1. An optical module, comprising:
a shell;
a circuit board disposed in the shell;
a light-emitting chip disposed on the circuit board and configured to generate an optical signal;
a lens assembly disposed on the circuit board, covering the light-emitting chip, and configured to change a propagation direction of the optical signal incident to the lens assembly from the light-emitting chip;
an optical fiber ferrule assembly, wherein an end of the optical fiber ferrule assembly is connected to the lens assembly, and the optical fiber ferrule assembly is configured to transmit the optical signal incident to the optical fiber ferrule assembly from the lens assembly; and
a fastener fixing the optical fiber ferrule assembly to the lens assembly, wherein
the fastener includes:
a fastening body;
a first clamping portion disposed at an end of the fastening body and clamped with the optical fiber ferrule assembly; and
a second clamping portion disposed at another end of the fastening body and clamped with the lens assembly;
the lens assembly includes:
a lens base configured to change a propagation direction of the optical signal incident into the lens base from the light-emitting chip;
a plugging portion disposed at an end of the lens base and configured to allow the optical fiber ferrule assembly to be inserted; and
a positioning portion disposed on an outer circumference of the plugging portion, wherein the first clamping portion is clamped with the first optical fiber ferrule and located on a side of the sleeve base away from the lens assembly;
the optical fiber ferrule assembly includes:
a first optical fiber ferrule disposed in the plugging portion;
a second optical fiber ferrule;
an internal optical fiber, an end of the internal optical fiber being connected to the first optical fiber ferrule, and another end of the internal optical fiber being connected to the second optical fiber ferrule;
an optical fiber adapter, the second optical fiber ferrule disposed in the optical fiber adapter; and
a sleeve base sleeved on an outer circumference of the first optical fiber ferrule, wherein the second clamping portion is clamped with the plugging portion and located on a side of the positioning portion away from the optical fiber ferrule assembly; and
the first clamping portion includes:
a first bending segment having a curved structure, a first end of the first bending segment being connected to a first end of the fastening body, and the first bending segment being bent downwards from the first end of the fastening body and in a direction away from the second clamping portion;
a connecting segment having a flat plate structure, a first end of the connecting segment being connected to a second end of the first bending segment; and
a second bending segment having a curved structure, a first end of the second bending segment being connected to a second end of the connecting segment, and the second bending segment being bent downwards from the second end of the connecting segment and in a direction close to the second clamping portion.
