Description

Optical connector {OPTICAL CONNECTOR}

The present invention relates to a field assembly type optical connector that is easy to align connection and assembly without damaging the optical fiber in the optical connection site that requires the connection of the core of the optical fiber and to secure the cable securely to the connection state of the core wire.

In general, the optical connector used for the connection of optical fiber, which is a transmission medium of optical communication, is widely used in optical links such as various communication devices, precision measuring instruments, audio and video devices, sensors, and LC, FC, ST, and SC optical connectors.

Optical connector is an optical device that connects different optical fibers mechanically to match the central axis so that optical communication is possible.The optical connector has a larger connection loss than permanent connection such as fusion splicing but can be easily separated and connected to each other. The advantage of repeatable connection in turn occurs, which is currently used for optical fiber distribution boards or optical end station devices and optical fiber cables or optical fiber cables, or as input / output terminals such as optical measuring devices.

Termination and assembly of optical connectors is mostly done in factories, as polishing requires a high level of skill for the operator. Recently, due to the expansion of FTTH (Fiber To The Home) service, a part of an optical connector is pre-processed and assembled to provide a quick and easy response at the line site when connecting multiple optical lines. On-site assembly type optical connector that can be connected to the optical connector by simple stripping and cutting is used.

However, most optical connectors are often not very suitable for field installation, and the prior art field-assembled optical connectors have epoxy in ferrules to connect the core wires of optical fibers from both sides in the ferrule so that their connection state is firmly fixed. Curable resins such as resins, or adhesives, are used to mount the connectors to the optical fiber.

This process is difficult and time consuming to perform on site. In addition, the operator is unable to determine the connection of the cores, increasing the likelihood of performance degradation or fiber damage due to incorrect assembly.

In addition, the field-assembled optical connector that connects the core wire permanently by using a curable resin is only one-time use and cannot be used repeatedly. In addition, once a connection is made, even if a connection loss occurs, such as misalignment between cores, the connection cannot be corrected, leading to performance degradation.

1 is an exploded perspective view of an optical connector according to an embodiment of the present invention, Figure 2 is a perspective view of an optical connector according to an embodiment of the present invention. 3 is a cross-sectional view taken along the line III-III of FIG. 2, and FIGS. 4A and 4B are views showing the position of the optical fiber according to the rotation state of the clamp ring.

The optical connector according to an embodiment of the present invention includes a clamp 10, a clamp ring 20, a frame 30, a housing 40, a spring including a first body 11 and a second body 12 60) and a stopper 70.

The first body 11 is formed with a receiving groove 111 in which the optical fiber 1 can be accommodated.

The second body 12 is a member that is coupled to the first body 11 and fixes the optical fiber 1 like the first body 11.

The first body 11 is coupled to the second body 12 to form a clamp 10, and the optical fiber 1 is received and fixed inside the clamp 10.

The clamp 10 may be made of a polymeric material such as plant fiber, animal fiber, mineral fiber, artificial fiber fiber, synthetic fiber, glass fiber and artificial protein fiber.

The clamp ring 20 surrounds the outer circumferential surface of the clamp 10 and fixes the first body 11 and the second body 12 so that they do not separate from each other.

The clamp ring 20 is rotatable while being coupled to the clamp 10, and the position of the optical fiber 1 located inside the clamp 10 is adjusted by the rotation of the clamp ring 20.

Referring to FIG. 3, the clamp ring 20 has a pressing protrusion 22 formed therein, and a cross section of an inner side thereof is formed in a circular shape.

In response to the clamp ring 20, the clamp 10 has an outer circumferential surface formed in an elliptical shape. The pressing protrusion 22 is in contact with the second body 12.

The receiving groove 111 of the first body 11 is formed to narrow the width of the receiving groove 111 along the depth direction, as shown in (a) and (b) of FIG.

After arranging the optical fiber 1 in the first body 11 and then coupling the second body 12, the optical fiber 1 is disposed in the receiving groove 111 as shown in FIG. It is fixed by the 11 and the 2nd body 12.

Then, when the clamp ring 20 is rotated, the second body 12 is pressed in the direction of the first body 11 by the pressing protrusion 22, and the optical fiber 1 is accommodated by the movement of the first body 11. The groove 111 moves inside (see FIG. 4B). That is, the position of the center of the optical fiber 1 is moved inside the first body 11 and the second body 12.

In other words, the receiving groove 111 on which the optical fiber 1 is placed is formed to have a different width in the depth direction. Therefore, when the clamp ring 20 is simply coupled to the clamp 10, the optical fiber 1 is placed on the upper side of the receiving groove 111. Then, when the second body 12 is pressed in the direction of the first body 11 according to the rotation of the clamp ring 20, the optical fiber 1 is pressed in the depth direction of the receiving groove 111 of the receiving groove 111 Will move downward.

Accordingly, when the two optical fibers are connected to each other using the connector 80 (see FIGS. 12-15), the cores of the two optical fibers are matched to each other. When the clamp ring 20 is rotated to reach the state of FIG.

Meanwhile, FIGS. 7A and 7B illustrate clamp rings and clamp shapes according to another embodiment.

A corresponding protrusion 124 protrudes from the clamp 10 according to another embodiment, and an outer surface thereof may be formed in an elliptical shape as described above, or alternatively, may be formed in a circular shape or the like. And the pressing projection 22 of the clamp ring 20 is formed wide along the inner circumference of the clamp ring (20).

When the clamp ring 20 is coupled to the outside of the clamp 10, the clamp ring 20 is coupled so that the corresponding protrusion 124 does not interfere with the pressing protrusion 22, as shown in FIG. Let's do it.

Since the clamp ring 20 is rotated using the rotating member 50 as shown in (b) of FIG. 7, the pressing protrusion 22 protruding from the inner surface of the clamp ring 20 is clamped 10. The corresponding projection 124 of the contact. When the pressing protrusions 22 protruding in opposite directions press the corresponding protrusions 124, the second body 12 moves toward the first body 11, and in this process, the second body 12 and the second body 12 are formed. The optical fiber 1 accommodated between the one body 11 is moved to the inside of the receiving groove 111.

Therefore, the center of the optical fiber 1 is moved to the bottom of the receiving groove 111 as compared to when the clamp ring 20 is simply coupled to the clamp 10 so that the optical fibers are connected to each other in contact with the center of the optical fiber housed in another optical connector. Or released.

The configuration in which the optical fiber 1 is moved by the rotation of the clamp ring 20 and the center thereof is not limited is illustrated, and the clamp ring 20 may be rotated to press or release the second body 12. Any structure that belongs to the present invention.

Although not shown, in another example, even when the outer circumferential surface of the clamp is formed in an oval shape and the inner circumferential surface of the clamp ring is formed in a square shape, when the clamp ring rotates, the second body faces the first body according to the coupling angle of the clamp ring and the clamp. You will receive strength. Therefore, the center of the optical fiber can move.

The frame 30 is a member coupled to the outside of the clamp ring 20, the housing 40 is a member coupled to the outside of the frame 30.

The frame 30 has one end and the other end penetrated therein so that the clamp ring 20 can be inserted into the frame 30. The through hole 31 is formed on the side of the frame 30.

The housing 40 is a member that facilitates connection and separation of the optical connector and the connector when connecting the two optical connectors to each other using a connector.

The insertion hole 41 is formed in the side surface of the housing 40 to correspond to the through hole 31.

And a part of the circumferential surface of the clamp ring 20 is formed with a coupling hole (21a).

Referring to FIG. 2, the positions of the coupling hole 21a, the through hole 31, and the insertion hole 41 overlap with each other. That is, the coupling hole 21a and the through hole 31 are exposed to the outside through the insertion hole 41 formed in the housing 40.

Therefore, when releasing the connection of two optical fibers in a state in which two optical connectors are connected through a connector, the clamp ring 20 is rotated by rotating the through hole 31 exposed to the outside through the insertion hole 41 of the housing 40. This rotation allows the position of the optical fiber 1 inside the clamp 10 to be adjusted so that the optical fiber can be easily disconnected while the optical connector is connected to the connector.

Conversely, in order to connect two optical fibers that have been disconnected, by rotating the coupling hole 21a in reverse while the optical connector is connected to the connector, the position of the optical fiber 1 is readjusted. Fibers can be connected with their centers in contact with each other.

In addition, when replacing or repairing the optical fiber, the clamp ring 20 is rotated so that the position of the optical fiber 1 is spaced apart from the first body and the second body as shown in FIG. Therefore, there is no need to separate the optical connector itself when removing or inserting the optical fiber, and also to prevent scratches on the optical fiber or contact with the first and second bodies 11 and 12 when the optical fiber is inserted. Can be.

Therefore, when repairing or replacing the optical fiber, or when connecting or releasing the optical fiber, there is no need to reposition the optical fiber by disconnecting the optical connector itself, and the coupling hole 21a exposed to the outside through the insertion hole 41 is removed. By rotating and rotating the clamp ring 20, the connection and disconnection of the optical fiber can be facilitated.

The rotating member 50 is a member inserted into the coupling hole 21a to easily rotate the coupling hole 21a.

Rotating member 50 includes a coupling body and the coupling portion as shown in Figure 8 (a).

The engaging body is formed in a curved surface so that it can easily contact the finger. However, it may alternatively be formed in a planar shape. In this case, the finger contacts the coupling body and rotates the rotating member inserted into the coupling hole, or by holding the coupling body with a finger to rotate.

One side of the coupling part is connected to the coupling body, and the other side is inserted into the coupling hole 21a. The coupling part is connected to the clamp ring through the coupling hole 21a to easily rotate the clamp ring.

As shown in Figure 7 (a) (b), the coupling portion includes an insertion protrusion (51).

The insertion protrusion 51 is inserted into the coupling hole 21a to couple the rotating member 50 to the coupling hole 21a, and then rotates the rotating member 50 protruding out of the insertion hole 41. The coupling hole 21a formed in the hole 41 can be easily rotated.

On the other hand, the coupling hole 21a is formed in the coupling protrusion 21b.

That is, the coupling protrusion 21b protrudes from a part of the circumferential surface of the clamp ring 20, and the coupling hole 21a is formed by penetrating the central portion of the coupling protrusion 21b.

In this case, the depth of the coupling hole 21a is deepened by the height of the coupling protrusion 21b as compared with simply formed through the circumferential surface of the clamp ring 20. When the depth of the coupling hole 21a becomes deep, a protruding length of the insertion protrusion 51 may be lengthened correspondingly, and in this case, the coupling force between the coupling hole 21a and the insertion protrusion 51 is firm.

In addition, as described above, when the coupling hole 21a is formed in the coupling protrusion 21b, the support protrusion 52 may be further formed on at least one side of the insertion protrusion 51.

When the insertion protrusion 51 is inserted into the coupling hole 21a, the support protrusion 52 is located outside the coupling hole 21a and the rotation member 50 is formed by the insertion protrusion 51 and the support protrusion 52. Is coupled to the coupling hole (21a) is the coupling force between the coupling hole (21a) and the rotating member 50 is more robust, and thus it is easy to rotate the clamp ring 20 using the rotating member (50) It works.

However, the coupling hole 21a is not formed in the coupling protrusion 21b, but may be formed directly on the circumferential surface of the clamp ring 20. In addition, the support protrusion 52 may be omitted. In addition, the coupling holes 21a may be omitted, and only protrusions may be formed on the circumferential surface of the clamp ring 20. In this case, a hole that can be connected to the protrusion is formed in the rotating member 50, and the insertion protrusion 51 may be omitted. Furthermore, any structure, for example, an interference fit structure, a detachable structure using elastic force, and the like that can be detached from the clamp ring 20 by the rotating member 50 can be applied to the embodiment of the present invention.

On the other hand, the rotating member 50 may be coupled to the coupling portion in the same direction in the coupling body.

That is, as shown in (b) of FIG. 8, the coupling part includes an insertion protrusion 51 and a support protrusion 52, and the insertion protrusion 51 is formed to be long in one direction on one side of the coupling body and is supported. The protrusion 52 is formed at an angle substantially perpendicular to the insertion protrusion 51.

Insertion protrusion 51 is formed long in one direction is inserted into the coupling hole (21a) is coupled to the clamp ring 20, the support protrusion 52 is rotated in the outer side of the coupling hole (21a) as the insertion protrusion (51) The coupling force between the member 51 and the clamp ring 20 is firm.

The insertion protrusion 51 is formed to be long in one direction to correspond to the coupling hole 21a so as to be coupled to the coupling hole 21a, and the support protrusion 52 is in contact with the coupling protrusion 21b and to firmly tighten the coupling force. It is formed in the direction perpendicular to the insertion protrusion 51.

And the coupling body is formed to protrude long in the same direction as the insertion protrusion 51 and the support protrusion 52 so that the user can easily grasp and rotate.

However, unlike shown in FIG. 8 (b), even when the coupling body and the coupling part are formed in the same direction, the insertion protrusion 51 is not formed at one side of the coupling body and is formed at a substantially central portion, and the support protrusion 52 is provided. ) May be formed on both sides of the insertion protrusion (51).

The rotating member 50 is detachably connected to the coupling hole 21a, but may be fixed by an adhesive or the like.

That is, an adhesive may be applied to the coupling hole 21a or the rotating member 50 to fix them, or the rotating member 50 may be fixed to the coupling hole 21a by a clamp or the like. In this case, since the rotating member 50 is fixed to the coupling hole 21a, the risk of losing the rotating member 50 is reduced, so that the clamping ring is easily rotated through the rotating member 50, thereby connecting or connecting the optical fiber. Separation can be performed in a short time.

12 to 15 show optical connectors according to other embodiments.

12 and 13 show a state where the optical connector is inserted into the connector for connection with another optical connector, FIG. 14 is a state where the optical connector is inserted into the connector, and FIG. 15 is a side view of FIG.

12 to 15, the optical connector includes a clamp 10 including a first body 11 and a second body 12, a clamp ring 20, a frame 30, a housing 40, and a spring. 60 and a stopper 70.

The clamp 10, the clamp ring 20, the frame 30, the spring 60, the stopper 70, and the housing 40 including the first body 11 and the second body 12 according to the present embodiment. ) Is substantially the same as shown in Figs.

However, the optical connector according to the present embodiment further includes an anti-loosening hole 42 formed to be connected to the insertion hole 41 of the housing 40. After the rotating member 50 located in the insertion hole 41 rotates the clamp ring 20 so that the optical fiber is in the state of FIG. 4 (b), the optical connector is connected to another optical connector (not shown). When coupled to 85, the rotating member 50 is located in the release preventing hole 42 (see Fig. 13-15). In this way, the rotating member 50 is stably fixed during communication by using the optical connector, and furthermore, the connection of the optical fiber is stably maintained.

When the rotation member 50 is located in the release preventing hole 42, when the optical connector is coupled to the connector 80, the hook 85 formed inside the connector 80 is caught by the hook fixing part 35. At the same time, the housing 40 moves toward the connector 80. That is, when the optical connector is coupled to the connector 80, the housing 40 is pulled toward the connector 80, and at the same time, the rotating member 50 located in the insertion hole 41 is relatively moved away from the connector 80. It is fixed to the prevention hole 42. However, in addition to such a method, a variety of methods may be used, such as an operator directly moving the rotating member 50.

The separating member 37 formed in the housing 40 is used to separate the optical connector from the connector 80. Looking at the separation method, when the housing 40 is pulled to the opposite side of the connector 80, the separation member 37 opens the hook 85, so that the hook 85 is easily separated from the hook fixing part 35.

Meanwhile, an exploded perspective view of the clamp ring and the clamp is shown in FIG. 5, and sectional views of the clamp ring and the clamp are shown in FIGS. 6A and 6B.

The clamp 10 is formed with a guide portion 13 extending outwardly in the width direction of the clamp 10 at one end thereof.

5 and 6 illustrate the shape in which both the guide parts 13 are formed in the first body 11 and the second body 12, but any one of the first body 11 or the second body 12 is illustrated. Only one guide portion 13 may be formed.

The clamp ring 20 includes a locking portion 23 formed with a cutting portion 24 penetrated in the width direction of the clamp ring 20 at one end thereof.

When inserting the clamp ring 20 into the clamp 10, the cutting portion 24 of the locking portion 23 is inserted into the guide portion 13, as shown in (a) of FIG. The clamping ring 20 is not interfered with. In addition, each side of the pair of engaging portions 23 formed at one end of the clamp ring 20 abuts the guide portion 13, and the clamp ring 20 is coupled to the clamp 10 along the guide portion 13. Will be.

Hereinafter, with reference to FIGS. 3 to 5 will be described the operation and effect of the optical connector according to an embodiment of the present invention described above.

In the optical connector according to the exemplary embodiment of the present invention, the insertion hole 41 of the housing 40, the through hole 31 of the frame 30, and the coupling hole 21a of the clamp ring 20 overlap each other. The through hole 31 and the coupling hole 21a are exposed to the outside through the hole 41.

Therefore, in a state in which the frame 30 and the housing 40 are coupled to the clamp ring 20, the clamp ring 20 is rotated by rotating the coupling hole 21 a through the insertion hole 41 to thereby clamp the clamp 10. The position of the optical fiber 1 accommodated in the can be adjusted.

In one example, the clamp ring 20 has a circular inner surface and a pressing protrusion 22 formed therein, and the clamp 10 has an elliptical outer surface formed by the rotation of the clamp ring 20. The position of the pressing protrusion 22 is changed to press the second body 12 in the direction of the first body 11.

The movement of the second body 12 is transmitted to the optical fiber 1 accommodated between the first body 11 and the second body 12 so that the optical fiber 1 moves deeply into the receiving groove 111 and thus the optical fiber. The position of (1) is moved so that the two optical fibers are easily connected to or disconnected from each other by being connected with the optical fibers housed in the other optical connector through the connector.

In addition, the guide portion 13 is formed on the outer side of the clamp 10 along the width direction, and correspondingly, the locking portion 23 having the cutting portion 24 cut in the width direction at one end of the clamp ring 20. Is formed.

Therefore, the clamp ring 20 is inserted into the clamp 10 so that the cutting part 24 is positioned at the guide part 13, and the clamp ring 20 is easily inserted into the clamp 10, and the clamp ring 20 is rotated. When the other side of the locking portion 23 is in contact with the guide portion 13 and the rotation is stopped, the rotation angle of the clamp ring 20 is controlled.

Therefore, the clamp ring 20 may not rotate 360 degrees but may rotate only to the extent that the second body 12 presses the optical fiber 1 by the rotation of the clamp ring 20. The rotation angle range of the clamp ring 20 may be changed in various ways depending on the design.

9 is a plan view of a state in which the first body 11 and the second body 12 of the optical connector according to another embodiment are coupled, FIG. 10 is a sectional view taken along the line VII-VII of FIG. 9, and FIG. It is sectional drawing along the VII-VII line | wire of 9.

The optical connector according to another embodiment includes a clamp 10 including the first body 11 and the second body 12, a clamp ring 20, a frame 30, a housing 40, a spring 60, and And a stopper 70.

The first body 11 and the second body 12 in which the optical fiber is accommodated are made of an elastic member, and the spacer protrusion 121 is formed between the first body 11 and the second body 12.

One end of the first body 11 and the second body 12 is spaced apart when the first body 11 and the second body 12 are coupled by the spacer protrusion 121. Therefore, when the optical fiber is accommodated between the first body 11 and the second body 12, it is possible to secure a free space. As a result, scratches such as scratches or foreign matters may be prevented from occurring due to the first body 11 or the second body 12 when the optical fiber is accommodated.

In detail, the first body 11 includes the first body 112 and the first flange portion 113 extending from the first body 112 in a direction away from the first body 112.

The second body 12 includes a second flange portion 123 extending from the second body 122 in a direction away from the second body 122 and the second body 122.

The spacer 121 is formed between the first flange portion 113 and the second flange portion 123. That is, the spacer protrusion 121 is spaced apart from the first body 112 and the second body 122 is formed on one side or the other side of the first body 112 and the second body 122.

It is formed between the first flange portion 113 and the second flange portion 123. Accordingly, when the first body 11 and the second body 12 are coupled to each other, the first flange portion 113 and the second flange portion 123 on which the spacer protrusion 121 is formed are spaced apart from each other. Then, when a force is applied to the first body 11 and the second body 12 through a clamping ring or the like, the second body 122 and the first body by the elastic force of the first body 11 and the second body 12. The 112 may be in contact with each other, and only the second flange portion 123 and the first flange portion 113 on which the spacer protrusion 121 is formed may be spaced apart from each other.

In particular, the second flange portion 123 includes a first extension portion 123a and a second extension portion 123b, and the spacer protrusion 121 is formed on the second extension portion 123b, so that the first body When the optical fiber is inserted between the 11 and the second body 12, the first and second bodies 11 and 12 are spaced apart by the spacer 121 so that the optical fiber can be easily inserted. When a force is applied to the first body 11 and the second body 12, the first body 112 and the second body 122 may be in contact with each other to firmly fix the optical fiber by an elastic force.

However, unlike this, the second extension part 123b may be omitted, and the spacer protrusion 121 may be formed in the first extension part 123a.

9 to 11 illustrate the shape in which the spacers 121 are formed on the second body 12, but may be formed on the first body 11.
