Abstract
Provided in the present disclosure is an optical module, including: an upper conductive layer, a lower conductive layer, and an intermediate conductive layer on a circuit board. The upper conductive layer is provided with a first power supply pin, a second power supply pin, and a dummy pin. The intermediate conductive layer is provided with a power supply line. A third through hole is formed below the second power supply pin, and a first through hole is formed below the dummy pin. The third through hole and the first through hole are respectively connected to the power supply line. The present disclosure can prevent secondary power-on.
Claims14
An optical module, comprising:
- an upper shell;
- a lower shell, covering the upper shell to form a cavity;
- and
- a circuit board, located in the cavity and comprising an upper conductive layer, a lower conductive layer, and an intermediate conductive layer located between the upper conductive layer and the lower conductive layer of the circuit board,
- wherein the upper conductive layer is provided with:
- a first power supply pin, configured to be connected to a first terminal of a host computer;
- a second power supply pin, configured to be connected to a second terminal of the host computer, and having a same voltage as the first power supply pin;
- and
- a dummy pin, located between the first power supply pin and the second power supply pin, wherein there is a gap between the first power supply pin and the dummy pin;
- there is a gap between the second power supply pin and the dummy pin;
- the intermediate conductive layer is provided with a power supply line;
- the second power supply pin is connected to the power supply line;
- and
- the dummy pin is connected to the power supply line.
