Active optical cable connector, active optical cable assembly and photoelectric conversion unit

Abstract

The invention relates to an active optical cable connector, an active optical cable assembly and a photoelectric conversion unit. The active optical cable assembly comprises an active optical cable and active optical cable connectors arranged at two ends of the active optical cable, wherein each active optical cable connector comprises a connector shell assembly and a photoelectric conversion unit arranged in an inner cavity of the connector shell assembly; each photoelectric conversion unit comprises printed boards and a support part arranged between the printed boards, wherein the printed boards are arranged from front to back at an interval; and a fastening device is used for tightening or clamping the printed boards along the front and back direction, so that the printed boards are separated by dismantling the fastening device when the printed boards need to be repaired in the using process, and individual printed boards can be inspected, repaired or exchanged, thereby improving the repair performance of the active optical cable connectors.

Description

technical field [0001] The invention relates to an active optical cable connector, an active optical cable assembly and a photoelectric conversion unit. Background technique [0002] Optical fiber has been widely used in the communication industry due to its light weight, low loss, anti-electromagnetic interference and high transmission efficiency. Initially, optical fibers were connected by optical fiber connectors, but it was found that the contamination at the connection end faces of the optical fiber connectors would increase the loss of the optical fiber lines and even damage the optical fiber lines during use. In order to avoid the occurrence of the above situation, the user needs to check and maintain the optical fiber line within a fixed period through special instruments, which will consume a lot of manpower and material resources. [0003] The active optical cable connector strips the photoelectric conversion circuit from the device and integrates it into the conn...

Problems solved by technology

For example, an active optical cable connector disclosed in a Chinese patent application with the application publication number of CN104330857 A and the application publication date of 2015.02.04, the connector includes a connector housing assembly, and the front end of the active optical cable connector is an electric plug. The electric plug housing and the connector housing constitute the connecting housing assembly of the active optical cable connector. The connector housing is rotated and equipped with a connecting nut, and the connecting nut passes through the external thread on the outer circumference of the rear end of the electric plug housing. Cooperate to connect the electric plug shell and the connector shell together, the photoelectric conversion unit is installed in the inner cavity of the rear end of the electric plug shell, the front printed board of the photoelectric conversion unit is welded and fixed on the contact piece of the electric plug, and the rear printed The printed board is fixed by glue filling, so that if the printed board fails during use, it cannot be disassembled and repaired

There is also an active optical cable connector that glues the photoelectric conversion unit into a whole and installs it into the connector housing, such as figure 1 As shown, the photoelectric conversion unit includes a printed board and an annular gasket. The annular gasket is arranged between adjacent printed boards and fixed by epoxy glue. During the bonding process, the relative position of the printed board and the annular gasket The position is guaranteed by tooling or positioning pins set between the ring gasket and the printed board. When this active connector is assembled, the consistency of the bonding process is not easy to guarantee, and the gasket and the printed board are not easy to guarantee during gluing. The gap between the boards is uneven, and it is easy for the glue to flow to the non-adhesive surface, causing a quality hazard; in addition, although the photoelectric conversion unit can be taken out of the connector housing as a whole, it still needs to be heated when the ring gasket is removed The photoelectric conversion unit makes the epoxy glue loose, and the electrical components on the printed board are easily damaged during the heating process, resulting in poor rework performance of the active optical cable connector
