Description

Technical Field

[0001] This disclosure relates to the field of optical coupler technology, and more particularly to an optical coupling structure and an optical coupler. Background Technology

[0002] An optocoupler is an electro-optical-electrical conversion device that uses light as a medium to transmit electrical signals. It consists of two parts: a light source and a light receiver. The light source and the light receiver are assembled in the same sealed housing and isolated from each other by a transparent insulator (16). The pins of the light source are the input terminals, and the pins of the light receiver are the output terminals. Common light sources are light-emitting diodes (LEDs), and light receivers are photodiodes, phototransistors, etc.

[0003] Optocoupler repair typically does not require disassembling its casing because it is a completely sealed solid-state device with an unrepairable internal structure; once damaged, the entire device must be replaced. An optocoupler consists of an infrared light-emitting diode (LED) and a photosensitive semiconductor (such as a phototransistor) encapsulated in an opaque, non-openable insulating casing. It achieves isolated transmission via an "electrical-optical-electrical" connection. Its packaging is a one-time manufacturing process, lacking a design that allows users or repair personnel to disassemble it; forced disassembly will damage the device.

[0004] Therefore, damaged optical couplers need to be completely disassembled and replaced. However, because optical couplers are small in size, disassembly and replacement can be inconvenient. Summary of the Invention

[0010] Optionally, two copper pillars are slidably inserted into the inside of the connecting box.

[0011] Optionally, an inclined block is fixed to the end of the insulating column protruding from the top of the copper column, vertical frames are fixed to both sides of the connecting box, and inclined plates are fixed to the top of the two vertical frames.

[0012] Optionally, the ejection assembly further includes: a second slide groove, a slider, a second bidirectional screw, and a connecting rod. The base plate is provided with a second slide groove at the bottom of the support plate, and a second bidirectional screw is rotatably installed inside the second slide groove.

The support plate is a right-angle plate, and the bottom and vertical surface of the support plate are in contact with the bottom and side of the encapsulation shell.

[0017] The technical solution provided in this disclosure may include the following beneficial effects:

[0018] 1. In this invention, a first drive motor drives a first bidirectional screw to rotate, and two sets of connecting boxes move along the first slide groove, so that the connecting boxes can move toward the middle coupler assembly, making it convenient for the connecting copper feet to be inserted into the interior of the connecting boxes. When the connecting box slides along the protrusion, the inclined block at the top of the copper pillar slides along the inclined surface and is squeezed, causing the copper pillar to move downward and contact the inserted connecting copper feet, connecting the copper feet and the copper pillar and the connecting wire to pass through, completing the installation and use of the coupler assembly. Furthermore, when replacing the coupler assembly, as the connecting box moves away from the encapsulation shell, the spring pushes the copper pillar upward, causing the bottom of the copper pillar to leave the connecting copper feet, disconnecting the electrical connection between the coupler assembly and the connecting box. The connecting wires on both sides are fixed by the wire guide ring, which can prevent the connecting wires in other positions from being pulled when the connecting box moves.

[0019] 2. The two trays of the present invention contact the bottom sides of the package shell, which can be installed in an adaptable manner. It needs to be manufactured in conjunction with the supporting equipment of the optoelectronic device manufacturing industry. Through the cooperation of the second drive motor and the transmission belt, the two second bidirectional screws rotate synchronously, so that the slider inside the second slide groove is threadedly engaged with the second bidirectional screw. After the connecting rod rotates, the trays move in the vertical direction, which can move the package shell up or down, thereby facilitating the removal and replacement of damaged coupler components, as well as the placement and installation of new coupler components on the base plate.

[0020] 3. In this invention, the connecting copper pin is inserted into the inside of the connecting box, while the insert frame on the connecting box is inserted into the slot of the rotating plate. The wrapping frame wraps around the outside of the first and second limiting plates and the top of the connecting copper pin, thus wrapping the entire connecting copper pin and preventing damage. When replacing the coupler assembly, the encapsulation shell is pushed upward by lifting the assembly. After the rotating plate moves to the upper end, the gear and toothed plate mesh to straighten the bent connecting copper pin, making it easy to remove the coupler assembly. The internal structure of the wrapping assembly is made of insulating plastic, which can prevent leakage. At the same time, the structure of the wrapping assembly can be manufactured in conjunction with the optoelectronic device manufacturing and sensitive element and sensor manufacturing industries, and can be produced in conjunction with the connecting assembly and coupler assembly to form an integrated coupler structure. When the coupler is damaged, the coupler assembly can be replaced separately without disassembling the entire structure, which facilitates subsequent replacement and installation and eliminates the need for rewiring.

[0039] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown in the present disclosure, an optical coupling structure and an optical coupler are proposed. The optical coupler includes a coupler assembly 1 and an optical coupling structure. The optical coupling structure includes a base plate 2, with connecting components 3 at both ends of the base plate 2. A connecting wire 6 is inserted into the outer end of the connecting component 3. The coupler assembly 1 is placed in the middle of the base plate 2. A wrapping component 4 is provided between the two ends of the coupler assembly 1 and the connecting component 3. Ejection components 5 are provided on both sides of the base plate 2 on the coupler assembly 1. A heat dissipation groove 21 is formed at the bottom of the base plate 2. The coupler assembly 1 includes a packaging shell 11, with the packaging shell 11 having two... A connecting copper foot 12 protrudes; the connecting assembly 3 includes a connecting box 31, of which two sets are provided, and the two sets of connecting boxes 31 are slidably installed on the top of both ends of the base plate 2. An insertion hole 32 is opened on the outer side of the connecting box 31 corresponding to the position of the connecting line 6, and the connecting line 6 is inserted into the insertion hole 32. A first sliding groove 34 is opened in the middle of the base plate 2, and the bottom of the connecting box 31 is slidably installed inside the first sliding groove 34; the ejection assembly 5 includes a support plate 53, of which two sets are provided, and the two sets of support plates 53 contact the bottom sides of the encapsulation shell 11; the wrapping assembly 4 includes a protruding plate 42. Rotating seats 54 are rotatably mounted at both ends of the through-plate 42. The rotating seats 54 are fixedly connected to the vertical surface of the support plate 53. The connecting copper feet 12 slide out from inside the through-plate 42. In this solution, the base plate 2, connecting assembly 3, wrapping assembly 4, and lifting assembly form a complete set with the coupler assembly 1. It can be manufactured by optoelectronic device manufacturing; sensitive element and sensor manufacturing; semiconductor device special equipment manufacturing such as integrated circuit production line equipment and IGBT production line equipment; electronic component and electromechanical component equipment manufacturing such as chip component production equipment and frequency device production equipment; magnetron sputtering equipment and excimer laser annealing equipment. This product is manufactured in conjunction with other electronic equipment manufacturing industries. During initial installation and use, the coupler assembly 1 is installed on the base plate 2 and connected to the connecting assembly 3. The two ends of the connecting assembly 3 are connected to the connecting wire 6 of the electronic device. The heat dissipation slots 21 of the base plate 2 dissipate heat from the coupler assembly 1. When the coupler assembly 1 is damaged, the connecting assembly 3 separates from the coupler assembly 1, and the lifting assembly pushes the coupler assembly 1 outward. The coupler assembly 1 is then replaced separately, installed on the base plate 2, and reconnected to the connecting assembly 3 to achieve circuit continuity. After the first installation, it is not necessary to disassemble the entire structure, making it convenient to replace and install the coupler.

[0041] like Figure 10As shown, in some embodiments, the coupler assembly 1 further includes: an insulating substrate 13, an LED module 14, and a receiving module 15. The top and bottom of the encapsulation shell 11 are fixed with the insulating substrate 13. The LED module 14 is fixed on the surface of the insulating substrate 13 at the top of the encapsulation shell 11, and the receiving module 15 is fixed on the surface of the insulating substrate 13 at the bottom of the encapsulation shell 11. The LED module 14 and the receiving module 15 are respectively fixedly connected to a copper pin 12 on one side. The LED module 14 and the receiving module 15 are perpendicularly corresponding, and a transparent insulator 16 is fixed between the LED module 14 and the receiving module 15.

[0042] It is understandable that the internal structure of the coupler assembly 1 is the same as the coupler principle of existing optoelectronic device manufacturing. The connecting copper pin 12 is sheet-shaped and can be bent. It is connected to the circuit through the connecting copper pin 12 at both ends. The LED module 14 and the receiving module 15 cooperate to realize the transmission of electrical signals.

[0043] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the connecting assembly 3 further includes: a first bidirectional screw 35, a first drive motor 39, and a protrusion 311. The first bidirectional screw 35 is rotatably mounted inside the first slide groove 34. The bottoms of the two connecting boxes 31 are threaded onto the two ends of the first bidirectional screw 35. The two ends of the base plate 2 are fixed with protrusions 311 on both sides of the first slide groove 34. The connecting boxes 31 slide along the protrusions 311. The first drive motor 39 is fixed at one end of the base plate 2 corresponding to the position of the first bidirectional screw 35. The output end of the first drive motor 39 is fixedly connected to the first bidirectional screw 35. A threading ring 33 is fixed at both ends of the base plate 2, and the connecting wire 6 passes through the threading ring 33. The inner... Two copper pillars 312 are slidably inserted into the connection box 31. The copper pillars 312 are electrically connected to the connecting wires 6 that are inserted into the insertion holes 32. The connecting copper feet 12 are inserted from the bottom of the connection box 31 and correspond to the copper pillars 312. An insulating post is fixed to the top of the copper pillar 312, and the insulating post at the top of the copper pillar 312 slides out of the top of the connection box 31. An inclined block 36 is fixed to the end of the insulating post at the top of the copper pillar 312. Vertical frames 38 are fixed to both sides of the connection box 31. An inclined plate 37 is fixed to the top of the two vertical frames 38. The inclined block 36 slides along the inclined surface of the inclined plate 37. A spring 310 is sleeved on the outer ring of the insulating post of the copper pillar 312, and the two ends of the spring 310 are fixedly connected to the inclined block 36 and the connection box 31, respectively.

[0044] Understandably, the first drive motor 39 drives the first bidirectional screw 35 to rotate, and the two sets of connecting boxes 31 move along the first slide groove 34, so that the connecting boxes 31 can move toward the middle coupler assembly 1, making it convenient for the connecting copper feet 12 to be inserted into the interior of the connecting boxes 31. When the connecting boxes 31 slide along the protrusion 311, the inclined block 36 at the top of the copper pillar 312 slides along the inclined surface and is squeezed, causing the copper pillar 312 to move downward and contact the inserted connecting copper feet 12. The connecting copper feet 12 and the copper pillar 312 are connected to the connecting wire 6, completing the installation and use of the coupler assembly 1. When replacing the coupler assembly 1, as the connecting boxes 31 move away from the encapsulation shell 11, the spring 310 pushes the copper pillar 312 upward, causing the bottom of the copper pillar 312 to leave the connecting copper feet 12, disconnecting the electrical connection between the coupler assembly 1 and the connecting boxes 31. The connecting wires 6 on both sides are fixed by the wire loop 33, which can prevent the connecting wires 6 in other positions from being pulled when the connecting boxes 31 move.

[0045] like Figure 3 and Figure 4 As shown, in some embodiments, the ejection assembly 5 further includes: a second groove 52, a slider 57, a second bidirectional screw 58, and a connecting rod 510. The base plate 2 has a second groove 52 at the bottom of the support plate 53, and the second bidirectional screw 58 is rotatably installed inside the second groove 52. The two ends of the second bidirectional screw 58 are threaded with sliders 57, and the sliders 57 slide along the inside of the second groove 52. The bottom of the support plate 53 is symmetrically connected to two connecting rods 510 through a pivot, and the other end of the connecting rod 510 is rotatably connected to the top of the slider 57 through a pivot. The support plate 53 is a right-angle plate, and the bottom and vertical surface of the support plate 53 are perpendicular to each other. The bottom and sides of the encapsulation shell 11 are in contact. The second drive motor 59 is fixed at the end of the base plate 2 near the first drive motor 39, corresponding to the position of the second bidirectional screw 58. The output end of the second drive motor 59 is fixedly connected to the second bidirectional screw 58. The other end of the base plate 2 is equipped with a transmission belt 51. The two pulleys of the transmission belt 51 are fixedly connected to the two second bidirectional screws 58. A gear 55 is rotatably mounted on the outer surface of the rotating seat 54. The gear 55 is fixedly connected to the rotating shaft of the rotating seat 54. A toothed plate 56 is fixed on the surface of the vertical frame 38 near the top. The toothed plate 56 is engaged with the support plate 53 after it moves upward.

[0046] It should be noted that the two trays 53 contact the bottom sides of the package shell 11 for adaptable installation. They need to be manufactured in conjunction with the optoelectronic device manufacturing industry. Through the cooperation of the second drive motor 59 and the transmission belt 51, the two second bidirectional screws 58 rotate synchronously, so that the slider 57 inside the second slide groove 52 is threadedly engaged with the second bidirectional screw 58. After the connecting rod 510 rotates, it moves the trays 53 vertically, which can move the package shell 11 up or down, thereby facilitating the removal and replacement of the damaged coupler assembly 1, and the placement and installation of the new coupler assembly 1 on the base plate 2.

[0047] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the packaging assembly 4 further includes: a first limiting plate 43, a second limiting plate 45, an insert frame 44, and a slot 46. The bottom plate 2 is fixed with the first limiting plate 43 on both sides of the placement position of the packaging shell 11, and the bottom plate 2 is fixed with the second limiting plate 45 on the outside of the first limiting plate 43. The first limiting plate 43 and the second limiting plate 45 respectively contact the two bent bottoms of the connecting copper feet 12. The connecting box 31 is fixed with the insert frame 44 on the side facing the through plate 42. The through plate 42 is provided with a slot 46 on the side corresponding to the insert frame 44, and the insert frame 44 is inserted into the slot 46. The connecting box 31 is fixed with a packaging frame 41 on the top of the insert frame 44. The packaging frame 41 wraps around the top of the insert frame 44, the through plate 42, the first limiting plate 43, and the second limiting plate 45.

[0048] It should be noted that the connecting copper feet 12 protruding from both ends of the encapsulation shell 11 are initially in a vertically downward state. After passing through the exit plate 42, the encapsulation shell 11 and the connecting copper feet 12 descend together via the lifting assembly. During the descent, the gear 55 meshes with the toothed plate 56, causing the exit plate 42 to rotate and bend the vertically positioned connecting copper feet 12 laterally. Finally, the bent portion of the connecting copper feet 12 protruding from the encapsulation shell 11 contacts the top of the first limiting plate 43, and the laterally bent portion contacts the top of the second limiting plate 45. At this point, the connecting copper feet 12 correspond to the insertion holes 32 of the connecting box 31. As the connecting box 31 moves closer to the encapsulation shell 11, the connecting copper feet 12 are inserted into the interior of the connecting box 31. Simultaneously, the insertion frame 44 on the connecting box 31 is inserted into the slot 46 of the rotating plate, and the encapsulation frame 41 encloses the first limiting plate 45. The outer side of the position plate 43 and the second limiting plate 45, as well as the top of the connecting copper foot 12, are wrapped to prevent damage to the connecting copper foot 12. When replacing the coupler assembly 1, the encapsulation shell 11 is pushed upward by lifting the assembly. After the rotating plate moves to the upper end, the gear 55 and the toothed plate 56 mesh to straighten the bent connecting copper foot 12, thus facilitating the removal of the coupler assembly 1. The internal structure of the encapsulation assembly 4 is made of insulating plastic to prevent leakage. At the same time, the structure of the encapsulation assembly 4 can be manufactured in conjunction with the optoelectronic device manufacturing and sensitive element and sensor manufacturing industries. It can be produced in conjunction with the connecting assembly 3 and the coupler assembly 1 to form an integrated coupler structure. When the coupler is damaged, the coupler assembly 1 can be replaced separately without disassembling the entire structure, which is convenient for subsequent replacement and installation and does not require rewiring.

[0049] Working principle:

[0050] In use, the internal structure of the coupler assembly 1 is the same as that of couplers manufactured in existing optoelectronic devices. The connecting copper pins 12 are sheet-like and can be bent. They are connected to the circuit through the two ends of the connecting copper pins 12. The LED module 14 and the receiving module 15 cooperate to transmit electrical signals. During initial installation, the coupler assembly 1 is mounted on the base plate 2 and connected to the connecting assembly 3. The two ends of the connecting assembly 3 are connected to the connecting wires 6 of the electronic device. The first drive motor 39 drives the first bidirectional screw 35 to rotate, and the two sets of connecting boxes 31 move along the first slide groove 34, so that the connecting boxes 31 can move towards the middle coupler assembly 1, which facilitates the insertion of the connecting copper pins 12 into the interior of the connecting box 31. When the connecting box 31 slides along the protrusion 311, the inclined top of the copper column 312... After block 36 slides along the inclined plane, it is squeezed, causing copper pillar 312 to move downwards and contact the inserted connecting copper foot 12. The connecting copper foot 12 and copper pillar 312 are connected to the connecting wire 6, completing the installation and use of coupler assembly 1. When replacing coupler assembly 1, as the connecting box 31 moves away from the encapsulation shell 11, spring 310 pushes copper pillar 312 upwards, disengaging the bottom of copper pillar 312 from the connecting copper foot 12, disconnecting the electrical connection between coupler assembly 1 and connecting box 31. The connecting wires 6 on both sides are fixed by the wire loop 33, which can prevent the connecting wires 6 in other positions from being pulled when the connecting box 31 moves. The heat dissipation groove 21 of the base plate 2 dissipates heat from the coupler assembly 1. The two support plates 53 contact the bottom sides of the encapsulation shell 11 for adaptable installation. This product is manufactured to support the optoelectronic device manufacturing industry. Through the cooperation of the second drive motor 59 and the transmission belt 51, the two second bidirectional screws 58 rotate synchronously, causing the slider 57 inside the second slide groove 52 to engage with the second bidirectional screw 58. This allows the connecting rod 510 to rotate, moving the support plate 53 vertically. This allows the package shell 11 to move upwards or downwards, facilitating the removal and replacement of damaged coupler components 1, and the placement and installation of new coupler components 1 on the base plate 2. The connecting copper feet 12 protruding from both ends of the package shell 11 are initially vertically downwards. After passing through the through plate 42, the components are lowered by lifting, causing the package shell 11 and connecting copper feet 12 to descend together. During this descent, the gear 55 and the toothed plate 56... The engagement causes the through plate 42 to rotate, bending the vertical connecting copper foot 12 laterally. Finally, the bent portion of the connecting copper foot 12, passing through the encapsulation shell 11, contacts the top of the first limiting plate 43, and the laterally bent portion contacts the top of the second limiting plate 45. At this point, the connecting copper foot 12 corresponds to the insertion hole 32 of the connecting box 31. As the connecting box 31 moves closer to the encapsulation shell 11, the connecting copper foot 12 is inserted into the interior of the connecting box 31. Simultaneously, the insertion frame 44 on the connecting box 31 is inserted into the slot 46 of the rotating plate. The wrapping frame 41 wraps around the outside of the first and second limiting plates 43 and the top of the connecting copper foot 12, thus protecting the entire connecting copper foot 12 from damage. This is important when replacing the coupler assembly 1.The lifting assembly pushes the encapsulation shell 11 upwards. After the rotating plate moves to the upper end, the gear 55 meshes with the toothed plate 56, straightening the bent connecting copper foot 12, thus facilitating the removal of the coupler assembly 1. The internal structure of the encapsulation assembly 4 is made of insulating plastic, which can prevent leakage.
