Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, in particular to an LED module substrate. Background Art

[0002] As early as 1962, the United States invented LED lights. With the different degrees of exploration of LED in various countries later, LEDs have now been widely integrated into people's lives. For example, they can be installed on the doorheads of large shopping malls to introduce and promote different products; installed on the performers' stage to bring an immersive sense of shock to the audience; installed on the walls of subway stations to show passengers directions. However, in order to make the LED screen light up in various colors and achieve the desired effect, it is also necessary to install LED modules behind the LED screen, and connect the cables, power supply and control card to make the LED screen display the effects people want to present.

[0003] LED modules are very important parts in the use of LED screens. LED modules are composed of LED light points, components, PCB circuit boards, shells and packaging materials. During the installation process, the LED light points are encapsulated in a matrix with resin or plastic, and then the components are arranged and combined and welded on the PCB circuit board, and the PCB circuit board is fixed to the main body of the substrate with screws. It is encapsulated with packaging materials such as silicone, epoxy resin or glass with good heat resistance, temperature resistance and corrosion resistance, and then the shell is installed to protect the PCB circuit board from mechanical and environmental damage. When the LED modules are combined into a large LED screen, align the arrows between each module and connect each module in series with wires such as cables and power supplies to complete the installation.

[0004] However, during the installation of the above-mentioned LED module, since many screws need to be fixed between the PCB circuit board and the substrate body, it is necessary to align the screw holes between the PCB circuit board and the substrate body before installation, and keep the positions of the screw holes unchanged during the process of tightening the screws. When the PCB circuit board is damaged during use and needs to be replaced, the fixed place needs to be loosened with a screwdriver. After replacing the intact PCB circuit board, the screws need to be tightened again. This process is time-consuming and inconvenient, so an LED module substrate that is easy to replace and install is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an LED module substrate to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an LED module substrate comprises a substrate body and a PCB circuit board, characterized in that: a PCB circuit board groove for installing the PCB circuit board is expanded on the inner wall of the substrate body, and spring grooves are symmetrically provided on both sides of the inner wall of the PCB circuit board groove, and a baffle groove is provided in the middle of the inner wall of the PCB circuit board groove, a power plug is symmetrically installed at the middle position of the lower end of the PCB circuit board, and a cable plug is symmetrically installed at the side position of the power plug, and a circuit board spring is symmetrically installed on the side of the lower end of the PCB circuit board, a power jack is provided on the inner wall of the PCB circuit board, and a cable jack is symmetrically provided on the side of the power jack, and circuit board spring grooves are provided on both sides of the inner wall of the PCB circuit board groove, limiting columns are symmetrically installed on the inner wall of the substrate body, and a pull rod is symmetrically installed on the outer wall of the substrate body, and a limiting block is installed in the middle position of the pull rod, and a baffle is rotatably installed on the end of the pull rod, and a spring is symmetrically installed on the inner wall of the baffle.

[0007] By adopting the above technical scheme, by providing a substrate body and a PCB circuit board, when installing the PCB circuit board, the baffle is pulled into the baffle groove. At this time, the spring inside the baffle groove is squeezed in the spring groove. Under the cooperation of the limit block and the limit column, the position of the baffle is limited, so that the PCB circuit board can be directly placed in the PCB circuit board groove. At the same time, during the placement of the PCB circuit board, the cable plug and the power plug at the bottom of the PCB circuit board can be directly inserted into the cable jack and the power jack on the substrate body, thereby avoiding the occurrence of incorrect connection between wires. After the PCB circuit board is installed, the pull rod can be directly rotated to make the spring lose its restriction. At this time, the baffle is reset under the action of the spring, and the position of the PCB circuit board is limited, so that the PCB circuit board and the substrate body will not be easily separated, thereby achieving the effect of convenient installation.

[0008] The utility model is further configured such that the spring groove provided on the inner wall of the PCB circuit board groove corresponds to the position of the spring, and the baffle groove corresponds to the position of the baffle, and the spring groove and the baffle groove are connected to each other.

[0009] By adopting the above technical solution, the spring can slide and squeeze in the spring groove 601, so that when the pull rod moves the baffle toward the inside of the PCB circuit board groove, the baffle will move in the baffle groove without being skewed, so that the baffle will not be restricted by the spring groove when entering the baffle groove.

[0010] The utility model is further configured such that the power plug installed at the lower end of the PCB circuit board corresponds to the position of the power jack, the cable plug corresponds to the position of the cable jack, and the circuit board spring corresponds to the position of the circuit board spring slot.

[0011] By adopting the above technical solution, when installing the PCB circuit board, after aligning the PCB circuit board with the PCB circuit board slot, the PCB circuit board is directly placed inside the PCB circuit board slot, so that the cable plug can be inserted into the cable jack, and the power plug can be inserted into the power jack at the same time, and at the same time, the circuit board spring is squeezed in the circuit board spring slot.

[0012] The utility model is further configured that two groups of the limit posts are symmetrically installed.

[0013] By adopting the above technical solution, when the pull rod is pulled, the limit block touches the limit column. At this time, the pull rod is rotated 90° so that the pull rod can continue to be pulled. After the baffle is completely pulled into the baffle groove, the pull rod is rotated 90° again. The limit column can smoothly limit the position of the limit block, so that the position of the baffle is limited by the limit block.

[0014] The utility model is further configured such that the length of the baffle is equal to the length of the PCB circuit board.

[0015] By adopting the above technical solution, when the baffle is fixing the PCB circuit board, accidents caused by the circuit board spring using its characteristics to lift up the edge of the PCB circuit board can be avoided, thereby ensuring that the baffle can fix the PCB circuit board.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] The utility model is provided with a substrate body and a PCB circuit board, so that when the PCB circuit board is installed, the baffle is pulled into the baffle groove, and the spring inside the baffle groove is squeezed in the spring groove. Under the cooperation of the limit block and the limit column, the position of the baffle is restricted, so that the PCB circuit board can be directly placed in the PCB circuit board groove. At the same time, during the placement of the PCB circuit board, the cable plug and the power plug at the bottom of the PCB circuit board can be directly inserted into the cable jack and the power jack on the substrate body, thereby avoiding the occurrence of incorrect connection between wires. After the PCB circuit board is installed, the pull rod can be directly rotated to make the spring lose its restriction. At this time, the baffle is reset under the action of the spring, and the position of the PCB circuit board is restricted, so that the PCB circuit board and the substrate body will not be easily separated, thereby achieving the effect of convenient installation.

DETAILED DESCRIPTION

[0023] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] An LED module substrate, such as Figure 1 - Figure 4 As shown, a substrate body 1 and a PCB circuit board 2.

[0026] Specifically, the outer wall of the substrate body 1 is symmetrically installed with a pull rod 4, and the end of the pull rod 4 is rotatably installed with a baffle 5, so that when the pull rod 4 is pulled to both ends, the baffle 5 will move into the baffle groove 501, and when the baffle 5 moves into the baffle groove 501, it will drive the spring 6 to be squeezed into the spring groove 601 at the same time. Since the limiting column 3 is installed inside the substrate body 1, when the pull rod 4 is pulled to both sides, the limiting block 401 will touch the limiting column 3, so that the pull rod 4 cannot be pulled further. At this time, the pull rod 4 is rotated 90°, so that the position of the limiting block 401 and the limiting column 3 are staggered, so that the pull rod 4 can continue to be pulled to both sides. When the baffle 5 completely enters the baffle groove 501, the pull rod 4 is rotated 90° again, so that the limiting block 401 is limited by the position of the limiting column 3. , so that the position of the baffle 5 is restricted by the limit block 401. At this time, after the circuit board spring 203 at the bottom of the PCB circuit board 2 loses the restriction of the baffle 5, the circuit board spring 203 will use its own characteristics to push the PCB circuit board 2 upward. At the same time, the cable jack 102 and the power jack 103 opened in the PCB circuit board slot 101 will be separated from the cable plug 201 and the power plug 202. At this time, the PCB circuit board 2 can be easily removed. When installing the PCB circuit board 2, it is only necessary to pull the pull rod 4 at both ends so that the pull rod 4 drives the baffle 5 to move into the baffle slot 501. When the pull rod 4 moves into the baffle slot 501, it drives the spring 6 to squeeze into the spring slot 601. In the process of pulling the pull rod 4, due to the main A limiting column 3 is installed inside the body 1, so that the limiting block 401 will be blocked by the limiting column 3. At this time, the pull rod 4 is rotated 90° to make the limiting block 401 staggered with the limiting column 3, so that the pull rod 4 can continue to be pulled. When the baffle 5 completely enters the baffle groove 501, the pull rod 4 is rotated 90° again. At this time, the position of the limiting block 401 will be limited by the limiting column 3. At the same time, the position of the baffle 5 is limited by the limiting block 401, so that the PCB circuit board 2 can be placed above the PCB circuit board groove 101. When the position of the PCB circuit board 2 is aligned with the position of the PCB circuit board groove 101, the position of the cable plug 201 at its bottom will be aligned with the position of the cable jack 102, so that the position of the power plug 202 will be aligned with the power jack 10 3, and the position of the circuit board spring 203 is aligned with the position of the circuit board spring slot 104. When the PCB circuit board 2 is installed into the PCB circuit board slot 101, the power plug 202 is inserted into the power jack 103, and the cable plug 201 is inserted into the cable jack 102. At the same time, the circuit board spring 203 is squeezed into the circuit board spring slot 104. When the PCB circuit board 2 enters the PCB circuit board slot 101, the pull rod 4 is rotated 90°, so that the position of the limit block 401 is staggered with the limit column 3, so that the limit block 401 loses the restriction of the limit column 3, so that the spring 6, under the action of its characteristics, pushes the baffle 5 out of the baffle slot 501, so that the circuit board spring 203 is restricted under its action.The installation of the PCB circuit board 2 is completed. Under the action of the baffle 5 and the circuit board spring 203, the PCB circuit board 2 will not be easily separated from the substrate body 1, achieving a fixing effect.

[0027] See also Figure 2 The spring groove 601 opened on the inner wall of the PCB circuit board slot 101 corresponds to the position of the spring 6, so that the spring 6 can slide and be squeezed in the spring groove 601, and the baffle groove 501 corresponds to the position of the baffle 5, so that when the pull rod 4 moves the baffle 5 into the PCB circuit board slot 101, the baffle 5 will move in the baffle groove 501 without being skewed, and the spring groove 601 and the baffle groove 501 are connected to each other, so that the baffle 5 is not restricted by the spring groove 601 when entering the baffle groove 501.

[0028] See also Figure 1 The power plug 202 installed at the lower end of the PCB circuit board 2 corresponds to the position of the power jack 103, and the cable plug 201 corresponds to the position of the cable jack 102, and the circuit board spring 203 corresponds to the position of the circuit board spring slot 104, so that when the PCB circuit board 2 is installed, after the PCB circuit board 2 is aligned with the PCB circuit board slot 101, the PCB circuit board 2 is directly placed inside the PCB circuit board slot 101, so that the cable plug 201 can be inserted into the cable jack 102, and the power plug 202 can be inserted into the power jack 103 at the same time, and at the same time the circuit board spring 203 is squeezed in the circuit board spring slot 104.

[0029] See also Figure 2 There are two groups of limit columns 3 symmetrically installed, so that when the pull rod 4 is pulled, the limit block 401 touches the limit column 3. At this time, the pull rod 4 is rotated 90° so that the pull rod 4 can continue to be pulled. After the baffle 5 is completely pulled into the baffle groove 501, the pull rod 4 is rotated 90° again. The limit column 3 can smoothly limit the position of the limit block 401, so that the position of the baffle 5 is limited by the limit block 401.

[0030] See also Figure 2 The length of the baffle 5 is equal to the length of the PCB circuit board 2, so that when the baffle 5 fixes the PCB circuit board 2, it can avoid accidents caused by the circuit board spring 203 using its characteristics to lift the edge of the PCB circuit board 2, thereby ensuring that the baffle 5 can fix the PCB circuit board 2.

[0031] The working principle of the utility model is as follows: by pulling the pull rod 4 to both sides, the baffle 5 moves into the baffle groove 501. During the pulling process of the pull rod 4, the springs 6 on both sides of the inner wall of the baffle 5 will be squeezed into the spring groove 601, and the limit block 401 will touch the limit column 3. At this time, the pull rod 4 is rotated 90° to make the position of the limit block 401 and the limit column 3 staggered, so that the pull rod 4 can continue to be pulled. When the baffle 5 completely enters the baffle groove 501, the pull rod 4 is rotated 90° again to stop the limit column 3. The position of the limit block 401 will be restricted, so that the position of the baffle 5 is restricted, so that the baffle 5 will not be reset by the spring 6. At this time, the circuit board spring 203 at the bottom of the PCB circuit board 2 loses the restriction of the baffle 5, thereby pushing the PCB circuit board 2 upward. At the same time, under the action of the circuit board spring 203, the cable jack 102 and the power jack 103 will also be separated from the cable plug 201 and the power plug 202 on the substrate body 1, so that the damaged PCB circuit board 2 can be removed.
