Description

[Detailed Description of the Invention] The present invention relates to an optical connector for connecting fibers together.

In recent years, optical communications have begun to replace electrical communications.

In this optical communication, as in the case of electric communication, a connector is required to connect fibers together.

Conventionally, connectors such as those shown in Figures 1a and 1) have been used.

That is, the adapters 3a, 3b are held by the main bodies 1, 2 integrated by screws 12.13, and the adapters 3a, 3
Insert the sleeves 4 and 5 holding the end of the fiber 8°9 into the cavity formed by b, and connect the cap nut 6.7 and the main body 1,
It has a configuration in which two threaded portions 1a and 2a are combined.

The adapters 3a and 3b are individually separable, and have a semicircular cross section as shown in b, and have semicircular grooves 3a' and 3b, respectively.
3b' is formed.

Note that 10.11 is a washer.

In such a configuration, since the sleeves 4 and 5 are inserted into the cavities formed by the grooves 3a' and 3b', the diameter of the cavities is larger than the diameter of the sleeves, so there is a gap between the sleeves and the adapter. There is something to play with.

As a result, the centers of the sleeves 4 and 5 inserted into the cavity did not coincide, resulting in large insertion and loss of light.

In addition, in order to match the centers, trial and error must be repeated, which is a disadvantage that it is time-consuming.

The purpose of the present invention is to eliminate such drawbacks, and the purpose is to insert sleeves that fixedly hold the ends of optical fibers into an adapter, and to attach screws formed on the main body that holds the adapter. In an optical connector in which a nut is engaged from the snob side, the outer surface of both ends of the adapter is tapered and divided in the axial direction, and the part where one sleeve contacts each other has a ■-shaped cross section, and the other end has a taper. This is achieved by an optical connector which is circular and is characterized in that a washer that engages with the taper is provided between the nuts.

The present invention will be described in detail below based on examples.

Figures 2a and l) are diagrams showing an embodiment of the present invention, and 14
, 15 is an adapter, 16.17 is a washer, 14' is a round groove,
15' is a groove, and 14a and 15a are tapered parts.

In the present invention, tapered portions 14a are provided at the ends of the adapters 14 and 15 in order to eliminate play between the adapter and the sleeve and to easily align the centers of the sleeves.
15 a, and the groove to be formed in the adapter 15 is called groove 1.
5', and a tapered portion 14a on the sleeve 4, 5 side.

15a was provided with washers 16 and 17 that can be combined.

Next, the operation of such a configuration will be described.

The adapters 14, 15 are held in the bodies 1, 2 in a conventional manner.

Next, the sleeves 4 and 5 are inserted into the cavity formed by the round groove 14' and the square groove 15', and the cap nut 6.7 is engaged with the threaded portions 1a and 2a formed in the main body 1.2.

This allows the washer 16, 17 to be attached to the tapered portion 14 of the adapter.
a, 15a, and applies a force to the adapter 14, 15 to tighten the snobs 4, 5.

Therefore, when the cap nut 6.7 and the threaded portions 1a, 2a are completely mated, the V-groove 15' and the sleeve 4.degree. 5, in particular, are in complete contact with each other and there is no play.

Therefore, the center axes of the sleeves 4 and 5 are perfectly aligned.

As described above, according to the present invention, it is possible to align the central axes of the sleeves simply by inserting the sleeves into the cavities formed by the adapters and tightening them with cap nuts.

[Brief explanation of the drawing]

Figure 1 a, l) shows a conventional optical connector, Figure 2
Figures a and t) are diagrams showing examples of optical connectors according to the present invention. In the figure, 1 and 2 are the main body, 4 and 5 are sleeves, 14.15 is an adapter, and 16.17 is a washer.

Claims (1)

[Scope of utility model registration request] An optical connector in which a pair of sleeves holding fixed ends of optical fibers are inserted oppositely into an adapter, and a screw formed in a main body holding the adapter is engaged with a nut from the sleeve side. A taper is formed on the outer surface of both ends of the nut, and the nut is divided in the axial direction, the section where one of the snobs contacts is shaped like a square, the other is circular, and a washer that engages with the taper is provided between the nuts.
