When BTB device does not fasten (or fastening not firm), mobile phone failure will lead to, such as: causing the display device of mobile phone that can not connect with handset single-plate, and then mobile phone screen can not be lighted.After mobile phone breaks down, it can not determine that failure whether since BTB device causes, influences the efficiency of fault location at present.
Summary of the invention
The embodiment of the present invention provides method, terminal and the detection device of a kind of detection BTB fastening reliability, it is capable of detecting when whether BTB device does not fasten (or fastening not firm), and then it is able to confirm that whether failure is to improve the efficiency of fault location as caused by the BTB device in device when device breaks down.
In order to achieve the above objectives, the embodiment of the present invention adopts the following technical scheme that
First, do the structure for the BTB that the technical program is related to illustrate: the BTB is for connecting the first device and the second device, and the BTB is made of the first connecting element of mutual snapping and the second connecting element, first connecting element is connect with the first device, and second connecting element is connect with the second device.By the way that the first connecting element and the second connecting element to be plugged in together, so that BTB be fastened, it is also achieved that the connection of the first device and the second device.
In a first aspect, disclosing a kind of method that detection board to board connector BTB fastens reliability: the described method includes:
Detection device obtains the output voltage of detection circuit first, and whether the input voltage of the output voltage and detection circuit that secondly judge the detection circuit is identical.
If the output voltage of the detection circuit is identical as the input voltage of the detection circuit, it is determined that the BTB fastens reliable；If the output voltage of the detection circuit is not identical as the input voltage of the detection circuit, it is determined that it is unreliable that the BTB is fastened.
What needs to be explained here is that, why the fastening reliability of the BTB can be judged by comparing the input voltage and output voltage of detection circuit, it is because the detection circuit is followed in series to form by the N group detection pin of the BTB, and each group of detection pin in the N group detection pin of the BTB is constituted by being set to the first detection pin of first connecting element and being set to the second detection pin of second connecting element respectively, when first connecting element and the second connecting element snapping, the first detection pin is connected with the second detection pin.In addition, N is positive integer.
The first connecting element of BTB is connect reliably with the second connecting element, which is equivalent to a conductor, and ideally, pressure drop would not be generated by being respectively arranged between one group of detection pin of the first connecting element, the second connecting element.If every group of detection pin of BTB is all connected with reliably, then will not all generate pressure drop between the concatenated detection pin of any two in detection circuit, the output voltage of detection circuit is identical as input voltage at this time.Counter push away can obtain, if the output voltage of detection circuit is identical as the input voltage of detection circuit, judge all not generate pressure drop between the concatenated detection pin of any two in the detection circuit, therefore can determine whether that BTB connection is reliable.
When the first connecting element and the second connecting element fasten loosely, the contact impedance between the first connecting element and the second connecting element is caused to change, the impedance between one group of detection pin on first connecting element, the second connecting element also just changes, it just will form pressure drop between the two detection pins, the output voltage of detection circuit caused to reduce compared to input voltage.When the first connecting element and the second connecting element do not fasten, cause not turning between the first connecting element, one group of detection pin on the second connecting element, will be breaking between two detection pins on first connecting element, the second connecting element, therefore detection circuit can not form access, lead
The output voltage for causing detection circuit is zero.Counter push away can obtain, if the output voltage of detection circuit and the input voltage of detection circuit be not identical (may be output voltage be less than input voltage or output voltage be zero), then judge there is open circuit or partial pressure between the concatenated detection pin in the detection circuit, therefore it is unreliable to can determine whether that BTB is fastened.
