Description

Technical Field

[0001] This utility model relates to the field of optocoupler technology, specifically a structure for convenient installation of optocoupler devices. Background Technology

[0002] An optocoupler is an electro-optical-electrical conversion device that transmits electrical signals using light as a medium. It consists of two parts: a light source and a light receiver. The light source and light receiver are assembled in the same sealed housing and isolated from each other by a transparent insulator. The pins of the light source are the input terminals, and the pins of the light receiver are the output terminals. Common light sources include light-emitting diodes (LEDs), and common light receivers include photodiodes, phototransistors, etc.

[0003] Currently, when installing optocouplers on PCB circuit boards, tweezers are often used to hold the optocouplers for positioning and installation. However, since optocouplers require precise installation and positioning, using tweezers can easily cause positional shifts during installation, resulting in incorrect optocoupler installation and affecting subsequent normal use.

[0004] Therefore, a structure that can be stably positioned for easy installation of optocouplers is needed. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a structure for convenient installation of optocouplers, which can adapt to different optocoupler sizes, ensure accurate positioning during installation, improve stability, and prevent incorrect installation positions.

[0006] To achieve the above objectives, the present invention proposes the following specific solutions:

[0007] A structure for convenient installation of optocouplers includes a positioning frame, a support plate fixed to one outer wall of the positioning frame, a fixing plate fixed to one upper side wall of the support plate, a threaded hole on the edge of the fixing plate, a screw threaded into the threaded hole, a rotating rod fixed to the lower end of the screw, a rotating disk fixed to the lower end of the rotating rod, a movable frame above the positioning frame, a C-shaped frame fixed to one outer wall of the movable frame, the support plate penetrating the C-shaped frame, a movable plate fixed to one outer wall of the C-shaped frame, a through hole in the middle of the movable plate, the rotating rod penetrating the through hole, symmetrical connecting grooves on the inner wall of the movable frame, symmetrical clamping plates on the inner side of the movable frame, a connecting plate fixed to the middle of one side wall of the clamping plate, the connecting plate penetrating the connecting groove, a first spring fixed to one side wall of the clamping plate, the first spring located outside the connecting plate, and one end of the first spring fixed to the inner wall of the movable frame.

[0008] As a preferred structural solution of this utility model for convenient installation of optocouplers, a rectangular groove is provided in the middle of the clamping plate, and a rectangular rod is movably inserted into the inner side of the rectangular groove, the rectangular rod passing through the rectangular groove.

[0009] As a preferred structural solution of this utility model for convenient installation of optocouplers, a positioning plate is fixed at the lower end of the rectangular rod, and a fixing block is fixed at the top end of the rectangular rod.

[0010] As a preferred structural solution of this utility model for convenient installation of optocouplers, a second spring is fixed to the bottom surface of the fixing block. The second spring is located outside the rectangular rod, and the lower end of the second spring is fixed to the top surface of the clamping plate.

[0011] As a preferred structural solution of this utility model for convenient installation of optocouplers, a fixing plate is fixed at one end of the connecting plate, and the fixing plate is located outside the movable frame.

[0012] As a preferred structural solution of this utility model for convenient installation of optocouplers, a support pad is fixed to the bottom surface of the positioning frame, and an anti-slip strip is fixed to the other side wall of the clamping plate.

[0013] As a preferred structural solution of this utility model for convenient installation of optocouplers, multiple support pads and anti-slip strips are provided.

[0014] As a preferred structural solution of this utility model for convenient installation of optocouplers, both the support pad and the anti-slip strip are made of flexible materials.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention uses two clamping plates inside a movable frame to hold and fix the optocoupler. Two first springs can extend and retract as the two clamping plates move. When the optocoupler is located between the two clamping plates, the elastic force of the two first springs can push the two clamping plates to move and clamp and fix the optocoupler. By placing the positioning frame on the PCB circuit board at the position where the optocoupler needs to be installed, rotating the screw causes the screw to rotate and move downward inside the threaded hole on the fixing plate, which can drive the movable frame to move downward. The movable frame drives the optocoupler, which is clamped and fixed by the clamping plates, to move downward, so that it contacts the PCB circuit board for installation. This ensures that the optocoupler will not move during the installation process and can avoid the optocoupler from shifting during installation.

[0017] In this invention, the positioning frame is placed at a suitable position on the PCB circuit board, and after the two clamping plates clamp and fix the optocoupler, pressing the two fixing blocks causes the two rectangular rods to move downwards. As the two second springs are compressed, the two positioning plates can move downwards to contact the PCB circuit board. Since the two positioning plates are located below the two clamping plates, after the two clamping plates clamp the optocoupler, the two positioning plates are located on both sides of the optocoupler. By having the two positioning plates contact the PCB circuit board first, the position of the optocoupler can be accurately determined in advance, which can greatly improve the accuracy of optocoupler installation.

[0027] 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 scope of protection of the present utility model. Example 1

[0028] Please see Figure 1-7 As shown, this utility model provides the following technical solution: a structure for convenient installation of optocouplers, including a positioning frame 1, with a support pad 11 fixed on the bottom surface of the positioning frame 1. The support pad 11, made of flexible material, ensures that the positioning frame 1 will not damage the structure of the PCB circuit board when placed on it. The positioning frame 1 can be placed on the PCB circuit board at the position where the optocoupler needs to be installed, thus achieving positioning of the optocoupler before installation.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, specifically, the inner wall of the movable frame 2 is symmetrically provided with connecting grooves 22 for connecting the connecting plate 32, allowing the connecting plate 32 to move. The inner side of the movable frame 2 is symmetrically provided with clamping plates 3 for clamping and fixing the optocoupler. A connecting plate 32 is fixed to the middle of one side wall of the clamping plate 3 for support. The connecting plate 32 passes through the connecting groove 22. A first spring 33 is fixed to one side wall of the clamping plate 3. The first spring 33 can control the position of the clamping plate 3 by extension and retraction, clamping optocouplers of different sizes. The first spring 33 is located outside the connecting plate 32, with one end fixed to the inner wall of the movable frame 2. One end of the connecting plate 32 is fixed to a fixed... The fixed plate 321 prevents the connecting plate 32 from detaching from the inner side of the connecting groove 22. The fixed plate 321 is located on the outer side of the moving frame 2. The other side wall of the clamping plate 3 is fixed with an anti-slip strip 31 to increase friction and ensure the stability of the optocoupler clamping, thus avoiding damage to the optocoupler. Multiple support pads 11 and anti-slip strips 31 are provided. Both support pads 11 and anti-slip strips 31 are made of flexible material. This solution clamps and fixes the optocoupler with two clamping plates 3. The elastic extension and contraction capacity of the two first springs 33 ensures that the distance between the two clamping plates 3 can be adjusted, thereby clamping and fixing optocouplers of different sizes and enhancing applicability. Example 2

[0030] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, specifically, a support plate 12 is fixed to one outer wall of the positioning frame 1 to fix and support the fixed plate 121 and maintain the stability of the moving frame 2. A fixed plate 121 is fixed to one side wall of the support plate 12 to support the screw 13. The fixed plate 121 has a threaded hole 122 on its edge for the rotation and downward movement of the screw 13. The screw 13 is threaded inside the threaded hole 122, which can drive the moving plate 211 to move downward. A rotating rod 131 is fixed to the lower end of the screw 13. The rotating rod 131 rotates inside the through hole 212 to prevent the screw 13 from driving the moving plate 211 to rotate. A rotating disk 132 is fixed to the lower end of the rotating rod 131 to prevent the rotating rod 131 from disengaging from the inside of the through hole 212. A moving frame 2 is provided above the positioning frame 1 to drive the optocoupler to move. A C-shaped frame 21 is fixed to one outer wall, which can drive the movable frame 2 to move and keep the movable frame 2 stable. The support plate 12 passes through the C-shaped frame 21. A movable plate 211 is fixed to one outer wall of the C-shaped frame 21, which can drive the C-shaped frame 21 to move. The movable plate 211 has a through hole 212 in the middle for connecting and rotating the rotating rod 131. The rotating rod 131 passes through the through hole 212. In this solution, the screw 13 rotates and moves down inside the threaded hole 122, which drives the movable plate 211 to move down. The movable plate 211 drives the C-shaped frame 21 to move down, and the C-shaped frame 21 drives the movable frame 2 to move down. The movable frame 2 can drive the optocoupler held by the two clamping plates 3 to move down to contact the PCB circuit board, which facilitates the installation of the optocoupler and can keep the position of the optocoupler from shifting, thus enhancing the stability of the installation process. Example 3

[0031] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, specifically, the clamping plate 3 has a rectangular groove 34 in the middle for the vertical movement of the rectangular rod 35. The rectangular rod 35 is movably inserted into the inner side of the rectangular groove 34 to fix the positioning plate 351 and drive the positioning plate 351 to move up and down. The rectangular rod 35 passes through the rectangular groove 34, and the positioning plate 351 is fixed at the lower end of the rectangular rod 35 to accurately position the installation position of the optocoupler. A fixing block 352 is fixed at the top of the rectangular rod 35 for connecting the second spring 36. The second spring 36 is fixed at the bottom surface of the fixing block 352. The elastic tension of the second spring 36 can ensure that the positioning plate 351 is not interfered with by external forces. The second spring 36 automatically moves downward, located outside the rectangular rod 35. The lower end of the second spring 36 is fixed to the top surface of the clamping plate 3. In this scheme, the positioning frame 1 is placed on the PCB circuit board at the installation position of the optocoupler. After the two clamping plates 3 clamp and fix the optocoupler, the two positioning plates 351 are located on both sides of the optocoupler. By pressing the two fixing blocks 352, the two second springs 36 are contracted and the two rectangular rods 35 move downward, thereby driving the two positioning plates 351 to move downward and contact the PCB circuit board, further determining the installation position of the optocoupler and ensuring the accuracy of the optocoupler installation.

[0032] The working principle and usage process of this utility model:

[0033] In use, one hand separates the two clamping plates 3 to the sides, and the other hand places the optocoupler between the two clamping plates 3. Under the elastic pushing force of the two first springs 33, the two clamping plates 3 move closer together, clamping and fixing the optocoupler. The flexible anti-slip strips 31 on the side walls of the clamping plates 3 increase friction to prevent the optocoupler from sliding and avoid damage to the optocoupler. Then, the positioning frame 1 is placed on the PCB circuit board at the position where the optocoupler needs to be installed. The flexible support pad 11 on the bottom surface of the positioning frame 1 prevents the positioning frame 1 from damaging the structure of the PCB circuit board. After placement, the optocoupler is positioned directly above the installation location. By pressing the two fixing blocks 352, the two second springs 36 retract, and the two rectangular rods 35 move downward. The two rectangular rods 35 then move the two positioning plates 351 downward, further confirming that the optocoupler is accurately positioned above the installation location. Finally, the screw 13 is rotated, causing it to rotate and move downward inside the threaded hole 122, which in turn moves the moving plate 211 downward. The moving plate 211 then moves the C-frame 21 downward, which in turn moves the moving frame 2 downward. The moving frame 2 can then move the optocoupler, which is held by the clamping plate 3, to the installation location for installation.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
