Description

Technical Field

[0001] This utility model relates to the field of magneto-optical switch technology, and in particular to a magneto-optical switch that is easy to install with optical fibers. Background Technology

[0002] Magneto-optic switches are optical switches that utilize the Faraday magneto-optical effect. Because they have no moving parts, they consume little power, are stable and reliable, have a relatively fast switching speed (tens of microseconds), and are relatively simple to manufacture, making them widely used. The disadvantage is that they are not easy to integrate. Magneto-optic switches change the effect of an external magnetic field on the polarization plane of incident polarized light by altering the effect of the magneto-optical crystal, thereby achieving the effect of switching the optical path. Compared with traditional mechanical optical switches, they have advantages such as fast switching speed and high stability. Compared with other non-mechanical optical switches, they have advantages such as low driving voltage and low crosstalk.

[0003] Currently, magneto-optical switches have the following problems when in use: traditional magneto-optical switches are difficult to install with optical fibers, and external impacts can damage internal components, thus affecting the stable operation of the magneto-optical switch.

[0021] In this embodiment, the magneto-optical switch body 102 is disposed on the top of the mounting base 101. A protective mechanism is provided on the outside of the magneto-optical switch body 102. The housing of the magneto-optical switch body 102 can be connected to the mounting base 101 by bolts arranged from bottom to top. A circular hole is provided on the top platform of the mounting base 101. The protective mechanism is used to protect the magneto-optical switch body 102 from impact and improve the safety of internal components.

[0022] The threaded seat 103 is located above the magneto-optical switch body 102 and is screwed into the protection mechanism. The mating seat 104 is located on the top of the housing of the magneto-optical switch body 102 and has a circular insertion cavity in the middle. The connector 105 is detachably connected to the threaded seat 103 and is located on the side of the threaded seat 103 near the mating seat 104. The pin 106 is located at the bottom of the connector 105 and is slidably connected to the mating seat 104. The optical fiber 107 is located on the upper side of the connector 105 and is connected to the pin 106. The external thread end on the threaded seat 103 is screwed into the protection mechanism. A connecting platform is set on the vertical axis, and a circular through hole is set vertically on the connecting platform. The mating seat 104 is directly pre-set on the top of the housing of the magneto-optical switch body 102. A circular insertion cavity is set in the middle to cooperate with the pin 106. The fixing plate of the connector 105 is provided with mounting holes spaced 120° apart. The threaded seat 103 is provided with a mating threaded hole to facilitate the installation of three fastening bolts.

Simultaneously, the mating seat 104 is pre-installed on the top of the magneto-optical switch body 102. During installation, the pin 106 at the bottom of the connector 105 is vertically inserted into the threaded seat 103 to engage with the through hole, ensuring the connector... The three fixing holes on the fixing plate of 105 are aligned with the three threaded holes on the threaded seat 103. Then, the connector 105 is pushed further so that the pin 106 can engage with the circular cavity on the docking seat 104. Finally, the three bolts on the fixing plate of the connector 105 are fixed to achieve convenient installation. The protective sleeve 109, the base plate 108 and the threaded seat 103 work together to provide impact protection for the magneto-optical switch body 102, improving safety and enabling convenient installation of optical fibers in the magneto-optical switch.
