[0001] The application belongs to the technical field of couplers, and particularly relates to an optoelectronic component coupling instrument convenient to adjust. BACKGROUND

[0002] An optoelectronic coupler is a kind of semiconductor optoelectronic device for converting optical signals into electrical signals or converting electrical signals into optical signals. It usually encapsulates a light-emitting element (such as a light-emitting diode) and a photosensitive element (such as a photosensitive triode) in the same shell, and transmits electrical signals through the conversion of electricity-optics-electricity. The optoelectronic coupler can realize electrical isolation between the input end and the output end, thereby protecting the circuit from external interference and damage. The transmission speed of the optoelectronic coupler is usually fast, which can meet the demand of high-speed signal transmission.

[0003] In the prior art, the traditional coupler glue shell is a micro encapsulation structure, and the heat dissipation effect is poor. At high temperature, the internal stress is increased, thereby causing damage caused by temperature change or mechanical vibration.
