[0003] Current automotive power distribution boxes are typically circuit board type, integrating relays and fuses onto a circuit board to supply power to various electrical components. However, this type of distribution box requires redesigning the circuit board when changing the wiring, and the assembly and soldering of components are all done manually, resulting in a long processing time. Summary of the Invention
[0004] The main objective of this invention is to provide a power supply circuit board for an automotive power distribution box, aiming to solve the technical problem that it takes a long time to modify the wiring of an automotive power distribution box.

The power supply circuit board includes a connecting strip and a plurality of first conductive strips and second conductive strips arranged in a crisscross pattern. The connecting strip is provided with an input terminal. The same end of the plurality of first conductive strips is connected to the connecting strip. The other end of the first conductive strip is provided with a first output terminal, and at least one end of the second conductive strip is provided with a second output terminal. The intersection point of the first conductive strip and the second conductive strip is provided with a mounting hole.
[0006] Preferably, the power supply circuit board of the vehicle power distribution box further includes a conductive ring arranged around the intersection point, and the conductive ring is connected to the first conductive strip and the second conductive strip constituting the intersection point respectively.

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] This invention proposes a power supply circuit board for an automotive power distribution box, such as... Figure 1 As shown, the power supply circuit board includes a connecting strip 10 and a plurality of first conductive strips 20 and second conductive strips 30 arranged in a crisscross pattern. The connecting strip 10 is provided with an input terminal 11. The same end of the plurality of first conductive strips 20 is connected to the connecting strip 10. The other end of the first conductive strip 20 is provided with a first output terminal 21, and at least one end of the second conductive strip 30 is provided with a second output terminal 31. The intersection point of the first conductive strip 20 and the second conductive strip 30 is provided with a mounting hole 40.
[0022] In this embodiment, the connecting strip 10, the first conductive strip 20, and the second conductive strip 30 are all made of conductive metal material. The length of the connecting strip 10 can be arranged according to actual needs, allowing it to connect to multiple first conductive strips 20 simultaneously. The first conductive strips 20 and second conductive strips 30 are preferably arranged in a crisscross pattern within a single plane, i.e., by stamping a metal plate with a punch press to obtain the crisscrossing arrangement of the first and second conductive strips 20 and 30. Alternatively, the connecting strip 10 can be formed by direct stamping. In this case, the first conductive strips 20 and second conductive strips 30 are preferably arranged perpendicularly. The number of first and second conductive strips 20 and 30 can be arranged according to actual needs. The connecting strip 10 has an input terminal 11 for convenient electrical connection to an external power source (i.e., a car battery). The first conductive strip 20 has a first output terminal 21 at its end away from the connecting strip 10, and at least one end of the second conductive strip 30 has a second output terminal 31, facilitating the output of electrical energy to different electrical appliances. At this point, to facilitate the installation of relays and fuses, mounting holes 40 are provided at the intersection points of the first conductive strip 20 and the second conductive strip 30, allowing the pins of the relays and fuses to be directly fixed in the mounting holes 40 or fixed in the mounting holes 40 via riveting terminals 3. In this embodiment, by crisscrossing the first conductive strips 20 and the second conductive strips 30, and connecting the same end of multiple first conductive strips 20 to the connecting strip 10, the first conductive strips 20 and the second conductive strips 30 can be cut according to the actual output terminal position to form different output circuits. Thus, when the power supply line needs to be changed, only the new power supply circuit board needs to be re-cut, which helps to reduce the time required to change the internal wiring of the distribution box. Specifically, the method of forming the actual power supply circuit using the power supply circuit board can be that the output points and the areas to be avoided are input in the design software, and the corresponding areas can be cut and designed using the software. Then, the areas to be cut can be punched using a stamping device to obtain the required power supply circuit.
[0023] In a preferred embodiment, such as Figures 1 to 3As shown, conductive rings 50 are arranged around the intersection points of the first conductive strip 20 and the second conductive strip 30, and the conductive rings 50 are connected to the first conductive strip 20 and the second conductive strip 30 forming the intersection points. Preferably, the conductive rings 50 and the first conductive strip 20 and the second conductive strip 30 are located in the same horizontal plane, that is, the conductive rings 50 are also stamped synchronously with the first conductive strip 20 and the second conductive strip 30. In this case, as... Figure 2 As shown, the points that can be cut at each intersection include a first cutting portion 24 on the first conductive strip 20, which is located in the area outside the conductive ring 50 and between the conductive ring 50 and the mounting hole 40; a second cutting portion 34 on the second conductive strip 30, which is located in the area outside the conductive ring 50 and between the conductive ring 50 and the mounting hole 40; and a third cutting portion 51 on the conductive ring 50, which is located in the area at the angle between the first conductive strip 20 and the second conductive strip 30. By appropriately cutting the first cutting portion 24, the second cutting portion 34 and the third cutting portion 51 at each intersection, multiple power supply circuits from the input terminal 11 to the first output terminal 21 or the second output terminal 31 are sequentially formed.
[0024] Furthermore, such as Figure 4 As shown, to increase the diversity of power supply circuits within the distribution box, it is preferable to combine multiple cut power supply circuit boards. This is achieved by sequentially inserting rivet pins into the mounting holes 40 on the stacked power supply circuit boards. A partition 4 is preferably provided between adjacent power supply circuit boards to prevent short circuits caused by contact between their power supply circuits. The rivet pins can be configured to be partially or fully conductive, depending on the actual situation. The rivet terminal 3 is simply connected to one end of the rivet pin, and this end of the rivet pin is conductive. Furthermore, the power supply circuit boards can be cut in such a way that power is supplied from the input terminal 11 of one power supply circuit board to the output terminal of another or more power supply circuit boards: input terminal 11 → intersection point (one power supply circuit board) → rivet pin → intersection point (another power supply circuit board) → output terminal.
[0025] In a preferred embodiment, to accommodate the distribution box, the outer diameter of the conductive ring 50 is 7mm and the inner diameter is 5mm. In this case, it is preferable that the center distance between two adjacent horizontal mounting holes 40 is 7.8mm, and the center distance between two adjacent vertical mounting holes 40 is 8.1mm. This facilitates the connection of the riveting terminal 3 to the fuse or relay after setting it on the mounting hole 40, thus adapting to fuses and relays of general specifications and allowing for arbitrary arrangement of the number of relays and fuses.
[0026] In a preferred embodiment, such as Figure 1 As shown, preferably, both ends of the second conductive strip 30 are provided with a second output terminal 31, which makes it easier to increase the number of output terminals and thus facilitate the supply of power to more electrical appliances.
[0027] In a preferred embodiment, such as Figure 1 As shown, in actual use of the distribution box, it is preferable to have twenty first conductive strips 20 and twelve second conductive strips 30, so as to accommodate the installation of two-pin fuses and four-pin or six-pin relays.
[0028] In a preferred embodiment, such as Figure 2 and Figure 4 As shown, to facilitate the output of electrical energy to the appliance through the first output terminal 21, the first output terminal 21 preferably includes a first transition strip 22 and a first guide pin 23. One end of the first transition strip 22 is connected to a corresponding first conductive strip 20, and the other end is connected to the first guide pin 23. Simultaneously, several first conductive strips 20 constitute a first conductive group 1, and the first guide pins 23 in each first conductive group 1 are arranged in parallel, thereby facilitating the integration of the first guide pins 23 in each first conductive group 1 into a single plug-in terminal 5 for convenient circuit connection of the appliance. Specifically, when there are twenty first conductive strips 20, it is preferable that five first conductive strips 20 constitute one first conductive group 1.
[0029] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, to facilitate the output of electrical energy to the appliance through the second output terminal 31, the second output terminal 31 preferably includes a second transition strip 32 and a second guide pin 33. One end of the second transition strip 32 is connected to a corresponding second conductive strip 30, and the other end is connected to the second guide pin 33. Simultaneously, several second conductive strips 30 constitute a second conductive group 2, and the second guide pins 33 in each second conductive group 2 are arranged in parallel, thereby facilitating the integration of the second guide pins 33 in each second conductive group 2 into a single plug-in terminal 5 for convenient circuit connection of the appliance. Specifically, when there are twelve second conductive strips 30, it is preferable that six second conductive strips 30 constitute one second conductive group 2.
[0030] In a preferred embodiment, such as Figure 1 As shown, the input terminal 11 is a conductive plate connected to the connecting strip 10, and the conductive plate is provided with a fixing hole 12. One end of the wire is fixed to the conductive plate by a screw passing through the fixing hole 12. At this time, the inner wall of the fixing hole 12 can be provided with a thread to cooperate with the screw, so that one end of the wire can be fixed to the conductive plate without contacting the external object. When multiple power supply circuit boards are combined, it is preferable that the conductive plates on each power supply circuit board are located in the same horizontal plane.
[0031] In a preferred embodiment, to facilitate the setting of a mounting hole 40 at the intersection of the first conductive strip 20 and the second conductive strip 30, the intersection is preferably a dot with a diameter of 3 mm, and the mounting hole 40 is a through hole set at the center of the dot. Preferably, the diameter of the mounting hole 40 is 1.6 mm. Simultaneously, the width of both the first conductive strip 20 and the second conductive strip 30 is 1.6 mm.
