Adjustable light coupling structure with fast response characteristics

Abstract

This utility model discloses an adjustable optocoupler structure with fast response characteristics, relating to the field of optocoupler structure technology, including a base plate, a fixing structure, and a heat dissipation structure. The lower protective box is firmly fixed to the top of the base plate and closely cooperates with the upper protective cover to form a sealed protective space, providing protection for the internal adjustable optocoupler structure. When the buckle is engaged and a slight force is applied, pressing causes the protruding button to retract, disengaging from the fixing groove. Simultaneously, the first and second locking blocks slide out of the first and second locking slots, respectively. The entire process is smooth and natural, allowing the upper protective cover to be quickly lifted, fully exposing the adjustable optocoupler structure inside the lower protective box. This facilitates detailed inspection, efficient maintenance, and precise debugging by operators. Opening the cabinet door separately allows operators to perform targeted inspections and maintenance of the optocoupler structure, significantly improving work efficiency and reducing unnecessary disassembly operations.

Description

Technical Field

[0001] This utility model relates to the field of optocoupler structure technology, specifically an adjustable optocoupler structure with fast response characteristics. Background Technology

[0002] In fields such as automation control, signal transmission, and industrial inspection, optocouplers, with their electrical isolation and strong anti-interference characteristics, have become core components for ensuring stable signal transmission. However, traditional optocoupler structures have significant shortcomings. On the one hand, their heat dissipation design is insufficient, making it difficult to quickly dissipate the heat generated by internal components. Long-term operation can easily lead to performance degradation or even component damage due to high temperatures, which not only shortens the equipment's lifespan but also affects the stability and accuracy of signal transmission. On the other hand, their protective performance is weak, lacking effective dustproof and waterproof measures and electromagnetic shielding design. In complex industrial environments with dense dust, high humidity, rain, or strong electromagnetic interference, external pollutants can easily penetrate the interior, interfering with the normal operation of the optocoupler and making it unable to withstand the corrosive effects of complex industrial environments. In addition, the wiring fixing method is rudimentary, relying solely on simple bundling. Under equipment vibration, this can easily cause the wiring to loosen and make poor contact, resulting in unstable signal transmission, data loss, and other problems, seriously affecting the overall reliability of the system. Furthermore, maintenance and repair are inconvenient, and the disassembly process is cumbersome, further restricting their application in modern industrial scenarios. Therefore, those skilled in the art have provided an adjustable optocoupler structure with fast response characteristics to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable optocoupler structure with fast response characteristics to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adjustable optocoupler structure with fast response characteristics includes a base plate, a fixing structure, and a heat dissipation structure. A lower protective box is fixedly connected to the top of the base plate, and an upper protective cover is movably connected to the lower protective box. A heat dissipation structure is detachably connected to one side of the upper protective cover. Three circular holes are opened on the corresponding sides of the upper protective cover and the lower protective box, and a sealing ring is fixedly connected to each circular hole. A fixing structure is fixedly connected to the outer end of each circular hole on both sides of the upper protective cover.

[0006] As a further embodiment of this utility model: the fixing structure includes a lower fixing block, a rubber plate, a bolt, a nut, a connecting block, an upper fixing block, and a round shaft. The lower fixing block is connected to the upper fixing block at one edge via the round shaft, and the upper fixing block is rotatably connected to the round shaft. The lower fixing block is fixedly connected to the round shaft. A clamping groove is formed between the lower fixing block and the upper fixing block, and a rubber plate is fixedly connected to the inner side of each of them.

[0007] As a further embodiment of this utility model: both the lower fixing block and the upper fixing block are fixedly connected to a connecting block on the side away from the circular shaft, the two connecting blocks are connected by bolts, and two nuts are threadedly connected to the outer ends of the two connecting blocks and the bolts.

[0008] As a further embodiment of this utility model: the heat dissipation structure includes a heat-conducting plate, a mounting plate, a heat dissipation plate, and screws. The heat dissipation plate is fixedly connected to one side of the heat-conducting plate, and the heat-conducting plate passes through the upper protective cover and extends into the lower protective box. Mounting plates are fixedly connected to both edges of one side of the heat dissipation plate. Each mounting plate is connected to the upper protective cover by two screws, and the screws are threadedly connected to the upper protective cover and the mounting plate.

[0009] As a further improvement of this utility model: a cabinet door is hinged to one edge of the upper protective cover, and fastening grooves are provided on the upper part of both sides of the upper protective cover.

[0010] As a further improvement of this utility model: the bottom of the upper protective cover is fixedly connected to the two opposite sides of the second and the first locking block respectively, and the first locking block is movably connected to a protruding button on one side by a spring.

[0011] As a further embodiment of this utility model: the inner wall of the lower protective box is plated with copper to form an electromagnetic shielding layer, and an adjustable optocoupler structure body is placed inside the lower protective box. The adjustable optocoupler structure body includes a digital potentiometer connected to an external controller via an SPI interface. The heat-conducting plate on the heat dissipation structure is in close contact with the heating element of the adjustable optocoupler structure body through thermal grease.

[0012] As a further embodiment of this utility model: the top of the base plate has a second slot and a first slot respectively provided on opposite sides, corresponding to the second and first slots, and is embeddedly connected to them. A fixing groove is provided on one side of the first slot, corresponding to the raised button, and the fixing groove is snapped together with the raised button.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During use, the lower protective box is firmly fixed to the top of the base plate and fits tightly with the upper protective cover to form a sealed protective space, providing comprehensive protection for the internal adjustable optocoupler structure. When a full overhaul of the optocoupler structure is required, simply insert your finger into the latch and apply slight force. At this time, the latching connection between the raised button and the fixed groove will come into play. Pressing the button will cause it to retract and disengage from the fixed groove. Simultaneously, the first and second latches will slide out of the first and second latches. The entire process is smooth and natural, allowing the upper protective cover to be lifted quickly, fully exposing the adjustable optocoupler structure inside the lower protective box. This facilitates detailed inspection, efficient maintenance, and precise debugging by operators. When only a quick local inspection or simple maintenance is required, simply open the cabinet door. Once the door is open, some internal components and wiring are clearly visible, allowing operators to easily perform targeted inspections and maintenance of the optocoupler structure, greatly improving work efficiency and reducing unnecessary disassembly operations, effectively extending the equipment's service life.

[0015] 2. The round holes on the corresponding sides of the upper protective cover and the lower protective box are used for the signal transmission lines of the optocoupler structure to pass through. The sealing ring inside the round hole can effectively prevent dust, moisture and other substances from entering the protective box, protecting the lines and internal components. The fixing structure is used to fix the lines passing through the round holes. The lower fixing block and the upper fixing block are connected by a rotating round shaft, forming a clamping groove between them. The rubber plate on the inside increases the friction and prevents damage to the lines. The lower fixing block and the upper fixing block are fastened by connecting blocks, bolts and nuts. The clamping force can be adjusted according to the thickness of the lines to ensure line stability and avoid signal transmission caused by line shaking, thus ensuring the stability and reliability of the signal transmission of the optocoupler structure.

[0016] 3. The adjustable optocoupler structure generates heat during operation. The internal digital potentiometer is connected to an external controller via an SPI interface to adjust the optocoupler performance. The heat dissipation structure plays a crucial role here. The heat-conducting plate is in close contact with the heat-generating element of the adjustable optocoupler structure through thermal grease, which can quickly conduct heat away. The heat-conducting plate extends through the upper protective cover and connects to the heat sink. The heat sink is fixed to the upper protective cover by a mounting plate and screws. Its large surface area is conducive to heat dissipation to the external environment, reducing the internal temperature, ensuring that the optocoupler structure operates at a suitable temperature, and improving fast response characteristics and stability.

[0017] 4. The inner wall of the lower protective box is plated with copper to form an electromagnetic shielding layer, which can effectively shield external electromagnetic interference, prevent electromagnetic signals from affecting the internal components and signal transmission of the optocoupler structure, ensure the accuracy and stability of the output signal of the optocoupler structure, and enable it to work reliably in complex electromagnetic environments.
