[0002] Printed circuit boards (PCB boards) are one of the important components of electronic products. They have the advantages of high reliability, good consistency, high mechanical strength, light weight, small size, and easy standardization. They have been widely used in electronic products such as electronic watches, calculators, computers, communication equipment, and electronic radar systems.

[0003] At present, every product with a printed circuit board needs to be programmed on the printed circuit board. In traditional technology, due to the limited height and space when making the PCB jig, it is difficult to design the pin header / connector at the communication port, and considering the cost effect, the original method of using the connector interface for programming has been gradually cancelled in the existing technology, and it is replaced by designing probe points on the PCB and using the probe of the programming equipment for programming. However, the existing manual programming method using the probe point probe is often accompanied by the phenomenon of incomplete programming due to poor contact between the probe and the probe point or too small contact area, and its defective rate is relatively high. Utility Model Content

[0004] In order to solve the above technical problems, the utility model aims to provide a circuit board probe point structure which can first determine whether the probe and the probe point are in good contact before programming.

[0038] like Figure 1 , Figure 2 and Figure 3As shown, the utility model provides a circuit board probe point structure, which is arranged on a circuit board 100. The circuit board 100 can be programmed with information of the circuit board 100 by means of the circuit board probe point structure and a programming device 200 arranged thereon; the circuit board probe point structure includes a first probe point group 10, a second probe point group 20 and a light emitting element 30 (in one embodiment, the light emitting element 30 is, for example, a light emitting diode); the first probe point group 10 includes a first probe point 101 and a second probe point 102, the first probe point 101 is connected to a first end 301 of the light emitting element 30 (in one embodiment, the first probe point 102 is connected to a first end 302 of the light emitting element 30). One end 301 is, for example, the cathode of a light-emitting diode), the second probe point 102 is electrically connected to a line terminal of the circuit board 100 (not shown, the line terminal serves as a signal input port for subsequent information burning); the second probe point group 20 includes a third probe point 201 and a fourth probe point 202, the third probe point 201 is connected to the second end 302 of the light-emitting element 30 (in one embodiment, the second end 302 is, for example, the anode of a light-emitting diode), and the fourth probe point 202 is electrically connected to another line terminal of the circuit board (not shown, the other line terminal serves as another signal input port for subsequent information burning).

[0039] In one embodiment, the burning device 200 includes a first probe group 40 and a second probe group 50, and the first probe group 40 and the second probe group 50 are combined on a mounting plate 60 of the burning device 200, wherein the first probe group 40 corresponds to the first probe point group 10 of the circuit board probe point structure in the utility model, and the second probe group 50 corresponds to the second probe point group 20 of the circuit board probe point structure in the utility model. Specifically, the first probe group 40 has a first probe 401 corresponding to the first probe point 101 and a second probe 402 corresponding to the second probe point 102; the second probe group 50 has a third probe 501 corresponding to the third probe point 201 and a fourth probe 502 corresponding to the fourth probe point 202.

[0040] When information needs to be burned on the circuit board 100, the first probe 401 and the second probe 402 are located on the same probe pen as the first probe group 40. When the first probe group 40 is pressed down, the first probe 401 and the second probe 402 are synchronously contacted with the first probe point 101 and the second probe point 102 respectively (or, the first probe 401 contacts the first probe point 101, and at the same time, the second probe 402 is synchronously contacted with the second probe point 102); and the third probe 501 and the fourth probe 502 are the second probe group 50 are located on the same probe pen, when the second probe group 50 is pressed down, the third probe 501 and the fourth probe 502 are synchronously in contact with the third probe point 201 and the fourth probe point 202 respectively (or, the third probe 501 is in contact with the third probe point 201, and at the same time, the fourth probe 502 is synchronously in contact with the fourth probe point 202); if the light-emitting element 30 is lit, it means that the first probe 401 is in good contact with the first probe point 101 and the third probe 501 is in good contact with the third probe point 201 (because the light-emitting element 30 is lit, it means that the light-emitting element 30. The first probe point 101 and the third probe point 201 form a closed loop through the first probe 401 and the third probe 501), which also indicates that the second probe 402 is in good contact with the second probe point 102 and the fourth probe 502 is in good contact with the fourth probe point 202 (because the second probe 402 and the first probe 401 are located on the same probe pen, the first probe 401 is in good contact with the first probe point 101, which indirectly indicates that the second probe 402 is in good contact with the second probe point 102; and the fourth probe 502 is in good contact with the third probe 501 are located on the same probe pen, so the third probe 501 is in good contact with the third probe point 201, which indirectly indicates that the fourth probe 502 is in good contact with the fourth probe point 202); then, when it has been determined that the second probe 402 is in good contact with the second probe point 102 and the fourth probe 502 is in good contact with the fourth probe point 202, the burning device 200 can burn information on the circuit board 100 by means of the second probe 402 and the second probe point 102 and the fourth probe 502 and the fourth probe point 202.

[0041] In one embodiment, when information needs to be burned into the circuit board 100, the host (not shown) of the burning device 200 first inputs a first potential (the first potential is, for example, a ground potential) to the first probe point 101 through the first probe 401, and inputs a second potential (the second potential is, for example, a power supply voltage VCC) different from the first potential to the third probe point 201 through the third probe 501; if the light-emitting element 30 emits light, it indicates that the first probe 401 and the first probe point 101 and the third probe 501 and the third probe point 201 are in good contact, and it also indicates that the second probe 402 and the second probe point 102 and the fourth probe 502 and the fourth probe point 202 are in good contact; then, the host (not shown) of the burning device 200 inputs a first burning signal to the second probe point 102 through the second probe 402, and inputs a second burning signal to the fourth probe point 202 through the fourth probe 502 to realize information burning of the circuit board 100.

[0042] The circuit board probe point structure of the utility model has a first probe point group and a second probe point group. Compared with the prior art, the probe point structure only has the second probe point and the fourth probe point as the burning process. The utility model further provides a first probe point, a third probe point and a light emitting element. The first probe point of the first probe point group, the third probe point of the second probe point group and the light emitting element are electrically connected to each other to serve as a basis for judging whether the contact between the probe (the second probe point, the fourth probe point) and the probe point (the second probe point, the fourth probe point) to be subjected to the burning process is good (if the first probe contacts the first probe point and the third probe contacts the third probe point, the light emitting element emits a light). If light is emitted, it indicates that the first probe and the first probe point are in good contact and the third probe and the third probe point are in good contact. If the first probe and the first probe point are in good contact, it indirectly indicates that the second probe and the second probe point are in good contact. If the third probe and the third probe point are in good contact, it indirectly indicates that the fourth probe and the second probe point are in good contact). The burning process is performed only after the first probe point of the first probe point group, the third probe point of the second probe point group and the light-emitting element determine that the probes (the second probe, the fourth probe) and the probe points (the second probe point, the fourth probe point) are in good contact. In this way, incomplete burning will not occur, and the yield rate of the information burning process can be greatly improved.

[0043] Figure 4 for Figure 2 For a schematic diagram of the first probe group and the second probe group in another embodiment, please refer to Figure 4In this embodiment, in order to further ensure stable electrical contact between the second probe 402 and the second probe point 102 and to further ensure stable electrical contact between the fourth probe 502 and the fourth probe point 202, the second probe 402 has a first spring element 4021, and the fourth probe 502 has a second spring element 5021. When it is necessary to burn information on the circuit board 100, after the light-emitting element 30 emits light, the first spring element 4021 in the second probe 402 can be used to further press the second probe 402 to further ensure that a stable electrical connection is formed between the second probe 402 and the second probe point 102 (the light-emitting element 30 emits light, which means that an effective electrical contact is formed between the first probe 401 and the first probe point 101, which indirectly means that an effective electrical contact is formed between the second probe 402 and the second probe point 102, then the first spring element 4021 in the second probe 402 is used to further press the second probe 402 to increase the contact area between the second probe 402 and the second probe point 102 to further ensure that the second probe 402 and the second probe point 102 are in a stable electrical connection. 102), and the second spring element 5021 in the fourth probe 502 is used to further press the fourth probe 502 downward to further ensure that a stable electrical connection is formed between the fourth probe 502 and the fourth probe point 202 (the light-emitting element 30 emits light, which means that an effective electrical contact is formed between the third probe 501 and the third probe point 201, which indirectly indicates that an effective electrical contact is formed between the fourth probe 502 and the fourth probe point 202. Then, the second spring element 5021 in the fourth probe 502 is used to further press the fourth probe 502 downward, so that the contact area between the fourth probe 502 and the fourth probe point 202 can be increased to further ensure that a stable electrical connection is formed between the fourth probe 502 and the fourth probe point 202).

[0044] Figure 5 This is an enlarged schematic diagram of the first exploration point. Figure 6 For the enlarged schematic diagram of the third exploration point, please refer to Figure 5 and Figure 6In one embodiment, the first probe point 101 has a first contact 1011 and a first virtual contact 1012. When the first probe 401 is not pressed down to contact the first probe point 101, the first contact 1011 and the first virtual contact 1012 are in a disconnected state (i.e., the first contact 1011 and the first virtual contact 1012 are not in direct contact with each other, and the two are set at a certain distance), and the first end 301 of the light emitting element 30 is connected to the first virtual contact 1012; when the first probe 401 is pressed down to contact the first probe point 101, the first contact 1011 and the first virtual contact 1012 are in a short-circuited state (i.e., the first contact 1011 and the first virtual contact 1012, which were originally set at a certain distance, are electrically connected to each other by the first probe 401). Similarly, the third probe point 201 has a second contact 2011 and a second virtual contact 2012. When the third probe 501 is not pressed down to contact the third probe point 201, the second contact 2011 and the second virtual contact 2012 are in a disconnected state (that is, the second contact 2011 and the second virtual contact 2012 are not in direct contact with each other, and the two are set at a certain distance), and the second end 302 of the light-emitting element 30 is connected to the second virtual contact 2012; when the third probe 501 is pressed down to contact the third probe point 201, the second contact 2011 and the second virtual contact 2012 are in a short-circuited state (that is, the second contact 2011 and the second virtual contact 2012, which were originally set at a certain distance, are electrically connected with each other through the third probe 501).

[0045] In the above embodiment, whether an effective electrical connection is formed between each probe and its corresponding probe point is confirmed by whether the light emitting element 30 emits light or not. However, it is not limited thereto. In other embodiments, whether an effective electrical connection is formed between each probe and its corresponding probe point can also be confirmed by other electronic elements. For example, the light emitting element 30 in the above embodiment is replaced by a resistor element 70. At the same time, the burning device 200 is provided with a prompt element 80 (such as a buzzer or a current display screen) corresponding to the action of the resistor element 70. In this way, it is also possible to confirm whether an effective electrical connection is formed between each probe and its corresponding probe point before the burning process.

[0046] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 , Figure 7 This is a schematic diagram of a circuit board probe point structure of another embodiment of the utility model. The main difference between this embodiment and the above embodiment is that in this embodiment, a resistor element replaces the light-emitting element in the above embodiment, and a prompt element is added to the burning device at the same time, while the arrangement, function and structure of other elements are similar to those in the above embodiment.

[0047] Specifically, in this embodiment, the circuit board probe point structure of the utility model includes a first probe point group 10, a second probe point group 20 and a resistor element 70; the first probe point group 10 includes a first probe point 101 and a second probe point 102, the first probe point 101 is connected to the first end 701 of the resistor element 70, and the second probe point 102 is electrically connected to a line terminal of the circuit board 100 (not shown, the line terminal serves as a signal input port for subsequent information burning); the second probe point group 20 includes a third probe point 201 and a fourth probe point 202, the third probe point 201 is connected to the second end 702 of the resistor element 70, and the fourth probe point 202 is electrically connected to another line terminal of the circuit board (not shown, the other line terminal serves as another signal input port for subsequent information burning).

[0048] In one embodiment, the programming device 200 includes a first probe group 40, a second probe group 50 and a prompt element 80 (such as a current display screen or a buzzer). The first probe group 40 and the second probe group 50 are combined on a mounting plate 60 of the programming device 200. The first probe group 40 corresponds to the first probe point group 10 of the circuit board probe point structure of the utility model, and the second probe group 50 corresponds to the second probe point group 20 of the circuit board probe point structure of the utility model. Specifically, the first probe group 40 has a first probe 401 corresponding to the first probe point 101 and a second probe 402 corresponding to the second probe point 102; the second probe group 50 has a third probe 501 corresponding to the third probe point 201 and a fourth probe 502 corresponding to the fourth probe point 202;

[0049] When information needs to be burned on the circuit board 100, the first probe 401 and the second probe 402 are located on the same probe pen as the first probe group 40. When the first probe group 40 is pressed down, the first probe 401 and the second probe 402 respectively and synchronously contact the first probe point 101 and the second probe point 102 (or, the first probe 401 contacts the first probe point 101, and at the same time, the second probe 402 synchronously contacts the second probe point 102); and the third probe 501 and the fourth probe 502 are located on the same probe pen as the second probe group 50. When the second probe group 50 is pressed down, the third probe 501 and the fourth probe 502 respectively and synchronously contact the third probe point 201 and the fourth probe point 202 (or, the third probe 501 contacts the third probe point 201, and at the same time, the fourth probe 502 synchronously contacts the fourth probe point 202). If the prompt element 80 sends a prompt signal, it means that the first probe 401 is in good contact with the first probe point 101 and the third probe 501 is in good contact with the third probe point 201 (because the prompt element 80 sends a prompt signal, it means that the resistor 70, the first probe point 101 and the third probe point 201 form a closed loop through the first probe 401 and the third probe 501), and it also means that the second probe 402 is in good contact with the second probe point 102 and the fourth probe 502 is in good contact with the fourth probe point 202 (because the second probe 402 and the first probe 401 are located on the same probe pen, so the first probe 401 is in good contact with the first probe point 101, that is, the indirect Grounding indicates that the second probe 402 is in good contact with the second probe point 102; and the fourth probe 502 and the third probe 501 are located on the same probe pen, so the third probe 501 is in good contact with the third probe point 201, which indirectly indicates that the fourth probe 502 is in good contact with the fourth probe point 202); then, when it has been determined that the second probe 402 is in good contact with the second probe point 102 and the fourth probe 502 is in good contact with the fourth probe point 202, the burning device 200 can burn information on the circuit board 100 through the second probe 402 and the second probe point 102 and the fourth probe 502 and the fourth probe point 202.

[0050] It should be noted that, in one embodiment, the prompt element 80 is a current display screen, and a prompt current displayed on the current display screen is the prompt signal, which indicates that the first probe 401 is in good contact with the first probe point 101 (indirectly indicating that the second probe 402 is in good contact with the second probe point 102) and the third probe 501 is in good contact with the third probe point 201 (indirectly indicating that the fourth probe 502 is in good contact with the fourth probe point 202). However, it is not limited to this. In another embodiment, the prompt element 80 is a buzzer, and a prompt sound emitted by the buzzer is the prompt signal, which indicates that the first probe 401 is in good contact with the first probe point 101 (indirectly indicating that the second probe 402 is in good contact with the second probe point 102) and the third probe 501 is in good contact with the third probe point 201 (indirectly indicating that the fourth probe 502 is in good contact with the fourth probe point 202).

[0051] In one embodiment, when information needs to be burned into the circuit board 100, the host (not shown) of the burning device 200 first inputs a first potential to the first probe point 101 through the first probe 401, and inputs a second potential different from the first potential (for example, the second potential is higher than the first potential) to the third probe point 201 through the third probe 501; if the prompt element 80 (for example, a current display screen or a buzzer) sends a prompt signal (the current display screen displays a prompt current or the buzzer sends a prompt sound), it means that the first probe 401 and the first probe point 101 and the third probe 501 and the third probe point 201 are in good contact, and it also means that the second probe 402 and the second probe point 102 and the fourth probe 502 and the fourth probe point 202 are in good contact; then, the host (not shown) of the burning device 200 inputs a first burning signal to the second probe point 102 through the second probe 402, and inputs a second burning signal to the fourth probe point 202 through the fourth probe 502 to realize information burning of the circuit board 100.

[0052] To sum up, compared with the circuit board probe point structure in the prior art, the circuit board probe point structure of the utility model additionally adds two probe points and a connectivity detection element (such as a light emitting diode or a resistor element. If it is a resistor element, the burning equipment needs to be equipped with a corresponding buzzer / current display screen) to confirm whether an effective electrical connection is formed between each probe and each probe point. After determining that an effective electrical connection has been formed between each probe and each probe point, the information burning process of the circuit board is performed through the corresponding probes and probe points. In this way, incomplete burning will not occur, and the yield rate of the information burning process can be greatly improved.
