Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to a component positioning device for a QSFP optical module. Background Art

[0002] The function of the optical module is to realize photoelectric conversion. One end converts the electrical signal into an optical signal, which is transmitted to the other end through the optical fiber and then converted into an electrical signal. Its advantage is that it can transmit over long distances without affecting the quality of the signal. Secondly, the QSFP+ optical module is one of the packaging of the optical module. Its function is also photoelectric conversion. The transmission rate is 40Gbps. It is used in optical switches, servers and other devices with QSFP+ interfaces to realize communication. However, there are some problems when using this device. After the staff installs and inserts the optical module into the sfp interface, the vibration generated by the internal components of the chassis itself, such as the cooling fan, hard disk, and the internal mechanical part of the optical drive, may cause the optical module to loosen, and the manual daily maintenance and repair of the optical module may cause the optical module to loosen and be damaged. In addition, the internal core wire of the wiring harness connected to the optical module for transferring electrical signals is relatively fragile. Once the external force of pulling the wiring harness appears, the wiring harness end plugged into the optical module and the core wire at the end are easily broken, which will lead to the problem of unsuccessful signal transfer. For this reason, a device positioning device for QSFP optical module is proposed. Utility Model Content
