1. An optical module, comprising:
a shell;
a circuit board disposed in the shell;
at least one of a light-transmitting chip or a light-receiving chip disposed on the circuit board and electrically connected to the circuit board; the light-transmitting chip being configured to generate an optical signal, and the light-receiving chip being configured to receive an optical signal from an outside of the optical module;
a lens assembly disposed on the circuit board, wherein the lens assembly and the circuit board forming an accommodating cavity in which the at least one of the light-transmitting chip or the light-receiving chip is disposed, wherein the lens assembly comprises:
a lens base which covers the at least one of the light-transmitting chip or the light-receiving chip, and is configured to change a propagation direction of an optical signal incident into the lens assembly; and
a connecting part which includes at least one positioning slot disposed on a surface of the connecting part facing away from the lens base; and
a claw assembly optically connected to the lens assembly, wherein the claw assembly comprises:
a claw which includes at least one positioning protrusion disposed on a surface of the claw facing the connecting part, and the at least one positioning protrusion being inserted into a corresponding positioning slot; and
a through hole penetrating a surface of the claw facing the lens assembly and a surface of the claw facing away from the lens assembly, and the through hole being configured to be connected to an optical fiber outside the optical module;
wherein the claw includes:
a first positioning protrusion disposed on a side of the surface of the claw facing the connecting part and extending toward the connecting part; and
a second positioning protrusion disposed on another side of the surface of the claw facing the connecting part and extending toward the connecting part;
the connecting part includes:
a first positioning slot disposed on a surface of the connecting part facing the claw and corresponding to a position of the first positioning protrusion; and
a second positioning slot disposed on the surface of the connecting part facing the claw and corresponding to a position of the second positioning protrusion;
wherein the first positioning protrusion is inserted into the first positioning slot, and the second positioning protrusion is inserted into the second positioning slot.
