Description
[technical field]
The utility model relates to a kind of proving installation of function button plate.
[background technology]
At present, along with intelligent television is more and more universal, every platform intelligent electric machine all can wear a function button plate, and such function button plate generally has several button, is used for operating some major functions of TV.But these function button plates existing, when dispatching from the factory, all do not have special equipment to test the performance of these function button plates, the qualification rate that these function button plates are produced like this can not control, and can cause bad impact to market.
Therefore, be necessary to solve as above problem.
[utility model content]
The utility model overcomes the deficiency of above-mentioned technology, and provide a kind of proving installation of function button plate, it is easy to use, and practicality is good, and testing efficiency is high.
For achieving the above object, the utility model have employed following technical proposal:
A kind of proving installation of function button plate, it is characterized in that the row wire terminal 10 including linkage function keypad each key testing interface and the power connection 20 be connected with extraneous power supply, also include the LED group 30 be arranged in order, the negative line of described power connection 20 is all connected with the negative electricity of each LED of LED group 30, be electrically connected with the positive pole of each LED respectively again after the equal resistance in series R of extension line of described row wire terminal 10, the electrode line of described power connection 20 is electrically connected on the extension line of a wherein row wire terminal, and the LED be electrically connected with this extension line is power light 31.
The proving installation of a kind of function button plate as above, it is characterized in that the extension line of described row wire terminal 10 has 8, described resistance R has 8, and each bar extension line is corresponding with each resistance R connects one by one.
The proving installation of a kind of function button plate as above, is characterized in that the resistance of described each resistance R is all identical.
The proving installation of described a kind of function button plate, is characterized in that the resistance of described resistance R is 100 ohm.
The beneficial effects of the utility model are:
Row wire terminal only need be received on the test interface of function button plate by the utility model, and power connection is electrically connected to extraneous power supply, and at this moment, power light is just energized bright light, provides power supply normal to indicate.Press the button on function button plate with hand afterwards, when the button on a function button plate is wherein pressed, corresponding LED in LED group, if lighted, then shows that this keypress function is normal, so corresponding to other function button.If press a certain button, corresponding LED does not light, then show this function button existing defects, this product exists quality problems.This proving installation is easy to use, and practicality is good, and testing efficiency is high, and circuit structure is simple.
[accompanying drawing explanation]
Fig. 1 is test circuit figure of the present utility model.
Fig. 2 is circuit configuration figure of the present utility model.
[embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
As shown in Figure 1, a kind of proving installation of function button plate, the row wire terminal 10 including linkage function keypad each key testing interface and the power connection 20 be connected with extraneous power supply, include the LED group 30 be arranged in order in addition.The negative line of described power connection 20 is all connected with the negative electricity of each LED of LED group 30.Be electrically connected with the positive pole of each LED respectively again after the equal resistance in series R of extension line of described row wire terminal 10.The electrode line of described power connection 20 is electrically connected on the extension line of a wherein row wire terminal, and the LED be electrically connected with this extension line is power light 31.
Like this, only row wire terminal need be received on the test interface of function button plate, power connection is electrically connected to extraneous power supply, and at this moment, power light 31 just forms loop with power supply, and be just energized bright light, provides power supply normal to indicate.The button on function button plate is pressed afterwards with hand, when the button on a function button plate is wherein pressed, this button will with the extension line electric connection of corresponding row wire terminal, one of them LED in LED group is made to form loop, then in LED group, corresponding LED will light, then show that this keypress function is normal.So corresponding to other function button, if press a certain button, corresponding LED does not light, then show this function button existing defects, this product exists quality problems.
As the optimal way of the present embodiment, the extension line of described row wire terminal 10 has 8, and described resistance R has 8, and each bar extension line is corresponding with each resistance R connects one by one.And needing the function button plate of test to have 7 function buttons, another one extension line then takies to power light.The resistance of described each resistance R is all identical.The resistance of described resistance R is 100 ohm, adopts the resistance of much resistance R, can select according to actual needs.
