Description

Technical Field

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

[0002] An integrated circuit board includes a board body and integrated circuit chips mounted on the board body. However, the board body of commonly used integrated circuit boards is fixed by a cross-shaped bracket. This cross-shaped bracket cannot fix circuit boards of different thicknesses, which narrows the scope of application. Moreover, the assembled circuit board is not convenient for position adjustment during later installation and use.

[0003] For example, CN218603718U discloses a modular integrated circuit board, which includes multiple main circuit boards and an insulating cross. The multiple main circuit boards are distributed around the insulating cross by a connecting group. The connecting group includes multiple slots set inside the insulating cross. Each main circuit board has multiple metal contacts at the edge position where it contacts the insulating cross. The slots have metal springs that contact the metal contacts in sequence. One end of the metal springs is connected to a pin. The upper and lower sides of the outer end of the insulating cross have limiting grooves. The outer end of the insulating cross has a U-shaped limiting sleeve that covers the limiting groove. The outer end of the insulating cross is fixed to the corresponding U-shaped limiting sleeve by longitudinally arranged bolts.

[0004] As can be seen from the above-disclosed scheme, the circuit board body is installed and fixed by an insulating cross. However, the slot width of the insulating cross is fixed, which makes it unsuitable for fixing circuit board bodies of different thicknesses, thus narrowing the scope of application. In addition, the insulating cross is relatively large, which also makes the support height of the assembled circuit board body fixed. This will cause some inconvenience to the installation of the assembled circuit board when it needs to be installed and used later. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a modular integrated circuit board. This modular integrated circuit board, through the setting of a fixed cross plate, a movable cross plate, and a pressing seat, facilitates the rapid assembly of the circuit board body. At the same time, the pressing position can be adjusted according to the different thicknesses of the circuit board body, increasing the applicability. Furthermore, the fixed cross plate, movable cross plate, and support frame are not only small in size, but also allow for adjustment of the support height of the circuit board, greatly improving the convenience of its subsequent use and installation.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A modular integrated circuit board includes four circuit board bodies and four fixed cross plates. The surfaces of all four circuit board bodies are in contact with and pressed against the bottom surface of the fixed cross plates. A support frame is fixedly connected to the middle of the fixed cross plates. One end of the support frame has a support rod, and one end of the support rod is threadedly connected to an adjusting rod. A pressing seat and a movable cross plate are slidably fitted onto the surface of the support frame. The surface of the movable cross plate is in contact with and pressed against the bottom of the circuit board body. Four pressing rods are fixedly connected to the surface of the pressing seat. One end of each pressing rod is in contact with and pressed against the bottom of the movable cross plate. A guide sleeve is fixedly fitted onto the bottom of the pressing seat, and one end of the guide sleeve is in contact with and pressed against a pressing nut. This modular integrated circuit board, with its fixed cross plates, movable cross plates, and pressing seats, facilitates rapid assembly of the circuit board bodies. It also allows for adjustment of the pressing position according to different thicknesses of the circuit board bodies, increasing its applicability. Furthermore, the fixed cross plates, movable cross plates, and support frame are not only compact but also allow for adjustment of the circuit board's support height, greatly improving the convenience of subsequent use and installation.

[0008] Furthermore, one end of the support rod is provided with a receiving hole, and the inner wall of the receiving hole is provided with an internal thread. The surface of the adjusting rod is provided with an external thread that matches the internal thread of the receiving hole. One end of the adjusting rod is fixedly connected to a fixing plate. The adjusting rod can be extended and retracted through the thread, thereby adjusting the support height of the support rod.

[0009] Furthermore, the support frame is cross-shaped, and a sliding hole is provided in the middle of the movable cross plate. The sliding hole is cross-shaped, which enables the movable cross plate to have a lifting function, making it easy to clamp circuit board bodies of different thicknesses.

[0010] Furthermore, one end of the guide sleeve is provided with a through hole, and the center of the extrusion seat is provided with a guide hole coaxial with the through hole. The inner diameter of the guide hole is larger than the outer diameter of the support rod, so that the extrusion seat can slide up and down on the surface of the support rod.

[0011] Furthermore, one end of the movable cross plate is provided with a protrusion, the surface of the protrusion is provided with a screw hole, and one end of the fixed cross plate is fitted with a screw, so as to facilitate the fastening of one end of the movable cross plate and the fixed cross plate, thereby clamping the assembled circuit board body.

[0012] Furthermore, a threaded hole is provided at the center of the compression nut, and the surface of the support rod is provided with an external thread that matches the internal thread of the threaded hole, so that the lifting height of the compression seat can be controlled by the compression nut.

[0013] Furthermore, the fixed cross plate, support frame, and movable cross plate are all made of insulating material.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution facilitates the rapid assembly of the circuit board body by setting a fixed cross plate, a movable cross plate and an extrusion seat. At the same time, the extrusion position can be adjusted according to the different thicknesses of the circuit board body, which increases the applicability.

[0016] (2) The fixed cross plate, movable cross plate and support frame set in this solution are not only small in size, but also can adjust the support height of the circuit board, which greatly improves the convenience of its later use and installation. Attached Figure Description

[0024] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5A modular integrated circuit board includes four circuit board bodies 1 and four fixed cross plates 2. The surfaces of all four circuit board bodies 1 are in contact with and pressed against the bottom surface of the fixed cross plates 2. A support frame 3 is fixedly connected to the middle position of the fixed cross plates 2. One end of the support frame 3 has a support rod 31, and one end of the support rod 31 is threadedly connected to an adjusting rod 32. A pressing seat 5 and a movable cross plate 4 are slidably sleeved on the surface of the support frame 3. The fixed cross plate 2, support frame 3, and movable cross plate 4 are all made of insulating material, which can prevent random electrical conduction between circuit boards. Compared with existing cross plates, the movable cross plate 4... The contact area between the fixed cross plate 2 and the circuit board body 1 is small, eliminating the need for metal bosses and reducing the production cost of the circuit board support. The surface of the movable cross plate 4 contacts and presses against the bottom of the circuit board body 1. Four pressing rods 51 are fixedly connected to the surface of the pressing seat 5. One end of the pressing rod 51 contacts and presses against the bottom of the movable cross plate 4. A guide sleeve 52 is fixedly sleeved at the bottom of the pressing seat 5. One end of the guide sleeve 52 contacts and presses against the pressing nut 6. A threaded hole is provided at the center of the pressing nut 6. The surface of the support rod 31 is provided with an external thread that matches the internal thread of the threaded hole. The lifting height of the pressing seat 5 can be controlled by the pressing nut 6.

[0027] One end of the support rod 31 is provided with a storage hole, and the inner wall of the storage hole is provided with an internal thread. The surface of the adjusting rod 32 is provided with an external thread that matches the internal thread of the storage hole. One end of the adjusting rod 32 is fixedly connected to a fixing plate 33. The adjusting rod 32 can be extended and retracted through the thread to adjust the support height of the support rod 31. The support frame 3 is cross-shaped. The movable cross plate 4 is provided with a sliding hole 43 in the middle position. The sliding hole 43 is cross-shaped, which makes the movable cross plate 4 have the function of lifting and lowering, which is convenient for clamping circuit board bodies 1 of different thicknesses.

[0028] One end of the guide sleeve 52 is provided with a through hole, and the center of the extrusion seat 5 is provided with a guide hole 53 coaxial with the through hole. The inner diameter of the guide hole 53 is larger than the outer diameter of the support rod 31, so that the extrusion seat 5 can slide up and down on the surface of the support rod 31. One end of the movable cross plate 4 is provided with a protrusion 41, and the surface of the protrusion 41 is provided with a screw hole 42. One end of the fixed cross plate 2 is fitted with a screw, which facilitates the fastening of one end of the movable cross plate 4 and the fixed cross plate 2, thereby clamping the assembled circuit board body 1.

[0029] During assembly, the four circuit board bodies 1 are first inserted into the clamping groove formed by the fixed cross plate 2, support frame 3, and movable cross plate 4. Then, the compression nut 6 is rotated counterclockwise with a wrench, causing the compression nut 6 to press towards the compression seat 5. This causes the compression rod 51 on the compression seat 5 to press against the movable cross plate 4, thereby clamping the circuit board body 1 between the movable cross plate 4 and the fixed cross plate 2. Finally, one end of the fixed cross plate 2 is threaded onto the protrusion 41 at one end of the movable cross plate 4, thus completing the assembly of the circuit board body 1. When the circuit board is installed on electrical machinery or other objects, the fixing plate 33 can be manually rotated counterclockwise to extend the adjusting rod 32 downwards, increasing the support height of the circuit board. The fixed cross plate 2, movable cross plate 4, and pressing seat 5 facilitate the rapid assembly of the circuit board body 1. At the same time, the pressing position can be adjusted according to the different thicknesses of the circuit board body 1, increasing the applicability. Furthermore, the fixed cross plate 2, movable cross plate 4, and support frame 3 are not only small in size but also allow for adjustment of the support height of the circuit board, greatly improving the convenience of its later use and installation.

[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
