In the description of the embodiments of the present application, the "up", "down", "left", "right", "front", "back" orientation or positional relationship is based on the orientation or positional relationship shown in fig. 1, it is to be understood that these orientation terms are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the present application.
As shown in fig. 1 to 7, an optical module applied to an optical communication device includes a housing assembly 1, an optical interface 2, an electrical interface assembly 3, a light source 4, and a circuit board 5.
The housing assembly 1 includes a receiving cavity (not shown) open at both ends for receiving other components. The circuit board 5 can be fixedly arranged in the accommodating cavity after assembly is completed, and the outer side of the shell component 1 can be in plug-in fit with an external optical fiber, optical communication equipment and the like so as to realize the functions of photoelectric conversion of the optical module and transmitting/receiving optical signals.
The optical interface 2 is coupled with the light source 4; the optical interface 2 is used for outputting continuous light energy emitted by the light source 4; the electrical interface assembly 3 comprises a fixed mount 31 and a float member 32.

The float 32 is electrically connected to the circuit board 5. It should be understood that the electrical connection here may mean that the floating member 32 and the circuit board 5 are abutted by copper foil, lead or metal to realize electrical energy transmission or electrical signal transmission therebetween; in addition, the electrical connection here may also mean that the floating member 32 and the circuit board 5 do not establish a physical connection therebetween, but perform electrical energy transmission or electrical signal transmission in a wireless connection manner by using an electromagnetic induction manner, specifically, the floating member 32 may excite an electromagnetic wave that changes according to a certain rule, the circuit board 5 is provided with an induction device that receives the electromagnetic wave and converts the changed electromagnetic wave into electrical energy, and conversely, the circuit board 5 excites the electromagnetic wave that changes according to a certain rule, the floating member 32 is provided with an induction device that receives the electromagnetic wave and converts the changed electromagnetic wave into electrical energy; this allows electrical energy or electrical signals to be transmitted between the float element 32 and the circuit board 5.
The light source 4 is electrically connected with the circuit board 5, and the floating piece 32 is used for supplying power to the light source 4; i.e. the float 32 provides electrical energy to the light source 4 via the circuit board 5 to excite the optical signal. As known to those skilled in the art, in the field of optical devices, an optical module has an independent package, and the circuit board 5 integrates necessary components for performing optical-electrical signal conversion.
For example, components such as an optical modulator (not shown), a multiplexer (not shown), a demultiplexer (not shown), and the like may be integrated on the circuit board 5. Wherein the optical modulator is configured to apply an electrical signal to the optical energy to output a signal-bearing optical signal. In particular, electrical signals are loaded into optical energy to form a particular form of optical signal, which may change its phase, amplitude, etc. The optical signals with different wavelengths can be combined by the multiplexer to form a path of optical signal. One path of optical signal containing multiple wavelengths is split into multiple optical signals with single wavelength by a demultiplexer.
The floating piece 32 is movably arranged on the fixed seat 31; the float member 32 is floatable with respect to the circuit board 5.

When the electrical connector 83 is plugged into or pulled out from the floating member 32 to generate mechanical stress, and the conductive member 6 is electrically connected to the floating member 32, the conductive member 6 can eliminate the mechanical stress of the floating member 32 through flexible deformation, so that the floating of the floating member 32 relative to the circuit board 5 does not affect the circuit board 5, thereby preventing the mechanical stress from being transferred to the optical interface 2 and improving the coupling precision of the optical interface 2.
The conductive member 6 may be a flexible circuit board according to design requirements; the conductive member 6 may be a multi-core flat cable; the conductive member 6 is a plurality of flexible conductive wires.
