Description

Technical Field

[0001] This invention relates to the field of optocouplers, and more particularly to optocoupler devices. Background Technology

[0002] An optocoupler drives a light-emitting diode to emit light through an electrical signal on the input side, and the photosensitive tube on the output side receives the light and converts it into an electrical signal. There is no direct electrical connection between the input and output; the signal is transmitted only through light. This prevents high voltage from entering the low voltage side and causing the sensitive element to break down. In addition, the isolation characteristics of the optocoupler can block the transmission of interference signals and prevent the control signal from being distorted. However, traditional optocouplers are planar, with light-emitting diodes and phototransistors arranged horizontally on the substrate. The light is diffused horizontally, causing most of the light to be absorbed by the substrate surface or scattered into irrelevant areas. The transmission efficiency is inherently weak, and the transmission distance cannot be precisely controlled, depending entirely on the spacing of the components on the substrate. This makes it impossible to adjust the isolation withstand voltage of the device, thus limiting the application scenarios of the device.

[0003] Therefore, the present invention provides an optocoupler. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing an optocoupler to address the problem of poor optical transmission performance in the aforementioned technical solutions. To achieve the above objectives, the present invention adopts the following technical solution: a modular partition wall pipeline integrated layout structure, including a pipe shell, with a light-receiving mechanism and a light-emitting mechanism disposed on the upper part of the pipe shell. The light-receiving mechanism includes a pipe seat, an anode, a cathode, a collector, an emitter, an internal electrode, and a phototransistor chip.

[0015] In a preferred embodiment, an arc-shaped clamp is fixedly connected to the side end of the tube shell, the surface of the arc-shaped clamp is slidably connected to the clamp plate through a groove, and the surface of the cover plate is provided with ventilation holes.

[0016] The technical effect of adopting the above-mentioned further solution is that the cover plate can be fixed to the surface of the tube shell by means of the setting.

[0017] This invention provides an optocoupler. It has the following advantages: By vertically arranging phototransistor chips and diode chips, the light utilization rate and anti-interference capability are improved.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention provides a technical solution: an optocoupler, including a housing 1, with a light-receiving mechanism and a light-emitting mechanism disposed on the upper part of the housing 1. The light-receiving mechanism includes a housing 2, an anode 3, a cathode 4, a collector 5, an emitter 6, an internal electrode 7, and a phototransistor chip 8. The light-emitting mechanism includes a substrate 9 and a light-emitting diode chip 10. The surface of the housing 2 is fixedly connected to the housing 1, so that the housing 2 can be positioned in the same location as the housing 1. The leads of the phototransistor chip 8 are fixedly connected to the housing 2 by conductive adhesive. The substrate 9 is disposed on the upper end of the housing 2, and the leads of the light-emitting diode chip 10 are... The feet are fixedly connected to the substrate 9 with conductive adhesive, so that the light-emitting diode chip 10 can be connected to the circuit through the substrate 9. The space between the phototransistor chip 8 and the light-emitting diode chip 10 is filled with light-guiding adhesive 11. By vertically setting the phototransistor chip 8 and the light-emitting diode chip 10, the vertical light path is replaced with the diffuse light path, which improves the light utilization rate and anti-interference ability. At the same time, the controllable vertical spacing and the use of light-guiding adhesive 11 to fill the gap break through the pressure resistance limit of the planar structure. While improving the light transmission capability, it also improves the isolation pressure resistance of the device and increases the application range of the device.

[0023] like Figures 1-3As shown: the side end of the anode 3 is fixedly connected to the tube seat 2, and the side end of the cathode 4 is fixedly connected to the tube seat 2. The anode 3 and the cathode 4 introduce the circuit into the tube seat 2, so that the light-emitting mechanism can be connected to the circuit.

[0024] like Figures 1-4 As shown: the side end of the collector 5 is fixedly connected to the tube socket 2, and the side end of the emitter 6 is fixedly connected to the tube socket 2. The collector 5 and the emitter 6 introduce the circuit into the tube socket 2, so that the light receiving mechanism can be connected to the circuit.

[0025] like Figures 1-5 As shown: the bottom surface of substrate 9 is gold-plated, and the top surface of substrate 9 is made of black material. The gold plating on the bottom surface improves the conductivity of substrate 9, while the black material on the top surface of substrate 9 provides a certain light-shielding effect, which to some extent prevents light from passing through substrate 9 and interfering with the judgment of phototransistor chip 8.

[0026] like Figures 3-4 As shown: The lower end of the inner electrode 7 is fixedly connected to the tube seat 2. There are two inner electrodes 7. The lower end of the substrate 9 is fixedly connected to the inner electrode 7 through conductive adhesive. The substrate 9 is fixed on the tube seat 2, and the light-emitting diode chip 10 is connected to the anode 3 and the cathode 4 through the inner electrode 7.

[0027] like Figures 2-3 As shown: A rotating shaft 12 is rotatably connected to the side end of the tube shell 1. The tube shell 1 and the rotating shaft 12 are adapted to each other. A cover plate 13 is fixedly connected to the surface of the rotating shaft 12. A clamping plate 14 is fixedly connected to the side end of the cover plate 13. A pull handle 15 is fixedly connected to the end of the clamping plate 14. The clamping plate 14 can be pulled outward through the pull handle 15. A slot 16 is opened on the surface of the clamping plate 14. By setting the cover plate 13 at the upper end of the tube shell 1 to block it, the light-blocking effect of the device is improved, the interference of external stray light is avoided, and the accuracy of the phototransistor chip 8 is reduced.

[0028] like Figures 2-3 As shown: A curved clamp head 17 is fixedly connected to the side end of the tube shell 1. The surface of the curved clamp head 17 is slidably connected to the clamp plate 14 through the clamp groove 16. The surface of the cover plate 13 is provided with a vent hole 18. The vent hole 18 is located on the side of the mounting position of the substrate 9. Through the shielding of the substrate 9, the device can play a certain heat dissipation role while preventing external stray light from entering the interior. When the cover plate 13 is rotated until the clamp plate 14 presses the curved clamp head 17, the clamp plate 14 will be affected by the arc surface of the curved clamp head 17 and rotate a certain angle towards the outside. When the clamp groove 16 is aligned with the curved clamp head 17, it returns to its original shape. Thus, by inserting the curved clamp head 17 into the clamp groove 16, the cover plate 13 is fixed. To unlock the cover plate 13, simply pull the handle 15 outward and flip it.

[0029] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this optocoupler device mounts a phototransistor chip 8 on a socket 2 and a light-emitting diode chip 10 on a substrate 9. The socket 2 and the substrate 9 are stacked and fixed. By vertically setting the phototransistor chip 8 and the light-emitting diode chip 10, a vertical light path is used to replace the diffuse light path, which improves the light utilization rate and anti-interference ability. At the same time, the controllable vertical spacing and the use of light guide adhesive 11 for potting and filling not only improve the light transmission capability, but also break through the voltage resistance limit of the planar structure, improve the isolation voltage resistance of the device, and increase the application range of the device. When the cover plate 13 is rotated to the point where the clamping plate 14 presses the arc-shaped clamping head 17, the clamping plate 14 will rotate a certain angle due to the influence of the arc surface of the arc-shaped clamping head 17. When the clamping slot 16 is aligned with the arc-shaped clamping head 17, it will return to its original shape, thereby fixing the cover plate 13 by inserting the arc-shaped clamping head 17 into the clamping slot 16. To unlock the cover plate 13, simply pull the handle 15 outward and flip it. Through the shielding of the substrate 9, the device can play a certain heat dissipation role while preventing external stray light from entering the interior, thereby improving the judgment accuracy and reliability of the phototransistor chip 8.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
