Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] The components of the embodiments of this application described and illustrated in the accompanying drawings can typically be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0032] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in a generally used dictionary) shall be interpreted as having the same meaning as in the context of the relevant technical field and shall not be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Considering that existing technologies require manual soldering to adjust the resistance and capacitance values ​​in the peripheral circuitry of the load board, which is time-consuming and labor-intensive, greatly increasing the complexity and cost of testing, this application provides a debug board 10 and a load board. The debug board 10 provides two sets of component slots. When debugging the load board, the debug board 10 is connected to the load board. Operators can quickly replace resistors and / or capacitors by plugging and unplugging components in the slots, enabling flexible connection between components and the load board. Furthermore, the resistance and / or capacitance values ​​can be quickly switched via the movable connector 17, improving debugging flexibility and making testing more efficient and reliable.

[0035] The following describes the debugging board 10 with reference to some specific embodiments.

[0036] Figure 1 shows a schematic diagram of a debugging board 10 according to an embodiment of this application. Exemplarily, the debugging board 10 includes: a first set of component slots 11, a second set of component slots 12, a first connection terminal 13, a second connection terminal 14, a first line 15 electrically connected to the first connection terminal 13, a second line 16 electrically connected to the second connection terminal 14, and a connector 17. It is understood that the number of first and second slots can be set according to the actual application. The first set of component slots 11 can contain any number of first slots, for example, 2-10. The second set of component slots 12 can contain any number of second slots. Exemplarily, as shown in Figure 1, the first set of component slots contains five first slots, and the second set of component slots contains five second slots.

[0037] The positions of the first line 15 and the second line 16 can be set according to the actual application. The first line 15 and the second line 16 can be set at both ends of the debugging board 10, or they can be set at the same end of the debugging board 10. Taking the two ends of the debugging board 10 as an example, the first line 15 and the second line 16 can be set symmetrically at the top and bottom along the horizontal central axis of the debugging board 10, respectively. Alternatively, the first line 15 and the second line 16 can be symmetrically set on the left and right sides of the debugging board 10 along the vertical central axis of the debugging board 10, respectively. Setting the lines symmetrically along the central axis can reduce interference such as signal reflection and crosstalk, and ensure the integrity of the signal.

[0038] The slot in this application can have any structure, and can be configured according to the pins of the components in the actual application. The slot in this application can be a pin-type socket, a spring-type socket, a bayonet-type socket, a through hole, or a blind hole, etc. By setting the slot, components can be quickly replaced.

[0039] The first connection terminal 13 and the second connection terminal 14 are used for electrical connection with external circuits. The debugging board 10 can be connected in parallel with the external circuit or in series with the external circuit. It is understood that the debugging board 10 of this application is not limited to debugging the load board, but can also debug any kind of circuit that needs to be debugged. The external circuit connected to the debugging board 10 can be the circuit of the load board, or any kind of circuit such as a power supply circuit, digital circuit, communication circuit, or hybrid circuit.

[0040] Specifically, the first connecting terminal 13 and the second connecting terminal 14 can be connected to the circuit board carrying the external circuit by soldering. The first connecting terminal 13 and the second connecting terminal 14 can also be connected to the circuit board carrying the external circuit by pluggable connectors.

[0041] The first slots of the first group of component slots 11 are respectively positioned above the first line 15 along the thickness direction of the debugging board 10. The second slots of the second group of component slots 12 are respectively positioned above the second line 16 along the thickness direction of the debugging board 10. The slots are connected to the circuit via a movable connector 17. Exemplarily, along the thickness direction of the debugging board 10, the first line 15 and the second line 16 are positioned at the bottom layer of the debugging board 10, the connector 17 moves at the next bottom layer, the slots are positioned in the middle layer of the debugging board 10, and the top layer above the slots is used to place components. Specifically, each first slot is used to support one end of each component during debugging, and each second slot is used to support the other end of each component during debugging. It is understood that the components can be resistors, capacitors, or other two-pin devices, etc.

[0042] Connector 17 is movably mounted on the debugging board 10. When debugging with the current component, connector 17 is moved to the slot position that holds the current component, so that the current component is electrically connected to the external circuit through connector 17. Specifically, if debugging is performed using a resistor, resistors with different parameters are inserted into the slots of the debugging board 10. When debugging with a resistor of the current parameter is required, connector 17 is moved to the slot position where the resistor of the current parameter is inserted, so that the slot where the resistor of the current parameter is inserted is connected to the circuit below through connector 17, thereby connecting to the external circuit that needs to be debugged. For example, the two ends of a 10Ω resistor are inserted into the two slots in the first row, the two ends of a 100Ω resistor are inserted into the two slots in the second row, and the two ends of a 1KΩ resistor are inserted into the two slots in the third row. When debugging with a 100Ω resistor is required, connector 17 is moved to the second-bottom position corresponding to the two slots in the second row. Connector 17 connects the left slot in the second row to the first circuit and the right slot in the second row to the second circuit.

[0043] Understandably, the length of connector 17 can be adjusted according to the actual application. The length of connector 17 can be the same as the distance between the first set of component slots 11 and the second set of component slots 12; for example, both ends of connector 17 can be positioned below the slots. Alternatively, the length of connector 17 can be greater than the distance between the first set of component slots 11 and the second set of component slots 12. For example, one and both ends of connector 17 can extend from the slots to the outside of the test board 10, facilitating movement of connector 17. Exemplarily, the length of connector 17 can be the same as the distance between the first set of component slots 11 and the second set of component slots 12. Understandably, the parts of connector 17 that contact the slots and wiring should be conductors to allow communication between the slots and wiring, while the parts of connector 17 that do not contact the slots and wiring should be insulators to prevent short circuits in the components; for example, both ends of connector 17 can be conductors, and the middle part can be an insulator.

[0044] Furthermore, multiple connectors 17 can be set on the debugging board 10. By moving the multiple connectors 17, multiple components can be used to debug the external circuit, meeting different debugging needs and enhancing the flexibility and convenience of debugging.

[0045] The debugging board 10 of this application embodiment is equipped with multiple slots, which facilitates the installation of multiple components with different parameters. By setting a connector 17 between the slots and the circuit, when it is necessary to change the parameters of the components, the components can be flexibly connected to the external circuit by moving the connector 17, which greatly improves the debugging efficiency. In addition, this application is small and portable, and can be inserted into the circuit board at any time for use as an independent component, which greatly improves the debugging flexibility and makes the testing work more efficient and reliable.

[0046] In one embodiment, based on the above embodiments, Figure 2 shows another structural schematic diagram of the debugging board 10 according to an embodiment of this application. The debugging board 10 further includes a guide rail device 18, and a connector 17 is disposed on the guide rail device 18. The guide rail device 18 is used to slide the connector 17 to the slot position that carries the current component when debugging with the current component. Specifically, the guide rail device 18 is a slide rail, through which the connector 17 slides. The position of the guide rail device 18 can be set according to the actual application. The guide rail device 18 can be disposed between the first line 15 and the second line 16, or it can be disposed outside the first line 15 or outside the second line 16. Exemplarily, the guide rail device 18 is disposed between the first line 15 and the second line 16, located at the longitudinal central axis position of the debugging board 10.

[0047] The debugging board 10 of this application embodiment provides a fixed track for the connector 17 by setting a slide rail, which can reduce errors caused by human operation, improve the debugging accuracy, and fix the position of the connector 17 to prevent failures caused by the movement of the connector 17, thus ensuring the reliability of the debugging board 10.

[0048] In one embodiment, based on the above embodiment, the first connection terminal 13 includes a first series terminal 131, and the second connection terminal 14 includes a second series terminal 141. When at least two debugging boards 10 are connected in series for debugging, the first series terminal 131 of each debugging board 10 is connected to the second series terminal 141 of its adjacent debugging board 10. The position and connection method of the series terminals can be set according to the actual application. Exemplarily, as shown in FIG3, the first series terminal 131 and the second series terminal 141 of each debugging board 10 are symmetrically arranged along the central axis of the debugging board 10. The arrows in FIG3 indicate the direction of current when two debugging boards 10 are connected in series. It should be understood that the figure only shows a schematic diagram when debugging is performed using the uppermost component, and other components can be used for debugging according to the actual situation.

[0049] The first series terminal 131 of the preceding debug board 10 is pluggable to the second series terminal 141 of the following debug board. This pluggable connection allows for quick adjustment of the circuit structure, reducing the time and complexity of manual operation and lowering the risk of misoperation.

[0050] In one embodiment, based on the above embodiments, FIG4 shows a schematic diagram of a structure in which two debugging boards 10 are connected in parallel according to an embodiment of the present application. The first connection terminal 13 includes a first parallel terminal 132 and a third parallel terminal 133, and the second connection terminal 14 includes a second parallel terminal 142 and a fourth parallel terminal 143. When debugging is performed using at least two debugging boards 10 connected in parallel, the first parallel terminal 132 of each debugging board 10 is connected to the third parallel terminal 133 of the adjacent debugging board 10, and the second parallel terminal 142 of each debugging board 10 is connected to the fourth parallel terminal 143 of the adjacent debugging board 10. The first parallel terminal 132 and the second parallel terminal 142 of each debugging board 10 are symmetrically arranged along the central axis of the debugging board 10, and the third parallel terminal 133 and the fourth parallel terminal 143 of each debugging board 10 are symmetrically arranged along the central axis of the debugging board 10. It can be understood that the parallel terminals can be symmetrical along the longitudinal central axis or along the transverse central axis. As an example, as shown in Figure 4, the first parallel terminal 132 and the second parallel terminal 142 of each debugging board 10 are symmetrically arranged along the transverse central axis of the debugging board 10, and the third parallel terminal 133 and the fourth parallel terminal 143 of each debugging board 10 are symmetrically arranged along the transverse central axis of the debugging board 10. Through symmetrical arrangement, the balance of the debugging board 10 can be ensured, the overall stability can be enhanced, and wiring and connection can be facilitated, improving the appearance of the product.

[0051] Furthermore, Figure 5 shows another structural schematic diagram of the debugging board 10 according to an embodiment of this application. The first connection terminal 13 includes a first series terminal 131, a first parallel terminal 132, and a third parallel terminal 133. The second connection terminal 14 includes a second series terminal 141, a second parallel terminal 142, and a fourth parallel terminal 143. Depending on the actual application, the series and parallel terminals can be used to connect the debugging boards 10 in series and parallel. For example, as shown in Figure 6, the third parallel terminal 13 of the first debugging board 10 can be connected... 3. Connect the first parallel terminal 132 of the next debugging board, and connect the fourth parallel terminal 143 of the previous debugging board 10 to the second parallel terminal 142 of the next debugging board, so that the two debugging boards 10 are connected in parallel. Connect the parallel terminal of one of the debugging boards 10 to the external circuit, or connect the first series terminal 131 in the first connection terminal 13 and the second series terminal 141 in the second connection terminal 14 to the external circuit respectively. This way, the components on the debugging board 10 that are connected to the first line 15 and the second line 16 through the connector 17 can be connected in parallel to the external circuit.

[0052] The debugging board 10 in this embodiment of the application achieves series and parallel connections between debugging boards 10 through the splicing of connection terminals. It can be freely combined as needed to construct arbitrarily complex circuits. Debugging can be performed by adding debugging boards 10 as required, without the need to manufacture new circuit boards. Furthermore, this splicing connection allows users to quickly adjust the circuit structure, such as changing from series to parallel connections or adding more components. Compared to manual soldering or flying wire connections, this method greatly improves debugging efficiency and reduces the time and complexity of manual operations. In addition, if a module fails, the faulty part can be isolated by disconnecting the connection, and then a new module can be replaced. This modular maintenance method greatly simplifies the repair process and reduces maintenance costs.

[0053] This application also provides a load board, which, exemplary, includes a load board body and the aforementioned debugging board 10. The load board body and the debugging board 10 are electrically connected. Specifically, the load board may include a power module, a signal input / output module, a control module, and a protection module, etc. When the load board needs to be debugged, it is connected to the debugging board 10 by soldering, plugging and unplugging, or wire connection, and the load board is debugged using the components of the debugging board 10.
