technology
The display screen of current mobile terminal, the display screen of such as mobile phone, need to test being assembled to before in mobile phone, existing a kind of testing circuit board and switching circuit board, testing circuit board stores the test program for testing display screen, switching circuit board connects described testing circuit board by a connecting line, and the circuit board be connected with display screen is connected described switching circuit board by another connecting line.But because the model of display screen is different, some is different for the output pin order of its correspondence, therefore, when testing, needing to change different switching circuit boards and connecting, very inconvenience.
Utility model content
In view of above content, be necessary the switching circuit board of the annexation that a kind of adjustable two connector corresponding pins are provided.
A kind of switching circuit board, comprise a circuit board body, it is characterized in that: described switching circuit board also comprises extricates from code switch, one first connector and one second connector more, described first connector comprises multiple first pin, described first connector comprises multiple second pin, each first pin connects all input pins that extricates from code switch, and described multiple second pin correspondence connects the output pin often extricating from code switch.
In one embodiment, often extricate from code switch and comprise four toggle switchs.
In one embodiment, each toggle switch comprises ten and dials key.
Compared to prior art, in the utility model, described switching circuit board comprises multiple toggle switch, stirs the annexation that described toggle switch can adjust the pin of two connectors.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a stereogram of the better embodiment of the utility model switching circuit board.
Fig. 2 is the enlarged drawing of II part in Fig. 1.
Fig. 3 is a front elevation of Fig. 1.
Embodiment
Refer to Fig. 1 and Fig. 2, the switching circuit board of better embodiment of the present utility model comprises a circuit board body 10, extricates from code switch 20,1 first connector 30 and one second connector 40 more.Described first connector 30 comprises multiple first pin, and described second connector 40 comprises multiple second pin.Described first connector 30 is for connecting a testing circuit board, and described second connector 40 is for connecting a circuit board be connected with display screen to be measured.
Each toggle switch 20 comprises multiple groups of keys 21, and in the present embodiment, described toggle switch 20 has 10 to dial key 21, and often extricating from code switch 20 has 4.Often extricate from the quantity of code switch 20 according to the number of the second pin of the second connector 40, such as, the second pin number of the second connector 40 is 36, and the quantity often extricating from code switch 20 is 4, guarantees there is corresponding second pin of abundant group key.
Each first pin connects all input pins that extricates from code switch 20, and the different output pins of described toggle switch 20 connect the second corresponding pin.Like this for different display panel type, by stirring the annexation dialling multiple first pin and described multiple second pin described in key and adjustable of described toggle switch 20, thus testing circuit board is mated with described display screen; Such as, the power pins in all first pins is in the 3rd position, and the position of power pins in all second pins is in the second place, second of the toggle switch 20 of the power pins in connection first pin is dialled key and stirs and be communicated with.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection range, as long as realize the purpose of this utility model with substantially identical means all should belong to protection range of the present utility model.
