Abstract
An optical module having an externally-mounted magnetic ring and a chip positioning angle and a pressing block structure thereof are disclosed. The pressing block structure includes a pressing block. The pressing block includes a pressing block body. The pressing block body is provided with an insertion core positioning hole, a chip accommodating hole, and a magnetic ring accommodating chamber. The chip accommodating hole is provided with at least one positioning angle. The overall assembly accuracy of the optical module is improved, the material cost of the isolator chip is reduced, the positioning of the chip is more accurate, and the occurrence of glue overflow can be avoided.
Claims14
An optical module, comprising a metal front cover, a ceramic sleeve, a pressing block and a ceramic insertion core, the ceramic sleeve being disposed in the metal front cover and fixed by the pressing block, one end of the ceramic insertion core being disposed in the ceramic sleeve, another end of the ceramic insertion core being fixed in the pressing block, the pressing block including a pressing block body, the pressing block body being an integral structure, one end of the pressing block body being formed with an insertion core positioning hole for fixing the another end of the ceramic insertion core, another end of the pressing block body being formed with a chip accommodating hole for accommodating an isolator chip and a magnetic ring accommodating chamber for accommodating a magnetic ring, the chip accommodating hole coaxially communicating with the insertion core positioning hole, the magnetic ring accommodating chamber being arranged around the chip accommodating hole, the insertion core positioning hole being a round hole, the chip accommodating hole being provided with at least one positioning angle for positioning the isolator chip.
