The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Fig. 1 is a schematic diagram illustrating a structure of a detection circuit according to an exemplary embodiment. As shown in fig. 1, the detection circuit may include a first circuit board 1, a first connector 2, a second circuit board 3, a second connector 4, and a connection circuit board 5. The first circuit board 1 is connected with the first connector 2, the second circuit board 3 is connected with the second connector 4, and the connecting circuit board 5 can be connected with the first connector 2 and the second connector 4, so that signal transmission between the first circuit board 1 and the second circuit board 3 is realized. Specifically, the first connector 2 may include a plurality of first pins 21, the second connector 4 may include a plurality of second pins 41, and the connection circuit board 5 may implement signal transmission between the first circuit board 1 and the second circuit board 3 by connecting the first pins 21 and the second pins 41. The connection between the first connector 2 and the first circuit board 1, and the connection between the second connector 4 and the second circuit board 3 are usually implemented by fastening pins of the connectors to corresponding connection circuit boards, and if the connectors are tilted, deviated, deformed or dislocated in the fastening process, the impedance is abnormal, and then the related functions of the electronic device are easily affected, the first circuit board 1 may include a main board of the electronic device configured with the detection circuit, and the second circuit board 3 may include a secondary board, for example, a power connection circuit board related to a battery, or a connection circuit board related to a camera module, which is not limited by the present disclosure.
Therefore, based on the above situation, in order to detect whether the connection between the connector and the connection circuit board is normal, the detection circuit in the present disclosure may further include a power source 6, a preset resistor 7 and a voltage detection component 8, the connection circuit board 5 may include a detection trace 51, one end of the detection trace 51 is connected to the first pin 21, and the other end is connected to the second pin 41, the power source 6 is connected to the first connector 2, and an electrical signal output by the power source 6 is merged into a ground point after passing through the first pin 21, the detection trace 51, the second pin 41 and the preset resistor 7 which are connected in series, and the voltage detection component 8 is connected in parallel to the first pin 21, the second pin 41 and the preset resistor 7, so as to be able to detect voltages at two ends of the circuit including the first pin 21, the second pin 41 and the preset resistor 7 which are connected in series. Since the resistance values between the first pin 21 and the second pin 41 are different in both cases of normal connection and abnormal connection of the connector to the connection circuit board, the voltages detected by the voltage detection member 8 are different in both cases. Therefore, it is possible to determine whether or not the connections between the first connector 2 and the first circuit board 1, the second connector 4 and the second circuit board 3 are normal based on the voltage detected by the voltage detection member 8.
For example, still referring to fig. 1, assuming that the predetermined resistance includes a resistance R, further the equivalent between the first pin 21, the detection trace 51 and the second pin 41 on the first connector 2 is equivalent to the resistance R1, so that the equivalent circuit diagram shown in fig. 2 can be obtained. As shown in fig. 2, if the power supply 6 outputs a constant current I, if the first connector 2 is well fastened to the first circuit board 1 and the second connector 4 is well fastened to the second circuit board 2, the resistance of the resistor R1 is very small and can be substantially ignored, so that the voltage detected by the voltage detection component 8 is I × R, where R is the resistance of the preset resistor 7; if the first connector 2 is not well fastened to the first circuit board 1, or the second connector 4 is not well fastened to the second circuit board 3, or both of them are not well fastened, R1 has a certain resistance, the voltage detected by the voltage detection component 8 is I (R + R1), if the connector is connected to the reference ground in a staggered manner, the voltage detected by the voltage detection component 8 is 0, and if the connector is connected to other pin pins in a wrong manner, the voltage detected by the voltage detection component 8 is I Rother. Based on this, it is possible to determine whether or not the connection between the connector and the connection circuit board is normal by determining the comparison of the detected voltage value with a preset value threshold. The preset threshold may be a single value or a range of values, and may be obtained through multiple experiments.
By way of further example, the preset resistor may include a plurality of resistors, in which case the power supply 6 may be a constant current output or a constant voltage output, and the disclosure is not limited thereto. As shown in fig. 3, the preset resistance may include a first preset resistance 71 and a second preset resistance 72, and further assuming that the equivalent between the first pin 21, the detection trace 51 and the second pin 41 on the first connector 2 is a resistance R, an equivalent circuit diagram as shown in fig. 4 can be obtained. As shown in fig. 4, it is assumed that the power supply 6 outputs a constant voltage VCC, the first preset resistor 71 has a resistance value of R1, and the second preset resistor 72 has a resistance value of R2. Then, the voltage can be detected by using a voltage division principle, that is, as shown in fig. 3, the voltage detection component 8 is only connected in parallel with the first preset resistor 71, if the first connector 2 is well fastened with the first circuit board 1 and the second connector 4 is well fastened with the second circuit board 2, the resistance of the resistor R is very small and can be basically ignored, so that the voltage detected by the voltage detection component 8 is VCC R1/(R1+ R2); if the first connector 2 and the first circuit board 1 are not well fastened, or the second connector 4 and the second circuit board 3 are not well fastened, R is greater than zero and cannot be ignored, the voltage detected by the voltage detection component 8 is VCC (R + R1)/(R + R1+ R2), if the connector is connected to the reference ground in a staggered manner, the voltage detected by the voltage detection component 8 is 0, and if the connector is connected to other pin pins in an error manner, the resistance value of the resistor R is the resistance value corresponding to the other pin pins, and the voltage detected by the voltage detection component 8 is VCC (Rother + R1)/(Rother + R1+ R2).
Based on this, it is possible to determine whether or not the connection between the connector and the connection circuit board is normal by determining the comparison of the detected voltage value with a preset value threshold. The preset threshold may be a single value or a range of values, and may be obtained through multiple experiments. Of course, in the embodiment shown in fig. 3, when the power supply 6 outputs a constant current, it can also be determined whether the connector is normally connected to the corresponding connection circuit board by detecting the voltages at the two ends of the equivalent resistor R, the first preset resistor 71 and the second preset resistor 72.
According to the embodiment, whether the connection between the connection circuit board and the connection circuit board is abnormal or not can be judged through the voltage detected by the voltage detection component, so that most of the problems of poor connection can be eliminated before the electronic equipment provided with the detection circuit 100 leaves a factory, the subsequent after-sale problems are reduced, and the production cost is reduced.
It should be noted that: a first circuit board 1 is illustrated as a connection circuit board located at an upper side in fig. 1 of the present disclosure, and a power source 6 is connected to the first connector 2; it is to be understood that, when the connection circuit board located at the upper side in fig. 1 is the second circuit board 3, then the power source 6 may be connected to the second connector 4, and the disclosure is not limited thereto.
In this embodiment, the detection circuit may have various embodiments, which may include one circuit or may also include a plurality of branches, and the following description will be made in a centralized embodiment thereof:
in an embodiment, still referring to fig. 1, the connection circuit board 4 may include a plurality of detection traces connected in series, and an input end of the plurality of detection traces connected in series is connected to the power supply 6, and an output end thereof is connected to the ground point. For example, as shown in fig. 1 and 3, the connection circuit board 5 may include a first detection trace 511 and a second detection trace 512, the first detection trace 511 and the second detection trace 512 are connected in series, and the input end of the series connection is a first pin connected to the second detection trace 512, the first pin is connected to the power supply 6, and the output end of the series connection is a first pin connected to the detection trace 511, the first pin is connected to the ground point. For the convenience of circuit connection, the voltage detection component 8 may be connected in parallel with the first pin 21 and the second pin 41 corresponding to the first detection trace 511, and the first pin 21 and the second pin 41 corresponding to the second detection trace 512, and the preset resistor.
In this case, if the preset resistor 7 includes one resistor, the power supply 6 outputs a constant current at this time, as shown in fig. 1, the one resistor may connect the input end of the detection lines and the power supply 6 after being connected in series, or, as shown in fig. 5, the one resistor may also connect the output ends of the detection lines and the grounding point after being connected in series. The present disclosure is not limited.
In addition, if the predetermined resistor includes a plurality of resistors connected in series, the plurality of resistors may be located on the same connecting circuit board, and at least one of the plurality of resistors is located between the input terminal and the power supply, and the other resistors are located between the output terminal and the ground point. For example, as shown in fig. 3, the preset resistor 7 may include a first preset resistor 71 and a second preset resistor 72 connected in series, where the first preset resistor 71 is connected between the input terminal and the power source 6, and the second preset resistor 72 is connected between the output terminal and the ground point. Still alternatively, as shown in fig. 6, the first preset resistor 71 and the second preset resistor 72 are both connected between the output terminal and the ground point, but in other embodiments, the first preset resistor 71 and the second preset resistor 72 may be both connected between the input terminal and the power source 6, and the disclosure is not limited thereto.
In another embodiment, the detection circuit may include a plurality of branches, each branch including a detection trace, a first pin 21 and a second pin 41 corresponding to the detection trace, a predetermined resistor, and a ground point, which are connected in series. The detection circuit can also comprise a plurality of voltage detection components, and the voltage detection components 8 correspond to the branch circuits one by one, so that the pin connection failure corresponding to which detection wiring is particularly determined is facilitated.
In one case, as shown in fig. 7, each branch includes a predetermined resistor, each branch corresponds to a power supply, and the power supply is a constant current output. For example, as shown in fig. 7, the detection circuit includes a first branch located on the left side of fig. 7 and a second branch located on the right side of fig. 7, the power supply 6 may include a first power supply 61 and a second power supply 62, the preset resistor 7 may include a third preset resistor 73 and a fourth preset resistor 74, the voltage detection component 8 may include a first voltage detection component 81 and a second voltage component 82, the detection trace 51 may include a first detection component 511 and a second detection component 512, an electrical signal output by the first power supply 61 passes through the first detection trace 511 and the first preset resistor 71 and then enters a corresponding grounding point to form a first branch, and the first voltage detection component 81 is connected in parallel with at least the first pin 21 and the second pin 41 connected in series with the first detection component 511; the electrical signal output by the second power source 62 passes through the second detection trace 512 and the second preset resistor 72 and then enters the corresponding ground point to form a second branch, and the second voltage detection component 82 is at least connected in parallel with the first pin 21 and the second pin 41 connected in series with the first detection component 512.
In this embodiment, the predetermined resistor and the grounding point included in each branch are located on the same circuit board. As shown in fig. 8, there is another case that the predetermined resistor and the grounding point included in the branch may be located on different circuit boards. Of course, it is understood that when there are multiple branches, there may be one or multiple branches with their preset resistors and grounding points located on the same circuit board, and there may be one or multiple branches with their preset resistors and grounding points located on different circuit boards, and the disclosure is not limited thereto. When the preset resistor and the grounding point on the branch circuit are located on different circuit boards, the grounding point of the branch circuit should be a grounding point, and the grounding point is isolated from other grounding points on the connecting circuit board.
In another case, each branch may include a plurality of preset resistors, and at least two branches of the plurality of branches correspond to the same power supply or each branch may correspond to one power supply, and each branch may be provided with one voltage detection component 8 for performing voltage detection. For example, as shown in fig. 9, the detection circuit includes a first branch located on the left side in fig. 9 and a second branch located on the right side in fig. 9, the first branch may include a first preset resistor 71, a first voltage detection component 81, a detection trace 511, and a second preset resistor 72 connected in series, the second branch may include a fifth preset resistor 75, a second voltage detection component 82, a detection trace 512, and a sixth preset resistor 76 connected in series, and the first branch and the second branch may share the same power source 6, or as shown in fig. 10, the first branch may be disposed corresponding to the first power source 61 and the second branch may be disposed corresponding to the second power source 62. Wherein, the first branch or the second branch may also adopt the circuit structure shown in fig. 3, and the disclosure is not limited.
In this embodiment, as shown in fig. 9, the plurality of preset resistors corresponding to any branch circuit may be located on different circuit boards, that is, in fig. 9, the first preset resistor 71 corresponding to the first branch circuit is located on the first circuit board 1, the second preset resistor 72 is located on the second circuit board 3, the fifth preset resistor 75 corresponding to the second branch circuit is located on the first circuit board 1, and the sixth preset resistor 76 is located on the second circuit board 3. Alternatively, as shown in fig. 10, the multiple preset resistors corresponding to any branch may be located on the same circuit board, that is, in fig. 10, the first preset resistor 71 and the second preset resistor 72 corresponding to the first branch are both located on the first circuit board 1, and the fifth preset resistor 75 and the sixth preset resistor 76 corresponding to the second branch are both located on the first circuit board 1, and of course, may also be both located on the second circuit board 3, which is not described herein again. When the plurality of preset resistors 7 corresponding to any branch circuit are located on the same circuit board, the grounding point corresponding to any branch circuit should be a dedicated grounding point for the grounding point, so that signal confusion is avoided, and the detection result is not affected.
It should be noted that, in the case where there is a common power supply for a plurality of branches, the common power supply is a constant voltage output, and when there is a power supply for each branch, the power supply is a constant current output or a constant voltage output. For example, the power source 6 shown in fig. 9 is a constant voltage output, and the power source 61 and the power source 62 shown in fig. 10 may be either a constant current output or a constant voltage output.
In the above embodiments, when the connector is not properly engaged, the engagement between the pins at the two side edges of the connector and the circuit is usually abnormal. Therefore, the plurality of wires included in the connection circuit board 5 in the present disclosure may include two edge detection wires, and the edge detection wires are connected to the first pin 21 located at the edge of the first connector 2 and the second pin 41 located at the edge of the second connector 4, so that most of the bad connection conditions can be eliminated through the two detection wires located at the edges, which is beneficial to improving the detection efficiency.
In the technical scheme of the present disclosure, for example, the detection trace 51 is prevented from affecting other signal lines in the connection circuit board 5, and the detection trace 51 may be an isolation line between different signal lines in the connection circuit board 5, so as to avoid specially setting the detection trace for the detection circuit, thereby reducing the cost and not affecting signal transmission.
