In optical communication technology, optical modules are tools for converting optical signals and electrical signals, and are one of the key devices in optical communication equipment. With the development of optical communication technology, the transmission rate of optical modules is continuously improved. CONTENT OF THE UTILITY MODEL

[0003] Some embodiments provide an optical module, which facilitates the assembly of the optical module.

[0004] Some embodiments provide an optical module, which comprises an upper shell;

[0005] A lower shell is connected to the upper shell in a covering manner; the lower shell comprises a bottom plate, which is away from the upper shell; the bottom plate is formed with an unlocking through hole;

[0006] An unlocking component is assembled to the lower shell; the unlocking component comprises:

[0007] A driving member is assembled to one end of the lower shell; the driving member comprises a driving rod, which is assembled to the lower shell and can rotate on the lower shell; the driving rod is formed with a driving portion, which protrudes from the surface of the driving rod;

[0008] A locking member is arranged outside the bottom plate; one end of the locking member is assembled to the driving rod and covers the driving portion, and the other end of the locking member is located above the unlocking through hole; the top of the other end of the locking member is formed with an engaging portion; the rotation of the driving rod lifts one end of the locking member and sinks the other end of the locking member into the unlocking through hole;

[0009] An upper cover is assembled to the lower shell and covers the locking member; the upper cover is formed with an engaging through hole, which is sleeved on the engaging portion.

[0010] One of the above technical solutions has the following advantages or beneficial effects: the unlocking component includes a driving member, a locking member and an upper cover. The driving member includes a driving rod, which is assembled and connected to the lower shell and can rotate on the shell. A driving part is formed on the driving rod, and the driving part rotates with the driving rod. An unlocking through hole is formed on the base plate, and the locking member is arranged on the outer side of the base plate. One end of the locking member is assembled and connected to the driving rod, and the other end of the locking member is located above the unlocking through hole, and a clamping part is formed on the other end of the locking member. The upper cover covers the locking member, and a clamping through hole is provided on the upper cover, and the clamping through hole is sleeved with the clamping part. When the optical module is inserted into the cage, the top of the clamping part protrudes from the clamping through hole, and the clamping part can fix the optical module in the cage of the host computer. The drive unit protrudes from the surface of the drive rod. When the drive rod drives the drive unit to rotate, the drive unit gradually contacts one end of the locking member, lifting it and causing the other end of the locking member to sink toward the unlocking hole. The top of the engaging unit is lower than the top of the engaging hole, changing the connection between the engaging unit and the cage, releasing the optical module from the host computer.

The first connecting portion is provided with a first connecting groove, and the second connecting portion is provided with a second connecting groove. The first connecting groove and the second connecting groove are assembled and connected to the driving rod, which not only facilitates the assembly connection between the driving rod and the lower shell, but also facilitates the rotation of the driving rod.

However, the embodiments described are only some of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present disclosure are within the scope of protection of the present disclosure.

[0059] Unless otherwise required by the context, the term "comprises" in the specification and claims is to be construed as open, inclusive, meaning "including but not limited to"; the terms "first", "second" are not to be construed as indicating or implying relative importance or indicating a quantity of upper limit; the term "multiple" means two or more; the term "connected" should be broadly understood, for example, "connected" can be fixed connection, or detachable connection, or integral, can be directly connected, or indirectly connected through intermediate media; the use of the terms "adapted to" or "configured to" means open and inclusive language, which does not exclude devices adapted to or configured to perform additional tasks or steps; the terms "parallel", "vertical", "same", "consistent", "flush" and the like are not limited to absolute mathematical theoretical relationship, but also include acceptable error range generated in practice, and also include differences based on the same design concept but due to manufacturing reasons.

[0060] In optical communication technology, in order to establish information transmission between information processing devices, information is loaded onto light, and the transmission of information is carried out by using the propagation speed of light. Such information-loaded light is optical signal. The optical signal can reduce the loss of optical power when transmitted in optical information transmission equipment, and realize long-distance transmission of optical signal. At the same time, the cost of optical information transmission equipment such as optical fiber is lower than that of electrical information transmission equipment such as copper wire. Therefore, optical communication technology can realize high-speed, long-distance and low-cost information transmission.

[0061] Information processing devices usually include optical network terminal (ONU), gateway, router, switch, mobile phone, computer, server, tablet computer, television and the like, and optical information transmission equipment usually includes optical fiber and optical waveguide and the like. The signal that can be recognized and processed by the information processing device is electrical signal, while the optical communication technology uses optical signal for transmission, which requires optical module to convert optical signal and electrical signal.

[0062] The optical module can realize the mutual conversion between the optical signal and the electrical signal between the information processing device and the optical information transmission equipment. In some embodiments, at least one of the optical signal input end or the optical signal output end of the optical module is connected with an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected with an optical network terminal; a first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; a second electrical signal from the optical network terminal is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber.

[0063] Because multiple information processing devices can transmit information via electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all of them. Here, the information processing device directly connected to the optical module is also referred to as the optical module's host computer. Furthermore, the optical signal input or output end of an optical module is referred to as an optical port, while the electrical signal input or output end of an optical module is referred to as an electrical port.

The second electrical signal from the host computer 100 is transmitted to the optical module 200, the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101. The second optical signal is transmitted in the optical fiber 101 to the remote information processing device 1000.

[0071] In some embodiments, the first optical signal from the remote information processing device 1000 propagates through the optical fiber 101, the first optical signal from the optical fiber 101 is transmitted to the optical module 200, the optical module 200 converts the first optical signal into a first electrical signal, the optical module 200 transmits the first electrical signal to the host computer 100, the host computer 100 generates a fourth electrical signal according to the first electrical signal, and the fourth electrical signal is transmitted to the local information processing device 2000.

Figure 5A and Figure 5B As shown, in some embodiments, the unlocking component 600 may include a locking member 630, which is located outside the bottom plate 2021. Exemplarily, the locking member 630 includes a locking body 631, and a locking portion 632 is provided on the top of the locking body 631 for locking the cage 106.

[0097] In some embodiments, the unlocking component 600 may include a driver 610 that is assembled and connected to the lower housing 202 and can rotate around the assembly point between the driver 610 and the lower housing 202. The driver 610 is assembled and connected to a locking member 630. The rotating driver 610 can drive the locking member 630 to move, thereby unlocking the engaging portion 632 from the cage 106, thereby allowing the optical module 200 to be separated from the cage 106. Exemplarily, the driver 610 is an annular structure and is sleeved on an end of the lower housing 202.

[0098] In some embodiments, the unlocking component 600 may include an upper cover 620, which is assembled and connected to the lower housing 202.

[0099] In some embodiments, the unlocking component 600 can include an elastic member 640, which elastically supports the locking member 630. When it is needed to unlock the optical module 200, an external force rotates the driving member 610, which moves away from the initial position, and drives the locking member 630 to move, which compresses the elastic member 640. When the external force is reduced or removed, the elastic member 640 elastically recovers, and the locking member 630 returns to the initial position of the locking member 630, and the driving member 610 reversely rotates, and returns to the initial position of the driving member 610. For example, the elastic member 640 can be a spring, one end of which is connected to the lower housing 202, and the other end of which is connected to the locking member 630.

[0100] In some embodiments, the unlocking component 600 can include a fixing member 650, which fixedly connects the upper cover 620 and the lower housing 202. For example, the fixing member 650 can be a bolt, a screw, or the like.

[0101] Figure 5C FIG. 6 is a partial schematic view of a lower housing according to some embodiments.

Since the first supporting seat 206 binds the first connecting column 634 and the second supporting seat 207 binds the second connecting column 635, as the lifting part 638 is lifted, the clamping part 632 is lowered together with the other end of the locking body 631. When the driving member 610 is rotated to a preset position, the top of the clamping part 632 is lower than the top surface of the second upper cover body 624, so that the connection state of the locking elastic sheet 1061 and the clamping part 632 is changed to release the fixation of the light module 200 and the upper machine. The driving member 610 is pulled to extract the light module 200 from the cage 106.

[0148] The other end of the locking body 631 sinks the elastic member 640. When the force for rotating the driving member 610 is reduced or removed, etc., the elastic member 640 restores the other end of the locking body 631 to be lifted, so that the engaging portion 632 restores to the initial position, and the lifting portion 638 sinks to restore to the initial position.

[0149] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present disclosure, but not to limit them; although the present disclosure has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
