Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more specifically, to a stackable integrated circuit board. Background Technology

[0002] An integrated circuit board (PCB) is a miniature electronic device or component. Sometimes, to reduce installation space, multiple PCBs are stacked in multiple layers. While stacking reduces space, replacing or repairing the PCBs or individual components requires disassembling all layers, making the process cumbersome and inconvenient. Therefore, we propose a stackable integrated circuit board. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a stackable integrated circuit board to solve the technical problem of troublesome maintenance of current stacked circuit boards.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stackable integrated circuit board, comprising multiple fixed layers, wherein the top center of each fixed layer is recessed, a holding plate is provided in the recessed portion, a PCB board is placed on top of the PCB board, a limiting plate is installed on the side of each fixed layer, the bottom of the limiting plate contacts and limits the movement of the PCB board, a cavity is formed inside one side of each fixed layer, a drive control structure is provided inside the cavity, and a telescopic rod and a connecting rod are provided between the limiting plate and the upper fixed layer.

[0005] Preferably, the drive control structure includes two arc plates, and a guide post is provided between the two arc plates. The arc plates are arc-shaped, and the top and bottom of the arc plates are fitted with the inner wall of the cavity to form a limit.

[0006] Preferably, one of the arc plates is connected to a connecting column on one side, the connecting column passes through the fixed layer plate and is fixed to the side of the holding plate, and the fixed layer plate is provided with a long groove for the connecting column to slide.

[0007] Preferably, a plurality of pins are installed on one side of the other arc plate, and a plurality of sockets are provided on the inner wall of the cavity. The plurality of pins and sockets are arranged in an array at the same distance, and a spring is provided between the two arc plates.

[0008] Preferably, the telescopic rod is composed of multiple telescopic sleeves that are interlocked, with the top and bottom ends of the telescopic sleeves being fixed to the fixed layer plate and the limiting plate, respectively.

[0009] Preferably, the limiting plate has an elongated groove, one end of the connecting rod is located inside the elongated groove, and both ends of the connecting rod are hinged to the holding plate and the fixing plate, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the cooperation of the fixing plate and the holding plate and the constraint of the limiting plate on the PCB board, makes the PCB board more stable when placed. The connection between the two arc plates and the holding plate, as well as the constraint of the pins, combined with the cooperation of the springs, allows the holding plate to be pulled out as a whole or partially pulled out during maintenance, depending on the number of layers to be maintained. The constraint of the pins can further constrain the pulled-out part to prevent displacement, eliminating the need for complete disassembly during maintenance, improving the convenience of maintenance, and solving the problem of troublesome maintenance of stacked circuit boards.

[0012] 2. This utility model also utilizes the interlocking tenon joints of multiple sections of the telescopic rod and the constraint of the connecting rod, as well as the connection between the connecting rod, the holding plate, and the connecting column, to enable the corresponding number of layers to be opened when the holding plate is pulled out, thereby increasing the space for the maintenance of the layers that need to be maintained. This, combined with the maintenance state of the pulled-out part, further solves the problem of troublesome maintenance of stacked circuit boards. Attached Figure Description

[0019] like Figures 1 to 4As shown, this utility model relates to a stackable integrated circuit board, including multiple fixed layer plates 1, which are placed layer by layer. The top center of each fixed layer plate 1 is recessed, and a holding plate 2 is provided in the recessed part. An opening is provided on one side of each fixed layer plate 1, allowing the holding plate 2 to slide in and out through the opening along the recessed part. A PCB board 3 is placed on top of the fixed layer plate 3. A limiting plate 4 is installed on the side of each fixed layer plate 1, with its bottom contacting and limiting the PCB board 3. A telescopic rod 6 is fixed between the limiting plate 4 and the upper fixed layer plate 1, thereby achieving overall stacking. To provide limiting and easy extraction, a cavity is provided inside one side of each fixed layer plate 1, and a drive control structure 5 is provided inside the cavity. The drive control structure 5 includes two arc plates 501, which are arc-shaped. The top and bottom of the arc plates 501 are in contact with the inner wall of the cavity to form a limiting effect. A connecting post 502 is connected to one side of one of the arc plates 501. The connecting post 502 passes through the fixed shelf 1 and is fixed to the side of the holding plate 2. The fixed shelf 1 has a long groove for the connecting post 502 to slide. The long groove cooperates with the connecting post 502. When the arc plate 501 is pulled, it can drive the holding plate 2 to move. Several pins 503 are installed on one side of the other arc plate 501. Multiple insertion holes are opened in the inner wall of the cavity. The multiple pins 503 and insertion holes are distributed in an array at the same distance. A spring 504 is set between the two arc plates 501. The spring 504 has the force to push the two arc plates 501 apart. Since one of them is fixed to the holding plate 2, that is, the position is fixed, the other arc plate 501 will drive the pins 503 to insert into the insertion hole. Thus, when there is no force, it can achieve the effect of fixing the holding plate 2. In order to improve the stability of the fixation, a guide post 8 is inserted vertically between the two arc plates 501. One end of the guide post 8 is fixed to the arc plate 501 near the holding plate 2, and the other end is inserted through the other arc plate 501.

[0020] Working principle: When maintenance is required, pressing the two arc plates 501 will compress the spring 504, causing the pin 503 to separate from the socket, allowing it to be pulled out and moved. This will move the connecting post 502, causing the holding plate 2 to be pulled out. When it is pulled out to the maintenance position, releasing the arc plates 501 will reset the spring 504, causing the pin 503 to engage with the corresponding socket again, thus completing the positioning and preventing movement during maintenance, facilitating maintenance. It can also be pulled out as a whole to inspect the PCB board 3.

[0021] To improve the convenience of maintenance, a connecting rod 7 is provided between the limiting plate 4 and the fixed layer plate 1 above. The telescopic rod 6 is composed of multiple telescopic sleeves that are interlocked. The top and bottom telescopic sleeves are fixed to the fixed layer plate 1 and the limiting plate 4, respectively. The limiting plate 4 has a long groove. One end of the connecting rod 7 is inside the long groove. The two ends of the connecting rod 7 are hinged to the holding plate 2 and the fixed layer plate 1, respectively.

[0022] Working principle: When the holding plate 2 is constrained, the connecting rod 7 is also constrained, so the telescopic rod 6 will not extend or retract, thus achieving stability. When the holding plate 2 is pulled out and moved, the connecting rod 7 moves, causing the spacing to change, which in turn causes the telescopic rod 6 to extend, expanding the space at the top of the PCB board 3, further facilitating maintenance.

[0023] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
