[0005] To achieve the above objectives, according to one aspect of the present invention, a PCB assembly is provided, comprising: a first PCB having a first through hole; a female connector including a first body and a first conductive element disposed on the first body, the first body having a second through hole communicating with the first through hole, a first end of the first conductive element being connected to the first PCB, a second end of the first conductive element extending into the second through hole, and the second end of the first conductive element being tilted upwards toward the axis of the second through hole; a second PCB; and a male connector capable of being plugged into and plugged into the female connector, the male connector including a second body and a second conductive element disposed on the second body, the first end of the second conductive element being connected to the second PCB; when the male connector is plugged into the female connector, the second end of the second conductive element extends into the second through hole and abuts against the second end of the first conductive element, and the second PCB is fitted to the first PCB.

[0006] Furthermore, on the axis of the second through hole, the length of the portion of the second conductive element located inside the second through hole is greater than the length of the portion of the first conductive element located inside the second through hole.

[0007] Furthermore, on the axis of the second through hole, the first PCB and the second PCB are located between the first end of the first conductive element and the first end of the second conductive element, and the distance between the first PCB and the second PCB is 0.

[0008] Furthermore, the second PCB is provided with a third through hole that communicates with the first through hole. The second seat includes a seat block and a first shoulder provided on the side wall of the seat block. When the male seat is inserted into the female seat, the seat block passes through the third through hole, the first through hole and the second through hole. The first shoulder is in the third through hole and cooperates with the first PCB stop. The second conductive element is provided on the seat block.

[0009] Furthermore, the base protrudes from the second through hole along the axis of the second through hole in a direction away from the second PCB.

[0010] Furthermore, a first mounting groove is provided on the side wall of the seat block, and the first end of the first mounting groove passes through the two surfaces opposite to the first shoulder along the axial direction of the second through hole. The second conductive element is provided on the first mounting groove.

[0011] Furthermore, the second end of the first mounting groove extends through the surface of the base block away from the second PCB along the axial direction of the second through hole, and the second end of the second conductive element extends along the axial direction of the second through hole toward the surface of the base block away from the second PCB.

[0012] Furthermore, the first seat body includes a seat sleeve and a second shoulder disposed on the outer side wall of the seat sleeve. The inner hole of the seat sleeve forms a second through hole. A second mounting groove is disposed on the inner side wall of the seat sleeve. A clearance groove communicating with the second mounting groove is disposed on the second shoulder. A first conductive element is disposed on the second mounting groove. The clearance groove avoids the first end of the first conductive element.

[0013] Furthermore, the first conductive component includes a connecting section, a fixing section, a raised section, and an abutting section connected in sequence. The connecting section is connected to the first PCB, the fixing section is fixed to the first base, the raised section is raised in the axial direction of the second through hole, and the abutting section is protruded in the axial direction of the second through hole. The raised section forms the second end of the first conductive component.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] According to one aspect of this application, a PCB assembly is provided, such as Figures 1 to 6As shown, the PCB assembly is elongated and includes: a first PCB 10, which has a first through hole 11; a female connector 20, which includes a first base 21 and a first conductive element 22 disposed on the first base 21, the first base 21 having a second through hole 23 communicating with the first through hole 11, the first end of the first conductive element 22 being connected to the first PCB 10, the second end of the first conductive element 22 extending into the second through hole 23, and the second end of the first conductive element 22 being tilted towards the axis L of the second through hole; a second PCB 30; and a male connector 40, which can be plugged into and plugged into the female connector 20, the male connector 40 including a second base 41 and a second conductive element 42 disposed on the second base 41, the first end of the second conductive element 42 being connected to the second PCB 30; when the male connector 40 is plugged into the female connector 20, the second end of the second conductive element 42 extends into the second through hole 23 and abuts against the second end of the first conductive element 22, and the second PCB 30 is fitted to the first PCB 10.

[0031] In the technical solution of the embodiment of the PCB assembly, when the male connector 40 is inserted into the female connector 20, the second end of the second conductive member 42 extends into the second through hole 23 and abuts against the second end of the first conductive member 22, and the second PCB 30 is fitted to the first PCB 10. Due to the second through hole 23, a sufficiently long second conductive member 42 can be placed, facilitating the abutment between the second end of the second conductive member 42 and the second end of the first conductive member 22. Furthermore, because the second PCB 30 is fitted to the first PCB 10, the distance between the second PCB and the first PCB can be reduced, allowing the PCB assembly to be arranged in a smaller space without considering the problem of component interference, and reducing the space occupied. Therefore, the technical solution of the PCB assembly embodiment effectively solves the problem in related technologies where arranging two PCBs in a smaller space while maintaining distance to avoid component interference results in a large space occupation. When the male connector 40 is inserted into the female connector 20, the second PCB 30 is fitted to the first PCB 10, and the second PCB 30 and the first PCB 10 are fixedly connected.

[0032] It should be noted that the above-mentioned elongated shape refers to a PCB assembly having length, width, and height, with its length being the largest dimension, and its length being at least twice its width or twice its height.

[0033] In order for the first conductive element 22 to be reliably fixed on the first PCB10, the first end of the first conductive element 22 is soldered on the first PCB10. In order for the second conductive element 42 to be reliably fixed on the second PCB30, the first end of the second conductive element 42 is soldered on the second PCB30.

[0034] The first conductive element 22 is preferably a pin, and the second conductive element 42 is preferably a plug.

[0035] like Figures 1 to 4 As shown, on the axis L of the second through hole, the length of the portion of the second conductive element 42 located within the second through hole 23 is greater than the length of the portion of the first conductive element 22 located within the second through hole 23. This design, by increasing the length of the second conductive element 42, ensures that even when the second PCB 30 and the first PCB 10 are fully bonded, the second conductive element 42 can still make full contact with the second end of the first conductive element 22, achieving a stable electrical connection.

[0036] like Figures 1 to 4 As shown, on the axis L of the second through hole, the first PCB 10 and the second PCB 30 are located between the first end of the first conductive element 22 and the first end of the second conductive element 42, and the distance between the first PCB 10 and the second PCB 30 is 0. This design achieves zero-pitch bonding between the second PCB 30 and the first PCB 10, eliminating the distance that must be maintained between the second PCB 30 and the first PCB 10 to avoid component interference, greatly reducing the overall thickness of the PCB assembly, thereby enabling the effective arrangement of the PCB assembly in a confined space.

[0037] like Figures 1 to 4 As shown, the second PCB 30 is provided with a third through hole 31 communicating with the first through hole 11. The second seat 41 includes a seat block 411 and a first shoulder 412 provided on the side wall of the seat block 411. When the male connector 40 is inserted into the female connector 20, the seat block 411 passes through the third through hole 31, the first through hole 11, and the second through hole 23. The first shoulder 412 is inside the third through hole 31 and cooperates with the stop of the first PCB 10. The second conductive element 42 is provided on the seat block 411. The design of the first shoulder 412 limits the insertion depth of the male connector 40, ensuring that the second conductive element 42 and the second end of the first conductive element 22 are in the correct position for contact. At the same time, the stop function ensures the firmness of the connection and prevents over-insertion or loosening during insertion and removal.

[0038] Specifically, there are two first shoulders 412, and the two first shoulders 412 are symmetrically arranged with respect to the axis L of the second through hole.

[0039] like Figures 1 to 4 As shown, the seat block 411 protrudes from the second through hole 23 along the axis L of the second through hole in a direction away from the second PCB 30. The protruding design of the seat block 411 increases the insertion and extraction force between the male connector 40 and the female connector 20, ensuring the reliability of the connection, and also facilitates the setting of a longer second conductive element 42.

[0040] like Figures 3 to 6As shown, a first mounting groove 413 is provided on the side wall of the seat block 411. The first end of the first mounting groove 413 extends through the two opposing surfaces of the first shoulder 412 along the axis L of the second through hole. The second conductive element 42 is disposed on the first mounting groove 413. The design of the first mounting groove 413 ensures that the second conductive element 42 is firmly fixed on the seat block 411, while ensuring the axial positioning of the second conductive element 42 and ensuring the stability of the electrical connection. At the same time, the axial through-hole design of the first mounting groove 413 guides the second conductive element 42 to be precisely aligned with the first through hole 11, facilitating installation.

[0041] Specifically, the sidewalls of the seat block 411 are two sidewalls arranged opposite to each other, that is, the first mounting groove 413 is provided on both sidewalls.

[0042] like Figures 3 to 6 As shown, the second end of the first mounting groove 413 extends along the axis L of the second through hole into the surface of the base block 411 facing away from the second PCB 30. The second end of the second conductive element 42 extends along the axis L of the second through hole toward the surface of the base block 411 facing away from the second PCB 30. The extended design of the second conductive element 42 ensures that its second end can penetrate deeply into the second through hole 23, avoiding a reduction in the insertion depth of the second conductive element 42 due to space constraints. The second end of the second conductive element 42 achieves effective electrical contact with the second end of the first conductive element 22, thereby ensuring the reliability of the contact for conduction.

[0043] like Figures 3 to 6 As shown, the first base 21 includes a base sleeve 211 and a second shoulder 212 disposed on the outer side wall of the base sleeve 211. The inner hole of the base sleeve 211 forms a second through hole 23. A second mounting groove 213 is disposed on the inner side wall of the base sleeve 211. A clearance groove 214 communicating with the second mounting groove 213 is disposed on the second shoulder 212. A first conductive component 22 is disposed on the second mounting groove 213. The clearance groove 214 avoids the first end of the first conductive component 22. The second mounting groove 213 enables the first conductive component 22 to be firmly fixed. At the same time, the existence of the clearance groove 214 avoids interference between the first conductive component 22 and the first PCB 10, so that the first end of the first conductive component 22 can be reliably connected to the first PCB 10. It also avoids interference with the components on the first PCB 10, which facilitates the assembly of the male connector 40 and the female connector 20 on the first PCB 10 and the second PCB 30.

[0044] Specifically, the inner wall of the seat cover 211 includes two inner walls that are arranged opposite to each other, that is, a second mounting groove 213 is provided on each of the two inner walls.

[0045] Specifically, there are two second shoulders 212, and the two second shoulders 212 are symmetrically arranged with respect to the axis L of the second through hole.

[0046] like Figures 3 to 6 As shown, the first conductive element 22 includes a connecting section 221, a fixing section 222, a raised section 223, and an abutting section 224 connected in sequence. The connecting section 221 is connected to the first PCB 10, the fixing section 222 is fixed to the first base 21, the raised section 223 is raised towards the axis L of the second through hole, and the abutting section 224 is protruded towards the axis L of the second through hole. The raised section 223 forms the second end of the first conductive element 22. When the male connector 40 is inserted into the female connector 20, the abutting section 224 abuts against the second end of the first conductive element 22. The fixing section 222 facilitates the fixing of the first conductive element 22 to the first base 21, the raised section 223 allows the first conductive element 22 to still contact the second conductive element 42 even in space-constrained conditions, and the protruding abutting section 224 ensures contact area and contact pressure, optimizing the quality of electrical connection and enabling electrical connection even in a very small space.

[0047] According to another aspect of this application, an LED display device is provided. An embodiment of the LED display device includes an LED display screen and a PCB assembly that cooperates with the LED display screen. The PCB assembly is the aforementioned PCB assembly. Since the aforementioned PCB assembly can solve the problem in related technologies where two PCBs arranged in a small space occupy a large amount of space to maintain distance to avoid interference between components, the LED display device including this PCB assembly can also solve the same technical problem. Furthermore, applying the aforementioned optimized PCB assembly to the LED display device can not only significantly reduce the wiring space requirements inside the display device, but also improve the stability and electrical connection performance of the male connector 40 and female connector 20 through zero-pitch connection, thereby enhancing the applicability of the LED display device in confined spaces or high-density wiring environments.
