Description

Optical fiber connector, connector assembly and optical communication device

Technical Field

The present application relates to optical communication technology, and in particular, to an optical fiber connector, a connector assembly, and an optical communication device.

Background

With the development of information technology and network technology, optical fibers are increasingly used as media for signal transmission. An optical fiber connector is a device that makes a detachable (movable) connection between optical fibers. Optical fiber connectors typically include an optical fiber for securing the optical fiber. The optical fiber connector can drive the optical fiber to roll back when the optical fiber connector is in butt joint. In the prior art, most of the optical fiber rollback sections are bare fibers without protective sleeves, so that cavities are required to be reserved in the optical fiber connector to ensure that structural damage is avoided when the optical fibers rollback. However, the cavity reserved for fiber backspacing may increase the length of the fiber optic connector in the axial direction of the fiber optic connector.

The optical fiber 601 includes a core 6011 and a protection sleeve 6013 provided over the core 6011.

The present application is not limited to the application of the optical communication system 1000 in an optical network of FTTx, and the optical communication system 1000 may also be applied to a passive optical local area network (PassiveOpticalLAN, POL) or the like.

In some embodiments of the present application, the present application also provides a connector assembly comprising a fiber optic cable 6 and a fiber optic connector 100a, the fiber optic cable 6 being connected to the fiber optic connector 100 a.

Referring to fig. 3, a first embodiment of the present application provides an optical fiber connector 100a for plugging onto an adapter 8. The fiber optic connector 100a supports field assembly. It will be appreciated that the fiber optic connector 100a may also be used for optical interfacing with other optical connection devices.

Referring to fig. 4 and 5 in combination, the optical fiber connector 100a extends along a first direction, and an axial direction of the optical fiber connector 100a is the first direction (e.g., X direction shown in fig. 3-5). The optical fiber connector 100a includes an optical fiber fixing member 20, an elastic member 40, a housing member 60, and an electrical conductor member 80. The optical fiber fixing member 20 is provided to penetrate the housing member 60 for fixing the optical fiber 601 in the optical cable 6. The fiber securing member 20 is capable of optically interfacing with the adapter 8. The elastic member 40 is elastically abutted between the optical fiber fixing member 20 and the housing member 60 for providing an elastic force required when the optical fiber connector 100a is abutted and retracted with the adapter 8. An electrical conductor member 80 is secured to the housing member 60 for securing the first electrical conductor 603 and the second electrical conductor 605 in the fiber optic cable 6. The electrical conductor member 80 is for electrical connection with the conductive terminals on the adapter 8. In some embodiments of the present application, elastic member 40 and electrical conductor member 80 may be omitted.

The fiber securing member 20 includes a first clamping member 22, a second clamping member 24, a resilient clamping member 26, and an unlocking member 28. The first clamping member 22 is disposed opposite the second clamping member 24 in a second direction (e.g., the Y direction shown in fig. 3-5) for clamping the optical fiber 601 in the fiber optic cable 6. The elastic clamping member 26 is sleeved on the first clamping member 22 and the second clamping member 24. Referring to fig. 6, the elastic clamping member 26 is used for clamping the first clamping member 22 and the second clamping member 24. The housing member 60 is sleeved on the first clamping member 22, the second clamping member 24 and the elastic clamping member 26. The unlocking member 28 is connected to the housing member 60, the unlocking member 28 being adapted to open the second clamping member 24 relative to the first clamping member 22.

In some embodiments of the application, the housing part 60 is provided with an operating groove 61. The unlocking member 28 is provided to cover the first holding member 22. The unlocking member 28 is slidably connected to the operation slot 61, and the unlocking member 28 is configured to move in the second direction in the operation slot 61 to apply a force to the second clamping member 24, so that the second clamping member 24 is opened relative to the first clamping member 22. The unlocking member 28 is biased in the second direction towards the second clamping member 24, and is capable of overcoming the elastic force of the elastic clamping member 26, so that the second clamping member 24 is opened relative to the first clamping member 22. The present application is not limited to the connection between the unlocking member 28 and the housing member 60, for example, an opening may be provided in the housing member 60, and when the second clamping member 24 needs to be opened relative to the first clamping member 22, the unlocking member 28 may be inserted into the opening and contact at least one of the first clamping member 22 and the second clamping member 24, and the unlocking member 28 may cause the second clamping member 24 to be opened relative to the first clamping member 22.

When the optical fiber connector 100a is used, the optical cable 6 is assembled to the optical fiber connector 100a, the optical fiber 601 is inserted between the housing member 60 and the first clamping member 22 and the second clamping member 24, and the core 6011 and the protection sleeve 6013 of the optical fiber 601 are clamped and fixed or locked by the first clamping member 22 and the second clamping member 24 due to the elastic force of the elastic clamping member 26.

Referring to fig. 7a, when the second clamping member 24 is opened relative to the first clamping member 22 (which may be referred to as an opened state of the optical fiber fixing member 20), the second clamping member 24 and the first clamping member 22 can form a gap 201. Since the gap 201 is small, the protection sleeve 6013 can still be clamped by the first clamping member 22 and the second clamping member 24 to be locked, and the fiber core 6011 is in a movable state, for example, the fiber core 6011 can move or displace in the axial direction relative to the housing member 60 of the optical fiber connector 100a under the action of an external force. The core 6011 moves in an axial direction, including fiber retraction, relative to the housing member 60 of the fiber optic connector 100a when subjected to an external force.

Referring to fig. 7b, when the second clamping member 24 and the first clamping member 22 are closed (which may be referred to as a closed state of the fiber fixing member 20). The core 6011 and the protection sleeve 6013 can be locked by the first clamp 22 and the second clamp 24. The core 6011 is locked such that the core 6011 is in a significantly immovable state, such as: the core 6011 cannot move or displace in the axial direction with respect to the housing member 60 of the optical fiber connector 100a when subjected to an external force.

Since the fiber fixing member 20 allows the fiber core 6011 to be retracted when in the opened state, there is no need to reserve the fiber retraction space in the axial direction of the fiber connector 100a, which is advantageous for reducing the axial length of the fiber connector 100a, thereby being advantageous for reducing the occupied space of the fiber connector 100a and also for installing the fiber connector 100a in a smaller assembly space.

The user can open the second clamping member 24 relative to the first clamping member 22 by the unlocking member 28, which is convenient for the user.

In some embodiments of the present application, the fiber optic cable 6 is threaded through the housing member 60 of the fiber optic connector 100a, the fiber optic cable 6 including an optical fiber 601, the optical fiber 601 being threaded between the first clamping member 22 and the second clamping member 24. When the second clamping member 24 and the first clamping member 22 are closed, the optical fiber 601 is clamped and fixed by the first clamping member 22 and the second clamping member 24. The optical fiber 601 is movable in the axial direction of the optical fiber connector 100a relative to the first clamp 22 when the second clamp 24 is opened relative to the first clamp 22.

In some embodiments of the application, the optical fiber 601 includes a core 6011 and a protective sleeve 6013 disposed over the core 6011. When the second clamping member 24 and the first clamping member 22 are closed, the core 6011 and the protection sleeve 6013 are clamped and fixed by the first clamping member 22 and the second clamping member 24.

The first clamping portion 224 is connected between the ferrule portion 222 and the first connecting portion 226, and the first clamping portion 224 is used for clamping the optical fiber 601 in cooperation with the second clamping member 24. The first clamping portion 224 is provided with a guide slot 2242 for sliding connection with the unlocking member 28. The first connection portion 226 is for connection with the housing member 60.

The first positioning portion 228 is disposed on the first clamping portion 224, and is configured to be connected to and matched with the second clamping member 24.

The second clamping member 24 includes a second clamping portion 244, a bump 245, a second connecting portion 246, and a second positioning portion 248. The second clamping portion 244 is disposed opposite the first clamping portion 224 along the second direction. The second clamping portion 244 cooperates with the first clamping portion 224 for clamping the optical fiber 601. The bump 245 is disposed on the second clamping portion 244.

In some embodiments of the present application, the bump 245 may be omitted, and the unlocking member 28 may be capable of pushing the second clamping member 24, for example, the height of the second clamping portion 244 may be higher than the height of the first clamping portion 224 in the third direction.

In some embodiments of the present application, the second connecting portion 246 is provided with a second anti-drop boss 2462 at an end remote from the second clamping portion 244.

When the second clamping member 24 is closed relative to the first clamping member 22, the elastic clamping member 26 clamps the first clamping member 22 and the second clamping member 24 by elastic force, so that the core 6011 and the protection sleeve 6013 clamped between the first clamping portion 224 and the second clamping portion 244 are locked. The present application is not limited to the cross-sectional shape of the elastic clamping member 26, and the elastic clamping member 26 may clamp the first clamping member 22 and the second clamping member 24.

Since the first stopper 2244 is accommodated in the second stopper 262, the possibility of the elastic clamping member 26 moving in the axial direction of the optical fiber connector 100a can be reduced.

In some embodiments of the present application, the first limiting portion 2244 may be a limiting groove, and the second limiting portion 262 is a limiting protrusion, and the limiting protrusion is accommodated in the limiting groove.

The number of the first limiting portions 2244 is not limited in the present application, for example, the number of the first limiting portions 2244 may be one, and one first limiting portion 2244 is disposed on one of the first clamping portion 224 and the second clamping portion 244.

The optical fiber connector 100b is used for detachable connection between optical fibers of an optical cable, which may be a pure optical cable, i.e., an optical cable for transmitting optical signals and not for transmitting electrical signals.

The optical fiber connector 100b extends in a first direction. The optical fiber connector 100b includes an optical fiber fixing member 20 and a housing member 60. The fiber securing member 20 includes a first clamp 22, a second clamp 24, a resilient clamp 26, and an unlocking member. The first clamping member 22 and the second clamping member 24 are disposed opposite to each other in the second direction.

At least part of the unlocking member is accommodated in the operation groove 61, and the unlocking member can move in the second direction in the operation groove 61 so as to open the second clamping member 24 relative to the first clamping member 22.

Referring to fig. 16, 17 and 18, a third embodiment of the present application provides an optical fiber connector 100c, and the optical fiber connector 100c provided in the third embodiment is substantially the same as the optical fiber connector 100a in structure, and at least the difference is the structure of the optical fiber fixing member 20 and the structure of the electrical conductor member 80.

The fiber optic connector 100c supports factory termination, facilitating assembly of the fiber optic connector 100c at the factory. The optical fiber fixing member 20 includes the ferrule portion 222 and the connection portion 229, and the connection portion 229 is connected to the electric conductor member 80.

Referring to fig. 19 and 20, a fourth embodiment of the present application provides a fiber optic connector 100d, and the fiber optic connector 100d has a structure substantially identical to that of the fiber optic connector 100a, at least differing in that the second housing 64 of the housing member 60 is at least partially bent with respect to the axial direction of the fiber optic fixing member 20.

The optical fiber connector 100d includes an optical fiber fixing member 20 and a housing member 60. The housing member 60 includes a first housing 62 and a second housing 64, the first housing 62 is sleeved on the optical fiber fixing member 20, the second housing 64 is sleeved on the optical fiber fixing member 20 and connected with the second housing 64, at least part of the second housing 64 is bent relative to the axial direction of the optical fiber fixing member 20, so that the optical fiber 601 forms a bending structure 607 when being inserted into the second housing 64.

Because at least a portion of the second housing 64 is bent axially relative to the fiber securing member 20, when the optical fiber 601 is assembled into the second housing 64 of the fiber optic connector 100d, the optical fiber 601 will conform to the bent second housing 64 to form a bent structure to achieve fiber roll-back control. Since the optical fiber retraction space is not required to be provided in the axial direction of the optical fiber fixing member 20, the axial length of the optical fiber connector 100d can be reduced, and the optical fiber connector 100d can be applied to a space with a relatively limited length.

In some embodiments of the present application, the second housing 64 is an arcuate structure. The second housing 64 has an arc-shaped structure such that the optical fiber 601 forms an arc-shaped bent structure 607 when inserted into the second housing 64. The curved bend 607 reduces the likelihood of the optical fiber 601 being broken while allowing fiber rollback.

The second housing 64 includes a base 642 and a cover 644 covering the base 642, and the base 642 is connected to the first housing 62. Base 642 is used to mount cable 6 and cover 644 is used to cooperate with base 642 to retain cable 6 to second housing 64.

The second tail 6470 snaps together with the first tail 6460 in an axial direction different from that of the fiber-securing member 20. The second tail 6470 snaps together with the first tail 6460 in a direction different from the axial direction of the fiber optic securing member 20 to facilitate assembly of the fiber optic cable to the fiber optic connector 100 d.

In some embodiments of the present application, the optical fiber fixing component 20 includes a first clamping member 22, a second clamping member 24, and an elastic clamping member 26, where the first clamping member 22 and the second clamping member 24 are disposed opposite to each other along a second direction, the elastic clamping member 26 is sleeved on the first clamping member 22 and the second clamping member 24, and the elastic clamping member 26 is used for clamping the first clamping member 22 and the second clamping member 24.

When the second clamping member 24 is opened relative to the first clamping member 22, the fiber fixing member 20 allows the fiber core therein to retract, so that there is no need to reserve a fiber retraction space in the axial direction of the fiber connector 100d, which is further beneficial to reducing the axial length of the fiber connector 100d, thereby being beneficial to reducing the occupied space of the fiber connector 100d and being beneficial to installing the fiber connector 100d in a smaller assembly space.

In the present embodiment, the optical cable 6 has a flat structure, and the optical cable 6 includes a first side 6001 and a second side 6003 which are disposed opposite to each other in the thickness direction of the optical cable 6. When the optical cable 6 is assembled in the second housing 64, the first side 6001 and the second side 6003 are disposed opposite to each other along the first direction, so that when the electrical conductor member 80 is disposed in the optical cable 6, the first electrical conductor 603 and the second electrical conductor 605 are disposed in the optical cable 6 in a stacked manner along the third direction, and the lengths of the first electrical conductor 603 and the second electrical conductor 605 extending in the second housing 64 can be equal, thereby facilitating the installation and reducing the pulling of the first electrical conductor 603 and the second electrical conductor 605.
