[0001] The invention belongs to the technical field of couplers, and in particular relates to an optoelectronic component coupler that is easy to adjust. Background Art

[0002] A photocoupler is a semiconductor optoelectronic device that converts optical signals into electrical signals or electrical signals into optical signals. It is usually composed of a light-emitting element (such as a light-emitting diode) and a photosensitive element (such as a phototransistor) encapsulated in the same housing, and transmits electrical signals through the conversion of electricity → light → electricity. The photocoupler can achieve electrical isolation between the input and output ends, thereby protecting the circuit from external interference and damage, and the transmission speed of the photocoupler is usually fast, which can meet the needs of high-speed signal transmission.

[0003] In the prior art, the traditional coupler plastic shell is a miniature packaging structure with poor heat dissipation effect. It will increase internal stress under high temperature, thus causing damage due to temperature changes or mechanical vibrations. On the other hand, the optocoupler can adjust the output electrical signal by adjusting parameters such as the intensity, frequency and pulse width of the input optical signal, but the actual operation is more troublesome. Due to its small size, it is impossible to add relevant structures inside to assist in adjusting the intensity of the optical signal received by the optical receiver, thereby reducing its practicality.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-7 The optoelectronic component coupler shown in the figure is easy to adjust, including an adjustable coupler 1, the adjustable coupler 1 includes a long insulating shell 2, a bent pin 3, a metal base 4, a light receiving component 5, an optical signal adjustment component 6 and a heat dissipation component 7, the surface of the bent pin 3 is fixedly connected to the surface of the long insulating shell 2, the metal base 4 is welded to the top of the bent pin 3, the light receiving component 5 is welded to one side of the metal base 4, the optical signal adjustment component 6 is rotatably connected to the inside of the long insulating shell 2, the heat dissipation component 7 is installed in the middle of the top of the long insulating shell 2, and a heat absorption component 8 is also installed on the opposite side of the metal base 4;

[0032] The bent pins 3 are inserted into the corresponding holes on the circuit board and welded to fix them. The metal base 4 is used to connect the light receiving component 5 and increase the heat dissipation area. The light emitted by the light receiving component 5 is received and converted into an electrical signal. The optical signal adjustment component 6 can help filter or adjust the received optical signal and is used to directly adjust the sensitivity of the light receiving component 5. The heat dissipation component 7 improves the heat dissipation efficiency of the long-length insulating shell 2 by freely opening and closing. The heat absorption component 8 can directly contact the metal base 4 when the high-length insulating shell 2 is at a high temperature and is used to accelerate heat conduction to reduce the internal temperature of the metal base 4 and the light receiving component 5.

[0033] This product uses multiple groups of single-pass filters 20 with different filter transmission bands to directly act between the phosphorescent organic light emitting device 9 and the photosensitive transistor 10, thereby adjusting the light signal intensity of the light emitted by the phosphorescent organic light emitting device 9, eliminating the process of adjusting the coupler parameters separately, and the bent pins 3 are inserted into the corresponding holes on the circuit board and welded and fixed. The metal base 4 is used to connect the light receiving component 5 and increase the heat dissipation area. After the light is emitted by the light receiving component 5, it is received and converted into an electrical signal. The optical signal adjustment component 6 can help filter or adjust the received optical signal and is used to directly adjust the sensitivity of the light receiving component 5. The heat dissipation component 7 improves the heat dissipation efficiency of the high-length insulating shell 2 by freely opening and closing. The heat absorption component 8 can directly contact the metal base 4 when the high-length insulating shell 2 is at a high temperature and is used to accelerate heat conduction to reduce the internal temperature of the metal base 4 and the light receiving component 5.

[0034] The light receiving component 5 includes a phosphorescent organic light emitting device 9, a phototransistor 10 and a variable resistor 11. The phosphorescent organic light emitting device 9 is mounted on the upper end of the phototransistor 10, and the variable resistor 11 is welded to the output end of the phototransistor 10 through a lead wire.

[0035] Phosphorescent organic light-emitting diodes have high efficiency, high brightness and adjustable colors for the light-emitting part. The phototransistor 10 converts the optical signal into an electrical signal, and the variable resistor 11 can adjust the electrical signal by changing the resistance. In specific operation, the sliding shaft 13 can be rotated by the control end, and the sliding shaft 13 drives the moving contact piece 14 to rotate along the surface of the carbon film 16 to maintain good electrical contact with the carbon film 16. When the moving contact piece 14 moves on the carbon film 16, it will change the resistance value in the circuit, thereby realizing the control or adjustment of the circuit, thereby directly adjusting the intensity of the optical signal.

[0036] The variable resistor 11 includes a resistor housing 12, a sliding shaft 13, a moving contact piece 14, a fixed piece 15 and a carbon film 16. The carbon film 16 is installed inside the resistor housing 12 to contact the fixed piece 15. The fixed piece 15 is installed on the outside of the resistor housing 12. The outside of the sliding shaft 13 is fixedly connected to the moving contact piece 14. The moving contact piece 14 is slidably connected to the outside of the carbon film 16 to change the contact area to change the resistance value.

[0037] The optical signal adjustment component 6 includes a support base 17, a rotating bracket 18, a small motor 19 and a single-pass filter 20. The support base 17 is installed inside the high-length insulating shell 2. The rotating bracket 18 is rotatably connected to the middle part of the support base 17. The motor shaft of the small motor 19 is fixedly connected to one end of the rotating bracket 18 through a coupling. The single-pass filter 20 is installed on the outside of the rotating bracket 18.

[0038] The annular array of single-pass filters 20 is outside the rotating bracket 18, and the filter transmission bandwidths of the single-pass filters 20 are not equal.

[0039] During operation, a small motor 19 at the bottom can be started, and the small motor drives the rotating bracket 18 at the upper end to rotate. According to the light intensity, a suitable single-pass filter 20 can be selected to control the amount of light passing through and block it in the gap between the phosphorescent organic light emitting device 9 and the phototransistor 10, thereby achieving a direct shading effect and reducing the electrical signal strength.

[0040] The heat absorption assembly 8 includes a small motor 21, a fine-polishing plate 22, a fixed block 23, a positioning rod 24, a tension spring 25, a silicone rubber plate 26 and a wear-resistant block 27. The small motor 21 is installed on the outside of the fixed block 23, the fixed block 23 is fixedly connected to the inside of the high-length insulating shell 2, the positioning rod 24 is installed on one side of the silicone rubber plate 26, the tension spring 25 is fixedly connected to the opposite sides of the positioning rod 24 and the fixed block 23, the wear-resistant block 27 is adhesively connected to the inside of the silicone rubber plate 26 for continuous contact with the fine-polishing plate 22, and the fine-polishing plate 22 is installed on the outside of the output end of the small motor 21.

[0041] A telescopic rod 28 is also installed inside the tension spring 25 .

[0042] When the metal base 4 and the light receiving component 5 are hot, the small motor can be automatically started to drive the fine polishing plate 22 to rotate. Since the tension spring 25 located in the middle of the positioning rod 24 and the fixing block 23 is always in a stretched state, the wear-resistant block 27 cooperates with the silicone rubber plate 26 to abut against the surface of the fine polishing plate 22 under the elastic support, and cooperates with the rotation of the fine polishing plate 22, so that the silicone rubber plate 26 can contact the metal base 4 and the light receiving component 5 in the expanded position. The silicone rubber plate 26 fully conducts heat to the metal base 4 and heats up slowly, thereby reducing the overall temperature of the metal base 4 and the light receiving component 5, and preventing damage to the phosphorescent organic light emitting device 9 and the phototransistor 10 caused by temperature changes.

[0043] The heat dissipation assembly 7 includes a limiting slot 29, an exhaust diaphragm 30 and a thermoplastic elastomer 31. The limiting slot 29 is installed in the middle of the top end of the high-length insulating shell 2, the exhaust diaphragm 30 is installed inside the limiting slot 29, and the thermoplastic elastomer 31 is adhesively connected to the top of the high-length insulating shell 2 to push open the exhaust diaphragm 30.

[0044] An air outlet 32 ​​is formed through the limiting groove 29 .

[0045] The thermoplastic elastomer 31 is TPE room temperature elastic glue. The thermoplastic elastomer 31 continuously receives the internal temperature of the high-length insulating shell 2. When the high-length insulating shell 2 heats up, the thermoplastic elastomer 31 expands and pushes open the exhaust diaphragm 30 to expose the air hole 32, so that the device can enhance heat dissipation until the internal temperature drops and the thermoplastic elastomer 31 recovers, which is convenient for recycling.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
