Description

Technical Field

[0001] The utility model relates to the technical field of circuit board installation, in particular to a printed circuit board. Background Art

[0002] A printed circuit board, also known as a printed circuit board, is a provider of electrical connections for electronic components. Printed circuit boards are often represented by "PCB" instead of PCB boards. Existing printed circuit boards have round openings at the four corners, and metal rings are wrapped around the inside of the round openings. The circuit boards are fixed with screws, and the installation and removal of the screws require tools. Over time, the screws are prone to loosening, and the circuit boards become loose as well.

[0003] After searching, the Chinese patent publication number CN214481876U discloses a printed circuit board that is easy to install and disassemble, which relates to the technical field of circuit boards and solves the problem that the existing printed circuit boards use screws to fix the circuit boards, the installation and removal of the screws require the help of tools, and the screws are prone to loosening over time. The key points of its technical solution are that it includes a mounting plate, the circuit board is located on the top of the mounting plate, and a plurality of fixing cylinders are fixedly connected to the bottom of the mounting plate. The inner cavity of the fixing cylinder is plugged with a fixing mechanism, and the bottom of the mounting plate is provided with an unlocking mechanism for unlocking the fixing mechanism. The effect is that when the circuit board needs to be fixed, the circuit board is placed on the top of the mounting plate, so that the insertion rod passes through the circular opening and the fixing cylinder on the circuit board. After the card block passes through the fixing cylinder, the circuit board can be firmly fixed. If the circuit board needs to be disassembled, it only needs to push the connecting plate in the direction of the fixing cylinder so that the pressing cylinder squeezes the card block, and the insertion rod is separated from the fixing cylinder.

[0004] The above patent has extremely high requirements for the installation environment of the circuit board in actual application. The installation environment needs to meet the overall accommodation space of the installation board, while the actual installation environment of the PCB circuit board is mostly relatively narrow, which will lead to the problem of low applicability of the above-mentioned printed circuit board. At the same time, according to the update of existing installation methods, some fields have gradually replaced the traditional installation method with magnetic installation, and for the installation of PCB circuit boards, it is necessary to ensure the stability of its installation. Although the single magnetic installation can solve the problems of inconvenient disassembly and environmental space, it lacks stability and is temporarily not suitable for the installation of PCB circuit boards. In view of this, we propose a printed circuit board. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a printed circuit board, which solves the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A printed circuit board comprises a circuit board body and a pre-plug pin for positioning the circuit board body, wherein the circuit board body is provided with a mounting plate, and two magnetic seats are symmetrically arranged on the mounting plate, and the two magnetic seats are connected with limiting ring sleeves, and the inner wall surface of the magnetic seat is magnetically connected to the axial surface of the pre-plug pin.

[0008] Preferably, a limiting block is fixedly connected to the magnetic seat, and a right-angle groove for the limiting block to slide is provided in the limiting ring sleeve.

[0009] Preferably, a magnet is fixedly connected inside the right-angle groove, and the right-angle groove is magnetically connected to the surface of the limit block through the magnet.

[0010] Preferably, the pre-plug is composed of a plug rod and a plug cap combination, the surface of the plug rod is fixedly connected with a magnetic ring, the inner ring surface of the magnetic seat is fixedly connected with a magnetic ring, and the surface of the plug rod is magnetically connected to the inner wall surface of the magnetic seat through the magnetic ring.

[0011] Preferably, the magnetic poles of the magnetic ring and the magnetic circle facing each other are the same.

[0012] Preferably, a plug hole is provided inside the mounting plate, and a chamfer is provided at the bottom end of the plug hole.

[0013] By means of the above technical solution, the utility model provides a printed circuit board.

[0014] Beneficial effects:

[0015] (1) The printed circuit board combines the traditional plug-in, clip-on and sleeve connection methods with the magnetic connection method by setting a magnetic base to initially connect with the pre-pin and then setting a limit ring sleeve, so as to achieve stable fixation and quick installation at the same time, solve the problem that the traditional screw installation and removal require the help of tools, and at the same time minimize the restrictions on the installation environment requirements, and occupy a small installation area, so as to achieve the purpose of improving the applicability and practicality of the circuit board body installation.

[0016] (2) This printed circuit board achieves height limitation of the limit ring sleeve by setting a limit block and a right-angle groove on the limit ring sleeve, and combines the magnetic adsorption of the magnet to achieve the purpose of stable fixation of the limit ring sleeve. The limit ring sleeve bundles the two magnetic seats to avoid separation of the two magnetic seats. The combined magnetic seats are just stuck at the bottom of the plug cap and are limited in height by the plug cap, thereby achieving a stable fixation effect. The traditional plug-in, card-connection, and sleeve connection methods are combined with the magnetic connection method to achieve stable fixation while achieving the purpose of quick installation.

[0017] (3) This printed circuit board has a magnetic ring and a magnetic circle with the same magnetic poles on the opposite side. When the magnetic poles are the same, the inner wall surface of the magnetic ring and the outer surface of the magnetic circle will generate magnetic repulsion. When installing the circuit board body, it is necessary to manually merge the two magnetic seats before inserting the limiting ring sleeve. When disassembling the circuit board body, after pulling out the limiting ring sleeve, the two magnetic seats can be quickly separated by using the magnetic repulsion generated by the magnetic ring and the magnetic circle. At this time, only the circuit board body needs to be pulled out to achieve the effect of rapid disassembly, thereby achieving the purpose of rapid installation and disassembly.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-Figure 6 , a technical solution provided by the utility model:

[0029] A printed circuit board comprises a circuit board body 1 and a pre-plug pin 2 for positioning the circuit board body 1. The pre-plug pin 2 is pre-installed at a location where the printed circuit board body 1 needs to be installed. A plurality of mounting plates 3 are fixedly connected to the circuit board body 1. Two symmetrically distributed magnetic seats 4 are slidably connected to the mounting plates 3. The two magnetic seats 4 are combined and sleeved with a limiting ring sleeve 5. The inner wall surface of the magnetic seat 4 is magnetically connected to the axial surface of the pre-plug pin 2. The pre-plug pin 2 is composed of a plug rod 21 and a plug cap 22. The diameter of the plug cap 22 is larger than the diameter of the plug rod 21 and is used to limit the height of the positioned magnetic seat 4. A magnetic ring 23 is fixedly connected to the surface of the plug rod 21. A magnetic ring 41 is fixedly connected to the inner ring surface of the magnetic seat 4. The surface of the plug rod 21 is magnetically connected to the inner wall surface of the magnetic seat 4 through the magnetic ring 23. A socket 8 is provided inside the mounting plate 3. A guide angle 9 is provided at the bottom end of the socket 8. The guide angle 9 is in an inclined state and can guide the insertion of the pre-plug pin 2. The traditional plug-in, clip-on and socket-on methods are combined with the magnetic connection method to achieve stable fixation and quick installation, solving the problem that traditional screw installation and removal require tools. At the same time, it also minimizes the restrictions on the installation environment requirements and occupies a small installation area, which can achieve the purpose of improving the installation applicability and practicality of the circuit board body 1.

[0030] In this embodiment, the magnetic seat 4 is fixedly connected with a limit block 6, and the limit block 6 is set to be made of metal material. A right-angle groove 7 for the limit block 6 to slide is opened in the limit ring sleeve 5. The right-angle groove 7 is composed of a combination of a vertical groove and a horizontal groove. A magnet is fixedly connected to the innermost end of the horizontal groove, and the right-angle groove 7 is magnetically connected to the surface of the limit block 6 through the magnet. By setting the limit block 6 and the right-angle groove 7 on the limit ring sleeve 5, the height of the limit ring sleeve 5 is limited, and the purpose of stable fixation of the limit ring sleeve 5 is achieved by combining the magnetic adsorption of the magnet, and the limit ring sleeve 5 is bundled with the two magnetic seats 4 to avoid the separation of the two magnetic seats 4. The combined magnetic seat 4 is just stuck at the bottom of the plug cap 22, and the height is limited by the plug cap 22, thereby achieving the effect of stable fixation, combining the traditional plug-in, card-connection, and sleeve connection methods with the magnetic connection method, achieving stable fixation while achieving the purpose of rapid installation.

[0031] Furthermore, the magnetic poles of the magnetic ring 41 and the magnetic circle 23 are opposite. When the magnetic poles are opposite, the inner wall surface of the magnetic ring 41 and the outer surface of the magnetic circle 23 will generate magnetic attraction. When the circuit board body 1 is installed, the two magnetic seats 4 can be automatically adsorbed on the surface of the pre-pin 2 to achieve quick installation. When the circuit board body 1 is disassembled, after pulling out the limit ring sleeve 5, it is necessary to manually pull out the two magnetic seats 4 and then pull out the circuit board body 1.

[0032] Example 2

[0033] The only difference between Example 2 and Example 1 is that the magnetic poles of the magnetic ring 41 and the magnetic circle 23 are the same. When the magnetic poles are the same, the inner wall surface of the magnetic ring 41 and the outer surface of the magnetic circle 23 will generate magnetic repulsion. When installing the circuit board body 1, it is necessary to manually merge the two magnetic seats 4 before inserting the limiting ring sleeve 5. When disassembling the circuit board body 1, after pulling out the limiting ring sleeve 5, the two magnetic seats 4 can be quickly separated by using the magnetic repulsion generated by the magnetic ring 41 and the magnetic circle 23. At this time, only the circuit board body 1 needs to be pulled out to achieve the effect of quick disassembly, thereby achieving the purpose of quick installation and disassembly. Compared with the scheme with opposite magnetic poles in Example 1, the convenience of installation is not as good as Example 1, but the convenience of disassembly is worse than Example 1.

[0034] When a printed circuit board of the utility model is in use, embodiment 2 is used as a preferred embodiment of the present technical solution. The pre-plug 2 is pre-installed at the place where the printed circuit board body 1 needs to be installed. The two magnetic seats 4 are in a relatively distant state in the initial state. When the circuit board body 1 needs to be installed, the plug hole 8 in the mounting plate 3 on the circuit board body 1 is aligned with the pre-plug 2 and inserted. After the pre-plug 2 is inserted, the magnetic ring 23 and the magnetic ring 41 are in the same horizontal plane. At this time, the magnetic ring 23 generates a magnetic repulsion force on the magnetic ring 41, and the operator needs to manually squeeze the two magnetic seats 4 to make it The top of the magnetic seat 4 is just inserted into the bottom of the plug cap 22 at this time, and the plug cap 22 has a height limiting effect on it. At this time, the limiting ring sleeve 5 is inserted. During the installation of the limiting ring sleeve 5, it is necessary to align the bottom end opening of the right-angle groove 7 on the limiting ring sleeve 5 with the limiting block 6. After alignment, the limiting ring sleeve 5 can be installed on the outer surfaces of the two magnetic seats 4. After the installation, the limiting ring sleeve 5 is rotated so that the transverse groove area at the top of the right-angle groove 7 rotates on the limiting block 6. After rotation, the inner wall surface of the transverse groove area is magnetically connected to the limiting block 6. The connection effect is as follows Figure 1 As shown in , the limit block 6 is now located in the innermost area of ​​the transverse groove, thereby limiting the height of the limit ring sleeve 5, and combining with the magnetic adsorption of the magnet to achieve the purpose of stably fixing the limit ring sleeve 5, and the limit ring sleeve 5 bundles the two magnetic seats 4 to avoid the separation of the two magnetic seats 4. The merged magnetic seat 4 is just stuck at the bottom of the plug cap 22, and the height is limited by the plug cap 22, thereby achieving a stable fixation effect, combining the traditional plug-in, card-connection, and sleeve connection methods with the magnetic connection method, achieving stable fixation while achieving the purpose of quick installation, solving the problem that traditional screw installation and disassembly require the use of tools, and at the same time minimizing the restrictions on the installation environment requirements. The technical solution occupies a small installation area, which can achieve the purpose of improving the installation applicability and practicality of the circuit board body 1.

[0035] At the same time, when the circuit board body 1 needs to be disassembled, the operator only needs to reverse the limit ring sleeve 5 and then pull out the limit ring sleeve 5 upwards. After pulling out the limit ring sleeve 5, the two magnetic seats 4 can use the magnetic repulsion generated by the magnetic ring 41 and the magnetic circle 23 to quickly separate. At this time, only the circuit board body 1 needs to be pulled out to achieve the effect of quick disassembly and achieve the purpose of quick installation and disassembly. A new installation method is adopted to combine the traditional method with the magnetic installation method to solve the problems of inconvenient installation and disassembly, large space occupied, and unstable installation.
