Abstract
An optical module includes: an optical assembly, including a light receiving assembly and/or a light transmitting assembly; a printed circuit board, on which the optical assembly is mounted; an adapter, used for docking with external connectors, wherein the adapter is configured to fit the optical assembly and to be fixed to the printed circuit board, and the adapter includes a metal part and a plastic part; and a conductive shell, used for accommodating the printed circuit board, the optical assembly, and the adapter, the conductive shell being electrically connected to the metal part of the adapter.
Claims23
An optical module, comprising:
- an optical assembly, including at least one of a light receiving assembly or a light transmitting assembly;
- a printed circuit board, on which the optical assembly is mounted;
- an adapter, used for docking with external connectors, wherein the adapter is configured to fit the optical assembly and to be fixed to the printed circuit board, the adapter including a metal part;
- and
- a conductive shell, for receiving the printed circuit board, the optical assembly, and the adapter, the conductive shell being electrically connected to the metal part of the adapter,
- wherein the metal part includes a metal base and a metal frame located on the metal base,
- a light-transmitting opening is surrounded by the metal frame and the metal base, and
- the entirety or portions of the metal base and metal frame are electrically connected to the conductive shell.
An assembly method for an optical module, comprising:
- providing a printed circuit board, and mounting an optical assembly on the printed circuit board, the optical assembly including at least one of a light receiving assembly or a light transmitting assembly;
- forming an adapter by a process of insert molding, the adapter including a metal part and being used for docking with external connectors;
- fixing the adapter to the printed circuit board using the optical assembly as a position reference;
- and
- installing a conductive shell to an outside of the printed circuit board to form the optical module,
- wherein the metal part includes a metal base and a metal frame located on the metal base,
- a light-transmitting opening is surrounded by the metal frame and the metal base, and
- the entirety or portions of the metal base and metal frame are electrically connected to the conductive shell.
An optical module, comprising:
- a conductive shell defining a space;
- a printed circuit board disposed in the space;
- an optical assembly mounted on the printed circuit board;
- an adapter configured to couple an external connector to the optical assembly, wherein the adapter is disposed in the space, secured to the printed circuit board, fitted with the optical assembly, and electrically connected to the conductive shell.
