Description

≪ Desc / Clms Page number 1 > Field of the Invention The present invention relates to a field-

The present invention relates to an optical connector, and more particularly, to a field-assembled optical connector capable of interconnecting optical fibers with only an optical connector, even if a separate assembly jig is not provided in the field.

In general, the optical connector is designed to minimize the optical loss through the epoxy bonding and the end polishing process by aligning the ferrule inserted with the core of the optical fiber such that the optical axis of the optical fiber cut according to the predetermined parameter is matched by the operator in the factory. It has been used to install optical cable by attaching optical connector to the finished product type called patch cord. For example, LC, ST, FC and SC optical connectors are used.

Since the patch cord is manufactured at the factory in the form of a finished product with a certain length according to the predetermined parameters, it is possible to use a fiber bundle, a fiber bundle, a fiber bundle in a photoconductor box, There is a limit in the length of the connection between the optical splitter and the optical transmission device and the connection between the optical transmission devices.

Field-assembled optical connectors have been used in which optical connectors provided on both sides of a patch cord are modified into an assembled type so that they can be easily assembled in the field and patch cords of a desired length can be obtained.

Korean Patent Publication No. 2009-0065485 discloses a field-connectable optical fiber connector having a splice element. The disclosed connector includes a housing configured to mate with a receptacle, and a collar body disposed within the housing, wherein the collar body includes a fiber stab disposed within a first end portion of the collar body. The fiber stub includes a first optical fiber. The first optical fiber is mounted in the ferrule and has a first end and a second end adjacent the end face of the ferrule. The collar body further includes a mechanical splice device disposed within the splice device receiving portion of the collar body. A mechanical splice device includes a collar body configured to splice a second end of a fiber stub to a second optical fiber, a fiber jacket having a collar body within the housing and for clamping a jacket portion that, in operation, A backbone including a clamping portion and a boot that can be attached to a portion of the backbone and operate the fiber jacket clamping portion of the backbone when attached to the backbone.

The optical connector constructed as described above can be assembled in the field, but since the mechanical splice device has a structure in which an operator closely contacts the splice element with the operation cap to clamp the optical core, only the core having a diameter of about 125 mu m There is a problem that bonding force is relatively weak and bonding is not smoothly performed.

Also, an optical connector modified to an assembled type is disclosed in Korean Patent Registration No. 10-0507543. The optical connector includes a housing, a plug movably inserted and fixed to the housing, a core aligning member movably inserted into the plug, a fixing member inserted into and fixed to the plug to surround a part of the core aligning member, An optical fiber inserted into the fixing member and engaged with the core aligning member so as to be fixed to the core aligning member and drawn out from the protective covering, And a fastening member for fastening the optical fiber inserted from the protective cover to the optical fiber connecting member by fastening the optical fiber into a clip shape.

This optical connector is difficult to accurately insert the core of the optical fiber into the core insertion hole of the core aligning member because the core of the optical fiber drawn into the optical fiber connecting member is fitted into the core aligning member without separate guiding means. That is, it was very difficult to accurately insert the core having a diameter of about 125 mu m into the core insertion hole having a diameter corresponding to the diameter of the core without any other guiding means. Therefore, there is a problem that it is difficult to accurately connect the core in the core insertion hole of the core aligning member.

Accordingly, the pressing portion 61b can press the cover 50 down while being engaged with the upper portion of the cover 50 by rotation. Although the pressing portion 61b is formed in a flat shape in the present embodiment, the pressing portion 61b is fitted into the upper portion of the cover 50 by rotation, such as a shape protruding in a curved line, Can be manufactured in a variety of shapes.

On the other hand, the grip portion 62 is formed protruding from the outer surface of the rotary ring body 61, and can rotate the rotary ring body 61. [ The grip portion 62 protrudes from the rotary ring body 61 and can form a tuck in a direction opposite to the rotation direction so as to be easily rotated in a state held by the operator.

Hereinafter, the function of the splice unit 30 of the field-assembled connector 10 according to the embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 6 is a sectional view taken along line I - I in the unfolded state of the splice unit of FIG. 4, and FIG. 7 is a sectional view taken along line I - I of the spliced unit of FIG.

1 to 7, the splice unit 30 of the field assembly type connector 10 according to the embodiment of the present invention is divided into a loosened state and a locked state.

The gripped state is a state in which the grip portion 62 is rotated such that the upper surface of the cover 50 is completely positioned at the release portion 61a. It is preferable that the pressing portion 61b is located in a space formed between the projecting portion 53 of the cover 50 and both side portions of the V-shaped groove 43 in the unfolded state. The first core 101 of the first optical fiber or the second core 201 and the jacket portion 202 of the second optical fiber may be inserted between the cover 50 and the V-shaped groove 43 in the unfolded state. At this time, the cover 50 is raised by the first core 101 of the first optical fiber or the second core 201 and the jacket portion 202 of the second optical fiber.

When the grip portion 62 is upwardly moved in the unlocked state, the push portion 61b is positioned on the upper surface of the cover 50 in accordance with the movement of the grip portion 62, The first core 101 of the first optical fiber and the second core 201 and the jacket portion 202 of the second optical fiber can be fixed by being pressed by the grooved portion 43. [ That is, the pressing portion 61b can be pressed against the upper surface of the cover 50 in accordance with the movement of the holding portion 62, so that the pressing portion 61b can press the cover 50 downward.

Therefore, the field-assembled optical connector 10 according to the embodiment of the present invention can fix the first core 101 of the first optical fiber, the second core 201 of the second optical fiber, and the jacket portion 202 at the same time Since the first core 101 of the first optical fiber, the second core 201 of the second optical fiber and the jacket portion 202 are integrally fixed with the splice unit 30, the two optical fibers can be stably fixed can do.

In addition, the field-assembled optical connector 10 according to the embodiment of the present invention allows the cover 50 to be closely contacted with or released from the V-shaped groove 43 by the rotation of the rotary ring 60, The cover 50 which is in close contact with the V-shaped groove 43 can be released even if the jig is not provided.

In addition, the field-assembled optical connector 10 according to the embodiment of the present invention allows the cover 50 to be closely contacted with or released from the V-shaped groove 43 by the rotation of the rotary ring 60, The number of optical fibers can be accurately connected.

It should be noted that the embodiments disclosed in the present specification and drawings are only illustrative of specific examples for the purpose of understanding, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
