Description

Technical Field

[0001] The utility model relates to the technical field of couplers, in particular to a driving optoelectronic coupler. Background Art

[0002] An optoelectronic coupler is an electro-optical-electrical conversion device that transmits electrical signals through light. 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. 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, and light receivers are photosensitive diodes, photosensitive transistors, etc.

[0003] The Chinese patent discloses a single-channel high-speed optoelectronic coupler (authorization publication number CN207966979U). This patented technology can improve the transmission rate, enabling the optoelectronic coupler to be used as an aerospace device in the aerospace field. However, the pins of this optoelectronic coupler are prone to damage during transportation. When the pins of the optoelectronic coupler are damaged, it is usually replaced with a new optoelectronic coupler, and the damaged optoelectronic coupler is placed in the waste area, resulting in waste. At the same time, the heat dissipation frame on the existing optoelectronic coupler is not easy to disassemble, making it inconvenient to clean later.

[0004] Therefore, those skilled in the art provide a driving optoelectronic coupler to solve the problems raised in the above background art. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a driving optoelectronic coupler, which includes an optoelectronic coupler body. A limiting block is arranged inside the optoelectronic coupler body. A clamping groove is opened inside the limiting block, and the insertion of the light-sensitive diode connector is facilitated inside the clamping groove. A connecting block is arranged on the top of the limiting block. A fastening bolt is arranged on the connecting block, and a cross groove is arranged on the fastening bolt.

[0006] Preferably: A lower cover body is arranged at the bottom of the optoelectronic coupler body, and an upper cover body is arranged on the upper part of the lower cover body. A supporting bottom ring is fixedly arranged at the bottom of the lower cover body, and a circuit board is arranged inside the lower cover body. An insertion ring is arranged at the upper end of the lower cover body, and a slot is opened inside the upper cover body. The slot and the insertion ring are inserted and connected with each other. Four bottom columns are arranged at the four corners of the lower end of the upper cover body.

[0007] Preferably, a heat dissipation frame is provided on the upper cover body. The number of heat dissipation frames is two, and they are detachably arranged. A dust-proof filter screen is provided on the heat dissipation frame. A placement opening is provided on the upper cover body, and a nameplate is placed inside the placement opening. A light-sensitive diode connector is inserted and connected to the side of the opto-coupler body. The number of the provided limit blocks, card slots, light-sensitive diode connectors, connection blocks, and fastening bolts is three, and they are distributed on the opto-coupler body. When the internal heat is too high, heat dissipation is timely, greatly improving the service life of the opto-coupler body. At the same time, the dust-proof filter screen plays a dust-proof effect, avoiding the influence caused by dust entering, and the practicability is stronger. When it is necessary to disassemble the heat dissipation frame on the opto-coupler body, just pull out the bottom column from the lower cover body and pull out the insertion ring from the inside of the slot, then the upper cover body and the lower cover body can be disassembled, and the dust-proof filter screen and the heat dissipation frame can be disassembled from the opto-coupler body, and the practicability is good.

[0008] The technical effects and advantages of the present utility model:

[0009] 1. When the light-emitting diode connectors on the opto-coupler body are damaged during transportation, the fastening bolts are rotated by using the cross grooves on the fastening bolts, so that the limit blocks are separated from the inside of the card slots, which is convenient to take out the three damaged light-sensitive diode connectors. At the same time, new light-sensitive diode connectors can be replaced and installed, avoiding excessive waste of resources and reducing losses. It solves the defect that the pins of the opto-coupler body in the prior art are easily damaged during transportation. When the pins of the opto-coupler body are damaged, usually a new opto-coupler is replaced, and the damaged opto-coupler body is placed in the waste, resulting in the problem of waste.

[0010] 2. When the internal heat is too high, heat dissipation is timely, greatly improving the service life of the opto-coupler body. At the same time, the dust-proof filter screen plays a dust-proof effect, avoiding the influence caused by dust entering, and the practicability is stronger. When it is necessary to disassemble the heat dissipation frame on the opto-coupler body, just pull out the bottom column from the lower cover body and pull out the insertion ring from the inside of the slot, then the upper cover body and the lower cover body can be disassembled, and the dust-proof filter screen and the heat dissipation frame can be disassembled from the opto-coupler body, which is convenient to clean the heat dissipation frame after using for a period of time, and the practicability is good. It solves the problem that the heat dissipation frame on the existing opto-coupler is not easy to disassemble and is inconvenient to clean later. Description of the Drawings
