Description

TECHNICAL FIELD [0001] The present invention relates to a ferrule polishing jig for an optical connector and a polishing apparatus employing the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ferrule polishing jig for an optical connector and a polishing apparatus using the same, and more particularly, to a ferrule polishing jig for an optical connector capable of enhancing the supporting force of a ferrule and a polishing apparatus using the same.

Along with the development of communication technology, optical fibers are widely used as information transmission media.

Various optical connectors used for connection between the optical fibers have been developed variously. In general structure, a ferrule inserted through the molten optical fiber can be wrapped around the optical connector.

In addition, the performance of the optical connector is determined by the insertion loss and the reflection loss. In order to suppress the loss, it is very important to grind the end face of the ferrule in contact with each other.

In general, a commercially available ferrule grinding apparatus is capable of grinding a single rotary disk to the polishing jig on which the ferrule is mounted by correspondingly rotating the same.

Further, as disclosed in Korean Patent Laid-Open No. 10-2002-0023828, a polishing jig has a structure in which a 'V' -shaped fixed keyway is formed at the edge along the circumferential direction and the ferrule is supported by the fixed keyway .

However, such a ferrule support structure has a problem in that either the ferrule holding structure is open to the side in the lateral direction between the fixed keyway and the ferrule fastener, and therefore, either of the two ferrules that are not stably supported by the ferrule or supported by the ferrule fastener Is relatively weakly supported.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a ferrule polishing jig for an optical connector having a structure in which a ferrule can be inserted and stably inserted into a through hole, and a polishing apparatus using the same.

In order to accomplish the above object, a ferrule jig for an optical connector according to the present invention has a mounting center groove into which a supporting rod of a polishing apparatus can be inserted, and a plurality of ferrules can be inserted And a through hole penetrating downward from the upper surface is spaced apart from the rim in the radial direction, and an interference which extends outwardly in communication with the through hole in a radial direction perpendicular to the through direction of the through hole A base plate having a hole formed therein; A plurality of bias members threaded through screw holes formed between two adjacent interference holes of the base plate so as to be able to advance and retract relative to the base plate outside the base plate; And first and second interference rods that are inserted into and opposed to the two mutually spaced apart interference holes on the surface of the bias member opposite to the base plate to support and release the ferrule inserted into the through hole.

Preferably, the outer surface of the base plate on which the interference hole is exposed is surface-treated in a multifaceted manner so that two adjacent interference holes are formed on the same surface, and 24 through holes are formed.

According to another aspect of the present invention, there is provided a ferrule polishing apparatus for an optical connector, comprising: a main body; A rotating table rotated by a driving unit provided on the main body and having a polishing pad mounted on an upper surface thereof; And a polishing jig supported by a support rod formed in the main body and opposed to the rotary table, and to which a ferrule to be polished is inserted and mounted.

The ferrule polishing jig for an optical connector according to the present invention and the polishing apparatus using the same provide an advantage that the ferrule can be stably supported.

1 is a side view schematically showing a polishing apparatus to which a polishing jig according to the present invention is mounted,
FIG. 2 is a perspective view showing a polishing jig mounted on the polishing apparatus of FIG. 1,
FIG. 3 is a plan view showing a state in which the biasing member is fully engaged with the polishing jig of FIG. 2;

Hereinafter, a ferrule polishing jig for an optical connector and a polishing apparatus using the same according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view schematically showing a polishing apparatus to which the polishing jig according to the present invention is attached, FIG. 2 is a perspective view showing a polishing jig mounted on the polishing apparatus of FIG. 1, And the bias member are all coupled together.

1 to 3, a polishing apparatus 100 according to the present invention includes a main body 110, a rotary table 120, and a polishing jig 150.

The rotary table 120 is provided on the main body 110 and is rotated by a driving part 115, for example, a motor, and a polishing pad 125 is mounted on the upper surface.

The main body 110 facing the rotary table 120 is provided with a support rod 118 extending downward to support a polishing jig 150 to be described later.

The polishing jig 150 is adapted to be inserted with the ferrule 10 to be polished.

The polishing jig 150 includes a base plate 151, a bias member 155, and first and second interference bars 157 and 158.

The base plate 151 is formed with a mounting center groove 152 into which a support rod 118 can be inserted at the center of an upper surface thereof and is provided with a plurality of ferrules 10 penetrating downward from an upper surface thereof And the through holes 153 are formed so as to be spaced from each other along the radial direction to the inside spaced apart from the edge.

In the illustrated example, the base plate 151 is formed in a polygonal shape having a top surface and a side surface orthogonal to the bottom surface and having 12 surfaces along the circumferential direction, and two through holes 153 corresponding to each surface And a total of 24 through holes 153 are formed.

That is, the outer surface of the base plate 151 on which the interference hole 154 is exposed is subjected to surface treatment so that two adjacent interference holes 154 are formed on the same surface.

Each of the through holes 153 of the base plate 151 extends outwardly so as to communicate with the through holes 153 in the radial direction perpendicular to the through direction of the through holes 153 An interference hole 154 is formed.

The biasing member 155 is formed so as to be movable in a direction in which the biasing member 155 is in contact with the base plate 151 from the outside of the base plate 151.

The biasing member 155 includes a block body 155a and a block body 155a which are formed in a rectangular shape and are screwed together through a threaded hole 159 formed between two adjacent interference holes 154 of the base plate 151 And is formed into a forward / backward bolt 155b.

The biasing member 155 is advanced or retracted toward or away from the base plate 151 in accordance with the rotation direction of the advancement bolt 155b.

A total of nine bias members 154 may be provided corresponding to the respective surfaces.

The first and second interference bars 157 and 158 protrude from the base plate 151 of the block member 155a of the bias member 155 so as to be spaced apart from each other.

The first and second interference rods 157 and 158 are inserted into the two opposing interference holes 154 so that the ferrule 10 inserted into the through hole 153 can be supported and released by interference Respectively.

Therefore, when the polishing jig 150 has the flange in the through hole 153 and the ferrule 10 is inserted into the ferrule 10 by inserting the ferrule 10 to which the optical fiber is connected, It is only necessary to perform the grinding operation by mounting it on the main body 110 after being made to be pressed and supported by the rods 157 and 158.

According to the ferrule polishing jig for optical connector and the polishing apparatus using the same, the ferrule can be stably supported and processed.
